Problems solved by technology

[0002] The HGIS circuit breakers of the 500kV substation are arranged outdoors, and most of them use hydraulic spring mechanisms. It is designed according to the vertical installation direction. There is a rain curtain on the top and a drainage hole on the bottom. When the mechanism box is installed horizontally, the rain curtain and the drainage hole cannot play a good role in waterproofing and drainage. After a long time Water seepage and water accumulation in the mechanism box are prone to occur, causing defects such as corrosion of components in the mechanism box and reduced insulation performance

Embodiment 1

[0045] Such as Figure 1-Figure 6 As shown, the present invention provides an adjustable rainproof device, comprising two canopies 1, four support rods 2, a lifting mechanism 3 and an adjustment mechanism 4, the two canopies 1 are rotatably connected in a "human" shape, rain The shed 1 includes an inner canopy 11 and an outer canopy 12. The inner canopy 11 is placed in the outer canopy 12 and is slidably connected with the inner wall of the outer canopy 12. One end of the inner canopy 11 can extend out of the outer canopy 12, and the outer canopy The bottom of the shed 12 is parallel and spaced to be provided with two chute 121; in the present embodiment, as Figure 4As shown, the inner canopy 11 and the outer canopy 12 are made of transparent acrylic boards, wherein the outer canopy 12 is a box-type outer shed with a length of 1100mm, a width of 346mm and a thickness of 34mm, and is formed by bonding and encapsulating a transparent acrylic board with a thickness of 2mm. Thre...

Embodiment 2

[0057] This embodiment is further improved on the basis of Embodiment 1. A base is provided at the bottom of the screw lift 31, the diverter 32 and the driver 33. The base includes a circular stainless steel base plate with a diameter of 100 mm and a thickness of 20 mm, and is welded vertically to the base plate. A steel pipe pillar with a height of 305mm, an outer diameter of 40mm, and a thickness of 2mm. Four holes with a diameter of 21mm are opened around the bottom plate. M12 anchor bolts are installed on the holes. There are seven bases in total, all of which are on the same level. Add a screw lift 31. The reliability of the connection between the diverter 32 and the driver 33 and the ground.

Abstract

The invention belongs to the technical field of electrical equipment waterproofing, and discloses an adjustable rainproof device which comprises two rain sheds, four supporting rods, a lifting mechanism and an adjusting mechanism, wherein the rain sheds comprise the inner rain shed and the outer rain shed, the inner rain shed is arranged in the outer rain shed and is in sliding connection with the inner wall of the outer rain shed, and two sliding grooves are formed in the bottom of the outer rain shed in parallel at intervals; the supporting rods are in one-to-one correspondence with the sliding grooves, rollers are arranged at one ends of the supporting rods, and the rollers are in rolling connection with the sliding grooves; the lifting mechanism is installed at the other ends of the supporting rods and can drive the four supporting rods to ascend or descend in the vertical direction at the same time. The adjusting mechanism comprises a handheld rod, a first adjusting rod and a second adjusting rod, a first threaded hole and a second threaded hole which are opposite in rotating direction are formed in the two ends of the handheld rod, the first adjusting rod is in threaded connection with the first threaded hole, and the second adjusting rod is in threaded connection with the second threaded hole. According to the adjustable rainproof device, the lifting height and the opening and closing angle of the two rain sheds can be controlled, and ideal rain shielding operation conditions are obtained.

Description

technical field [0001] The invention relates to the technical field of waterproofing of power equipment, in particular to an adjustable rainproof device. Background technique [0002] The HGIS circuit breakers of the 500kV substation are arranged outdoors, and most of them use hydraulic spring mechanisms. It is designed according to the vertical installation direction. There is a rain curtain on the top and a drainage hole on the bottom. When the mechanism box is installed horizontally, the rain curtain and the drainage hole cannot play a good role in waterproofing and drainage. After a long time Water seepage and water accumulation in the mechanism box are prone to occur, causing defects such as corrosion of components in the mechanism box and reduced insulation performance. Contents of the invention [0003] The object of the present invention is to provide an adjustable rain-proof device, which can control the rain-shielding area, lifting height and opening and closing...
