Description

Technical Field

[0001] The present invention relates to the field of double-glass photovoltaic modules, and in particular to a self-owned steel structure fixing device for double-glass photovoltaic modules. Background Art

[0002] A double-glass photovoltaic module refers to a photovoltaic cell module composed of a composite layer of two pieces of glass and solar cells. The cells are connected in series and in parallel by wires to the lead ends. Both sides of the module can collect sunlight, thereby increasing power generation. When sunlight shines, part of the light will be reflected by the surrounding environment to the back of the module. The double-sided module has the ability to collect this part of the light energy, thereby increasing power generation. It is suitable for various environments that require efficient use of solar energy, such as glass curtain walls, building roofs, solar water heaters, agricultural greenhouses, etc.

[0003] Double-glass photovoltaic modules are often used outdoors. When encountering severe weather such as hail, the photovoltaic modules may be damaged by explosion. A protective structure is needed to provide protection for the photovoltaic modules from severe weather. The existing Chinese patent document: CN116846318A discloses a self-contained steel structure fixing device for double-glass photovoltaic modules. By setting up a protective mechanism, the photovoltaic modules on the second mounting plate can be moved to the inner wall of the protective plate for protection, thereby avoiding damage to the photovoltaic modules in severe hail weather. However, when hail has fallen, the hail will be stuck between the mounting plate and the protective plate, pushing the photovoltaic module with the mounting plate to move, causing the hail to rub against the surface of the photovoltaic module, squeezing the glass plate on the photovoltaic module. When the hail is large in size, the glass will be crushed, causing greater damage and lower safety. Summary of the Invention

One end of the elastic coil 5 extends to the top of the battery housing 2. When the elastic coil 5 covers the top of the photovoltaic panel 3, it can provide protection for the top of the photovoltaic panel 3. A fixed strip 9 is fixedly mounted on the end of the elastic coil 5 away from the winding box 4, and a movable plate 10 is fixedly mounted on both ends of the fixed strip 9.

A drive motor 12 is fixedly installed on the bottom of the battery housing 2. A transmission belt 13 is rotatably installed between the output end of the drive motor 12 and the two screws 8. When the drive motor 12 is running, the two screws 8 can be driven to rotate synchronously through the transmission belt 13 to achieve stretching of the elastic coil 5. A cavity is opened inside the battery housing 2 for installing the transmission belt 13 and the drive motor 12.

[0032] When the driving motor 12 is running, it can drive the two screws 8 to rotate synchronously through the transmission belt 13, so that the screw 8 drives the moving block 11 to move along the inner side of the guide frame 7, and the moving block 11 drives the fixed bar 9 to move synchronously through the moving plate 10, so that the fixed bar 9 pulls one end of the elastic coil 5 out of the winding box 4, and as the moving block 11 moves, the elastic coil 5 covers the top of the photovoltaic panel 3, providing protection for the top of the photovoltaic panel 3, solving the problem that the photovoltaic panel 3 is easily squeezed by hail when moving, thereby achieving the effect of safety protection.

A rack plate 19 that cooperates with the gear 18 is fixedly installed at the bottom of the long groove of the fixed frame 6. When the movable plate 10 moves, it can drive the gear 18 on the driven rod 16 to move along the surface of the rack plate 19. An arc-shaped scraper 20 is fixedly installed at the bottom of the fixed bar 9. The side of the arc-shaped scraper 20 close to the roller brush 15 is concave to prevent ice debris from accumulating. The bottom of the arc-shaped scraper 20 contacts the top of the photovoltaic panel 3, which is convenient for quickly pushing out the larger ice debris on the surface of the photovoltaic panel 3;

[0034] When the movable plate 10 moves, it can drive the mounting rod 14, the driven rod 16 and the arc scraper 20 to move synchronously. The arc scraper 20 can move along the top of the photovoltaic panel 3 to push out large pieces of ice debris from the top of the photovoltaic panel 3. The driven rod 16 drives the gear 18 to move along the surface of the rack plate 19 to realize the self-rotation of the driven rod 16. The driven rod 16 drives the mounting rod 14 to rotate through the synchronous belt 17, so that the mounting rod 14 drives the roller brush 15 to rotate.

It can also achieve the cleaning of the top of the photovoltaic panel 3 and improve the durability of the photovoltaic panel 3.

[0035] The top rolling mechanism includes two L-shaped plates 21 symmetrically arranged on the outside of the battery case 2. The bottom end of the L-shaped plate 21 is fixedly installed with a support plate 22. The outer side of the support plate 22 and the top of the movable plate 10 are both arc-shaped structures, so that when the support plate 22 contacts the movable plate 10, the movable plate 10 can push the L-shaped plate 21 to move through the support plate 22. A slider 23 is fixedly installed on the side of the L-shaped plate 21 close to the battery case 2. A sliding cavity is opened on the outside of the battery case 2 for the slider 23 to slide in a limited position. A sliding cavity is fixedly installed on the inside of the sliding cavity of the battery case 2. A slide rod 24 passes through the slider 23, and a spring 25 is provided on the outside of the slide rod 24. The elasticity of the spring 25 is used to push the slider 23 upward. The spring 25 is fixedly installed between the bottom of the slider 23 and the bottom inner wall of the slide cavity. A positioning rod 26 is fixedly installed between the two L-shaped plates 21. A pressure roller 27 is rotatably installed on the outside of the positioning rod 26. The pressure roller 27 pushes the bottom of the elastic coil 5 to prop up the elastic coil 5. A groove is provided on the top of the accumulator housing 2 for the pressure roller 27 to limit the sliding of the pressure roller 27, which is convenient for storing the pressure roller 27.

