Intelligent lifting system for river and lake channel gate

Abstract

The invention discloses an intelligent lifting system for a river and lake channel gate. The intelligent lifting system for the river and lake channel gate comprises a gate device, a lifting device and a PLC controller. The gate device comprises a bearing bracket and a gate. Grooves are formed in two sides of the bearing bracket. The gate can move perpendicularly along the grooves under the driveof the lifting device. The lifting device is arranged above an upper top plate of the bearing bracket and comprises a traction hoist, a hoist bracket, a traction rope and a rope fixing mechanism whichis arranged below the upper top plate of the bearing bracket. One end of the traction rope is fixed to the gate rope fixing mechanism, and the other end of the traction rope penetrates through a topwheel on a gate top and is connected to a traction rolling hole of the traction hoist. The traction hoist is provided with encoders, each encoder is electrically connected with a PLC controller, and the movement of the traction hoist is controlled by the PLC controllers. By means of the mode, the intelligent lifting system for the river and lake channel gate can take the place of a hydraulic lifting system commonly used at present, thereby alleviating the maintenance difficulty and improving the intelligence level of equipment and the labor efficiency.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to an intelligent lifting system for gates of rivers, lakes and rivers. Background technique [0002] In water conservancy projects, the gate is one of the important components of hydraulic structures. It can close the orifice of the building according to the needs, and can also open the orifice fully or partially to adjust the upstream and downstream water level and flow, so as to obtain flood control. , water supply, power generation and other benefits, and can also be used to intercept water flow, adjust flow, discharge sediment and floating objects, etc. Cast iron gates are usually set at the inlets and outlets of water intake and water delivery buildings, and they can be opened and closed flexibly and reliably through the gates To exert their functions and benefits and maintain the safety of buildings; the existing gate lifting structure is mostly hydraulic mechanism ...

[0002] In water conservancy projects, the gate is one of the important components of hydraulic structures. It can close the orifice of the building according to the needs, and can also open the orifice fully or partially to adjust the upstream and downstream water level and flow, so as to obtain flood control. , water supply, power generation and other benefits, and can also be used to intercept water flow, adjust flow, discharge sediment and floating objects, etc. Cast iron gates are usually set at the inlets and outlets of water intake and water delivery buildings, and they can be opened and closed flexibly and reliably through the gates To exert their functions and benefits and maintain the safety of buildings; the existing gate lifting structure is mostly hydraulic mechanism to drive the gate up and down. In the actual application process, the hydraulic gate lifting system has a relatively complicated structure and hydraulic parts are easy to age and maintenance is relatively troublesome. , and at least two people need to cooperate to complete the task when using it
