Description

[Technical Field]

[0001] The present invention relates to a dismantling tool for dismantling a photovoltaic module, and more particularly to a dismantling tool for manually dismantling the frame and / or terminal block of a photovoltaic module. [Background technology]

[0002] Along with measures to reduce carbon dioxide emissions, the use of solar power generation modules (photovoltaic conversion modules) for renewable energy production is expected to increase. It is being considered to dismantle and recycle solar power generation modules when they are discarded (for example, Patent Document 1, etc.).

[0003] A photovoltaic power generation module (solar cell module) is composed of a flat solar cell panel (photoelectric conversion panel) that converts light energy into electrical energy, and a frame attached to the outer periphery of the solar cell panel. The frame has a fitting portion into which the outer periphery of the solar cell panel fits, and the fitting portion of the frame into which the outer periphery of the solar cell panel is fitted is filled with adhesive (sealant), so that the solar cell panel is firmly attached to the frame.

[0004] 24 is a schematic diagram showing the configuration of a photovoltaic power generation module (solar cell module) 1000. The photovoltaic power generation module 1000 basically has a structure in which a frame (aluminum frame) 1000, glass 1200, a sealing material 1300, cells (solar cells) 1350, a sealing material 1370, and a back sheet 1380 are stacked. In the example shown, a terminal block 1400 (or an injection box) is attached to the back sheet 1380. In the photovoltaic power generation module 1000, sealing materials (adhesive, sealant) 1300 and 1370 are present in the fitting portion of the frame 1100 and firmly adhere, so that disassembly is not easy.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2023-41467 Summary of the Invention [Problem to be solved by the invention]

[0006] As we approach an era in which photovoltaic modules (solar cell modules) will be disposed of in large quantities, solutions for recycling the modules are needed. It is clear that unless an efficient and low-cost method for dismantling large and heavy modules can be established for recycling, industrial waste disposal companies will not actively collect and dismantle the modules.

[0007] Although an electric demolition machine has been proposed for dismantling the module (1000) and the frame (1100), when using the electric demolition machine to dismantle the module (1000) and the frame (1100) on-site (for example, when dismantling modules at a temporary storage site for disposal, such as a power generation facility), the demolition machine needs to be transported by a large vehicle, and a power source needs to be secured, which is inconvenient. Furthermore, in places where the demolition machine cannot be used, the module or frame needs to be dismantled after being transported to the location where the demolition machine is installed, which is also inconvenient.

[0008] When such an electric dismantling device is not used, the module (1000) and frame (1100) must be dismantled manually. When dismantling the module or frame manually, it is possible to cut the frame using a tool such as an electric saw, but this is not desirable as it can cause sparks when cutting and is a highly dangerous operation.

[0009] Furthermore, while it is possible to manually remove the terminal block 1400 (injection box) using tools such as scrapers, hammers, and wire shears, depending on the tools used, it may take longer than expected. Furthermore, if it takes longer than expected, the worker will become extremely fatigued and the risk of injury increases. Additionally, when dismantling by hand, there is a high risk of the glass (1200) breaking depending on the tools and methods used.

[0010] If an electric dismantling machine is used, it may be possible to dismantle the frame (1100) and terminal block (1400) of one module (1000) in about one minute without breaking the glass (1200), etc. However, it is practically difficult to dismantle a module by hand without breaking the glass and in the same short time as with a dismantling machine.

[0011] Under these circumstances, the inventors of the present invention have been working diligently to find a way to create a dismantling tool that can manually dismantle the frames of photovoltaic power generation modules without using an electric dismantling device, and have arrived at the present invention. The present invention has been made in consideration of these circumstances, and its main purpose is to provide a dismantling tool that can relatively easily manually dismantle the frames and / or terminal blocks of photovoltaic power generation modules. [Means for solving the problem]

[0012] The dismantling tool according to the present invention is a tool for dismantling solar photovoltaic modules, and includes a dismantling body that houses the terminal blocks of the solar photovoltaic modules, and a dismantling blade attached to the bottom side of the dismantling body. The dismantling body has a storage space inside where the terminal blocks are placed, and the cutting tip of the dismantling blade is located in the storage space.

[0013] In a preferred embodiment, the disassembly body has a cubic shape. The back surface of the disassembly body is located on the opposite side to the side where the cutting tip of the disassembly blade is located. When the terminal block of the photovoltaic module is stored in the disassembly body, when a force is applied to the back surface of the disassembly body, the cutting tip of the disassembly blade advances to disassemble the terminal block.

