Summary of the Invention

Problems to be Solved by the Invention

[0012] However, in the inventions of Patent Documents 1 to 9, since lighting, surveillance cameras, etc. are mainly used at fixed points, it is difficult to expand to other applications.

[0013] Although Patent Document 2 can fold the solar panel with a hinge, the support structure of the solar panel is fragile, vulnerable to wind pressure, and not suitable for civil engineering construction, etc.

[0014] In Patent Document 3, the support structure of the solar panel is fragile and not suitable for civil engineering construction, etc. Although the up-and-down adjustment and left-and-right orientation adjustment of the lighting lamp can be performed, these adjustments have to be carried out individually, the operation is cumbersome, and since the post is fixed to the bottom plate, the lighting range is limited.

[0015] In Patent Document 5, the support structure of the solar panel is fragile and not suitable for civil engineering construction. The lighting lamp has to individually perform the rotation in the vertical and horizontal directions, the height, and the inclination angle adjustment, the operation is cumbersome, and since the lower support pipe is fixed to the trolley, the lighting range is limited.

[0016] The first object of the mobile power supply device of the present invention is that it can be applied to many applications such as communication functions, monitoring functions, blowing functions, cooling functions, and / or lighting, etc. The second object is to make the overall structure compact while maintaining the support strength and stability of the solar panel. The third object is to expand the position of the electrical appliance and the range covered by its functions.

Means for Solving the Problems

[0017] The invention for solving the above problems includes a wheel part, a three-dimensional structure part provided on the wheel part and having a mounting part, a solar panel connected to the three-dimensional structure part so that the elevation angle can be changed, an arm having one end and the other end, the one end being rotatably attached to the mounting part, and the arm taking either a folded state or an expanded state with respect to the mounting part, a rotation mechanism with a lock for locking the arm at a predetermined position, a power supply part for storing the electricity generated by the solar panel, and the other end having a fixing part, the fixing part and a support being detachably connected, the support being capable of fixing an electrical appliance, and the electrical appliance being capable of being supplied with electricity from the power supply part. This is a mobile power supply device.

[0018] With this configuration, the arm can take either a folded state or an expanded state with respect to the mounting part, so the movement range of the arm is expanded. Since the support can be removed from the fixing part, the electrical appliance can be utilized at another location away from the mobile power supply.

[0019] The "power supply part" mentioned here is preferably a portable power supply. The portable power supply preferably includes, for example, a 100V AC power supply terminal, a USB terminal capable of supplying power, a 12V DC terminal, etc.

[0020] The "electrical appliance" mentioned here is something that achieves a predetermined purpose using electricity. Specifically, it is a lighting lamp, a mist generator, a blower (such as a fan), a video device (such as a surveillance camera), a wireless communication device, etc.

[0021] Examples of the mode of "the fixing part and the support being detachably connected" include a configuration that detaches by a magnetic body and a configuration that detaches by a fastener.

[0022] It is preferable that a magnetic body is provided at the base of the support and can be adsorbed to the fixing part which is the adsorbed body. With this configuration, the detachment of the support from the fixing part is easy, and the workability is greatly improved.

[0023] The mounting portion is U-shaped in plan view, and includes a first member, a second member that are attached to the three-dimensional structure portion in a predetermined direction, and a handle that connects the first member and the second member. A pair of left and right arms are provided on each of the first member and the second member, and it is preferable that the arms rotate outward with respect to the side surfaces of the first member and the second member. With this configuration, it becomes easy to move the mobile power supply device and rotate the arms.

[0024] The three-dimensional structure portion has a truss structure in side view, and includes a bottom portion, and symmetrical inclined portions connected to the bottom portion, and a lateral portion connecting the upper portions of the inclined portions. When in the stored state, the solar panel preferably removes the support and the electrical appliance from the fixing portion, drives a telescopic mechanism connecting the solar panel, slides the telescopic mechanism, folds the solar panel, and is arranged along the axial direction of the inclined portion of the truss structure. With this configuration, in the stored state of the mobile power supply device, the whole can be made compact. It is possible to prevent twisting and deformation of the three-dimensional structure portion via the solar panel due to wind pressure.

[0025] A power box that is electrically connected to the power supply unit and has output terminals is preferably provided on the first member and / or the second member. With this configuration, the connecting portion can serve as a role of reinforcing the truss structure and fixing the power box, and can facilitate access to the power supply.

[0026] One end of a telescopic member is connected to the first member and / or the second member, and the other end is connected to the solar panel, so that it is preferable that the elevation angle of the solar panel can be changed. With this configuration, the connecting portion can also serve as a role of assisting in changing the elevation angle.

[0027] The bottom portion preferably has a substrate for attaching the wheel portion, and the power supply unit is fixed on the substrate so as to be present in the internal space of the three-dimensional structure portion.

[0028] According to this configuration, on top of a simple structure, it is resistant to wind pressure. It can prevent torsion and deformation of the three-dimensional structure part through the solar panel due to wind pressure. The center of gravity is stabilized, and it becomes easier to attach the cover.

