Description

Technical Field

[0002] Drainage pipes can be broadly understood as pipe systems used to discharge and drain various fluids (including water, sewage, exhaust gas, etc.). During the operation of the drainage pipes, dirt, sediment and microorganisms will grow in the drainage pipes. Therefore, a self-cleaning device will be installed in the pipes to keep the pipes clean and operate efficiently.

[0003] The patent document with announcement number CN113863468B discloses a self-cleaning pipe for water conservancy projects, in which a filter group connected to a pull rod through a transmission assembly is arranged inside the pipe, and a cleaning piece is installed on the pull rod. By pulling the pull rod, the filter group can be driven to swing inside the pipe. At the same time, the cleaning piece cleans the inner wall of the pipe with the movement of the pull rod. The filter group can perform secondary filtration on the water flow entering the pipe. The filter group can shake off impurities intercepted on the filter during the swing of the pull rod and discharge them through the sewage pipe.

[0004] In the above patent document, the filter groups are arranged in series, and the water flows through several filters in the filter group in turn.

DETAILED DESCRIPTION

[0033] 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.

[0034] Reference Figures 1 to 14As shown: a drainage pipeline with a self-cleaning function, including a three-way diversion pipeline 1, two filtering structures 2, two cleaning structures 3 and an adaptive water flow driving structure 4; the three-way diversion pipeline 1 includes a vertical water inlet pipe 11 and a horizontal water outlet pipe 12, the water inlet pipe 11 is connected to the middle of the water blowing pipe, and sewage outlets 121 are provided at the bottom of both ends of the water outlet pipe 12, and the two sewage outlets 121 are connected by setting a sewage pipe 13, and the sewage pipe 13 is used to temporarily store debris; the two filtering structures 2 are respectively set at two sides of the two sewage outlets 121 away from each other, the filtering structure 2 includes a filtering assembly 21, water passes through the sewage outlet 121 and then passes through the filtering assembly 21, the filtering assembly 21 includes an installation frame 211 and a filter net 212, the filter net 212 is arranged in the installation frame 211, and the lower end of the installation frame 211 is connected to the water outlet pipe 1 2 is hinged on the inner bottom surface; two cleaning structures 3 are arranged between the two sewage outlets 121, the cleaning structure 3 includes a cleaning brush 31, the cleaning brush 31 abuts against the inner wall of the outlet pipe 12, and a transmission vertical shaft 32 is arranged in the middle of the cleaning brush 31; the adaptive water flow driving structure 4 includes a water flow driving component 41 arranged in the water inlet pipe 11, the water flow driving component 41 includes a main rotating shaft 411, and a plurality of unpowered fan blades 412 are sleeved on the main rotating shaft 411. A conical driving disk 42 is arranged at the lower end of the main rotating shaft 411. The conical driving disk 42 moves up and down along the main rotating shaft 411 with the size of the water flow. The outer cover of the conical driving disk 42 is provided with a rectangular frame 43, and transmission structures 44 are arranged at both ends of the rectangular frame 43. The transmission structure 44 transmits the force generated when the conical driving disk 42 rotates to the filter component 21 and the cleaning brush 31.

[0035] A three-way diversion pipe 1 equipped with two filtering structures 2, two cleaning structures 3 and an adaptive water flow driving structure 4 is connected to the drainage pipeline line, and the water inlet pipe 11 is kept in a vertical state. Water flows in from the water inlet pipe 11 and is diverted into two water flows from the water outlet pipe 12. As the water flows through the water inlet pipe 11, the rotation of the unpowered fan blades 412 drives the main shaft 411 and the conical driving disk 42 to rotate, thereby driving the transmission structure 44 to produce reciprocating linear motion. This motion enables the filter assembly 21 to swing periodically, effectively removing debris attached to the filter screen 212, reducing blockage and maintenance costs. At the same time, the movement of the transmission structure 44 drives the cleaning brush 31 to clean the water outlet pipe 12. The mechanical structure 3 realizes automatic cleaning inside the pipeline. When the flow rate of water entering the water inlet pipe 11 is large, the downward force exerted by the water flow on the plurality of unpowered blades 412 is large, so the water flow pushes the main shaft 411 to move downward, and the main shaft 411 drives the conical drive disk 42 to move downward. The rotation diameter of the contact part between the conical drive disk 42 and the transmission structure 44 is increased, so that the transmission structure 44 can move within a wider range, and the filter component 21 can therefore swing within a wider swing range, so that the debris on the filter component 21 is easier to fall off, so that the filter component 21 can filter a large flow of water, thereby realizing automatic cleaning of the inside of the pipeline according to the amount of water without the need for external energy input, and effectively preventing blockage.

