DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] Example: See Figure 1-5 The utility model provides a technical solution: an automatic central tube cleaning machine, including a central tube cleaning machine, wherein two sets of frames 1 are arranged at the top and the bottom of the central tube cleaning machine, the frames 1 at the top and the bottom are connected by a plurality of cleaning brush mounting frames 4 to form two U-shaped frames, the two U-shaped frames are connected by a quick-release screw 6 to form a rectangular frame, guide fixed pulleys 5 are installed at the four corners of the rectangular frame, the guide fixed pulleys 5 are fixed to the fixing frames at the four corners of the rectangular frame by screws and nuts, the contact force between the guide fixed pulleys 5 and the central tube 15 is adjusted by adjusting the extension distance of the screw, power roller plates 2 are installed at both ends of the rectangular frame, and two cleaning brush devices 3 are installed on the four sides of the rectangular frame.

[0019] The cleaning brush device 3 is installed on the rectangular frame by bolts. The cleaning brush device 3 consists of a brush fixing plate and a brush. The brush can be a plastic brush or a metal brush. The brush fixing plate is adjusted in position by a screw and a nut to adjust the contact force between the brush and the central tube 15.

[0020] The power roller plate 2 is installed on the rectangular frame by bolts. The power roller plate 2 is composed of a power roller mounting plate 7, a seat bearing 8, a rubber-coated power roller 9, a synchronous belt 10, a synchronous pulley 11, a rigid nitrogen spring 12, a drive motor 13 and a double-output shaft reduction box 14.

[0021] The seat bearing 8 is installed on the four corners of the power roller mounting plate 7 by bolts. The rubber-coated power roller 9 is installed on the seat bearing 8 at the top and bottom of the roller mounting plate 7. A belt groove is provided at one end of the rubber-coated power roller 9. A synchronous belt 10 is provided on the belt groove of the rubber-coated power roller 9. The synchronous belt 10 passes through the rectangular groove on the power roller mounting plate 7 and is connected to the synchronous pulley 11 on the back of the power roller mounting plate 7. The synchronous pulley 11 is connected to the double-output shaft reducer 14 through a connecting shaft, and a drive motor 13 is installed on the double-output shaft reducer 14.

[0022] The double-output shaft reduction box 14 is installed on the back of the power roller mounting plate 7 by bolts. Rigid nitrogen springs 12 are installed at the four corners on the back of the power roller mounting plate 7. The power roller mounting plate 7 is fixedly connected to the cleaning brush mounting frame 4 through the rigid nitrogen spring 12. The distance between the two U-shaped frames can be adjusted by the quick-release screw 6, thereby adjusting the distance between the two power roller plates 2. The power roller plates 2 are brought close to each other to adjust the extrusion force between the rubber-coated power roller 9 and the center tube 15, so that the rigid nitrogen spring 12 is in a compressed state, thereby generating an outward thrust on the rubber-coated power roller 9, thereby ensuring that the rubber-coated power roller 9 and the concave surface of the center tube 15 can fit tightly.

[0023] The center tube cleaning machine is sleeved on the center tube 15, and a control box is installed on the center tube cleaning machine. A single-chip microcomputer is installed in the control box. The single-chip microcomputer is connected to the remote control via Bluetooth or infrared connection. The single-chip microcomputer is also electrically connected to the drive motor 13, and the drive motor 13 is connected to an external power supply. The remote control is used to control the single-chip microcomputer to start the forward and reverse rotation of the drive motor 13, thereby realizing wireless remote control.

[0024] Working principle: A central tube automatic cleaning machine. When the equipment is working, the central tube cleaning machine is placed on the central tube 15, so that the two power rollers are embedded in the concave surface in the middle of the central tube 15. Figure 4-5 As shown. By adjusting the tightness of the quick-release screw 6, positive pressure is added between the rubber-coated power roller 9 and the center tube 15. As the pressure increases, the rigid nitrogen spring 12 is compressed to maintain a stable pressure on the rubber-coated power roller 9 and the center tube wall. The guide fixed pulleys 5 are adjusted so that all the guide fixed pulleys 5 fit on the circular wall of the center tube, and the cleaning brush device 3 is adjusted to fit the position of the center tube wall that needs to be cleaned.

[0025] When the equipment is working: the driving motor 13 drives the rubber-coated power roller 9 to rotate through the synchronous belt on the synchronous pulley 11. The surface of the rubber-coated power roller 9 is polyamine resin, and the friction between the rubber-coated power roller 9 and the central pipe wall is generated by pressure. When the pressure is sufficient, the entire central pipe cleaning machine can be driven up and down. During the movement, the friction may be unstable due to dust on the pipe wall, causing the equipment to shake left and right. At this time, the guide fixed pulley 5 plays a guiding and stabilizing role, allowing the equipment to rise parallel. As the equipment rises and falls, the cleaning brush device 3 also rises and falls on the pipe wall to achieve the cleaning of the central pipe wall.

[0026] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
