[0023] like Figure 1-4In this embodiment, a cleaning device for logging cables includes a cleaning box body 1, a mud scraping mechanism 2, and a flushing mechanism 3. The cleaning box 1 is provided with a sludge area 11, a flushing area 12, and a water storage area 13 which are not connected to each other from front to back. The front side end of the cleaning box 1, the connection between the sludge area 11 and the flushing area 12, the connection between the flushing area 12 and the water storage area 13, and the rear side end of the cleaning box 1 are respectively provided with corresponding guide grooves 14, and a guide wheel 15 is provided in the guide groove 14. A sludge box 4 is provided in the sludge area 11 of the cleaning box 1 in a pull-out manner. The mud scraping mechanism 2 is provided in the upper part of the sludge area 11 in the cleaning box 1. The mud scraping mechanism 2 is composed of a fixed cylinder 21 and a mud scraping plate 22. The flushing mechanism 3 is composed of a high-pressure water pipe 31 and two symmetrical and coaxial arc-shaped water spray plates 32. The high-pressure water pipe 31 is installed on the upper part of the flushing area 12. The two arc-shaped water spray plates 32 are respectively connected to the high-pressure water pipe 31, and are suspended in the upper part of the flushing area 12 through the high-pressure water pipe 31. A number of high-pressure nozzles 33 are equidistantly arranged on the inner side surfaces of the two arc-shaped water spray plates 32. A water pump 34 connected to the high-pressure water pipe 31 is arranged in the water storage area 13. Two electric telescopic rods 51 are symmetrically fixed in the upper part of the water storage area 13, and a water-absorbing sponge 5 is respectively fixed at the telescopic ends of the two electric telescopic rods 51. A limiting wheel 6 is movably arranged above the guide groove 14 at the rear end of the cleaning box 1.

[0024] Through the above technical solution, when in use, the cable to be reeled up after use is inserted from the guide groove 14 at the front end of the cleaning box 1, the cable is located above the guide wheel 15, and then penetrates into the sludge scraper mechanism 2 above the sludge area 11, and then penetrates into the middle of the two arc-shaped water spray plates 32 of the flushing mechanism 3 in the flushing area 12 through the guide groove 14 at the sludge area 11 and the flushing area 12, and then penetrates into the water storage area 14 through the guide groove 14 at the flushing area 12 and the water storage area 13, so that the cable passes between the two water-absorbing sponge plates 5. Then the limiting wheel 6 is pulled up so that the cable is located between the guide wheel 15 and the limiting wheel 6 in the guide groove 14 at the rear end of the cleaning box 1. Then the cable end is connected to the external winding mechanism, and the winding mechanism rotates to wind up the cable, thereby dragging the cable to move. When the cable moves, the debris and sludge adhering to its surface are first scraped off by the scraping mechanism 2 in the sludge area 11, and the scraped debris and sludge fall into the sludge box 4 in the sludge area 11. The sludge box 4 is convenient for collecting and cleaning the debris and sludge, and the debris and sludge are collected by the scraping mechanism 2. The cable moves to between the two arc-shaped water spraying plates 32 in the flushing mechanism 3 on the flushing area 12, and the water in the water storage area 13 is pumped out by the water pump 34 and sent into the high-pressure water pipe 31, and then enters the arc-shaped water spraying plate 32, and finally sprayed out by the high-pressure nozzle 33, so as to fully flush the cable and improve the cleaning effect. After flushing, the cable moves to the top of the water storage area 13, and the cable surface is covered by the two water-absorbing sponge plates 5 under the drive of the electric telescopic rod 51, so as to wipe the water stains on the cable surface clean, so as to prevent the water stains on the surface from contacting with external dust during winding and causing pollution, thereby ensuring the cleaning effect. Finally, the cleaned and wiped cable enters the external winding mechanism to complete the winding. In order to prevent the water-absorbing sponge plate 5 from absorbing too much water during long-term work and becoming wet to affect the drying effect, the two electric telescopic rods 51 are regularly extended and retracted to drive the two water-absorbing sponge plates 5 to squeeze each other, squeeze out the water adsorbed inside, and then make the water-absorbing sponge plate 5 dry, so as to ensure the drying effect, and the squeezed water falls into the water storage area 13.

[0025] Preferably, a universal wheel 16 with a foot brake is provided at the bottom of the cleaning box 1 , and a push handle 17 is provided at the rear end of the cleaning box 1 .

[0026] Through the above technical solution, the push handle 17 cooperates with the universal wheel 16 to move the device, thereby improving the convenience during use.

[0027] Preferably: the fixed cylinder 21 in the scraper mechanism 2 is composed of a coaxial first arc sleeve 211 and a second arc sleeve 212, the top of the first arc sleeve 211 is installed in the upper part of the sludge area 11 through a fixing frame 23, the second arc sleeve 212 is located below the first arc sleeve 211, and one side of the second arc sleeve 212 is hinged to the side corresponding to the first arc sleeve 211, the second arc sleeve 212 is connected to the corresponding side of the first arc sleeve 212 away from the hinge side through a locking mechanism 24, the scraper plate 22 is composed of a coaxial first arc plate 221 and a second arc plate 222 made of rubber, the first arc plate 221 is installed inside the first arc sleeve 211, the second arc plate 22 is installed inside the second arc sleeve 212, and the front side ends of the first arc plate 221 and the second arc plate 222 are provided with conical scraping surfaces 223.

[0028] Through the above technical scheme, the first arc sleeve 211 and the second arc sleeve 212 in the scraper mechanism 2 are hinged, which is convenient for opening the fixed tube 21 to allow the cable to be inserted. After the cable is inserted, the first arc sleeve 211 and the second arc sleeve 212 are locked by the locking mechanism 24, so that the cable is located in the first arc plate 221 and the second arc plate 222 made of rubber. Through the conical scraping surface 223 at the front end of the first arc plate 221 and the second arc plate 222, the debris and sludge adhered to the surface of the cable can be quickly and effectively scraped into the sludge box 4 in the sludge area 11 through the movement of the cable. Since the first arc 221 and the second arc plate 222 are made of rubber, the scraper plate 22 is prevented from damaging the cable surface when scraping off the debris and sludge on the cable surface. At the same time, the scraper mechanism 2 plays a role of a cable guide limiter.

[0029] Preferably: the limiting wheel 6 is rotatably installed in an inverted U-shaped movable frame 61, and the two ends of the bottom of the inverted U-shaped movable frame 61 are respectively fixed with sliders 63 slidably connected to a limiting rod 62, and the two limiting rods 62 are symmetrically arranged on both sides of the guide groove 14 in the rear end of the cleaning box 1, and a limiting plate 621 is provided on the top of the limiting rod 62, and a spring 64 is sleeved in the limiting rod 62, and the spring 64 is located between the slider 62 and the limiting plate 621.

[0030] Through the above technical scheme, the setting of the limiting wheel 6 is used to cooperate with the guide wheel 15 in the guide groove 14 at the rear end of the cleaning box 1 to guide the cable and facilitate its movement. The setting of the limiting rod 62 and the spring 64 makes the inverted U-shaped movable frame 61 elastic and can move up and down, so that the limiting wheel 6 can move up and down, which is convenient for the cable to pass between the limiting wheel 6 and the guide wheel 15. At the same time, the limiting wheel 6 can be pressed above the cable to make the guidance more stable.
