JP-A-2017-67894

According to the observation device of Patent Document 1, depending on the height position of the object to be imaged, the pole may be extended to a long height position such as several tens of meters from the ground surface to image the object. May be required.

Therefore, when the pole is extended to such a height position for imaging, the pole may bend and swing depending on the diameter of the pole, so that the object can be stably observed at a fixed point. There is concern that it cannot be done. Especially in the sky of several tens of meters, such a concern is remarkable because it is easily affected by gusts and air currents.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a high-altitude observation device capable of stably performing fixed-point observation of an object at a high place.

The high-altitude observation device according to the present invention for achieving the above problems is a long rod-shaped body that is erected on an installation surface and is formed to be stretchable, and is connected to the rod-shaped body in a connected state. The buoyancy generating means that expands and contracts the rod-shaped body by buoyancy to position the rod-shaped body at a desired height position, and the height position of the rod-shaped body is fixed and held at the height position positioned by the buoyancy generating means. It is characterized by including a holding means for the buoyancy and an observation device attached to the buoyancy generating means.

According to this height observation device, the rod-shaped body is positioned at a desired height position by expanding and contracting the rod-shaped body by the buoyancy generating means according to the observation position of the object. At this height position, the height position of the rod-shaped body is fixed by the holding means.

In this way, the rod-shaped body is positioned at a desired height position, and the height position is fixed. Therefore, even if a gust or an air flow acts on the rod-shaped body, the rod-shaped body is bent. As a result, the rod-shaped body is suppressed from swinging. Therefore, fixed point observation of the object at a high place can be stably performed by the observation device.

According to this high-altitude observation device, the buoyancy generating means is a rotary wing machine that floats by the rotation of a plurality of rotary blades. If the buoyancy generating means is a rotary wing aircraft, the rod-shaped body can be easily expanded and contracted.

On the other hand, according to this high-altitude observation device, the buoyancy generating means is a gas balloon that floats by gas. If the buoyancy generating means is a gas balloon, the rod-shaped body can be expanded and contracted with a simple configuration.

Further, the rotary wing aircraft is characterized in that it is connected to the rod-shaped body so as to be always vertical to the installation surface. According to this, since the rotorcraft is connected to the rod-shaped body so that it always faces vertically with respect to the installation surface, even if the rod-shaped body swings, it is a stable target at almost a fixed point. You can observe things.

On the other hand, the holding means includes a reel rotatably formed at the center of the shaft, and is wound around the reel and pulled out from the reel with the extension of the rod-shaped body, and is wound around the reel with the contraction of the rod-shaped body. It is characterized in that it is a winding mechanism including a wire.

According to such a configuration, the height position of the rod-shaped body can be fixed by a reel formed rotatably as the center of the shaft and a winding mechanism having a simple configuration having a wire wound around the reel.

Moreover, the winding mechanism is characterized by including an urging means for constantly urging the reel in a direction in which the wire is wound on the reel. In this way, when the wire is wound on the reel, it is not necessary to wind the wire on the reel, and the wire can be easily wound on the reel, so that the rod-shaped body shrinks. It is easily realized.

On the other hand, the rod-shaped body includes an outer cylinder and a plurality of inner cylinders whose diameters are gradually smaller than those of the outer cylinders, and each inner cylinder gradually has the diameter of each inner cylinder. It is characterized in that it is sequentially arranged inside the outer cylinder so as to be small and formed in a hollow shape, and further, the wire of the take-up mechanism is a power supply line for supplying power to the rotary wing machine. , It is characterized in that it is inserted into the rod-shaped body formed in a hollow shape.

By forming the wire to be inserted into the hollow rod-shaped body in this way, the rod-shaped body can be smoothly expanded and contracted without bending.

The high-altitude observation device according to the present invention for achieving the above problems is a long rod-shaped body that is erected on an installation surface and formed to be stretchable, and is connected to and connected to the rod-shaped body. A rotorcraft that expands and contracts the rod-shaped body by the buoyancy generated by the rotation of a plurality of rotorcraft to position the rod-shaped body at a desired height position, and a rotorcraft that cooperates with the rotorcraft to obtain the rod-shaped body as desired. A gas balloon connected to the rod-shaped body positioned at a height position, and a holding means for fixing and holding the height position of the rod-shaped body at a height position positioned by the gas balloon and the rotorcraft. The rotorcraft is provided with an observation device attached to the rotorcraft, and the rod-shaped body and the rotorcraft are disconnected from each other, and the rotorcraft shifts to a flight state.

According to this height observation device, the height position of the rod-shaped body is fixed by the holding means at the height position positioned by the rotorcraft and the gas balloon. In this case, when the connection between the rod-shaped body and the rotary wing aircraft is released, the rotary wing aircraft can shift to the flight state.

Therefore, if the object to be observed moves or moves, the rotary wing aircraft can be moved to the flight state to track the movement or movement of the object.

At this time, since the rod-shaped body is fixed in a state where its height position is positioned by the gas balloon, the connection between the rotorcraft and the rod-shaped body is released, and the rotorcraft shifts to the flight state. However, the height position of the rod-shaped body is maintained.

