[0002] The main function of the oil pipe cleaning equipment is to remove oil, dust and other impurities on the surface or inside of the oil pipe to keep the oil pipe clean, ensure that the oil pipe can be used normally in the future, and improve work efficiency. Regular cleaning of the oil pipe can prevent corrosion and wear, thereby extending the service life of the oil pipe.

[0026] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Example

[0027] like Figures 1 to 11 As shown, the cleaning device for oil pipes according to the embodiment of the present invention is particularly referred to Figure 1 , Figure 2 , including a liquid storage tube 1, the upper end of which is connected with a liquid inlet pipe 11, and the lower end side wall of the liquid storage tube 1 is evenly provided with a plurality of liquid outlets 12, the liquid storage tube 1 is used to place a mixture of oil cleaning agent and water; a fixing mechanism 2 slidably connected to the outer wall of the liquid storage tube 1 for limiting the rotation of the liquid storage tube 1; a cleaning mechanism 3 arranged under the liquid storage tube 1; and a driving shaft 4 rotatably connected to the liquid storage tube 1, the driving shaft 4 passing through the liquid storage tube 1 and connected to the cleaning mechanism 3, The driving shaft 4 is used to drive the cleaning mechanism 3 to clean the inner wall of the oil pipe; wherein the cleaning mechanism 3 includes: a cleaning sheet 31 fixedly connected to the driving shaft 4, the outer end of the cleaning sheet 31 is an arc surface and is adapted to the inner wall of the oil pipe; and a scraping and knocking component 32 arranged at the outer end of the cleaning sheet 31, the scraping and knocking component 32 is used to knock the inner wall of the oil pipe and scrape off the oil stains and dirt in the pits on the inner wall of the oil pipe, and the scraping and knocking component 32 is arranged in multiple groups at the outer end of the cleaning sheet 31.

[0028] Specifically, the inner wall of the oil pipe will have holes after long-term use, and oil or other dirt will be attached and accumulated in these holes. When the inner wall of the oil pipe needs to be cleaned, the staff will fix the oil pipe, slowly extend the liquid storage pipe 1 and the cleaning mechanism 3 into the oil pipe, and then fix the fixing mechanism 2 to the outer wall of the oil pipe. At this time, the cleaning sheet 31 contacts the inner wall of the oil pipe, and then the mixed liquid of the oil cleaning agent and water is input into the inner cavity of the liquid storage pipe 1 through the liquid inlet pipe 11. At the same time, the mixed liquid is sprayed on the inner wall of the oil pipe through the liquid outlet 12. The mixed liquid contacts the oil and dirt to soften and dissolve the oil and dirt. At the same time, the rotating drive shaft 4 (the drive shaft 4 can be rotated manually or installed by the staff) The cleaning sheet 31 is driven by a driving motor (the cleaning sheet 31 is driven by a driving motor) and the cleaning sheet 31 is driven by the driving shaft 4 to rotate. During the rotation of the cleaning sheet 31, centrifugal force is generated. Then, by changing the rotation speed of the driving shaft 4, the magnitude of the centrifugal force is also changed, so that the scraping and knocking component 32 knocks on the side wall of the oil pipe under the action of the constantly changing magnitude of the centrifugal force. Under the action of the scraping and knocking component 32, the softened and dissolved oil stains and dirt can be easily separated from the holes on the inner wall of the oil pipe. At the same time, under the action of the rotation of the driving shaft 4, the cleaning sheet 31 and the scraping and knocking component 32 continuously rotate and rub against the inner wall of the oil pipe, which is beneficial to remove the oil stains and dirt on the inner wall of the oil pipe and the holes on the inner wall.

[0029] Please refer to Figure 2 , Figure 3 , Figure 4The scraping and knocking assembly 32 includes: a knocking block 322 sliding in a scraping and knocking groove 321, wherein the scraping and knocking groove 321 is opened at the outer end of the cleaning sheet 31; and a scraping and knocking spring 323 fixedly connected to the knocking block 322, wherein the two ends of the scraping and knocking spring 323 are respectively fixedly connected to the knocking block 322 and the bottom surface of the scraping and knocking groove 321.