[0029] Preferably, it includes a first cover that covers the top surface, front surface, and back surface of the power supply unit, and a pair of second covers that cover the side surfaces of the power supply unit, and it is preferable that the second cover is attached to the bottom surface portion via a hinge so as to be able to fluctuate. With this configuration, theft of the power supply unit can be prevented by locking the second cover. Maintenance of the portable power supply becomes easier.

[0030] Preferably, the support tool includes a column having a mounting portion for mounting the electrical appliance that operates by receiving electrical supply, a fixed support portion that supports the column so as to be able to fluctuate and can maintain the fluctuating position of the column, a pedestal portion that supports the column via the fixed support portion, and at least a pair of magnetic bodies that are fixed to the lower surface of the pedestal portion and adsorb the object to be adsorbed, and the magnetic bodies are detached from the fixed portion and adsorbed to the object to be adsorbed.

[0031] According to this configuration, by adsorbing the magnetic bodies to the fixed portion, the electrical appliance can be easily installed in a stable state. By detaching the magnetic bodies from the fixed portion, the electrical appliance can be utilized at a distant location. Transportation and movement of the support tool and the electrical appliance itself are easy. By using the object to be adsorbed as the base portion required for stable placement, weight reduction is possible.

[0032] Preferably, the pedestal portion has an upper plate, and the magnetic bodies are fixed to the lower surface of the upper plate.

[0033] According to this configuration, since the magnetic bodies are fixed to the lower surface of the upper plate, the column can efficiently resist external forces acting in a predetermined direction (the direction in which the pair of magnetic bodies are arranged).

[0034] Preferably, the pedestal portion has a lower plate rotatably connected to the upper plate, the magnetic body is fixed to the lower surface of the lower plate, and the upper plate and the lower plate intersect at a first position, and the upper plate and the lower plate overlap or can take a second position where the longitudinal directions are aligned in the same direction.

[0035] According to this configuration, since the pedestal portion can take a first position where the upper plate and the lower plate intersect and a second position where the upper plate and the lower plate overlap or the longitudinal directions are aligned in the same direction, considering the shape of the fixing portion, it is possible to appropriately resist the external force acting on the support column as appropriate.

[0036] Preferably, the support tool includes a stand that adsorbs the pedestal Part The stand has a stand upper plate and a stand lower plate rotatably connected to the stand upper plate, and can take a first position where the stand upper plate and the stand lower plate intersect, and a second position where the stand upper plate and the stand lower plate overlap or the longitudinal directions are aligned in the same direction.

[0037] According to this configuration, by adsorbing the pedestal and the stand in the state of being located at the first position, the working support tool can be stably installed on the installation surface. Further, by adsorbing the pedestal and the stand in the state of being located at the second position, the shape can be made compact.

[0038] Preferably, the support column is characterized by undulating in the longitudinal direction.

[0039] According to this configuration, since the support column can be placed in a state of being laid down in the longitudinal direction, the overall shape can be made compact. Thereby, storage becomes easy and transportation efficiency is improved.

[0040] The electrical appliance can be arranged at any of a first position where it stands still at a position lower than at least the three-dimensional structure portion, a second position where it stands still at a position higher than the three-dimensional structure portion, and a third position where the arm extends in the left-right direction of the three-dimensional structure portion.

[0041] According to this configuration, since the electrical appliance can be located in a wide range above and below, front and back, and left and right of the three-dimensional structure portion, the degree of freedom in the position of the electrical appliance is increased.

[0042] In the vertical state, the electrical appliance is preferably 1.5 times to 4 times the height of the three-dimensional structure portion.

[0043] According to this configuration, compared with the size of the three-dimensional structure portion and the solar cell panel, the position of the electrical appliance can be adjusted in a wide range in the vertical direction.

[0044] The arm is 0.7 times to 2 times the depth of the three-dimensional structure portion in the front-back direction.

[0045] According to this configuration, compared with the size of the three-dimensional structure portion and the solar cell panel, the position of the electrical appliance can be adjusted in a wide range in the horizontal direction.

[0046] In a state where a plurality of solar cell panels are deployed, a ventilation hole is provided between the end edges provided with the hinge.

[0047] According to this configuration, the wind pressure applied to the solar panel can be reduced.

[0048] According to the present invention, it can be applied to many uses such as communication functions, monitoring functions, blowing functions, cooling functions, and / or lighting. While maintaining the support strength and stability of the solar cell panel, the overall structure is made compact, and the position and function range of the electrical appliance can be expanded.

Embodiments for Carrying Out the Invention

[0050] The mobile power supply device 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 30.

[0051] In the present embodiment, the orientation or positional relationship of terms such as "X", "Y", "Z", "up", "down", "left", "right", "front", and "rear" is based on the orientation or positional relationship shown in the drawings, and is only for facilitating the description of the present embodiment, and does not limit that the device or element has a specific orientation. Terms such as "first" and "second" are used only for the purpose of description and do not indicate or imply relative importance.

