Description

Technical Field

[0001] The utility model belongs to the field of solar photovoltaic panel accessories, and particularly relates to a dust and water drainage clip for a solar photovoltaic panel. Background Technique

[0002] Solar photovoltaic power generation has unique advantages such as a large total exploitable amount, a wide distribution range, high safety and reliability, and no environmental pollution. With the continuous improvement of technology levels, it has become one of the fastest-growing renewable new energies. It is expected that the newly installed global photovoltaic capacity will reach 436 - 516 GW in 2030. In order to improve the power generation efficiency of solar photovoltaic panels, there is usually an optimal installation angle when installing the photovoltaic panels. Coupled with the fact that the component frames of the photovoltaic panels are all higher than the upper surface of the photovoltaic panels, this will cause water and dust to accumulate in the area 5 cm - 25 cm at the bottom of the photovoltaic panels with a smaller inclination angle. After the water evaporates, scale and mud belts will be formed, which will block the photovoltaic panels, affect the power generation efficiency of the photovoltaic panels, and will also damage the photovoltaic panels due to the hot spot effect and reduce the service life of the components.

[0003] Currently, for the water accumulation and strip-shaped dust accumulation on photovoltaic panels, a dust and water automatic cleaning device is mostly used. However, the water guiding channels of the existing dust and water cleaning devices are arranged on the inner wall of the dust and water automatic cleaning device, and the gap with the lower frame of the photovoltaic panel is used as the water guiding channel to drain the dust and water. The water guiding and draining channels are easily blocked, the drainage is not smooth, the drainage efficiency is low, and only the dust and water can be drained, and the formed scale and dust blocks cannot be removed, and the dust cleaning effect is not good. Moreover, the device has the problem of insecure installation and easy detachment. In view of the above problems existing in the prior art, it is urgent to improve the prior art to make up for the deficiencies of the prior art. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the design of the present utility model is to provide a dust and water drainage clip for a solar photovoltaic panel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model with reference to the drawings of the specification to better understand the technical solution.

[0018] A dust cleaning and water draining clip for a solar photovoltaic panel of the present utility model makes the water draining smooth and improves the water draining efficiency by designing a water guiding and draining terminal with a novel structure, has a good cleaning effect on the formed water scale and ash blocks by designing a dust cleaning hole, and adds triangular bottom clamping support points and triangular top clamping support points to the installation buckle, so that the installation buckle can be firmly clamped with the photovoltaic frame and is not easy to fall off after installation.

[0019] Its specific structure is as Figure 1-2 shown, including an installation buckle 1, a dust cleaning hole 2 and a drainage terminal 3. In order to facilitate the installation of the installation buckle, the installation buckle 1 is integrally formed and composed of a clamping top plate 4, a vertical plate 5 and a clamping bottom plate 6. In order to increase the stability of the installation and prevent falling off, 2 pairs of triangular bottom card support points 12 and angular top card support points 14 are respectively arranged on the clamping bottom plate 6 and the clamping top plate 4 to increase the stability of the installation. In order to further enhance the firmness of the installation clamping, a rolled-up reinforcement strip 13 is preferably arranged at the front end of the bottom of the clamping bottom plate 6.

[0020] In order to efficiently clean the water scale and ash blocks on the photovoltaic panel, a pair of dust cleaning holes 2 are symmetrically arranged on the left and right sides of the clamping top plate 4. The dust cleaning holes 2 form a direct through hole with the photovoltaic panel without any obstruction, and large water scale and ash blocks can be directly washed and removed by rainwater. The drainage terminal can drain the remaining accumulated water, and the siphon effect is used to make a part of the excess water drain through the dust cleaning holes 2, which can not only improve the drainage efficiency but also play a role in dust cleaning. In order to increase the strength of the dust cleaning holes 2, a dust cleaning hole reinforcing rib 16 is arranged on the upper part of the dust cleaning holes 2.

[0021] In order to improve the drainage efficiency of the accumulated water and prevent the drainage channel from being blocked, drainage terminals 3 connected to the dust cleaning holes 2 are symmetrically designed on both sides of the installation buckle in sequence. The drainage terminal 3 is composed of a water absorption end 7, a water guiding section 8 and a drainage end 9. A water guiding channel 17 is arranged on the inner walls of the water absorption end 7 and the water guiding section 8, and a drainage channel 10 is arranged on the inner wall of the drainage end 9. The water guiding channel 17 and the drainage channel 10 are communicated. Since an open drainage gap is formed between the drainage end 9 and the side of the photovoltaic panel, the drainage efficiency is increased and it is not easy to cause blockage. In order to prevent the water guiding channel 17 and the drainage channel 10 from being blocked by ash and affecting the drainage efficiency, a self-cleaning small hole 11 is preferably arranged on the upper part of the water guiding section 8 for self-cleaning of the water guiding channel 17 and the drainage channel 10 by the impact of rainwater.

[0022] The structure of this utility model patent is simple, convenient for installation and use. When in use, only need to clamp this device on the bottom frame of the solar photovoltaic panel through the installation buckle, and the functions of automatic drainage and dust cleaning can be realized.

[0023] The embodiments described above are only descriptions of the preferred modes of the present utility model, and do not limit the scope of this patent. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to this technical solution should fall within the protection scope determined by the claims of the present utility model.