[0030] Specifically, when the drive shaft 4 is not rotating, the scraper spring 323 is in a normal state, and the knocking block 322 is located in the scraper groove 321. When the drive shaft 4 rotates to drive the cleaning sheet 31 to rotate faster, the end of the knocking block 322 will slide out of the scraper groove 321 and contact the inner wall of the oil pipe under the action of centrifugal force. However, when the drive shaft 4 rotates to drive the cleaning sheet 31 to rotate slower, the scraper spring 323 will drive the knocking block 322 to move back, so that the knocking block 322 can knock the inner wall of the oil pipe back and forth, so that the softened and dissolved oil stains and dirt can be separated from the holes on the inner wall of the oil pipe.

[0031] Please refer to Figure 2 , Figure 5 The outer wall of the liquid storage tube 1 is provided with a slide groove 13; the fixing mechanism 2 comprises: a slider 21 sliding in the slide groove 13; a solid cover 22 fixedly connected to the slider 21, the solid cover 22 being adapted to the outer wall of the liquid storage tube 1; and a rubber ring 23 fixedly connected to the bottom end of the solid cover 22, the rubber ring 23 being adapted to be closely connected to the outer wall of the top end of the oil pipe.

[0032] Specifically, when the inner wall of the oil pipe needs to be cleaned, the staff fixes the oil pipe and then slowly extends the liquid storage pipe 1 and the cleaning mechanism 3 into the oil pipe. At this time, the solid cover 22 is tightly connected to the outer wall of the oil pipe through the rubber ring 23, and the friction force generated between the rubber ring 23 and the outer wall of the oil pipe fixes the position of the solid cover 22 and the outer wall of the oil pipe. At this time, when the drive shaft 4 rotates, it will not drive the liquid storage pipe 1 to rotate. Then, after the fixing mechanism 2 is fixed to the oil pipe, the liquid storage pipe 1 can only move in the oil pipe and cannot rotate.

[0033] Please refer to Figure 2 , Figure 6 , Figure 7 , and also includes a melting-promoting mechanism 5 arranged in the inner cavity of the liquid storage tube 1, the melting-promoting mechanism 5 includes: a heating component 51 placed near the bottom of the inner cavity of the liquid storage tube 1, the heating component 51 is used to stir the mixed liquid of the oil cleaning agent and water; wherein, the heating component 51 includes: a heating tube 511 installed in the inner cavity of the driving shaft 4; a rotating column 512 fixedly connected to the driving shaft 4, the rotating column 512 is located near the bottom end of the inner cavity of the liquid storage tube 1; and a stirring blade 513 fixedly connected to the side wall of the rotating column 512.

[0034] Specifically, when it is necessary to clean the inner wall of the oil pipe, the heating tube 511 in the inner cavity of the drive shaft 4 is turned on. At this time, the temperature of the inner cavity of the liquid storage tube 1 increases. After the mixed liquid of the oil cleaning agent and water enters the liquid storage tube 1 from the liquid inlet pipe 11, the mixed liquid will gradually heat up. At the same time, the rotation of the drive shaft 4 drives the rotating column 512 to rotate, and the rotation of the rotating column 512 drives the stirring blade 513 to stir the mixed liquid, so that the oil cleaning agent and water in the mixed liquid are more fully integrated. The more fully integrated mixed liquid is conducive to improving the cleaning ability of the mixed liquid. At the same time, it can also make the temperature of the mixed liquid more uniform, and the temperature of the mixed liquid close to the drive shaft 4 will not be high, and the temperature of the mixed liquid far away from the drive shaft 4 will not be low. Try to make the temperature of the mixed liquid flowing out of the liquid outlet 12 the increased temperature. The mixed liquid with a higher temperature can dissolve oil stains and dirt at a relatively fast speed, which is conducive to improving the cleaning effect of the mixed liquid of the oil cleaning agent and water. Then, the cleaning ability of the mixed liquid can be improved by the stirring heating component 51, and then the speed of cleaning the inner wall of the oil pipe by the cleaning mechanism 3 is improved.

