It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0021] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0022] Embodiment 1:
[0023] Combination Figure 1-5 As shown, this embodiment provides a photovoltaic component waterproof installation structure, including: a main body module 100.
[0024] Among them, the main body module 100 includes a T-shaped bracket 110, a first sealing strip 120 symmetrically embedded on both sides of the top of the T-shaped bracket 110, a T-shaped plate 130 with the bottom end embedded in the T-shaped bracket 110, a second sealing strip 140 symmetrically embedded on both sides of the bottom end of the T-shaped plate 130, a bolt 150 passing through the T-shaped bracket 110 and engaged in the T-shaped plate 130, a shell 160 fixed at the top of the T-shaped plate 130, a tube body 170 installed at the top of the shell 160 and connected to the inner cavity of the shell 160, a high-speed fan 180 installed on the inner wall of the tube body 170, and a rain cap 190 installed at the top of the tube body 170.
[0025] The T-shaped bracket 110 is made of aluminum alloy and is used to install other components. A dovetail groove is symmetrically opened on the top surface of the T-shaped bracket 110. At the same time, a dovetail protrusion is fixed on one side of the first sealing strip 120. The dovetail protrusion is embedded in the dovetail groove to facilitate the installation and removal of the first sealing strip 120. The first sealing strip 120 is used to adhere to the lower surface of the photovoltaic panel to enhance the sealing between the lower surface of the photovoltaic panel and the T-shaped bracket 110.
[0026] A groove 111 is formed at the top of the T-shaped bracket 110, and a plurality of through holes 112 are formed in an array at the bottom end of the T-shaped bracket 110 and are connected to the groove 111. The bottom end of the T-shaped plate 130 is embedded in the groove 111, which can limit the T-shaped plate 130 and ensure the stability of the T-shaped plate 130. The T-shaped plate 130 is also made of aluminum alloy material and is used to cooperate with the T-shaped bracket 110 to fix the end of the photovoltaic panel. A plurality of threaded holes 131 are formed in an array at the bottom end of the T-shaped plate 130. The bolts 150 pass through the through holes 112 and engage in the threaded holes 131 to fix the T-shaped bracket 110 and the T-shaped plate 130 together. At the same time, the first sealing strip 120 and the second sealing strip 140 are tightly fitted to the lower surface and the upper surface of the photovoltaic panel to prevent rainwater from passing through the gap between adjacent photovoltaic panels.
[0027] In addition, a dovetail groove is symmetrically provided at the bottom end of the T-shaped plate 130 , and a dovetail protrusion is also provided on one side of the second sealing strip 140 . The dovetail protrusion is embedded in the dovetail groove to facilitate installation and removal of the second sealing strip 140 .
[0028] The two sides of the T-shaped plate 130 are arranged in an inclined surface, and the outer side surfaces of the two sides of the shell 160 are perpendicular to the inclined surface of the T-shaped plate 130. A cavity 161 is opened inside the shell 160. The two sides of the shell 160 are arranged in an array with spray holes 162 connected to the cavity 161, so that the high-speed airflow in the cavity 161 can be sprayed out through the spray holes 162 and flow along the inclined surface of the T-shaped bracket 110, so as to blow away the rainwater on the photovoltaic panel close to the T-shaped bracket 110, and prevent the rainwater from penetrating to the side of the second sealing strip 140, thereby further improving the waterproof performance of the photovoltaic module.
[0029] The tube body 170 is connected to the cavity 161 and is used to install a high-speed fan 180. The high-speed fan 180 is used to suck in external air and accelerate it to blow it toward the cavity 161. A filter is installed on the inner wall of the tube body 170 to prevent dust and impurities from entering and clogging the spray hole 162. The rain cap 190 is conical to prevent rainwater from entering the tube body 170.
[0030] The working principle and use process of the utility model are as follows: when in use, the ends of adjacent photovoltaic panels are placed on the top of the T-shaped bracket 110, and then the bottom end of the T-shaped plate 130 is passed through between the adjacent photovoltaic panels and inserted into the groove 111 on the T-shaped bracket 110, and the bolt 150 is screwed into the threaded hole 131 on the T-shaped plate 130 through the through hole 112, and the bolt 150 is tightened, so that the first sealing strip 120 on the T-shaped bracket 110 and the second sealing strip 140 on the T-shaped plate 130 are tightly attached to the lower surface and the upper surface of the photovoltaic panel to prevent rainwater from passing through the gap between the adjacent photovoltaic panels. At the same time, in a rainy environment, the high-speed fan 180 is started to send a high-speed airflow into the cavity 161, and the high-speed airflow passes through the cavity 161 and enters the spray hole 162 to be sprayed out, which can blow away the rainwater on one side of the second sealing strip 140 to prevent rainwater from infiltrating to the second sealing strip 140.
[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
