Description

Technical Field

[0001] The present invention relates to the technical field of the solar energy industry, and particularly to a photovoltaic module installation structure and a photovoltaic module. Background Art

[0002] Solar energy is a renewable energy source that is inexhaustible to humans. It has the advantages of sufficient cleanliness, absolute safety, relative universality, definite long life and maintenance-free, resource adequacy and potential economy, etc., and plays an important role in the long-term energy strategy. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface, and it is also the mainstream technology for using solar energy to generate electricity at present. A photovoltaic module is the core unit of photovoltaic power generation. Conventional photovoltaic modules usually consist of cover glass, EVA, solar cells, EVA, backsheet, junction box and aluminum alloy frame. And a photovoltaic power generation system forms a photovoltaic array by installing photovoltaic modules on a system bracket, and then cooperates with a storage battery, a controller and an inverter, etc. to generate electricity.

[0003] The Chinese invention patent with the application number: CN202210056861.6 proposes "a photovoltaic module installation structure". By adopting a crimping connection method, the photovoltaic module installation structure uses fewer components, is simple and fast to install, requires less labor, and has higher installation efficiency; the connection structure of the photovoltaic module installation structure is firm and not easily damaged under extreme conditions, and has a longer service life; for relatively large photovoltaic modules, auxiliary fixation can be carried out through the bracket fastening bolts, and the application range is wider.

[0004] However, the existing photovoltaic module installation structures and the above-mentioned comparative documents all have many defects, which are specifically as follows: The problem of gaps is prominent: Traditional mounting frames mostly adopt rigid connections or simple hinge connections. When multiple groups of installation structures are arranged side by side, hinges, connectors, etc. are exposed, and structural gaps are extremely likely to be formed. These gaps not only reduce the overall sealing performance, affect the appearance, but also easily accumulate water and dust, which will further cause corrosion problems and shorten the service life of the installation structure.

[0005] Insufficient installation adaptability: Fixed mounting frames are difficult to adapt to crossbars of different specifications of photovoltaic brackets, resulting in difficult installation processes. And the existing sliding adjustment mechanisms are complex in structure and lack anti-detachment designs, which makes the installation efficiency low, and the structural stability after installation is also poor, and problems such as looseness are likely to occur.

[0006] Single-function: Existing installation structures only have basic clamping functions and lack an effective mechanism for cleaning and maintaining the surface of photovoltaic modules. In order to maintain the power generation efficiency of photovoltaic modules, additional cleaning equipment needs to be configured, which undoubtedly increases the complexity and cost of the system.

[0007] Complicated extended connection: When splicing multiple groups of installation structures, independent connectors are relied on, which not only leads to redundant components, increases the complexity of the system, but also makes the operation process cumbersome. In addition, structural breakpoints are likely to form at the joints, affecting the strength and stability of the overall structure. Summary of the Invention

Specific embodiments

[0022] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1 to 19, the present invention provides a technical solution: a photovoltaic module installation structure, which includes a first mounting frame 1. Above the first mounting frame 1, a photovoltaic module body 46 is placed. Above the photovoltaic module body 46, a second mounting frame 2 is provided. One end of the first mounting frame 1 and the second mounting frame 2 is hinged by a hinge. The bottom surface of the first mounting frame 1 is slidably connected to a connecting plate 21. A connecting screw 22 is screwed on the bottom plate of the connecting plate 21. On both sides of the connecting plate 21, a traction plate 24 is inserted. One end of the traction plate 24 is fixed with a clamping plate 19. A rotating handle 25 is rotatably connected to the surface of the clamping plate 19. One end of the rotating handle 25 is fixed with a long handle screw 27. One end of the long handle screw 27 is screwed to the end of the connecting plate 21; both the first mounting frame 1 and the second mounting frame 2 are in the shape of a square frame structure. The first mounting frame 1 and the second mounting frame 2 clamp and limit the photovoltaic module body 46. On one side of both the first mounting frame 1 and the second mounting frame 2, a side groove 45 is opened. The side groove 45 and the hinge are symmetrically distributed with respect to the first mounting frame 1. During use, the photovoltaic module body 46 is placed in the groove of the first mounting frame 1, and then the second mounting frame 2 is covered above the photovoltaic module body 46. The side groove 45 is opened to accommodate the hinge of the adjacent mounting structure when two sets of mounting structures are arranged side by side, so as to ensure no gap after the two sets of mounting structures are connected side by side.

