Description

Technical Field

[0001] The invention relates to the technical field of pipelines, in particular to an anti-clogging water supply pipeline of a waterworks. Background Art

[0002] As an important part of urban infrastructure, the stability and efficiency of tap water supply pipelines are directly related to the quality of daily water use and quality of life of residents. However, in the process of tap water supply, the problem of water supply pipeline blockage has always been a difficult problem that cannot be ignored. The existence of this problem not only affects the smoothness of water supply, but may also cause a series of problems such as water pollution and water pressure drop, causing inconvenience to residents' lives. At present, there are a variety of anti-blockage technologies and products on the market to address the problem of water supply pipeline blockage, such as adding a filtering structure in the water supply pipeline to filter impurities in tap water.

[0003] The patent document with announcement number CN212417159U discloses a water supply pipe for anti-clogging tap water. The anti-clogging tap water supply pipe is provided with a first anti-clogging mechanism and a second anti-clogging mechanism. The two anti-clogging mechanisms can filter impurities and garbage in the input pipe, so that the impurities and garbage are respectively retained in the filter screen and the filter screen plate, and the staff can take out the filter screen and the filter screen plate and clean them, so that the filtering effect of the two anti-clogging mechanisms is long-lasting and effective, avoiding the situation where impurities clog the pipe. There will be no problem of pipe clogging in subsequent transportation, which effectively solves the problem of impurities in tap water clogging the water supply pipe.

[0004] Although the above patent document filters impurities and garbage in tap water through filter screens and filter screen plates, as the use time of the filter screen increases, more impurities adhere to the filter screen, the mesh on the filter screen is blocked, and the resistance of tap water flowing through the filter screen increases. As the subsequent tap water continues to be input, the water pressure at the filter screen gradually increases. When the water pressure increases to a certain level, the tap water will squeeze out the impurities in the mesh, causing damage to the filter screen, allowing the impurities to continue to flow with the tap water.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a processing pipeline and two intercepting devices. The provision of the two intercepting devices realizes multi-stage filtration of tap water and improves filtration efficiency. The opening and closing structure in the intercepting device located in the front collects the two filter components into the two processing chambers respectively, and the intercepting device located in the rear continues to work to ensure the continuity of tap water filtration.

[0018] 2. The present invention is provided with two partition plates and two pushing structures.

[0019] 3. The present invention is provided with a drain valve. When the partition plate completely cuts off the connection between the rear of the filter and the processing pipeline, the drain valve opens, the water outlet becomes unobstructed, and the water pressure in the processing chamber begins to drop, forming a pressure difference from the filter to the water outlet. Due to the reduced water pressure and suction at the water outlet, the tap water begins to flow toward the water outlet. In this process, the tap water not only fills the space in the processing chamber, but also impacts the filter at a higher flow rate, flushing down the impurities attached to the filter. The tap water carrying the impurities is then guided by the suction of the water flow at the water outlet, further accelerating to flow to the water outlet, and finally discharged from the processing system, thereby realizing cleaning by utilizing the fluidity and pressure difference of the tap water itself, without the need for additional energy consumption or addition of detergents, which is in line with the concept of energy saving and environmental protection.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 13As shown: a blockage-proof water supply pipeline of a waterworks, comprising a treatment pipeline 1 connected to a water supply line through two flanges, the treatment pipeline 1 having a first end and a second end, and tap water flows from the first end to the second end, and also comprising at least two interception devices arranged on the treatment pipeline 1, the interception device comprising two treatment chambers 2, a filtering structure 3, an opening and closing structure 4 and a cleaning structure 6; the two treatment chambers 2 are symmetrically arranged on both sides of the treatment pipeline 1, and the two treatment chambers 2 are connected to the treatment pipeline 1; the filtering structure 3 comprises a rectangular guide track 31 and two filtering assemblies 32, the two ends of the rectangular guide track 31 are respectively connected to the two treatment chambers 2, the rectangular guide track 31 comprises two parallel first plates 311, the two first plates 311 are respectively abutted against the two treatment chambers 2, two first guide cross bars 312 are parallelly arranged between the two first plates 311, and the two filter assemblies 32 are connected to the two treatment chambers 2. The filter components 32 are all slidingly arranged on the rectangular guide rail 31, and the filter components 32 include a second plate body 321 and a third plate body 322 arranged in parallel. The second plate body 321 is fixedly connected to the first plate body 311, and the third plate body 322 is slidingly connected to the second guide cross bar 522. A filter screen 323 is arranged between the second plate body 321 and the third plate body 322, and the filter screen 323 faces the flow direction of tap water; the opening and closing structure 4 is arranged on one side of the processing pipeline 1, and the opening and closing structure 4 is used to drive the two filter components 32 to approach or move away from each other. When the two filter components 32 abut against each other, the tap water must flow through the two filter components 32. When the two filter components 32 are away from each other, the two filter components 32 are respectively located inside the two processing chambers 2; the cleaning structure 6 is arranged in the two processing chambers 2, and the cleaning structure 6 is used to process the two filter components 32 in the two processing chambers 2.

