Lifting gate for water retaining during rising of water level inreservoir

Abstract

The invention discloses a lifting gate for water retaining during rising of the water level in a reservoir. The lifting gate comprises a reservoir base; a main power pump is fixedly arranged in the reservoir base; the main power pump is in power connection with a power rod; a lifting gate body is fixedly arranged on the upper side of the power rod; a gate cavity is formed in the reservoir base; the lifting gate body slides in the gate cavity; a gate sealing plate is fixedly arranged on the upper side face of the reservoir base; the lifting gate body slides in the gate sealing plate; a lifting cavity is formed in the left side of the lifting gate body; a water inlet groove is formed in the right side of the lifting gate body; and a starting device for starting the lifting gate is arranged in the water inlet groove. According to the lifting gate, ascending of a baffle can be automatically realized according to the water level in the reservoir, so that water overflow is prevented, and automatic drainage can be achieved when the water level exceeds the height of the reservoir; and lifting water retaining can be achieved again in the lifting process of an existing gate, so that a water source is further stored, and the water storage capacity and the reservoir safety of the reservoir are guaranteed.

Description

technical field [0001] The invention relates to the related field of water conservancy gates, in particular to a lifting gate for retaining water when the water level of a reservoir rises. Background technique [0002] In water conservancy projects, we often use water conservancy gates to control and manage water resources. This kind of gate is an important part of hydraulic structures. It is generally used by the gate body and embedded parts in conjunction with the hoist. Its function is , can realize the interception of water flow, control of water level, discharge of mud and sewage, etc. The general gate can only be lifted and lowered simply to control the water level and discharge the water, and the height of the gate determines the water storage capacity of the reservoir. For the continuous rise of the water level In the case of excess, the excess water can only be drained, and the excess water cannot be stored or controlled downstream.

[0002] In water conservancy projects, we often use water conservancy gates to control and manage water resources. This kind of gate is an important part of hydraulic structures. It is generally used by the door body and the embedded part in conjunction with the hoist. Its function is , can realize the interception of water flow, control of water level, discharge of mud and sewage, etc. The general gate can only be lifted and lowered simply to control the water level and discharge the water, and the height of the gate determines the water storage capacity of the reservoir. For the continuous rise of the water level In the case of excess, the excess water can only be drained, unable to store excess water, or control the amount of water downstream
