Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pipeline internal cleaning, and particularly relates to a circulating water-saving pipeline installation cleaning machine. BACKGROUND

[0002] The internal cleaning of a long pipeline is generally performed by sending a cleaning machine into the interior of the pipeline, allowing the cleaning machine to travel in the pipeline and clean the inner wall. In a conventional scheme, the tail of the cleaning machine needs to be connected to a water pipe leading to the outside to ensure water supply. However, this approach has the problems of large water consumption and serious water waste, as follows:

[0003] A: Water resources are generally used only once, and the total consumption is large;

[0004] B: After cleaning, a water removal process needs to be added due to the large amount of water accumulated in the pipeline;

[0005] C: To supply water to the equipment through the water supply pipe, the water supply pipe needs to be filled first, and this part of water is wasted. The longer the pipeline, the more serious the water waste in the water supply pipe. SUMMARY

[0006] To overcome the defects of the prior art, the present application provides a circulating water-saving pipeline installation cleaning machine. The present application replaces the water supply pipe with a water bag, so that water waste does not increase with the length of the pipeline. The present application also uses a circulating filtration method to reuse water, which greatly reduces water consumption compared to conventional schemes.

[0007] Furthermore, to maintain the technical effect of automatic water supply of the hollow shaft, the present application also provides a water bag with a variable diameter structure and a water collecting auger.

[0044] As Figures 1-8 shown, the present application proposes a circulating water-saving type pipeline installation cleaning machine, which comprises a water collection booster assembly 1, a double circulation filtering mechanism 2, a cleaning drive assembly 3, a water spraying assembly 4 and a travel support assembly 5, the double circulation filtering mechanism 2 is arranged on the water collection booster assembly 1, the cleaning drive assembly 3 is arranged at the end of the water collection booster assembly 1, the water spraying assembly 4 is arranged on the cleaning drive assembly 3, and the travel support assembly 5 is arranged on the water collection booster assembly 1 and the double circulation filtering mechanism 2;

[0045] The water collecting and pressurizing assembly 1 comprises a water bag 11, a hollow shaft 12 and a water collecting auger 13, the hollow shaft 12 is rotationally arranged in the water bag 11, the water collecting 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 water bag 11 near the water inlet window 121 gradually decreases, and the cross-sectional profile of the water collecting auger 13 corresponds to that of the water bag 11.

[0046] When the hollow shaft 12 rotates with the water collecting auger 13, the water in the water bag 11 can be extruded to enter the inside of the hollow shaft 12 through the water inlet window 121 and be transported towards the water spraying assembly 4; through the variable-diameter design of the water bag 11 and the water collecting auger 13, when the water storage capacity in the water bag 11 decreases, the technical effect of supplying water towards the water inlet window 121 can still be maintained.

[0047] The double circulation filtering mechanism 2 comprises a backflow collecting assembly 21, a double filtering assembly 22 and a one-way valve piece 23, the backflow collecting assembly 21 is arranged on the hollow shaft 12, the double filtering assembly 22 is arranged on the side of the water bag 11, one side of the water bag 11 is provided with a water inlet hole 111, the one-way valve piece 23 is arranged at the water inlet hole 111, the one-way valve piece 23 is provided with an elastic part 231, and the elastic part 231 covers the inner side of the water inlet hole 111.

[0048] The one-way valve piece 23 can allow liquid to enter the water bag 11 through the water inlet hole 111 by deformation of the elastic part 231, but cannot allow liquid in the water bag 11 to be discharged from the water inlet hole 111.

[0049] The backflow collecting assembly 21 comprises a centrifugal chamber 211, a sandwiched backflow cover 212 and a filtering cover 213, the centrifugal chamber 211 is fixedly connected to the hollow shaft 12, the inside of the centrifugal chamber 211 is arrayed with centrifugal plates 2111, the sandwiched backflow cover 212 is fixedly connected to the hollow shaft 12, the end of the sandwiched backflow cover 212 abuts against the inner wall of the pipeline and is made of flexible material, the inside of the sandwiched backflow cover 212 is divided into a plurality of independent areas by inclined partition plates, and the filtering cover 213 is arranged on the double filtering assembly 22.

[0050] When the centrifugal plates 2111 rotate, the liquid in the centrifugal chamber 211 can follow the rotation, so that the liquid moves towards the filtering cover 213 under the action of centrifugal force, thereby realizing the filtration of particle residues.

[0051] The inside of the sandwiched backflow cover 212 is divided into a plurality of independent areas by the partition plates, on the one hand, a structure similar to a straw can be formed, so that the independent area located below can independently extract liquid under the action of negative pressure; on the other hand, when the independent area rotates from below to above, the liquid located below the pipeline can also be transferred to above, and then enter the centrifugal chamber 211 under the action of gravity.

[0052] The double filtering assembly 22 comprises a filter residue chamber 221, an outer fixing cover 222 and an adsorbing material 223. The filter residue chamber 221 is fixed to the water bag 11, the filtering cover 213 is fixed to the filter residue chamber 221, the outer fixing cover 222 is fixed to the water bag 11, and the adsorbing material 223 is arranged in the outer fixing cover 222. The granular residue enters the filter residue chamber 221 after being filtered by the filtering cover 213, and the powder sludge is adsorbed in the adsorbing material 223.

[0053] The filter residue chamber 221 and the adsorbing material 223 can respectively collect the residue and the powder of different particle sizes, realize the filtration of the water, and then make the water enter the water bag 11 for recycling. Compared with the conventional flushing scheme, the repeated use can greatly reduce the water consumption of the cleaning process.

