Embodiment 1
[0026] see Figure 1-6 , a protective device for a power distribution cabinet with a heat dissipation function, comprising a protective box 1 and a box door 2 with damping and rotatingly installed on the protective box 1, the side wall of the protective box 1 is provided with several In the ventilation hole 3 for heat dissipation, a dynamic heat dissipation component is provided on the side wall of the protective box 1, and a U-shaped limit seat 4 is fixedly installed on the side wall of the protective box 1. The dynamic heat dissipation component includes a cooling fan 5. A heat dissipation motor 6 for driving the heat dissipation fan 5 to rotate, a swing assembly and a lifting assembly for driving the heat dissipation fan 5 to move, and the heat dissipation motor 6 is arranged on the swing assembly;
[0027] The swing assembly includes an L-shaped fixing seat 7 fixedly installed on the side wall of the protective box 1 and a support rod 8 for fixing the heat dissipation moto...
Embodiment 2
[0036] This embodiment is further improved on the basis of the embodiment. The improvement is that: a blind slot 42 is opened on the side wall of the protective box 1 located on the side of the ventilation hole 3, and a filter assembly is arranged in the blind slot 42. The filter assembly includes a snap-in seat 43 slidably installed in the blind slot 42 and a filter screen 44 cooperating with the snap-in seat 43, the snap-in seat 43 is connected to the bottom wall of the blind slot 42 for pop-up filtering The elastic support member 45 of the net 44, the open end of the blind groove 42 can be detachably installed with a limit pressure block 46; by setting the filter screen 44, under the action of the elastic support member 45, dust-proof filtration can be realized while filtering Easy removal of the net 44.
[0037] The elastic supporting member 45 is not limited. In this embodiment, preferably, the elastic supporting member 45 is a compression spring.
[0038] The working pr...
