Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a high-efficiency and energy-saving water conservancy pump station. Background Art

[0002] Water conservancy projects refer to various types of projects (including new construction, expansion, reconstruction, reinforcement, repair, demolition and other projects) such as flood control, drainage, irrigation, hydropower generation, water diversion (supply), tidal flat management, soil and water conservation, and water resources protection, as well as their supporting and ancillary projects.

[0003] In water conservancy projects, drainage pump stations are important devices connecting inland rivers and external rivers. They are used to control the changes in water levels of inland rivers and external rivers, providing great convenience for alleviating droughts and floods. In the existing technology, there are a lot of debris and garbage in the water pools of most drainage pump stations. When the submersible pump pumps water, a lot of garbage and debris will block the water inlet of the submersible pump, causing the water outlet flow of the submersible pump to decrease, thereby reducing the drainage efficiency of the submersible pump and increasing energy loss. Therefore, it is necessary to redesign high-efficiency and energy-saving water conservancy pump stations to address the above problems. Utility Model Content

[0012] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0023] The outer wall of the leak hole cover 10 is fixedly connected to a moving frame 12 through a connecting mechanism. The connecting mechanism includes a plurality of connecting rods 11 fixedly installed on the outer wall of the leak hole cover 10, and the ends of each connecting rod 11 are fixedly connected to the outer wall of the moving frame 12. A reciprocating screw 13 is rotatably installed inside the moving frame 12. A second motor 14 connected to the reciprocating screw 13 is fixedly installed on the upper end surface of the moving frame 12. A screw sleeve 16 is threadedly installed on the outer wall of the reciprocating screw 13. A stabilizing rod 15 is fixedly installed inside the moving frame 12. The stabilizing rod 15 slides through the screw sleeve 16. The stabilizing rod 15 can limit the screw sleeve 16 so that the screw sleeve 16 can only move axially along the outer wall of the reciprocating screw 13. The outer wall of the screw sleeve 16 is fixedly connected to a cleaning brush 18 through a fixing mechanism. The fixing mechanism includes a fixing block 17 fixedly installed on the outer wall of the screw sleeve 16.

When the submersible pump 8 pumps water, the debris in the pool 1 can be intercepted and filtered by cooperating with the leakage hole cover 10 to avoid clogging the submersible pump 8, thereby preventing the discharge effect from being affected.

[0025] When debris adheres to the outer wall of the leakage hole cover 10 and causes blockage of the leakage hole, the second motor 14 drives the reciprocating screw 13 to rotate, and the reciprocating screw 13 drives the screw sleeve 16 to move through the cooperation of the stabilizing rod 15, and the screw sleeve 16 drives the cleaning brush 18 to move on the outer wall of the leakage hole cover 10 through the cooperation of the fixed block 17, so that the cleaning brush 18 can clean the debris on the outer wall of the leakage hole cover 10 and dredge the leakage hole, thereby ensuring the water circulation effect, avoiding reducing the water outlet flow of the submersible pump 8, and preventing its flow from being too small to increase energy loss, thereby achieving the purpose of high efficiency and energy saving.
