[0050] A plurality of storage batteries 3 (see FIG. 15) (two in this example) are built into the power supply unit 4. Examples of the storage batteries 3 include lead-acid sealed batteries (deep cycle batteries), which do not require refilling with water and have a depth of discharge. Ordinary starter batteries cannot be used continuously without charging, and are therefore unsuitable for solar cells. Even if the voltage of a deep cycle battery becomes low, there is little deterioration of the battery, and it can be used deeply. After adjusting the voltage with a charge controller (charge / discharge controller), it is supplied to the storage battery 3 and a full charge is detected. The storage battery 3 may be constituted by a known lithium ion battery.

[0055] Two solar cell panels 7a, 7b are connected by hinges 74 so that they can be folded around a folding axis F, and the sides of the solar cell panels 7 are connected by a cylinder 75, which is parallel to the folding axis F and the axial direction of the first tubes 61a, 61b. The elevation angle of the solar cell panel 7 can be adjusted within a range of 30° to 54°. A wind vent 76 is provided in the connecting area between the ends of the solar cell panels 7 where the hinges 74 are provided, thereby reducing wind pressure. The cylinder 75 is, for example, a gas spring.

[0056] The solar cell panel 7 may be a flexible solar panel instead of a general solar panel to prevent damage.

[0057] As shown in Figures 6 to 10, the mounting fixture 8 has a plate material 84 with a front surface 81, a rear surface 82, and a side surface 83, and has a first fixing portion 85 and a second fixing portion 86 on the front surface 81. The rear surface 82 is provided with a first hinge 87 and a second hinge 88. The plate material 84 is detachably attached to the vertical portion 64a of the third tube 64. The plate material 84 may be solid or hollow.

[0058] 6 to 10, each first arm 10 has a first rod 101 and a second rod 102 arranged in a mutually parallel position, and the first rod 101 and the second rod 102 are connected to each other by a link 9, and the movement of the link 9 enables mutual displacement between a first position Q1 (see FIG. 5) where the first rod 101 and the second rod 102 are close to each other, and a second position Q2 (see FIGS. 13 and 15) where the first rod 101 and the second rod 102 are separated from each other. The bases of the first rod 101 and the second rod 102 are attached to the rear surface 82 via a first hinge 87 and a second hinge 88, respectively.

[0059] In the vertical position, the first arm 10 and the second arm 13 are 1.5 to 4 times the height of the structure 6. In the horizontal position, the first arm 10 and the second arm 13 are 1.5 to 4 times the width of the structure 6.

[0060] The first arm 10 has a cylinder 103 that connects the mounting fixture 8 to the first rod 101 or the second rod 102. The cylinder 103 is a gas spring.

[0061] The connecting portion 11 is composed of a pair of parallel plates having a longitudinal direction, which are axially attached to the first arm 10 and the second arm 13, clamping and fixing the second arm 13 on one side and axially attaching the first rod 101 and the second rod 102 on the other side, so that the positions of the first arm 10 and the second arm 13 can be displaced relative to each other.

[0062] The connecting portion 11 is connected to the first arm 10 by pins 11a and 11b, and is fixed to the second arm 13 by a screw 11c.

[0063] The connecting part 11 can be positioned at least in any of a first position P1 (see FIG. 1) where it comes to rest at a position lower than the structural part 6, a second position P2 (see FIG. 11) where it comes to rest at a position higher than the structural part 6, and a third position P3 (see FIG. 13) where it comes to rest with the first arm 10 and the second arm 13 advanced in the left-right direction of the structural part 6. Electricity generated by the solar panel 7 is stored in the storage battery 3, and electricity is supplied from the storage battery 3 to the electricity users 16, 17.

[0064] As shown in FIG. 5, the rotation mechanism 12 includes a lock 121 attached to the first fixed portion 85, and a swivel torque hinge 122 attached to the second fixed portion 86 and capable of horizontal rotation.

[0065] Since the rotation mechanism 12 has a swivel torque hinge 122, the electricity users 16 and 17 can be stopped temporarily at an appropriate position.

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

[0067] The upper end of the second arm 13 has a fixture 131 which has a U-shaped cross section and has a plurality of mounting holes 132 on its upper surface. The fixing parts 14, 15 are attached to the fixture 131 via fasteners 134 and mounting holes 132, and the electricity users 16, 17 are detachably attached to the fixing parts 14, 15. The fixing parts 14, 15 have a shape and structure compatible with the 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 device 1 will now be described. The autonomous mobile power supply device 1 shown in Fig. 1 is loaded onto a transport means such as a truck or container using hoisting devices 65, 66, and moved to a destination location. After that, after being installed at the destination location, as shown in Figs. 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 becomes larger, and the connecting part 11 is moved to a position higher than the third pipe 64.

[0070] 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. 13 and Fig. 14, the link 9 and the cylinder 103 are displaced, the interval between the second rod 102 becomes larger, and the connecting part 11 is moved to a state in which it is 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. After that, 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 a 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 to a state where it is deployed to the left and right below the third tube 64. As shown in Fig. 14, the angles of the left and right first arms 10 and second arms 13 with respect to the third tube 64 are different.

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

[0073] 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 lighting lamp and a camera as 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 site conditions. Nighttime lighting can reduce time and improve the efficiency of outdoor construction work, road construction work, etc.

[0074] If lighting lamps 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 improving the lighting effect. By changing the positions of the first arm 10 and the second arm 13, it is possible to simultaneously provide far- and near-field lighting. Since there is no engine noise, construction can be carried out quietly and does not disturb neighbors. Voices are easy to hear during construction meetings.

[0075] If the electricity users 16 and 17 are used in combination with a blower and a mist supplier, the mist can be spread far away, making it an effective measure against heatstroke. Similarly, if the mist contains a disinfectant, it can be used 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 advantages.

[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 simple and strong against wind pressure. In particular, twisting and deformation of the structural unit 6 through the solar cell panel 7 due to wind pressure can be prevented.

[0080] Since multiple solar cell panels 7 are connected by hinges 74 so as to be foldable around the folding axis F, the solar cell panels 7 can be easily folded, and the shadows of people and the first arm 10 and 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 shadow of a person, the first arm 10, the second arm 13, etc. 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 the positions of the electricity utilizing bodies 16, 17 to be adjusted by combining large and small position adjustments.

[0083] The wind pressure acting on the solar cell panel 7 can be reduced by the wind vent 76 .

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

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

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

[0087] The electricity 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 kinds of electricity 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, 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. The first arm 10 is attached to the third tube 64, but it may be attached to the other first tubes 61a, 61b, or the second tube 62, or it may be attached to an additional attachment tube. The electricity users 16, 17 may be separated from the fixed parts 14, 15 for use. [Industrial Applicability]
