Description

Technical Field

[0001] The present invention relates to the technical field of anti-unhooking of sluice gates, in particular to an anti-unhooking device for sluice gates. Background Art

[0002] A spillway is a low-head water discharge structure that mainly uses gates to block water. It consists of a lock chamber and upstream and downstream connecting sections. The lock chamber is the main body of the spillway and is equipped with gates. The main function of the upstream connecting section is to guide the water flow into the gate evenly; the main function of the downstream connecting section is to dissipate energy and prevent impact, and guide the water flow to be safely discharged into the downstream river.

[0003] Sluice gates are important flood control and discharge equipment at hydropower stations, and the sluice gate maintenance gate is a key device used to isolate the sluice gate from upstream and downstream water flows during sluice gate maintenance. During the sluice gate maintenance process, because the gate hook is not designed with an anti-drop device, when the gate slot becomes abnormally protruding, the gate is prone to getting stuck, resulting in an unbalanced drop of the gate on both sides, and a major safety hazard of the gate unhooking. If a fixed anti-drop device is installed, the grab beam cannot be unhooked after the sluice gate maintenance gate falls into place, which will occupy power resources for a long time.

When decoupling is required, the driving motor 13 can be started again, the driving motor 13 rotates in the opposite direction, and the rotating shaft 19 is driven to rotate in the opposite direction synchronously through the transmission belt 21, thereby separating the connection between the movable connecting hook 22 and the connecting groove 4 at the top of the lifting gate 3.
