Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic battery panels, in particular to a protective structure for photovoltaic power generation. Background Art

[0002] The surface protection structure of a solar photovoltaic panel is a crucial component of a photovoltaic system. Its structure mainly includes a covering layer made of wear-resistant and corrosion-resistant materials, such as glass, polycarbonate or special coatings, to protect the surface of the panel from mechanical damage and external environmental influences. These structures are tightly integrated with the photovoltaic panel to form a whole, ensuring high transparency and optical quality to promote effective absorption of light. However, at present, the surface protection structure of a solar panel generally needs to be pre-set and processed according to the length and width of the panel. After the solar photovoltaic panel and the bracket are installed, the pre-processed surface protection structure is installed on the panel frame or bracket. It is difficult to use it on existing and arranged solar photovoltaic panels. That is, the sizes and shapes of solar photovoltaic panels vary, and the pre-set surface protection structure is difficult to match the shape and size of each panel. This leads to a significant increase in the use cost and layout cost of the protection structure. Utility Model Content

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-4 The utility model provides an embodiment: a protective structure for photovoltaic power generation, comprising a square linear profile 1 and a convex double-layer plywood 3 slidably mounted on the outer wall of one side of the square linear profile 1, and an X-axis horizontal plate 4 is fixed to the bottom end of the convex double-layer plywood 3, and a screw rod pushing structure 2 for driving the convex double-layer plywood 3 and the X-axis horizontal plate 4 to move along the extension line direction of the square linear profile 1 is installed on the outer wall of the other side of the square linear profile 1, a plate frame clamping structure 10 is installed at the bottom end of the square linear profile 1, a glass plate 5 is installed on the outer wall of the side of the convex double-layer plywood 3 away from the square linear profile 1, an X-axis horizontal plate 4 is fixed to the bottom end of the convex double-layer plywood 3, and a glass plate 2 8 is slidably mounted on the outer wall of the side of the X-axis horizontal plate 4 close to the convex double-layer plywood 3;

[0018] The plate-frame clamping structure 10 includes a Y-axis C-mount frame 1001 welded to the bottom end of the square linear profile 1. A threaded pin 1002 is threadedly installed on the bottom end of the Y-axis C-mount frame 1001, and a rubber disc 1003 is installed on the top end of the threaded pin 1002. The staff clamps the Y-axis C-mount frame 1001 on the side of the battery frame and then continuously screws the threaded pin 1002 so that the threaded pin 1002 drives the rubber disc 1003 against the bottom end of the battery frame, thereby completing the installation operation of the protective structure. It can more firmly fix the protective structure on the battery panel frame and reduce the risk of loosening or falling off in adverse weather conditions such as wind and rain.

[0019] The screw pushing structure 2 includes two right-angled shaft seats 201 fixed on the outer wall of one side of the square linear profile 1, and a threaded shaft 202 rotatably installed between the two right-angled shaft seats 201, a nut sleeve 203 is installed at the threaded part of one end of the surface of the threaded shaft 202, and a T-plate 204 is fixed to the top of the nut sleeve 203, and one end of the T-plate 204 is fixedly connected to the top of the convex double-layer splint 3. By rotating the threaded shaft 202, the threaded shaft 202 drives the nut sleeve 203, the T-plate 204 and the convex double-layer splint 3, the X-axis horizontal plate 4, the glass plate 1 5, the glass plate 2 8 and other components to slide until the glass plate 1 5 covers the column battery panel surface. By adjusting the position of the glass plate 1 5 through the screw pushing structure 2, it can be ensured that the glass plate 1 5 and the glass plate 2 8 will no longer slide after moving;

[0020] A dovetail groove is provided on the outer wall of one side of the X-axis horizontal plate 4, and a dovetail slide plate 7 is slidably installed inside the dovetail groove. One side of the dovetail slide plate 7 is fixedly connected to one side of the second glass plate 8. A supporting piece 11 is fixed to one end of the square linear profile 1 close to the convex double-layer plywood 3, and a cutting groove 1101 with the same gap as the thickness of the second glass plate 8 is provided inside the supporting piece 11. The second glass plate 8 is manually pulled so that the second glass plate 8 slides relative to the X-axis horizontal plate 4 through the dovetail slide plate 7. During this process, the supporting piece 11 and the Y-axis C-mouth frame 1001 are used to support the second glass plate 8 and improve the sliding stability of the second glass plate 8, ensuring that the glass plate remains stable during movement;

[0021] An F-shaped rubber strip 6 and a rubber strip 2 9 are fixed to the same side of the glass plate 1 5 and the glass plate 2 8, respectively. The F-shaped rubber strip 6 and the rubber strip 2 9 are slidably matched, and the same side of the glass plate 1 5 and the glass plate 2 8 slide relative to each other through the F-shaped rubber strip 6 and the rubber strip 2 9. When external impact or vibration acts on the glass plate or the solar photovoltaic system, the rubber strip can absorb part of the energy and reduce the impact on the glass plate and the solar panel.

[0022] When the embodiment of the present application is in use, the staff first takes out the protective structure, so that the square linear profile 1 is fixed on the metal frame of the solar photovoltaic panel through the plate frame clamping structure 10. At this time, the glass plate 1 5 and the glass plate 2 8 are all covered and located on the surface of the solar photovoltaic panel. Then the staff drives the convex double-layer splint 3, the X-axis horizontal plate 4, the dovetail slide plate 7 and other components to move through the screw pushing structure 2 until the glass plate 1 5 is blocked above the surface of the solar photovoltaic panel. After the position of the glass plate 1 5 is debugged, the staff manually pulls the glass plate 2 8 again, so that the glass plate 2 8 slides relative to the X-axis horizontal plate 4 through the dovetail slide plate 7, and then the glass The combined length of the first plate 5 and the second glass plate 8 is changed until the combined length of the two is roughly consistent with the length of the surface of the solar photovoltaic panel. The first glass plate 5 and the second glass plate 8 are used to protect the surface of the panel to reduce damage to the surface caused by external dust, sand and stones. Compared with the pre-setting and processing method, this structure does not need to be customized for each panel, and a sliding and extendable glass plate is set to protect the panel surface to adapt to solar panels of different specifications and sizes. The installer can adjust the position and size of the glass plate according to actual conditions so that it completely covers the surface of the panel, effectively simplifying the production and installation process of the protective structure and improving the adaptability of the structure.
