Description

A lifting gate structure for water conservancy projects

Technical field

This application relates to the technical field related to lifting gates, and specifically discloses a lifting gate structure for water conservancy projects.

Background technique

A sluice is a low-head hydraulic structure. The gate is a control facility used to close and open the drainage channel. It is an important part of the hydraulic structure. The sluice is usually built on the banks of rivers, channels, reservoirs, and lakes. It can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc.

It is mainly composed of the bottom plate of the sluice chamber, the pier, the breast wall, the gate, the working bridge, the embankment top and the lifting mechanism. The sluice requires sufficient gravity to maintain its own stability, as well as anti-seepage and anti-scouring properties. In the process of adjusting water level and controlling flow, the gate needs to be raised and lowered. The lifting of the gate can control the opening and closing of the gate. Therefore, a lifting mechanism needs to be used.

The construction of many sluices has exerted great social and economic benefits in terms of flood control and dispatching, waterlogging removal, tide blocking and freshwater storage, agricultural irrigation, aquaculture, urban industry and residential water supply, etc. It is an indispensable water conservancy. facility. In various large-scale water supply and drainage, water conservancy and hydropower projects, the water gate lifting system used to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to achieve the opening and closing functions plays a vital role, and the existing screw The structure of the conventional gate lifting system is not stable enough, and there will be shaking during the lifting process of the gate.

The principles and effects of this basic plan are:

1. Compared with the existing technology, this device uses a symmetrical screw rod and a sleeve on the screw rod to realize the lifting or lowering of the gate on the lifting system. The traditional gate lifting system uses a separate threaded screw to realize the lifting or lowering of the gate. During the use of the threaded screw, the gate will shake during the lifting process due to the impact of the water flow. The lifting of the gate will be unstable. Long-term shaking will cause the connection of the gate to become loose.

2. Compared with the existing technology, this device is equipped with a reducer on the lifting system, and uses the reducer to reduce the speed output by the dual-axis motor, so that the lifting system can have an average and stable stability when raising or lowering the gate.

Sliding plates are symmetrically arranged on both sides of the gate for sliding connection with the door frame, making the gate more smoothly raised and lowered, and avoiding jamming when the gate is raised and lowered, which will affect the operation of the water conservancy project.

Further, the door frame is provided with a sliding groove for sliding connection with the sliding plate. A sliding groove is provided on the door frame to connect with the sliding plate to reduce friction when the gate is raised and lowered, making it easier to lift the gate and the dual-axis motor consumes less energy.

Further, several connecting plates are provided on the bottom plate. A connecting plate is provided on the base plate for connecting with the connecting groove on the gate.

Further, the bottom of the gate is provided with a connecting groove for connecting to the connecting plate. The bottom plate of a traditional lifting gate is provided with a groove for connecting to the gate. When the gate rises, there will be water in the groove, causing the gate to be unable to seal properly when it descends, affecting the normal use of the gate.

Further, the control panel is electrically connected to the biaxial motor. The control panel is electrically connected to the dual-axis motor, making it more convenient to start or shut down the motor.

Further, the connection structure includes a motor shaft, a motor gear, a reducer gear, a transmission shaft, a plurality of first bearings and a second bearing. The motor shaft is connected to the output end of the dual-axis motor, and the motor gear is arranged on the motor shaft. , the motor gear meshes with the reducer gear, the reducer gear is arranged on the transmission shaft, the first bearing is arranged at both ends of the motor shaft and the transmission shaft is arranged at one end close to the motor, the second bearing is arranged on the transmission shaft The end of the shaft away from the motor. A reducer is installed in front of the dual-axis motor. The reducer reduces the speed of the dual-axis motor so that the gate has an average and stable speed when it is raised and lowered, preventing the gate from colliding with the bottom plate or lintel when it is raised or lowered too quickly.
