Lower box body structure of half-buried box-type substation

Abstract

The invention provides a lower box body structure of a half-buried box-type substation. The lower part of the lower box body structure is a transformer room, a neck port for being connected with an upper box body upwardly extends from one side of the top of the lower box body structure, and the rest part of the lower box body structure is an upper surface; the upper surface is provided with an upper surface opening, the size of the upper surface opening is enough for the access of a transformer, and an upper surface cover plate is arranged on the upper surface opening; the upper surface cover plate is provided with an operating hole which is used for the access of people, and an operating door is arranged on the operating hole; a lower box body is arranged under the ground surface, the upper part of the neck of the lower box body is higher than the ground surface, and the lower part of the lower box body is lower than the ground surface; an outer frame is arranged at the periphery of the operating door, the outer frame comprises an upper frame and a lower frame, and a lifting adjustment device for adjusting the relative distance from the upper frame to the lower frame is arranged in the outer frame; the upper frame is provided with a ground surface cover plate, and the ground surface cover plate is level with the ground surface; and an empty well is formed between the ground surface cover plate and the upper surface cover plate. According to the lower box body structure of the half-buried box-type substation, the ground surface cover plate is ensured to be level with the ground plane, and thus, the safety of pedestrians and vehicles and the overall appearance are ensured; and meanwhile, a safeguard measure is provided for operating personnel accessing the operating hole.

Description

technical field [0001] The invention relates to the technical field of a semi-buried box-type substation, in particular to a lower box structure of a semi-buried box-type substation. Background technique [0002] At present, semi-buried box-type substations have been promoted and used one after another, especially in the reconstruction of old cities, the construction of new districts, and the design of roads in prosperous commercial areas. This semi-buried box-type substation usually has an upper box as a switch cabinet room and a lower box as a transformer room. The upper box part is generally set on the ground, the outer facade is designed as a light box advertisement, and the lower box is buried below the ground. Since the section of the upper box is smaller than that of the lower box, it has the advantage of reducing the occupied area. But the existing semi-buried box-type substation still has the following defects: (1) in one case, there is an upper surface opening on...

AI Technical Summary

Problems solved by technology

However, the existing semi-buried box-type substation still has the following defects: (1) In one case, there is an upper surface opening on the upper surface of the lower box body, and the size can meet the entrance and exit of the transformer.

Although this method can control the cover plate to be flush with the ground surface, there is a problem of poor waterproof sealing
