Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering, in particular to a multi-layer horizontal centrifugal pump station structure. Background Art

[0002] Pump stations are hydraulic structures commonly used in water conservancy projects. Traditional pump stations adopt a single-story layout. Generally, water pumps are arranged horizontally in a single-story underground plant, and control and work rooms are set up on the ground. This layout is more suitable in open areas and places with relatively abundant land. At present, the level of urbanization in my country is getting higher and higher, and cities across the country need to build a large number of pump stations for flood control. However, for some areas with limited land, the traditional layout of pump stations is difficult to meet the needs of engineering and land use. Utility Model Content

[0003] The purpose of the utility model is to propose a multi-layer horizontal centrifugal pump station structure that can be used when the site is extremely narrow, or the inlet and outlet channels are very narrow and difficult to widen, or the water inlet is a pipe and the pipe is inconvenient to branch, so as to solve the problem of tight land use and adapt to the new needs of pump station development.

[0004] A multi-story horizontal centrifugal pump station structure, characterized in that it includes a station body arranged below the ground, the station body is divided into a water tank and a main plant by a vertical partition wall, the main plant is further divided from top to bottom into an electrical auxiliary plant, a cable mezzanine and a two-story pump room by a horizontal partition wall, the top of the water tank is flush with the top of the cable mezzanine; a gate is opened at the upper part of the other side of the water tank away from the main plant, and a gate controlled by a hoist is arranged on the gate, and the hoist is fixed to the top of the station body; a number of water pumps are arranged in each pump room, each water pump is connected to a water inlet pipe and a water outlet pipe, the water inlet pipe mouth extends into the water tank, the water outlet pipe is buried in the partition wall and connected from the upper part of the station body to the outside of the station body.

[0005] Furthermore, a bridge-type lifting device is arranged on the top of the pump room and runs through the pump room from left to right, for lifting during installation and maintenance of the water pump.

[0006] Furthermore, the main factory building is provided with a hanging hole which runs through the main factory building from top to bottom and is used as a transportation channel.

[0007] Furthermore, an inverted siphon inlet is arranged outside the gate.

[0008] Furthermore, the main factory building is provided with a building water collection well, a maintenance water collection well and stairs that are connected from top to bottom on the left and right sides.

[0009] The beneficial effects of the utility model are as follows: the invention has a simple layout, is easy to install, has a low cost of use, and a high degree of integration. It solves the problem that traditional pump stations are difficult to build in extremely small sites, or when the inlet and outlet channels are very narrow and difficult to widen, or when the water inlet is a pipe and the pipe is inconvenient to branch. It makes full use of limited land resources and greatly improves the utilization rate of urban land. Secondly, when the water demand is small, the sluice gate is partially opened, the water storage tank is filled with water, and some or all of the water pumps in the lower pump room are used for pumping; when the water demand is large, the sluice gate is fully opened, and some or all of the water pumps in the upper and lower pump rooms in the main plant are turned on to work, so that the water pumps can be reasonably called according to demand to improve efficiency. Finally, the excavation area of ​​the foundation pit is small and the enclosure range is reduced, so it is particularly suitable for pump and sluice hub sites and sites with limited width of inlet and outlet water diversion channels.
