Summary of the Invention

Problems to be Solved by the Invention

[0004] However, it cannot be easily moved for temporary use, or quickly removed at night (for security reasons such as theft), requires complicated operations, is difficult to generate and store electricity while moving according to the sunlight amount situation, and charge the storage battery of other solar cells as needed, and it is difficult to generate and use electricity with the movement of the work location.

[0005] Therefore, the present invention aims to provide a system that can be easily moved for temporary use and quickly removed at night (for security reasons such as theft), generates and stores electricity while moving according to the amount of sunlight, charges the batteries of other solar cells as needed, and enables the generation and use of electricity when moving the work site. [Means for solving the problem]

[0006] In view of the above problems, the mobile power supply device of the present invention 1 comprises: a plurality of solar cells; a mounting frame having an angle changing mechanism that allows the plurality of solar cells to rotate around a rotation axis and change between a folded state and an unfolded state in order to change the elevation angle formed by the main surfaces of the plurality of solar cells; a first support column that supports one side of the plurality of solar cells; a second support column that supports the other side of the plurality of solar cells in a height-adjustable manner; and a horizontal member extending laterally that supports the first support column and the second support column, wherein the lower end of the first support column or the second support column is provided The device comprises a wheel, a handle provided on the first or second support column on the side where the wheel is not provided, a rotating member provided at the lower part of the first and second support columns, and a pair of legs providing an opening / closing and lifting mechanism for opening and closing the rotating member and sliding it in the inclined direction, wherein the rotation trajectory of the rotating member is provided at an inclination with respect to the direction of the horizontal member, and by expanding the rotating member, the end of the rotating member descends and touches the ground, and by closing the rotating member, the end rises and becomes ungrounded, the wheel touches the ground, and the plurality of solar panels can be moved.

[0007] It is preferable to lift the handle and move the vehicle on one wheel to facilitate movement. This improves the efficiency of moving to other work locations.

[0008] It is preferable that a mounting section for attaching a power storage device, which includes a battery and a housing member for the battery, is attached to the horizontal member. By attaching the power storage device to the horizontal member, the center of gravity of the mobile power supply device is stabilized, which is effective against bad weather and strong winds.

[0009] The mobile power supply device of the present invention 2 comprises a plurality of solar cells, a frame having an angle changing mechanism that allows the plurality of solar cells to rotate around a rotation axis to change the elevation angle formed by the main surfaces of each of the plurality of solar cells, a first support column that supports the frame, a second support column that supports the frame, and a horizontal member extending laterally that supports the first and second support columns, wherein the mobile power supply device comprises a wheel provided at a specific position on the horizontal member, a rotating member that rotates in a specific direction, and a pair of legs having an opening / closing / lifting mechanism that opens and closes the rotating member and slides it vertically relative to the first and second support columns, wherein the wheel becomes ungrounded when the legs are lowered and the end of the rotating member is grounded, and the wheel becomes grounded when the legs are raised and the legs become ungrounded.

[0010] Preferably, the mounting frame comprises a frame for fixing multiple solar panels, a first axis member positioned laterally and serving as the rotation axis for the multiple solar panels, and a second axis member provided parallel to the first axis member and to which the angle adjustment mechanism is attached, wherein the first axis member and the second axis member are fixed to the first and second support columns. This simplifies the mounting frame structure.

[0011] Preferably, the wheels are positioned at the center of the transverse member in the longitudinal direction, and the legs are positioned at both ends of the transverse member in the longitudinal direction. This ensures good balance and makes movement easier.

[0012] During movement, the first support column, second support column, cross members, and legs are not grounded, while the wheels are grounded. During storage, the legs are closed and grounded, while the wheels, first support column, second support column, and cross members are not grounded. When the solar panels are generating power, the legs are open and grounded, while the wheels, first support column, second support column, and cross members are not grounded. This makes it easy to move, store, and install the mobile power supply unit.

[0013] Preferably, the aforementioned multiple solar panels have a structure that allows their elevation angle to be changed from vertical to horizontal when stored. This allows them to be adapted to the sunlight conditions and environment of the installation location.

