Description

Technical Field

[0001] This invention belongs to the field of pipeline internal cleaning technology, specifically referring to a circulating water-saving pipeline installation and cleaning machine. Background Technology

[0002] Internal cleaning of long pipelines typically involves inserting a cleaning machine into the pipeline, allowing it to travel within and clean the inner walls. In conventional methods, the end of the cleaning machine needs to be connected to a water pipe leading to the outside to ensure a water supply. However, this method suffers from high water consumption and significant water waste, as detailed below: A: Water resources are generally used only once, but the total consumption is large; B: Due to the large amount of water accumulated inside the pipes, an additional water removal process is required after cleaning. C: To supply water to the equipment through the water supply pipe, the water supply pipe needs to be filled first, which is a waste of water. The longer the pipe, the more serious the waste of water in the water supply pipe. Summary of the Invention

[0003] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a circulating water-saving pipe installation and cleaning machine. This solution replaces the water supply pipe by carrying a water bag, so that water waste no longer increases with the increase of pipe length; through circulating filtration, water resources can be reused, which can greatly reduce water consumption compared with conventional solutions. Furthermore, in order to maintain the technical effect of automatic water supply from the hollow shaft, this invention also proposes a water jacket and a water collecting auger with a variable diameter structure. Through the variable diameter design of the water jacket and the water collecting auger, the technical effect of supplying water towards the water inlet window can still be maintained even when the water storage capacity inside the water jacket decreases.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a circulating water-saving pipe installation cleaning machine, including a water collection and pressurization component, a dual circulation filtration mechanism, a cleaning drive component, a water spray component, and a traveling support component. The dual circulation filtration mechanism is disposed on the water collection and pressurization component, the cleaning drive component is disposed at the end of the water collection and pressurization component, the water spray component is disposed on the cleaning drive component, and the traveling support component is disposed on the water collection and pressurization component and the dual circulation filtration mechanism. The water collection and pressurization assembly includes a water tank, a hollow shaft, and a water collection auger. The hollow shaft is rotatably disposed in the water tank, and the water collection auger is fixedly connected to the hollow shaft. One end of the hollow shaft is provided with a water inlet window. The diameter of the water tank gradually decreases at the end near the water inlet window, and the cross-sectional profiles of the water collection auger and the water tank correspond to each other.

[0005] When the hollow shaft rotates with the water collecting auger, it can squeeze the water in the water tank, causing it to enter the interior of the hollow shaft through the water inlet window and be delivered towards the water spray assembly. Through the variable diameter design of the water tank and the water collecting auger, the technical effect of supplying water towards the water inlet window can still be maintained even when the water storage capacity inside the water tank decreases.

[0006] Furthermore, the dual circulation filtration mechanism includes a reflux collection component, a dual filtration component, and a one-way valve plate. The reflux collection component is mounted on a hollow shaft, the dual filtration component is mounted on the side of the water tank, and a water inlet is provided on one side of the water tank. The one-way valve plate is located at the water inlet and has an elastic part that covers the inside of the water inlet.

[0007] The one-way valve plate allows liquid to enter the water tank through the inlet hole by the deformation of the elastic part, but it cannot allow the liquid in the water tank to exit from the inlet hole.

[0008] Preferably, the reflux collection assembly includes a centrifuge chamber, a sandwich-type reflux hood, and a filter hood. The centrifuge chamber is fixed to a hollow shaft, and centrifuge plates are arranged in an array inside the centrifuge chamber. The sandwich-type reflux hood is fixed to the hollow shaft, and the end of the sandwich-type reflux hood abuts against the inner wall of the pipe and is made of flexible material. The interior of the sandwich-type reflux hood is divided into several independent areas by inclined partitions. The filter hood is disposed on a dual-filter assembly.

[0009] When the centrifuge plate rotates, the liquid inside the centrifuge chamber rotates with it, causing the liquid to move towards the filter hood under the action of centrifugal force, thereby achieving the filtration of particulate residue.

[0010] The interior of the sandwich-type reflux hood is divided into several independent areas by partitions. On the one hand, it can form a straw-like structure, allowing the independent area at the bottom to independently draw liquid under negative pressure. On the other hand, when the independent area rotates from the bottom to the top, it can also transfer the liquid at the bottom of the pipe to the top, and then let it enter the centrifuge chamber under the action of gravity.

