Description
Technical Field
The invention relates to the technical field of rust removal and maintenance of building pipelines, in particular to a rust removal and maintenance system and a rust removal and maintenance method for the inner wall of a water supply metal pipeline of a large building.
Background

The common pipe materials of the building water supply and drainage system comprise two main types of metal pipes and nonmetal pipes, and the cast iron pipe has the characteristics of high strength, high working pressure bearing and good sealing performance, and is widely applied to external water supply pipes. However, as the pipeline is made of cast iron, rust is easy to generate on the inner wall of the pipeline after long-time use, and the pipeline is corroded, so that the service life of the pipeline is influenced.
At present, the rust removal, scale removal and inner wall corrosion prevention treatment of the inner wall of a pipeline are carried out by the following methods of 1 mechanical method. 2, chemical agents are filled into the pipeline and stored for a period of time, so that scaling in the pipeline is softened and falls off, and the scale removal purpose is achieved. 3. The vibration method is to vibrate the pipeline (e.g. strike the pipeline) to remove rust and scale in the pipeline and achieve the descaling effect. 4. Electromagnetic method, prevent scaling and descaling of the inner wall of the pipeline by electromagnetic field. 5. The lining method prevents further corrosion of the inner wall of the pipeline by lining the inner wall of the pipeline with a plastic pipe. 6. The air flow method adopts high-pressure air and water to remove rust, scale and protect the inner wall of the pipeline. Although the methods are widely applied and have good social and economic benefits, the methods have the respective defects, such as rust removal, scale removal and inner wall corrosion prevention of large-caliber pipelines by using an airflow method, a large-capacity air storage tank (bag) is required to be arranged so as to ensure sufficient air quantity in the cleaned large-caliber pipelines, but the cost of rust removal and scale removal is high, the construction process is complex, and the operations of rust removal, scale removal and corrosion prevention are very inconvenient. At present, for a large-caliber pipeline, rust and scale bonded on the inner wall of the pipeline are generally scraped by adopting a mechanical method.

However, the structure that a plurality of swinging rods act simultaneously is adopted, and the inner wall of the pipeline is subjected to 'indiscriminate' rust removal, namely, the positions with rust and the positions without rust are subjected to rotary friction rust removal, so that the rust removal is relatively comprehensive, but the positions without rust are rubbed during the rust removal, and the positions without rust can be damaged.

The design concept of the embodiment 2 is that, because the invention adopts the shoveling rust removing mode, each arc-shaped rust shoveling plate is arranged at intervals, rust removing can be carried out only on the rust part of the inner wall of the pipeline, and damage can not be caused on the inner wall of the pipeline at the rust-free part, however, gaps exist between the arc-shaped rust shoveling plates, if rust exists in the gaps, the rust can not be shoveled, therefore, through the arrangement, the position of the arc-shaped rust shoveling plate is changed through the rotation of the second driving motor, and the rust between the original arc-shaped rust shoveling plates is shoveled, so that omission is avoided.
The working method of the embodiment comprises the following steps:
(1) Clamping and fixing the pipeline;
(2) When the detecting element detects rust on the inner wall of the pipeline, the rust removing and spraying mechanism does not move forward any more, and the rust removing and spraying mechanism removes the detected rust through reciprocating motion;
(3) After the rust is removed, spraying paint in real time and scraping;
(4) Driving the rust removal paint spraying mechanism to continuously move forward in the pipeline;
(5) Repeating the steps (1) - (4) until the rust removal maintenance of the inner wall of the whole pipeline is completed, and driving the rust removal paint spraying mechanism to reset.
In the step (2), when the detecting element detects rust on the inner wall of the pipeline, the rust removing and curing position is changed by rotating the rust removing and spraying mechanism.
Of course, the above description is not intended to limit the invention to the particular embodiments disclosed, but the invention is not limited to the particular embodiments disclosed, as variations, modifications, additions or substitutions within the spirit and scope of the invention will become apparent to those of ordinary skill in the art.
