Water level pumping and lowering device for hydraulic engineering construction

Abstract

The invention relates to the technical field of water conservancy engineering, in particular to a water level pumping and lowering device for water conservancy engineering construction, which includes an output shaft through which the guide ring is driven to rotate, and the guide ring rotates the arc-shaped groove and the V-shaped groove. When the inside of the arc-shaped groove moves relatively, the distance between the arc-shaped groove and the center line of the output shaft is constant, so the round block does not rotate. When the round block moves to the inside of the V-shaped groove, the distance between each position in the V-shaped groove The distance between the centerlines is not constant, so when the round block moves relatively in the V-shaped groove, the connecting rod plate and the second gear swing back and forth along the first horizontal axis, and the second gear swings back and forth to drive the third gear, the first gear, The ring-shaped inner rack and the ring-shaped filter screen swing back and forth, and the number of teeth of the second gear is greater than that of the third gear, thereby increasing the swing range of the ring-shaped filter screen relative to the connecting rod plate, scraping impurities on the surface of the ring-shaped filter screen in a wider range, The anti-clogging function is realized, and the smoothness of water inlet is improved.

Description

technical field [0001] The invention relates to a water level pumping and lowering device for water conservancy engineering construction, which belongs to the technical field of water conservancy engineering. Background technique [0002] Construction drainage of water conservancy projects refers to the discharge of water that hinders construction operations and affects project quality during water conservancy construction to outside the construction site. Construction drainage can be divided into foundation pit or construction site drainage. [0003] At present, submersible pumps are mostly used for pumping and lowering the water level. In the prior art, some submersible pumps are equipped with cutting knives. However, for larger debris, it is difficult to cut and still inconvenient for water delivery. Some submersible pumps have filter screens in the water inlet, but with the flow of water, some sundries accumulate on the surface of the filter screen, causing the mesh hole...

[0003] At present, submersible pumps are mostly used for pumping and lowering the water level. In the prior art, some submersible pumps are equipped with cutting knives. However, for larger debris, it is difficult to cut and still inconvenient for water delivery. Some submersible pumps have filter screens in the water inlet, but with the flow of water, some debris accumulates on the surface of the filter screen, causing the mesh holes on the filter screen to be blocked, which may easily lead to unsmooth water intake and poor use effect