[0014] In a preferred embodiment, a bottom opening is provided on the bottom surface of the disassembly main body.

[0015] In a preferred embodiment, openings are provided on the top, side and rear surfaces of the disassembly body.

[0016] In a preferred embodiment, the disassembly body has a cubic shape. The back surface of the disassembly body is located on the opposite side to the cutting tip of the disassembly blade. When a force is applied to the back surface of the disassembly body, the front surface of the disassembly body moves forward to disassemble the frame of the photovoltaic power generation module.

[0017] In a preferred embodiment, the dismantling blade has a tapered shape that becomes thinner toward the cutting tip.

[0018] Another dismantling tool according to the present invention is a dismantling tool for dismantling photovoltaic modules, and includes a first flat member on which a dismantling blade is disposed, a first extension member connected perpendicularly to the first flat member, a second extension member disposed parallel to the first extension member, and a connecting member connecting the first extension member and the second extension member. The connecting member has a structure that allows the distance between the first extension member and the second extension member to be adjusted.

[0019] In a preferred embodiment, the first flat member has a plurality of dismantling blades arranged in parallel, and the first flat member and the first extension member form an L-shaped member.

[0020] In a preferred embodiment, the connecting member is a screw member.

[0021] In a preferred embodiment, the screw member has a bolt structure, and a nut is provided on the screw member.

[0022] In a preferred embodiment, the dismantling blade disposed on the first flat member has a configuration that allows it to be inserted into a gap in a frame of the photovoltaic power generation module.

[0023] The disassembly tool set according to the present invention is a disassembly tool set for disassembling a photovoltaic power generation module, and includes the above-mentioned disassembly tool and the other disassembly tool. [Effects of the Invention]

[0024] The dismantling tool according to the present invention includes a dismantling body that houses the terminal blocks of a solar photovoltaic module and a dismantling blade attached to the bottom of the dismantling body, with the cutting tip of the dismantling blade positioned within the storage space. Therefore, by applying force to the dismantling body and advancing the cutting tip of the dismantling blade, the terminal blocks of the solar photovoltaic module can be dismantled (cut). Further advancing the dismantling body allows the frame of the solar photovoltaic module to be dismantled. As a result, a dismantling tool is realized that allows the frame and / or terminal blocks of a solar photovoltaic module to be dismantled relatively easily by hand.

[0025] Another dismantling tool according to the present invention includes a first flat member on which a dismantling blade is disposed, a second extension member disposed parallel to a first extension member connected perpendicularly to the first flat member, and a connecting member connecting the first extension member and the second extension member. The connecting member is configured to allow the spacing between the first extension member and the second extension member to be adjusted. The dismantling blade is configured to be insertable into a gap in the frame of a solar photovoltaic module. Furthermore, by adjusting the spacing between the first extension member and the second extension member with the connecting member, the frame of the solar photovoltaic module can be clamped between the first extension member and the second extension member. This allows the frame of a solar photovoltaic module to be dismantled relatively easily by hand by sliding the other dismantling tool according to the present invention.

[0027] The following describes preferred embodiments of the present invention with reference to the drawings. In the following drawings, for the sake of simplicity, the same reference numerals are used to designate components and parts that perform the same functions, and redundant explanations may be omitted or simplified. Furthermore, while the dimensional relationships (length, width, thickness, etc.) in each drawing are intended to basically satisfy the dimensional relationships, they may not necessarily accurately reflect the actual dimensional relationships.

[0028] Furthermore, matters necessary for carrying out the present invention other than those specifically mentioned in this specification can be understood as design matters for a person skilled in the art based on the prior art in the relevant field. The present invention can be carried out based on the contents disclosed in this specification and drawings and the common general technical knowledge in the relevant field. In addition, the present invention is not limited to the following embodiments.

[0029] FIG. 1 is a perspective view schematically illustrating the configuration of a dismantling tool 100 according to an embodiment of the present invention. In FIG. 1, thicknesses of components are omitted to simplify the explanation of the dismantling tool 100 according to this embodiment. FIGS. 2, 3, and 4 are a top view, a bottom view, and a side view, respectively, illustrating the configuration of the dismantling tool 100 according to this embodiment. FIGS. 5 and 6 are a front view and a back view, respectively, illustrating the configuration of the dismantling tool 100 according to this embodiment.

