Description

Technical Field

[0001] The invention relates to the technical field of pipeline rust removal, in particular to an inner wall rust removal device for maintaining a hydraulic water delivery pipeline. Background Art

[0002] The main reasons for rust on the inner wall of water conservancy and water supply pipelines include microbial corrosion, post-precipitation phenomenon and environmental factors. Under certain conditions, the inner wall of the pipeline becomes a place for microbial reproduction and growth. The breeding of microorganisms can accelerate the corrosion of metals. Metal ions (such as iron, manganese, calcium, magnesium ions) and microflocs in the water are deposited on the inner wall of the pipeline to form sticky sediments. These sediments not only affect the water quality, but also provide conditions for the reproduction of microorganisms such as iron bacteria, thereby accelerating the corrosion of the pipeline. The environment in which the water supply pipeline is located, such as the continuous adhesion of impurity particles in the water, the presence of chloride ions, the attachment of foreign matter in the water, insufficient space reserved at the pipeline connection, material quality problems, etc., will accelerate the corrosion and rust of the pipeline. After the inner wall of the water conservancy and water supply pipeline is rusted, it is necessary to use a rust removal device for rust removal. The main function of the rust removal device is to remove rust and debris on the inner wall of the pipeline to restore it. Cleaning and smoothing the pipeline improves the service life and safety of the pipeline. After removing rust and debris, the inner wall of the pipeline becomes cleaner, reducing the breeding environment for bacteria and other microorganisms, which is conducive to maintaining the sanitary conditions of the pipeline system. The rust removal device can remove rust and debris, increase the service life of the pipeline, improve fluid transmission efficiency, reduce energy consumption, and maintain sanitary conditions. The common water conservancy water pipeline inner wall rust removal device on the market will produce other substances in the water pipeline. Other substances and removed metal powders will flow outward through the middle position of the device, but these substances or metal powders are easy to remain in the center of the device, affecting the service life, and when removing rust, it will generate a rotational force, which is easy to cause the device body to rotate together, affecting the rust removal efficiency, and also causing the line to be entangled. When the device is taken out, the fluidity is poor, affecting the use. Summary of the invention

After pulling the traction rope, the force-bearing rod assembly moves backward inside the long groove, and the force-bearing rod assembly drives the sliding assembly to move backward together. The sliding assembly slides in contact with the force-bearing assembly through the inclined groove. Since the contact surface is an inclined structure, it pulls the force-bearing assembly and the pulling assembly moves inward, pulling the flip arm to flip and break away from the contact with the inner wall of the pipe, so that the device body can be quickly pulled out, thereby improving the removal efficiency.