[0054] The cleaning driving assembly 3 comprises a driving motor 31, a cleaning wheel 32 and a steel wire brush 33. The driving motor 31 is arranged on the water bag 11, the output shaft of the driving motor 31 is arranged at one end of the hollow shaft 12, the cleaning wheel 32 is arranged outside the other end of the hollow shaft 12, and the steel wire brush 33 is arranged on the cleaning wheel 32.

[0055] The water spraying assembly 4 comprises a flow divider 41, a hose 42 and a spray head 43. The flow divider 41 is arranged at the other end of the hollow shaft 12 and penetrates the hollow shaft 12, the spray head 43 is fixed to the cleaning wheel 32 through a support, and the hose 42 is arranged between the flow divider 41 and the spray head 43.

[0056] The traveling support assembly 5 comprises a roller support 51, a swing arm 52, a pre-pressing spring 53 and a traveling wheel 54. The swing arm 52 is hinged to the roller support 51, the pre-pressing spring 53 is arranged between the roller support 51 and the swing arm 52, and the traveling wheel 54 is arranged at the end of the swing arm 52.

[0057] The traveling support assembly 5 further comprises a mounting ring 55 arranged on the water bag 11. One group of the roller supports 51 is arranged outside the outer fixing cover 222, and the other group of the roller supports 51 is arranged outside the mounting ring 55.

[0058] The elastic modulus of the pre-pressing spring 53 located at the lower side is greater than that of the pre-pressing spring 53 located at the upper side.

[0059] Under the support of the traveling support assembly 5, the hollow shaft 12 is always located near the central axis of the pipeline.

[0060] A one-way exhaust valve is arranged at the top of the water bag 11. When the internal air pressure of the water bag 11 is higher than the external air pressure, the gas in the water bag 11 can be exhausted to the outside. When the internal air pressure of the water bag 11 is lower than the external air pressure, the gas can only enter the water bag 11 through the double circulation filtering mechanism 2.

[0061] As Figure 4As shown, the dashed line represents the boundary profile of the pipeline, the device is coaxial with the pipeline and located inside the pipeline.

[0062] As shown, the arrow represents the flow direction of the liquid in the double-circulation filtering mechanism 2, and the dashed part represents the partition with filtering function, i.e. allowing the liquid to pass through but not allowing the particulate impurities to pass through; the rotation of the water collecting auger 13 and the centrifugal plate 2111 will generate negative pressure inside the centrifugal chamber 211, and the size of the negative pressure is related to the rotation speed, inclination angle design, density and other factors, which can be designed according to the requirements. Figure 9

[0063] Since the inside of the sandwich type reflux cover 212 is divided into several independent areas by the inclined partition, the independent area located below can independently extract the liquid under the action of negative pressure; when the independent area rotates from below to above, it can also transfer the liquid below the pipeline to above, and then make it enter the centrifugal chamber 211 under the action of gravity.

[0064] In specific use, first, the user needs to fill the water bag 11 with water, then put the device into the target pipeline, and then start the driving motor 31 while making the device slowly advance in the pipeline through the traveling wheel 54. Since the water storage of the device is in the water bag 11, it does not need to be connected with the outside through a water pipe, so there is no water loss in the water supply pipe in the conventional scheme when cleaning a long-distance pipeline.

[0065] The driving motor 31 rotates with the water collecting auger 13 through the hollow shaft 12, which can push the liquid in the water bag 11 towards the direction of the water inlet window 121 and increase the water pressure. Through the variable diameter design of the water bag 11 and the water collecting auger 13, when the water storage in the water bag 11 decreases, the technical effect of supplying water to the water inlet window 121 can still be maintained.

[0066] The hollow shaft 12 can rotate with the cleaning wheel 32, and at the same time, the inner wall of the pipeline can be cleaned through the steel wire brush 33; the liquid enters the flow divider 41 through the inside of the hollow shaft 12, and is sprayed on the inner wall of the pipeline through the spray head 43;

[0067] According to the different advancing speed of the device, the water sprayed on the top wall of the pipeline may directly enter the sandwich type reflux cover 212, or may first accumulate naturally at the bottom of the pipeline and then enter the sandwich type reflux cover 212.

[0068] The rotation of the water collecting auger 13 and the centrifugal plate 2111 will generate negative pressure inside the centrifugal chamber 211, and since the inside of the sandwich type reflux cover 212 is divided into several independent areas by the inclined partition, the independent area located below can independently extract the liquid under the action of negative pressure; when the independent area rotates from below to above, it can also transfer the liquid below the pipeline to above, and then make it enter the centrifugal chamber 211 under the action of gravity.​

[0069] After the liquid enters the centrifugal chamber 211, it will rotate with the centrifugal plate 2111, and will hit the filter cover 213 under the action of centrifugal force and gravity. At this time, the particle residue will enter the residue 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. The mud powder will be filtered when the liquid passes through the adsorption material 223, and the relatively clean water will re-enter the water bag 11 for recycling.

[0070] Although this scheme cannot recover all the water, it can greatly reduce the consumption of water compared with the conventional scheme. According to the inner diameter and length of the pipeline, enough water can be poured into the water bag 11 in advance, so that the internal cleaning of the long pipeline can be realized without connecting to external water sources.

[0071] It should be noted that, in this document, the terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any actual such relationship or order between the entities or operations.