[0052] As shown in FIGS. 1 to 13, the mobile power supply device 1 includes a wheel portion 2, a three-dimensional structure portion 4 provided on the wheel portion 2 and having a mounting portion 3, a solar panel 5 connected to the three-dimensional structure portion 4 so that the elevation angle can be changed, an arm 6 having one end portion 6a and the other end portion 6b, the one end portion 6a being rotatably attached to the mounting portion 3, and the arm 6 taking either a folded state or an expanded state with respect to the mounting portion 3, a rotation mechanism 7 with a lock for locking the arm 6 at a predetermined position, and a power supply portion 8 for storing electricity generated by the solar panel 5. The other end portion 6b has a fixing portion 9, the fixing portion 9 and the support 10 can be detachably connected, the support 10 can be raised and lowered with respect to the longitudinal direction L of the arm 6 as will be described later, an electrical appliance 11 can be fixed to the support 10, and electricity can be supplied from the power supply portion 8 to the electrical appliance 11. In FIGS. 1 and 2, "X" means the left-right direction, "Y" means the front-rear direction, and "Z" means the height direction. Hereinafter, each component will be described in detail.

[0053] As shown in FIG. 1, the wheel portion 2 includes two pairs of wheels 21, a fixture 22 for attaching the two pairs of wheels 21 to the four corners of the three-dimensional structure portion 4, and a stopper 23.

[0054] The mounting portion 3 has a substantially U-shaped cross section in plan view, extends in the front-rear direction of the three-dimensional structure portion 4, and includes a first member 3a, a second member 3b attached to the inclined pipe 4b of the three-dimensional structure portion 4, a handle 3c extending in the left-right direction and orthogonally connected to the first member 3a and the second member 3b, and a rotation shaft 3d rotatably connecting the first member 3a and the arm 6. The first member 3a and the second member 3b each have a connecting portion 3e connected to the two inclined pipes 4b at their base ends. The connecting portion 3e may be integral with or separate from the other members of the first member 3a and the second member 3b. In the case of being separate, they are connected by a fastening tool or the like.

[0055] The three-dimensional structure part 4 has a truss structure in side view, and includes a bottom plate 4a, a pair of symmetrical inclined pipes 4b that are connected to the bottom plate 4a and fix the two wheel parts 2, a horizontal pipe 4c that connects the upper parts of the inclined pipes 4b, a connecting plate 4d which is a plate member in the front-rear direction and connects the top parts of the inclined pipes 4b, and a pair of bottom pipes 4e (see Fig. 3) that extend in the front-rear direction and connect the lower ends of the inclined pipes 4b and fix the two wheel parts 2 respectively.

[0056] The solar panel 5 is composed of a solar panel and a frame. Two solar panels are connected by a plurality of hinges 5a in the vertical direction, and the two solar panels can be folded and unfolded around the rotation axis F. The locking mechanism 5b locks the solar panel 5 to the three-dimensional structure part 4 when the mobile power device 1 is in the folded state. The connection area between the end sides provided with the hinges 5a of the solar panel 5 forms a ventilation hole 5c, which is a structure for reducing wind pressure. For damage prevention, a flexible solar panel may be used instead of a general solar panel.

[0057] The arm 6 has one end 6a and the other end 6b. One end 6a is rotatably attached to the first member 3a and the second member 3b of the attachment part 3, and can be in either a folded state or an expanded state with respect to the attachment part 3. A pair of left and right arms 6 are provided on the first member 3a and the second member 3b respectively, and rotate outward with respect to the side surfaces of the first member 3a and the second member 3b.

[0058] The rotation mechanism 7 with a lock laterally rotatably connects one end 6a of the arm 6 to the first member 3a and the second member 3b with a shaft, and can lock the arm 6 at a desired position with respect to the attachment part 3.

[0059] The power supply part 8 is a portable power supply that stores the electricity generated by the solar panel 5, and is fixed on the bottom plate 4a so as to be in the internal space 4f of the three-dimensional structure part 4. The portable power supply is provided with, for example, a 100V AC power supply terminal, a communication terminal (such as a USB terminal) capable of supplying power, and a 12V DC terminal.

[0060] In addition to a portable power source, the power supply unit 8 can have other configurations. For example, a plurality of storage batteries may be built into the power supply unit 8.

[0061] The fixing part 9 is composed of a plate body fixed to the other end parts 6b of a pair of arms 6 having a longitudinal direction. The arm 6 and the support 10 are rotatably connected via the fixing part 9. The fixing part 9 may be a hollow member, for example, a tubular member, etc., in addition to the plate body.

[0062] The fixing part 9 and the support 10 can be detachably connected. The support 10 can be raised and lowered.

[0063] The support 10 includes a pedestal part 110, a magnetic body 121, a fixed support part 130, and a support column 140. The support 10 is provided so as to be adsorbable to the surface of the fixing part 9 by the magnetic body 121. With reference to FIGS. 14 to 30, the support 10 of the present invention will be described in detail.