[0014] It is preferable to orient the multiple solar panels vertically so that their elevation angles can be changed simultaneously. This allows the elevation angles to be adjusted all at once while keeping the orientation of the solar panels aligned, and to be adapted to the sunlight conditions and environment of the installation site. [Effects of the Invention]

[0015] The mobile power supply device of the present invention can be easily moved for temporary use, removed immediately at night (for security reasons such as theft), generates and stores electricity while moving between work sites according to the amount of sunlight, and can charge other storage batteries such as solar cells as needed, thereby enabling the generation and use of electricity while moving between work sites.

[0017] A mobile power supply device 1 (hereinafter simply referred to as "power supply device 1") according to Embodiment 1 of the present invention will be described with reference to Figures 1 to 18. As shown in Figure 3, etc., the power supply device 1 comprises a solar cell panel 2 and a solar cell panel 3, a mounting frame 4 having an angle changing mechanism 4a (see Figures 11 and 12) that allows the solar cell panels 2 and 3 to rotate around a rotation axis to change the elevation angle formed by the main surfaces of the solar cell panels 2 and 3, thereby changing between a folded state and an unfolded state, a first support column 5 that supports one side of the solar cell panels 2 and 3, a second support column 6 that supports the other side of the solar cell panels 2 and 3 in a height-adjustable manner, and a horizontal member 7 that extends laterally and supports the first support column 5 and the second support column 6. The angle changing mechanism 4a is an expandable and contractible cylindrical member. As the angle changing mechanism 4a expands and contracts, the solar cell panels 2 and 3 open and close around the longitudinal axis of the mounting frame 4. The second support column 6 is equipped with an extension mechanism 6a that extends and retracts in the longitudinal direction. This is to change the height of the second support column 6.

[0018] Both ends of the horizontal member 7 are connected to the lower ends of the first support column 5 and the second support column 6. As shown in Figure 7(b), the horizontal member 7 has a series of grooves along its longitudinal direction: groove 7a on the top surface, groove 7b on the left side, groove 7c on the right side, and groove 7d on the bottom surface. In addition, the horizontal member 7 is fitted with a sliding fastener 13 for attaching a mobile energy storage device 201, as will be detailed in the application examples described later.

[0019] A pair of wheels 8 are provided at the lower end of the first support column 5, and a handle 9 is provided on the second support column 6 on the side without the wheels 8. The wheels 8 have a pair of tires and a rotation axis perpendicular to the horizontal member 7 that connects the tires. The lower parts of the first support column 5 and the second support column 6 each have legs 12 that provide a pair of left and right rotating members 10 and an opening / closing / lifting mechanism 11 (see Figure 4, etc.) that opens and closes the rotating members 10 while sliding them. As shown in Figure 5, etc., the opening / closing / lifting mechanism 11 includes a guide hole 11a and an inclined plate 11b that provides the guide hole 11a. Below the inclined plate 11b, the rotating members 10 rotate while sliding in the guide hole 11a, and the rotation trajectory of the rotating members 10 is inclined with respect to the horizontal direction. By expanding the rotating members 10 in the R direction, the end 10a of the rotating members 10 (see Figures 11 and 12) touches the ground, and the wheels 8 rise relatively in the Y direction and become off-ground. On the other hand, by closing the rotating member 10 inward in the R direction, the end portion 10a rises and is positioned adjacent to the horizontal member 7, so that it does not come into contact with the ground and does not interfere with work. At this time, the wheels 8 come into contact with the ground, allowing multiple solar panels 2 and 3 to be moved. This mechanism is made possible by the inclined trajectory of the tip of the end portion 10a.

[0020] As described above, with the legs 12 closed, lifting the handle 9 and moving the vehicle on one wheel 8 makes it easy to move the work area.

[0021] For detailed examples of solar panel 2, solar panel 3, mounting frame 4, etc., please refer to Patent Document 1. The mounting frame 4 has a frame structure.

