Description

Technical Field

[0001] The utility model relates to the field of water conservancy engineering application research, in particular to a reservoir floating boat type pump station water intake device which takes high-quality water to supply water to the downstream to ensure water safety. Background Art

[0002] In water conservancy projects, for the purpose of comprehensive utilization such as irrigation and water supply, it is often necessary to draw water from artificial reservoirs and regulating ponds with large water level fluctuations.

[0003] The common practices at present are mainly as follows:

[0004] 1. Water intake with pressurized water inlet: During the construction of the reservoir, the amount of water required for irrigation, water supply, etc. is introduced within the specified water level change range, and the entry of silt and dirt is prevented as much as possible to improve the water quality, and then connected to the water transfer tunnel; this practice requires the establishment of high culvert, middle culvert and low culvert water intakes to meet the water intake needs of different water level intervals; after the reservoir has been in operation for many years within its service life cycle, due to siltation at the bottom of the reservoir, it is easy for the low culvert water intake to be blocked or silt to enter the water transfer tunnel from the low culvert, resulting in water quality deterioration; in recent years, the water intake buildings of this type of reservoir often need to be upgraded and renovated;

[0005] 2. Fixed pump station water intake: To build a fixed pump station water intake in a reservoir, it is necessary to first build a cofferdam, drain all the water in the cofferdam area, build a pump house, and then install water pumps, valves, pipelines, controls, etc. Its characteristics are: ① Long construction period, large cofferdam engineering, and high cost; ② High pump house cost, the greater the water level difference, the higher the pump house cost; ③ Because the water intake is fixed below the low water level, the water taken out is always the raw water from the bottom, with a high mud and sand content and poor water quality; ④ The water inlet pipe is always sunk to the bottom of the water. If it is blocked by dirt, it cannot be found and is difficult to clean; In recent years, this type of reservoir water intake building has been used less and less in the southwest region;

[0006] 3. Cable car type pump station water intake: A cable car type pump station is built on the slope of the reservoir to intake water. As the water level of the reservoir rises and falls, the cable car is pulled up and down along the track by a winch installed on the shore. Its characteristics are: ① Due to the great restrictions of terrain and geological conditions, the natural slope cannot be changed too much; ② Mud is easy to accumulate on the track; ③ When the inclination angle is small, the suction pipe is long and a tail car is required; ④ During operation, there are more water surface operations and there are safety hazards. In recent years, this type of reservoir water intake building has been used less and less in the southwest region. Summary of the invention

[0007] The utility model aims to solve the problems existing in the existing water intake methods in current water conservancy projects, and provides a reservoir floating boat type pump station water intake device which takes high-quality water and supplies water to the downstream to ensure water safety.

[0008] The water intake device of the floating ship type pumping station of the utility model is arranged on the water body outside the bank slope near the water intake of the reservoir. It is characterized in that the water intake device includes a floating ship pump house, an auxiliary cantilever, a steel anchor cable, an anchor pier, a water inlet steel pipe and a clean water tank. The anchor pier is arranged on the bank slope, the floating ship pump house is arranged on the water body, and the floating ship pump house and the anchor pier are connected and fixed by the auxiliary cantilever and the steel anchor cable; the clean water tank is arranged at the water inlet, and the floating ship pump house is connected with the clean water tank through the water inlet steel pipe; wherein:

[0009] The floating ship pump house includes a hull, a motor and a water pump. The water pump is arranged at the bottom of the hull and is connected with the water inlet steel pipe. The motor is installed in the hull to supply power to the water pump;

[0010] The anchor pier includes a main anchor pier and a deputy anchor pier. The main anchor pier is arranged on the bank slope corresponding to the floating ship pump house. There are two deputy anchor piers, which are symmetrically arranged on the bank slopes on the upstream and downstream sides of the main anchor pier. The main anchor pier is connected with the floating ship pump house through the auxiliary cantilever, and the deputy anchor pier is connected with the floating ship pump house through the steel anchor cable;

[0011] The clean water tank is arranged at the water intake. A check valve that opens unidirectionally is installed at the water intake. The rear end of the clean water tank is connected with a water conveyance tunnel, and there is a trash rack between the clean water tank and the water conveyance tunnel.

[0012] Both ends of the auxiliary cantilever are provided with universal joints, and are respectively connected with the main anchor pier and the floating ship pump house through the universal joints. When the water level in the reservoir rises or falls, it is convenient for the floating ship pump house to rise or fall accordingly and float on the water body to obtain high-quality surface water.

[0013] The water intake device of the floating ship type pumping station of the utility model has a simple structure, scientific design and convenient use. By floating the floating ship pump house on the water surface and pumping the surface water source in the reservoir through the water pump and injecting it into the clean water tank at the water intake, the renovation cost of the existing reservoir is greatly reduced. It can take high-quality water for downstream use, and has a low cost and is conducive to large-scale promotion. Brief Description of the Drawings
