Abstract

The invention relates to an intelligent tube cleaner with a soft framework. This pig promotes the pig through the pressure differential of medium in the pipeline and removes, sets up the draw-in groove on the leather cup and is connected with the inlay, arranges four magnet in between leather cup and the inlay, utilizes the deformation of four positions of four magnet response pipelines to reach the sensor with the signal, thereby judge inside deformation size and the position of pipeline. The framework material of the pipe cleaner is polyurethane, has elasticity and large allowable deformation, and can smoothly pass through parts such as a elbow and the like without blocking.

Description

Intelligent pipe cleaner with soft framework

Technical Field

The invention relates to a pipe cleaner, in particular to an intelligent pipe cleaner with a soft framework, and belongs to the field of pipe cleaning of pipelines.

Background

In the operation process of the oil and gas pipeline, accumulated water, dirt, impurities and the like are usually removed through a pigging so as to guarantee the conveying capacity of the pipeline. And the pipeline can be monitored and maintained through the pigging. Therefore, the pipe cleaning has important significance for guaranteeing the safe operation of the pipeline.

However, the pipe with a small diameter and a small turning radius is easily blocked during pipe cleaning, the requirement on a pipe cleaner is strict, and when the pipe has the defects of corrosion, depression and the like, the key for guaranteeing the safe operation of the pipe is to accurately obtain the deformation of the pipe and position the defect. Therefore, it is crucial to design a pig that has a high throughput and can be detected internally.

Disclosure of Invention

Aiming at the defects of the prior pipeline cleaning technology, the invention aims to provide an intelligent pipeline cleaner with a soft framework, which is used for realizing smooth cleaning of pipelines with smaller pipe diameter and small turning radius.

The invention is realized by the following technical scheme:

an intelligent soft-framework pipe cleaner comprises frameworks (1), (3), (6) and (8), sealing leather cups (2), (5), (7) and (9), a brush (4), a magnet (10), an inlay (11) and an inductor (12).

The shape of the framework (1) is of a bullet flow pattern, so that the fluid resistance of the pipe cleaner in the operation process can be effectively reduced.

The skeleton (6) is in an ellipsoidal shape, has good deformation and can smoothly pass through elbows with different curvature radiuses.

The sealing leather cup (9) and the framework (8) are integrally cast. The sealing leather cup (9) is provided with a clamping groove which is connected with the inlay (11).

The brush (3) is used for cleaning impurities in the pipeline, and the pipe cleaning effect can be enhanced.

The four magnets (10) are respectively positioned in the directions of 3 points, 6 points, 9 points and 12 points of the pipe cleaner and are arranged in an interlayer of the sealing leather cup (9) and the inlay (11). The deformation of four point positions of the pipeline is induced by four magnets, and signals are transmitted to the sensor, so that the size and the position of the deformation inside the pipeline are judged.

The framework (1), (3), (6) and (8), the sealing leather cups (2), (5), (7) and (9) and the inlay (11) are all made of polyurethane, and the density of the inlay (11) is smaller than that of the sealing leather cup (9).

The flexible framework intelligent pipe cleaner has the positive effects that the flexible framework intelligent pipe cleaner is allowed to deform greatly, is not blocked easily, can well pass through a small pipe diameter, and can detect the deformation of a pipeline.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

The structural schematic diagram of the intelligent soft-framework pipe cleaner disclosed by the invention is shown in fig. 1 and comprises frameworks (1), (3), (6) and (8), sealing leather cups (2), (5), (7) and (9), a brush (4), a magnet (10), an inlay (11) and an inductor (12).

Specifically, the framework (1) adopts a bullet flow pattern, so that the fluid resistance of the pipe cleaner in the operation process is effectively reduced. The framework (6) adopts two ellipsoidal shapes, has good deformation and can smoothly pass through elbows with different curvature radiuses. The brush (3) is used for cleaning impurities in the pipeline, and the pipe cleaning effect can be enhanced. The sealing leather cup (9) and the framework (8) are integrally cast. The sealing leather cup (9) is provided with a clamping groove which is connected with the inlay (11). Four magnets (10) are arranged in the interlayer of the sealing leather cup (9) and the inlay (11) in the directions of 3 points, 6 points, 9 points and 12 points of the pipeline pig. When the pipeline is deformed due to corrosion, depression or the like, the leather cup presses the magnet, and the magnetic sensor can record the change of the magnetic field caused by the change of the position of the magnet. The size and the position of the internal deformation of the pipeline can be judged through data processing and analysis. The frameworks (1), (3), (6), (8), the sealing leather cups (2), (5), (7), (9) and the inlay (11) are made of polyurethane, and have the characteristics of good elasticity, large allowable deformation and difficulty in blocking through parts such as a elbow and the like.
