[0002] Gas pipeline cleaning is a crucial step in ensuring the safe and efficient operation of pipelines. By removing accumulated impurities, liquids, or corrosion products from the pipelines, risks such as blockages and corrosion perforations can be effectively prevented, extending the service life of the pipelines.

[0003] A prior art (publication number CN215466777U, publication date 2022-01-11) discloses an anti-clogging pig for gas pipelines, comprising a pig end, connecting columns, a motor, a rotating shaft, and anti-clogging scrapers. The pig end includes several parallel baffles. There are two pig ends connected by several connecting columns, which are evenly arranged around the axis of the pig end. The motor is located between the two pig ends and drives the rotating shaft to rotate. There are two rotating shafts and two anti-clogging scrapers. The two rotating shafts pass through the center of the two pig ends, and the two anti-clogging scrapers are fixed to the ends of the two rotating shafts. The motor drives the anti-clogging scrapers to rotate through the rotating shafts, and the ends of the anti-clogging scrapers are in close contact with the outermost baffle of the pig end. This anti-clogging pig for gas pipelines can prevent the pig from getting stuck.

[0004] Existing pipe cleaning technology can prevent the pig from getting stuck, but it cannot adjust the size of the equipment according to the diameter of the pipeline during the movement process. The device has poor adaptability and can only be used for pipelines of a single diameter.

[0005] Therefore, we propose a pipeline cleaning device for residential gas construction to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a pipeline cleaning device for gas construction in residential areas, so as to solve the problem mentioned in the background art that the size of the device cannot be adjusted according to the diameter of the pipeline, the device has poor adaptability, and it can only be applied to pipelines of a single diameter.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipeline cleaning device for residential gas construction, comprising a pipeline body, an openable and closable outer cover plate provided on the outer side of the pipeline body, and the cleaning device placed on the pipeline body through the open outer cover plate. The cleaning device includes a fixed shaft, and a threaded rod is rotatably connected to the inner end of the fixed shaft. An adjustment mechanism is provided between the outer side of the threaded rod and the outer side of the pipeline body. The adjustment mechanism positions the cleaning device by moving the position of the limiting rollers it contains. A gas supply mechanism is also provided on the outer side of the pipeline body. The gas supply mechanism cleans the cleaning device by changing the gas content stored inside the gas supply bladder it contains.

[0008] Furthermore, a pull rope is fixedly connected to one end of the fixed shaft connected to the threaded rod, and the pull rope passes through the center of the fixed shaft and the threaded rod and extends outward, so that the pigging equipment can be moved by pulling the threaded rod.

[0009] Furthermore, the adjustment mechanism includes an internal threaded sleeve, which is threadedly connected to the outside of the pipe body, and a rotating plate is hinged to the outer end of the internal threaded sleeve. The rotating plate is arranged in three sets in a ring array about the center point of the internal threaded sleeve.

[0010] Furthermore, an auxiliary plate is hinged to the outer side of the fixed shaft, and the positions of the auxiliary plate and the rotating plate correspond one-to-one. The other end of the rotating plate is hinged to the auxiliary plate, and the auxiliary plate and the fixed shaft form a rotating structure through the rotating plate.

[0011] Furthermore, an adjustment plate is hinged to the outer end of the auxiliary plate, and both ends of the adjustment plate are fixedly connected with limiting rollers for assisting the movement of the pigging equipment.

[0012] Furthermore, the gas supply mechanism includes a connecting plate, which is fixedly connected to the center of the outer side of the adjusting plate. The connecting plate has an arc-shaped structure when viewed from the side, and cleaning brushes for cleaning the pipe wall are fixedly connected to the outer side of the connecting plate.

[0013] Furthermore, an air supply airbag is fixedly connected between the lower surface of the connecting plate and the fixed shaft, and an air jet hole is opened on the upper surface of the connecting plate, and the air jet hole is connected to the air supply airbag.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A limit roller is installed. The position of the limit roller is adjusted by an adjustment mechanism so that the outer wall of the limit roller abuts against the inner wall of the pipe. The limit roller improves the ease of moving the equipment by pulling the rope, and at the same time ensures that the equipment can move stably along the inside of the pipe, thereby improving the cleaning effect.

[0016] 2. When the device is placed inside the pipe, the user manually rotates the threaded rod to move the internal threaded sleeve synchronously. The rotating plate then contacts the auxiliary plate, causing the auxiliary plate to rotate until the limiting roller at its end is in contact with the inner wall of the pipe. By moving the position of the limiting roller, the equipment can be quickly installed inside the pipe that needs to be cleaned. The size of the device can be adjusted as needed to further improve its adaptability.

[0017] 3. A connecting plate is provided on the outside of the adjusting plate. When the adjusting plate is moved into position, it can drive the connecting plate to move synchronously. At this time, the connecting plate can drive the cleaning bristles on its side to contact the pipe wall. When the equipment moves under the traction of the pull rope, the cleaning bristles can clean the inner wall of the pipe, thereby realizing the pipe cleaning operation.

[0018] 4. After the equipment cleaning is completed, rotate the threaded rod in reverse. At this time, the adjusting plate can drive the connecting plate to move to the side of the fixed shaft, thereby completing the disassembly and removal of the equipment. At the same time, during the movement, the adjusting plate can squeeze the air supply bag, causing the air supply bag to deform. The gas stored inside can be ejected outward through the air jet hole. The ejected gas can perform preliminary cleaning of the cleaning brush bristles, improving the subsequent cleaning efficiency of the cleaning brush bristles. Attached Figure Description