[0030] The dismantling tool 100 of this embodiment is a tool (dismantling tool, dismantling tool) for dismantling a photovoltaic power generation module. Specifically, the dismantling tool 100 is a dismantling tool (dismantling tool) used when dismantling a terminal block 1400 (or an injection box) and / or a frame 1100 (for example, an aluminum frame) of a photovoltaic power generation module (solar cell module, photoelectric conversion module) 1000 as shown in Fig. 24 .

[0031] As shown in Fig. 1, the dismantling tool 100 of this embodiment is composed of a dismantling main body 10 that houses a terminal block 1400 (see Fig. 24) of the photovoltaic power generation module 1000. A dismantling blade 20 is provided on the bottom surface 12 side of the dismantling main body 10. A storage space 30 is provided inside the dismantling main body 10 in which the terminal block (injection box) 1400 is disposed. As shown in Figs. 2 and 3, a cutting tip 21 of the dismantling blade 20 is located in the storage space 30 of the dismantling main body 10.

[0032] In the configuration of this embodiment, the disassembly main body 10 has a cubic shape. This cubic shape corresponds to the basic shape of the terminal block (injection box) 1400. It is acceptable for the disassembly main body 10 to have other shapes, but a cubic shape is often more convenient for use and manufacturing. The cubic shape of the disassembly main body 10 does not need to be geometrically strict. The corners may be rounded rather than right angles, the side surfaces 13 may be inclined or curved, and the top surface 11 may be inclined or curved. However, it is often preferable for the side surfaces 13 and / or the top surface 11 to be flat (and / or perpendicular to adjacent surfaces), at least for the sake of inexpensive manufacturing.

[0033] The back surface 15 of the dismantling main body 10 is located on the opposite side to the side where the cutting tip 21 of the dismantling blade 20 is located. When the terminal block 1400 (see FIG. 24) of the photovoltaic power generation module is stored inside the dismantling main body 10 (storage space 30), applying force to the back surface 15 of the dismantling main body 10 causes the cutting tip 21 of the dismantling blade 20 to move forward (see arrow 90) and dismantle (or cut) the terminal block 1400.

[0034] As shown particularly in FIG. 3, a bottom opening 33 is provided on the bottom surface 12 of the dismantling main body 10. The bottom opening 33 has dimensions that allow the terminal block 1400 of the photovoltaic power generation module to fit smoothly during the dismantling process (dismantling work). While the dimensions are not particularly limited, as an example, the bottom opening 33 has dimensions of 150 mm (±50 mm) × 150 mm (±50 mm). In the example shown in FIG. 3, the bottom opening 33 is square in shape, but it may be rectangular (or another shape).

[0035] In the example shown in FIG. 3, the dimensions of the bottom surface 12 (and similarly, the top surface 11) of the dismantling body 10 are 325 mm (±50 mm) in the longitudinal direction (horizontal direction) and 210 mm (±50 mm) in the vertical direction. The width of the members extending in the longitudinal direction (horizontal direction) of the dismantling body 10 is, for example, 30 mm (±10 mm), and the width of the members extending in the vertical direction of the dismantling body 10 is, for example, 25 mm (±10 mm). Additionally, in this example, the width (vertical direction) of the dismantling blade 20 is 210 mm (±50 mm), and the vertical dimension of the cutting tip 21 exposed in the bottom opening 33 is 150 mm (±50 mm). The longitudinal (horizontal) dimension of the dismantling blade 20 is 150 mm (±50 mm).

[0036] In addition, in the configuration of this embodiment, an opening (top opening) 31 is provided on the top surface 11 of the disassembly main body 10. Furthermore, an opening (side opening) 35 is provided on the side surface 13 of the disassembly main body 10. In addition, an opening (rear opening) 37 is provided on the back surface 15 of the disassembly main body 10. The provision of the openings (31, 35, 37) in this manner makes it easy to visually inspect the terminal block 1400 (see FIG. 24 ) stored inside the disassembly main body 10 (storage space 30). Being able to visually inspect the terminal block 1400 is convenient because it allows immediate confirmation during the disassembly process of whether the terminal block 1400 has been removed (disassembled). Furthermore, the provision of the openings (31, 35, 37) allows the wiring connected to the terminal block 1400 to be routed to the outside through the openings, which has the advantage of facilitating the disassembly of the terminal block 1400. As shown in the configuration, openings (31, 35, 37) may be provided on all of the top surface 11, side surfaces 13, and back surface 15 of the disassembly main body 10, or at least one of them (for example, top surface opening 31) may be provided, or two of them may be provided. Also, in the example shown, side surface openings 35 are provided on both (both sides) of the side surfaces 13 of the disassembly main body 10, but there are also cases where side surface openings 35 may be provided on only one side.