[0024] On one side of the first mounting frame 1, a reserved groove 3 is opened. Between the two parallel side walls of the reserved groove 3, a guide rod 4 is fixed. An embedding groove 6 is opened on the surface of the guide rod 4. A rubber strip 7 is fixed inside the embedding groove 6. A sliding sleeve 5 is sleeved on the rod body of the guide rod 4. The connecting plate 21 is in the shape of an "L" - shaped plate structure. The top end of the connecting plate 21 is fixed to the bottom surface of the sliding sleeve 5; on one side of the sliding sleeve 5, an installation groove 8 is opened. A blocking block 9 is fixed inside the installation groove 8. Two insertion openings 10 are opened on the surface of the installation groove 8. The two insertion openings 10 are symmetrically distributed with respect to the blocking block 9. A clamping block 11 is inserted into the insertion opening 10. Two limiting blocks 15 are fixed inside the installation groove 8. The limiting blocks 15 are in the shape of a "C" - shaped plate structure. The two limiting blocks 15 are symmetrically distributed with respect to the blocking block 9 and are located between the insertion opening 10 and the blocking block 9. A push plate 16 is inserted into the limiting block 15. The push plate 16 squeezes and clamps the rubber strip 7 by the clamping block 11; the width of the clamping block 11 is greater than the depth of the insertion opening 10. One end of the clamping block 11 close to the rubber strip 7 is provided with a clamping groove 12. The clamping groove 12 is in the shape of a "cross" - shaped groove. The other end of the clamping block 11 is provided with an inclined surface facing the limiting block 15, and a notch 13 is opened at the other end of the clamping block 11. An elastic rubber band 14 is fixed on the surface of the notch 13. Two ends of the elastic rubber band 14 are respectively fixed to the top surface and the bottom surface of the insertion opening 10. One end of the push plate 16 is fixed with a pulling plate 17. The pulling plate 17 is in the shape of an "I" - shaped plate structure. An elastic support plate 18 is fixed between the pulling plate 17 and the blocking block 9. The elastic support plate 18 is in the shape of a "U" - shaped plate structure. A rubber support block 20 is fixed between one end of the elastic support plate 18 and the blocking block 9.

[0025] During use, the number of sliding sleeves 5 sleeved on the rod body of the guide rod 4 is the same as the number of cross bars of the photovoltaic bracket with the supporting installation structure. That is, after the installation structure is laid on the photovoltaic bracket, the connecting plate 21 overlaps on the cross bar of the photovoltaic bracket. The connecting plate 21 and the cross bar are connected by connecting screws 22, and the two groups of clamping plates 19 are clamped on both sides of the cross bar to limit the anti-falling of the installation structure. When the position of the sliding sleeve 5 needs to be adjusted, two fingers respectively toggle the two pull plates 17, and the two fingers are closed to pull the two pull plates 17 to move towards the stopper 9. The pull plate 17 drives the push plate 16 to move towards the stopper 9. When the push plate 16 no longer blocks the socket 10, the rubber belt 14 is in the initial state. At this time, one end of the clamping block 11 extends into the installation groove 8. At this time, the sliding sleeve 5 can be toggled to slide along the guide rod 4. When the sliding sleeve 5 slides to the designated position, the two pull plates 17 are pushed. The pull plate 17 pushes the corresponding push plate 16 to squeeze the corresponding clamping block 11 along the inclined surface. The clamping block 11 retracts into the socket 10, and the clamping block 11 tenses the rubber belt 14 to deform. When the push plate 16 covers the notch of the socket 10, one end of the push plate 16 is inserted into the side wall of the installation groove 8, and the clamping block 11 clamps the rubber strip 7. The rubber strip 7 is deformed under pressure and squeezed into the card slot 12 to increase the friction between the clamping block 11 and the rubber strip 7, thereby braking the sliding sleeve 5 on the rod body of the guide rod 4. Adjust the position of the sliding sleeve 5 according to the position of the cross bar so that the connecting plate 21 below the sliding sleeve 5 overlaps on the cross bar. At this time, the connecting screw 22 is screwed through the bottom plate of the connecting plate 21 and inserted into the reserved hole on the surface of the cross bar, so as to fix the connecting plate 21 on the cross bar, and the connecting plate 21 does not protrude from the bottom of the mounting frame 1, ensuring that the bottom of the mounting frame 1 is laid flat on the cross bar.

