Abstract

An over-stroke and impact preventing water drawing pipe device for a lift station comprises an upper-section water pipe (7), a lower-section water pipe (6) extending underwater and a fixing ring support (67) fixedly installed on the boundary of the upper-section water pipe (7) and the lower-section water pipe (6). A drive motor device (8) is hinged to the side, close to a water side wall (1), of the fixing ring support (67) and is in power linkage with the upper end of a thread sleeve (9) in thread fit with a screw (91). A fixing lug (62) is arranged on the side, close to the water side wall (1), of the portion near a water drawing port of the tail end of the lower-section water pipe (6).

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to an anti-overtravel and anti-collision pumping station water pipe device. Background technique [0002] In the field of water conservancy, it is often necessary to carry out pumping operations on low-lying water sources in order to lift the water up to meet the needs of agricultural irrigation. [0003] The water pumping station responsible for this kind of water pumping operation often needs to be equipped with large-diameter water pipes in order to efficiently lift water. In order to prevent the normal operation of the water pump from being destroyed by dirt, aquatic plants, etc. in the water, a metal filter screen is often arranged at the water inlet end of this water drawing pipe. Moreover, due to seasonal effects such as crops and precipitation, the water conservancy equipment of this pumping station has the characteristics of seasonal operation. During the long-term non-op...