[0037] The dismantling tool 100 of this embodiment is made of metal. Specifically, the dismantling main body 10 constituting the dismantling tool 100 is made of, for example, iron, stainless steel, aluminum, or the like. The dismantling tool 100 (dismantling main body 10) has the strength to apply force to the back surface 15 to dismantle (cut, break, etc.) the terminal block 1400 (and the frame 1100). As long as it has such strength, the dismantling tool 100 (dismantling main body 10) may be made of a material other than metal (for example, ceramic, resin (engineering plastic, etc.)).

[0038] The disassembly blade 20 of this embodiment is made of metal (e.g., stainless steel, iron). The thickness of the disassembly blade 20 is, for example, 1 mm, but is not limited to this. The disassembly blade 20 may be made of a material other than metal (e.g., ceramic) as long as it can disassemble (cut, destroy, etc.) the terminal block 1400 (and the frame 1100), but metal is often more cost-effective. The disassembly blade 20 may also have a tapered shape that becomes thinner toward the cutting tip 21, as shown in FIG. 7 . In other words, the disassembly blade 20 may have an inclined surface 25 that tapers from the rear end 23 of the disassembly blade 20 toward the cutting tip 21.

[0039] Next, a process for dismantling the terminal block 1400 (or injection box) and the frame 1100 (for example, an aluminum frame) of the photovoltaic power generation module 1000 using the dismantling tool 100 of this embodiment will be described with reference to Fig. 8 to Fig. 12. Fig. 8 to Fig. 12 are process diagrams for explaining the dismantling process (dismantling method) for dismantling the photovoltaic power generation module 1000 using the dismantling tool 100.

[0040] First, as shown in Fig. 8(a), a photovoltaic power generation module 1000 to be disassembled is prepared. Here, the photovoltaic power generation module 1000 is placed so that the back surface 1500 on which the terminal block 1400 (injection box) of the photovoltaic power generation module 1000 is located faces up. In the illustrated example, wiring 1410 extends from the terminal block 1400.

[0041] Next, as shown in FIG. 8(b), the dismantling tool 100 of this embodiment is placed so as to cover the terminal block 1400 of the photovoltaic power generation module 1000. Specifically, the dismantling tool 100 is placed on the back surface 1500 of the photovoltaic power generation module 1000, and the terminal block 1400 is stored in the storage space 30 of the dismantling tool 100 (i.e., inside the dismantling main body 10). In the illustrated example, the wiring 1410 of the terminal block 1400 is exposed from the top opening (31), but it may also be exposed from the side opening (35). Thereafter, the dismantling tool 100 is moved in the direction of the arrow 90 to dismantle (destroy, cut) the terminal block 1400.

[0042] 9(a) and 9(b), the jack 50 is set in a position so that it can push the rear surface 15 of the dismantling tool 100. In the illustrated example, a large farm jack (manual jack) is used as the jack 50.

[0043] In this embodiment, the jack 50 has a jack body 53 through which a rail 55 passes, and a handle 57 for jacking up and down attached to it. The jack 50 also has a first support part 51 that is basically placed on the ground, and a second support part 52 (plate) for lifting and lowering. Here, the first support part 51 is set on the frame 1100, and the second support part 52 (plate) is set on the back surface 15 of the demolition tool 100. In this state, when the handle 57 is moved to jack up, the demolition tool 100 moves in the direction of the arrow 90.

[0044] In this embodiment, a relatively large firm jack is used, but a smaller one can be used as long as it has sufficient dismantling force. Other jacks may be used instead of a firm jack, and other tools (pressure application devices or devices that apply pressure) may be used instead of a jack as long as the terminal block 1400 can be dismantled by pushing the rear face 15 of the dismantling tool 100. Although the purpose is manual dismantling, this does not prohibit the use of electric tools (electric jacks, electric pressure application devices) as long as the terminal block 1400 can be dismantled on the spot. In some cases, it may be preferable to use an electric jack to push the rear face 15 of the dismantling tool 100 to dismantle the terminal block 1400.

