However, the inventions in Patent Documents 1 to 9 are primarily used for fixed-point lighting, surveillance cameras, etc., making it difficult to expand to other uses.

In Patent Document 2, although the solar panel can be folded using a hinge, the support structure for the solar panel is weak and vulnerable to wind pressure, making it unsuitable for civil engineering and construction work.

In Patent Document 3, the support structure for the solar panel is weak, making it unsuitable for civil engineering and construction work. Although the lighting fixture can be adjusted vertically and horizontally, these adjustments must be made separately, making the operation cumbersome, and the lighting range is limited because the post is fixed to the base plate.

In Patent Document 5, the support structure for the solar panel is weak, making it unsuitable for civil engineering and construction work. The lighting fixtures must be rotated vertically and horizontally, and their height and tilt angle must be adjusted separately, making operation cumbersome, and the lower support tube is fixed to the dolly, limiting the lighting range.

The first objective of the mobile power supply device of the present invention is to be applicable to many uses, such as communication functions, monitoring functions, ventilation functions, cooling functions, and/or lighting. The second objective is to make the overall structure compact while maintaining the support strength and stability of the solar panel. The third objective is to be able to expand the range of the location and functions of the electricity users.

The invention to solve the above problem is a mobile power supply device comprising: a wheel section; a three-dimensional structure section provided on the wheel section and having an attachment section; a solar panel connected to the three-dimensional structure section so that the elevation angle can be changed; an arm having one end and the other end, the one end of which is rotatably attached to the attachment section and which can be in either a folded state or an unfolded state with respect to the attachment section; a lockable rotation mechanism that locks the arm in a predetermined position; and a power supply section that stores electricity generated by the solar panel, the other end of which has a fixing section that can be detachably connected to a support, an electricity user body can be fixed to the support, and electricity can be supplied to the electricity user body from the power supply section.

This configuration allows the arm to be in either a folded or unfolded state relative to the mounting part, expanding the range of movement of the arm. The support can be removed from the fixed part, allowing the electricity user to be used in a location away from the mobile power source.

The "power supply unit" referred to here is preferably a portable power supply. The portable power supply preferably has, for example, a 100V AC power terminal, a USB terminal capable of supplying power, a 12V DC terminal, etc.

The term "electricity users" refers here to things that use electricity to achieve a specific purpose. Examples include lighting, mist generators, air blowers (electric fans, etc.), video equipment (surveillance cameras, etc.), wireless communication devices, etc.

Examples of the "fixing part and the support being detachably connected" include a configuration in which the fixing part is detached using a magnetic body, a configuration in which the fixing part is detached using a fastener, etc.

It is preferable that a magnetic body is provided at the base of the support so that it can be attracted to the fixed part, which is the object to be attracted. This configuration makes it easy to attach and detach the support to and from the fixed part, greatly improving workability.

The mounting portion is U-shaped in a plan view, and has a first member, a second member, and a handle that connects the first member and the second member, which are attached to the three-dimensional structure in a predetermined direction, and the arms are preferably provided in pairs on the left and right of the first member and the second member, and rotate outward relative to the side surfaces of the first member and the second member. This configuration makes it easier to move the mobile power supply device and rotate the arms.

The three-dimensional structure is a truss structure in side view, has a bottom surface, symmetrical inclined portions connected to the bottom surface, and a horizontal portion connecting the upper portions of the inclined portions, and it is preferable that, in the stored state of the solar cell panel, the support and the electricity utilization body are removed from the fixed portion, the extension mechanism connecting the solar cell panel is driven, and the extension mechanism is slid to fold the solar cell panel and arrange it along the axial direction of the inclined portion of the truss structure. With this configuration, the entire mobile power supply device can be made compact when stored. It is possible to prevent twisting and deformation of the three-dimensional structure through the solar cell panel due to wind pressure.

It is preferable that a power supply box, which is electrically connected to the power supply unit and has an output terminal, is provided on the first member and/or the second member. With this configuration, the connecting portion serves to reinforce the truss structure and to fix the power supply box, making it easier to access the power supply.

It is preferable that one end of the telescopic device is connected to the first member and/or the second member, and the other end is connected to the solar panel, so that the elevation angle of the solar panel can be changed. With this configuration, the connecting part can also play a role in assisting in changing the elevation angle.

It is preferable that the bottom portion has a base plate on which the wheel portion is attached, and the power supply portion is fixed onto the base plate so as to be present within the internal space of the three-dimensional structure portion.

This configuration is simple and resistant to wind pressure. It prevents twisting and deformation of the three-dimensional structure caused by wind pressure through the solar panel. The center of gravity is stable, making it easier to attach the cover.

