Abstract

The embodiment of the invention relates to the technical field of water conservancy projects, and particularly discloses a water conservancy and hydropower gate lifting device with a buffering effect, which comprises a lifting mechanism, the lifting mechanism comprises a traction rope, one end of the traction rope is connected with a gate, the other end of the traction rope is wound on a winding wheel, and the winding wheel is connected with the lifting mechanism; rotation of the winding wheel is driven by a forward and reverse rotation servo motor. The buffering mechanism comprises a supporting rotating rod in linkage with the winding wheel, at least one first buffering supporting piece and at least one second buffering supporting piece are arranged on the supporting rotating rod, and the first buffering supporting piece and the second buffering supporting piece face different directions. According to the gate lifting device, the pulling rope can be used for stably lifting the gate, and when the pulling rope is broken, the buffer mechanism can buffer and support the gate which rapidly moves downwards, so that the danger is reduced.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy and hydropower gate lifting device with buffering effect. Background technique [0002] Water conservancy and hydropower gate is one of the important components of hydraulic structures. It can close the orifice of the building as needed, or open the orifice in whole or in part to adjust the upstream and downstream water levels and flow, so as to achieve flood control and irrigation. , water supply, power generation, navigation, wooden raft and other benefits, can also be used to remove floating objects, sediment, ice, etc., or provide necessary conditions for the maintenance of related buildings and equipment. [0003] For example, the patent document with the publication number of CN 111021314A discloses a water conservancy and hydroelectric gate lifting device, including a fixing frame, the fixing frame is arranged above the gate, and t...