[0022] Figures 8 to 17 show an application example in which a mobile battery 201 is attached to the mobile power supply device 1 of Embodiment 1 of the present invention. The horizontal member 7 is a member that connects to the lower parts of the first support column 5 and the second support column 6 and supports them. As shown in Figures 6 and 7, the horizontal member 7 is provided with a sliding fastener 13 for supporting the mobile battery storage device 201. The sliding fastener 13 is fitted into grooves 7a and 7d and has a structure that allows it to slide in the longitudinal direction of the horizontal member 7. This sliding fastener 13 is a support that supports the mobile battery storage device 201 from below and comprises a pair of sliders 14 that slide in the axial direction of the horizontal member 7, a fastener 15 (in this embodiment, a catch clip, which can be used to prevent theft using a padlock or the like) for attaching the mobile battery storage device 201 to a predetermined position, and a knob 16 for fixing the sliders 14 to the horizontal member 7. As shown in Figures 16 and 17, the mobile energy storage device 201 is attached to the horizontal member 7 and secured with the fastener 15. Then, the slider 14 is secured with the knob 16 to support the mobile energy storage device 201 from below. This allows the elevation angles of the solar panels 2 and 3 to be set, and the generated electricity to be stored in the mobile energy storage device 201. It also functions as a counterweight against wind pressure, etc., and together with the legs 12, prevents the power supply unit 1 from unexpectedly tipping over. The mobile energy storage device 201 can be removed from the horizontal member 7 by releasing the fastener 15.

[0023] In the application examples shown in Figures 8 to 17 above, the mobile energy storage device 201 was attached and fixed to the power supply unit 1. However, if the light reception conditions of solar panels 2 and 3 are poor, as shown in Figure 18, the energy storage efficiency can be improved by removing the power supply unit 1 from the mobile energy storage device 201 and moving the power supply unit 1 to a location with better light reception.

[0024] During transport, the power supply unit 1 can be moved by the wheels 8 when a worker lifts the handle 9 and pulls the handle 9.

[0025] Next, the configuration and operation of an example of applying the power supply unit 1 to an electrical user 401 (in this case, a security camera) will be explained along with its effects, with reference to Figure 18.

[0026] Figure 18 shows the power supply unit 1 and the mobile energy storage device 201 connected by wiring in a separated state, with the power generated by solar panels 2 and 3 stored in the mobile energy storage device 201. As shown in Figure 16(b), the mobile energy storage device 201 includes a battery 201a, a housing member 201b that covers and protects the battery 201a, and wheels 201c. This mobile energy storage device 201 can be connected to other solar panels or electrical users 401 (such as security cameras, but also lighting fixtures, monitoring devices, blowers, etc.) by wiring 301, and electricity can be supplied by transmitting power from the battery 201a of the mobile energy storage device 201 to the other electrical users 401.

[0027] As shown in Figure 18, the mobile energy storage device 201 is equipped with a work support 202 in addition to the configuration described above. The work support 202 has a base portion 211, a fixed support portion 212, a support column 213, and a mounting portion 214. A support column 215 extends upward from the mounting portion 214, for example, by a magnetic material and can be attached and detached via the mounting portion 214, and the support column 215 has an extendable structure. The electrical user 401 is fixed to the tip of the support column 215 by a mounting portion 216.

[0028] In this embodiment, a security camera is given as an example of the electrical device 401 attached to the work support 202, but it may also be any device that operates using electricity and can achieve a specific purpose, such as a lighting fixture, a blower, a mist generator, or a photographic device (surveillance camera, etc.).

[0029] The magnetic force of the magnetic material is preferably such that, when the support column 215 is attracted to the object to be attracted, the support column 215 does not separate from the object to be attracted under working wind speeds. The magnetic force that ensures a specific attraction force can be determined appropriately, taking into account working conditions, etc.

[0030] As described above, the work support device 202 can improve work efficiency by appropriately selecting the object to be attached. Furthermore, the scope of application of the present invention 1 can be expanded by attaching electrical utilities 401 other than security cameras.

