An anti-freezing device using an air-water nozzle

Abstract

A freezing preventing device with air water sprayers comprises a plurality of first air water sprayers and a plurality of second air water sprayers. Each first air water sprayer comprises a first sprayer body and a first water suction pipe, wherein the water outlet end of the first water suction pipe is communicated with a fluid channel in the first sprayer body. The second air water sprayers are the same in structure. The first sprayer bodies and second sprayer bodies are installed on a main pipe. A draught fan is connected with the main pipe through an air supply pipe. The main pipe is provided with a floating barrel. The draught fan is connected with the output end of a clean energy and commercial power combined power supply device through a power cable. When the axis of the main pipe is horizontally arranged, the horizontal planes of inlets of the first sprayer bodies are located on the horizontal plane where the axis of the main pipe is located and the area above 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 sprayer bodies ranges from -45 degrees to 45 degrees, and the second air water sprayers are the same in structure. 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 present invention belongs to the field of water conservancy engineering anti -freezing device. It specially involves a anti -frozen device with gas water noble heads. It is suitable for water -building (structure) manufacturers to welcome the water side of the water side in winter, especially suitable for preventing the water surface in front of the gate. Background technique [0002] On the side of the northern aquatic construction (structure) building, the frozen effect will be affected every winter. Repeated freezing and merging cycle will lead to the destruction of concrete frozen melting and erosion of concrete and stones in the construction of the water blocking surface (structure).Reduce the durability of the building (structure).For the gate of the gate, the static ice pressure caused by the expansion of the ice sheet will cause the gate to deform, lift, and even cause structural destruction, causing the gate to unable to open and close, and sto...

AI Technical Summary

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.