[0045] Next, as shown in FIG. 10 , each time the jack 50 is jacked up using the handle 57, the dismantling tool 100 moves in the direction of the arrow 90. As a result, the dismantling blade 20 located on the underside of the dismantling tool 100 gets under the terminal block 1400 and can remove the terminal block 1400. In this way, the terminal block 1400 can be dismantled relatively easily. When a manual jack 50 is used, the terminal block 1400 can be dismantled manually and smoothly.

[0046] Next, as shown in FIGS. 11(a) and (b), if the jacking continues even after the terminal block 1400 is removed, the dismantling tool 100 reaches the frame 1100. If the jacking continues in this state, the dismantling tool 100 (particularly the front surface 14) pushes against the frame 1100, causing the frame 1100 to break (collapse), as shown in FIGS. 12(a) and (b). FIG. 12(b) shows the connectors 1150 that connect the frames to each other inside the four corners of the four-sided frame protruding. When these connectors 1150 break or come out, the frame 1100 comes off, allowing the frame to be dismantled. By performing the same operation on other frames, the dismantling of all frames 1100 is completed.

[0047] The dismantling tool 100 of this embodiment is composed of a dismantling main body 10 that stores the terminal block 1400 of the photovoltaic power generation module 1000, and a dismantling blade 20 that is attached to the bottom surface (12) of the dismantling main body 10. The cutting tip 21 of the dismantling blade 20 is located in a storage space 30 provided inside the dismantling main body 10. By applying force to the dismantling main body 10 to advance the cutting tip 21 of the dismantling blade 20, the terminal block 1400 of the photovoltaic power generation module 1000 can be dismantled (cut). Furthermore, by further advancing the dismantling main body 10, the frame 1100 of the photovoltaic power generation module 1000 can be dismantled (damaged, broken, collapsed, etc.). As a result, the frame 1100 and / or the terminal block 1400 of the photovoltaic power generation module 1000 can be dismantled relatively easily by hand. In the above example, by jacking up with the jack 50, the dismantling main body 10 can conveniently dismantle the frame 1100 together with the terminal block 1400 of the photovoltaic power generation module 1000 in a single operation.

[0048] After the dismantling work (dismantling method) described above, i.e., after removing the frame 1100 and terminal block 1400 of the photovoltaic power generation module 1000, another dismantling work can be performed using a dismantling tool 200 as shown in FIG. 13.

[0049] Fig. 13 is a perspective view schematically illustrating the configuration of another dismantling tool 200 according to an embodiment of the present invention. In Fig. 13, thicknesses of components and the like are omitted to simplify the explanation of the dismantling tool 200 of this embodiment. Figs. 14 and 15 are a front view and a rear view, respectively, showing the configuration of the dismantling tool 200 of this embodiment. Furthermore, Fig. 16 schematically illustrates the state in which the dismantling tool 200 of this embodiment is set on the photovoltaic power generation module 100.

[0050] The dismantling tool 200 of this embodiment is a tool for dismantling a photovoltaic power generation module 1000. The dismantling tool 200 includes a first flat member 60 on which a dismantling blade 70 is arranged. The dismantling tool 200 further includes a first extension member 62 connected perpendicularly to the first flat member 60, and a second extension member 64 arranged parallel to the first extension member 62. A connecting member 80 is provided between the first extension member 62 and the second extension member 64 to connect the two (62, 64). The connecting member 80 has a structure that allows the distance between the first extension member 62 and the second extension member 64 to be adjusted.

[0051] In the configuration of this embodiment, multiple dismantling blades 70 are provided in parallel on the first flat member 60. In the illustrated example, three dismantling blades 70 (one on each side and one in the center) are attached to the first flat member 60. In the example shown in FIG. 15, the dismantling blades 70 are provided along the surface (e.g., the back surface) of the first flat member 60. The dismantling blades 70 are fixed to the first flat member 60 with adhesive, but may also be fixed with fixing members such as bolts. The dismantling blade 70 may be a single blade (e.g., one with a relatively large width), or there may be two, four, or more dismantling blades 70. It is preferable that the multiple dismantling blades 70 be arranged at equal intervals, but they do not necessarily have to be arranged at equal intervals.

