DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0026] First embodiment:

[0027] like Figure 1-6 As shown, the oil pipeline sludge treatment device provided by the utility model includes: a pull rope 101, the pull rope 101 can be made of an iron chain, one end of the pull rope 101 is provided with a connecting plate 103, the connecting plate 103 is provided with a rotating shaft 104, the rotating shaft 104 can only rotate on the connecting plate 103, the outer periphery of the rotating shaft 104 is provided with a brush 106, and at the same time, the rotating shaft 104 is installed on the threaded rod 102, the rotating shaft 104 can rotate around the threaded rod 102, and the other end of the threaded rod 102 is also provided with a plug 107, the diameter of the plug 107 is larger than the diameter of the pipeline 200, and the plug 107 is threadedly connected to the threaded rod 102. When in use, first fix one end of the pull rope 101 to the threaded rod 102 through a clip or a rope. The end of the pipe 200 is inserted into the pipe 200 to be cleaned along with the threaded rod 102, and then the end of the pull rope 101 moves to the other end of the pipe 200 along with the threaded rod 102, and then the plug 107 is installed at the end of the threaded rod 102, and the pull rope 101 is pulled from the other end of the pipe 200. Under the pulling force of the pull rope 101, the shaft 104 rotates, and the brush 106 contacts the inner wall of the pipe 200. When the shaft 104 drives the brush 106 to rotate, the brush 106 makes a spiral motion in the pipe 200, thereby cleaning the sludge on the inner wall of the pipe 200. When the shaft 104 moves from one end of the pipe 200 to the other end, the entire pipe 200 is cleaned.

[0028] By providing components such as a rotating shaft 104 and a threaded rod 102, the brush 106 can be rotated to clean the inner wall of the pipe 200. Compared with the existing method of driving the device to rotate via a transmission shaft, the rotating shaft 104 can be driven to rotate by pulling the pull rope 101. This is suitable for cleaning a pipe 200 with a longer length. At the same time, the device has a simple structure and can be easily carried to the outdoor environment for use.

[0029] Second embodiment:

[0030] like Figure 1-2As shown, a first scraper 108 and a second scraper 109 are fixedly provided on the pull rope 101 . The first scraper 108 and the second scraper 109 are hemispherical shell structures, and the radius of the spherical shell is slightly smaller than the radius of the pipeline 200 .

[0031] When the pull rope 101 enters the other end of the pipe 200 from one end, the first scraper 108 and the second scraper 109 fixed on the pull rope 101 move in the pipe 200 together with the pull rope 101. The sludge in the pipe 200 is in a semi-fluid state or a fluid state. Under the action of gravity, most of the sludge is concentrated in the lower half of the pipe 200. The first scraper 108 and the second scraper 109 are in contact with the inner wall of the pipe 200 and scrape out the sludge during the movement.

[0032] Third embodiment:

[0033] like Figure 2 As shown, a connecting shaft 111 is provided between the first scraper 108 and the second scraper 109. The connecting shaft 111 can be realized by an internal threaded sleeve and a screw. The threaded sleeve is installed on the back of the first scraper 108, and the screw is installed on the back of the second scraper 109, and then the two are connected by a threaded connection.

[0034] The connection shaft 111 can improve the integrity of the first scraper 108 and the second scraper 109, thereby preventing them from being misaligned with the inner wall of the pipeline 200 when moving in the pipeline 200, thereby preventing the sludge scraping effect from being deteriorated.

[0035] Fourth embodiment:

[0036] like Figure 2 As shown, the arc-shaped openings on the outer walls of the first scraper 108 and the second scraper 109 are both provided with rubber rings 110. The rubber rings 110 can improve the sealing performance between the first scraper 108 and the second scraper 109 and the inner wall of the pipe 200, thereby achieving better adhesion to the inner wall of the pipe 200 and a tighter connection, thereby making it easier to scrape out the sludge in the pipe 200 when the inner wall of the pipe 200 moves.

[0037] Fifth embodiment:

[0038] like Figure 1-2 As shown, there are two pull ropes 101, a balance plate 112 is provided on the pull rope 101, and the hook 105 is installed on the balance plate 112. The balance plate 112 can keep the two pull ropes 101 parallel to each other, so that the pulling force of the two pull ropes 101 on the connecting plate 103 is consistent, which is conducive to the stable operation of the device when in use.

[0039] Sixth embodiment:

[0040] like Figure 5As shown, a rib 113 is provided on one side of the plug 107, and the rib 113 is in a "cross" shape. The plug 107 is subjected to the pulling force from the threaded rod 102, and the middle part of the plug 107 is subjected to a large bending moment. Adding the rib 113 can improve the deformation resistance of the plug 107.

[0041] When using, Figure 6 As shown, first, one end of the pull rope 101 is fixed to one end of the threaded rod 102 by a clip or a rope, and the pull rope 101 is inserted into the pipe 200 to be cleaned along with the threaded rod 102, and then the pull rope 101 is inserted from one end of the pipe 200 to the other end. At this time, one end of the pull rope 101 moves with the threaded rod 102 to the other end of the pipe 200. At this time, the first scraper 108 and the second scraper 109 also move from one end of the pipe 200 to the other end, and scrape out the sludge in the pipe 200. Then, the plug 107 is installed at the end of the threaded rod 102, and the plug 107 is pulled from the other end of the pipe 200. The pull rope 101 is driven, and the shaft 104 rotates under the pulling force of the pull rope 101, and the brush 106 contacts the inner wall of the pipe 200. When the shaft 104 drives the brush 106 to rotate, the brush 106 makes a spiral motion in the pipe 200, thereby cleaning the sludge on the inner wall of the pipe 200. In this process, the first scraper 108 and the second scraper 109 move from one end of the pipe 200 to the original end again, and scrape the sludge on the inner wall of the pipe 200. When the shaft 104 moves from one end of the pipe 200 to the other end, the entire pipe 200 is cleaned.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