[0036] When the movable plate 10 moves back, the arc surface of the bottom of the movable plate 10 can contact the arc surface of the abutting plate 22, so that the movable plate 10 pushes the abutting plate 22 to move, and the abutting plate 22 pulls the slider 23 on the L-shaped plate 21 to move downward along the sliding cavity of the battery case 2 and the outer side of the slide rod 24, compressing the spring 25, and the L-shaped plate 21 retracts the pressure roller 27 into the groove of the battery case 2 through the positioning rod 26. When the movable plate 10 moves away from the abutting plate 22, the rebound force of the spring 25 can push the slider 23 to make the L-shaped plate 21 push the positioning rod 26 to move upward, so that the pressure roller 27 lifts the bottom of the elastic coil 5, realizes the tensioning of the elastic coil 5, ensures the elasticity of the elastic coil 5, so that the hail can be directly ejected from the elastic coil 5 when falling, and increases the inclination angle of the elastic coil 5, which is convenient for the hail to slide down quickly, thereby achieving the effect of improving the rapid ice discharge.

[0037] Working principle: First, the user fixes the steel frame 1 on the lighting platform. When a harsh environment occurs, the drive motor 12 is started, and the drive motor 12 drives the two screws 8 to rotate synchronously through the transmission belt 13, so that the screw 8 drives the moving block 11 to move along the inner side of the guide frame 7, and the moving block 11 drives the fixed bar 9 to move synchronously through the moving plate 10. At this time, the fixed bar 9 pulls one end of the elastic coil 5 out of the winding box 4 and moves toward the bottom end of the photovoltaic panel 3, so that the elastic coil 5 covers the top of the photovoltaic panel 3, providing protection for the top of the photovoltaic panel 3. At the same time, the moving block 11 drives the mounting rod 14 and the driven rod 16 to move synchronously, and the fixed bar 9 and the arc scraper 20 move synchronously, so that the arc scraper 20 moves along the top of the photovoltaic panel 3, pushing large pieces of ice debris out of the top of the photovoltaic panel 3. At the same time, the driven rod 16 drives the gear The wheel 18 moves along the surface of the rack plate 19 to realize the self-rotation of the driven rod 16. The driven rod 16 drives the mounting rod 14 to rotate through the synchronous belt 17, so that the mounting rod 14 drives the roller brush 15 to rotate. The roller brush 15 can clean the water and small ice debris remaining on the top of the photovoltaic panel 3 when moving, thereby ensuring the cleanliness of the surface of the photovoltaic panel 3. Since the movable plate 10 moves away from the abutment plate 22 when moving, the rebound force of the spring 25 is used to push the slider 23 to move upward along the outer side of the slide rod 24. The slider 23 pushes the positioning rod 26 upward through the L-shaped plate 21, so that the pressure roller 27 lifts the bottom of the elastic coil 5 and stretches the elastic coil 5, so that hail can be directly ejected from the elastic coil 5 when falling, which facilitates the hail to slide down quickly, thereby achieving the effect of safety protection and cleaning and de-icing, and improving the durability of the photovoltaic panel 3.

[0038] Example 2: Please refer to Figure 2 and Figure 5 This embodiment further explains Example 1. The bottom of the steel frame 1 in the figure is fixedly installed with a mounting bracket 28. The mounting bracket 28 is a frame-shaped structure, which is convenient for light to irradiate the bottom of the photovoltaic panel 3. A sealing shell 29 is fixedly installed at the bottom of the cavity of the battery casing 2 to provide protection for the battery casing 2 and facilitate disassembly and maintenance. The top of the steel frame 1 is a right-angled triangular plate structure. The inclined surface of the top of the steel frame 1 is fixedly connected to the bottom of the fixed frame 6 to provide support for the bottom of the fixed frame 6.

[0039] In this embodiment: the inclined surface at the top of the steel frame 1 can facilitate the installation and positioning of the fixed frame 6, so that the fixed frame 6 can provide support and protection for the inclined photovoltaic panel 3, which is convenient for assembly; the mounting bracket 28 can provide support for the bottom of the steel frame 1, and the mounting bracket 28 with a frame-shaped structure facilitates light to illuminate the bottom of the photovoltaic panel 3, preventing obstruction and ensuring the normal use of the bottom of the photovoltaic panel 3; the sealing shell 29 can provide protection for the drive motor 12 and facilitate disassembly and maintenance.

[0040] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments. An arc-shaped scraper 2 30 is fixedly installed between the two movable plates 10 in the figure. The roller brush 15 is located between the arc-shaped scraper 1 20 and the arc-shaped scraper 2 30. The bottom of the arc-shaped scraper 2 30 contacts the top of the photovoltaic panel 3 to clean the residual ice debris. Baffles 31 are fixedly installed at both ends of the arc-shaped scraper 1 20 to facilitate pushing out the ice debris on the top of the photovoltaic panel 3. The outer side of the pressure roller 27 is made of rubber material to flexibly press the elastic coil 5.

[0041] In this embodiment: when the movable plate 10 moves, it can drive the arc scraper 2 30 to move synchronously along the top of the photovoltaic panel 3, so as to push out the small pieces of ice debris and water cleaned by the roller brush 15, thereby improving the cleanliness of the surface of the photovoltaic panel 3, and when the arc scraper 1 20 moves, the baffles 31 on both sides of the arc scraper 1 20 can prevent the pushed ice debris from returning to the inner side of the arc scraper 1 20, so as to facilitate pushing the ice debris out of the top of the photovoltaic panel 3, and the outer rubber pressure roller 27 can flexibly press the elastic roll strip 5 to provide protection for the elastic roll strip 5.