[0052] The dismantling blade 70 of this embodiment is made of metal (e.g., stainless steel, iron). The thickness of the dismantling blade 70 is, for example, 1 mm, but is not limited to this. Furthermore, the dismantling blade 70 may have a tapered shape that becomes thinner toward the cutting tip, as shown in FIG. 7 above.

[0053] 16, in the configuration of this embodiment, the first flat member 60 and the first extension member 62 form an L-shaped member. In this example, the first flat member 60 and the first extension member 62 are one continuous member, and are configured so that the first flat member 60 and the first extension member 62 form a right angle.

[0054] The connecting member 80 of this embodiment is composed of a screw member. In the illustrated example, the screw member 80 has a bolt structure and is provided with nuts (81, 84). Specifically, the connecting member 80 is a bolt consisting of a threaded portion provided with a head 82, with a first nut 81 located in the center of the threaded portion 80 and a second nut 84 set on the tip side of the threaded portion 80. In this example, the connecting member 80 may be set in the reverse direction so that the head 82 is on top. In the illustrated example, a screw member is used as the connecting member 80, but other connecting members may also be used, for example, a clamp-type member (a connecting member with an adjustable distance) may also be used.

[0055] The first extension member 62 and the second extension member 64 are arranged by a connecting member 80 so that they are parallel to each other. The distance between the first extension member 62 and the second extension member 64 can be adjusted by turning (moving) a second nut 84 located on the tip side of the threaded portion 80. Note that a further extension member (third extension member) extending perpendicular to the second extension member 64 may be provided. In that case, the second extension member 64 and the third extension member may be L-shaped members.

[0056] As shown in FIG. 16 , the dismantling tool 200 of this embodiment is placed on the front panel 1200 (here, the glass panel 1200) of the photovoltaic module 1000 (see arrow 91). Next, the dismantling tool 200 is slid so that the dismantling blade 70 of the dismantling tool 200 is inserted into the gap 95 in the frame 1100 of the photovoltaic module. Specifically, the dismantling blade 70 of the dismantling tool 200 is inserted between the front panel 1200 and the frame 1100 of the photovoltaic module (95). Thereafter, when the dismantling tool 200 (dismantling blade 70) is moved along the surface of the front panel 1200, the frame 1100 can be dismantled by the cutting (disintegration) of the dismantling blade 70.

[0057] An adhesive (an adhesive made of components such as silicone) is present between the front panel 1200 of the photovoltaic module and the frame 1100, caulking the gap 95 and fixing it to the frame 1100, and this adhesive fixing can be peeled off and removed by the dismantling tool 200 (dismantling blade 70). Also, the front panel 1200 of the photovoltaic module 1000 may be on the back sheet 1380 side.

[0058] 16, the thickness of the first flat member 60, the thickness of the first extension member 62, and the thickness of the second extension member 64 are, for example, 2 mm to 10 mm (or 3 mm±1 mm). The length of the threaded portion 80 is, for example, 30 mm to 60 mm (or 50 mm±10 mm).

[0059] The dismantling tool 200 of this embodiment is constructed entirely of metal components, but other materials (such as ceramic or plastic) may be used for at least some parts. If constructed of metal components, an insulator such as rubber may be provided on the surfaces of parts other than the dismantling blade 70 to prevent electric shock. The dismantling blade 70 may be shaped like a mountain, semicircle, triangle, or rectangle. The dismantling tool 200 shown in the figure is constructed to be dismantled, but it may also be non-dismantled or a one-piece machined piece.

[0060] Next, a process for dismantling frame 1100 of photovoltaic power generation module 1000 using dismantling tool 200 of the present embodiment will be described with reference to Fig. 17 to Fig. 23. Fig. 17 to Fig. 23 are process diagrams for explaining a dismantling process (dismantling method) for dismantling photovoltaic power generation module 1000 using dismantling tool 200.

[0061] First, as shown in FIG. 17(a), a dismantling tool 200 of this embodiment is prepared. The illustrated dismantling tool 200 uses a third extension member 66 that extends perpendicularly to the second extension member 64. Therefore, L-shaped members are disposed on both the upper and lower sides of the connecting member 80. As shown in the figure, the presence of the third extension member 66 (the L-shaped members) has the advantage that it is easier to grasp with the hand (300). In addition, in this example, through holes 89 are provided in the first flat member 60, the first extension member 62, the second extension member 64 (and the third extension member 66). Providing the through holes 89 allows for weight reduction, but the through holes 89 are not essential.

