Description

Mining flame-proof type control box

Technical Field

The utility model relates to a control box, a mining flame-proof type control box specifically says so.

Background

The electrical control box used in the underground places needs higher explosion-proof requirements for the use of the built-in electricity because the external environment is in the state of containing dust and explosive gas. The transparent window is usually arranged on the box body or the box cover of the existing electric control box for visually seeing the internal display, the explosion-proof performance of the window structure directly provided with the transparent glass is difficult to guarantee, and the explosion-proof structure in the box and the transparent window becomes a problem to be solved urgently in the existing electric control box.

Disclosure of Invention

The utility model provides a simple structure can effectively solve the explosion-proof mining flame-proof type control box in visual window position.

The utility model adopts the technical proposal that: the utility model provides a mining flame-proof type control box, includes box, case lid, and case lid one side articulates through the hinge and is the case lid and corresponds box upper end flange lid dress state on the box, its characterized in that: the box cover is provided with a view port, the inner end face of the box cover of the view port is sequentially pressed and connected with a sealing gasket, a transparent piece and a copper gasket through a pressing plate, the inner wall of the box body, the inner end face of the box cover and the pressing plate are coated with arc-resistant paint, the side wall of the box body is connected with more than one outgoing line connecting shaft, and the outer port of the outgoing line connecting shaft is screwed and compressed through a rubber ring, a gasket and a blocking piece by a compression nut.

The case lid is connected with the nameplate through a rivet, and the thickness of the bottom of the rivet hole of the case lid is larger than 3mm.

And 204-1 antirust oil is coated on the flange edge cover mounting surface.

The transparent piece is an acrylic plate with the plate thickness larger than the box cover thickness.

And a plurality of positioning frames for locking the electric parts by screws are arranged on the inner side wall and/or the bottom surface of the box body, and arc-resistant paint is coated on the positioning frames.

And a handle is arranged on the side edge of the box body.

The box cover is locked with the flange edge at the upper end of the box body through the inner hexagon screw.

And the lower part of the side edge of the box body is connected with a grounding post.

Technical scheme more than adopting, the utility model discloses the beneficial effect who reaches is:

1. the inner wall of the box body adopts a positioning frame structure, and each electronic element can be locked and fixed by a locking screw through a threaded fixing hole on the positioning frame, so that the internal electronic elements are prevented from shaking, electric arcs are generated by mutual elements, the generation of the electric arcs is effectively reduced, and the safety performance is improved;

2. the box body, the positioning frame and the box cover form a packaging cavity, and the box body, the positioning frame and the box cover are coated with arc-resistant paint, so that arc extinguishing is effectively realized, and the explosion-proof safety performance is improved conveniently;

3. when the wiring is assembled, the compression nut is screwed down, the plugging sheet is taken down, the compression nut is screwed up again for compression, the threading penetrates out through the compression nut, and the sealing performance is good;

4. the visual port part adopts an acrylic plate, the inner side of the visual port part adopts a sealing pad to be packaged by a pressing plate, the pressing plate is coated with arc-resistant paint to extinguish arc and prevent explosion, and the outer side of the visual port part improves the compression sealing performance by a copper gasket.
