Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, in particular to a semi-automatic controlled pipeline cleaning device. Background Art

[0002] The main functions of pipes are to drain and transport water. When using pipes to transport drinking water, since drinking water is filtered, it is generally not prone to blockage. However, when using pipes to drain sewage, the discharged sewage may contain debris, which can easily get stuck in the pipe, especially at bends. This can cause pipe blockage, so regular cleaning is necessary. In order to enable pipes to have an automatic cleaning function, the prior art generally installs a dredging mechanism on the pipe. The following are relevant technical documents retrieved by the inventor.

[0003] The Chinese utility model patent application number is 202022472952.7. It is a kind of anti-clogging sewage elbow. Six filter plates are installed in the elbow for rotation. When the sewage is discharged, the filter plates are driven to rotate and stir in the elbow to prevent clogging.

To this end, the inventor has conducted useful explorations and attempts and found a solution to the above-mentioned problem. The technical solution to be introduced below was produced in this context. Summary of the Invention

[0011] a transmission mechanism connected between the piston plate and the threaded rod;

[0012] The dragging mechanism includes a rotating rod, one end of which is fixed with a shaft, the shaft is rotatably connected to the upper end of the transverse dredging block, and a torsion spring is connected between the shaft and the transverse dredging block, and a draw hook is fixed to one side of the upper end of the rotating rod;

[0013] The dredging particle carrier plate is slidably mounted on the inner upper end of the cylinder, and dredging particles are placed on the surface of the dredging particle carrier plate.

[0014] The transmission mechanism includes a return spring connected between the piston plate and the circular tube, a first pulley and a second pulley rotatably installed in the circular tube, a belt connected between the first pulley and the second pulley, the first pulley is fixed with a gear, the second pulley is fixed with a first bevel gear, the lower end of the piston plate is fixed with a rack, the gear is meshed with the rack, a slide groove is embedded in the bottom of the connecting pipe, the bottom of the horizontal dredging block and the pushing block are slidably connected to the slide groove, one end of the threaded rod is fixed with a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0015] A manual operating rod is fixed to the upper end of the piston plate, and the upper end of the manual operating rod passes through the upper end of the round tube.

[0016] The diameter of the first pulley is greater than the diameter of the second pulley, and the diameter of the first bevel gear is greater than the diameter of the second bevel gear.

[0017] The dredging particle carrier plate is penetrated by a through hole, and the manual operating rod passes through the through hole.

[0018] The surface of the dredging particle carrier plate and the inner lower end of the overflow pipe are both inclined downward toward the direction of the elbow.

[0019] Guide blocks are fixed on both sides of the piston plate, and guide grooves are provided on both sides of the inner wall of the circular tube. The guide blocks and the guide grooves are slidably connected.

[0020] An arc-shaped accommodating groove is embedded in the inner wall of the bent pipe.

[0021] The pushing block is fixed with a bearing, and the rotating shaft is rotatably connected to the pushing block through the bearing.

[0022] The beneficial effects of the present invention are:

[0023] 1. When the elbow is clogged, the water in the elbow enters the round pipe through the overflow pipe, squeezing the piston plate downward. Under the transmission action of the transmission mechanism, the threaded rod is driven to rotate, and the rotation of the threaded rod drives the push block to slide. When the push block slides, the push spring pushes the transverse dredging block outward, so that the transverse dredging block enters the transverse section of the elbow, pushing the blockage to move. When the transverse dredging block encounters greater resistance and is difficult to move forward, the push spring is compressed, and the push block continues to move, so that the stirring cable follows the pushing block to move forward and penetrate into the blockage. The threaded rod and the stirring cable are connected by the rotating shaft, so that the rotation of the threaded rod drives the stirring cable to rotate, so that after the stirring cable penetrates the blockage, it stirs the blockage and quickly removes the blockage.