[0035] Please refer to Figure 2 , Figure 6 , Figure 7 The upper end surface of the rotating column 512 is provided with an annular slope groove 5121, and the annular slope groove 5121 is inclined relative to the bottom surface of the inner cavity of the liquid storage tube 1; the melting promotion mechanism 5 also includes a foam cleaning component 52, and the foam cleaning component 52 cooperates with the rotating column 512 to remove the foam at the upper end of the inner cavity of the liquid storage tube 1; the foam cleaning component 52 includes: a defoaming cotton 521 arranged in the liquid storage tube 1, the defoaming cotton 521 is sleeved and slidably connected to the driving shaft 4, and the liquid inlet pipe 11 It is an extendable corrugated tube, and the liquid inlet pipe 11 placed in the inner cavity of the liquid storage tube 1 penetrates the defoaming cotton 521 and is fixedly connected to the defoaming cotton 521; a slope block 522 sliding in the annular slope groove 5121, and the slope block 522 is below the defoaming cotton 521; a moving rod 523 with two ends respectively fixed to the top surface of the slope block 522 and the bottom surface of the defoaming cotton 521; and a limiting rod 524 sleeved and slidably connected to the moving rod 523, and the limiting rod 524 is fixedly connected to the inner wall of the liquid storage tube 1.

[0036] Specifically, when the heating component 51 heats and stirs the mixture of the oil cleaning agent and water, foam will be generated. If there is too much foam in the inner cavity of the liquid storage tube 1, too much foam will flow out of the liquid outlet 12. Since the foam is light, it will not be able to contact the inner wall of the oil pipe too much when flowing out, thereby reducing the cleaning effect of the cleaning mechanism 3 on the inner wall of the oil pipe. Therefore, it is necessary to reduce the foam in the inner cavity of the liquid storage tube 1.

[0037] When the driving shaft 4 rotates to drive the rotating column 512 to rotate, and the rotating column 512 rotates to drive the stirring blade 513 to stir the mixed liquid, foam will be generated in the mixed liquid at the same time, and the foam will float to the upper layer of the mixed liquid. When the rotating column 512 rotates, it will drive the slope block 522 to slide in the annular slope groove 5121. Since the annular slope groove 5121 is inclined relative to the bottom surface of the inner cavity of the liquid storage tube 1, when the slope block 522 slides along the annular slope groove 5121, it will drive the moving rod 523 and the defoaming cotton 521 to move up and down. When the foam floats to the upper layer of the mixed liquid, the descending defoaming cotton 521 will absorb and decompose the foam. In this way, when the driving shaft 4 drives the stirring component 51 to heat and stir the mixed liquid of the oil cleaning agent and water, it will also drive the foam cleaning component 52 to move up and down to absorb and decompose the foam in the inner cavity of the liquid storage tube 1, thereby reducing the amount of foam flowing out of the liquid outlet 12, so that more mixed liquid flows out of the liquid outlet 12.

[0038] Please refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 The foam removal component 52 also includes: a circular pressure plate 514 fixedly connected to the top surface of the defoaming cotton 521, the size of the circular pressure plate 514 is adapted to contact with the inner cavity of the liquid storage tube 1, and part of the liquid inlet pipe 11 in the inner cavity of the liquid storage tube 1 passes through the circular pressure plate 514; and a magnetic ring 515 fixedly connected to the side wall near the bottom end of the moving rod 523, and the magnetic ring 515 is sleeved on the driving shaft 4.

[0039] Please refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 The fusion promoting mechanism 5 also includes a blocking component 53, which can control the flow rate of the liquid outlet 12 by cooperating with the foam clearing component 52; the blocking component 53 includes: a blocking ring 531 placed near the bottom end of the inner cavity of the liquid storage tube 1, and the outer diameter of the blocking ring 531 is adapted to the inner cavity of the liquid storage tube 1; a support rod 532 fixedly connected to the upper end of the blocking ring 531, and a plurality of support rods 532 are arranged circumferentially on the blocking ring 531; and a magnetic block 533 fixedly connected to the support rod 532, one end of the support rod 532 is fixedly connected to the upper end of the blocking ring 531; the other end of the support rod 532 is fixedly connected to the magnetic block 533, and the magnetic block 533 and the magnetic ring 515 can be adsorbed to each other.