Preferably, the portable power supply has a first cover that covers the top, front, and back of the power supply unit, and a pair of second covers that cover the sides of the power supply unit, and the second covers are attached to the bottom surface via hinges so that they can be raised and lowered. With this configuration, the power supply unit can be prevented from being stolen by locking the second cover. This makes it easier to maintain the portable power supply.

Preferably, the support includes a pole having the mounting portion to which the electric user, which operates upon receiving electricity, is attached, a fixed support portion that supports the pole so that it can be raised and lowered and can maintain the raised and lowered position of the pole, a base portion that supports the pole via the fixed support portion, and at least a pair of magnetic bodies that are fixed to the underside of the base portion and attract the object to be attracted, and the magnetic bodies are detached from the fixed portion and attracted to the object to be attracted.

With this configuration, the electric user can be easily installed in a stable state by attaching the magnetic body to the fixed part. The electric user can be used in a remote location by detaching the magnetic body from the fixed part. The support and the electric user can be easily transported and moved. The weight can be reduced by making the base part necessary for stable placement the object to be attached.

Preferably, the base portion has an upper plate and the magnetic body is fixed to the lower surface of the upper plate.

With this configuration, the magnetic bodies are fixed to the underside of the upper plate, so the support can efficiently resist external forces acting in a specific direction (the direction in which the pair of magnetic bodies are arranged).

Preferably, the base portion has a lower plate that is rotatably connected to the upper plate, the magnetic body is fixed to the underside of the lower plate, and can take a first position where the upper plate and the lower plate intersect, and a second position where the upper plate and the lower plate overlap or are aligned in the same longitudinal direction.

With this configuration, the base can take a first position where the upper and lower plates intersect, and a second position where the upper and lower plates overlap or are aligned in the same longitudinal direction, so that the shape of the fixing part can be taken into account to adequately resist external forces acting on the support.

Preferably, the support device includes a stand that adsorbs the base portion , the stand having an upper stand plate and a lower stand plate rotatably connected to the upper stand plate, and can take a first position where the upper stand plate and the lower stand plate intersect, and a second position where the upper stand plate and the lower stand plate overlap or have their longitudinal directions aligned in the same direction.

With this configuration, the work support tool can be stably installed on the installation surface by adsorbing the base and the stand when the tool is in the first position. Also, by adsorbing the base and the stand when the tool is in the second position, the shape can be made compact.

Preferably, the support pillars are undulating in the longitudinal direction.

With this configuration, the support poles can be laid down in the longitudinal direction, making the overall shape compact. This simplifies storage and improves transportation efficiency.

The electrical user can be positioned at least in a first position where it comes to rest at a position lower than the three-dimensional structure, in a second position where it comes to rest at a position higher than the three-dimensional structure, and in a third position where it comes to rest with the arm extended in the left-right direction of the three-dimensional structure.

This configuration allows the electrical user to be positioned over a wide range of areas, up and down, front and back, left and right, of the three-dimensional structure, increasing the freedom of positioning of the electrical user.

When in a vertical position, the electrical user body is preferably 1.5 to 4 times the height of the three-dimensional structure.

With this configuration, the position of the electricity user can be adjusted over a wide range in the vertical direction compared to the size of the three-dimensional structure and the solar panel.

The arm is 0.7 to 2 times the depth of the three-dimensional structure in the front-to-rear direction.

With this configuration, the position of the electricity user can be adjusted over a wide range in the lateral direction compared to the size of the three-dimensional structure and the solar panel.

When the multiple solar panels are deployed, a vent hole is provided between the edges where the hinges are provided.

This configuration reduces wind pressure on the solar panels.

The present invention has the advantages of being applicable to many uses, such as communication functions, monitoring functions, ventilation functions, cooling functions, and/or lighting, making the overall structure compact while maintaining the support strength and stability of the solar panel, and expanding the range of the position and functions of the electricity users.

The mobile power supply device 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 30.

In the present embodiment, the orientations or positional relationships of the terms "X", "Y", "Z", "up", "down", "left", "right", "front", "rear", etc. are based on the orientations or positional relationships shown in the drawings and are intended only to facilitate the description of the present embodiment and are not intended to limit the devices or elements to a particular orientation. The terms "first", "second", etc. are used for descriptive purposes only and do not indicate or imply any relative importance.

