[0035] In the embodiment of the utility model, please refer to Figures 1 to 6 , both sides of the cylinder body 2 are equipped with support frames 21, and the outer wall of the support frame 21 is fixedly connected with the outer wall of the conveying belt 3. The side wall of the cylinder body 2 is equipped with mounting grooves 22, the inner wall of the mounting groove 22 is fixedly connected with the outer wall of the rack 62, and the inner wall of the mounting groove 22 is abutted and slidably connected with the outer wall of the sliding frame 61.

[0036] It should be noted that: when the adjusting cylinder 71 works, the end portion of the rubber ring 72 can be extruded, so that the rubber ring 72 moves outward and abuts with the inner wall of the oil well pipe, so that the inside of the oil well pipe can be blocked, and the oil stain scraped and cleaned can be accumulated at the inner bottom of the cylinder body 2. Through the setting of the support frame 21, the conveying belt 3 can be stably erected in the cylinder body 2, and the conveying belt 3 can stably drive the outer wall collection cylinder 31 to continuously and cyclically collect the oil stain accumulated at the inner bottom of the cylinder body 2.

[0037] In the embodiment of the utility model, please refer to Figures 1 to 6 The outer wall of the installation frame 51 is provided with a guide hopper 58 below the down material scraping piece 54, the outer wall of the guide hopper 58 is concave, the concave guide hopper 58 is located outside the collecting cylinder 31, and the inner wall of the guide hopper 58 is provided with an inclined groove 59.

[0038] It should be noted that: by arranging the inclined groove 59 in the guide hopper 58, during the scraping and discharging process of the down material scraping piece 54 on the inner wall of the collecting cylinder 31, the guide hopper 58 located outside the collecting cylinder 31 can collect and guide the oil stains falling from the edge of the collecting cylinder 31 during the scraping and discharging process, so that the phenomenon of the collected oil stains falling back can be reduced.

[0039] The working principle of the oil well pipeline cleaning device is as follows:

[0040] When the device is used, first, the scraping semi-ring 63 compatible with the inner wall of the oil well can be installed at the bottom of the sliding frame 61, so that the two scraping semi-rings 63 form a complete scraping ring, then the cylinder 2 is inserted into the oil well pipe, and the cylinder 2 is fixed by the derrick 1, during the insertion of the cylinder 2, the cylinder 2 with a relatively small size will not abut against the inner wall of the oil well pipe, after the fixation of the cylinder 2, the adjusting cylinder 71 can be controlled to extend, during this process, the adjusting cylinder 71 can extrude the rubber ring 72 at the end, so that the rubber ring 72 moves outward and abuts against the inner wall of the oil well pipe, so that the inside of the oil well pipe can be blocked.

[0041] Then the motor for driving the gear 611 to rotate in the driving assembly 6 can be controlled to work to drive the gear 611 to rotate, during the rotation of the gear 611, the sliding frame 61 can slide in the installation groove 22 on the outer wall of the cylinder 2 through the meshing between the gear 611 and the rack 62, at this time, the sliding frame 61 can drive the scraping semi-ring 63 at the bottom to scrape and clean the oil stains on the inner wall of the oil well pipe, at this time, the scraped and fallen oil stains can be accumulated at the bottom of the cylinder 2.

[0042] During this process, the transmission belt 3 in the cylinder 2 can be controlled to rotate, the rotating transmission belt 3 can drive the collecting cylinder 31 on the outer wall to rotate circularly, so that the collecting cylinder 31 can continuously collect the oil stains, when the collecting cylinder 31 moves upward to the position opposite to the push piece 551, the push piece 551 extruded by the collecting cylinder 31 can rotate in the inside of the adapter frame 55, during the rotation, the side of the push piece 551 away from the collecting cylinder 31 can extrude the pressure sensor b56 below, at this time, the external control terminal can control the driving cylinder 52 to extend when the pressure sensor b56 value changes is monitored.

[0043] The extended drive cylinder 52 will move the end scraper 54 to the top of the collection cylinder 31. At this time, as the collection cylinder 31 continues to rotate, when the top of the collection cylinder 31 abuts against the bottom of the scraper 54, the external control terminal will control the drive cylinder 52 to retract while monitoring the vertical change of the pressure sensor a542.

[0044] During this process, the upward pressing force of the collection cylinder 31 causes the telescopic rod 53 to retract. The compression spring 531 ensures that the scraper blade 54 always has a downward driving force, which makes the bottom wall of the scraper blade 54 fit more tightly with the inner wall of the collection cylinder 31. This allows the scraper blade 54 to scrape the oil collected inside the collection cylinder 31 more cleanly, making the oil discharge more thorough and reducing oil residue. This allows the collection cylinder 31 to circulate and collect oil in a more open state, reducing the phenomenon of the collected oil being repeatedly circulated into the oil well due to incomplete discharge.

[0045] Furthermore, during this process, the heating wire 43 can be controlled to work and a solvent can be added to the top cover 4, so that the heating wire 43 can preheat the collected oil to increase the fluidity of the oil, thus facilitating the centralized transportation and processing of the collected oil by the staff later.

[0046] After using the device, it can be removed from the well casing upwards without the need for separate disassembly and installation of the well casing. The entire operation is very convenient and quick, which improves the portability of subsequent well casing cleaning.

[0047] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
