Freezing preventing device with mechanical stirrers

Abstract

A freezing preventing device with mechanical stirrers comprises the multiple mechanical stirrers. Each mechanical stirrer is fixedly provided with a plurality of floating barrels. The adjacent mechanical stirrers are connected through connectors. Electricity is supplied to the mechanical stirrers through a clean energy and commercial power combined power supply device. The non-frozen area can be formed on the upstream side of gates and other hydraulic structures in the northern area, and the freezing preventing device is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the field of anti-freezing devices for water conservancy projects in winter, and in particular relates to an anti-freezing device using a mechanical agitator, which is suitable for the water-facing side of hydraulic structures (structures), and is especially suitable for preventing the water surface from freezing in front of gates. Background technique [0002] On the water-facing side of hydraulic structures (structures) in the north, they are subjected to freezing every winter. Repeated freeze-thaw cycles will lead to damages such as concrete freeze-thaw denudation and loosening of protective blocks on the water-retaining surface buildings (structures). Reduced the durability of buildings (structures). For the gate part, the static ice pressure caused by the expansion of the ice sheet will cause the gate to deform, lift up, and even cause structural damage, resulting in the failure of the gate to open and close normally and t...

Problems solved by technology

[0002] On the water-facing side of hydraulic structures (structures) in the north, they are subjected to freezing every winter. Repeated freeze-thaw cycles will lead to damages such as concrete freeze-thaw denudation and loosening of protective blocks on the water-retaining surface buildings (structures). Reduced durability of buildings (structures)

For the gate part, the static ice pressure caused by the expansion of the ice sheet will cause the gate to deform, lift up, and even cause structural damage, resulting in the consequences of the gate being unable to open and close normally, and water sealing failure.

Currently commonly used anti-freezing measures, such as compressed air method, submersible pump method, heat pipe anti-freezing method and manual slotting ice-breaking method, etc., generally have many problems such as high energy consumption, dangerous operation and difficult maintenance during operation.
