An anti-freezing device using a mechanical stirrer

Abstract

An anti-freezing device using a mechanical stirrer includes a plurality of mechanical stirrers. A plurality of buoys are fixed on each mechanical agitator, and adjacent mechanical agitators are connected by connectors, and a combined power supply device of clean energy and mains power supplies power to the plurality of mechanical agitators. A non-freezing area can be formed on the upstream side of hydraulic structures such as gates in the northern region, and the structure is simple and easy 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.
