Description

Technical Field:

[0001] The utility model relates to the technical field of pipeline cleaning equipment, in particular to a pipeline cleaning device convenient for collecting pipeline garbage. Background Art:

[0002] During the long-term uninterrupted operation of oil and gas pipelines, a lot of impurities will accumulate on the pipe wall, resulting in a decrease in flow velocity. In severe cases, it can lead to corrosion or even blockage. Therefore, regular inspection and cleaning of oil and gas pipelines are very necessary. At present, the cleaning work of oil and gas pipelines is completed by a pigging device, also known as a pipeline pig. The pigging device enters from one end of the pipeline and moves continuously until the impurities in the pipe wall are pushed out from the other end of the pipeline to complete the cleaning work.

[0003] The existing defect is that if the pipeline is long and the garbage accumulates continuously under the push of the cleaning plug, the resistance received by the cleaning plug also increases. However, using this method to handle garbage will affect the continuous use of the device and cause cumulative damage to the pipe wall, affecting the service life of the device and the pipeline. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a pipeline cleaning device convenient for collecting pipeline garbage to solve the problems raised in the above background art.

[0005] The utility model is implemented by the following technical solutions:

[0006] A pipeline cleaning device convenient for collecting pipeline garbage includes a pigging device. An electric push rod is fixedly arranged at the front end of the pigging device. A collecting bucket is fixed outside the front end of the cylinder body of the electric push rod. A leather cup is fixed on the outer surface of the front end of the collecting bucket. The front end of the piston rod of the electric push rod is detachably installed with a net bag. A wireless pressure sensor is fixed inside the front end of the net bag. The wireless pressure sensor is wirelessly communicatively connected with a controller. The controller is arranged at the rear end of the cylinder body of the electric push rod. The controller is electrically connected with the motor of the electric push rod.

[0007] Preferably, the leather cup is a polyurethane leather cup, and the outer surface of the leather cup fits with the inner wall of the pipeline.

[0008] Preferably, the net bag includes a first support rod, a second support rod and steel wires. One end of the first support rod is threadedly connected with the front end of the piston rod of the electric push rod. A plurality of steel wires are fixed between the other end of the first support rod and one end of the second support rod. The other end of the second support rod is internally fixed with a wireless pressure sensor. The steel wires are in a spiral structure. The maximum diameter of the plurality of steel wires after deformation is equal to the inner diameter of the collecting bucket, so that the net bag is movably placed inside the collecting bucket.

[0009] Advantages of the present utility model: By reforming the existing pigging device and adding a collection device at the front end of the pigging device, through replacing the mesh bag and repeatedly cleaning the pipeline and collecting garbage, the service life of the equipment can be extended, and the cumulative damage to the inner wall of the pipeline caused by excessive garbage accumulation can be reduced.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0014] Please refer to Figure 1-2 , the present utility model provides a technical solution for a pigging device convenient for collecting pipeline garbage:

[0015] A pigging device convenient for collecting pipeline garbage includes a pigging device 1. An electric push rod 2 is fixedly arranged at the front end of the pigging device 1. A collection barrel 3 is fixed on the outer side of the front end of the cylinder body of the electric push rod 2. A leather cup 4 is fixed on the outer surface of the front end of the collection barrel 3. The leather cup 4 is a polyurethane leather cup, and the outer surface of the leather cup 4 is attached to the inner wall of the pipeline 8.

[0016] The front end of the piston rod of the electric push rod 2 is detachably installed with a mesh bag 5. The mesh bag 5 can only be used once and should be immediately replaced after being taken out. A wireless pressure sensor 6 is fixed inside the front end of the mesh bag 5. The wireless pressure sensor 6 is wirelessly communicatively connected to a controller 7. The controller 7 is arranged at the rear end of the cylinder body of the electric push rod 2. The controller 7 is electrically connected to the motor 2.1 of the electric push rod 2.

[0017] The wire mesh bag 5 includes: a first rod 5.1, a second rod 5.2 and steel wires 5.3; one end of the first rod 5.1 is threadedly connected to the front end of the piston rod of the electric push rod 2, and a plurality of steel wires 5.3 are fixed between the other end of the first rod 5.1 and one end of the second rod 5.2. A wireless pressure sensor 6 is fixed inside the other end of the second rod 5.2. The steel wires 5.3 are in a spiral structure, and the plurality of steel wires 5.3 are elliptical after deformation. The maximum diameter of the plurality of deformed steel wires 5.3 is equal to the inner diameter of the collection barrel 3, so that the wire mesh bag 5 is movably placed inside the collection barrel 3.

[0018] The working principle is as follows: The movement of the pigging device 1 drives the electric push rod 2, the collection barrel 3 and the leather cup 4 to move synchronously. The piston rod of the electric push rod 2 is in the extended state, so that the impurities on the inner wall of the pipeline 8 are scraped off by the leather cup 4. As the leather cup 4 continuously moves forward in the pipeline 8, the garbage accumulates continuously in the pipeline 8. When the garbage accumulates to a certain extent, it will exert pressure on the wireless pressure sensor 6. When the pressure value reaches a certain value, a plurality of steel wires 5.3 in the wire mesh bag 5 will deform, making the structure become elliptical. At the same time, the controller 7 will control the piston rod of the electric push rod 2 to retract, so that the wire mesh bag 5 will push the garbage into the collection barrel 3 for collection during the recovery process, and the pigging device 1 will start to retreat along the original path to take out some of the collected garbage, thereby reducing the garbage in the pipeline 1, extending the service life of the equipment, and reducing the damage to the inner wall of the pipeline 1 caused by excessive garbage accumulation.

[0019] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
