When the cross section of the blade 131 in the oblique direction has a trapezoidal shape, the first end is optionally longer than the second end. The length of the first end is greater than that of the second end, which indicates that the contact length of the blade 131 and the cylinder body 11 is greater than the cutting length of the blade edge, and is beneficial to improving the connection strength of the blade 131 and the cylinder body 11;
when the cross section of the blade 131 in the oblique direction has a trapezoidal shape, the first end is optionally shorter in length than the second end. The length of the first end is smaller than that of the second end, which means that the contact length of the blade 131 and the cylinder 11 is smaller than the cutting length of the blade edge, which is beneficial to scraping sediment in a pipeline.
Optionally, the first cutting portion 13 is an annular cutting edge. If the first cutting portion 13 is an annular cutting edge, since the cutting edge of the first cutting portion 13 is disposed on the side of the first cutting portion 13 facing the first cavity, when the device for cleaning the pipeline deposit moves upward in the pipeline, the resistance of the first cutting portion 13 to scrape the deposit in the pipeline is large, and therefore, the strength requirement of the driving device is high, at this time, the first cutting portion 13 preferably has an elastic structure to reduce the resistance of the inner wall of the pipeline to the first cutting portion 13 when the first cutting portion 13 scrapes the deposit in the pipeline.
For the second cut 14: a second cutting part 14 is arranged on the edge of the second opening of the second cavity, and the cutting edge of the second cutting part 14 is arranged on the side surface of the second cutting part 14 facing the second cavity.

Alternatively, the second cutting portion 14 is an annular cutting edge, which means that the cutting edge of the second cutting portion 14 is a unitary structure, i.e. the cutting edge of the second cutting portion 14 surrounds one turn of the second opening of the second cylinder.
The second cutting portion 14 is an annular cutting edge, which can improve the cleaning strength and ensure the maximum cleaning area.
For the first cutting portion 13 and the second cutting portion 14: optionally, the diameter of the largest circle corresponding to the cutting edge of the first cutting portion 13 is greater than the diameter of the largest circle corresponding to the cutting edge of the second cutting portion 14, specifically: the diameter of the circle corresponding to the cutting edge of the first cutting portion 13 is slightly larger than the diameter of the circle corresponding to the cutting edge of the second cutting portion 14. When the first cutting portion 13 is a plurality of blades 131 and the second cutting portion 14 is an annular cutting edge, and the shape and structure of each blade 131 are the same, the diameter of the maximum circle surrounded by the cutting edges of the blades 131 is greater than the diameter of the maximum circle corresponding to the annular cutting edge of the second cutting portion 14, specifically: the diameter of the maximum circle surrounded by the cutting edges of the blades 131 is slightly larger than the diameter of the maximum circle corresponding to the annular cutting edge of the second cutting portion 14.
For the connecting rod 12: the connecting rod 12 is arranged in the first cavity, one end of the connecting rod 12 is connected with the interlayer 17, and the connecting rod 12 is used for being connected with a driving device.
After the connecting rod 12 is connected to the driving device, the driving device can drive the connecting rod 12 to move, and further drive the barrel 11 to move. Wherein, the axis of the connecting rod 12 is on the same straight line with the axis of the cylinder 11.
The application does not limit the specific connection relationship between the connecting rod 12 and the interlayer 17, and the connecting rod can be fixedly connected or detachably connected. When the one end of the connecting rod 12 is detachably connected with the interlayer 17, for example, the connecting rod can be in threaded connection, elastic buckle connection, etc.; when one end of the connecting rod 12 is fixedly connected with the interlayer 17, the connecting rod 12 and the interlayer 17 can be connected in a casting manner, so that the connecting rod 12 and the interlayer 17 are in an integrally formed structure. The other end of connecting rod 12 is used for being connected with drive arrangement to when drive arrangement during operation, can drive barrel 11 through driving connecting rod 12 and carry out reciprocating motion from top to bottom in oil pipe, specifically, the other end of connecting rod 12 can be threaded connection or buckle connection with drive arrangement.