[0036] In the traditional tap water supply pipeline, a filter 323 is added to filter impurities in the tap water to prevent the pipeline from being blocked. However, as the impurities intercepted and filtered by the filter 323 increase, the flow resistance of the filter 323 to the tap water increases, and the flow rate of the tap water at the filter 323 decreases. Under the squeezing effect of the subsequent tap water, the water pressure at the filter 323 increases, resulting in an increase in the pressure on the filter 323. Excessive water pressure can easily carry away the impurities on the filter 323, and is more likely to cause damage to the filter 323. At least two interception devices are provided, each of which includes two processing chambers 2, a filtering structure 3, an opening and closing structure 4 and a cleaning structure 6. The filtering structure 3 is realized by a rectangular guide rail 31 and two slidable filtering components 32. The filtering component 32 is embedded with the filter 323 to intercept impurities in the tap water. The opening and closing structure 4 can control the opening and closing of the filtering component 32 as needed. When the filter components 32 are in contact with each other, the water flow is completely blocked to achieve efficient filtration. The interception device near the first end of the processing pipe 1 first intercepts most of the impurities, and then the two filter components 32 are moved into the two processing chambers 2 for cleaning through the opening and closing operation, while the subsequent interception device continues to work to ensure the filtering effect on the tap water. The cleaning structure 6 cleans the filter components 32 moved into the processing chamber 2, and at the same time, the tap water in the processing pipe 1 is diverted into the processing chamber 2. Under the impact of tap water and the cleaning effect of the cleaning structure 6, the debris on the filter screen 323 is cleaned, and the impurities and waste water that are impacted and dropped are discharged from the processing chamber 2. Then the opening and closing structure 4 drives the two filter components 32 to abut against each other, and the two filter components 32 intercept and filter the tap water again, thereby preventing impurities from being squeezed through the filter screen 323 by high-pressure tap water, ensuring the filtering effect on tap water and preventing pipeline blockage.

[0037] Reference Figure 3 , Figure 5 and Figure 6As shown: the interception device also includes a partition structure 5, the partition structure 5 includes two partition plates 51 and two pushing structures 52; the two partition plates 51 are respectively arranged between the processing pipeline 1 and the two processing chambers 2, and the partition plates 51 are used to change the size of the communication port between the processing pipeline 1 and the processing chamber 2; the two pushing structures 52 correspond to the two partition plates 51 respectively, and the pushing structure 52 is used to push the partition plates 51 to move, and the pushing structure 52 includes a cover body 521, and the cover body 521 is covered on one side of the processing pipeline 1, and a plurality of second parallel guide cross bars 522 are arranged in the cover body 521, and The axial direction of the second guide cross bar 522 is parallel to the moving direction of the partition plate 51, and a push plate 523 is also provided in the cover body 521. One side of the push plate 523 is connected to the partition plate 51, and the push plate 523 is slidably connected to the second guide cross bar 522. A first spring 524 is sleeved on the second guide cross bar 522, and the two ends of the first spring 524 are respectively abutted against the inner wall of the cover body 521 and the push plate 523. The first rotating shaft 525 is provided in the cover body 521, and the two ends of the first rotating shaft 525 are respectively connected to the upper and lower ends of the cover body 521, and the first rotating shaft 525 is installed with a cam 526.

[0038] Since the processing chamber 2 is connected to the processing pipeline 1, the tap water enters the processing chamber 2 from the front of the filter screen 323. After knocking off the debris on the filter screen 323, the tap water may carry impurities and flow back to the processing pipeline 1 from the back of the filter screen 323. By setting the partition structure 5, the partition plate 51 is set between the processing pipeline 1 and the processing chamber 2 to adjust the size of the connecting port between the two. When the two filter components 32 enter the two processing chambers 2 respectively, the two pushing structures 52 work at the same time, the first rotating shaft 525 rotates to drive the cam 526 to rotate 90 degrees, and the raised end of the cam 526 pushes the push plate 523 moves along the second guide cross bar 522, compressing the first spring 524, and the push plate 523 drives the partition plate 51 to move from the rear of the filter screen 323 toward the filter screen 323 until the connection between the rear of the filter screen 323 and the processing pipe 1 is completely cut off. After the partition plate 51 is cut off, the cleaning structure 6 starts to work, and uses the impact of tap water and the action of the cleaning structure 6 to remove impurities on the filter screen 323. The impurities flow with the water into the processing chamber 2 behind the filter screen 323 and are discharged from the processing chamber 2 through the partition connection port, thereby ensuring the unidirectional flow of impurities during the cleaning process, making the cleaning process more efficient and thorough.

