Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a pipeline cleaning device. Background Technology

[0002] Pipeline cleaning is an important maintenance task that involves ensuring the normal operation of the pipeline system and protecting the safety of users. The specific methods and precautions for cleaning vary depending on the pipeline system. Whether it is a deep-sea oil and gas pipeline, a carbon dioxide transmission pipeline, or a pipeline for daily life facilities, it is necessary to strictly abide by the relevant safety operating procedures, adopt appropriate technologies and equipment, ensure the safety of personnel, and ensure the normal operation of the pipeline system.

[0003] There are two main cleaning methods for vertically installed pipes: one is to use pressurized water to flush, and the other is to use a cylindrical cleaning brush for rotary cleaning. If the first method is used, high-pressure water is poured into the pipe from one end and then discharged at high speed from the other end to flush the inner wall. However, as the usage time increases, the adhesion of deposits to the pipe wall also increases. Simply flushing is insufficient to completely remove these deposits, often requiring multiple flushes. This reduces cleaning efficiency, wastes water resources, and is quite inconvenient.

[0004] If the second cleaning method is used, pipes with different functions, even those with the same function or those used in the same scenario, will have different diameters. When cleaning is needed, it's necessary to frequently change cleaning brushes of different sizes according to the pipe diameter to ensure the cleaning tool isn't too large to fit into the pipe, or too small, unable to utilize the pipe wall for support and causing it to wobble inside due to rotational force, resulting in insufficient cleaning. This leads to poorer cleaning results, a more cumbersome process, and reduced efficiency.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0025] like Figures 1 to 9 As shown in the figure, this application provides a pipeline cleaning device, including a main body 101, a cleaning component 2, and a traveling mechanism 3. A motor 105 and a traction connection are mounted on the main body 101. The cleaning component 2 is drivenly connected to the motor 105, and the cleaning component 2 and the traction connection are located at both ends of the main body 101. The traveling mechanism 3 is mounted on the main body 101 and has multiple rollers 304. Each roller 304 is arranged at intervals around the circumference of the main body 101, and all rollers 304 are located within the same trajectory circle. The traveling mechanism can adjust the distance between each roller 304 and the main body 101 to adjust the diameter of the trajectory circle.

[0026] The pipe cleaning device provided in this application, by setting up a cleaning component 2, which is driven by a motor 105 to rub against the dirt on the inner wall of the pipe, makes the dirt easy to fall off, thereby improving the cleaning effect and efficiency, and also effectively reducing the waste of water resources.

[0027] The pipe cleaning device provided in this application, by setting an adjustable roller 304 spacing travel mechanism 3, can be adapted to various pipes of different sizes. When cleaning pipes of different diameters, there is no need to frequently change the brush head. Moreover, in pipes of different diameters, the roller 304 spacing can be adjusted so that multiple rollers 304 can be supported on the inner wall of the pipe. This ensures that the cleaning component 2 is stable in position under the support of the travel mechanism 3 during the movement, ensuring that the cleaning component 2 can stably clean the area to be cleaned on the inner wall of the pipe, ensuring the cleaning effect, simplifying the cleaning process, further improving cleaning efficiency, and further reducing water waste.

[0028] In some possible implementations, the traveling mechanism 3 includes multiple traveling frames, each of which is sequentially arranged around the circumference of the equipment body 101. Each traveling frame includes a hinge seat 301, a pitch link 303, and a support link 306. The hinge seat 301 is fixed to the equipment body 101. One end of the pitch link 303 is hinged to the hinge seat 301, and the other end of the pitch link 303 is provided with a roller 304. One end of the support link 306 is hinged to the pitch link 303, and the other end of the support link 306 can move along the length of the equipment body 101 and be fixed to adjust the pitch angle of the pitch link 303. Each roller 304 is paired with a pitch linkage 303, enabling more precise adjustment. The individual adjustment of each roller 304 allows the device to accommodate not only circular pipes but also square, elliptical, trapezoidal, or other irregularly shaped pipes, ensuring stable support in all applications. Furthermore, the use of the pitch linkage 303 to connect and adjust the position of the rollers 304 provides a wide adjustment range and excellent support stability.

[0029] In some possible implementations, the traveling frame includes a fixed block 309, a translation block 307, and an adjusting screw 308. The fixed block 309 is fixed to the equipment body 101, and the adjusting screw 308 is rotatably connected to the fixed block 309, with the adjusting screw 308 parallel to the equipment body 101. The translation block 307 is threaded onto the adjusting screw 308, and one end of the support connecting rod 306 is hinged to the translation block 307. Rotating the adjusting screw 308 can drive the translation block 307 to translate along the adjusting screw 308.

[0030] Rotating the adjusting screw 308 in the first direction causes the translation block 307 to move away from the fixed block 309, driven by the thread. This moves the support link 306 and the end of the pitch link 303 connected to the roller 304 closer to the equipment body, thus reducing the adjustable pipe diameter. Rotating the adjusting screw 308 in the second direction, opposite to the first direction, causes the translation block 307 to move closer to the fixed block 309, driven by the thread. This moves the support link 306 and the end of the pitch link 303 connected to the roller 304 further away from the equipment body, thus increasing the adjustable pipe diameter.

[0031] A bearing 204 may be provided between the adjusting screw 308 and the fixed block 309. The adjusting screw 308 can rotate relative to the fixed block 309, but it cannot slide along the length of the adjusting screw 308.

