Description

Technical Field

[0001] The utility model relates to the field of antifreeze devices, in particular to a gate antifreeze device. Background Art

[0002] The gate is an important equipment of the reservoir, and is a key link in achieving flood control and flood discharge, power generation in power stations, and ensuring the safety of the reservoir. The northern region is cold in winter. If necessary measures are not taken in time, the reservoir gate is prone to ice problems, resulting in deformation and leakage of the water seal. In severe cases, the ice layer will also generate huge pressure, which will act on the hinge support through the gate and even fracture the hinge support. The lateral pressure of the ice layer will also cause gate opening accidents. Therefore, sufficient attention must be paid to the anti-freezing of the gate. In the existing technology, artificial ice breaking and electric deicing methods are mostly used. The labor cost is low, but the safety problem is more prominent, and the deicing efficiency is limited. The electric deicing method is expensive, and the technology is immature and has high requirements for equipment and related materials. Utility Model Content

The water pump sends the water flow from the side with higher water level in the reservoir to the drainage main pipe through the suction pipe, and the water flow is flushed on both sides of the gate body through the nozzle to keep the water moving and avoid freezing.

[0012] 2. When the temperature is too low and the gate body is frozen, the ice-breaking mechanism installed at the lower end of the main beam is used to break it. The buoys set on both sides of the floating plate ensure that the ice-breaking mechanism remains above the water surface and will not be affected by the water surface height, so the ice-breaking operation can be carried out continuously.
