An anti-freezing device using an air spray head

Abstract

A freezing preventing device of an air sprayer comprises a plurality of first sprayers and a plurality of second sprayers. The first sprayers and the second sprayers are installed on main pipe. First sprayer ports and second sprayer ports are opposite or arranged in a back-to-back mode. A draught fan is connected with the main pipe through an air supply pipe. The main pipe is provided with a floating barrel. Electricity is supplied to the draught fan through a clean energy and commercial power combined power supply device. When the axis of the main pipe is horizontally arranged, the horizontal planes of inlets of the first sprayers and the horizontal planes of inlets of the second sprayers are located on the horizontal plane where the axis of the main pipe is located and above the horizontal plane where the axis of the main pipe is located. The angle formed between the axes of the first sprayers and the horizontal planes of the inlets of the first sprayers ranges from -45 degrees to 45 degrees, and one side of each second sprayer is the same. The non-frozen area can be formed on the upstream side of a gate and other hydraulic structures in the northern area, and equipment is convenient to maintain.

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 an air nozzle, which is suitable for anti-freezing in winter on the water-facing side of hydraulic constructions (structures) of water conservancy projects. 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 the failure of the water stop.

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.
