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 autonomous 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 provide support strength and stability for solar panels, and the third objective is to be able to expand the range of the location and functions of electricity users.

The invention to solve the above problem is an autonomous mobile power supply device that includes a cart, a power supply unit that houses a storage battery, a structural unit provided on the cart, a solar panel that is movably connected to the structural unit, a control unit that controls the electricity generated by the solar panel and supplies it to the storage battery, an arm that has a mounting fixture for mounting to the structural unit, and a lock that rotates the mounting fixture and locks it in a predetermined position, and that stores the electricity generated by the solar panel in the storage battery and supplies electricity from the storage battery to the electricity user.

With this configuration, the first to third objectives can be achieved.

In the present invention, the arm has a first arm and a second arm, the first arm and/or the second arm has a link, the first arm and the second arm are connected via a connecting part, and an electric user can be fixed to the second arm.

This configuration allows for greater freedom in arm position.

The connecting portion can be positioned at least in any of the following positions: a first position where it comes to rest at a position lower than the structural portion; a second position where it comes to rest at a position higher than the structural portion; and a third position where it comes to rest with the arm extended in the left-right direction of the structural portion.

With this configuration, the connecting parts can be positioned over a wide range of areas on the structure, from top to bottom, front to back, left to right, and so on, allowing greater freedom in the positioning of the electrical user.

The upper end of the second arm has a U-shaped cross section and a fastener with multiple mounting holes on the upper surface.

This configuration makes it easy to install various types of electrical users, such as cameras, lighting fixtures, wireless communication devices including mobile phones, or fans.

The first arm has a first rod and a second rod that are arranged in a mutually parallel position, and the first rod and the first rod are connected to each other by a link, and the movement of the link allows the first rod and the first rod to be displaced between a first position where the first rod and the first rod are close to each other and a second position where the first rod and the first rod are separated from each other.

This configuration allows the position of the electricity user to be adjusted by combining large and small position adjustments.

When in the vertical position, the first and second arms are 1.5 to 4 times the height of the structural part.

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 structure and the solar panel.

When in a horizontal position, the first arm and the second arm are 1.5 to 4 times the width of the structural part.

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 structure and the solar panel.

The first arm has a cylinder that connects the mounting fixture to the first rod or the second rod.

This configuration allows the first arm to have a cushioning effect, making it easier to move the electrical user body.

The rotation mechanism has a torque hinge.

This configuration allows the electricity user to stop temporarily at an appropriate position.

The structural part is U-shaped and comprises a pair of parallel, vertical first tubes and a second tube that connects the upper parts of the first tubes at right angles.

This configuration allows for a simple structure that is resistant to wind pressure.

The front end of the solar panel is rotatably attached to the top of one of the first tubes, and the rear end of the solar panel is attached to the top of the other first tube via the flexible stay.

This configuration allows the elevation angle of the solar panel to be changed with a simple structure.

The solar panels are hinged so that they can be folded around a folding axis, and are connected to the panel by a cylinder, with the folding axis and the axial direction of the upper part of the first tube being parallel.

This configuration makes it easy to fold the solar panel, and shadows of people and the first and second arms are less likely to be reflected on the solar panel.

When the 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.

It has a base plate on which the wheels of the dolly are attached, and the power supply unit is connected to the base plate.

This configuration is simple and resistant to wind pressure. In particular, it can prevent twisting and deformation of the structure caused by wind pressure through the solar panel.

The electrical user unit 16 is a surveillance camera, and the electrical user unit 16 on the right side is a surveillance camera with a night vision mode.

The operation and usage of the autonomous mobile power supply device 1 will now be described. The autonomous mobile power supply device 1 shown in Figure 1 is loaded onto a transport vehicle such as a truck or container using lifting devices 65, 66, and moved to the destination. After that, after being installed at the destination, as shown in Figures 11 and 12, the solar panel 7 is deployed, the link 9 and the cylinder 103 are displaced, the gap between the second rod 102 increases, and the connecting part 11 is moved to a position higher than the third pipe 64.

