Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-3, mining dust-protection type high tension switchgear, including the cabinet body 1, a plurality of inlet port 2 has been seted up to the side of the cabinet body 1, four draw-in grooves 3 that are the rectangular distribution in the outside of the cabinet body 1, the inside sliding connection of draw-in groove 3 has installation piece 4, fixedly connected with is close to the filtration frame 5 of inlet port 2 between four installation pieces 4, the inside of draw-in groove 3 is equipped with fixed establishment 6, specifically, fixed establishment 6 can make things convenient for quick fixes installation piece 4 inside draw-in groove 3, one side fixedly connected with of filtration frame 5 is the sealed 7 that fills up of U-shaped, the top of filtering frame 5 is equipped with clearance mechanism 8, specifically, in the use, can be convenient clear up filtering frame 5, prevent that every clearance from all needing to pull down filtering frame 5.

The scheme has the following working processes:

when the cabinet body 1 of high tension switchgear is used in pit inside, need start radiator fan and reduce the inside temperature of cubical switchboard, radiator fan needs inlet port 2 to get into the air, before starting radiator fan, need be close to four installation piece 4 respectively four draw-in grooves 3, then use fixed establishment 6 to fix four installation piece 4 inside draw-in grooves 3, at this moment sealed 7 and the contact of cabinet body 1, when starting radiator fan, can block the dust that gets into the inside air-carrying of inlet port 2 outside filtering frame 5, use clearance mechanism 8 to prevent the dust clearance to admit air and receive the influence after blockking the dust for a long time.

According to the working process, the following steps are known:

when the cabinet body 1 of high tension switchgear is used in the pit, the air filtration through the air inlet 2 is performed by using the filter frame 5, so that the dust is prevented from entering the cabinet body 1 and damaging the electric devices in the cabinet body 1, meanwhile, the filter frame 5 can be conveniently cleaned through the fixing mechanism 6, and the dust is prevented from entering the cabinet body 1 from a gap through the sealing gasket 7.

Further, fixed establishment 6 is including offering the fixed slot 601 in draw-in groove 3 one side, there is fixed plate 603 fixed slot 601's inside through extrusion spring 602 elastic connection, it is specific, when needs fixed mounting piece 4, extrude earlier fixed plate 603 and get into fixed slot 601, then put into draw-in groove 3 with installation piece 4, at last, relieve fixed plate 603, make fixed plate 603 pop out through extrusion spring 602, fixed plate 603 and installation piece 4 contact shelter from installation piece 4, prevent that installation piece 4 from leaving draw-in groove 3, when filter frame 5 is taken off to needs, can extrude fixed plate 603 and make fixed plate 603 get into fixed slot 601, then take out draw-in groove 3 with installation piece 4.

Further, the fixed plate 603 has seted up extrusion groove 604 near one side of installation piece 4, the inside of extrusion groove 604 has extrusion piece 606 through popping out spring 605 elastic connection, the cross-section of extrusion piece 606 is trapezoidal, anticreep groove 607 has been seted up to the one side of keeping away from fixed plate 603 of fixed slot 601, it is specific, when fixed plate 603 leaves fixed slot 601, extrusion piece 606 leaves extrusion groove 604 and installation piece 4 contact through popping out spring 605, the one end of fixed plate 603 gets into anticreep groove 607, installation piece 4 prevents through the extrusion piece 606 extrusion that filter frame 5 and cabinet body 1 from producing the gap.

Further, clearance mechanism 8 includes fixed connection in the locating piece 801 at filter frame 5 top, two stay cords 802 are worn to be equipped with at locating piece 801's top, fixedly connected with axis of rotation 803 between the one end of two stay cords 802, the surperficial cover of axis of rotation 803 is equipped with a burr section of thick bamboo 804, and is concrete, when needs are cleared up, can make axis of rotation 803 go up and down through pulling and relaxing stay cord 802 from top to bottom, thereby make burr section of thick bamboo 804 and filter frame 5 contact, the filtration hole that will filter frame 5 and be blockked up is beaten through, prevent that the too much influence of dust from admitting air.

Further, the inner side of the filter frame 5 is fixedly connected with two clamping rack bars 805, two gears 806 are sleeved on the surface of the burr cylinder 804, the gears 806 are meshed with the adjacent clamping rack bars 805, specifically, when the rotating shaft 803 descends or ascends, the burr cylinder 804 rotates through the meshing of the gears 806 and the clamping rack bars 805, and therefore burrs can be conveniently inserted into the filter holes to clean dust.

Further, fixedly connected with scraper blade 807 between the free end of two stay cords 802, two fixture blocks 808 of side fixedly connected with of the cabinet body 1, it is concrete, when need not clear up, put scraper blade 807 in two fixture blocks 808 below, prevent that scraper blade 807 from being pulled, when clearing up, scraper blade 807 will filter the dust on frame 5 surface and scrape down, prevent that filter frame 5 from being stopped up.

To sum up, can satisfy heat dissipation and dirt-proof function simultaneously when the cabinet body 1 is used in the pit, prevent that dustproof influence from reaching the required air current flow when heat dissipation to can clear up filter frame 5 when filter frame 5 fixes cabinet body 1, reduce the number of times of dismantling the clearance.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed.