[0024] 2. In order to improve the dredging effect of the transverse dredging block, the present invention provides a dragging mechanism on the transverse dredging block. When the transverse dredging block slides horizontally toward the transverse section of the elbow, it drives the dragging mechanism to slide horizontally. The hook at the head of the rotating rod hooks the obstruction during the transverse movement. As the transverse dredging block moves, the hook pulls the obstruction laterally. Moreover, because the length of the rotating rod is fixed, the hook also pulls the obstruction downward when the transverse dredging block moves laterally, thereby achieving a better dredging effect.

[0025] 3. The present invention has a dredging particle carrier slidably installed on the upper end of the inner part of the cylinder. When the elbow is blocked, the water entering the elbow cannot be discharged through the transverse section of the elbow, so it gets deeper and deeper in the longitudinal section of the elbow and then enters the circular pipe. After the water enters the circular pipe, the dredging particle carrier floats up, driving some undissolved dredging particles to float up. When the dredging particle carrier floats to the position of the overflow pipe, the dredging particles are not blocked by any obstacles on the side close to the overflow pipe, and flow downward along the slope and fall on the blockage in the elbow, partially dissolving the blockage and facilitating dredging.

[0026] 4. A manual operating rod is fixed to the upper end of the piston plate of the present invention, and the upper end of the manual operating rod passes through the upper end of a round tube. When the elbow is blocked, the piston plate slides downward under the action of the water pressure in the elbow, thereby driving the transverse dredging block to dredge. After dredging, it can automatically reset upward under the elastic force of the reset spring. When the personnel observes that the manual operating rod does not reset after moving downward, it is obvious that the transverse dredging block is stuck in the blockage and is not dredged well. Therefore, at this time, the personnel can drive the piston plate to move up and down by pushing and pulling the manual operating rod up and down, and drive the transverse dredging block to slide back and forth in the transverse section of the elbow through the transmission mechanism, and pull the blockage in the longitudinal section of the elbow downward through the dragging mechanism to force dredging.

[0027] 5. The power structure for driving the transverse dredging block of the present invention is mainly arranged in the circular pipe, separated from the curved pipe, and will not occupy the space in the curved pipe. The transverse dredging block is hidden in the connecting pipe when the curved pipe is not blocked, and the dragging mechanism is hidden in the arc-shaped receiving groove when the curved pipe is not blocked, so as to ensure that the inner wall of the curved pipe is as smooth and flat as possible, and reduce the interference with the flow of debris during drainage. The design of the hidden dredging mechanism of the pipeline cleaning device of the present invention is a significant improvement compared with the dredging mechanism of traditional pipelines.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figure 1-Figure 5 As shown, the present invention provides a semi-automatic controlled cleaning device for a pipeline, comprising a bend 1 and a circular pipe 2 vertically arranged on one side of the bend 1, an overflow pipe 3 is connected between the upper end side of the circular pipe 2 and the longitudinal section 101 of the bend 1, when the bend 1 is blocked, the water entering the bend 1 will enter the circular pipe 2 through the overflow pipe 3, a horizontally arranged connecting pipe 4 is connected between the lower end side of the circular pipe 2 and the transverse section 102 of the bend 1, and a through hole 5 is provided at the connection portion between the connecting pipe 4 and the transverse section 102 of the bend 1. It can be understood that the bend 1, the circular pipe 2, the overflow pipe 3 and the connecting pipe 4 are of an integrally formed design. When in use, the longitudinal section 101 and the transverse section 102 of the bend 1 are connected to the drainage pipe through a flange, and further comprising:

[0036] A piston plate 6 slides vertically within circular tube 2. Guide blocks 28 are fixed to each side of piston plate 6. Guide grooves 29 are provided on the inner wall of circular tube 2. Guide blocks 28 and grooves 29 are slidably connected. Sewage from the drainage pipe flows through longitudinal section 101 into elbow 2. If elbow 2 becomes clogged, water entering elbow 2 flows through overflow pipe 3 into circular tube 2, forcing piston plate 6 downward, guided by guide blocks 28 and grooves 29.

