[0033] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0034] As mentioned in the above background art, the photovoltaic glass plate needs to be cleaned before and after being encapsulated into a module to remove impurities such as dust, dirt, and grease on the glass surface, so as to ensure the encapsulation quality and power generation efficiency of the photovoltaic module. Usually, the photovoltaic glass plate needs to be placed on the fixture of the cleaning equipment, and then the photovoltaic glass is cleaned by the cleaning equipment of the cleaning equipment. However, during the process of cleaning the photovoltaic glass plate, it is usually necessary to adjust the height and angle of the photovoltaic glass plate on the cleaning equipment to ensure the cleaning effect and facilitate the staff to check the cleaning effect. Therefore, the inventors of the present application provide a gantry of a photovoltaic glass plate cleaning machine and a photovoltaic glass cleaning machine in one or more embodiments. The gantry is rotatably connected to the mounting plate through the mounting frame, realizing the rotation of the photovoltaic glass plate, thereby adjusting the angle of the photovoltaic glass plate; through the movement of the mounting plate in the vertical direction, the adjustment of the height of the photovoltaic glass plate is realized, further ensuring the cleaning effect and facilitating the staff to check the cleaning effect. Thus, one or more problems in the prior art are solved.

[0035] In view of the above-mentioned technical problems, the present utility model provides a gantry of a photovoltaic glass plate cleaning machine, as Figures 1 - 4 shown, comprising: a bracket 1; the bracket 1 includes a bottom plate 2, two side plates 3 and two top plates 4. The bottom parts of the two side plates 3 are respectively connected to opposite sides of the bottom plate 2, and the two top plates 4 are respectively connected to the tops of the two side plates 3; a guide rod group 5, the guide rod group 5 includes two, and the bottom ends of the two guide rod groups 5 are both connected to the bottom plate 2, and their top ends are respectively connected to the two top plates 4; a mounting plate 6, the two ends of the mounting plate 6 are respectively connected to the two guide rod groups 5 and can move in the vertical direction; a mounting frame 7 for mounting the photovoltaic glass plate 21 is rotatably connected to the mounting plate 6; a driving mechanism 8, the driving mechanism 8 is arranged on the bottom plate 2, and its driving end is connected to the bottom surface of the mounting plate 6 to drive the mounting plate 6 to move in the vertical direction.

[0036] Specifically, when the photovoltaic glass plate cleaning machine is working, first, the photovoltaic glass plate 21 is installed on the installation frame 7. Then, the cleaning liquid is sprayed on the photovoltaic glass plate 21 through the cleaning mechanism (such as a cleaning nozzle) of the cleaning machine. Then, the surface of the photovoltaic glass is scraped by a scraping mechanism such as a squeegee, thereby realizing the cleaning of the photovoltaic glass plate 21. Specifically, both ends of the squeegee are slidably connected to two opposite side frames 15 of the installation frame 7 respectively, and the squeegee sweeps across the surface of the photovoltaic glass plate 21 during the sliding process. To facilitate the operation of the staff, when it is necessary to adjust the height of the photovoltaic glass, the driving mechanism 8 drives the mounting plate 6 to move in the vertical direction, thereby realizing the adjustment of the height of the photovoltaic glass plate 21. Specifically, the driving mechanism 8 can be a cylinder, and the cylinder is installed on the bottom plate 2, and its driving end is connected to the bottom surface of the mounting plate 6. To facilitate the inspection of the cleaning effect, when it is necessary to adjust the angle of the photovoltaic glass plate 21, the rotation of the installation frame 7 on the mounting plate 6 realizes the adjustment of the angle of the photovoltaic glass plate 21.

