Description

Technical Field

[0001] This application relates to the field of substation technology, and in particular to a semi-buried box-type substation. Background Technology

[0002] Substations are a crucial component of power systems, primarily functioning to transform voltage and distribute electrical energy. They include transformers, switchgear, and electrical conductors. With the ever-increasing demand for electricity and accelerated urbanization, the optimization and innovation of power supply facilities have become critical issues. Prefabricated substations, as an important part of the power distribution system, are widely used in various scenarios such as cities, rural areas, and industrial plants, shouldering the important responsibility of converting high-voltage electricity into low-voltage electricity and supplying it to users nearby. Simultaneously, prefabricated substations are also needed for power distribution and control at construction sites. Compared to traditional fully buried or above-ground substations, their installation and dismantling are less convenient after construction. Utility Model Content

[0003] The purpose of this application is to provide a semi-buried box-type substation to solve the technical problems of inconvenient installation and disassembly in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a semi-buried prefabricated substation is provided, including a substation body and a substation base; the substation body and the substation base are detachably connected; the substation base includes a U-shaped fixing box; an intermediate ring is provided on the outer circumference of the fixing box; the fixing box below the intermediate ring is buried underground; a cover plate is provided on top of the fixing box; a support plate is provided inside the fixing box; the support plate abuts against the lower surface of the cover plate.

[0005] With the above technical solution, during the installation process, an excavator first digs a pit in the ground that matches the size of the lower end of the substation base. Then, a crane places the substation base into the pit. Sand or stones are filled into the fixing box for counterweight, thus installing and fixing the base. Next, the substation main body is fixed to the substation base, with the cover plate serving as a support. During installation, the substation main body and substation base are not necessarily installed simultaneously; there may be a considerable time interval. The cover plate can shield the fixing box, preventing personnel from falling into it and reducing safety hazards. The cover plate is made of metal, and to prevent loss, it is connected to the fixing box for fixation and anti-theft. The support plate provides support for the cover plate.

[0006] Optionally, the fixing box includes a bottom plate at the bottom; the bottom plate is provided with a bottom hole; a cylinder is fixedly installed on the bottom plate; the upper end of the cylinder is connected to a support plate.

[0007] With the above technical solution, the fixed box can be hollow without a bottom plate. When a bottom plate is installed, it can be connected to the outside through the bottom hole to avoid water accumulation.

[0008] Optionally, the outer peripheral surface of the fixed box is provided with mounting holes; the main body of the substation includes a transformer box; several crossbeams are provided below the transformer box; mounting plates are connected to both ends of the crossbeams; the mounting plates are opposite to the outer peripheral surface of the fixed box; the mounting plates and the fixed box are fixed by screws passing through the mounting holes.

[0009] With the above technical solution, multiple mounting holes are provided, and the transformer box also has holes. A screw passes through both to connect the transformer box and the fixed box. The cover plate supports the transformer box and has ventilation holes. Several crossbeams and longitudinal beams are provided below the transformer box for connection. The crossbeams and longitudinal beams provide ventilation. At the same time, because the fixed box is positioned at a certain height relative to the ground, there is no need to worry about water flowing back into the transformer box.

[0010] Optionally, an installation box is provided on the outer peripheral surface of the fixing box; the installation box has strip-shaped vertical notches on both sides; the installation box also has arc-shaped notches on both sides; one end of the arc-shaped notch is located in the middle of the vertical notch, and the other end extends upward.

[0011] Optionally, the cover plate is connected to two connectors; the connectors mate with a vertical notch and an arc-shaped notch; the connectors include a connecting block; the connecting block is vertically connected to a middle block; the middle block is vertically connected to a first bending block; the first bending block is vertically connected to a second bending block; a first limiting post is provided on the connecting end where the first bending block and the second bending block are connected; a second limiting post is provided on the end of the second bending block away from the first bending block.

[0012] With the above technical solution, during the rotation of the cover plate relative to the fixed box, the first limiting post moves within the vertical notch and the second limiting post moves within the arc-shaped notch, thereby opening the cover plate to facilitate operation inside the fixed box by staff. The cover plate can also be closed to seal the fixed box, reduce safety hazards, and await subsequent operations. At the same time, the design of the connecting parts prevents the cover plate from being lost.

[0013] Optionally, the connecting block and the cover plate are fixedly connected by screws; the first limiting post is disposed in the vertical notch; the second limiting post cooperates with the arc-shaped notch for limiting.

[0014] Optionally, the cover plate is provided with a locking plate; the locking plate is provided with a strip-shaped through hole; a protruding plate is provided on the outer peripheral surface of the fixing box; the protruding plate is provided with a round hole, and after the cover plate closes to the fixing box, the protruding plate passes through the strip-shaped through hole.

[0015] With the above technical solution, the length of the strip-shaped through hole is greater than the width of the raised plate. Therefore, during the rotation of the cover plate, the raised plate is inserted into the strip-shaped through hole, and then the cover plate is locked by the cooperation of the lock and the round hole to prevent the cover plate from being lost. The cover plate can also be set to be connected to the fixed box below by a nut and screw structure. Compared with the structure of connecting parts and locks, it also has a certain anti-theft capability.

[0016] The beneficial effects of this application are: compared with the prior art, the semi-buried box-type substation provided by this application has the advantages of convenient installation and disassembly. Attached Figure Description
