Description

Technical Field

[0001] The invention relates to the technical field of dirt cleaning, and in particular to a pipeline cleaning device. Background Art

[0002] As pipes are used for a longer time, deposits and dirt may accumulate on the inner wall of the pipe, causing the performance of the inner wall of the pipe to deteriorate. At this time, cleaning the pipe can remove these deposits and dirt, extend the service life of the pipe, and prevent the pipe from clogging.

[0003] The Chinese patent document with the authorization announcement number CN216095352U discloses a water supply pipe cleaning device, including a pulse generator, a cleaning pipeline and a rotating cleaning mechanism. The pulse generator is used to mix the cleaning water with compressed air to generate a cyclonic gas-water pulse wave. The cleaning pipeline is connected to the pulse generator for deriving the gas-water pulse wave. The rotating cleaning mechanism is connected to the cleaning pipeline through a rotating joint. The rotating cleaning mechanism includes a cleaning cavity, which is connected to the rotating joint through a connecting pipe. A plurality of water spray holes are evenly distributed on the cleaning cavity. A plurality of connecting pipes are evenly distributed circumferentially along the central axis of the cleaning cavity. A cleaning roller is installed on the connecting pipe, and a plurality of brush heads are evenly distributed circumferentially on the outer wall of the cleaning cavity.

[0004] When the air-water pulse wave enters the cleaning cavity through the rotary joint and the connecting pipe, it is sprayed out from multiple water spray holes to flush the inner wall of the water supply pipe; at the same time, under the reaction force generated by the spraying of the air-water pulse wave, the entire rotary cleaning mechanism can rotate, and the inner wall of the water supply pipe can be brushed by the brush head and the cleaning roller, thereby cleaning the inner wall of the water supply pipe.

[0005] The above-mentioned implementation uses air-water pulse waves to flush the water supply pipe. Although the water supply pipe is cleaned, it may cause structural damage to the water supply pipe under the action of air pressure and water pressure. At the same time, the brush head and the cleaning roller rotate under the drive of the air-water pulse wave. Although the dirt on the inner wall of the water supply pipe is forced to be stripped, it also aggravates the wear and scratches of the water supply pipe. Therefore, using air-water pulse waves as power makes the cleaning of the water supply pipe more intense, increasing the structural damage of the water supply pipe. Summary of the invention

[0006] The present invention provides a pipeline cleaning device, aiming to solve the problem in the related art that the cleaning of the water supply pipeline is relatively intense, which aggravates the structural damage.

[0007] The pipeline cleaning device of the present invention includes a cleaner and a driving mechanism. The cleaner can be arranged in a water supply pipeline. The driving mechanism is used to control the axial sliding of the cleaner in the water supply pipeline. The cleaner includes a spiral plate coaxially arranged with the water supply pipeline. The spiral plate is a conical structure with one end gathered in its axial direction. The maximum diameter of the spiral plate is equal to the inner diameter of the water supply pipeline, so that part of the outer edge of the spiral plate can contact the inner wall of the water supply pipeline. When water flows through the spiral plate, the spiral plate is subjected to water pressure and rotates.

[0008] When the spiral plate slides in the water supply pipe, due to its conical structure, it can realize the layered peeling of the scale on the inner wall of the water supply pipe, avoiding the direct hard peeling of thick scale, thereby reducing the wear and damage of the water supply pipe. In addition, high-pressure water flushing is not introduced in this embodiment, which reduces the impact damage and impact damage to the water supply pipe. As a result, the spiral plate cleans the inner wall of the water supply pipe more gently and steadily, thereby reducing the structural damage of the water supply pipe.

[0009] Preferably, the spiral plate is provided with a plurality of scraping members arranged along the spiral direction thereof, wherein the scraping members are adjacent to the outer edge of the spiral plate and extend in the axial direction of the spiral plate.

[0010] When the spiral plate drives the scraper to rotate, the scraper scrapes the dirt in a circumferential direction, that is, cleans the dirt in a circle, thus expanding the cleaning range of the dirt and improving the cleaning effect of the dirt.

[0011] Preferably, the scraper is elastically slidably connected to the spiral plate along the spiral direction of the spiral plate.

