Description

Technical Field

[0001] The utility model belongs to the technical field of water intake pump stations, and in particular relates to a submersible pump water intake pump station constructed in combination with a reservoir retaining wall or a revetment. Background Art

[0002] When building a new water intake pump station in an already filled reservoir, it is necessary to ensure that water can still be drawn normally when the water level of the reservoir is low. The use of existing fixed water intake pump stations usually faces the problem of underwater construction, which is difficult to construct, costly, and the construction period cannot be guaranteed. Utility Model Content

[0003] The utility model aims to provide a submersible pump water intake station built on a reservoir retaining wall or revetment in order to avoid underwater construction, which has the characteristics of small engineering volume, simple construction and stable operation.

[0004] A submersible pump water intake station is arranged on a retaining wall revetment that has been built on the shore of a reservoir area, and is characterized in that it includes a hoisting frame, a triangular support platform and a concrete support, wherein the concrete support is arranged on the top of the retaining wall revetment, and the side of the concrete support adjacent to the water does not exceed the counterweight type retaining wall revetment; the triangular support platform is fixed to the side of the concrete support adjacent to the water, and the triangular support platform is cantilevered to the water surface, a vertical downward flower sleeve is arranged on the triangular support platform, the diameter of the flower sleeve is larger than the widest part of the submersible pump, a water inlet hole is opened on the surface of the flower sleeve, a plurality of pipe clamps are arranged on the periphery of the flower sleeve, the pipe clamps are connected to anchor rods, and the anchor rods are fixed to the retaining wall revetment; a hoisting frame cantilevered out of the water is arranged on the concrete support, and a hoist is installed on the hoisting frame, and the hoist and the flower sleeve are located on the same vertical line; the submersible pump is arranged in the flower sleeve.

[0005] Furthermore, a guardrail is installed on the tripod support to protect the operators.

[0006] Furthermore, the flower sleeve is a steel pipe.

[0007] Furthermore, the surfaces of the hanging frame, the tripod bracket and the telephone sleeve are coated with an anti-corrosion coating.

[0008] The beneficial effects of the utility model are that the submersible pump of the water pump station is lifted and lowered by a hoist, ensuring that water can be normally drawn when the water level of the reservoir is low, and maintenance and repair can be carried out in time after the submersible pump fails, and the utility model has the advantages of small engineering workload, simple construction and stable operation.

[0012] Example 1: In the design of the water supply system of a hydropower station in the middle reaches of Jinsha River during operation, a submersible pump water intake station is adopted, which includes a counterweight retaining wall revetment 1, a hoisting frame 2, a triangular support platform 3 and a concrete support 4. The counterweight retaining wall revetment 1 is built on the shore of the reservoir area. A steel frame of the concrete support 4 is set on the top of the counterweight retaining wall revetment 1, and concrete is poured to form the concrete support 4. The top surface of the concrete support 4 is flush with the horizontal plane of the reservoir, and the side of the concrete support 4 adjacent to the water does not exceed the counterweight retaining wall revetment 1; the triangular support platform 3 is fixed on the side of the concrete support 4 adjacent to the water, and the triangular support platform 3 is cantilevered above the water surface. A guardrail 10 is installed on the triangular support platform 3 to protect the operators. A flower sleeve 5 is set downward on the triangular support platform 3. The diameter of the flower sleeve 5 is larger than the widest part of the submersible pump 6. A water inlet hole is opened on the surface of the flower sleeve 5. A number of pipe clamps 7 are set on the periphery of the flower sleeve 5. The pipe clamps 7 are connected to anchor rods 8, and the anchor rods 8 are fixed on the counterweight retaining wall revetment 4. A hoisting frame 2 is set on the concrete support 4, and a hoist 9 is installed on the hoisting frame 2. The hoist 9 and the flower sleeve 5 are located on the same vertical line; the submersible pump 6 is hoisted on the hoist 9 and hoisted in the flower sleeve 5.

[0013] The submersible pump 6 is lowered along the replacement casing 5 to the water level where water needs to be taken for water absorption by the hoist 9. When the submersible pump 6 fails or needs maintenance, the submersible pump 6 can also be lifted by the hoist 9 for inspection or replacement.
