Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning devices, and in particular to a multifunctional natural gas pipeline cleaning device. Background Art

[0002] Natural gas is an extremely important energy resource, which is widely used in heating, power generation, industrial production, transportation and other fields. In the long-distance natural gas transportation, pipeline transportation has become the main mode of long-distance natural gas transportation due to its significant transportation capacity, low energy loss and high safety.

[0003] However, pipeline transportation will also cause a series of problems during long-term use, including: the inner wall of the pipeline gradually accumulates sediments and corrosion products during transportation, which will cause the pipeline cross-section to gradually narrow, thereby limiting the transportation efficiency of natural gas. Therefore, the inner wall of the natural gas pipeline needs to be cleaned regularly.

[0004] However, most of the existing natural gas pipeline cleaning devices cannot recover the impurities cleaned from the inner wall of the pipeline, and further secondary cleaning of the impurities is required, which is a relatively complicated process. In addition, the existing natural gas pipeline cleaning devices are only suitable for pipelines of a single diameter and cannot clean pipelines of multiple diameters. The device has poor compatibility, which reduces the processing efficiency of the natural gas pipeline cleaning operation. Utility Model Content

[0038] The other end of the coil 5 is connected to a plurality of electric telescopic tubes 12 evenly arranged in the circumferential direction, and a telescopic motor 13 is provided at the end of the plurality of electric telescopic tubes 12 branching from the end of the coil 5; the end of the electric telescopic tube 12 close to the inner wall of the natural gas pipeline is fixedly connected to an air suction port 14 through a flange, and the end of the air suction port 14 away from the electric telescopic tube 12 is connected to a brush 16 for cleaning impurities on the inner wall of the pipeline (see Figure 2 As shown in FIG. 1 , a water tank 17 is disposed on the top of the housing 1, and a liquid injection hole and a vent hole are provided on the top of the water tank 17. A water pump 18 is disposed at the bottom of the water tank 17, and the water pump 18 is connected to a water pipe 19 extending to the outside of the housing 1. The water pipe 19 is fixedly connected to the housing 1 through a water pipe buckle 20, and a nozzle 21 is disposed at the end of the water pipe 19 extending out of the housing 1, and the nozzle 21 sprays water onto the inner wall of the pipe.

The number of the electric telescopic tube 12, the air suction port 14 and the bristles 16 are all four.

[0040] By adjusting the telescopic and lifting distances of the electric telescopic tube 12 and the lifting platform 23, the coil 5 is placed on the central axis of the natural gas pipeline 29 to be cleaned, so that the bristles 16 can fully contact the inner wall of the pipelines of various diameters;

After the impurities pass through the electric telescopic tube 12 and the spiral tube 5, the impurities cannot enter the suction pump 9 due to the filter 11 provided at the inlet of the suction pump 9. The impurities fall into the impurity collection bin 8 due to gravity and accumulate. At the same time, the water pump 18 draws the cleaning liquid in the water tank 17 to the nozzle 21 for spraying, which assists the cleaning process and improves the cleaning efficiency.
