Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a photovoltaic circuit breaker controller with carrier function, comprising a controller 1, a connection hole 2 is provided on one side surface of the controller 1, a display light 3 is provided on the upper surface of the controller 1, a heat dissipation mechanism 4 is provided inside the controller 1, and a fixing mechanism 5 is provided on the lower surface of the controller 1;

[0021] The fixing mechanism 5 includes a bottom plate 501, a fixing column 502, a connecting shell 503, a block 504, a first spring 505, a second spring 506 and a latch 507. The bottom plate 501 is fixedly installed on the lower surface of the controller 1, the fixing column 502 is fixedly connected to the upper surface of the bottom plate 501, the connecting shell 503 is fixedly connected to the upper surface of the fixing column 502, the outer surface of the connecting shell 503 is fixedly connected to the block 504, one side of the block 504 is fixedly connected to the first spring 505, the inside of the connecting shell 503 is fixedly connected to the second spring 506, one end of the second spring 506 is fixedly connected to the latch 507, and the controller 1 is fixedly connected to the bottom surface of the controller 1. Through the arrangement of the bottom plate 501, the fixing column 502, the connecting shell 503, the card block 504, the first spring 505, the second spring 506 and the card bolt 507, when in use, the controller 1 is first passed through the holes on both sides of the fixing column 502. When the controller 1 is pressed downward, the shells on both sides will compress the card block 504 to cause deformation. The card block 504 will compress the first spring 505 so that the fixing column 502 can pass through the holes on the shells on both sides of the controller 1. After passing through, the first spring 505 rebounds, so that the card block 504 unfolds and fixes the controller 1, so that the controller 1 is fixed on the bottom plate 501, so that the controller 1 can be fixedly operated and is convenient to use.

[0022] Furthermore, the heat dissipation mechanism 4 includes a heat dissipation plate 401, heat dissipation holes 402, a protective shell 403, a fan 404 and a dustproof net 405. The heat dissipation plate 401 is fixedly connected to one side of the controller 1, and the heat dissipation holes 402 are opened on the surface of one side of the heat dissipation plate 401. The inside of the controller 1 is fixedly connected to the protective shell 403, and the inside of the protective shell 403 is provided with a fan 404. A dustproof net 405 is fixedly installed on one side of the protective shell 403. Through the arrangement of the heat dissipation plate 401, the heat dissipation holes 402, the protective shell 403, the fan 404 and the dustproof net 405, when in use, the electrical fan 404 is started, and the fan 404 will blow hot air out from the heat dissipation holes 402 to cool down the controller 1, thereby preventing malfunctions caused by overheating. The dustproof net 405 can prevent some tiny insects and other dust particles from entering the fan 404, thereby preventing the heat dissipation efficiency from being affected.

[0023] Furthermore, the fixing columns 502 are symmetrically arranged with respect to the central axis of the base plate 501 , and two groups of fixing columns 502 are arranged. By arranging the fixing columns 502 , the controller 1 can be fixed on the base plate 501 , so as to better fix the operation.

[0024] Furthermore, the second spring 506 is fixed above the fixing column 502 , and the clamping block 504 is made of plastic. Through the arrangement of the clamping block 504 , the structure of the controller 1 is more stable when it is fixed on the base plate 501 .

[0025] Furthermore, the latch 507 and the second spring 506 form a telescopic structure, and the latch block 504 is provided with four groups. Through the provision of the latch 507, the operation is more convenient when the controller 1 is fixed on the base plate 501.

[0027] Furthermore, the protective shell 403 is arranged inside the controller 1, and the fan 404 is symmetrically arranged with respect to the central axis of the heat sink 401. By setting the protective shell 403, the motor of the fan 404 can be protected and the service life of the heat sink can be extended.

[0028] Working principle: First, pass the controller 1 through the holes on both sides of the fixing column 502. When the controller 1 is pressed downward, the shells on both sides will compress the block 504 to cause deformation. The block 504 will compress the first spring 505 so that the fixing column 502 can pass through the holes on the shells on both sides of the controller 1. After passing through, the first spring 505 rebounds, causing the block 504 to expand and fix the controller 1, thereby fixing the controller 1 on the bottom plate 501, so that the controller 1 can be fixedly operated and convenient to use. Secondly, when in use, start the electrical fan 404, and the fan 404 will blow hot air out from the heat dissipation hole 402 to cool down the controller 1, thereby preventing malfunctions caused by overheating. The dustproof net 405 can prevent some tiny insects and other dust particles from entering the fan 404, thereby preventing the heat dissipation efficiency from being affected.