[0040] Specifically, when the slope block 522 is located at the relatively highest point of the annular slope groove 5121, the magnetic block 533 is adsorbed and connected with the magnetic ring 515, and the blocking ring 531 is located at the side end of the liquid outlet 12. At this time, the blocking ring 531 blocks the liquid outlet 12. When the driving shaft 4 rotates and drives the rotating column 512 to rotate, it will drive the moving rod 523 and the defoaming cotton 521 to move up and down. The moving rod 523 moves up and down, which will drive the circular pressure plate 514, the magnetic ring 515, the magnetic block 533 support rod 532 and the blocking ring 531 to move up and down. In this process, since the circular pressure plate 514 is in adaptive contact with the inner cavity of the liquid storage tube 1, the liquid storage tube 1 will be pressed when the circular pressure plate 514 descends. 1 is squeezed downward, therefore, under the action of the circular pressure plate 514 and the blocking component 53, the liquid outlet flow rate in the liquid outlet 12 is constantly changing. When the liquid outlet flow rate of the liquid outlet 12 is relatively small, a part of the mixed liquid flowing out of the liquid outlet 12 will be sprayed on the cleaning sheet 31; when the liquid outlet flow rate of the liquid outlet 12 is relatively increased, the mixed liquid can quickly and more contact with the inner wall of the oil pipe, so that the temperature of the heated mixed liquid will not drop too much in the process of flowing out of the liquid storage pipe 1 and spraying onto the inner wall of the oil pipe, thereby making the oil stains and dirt on the inner wall of the oil pipe can be quickly dissolved, so as to improve the cleaning effect of the cleaning mechanism 3 on the inner wall of the oil pipe.

[0041] Please refer to Figure 2 , Figure 3 , Figure 4 , Fig. 9 The upper end surface of the cleaning sheet 31 is provided with an inclined surface 311, and the height of the cleaning sheet 31 gradually decreases from being away from the driving shaft 4 to being close to the driving shaft 4; the cleaning mechanism 3 also includes a scraper assembly 33, and the scraper assembly 33 is used to clean the cleaning sheet 31; the scraper assembly 33 includes: a fixed connecting rod 331 fixedly connected to the bottom end of the liquid storage tube 1, and a plurality of fixed connecting rods 331 are provided between the cleaning sheet 31 and the bottom end of the liquid storage tube 1; and a scraper rope 332 fixedly connected to the bottom end of the fixed connecting rod 331, and the scraper rope 332 is used to generate friction when the cleaning sheet 31 rotates.

[0042] Specifically, during the process of the cleaning sheet 31 cleaning the oil pipe, the cleaning sheet 31 will be stained with oil and dirt. If the cleaning sheet 31 is immersed in too much oil and dirt, the cleaning ability of the cleaning sheet 31 will be reduced. When the driving shaft 4 rotates and drives the cleaning sheet 31 to clean the oil pipe, when the driving shaft 4 rotates and drives the rotating column 512 to rotate, and then the moving rod 523 moves up and down, it will drive the circular pressure plate 514, the magnetic ring 515, the magnetic block 533, the support rod 532 and the blocking ring 531 to move up and down. When the liquid outlet flow rate of the liquid outlet 12 is relatively small, a part of the outflowing mixed liquid will be sprayed on the cleaning sheet 31. This part of the mixed liquid sprayed on the cleaning sheet 31 will be immersed in the cleaning sheet 31 along the inclined surface 311, and the oil and dirt on the cleaning sheet 31 will be dissolved. At the same time, when the cleaning sheet 31 rotates with the driving shaft 4, it will produce friction and extrusion with the scraper rope 332. Therefore, the cleaning sheet 31 can be simply cleaned by the scraper rope 332 and the mixed liquid sprayed on the cleaning sheet 31, thereby increasing the working time of the cleaning sheet 31 in the oil pipe, thereby improving the cleaning ability of the cleaning sheet 31.

[0043] To sum up, when the mixture of oil cleaning agent and water is heated and stirred by the melting promoting mechanism 5, the foam in the inner cavity of the liquid storage tube 1 will be adsorbed and decomposed at the same time, thereby reducing the amount of foam flowing out of the liquid outlet 12, so that more mixed liquid flows out of the liquid outlet 12, and at the same time, the mixed liquid can quickly and more contact with the inner wall of the oil pipe, so that the temperature of the heated mixed liquid will not drop too much in this process, and the oil stains and dirt on the inner wall of the oil pipe can be quickly dissolved, so as to improve the effect of cleaning the inner wall of the oil pipe by the cleaning mechanism 3. At the same time, when the liquid outlet flow rate of the liquid outlet 12 is relatively small, a part of the flowing mixed liquid will be sprayed on the cleaning sheet 31, which can simply clean the cleaning sheet 31, thereby increasing the working time of the cleaning sheet 31 in the oil pipe, thereby improving the cleaning ability of the cleaning sheet 31.