[0032] In some possible implementations, the pipe cleaning device includes a traction cable 104, and the traction connection includes a traction engagement ring 102, with one end of the traction cable 104 connected to the traction engagement ring 102. An external device such as a winch is used to secure one end of the sufficiently long traction cable 104. The device is then inserted into the pipe body from the top of the vertically installed pipe, and the traction cable 104 is used to lower the entire device inside the pipe body to the pipe opening at the other end. Using the external traction equipment such as a winch, the traction cable 104 is pulled, moving the entire device along the inner wall of the pipe to the top of the pipe, completing the overall cleaning of the inner wall of the pipe.

[0033] In some possible implementations, a spacer 11 is provided on the inner wall of the traction engagement ring 102, and a traction ring 103 is provided at one end of the traction cable 104, the traction ring 103 being sleeved on the traction engagement ring 102. The spacer 11 is made of flexible material, which can effectively reduce the degree of wear generated during traction.

[0034] Furthermore, a stabilizing frame 12 is fixedly connected to the side of the traction arm that connects to the equipment body. The stabilizing frames 12 are all triangular structures, which can effectively ensure the stability of the traction arm during the traction process. In some possible implementations, the cleaning assembly 2 includes a bracket and a plurality of friction elements 205. The bracket is connected to the shaft of the motor 105, and each of the friction elements 205 is disposed on the peripheral edge of the bracket, and the friction elements 205 are arranged at intervals around the circumference of the bracket. The bracket positions the outer edge of the friction element 205 so that the outer side of the friction element 205 contacts the inner wall of the tube body.

[0035] In some possible implementations, the bracket includes a plug head 201, multiple extension arms, and multiple expansion members 203. The plug head 201 is connected to the shaft of the motor 105. Each extension arm is spaced apart circumferentially around the plug head 201 and connected to it. Each expansion member 203 is threadedly connected to a corresponding extension arm, and each friction member 205 is connected to a corresponding expansion member 203. Rotating the expansion member 203 allows it to move along the length of the extension arm. By rotating the expansion member 203, the distance between the friction member 205 and the device body 101 is adjusted, thereby adjusting the radius of the rotated friction member 205. This allows for adjustment to accommodate pipes of different diameters, ensuring effective cleaning.

[0036] In some possible implementations, the extension member 203 may be an extension screw, with a bearing 204 fixedly connected to the top of each extension screw, and the outer side of the bearing 204 fixedly connected to the cleaning plate.

[0037] In some possible implementations, the bracket includes a handle 7, a spring 8, and a sleeve 6. The sleeve 6 is fixedly fitted onto the extension member 203, and the handle 7 passes through the sleeve 6 and is vertically connected to the extension member 203. The spring 8 is fitted onto the extension member 203, with its two ends abutting against the extension arm and the sleeve 6, respectively. The handle 7 facilitates gripping and applying force, making rotation of the extension member 203 less strenuous. The spring 8 helps the friction member 205 return to its original position after rotation, ensuring effective cleaning.

[0038] Furthermore, each adjacent extension arm 202 is fixedly connected with a reinforcing frame 5.

[0039] In some possible implementations, the pipeline cleaning device includes a limiting mechanism 4. The limiting mechanism 4 is vertically connected to the device body 101, with both ends extending out of the device body 101. Support wheels 404 are provided at both ends of the limiting mechanism 4. The limiting mechanism 4 assists the traveling mechanism 3 in positioning within the pipeline, ensuring more stable rotation of the cleaning component 2 and better cleaning results.

[0040] In some possible implementations, the limiting mechanism 4 includes a rail beam 401, two sliding rails 402, and two locking assemblies. The rail beam 401 is vertically connected to the device body 101, with both ends extending out of the device body 101. The two sliding rails 402 are respectively disposed at both ends of the rail beam 401 and are slidably connected to the two rail beams 401. Each end of the two sliding rails 402 is provided with a support wheel 404. Both locking assemblies are disposed on the rail beam 401 and are used to lock or release the corresponding sliding rail 402.

[0041] In some possible implementations, several sliding rails 402 are symmetrically arranged. The locking assembly includes a connecting frame 403 fixedly connected between the sliding rail 402 and the support wheel 404, and the support wheel 404 is rotatably connected to the inner side of the connecting frame 403. The locking assembly includes a slider 405 and a locking screw 406. The slider 405 is slidably connected to the inner side of the sliding rail 402, and the locking screw 406 is threadedly connected to the inner side of the slider 405. A pressure ring 407 is fixedly connected to the end of the locking screw 406 away from the slider 405, and a knob 13 is fixedly connected to the outer side of the pressure ring 407.

[0042] In some possible implementations, the motor 105 is fixedly connected to the inner side of the device body 101. An opening is provided on one side of the device body 101, and a plurality of first adapter pieces 106 are provided on the outer periphery of the opening, with the plurality of first adapter pieces 106 arranged symmetrically. A cover plate 109 is also provided, which can close or open the opening. A second adapter piece 108 is provided on the outer periphery of the cover plate 109, and a first screw 107 passes through the second adapter piece 108 and is connected to the first adapter piece.

[0043] In some possible implementations, a gasket 10 is movably provided between the first screw 107 and the first adapter plate 106, and a second adapter plate 108 is threadedly connected to the outer side of the other end of the first screw 107. A cover plate 109 is fixedly connected to the bottom of the second adapter plate 108, which can effectively ensure the stability of the gasket 10 during long-term use.

[0044] In some possible implementations, a sealing gasket 99 is fixedly connected to the side of the cover plate 109 near the main body 101 of the equipment. The sealing gasket 99 is made of a flexible material, which can effectively ensure the sealing performance and reduce the risk of moisture infiltration.
