Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a high-voltage distribution cabinet convenient for installation. Background Technique

[0002] A high-voltage distribution cabinet refers to an electrical product that plays roles such as on-off, control, or protection in the processes of power generation, transmission, distribution, power conversion, and consumption in a power system, with a voltage level ranging from 3.6 kV to 550 kV. It mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switch cabinets. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry. Its specific structure is a heat dissipation and dust-proof high-voltage distribution cabinet convenient for installation proposed in the patent publication number CN219203861U, including a high-voltage distribution cabinet body placed outdoors for storing electrical appliances in the power system, a chassis support mechanism connected to the bottom end of the high-voltage distribution cabinet body. The chassis support mechanism includes a movable wheel connected to one end of the bottom of the high-voltage distribution cabinet body, a chassis support for receiving the movable wheel, and a hollow groove opened on the lower end surface of the chassis support, as well as a warning mechanism placed at the central position on all four sides of the high-voltage distribution cabinet body for warning in all directions.

[0003] Through the above settings, the high-voltage distribution cabinet of the prior art adds a chassis support mechanism at the bottom end of the high-voltage distribution cabinet. The chassis support is a detachable device. When installing the high-voltage distribution cabinet, the movable wheel on the chassis support can drive the high-voltage distribution cabinet to move and change its position. At the same time, a warning device is added, so that the high-voltage distribution cabinet automatically turns on in the night environment to remind pedestrians not to touch it, reducing electric shock accidents.

[0004] However, the high-voltage distribution cabinet of the prior art solution has the following defects during operation:

[0005] (1) When the staff places the high-voltage distribution cabinet on the chassis support mechanism, it is necessary to insert the movable wheel shaft body into the movable wheel and the hollow round hole and penetrate the distribution cabinet. Because it is not easy to align the movable wheel and the hollow round hole, it is very troublesome to find the hole, resulting in a significant increase in working time. Content of the Utility Model

[0006] The utility model aims to provide a high-voltage distribution cabinet convenient for installation, mainly used to solve the technical problem that when the high-voltage distribution cabinet is placed on the chassis support mechanism in the prior art, it is necessary to insert the movable wheel shaft body into the movable wheel and the hollow round hole and penetrate the distribution cabinet. Because it is not easy to align the movable wheel and the hollow round hole, it is very troublesome to find the hole.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A high-voltage distribution cabinet that is easy to install includes a high-voltage distribution cabinet body and a chassis bracket. Fixed blocks are fixedly connected to the relative positions of the inner two side walls of the chassis bracket. A hollow groove is penetrated through the upper end surface of the fixed block. An angle iron is fixedly connected to the lower outer wall of the high-voltage distribution cabinet, and the angle iron coincides with the hollow groove. Semicircular holes are symmetrically opened at the bottom of the high-voltage distribution cabinet body. Grooves are opened at both ends of the inner wall of the chassis bracket. A slide groove is opened on the inner wall of the groove. Two movable wheels are rollingly connected in the slide groove. A rotating shaft matching the semicircular hole is rotatably connected between the relative movable wheels, and one end of the rotating shaft extends into the groove. A push groove is opened on the upper end surface of the chassis bracket, and the push groove is connected to the groove. A fixing component for fixing the movement of the rotating shaft is arranged in the push groove.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When it is necessary to install a high-voltage distribution cabinet, the staff will first place the chassis bracket on the ground, then measure the distance between the semicircular holes at the bottom of the high-voltage distribution cabinet, and then move the rotating shaft. The rotating shaft drives the movable wheel to roll, and the distance between the two rotating shafts is moved to be consistent with the distance of the semicircular holes. The rotating shaft is then fixed by the fixing component. After the high-voltage distribution cabinet is placed, the fixing component is released to move the position of the high-voltage distribution cabinet. After determining the position, the position of the high-voltage distribution cabinet is fixed by the angle iron.

[0011] 2. Beneficial effects:

One end of the metal rod sequentially penetrates the receiving hole and the extension hole. A corrugated cover is fixedly connected between the opposite strip-shaped blocks, and a circular hole is penetrated and opened on the upper end surface of the corrugated cover. The threaded rod penetrates the circular hole and is threadedly connected with the threaded hole. By fixedly connecting the L-shaped blocks, four in number, to the upper end surface of the chassis bracket, placing the strip-shaped block inside the L-shaped blocks, fixedly connecting the corrugated cover between the opposite strip-shaped blocks, and threading the threaded rod through the circular hole penetrated and opened on the upper end surface of the corrugated cover and threadedly connecting it with the threaded hole opened on the outer wall of the rotating shaft, the push groove is protected to prevent garbage such as fallen leaves and dust from falling into it.
