Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1
As shown in fig. 1, the utility model discloses a sealed explosion-proof electrical cabinet, which comprises a cabinet body 1 and a pressure relief device 2 arranged at the top end of the cabinet body 1. Specifically, as shown in fig. 2, the pressure relief device 2 includes a pressure relief opening 3 formed at the top of the cabinet 1, a pressure relief cylinder 13 disposed at the top of the cabinet 1, and an upper cover 9 movably fastened to the upper end of the pressure relief cylinder 13. The pressure relief opening 3 is located inside the pressure relief cylinder 13, i.e. the pressure relief cylinder 13 encloses the pressure relief opening 3 therein.
The upper cover 9 is provided with a cover wall extending downwards, a pressure relief channel 11 is formed between the cover wall and the outer side wall of the pressure relief cylinder 13, the side wall of the pressure relief cylinder 13 is provided with a pressure relief hole 7, and the lower end of the cover wall of the upper cover 9 is lower than the pressure relief hole 7, so that the inside of the pressure relief cylinder 13 is communicated with the pressure relief channel 11 through the pressure relief hole 7.
In this embodiment, the end of the pressure relief hole 7 away from the center of the pressure relief cylinder 13 is inclined downward, so that rainwater cannot enter the pressure relief cylinder 13 through the pressure relief hole 7, and the rainproof performance of the electrical cabinet is improved.
In this embodiment, the acute angle formed between the pressure relief hole 7 and the horizontal plane is 15 degrees, so that the rainwater cannot go to the pressure relief cylinder 13, and the exhaust of the pressure relief hole 7 cannot be influenced.
When the pressure relief valve is used, gas in the electrical cabinet enters the pressure relief cylinder 13 from the pressure relief port 3 and is exhausted from the pressure relief hole 7. If the air pressure in the cabinet body rises sharply, the air pressure can open the upper cover 9, so that the exhaust efficiency is improved.
Example 2
On the basis of embodiment 1, the pressure relief device 2 further includes two upper cover limiting mechanisms oppositely disposed at the upper end of the pressure relief cylinder 13, and an upper cover plate 8 connected to the upper ends of the two upper cover limiting mechanisms.
Specifically, the upper cover limiting mechanism comprises an upper cover limiting rod 10, the lower end of which is fixed at the upper end of a pressure relief cylinder 13, the upper end of which penetrates through an upper cover 9 and is fixedly connected with an upper cover plate 8, and a compression spring 4 which is sleeved on the upper cover limiting rod 10 and is positioned between the upper cover plate 8 and the upper cover 9. The upper cover 9 can move up and down along the upper cover limiting rod 10.
Because the upper cover limiting rod 10 and the upper cover 9 are in clearance fit, rainwater may flow downwards along the upper cover limiting rod 0 and enter the pressure relief cylinder 13, in order to prevent this, as shown in fig. 3, a concave table 12 is arranged at the upper end of the pressure relief cylinder 13, the concave table 12 is communicated with the pressure relief channel 11, and the upper cover limiting rod 10 is fixed on the concave table 12. Therefore, if rainwater flows down along the upper cover limiting rod 10, the rainwater flows to one side of the pressure relief channel 11, and the rainwater is prevented from entering the pressure relief cylinder 13.
When the air pressure rises sharply, the upper cover 9 is pressed to be pushed upwards and opened, the air pressure can be discharged out of the cabinet body 1, and after the air pressure falls back, the upper cover 9 is covered on the pressure relief cylinder 13 again under the action of the compression spring 4 and the self gravity.
Example 3
The embodiment is basically the same as the embodiment 1 or 2, and the difference is that the pressure relief device 2 in the embodiment further comprises a sealing plate 6 covering the pressure relief opening 3, and a sealing plate limiting rod 5 with the upper end fixed on an upper cover 9; the lower extreme of closing plate gag lever post 5 passes closing plate 6, closing plate 6 can reciprocate along closing plate gag lever post 5, and can open pressure release mouth 3 when closing plate 6 rebound.
When the air pressure in the cabinet body 1 rises to a certain degree, the air pressure pushes the pressure relief opening 3 open, the air enters the pressure relief barrel 13 and is discharged out of the cabinet body 1, and the pressure relief opening 3 is covered by the sealing plate 6 after the air pressure falls back. Through setting up sealing plate 6, can reduce the probability that outside mosquito enters into cabinet 1 inside, play the effect of protection inside device.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are included in the scope of the claims of the present invention, as long as they do not depart from the idea of the present invention, and they should be regarded as what the present invention protects.
As described above, the present invention can be preferably realized.
