Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation equipment technology, and more specifically to a fixing device for solar photovoltaic panels. Background Technology

[0002] Solar photovoltaic power generation, as a clean energy source, is being used more and more widely. Securely and reliably installing solar panels in various environments is fundamental to ensuring long-term, high-efficiency power generation. However, traditional fixing methods encounter various problems in practical applications. Common installation clamps, such as simple metal blocks and bolts, sometimes experience loosening or reduced clamping force under long-term exposure to wind, sun, thermal expansion and contraction, and potential vibrations. When the device is installed on a slope or during seasonal changes, the angle of the solar panels needs to be adjusted to meet sunlight requirements; traditional fixing methods make angle adjustments difficult. In cold, snowy regions, snow covering the photovoltaic panels severely hinders power generation; traditional cleaning methods often rely on manual labor, which is costly and risky. In strong winds, the wind can directly impact the panel surface, potentially causing physical damage or increasing the burden on the support structure, ultimately damaging the entire device. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: a solar photovoltaic panel is initially fixed in position by the wedge-shaped surfaces of a movable clamping plate and a fixed clamping plate. When the limiting block and the locking plate are pushed out by the limiting spring and the locking spring, the solar panel is fixed in place to prevent loosening and falling during operation. Rotating the handle drives the transmission gear through the transmission shaft, causing the transmission rack to move laterally. The sliding block slides on the protective plate, causing the protective plate to change angle. When the device is fixed at different slopes, the angle of the protective plate can be adjusted by rotating the handle to meet the solar panel's illumination requirements. The airflow is directed to the fan blades via the deflector on the protective plate, causing the blades to rotate. Through the transmission column, pulley, and belt, the driven gear rotates via gear meshing, which in turn drives the transmission screw, causing the snow scraper to slide. When snow accumulates on the solar panel, it is scraped off, effectively cleaning the solar panel. By incorporating ventilation holes and deflectors in the protective plate, the airflow is guided towards the fan blades on both sides, preventing damage from strong winds and allowing the airflow to effectively utilize the wind power.

[0010] (III) Beneficial Effects

[0011] (i) The solar panel is initially fixed in position by the wedge-shaped surfaces of the movable clamp and the fixed clamp. After the limiting block and the locking plate are pushed out by the limiting spring and the locking spring, the solar panel is fixed around the perimeter to fix the solar panel and prevent it from loosening and falling off during operation.

[0012] (ii) By rotating the handle, the transmission shaft drives the transmission gear to rotate, causing the transmission rack to move laterally. The transmission rack drives the support column, and the sliding block slides on the protective plate, causing the protective plate to change angle. When the device is fixed at different slopes, the angle of the protective plate can be adjusted by rotating the handle to meet the solar panel's illumination requirements.

[0013] (iii) The air is directed to the fan blades through the guide plate of the protective plate, causing the fan blades to rotate. Through the transmission column, the drive bevel gear rotates under the transmission pulley and transmission belt. The gear meshing drives the driven gear to rotate, thereby driving the transmission screw, causing the snow scraper to slide. When there is snow on the solar panel, the snow is scraped off, achieving the effect of cleaning the solar panel.

[0014] (iv) By setting ventilation holes and deflectors on the protective plate, when the wind passes through, the wind is guided by the deflectors to the fan blades arranged on both sides, so as to prevent the solar panel from being directly blown by the wind when the wind is too strong and causing damage. It can also guide the wind to blow the fan blades to achieve the effect of utilizing wind power. Attached Figure Description

The outer wall of the bottom of the mounting plate 310 is rotatably connected to the inner wall of the top of the bracket 1. When in use, the bracket 310 will be installed in a way that requires a positioning plate 316. The installed solar panel presses down the limiting block 318 along the mounting plate 310, causing the limiting spring 317 to retract. A locking spring 315 is fixedly connected to the outer wall of the locking plate 316. The end of the locking spring 315 away from the locking plate 316 is fixedly connected to the outer wall of the mounting plate 310. Simultaneously, the locking plate 316 is also pressed down, causing the locking spring 315 to retract.

This is to adjust the angle of the solar panel. When the device is installed on different slopes, it is necessary to adjust the angle according to the slope to meet the sunlight requirements of the solar panel.

The outer wall of the fixed clamping plate 314 is fixedly connected to the outer wall of the mounting plate 310. The solar panel slides... The fixed clamp 314, with its wedge-shaped surface, repositions the solar panel. Once the solar panel is in place, the limiting spring 317 extends, pushing out the limiting block 318, which prevents the solar panel from sliding. The locking spring 315 extends, pushing out the locking plate 316, which then limits and fixes the top of the solar panel. The solar panel installation is now complete.

When the device is installed on different slopes, a certain angle needs to be adjusted according to the slope to meet the sunlight requirements of the solar panel. When wind blows towards the protective plate 320, the wind passes through the ventilation hole 321 and then blows along the guide plate 322 to both sides of the protective plate 320.
