[0002] Drilling pipe is an important tool used in oil drilling operations. It is usually composed of a drill pipe, a drill bit and other accessories. During the drilling process, the drill pipe is rotated and pushed to send the drill bit into the ground to drill rock or formation samples. During use, due to the unknown underground conditions and the mixing of soil and drilling fluid during the drilling process, mud and other debris will adhere to the outer surface of the drill pipe. When the soil is removed, it is solidified on the outer wall of the drill pipe and is not easy to clean.

The top of the end plate 27 is provided with a limiting hole 32, and the top of the arc-shaped clamping plate 30 is longitudinally fixed with a limiting guide rod 33, which longitudinally penetrates the limiting hole 32, and the surface of the limiting guide rod 33 is in contact with the hole wall of the limiting hole 32, that is, under the common limiting action of the limiting hole 32 and the limiting guide rod 33, the arc-shaped clamping plates 30 can stably move toward each other or move in the opposite direction;

[0033] The immersion assembly includes a plurality of vertically arranged electric push rods 34, which are electrically connected to the electric control box 5. The bottom end of the electric push rod 34 is vertically fixed at the bottom of the skid-mounted base 1, and a immersion tank 35 is fixed at the top of the output shaft of the electric push rod 34. The immersion tank 35 is located directly below the drill rod 4.

Therefore, the device can perform systematic cleaning operations of flushing, immersing, fine washing and flushing on the drill rod 4 in sequence, greatly improving the cleaning effect of the drill rod.

[0034] The use process of the present invention is as follows: the drill rod 4 to be cleaned is stored between the first pipe rack 39 and the second pipe rack 40. When feeding, the staff controls the pulley 44 to move on the guide rail 41 so that the drill rod 4 is placed horizontally between the two clamping plates 9, and then controls the electric push rod 8 to operate through the electric control box 5, so that the two clamping plates 9 move toward each other, so that the two ends of the drill rod 4 are inserted into the slot 10, that is, the drill rod 4 is clamped and fixed, and then the screw 29 is manually rotated to control the two arc clamping plates 30 to move toward each other, so that a number of bristles 31 fit the surface of the drill rod 4; then the user first opens the stop valve 16 on the water pumping pipe 15 connected to the cleaning water tank 12, and keeps the water pumping pipe connected to the detergent tank 13 closed. The stop valve 16 on the 15 is closed, and then the water pump 11 and the servo motor 19 are turned on to extract the cleaning water in the cleaning water tank 12, and pump it into the C-shaped water pipe 24 through the water pipe 17 and the water hose 18, and then spray it onto the drill rod 4 through the nozzle 25. When the servo motor 19 is running, it can drive the screw 20 to rotate forward and reverse, so as to drive the nozzle 25 to move horizontally and linearly reciprocatingly through the moving plate 23, so that the drill rod 4 can be flushed, and the two arc-shaped clamping plates 30 can move horizontally and linearly reciprocatingly synchronously with the moving plate 26 through the end plate 27, so that the surface of the drill rod 4 can be wiped by a plurality of bristles 31. At this time, the cleaning water after flushing the drill rod 4 can be concentrated and flowed into the immersion tank 35;

[0035] Then the electric push rod 2 34 operates, driving the immersion tank 35 to move upward, so that the drill rod 4 is immersed in the immersion tank 35 for immersion;

[0036] After immersion, the user closes the stop valve 16 on the water extraction pipe 15 connected to the cleaning water tank 12, and opens the stop valve 16 on the water extraction pipe 15 connected to the detergent tank 13, and then turns on the water pump 11 and the servo motor 19 to extract the detergent in the detergent tank 13, and pump it into the C-shaped water pipe 24 through the water delivery pipe 17 and the water delivery hose 18, and then sprays it onto the drill rod 4 through the nozzle 25. When the servo motor 19 is running, it can drive the screw 20 to rotate forward and reverse, thereby driving the nozzle 25 to move horizontally and linearly reciprocatingly through the moving plate 23, so that the detergent can be sprayed on the surface of the drill rod 4, and the two arc-shaped clamping plates 30 can move horizontally and linearly reciprocatingly synchronously with the moving plate 26 through the end plate 27, so that the surface of the drill rod 4 sprayed with the detergent can be wiped by a plurality of bristles 31, and the surface of the drill rod 4 can be finely cleaned;

[0037] After fine washing, the user opens the stop valve 16 on the water extraction pipe 15 connected to the cleaning water tank 12 again, and closes the stop valve 16 on the water extraction pipe 15 connected to the detergent tank 13, and then opens the water pump 11 and the servo motor 19 to extract the cleaning water in the cleaning water tank 12, and pumps it into the C-shaped water pipe 24 through the water delivery pipe 17 and the water delivery hose 18, and then sprays it again onto the drill rod 4 through the nozzle 25. When the servo motor 19 is running, it can drive the screw 20 to rotate forward and reverse, thereby driving the nozzle 25 to move back and forth horizontally through the moving plate 23, so that the drill rod 4 can be washed again;

[0038] After the cleaning is completed, the user controls the two clamping plates 9 to move in the opposite direction through the electric push rod 18, so that the two ends of the drill rod 4 are moved out of the two slots 10, thereby facilitating the taking and placing of the drill rod 4, and then opens the drain valve 37 to discharge the cleaned sewage collected in the immersion tank 35 through the drain pipe 36;

[0039] In summary, the device can perform systematic cleaning operations of flushing, immersion, fine washing and flushing on the drill rod 4 in sequence, thereby greatly improving the cleaning effect of the drill rod.

[0040] The above is only a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention by using the above technical solution or modify it into an equivalent technical solution.