[0026] A through hole 23 is opened at the end of the connecting plate 21, the traction plate 24 is inserted into the through hole 23, a rubber pad 29 is fixed at the bottom of the clamping plate 19, a limiting rotating groove is opened at the top of the clamping plate 19, the limiting rotating groove is an "I"-shaped circular opening, and a rotating handle 25 is rotatably connected inside the limiting rotating groove. The rotating handle 25 is an "I"-shaped circular block, and a screwing handle 26 is fixed at one end of the rotating handle 25 away from the long handle screw 27. Threaded grooves 28 are opened at both ends of the connecting plate 21, and one end of the long handle screw 27 is inserted and screwed into the threaded groove 28. During use, the clamping plates 19 are arranged on both sides of the connecting plate 21 to adjust the distance between the two clamping plates 19 to be equal to the width of the cross bar. In this way, when the connecting plate 21 overlaps above the cross bar, the two clamping plates 19 are distributed on both sides of the cross bar. At this time, when the connecting screw 22 is not connected to the cross bar, the installation structure will not fall off the cross bar due to the limitation of the clamping plate 19, and the clamping plate 19 does not protrude laterally from the reserved groove 3, so as to ensure that there is no gap after two groups of installation structures are assembled side by side.

[0027] The top surface of the second mounting frame 2 is provided with tube bundling grooves 30 at both ends. Below the tube bundling grooves 30, there is a gas collecting cavity 36, which is opened on the plate body of the second mounting frame 2. An air delivery pipe 31 is inserted into the interior of the tube bundling groove 30. A one-way valve head 33 is fixed on the pipe body of the air delivery pipe 31, and the bottom end of the one-way valve head 33 is inserted into the gas collecting cavity 36. The inner ring surface of the first mounting frame 1 is provided with air dispersion openings 37, and the air dispersion openings 37 communicate with the gas collecting cavity 36; the tube bundling groove 30 is a "U"-shaped groove. A plurality of hoop plates 32 are installed between the two side walls of the tube bundling groove 30 by screws for limiting the air delivery pipe 31. The bottom surface of the tube bundling groove 30 is provided with insertion holes 34, and the one-way valve head 33 is inserted into the insertion holes 34. A sealing ring 35 is fixed inside the insertion holes 34, and the sealing ring 35 is sleeved on the pipe body of the one-way valve head 33. The air dispersion openings 37 are "L"-shaped grooves, and there are a plurality of air dispersion openings 37, which are arranged equidistantly and equally in size along the long side of the gas collecting cavity 36. When in use, after a plurality of installation structures are assembled side by side, the air delivery pipe 31 is laid in the tube bundling grooves 30 of the plurality of installation structures. At this time, the one-way valve head 33 is inserted into the insertion holes 34. When the air delivery pipe 31 is connected to an air delivery device, the gas inside the air delivery pipe 31 is injected into the corresponding gas collecting cavity 36 through the one-way valve head 33, and the gas inside the gas collecting cavity 36 is blown out through the air dispersion openings 37 to blow off the covering leaves on the surface of the photovoltaic module body 46; thus, the second mounting frame 2 not only cooperates with the first mounting frame 1 to realize the clamping installation of the photovoltaic module body 46, but also realizes the function of removing leaves on the surface of the photovoltaic module body 46.

[0028] On one side of the top surface of the second mounting bracket 2, a splicing groove 38 is provided. On the other side of the second mounting bracket 2, a splicing plate 39 is fixed. A screw rod 41 is fixed on the surface of the splicing groove 38. The top end of the screw rod 41 is inserted with a long-handle screw rod II 44, which is used to connect the first mounting bracket 1 and the second mounting bracket 2. When two groups of mounting structures are arranged side by side, the splicing plate 39 of one group of mounting structures is inserted into the splicing groove 38 of the other group of mounting structures. The screw rod 41 penetrates through the splicing plate 39, and a nut is sleeved and screwed on the top end of the screw rod 41. The height of the splicing groove 38 is less than the height of the second mounting bracket 2. A through hole 40 is provided on the surface of the splicing plate 39 for the screw rod 41 to penetrate through the splicing plate 39. The thickness of the splicing plate 39 is less than the height of the splicing groove 38. The height of the screw rod 41 is equal to the height of the splicing groove 38; a reserved hole 42 is provided on the top surface of the screw rod 41. The reserved hole 42 is a "T"-shaped round hole. Screw holes 43 are provided on the surfaces of both the first mounting bracket 1 and the second mounting bracket 2. When the first mounting bracket 1 and the second mounting bracket 2 clamp the photovoltaic module body 46, the long-handle screw rod II 44 penetrates through the reserved hole 42 and the two screw holes 43; during use, when the two groups of mounting structures are assembled side by side, the splicing plate 39 is inserted into the corresponding splicing groove 38. At this time, the screw rod 41 passes through the through hole 40, and then the nut is sleeved and screwed on the screw rod 41 to fix the splicing plate 39 in the splicing groove 38, thereby realizing the connection of the two groups of mounting structures. At this time, there is no gap between the two groups of mounting structures, and the clamping block 11 used to fix the first mounting bracket 1 on the cross bar is also hidden under the splicing part of the two groups of mounting structures; it should be noted that when the first mounting bracket 1 and the second mounting bracket 2 clamp the photovoltaic module body 46, after the long-handle screw rod II 44 passes through the reserved hole 42, the long-handle screw rod II 44 is screwed into the screw hole 43 on the surface of the first mounting bracket 1, so that the long-handle screw rod II 44 connecting the first mounting bracket 1 and the second mounting bracket 2 is hidden in the screw rod 41, avoiding adding other protruding structures on the surfaces of the first mounting bracket 1 and the second mounting bracket 2. In this way, the screw rod 41 has multiple functions and is more functional; at this time, the second mounting bracket 2 not only realizes the installation of the photovoltaic module body 46 in cooperation with the first mounting bracket 1, but also satisfies blowing air on the surface of the photovoltaic module body 46 for impurity removal, and realizes the connection and fixation after two adjacent groups of mounting structures are arranged side by side, that is, the second mounting bracket 2 has multiple functions.

