[0009] Preferably, the ends of the plurality of connecting rods away from the input pipe are fixedly connected to the side wall of the support plate, and the support plate has an installation hole inside, with the inner wall of the installation hole abutting against the outer wall of the adapter pipe.

[0010] Preferably, an adapter is fixedly installed at the end of the input pipe away from the connecting plate, and the adapter is provided with an inlet pipe communicating with it.

[0011] Preferably, the scraper disc is provided with multiple discs.

[0012] Compared with related technologies, the oil scraper for the inner wall of oil tubing provided by this utility model has the following beneficial effects: 1. When in use, this utility model uses high-pressure water spray, which not only reduces the resistance of oil stains to the movement of the scraper ring, but also washes away the oil stains after scraping, reducing the probability of oil stains accumulating in front of the scraper and causing blockage, thus making the movement of the scraper ring smoother.

[0013] 2. By setting up a cleaning nozzle on the other side of the scraper, after the scraper moves inside the oil pipe and completes the scraping and cleaning of the oil stains, the high-pressure water sprayed by the cleaning nozzle can assist in rinsing the inside of the oil pipe, eliminating the need for a secondary independent rinsing and cleaning operation by the staff. Therefore, the cleaning effect of this device can be improved. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 4This utility model provides an oil pipe inner wall scraper, which includes: an input pipe 1, a connecting plate 12 communicating with the inside of the input pipe 1 fixedly installed at one end of the input pipe 1, and a support frame 31 fixedly connected to the side wall of the connecting plate 12 away from the input pipe 1, a support plate 3 fixedly connected to the end of the support frame 31, a scraper 2 movably connected on the support plate 3, and a scraper ring 21 fixedly installed on the outer wall of the scraper 2; a connecting pipe 13 communicating with the side wall of the connecting plate 12 fixedly installed, and a plurality of communicating flushing nozzles 131 fixedly installed on the connecting pipe 13; a plurality of annularly distributed cleaning nozzles 121 fixedly installed on the outer wall of the connecting plate 12, and the cleaning nozzles 121 communicating with the inside of the connecting plate 12.

[0019] It should be noted that during use, external water can flow into the connecting plate 12 and the transfer pipe 13 through the inlet pipe 111 and the input pipe 1, and then be sprayed outward through the flushing nozzle 131 on the transfer pipe 13. At this time, the flushing nozzle 131 can spray the external water towards the front of the scraper plate 2. The high-pressure water spray can not only reduce the resistance of oil stains to the movement of the scraper ring 21, but also wash the oil stains after scraping, reducing the probability of oil stains accumulating in front of the scraper plate 2 and causing blockage. Therefore, the movement of the scraper plate 2 can be made smoother. Furthermore, during this process, the cleaning nozzle 121, which is connected to the connecting plate 12, can also spray water. The high-pressure water sprayed by the cleaning nozzle 121 can assist in rinsing the inside of the oil pipe, thereby making the inside of the scraped oil pipe cleaner. This synchronous rinsing method eliminates the need for staff to perform a secondary independent rinsing and cleaning operation, thus improving the cleaning effect of the device.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 4 Multiple annularly distributed docking ears 32 are fixedly installed on the side wall of the support plate 3. A docking rod 22 is inserted inside the docking ear 32, and the docking rod 22 is fixedly connected to the docking ear 32 by a nut. The ends of the multiple docking rods 22 away from the input pipe 1 are fixedly connected to the side wall of the support plate 3. The support plate 3 has an installation hole 33 inside, and the inner wall of the installation hole 33 abuts against the outer wall of the adapter pipe 13. An adapter 11 is fixedly installed on the end of the input pipe 1 away from the connecting plate 12, and the adapter 11 has an inlet pipe 111 connected to it. The scraper plate 2 has multiple... It should be noted that: with the setting of various specifications of scraper 2, when using it, the staff can select the appropriate scraper 2 according to the oil pipe to be cleaned, so that the outer wall of the scraper ring 21 can smoothly abut against the inner wall of the oil pipe to scrape and clean the oil stains on the inner wall of the oil pipe; the material of the scraper ring 21 can be PTFE or silicone with good wear resistance and strong flexibility.

[0021] Furthermore, the inlet pipe 111 can be made of a rubber tube with supporting strength. When the operator holds and transports the inlet pipe 111, the rubber tube with supporting strength can prevent the inlet pipe 111 from bending and accumulating inside the oil pipe during the transportation process, thus achieving stable transportation of the device. Meanwhile, by abutting the mounting hole 33 inside the support plate 3 with the adapter hole, after the scraper 2 is installed on the support plate 3, a complete sealing plate can be achieved. Then, when scraping, the scraped oil stains can be pushed and cleaned, thus making the pushing and discharge of oil stains smoother.

[0022] The working principle of the oil scraper on the inner wall of the oil pipe provided by this utility model is as follows: When using this device, the operator can select a scraper 2 that matches the specifications of the inner wall of the oil pipe, insert the connecting rod 22 on the outside of the scraper 2 into the connecting ear 32 and then fix it with bolts to complete the installation of the scraper 2. After the scraper 2 is installed, the scraper 2 can be inserted into the oil pipe from the end of the oil pipe by holding the input pipe 1. Then, the external water source can be turned on, allowing water to flow into components such as the input pipe 1 and the connecting plate 12 through the inlet pipe 111. The water entering the connecting plate 12 will then flow into the corresponding flushing nozzle 131 through the transfer pipe 13, and flush the oil stains inside the oil pipe through the flushing nozzle 131. At this time, the high-pressure water sprayed from the flushing nozzle 131 will pre-wash and disperse the oil stains in front of the scraper 2 and scraper ring 21, reducing the probability of oil stains clumping. As a result, when the operator holds the inlet pipe 111 to transport the scraper 2, the obstruction caused by the oil stains to the movement of the scraper ring 21 and scraper 2 can be reduced, thereby allowing the scraper ring 21 to move and clean more stably. During the process of scraping and cleaning oil stains by the scraper ring 21, the high-pressure water source at the spray point can also rinse the oil stains scraped off by the scraper ring 21, thereby reducing the resistance caused by the accumulation of scraped oil stains on the outer wall of the scraper disc 2 and the movement of the scraper disc 2, thus making the operation of the operator more labor-saving. Once the scraper ring 21 has finished scraping and cleaning the inner wall of the oil pipe, the high-pressure water source sprayed by the cleaning nozzle 121 behind it can rinse the area after the oil pipe has been scraped. This can improve the cleanliness of the inner wall of the oil pipe after scraping, eliminating the need for staff to perform a second independent rinsing of the oil pipe, thereby improving the user experience of this device.

[0023] 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.
