The cabinet door is connected to the front of the cabinet. The middle part is protruding, and its lower end is provided with a set of water guide grooves that fit with the inner wall of the rainproof plate. At the middle height, the water guide groove at the lowest point is connected with a water guide pipe, which is fixed on the inner wall of the cabinet and extends to the bottom of the cabinet to communicate with the outside. Symmetrical shutters and the first filter layer are arranged on both sides of the cabinet. , The second filter layer, the area of the louvers is at least half of the area of the side panel of the cabinet where it is located, one of the two opposite louvers is equipped with an outward-facing negative pressure fan, and the negative pressure fan is connected to a temperature control switch, and the temperature control switch is arranged on the inner wall of the cabinet.

In the above technical solution, in the above technical solution, the mesh density of the second filter layer is greater than the mesh density of the first filter layer.

In the above technical solution, the first filter layer and the second filter layer are connected to the side plate of the cabinet body by clipping, and the inside of the side plate is stepped.

In the above technical solution, the number of said negative pressure fans is at least two.

The beneficial effects of the utility model are: by setting the rainproof plate and the water guide groove, the rainwater can be blocked, and at the same time, the condensed water condensed on the inner wall of the rainproof plate slides into the water guide groove and is exported outside the cabinet through the water guide pipe, preventing the condensed water from dripping into the On the electrical equipment in the power cabinet; there are shutters and two layers of filters on both sides of the cabinet, which can prevent dust from entering the cabinet while dissipating heat; when the temperature inside the cabinet is too high, the temperature control switch is connected to the negative pressure fan The power supply, through the form of negative pressure fan active suction, accelerates the air flow in the cabinet, and further dissipates heat to the electrical equipment in the cabinet.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

A dust-proof power cabinet as shown in Fig. 1, Fig. 2 and Fig. 3 includes a cabinet body 1, a set of distribution boards, a cabinet door 2, a negative pressure fan 3, and a temperature control switch 4. The top of the cabinet body 1 A group of reserved holes are respectively provided at the bottom and the bottom of the cabinet. A group of distribution boards are fixed and installed on the bottom of the cabinet 1 through special screws for the distribution cabinet. The cabinet door 2 is connected to the front of the cabinet 1, and the top of the cabinet 1 is connected with an anti- The rain plate 5, the middle part of the rain plate 5 protrudes, and its lower end is provided with a group of water guide grooves 6 that fit with the inner wall of the rain plate 5. The joint between the water guide groove 6 and the rain plate 5 is high, Its diagonal is low, and the other two diagonal water guides 6 are at the middle height, and the lowest water guide 6 is connected with a water guide 7, and the water guide 7 is fixed on the inner wall of the cabinet body 1 and extends to the bottom of the cabinet body 1. The outside is connected, and both sides of the cabinet 1 are provided with symmetrical shutters 8, a first filter layer 9, and a second filter layer 10. The area of the shutters 8 is at least the area of the side plate of the cabinet 1 where it is located. On the other hand, one of the two opposite shutters 8 is provided with an outward-facing negative pressure fan 3 , and the negative pressure fan 3 is connected with a temperature control switch 4 , and the temperature control switch 4 is arranged on the inner wall of the cabinet body 1 .

In the above technical solution, the mesh density of the second filter layer 10 is greater than the mesh density of the first filter layer 9 . The first filter layer 9 is used for coarse filtration to filter out large particles of dust, and the second filter layer 10 is used for fine filtration to filter out fine dust. After two times of filtration, the dust is basically filtered out, and the dustproof effect is better.
