High-strength hinge structure for box door of box-type substation

Abstract

A high-strength hinge structure for a box-type transformer substation door comprises a plurality of hinges, hinge sleeves, hinges and hinge blocks, the hinges are used for fixing a door plate of the transformer substation door and a box-type transformer substation stand column, each hinge comprises a first connecting part and a second connecting part which are perpendicularly connected with each other, one end of each first connecting part is connected with the corresponding hinge block after being bent, and the other end of each first connecting part is connected with the corresponding hinge block after being bent. The second connecting part is connected with a box transformer substation stand column, a groove is formed in the second connecting part, and the hinge sleeve is connected with the first connecting part of the hinge and installed on the box transformer substation stand column through the hinge block. One end of the hinge and the hinge sleeve are matched with the hinge block to be installed on the box transformer substation stand column, the other end of the hinge enables the edge end face of the door plate and the edge end face of the box transformer substation stand column to be located on the same horizontal plane through the design of the groove, and therefore the problem that strength is insufficient due to the fact that connection is achieved only through a small-size hinge is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of fixed box-type substations for power transmission, and in particular to a high-strength hinge structure for a box door of a box-type substation. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed and movable steel structure box. The outer door panel of this box is large in size, the conventional hinge size is small, and the connection surface is small. When used in places with strong winds such as airports and coastal areas, the door panel is easily blown away or torn and deformed by the wind due to insufficient connection strength. Utility Model Content

[0004] The technical solution adopted by the utility model is:

[0005] A high-strength hinge structure for a box-type substation door, comprising a plurality of hinges, hinge sleeves, hinges and hinge blocks. The hinges are used to fix the door panels of the substation door and the box-type transformer column. The hinge comprises a first connection part and a second connection part which are vertically connected to each other. One end of the first connection part is bent and connected to the hinge block. The second connection part is connected to the box-type transformer column. A groove is provided on the second connection part. The hinge sleeve is connected to the first connection part of the hinge and is installed on the box-type transformer column through the hinge block.

[0006] Further optimized, the bent portion of the first connecting portion is arranged parallel to the second connecting portion.

[0007] Further optimization, the bent part of the first connecting part is fixedly connected to the hinge sleeve, a rotating shaft is provided in the hinge sleeve, the upper and lower ends of the rotating shaft are connected to hinge blocks, the hinge sleeve rotates around the rotating shaft to drive the hinge and the door panel to rotate.

[0008] Further optimized, multiple hinges are arranged from top to bottom.

[0009] In further optimization, the groove is bent inwardly of the hinge and extends in a direction away from the first connecting portion, and the extended portion is used to fix the door panel.

[0010] For further optimization, the hinge sleeve is made of 45# steel pipe with galvanized surface.

[0011] Further optimization, the hinge is made of cold-rolled steel plate with a thickness of 4.0 mm and a galvanized surface.

[0012] Further optimization, the hinge block is made of cold-rolled steel plate with a thickness of 20 mm and a galvanized surface.

[0013] The beneficial effects of the utility model are:

[0014] One end of the hinge and the hinge sleeve are installed on the box-type transformer column in conjunction with the hinge block. The other end of the hinge is designed with a bevel so that the edge end surface of the door panel and the edge end surface of the box-type transformer column are on the same horizontal plane, thereby improving the problem of insufficient strength caused by only relying on small-size hinge connections.