[0037] Furthermore, a locking mechanism can also be provided on the mounting plate 6. When the angle of the photovoltaic glass plate 21 is adjusted to the cleaning station or the inspection station, the installation frame 7 can be locked on the mounting plate 6 through the locking mechanism to prevent the installation frame 7 from rotating by itself and affecting the normal operation of the cleaning machine. Specifically, two vertical plates 20 are provided at opposite ends of the mounting plate 6, and opposite ends of the installation frame 7 are rotatably connected to the tops of the two vertical plates 20 through rotating shafts. The locking mechanism can be a telescopic rod with a self-locking function. One end of the telescopic rod is connected to the side frame 15 of the installation frame 7, and the other end is connected to the vertical plate 20. In addition, the guiding rod group 5 ensures that the mounting plate 6 can move stably in the vertical direction. Through the connection of the guiding rod group 5 with the bottom plate 2 and the top plate 4, and the connection of the bottom plate 2 and the top plate 4 through the side plate 3, the stability of the overall structure of the bench is ensured.

[0038] Compared with the prior art, the bench of a photovoltaic glass plate cleaning machine of the present application realizes the rotation of the photovoltaic glass plate 21 by rotatably connecting the installation frame 7 to the mounting plate 6, thereby adjusting the angle of the photovoltaic glass plate 21; through the movement of the mounting plate 6 in the vertical direction, the adjustment of the height of the photovoltaic glass plate 21 is realized, thereby ensuring the cleaning effect and facilitating the staff to inspect the cleaning effect.

[0039] In some embodiments, such as Figure 1 and Figure 2As shown, each guiding rod group 5 respectively includes two vertical rods 9. The bottom ends of the vertical rods 9 are connected to the bottom plate 2, and the top ends thereof are connected to the top plate 4. The corners of the mounting plate 6 are movably connected to the vertical rods 9 in the vertical direction. Specifically, the vertical rods 9 can be screws, and nuts can be arranged on the screws. The nuts are located below the mounting plate 6. After the mounting plate 6 moves into place, the nuts are screwed on the screws so that the nuts abut against the lower surface of the mounting plate 6, which plays a role in assisting the support of the mounting plate 6 and avoids the problem of unreasonable force caused by only the driving mechanism 8 supporting the mounting plate 6. In addition, the guiding rod group 5 composed of two vertical rods 9 ensures the rationality of the force and the stability of the movement of the mounting plate 6 during the movement process.

[0040] In some embodiments, as Figure 1 and Figure 2 shown, the bench further includes a buffer 10. The buffer 10 is arranged on the bottom plate 2, and the top end thereof is connected to the bottom surface of the mounting plate 6. During the up and down movement of the mounting plate 6, the buffer 10 plays a certain role in restricting the moving speed of the mounting plate 6, avoiding the problem that the mounting plate 6 moves too fast and damages the photovoltaic glass plate 21 on the mounting frame 7. Further, there can be multiple buffers 10, and the multiple buffers 10 are evenly distributed on the bottom plate 2, thereby ensuring the balance of the buffering force of the mounting plate 6 received by the buffers 10. Specifically, the buffer 10 can adopt a spring, and the spring should have a suitable elastic modulus, which not only ensures the buffering effect on the mounting plate 6 but also avoids affecting the movement of the mounting plate 6 in the vertical direction. For example, if the elastic modulus of the spring is too large, it may cause the driving mechanism 8 to be unable to drive the mounting plate 6 to move; if the elastic modulus of the spring is too small, it may cause the buffer 10 to have no buffering effect on the mounting plate 6. The specific numerical range of the elastic modulus needs to be calculated based on the weights of the mounting plate 6, the mounting frame 7, and the photovoltaic glass plate 21 carried thereon.

[0041] In some embodiments, as Figure 1 and Figure 2 shown, a detachable water collecting tank 11 is arranged on the bottom of the mounting frame 7. By arranging the water collecting tank 11, the cleaning solution on the photovoltaic glass plate 21 can flow down along the surface of the photovoltaic glass plate 21 into the water collecting tank 11 and be collected, avoiding the problem that the cleaning solution after cleaning flows into the environment and pollutes the environment.

[0042] In some embodiments, as Figure 2 shown, a detachable drain pipe 12 can be connected to the water collecting tank 11. Through the drain pipe 12, the cleaning solution after cleaning can be discharged from the collecting tank, avoiding the problem of overflow caused by the collecting tank being filled with the cleaning solution. At the same time, through the drain pipe 12, the cleaning solution after cleaning can be discharged into the recycling device, and through the filtration treatment of the recycling device, it can be reused, thereby reducing the operating cost and achieving energy conservation and emission reduction.