As shown in Figs. 1 to 13, the mobile power supply device 1 is characterized in that it comprises a wheel section 2, a three-dimensional structure section 4 provided on the wheel section 2 and having an attachment section 3, a solar panel 5 connected to the three-dimensional structure section 4 so that the elevation angle can be changed, an arm 6 having one end 6a and the other end 6b, the one end 6a of which is rotatably attached to the attachment section 3 and which can be in either a folded state or an unfolded state with respect to the attachment section 3, a lockable rotation mechanism 7 for locking the arm 6 in a predetermined position, and a power supply section 8 for storing electricity generated by the solar panel 5, and the other end 6b has a fixing section 9, which can be detachably connected to a support 10, which can be raised and lowered in the longitudinal direction L of the arm 6 as described below, an electricity user 11 can be fixed to the support 10, and electricity can be supplied to the electricity user 11 from the power supply section 8. In Figs. 1 and 2, "X" means left-right direction, "Y" means front-rear direction, and "Z" means height direction. Each component is explained in detail below.

As shown in FIG. 1, the wheel section 2 includes two pairs of wheels 21, mounting fixtures 22 for attaching the two pairs of wheels 21 to the four corners of the three-dimensional structure 4, and stoppers 23.

The mounting portion 3 has a generally U-shaped cross section in plan view, and includes a first member 3a and a second member 3b that extend in the front-rear direction of the three-dimensional structure 4 and are attached to the inclined tube 4b of the three-dimensional structure 4, a handle 3c that extends in the left-right direction and connects perpendicularly to the first member 3a and the second member 3b, and a pivot shaft 3d that rotatably connects the first member 3a and the arm 6. The first member 3a and the second member 3b each have a connecting portion 3e at their base end that connects to the two inclined tubes 4b. The connecting portion 3e may be integral with the other members of the first member 3a and the second member 3b, or may be separate. If separate, they are connected by a fastener or the like.

The three-dimensional structure 4 has a truss structure in side view and includes a bottom plate 4a, two pairs of symmetrical inclined tubes 4b that are connected to the bottom plate 4a and secure the two wheel sections 2, a horizontal tube 4c that connects the upper parts of the inclined tubes 4b, a connecting plate 4d that is a plate member in the fore-aft direction and connects the tops of the inclined tubes 4b, and a pair of bottom tubes 4e (see Figure 3) that extend in the fore-aft direction and connect the lower ends of the inclined tubes 4b and secure the two wheel sections 2, respectively.

The solar cell panel 5 is composed of a solar cell panel and a frame, with two solar cell panels connected vertically by multiple hinges 5a, and the two solar cell panels can be folded and unfolded around a rotation axis F. The locking mechanism 5b locks the solar cell panel 5 to the three-dimensional structure 4 when the mobile power supply device 1 is in the folded state. The connection area between the ends where the hinges 5a of the solar cell panel 5 are provided serves as a wind vent 5c, reducing wind pressure. To prevent damage, a flexible solar panel may be used instead of a general solar panel.

The arm 6 has one end 6a and the other end 6b, and the one end 6a is rotatably attached to the first member 3a and the second member 3b of the attachment part 3, and can be in either a folded state or an unfolded state with respect to the attachment part 3. A pair of arms 6 are provided on the left and right sides of the first member 3a and the second member 3b, respectively, and rotate outward with respect to the side surfaces of the first member 3a and the second member 3b.

The lockable pivot mechanism 7 connects one end 6a of the arm 6 to the first member 3a and the second member 3b via an axis so that the arm 6 can be pivoted laterally, and can lock the arm 6 in a desired position relative to the mounting part 3.

The power supply unit 8 is a portable power supply that stores electricity generated by the solar panel 5, and is fixed onto the bottom plate 4a so as to be located in the internal space 4f of the three-dimensional structure 4. The portable power supply includes, for example, a 100V AC power terminal, a communication terminal capable of supplying power (such as a USB terminal), and a 12V DC terminal.

The power supply unit 8 may be a portable power supply or may have other configurations. For example, the power supply unit 8 may have multiple built-in storage batteries.

The fixing part 9 is composed of a plate body that has a longitudinal direction and is fixed to the other end 6b of each of the pair of arms 6. The arms 6 and the support 10 are rotatably connected via the fixing part 9. The fixing part 9 may be a hollow member, such as a tubular member, in addition to a plate body.

The fixed part 9 and the support 10 can be detachably connected. The support 10 can be raised and lowered.

The support 10 includes a base 110, a magnetic body 121, a fixed support part 130, and a support column 140. The support 10 is attached to the surface of the fixed part 9 by the magnetic body 121. The support 10 of the present invention will be described in detail with reference to Figures 14 to 30.

