Description

A distribution box for water conservancy projects

technical field

The utility model relates to the field of electrical equipment, in particular to a power distribution box for water conservancy projects.

Background technique

Water conservancy projects are collectively referred to as flood control, flood control, irrigation, power generation, water supply, reclamation, soil and water conservation, resettlement, water resources protection and other projects (including new construction, expansion, reconstruction, reinforcement, and restoration) and their supporting and ancillary projects. It is also called water conservancy project, which is constructed for the purpose of disposing of natural surface water and groundwater to achieve the purpose of eliminating harm and benefiting. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources.

Most of the traditional distribution boxes used in water conservancy projects are built on a support frame of a certain height, but if the height of the support frame is high, although its anti-flooding ability is good, it is inconvenient for the maintenance of the distribution box. It is difficult to guarantee its flood resistance.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-4, the present utility model provides a technical solution: a power distribution box for water conservancy projects, including:

The base 1 has two parallel side plates 11 vertically arranged on it, and the side plates 11 are vertically arranged with corresponding chutes 12:

The box body 2 is covered with a protective cover 21. The left and right side walls of the protective cover 21 are provided with a plurality of groups of rollers 22 that are inserted into the chute 12. The rollers 22 can move along the chute. 12 Rolling up and down, the top of the protective cover 21 is provided with a No. 1 steel rope 23 for hoisting it, and the No. 1 steel rope 23 bypasses the No. 1 fixed pulley group 24 fixed on the side plate 11;

The floating plate 3 is arranged below the box body 2 and floats on the liquid surface, and the floating plate 3 is provided with a through groove for the side plate 11 to pass through;