[0037] The transverse dredging mechanism includes a transverse dredging block 7 ( Figure 3As shown), when the transverse dredging block 7 slides transversely, it can push the obstruction in the transverse section 102 of the elbow 1 in the horizontal direction. Specifically, the transverse dredging block 7 is penetrated by a circular hole 70, and a stirring steel cable 71 is provided in the circular hole 70 for rotation. The stirring steel cable 71 can slide along the length direction of the through hole 70, and is inserted into the obstruction in the transverse section 102 of the elbow 1 while sliding, and then the obstruction is stirred by rotation. A pushing block 72 is provided for sliding at the bottom of the connecting pipe 4. The pushing block 72 is used to push the transverse dredging block 7 to move horizontally. The pushing block 72 is connected to the transverse dredging block 7. A push spring 73 is connected between the dredging blocks 7, and a threaded rod 74 is provided at the bottom of the connecting pipe 4 for rotation. The head of the threaded rod 74 is threadedly connected to the rear end of the pushing block 72. When the threaded rod 74 rotates, the pushing block 72 slides, and the pushing spring 73 is squeezed to push the transverse dredging block 7 to move. The blockage in the transverse section 102 is pushed through the transverse dredging block 7, and the rear end of the stirring cable 71 is fixed with a rotating shaft 75, and the pushing block 72 is fixed with a bearing 24. The rotating shaft 75 and the pushing block 72 are connected through the bearing 24 to realize the rotation of the rotating shaft 75 and the pushing block 72 When the cam 72 is in the closed position, the spring 73 is pressed against the locking cam 74 to lock the cam 72 in the closed position, and the cam 72 is in the closed position to lock the cam 72 in the closed position. When the force can no longer move forward, the pushing spring 73 continues to compress, and the pushing block 72 continues to move, so that the stirring cable 71 follows the pushing block 72 to move forward, passes through the round hole 70 and penetrates into the blockage, and the threaded rod 74 is connected to the stirring cable 71 through the rotating shaft 75, so that the rotation of the threaded rod 74 drives the stirring cable 71 to rotate, so that after the stirring cable 74 penetrates the blockage, it stirs the blockage to loosen the blockage. The loosened blockage moves to the right of the horizontal section 102 under the pressure of the horizontal dredging block 7, thereby quickly removing the blockage.

[0038] The transmission mechanism 8 is connected between the piston plate 6 and the threaded rod 74. Through the setting of the transmission mechanism 8, when the piston plate 6 moves downward, the threaded rod 74 is driven to rotate, so that when the horizontal dredging block 7 slides to the left to push the blockage, the stirring cable 71 penetrates the blockage and stirs it.

[0039] Furthermore, in order to improve the dredging effect of the transverse dredging block 7, a dragging mechanism 9 is provided on the transverse dredging block 7. The dragging mechanism 9 includes a rotating rod 10. A shaft 11 is fixed at one end of the rotating rod 10. The shaft 11 is rotatably connected to the upper end of the transverse dredging block 7. A torsion spring 12 is connected between the shaft 11 and the transverse dredging block 7. A hook 13 is fixed to one side of the upper end of the rotating rod 10. When the transverse dredging block 7 slides horizontally toward the transverse section of the elbow 2, it drives the dragging mechanism 9 to slide horizontally. The hook 13 at the head of the rotating rod 10 hooks the blockage during the transverse movement. As the transverse dredging block 7 moves, the hook 13 pulls the blockage laterally to the right. Because the length of the rotating rod 10 is fixed, when the transverse dredging block 7 moves laterally, the hook 13 will also pull the blockage downward, loosening the blockage in the longitudinal section 101 and achieving a better dredging effect.

[0040] Furthermore, a dredging particle carrier 14 is slidably installed at the upper end of the interior of the cylinder 2, and the dredging particle carrier 14 can float in the water. Dredging particles 15 are placed on the surface of the dredging particle carrier 14, and the surface of the dredging particle carrier 14 and the lower end of the interior of the overflow pipe 3 are both inclined downwardly toward the direction of the elbow 1. The dredging particles 15 are of prior art and can react chemically with the blockage after being added to the water to dissolve the blockage, thereby unblocking the pipe. When the elbow 2 is blocked, the water entering the elbow 2 cannot be discharged through the transverse section 102 of the elbow 2, so it becomes deeper and deeper in the longitudinal section 101 of the elbow 2, and then enters the circular pipe 2. After the water enters the circular pipe 2, the dredging particle carrier 14 floats up, driving some of the dredging particles 15 that have not yet dissolved to float up. When the dredging particle carrier 14 floats to the position of the overflow pipe 3, the dredging particles 15 are close to the overflow pipe 3 without any obstacles, and flow downward along the slope and fall on the blockage in the elbow 1, partially dissolving the blockage, which is conducive to unblocking.