[0064] As shown in FIG. 14, the support 10 has a pedestal part 110, magnetic bodies 121, 122, a fixed support part 130, a support column 140, and a fixed support mechanism 150. The electrical appliance 11 uses an LED lamp as a light source and is attached to the support column 140 via an attachment part 141. The support column 140 is supported so as to be able to be raised and lowered with respect to the pedestal part 110 via the fixed support part 130, and has a structure that can be raised and lowered in the direction (longitudinal direction) in which the upper plate 111 extends. Also, a handle 151 for stationary the support column 140 at an arbitrary raised and lowered position is attached. The pedestal part 110 has an upper plate 111 and a lower plate 112, and the magnetic bodies 121, 122 are fixed to the lower surfaces of the ends of the upper plate 111 and the lower plate 112 via elastic bodies 161.

[0065] By adsorbing the steel plate portion of the work vehicle 70 to the magnetic bodies 121 and 122, the support tool 10 can be easily attached to the work vehicle 70. The electric appliance 11 operates with the power supply of the mobile power device 1. Thereby, since the electric appliance 11 can be used for work at a location away from the mobile power device 1, the work efficiency can be improved. Note that the support tool 10 can be easily transported and moved together with the mobile power device 1.

[0066] As shown in FIGS. 14 and 15, the pedestal portion 110 has an upper plate 111 and a lower plate 112. The upper plate 111 is a substantially flat plate member extending in the longitudinal direction L. Both the upper plate 111 and the lower plate 112 are pivotally supported by a pedestal shaft 113. Thereby, the upper plate 111 and the lower plate 112 are rotatably connected.

[0067] A pair of magnetic bodies 121, 121 are fixed to the lower surface of the end portion of the upper plate 111 by bolts 125 with an elastic body 161 interposed therebetween. Also, a pair of magnetic bodies 122, 122 are fixed to the lower surface of the end portion of the lower plate 112 by bolts 125 with an elastic body 161 interposed therebetween.

[0068] The magnetic body 121 has a magnet 121a and an iron cap 121b. The upper end portion of the magnet 121a is covered with the cap 121b. Thereby, the magnetic force is concentrated on the exposed surface 121c where the magnet 121a is exposed. As a result, a stronger adsorption force can be realized compared to a single magnet. Also, since adsorption mainly occurs on the exposed surface 121c, even when the magnetic bodies are brought close to each other, large adsorption forces and repulsive forces are not generated between the magnetic bodies. The magnet 121a is preferably a material having a strong adsorption force, for example, a neodymium magnet. The same applies to the magnetic body 122, so the description is omitted.

[0069] When the shape of the object to be adsorbed does not match the adsorption surfaces of the magnetic bodies 121 and 122, only 3 out of the 4 magnetic bodies are adsorbed to the object to be adsorbed due to the height difference. That is, one magnetic body is in a state where a gap is generated. The elastic body 161 can eliminate this gap by utilizing its elasticity. In addition, when the fixing part 9 or the object to be adsorbed is subjected to an impact, the impact force can be reduced. As a result, all the magnetic bodies can be adsorbed to the fixing part 9 or the object to be adsorbed, and a large adsorption force can be obtained. Moreover, even when an impact is received, the adsorption state can be maintained. The thickness and elastic value of the elastic body 161 may be appropriately determined in consideration of the distance between the magnetic bodies 121 and 122, the assumed unevenness of the object to be adsorbed, and the assumed impact force.

[0070] When the magnetic force of the magnetic body adsorbs the support 10 to the object to be adsorbed, it is preferable that the magnetic force has an adsorption force that prevents the support 10 from separating from the fixing part 9 or the object to be adsorbed under a workable wind speed. The magnetic force that can ensure a predetermined adsorption force may be appropriately determined in consideration of working conditions and the like.

[0071] The fixed support part 130 has a pair of standing plates 131a and 131b. The pair of standing plates 131a and 131b are provided so as to project from the upper plate 111 in a state of extending in the direction in which the upper plate 111 extends, that is, the longitudinal direction L. The support column 140 is inserted into the space provided between the pair of standing plates 131a and 131b and is rotatably supported by both the bolts 132 and 152. Thereby, the support column 140 can rise and fall with respect to the longitudinal direction L of the arm 6.

[0072] When the support column 140 is erected, a predetermined interval is ensured between the lower end of the support column 140 and the upper plate 111. Thereby, at least 180° of the angle range in which the support column 140 rises and falls is ensured.

[0073] The friction mechanism 135 is composed of a bolt 132 and a lock nut 132a. By rotating the bolt 132, a predetermined axial force is introduced into the bolt 132.

[0074] The standing plate 131a and the web 142a located at the lower end of the outer support column 142 are clamped by the bolt 132 and the locknut 132a in a state where a predetermined frictional force is generated. That is, a predetermined axial force is introduced into the bolt 132. The sudden undulating displacement of the support column 140 is suppressed by this frictional force. The frictional force generated between the standing plate 131a and the web 142a is preferably set such that the support column 140 can be rotated by hand and, even when the hand is released, the support column 140 remains stationary in that state.