As shown in FIG. 14, the support 10 has a base 110, magnetic bodies 121 and 122, a fixed support part 130, a support post 140, and a fixed support mechanism 150. The electric user 11 uses an LED lamp as a light source and is attached to the support post 140 via an attachment part 141. The support post 140 is supported by the fixed support part 130 so that it can be raised and lowered relative to the base 110, and is structured so that it can be raised and lowered in the direction in which the upper plate 111 extends (longitudinal direction). In addition, a handle 151 is attached to stop the support post 140 at any raised and lowered position. The base 110 has an upper plate 111 and a lower plate 112, and the magnetic bodies 121 and 122 are fixed to the lower surfaces of the ends of the upper plate 111 and the lower plate 112 via an elastic body 161.

The support 10 can be easily attached to the work vehicle 70 by attaching the steel plate portion of the work vehicle 70 to the magnetic bodies 121, 122 as an attachment target. The electricity user 11 is powered by the power source of the mobile power supply device 1. This allows the electricity user 11 to be used for work at a location away from the mobile power supply device 1, improving work efficiency. The support 10 can be easily transported and moved together with the mobile power supply device 1.

As shown in Figures 14 and 15, the base portion 110 has an upper plate 111 and a lower plate 112. The upper plate 111 is a substantially flat member extending in the longitudinal direction L. Both the upper plate 111 and the lower plate 112 are supported by a base shaft 113. This allows the upper plate 111 and the lower plate 112 to be connected in a rotatable manner.

A pair of magnetic bodies 121, 121 are fixed to the underside of the end of the upper plate 111 by bolts 125 with an elastic body 161 interposed therebetween. Also, a pair of magnetic bodies 122, 122 are fixed to the underside of the end of the lower plate 112 by bolts 125 with an elastic body 161 interposed therebetween.

The magnetic body 121 has a magnet 121a and an iron cap 121b. The upper end of the magnet 121a is covered by the cap 121b. This causes the magnetic force to concentrate on the exposed surface 121c where the magnet 121a is exposed. As a result, a stronger attraction force can be achieved compared to a magnet alone. Also, because the magnetic bodies are attracted mainly to the exposed surface 121c, even when the magnetic bodies are brought close to each other, they do not generate a large attraction or repulsion force between them. The magnet 121a is preferably made of a material with a strong attraction force, such as a neodymium magnet. The same applies to the magnetic body 122, so a description thereof will be omitted.

If the shape of the attracted object does not match the attracting surface of the magnetic bodies 121 and 122, only three of the four magnetic bodies will be attracted to the attracted object due to the difference in height. In other words, one magnetic body will be in a state where a gap is generated. The elastic body 161 can eliminate this gap by using its elasticity. It can also reduce the impact force when the fixed part 9 or the attracted object is impacted. As a result, all magnetic bodies can be attracted to the fixed part 9 or the attracted object, and a large attraction force can be obtained, and the attracted state can be maintained even when an impact is received. The thickness and elasticity value of the elastic body 161 can be appropriately determined taking into account the distance between the magnetic bodies 121 and 122, the expected unevenness of the attracted object, and the expected impact force.

It is preferable that the magnetic force of the magnetic material is such that, when the support 10 is attached to the object to be attached, the support 10 does not separate from the fixed part 9 or the object to be attached under wind speeds at which work can be performed. The magnetic force that can ensure a predetermined adhesive force can be determined appropriately taking into account the working conditions, etc.

The fixed support part 130 has a pair of standing plates 131a, 131b. The pair of standing plates 131a, 131b are provided to protrude from the upper plate 111, extending in the direction in which the upper plate 111 extends, i.e., in the longitudinal direction L. The support pillar 140 is inserted into the space provided in the pair of standing plates 131a, 131b, and is pivotally supported by both bolts 132, 152 so as to be rotatable. This allows the support pillar 140 to rise and fall relative to the longitudinal direction L of the arm 6.

When the support 140 is erected, a predetermined distance is ensured between the lower end of the support 140 and the upper plate 111. This ensures that the angular range of the support 140 is at least 180°.

The friction mechanism 135 is composed of a bolt 132 and an anti-loosening nut 132a. By rotating the bolt 132, a predetermined axial force is introduced into the bolt 132.

The vertical plate 131a and the web plate 142a located at the lower end of the outer support 142 are clamped between the bolt 132 and the anti-loosening nut 132a in a state where a certain frictional force is generated. In other words, a certain axial force is applied to the bolt 132. This frictional force suppresses sudden ups and downs of the support 140. It is preferable that the frictional force generated between the vertical plate 131a and the web plate 142a is set to such an extent that the support 140 can be rotated by hand and that the support 140 remains stationary in that state even if the hand is released.

