GIS dust cover with adjustable width and height and telescopic ceiling

Abstract

The invention provides a GIS dust cover with adjustable width and height and a telescopic ceiling. The GIS dust cover with the adjustable width and height and the telescopic ceiling comprises a wall and the ceiling. The GIS dust over is characterized in that the wall comprises an outer frame, an inner frame which can ascend and descend is arranged in the outer frame in a sleeved mode, the ceiling is fixed to the inner frame, a hoof supporting fame which can be spread towards the two sides is arranged at the bottom of the outer frame, and supporting hooves extending downwards are arranged in the middle of the hoof supporting frame. The GIS dust cover can be conveniently suitable for construction and application on places having different heights and unequal-altitude terrain through the double frames and a hand-rocking lifting mechanism, and assembly and disassembly are convenient; in addition, by the adoption of the supporting hooves of the outer frame, the stability of a ceiling body is further improved; besides, the ceiling body is installed through mutual connection of a pair of triangular trusses and a fixing support, and the ceiling of the GIS dust cover can be opened or closed according to lifting needs through a movable frame with an inclined top surface capable of sliding.

Description

technical field [0001] The invention relates to a GIS dustproof cover with adjustable width and height and telescopic ceiling function. Background technique [0002] The existing GIS installation shed ceiling device is usually composed of a frame, rain cloth (rain shield), connecting device, etc. When installing the ceiling, it is necessary to combine multiple small parts before installation, which is troublesome to install and disassemble, and takes a long time , It is not conducive to the construction needs of fast installation. At present, the specifications and sizes of GIS on the market are slightly different, such as height and width. At the same time, the space of the GIS installation site is limited. Especially during installation, it is necessary to set up a temporary hoisting structure for hoisting. susceptible to damage. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that ...
