Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic inverter which is convenient for heat dissipation. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels, controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form a large-area solar cell module, which is then combined with power controllers and other components to form a photovoltaic power generation device.

[0003] A Chinese patent publication number CN212231342U discloses a box-type photovoltaic inverter that is convenient for exhaust and heat dissipation. The inverter comprises a box body, an aluminum plate, thermally conductive silicone and a first filter. Through the performance of the aluminum plate and the thermally conductive silicone inside the box body and the box cover, and the operation of a fan, the outside wind is conveniently passed through the first filter into the inside of the box body and then flows to the outside, thereby facilitating exhaust and heat dissipation of the inverter components inside the box body.

[0004] However, when the device is dissipating heat through the fan, the outside wind must first pass through the first filter before entering the interior of the box. Since the surface of the first filter is prone to accumulate a lot of dust and other tiny particles, these impurities will gradually clog the holes in the filter, and the air flow rate will be significantly affected, resulting in a reduction in the amount of air entering the box through the first filter, thereby reducing the direct cooling effect of the fan on the photovoltaic inverter.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention drives the rotating shaft and the fixed rod to rotate through a dual-axis motor, and the fixed rod drives the T-shaped plate and the brush to rotate through the T-shaped slot 1, and the T-shaped plate drives the fixed bar and the semicircular plate to rotate. When the semicircular plate rotates to the inside of the arc cover, the outer wall of the semicircular plate abuts and slides with the plurality of arc plates. Under the joint action of the elastic member 1, the T-shaped plate drives the brush to rotate and reciprocates up and down at the same time, so that the brush can more thoroughly remove dust from the surface of the second filter plate, and dust and impurities are not easy to block the holes on the second filter plate, and the air flow speed is not easy to reduce, so as to ensure the air volume entering the shell through the second filter plate, thereby improving the direct cooling effect of the fan blade on the photovoltaic inverter;

[0023] By turning on the dual-axis motor to drive the shaft and the fan blades to rotate, the fan blades rotate and the outside air is blown into the shell through the second filter plate to dissipate heat from the inverter body.

[0024] When the bristles are driven to move up and down reciprocatingly by the T-shaped plate, the T-shaped plate drives the fixed plate and the second fixed column to move reciprocatingly, and the second fixed column drives the strip plate to rotate through the through slot. When the strip plate rotates, the first fixed column and the T-shaped strip are driven to move reciprocatingly through the through slot on the other side, and the T-shaped strip drives multiple scraping rods to move reciprocatingly. At the same time, the scraping rods move in opposite directions to the bristles, so that the scraping rods push the bristles to make the dust on the bristles fall off, ensuring that the dust on the bristles is not easy to block the second filter plate for a second time, and improving the quality of the bristles to remove dust on the surface of the second filter plate, further increasing the air volume entering the shell, and improving the heat dissipation efficiency;

[0025] Through the blowing of the fan blades, part of the air enters the connecting pipe from the hood, and is sprayed from the nozzle to the top surface of the shell through the connecting pipe. At the same time, the fixed rod rotates to drive the push plate to rotate. When the push plate rotates and contacts the rotating rod, it pushes the rotating rod and the connecting pipe to rotate and squeezes the elastic member 2. After the rotating rod rotates a certain angle and moves away from the push plate, the push plate separates from the rotating rod. Under the elastic force of the elastic member 2, the rotating rod rotates and drives the connecting pipe and the nozzle to rotate, so that the nozzle swings back and forth in an arc. The gas discharged from the nozzle completely removes the dust on the top surface of the shell, thereby improving the heat dissipation efficiency of the shell and the inverter body.

[0067] The specific solution is as follows: the dual-axis motor 205 is turned on to drive the rotating shaft 206 and the fan blades 207 to rotate. When the fan blades 207 rotate, the outside air is blown into the shell 1 through the filter plate 203 to dissipate heat for the inverter body 102, and the heat on the surface of the inverter body 102 is blown out of the shell 1 through the filter plate 1 104, so as to dissipate heat and cool the inverter body 102, ensuring that the inverter body 102 is not easy to overheat. At the same time, the rotating shaft 206 and the fixed rod 301 rotate, and the fixed rod 301 drives the T-shaped plate 303 and the bristles 304 to rotate through the T-shaped slot 1 302, and the T-shaped plate 303 drives the fixing bar 305 and the semicircular plate 306 to rotate.

When the T-shaped plate 303 drives the bristles 304 to move up and down reciprocatingly, the T-shaped plate 303 drives the fixed plate 405 and the fixed column 2 406 to move back and forth, and the fixed column 2 406 passes through the through groove 4 08 drives the strip plate 407 to rotate. When the strip plate 407 rotates, the fixed column 1 404 and the T-shaped strip 402 are driven to reciprocate through the through slot 408 on the other side. The T-shaped strip 402 drives multiple scraping rods 403 to reciprocate. At the same time, the scraping rods 403 move in opposite directions to the bristles 304, so that the scraping rods 403 push the bristles 304 to make the dust on the bristles 304 fall off, ensuring that the dust on the bristles 304 is not easy to block the filter plate 203 for a second time, and improving the quality of the bristles 304 to remove dust on the surface of the filter plate 203, further increasing the air volume entering the shell 1, improving the heat dissipation efficiency, and the fan blades 207 blow air, and part of the air enters the connecting pipe 501 from the air hood 502. The liquid is sprayed from the nozzle 503 to the top surface of the shell 1 through the connecting pipe 501. At the same time, the fixed rod 301 rotates and drives the push plate 505 to rotate. When the push plate 505 rotates and contacts the rotating rod 504, the rotating rod 504 and the connecting pipe 501 are pushed to rotate and squeeze the elastic member 508. After the rotating rod 504 rotates a certain angle and moves away from the push plate 505, the push plate 505 is separated from the rotating rod 504. Under the elastic force of the elastic member 508, the rotating rod 504 rotates and drives the connecting pipe 501 and the nozzle 503 to rotate, so that the nozzle 503 swings back and forth in an arc. The gas discharged from the nozzle 503 completely removes the dust on the top surface of the shell 1, thereby improving the heat dissipation efficiency of the shell 1 and the inverter body 102.
