Description

Technical Field

[0001] The 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] Double-glass photovoltaic modules refer to photovoltaic cell modules 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 photovoltaic 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. It is necessary to adopt a protective structure to provide severe weather protection for the photovoltaic modules.

[0024] The top rolling mechanism includes two L-shaped plates 21 symmetrically arranged on the outside of the battery housing 2, and a stopper plate 22 is fixedly installed at the bottom end of the L-shaped plate 21. The outside of the stopper plate 22 and the top of the movable plate 10 are both arc-shaped structures, so that when the stopper plate 22 contacts the movable plate 10, the movable plate 10 can push the L-shaped plate 21 to move through the stopper plate 22.

A slide bar 24 passes through the slide block 23, and a spring 25 is arranged on the outer side of the slide bar 24. The slide block 23 is pushed upward by the elasticity of the spring 25. The spring 25 is fixedly installed between the bottom of the slide block 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 outer side of the positioning rod 26.

A groove for the pressure roller 27 to limit the sliding of the pressure roller 27 is opened on the top of the storage motor housing 2, so as to facilitate the storage of the pressure roller 27. When the movable plate 10 moves back, the arc surface at 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 storage battery case 2 and the outer side of the sliding rod 24, compressing the spring 25, and the L-shaped plate 21 receives the pressure roller 27 into the groove of the storage 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, makes the hail pop out directly from the elastic coil 5 when falling, and increases the inclination angle of the elastic coil 5, so that the hail can slide down quickly, thereby achieving the effect of improving the rapid ice discharge.

[0025] Working principle: First, the user fixes the steel frame 1 on the lighting platform. When a harsh environment occurs, the driving motor 12 is started, and the driving 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 to provide 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, and pushes 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 fragments remaining on the top of the photovoltaic panel 3 when moving, so as to ensure the cleanliness of the surface of the photovoltaic panel 3. Since the moving plate 10 is 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 slider 24. The slider 23 pushes the positioning rod 26 to move 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 the hail can be directly ejected from the elastic coil 5 when falling, which is convenient for 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.

[0026] Example 2: Please refer to Figure 2 and Figure 5 This embodiment further explains Example 1. A mounting bracket 28 is fixedly installed at the bottom of the steel frame 1 in the figure. 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 storage battery casing 2 to provide protection for the storage 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 at 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.

[0027] In this embodiment: the inclined surface on 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.

[0028] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments. An arc scraper 2 30 is fixedly installed between the two movable plates 10 in the figure. The roller brush 15 is located between the arc scraper 1 20 and the arc scraper 2 30. The bottom of the arc 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 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 roll strip 5.

[0029] 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 and water cleaned out by the roller brush 15, thereby improving the cleanliness of the surface of the photovoltaic panel 3, and when the arc scraper 20 moves, the baffles 31 on both sides of the arc scraper 20 can prevent the pushed ice from returning to the inner side of the arc scraper 20, so as to push the ice out of the top of the photovoltaic panel 3, and the outer rubber pressure roller 27 can flexibly press the elastic curling strip 5 to provide protection for the elastic curling strip 5.