The fixed support mechanism 150 is a mechanism that can fix the support 140 or make it rotatable by the operation of the handle 151. The standing plate 131b and the web plate 142b located at the lower end of the outer support 142 are clamped by a contact plate 153 attached to the end of the bolt 152 and a locking nut 152a. The handle 151 is rotatably connected to the end of the bolt 152. The handle 151 and the contact plate 153 are in contact with each other. When the handle 151 is in the upright state (as shown in FIG. 15), the contact plate 153 is pushed toward the standing plate 131b by the action of the cam 151a, and the locking nut 152a is pushed toward the web plate 142b. As a result, the fixed support mechanism 150 makes the web plate 142b and the standing plate 131b abut against each other with a larger pressure contact force. The large frictional force generated at this time fixes the support 140 in any undulating state. Also, by rotating the handle 151 and tilting it in a direction that is horizontal to the bolt 152, the support 140 becomes rotatable.

As shown in FIG. 16, the electric user 11 is attached to the upper end of the support 140 via the attachment portion 141. The support 140 has an outer support 142 and an inner support 143 that is inserted into the outer support 142. The inner support 143 is structured so that it can move in the direction in which the outer support 142 extends. The attachment portion 141 is attached to the upper end of the inner support 143. By appropriately selecting the attachment portion 141, an electric user other than a lighting lamp, such as a fan, can be attached to the support 10.

A fixing member 145 is attached to the upper end of the outer support 142. The fixing member 145 is used to rotate the lever portion 144 to hold the inner support 143 stationary at a predetermined position.

A stopper 146 is fixed to the lower end of the inner support 143. The stopper 146 is intended to prevent the inner support 143 from rising (moving away from the base 110). The stopper 146 comes into contact with the fixing member 145, thereby preventing the inner support 143 from rising.

As shown in FIG. 17, the outer support 142 is a rectangular tube, and the inner support 143 has corners 143a that contact the four inner corners of the outer support 142. In addition, grooves 143b are provided between adjacent corners 143a of the four corners.

The lever portion 144 has a clamp lever 144a and a lever bolt 144b that connects to the end of the clamp lever 144a. When the clamp lever 144a is rotated, the lever bolt 144b located in the groove 143b moves toward the clamp lever 144a. This movement causes the inner support 143 to move toward the clamp lever 144a. Further rotation brings the outer surface 143c of the inner support 143 into pressure contact with the inner surface 142c of the outer support 142. The frictional force generated at this time restricts the movement of the inner support 143, and it stops at a specified position (see Figure 18).

The support 10 can be used in various forms. For example, as shown in FIG. 19, the support 140 may be laid down and attached to the adsorption surface of the object to be attached in a position (first position) where the upper plate 111 and the lower plate 112 intersect, or as shown in FIG. 20, the support 140 may be attached to the fixing part 9 or the adsorption surface of the object to be attached in a position (second position) where the upper plate 111 and the lower plate 112 overlap. The support 140 may also be erected and attached to the adsorption surface in a position where the upper plate 111 and the lower plate 112 intersect. Furthermore, the inner support 143 may be extended to a predetermined height for use.

We will now explain modified examples of the support 10. As the modified examples have similar configurations to the embodiment, we will mainly explain the different configurations. Configurations that are similar to the embodiment are given the same reference numerals, and for different configurations, numbers in the 200s are given for Modifications 1 and 2, and numbers in the 300s are given for Modification 3.

<Support 10 Modification 1>
25(a) and (b), the base 210 has an upper plate 211 and a first plate 212. Base shafts 213 are provided at both ends of the upper plate 211 and axially support both the upper plate 211 and the first plate 212. This allows the upper plate 211 and the first plate 212 to be rotatably connected.

The magnetic bodies 221 and 222 are fixed to the underside of both ends of the first plate 212 with the elastic body 261 interposed between them. The magnetic body 221 is located directly below the end of the upper plate 211, and the magnetic body 222 is located at the tip of the first plate 212.

Depending on the condition of the suction surface, the upper plate 211 and the first plate 212 may be arranged at a right angle as shown in FIG. 25(a), or may be arranged in a straight line as shown in FIG. 25(b).

<Support 10 Modification 2>
26(a) and (b), the base 210a has an upper plate 211, a first plate 212a, and a second plate 212b. Base shafts 213a are provided at both ends of the upper plate 211 and support the upper plate 211, the first plate 212a, and the second plate 212b. This allows the upper plate 211, the first plate 212a, and the second plate 212b to be rotatably connected.

The magnetic body 221a is fixed to the underside of the tip of the first plate 212a with the elastic body 261 interposed therebetween. The magnetic body 221b is fixed to the underside of the tip of the second plate 212b with the elastic body 261 interposed therebetween. In order to align the heights of the magnetic body 221a and the magnetic body 221b to form a flat attraction surface, it is preferable to attach an adjustment plate (not shown) between the magnetic body 221a and the first plate 212a.