After that, when the rotorcraft is reconnected to the rod-shaped body, the observation can be performed at the same height position as before the rotorcraft transitioned to the flight state. Therefore, fixed point observation of the object at a high place can be performed. It can be performed stably with an observation device.

According to the present invention, fixed point observation of an object at a high place can be stably performed.

FIG. 4 is a diagram illustrating an outline of a case where the pole 30 transitions from the accommodation state to the extension state. As shown in FIG. 4A, when the rotor 30 is in the accommodated state and the rotor aircraft 40 rises in the ascending direction indicated by the arrow line U due to the rotation of the plurality of rotary blades 40c, the outer cylindrical body 31 The inner first cylindrical body 32 is gradually pulled out from the inner side.

The rotorcraft 40 stops ascending at a height position where the inner first cylinder 32 is pulled out and the enlarged diameter portion 32e of the inner first cylinder 32 is locked to the reduced diameter portion 31d of the outer cylindrical body 31. When shifting to the hovering state, the pole 30 transitions to an extended state in which the inner first cylindrical body 32 is pulled out from the outer cylindrical body 31 and locked as shown in FIG. 4 (b) (first extended state). ..

At this time, the power supply line 26 wound around the reel 23 is pulled out from the reel 23 following the ascent of the rotary wing machine 40, and when the rotary wing machine 40 shifts to the hovering state, the take-up mechanism 22 is provided. The rollers 27c of the locking mechanism 27 are arranged between the locking portions 25, 25 adjacent to each other.

As a result, the rotation of the reel 23 is restricted, and the length of the power supply line 26 drawn from the reel 23 is maintained, so that the height position of the pole 30 is fixed and held in the first extended state. ..

On the other hand, when the rotary wing aircraft 40 further rises in the ascending direction U while the pole 30 is in the first extended state, the inner second cylindrical body 33 is gradually pulled out from the inner side of the inner first cylindrical body 32.

The rotorcraft 40 floats at a height position where the inner second cylinder 33 is pulled out and the enlarged diameter portion 33d of the inner second cylinder 33 is locked to the reduced diameter portion 32d of the inner first cylinder 32. When the pole 30 shifts to the hovering state in which the inner second cylinder 33 is pulled out from the inner first cylinder 32 and the outer cylinder 31 and locked as shown in FIG. 4 (c), the pole 30 is in an extended state. (Second extended state).

At this time, the power supply line 26 wound around the reel 23 is pulled out from the reel 23 following the ascent of the rotary wing machine 40, and when the rotary wing machine 40 shifts to the hovering state, the take-up mechanism 22 is provided. The rollers 27c of the locking mechanism 27 are arranged between the locking portions 25, 25 adjacent to each other.

As a result, the rotation of the reel 23 is restricted, and the length of the power supply line 26 drawn from the reel 23 is maintained, so that the height position of the pole 30 is fixed and held in the second extended state. ..

In this way, the height position of the pole 30 can be arbitrarily changed from the housed state of the pole 30 to the first extended state or the second extended state, so that the height position of the pole 30 can be arbitrarily changed according to the observation position of the object. The object can be imaged by the camera 50 by transitioning to the first extended state or the second extended state.

For example, when the height observation device 10 is arranged directly under the bridge and a specific part at a high place of the bridge is observed, the pole 30 is in the first extended state according to the height position of the specific part. Alternatively, the transition to the second extended state can be made, and the camera 50 can image a specific part.

Alternatively, when observing the traffic conditions on the road or the situation of attracting customers at the event venue from a high place, the pole 30 is in the first extended state or the first extended state or the first depending on the height position at which those conditions can be appropriately observed. 2 It is possible to shift to the extended state and image those situations with the camera 50.

FIG. 5 is a diagram illustrating an outline of a connecting portion between the pole 30 and the rotary wing aircraft 40. As shown in the figure, for example, when the pole 30 swings in the horizontal direction indicated by the arrow line H, the rotary wing machine 40 is formed so as to be displaceable in the two axes of the x-axis and the y-axis. Displaces in the x-axis direction via.

In this way, the rotary wing aircraft 40 is connected to the pole 30 via the gimbal 35, so that the rotary wing aircraft 40 follows the swing of the pole 30 so that the rotary wing aircraft 40 always faces vertically with respect to the installation surface E. Displaces in the direction of two axes.

FIG. 6 is a diagram illustrating an outline of a case where the pole 30 transitions from the extended state to the accommodated state. As shown in FIG. 6A, when the rotary wing aircraft 40 is slightly levitated in the ascending direction U while the pole 30 is in the second extended state, it is arranged between the locking portions 25 and 25 adjacent to each other. The roller 27c of the locking mechanism 27 is pulled out from between the locking portions 25, 25, and the restriction on the rotation of the reel 23 is released.

When the restriction on the rotation of the reel 23 is lifted, the power supply line 26 is wound around the reel 23 by the coil spring 24a that urges the reel 23 in the direction of winding the power supply line 26 around the reel 23. Will be done.

When the power supply line 26 is gradually wound around the reel 23, the rotorcraft 40 is steered so as to be slightly pulled up in the ascending direction U, and a drag force is applied to the urging force of the coil spring 24a to supply power. The winding speed of the wire 26 can be adjusted.

