Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of self-cleaning of the bottom edge of a solar photovoltaic panel, in particular to a sewage discharge device at the bottom edge of a photovoltaic panel made of stainless steel. Background Art
[0002] As distributed photovoltaic installation application scenarios become more differentiated and popularized, in order to maximize the utilization efficiency within a limited area, many photovoltaic panels are installed at an extremely low installation height angle. As the use time goes by and the pollution in the surrounding environment of the power station accumulates, a serious dust accumulation belt will form on the lower edge of the photovoltaic panel. The existence of this dust accumulation belt will lead to a decrease in the power generation of the photovoltaic system and the formation of hot spots on the photovoltaic panels, posing a great threat to the asset value preservation of the power station.
[0003] Therefore, it is necessary to develop a product with automatic sewage discharge effect to eliminate the adverse effects of dust accumulation. By utilizing the water flow on the surface of the photovoltaic panels during rainfall or cleaning, the dust accumulated on the bottom edge of the photovoltaic panels can be cleared from the surface of the photovoltaic panels in a timely and effective manner, thereby avoiding large power generation losses and hot spots that lead to asset impairment problems.
[0004] Therefore, it is necessary to provide a sewage discharge device at the lower edge of a photovoltaic panel made of stainless steel to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a sewage discharge device at the lower edge of a photovoltaic panel made of stainless steel.
[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0007] A sewage discharge device for the lower edge of a photovoltaic panel made of stainless steel comprises a top plate (1), wherein two arc-shaped stiffening ribs (3) are arranged in the middle of the top plate and extend backward from the front edge of the top cover to the bending point between the top cover and the vertical plate, so that the top cover of the sewage discharge device can be suspended as a whole; the arc-shaped stiffening ribs retain a chamfer with a smooth transition of the arc shape at the bending point, and extend downward from the rear edge of the top cover to the drainage end at the end of the vertical plate (2), so that the arc-shaped stiffening ribs are used as drainage strips to achieve full penetration from the water diversion end, the water guide section and the drainage end of the top cover, and an S-shaped reinforced bracket plate (4) is arranged in the middle of the drainage end at the end of the two arc-shaped stiffening ribs and can be tightly connected to the photovoltaic panel.
[0008] Furthermore, two arc-shaped stiffening ribs (3) are arranged in the middle of the top plate. The stiffening ribs extend backward from the front edge of the top cover to the bending point between the top cover and the vertical plate. After the sewage discharge device is installed in place, the top cover of the device can be suspended as a whole.
[0009] Furthermore, the arc-shaped stiffening rib retains an arc-shaped smooth transition chamfer at the bend. Through the smooth transition chamfer of the top cover and the vertical plate at the bend, the vortex problem after the water loss velocity at the bend is reduced, thereby ensuring the water flow velocity in the drainage channel passing through the bend.
[0010] Furthermore, the two arc-shaped stiffening ribs extend backward from the front edge of the top cover to the bend between the top cover and the vertical plate and extend downward through the bend to the drainage end at the end of the vertical plate (2). The arc-shaped stiffening ribs serve as drainage strips to achieve full penetration from the water diversion end, the water guide section and the drainage end of the top cover. The entire sewage route has a dead angle design, and combined with the fact that there is no bend at the bottom of the drainage end, the drainage speed can be ensured.
[0011] Furthermore, an S-shaped reinforced base plate is arranged between the drainage ends at the ends of the two arc-shaped stiffening ribs. Between the S-shaped reinforced base plate and the two full-length arc-shaped stiffening ribs of the top cover, greater bending stiffness and modulus are formed by relying on the material properties of the stainless steel itself and the two stiffening ribs protruding from the product plane, thereby ensuring anti-deformation performance, achieving a tight connection with the photovoltaic panel, and preventing falling off performance during long-term use.
[0012] Furthermore, the width of the S-shaped reinforced card base plate is 10 mm, and the S-shaped design can achieve more convenient sliding into the component frame when it is close to the component frame, and the S-shaped top surface and the bottom surface of the component bottom frame can be compacted after installation.
[0013] Compared with the prior art, the utility model utilizes the water flow on the surface of the photovoltaic panel during rainfall or cleaning to timely and effectively clear the dust accumulated on the bottom edge of the photovoltaic panel from the surface of the photovoltaic panel, thereby avoiding large power generation losses and hot spots that lead to asset impairment problems.

[0017] Example:
[0018] See also Figure 1-3The present embodiment is a sewage discharge device at the lower edge of a photovoltaic panel made of stainless steel, comprising a top plate 1, wherein two arc-shaped stiffening ribs 3 are arranged in the middle of the top plate, and the stiffening ribs extend backward from the front edge of the top cover to the bending point of the top cover and the vertical plate, so that the top cover of the sewage discharge device can be suspended as a whole; the arc-shaped stiffening ribs retain a smooth transition chamfer of an arc shape at the bending point, and extend downward from the rear edge of the top cover to the drainage end at the end of the vertical plate 2, thereby the arc-shaped stiffening ribs serve as drainage strips to fully penetrate the water diversion end, the water diversion section and the drainage end of the top cover, and an S-shaped reinforced card seat plate 4 is arranged in the middle of the drainage end at the end of the two arc-shaped stiffening ribs, which can be tightly connected with the photovoltaic panel.
[0019] Two arc-shaped stiffening ribs 3 are arranged in the middle of the top plate. The stiffening ribs extend backward from the front edge of the top cover to the bending point between the top cover and the vertical plate. After the sewage discharge device is installed in place, the top cover of the device can be suspended as a whole. This design scheme can ensure that there is enough sewage discharge space under the top cover, reducing the problem of clogging under the top cover during long-term use of similar products.
[0020] The arc-shaped stiffening rib retains a smooth transition chamfer at the bend. The smooth transition chamfer between the top cover and the vertical plate at the bend reduces the vortex problem after the water loss at the bend, ensuring the water flow speed in the drainage channel when passing through the bend.
[0021] The two arc-shaped stiffening ribs extend backward from the front edge of the top cover to the bending point between the top cover and the vertical plate and extend downward through the bending point to the drainage end at the end of the vertical plate 2. The arc-shaped stiffening ribs serve as drainage strips to achieve full penetration from the water diversion end, the water guide section and the drainage end of the top cover. The entire sewage route is designed without dead angles, and combined with the fact that there is no bend at the bottom of the drainage end, the drainage speed can be ensured.
[0022] An S-shaped reinforced base plate is arranged between the drainage ends at the ends of the two arc-shaped stiffening ribs. Between the S-shaped reinforced base plate and the two full-length arc-shaped stiffening ribs of the top cover, the material properties of the stainless steel itself and the two stiffening ribs protruding from the product plane form a greater bending stiffness and modulus, thereby ensuring anti-deformation performance, achieving a tight connection with the photovoltaic panel, and preventing falling off performance during long-term use.
[0023] An S-shaped reinforced base plate is set between the drainage ends at the ends of the two arc-shaped stiffening ribs, which fully considers the difficulty of the installation process of the completed power station. The width of the S-shaped reinforced base plate is 10mm. Combined with the S-shaped design, it can be more conveniently slid in when close to the component frame and the S-shaped top surface and the bottom surface of the component bottom frame can be compacted after installation.
[0024] Compared with the prior art, the utility model utilizes the water flow on the surface of the photovoltaic panel during rainfall or cleaning to timely and effectively clear the dust accumulated on the bottom edge of the photovoltaic panel from the surface of the photovoltaic panel, thereby avoiding large power generation losses and hot spots that lead to asset impairment problems.
[0025] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