[0043] In some embodiments, as Figure 1 and Figure 5 shown, a fixing member 13 for fixing the photovoltaic glass plate 21 is provided on the frame 15 of the mounting frame 7. Specifically, a plurality of fixing members 13 are included, and the plurality of fixing members 13 are evenly distributed on the frame 15. The photovoltaic glass plate 21 can be fixed on the mounting frame 7 through the plurality of fixing members 13. Specifically, a fixture can be used, and the edge of the photovoltaic glass plate 21 is clamped together with the frame 15 through the fixture.

[0044] In some embodiments, as Figure 1 shown, a handle 14 for driving the mounting frame 7 to rotate is provided on the frame 15. The handle 14 facilitates the operation of the staff to rotate the mounting frame 7.

[0045] In some embodiments, as Figure 6 and Figure 7 shown, the frame 15 includes a first part 16 and a second part 17. The first part 16 and the second part 17 form an L-shaped groove 18 for installing the edge of the photovoltaic glass plate 21. The fixing member 13 is rotatably connected to the first part 16 for fixing the photovoltaic glass plate 21 on the mounting frame 7 or releasing it from the mounting frame 7. Through the L-shaped groove 18 and the rotation of the fixing member 13, the disassembly and assembly of the photovoltaic glass plate 21 on the mounting frame 7 are realized. Specifically, the fixing member 13 includes a retaining piece, and the retaining piece is rotatably connected to the top surface of the first part 16. After the edge of the photovoltaic glass plate 21 is placed in the L-shaped groove 18, the retaining piece is rotated so that the retaining piece abuts against the surface of the photovoltaic glass plate 21, thereby fixing the photovoltaic glass plate 21 on the mounting frame 7. After the cleaning of the photovoltaic glass plate 21 is completed, the retaining piece can be rotated away from the surface of the photovoltaic glass plate 21, so that the photovoltaic glass plate 21 can be removed from the mounting frame 7. Further, a threaded hole can be opened on the retaining piece, and one end of the fixing bolt is passed through the threaded hole and abuts against the surface of the photovoltaic glass plate 21 in the L-shaped groove 18, thereby realizing the fixation of glasses with different thicknesses in the L-shaped groove 18 and improving the application range of the bench. Specifically, a rubber pad is provided at the abutting end of the bolt and the photovoltaic glass plate 21 to avoid the problem of the bolt damaging the photovoltaic glass plate 21.

[0046] In some embodiments, as Figure 7 shown, elastic pads 19 are provided on the side wall and the bottom wall of the L-shaped groove 18. The elastic pads 19 protect the photovoltaic glass plate 21 and avoid the problem of the frame 15 scratching and abrading the edge of the photovoltaic glass plate 21.

[0047] On the other hand, the present application also provides a cleaning machine for photovoltaic glass plates, including the bench of the cleaning machine for photovoltaic glass plates described above.

[0048] In summary, compared with the prior art, the present disclosure provides a gantry for a photovoltaic glass plate cleaning machine and a photovoltaic glass plate cleaning machine. The gantry is rotatably connected to the mounting plate 6 through the mounting frame 7, realizing the rotation of the photovoltaic glass plate 21, thereby adjusting the angle of the photovoltaic glass plate 21. Through the vertical movement of the mounting plate 6, the height adjustment of the photovoltaic glass plate 21 is realized, thus ensuring the cleaning effect and facilitating the inspection of the cleaning effect by the staff; through the guide rod group 5 composed of two vertical rods 9, the rationality of the force and the stability of the movement of the mounting plate 6 during the movement are ensured; the photovoltaic glass is protected by the buffer 10 and the elastic pad 19; the recovery of the cleaning solution after cleaning is realized through the water collecting tank 11 and the drain pipe 12; the installation of the photovoltaic glass plate 21 on the mounting frame 7 is realized through the fixing member 13 and the L-shaped groove 18.
