Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning, and in particular to a pipeline cleaning device. Background Technology

[0002] In large and medium-sized irrigation projects, pipeline cleaning devices are core equipment for ensuring the smooth operation of water conveyance systems. These devices come in various types, encompassing mechanical, chemical, and intelligent cleaning methods. Mechanical cleaning equipment, such as pigs and high-pressure water jet devices, removes deposits through physical means; chemical cleaning uses acid and alkali agents to dissolve scale; and intelligent cleaning technologies, such as ultrasonic descaling systems and intelligent pigs with integrated sensors, enable precise monitoring and efficient cleaning. However, these devices face problems in practical operation, including low cleaning efficiency, poor equipment reliability, and environmental hazards, mainly due to the complex characteristics of deposits, limitations in pipeline design, and insufficient technological adaptation. By innovatively applying intelligent pigs, optimizing pipeline design, improving material structure, and strengthening environmental management, the performance of cleaning devices can be significantly improved, ensuring the long-term stable operation of irrigation pipelines.

[0003] In the prior art, a pipeline cleaning device is disclosed in Chinese utility model with announcement number CN222519437U. It uses the state of the drill bit to clean the inner wall of the pipeline. However, because its contact surface is too large, although the operating coverage is large, the actual adjustment method is limited to a very small range, which cannot flexibly handle different pipeline conditions. In the field of large and medium-sized irrigation area projects, the sediments in the irrigation pipelines are of various types and may change in composition due to seasonal irrigation, which makes it difficult for traditional methods to adapt. Utility Model Content

[0004] The purpose of this invention is to provide a pipe cleaning device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pipe cleaning device includes a traveling mechanism for driving the device to travel inside the pipe, a cleaning mechanism for cleaning the inner wall of the pipe, and a deep cleaning mechanism for handling clumps and difficult-to-clean stains. The deep cleaning mechanism is installed on the outer surface of the cleaning mechanism. The cleaning mechanism is composed of several independent structures, and several cleaning mechanisms are arranged in a circumferential array outside the torsion mechanism. The inner side of the cleaning mechanism is connected to the torsion mechanism through an adjustment mechanism. The torsion mechanism is installed at the power output end of the traveling mechanism.

[0007] The torsion mechanism includes a fixed disk and a torsion disk. The fixed disk is connected to the traveling mechanism via a coupling shaft. The torsion disk is rotatably connected to the side of the fixed disk corresponding to the traveling mechanism. The torsion disk is rotatably connected to the fixed disk. Torsion springs that provide reset power are provided on the end faces of the fixed disk and the torsion disk.

[0008] The cleaning mechanism includes a fixed block, a cleaning block is provided on the outside of the fixed block, and a fixed shaft and a swing shaft are respectively provided on the inside of the fixed block corresponding to the fixed plate and the torsion plate;

[0009] The deep cleaning mechanism includes a scraper and a fixed plate. The fixed plate is slidably connected inside the fixed block. Several scrapers are provided on the top of the fixed plate. The top of the scraper passes through the cleaning block and extends out of the cleaning block. The bottom of the scraper cooperates with the lifting component on the fixed shaft and the squeezing component on the swing shaft.

[0010] Preferably: one end of the fixed shaft is fixed to the fixed disk, one end of the swing shaft is fixed to the torsion disk, a lifting sleeve of the lifting component is provided at the top of the fixed shaft corresponding to the scraper position, the lifting sleeve is fixed to the scraper, an extrusion block is provided on the fixed shaft, an extrusion groove that matches the extrusion block is formed on the inner wall of the lifting sleeve, and a matching ball head of the extrusion component is formed at the top of the swing shaft, the top of the matching ball head is flat.

[0011] Preferably, the relative rotation angle between the torsion disc and the fixed disc is 0°-10°.

[0012] Preferably, the scraper has a V-shaped joint, and when the fixed block is in its initial state, the angle between the fixed shaft and the axis of the fixed disk is 45°.

[0013] Preferably, the scraper is a thin sheet of steel.

[0014] Preferably, the mating ball head is rotatably connected to the fixed block.

[0015] Preferably, the bottom surface of the fixing plate is pressed together with the top surface of the mating ball head.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. When stubborn stains such as clumps appear on the inner wall of the pipe, the rotational misalignment between the fixed plate and the torsion plate causes the scraper to protrude. The top corner of the scraper impacts the stains, thereby quickly and effectively removing them. Combined with the friction of the cleaning block, this ensures thorough cleaning of the inside of the pipe.

[0018] 2. Under normal cleaning conditions, the scraper does not protrude significantly. By utilizing the cooperation between the scraper and the cleaning block, as well as the elastic power provided by the torsion spring, the scraper is made to rub against the inner wall at multiple angles, thereby improving the cleaning effect under normal conditions.

[0035] The present invention will be further described below with reference to the accompanying drawings:

[0036] like Figures 1-11As shown, a pipe cleaning device includes a traveling mechanism 1 for driving the device to travel inside the pipe, a cleaning mechanism 3 for cleaning the inner wall of the pipe, and a deep cleaning mechanism 5 for handling clumps and difficult-to-clean stains. The deep cleaning mechanism 5 is installed on the outer side of the cleaning mechanism 3. The cleaning mechanism 3 is composed of several independent structures, and several cleaning mechanisms 3 are arranged in a circumferential array outside the torsion mechanism 2. The inner side of the cleaning mechanism 3 is connected to the torsion mechanism 2 through an adjustment mechanism 4. The torsion mechanism 2 is installed at the power output end of the traveling mechanism 1.