When the power supply line 26 is wound up and the length of the power supply line 26 pulled out from the reel 23 becomes a length corresponding to the first extended state of the pole 30, the diameter of the inner second cylindrical body 33 is expanded. The lock between the portion 33d and the reduced diameter portion 32d of the inner first cylinder 32 is released, and as shown in FIG. 6B, the inner second cylinder 33 is housed inside the inner first cylinder 32. NS.

At this time, when the rotary wing machine 40 is steered so as to be pulled up in the ascending direction U to exert a drag force against the urging force of the coil spring 24a to stop the winding of the power supply line 26 by the reel 23, the rotation wing machine 40 is locked. The roller 27c of the mechanism 27 is arranged between the locking portions 25, 25, the rotation of the reel 23 is restricted, and the length of the power supply line 26 drawn from the reel 23 is maintained.

As a result, the pole 30 contracts from the second extended state and transitions to the first extended state, and its height position is fixed and held in the first extended state.

On the other hand, when the pole 30 is changed from the second extended state to the accommodated state, the power supply line 26 is wound around the reel 23 without restricting the rotation of the reel 23 in the first extended state.

When the power supply line 26 is wound up and the length of the power supply line 26 pulled out from the reel 23 becomes a length corresponding to the accommodation state of the pole 30, the enlarged diameter portion 32e of the inner first cylinder 32 The lock between the outer cylinder 31 and the reduced diameter portion 31d of the outer cylinder 31 is released, and as shown in FIG. 6C, the inner second cylinder 33 and the inner first cylinder 32 are inside the outer cylinder 31. Be housed.

In this way, since the height position of the pole 30 can be arbitrarily changed from the second extended state of the pole 30 to the first extended state or the accommodation state, the observation position of the object has changed. In some cases, the object can be followed or the observation can be stopped.

According to the high-altitude observation device 10 of the present embodiment, the pole 30 can be transitioned to the first extended state or the second extended state by the rotary wing aircraft 40 depending on the observation position of the object.

When the pole 30 is positioned in the first extended state or the second extended state, the length of the power supply line 26 drawn from the reel 23 is maintained at this height position, and the height position of the pole 30 becomes the first. It is fixed and held in the 1-extended state or the 2nd extended state.

In this way, when the pole 30 is positioned at a desired height position such as the first extended state or the second extended state, the height position is fixed, so that a gust or an air flow acts on the pole 30. However, the occurrence of bending of the pole 30 is suppressed, and as a result, the pole 30 is suppressed from swinging. Therefore, the fixed point observation of the object at a high place can be stably performed by the camera 30.

In particular, in the present embodiment, the rotorcraft 40 can easily expand and contract the pole 30. Moreover, since the rotary wing aircraft 40 is displaced in the biaxial direction following the swing of the pole 30 so as to always face vertically with respect to the installation surface E, the pole 30 may swing. Even if there is, the object can be observed stably at almost a fixed point.

Further, in the present embodiment, a simple configuration including a reel 23 rotatably formed around the rotating shaft 23a and a power supply line 26 for supplying electric power to the rotorcraft 40 and being wound around the reel 23. The winding mechanism 22 of the above holds the length of the power supply line 26 drawn from the reel 23, and the height position of the pole 30 is fixed and held in the first extended state or the second extended state.

The reel 23 of the take-up mechanism 22 is constantly urged in the direction of winding the power supply line 26 around the reel 23 by the coil spring 24a built in the boss portion 24 of the reel 23.

Therefore, when winding the power supply line 26 to the reel 23, it is not necessary to wind the power supply line 26 around the reel 23, and the power supply line 26 can be easily wound to the reel 23. Therefore, the inner first cylinder 32 and the inner second cylinder 33 can be easily accommodated inside the outer cylinder 31 of the pole 30.

In the present embodiment, the power supply line 26 is inserted into the hollow pole 30, so that the pole 30 can be smoothly expanded and contracted without bending the pole 30. ..

In the present embodiment, the gas balloon 70 includes an air sac 70a into which a gas such as helium or hydrogen is press-fitted, and a shroud line 70b attached to the air sac 70a to connect the air sac 70a to a pole 30 as a main configuration. It floats by the gas press-fitted into 70a.

When the pole 30 is transitioned from the accommodation state to the first extension state by using the gas balloon 70, for example, the gas required for extending the pole 30 to the first extension state may be press-fitted into the air sac 70a. ..

On the other hand, when the pole 30 is transitioned from the accommodation state to the second extension state, the gas required for extending the pole 30 to the second extension state may be press-fitted into the air sac 70a.

On the other hand, when the pole 30 is contracted from the second extended state or the first extended state to the accommodated state, the reel 23 of the winding mechanism 22 may be manually rotated in the direction of winding the power supply line 26. good.

On the other hand, if the gas gradually leaks from the air sac 70a, the buoyancy of the gas balloon 70 decreases. 30 gradually contracts.

As described above, according to the high-altitude observation device 60 of the present embodiment, the expansion and contraction of the pole 30 can be realized by the gas balloon 70 having a simple configuration.