[0029] The use process of the photovoltaic module mounting structure is as follows: Place the photovoltaic module body 46 flat into the slot of mounting frame 1, ensuring that the edges of the module are aligned with the inner frame of the mounting frame. Close mounting frame 2, which closes through the hinge joint end, so that the two sets of mounting frames clamp the photovoltaic module body 46 (with the side groove 45 facing upwards for subsequent side-by-side splicing). Use both thumbs and index fingers to move the two side pull plates 17 towards the middle, causing the push plate 16 to move towards the stopper 9 and releasing the extrusion on the clamping block 11. The clamping block 11 partially extends out of the socket 10 under the elastic rebound of the rubber band 14, releasing the clamping on the rubber strip 7. Slide the sliding sleeve 5 along the guide rod 4 so that the bottom plate of the connecting plate 21 aligns with the crossbar of the photovoltaic support. Push the pull plate 17 outwards, and the push plate 16 squeezes the inclined surface of the clamping block 11, causing it to retract into the socket 10 and tension the rubber band 14. The clamping groove 12 of the clamping block 11 engages with the rubber strip 7 to brake the sliding sleeve 5 by friction. Fit the bottom plate of the connecting plate 21 to the crossbar, and screw the connecting screw 22 through the bottom plate and into the reserved hole of the crossbar. Adjust the distance between the two side clamping plates 19 so that they clamp both sides of the crossbar, and the rubber pads 29 provide anti-slip function. Screw the long handle screw 27 of the tightening turning handle 25 to make the clamping plate 19 closely fit the crossbar. Insert the air delivery pipe 31 into the beam pipe groove 30 of each mounting frame 2 in sequence and fix it with the hoop plate 32. Insert the one-way valve head 33 into the jack 34, and seal it with the sealing ring 35 to ensure that gas flows into the gas collecting chamber 36 unidirectionally. The end of the air delivery pipe 31 is connected to an air pump or a compressed air source. Turn on the air source and observe whether the one-way valve head 33 works properly, and the gas is evenly blown out through the air dispersing port 37. Insert the splicing plate 39 of a set of mounting structures into the splicing groove 38 of the adjacent structure, ensuring that the screw 41 passes through the through hole 40. Screw the nut to fix the splicing plate 39 to tightly connect the two sets of structures, and the side groove 45 houses the hinge to avoid gaps. Pass the long handle screw 44 through the reserved hole 42 at the top of the screw 41 and screw it into the screw holes 43 of the two sets of mounting frames for hidden fixing. Confirm that all connecting screws are tightened, the sliding sleeve 5 does not slide, and the air delivery pipe 31 does not leak air. Start the gas cleaning system, observe whether the air outlet at the air dispersing port 37 is uniform, and there is no obstruction on the surface of the photovoltaic module. Ensure that there are no gaps between the side-by-side mounting structures and at the side groove 45, and the splicing joints are flat. Modular design: Achieve rapid installation and expansion through the sliding sleeve-guide rod structure and the splicing groove / plate. Dual fixing mechanism: The connecting screw 22 + the clamping plate 19 achieve longitudinal anti-disengagement; the long handle screw 44 + the splicing groove 38 achieve horizontal seamless splicing. Gas cleaning integration: Utilize the gas collecting chamber 36 and the air dispersing port 37 of the mounting frame 2 to integrate the cleaning function; Hidden connection: The nested design of the screw 41 and the long handle screw 44 avoids protruding structures on the surface.