[0036] Reference Figure 5 and Figure 6 As shown: the conical driving disk 42 includes a conical frame 421, which is connected to the lower end of the main rotating shaft 411, and a plurality of rollers 422 are arranged in a circular array around the conical frame 421, and the angles between the plurality of rollers 422 and the main rotating shaft 411 are the same; the transmission structure 44 includes a transmission plate 441, which is arranged on one side of the conical frame 421, and transmission rods 442 are fixedly arranged at both ends of the transmission plate 441, one end of the transmission rod 442 passes through the rectangular frame 43 and is slidably connected to the rectangular frame 43, a third spring 4421 is sleeved on the transmission rod 442, and the two ends of the third spring 4421 are respectively connected to the transmission plate 441 and the rectangular frame 43, a connecting rod 443 is arranged at one end of the transmission rod 442, the middle part of the connecting rod 443 is connected to the two transmission rods 442, and the two ends of the connecting rod 443 are connected to the two sides of the filter assembly 21.

[0037] The main rotating shaft 411 drives the conical frame 421 to rotate, and the conical frame 421 drives several rollers 422 to rotate around the axis of the main rotating shaft 411. When the conical frame 421 drives a roller 422 to rotate toward the transmission plate 441, the vertical distance between the roller 422 and the main rotating shaft 411 increases, and the roller 422 applies a thrust to the transmission plate 441. The transmission plate 441 applies a thrust to the filter assembly 21 through two transmission rods 442 and the connecting rod 443. The thrust causes the filter assembly 21 to rotate around the connection between it and the water outlet pipe 12, and the angle between the filter assembly 21 and the water outlet pipe 12 decreases. When the roller 422 is located between the transmission plate 441 and the main rotating shaft 411, and the roller 422, the transmission plate 441 and the main rotating shaft 411 are in the same line, the distance between the transmission plate 441 and the main rotating shaft 411 is the longest, and the transmission plate 441 squeezes the third spring 4421, and then the conical frame 421 continues to drive the roller 422 to rotate around the axis of the main rotating shaft 411, and the vertical distance between the roller 422 and the main rotating shaft 411 gradually decreases. The third spring 4421 releases elastic potential energy to push the transmission plate 441 toward the main rotating shaft 411. The transmission plate 441 drives the filter assembly 21 to rotate through two connecting rods 443, so that the angle between the filter assembly 21 and the water outlet pipe 12 increases. When the two transmission plates 441 contact the two rollers 422 at the same time, the transmission plate 441 cannot continue to move toward the main rotating shaft 411. At this time, the distance between the transmission plate 441 and the main rotating shaft 411 is the shortest. Through the contact and separation of the roller 422 and the transmission plate 441, and the elastic action of the third spring 4421, the filter assembly 21 is swung within a certain range, effectively capturing and removing impurities in the water and reducing the risk of clogging of the filter assembly 21.

[0038] Reference Figure 6 and Figure 7 As shown, a slope 4411 is provided on one side of the transmission plate 441 facing the conical driving disk 42 , the inclination angle of the slope 4411 is the same as the angle between the roller 422 and the main shaft 411 , and an inner concave surface 4412 is provided in the middle of the slope 4411 .

[0039] By providing an inclined surface 4411 on the transmission plate 441 with the same angle as that between the roller 422 and the main shaft 411, when the roller 422 rotates and contacts the transmission plate 441, the roller 422 is tangent to the inclined surface 4411 of the transmission plate 441, rather than only contacting one edge of the transmission plate 441. This significantly increases the contact area between the roller 422 and the transmission plate 441, disperses the local force on the surface of the roller 422, effectively reduces the wear of the outer wall of the roller 422, and extends the service life of the roller 422. In the process of contact and separation between the roller 422 and the transmission plate 441, the transmission plate 441 is driven to reciprocate at a stable frequency, and the transmission plate 441 is driven to reciprocate at a stable frequency. The movable plate 441 drives the filter assembly 21 to swing, which helps to shake off some debris attached to the filter assembly 21 through shaking. However, for some stubbornly attached debris, a simple stable frequency swing may not be sufficient to completely remove it. Therefore, an inner concave surface 4412 is opened in the middle of the transmission plate 441, so that the roller 422 suddenly loses contact when it rotates to the middle of the transmission plate 441, and the thrust applied to the transmission plate 441 by the third spring 4421 is used to achieve sudden shaking. This sudden and larger-amplitude shaking can more effectively shake off stubbornly attached debris from the filter assembly 21, thereby improving the filtering efficiency and cleaning effect.