[0011] As a further preferred embodiment of the present invention, the dual filtration assembly includes a filter cake chamber, an outer fixing cover, and an adsorbent material. The filter cake chamber is fixed to the water tank, the filter cover is fixed to the filter cake chamber, the outer fixing cover is fixed to the water tank, and the adsorbent material is disposed in the outer fixing cover. Particulate residue enters the filter cake chamber after being filtered by the filter cover, while powdered sludge is adsorbed in the adsorbent material.

[0012] The filter chamber and adsorption material can collect dirt of two different particle sizes, residue and powder, to filter the water and then recycle it in the water tank. This reuse method can greatly reduce the amount of water used in the cleaning process compared with conventional rinsing methods.

[0013] Furthermore, the cleaning drive assembly includes a drive motor, a cleaning wheel, and a wire brush. The drive motor is mounted on the water tank, the output shaft of the drive motor is located at one end of the hollow shaft, the cleaning wheel is located outside the other end of the hollow shaft, and the wire brush is mounted on the cleaning wheel.

[0014] Furthermore, the water spray assembly includes a diverter head, a hose, and a nozzle. The diverter head is located at the other end of the hollow shaft and communicates with the hollow shaft. The nozzle is fixed to the cleaning wheel by a bracket, and the hose is located between the diverter head and the nozzle.

[0015] Furthermore, the traveling support assembly includes a roller support, a swing arm, a preload spring, and a traveling wheel. The swing arm is hinged to the roller support, the preload spring is located between the roller support and the swing arm, and the traveling wheel is located at the end of the swing arm.

[0016] Preferably, the travel support assembly further includes a mounting ring disposed on the water tank, one set of the roller supports is disposed outside the outer fixing cover, and the other set of the roller supports is disposed outside the mounting ring.

[0017] As a further preferred embodiment of the present invention, the elastic modulus of the lower preload spring is greater than that of the upper preload spring.

[0018] With the support of the travel support components, the hollow shaft is always located near the central axis of the pipe.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Although this solution cannot recover all the water, it can greatly reduce the amount of water consumed compared with conventional solutions. According to the inner diameter and length of the pipe, enough water is poured into the water bag in advance, so that the internal cleaning of long pipes can be achieved without connecting to external water sources.

[0020] (2) When the hollow shaft rotates with the water collecting auger, it can squeeze the water in the water tank, so that it enters the interior of the hollow shaft through the water inlet window and is transported toward the water spray assembly; through the variable diameter design of the water tank and the water collecting auger, the technical effect of supplying water toward the water inlet window can still be maintained when the water storage in the water tank decreases.

[0021] (3) The one-way valve plate can allow liquid to enter the water tank through the inlet hole by the deformation of the elastic part, but cannot allow the liquid in the water tank to be discharged from the inlet hole.

[0022] (4) When the centrifuge plate rotates, the liquid inside the centrifuge chamber will rotate with it, so that the liquid moves toward the filter cover under the action of centrifugal force, thereby achieving the filtration of particulate residue.

[0023] (5) The interior of the sandwich reflux hood is divided into several independent areas by partitions. On the one hand, it can form a straw-like structure, so that the independent area located below can independently extract liquid under negative pressure. On the other hand, when the independent area rotates from the bottom to the top, it can also transfer the liquid located below the pipe to the top, and then let it enter the centrifuge chamber under the action of gravity.

[0024] (6) The filter chamber and adsorption material can collect dirt of two different particle sizes, residue and powder, respectively, to filter water and then recycle it into the water bag. This reuse method can greatly reduce the amount of water used in the cleaning process compared with conventional rinsing methods. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] like Figures 1-8 As shown, the present invention proposes a circulating water-saving pipe installation cleaning machine, including a water collection and pressurization component 1, a dual circulation filtration mechanism 2, a cleaning drive component 3, a water spray component 4, and a travel support component 5. The dual circulation filtration mechanism 2 is disposed on the water collection and pressurization component 1, the cleaning drive component 3 is disposed at the end of the water collection and pressurization component 1, the water spray component 4 is disposed on the cleaning drive component 3, and the travel support component 5 is disposed on the water collection and pressurization component 1 and the dual circulation filtration mechanism 2. The water collection and pressurization assembly 1 includes a water tank 11, a hollow shaft 12, and a water collection auger 13. The hollow shaft 12 is rotatably disposed in the water tank 11, and the water collection auger 13 is fixedly connected to the hollow shaft 12. One end of the hollow shaft 12 is provided with a water inlet window 121. The diameter of the end of the water tank 11 near the water inlet window 121 gradually decreases, and the cross-sectional profiles of the water collection auger 13 and the water tank 11 correspond to each other.