[0031] The convenience of the work support device 202 will be explained using an example of its use in work that involves the movement of workers.

[0032] At work sites, it is common to use an electrical unit 401 equipped with a generator. The electrical unit 401 equipped with a generator is extremely heavy, and it is common to use a crane truck for unloading, installation, and removal. Furthermore, in mobile work that involves moving the work site, it is necessary to move the electrical unit 401 equipped with a generator along with the work site, or to install the electrical unit 401 in advance at a location where movement is anticipated.

[0033] On the other hand, in this embodiment, when using a work support 202 attached to the mobile energy storage device 201, the electrical unit 401 can be used in the work area simply by attaching it to the work support 202. Since it does not have a generator, it is lightweight, and there is no need for a crane truck or similar vehicle for unloading, installation, movement, and removal. In addition, the electricity required for the electrical unit 401 can be supplied directly from the work vehicle, for example, by using a cigarette lighter power supply. If the power supplied from the work vehicle is not sufficient for the use of the electrical unit 401, the power supply unit 1 or the battery 201a of the mobile energy storage device 201 can be used. Alternatively, the power supply unit 1 or the mobile energy storage device 201 can be moved when moving to a different work location. When using the mobile energy storage device 201, it is sufficient to attach the support column 215 to which the electrical utilization unit 401 is attached to the fixed support unit 212 via the attachment part 214, and there is no need to use a crane truck or the like separately for lifting and unloading during the installation and removal of the electrical utilization unit 401.

[0034] A mobile power supply device 101 (hereinafter simply referred to as power supply device 101) according to Embodiment 2 of the present invention will be described with reference to Figures 19 to 53. Descriptions of the configuration of Embodiment 2, which is common to Embodiment 1, will be omitted as appropriate, and the description will focus on the features of Embodiment 2. Numbers of common elements will be in the 100s, and corresponding numbers will be cited. The main differences between Embodiment 1 and Embodiment 2 are that the solar panels 2 and 3 have been changed from horizontal to vertical orientation and the number of panels has been increased, the solar panels have been arranged in parallel on one side, the position of the wheels 8 has been moved to the center, the angle changing mechanism 4a of the mounting frame 4 is provided on only one side, and the structure of the mounting frame 4 has been changed.

[0035] Figures 19 to 25 show the housing and storage state of the power supply unit 101. Figures 26 to 32 show the moving and transport state of the power supply unit 101. Figures 33 to 39 show the installed state (elevation angle 30°). Figures 40 to 46 show the installed state (elevation angle 0°). Figures 47 to 53 show the installed state (elevation angle of solar panels 102a to 102d adjusted with block 501).

[0036] As shown in Figure 25, the power supply unit 101 comprises a plurality of solar panels 102a to 102d arranged in parallel in the vertical direction, a mounting frame 104 that supports the solar panels 102a to 102d and has an angle changing mechanism 104a (see Figure 19, etc.) that allows the solar panels 102a to 102d to rotate around an axis in order to change the elevation angle formed by the main surfaces of the plurality of solar panels 102a to 102d, a first support column 105 that supports one side of the mounting frame 104, a second support column 106 that supports the other side of the mounting frame 104, and a horizontal member 107 that extends horizontally and supports the lower parts of the first support column 105 and the second support column 106. A wheel 108 is provided at the central part of the horizontal member 107.

[0037] The third support column 100 is erected from the position of the cross member 107 where the wheel 108 is located.

[0038] As shown in Figures 19 and 20, the power supply unit 101 is equipped with legs 112 on the first support column 105 and the second support column 106, each leg having a pair of rotating members 110 that rotate in a specific direction on a plane perpendicular to the horizontal member 107, and an opening / closing / lifting mechanism 111 that opens and closes the rotating members 110 and can change their position by moving up and down in the Y direction relative to the first support column 105 and the second support column 106. The legs 112, which have the rotating members 110 and the opening / closing / lifting mechanism 111, are attached to the first support column 105 and the second support column 106 so as to be able to move up and down (slide vertically) in the Y direction. By lowering the legs 112 in the Y direction, the ends 110a of the rotating members 110 touch the ground and the wheels 108 do not touch the ground. On the other hand, by raising the legs 112, the legs 112 do not touch the ground and the wheels 108 touch the ground.