[0040] Reference Figure 5 and Figure 8 As shown: the water flow driving component 41 also includes a flow gathering component 413 and a lifting component 414; the flow gathering component 413 is covered on the outside of the main rotating shaft 411, and the flow gathering component 413 is used to gather the water flow into the rotation range of the unpowered fan blades 412. The flow gathering component 413 includes a hanging frame 4131 and a flow gathering barrel 4132. The hanging frame 4131 is connected to the water inlet pipe 11, and the upper end of the main rotating shaft 411 is connected to the hanging frame 4131. The flow gathering barrel 4132 is covered on a plurality of unpowered fan blades 4 12 outside; the lifting component 414 is arranged at the upper end of the main rotating shaft 411, and the lifting component 414 applies different sizes of downward force to the main rotating shaft 411 according to the size of the water flow. The lifting component 414 includes a second water baffle 4141 and a second spring 4142, the second water baffle 4141 is connected to the main rotating shaft 411, and the second spring 4142 is sleeved on the main rotating shaft 411, and the two ends of the second spring 4142 are respectively abutted against the second water baffle 4141 and the hanging frame 4131.

[0041] The flow-gathering component 413 effectively solves the problem of water flow dispersion caused by the shape or size of the water inlet pipe 11. The water flow is gathered into the rotation range of the unpowered fan blade 412 through the flow-gathering barrel 4132, ensuring that all water flowing through the water inlet pipe 11 can exert a force on the fan blade, thereby improving the utilization efficiency of the water flow and enhancing the power source for the rotation of the unpowered fan blade 412. When the water flows through the unpowered fan blade 412, it will exert a downward force on the unpowered fan blade 412, but the force will be decomposed into the power for the rotation of the unpowered fan blade 412, so that the ability of the force to drive the main shaft 411 to move downward is relatively weak. By setting the second water baffle 4141 and the second spring 4142, the design of the second water baffle 4141 increases the water flow impact area, ensuring that the water flow produces a stable and concentrated downward force on the main shaft 411, and the second spring 4142 plays a buffering and regulating role, thereby realizing automatic adjustment of the position of the main shaft 411 according to changes in the water flow.

[0042] Reference Figure 5 and Fig. 9 As shown: the adaptive water flow driving structure 4 also includes two linked rotating structures 45, the two linked rotating structures 45 correspond to the two cleaning structures 3 respectively, the linked rotating structure 45 includes a driven gear 451, two intermittent transmission components 452 and a reciprocating driving component 453; the driven gear 451 is connected to the transmission vertical shaft 32; the two intermittent transmission components 452 are respectively arranged on the two transmission rods 442, and the intermittent transmission components 452 can move along the diameter direction of the transmission vertical shaft 32, and the intermittent transmission components 452 are used to drive the driven gear 451 to rotate; the reciprocating driving component 453 is arranged outside the water outlet pipe 12, and the reciprocating driving component 453 Used to drive two intermittent transmission components 452 to alternately contact with the driven gear 451, the reciprocating drive component 453 includes a moving plate 4531, the moving plate 4531 is arranged above the water outlet pipe 12, and the moving plate 4531 can move in a direction perpendicular to the transmission rod 442, and both ends of the moving plate 4531 are provided with hanging plates 4532, one end of the hanging plate 4532 is connected to the moving plate 4531, and the other end of the hanging plate 4532 is provided with a transmission horizontal shaft 4533, one end of the transmission horizontal shaft 4533 is connected to the hanging plate 4532, and the other end of the transmission horizontal shaft 4533 passes through the water outlet pipe 12 and is connected to the intermittent transmission component 452.

