Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage vacuum power distribution for mines, in particular to a high-voltage permanent magnet mechanism vacuum power distribution device for mines. Background Art

[0002] If sparks or electric arcs are generated in an environment with explosive dangers of mixed gas and coal dust in coal mines, it may cause an explosion and cause serious safety accidents. The common distribution device is easy to generate electric sparks or arcs when working, so the distribution device used in the mine needs to have a flameproof function and isolate the electric sparks or arcs inside the distribution device to prevent them from igniting external flammable gases and causing explosions.

[0003] In the existing mining high-voltage permanent magnet mechanism vacuum distribution device, the cabinet body and the cabinet door are usually fixed directly with multiple bolts during use. During inspection and maintenance, it is usually necessary to remove multiple bolts, and then tighten the bolts one by one after the maintenance is completed. The cabinet door with this structure makes the operation of opening and closing the door time-consuming and laborious, seriously affecting the work efficiency. In addition, although the existing mining high-voltage permanent magnet mechanism vacuum distribution device has a cabinet door hinged, in actual use, the hinges are often worn after opening and closing, which causes a gap between the cabinet door close to the hinge direction and the cabinet body, resulting in poor airtightness of the cabinet door. Therefore, a mining high-voltage permanent magnet mechanism vacuum distribution device is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 1

[0029] The utility model provides a technical solution: a vacuum power distribution device of a high-voltage permanent magnet mechanism for mining, comprising a vacuum power distribution cabinet and a cabinet door, wherein a supporting leg is arranged on the lower surface of the vacuum power distribution cabinet, the cabinet door is arranged in front of the vacuum power distribution cabinet, a limiting block is arranged on the outer surface of the vacuum power distribution cabinet, an adjusting block is slidably connected to the inner wall of the limiting block, a first hinge is arranged on the outer surface of the adjusting block, an adjusting bolt is inserted into the inner wall of the adjusting block, one end of the adjusting bolt is threadedly connected to the inner wall of the limiting block, two adjusting bolts are arranged symmetrically, a second hinge is arranged on the outer surface of the cabinet door, and one end of the second hinge is rotatably connected to the inner wall of the first hinge through a shaft rod.

[0030] In order to facilitate the compensation of hinge wear, as shown in the attached Figures 1 to 3 As shown, the present application adopts the following structure. By setting the limit block, the adjustment block and the adjustment bolt, the vacuum distribution device of the high-voltage permanent magnet mechanism for mining has the effect of facilitating the compensation of the wear of the hinge. When the cabinet door is opened and closed many times, the hinge with the vacuum distribution cabinet body often wears out, causing the rotation center of the cabinet door to shift toward the front of the vacuum distribution cabinet body. At this time, the clamping force between the vacuum distribution cabinet body and the cabinet door near the hinge is often smaller than the other side. At this time, the adjustment bolt can be tightened to drive the adjustment block to move toward the inside of the limit block, thereby driving the first hinge and the second hinge to move toward the rear of the vacuum distribution cabinet body, thereby compensating for the offset of the position of the rotation center, enabling the cabinet door to fit the cabinet body tightly again, improving the sealing of the cabinet door and the vacuum distribution cabinet body, thereby achieving the purpose of facilitating the compensation of the wear of the hinge.

[0031] Example 2

[0032] The utility model provides a technical solution: the outer surface of the vacuum distribution cabinet is provided with a third hinge, the inner side wall of the third hinge is rotatably connected with a pull rod, one end of the pull rod is provided with a fourth hinge, the inner side wall of the fourth hinge is rotatably connected with a cam, the lower side of the outer surface of the cam is provided with a labor-saving rod, the lower end of the labor-saving rod is provided with a connecting frame, the outer surface of the connecting frame is provided with a sliding groove, the outer surface of the movable block is provided with a first rotating shaft, the outer surface of the first rotating shaft is slidably connected with the inner side wall of the sliding groove, the inner side wall of the connecting frame is movably connected with the movable block, and the movable block A threaded column is inserted into the inner wall of the threaded seat, one end of the threaded column is threadedly connected to the inner wall of the threaded seat, a connecting block is provided at one end of the threaded column, and a notch is opened on the outer surface of the connecting block. There are four notches and they are evenly distributed in a circular array. A hand-tightening knob is provided in front of the connecting block. The inner wall of the vacuum distribution cabinet is rotatably connected to the threaded seat through the second rotating shaft. A gasket is provided on the rear side of the cam in front of the cabinet door, and the outer surface of the cam abuts against the front of the gasket. A sleeve is provided on the outer surface of the supporting leg, and a power assist rod is inserted into the inside of the sleeve.

[0033] In order to save effort and make the connection between the cabinet door and the cabinet body tighter, as shown in the attached Figures 4 to 6 As shown, the present application adopts the following structure. Through the arrangement of the fourth hinge, cam and threaded column, the mine-used high-voltage permanent magnet mechanism vacuum distribution device has the effect of facilitating the tight closing of the cabinet door. When in use, in the open state, the pull rod is rotated to the right. When closing the cabinet door, the pull rod is rotated to the front, and then the labor-saving rod is rotated downward to make the protrusion of the cam fit the front of the gasket. When the labor-saving rod approaches the vertical state, according to the principle of lever, the pressing force of the protrusion of the cam on the gasket is increased, so that the cabinet door fits the front of the vacuum distribution cabinet more closely, and at this time, one end of the threaded column can be screwed into the interior of the threaded seat. The arrangement of the connecting frame, the slide groove, the first rotating shaft and the movable block can effectively increase With the flexibility of the threaded column, the threaded column can be manually tightened by turning the knob by hand, and finally the booster rod can be removed from the sleeve and inserted into the slot to tighten the threaded column. Furthermore, through the principle of leverage, it can not only save the force when closing the cabinet door, but also make the cabinet door and the vacuum distribution cabinet fit more tightly. Through the coordinated setting of the fourth hinge and the cam, during use, the cabinet door can be closed tightly with more effort. Compared with the traditional bolt connection method, it saves installation and disassembly steps, and compared with the connection method of nuts and bolts in the hinged method, it is more labor-saving and can make the cabinet door and the cabinet fit more tightly, thereby achieving the purpose of saving effort while making the connection between the cabinet door and the cabinet body tighter.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
