Description

Technical Field

[0001] This invention belongs to the field of pipeline cleaning, and specifically relates to a directional pipe cleaning device. Background Technology

[0002] Currently, cleaning devices used for directional tubes typically consist of a front cleaning brush head, a middle drive mechanism, and a rear control assembly. The cleaning brush head can only clean the inner wall of the tube. The inventors have discovered that current cleaning devices cannot remove gunpowder residue, dust, and oil contaminants remaining in the spiral grooves of directional tubes, potentially affecting future use. Therefore, there is an urgent need to invent a directional tube cleaning device that can achieve comprehensive and thorough cleaning of directional tubes. Summary of the Invention

[0005] The connecting frame includes a shaft, left and right sealing plates movably connected to the shaft, and upper and lower sealing plates connected to the left and right sealing plates.

[0006] The drive motor is located inside the connecting frame, and the output shaft of the drive motor extends out of the upper and lower sealing plates and is connected to the groove brush for transmission.

[0007] The grooved brush is connected to the output shaft of a drive motor via a connecting sleeve; a bearing is fitted on the outer side of the connecting sleeve; a support plate is connected to the outer ring of the bearing; a guide wheel is connected to the support plate via a guide wheel connecting shaft; a positioning rod is provided between the support plate and the connecting frame.

[0008] The support plate includes a circular plate connected to an outer ring of the bearing and two horizontal plates connected to both sides of the circular plate for mounting the guide wheel connecting shaft.

[0009] The left and right sealing plates are movably connected to the shaft via two bearings; the shaft is provided with two positioning sleeves for limiting the left and right sealing plates.

[0010] The outer diameter of the guide wheel is adapted to the width of the groove.

[0011] There are two groove brush assemblies, which are respectively located at both ends of the connecting frame.

[0012] The second connecting frame includes a front plate for assembling the second drive motor, a middle plate that cooperates with the front plate to fix the mop head, and a connecting plate that connects the middle plate and the shaft; the connecting plate is connected to the middle plate via multiple connecting cylinders.

[0013] The intermediate plate is fixedly connected to the front plate via multiple connecting shafts.

[0014] The output ends of the drive motor extend out of the front plate and are connected to the top cover used for assembling the wire brush disc.

[0015] It also includes a connection assembly for connecting to a drive mechanism; the connection assembly includes a rear plate mounted on the shaft and a connector disposed on the rear plate.

[0016] This invention, through its disc brush mechanism and grooved brush mechanism, can clean not only the inner wall of the pipe but also residues within the spiral grooves. The brush head of this invention replaces the brush head of the original directional pipe cleaning device. A mid-section drive mechanism moves the brush head inside the pipe, and the operation is controlled by a tail control component. A motor drives the wire brush disc and grooved brush to rotate, cleaning the inner wall of the pipe and the spiral grooves. The front wire brush disc can also be removed, and protective oil can be applied to the mop head to protect the inner wall of the pipe. This invention has advantages such as simple operation, high cleaning efficiency, and a high first-pass yield rate. Attached Figure Description

Each groove brush assembly includes a guide wheel 3 adapted to the grooves, a pen-shaped groove brush 4, and a drive motor 5 for rotating the groove brush 4. The disc brush mechanism includes a wire brush disc 1 connected to the connecting frame 1 via a connecting frame 2, a drive motor 7 for rotating the wire brush disc 1, and a mop head 2 for pushing dirt from the inner wall of the pipe forward to the pipe opening. The wire brush disc 1 and the mop head 2 are purchased components. The drive motor 7 rotates the wire brush disc 1 to clean the pipe wall, and the mop head at the rear pushes the dirt forward to the pipe opening. The groove brush 4, driven by the drive motor 5, can rotate within the spiral grooves to clean them.

[0028] The connecting frame includes a shaft 12, left and right sealing plates 10 movably connected to the shaft 12, upper and lower sealing plates 11 connected to the left and right sealing plates, and front and rear sealing plates 21. Guide wheels 3 are mounted on a guide wheel connecting shaft 16, the other end of which is screwed onto a support plate 15. The support plate 15 is formed by stacking two plates, with a bearing 13 installed between them. A connecting sleeve 14 is installed in the middle of the bearing 14, with one end connected to a drive motor 5 and the other end connected to a grooved brush 4. A positioning rod 19 is mounted on the support plate 15, and nuts 20 are used to press it tightly onto the left and right sealing plates 10 to prevent the support plate 15 from rotating freely around the bearing 13. Two positioning sleeves 22 for the grooved brush assembly are provided on the shaft 12 to prevent the left and right sealing plates from moving back and forth on the shaft 12. The drive motor 5 is bolted to the upper and lower sealing plates 11. The grooved brush 4 is connected to the head of the drive motor 5, and the guide wheels 3 are installed on both sides of the grooved brush. The groove brush assembly is connected and fixed to the upper and lower sealing plates 11 by a drive motor 5. The sealing plates are connected by bolts. Bearings 18 are installed in the inner holes of the left and right sealing plates 10. The groove brush assembly can rotate freely through the bearings 18 to achieve the purpose of cleaning the spiral grooves.

[0029] The connecting frame 215 includes a front plate 23 for mounting the drive motor 22, an intermediate plate 26 that cooperates with the front plate 23 to fix the mop head 2, and a connecting plate 8 connecting the intermediate plate 26 and the shaft 12. The connecting plate 8 is connected to the intermediate plate 26 via multiple connecting cylinders 29. The intermediate plate 26 and the front plate 23 are fixedly connected via multiple connecting shafts 27 and tightened with nuts 28. The drive motor 22 is bolted to the front plate 23, and the top cover 9 is directly screwed onto the piston rod end of the drive motor 22; the rotation of the motor directly drives the top cover to rotate. The wire brush disc is bolted to the top cover, and the mop head 2 is bolted and nut-tightened to the front plate.

[0030] The rear end of shaft 12 is provided with a rear plate 25, on which a drive mechanism connector 6 and an electrical connector plug are provided. The electrical connector plug is an outsourced component that enables electrical connection, while the connector enables mechanical connection. The connector 6 can be a lock head from a connecting device as described in Chinese patent CN216478315U.

[0031] In use, the entire cleaning device is placed inside the pipe. The groove brush is guided into the spiral groove by the guide wheel 3. The control component at the tail controls the extension wheel on the drive mechanism 0 to tighten, so that the rubber wheel is close to the pipe wall. Then, the drive motor 2 and drive motor 1 are energized, which drives the front wire brush disc and the groove brush to rotate, cleaning the inner wall of the pipe and the spiral groove. The cleaned dirt is carried to the pipe opening by the mop head. When the cleaning device reaches the pipe opening, it touches the proximity switch, and the cleaning device stops automatically. The tail control component can control the reverse movement so that the cleaning device returns to clean again.

[0032] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