[0043] The conventional cleaning structure 3 may be limited by the moving range of the transmission rod 442, resulting in a limited cleaning area covered by the cleaning brush 31. By setting a linkage rotating structure 45, when the transmission rod 442 moves in a direction away from the main rotating shaft 411, the moving plate 4531 moves toward one side of the three-way diversion pipe 1, and one of the two hanging plates 4532 is close to the three-way diversion pipe 1 and the other is away from the three-way diversion pipe 1. The two hanging plates 4532 respectively drive the two intermittent transmission components 452 to contact and separate from the driven gear 451, and the intermittent transmission component 452 drives the driven gear 451 to rotate counterclockwise. The intermittent transmission component 452 moves to the side of the three-way diversion pipe 1. After the driven gear 451 is separated, the moving plate 4531 moves toward the other side of the three-way diversion pipe 1, and the contact state between the two intermittent transmission components 452 and the driven gear 451 changes. During the process of the transmission rod 442 resetting toward the main shaft 411, the intermittent transmission component 452 continues to drive the driven gear 451 to rotate counterclockwise, so that the transmission vertical shaft 32 continues to rotate in one direction, and the transmission vertical shaft 32 drives the cleaning brush 31 to rotate. During the rotation process, the cleaning brush 31 will push the debris within its coverage range into the sewage outlet 121, thereby realizing the continuous pushing of debris to the sewage outlet 121, which greatly improves the cleaning efficiency.

[0044] Reference Fig. 9 and Fig.10 As shown: the intermittent transmission assembly 452 includes a transmission rack 4521, a transmission block 4522, a fourth guide rod 4523 and a fourth slider 4524; the transmission rack 4521 is meshed with the driven gear 451; the transmission block 4522 is slidably set on the transmission rod 442, and the transmission block 4522 can move along the diameter direction of the transmission rod 442, and the transmission rack 4521 is installed on one side of the transmission block 4522; the fourth guide rod 4523 is set on the other side of the transmission block 4522, and the fourth guide rod 4523 is set parallel to the transmission rod 442; the fourth slider 4524 is slidably set on the fourth guide rod 4523, and the fourth slider 4524 is connected to the transmission cross shaft 4533.

[0045] Through the meshing of the transmission rack 4521 and the driven gear 451, and the sliding of the transmission block 4522 on the transmission rod 442, precise control of the contact and separation of the transmission rack 4521 and the driven gear 451 is achieved. This control mechanism enables the intermittent transmission assembly 452 to accurately contact the driven gear 451 when needed, transmit power and drive the driven gear 451 to rotate, and quickly separate when not needed, avoiding unnecessary friction and wear.

[0046] Reference Fig.11 and Fig.12As shown: the filtering structure 2 also includes two swing connection structures 22 and a cleaning plate 23; the two swing connection structures 22 are respectively arranged on both sides of the filtering component 21, and the swing connection structure 22 includes a first guide rod 221, the first guide rod 221 is parallel to the filtering component 21, and a first slider 222 is slidably arranged on the first guide rod 221, and the first slider 222 is connected to the connecting rod 443; the two ends of the cleaning plate 23 are respectively connected to the two first sliders 222, and the cleaning plate 23 is arranged parallel to the filtering component 21, and bristles 231 are arranged on the side of the cleaning plate 23 facing the filtering component 21, and a plurality of water-permeable strip grooves 232 are opened on the cleaning plate 23 at equal intervals.

[0047] During the filtering process, some stubborn debris may accumulate on the filter screen 212, which is difficult to be completely removed by simple shaking or water flushing. By setting a cleaning plate 23, a plurality of water-permeable strip grooves 232 are provided on the cleaning plate 23 so that the water can flow smoothly to the filter screen 212, and some stubborn debris on the filter screen 212 is difficult to fall off during the shaking process. When the connecting rod 443 applies a thrust to the mounting frame 211 causing the mounting frame 211 to tilt, the cleaning plate 23 can move back and forth along the filter screen 212, and the bristles 231 are in direct contact with the surface of the filter screen 212, effectively removing the stubborn debris attached to the screen, thereby keeping the filter screen 212 clean and unobstructed, and extending the service life of the filter screen 212.

