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.

[0026] like Figure 1-Figure 8 As shown, a low-voltage switch cabinet comprises a cabinet body 1, wherein an air inlet 10 and an air outlet 11 are respectively provided on two symmetrical sides of the cabinet body 1, a dustproof component for shielding the air inlet 10 is provided on one side of the cabinet body 1, and a heat dissipation component connected to the air outlet 11 is provided on the other side of the cabinet body 1; a cabinet door for convenient opening and closing is provided on the front side of the cabinet body 1;

[0027] A fixed plate 4 is also installed on one side of the top of the cabinet 1, and a cleaning structure 5 for cleaning the dust-proof components is arranged on the fixed plate 4. The cleaning structure 5 includes a lift plate 52 that can be raised and lowered, and a cleaning brush plate 53 is arranged on one side of the lift plate 52. The lift plate 52 is connected to a power part for driving the lifting thereof, and one side of the cleaning brush plate 53 is beveled to form a cleaning brush portion that contacts the dust-proof components.

[0028] Specifically, Figure 5 and Figure 6 As shown, the power part includes a protection box 51 and an electric push rod 56 installed on the top of the fixed plate 4. The telescopic end of the electric push rod 56 is connected to the top of the lifting plate 52, and the protection box 51 is covered on the outside of the electric push rod 56.

[0029] Specifically, Figure 1-Figure 4 As shown, the heat dissipation component includes a heat dissipation box 2 installed on one side of the cabinet 1, a heat dissipation fan 9 is installed in the heat dissipation box 2, and an exhaust port is opened on one side of the heat dissipation box 2, a baffle 3 is installed in the exhaust port, and the air outlet 11 connects the heat dissipation box 2 with the cabinet 1.

[0030] Specifically, Figure 2 and Figure 3 As shown, the dustproof component includes a fixing frame 6 fixed on the side wall of the cabinet 1 , and a dustproof net 7 is arranged inside the fixing frame 6 .

[0031] When the low-voltage switch cabinet is used, the cabinet door is first opened, and then the electrical components are installed into the cabinet body 1, and the cabinet door is closed, and then the low-voltage switch cabinet is connected to the circuit to realize the operation of the low-voltage switch cabinet. During the operation of the low-voltage switch cabinet, the cooling fan 9 can be operated to suck the external air into the cabinet body 1 through the air inlet 10, and the air in the cabinet body 1 is sucked out through the air outlet 11 and discharged through the exhaust port, so as to realize the efficient heat dissipation of the low-voltage switch cabinet and ensure the normal operation of the low-voltage switch cabinet;

[0032] At the same time, during the heat dissipation process of the low-voltage switch cabinet, the dustproof net 7 in the fixing frame 6 can filter the air to prevent dust from entering the cabinet body 1 to ensure the normal operation of the low-voltage switch cabinet;

[0033] When the dust screen 7 needs to be cleaned, the electric push rod 56 can be used to drive the lifting plate 52 to descend along the fixed frame 6. At this time, the lifting plate 52 drives the cleaning plate 53 to descend synchronously, so that the cleaning plate 53 can clean the dust screen 7 through its cleaning part, thereby cleaning the dust screen 7 and avoiding clogging of the dust screen 7 and affecting the air intake, which is beneficial to ensure ventilation and heat dissipation of the low-voltage switch cabinet.

[0034] Furthermore, if Figure 3 As shown, a mounting groove for mounting the dustproof net 7 is provided on the fixing frame 6, and a cover plate 8 for sealing the mounting groove is installed at one end of the dustproof net 7.

[0035] When the dustproof net 7 is installed, the dustproof net 7 can be inserted into the installation groove on the fixed frame 6 through the cover plate 8 until the cover plate 8 seals the installation groove to complete the installation of the dustproof net 7, and when the dustproof net 7 is removed, the dustproof net 7 can be pulled out of the installation groove through the cover plate 8 to realize the removal of the dustproof net 7, thereby realizing the quick disassembly and assembly of the dustproof net 7 and facilitating the replacement of the dustproof net 7.

[0036] In addition, in one embodiment, if Figure 3 , Figure 5-Figure 8 As shown, the dust cleaning structure 5 also includes a connecting structure for fixing the lifting plate 52 and the cleaning brush plate 53. The connecting structure includes two connecting blocks 54 installed on one side of the cleaning brush plate 53, and two connecting grooves 55 opened on the lifting plate 52. The lifting plate 52 is also provided with an elastic clamping component 57 for plugging and fixing the connecting block 54.

[0037] Specifically, Figure 6 and Figure 8 As shown, the elastic clamping component 57 includes a cavity opened in the lifting plate 52, and a spring 571 installed in the cavity, the cavity is connected to the connecting groove 55, one end of the spring 571 is connected to the moving plate 573, and one end of the moving plate 573 is fixed with an insertion rod 572, a through hole is opened inside the connecting block 54 for the insertion rod 572 to pass through, a pull rod 574 is installed at the top of the moving plate 573, and a slot is opened on the top of the lifting plate 52 for the pull rod 574 to move, and the slot is connected to the cavity.

[0038] When the cleaning plate 53 needs to be replaced, the movable plate 573 can be pulled by the pull rod 574, so that the movable plate 573 squeezes and contracts the spring 571, and at the same time, the movable plate 573 drives the plug 572 to be pulled out of the connecting block 54, and then the cleaning plate 53 is pulled upward to move the connecting block 54 out of the connecting groove 55 to separate the cleaning plate 53 and the lifting plate 52, and then the cleaning plate 53 is replaced. After the replacement, the movable plate 573 can be pulled by the pull rod 574 to move the movable plate 573. The plate 573 squeezes and contracts the spring 571 to retract the insertion rod 572 into the cavity, and then installs the cleaning plate 53 on the lifting plate 52 through the connecting block 54 and the connecting groove 55, and releases the pull rod 574. At this time, the movable plate 573 pushes the insertion rod 572 under the action of the spring 571 to plug and fix the connecting block 54 to achieve the installation of the cleaning plate 53, thereby achieving rapid disassembly and assembly of the cleaning plate 53, facilitating the replacement of the cleaning plate 53, and ensuring the cleaning effect of the cleaning plate 53 on the dustproof net 7.