[0012] When the scraper contacts the dirt, due to the effect of the elastic connection, the scraper forms a flexible contact with the dirt. In this way, the scraper can slide back a proper amount when scraping the dirt. During the sliding, the elastic force gradually increases the scraping force on the dirt, thereby avoiding the rigid peeling of the dirt, making the scraping method of the dirt softer and reducing the friction damage to the water supply pipe.

[0013] Preferably, the scraping member is an elastic member.

[0014] Preferably, the spiral plate is provided with a protrusion on the sliding path of the scraper, and the protrusion is used to cause the scraper to vibrate when the scraper passes by.

[0015] When the scraper is blocked by dirt and moves back, it will pass through the protrusions, and the friction and squeezing effect of the protrusions on the scraper will cause the scraper to vibrate. This vibration makes it easier for the scraper to clean the dirt, which is beneficial for removing the dirt from the water supply pipe. At the same time, the vibration can also shake off the dirt attached to the scraper itself, assisting the self-cleaning of the scraper.

[0016] Preferably, there are a plurality of protrusions, which are arranged at intervals along the spiral direction of the spiral plate.

[0017] The plurality of protrusions ensure the continuity of the vibration of the scraping member, increase the frequency of the vibration of the scraping member, and make the vibration effect better.

[0018] Preferably, the protrusion is a semicircular structure or a sawtooth structure.

[0019] Preferably, the driving mechanism includes a driver, a winding shaft and a rope, the winding shaft is rotatably assembled in the water supply pipe, the driver is installed on the water supply pipe and is used to drive the winding shaft to rotate; one end of the rope is wound around the winding shaft, and the other end is connected to the spiral plate.

[0020] Preferably, a sleeve is formed at the axis of the spiral plate, and the sleeve is rotatably sleeved on the other end of the rope.

[0021] Preferably, the other end of the rope forms two knots disposed on both sides of the kit, or the other end of the rope is provided with two limit buckles disposed on both sides of the kit, and the knots or the limit buckles are used to limit the position of the kit on the rope.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0023] The present invention sets the spiral plate as a conical structure, so that when the spiral plate slides, it can peel off the scale on the inner wall of the water supply pipe layer by layer, avoiding direct hard peeling of the scale, thereby reducing the wear and damage of the water supply pipe. In addition, in this embodiment, high-pressure water is not introduced to wash the pipe wall, reducing the impact damage and damage to the water supply pipe. As a result, the spiral plate cleans the inner wall of the water supply pipe more gently and steadily, thereby reducing the structural damage of the water supply pipe.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] Combine the following Figures 1 to 6 The pipe cleaning device of the present invention is described.

[0036] like Figures 1 to 3 As shown, the pipeline cleaning device of the present invention includes a cleaner and a driving mechanism.

[0037] The cleaner can be placed in the water supply pipe 100, and the cleaner includes a spiral plate 11. After the spiral plate 11 is placed in the water supply pipe 100, the axis of the spiral plate 11 is coaxial with the axis of the water supply pipe 100, and the spiral plate 11 is a conical structure with one end gathered in the axial direction, that is, the spatial shape of the spiral plate 11 is a cone spiral, and the cone top of the spiral plate 11 faces the end of the water supply pipe 100. The maximum diameter of the spiral plate 11 is equal to the inner diameter of the water supply pipe 100, so that the outer edge of the maximum diameter of the spiral plate 11 can contact the inner wall of the water supply pipe 100, which is convenient for scraping the dirt on the inner wall of the water supply pipe 100.

[0038] Continue to refer Figures 2 to 5The driving mechanism is used to control the axial sliding of the spiral plate 11 in the water supply pipe 100, and the driving mechanism includes a driver 21, a winding shaft 22 and a rope 23. The water supply pipe 100 has a four-way pipe joint 101 at the beginning and the end. The winding shaft 22 is rotatably assembled in the four-way pipe joint 101 at the beginning of the water supply pipe 100. The driver 21 is installed on the four-way pipe joint 101 and is used to drive the winding shaft 22 to rotate. The driver 21 can directly use a driving motor, and the driving motor is connected to the winding shaft 22 through a gear pair to control the rotation of the winding shaft 22. The starting end of the rope 23 is wound on the winding shaft 22, and the tail end is connected to the spiral plate 11. The rope 23 can be a steel wire rope, a nylon rope, etc.