[0075] The fixed support mechanism 150 is a mechanism that can fix the support column 140 or make it rotatable by the operation of the handle 151. The standing plate 131b and the web 142b located at the lower end of the outer support column 142 are clamped by the contact plate 153 attached to the end of the bolt 152 and the locknut 152a. The handle 151 is rotatably connected to the end of the bolt 152. Also, the handle 151 and the contact plate 153 are in contact with each other. When the handle 151 is in the upright state (the state shown in FIG. 15), the contact plate 153 is pushed in the direction of the standing plate 131b and the locknut 152a is pushed in the direction of the web 142b by the action of the cam 151a. As a result, the fixed support mechanism 150 causes the web 142b and the standing plate 131b to abut against each other with a greater contact pressure. The support column 140 is fixed in an arbitrary undulating state by the large frictional force generated at this time. Also, by rotating the handle 151 and tilting it in a direction parallel to the bolt 152, the support column 140 can be made rotatable.

[0076] As shown in FIG. 16, the electrical appliance 11 is attached to the upper end of the support column 140 via the attachment portion 141. The support column 140 has an outer support column 142 and an inner support column 143 inserted into the outer support column 142. The inner support column 143 is structured to be movable in the direction in which the outer support column 142 extends. The attachment portion 141 is attached to the upper end of the inner support column 143. By appropriately selecting the attachment portion 141, electrical appliances other than the lighting lamp, such as a blower, can be attached to the support 10.

[0077] A fixing member 145 is attached to the upper end of the outer support column 142. The fixing member 145 is for stationary the inner support column 143 at a predetermined position by rotating the lever portion 144.

[0078] A stopper 146 is fixed to the lower end of the inner support column 143. The stopper 146 is for suppressing the upward movement (movement in the direction away from the pedestal portion 110) of the inner support column 143. When the stopper 146 comes into contact with the fixing member 145, the upward movement of the inner support column 143 is suppressed.

[0079] As shown in FIG. 17, the outer support column 142 is a square tube, and the inner support column 143 has corner portions 143a that contact the four inner corners of the outer support column 142. Further, grooves 143b are provided between adjacent corner portions 143a among the four corners.

[0080] The lever portion 144 has a clamp lever 144a and a lever bolt 144b connected to an end of the clamp lever 144a. When the clamp lever 144a is rotated, the lever bolt 144b located in the groove 143b moves toward the clamp lever 144a. Along with this movement, the inner support column 143 moves toward the clamp lever 144a. When further rotated, the outer surface 143c of the inner support column 143 and the inner surface 142c of the outer support column 142 are pressed against each other. The movement of the inner support column 143 is restricted by the frictional force generated at this time and is stationary at a predetermined position (see FIG. 18).

[0081] The support tool 10 can be used in various forms. For example, as shown in FIG. 19, the support column 140 can be laid down and adsorbed on the adsorption surface of the adsorbed object in a state where the upper plate 111 and the lower plate 112 intersect (the first position), or as shown in FIG. 20, it can be adsorbed on the fixing portion 9 or the adsorption surface of the adsorbed object in a state where the upper plate 111 and the lower plate 112 overlap (the second position). Also, the support column 140 can be erected and adsorbed on the adsorption surface in a state where the upper plate 111 and the lower plate 112 intersect. Furthermore, it can be used in a state where the inner support column 143 is extended to a predetermined height.

[0082] A modification of the support 10 will be described. Since the modification has the same configuration as the embodiment, mainly the different configurations will be described. For the same configurations as the embodiment, the same reference numerals are used, and for the different configurations, the reference numerals in the 200s are used for Modifications 1 and 2, and the reference numerals in the 300s are used for Modification 3.

[0083] <Modification 1 of the support 10> As shown in FIGS. 25(a) and (b), the pedestal 210 has an upper plate 211 and a first plate 212. Pedestal shafts 213 are provided at both ends of the upper plate 211, and support both the upper plate 211 and the first plate 212. Thereby, the upper plate 211 and the first plate 212 are rotatably connected.

[0084] Magnetic bodies 221 and 222 are fixed to the lower surfaces of both ends of the first plate 212 with elastic bodies 261 interposed therebetween. The magnetic body 221 is located directly below the end of the upper plate 211, and the magnetic body 222 is located at the tip of the first plate 212.

[0085] Depending on the situation of the adsorption surface, as shown in FIG. 25(a), the upper plate 211 and the first plate 212 may be arranged at a right angle, or as shown in FIG. 25(b), they may be arranged linearly.

[0086] <Modification 2 of the support 10> As shown in FIGS. 26(a) and (b), the pedestal 210a has an upper plate 211, a first plate 212a, and a second plate 212b. Pedestal shafts 213a are provided at both ends of the upper plate 211, and support the upper plate 211, the first plate 212a, and the second plate 212b. Thereby, the upper plate 211, the first plate 212a, and the second plate 212b are rotatably connected.