[0039] As shown in Figure 22, the mounting frame 104 includes a frame 104b for fixing multiple solar panels 102a to 102d at intervals, a first axis member 104c arranged laterally, and a second axis member 104d provided parallel to the lower part of the first axis member 104c and connected to the horizontal member 104b-1 of the frame 104b by an angle changing mechanism 104a. The first axis member 104c is fixed to the upper ends of the first support column 105, the second support column 106, and the third support column 100, and the second axis member 104d is positioned below the first axis member 104c and is horizontally mounted and fixed to the first support column 105, the second support column 106, and the third support column 100. The multiple solar panels 102a to 102d rotate around the first axis member 104c as the axis of rotation.

[0040] The first shaft member 104c and the second shaft member 104d are reinforced by being connected to each other by reinforcing members 117 that are perpendicular to them.

[0041] The wheel 108 is positioned in the center of the longitudinal direction of the horizontal member 107, and legs 112 are provided at both ends of the longitudinal direction of the horizontal member 107. The wheel 108 is located at the bottom of the third support column 100.

[0042] As shown in Figures 19, 20, and 25, each leg portion 112 has a rotating member 110 and an opening / closing / lifting mechanism 111. As shown in Figures 20 and 25, the opening / closing / lifting mechanism 111 has a pair of first connecting plates 111a (one plate is sufficient, but two plates provide greater strength) that clamp and connect the upper parts of the first support column 105 and the rotating member 110 from both outer sides, and a pair of second connecting plates 111b (one plate is sufficient, but two plates provide greater strength) that clamp and connect the first support column 105 and the pair of rotating members 110 from both outer sides at a position below the first connecting plates 111a. Similarly, as shown in Figure 19, a pair of first connecting plates 111a and a pair of second connecting plates 111b are also provided that clamp and connect the second support column 106 and the rotating member 110 from both outer sides, and the above explanation applies accordingly.

[0043] The pair of first connecting plates 111a act as a link mechanism and have a left plate 111c and a right plate 111d positioned to the left and right of it (in this embodiment, the left plate 111c and the right plate 111d are integrally formed). These two plates 111c and 111d are rotatably connected to the first support column 105 and a pair of rotating members 110, respectively, by fastening members 111e, 111f, and 111g. The central fastening member 111f functions as a locking part, and when the screw is loosened, the leg portion 112 can slide up and down.

[0044] The pair of second connecting plates 111b act as a link mechanism and have a left plate 111h, a central plate 111i, and a right plate 111j positioned to the left and right of them. These three plates 111h, 111i, and the right plate 111j are rotatably connected to the first support column 105 and a pair of rotating members 110 by fastening members 111k, 111m, and 111o, respectively. The left plate 111h, the central plate 111i, and the right plate 111j are also connected by fastening members 111l and 111n. The central fastening member 111m functions as a locking part, and when the screw is loosened, the leg portion 112 can slide up and down.

[0045] As shown in Figures 19 to 25, when storing or keeping the vehicle, the rotating member 110 is closed (preferably slightly open so that it can stand on its own, as shown in the figure), the legs 112 are lowered to the ground, and the wheels 108 are not in contact with the ground.

[0046] During movement and transport, as shown in Figures 26 to 32, the rotating member 110 is closed and the legs 112 are raised so that the first support column 105, second support column 106, third support column 100, cross member 107 and legs 112 are not touching the ground, and the wheels 108 are touching the ground. When the cross member 107 is tilted, one of the legs 112 will touch the ground.

[0047] When installed horizontally with an elevation angle of 30° (when solar panels 102a to 102d are generating power), as shown in Figures 33 to 39, the rotating member 110 is opened, the legs 112 are lowered and grounded, and the first support column 105, second support column 106, third support column 100, horizontal member 107 and wheels 108 are left off-ground. The legs 112 can be opened to a specific width (in this case, the maximum width) and grounded, allowing for stability to prevent tipping. Multiple solar panels 102a to 102d each have an elevation angle of 30° in the longitudinal direction of each panel.