Depending on the condition of the suction surface, the upper plate 211, the first plate 212a, and the second plate 212b may be arranged at the same angle as shown in FIG. 26(a), or may be arranged in a straight line as shown in FIG. 26(b).

<Support 10 Modification 3>
27 to 30, since the third modification has the same configuration as the embodiment, the different configuration will be mainly described. The same reference numerals are used for the same configuration as the embodiment, and the 300-series reference numerals are used for the different configuration.

As shown in FIG. 27, the support 10 variant 3 is configured to further include a stand 310 in addition to the support 10 of the embodiment. The stand 310 is intended to weaken the adhesive force acting on other steel metal members, etc., by adhering to the base portion 110. This makes it easier to store and manage the support 10 when not in use.

As shown in FIG. 28, the stand 310 has an upper stand plate 311 and a lower stand plate 312. The upper stand plate 311 and the lower stand plate 312 are supported by the stand shaft 313 with a predetermined gap between them. This allows the upper stand plate 311 and the lower stand plate 312 to be connected in a rotatable manner.

A pair of non-magnetic bodies 321, 321 and a pair of non-magnetic bodies 322, 322 are attached to the upper surface of the stand upper plate 311. When the stand upper plate 311 and the stand lower plate 312 overlap, i.e., when they are in the second position, the pair of non-magnetic bodies 321, 321 are connected to the stand upper plate 311 via the pair of non-magnetic bodies 322, 322, and the pair of non-magnetic bodies 321, 321 are connected to the stand upper plate 311 via the pair of non-magnetic bodies 322, 322.

A pair of non-magnetic bodies 322a, 322a is attached to the upper surface of the stand lower plate 312. As shown in FIG. 28, when the stand upper plate 311 and the stand lower plate 312 are in the first position where they overlap, the pair of non-magnetic bodies 322a, 322a contacts the lower surface of the stand upper plate 311 while being positioned directly below the pair of non-magnetic bodies 322, 322. The rotation of the stand upper plate 311 and the stand lower plate 312 is restricted, and the overlapping state is maintained. The non-magnetic body is preferably a material that is softer than steel material and does not become magnetic, such as a resin plate or a vinyl plate. This can prevent the support 10 from being magnetically attracted to other metal materials during transportation.

A pair of rubber feet 311a, 311a is attached to the underside of both ends of the stand upper plate 311, and a pair of rubber feet 312a, 312a is attached to the underside of both ends of the stand lower plate 312. When the stand upper plate 311 and the stand lower plate 312 cross and come into contact with each other, the lower ends of the rubber feet 311a, 312a are located on the same plane. Also, the upper ends of the non-magnetic materials 321, 322, and 322a are located on the same plane. As a result, when the stand upper plate 311 and the stand lower plate 312 cross, i.e., in the first position, the support 10 can be placed on a flat surface by connecting the base part 110 to the stand 310 (see Figures 29 and 30).

As shown in FIG. 6 etc., the electricity user 11 is attached to the upper end of the support 10 by the mounting fixture 12. If a lighting lamp is attached to the support 10 as the electricity user 11, it is possible to supply power from the power supply unit 8 to a balloon light that has been conventionally used for nighttime construction work, or an alternative energy-saving light with equivalent performance, further enhancing the lighting effect. By changing the positions of the arm 6 and the support 10, it is possible to simultaneously provide near and far lighting. As there is no engine noise, construction can be carried out quietly and does not disturb neighbors. It is easy to hear voices during construction meetings.

Although not shown in the figure, the electricity user 11 can of course be used as a wireless communication device in addition to lighting. For example, if a wireless router is installed as a wireless communication device, communication between a nearby mobile phone device and a remote location is possible. If the electricity user 11 is a Wi-Fi station, a Wi-Fi environment can be created by supplying power to it.

The electricity user 11 can be used as a surveillance camera or a surveillance camera with a night vision mode. By mounting a camera and a communication device, evidence can be preserved and theft can be quickly reported in the event of theft. By mounting a light and a camera as the electricity user 11 on the support 10, it is convenient for creating reports on nighttime construction work. The direction and position of the solar panel 5 can be adjusted according to the on-site conditions. Nighttime lighting can reduce the time and improve the efficiency of outdoor construction work, road construction work, etc.