[0039] After the water supply pipe 100 has been used for a period of time, the inner wall is prone to scale formation and sediment. At this time, the water supply is maintained normally, the driver 21 controls the winding shaft 22 to slowly release the rope, and the spiral plate 11 gradually slides toward the end of the water supply pipe 100 under the push of the water flow. The outer edge of the spiral plate 11 scrapes off the scale during the sliding. It is worth noting that when the water flows through the spiral plate 11, the spiral plate 11 is affected by the water pressure, thereby rotating itself, thereby improving the scraping effect on the scale.

[0040] Since the spiral plate 11 is a conical structure, during the sliding, the outer edge of the smaller diameter of the spiral plate 11 first contacts the inner layer of the scale. It can be understood that the inner layer of the scale on the inner wall of the water supply pipe 100 is a layer of scale close to the axis of the water supply pipe 100, and the spiral plate 11 first scrapes off the inner layer of scale. Then by analogy, the outer edge of the middle diameter of the spiral plate 11 contacts the middle layer of the scale and peels off the middle layer of scale. Finally, the outer edge of the largest diameter of the spiral plate 11 peels off the outermost layer of scale. In this way, the spiral plate 11 realizes the layer-by-layer peeling of the scale, avoiding the direct hard peeling of the thicker scale, thereby reducing the wear and damage of the water supply pipe 100. In addition, in this embodiment, high-pressure water is not introduced to flush the pipe wall, which also reduces the impact damage and damage to the water supply pipe 100. In summary, the conical structure of the spiral plate 11 is used to realize the layer-by-layer peeling of the scale, and the cleaning of the inner wall of the water supply pipe 100 is softer and smoother, thereby reducing the structural damage of the water supply pipe 100.

[0041] When the spiral plate 11 rotates, the rope 23 is driven to twist, which makes it easy for the rope 23 to be twisted together.

[0042] To this end, continue to refer to Figures 2 to 4 The spiral plate 11 forms a sleeve 111 at the axis of the spiral plate 11, and the axial direction of the sleeve 111 is consistent with the axial direction of the water supply pipe 100. The sleeve 111 is rotatably sleeved on the tail end of the rope 23. In this way, the spiral plate 11 and the rope 23 are rotatably arranged by using the sleeve 111, which prevents the spiral plate 11 from transmitting the rotation action to the rope 23, and ensures the structural stability of the rope 23.

[0043] The tail end of the rope 23 forms two knots on both sides of the kit 111. The two knots restrict the kit 111 in the middle, preventing the kit 111 from sliding on the rope 23, ensuring the stability of the position of the kit 111, and preventing the kit 111 from falling off the rope 23.

[0044] Alternatively, two limit buckles 231 are fixedly disposed at the tail end of the rope 23 and are disposed on both sides of the set 111. The two limit buckles 231 are used to limit the position of the set 111 on the rope 23, and their function is the same as that of a knot.

[0045] Continue to refer Figure 3 and Figure 4 The spiral plate 11 is provided with a plurality of scraping members 112 arranged along the spiral direction thereof, the distance between two adjacent scraping members 112 is equal, the scraping members 112 are close to the outer edge of the spiral plate 11 and extend in the axial direction of the spiral plate 11 .

[0046] When the spiral plate 11 rotates, it drives the scraper 112 to rotate, and the scraper 112 scrapes the dirt in the circumferential direction, that is, it cleans the dirt in a circle, thus expanding the cleaning range of the dirt and improving the cleaning effect of the dirt. In other words, the scraper 112 is equivalent to the extension of the thickness of the spiral plate 11 in the axial direction, thereby increasing the scraping range of the dirt, and the scraper 112 can be preferably used in the dirt area with thicker layer and larger area.

[0047] When the scraper 112 contacts the dirt, it is in rigid contact with the dirt, so the scraping of the dirt is relatively rigid and direct, which is easy to aggravate the friction damage of the water supply pipe 100.