[0048] When installed horizontally with an elevation angle of 0° (when solar panels 102a to 102d are generating power), as shown in Figures 40 to 46, the rotating member 110 is opened, the legs 112 are lowered and grounded, and the first support column 105, second support column 106, third support column 100, horizontal member 107 and wheels 108 are left off-ground. The legs 112 can be opened to a specific width (in this case, the maximum width) and grounded, allowing for stability to prevent tipping. Multiple solar panels 102a to 102d have an elevation angle of 0° in the longitudinal direction of each panel.

[0049] When installed vertically with an elevation angle of 30° (when solar panels 102a to 102d are generating power), as shown in Figures 47 to 53, the rotating member 110 is opened, the legs 112 are lowered and grounded, and the first support column 105, second support column 106, third support column 100, horizontal member 107, and wheels 108 are left ungrounded. The legs 112 can be opened to a specific width (in this case, the maximum width) and grounded, allowing for stability to prevent tipping. In this case, as shown in Figures 49 and 50, the degree of downward sliding of the legs 112 is made greater on the second support column 106 side than on the first support column 105 side, and the legs 112 on the second support column 106 side are placed on the block 501, thereby tilting the solar panels 102a to 102d.

[0050] In other words, in the case of this installation (vertical orientation with an elevation angle of 30°), starting from a horizontal orientation with an elevation angle of 0°, the leg 112 on the first support column 105 side is slid down to lower the first support column 105 side, and two blocks 501 are used as a base. The leg 112 on the second support column 106 side is then placed on the blocks 501 and raised, thereby setting the longitudinal elevation angle of the solar panels 102a to 102d as a single unit to 30°. By adjusting the height of the blocks 501 and the sliding position of the leg 112, installation at other angles is also possible.

[0051] Thus, the multiple solar panels 102a to 102d have a structure that allows the elevation angle to be changed within a specific angular range, from the vertical state when stored to the horizontal state, even when placed vertically.

[0052] The effects of Embodiment 2 of the present invention, as described above, will now be explained. Since the wheel 108 is positioned in the center of the longitudinal direction of the cross member 107, and legs 112 are provided at both ends of the longitudinal direction of the cross member 107, the first support column 105, the second support column 106, the third support column 100, and the legs 112 can be left off-ground when the wheel 108 is in contact with the ground. Therefore, whether or not there are handles or hooks, the wheel 108 can be pulled to move to another work location.

[0053] When moving the power supply unit 101, it is well-balanced, can be supported with little force, and is easy to move.

[0054] Since the wheels 108 and the first support column 105, the second support column 106, and the third support column 100 can be in an ungrounded state, and the legs 112 can be in an open grounded state, the wheels 108 and the first support column 105, the second support column 106, and the third support column 100 do not get in the way, and the workability and stability of the support during power generation are increased.

[0055] During transport and storage, the legs 112 are almost closed and grounded, and when the solar panels 102a to 102d are generating electricity, the legs 112 can be opened to a specific width and grounded. This makes transport and storage easier, improves work efficiency, and enhances stability during power generation.

[0056] Solar panels 102a to 102d have a structure that allows the elevation angle to be changed from vertical to horizontal when stored, so they can be adapted to the sunlight conditions and environment of the installation location.

[0057] By arranging the solar panels 102a to 102d vertically, the elevation angle can be changed by altering the sliding position of either leg 112 or by installing block 501. This allows for simultaneous adjustment of the elevation angles of the solar panels 102a to 102d, and provides greater flexibility to adapt to the sunlight conditions and environment of the installation location. [Industrial applicability]

[0058] The power supply devices according to Invention 1 and 2 are easily movable, allowing them to be moved to a suitable location and generate electricity even in bad weather. By attaching various electrical components, work efficiency can be improved. Therefore, the industrial applicability of the present invention is great. [Explanation of symbols]