By using a blower and a mist supplying machine together as the electricity user 11, the mist can be spread far away, making it an effective measure against heatstroke. Similarly, if the mist contains a disinfectant, it can sterilize the air as a measure against COVID-19. For example, a pair of fixing parts (not shown) are provided on the top of the power supply unit 8, and a tank (not shown) is attached to these fixing parts. The tank stores water or water containing a disinfectant, etc., and supplies it to a mist nozzle (not shown) etc. via a water pump, and a blower fan may be provided on the top of the mist nozzle. An environmental measuring device may be attached as the electricity user 11, and it can be used, for example, to observe landslides, etc.

The electricity user 11 can be selectively positioned at least in any one of a first position where it comes to rest at a position lower than the three-dimensional structure 4, a second position _P2 (see Figure 6, etc.) where it comes to rest at a position higher than the three-dimensional structure 4, and a third position P3 (see Figures 6, 10, etc.) where the arm 6 and the support 10 come to rest in an extended state in the left-right direction of the three-dimensional structure ₄ , by the raising and lowering of the support 10 and the rotation of the arm 6. Electricity generated by the solar panel 5 is stored in the power source unit 8, and electricity is supplied to the electricity user 11 from the storage battery.

The expansion mechanism 13 connects the frame sides of the upper solar panel 5 and the lower solar panel 5. The expansion mechanism 13 is, for example, a gas spring in the shape of a strap that contains gas.

One end of the telescopic device 14 is fixed to the connecting part 3e that connects the inclined tubes 4b, and the other end is fixed to the solar cell panel 5 on the lower side, and is located at the middle position in the height direction of the three-dimensional structure 4. As shown in Figures 4 and 5, the elevation angle of the solar cell panel 5 can be changed by extending and retracting the telescopic device 14. For example, this elevation angle can be varied in the range of 30° to 54°. An example of the telescopic device 14 is a flexible stay.

The power supply box 15 is electrically connected to the power supply unit 8 and has an output terminal (not shown), which is provided at the connection part 3e that connects the inclined tube 4b.

The first cover 16 covers the top, front, and back of the power supply unit 8, and the pair of second covers 17 covers the sides of the power supply unit 8. The second cover 17 has ventilation holes 17a and is attached to the bottom plate 4a via hinges 4g so that it can be raised and lowered (see Figure 3). The second cover 17 can be locked in the upright position by the locking part 18.

The operation and usage of the mobile power supply device 1 will be described. When transporting to a destination, the mobile power supply device 1 is set to the stored state shown in Figures 1 and 2. The mobile power supply device 1 is loaded onto a transport means such as a truck or container and moved to the destination. After that, after being installed at the desired location, as shown in Figures 4 and 5, the solar cell panel 5 is deployed in the appropriate position by displacing the extension mechanism 13 and extension tool 14 that connect the solar cell panel 5. As shown in Figures 6 and 7, the arm 6 is deployed 90° in the front-rear direction, and the support tool 10 and the electricity user 11 are attached to the other end 6b of the arm 6, and the height of the support tool 10 is adjusted appropriately. Electricity is supplied to the electricity user 11 while storing electricity in the solar cell panel 5.

Figures 8 and 9 show the case of nighttime work, in which the solar panel 5 is folded and positioned along the axial direction of the inclined tube 4b. Figures 10 and 11 show the case where the arm 6 is further rotated to an unfolded angle of 170°. Figures 12 and 13 show the case of nighttime work at this unfolded angle. When moving the mobile power supply device 1 to another location, the above procedure is reversed to change it to the stored state.

The usage of the support 10 will be described. In FIG. 21, the upper plate 111 and the lower plate 112 of the support 10 are set in the second position, and the support 10 is attached to the torii section 71 of the work vehicle 70. In this case, the work vehicle 70 is a truck for transporting materials, etc. In FIG. 22, the upper plate 111 and the lower plate 112 are set in the second position, and the support 10 is attached to the back section 72 of the work vehicle 70. In FIG. 23, the support 10 is attached to the body 73 of the work vehicle 70 via a magnetic sheet 75 in the first position. In FIG. 24, the support 10 is attached to the bonnet 81 of the work vehicle 80 via a magnetic sheet 75 in the first position. The magnetic sheet 75 is used to protect the painted surface.

The mobile power supply device 1 described above provides the following advantages:

The mobile power supply device 1 of the present invention can be used for many purposes, such as communication functions, monitoring functions, ventilation functions, cooling functions, and/or lighting, has the support strength and stability of the solar cell panel 5, and allows for easy adjustment of the elevation angle of the solar cell panel 5 while making the overall structure compact. It also allows for an expansion of the range of the position and function of the electricity user 11, and is easy to repair and maintain.

The mobile power supply device 1 can be loaded onto a truck and moved, so the electricity user 11 can be used over a wide geographic area while still loaded onto the truck. The position of the electricity user 11 can be easily changed freely by manipulating the arm 6 and the support 10.

