[0066] The first arm 10 and the second arm 13 are rotatably connected via a connecting portion 11 .

[0067] The upper end of second arm 13 has fixture 131, which has a U-shaped cross section and a plurality of mounting holes 132 on its upper surface. Fixing parts 14, 15 are attached to fixture 131 via fasteners 134 and mounting holes 132, and electricity users 16, 17 are detachably attached to fixing parts 14, 15. Fixing parts 14, 15 have a shape and structure that are compatible with electricity users 16, 17.

[0068] The electric users 16 are surveillance cameras, and the electric user 16 on the right side is a surveillance camera with a night vision mode.

[0069] The operation and usage of the autonomous mobile power supply unit 1 will now be described. The autonomous mobile power supply unit 1 shown in Fig. 1 is loaded onto a transport means such as a truck or container using lifting devices 65 and 66 and moved to the destination. After being installed at the destination, as shown in Figs. 11 and 12, the solar cell panel 7 is deployed, the link 9 and the cylinder 103 are displaced, the spacing between the second rod 102 increases, and the connecting part 11 is moved to a position higher than the third pipe 64.

[0070] In the same manner as described above, the autonomous mobile power supply apparatus 1 in Fig. 1 is moved to the destination. As shown in Figs. 13 and 14, the link 9 and the cylinder 103 are displaced, the spacing between the second rods 102 increases, and the connecting parts 11 are moved to a state in which they are deployed to the left and right of the third tube 64. 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. Then, the solar panel 7 is deployed.

[0071] In the same manner as above, the autonomous mobile power supply apparatus 1 in Fig. 1 is moved to the destination. As shown in Fig. 15, the solar panel 7 is unfolded, the link 9 and the cylinder 103 are displaced, the spacing between the second rods 102 increases, and the connecting parts 11 are moved to a state below the third pipe 64 and unfolded 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 pipe 64 are different.

[0072] Although not shown in the figures, it goes without saying that lighting fixtures, wireless communication devices, etc. can also be used as the electricity users 16 and 17.

[0074] If lighting fixtures are attached to the second arm 13 as the electricity users 16, 17, the battery 3 can supply power to balloon lights that have traditionally been used for nighttime construction work, or 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, both near and far lighting can be achieved. As there is no engine noise, construction can be carried out quietly, without disturbing neighbors. Voices can be heard easily during construction meetings.

[0075] By using a blower and a mist supplier together as the electricity users 16 and 17, the mist can be dispersed over long distances, making it an effective measure against heatstroke. Similarly, by adding a disinfectant to the mist, it is possible to sterilize the air as a measure against COVID-19. It can also be used for environmental measurements, such as observing landslides. If the electricity users 16 and 17 are used as WiFi stations, a WiFi environment can be created by supplying power to them.

[0076] The autonomous mobile power supply device 1 described above provides the following effects.

[0078] The autonomous mobile power supply unit 1 can be loaded onto a truck and transported, so that the electricity users 16, 17 can be utilized over a wide geographical area while remaining loaded onto the truck. The positions of the electricity users 16, 17 can be easily changed freely by operating the first arm 10 and the second arm 13.

[0079] The structural unit 6 can realize a structure that is strong against wind pressure with a simple configuration. Since the power supply unit 4 is connected to the substrate 22, the structure is strong against wind pressure in addition to being simple. In particular, twisting and deformation of the structural unit 6 due to wind pressure through the solar cell panel 7 can be prevented.

[0080] Since the multiple solar cell panels 7 are connected by hinges 74 so that they can be folded around the folding axis F, the solar cell 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 cell panels 7. This has the advantage that there is no interference with the solar cell panels 7, such as the shadows of people or the first arm 10 or second arm 13 blocking sunlight.

[0081] The adjustable stay 73 allows the elevation angle of the solar cell panel 7 to be changed with a simple configuration.

[0082] The first rod 101, the second rod 102, and the link 9 allow for a combination of large and small position adjustments to be made to adjust the positions of the electricity utilizing bodies 16, 17.

[0083] The wind vents 76 can reduce the wind pressure acting on the solar cell panel 7.

[0084] Since the first arm 10 can have a buffering effect, the movement of the electricity utilizing bodies 16 and 17 becomes easier.

[0085] The positions of the electricity utilizing bodies 16 and 17 can be adjusted over a wide range in the vertical direction by the first arm 10 and the second arm 13, compared to the size of the structural part 6 and the solar cell panel 7.

[0086] By transforming the first arm 10 and the second arm 13, it becomes easy to store, carry, fold, and change the angle.

[0087] The electric users 16, 17 are fixed using the fixture 131, the mounting holes 132 of the fixing parts 14, 15, and the fasteners 134. This makes it easy to mount various types of electric users 16, 17, such as cameras, lighting fixtures, mobile phones, or fans.

[0088] Compared with the size of the structural part 6 and the solar cell panel 7, the positions of the electricity utilizing bodies 16 and 17 can be adjusted over a wide range in the lateral direction.

[0089] This can prevent the first arm 10 and the second arm 13 from interfering with the solar cell panel 7.

[0090] 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, two electricity users 16, 17 are installed, but three or more electricity users may be installed. Although the first arm 10 is attached to the third pipe 64, it may be attached to the other first pipes 61a, 61b, or the second pipe 62, or it may be attached to an additional attachment pipe. The electricity users 16, 17 may be detached from the fixed parts 14, 15 for use. [Industrial Applicability]