[0048] Reference Figure 1 , Fig.11 , Fig.13 and Fig.14As shown: the filtering structure 2 also includes a lifting structure 24, which is arranged at the upper end of the filtering assembly 21, and the lifting structure 24 includes a sealing cover 241, a lifting structure 242 and a sliding structure 243; the sealing cover 241 is arranged above the filtering assembly 21; the lifting structure 242 is arranged at the upper end of the filtering assembly 21, and the lifting structure 242 includes a first connecting plate 2421 and a second connecting plate 2422 parallel to each other, the first connecting plate 2421 is connected to the upper end of the mounting frame 211, the first connecting plate 2421 is provided with a second guide rod 2423, and the second guide rod 2423 is slidably provided with two second sliders 2424, the first connecting plate 2421 and the second connecting plate 2422 are connected to the upper end of the mounting frame 211, and the second connecting plate 2421 is provided with a second guide rod 2423, and the second guide rod 2423 is slidably provided with two second sliders 2424, and the first connecting plate 2421 and the second connecting plate 2422 are connected to the first connecting plate 2421 and the second connecting plate 2422. Two lifting plates 2425 are cross-arranged between the plates 2422, and the two ends of the lifting plates 2425 are respectively connected to the second connecting plate 2422 and the second slider 2424; the sliding structure 243 is arranged inside the sealing cover 241, and the upper end of the lifting structure 242 is connected to the sliding structure 243, and the sliding structure 243 includes a third guide rod 2431, and the two ends of the third guide rod 2431 are connected to the sealing cover 241, and the third guide rod 2431 is parallel to the transmission rod 442, and a third slider 2432 is slidably arranged on the third guide rod 2431, and the third slider 2432 is connected to the second connecting plate 2422, and a first spring 2433 is also sleeved on the third guide rod 2431.

[0049] The water flow will exert a force on the filter assembly 21 away from the main shaft 411, and the filter assembly 21 will therefore drive the transmission rod 442 to move. If the force exerted by the water flow speed on the filter assembly 21 is large, the rotation angle of the filter assembly 21 around the hinge between it and the water outlet pipe 12 is large, and the filter assembly 21 will drive the transmission plate 441 to separate from the conical drive disk 42. The conical drive disk 42 cannot drive the filter assembly 21 to swing through the transmission structure 44. By setting the lifting structure 242 and the sliding structure 243, when the filter assembly 21 is tilted, the second connecting plate 2422 moves at the same height under the action of the third slider 2432 and the third guide rod 2431, and the first connecting plate 2421 moves away from the second connecting plate 2422 under the drive of the filter assembly 21. The two lifting plates 2425 always maintain the connection between the first connecting plate 2421 and the second connecting plate 2422, so that the moving range of the upper end of the filter assembly 21 is limited by the lifting structure 242 and the sliding structure 243, thereby limiting the movement of the filter assembly 21 within an effective range.

[0050] Reference Fig.13 As shown, the hoisting structure 24 also includes a first water baffle 244 , which is disposed on one side of the lifting structure 242 .

[0051] When the filter assembly 21 is tilted, the height of the upper end of the filter assembly 21 will be reduced, and the water flow may flow through the upper end of the filter assembly 21, resulting in some debris in the water flow not being intercepted. By setting the first water baffle 244, the first water baffle 244 is connected to the second connecting plate 2422. Since the height of the second connecting plate 2422 remains unchanged, the first water baffle 244 can always block the water flow at the same height, so the water flow cannot flow through the upper end of the filter assembly 21, thereby preventing some debris from flowing out of the three-way diversion pipe 1.

[0052] A drainage method for a drainage pipe with a self-cleaning function comprises the following steps: S1, connect the three-way diversion pipe 1 equipped with two filtering structures 2, two cleaning structures 3 and an adaptive water flow driving structure 4 to the drainage pipeline line, and keep the water inlet pipe 11 in a vertical state; S2, water flows in from the water inlet pipe 11, and when the water flows through the plurality of unpowered blades 412, the plurality of unpowered blades 412 rotate to drive the main shaft 411 to rotate, and the main shaft 411 drives the conical drive disk 42 to rotate; S3, during the rotation process, the conical drive disc 42 drives the two filter structures 2 and the two cleaning structures 3 at both ends of the water outlet pipe 12 to work simultaneously through the two transmission structures 44, the filter structure 2 swings within its swing range, and the cleaning structure 3 cleans the debris in the water outlet pipe 12 into the sewage pipe 13; S4, when the flow rate of water flow is large, the water flow pushes the main shaft 411 to move downward along its axial direction, and the main shaft 411 drives the conical drive disk 42 to move downward, the diameter of the contact part between the conical drive disk 42 and the transmission structure 44 becomes larger, and the moving path of the transmission structure 44 driven by the conical drive disk 42 increases, so the swing range of the filter structure 2 increases, and the shaking amplitude of the filter structure 2 increases; S5, the linkage rotation structure 45 converts the linear motion of the transmission structure 44 into the rotational motion of the transmission vertical shaft 32, so that the cleaning brush 31 rotates to clean the water outlet pipe 12.

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.