[0041] In order to facilitate the later addition of the dredging particles 15, a threaded cover 30 is installed on the upper end of the cylinder 2. The threaded cover 30 is threadedly connected to the upper end of the circular tube 2. The dredging particles can be added by removing the threaded cover 30.

[0042] It should be noted that the dredging particles 15 will not corrode plastic pipes. The main ingredients of the dredging particles 15 are caustic soda and alkali, which generate high temperatures to remove oil stains. This is not suitable for hoses and may corrode them. It is also corrosive to aluminum pipes. However, it has no problem corroding plastic pipes, steel pipes, or iron pipes, and can be used with confidence.

[0043] Specifically, the transmission mechanism includes a return spring 16 connected between the piston plate 6 and the circular tube 2, a first pulley 17 and a second pulley 18 rotatably installed in the circular tube 2, a belt 19 is connected between the first pulley 17 and the second pulley 18, the first pulley 17 is fixed with a gear 20, the second pulley 18 is fixed with a first bevel gear 21, the lower end of the piston plate 6 is fixed with a rack 22, the gear 20 is meshed with the rack 22, the bottom of the connecting pipe 4 is embedded with a slide groove 23, the bottom of the horizontal dredging block 7 and the pushing block 72 are slidably connected to the slide groove 23, one end of the threaded rod 74 is fixed with a second bevel gear 25, and the first bevel gear 21 is meshed with the second bevel gear 25. When the piston plate 6 moves downward, the gear 20 is driven to rotate through the rack 22. When the gear 20 rotates, it drives the first pulley 17 to rotate. The first pulley 17 drives the second pulley 18 to rotate. The second pulley 18 drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the second bevel gear 25 to rotate. The second bevel gear 25 drives the threaded rod 74 to rotate. When the threaded rod 74 rotates, it drives the pushing block 72 to move, so that the transverse dredging block 7 is transversely dredged.

[0044] In addition, a manual operating rod 26 is fixed to the upper end of the piston plate 6, and a sliding sealing ring 27 is fixedly installed on the threaded cover 30. The upper end of the manual operating rod 26 passes through the sliding sealing ring 27. When adding the dredging particles 15, the threaded cover 30 is rotated upward to add the dredging particles 15 into the round tube 2 through the gap at the lower end of the threaded cover 30. The pipeline cleaning device of the present invention can also be manually controlled by the setting of the manual operating rod 26. When the elbow 1 is blocked, the piston plate 6 slides downward under the action of the water pressure in the elbow 1, thereby driving the lateral The dredging block 7 is dredged, and after dredging, it can automatically reset upward under the elastic force of the reset spring 16. When the personnel observes that the manual operating lever 26 does not reset after moving downward, it is obvious that the horizontal dredging block 7 is stuck in the blockage and is not dredged well. Therefore, at this time, the personnel can drive the piston plate 6 up and down by pushing and pulling the manual operating lever 26 up and down, and drive the horizontal dredging block 7 to slide back and forth in the horizontal section 102 of the elbow 1 through the transmission mechanism, and pull the blockage in the longitudinal section 101 of the elbow 1 downward through the dragging mechanism 9 to force dredging.

[0045] The diameter of the first pulley 17 is greater than that of the second pulley 18 , and the diameter of the first bevel gear 21 is greater than that of the second bevel gear 25 , thereby increasing the transmission ratio and making the threaded rod 24 rotate faster.

[0046] Specifically, the dredging particle carrier plate 14 is penetrated by a through hole, and the manual operating rod 26 passes through the through hole.