[0039] Reference Figure 3 and Figure 7 As shown: the processing chamber 2 includes a chamber body 21, an end cover 22 and a drain valve 23; one end of the chamber body 21 is connected to the processing pipeline 1, and a water outlet 211 is opened on the chamber body 21; the end cover 22 is covered at the other end of the chamber body 21; the drain valve 23 is arranged at the water outlet 211, and the drain valve 23 is used to open or close the water outlet 211.

[0040] When the filter assembly 32 is in filtering action, the drain valve 23 closes the water outlet 211 to prevent the tap water from being discharged from the water outlet 211. When the partition plate 51 completely cuts off the connection between the rear of the filter screen 323 and the processing pipeline 1, the drain valve 23 opens and the water outlet 211 becomes unobstructed. At this time, the water pressure in the processing chamber 2 begins to drop, forming a pressure difference from the filter screen 323 to the water outlet 211. Due to the water pressure reduction and suction at the water outlet 211, the tap water begins to flow toward the water outlet 211. In this process, the tap water not only fills the space in the processing chamber 2, but also impacts the filter screen 323 at a higher flow rate, flushing the impurities attached to the filter screen 323. The tap water carrying the impurities is then guided by the suction of the water flow at the water outlet 211, further accelerating to flow to the water outlet 211, and finally discharged from the processing system, thereby realizing the use of the fluidity and pressure difference of the tap water itself for cleaning, without the need for additional energy consumption or addition of detergents, which is in line with the concept of energy saving and environmental protection.

[0041] Reference Figure 5 and Figure 8 As shown: the partition structure 5 also includes a first driving structure 53, which is arranged between the two pushing structures 52. The first driving structure 53 is used to drive the two pushing structures 52 to work simultaneously. The first driving structure 53 includes a second double-headed screw 531, two second moving blocks 532, two first gears 533 and two first racks 534. The two ends of the second double-headed screw 531 are respectively facing the two first rotating shafts 525, the two second moving blocks 532 are respectively arranged at the two ends of the second double-headed screw 531, the two first gears 533 are respectively connected to the two first rotating shafts 525, the two first racks 534 are respectively installed on the two second moving blocks 532, and the two first racks 534 are respectively meshed with the two first gears 533.

[0042] After the two filter assemblies 32 are respectively received into the two processing chambers 2, the first driving structure 53 works, the second double-headed screw 531 rotates to drive the two second moving blocks 532 away from each other, the two second moving blocks 532 respectively drive the two first racks 534 away from each other, the two first racks 534 respectively drive the two first gears 533 to rotate in opposite directions, the first rack 534 drives the first gear 533 to rotate 90 degrees, and the first gear 533 drives the first rotating shaft 525 to rotate 90 degrees. Since there is no relative sliding between the second moving block 532 and the second double-headed screw 531, and between the first gear 533 and the first rack 534, the synchronization and accuracy of the two partition plates 51 during the movement are ensured.

[0043] Reference Figure 3 and Fig. 9As shown: the cleaning structure 6 includes two transmission structures 61 and two reverse moving structures 62; the two transmission structures 61 correspond to the two ends of the rectangular guide track 31 respectively, the transmission structure 61 includes two connecting rods 611, the two connecting rods 611 are arranged in parallel, and the two connecting rods 611 are respectively located on both sides of the central axis of the rectangular guide track 31, and one end of the connecting rod 611 extends out of the processing bin 2; the two reverse moving structures 62 are respectively arranged on the outside of the two processing bins 2, the reverse moving structure 62 includes a second gear 621, a second rotating shaft 622 and two second racks 623, the second gear 621 is located between the two connecting rods 611, the end of the second rotating shaft 622 is connected to the second gear 621, the middle part of the second rotating shaft 622 is connected to the processing bin 2, the two second racks 623 are respectively connected to the two connecting rods 611, and the two second racks 623 are both engaged with the second gear 621.