[0031] When the hollow shaft 12 rotates with the water collecting auger 13, it can squeeze the water in the water tank 11, causing it to enter the interior of the hollow shaft 12 through the water inlet window 121 and be transported toward the water spray assembly 4. Through the variable diameter design of the water tank 11 and the water collecting auger 13, the technical effect of supplying water toward the water inlet window 121 can still be maintained even when the water storage in the water tank 11 decreases.

[0032] The dual circulation filtration mechanism 2 includes a reflux collection component 21, a dual filtration component 22, and a one-way valve plate 23. The reflux collection component 21 is mounted on the hollow shaft 12, and the dual filtration component 22 is mounted on the side of the water tank 11. The water tank 11 has an inlet hole 111 on one side. The one-way valve plate 23 is located at the inlet hole 111 and has an elastic part 231 that covers the inside of the inlet hole 111.

[0033] The one-way valve plate 23 can allow liquid to enter the water tank 11 through the water inlet 111 by the deformation of the elastic part 231, but cannot allow the liquid in the water tank 11 to be discharged from the water inlet 111.

[0034] The reflux collection assembly 21 includes a centrifuge chamber 211, a sandwich-type reflux hood 212, and a filter hood 213. The centrifuge chamber 211 is fixed to the hollow shaft 12. Centrifuge plates 2111 are arranged in an array inside the centrifuge chamber 211. The sandwich-type reflux hood 212 is fixed to the hollow shaft 12. The end of the sandwich-type reflux hood 212 abuts against the inner wall of the pipe and is made of flexible material. The interior of the sandwich-type reflux hood 212 is divided into several independent areas by inclined partitions. The filter hood 213 is disposed on the dual filter assembly 22.

[0035] When the centrifuge plate 2111 rotates, the liquid inside the centrifuge chamber 211 rotates with it, so that the liquid moves toward the filter cover 213 under the action of centrifugal force, thereby achieving the filtration of particulate residue.

[0036] The interior of the sandwich-type reflux hood 212 is divided into several independent areas by partitions. On the one hand, it can form a straw-like structure, allowing the independent area at the bottom to independently draw liquid under negative pressure. On the other hand, when the independent area rotates from the bottom to the top, it can also transfer the liquid at the bottom of the pipe to the top, and then let it enter the centrifuge chamber 211 under the action of gravity.

[0037] The dual filtration assembly 22 includes a filter cake chamber 221, an outer fixed cover 222, and an adsorbent material 223. The filter cake chamber 221 is fixed to the water tank 11, the filter cover 213 is fixed to the filter cake chamber 221, the outer fixed cover 222 is fixed to the water tank 11, and the adsorbent material 223 is disposed in the outer fixed cover 222. Particulate residue enters the filter cake chamber 221 after being filtered by the filter cover 213, while powdered sludge is adsorbed in the adsorbent material 223.

[0038] The filter chamber 221 and the adsorbent material 223 can collect dirt of two different particle sizes, residue and powder, to filter the water and then recycle it into the water tank 11. This reuse method can greatly reduce the amount of water used in the cleaning process compared with conventional rinsing methods.

[0039] The cleaning drive assembly 3 includes a drive motor 31, a cleaning wheel 32, and a wire brush 33. The drive motor 31 is mounted on the water tank 11, and the output shaft of the drive motor 31 is located at one end of the hollow shaft 12. The cleaning wheel 32 is located outside the other end of the hollow shaft 12, and the wire brush 33 is mounted on the cleaning wheel 32.

[0040] The water spray assembly 4 includes a diverter head 41, a hose 42, and a nozzle 43. The diverter head 41 is located at the other end of the hollow shaft 12 and is connected to the hollow shaft 12. The nozzle 43 is fixed to the cleaning wheel 32 by a bracket. The hose 42 is located between the diverter head 41 and the nozzle 43.

[0041] The travel support assembly 5 includes a roller support 51, a swing arm 52, a preload spring 53, and a travel wheel 54. The swing arm 52 is hinged to the roller support 51, the preload spring 53 is located between the roller support 51 and the swing arm 52, and the travel wheel 54 is located at the end of the swing arm 52.