[0047] It is worth mentioning that the inner wall of the curved pipe 1 is embedded with an arc-shaped receiving groove 29, and the head of the transverse dredging block 7 is a curved surface structure. When no blockage occurs, the transverse dredging block 7 is hidden in the connecting pipe 4, and its head transitions to the inner wall of the curved pipe 1 in an arc shape, while the dragging mechanism is hidden in the arc-shaped receiving groove 29, ensuring that the inner wall of the curved pipe 1 is as smooth and flat as possible, reducing interference with the flow of debris during drainage.

[0048] Working principle: When the elbow 2 of the present invention is clogged, the water entering the elbow 2 enters the circular pipe 2 through the overflow pipe 3, squeezing the piston plate 6 downward, and under the transmission action of the transmission mechanism 8, the threaded rod 74 is driven to rotate, and the rotation of the threaded rod 74 drives the pushing block 72 to slide. When the pushing block 72 slides, it pushes the transverse dredging block 7 outward through the pushing spring 73, so that the transverse dredging block 7 enters the transverse section of the elbow 1, pushing the blockage to move. When the transverse dredging block 7 encounters greater resistance and is difficult to move forward, the pushing spring 73 continues to be compressed, and the pushing block 72 continues to move, so that the stirring cable 71 follows the pushing block 72 to move forward and penetrate into the blockage, and the threaded rod 74 and the stirring cable 71 pass through The rotating shaft 75 remains connected, so that the threaded rod 74 rotates and drives the stirring cable 71 to rotate, so that after the stirring cable 74 penetrates the blockage, it stirs the blockage and quickly removes the blockage; the transverse dredging block 7 of the present invention is provided with a dragging mechanism 9, and when the transverse dredging block 7 slides horizontally toward the transverse section 102 of the elbow 2, it drives the dragging mechanism 9 to slide horizontally, and the hook 13 at the head of the rotating rod 10 hooks the blockage when it moves horizontally. As the transverse dredging block 7 moves, the hook 13 pulls the blockage horizontally, and because the length of the rotating rod 10 is fixed, the hook 13 will also pull the blockage downward when it moves horizontally with the transverse dredging block 7, so that the dredging effect is better; the present invention is provided with a dragging mechanism 9 on the transverse dredging block 7, and when the transverse dredging block 7 slides horizontally, the dragging mechanism 9 will slide horizontally, and the hook 13 at the head of the rotating rod 10 will hook the blockage when it moves horizontally. A dredging particle carrier plate 14 is slidably installed. When the elbow 2 is blocked, the water entering the elbow 2 cannot be discharged through the transverse section 102 of the elbow 2, so that the water goes deeper and deeper in the longitudinal section 101 of the elbow 2, and then enters the circular pipe 2. After the water enters the circular pipe 2, the dredging particle carrier plate 14 floats up, driving some of the dredging particles 15 that have not yet dissolved to float up. When the dredging particle carrier plate 14 floats to the position of the overflow pipe 3, the dredging particles 15 are close to the overflow pipe 3 on one side without any obstacles. They flow downward along the slope and fall on the blockage in the elbow 1, partially dissolving the blockage, which is conducive to dredging. The upper end of the piston plate 6 of the present invention is fixed with a manual operating rod 26, and the upper end of the manual operating rod 26 is penetrated by a At the upper end of the circular tube 2, when the elbow 1 is blocked, the piston plate 6 slides downward under the action of the water pressure in the elbow 1, thereby driving the transverse dredging block 7 to dredge. After dredging, it can automatically reset upward under the elastic force of the reset spring 16. When the personnel observes that the manual operating lever 26 does not reset after moving downward, it is obvious that the transverse dredging block 7 is stuck in the blockage and is not dredged well. Therefore, at this time, the personnel can drive the piston plate 6 to move up and down by pushing and pulling the manual operating lever 26 up and down, and drive the transverse dredging block 7 to slide back and forth in the transverse section 102 of the elbow 1 through the transmission mechanism, and pull the blockage in the longitudinal section 101 of the elbow 1 downward through the dragging mechanism 9 to force dredging.