[0044] Please refer to Figure 2 , Figure 3 , Figure 4 , Fig. 9 , Fig.10 A throwing groove 312 is provided at the outer end of the cleaning sheet 31; the cleaning mechanism 3 also includes a throwing and stretching assembly 34 placed in the throwing groove 312, and the throwing and stretching assembly 34 is used to clean the areas in the oil pipe that are corroded on a large scale; the throwing and stretching assembly 34 includes: a throwing and stretching spring 341 fixedly connected to the bottom surface of the throwing groove 312; and a throwing and wiping sheet 342 slidingly placed in the throwing groove 312, one end of the throwing and stretching spring 341 is fixedly connected to the bottom surface of the throwing groove 312, and one end of the throwing and stretching spring 341 is fixedly connected to the throwing and wiping sheet 342.

[0045] Specifically, when the oil pipe is in use, not only will the inner wall be corroded with holes, but also a large area of ​​corrosion may occur. When the driving shaft 4 rotates to drive the cleaning sheet 31 to rotate to clean the inner wall of the oil pipe, the cleaning sheet 31 will generate centrifugal force during the rotation. When the inner wall of the oil pipe is corroded on a large area, the end of the wiping sheet 342 will move out of the throwing groove 312 under the action of centrifugal force, and then the driving shaft 4 rotates to drive the cleaning sheet 31 to rotate to clean the large area of ​​corrosion. Multiple groups of scraping and knocking components 32 can also be set on the outer wall of the wiping sheet 342 to knock on the large area of ​​corrosion, so that the scraping and knocking components 32 can clean the oil stains and dirt in the holes in the large area of ​​corrosion. Therefore, the large area of ​​corrosion in the oil pipe can be cleaned by the throwing and stretching component 34.

[0046] Please refer to Figure 1 , Figure 2 , Fig.11 , and also includes a collecting cotton net 6 detachably connected to the bottom end of the outer wall of the cleaning sheet 31, and the collecting cotton net 6 is used to collect oil or dirt that falls off during cleaning; and a cooling mechanism 7 installed at the top of the liquid storage tube 1, through which the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1 can be cooled; wherein, the cooling mechanism 7 includes a coolant tank 71 installed at the top of the liquid storage tube 1; and a heat conducting plate 72 that slides and passes through the bottom of the coolant tank 71, the upper end of the heat conducting plate 72 penetrates into the coolant tank 71, and the lower end of the heat conducting plate 72 passes through the circular pressure plate 514 and the defoaming cotton 521 in turn, and the lower end of the heat conducting plate 72 can contact the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1, and the heat conducting plate 72 is fixed to the circular pressure plate 514.

[0047] Specifically, the upper end of the collecting cotton net 6 is adapted to the inner wall of the oil pipe, and the collecting cotton net 6 can collect the grease or dirt to prevent the cleaned grease or dirt from falling and accumulating on the inner wall below, thereby avoiding increasing the difficulty of cleaning the inner wall of the oil pipe below. Specifically, when the driving shaft 4 drives the heat stirring component 51 to stir and heat the mixed liquid, more foam will be generated in the upper layer of the mixed liquid in the inner cavity of the liquid storage tube 1. At the same time, the driving shaft 4 will also drive the foam removing component 52 to remove the foam on the upper layer of the mixed liquid. At the same time, in order to further reduce the foam generated by the mixed liquid, the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1 can be cooled by the cooling mechanism 7. When the driving shaft 4 rotates, it drives the moving rod 523 and the defoaming cotton 521 to move up and down. The defoaming cotton 521 moves up and down, driving the circular pressure plate 514 and the heat conduction plate 72 to move up and down, so that the heat conduction plate 72 is always in contact with the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1, and the cooling liquid tank 71 always transfers low temperature to the heat conduction plate 72, so that the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1 can be cooled by the heat conduction plate 72, so that the foam generated by the mixed liquid in the upper layer of the inner cavity of the liquid storage tube 1 can be reduced by the cooling mechanism 7.
