Dedusting and cooling integrated device of solar photovoltaic panel

[0020] The present invention will be described in detail below with reference to the accompanying drawings.

[0021] refer to figure 1 , 2 As shown, the present invention provides an integrated dedusting and cooling device for a solar photovoltaic panel, including a dedusting system, a cooling pipeline system, a pool 5, and a solar photovoltaic panel 10 installed on the pool 5 through a bracket, wherein the dedusting system includes The spray pipe 11 is installed on the top of the solar photovoltaic panel 10. The spray pipe is connected to the Y-shaped hose 3 and the pool 5 through a water pump, and absorbs the water stored in the pool 5. The pool 5 is cemented and the top is provided with a sealing cover. , and a square pool buried in the ground. A brush 4 for cleaning the solar photovoltaic panel 10 is installed on the front of the solar photovoltaic panel 10, and the bottom end of the solar photovoltaic panel 10 is connected with the pool 5 through a pipeline to form a loop; for details, see image 3 As shown, the two parallel edges of the front of the solar photovoltaic panel 10 are respectively installed with a lead screw 9 and a guide rod 12, and the two ends of the rotating brush 4 are slidably connected to the lead screw 9 and the guide rod 12. The main motor 7 is connected to the lead screw 9, the main motor 7 drives the lead screw 9 to rotate, and the lead screw 9 drives the brush 4 to reciprocate up and down. Further, in order to enable the water in the pool 5 to be better recycled, the bottom end of the solar photovoltaic panel 10 in the present invention is provided with a filter device for filtering the cleaning water. After filtering and purifying the washed water, it is returned to the Pool 5, forming a loop.

[0022] The cooling pipeline system includes a cooling plate 1 engraved with cooling channels, the cooling plate 1 is arranged on the back of the solar photovoltaic panel 10, the outlet and the inlet of the cooling plate 1 are connected with the horizontal spiral pipe 2 to form a sealed loop, and Cooling liquid is arranged in the sealed circuit, the horizontal spiral tube 2 is placed in the pool 5, the outer diameter of the horizontal spiral tube 2 is 10 mm, the inner diameter is 8 mm, and the spiral diameter is 150 mm. Among them, the structure of the cooling plate 1 mainly has two forms: the first is that the cooling plate 1 is a plexiglass heat-receiving slot plate, and the plexiglass heat-receiving slot plate is etched with multiple rows of longitudinal serpentine grooves, and the plexiglass heat-receiving slot plate The inside of the slot plate is sealed with glass glue, and the surrounding is sealed with hot melt glue. The second form is: a longitudinal row of serpentine pipes is installed on the cooling plate 1 .

[0023] Further, refer to Figure 4 As shown, since the solar photovoltaic panels in the solar farm are arranged in an array, in order to facilitate the water filling of the pool 5 , connecting pipes 6 that communicate with each other are installed on the side wall of the pool 5 .

[0024] The working principle of the present invention is:

[0025] Dust removal system: inject water into the pool 5, when the solar photovoltaic panels need to be cleaned, turn on the water pump, and the water pump will pump the water in the pool 5 into the spray pipe 11, and the water will flow out through the small holes on the spray pipe to wash On the surface of the solar photovoltaic panel, the motor and the main motor are also turned on, so that the brush 4 moves up and down while rotating, further cleaning the solar photovoltaic panel, and achieving the purpose of removing the dust on the surface of the solar photovoltaic panel 10 .

[0026] Cooling pipeline system: Since a cooling plate 1 engraved with a cooling channel is installed on the back of the solar photovoltaic panel 10, and the cooling channel is filled with cooling liquid, the condensate first absorbs the heat of the solar photovoltaic panel 10, so that the temperature of the condensate increases , the condensate flows out from the outlet of the cooling plate 1, and flows into the horizontal spiral tube 2 through the pipeline, and the horizontal spiral tube 2 is placed in the pool 5. Therefore, the condensate exchanges heat with the low-temperature water in the pool 5, releasing the heat. Afterwards, it becomes a low-temperature condensate, and returns to the inlet of the cooling panel 1 through a pipeline to form a sealed loop, and the water pool finally dissipates the heat to the ground to achieve the purpose of cooling the solar photovoltaic panel 10 .

[0027] The invention adopts the back circulating water of the solar photovoltaic panel to obtain heat, the water flows through the horizontal spiral tube to dissipate heat to the pool, and the water in the pool transfers the heat to the earth. When the solar radiation is too strong, the water in the pool will not dissipate the heat in time. It is temporarily stored, and then scattered to the ground at night to achieve cooling of the solar photovoltaic panels; at the same time, the water in the pool acts as a circulating washing water, which works together with the longitudinal rotating brush to achieve dust removal on the surface of the solar photovoltaic panels. Compared with the traditional artificial dust removal and natural air-cooled solar photovoltaic panels, the advantages of this device are: greatly save labor costs and washing water, can perform dust removal operations in time, and can effectively improve the power generation efficiency of solar photovoltaic panels. Compared with the separate dust removal device and cooling device, the advantages of this device are: the integration of dust removal and cooling is realized, the comprehensive energy consumption of the device is low, and the equipment investment to achieve the same production capacity is low.