As described above, the autonomous mobile power supply device 1 in Figure 1 is moved to the destination. As shown in Figures 13 and 14, the link 9 and cylinder 103 are displaced, the distance between the second rod 102 increases, and the connecting part 11 is moved to a state where it is deployed to the left and right of the third tube 64. As shown in Figure 14, the angles of the left and right first arms 10 and second arms 13 relative to the third tube 64 are different. The solar panel 7 is then deployed.

As described above, the autonomous mobile power supply device 1 in FIG. 1 is moved to the destination. As shown in FIG. 15, the solar panel 7 is deployed, the link 9 and the cylinder 103 are displaced, the distance between the second rod 102 increases, and the connecting part 11 is moved below the third tube 64 and deployed to the left and right. As shown in FIG. 14, the angles of the left and right first arms 10 and second arms 13 relative to the third tube 64 are different.

Although not shown in the figure, the electric users 16 and 17 can of course also be lighting, wireless communication devices, etc. For example, if a wireless router is installed as a wireless communication device, communication between nearby mobile phone devices and remote locations is possible.

In the case of a camera, a night vision mode can be used. By mounting a camera and a communication device, evidence can be preserved and rapid notification of theft, etc. can be made in the event of theft, etc. By mounting a light and a camera as the electricity users 16, 17 on the second arm 13, it is convenient for creating reports on nighttime construction work, etc. The direction and position of the solar panel 7 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.

If lighting fixtures are attached to the second arm 13 as the electricity users 16, 17, it is possible to supply power from the storage battery 3 to balloon lights that have been conventionally used for nighttime construction work, or to alternative energy-saving lights with equivalent performance, further enhancing the lighting effect. By changing the positions of the first arm 10 and the second arm 13, 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. Voices are easy to hear during construction meetings.

When electricity users 16 and 17 use a blower and a mist supplier in combination, the mist can be spread over long distances, 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. It can also be used for environmental measurements, such as observing landslides. If electricity users 16 and 17 are used as WiFi stations, a WiFi environment can be created by supplying power to them.

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

The autonomous mobile power supply device 1 of the present invention can be used for many purposes, such as communication, monitoring, ventilation, cooling, and/or lighting, has the support strength and stability of the solar cell panel 7, facilitates the adjustment of the elevation angle, vertical direction, and horizontal direction of the solar cell panel 7, can expand the range of the positions and functions of the electricity users 16 and 17, and is easy to repair and maintain.

The autonomous mobile power supply device 1 can be loaded onto a truck and moved, so the electricity users 16, 17 can be used over a wide geographic area while still loaded onto the truck. The positions of the electricity users 16, 17 can be easily changed freely by manipulating the first arm 10 and the second arm 13.

The structural unit 6 can realize a simple structure that is strong against wind pressure. The power supply unit 4 is connected to the substrate 22, so it is simple in structure and strong against wind pressure. In particular, it can prevent twisting and deformation of the structural unit 6 through the solar panel 7 due to wind pressure.

Since multiple solar panels 7 are connected by hinges 74 so that they can be folded around the folding axis F, the solar panels 7 can be easily folded, and the shadows of people or the first arm 10 or second arm 13 are unlikely to be cast on the light collecting surface of the solar panels 7. This has the advantage that there is no interference with the solar panels 7, such as the shadows of people or the first arm 10 or second arm 13 blocking sunlight.

The adjustable stay 73 allows the elevation angle of the solar panel 7 to be changed with a simple configuration.

The first rod 101, the second rod 102, and the link 9 allow for a combination of large and small position adjustments to adjust the positions of the electrical users 16 and 17.

The wind vents 76 reduce the wind pressure acting on the solar panel 7.

The first arm 10 can have a cushioning effect, making it easier to move the electrical users 16 and 17.

The first arm 10 and the second arm 13 allow the positions of the electricity users 16, 17 to be adjusted over a wide range in the vertical direction compared to the size of the structural part 6 and the solar panel 7.

By transforming the first arm 10 and the second arm 13, it becomes easy to store, transport, fold, and change the angle.