[0062] The dismantling tool 200 of this embodiment can be disassembled as shown in Fig. 17(b). In the disassembled state, the structure of the first flat member 60 provided with the dismantling blade 70 (dismantling tool 250) can be used in the dismantling process.

[0063] FIG. 18(a) shows a state in which dismantling tool 250, which is part of dismantling tool 200, is placed on panel 1500 (here, back sheet 1380) of a photovoltaic module. Next, as shown in FIG. 18(b), dismantling blade 70 of dismantling tool 250 is inserted between frame 1100 and panel 1500 (gap 95). Thereafter, dismantling tool 250 is moved horizontally (translated) as shown by arrow 95 to peel off and remove the adhesive fastening in gap 95.

[0064] When using the dismantling tool 200 as is, bring it close to the solar power generation module panel 1200 (here, the glass 1200) as shown in Figure 19(a), and adjust the connecting member 80 to clamp the frame 1100 between the first extension member 62 and the second extension member 64 as shown in Figures 20(a) and (b).

[0065] Next, as shown in Figure 21(a), the dismantling tool 200 clamping the frame 1100 is moved horizontally (translationally) (arrow 96) and moved to the end of the frame 1100 as shown in Figure 21(b), completing the peeling and removal of the adhesive fastening in the gap 95. Next, as shown in Figure 22, the dismantling tool 200 is clamped and moved to the other frames 1100, completing the peeling and removal of the adhesive fastening in the gap 95. Once this is complete, as shown in Figure 23, the photovoltaic power generation module 1000 remains with the adhesive fastening in the gap 95 peeled and removed, so the frame 1100 is manually removed, completing the dismantling of the photovoltaic power generation module 1000.

[0066] The dismantling tool 200 of this embodiment is composed of a first flat member 60 on which a dismantling blade 70 is disposed, a first extension member 62 connected perpendicularly to the first flat member 60, and a second extension member 64 disposed parallel to the first extension member 62. The first extension member 62 and the second extension member 64 are connected (coupled) by a connecting member 80. The connecting member 80 has a structure that allows the distance between the first extension member 62 and the second extension member 64 to be adjusted. The dismantling blade 70 is configured to be insertable into a gap 95 in the frame 1100 of the photovoltaic power generation module 1000. Furthermore, by adjusting the distance between the first extension member 62 and the second extension member 64 with the connecting member 80, the frame 1100 of the photovoltaic power generation module 1000 can be clamped between the first extension member 62 and the second extension member 64. This allows the frame 1100 of the photovoltaic power generation module 1000 to be dismantled relatively easily by hand by sliding the dismantling tool 200.

[0067] As described above, by using the dismantling tools 100 / 200 of the present embodiment, the terminal block 1400 (injection box) and / or the frame 1100 (aluminum frame) of the photovoltaic power generation module 1000 can be efficiently dismantled and removed manually. Furthermore, by using manual labor, the tools used to dismantle the photovoltaic power generation module 1000 do not require electricity or fossil fuels, making the dismantling environmentally friendly. Furthermore, the module 1000 can be dismantled safely by manual labor without breaking the glass of the module 1000.

[0068] Furthermore, the demolition tools 100 and 200 of the present embodiment can be brought to the demolition site for demolition, eliminating the need for trucks or heavy machinery. Furthermore, even workers with limited physical strength can use them, contributing to job creation and local recycling-oriented industries. Furthermore, demolition work can be performed in mountainous areas or places without power sources, and they can be used indoors or outdoors without sparks, noise, or vibration. Furthermore, the demolition tools 100 and 200 of the present embodiment can be used to dismantle frames that have been covered in sand and dust and exposed to rain and snow for many years, causing sand and soil to infiltrate and become firmly stuck inside. Even industrial waste disposal companies that have difficulty installing large demolition equipment can dismantle and recycle the solar power generation module 1000. Another advantage is that the increased efficiency of dismantling and transportation contributes to reducing carbon dioxide emissions.

[0069] While the present invention has been described above using preferred embodiments, these descriptions are not limiting and various modifications are possible. Furthermore, the features of the above-described embodiments and modifications can be mutually applied, and modifications that would be obvious to those skilled in the art can be made.