[0087] The magnetic body 221a is fixed to the lower surface of the tip of the first plate 212a with an elastic body 261 interposed therebetween. Also, the magnetic body 221b is fixed to the lower surface of the tip of the second plate 212b with an elastic body 261 interposed therebetween. In order to make the heights of the magnetic body 221a and the magnetic body 221b the same to form a flat adsorption surface, it is preferable to attach an adjustment plate (not shown) between the magnetic body 221a and the first plate 212a.

[0088] Depending on the condition of the suction surface, as shown in Fig. 26(a), the upper plate 211, the first plate 212a, and the second plate 212b may be arranged at the same angle, or may be arranged linearly as shown in Fig. 26(b).

[0089] <Supporting tool 10 Modification 3> As shown in Figs. 27 to 30, since Modification 3 has the same configuration as the embodiment, mainly different configurations will be described. The same configurations as those in the embodiment are denoted by the same reference numerals, and different configurations are denoted by reference numerals in the 300s.

[0090] As shown in Fig. 27, Supporting tool 10 Modification 3 has a configuration in which, in addition to the supporting tool 10 of the embodiment, a stand 310 is further provided. The stand 310 is for weakening the suction force acting on other steel metal members etc. by being adsorbed to the pedestal portion 110. Thereby, the storage management of the supporting tool 10 during non-operation becomes easy.

[0091] As shown in Fig. 28, the stand 310 has a stand upper plate 311 and a stand lower plate 312. The stand upper plate 311 and the stand lower plate 312 are pivotally supported with a predetermined interval provided on a stand shaft 313. Thereby, the stand upper plate 311 and the stand lower plate 312 are rotatably connected.

[0092] A pair of non-magnetic bodies 321, 321 and a pair of non-magnetic bodies 322, 322 are mounted on the upper surface of the stand upper plate 311. When the stand upper plate 311 and the stand lower plate 312 overlap, that is, when in the second position, the pair of non-magnetic bodies 321, 321 are connected to the stand upper plate 311 via the pair of non-magnetic bodies 322, 322, and the pair of non-magnetic bodies 321, 321 are connected to the stand upper plate 311 via the pair of non-magnetic bodies 322, 322.

[0093] A pair of non-magnetic bodies 322a, 322a are mounted on the upper surface of the stand lower plate 312. As shown in FIG. 28, when the stand upper plate 311 and the stand lower plate 312 overlap at the first position, the pair of non-magnetic bodies 322a, 322a are in contact with the lower surface of the stand upper plate 311 in a state of being positioned directly below the pair of non-magnetic bodies 322, 322. The rotation of the stand upper plate 311 and the stand lower plate 312 is restricted, and the overlapping state is maintained. The non-magnetic body is preferably a material that is softer than a steel material and is not magnetized, such as a resin plate, a vinyl plate, etc. This can prevent the support 10 from being magnetically attracted to other metal materials during transportation.

[0094] A pair of rubber legs 311a, 311a are mounted on the lower surfaces of both ends of the stand upper plate 311, and a pair of rubber legs 312a, 312a are mounted on the lower surfaces of both ends of the stand lower plate 312. When the stand upper plate 311 and the stand lower plate 312 intersect and come into contact with each other, the lower ends of the rubber legs 311a, 312a are located on the same plane. Also, the upper ends of the non-magnetic bodies 321, 322, and 322a are located on the same plane. Thereby, when the stand upper plate 311 and the stand lower plate 312 intersect, that is, in the state of the first position, the support 10 can be installed on a flat surface by connecting the pedestal portion 110 to the stand 310 (see FIGS. 29 and 30).

[0095] As shown in FIG. 6 and the like, the electrical appliance 11 is attached to the upper end portion of the support 10 by an attachment tool 12. If a lighting lamp is attached to the support 10 as the electrical appliance 11, it can be supplied from the power supply unit 8 to a balloon light that has been commonly used for night construction in the past, or an equivalent power-saving lamp with the same performance, and the lighting effect will be further enhanced. By changing the positions of the arm 6 and the support 10, it is possible to perform both near and far lighting simultaneously. Since there is no engine noise, quiet construction can be carried out without causing trouble to the neighbors. It is easy to hear voices during construction meetings.

[0096] Although the illustration is omitted, it goes without saying that as the electrical appliance 11, in addition to a lighting lamp, it can also be used for wireless communication devices and the like. As a wireless communication device, for example, if a wireless router is installed, communication can be carried out between a mobile phone device in the vicinity and a remote location. If the electrical appliance 11 is a WiFi station, a WiFi environment can be constructed by supplying power to it.

[0097] The electrical appliance 11 can be used for a surveillance camera or a surveillance camera with a night vision mode. If a camera and a communication device are respectively installed, in the event of theft or the like, evidence preservation and prompt notification of theft or the like can be carried out. If a lighting lamp and a camera are respectively installed as the electrical appliance 11 on the support 10, it is convenient for creating a report of night work. The direction and position of the solar panel 5 can be adjusted according to the on-site situation. Night lighting enables shortening of time and improvement of efficiency for outdoor work, road work, etc.