[0048] To this end, continue to refer to Figure 4 A closed frame 113 is formed on the spiral surface of the spiral plate 11, and a slide groove 1131 is provided in the closed frame 113 along the spiral direction of the spiral plate 11. The scraper 112 is slidably assembled in the slide groove 1131, and the scraper 112 is connected to the closed frame 113 through a return spring 1121.

[0049] Therefore, when the scraper 112 contacts the dirt, due to the setting of the return spring 1121, the scraper 112 forms a flexible contact with the dirt, so that the scraper 112 can slide back a proper amount when scraping the dirt. During the sliding, the scraping force on the dirt is gradually increased through the compression of the return spring 1121, thereby avoiding the rigid peeling of the dirt, making the scraping method of the dirt softer, and reducing the friction damage to the water supply pipe 100.

[0050] Continue to refer Figure 4The closed frame 113 is provided with protrusions 1132 on the sliding path of the scraper 112. There are multiple protrusions 1132 and they are arranged at equal intervals along the spiral direction of the spiral plate 11. When the scraper 112 is blocked by dirt and moves back and slides, it will pass through multiple protrusions 1132 in sequence. The friction and squeezing effect of the protrusions 1132 on the scraper 112 causes the scraper 112 to vibrate. The vibration makes it easier for the scraper 112 to clean the dirt, which is beneficial for removing the dirt from the water supply pipe 100. At the same time, the vibration can also shake off the dirt attached to the scraper 112 itself, assisting the self-cleaning of the scraper 112. The multiple protrusions 1132 ensure the continuous vibration of the scraper 112, increase the frequency of the vibration of the scraper 112, and make the vibration effect better.

[0051] The protrusion 1132 is a semicircular structure or a sawtooth structure, which not only prevents the protrusion from preventing the scraper 112 from moving back normally, but also ensures that the protrusion has appropriate friction and compression on the scraper 112, thereby ensuring the vibration effect of the scraper 112.

[0052] Continue to refer Figure 2 and Figure 6 In this embodiment, a collecting tank 102 is provided in the four-way pipe joint 101 at the end of the water supply pipe 100. Specifically, the interface at the bottom of the four-way pipe joint 101 can be closed by a flange, so that the collecting tank 102 is formed at the interface. A filter screen 103 is also fixedly provided in the four-way pipe joint 101 at the end of the water supply pipe 100. The filter screen 103 is located beside the collecting tank 102 and is closer to the outside relative to the collecting tank 102. When water flows through the filter screen 103, the filter screen 103 filters and isolates the scraped dirt, thereby ensuring the purity of the water used at the terminal. During the water use stop stage, the water in the water supply pipe 100 no longer flows. At this time, the dirt on the filter screen 103 can gradually settle in the collecting tank 102. When it accumulates to a certain amount, the above-mentioned flange can be removed or the existing valve opening and closing technology can be used to discharge the dirt.

[0053] Therefore, in this embodiment, the spiral plate 11 can clean the inner wall of the water supply pipe 100 without stopping the water supply or dismantling the machine, thus ensuring the operation of normal water supply, while also simplifying the operation and eliminating the workload of workers when dismantling the machine.

[0054] In other embodiments, the cone top of the spiral plate 11 can also be facing the starting end of the water supply pipe 100. When the water supply pipe 100 needs to be cleaned, the winding shaft 22 can gradually reel in the rope, and the spiral plate 11 goes against the water flow and gradually moves toward the starting end of the water supply pipe 100. In this way, the spiral plate 11 can also achieve layered scraping of dirt on the inner wall of the water supply pipe 100.

[0055] In other embodiments, the scraper 112 may also be fixed on the spiral plate 11 , and is an elastic member, specifically, an elastic rubber rod, a plastic rod, or a metal strip.

[0056] In other embodiments, the driving mechanism can also use hydraulic telescopic, pneumatic telescopic, or electric telescopic mechanisms to control the movement of the spiral plate 11, or use a rack and pinion mechanism to control the movement of the spiral plate 11, or use a water hose to replace the rope 23, and the tail end of the water hose is connected to an existing "water rat" or "water mouse" that can walk in the pipeline, thereby using the reaction of water pressure to achieve the movement of the spiral plate 11.