[0044] Under normal circumstances, the filter screen 323 is located in the processing chamber 2, and the processing chamber 2 is completely divided into two parts, ensuring that tap water can only flow through one side of the filter screen 323 to prevent impurities from entering the back of the filter screen 323. When cleaning the filter screen 323, impurities cannot pass through the filter screen 323 to reach the back of the filter screen 323. By setting two transmission structures 61 and two reverse moving structures 62, the two reverse moving structures 62 work at the same time. As the second rotating shaft 622 rotates, the second gear 621 starts to swing. Since the position of the second gear 621 is fixed and located between the two connecting rods 611, the second gear 621 will simultaneously apply forces in opposite directions to the two second racks 623. The two second racks 623 are respectively connected to the two The connecting rod 611 is connected, so the two second racks 623 will push and pull the connecting rod 611 respectively. With the reciprocating swing of the second gear 621, the two connecting rods 611 move alternately. The movement of the two connecting rods 611 drives the rectangular guide track 31 to swing around the central axis of the rectangular guide track 31, thereby causing the filter screen 323 to swing as well. When the filter screen 323 swings to an inclined state, a gap will appear between the filter screen 323 and the processing bin 2, allowing tap water to drive impurities to flow through the gap to the rear of the filter screen 323. At the same time, the continuously swinging filter screen 323 can use inertia to shake off the impurities attached to the filter screen 323, thereby realizing the automatic swing of the filter screen 323 and effectively removing impurities attached to the screen surface.

[0045] Reference Fig. 9 and Fig.10As shown: the cleaning structure 6 also includes a swinging structure 63, the swinging structure 63 includes a horizontal moving rod 631, a guide structure 632 and two swinging connecting structures 633; ​​the horizontal moving rod 631 is arranged above the processing pipeline 1; the guide structure 632 has at least two, and the two guide structures 632 are used to limit the moving direction of the horizontal moving rod 631, and the guide structure 632 includes a fourth guide cross bar 6321, and the horizontal moving rod 631 is slidably connected to the fourth guide cross bar 6321; there are two swinging connecting structures 633, and the two swinging connecting structures 633 are respectively arranged at both ends of the horizontal moving rod 631, and the swinging connecting structure 633 connects the horizontal moving rod 631 with the second rotating shaft 622.

[0046] If the forces applied by the two reverse moving structures 62 to the two ends of the rectangular guide rail 31 are not synchronized, the rectangular guide rail 31 will be deformed. By setting a swing structure 63, the two guide structures 632 are used to limit the moving direction of the horizontal moving rod 631 to ensure that it translates along a predetermined trajectory. When the horizontal moving rod 631 slides along the fourth guide cross bar 6321, the swing connection structures 633 at both ends of the horizontal moving rod 631 move synchronously. The two swing connection structures 633 simultaneously drive the two reverse moving structures 62 to work, so that the two transmission structures 61 synchronously transmit the same force to the two ends of the rectangular guide rail 31, thereby achieving simultaneous force on both ends of the rectangular guide rail 31 and avoiding deformation of the rectangular guide rail 31.

[0047] Reference Fig. 9 and Fig.10 As shown: the swing connection structure 633 includes a swing rod 6331 and a connecting block 6332; one end of the swing rod 6331 is connected to the end of the second rotating shaft 622; the connecting block 6332 is slidably arranged on the swing rod 6331, and the end of the connecting block 6332 is axially connected to the end of the horizontal moving rod 631.

[0048] During the reciprocating movement of the horizontal moving rod 631, the distance between the horizontal moving rod 631 and the second rotating shaft 622 will constantly change. The design of the swing connection structure 633 allows the connecting block 6332 to slide on the swing rod 6331, and the connecting block 6332 can rotate around the axial connection between it and the horizontal moving rod 631, and can adjust the length of the force arm applied to the second rotating shaft 622 by the horizontal moving rod 631 through the swing rod 6331 in real time, ensuring stable transmission efficiency and force balance in different positions, and realizing complex force transmission and adjustment functions through simple axial connection and sliding connection, thereby reducing the complexity of the overall structure and the manufacturing cost.

[0049] Reference Fig. 9 and Fig.11As shown: the transmission structure 61 also includes a sliding connection structure 612, which connects the two connecting rods 611 to the rectangular guide track 31. The sliding connection structure 612 includes a third guide cross bar 6121 and two third moving blocks 6122. The third guide cross bar 6121 is connected to the second plate body 321. The two third moving blocks 6122 are slidably set on the third guide cross bar 6121, and the two third moving blocks 6122 are respectively hinged to the two connecting rods 611.

