[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-7 A heat dissipation housing for an inverter of a photovoltaic device includes a housing body 1, two heat dissipation fans 2 are provided on both sides of the interior of the housing body 1, dust filters 3 for ventilation and dust prevention are provided on both sides of the housing body 1, the heat dissipation fans 2 and the dust filters 3 are positioned correspondingly, and an air outlet 4 is provided on the upper surface of the housing body 1.

[0028] It can be understood that air is blown into the shell body 1 through the heat dissipation fan 2, and the heat in the shell body 1 is dissipated through the air outlet 4 to achieve the purpose of heat dissipation. Under the action of the dust filter 3, the dust entering the shell body 1 is filtered.

[0029] Specifically, cleaning components 5 for cleaning the dust filter 3 are symmetrically arranged on both sides of the shell body 1. The cleaning components 5 include a cleaning brush 502 for cleaning the dust filter 3 and a dust hood 501 for dust collection. The cleaning brush 502 is fixedly connected to the inside of the dust hood 501, and the cleaning brush 502 overlaps the surface of the dust filter 3. The cleaning component 5 also includes two slides 503 and two sliders 504 for lifting the dust hood 501. The two slides 503 are fixedly connected to the side of the shell body 1, and the two sliders 504 are respectively slidably connected to the inner walls of the two slides 503. The dust hood 501 is fixedly connected to the surfaces of the two sliders 504. The cleaning brush 502 and the dust hood 501 are both slidably connected to the side of the shell body 1 through the sliders 504 and the slide rails.

[0030] It can be understood that by providing a cleaning brush 502, the cleaning brush 502 slides up and down on the surface of the slide groove 503 through the slider 504, and the dust on the surface of the dust filter 3 is cleaned in time to prevent dust accumulation from affecting the ventilation effect.

[0031] Specifically, a dust collection component 6 for generating negative pressure in the dust collection hood 501 is provided on the lower surface of the shell body 1. The dust collection component 6 includes an exhaust fan 601 and an air duct 602 for connecting the exhaust fan 601 with the dust collection hood 501. The air duct 602 includes a connecting shell and two hoses. Both hoses are connected to the connecting shell. The other ends of the two hoses are respectively connected to the two dust collection hoods 501. The connecting shell is fixedly connected to the lower surface of the shell body 1, and the exhaust fan 601 is fixedly connected to the surface of the connecting shell.

[0032] It can be understood that since the cleaning brush 502 can easily bring dust into the outer shell body 1 when cleaning the dust filter cover, the cooling fan 2 can be stopped when cleaning the dust filter cover. At the same time, the dust cover 501 can generate negative pressure through the exhaust fan 601 to promptly remove dust from the surface of the dust filter net 3 to prevent dust from entering the outer shell body 1.

[0033] Specifically, a lifting assembly 7 is fixedly connected to the lower surface of the shell body 1. The lifting assembly 7 includes a protective shell 701 and two groups of threaded columns 702 symmetrically arranged inside the protective shell 701. The protective shell 701 is U-shaped. The protective shell 701 is fixedly connected to the lower surface of the shell body 1. The threaded column 702 is rotatably connected to the inner wall of the protective shell 701 through a bearing. The surface of the threaded column 702 is threadedly connected to a moving block 703. The moving block 703 is slidably connected to the bottom wall of the protective shell 701. The upper surface of the moving block 703 and the surface of the dust cover 501 are both hinged with a connecting rod 704. The two groups of threaded columns 702 are connected through a transmission mechanism 705. The transmission structure includes two synchronous wheels and a synchronous belt. The two synchronous wheels are respectively arranged on the surfaces of the two threaded columns 702. The two synchronous wheels are connected through a synchronous belt transmission. A driving motor is provided at one end of one of the threaded columns 702.

[0034] It can be understood that the threaded column 702 is driven to rotate by the driving motor, and with the cooperation of the synchronous belt and the synchronous wheel, the two threaded columns 702 synchronously drive the moving block 703 to move, thereby adjusting the support angle of the connecting rod 704, so that the connecting rod 704 drives the dust collector 501 to move up and down through the slider 504.

[0035] Specifically, a temperature sensor 8 is provided inside the housing body 1 .

[0036] It is understandable that by real-time monitoring of the temperature inside the housing body 1 by the temperature sensor 8 , the power of the cooling fan 2 can be adjusted in real time to achieve the best cooling effect and increase the service life of the cooling fan 2 .

[0037] Specifically, a shielding plate 9 is fixedly connected to the upper surface of the housing body 1 .

[0038] It is understandable that by providing the shielding plate 9, rainwater is prevented from entering the housing body 1 through the air outlet 4, and at the same time, direct sunlight can be prevented from shining on the housing body 1, causing the housing body 1 to be overheated.

[0039] The utility model is characterized in that air is blown into the shell body 1 by the heat dissipation fan 2 and the heat in the shell body 1 is dissipated through the air outlet 4 to achieve the purpose of heat dissipation. The dust entering the shell body 1 is filtered by the dust filter 3. When the heat dissipation fan 2 works for a period of time, the heat dissipation fan 2 stops working, and the driving motor drives the threaded column 702 to rotate. Under the action of the synchronous belt and the synchronous wheel, the two threaded columns 702 rotate synchronously, and the threaded column 702 drives the moving block 703 and the lower end of the connecting rod 704 to move. The support angle of the connecting rod 704 is adjusted to push the dust hood 501 and the cleaning brush 502 to slide through the slide groove 503 of the slider 504, so that the cleaning brush 502 cleans the dust on the surface of the dust filter 3. At the same time, the exhaust fan 601 is started, and the dust hood 501 generates negative pressure under the action of the air duct 602, so that the cleaned dust is promptly extracted. After the cleaning is completed, the cleaning brush 502 and the dust hood 501 are reset, so that the heat dissipation fan 2 continues to perform heat dissipation.