[0042] The travel support assembly 5 also includes a mounting ring 55, which is disposed on the water tank 11. One set of roller supports 51 is disposed outside the outer fixing cover 222, and the other set of roller supports 51 is disposed outside the mounting ring 55.

[0043] The elastic modulus of the lower preload spring 53 is greater than that of the upper preload spring 53.

[0044] With the support of the travel support assembly 5, the hollow shaft 12 is always located near the central axis of the pipe.

[0045] The top of the water tank 11 is equipped with a one-way exhaust valve. When the internal air pressure of the water tank 11 is higher than that of the outside, the gas in the water tank 11 can be discharged to the outside. When the internal air pressure of the water tank 11 is lower than that of the outside, the gas can only enter the water tank 11 through the dual circulation filter mechanism 2.

[0046] like Figure 4As shown, the dashed line represents the boundary outline of the pipeline. This device is coaxially arranged with the pipeline and located inside the pipeline.

[0047] like Figure 9 As shown, the arrows indicate the flow direction of the liquid in the dual circulation filtration mechanism 2, and the dotted lines represent the baffles with filtration function, which allow the liquid to pass through but do not allow particulate impurities to pass through; when the water collecting auger 13 and the centrifugal plate 2111 rotate, they will generate negative pressure inside the centrifugal chamber 211. The magnitude of the negative pressure is related to factors such as the rotation speed, tilt angle design, and density of the two, and can be designed according to requirements. Since the interior of the sandwich-type reflux hood 212 is divided into several independent areas by inclined baffles, the independent area located at the bottom can independently extract liquid under negative pressure; when the independent area rotates from the bottom to the top, it can also transfer the liquid located at the bottom of the pipe to the top, and then let it enter the centrifuge chamber 211 under the action of gravity.

[0048] In practical use, the user first needs to fill the water tank 11 with water and then send the device into the target pipeline. Then, while starting the drive motor 31, the device is slowly pushed forward in the pipeline by the traveling wheel 54. Since the water of this device is stored in the water tank 11, it does not need to be connected to the outside through a water pipe. Therefore, when cleaning long-distance pipelines, there is no water loss in the water supply pipe as in conventional solutions.

[0049] The drive motor 31 rotates the water collecting auger 13 via the hollow shaft 12, which can push the liquid in the water tank 11 toward the direction of the water inlet window 121 and increase the water pressure. Through the variable diameter design of the water tank 11 and the water collecting auger 13, the technical effect of supplying water toward the water inlet window 121 can still be maintained when the water storage in the water tank 11 decreases.

[0050] When the hollow shaft 12 rotates, it can rotate the cleaning wheel 32, and at the same time clean the inner wall of the pipe with the wire brush 33; the liquid enters the diverter head 41 through the inside of the hollow shaft 12, and is sprayed onto the inner wall of the pipe through the nozzle 43. Depending on the speed of the device, the water sprayed onto the top wall of the pipe may directly enter the sandwiched return shroud 212, or it may first accumulate naturally at the bottom of the pipe and then enter the sandwiched return shroud 212.

[0051] When the water collecting auger 13 and the centrifugal plate 2111 rotate, they will generate negative pressure inside the centrifugal chamber 211. Since the interior of the jacketed reflux hood 212 is divided into several independent areas by the inclined baffle, the independent area located at the bottom can independently extract liquid under the action of negative pressure. When the independent area rotates from the bottom to the top, it can also transfer the liquid located at the bottom of the pipe to the top, and then let it enter the centrifugal chamber 211 under the action of gravity.

[0052] After the liquid enters the centrifuge chamber 211, it will rotate with the centrifuge plate 2111 and impact the filter cover 213 under the action of centrifugal force and gravity. At this time, the particulate residue will enter the filter cake chamber 221 along the filter cover 213, and the water and mud powder will enter the outer fixed cover 222 through the filter cover 213. When the liquid passes through the adsorbent material 223, the mud powder will be filtered off, and the relatively clean water will re-enter the water bag 11 for recycling.

[0053] Although this solution cannot recover all the water, it can greatly reduce water consumption compared to conventional solutions. By filling the water tank 11 with enough water in advance according to the inner diameter and length of the pipe, the internal cleaning of long pipes can be achieved without connecting to an external water source.
