[0003] The Chinese utility model CN211498761U discloses a water conservancy and hydropower gate slot antifreeze device, which uses a spiral blade to drive the water near the gate to prevent the water from freezing. The application of the device effectively improves the usability of the device, but the water conservancy and hydropower gate slot antifreeze device still has the following problems in use:

[0004] The antifreeze device for the gate slot of the water conservancy and hydropower gate needs to rotate the spiral blade to realize the rotation of the water flow to prevent the gate guide channel from freezing. However, when the gate is closed, the water flow cannot flow, and the gap between the gate and the inner wall of the guide channel is easily frozen, affecting the lifting of the gate.

At the same time, hot water can be continuously input into the joints through a number of water injection holes, greatly improving the smoothness of sliding. BRIEF DESCRIPTION OF THE DRAWINGS
