Anti-freezing equipment used for rubber dam in severe cold area

Abstract

The invention discloses anti-freezing equipment used for rubber dam in a severe cold area. One electromotor of which the turning direction is controlled by a forwards and backwards rotating controller is respectively arranged on both sides of an upstream keeping a certain distance from a rubber dam, the two electromotors are connected through a river crossing wire rope, a plurality of turbulators are fixed below the steel cable and keep a certain distance from the steel cable, each turbulator comprises an ellipsoidal housing, a float bowl is respectively arranged on the upstream side and the downstream side of each ellipsoidal housing, a plurality of through holes are respectively formed in each ellipsoidal housing and face to directions of the two sides, and a vane wheel capable of rotating is arranged inside each ellipsoidal housing. Under the effects of the electromotors and the forwards and backwards rotating controllers, the turbulators on the steel wire rope can carry out repeated disturbances to the surface of a river, so as to prevent river water freezing. The anti-freezing equipment provided by the invention can prevent risks in worker operation, can run on the surface of the river, is easy for equipment maintenance and is relatively low in running cost.

Description

technical field [0001] The invention relates to an anti-freezing device, in particular to an anti-freezing device for rubber dams in severe cold regions to prevent freezing of the water surface in front of the dam. Background technique [0002] When the reservoirs in severe cold regions enter winter, the water surface will freeze, which will have a certain impact on the safety of reservoir operation. For example, freezing in front of the gate will affect the opening of the gate and affect flood discharge; freezing in front of the rubber dam will accelerate the aging of the dam material, and even puncture the rubber material, making the structure invalid. Therefore, it is very necessary to use anti-freezing equipment. At present, the main anti-freezing methods are: (1) compressed air bubble blowing method and pressure water jet method. This type of method utilizes the water convection with a slightly higher temperature in the deep layer of the reservoir to increase the tempe...

AI Technical Summary

Problems solved by technology

At present, the main anti-freezing methods are: (1) compressed air bubble blowing method and pressure water jet method. This type of method utilizes the water convection with a slightly higher temperature in the deep layer of the reservoir to increase the temperature of the surface water to prevent freezing. Submersible pumps must work reliably, or must have backup equipment, and it is more troublesome to implement, and the one-time investment is also slightly larger

(2) Electric heating method, which converts electric energy into heat energy and heats the reservoir water through metal equipment inserted into the water, which requires a large heating power, high cost, and poor fire safety