The effects of the mobile power supply device 1 will now be described. The arm 6 can be in either a folded or unfolded state relative to the mounting part 3, expanding the range of movement of the arm 6. The support 10 can be removed from the fixed part 9, allowing the electricity user 11 to be used in a location separate from the mobile power supply device 1.

The support 10 can be easily attached to and detached from the fixed part 9, greatly improving workability.

This makes it easier to move the mobile power supply device 1 and rotate the arm 6.

When the mobile power supply device 1 is stored, the entire device can be made compact. The three-dimensional structure 4 allows for a simple structure that is resistant to wind pressure. The power supply unit 8 is connected to the bottom plate 4a, so the structure is simple and resistant to wind pressure. In particular, twisting or deformation of the three-dimensional structure 4 through the solar cell panel 5 due to wind pressure can be prevented. The wind vent 5c reduces the wind pressure acting on the solar cell panel 5.

The connecting portion 3e serves to reinforce the truss structure and to secure the power supply box 15, facilitating access to the power supply. The connecting portion 3e can also assist in changing the elevation angle.

By locking the second cover 17, the power supply unit 8 can be prevented from being stolen. Maintenance of the power supply unit 8 becomes easier.

Since multiple solar panels 5 are connected by hinges 5a so that they can be folded around the rotation axis F, the solar panels 5 can be easily folded, and the shadows of people, the arms 6, and the supports 10 are unlikely to be reflected on the light collecting surface of the solar panels 5. This has the advantage that there is no interference with the solar panels 5, such as the shadows of people, the arms 6, the supports 10, etc. blocking sunlight.

The extension tool 14 allows the elevation angle of the solar panel 5 to be changed with a simple configuration.

The arm 6 and support 10 allow the position of the electricity user 11 to be adjusted over a wide range in the vertical direction compared to the size of the three-dimensional structure 4 and the solar panel 5.

By transforming the arm 6 and support 10, it becomes easy to store, transport, fold, and change the angle.

Compared to the size of the three-dimensional structure 4 and the solar panel 5, the position of the electricity user 11 can be adjusted over a wide range in the horizontal direction.

This prevents the arm 6 and support 10 from interfering with the solar panel 5.

The support 10 can improve work efficiency by appropriately selecting the object to be attached. In addition, the range of application can be expanded by attaching electrical users other than lighting.

The convenience of the support device 10 will be described using an example of a situation in which it is used for nighttime work involving the movement of workers. In nighttime work, a floodlight equipped with a generator is generally used to ensure a specified level of illumination in the work area. A floodlight equipped with a generator is extremely heavy, and generally requires a vehicle with a crane to be used for unloading, setting up, and removing it. Furthermore, in mobile work involving the movement of the work site, situations may arise in which the specified level of illumination required for the work cannot be obtained due to the movement. If such a situation is anticipated, it is necessary to take measures such as moving a balloon floodlight equipped with a generator along with the movement of the work site, or installing a balloon floodlight in advance in a location where movement is anticipated.

When the support 10 is detached from the fixed part 9 and used while attached to the work vehicle 70, the light can be projected onto the work site area with the electricity user 11 attached to the support 10. The electricity required for the floodlight can be supplied directly from the work vehicle 70, for example, by using a cigarette power source. If the power supplied from the work vehicle 70 is not sufficient to light the floodlight, a portable power source can be installed on the work vehicle 70. The work vehicle 70 can also be moved when the work site is moved. In other words, when using the support 10, it is sufficient to attach the support 10 with the floodlight attached to the work vehicle 70, and there is no need to use a separate crane vehicle or the like to lift and unload the floodlight when installing or removing it.

The advantage of being able to use the electricity user 11 by detaching the support 10 from the fixed part 9 is that if the location where the electricity user 11 is used is not exposed to sunlight due to buildings, trees, etc., the mobile power supply device 1 can be placed in a solar-exposed area where electricity can be generated, and the electricity user 11 can be installed and operated at the desired location (with the power cable extended as necessary).

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, an aluminum frame is used extensively for the three-dimensional structure 4, etc., making it easier to transport and move.

The mobile power supply device of the present invention can be used for various construction works associated with civil engineering works, material storage areas, rest areas, events, camping, farms, heat stroke countermeasures, corona countermeasures, etc., and can utilize a wide range of functions such as lighting, monitoring, cooling, and ventilation. The mobile power supply device can be attached to various electrical users to improve work efficiency. In situations where magnetic materials or objects to be attracted are present, it can also be used as a mobile power supply device for use at home or for leisure. The industrial applicability of this invention is great.