[0098] If a blower and a mist supply machine are used in combination as the electrical appliance 11, the mist can be diffused over a long distance, so effective heatstroke prevention measures are possible. Similarly, if the mist contains a bactericide, space disinfection can be carried out as a countermeasure against corona. For example, a pair of fixing parts (not shown) are provided on the upper part of the power supply unit 8, a tank (not shown) is attached to this fixing part, the tank stores water containing water or a bactericide, etc., and supplies it to a mist nozzle (not shown) etc. via a water pump, and a blower fan may be provided above the mist nozzle. An environmental measurement instrument may be installed as the electrical appliance 11, and for example, it can be used for observing landslides and the like.

[0099] The electrical appliance 11 can be selectively arranged at any of at least a first position where it stops at a position lower than the three-dimensional structure part 4, a second position P2 (see Fig. 6 etc.) where it stops at a position higher than the three-dimensional structure part 4, and a third position P3 (see Fig. 6, Fig. 10 etc.) where the arm 6 and the support 10 stop in a developed state in the left-right direction of the three-dimensional structure part 4 due to the undulation of the support 10 and the rotation of the arm 6. The electricity generated by the solar panel 5 is stored in the power supply unit 8, and the electricity is supplied from the storage battery to the electrical appliance 11.

[0100] The telescopic mechanism 13 connects the frame sides of the upper solar panel 5 and the lower solar panel 5. The telescopic mechanism 13 is, for example, a belt-shaped gas spring filled with gas.

[0101] One end of the telescopic device 14 is fixed to the connecting portion 3e that connects the inclined pipe 4b, and the other end is fixed to the lower solar panel 5, and is located at an intermediate position in the height direction of the three-dimensional structure portion 4. As shown in FIGS. 4, 5, etc., the elevation angle of the solar panel 5 can be changed by the expansion and contraction of the telescopic device 14. For example, this elevation angle can be variably set within the range of 30° to 54°. The telescopic device 14 is exemplified by, for example, a universal stay.

[0102] The power supply box 15 is electrically connected to the power supply unit 8 and has output terminals (not shown), and is provided at the connecting portion 3e that connects the inclined pipe 4b.

[0103] The first cover 16 covers the top surface, front surface, and back surface of the power supply unit 8, and a pair of second covers 17 cover the side surfaces of the power supply unit 8. The second cover 17 having the ventilation holes 17a is attached to the bottom plate 4a via the hinge 4g so as to be able to undulate (see FIG. 3). The second cover 17 can be locked in the standing state by the locking portion 18.

[0104] The operation and usage method of the mobile power supply device 1 will be described. When transporting to the target location, the mobile power supply device 1 is set to the storage state shown in FIGS. 1 and 2. The mobile power supply device 1 is loaded on a transportation means such as a truck or a container and moved to the target location. After that, after being installed at a desired position, as shown in FIGS. 4 and 5, the telescopic mechanism 13 and the telescopic device 14 that connect the solar panel 5 are displaced to deploy the solar panel 5 in an appropriate posture. As shown in FIGS. 6 and 7, the arm 6 is deployed 90° in the front-rear direction, the support 10 and the electrical appliance 11 are attached to the other end 6b of the arm 6, and the height of the support 10 is adjusted as appropriate. While charging the solar panel 5, electricity is supplied to the electrical appliance 11.

[0105] Figures 8 and 9 show the case of working at night. The solar panel 5 is folded and arranged along the axial direction of the inclined pipe 4b. In the cases of Figures 10 and 11, the deployment angle is 170° due to further rotation of the arm 6. Figures 12 and 13 show the case of working at night at this deployment angle. When moving the mobile power supply device 1 to another location, it is changed to the storage state in the reverse procedure of the above.

[0106] The usage mode of the support 10 will be described. Figure 21 shows the state where the upper plate 111 and the lower plate 112 of the support 10 are set to the second position and adsorbed to the torii part 71 of the work vehicle 70 for use. The work vehicle 70 in this case is a truck for transporting materials and the like. Figure 22 shows the state where the upper plate 111 and the lower plate 112 are set to the second position and adsorbed to the rear part 72 of the work vehicle 70 for use. Figure 23 shows the state in the first position, adsorbed to the body 73 of the work vehicle 70 via the magnet sheet 75. Figure 24 shows the state in the first position, adsorbed to the bonnet 81 of the work passenger vehicle 80 via the magnet sheet 75. Note that the magnet sheet 75 is used to protect the painted surface.

[0107] According to the mobile power supply device 1 described above, the following effects are achieved.

[0108] According to the mobile power supply device 1 of the present invention, it can be applied to many uses such as communication functions, monitoring functions, blower functions, cooling functions, and / or lighting. The support strength and stability of the solar panel 5 are present, while facilitating the operation of adjusting the elevation angle etc. of the solar panel 5, making the overall structure compact, expanding the position and the range covered by the functions of the electrical utilization body 11, and facilitating repair and maintenance.

[0109] Since the mobile power supply device 1 can be loaded on a truck and moved, it is possible to utilize the electrical utilization body 11 over a wide regional range while loaded on the truck. By operating the arm 6 and the support 10, the position of the electrical utilization body 11 can be easily and freely changed.

