Therefore, the underground oil pipe cleaning machine provided by the invention has the advantages that the cleaning efficiency of the oil pipe 44 is improved, the time and the labor are saved, the cleaning cost is reduced, and the requirement of environment-friendly operation can be met.
Further, the two winding rollers are both sleeve-shaped and respectively comprise a roller (1) section 9 and a roller (2) section 11, the two winding rollers are coaxially arranged, a middle partition plate 10 perpendicular to the axes of the winding rollers is arranged between the two winding rollers, and two end partition plates, namely a left end partition plate 7 and a right end partition plate 13, are respectively arranged at two ends of the two winding rollers which are deviated from each other; the middle clapboard 10 and the two end clapboards have a limiting effect on the steel wire rope and the water conveying pipe 12; the double-roller radio-cassette player further comprises a motor 33, a bracket 30, a rotating shaft 5 and a transmission device, wherein the rotating shaft 5 is installed on the bracket 30, the rotating shaft 5 penetrates through the centers of the two winding rollers and is connected with the two winding rollers, the motor 33 drives the winding rollers to rotate forward or backward through the transmission device, more specifically, a speed reducer 32 is further arranged between the motor 33 and the transmission device, a driving gear 31 in the transmission device is connected to an output shaft of the speed reducer 32, a driven gear 14 in the transmission device is integrated on a right-end partition plate 13, the driven gear 14 drives the right-end partition plate 13 to rotate, and then a section 9 of the winding roller (1) and a section 11 of the roller (2) are driven to rotate simultaneously.
The cleaning is divided into two steps, in the first step, the water delivery pipe 12 is wound and arranged on the section of the winding roller (2) when the motor 33 rotates forwards; the inversion enables the water pipe 12 to be fed downhole to a predetermined depth; and cleaning, fixing the water delivery pipe 12 on the roller (2) section 11 by using a hoop after cleaning is finished, and then starting to take up and pay off the steel wire rope 8. When the motor 33 rotates reversely, the steel wire rope 8 is wound and arranged on the section 9 of the winding roller (1); and when the steel wire rope 8 is positively rotated, the steel wire rope is conveyed to a preset depth in the well.
Further, the winding device comprises two wire arranging devices, namely a steel wire rope wire arranging device 22 and a water conveying pipe wire arranging device 26, wherein the water conveying pipe 12 and the steel wire rope 8 pass through the two wire arranging devices respectively and are wound on the two winding rollers in sequence, and the two wire arranging devices are indirectly driven by a motor 33; the wire arranging device and the roller are synchronously carried out. And an additional motor is not needed, so that the utilization rate of resources is improved.
Further, in order to prevent the 'top up' accident ('top up', that is, the bailer 24 is stuck or broken to the top up to the top pulley), a depth sensing device 4, a sensing contact and a warning device 15 are specially arranged. The depth sensing device 4 is connected with the warning device 15 through an electric wire, the sensing device is fixedly arranged on the left side of the winding roller, a sensing contact makes circular motion along with the rotation of the end partition plate, the circular motion is converted into the depth and the lifting height of the bailer 24 after being recorded, the depth and the lifting height are converted into electric signals, the electric signals are transmitted to the warning device 15, and the warning device 15 sends out a warning signal which can be sensed by an operator after receiving the electric signals; in addition, a hand brake 6 is further arranged on the rotating shaft 5, the hand brake 6 is used for stopping rotation of the rotating shaft 5, the process needs to be carried out manually by an operator, the motor 33 stops working immediately after the operator receives a signal indication, and the hand brake 6 is used for stopping rotation of the rotating shaft 5, so that the liquid scooping device 24 or the inner wall cleaner 25 is prevented from sliding downwards automatically.
Furthermore, when the liquid is fished, in order to prevent the steel wire rope 8 from losing control due to gravity drooping, the machine adopts a self-control motor, a discharge resistor is additionally arranged, and the discharge resistor is arranged in the distribution box 18.
Further, there is a certain design gap between the depth sensing device 4 and the sensing contact.