[0037] The torsion mechanism 2 includes a fixed disk 21 and a torsion disk 22. The fixed disk 21 is connected to the traveling mechanism 1 via a coupling shaft. The torsion disk 22 is rotatably connected to the side of the fixed disk 21 corresponding to the traveling mechanism 1. The torsion disk 22 is rotatably connected to the fixed disk 21. Torsion springs 23 that provide reset power are provided on the corresponding end faces of the fixed disk 21 and the torsion disk 22.

[0038] The cleaning mechanism 3 includes a fixed block 31, a cleaning block 32 is provided on the outside of the fixed block 31, and a fixed shaft 41 and a swing shaft 42 are respectively provided on the inside of the fixed block 31 corresponding to the fixed plate 21 and the torsion plate 22.

[0039] The deep cleaning mechanism 5 includes a scraper 51 and a fixed plate 52. The fixed plate 52 is slidably connected inside the fixed block 31. Several scrapers 51 are provided on the top of the fixed plate 52. The top of the scraper 51 passes through the cleaning block 32 and extends out of the cleaning block 32. The bottom of the scraper 51 cooperates with the lifting component on the fixed shaft 41 and the squeezing component on the swing shaft 42.

[0040] Preferably, one end of the fixed shaft 41 is fixedly connected to the fixed disk 21, one end of the swing shaft 42 is fixedly connected to the torsion disk 22, the top of the fixed shaft 41 is provided with a lifting sleeve 411 corresponding to the scraper 51, the lifting sleeve 411 is fixedly connected to the scraper 51, the fixed shaft 41 is provided with an extrusion block 412, the inner wall of the lifting sleeve 411 is formed with an extrusion groove 413 that matches the extrusion block 412, the top of the swing shaft 42 is formed with a matching ball head 421 of the extrusion component, and the top of the matching ball head 421 is a flat surface.

[0041] Preferably, the relative rotation angle between the torsion disc 22 and the fixed disc 21 is 0°-10° to avoid excessive rotation, which would prevent effective cleaning.

[0042] Preferably, the scraper 51 has a V-shaped joint, and when the scraper 51 is in the initial state of the fixed block 31, the angle between the axis of the fixed shaft 41 and the axis of the fixed disk 21 is 45°, which improves the impact effect by utilizing the tip position of the V-shape.

[0043] Preferably, the scraper 51 is a thin sheet of steel with toughness, so that the two sides of the V-shape can break up the scale.

[0044] Preferred: The ball head 421 is rotated and connected to the fixing block 31.

[0045] Preferably, the bottom surface of the fixing plate 52 is pressed together with the top surface of the mating ball head 421.

[0046] Working principle: The traveling mechanism 1 and the motor inside the traveling mechanism 1 start to drive the fixed plate 21 to rotate, thereby driving the fixed block 31 and the cleaning block 32 outside the fixed plate 21 to rotate, and perform friction cleaning on the inner wall of the pipe. At this time, because the friction between the cleaning block 32 and the inner wall of the pipe is not large, the reverse friction force of the pipe on the cleaning block 32 is insufficient to overcome the torque of the torsion spring 23 between the fixed plate 21 and the torsion plate 22 during the friction process.

[0047] When the inner wall of the pipe becomes caked due to mud, scale, etc., the resistance of the cleaning block 32 will increase when the equipment runs to the corresponding area. As the force acting on the cleaning block 32 increases, the torque of the torsion spring 23 is overcome. At this time, the torsion disc 22 stops relative to the fixed disc 21, and a torsional misalignment occurs between the fixed disc 21 and the torsion disc 22. This torsional misalignment then causes a misalignment between the fixed shaft 41 and the swing shaft 42, causing the cleaning block 32 to twist accordingly (e.g., Figures 9 to 10 When the pressure changes, a squeezing and twisting occurs between the squeezing groove 413 and the squeezing block 412 at the bottom of the cleaning block 32. The relative position of the lifting sleeve 411 increases. After the lifting sleeve 411 increases in height, the fixed shaft 41 and the fixed block 31 remain fixed. The fixed plate 52 is lifted by the supporting force of the lifting sleeve 411. Consequently, the scraper 51 also extends out of the top surface of the cleaning block 32. Since the top of the mating ball head 421 is flat, after twisting, the side will also squeeze the scraper 51, causing the other side of the scraper 51 to also be lifted. When the scraper 51 extends out of the cleaning block 32, the top of the scraper 51 impacts the slab. The scraper 51 has a V-shaped structure, and the pressure is greatest at the apex of the scraper 51, which impacts and scrapes away the slab, thus treating the slab. After the slab is treated, the resistance decreases, and the torsion spring 23 resets the fixed plate 21 and the torsion plate 22. The scraper 51 retracts and continues to be treated by friction using the cleaning block 32.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
