Water conservancy and hydropower gate lifting device

Abstract

The water conservancy and hydropower gate lifting device comprises a gate seat, the gate seat comprises two limiting piers which are vertically and symmetrically arranged, supporting legs are vertically arranged at the top ends of the limiting piers, the supporting legs and the limiting piers form a stepped supporting platform, a transverse plate is fixedly connected between the tops of the supporting legs, and the supporting legs and the transverse plate jointly form a gate frame; a gate assembly is arranged in the gate frame; sliding grooves are formed in the supporting legs, and the sliding grooves are in sliding connection with the gate assembly. A lifting mechanism used for lifting the gate assembly is installed on the top face of the transverse plate. According to the designed gate and the corresponding lifting mechanism, multiple positioning is conducted on the gate, and the risk that after the gate is lifted or fixed to a certain position, a brake motor is damaged, and consequently the gate falls is avoided.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, and in particular, relates to a water conservancy and hydropower gate lifting device. Background technique [0002] The gate is a control facility used to close and open the water discharge (drain) channel. It is an important part of hydraulic structures. It can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. The gate is used in hydraulic engineering. It plays a vital role. In the gate, a lifting device is required to control the lifting of the gate. There are many types of lifting devices, which are roughly divided into crawler type and screw type. The screw type lifting device uses a screw rod to lift the gate. The positioning of the rod type lifting device is more accurate and the use range is wider. In the screw type lifting device, the brake motor is used as the power source, and the purpose of lifting ...

AI Technical Summary

Problems solved by technology

[0004] 1. After the gate is lifted, the brake motor is always under load. Due to the heavy weight of the gate, the brake motor is prone to fatigue failure when it is under load for a long time, which reduces the safety of the device;

[0005] 2. During the lifting process of the gate, the brake motor is prone to failure when working for a long time, resulting in the sudden fall of the gate, which is more dangerous

[0006] 3. Due to the heavy tonnage of the gate, when the gate is lowered to the required height to control the water flow, the impact of the flowing water and the sleeve and the lead screw need to be kept locked for a long time to fix the position of the gate, which is easy to cause slippage and cause the gate to fall , which will cause the sluice to be extremely unstable when controlling the water flow and pose a safety hazard