It will be appreciated by those skilled in the art that in order to achieve the cleaning of deposits in pipes by the apparatus for cleaning pipe deposits, the maximum outer diameter of the barrel 11 should be less than the inner diameter of the pipe containing the deposits, and the drive means may drive the apparatus for cleaning pipe deposits to oscillate within the pipe, i.e. the apparatus for cleaning pipe deposits does not move linearly within the pipe.
The working process and the working principle of the device for cleaning deposits in a pipeline according to the present embodiment will be described below by taking the pipeline as an oil pipe and the first cutting portion 13 as a plurality of blades 131.
In practical application, after the connecting rod 12 is connected with the driving device, the device for cleaning pipeline deposits is inserted into an oil pipe, wherein the first opening of the cylinder 11 faces upwards, and the second opening faces downwards. The driving device drives the device for cleaning the pipeline deposit to move downwards, so that the second cutting part 14 scrapes the deposit on the inner wall of the oil pipe, and as the cutting edge of the blade 131 is arranged on the side surface of the blade 131 facing the first cavity, when the device for cleaning the pipeline deposit moves downwards, the blade 131 cannot scrape the deposit on the inner wall of the oil pipe; and because the device for cleaning the pipeline deposit moves downwards in the pipeline in a swinging mode, the second cutting part 14 is not completely contacted with the inner wall of the oil pipe, the part of the second cutting part 14 contacted with the inner wall of the oil pipe is subjected to the resistance of the deposit, and the part of the second cutting part 14 not contacted with the inner wall of the oil pipe is not subjected to the resistance of the deposit, so that the barrel body 11 is slightly inclined in the oil pipe. When the device for cleaning the pipeline deposit moves upwards along the oil pipe under the driving of the driving device, because the cutting edge of the second cutting part 14 is arranged on the side surface of the second cutting part 14 facing the second cavity, the second cutting part 14 does not scrape the deposit on the inner wall of the oil pipe, and because the cutting edge of the blade 131 is arranged on the side surface of the blade 131 facing the first cavity, the blade 131 scrapes the deposit on the inner wall of the oil pipe, and if the diameter of the circle surrounded by the cutting edges of the blades 131 is slightly larger than that of the circle corresponding to the cutting edge of the second cutting part 14, the second cutting part 14 does not obstruct the blade 131 from scraping the deposit, and when the device for cleaning the pipeline deposit moves upwards in a swinging manner in the pipeline, the probability that the blade 131 can cut the deposit is increased (because part of the deposit is scraped during the device for cleaning the pipeline deposit moves downwards, the thickness of the deposit is thinned, and the diameter of the maximum circle surrounded by the cutting edges of the blades 131 is slightly larger than that of the maximum circle corresponding to the cutting edge of the second cutting part 14, so that the blades 131 are more easily contacted with the deposit); some of the sediment scraped off by the blade 131 can fall into the first cavity through the first opening and is taken as a sample to the ground, and then a worker can analyze the components of the sample so as to clean the sample by adopting a proper chemical method or a thermal method.
In the embodiment, the first cavity and the second cavity which are mutually deviated are arranged, the first cutting part is arranged on the edge of the first opening of the first cavity, and the second cutting part is arranged on the edge of the second opening of the second cavity, so that when the device for cleaning the pipeline deposit moves downwards, the second cutting part can scrape the deposit in the pipeline, and when the device for cleaning the pipeline deposit moves upwards, the first cutting part can scrape the deposit in the pipeline, thereby improving the efficiency of cleaning the pipeline deposit; meanwhile, as part of the scraped deposits can fall into the first cavity and are taken to the ground as samples in the first cavity, workers can analyze the components of the samples, so that when the deposits are more, the pipeline deposits can be completely cleaned by adopting a proper chemical method or a thermal method, and the efficiency of completely cleaning the pipeline deposits is greatly improved. That is, the apparatus for cleaning pipe deposit in the present embodiment improves the efficiency of cleaning pipe deposit.