[0050] If the two connecting rods 611 are in contact with the second plate 321, the connecting rod 611 extending out of the processing chamber 2 cannot apply a force to the second plate 321, and only the connecting rod 611 extending into the processing chamber 2 can apply a force to the second plate 321. If the two connecting rods 611 are connected to the second plate 321, the connection position of the two connecting rods 611 and the second plate 321 is changing. By setting a sliding connection structure 612, the two connecting rods 611 are hinged to the two third moving blocks 6122, and the two third moving blocks 6122 are connected to the second plate 321 through the third guide cross bar 6121. When the second plate body 321 is connected, the two third moving blocks 6122 move along the third guide cross bar 6121 during the swinging process of the second plate body 321, so as to keep the positions of the two connecting rods 611 unchanged. When the connecting rods 611 are extended or extended into the processing chamber 2, the connecting rods 611 can exert a force on the second plate body 321, thereby avoiding the problem of force interruption or instability caused by the change of the movement state of the connecting rods 611, thereby ensuring that the two connecting rods 611 and the second plate body 321 maintain effective connection and force transmission, making the operation of the entire transmission system more reliable and efficient.

[0051] Reference Figure 3 , Fig.12 and Fig.13 As shown: the opening and closing structure 4 includes a first double-headed screw 41, two first moving blocks 42, a rotation driver 43 and a fixed structure 44; one end of the first double-headed screw 41 extends into the interior of the processing pipeline 1 and passes through the rectangular guide track 31; the two first moving blocks 42 are respectively arranged at both ends of the first double-headed screw 41, and the two first moving blocks 42 correspond to two filter components 32 respectively; the rotation driver 43 is arranged at one end of the first double-headed screw 41, and the rotation driver 43 is used to drive the first double-headed screw 41 to rotate; the fixed structure 44 is arranged On the processing chamber 2, a fixed structure 44 is used to fix the rotating driver 43. The fixed structure 44 includes a mounting plate 441. The rotating driver 43 is fixed on the mounting plate 441. A plurality of fixed arms 442 are arranged in a circular array around the mounting plate 441. Insert rods 443 are arranged on the fixed arms 442. A fixing ring 444 is also arranged around the mounting plate 441. The fixing ring 444 is coaxially arranged with the first double-headed screw 41, and the fixing ring 444 is provided with a plurality of sockets 4441 corresponding to the insert rods 443 on the plurality of fixed arms 442.

[0052] The rotary driver 43 drives the first double-headed screw 41 to rotate, and the first double-headed screw 41 drives the two first moving blocks 42 to move away from each other, and the first moving block 42 drives the third plate 322 to move toward the second plate 321. When the cleaning structure 6 swings the filter assembly 32, the first moving block 42 drives the first double-headed screw 41 to swing at the same time, and the rotary driver 43 needs to swing synchronously with the first double-headed screw 41 to ensure the driving accuracy of the rotary driver 43 on the first double-headed screw 41. Therefore, the rotary driver 43 drives the first double-headed screw 41 to move away from each other. The first double-headed screw 41 needs to remain fixed when rotating. By setting a fixed structure 44, the rotation driver 43 drives several fixed arms 442 to swing through the mounting plate 441 when swinging. When the rotation driver 43 needs to drive the first double-headed screw 41 to rotate, the insertion rod 443 on the fixed arm 442 is inserted into the insertion hole 4441 on the fixing ring 444, so that the mounting plate 441 cannot rotate around the axis of the first double-headed screw 41, thereby ensuring the driving accuracy of the first double-headed screw 41 by the rotation driver 43.

[0053] Reference Fig.12 and Fig.13 As shown: the opening and closing structure 4 also includes a supporting structure 45, which is covered on the outside of the rotating driver 43. The supporting structure 45 includes an annular supporting track 451 and a plurality of rollers 452. The annular supporting track 451 covers a plurality of fixed arms 442 inside thereof, and the plurality of rollers 452 are respectively arranged at the ends of the plurality of fixed arms 442, and the rollers 452 abut against the inner wall of the annular supporting track 451.

[0054] The rotary driver 43 is affected by the centrifugal force and gravity during the swinging process, which may cause the connection between the rotary driver 43 and the first double-headed screw 41 to bend. By setting the support structure 45, when the fixed arm 442 swings around the axis of the first double-headed screw 41, the fixed arm 442 drives the roller 452 to roll along the inner wall of the annular support track 451. The annular support track 451 applies a force toward the axis of the first double-headed screw 41 to the fixed arm 442 through the roller 452, thereby limiting the downward force on the connection between the rotary driver 43 and the first double-headed screw 41, thereby enhancing the stability of the overall structure.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