[0110] The operation and effect of the mobile power supply device 1 will be described. Since the arm 6 can be in either a folded state or an expanded state with respect to the attachment portion 3, the movement range of the arm 6 is expanded. Since the support 10 can be removed from the fixing portion 9, the electrical appliance 11 can be utilized at another location away from the mobile power supply device 1.

[0111] The attachment and detachment of the support 10 to and from the fixing portion 9 is easy, and the workability is greatly improved.

[0112] The movement of the mobile power supply device 1 and the rotation of the arm 6 are facilitated.

[0113] In the stored state of the mobile power supply device 1, the whole can be made compact. According to the three-dimensional structure portion 4, a structure that is strong against wind pressure can be realized with a simple configuration. Since the power supply portion 8 is connected to the bottom plate 4a, it is strong against wind pressure on the basis of a simple configuration. In particular, it is possible to prevent the torsion and deformation of the three-dimensional structure portion 4 via the solar panel 5 due to wind pressure. The wind vent hole 5c can reduce the wind pressure applied to the solar panel 5.

[0114] The connecting portion 3e serves the role of reinforcing the truss structure and fixing the power box 15, and can facilitate access to the power supply. The connecting portion 3e can also serve the role of assisting in changing the elevation angle.

[0115] By locking the second cover 17, theft of the power supply portion 8 can be prevented. Maintenance of the power supply portion 8 is facilitated.

[0116] Since the plurality of solar panels 5 are connected by hinges 5a so as to be foldable around the rotation axis F, the folding operation of the solar panels 5 is easy, and the shadow of a person, the arm 6, or the support 10 is less likely to be reflected on the light collecting surface of the solar panel 5. There is an advantage that there is no interference with the solar panel 5, such as a person's shadow, the arm 6, the support 10, etc. blocking sunlight.

[0117] The elevation angle of the solar panel 5 can be changed with a simple configuration by the telescopic device 14.

[0118] The arm 6 and the support 10 enable the position of the electrical appliance 11 to be adjusted over a wide range in the vertical direction compared to the three-dimensional structure part 4 and the size of the solar panel 5.

[0119] By deforming the arm 6 and the support 10, storage, transportation, folding, and angle change become easy.

[0120] Compared to the three-dimensional structure part 4 and the size of the solar panel 5, the position of the electrical appliance 11 can be adjusted over a wide range in the horizontal direction.

[0121] Interference between the arm 6 or the support 10 and the solar panel 5 can be prevented.

[0122] The support 10 can improve work efficiency by appropriately selecting the object to be adsorbed. Also, the applicable range can be expanded by attaching electrical appliances other than the lighting lamp.

[0123] Regarding the convenience of the support 10, the situation of using it for night work involving the movement of workers will be described as an example. In night work, it is common to use a projector equipped with a generator to ensure a predetermined illuminance within the work area. A projector equipped with a generator is extremely heavy, and it is common to use a truck with a crane to unload, install, and remove it. Also, in mobile work involving the movement of the work location, a situation may occur where the predetermined illuminance required for the work cannot be obtained due to the movement. When such a situation is assumed, it is necessary to take measures such as moving a balloon projector equipped with a generator along with the movement of the work location, or installing a balloon projector in a location where movement is assumed in advance.

[0124] When the support tool 10 is detached from the fixing part 9 and the support tool 10 adsorbed to the work vehicle 70 is used, the electric appliance 11 can be projected onto the site area with the electric appliance 11 attached to the support tool 10. Further, the electricity required for the projector can be directly supplied from the work vehicle 70 by using, for example, a cigarette power source. When the power supplied from the work vehicle 70 is not sufficient for the light emission of the projector, a portable power source may be mounted on the work vehicle 70. Further, the work vehicle 70 may be moved as the work location is moved. That is, when using the support tool 10, it is sufficient to adsorb the support tool 10 with the projector attached to the work vehicle 70, and there is no need to separately use a vehicle with a crane or the like for loading and unloading in the work of installing and removing the projector.

[0125] As an advantage of being able to separate the support tool 10 from the fixing part 9 and use the electric appliance 11, when the place where the electric appliance 11 is used is not exposed to sunlight due to the influence of buildings, trees, etc., the mobile power supply device 1 is placed in a solar radiation area where power generation is possible, and the electric appliance 11 can be installed and operated at the target location (the power cable is extended as necessary).

[0126] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, an aluminum frame is frequently used for the three-dimensional structure part 4 and the like, so that transportation and movement can be facilitated.

Industrial Applicability

[0127] The mobile power supply device of the present invention is applicable to various construction works associated with construction civil engineering works, material storage yards, rest areas, events, camps, farms, heat stroke countermeasures, corona countermeasures, etc., and its functions can also utilize a wide range of functions such as lighting, monitoring, cooling, and ventilation. The mobile power supply device can improve work efficiency by attaching various electric appliances. In a situation where there are magnetic bodies and adsorbed bodies, it can also be considered for use as a mobile power supply device for use at home or for leisure. The industrial applicability of the present invention is great.
