Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a silt clearing and anti-clogging structure for water conservancy construction. Background Art

[0002] In the daily operation and maintenance of water conservancy projects, pipes, as a key component for conveying water, often form siltation inside due to the deposition of silt, impurities and other substances carried by the water flow. These silts will gradually reduce the effective flow cross-section of the pipes, causing pipe blockage and seriously affecting the normal operation of water conservancy projects.

[0003] In water conservancy systems, the inner diameter of the pipeline may change due to various factors such as design requirements, construction conditions, and operating environment. However, during the desilting process, the traditional anti-clogging structure cannot adjust the desilting device in time according to the change in the inner diameter of the pipeline, which may lead to damage to the desilting device and pipeline, or incomplete removal of silt in the pipeline.

[0004] Patent document CN114210671B discloses a silt removal device for preventing pipeline blockage in water conservancy projects. The above patent realizes automatic scraping of silt inside the pipeline, can automatically retract or unfold the scraper, and automatically spray softening liquid on the silt, which is conducive to chiseling hard silt.

[0005] In summary, the above patents automatically scrape away the silt inside the pipe by automatically retracting or unfolding the scraper, thereby solving the problem of wasting manpower to manually move the drill bit to clean the silt. However, there is still room for improvement in cleaning pipes with varying inner diameters. The present application solves the problem that the silt cleaning equipment cannot be applied to pipes with varying inner diameters by automatically adjusting the relative position of the silt cleaning ring through a silt cleaning component.

[0023] See also Figure 1 , Figure 2 and Figure 3 , an embodiment of the present invention: a silting and anti-blocking structure for water conservancy construction, comprising a silting vehicle body 1 and a silting assembly, wherein the silting vehicle body 1 is provided with a silting assembly; the silting assembly comprises: an adjusting ring 9, a movable shaft 5 is movably installed on the side wall of the silting vehicle body 1, an adjusting ring 9 and a connecting column 6 are fixedly installed on the outer wall of the movable shaft 5, a third motor 22 is equidistantly installed in the adjusting ring 9, the third motor 22 is connected to a first adjusting rod 24 through a third rotating shaft 23, the first adjusting rod 24 is connected to a second adjusting rod 25 through a rotating shaft, the second adjusting rod 25 is connected to a lifting shaft 7 through a rotating shaft, a connecting column 6 is movably sleeved on the outer wall of the lifting shaft 7, a pressure sensor 26 is fixedly connected to the side wall of the connecting column 6, the pressure sensor 26 is connected to a connector 10 through a buffer spring 27, a silting ring 11 is detachably connected to the outer wall of the connector 10, and the pressure sensor 2 6 is connected to a third motor 22 via Bluetooth; the inner wall of the dredging vehicle body 1 is fixedly connected to the first motor 12, and the side wall of the first motor 12 is movably installed with a first rotating shaft 13, the first rotating shaft 13 penetrates the dredging vehicle body 1, and the outer wall of the first rotating shaft 13 is movably covered with a connecting seat 4, the side wall of the crushing body 3 is fixedly connected to a movable shaft 5, the outer wall of the first rotating shaft 13 is fixedly installed with a first gear 63, the side wall of the first gear 63 is meshingly installed with a second gear 64, the second gear 64 is rotatably connected to the connecting seat 4 through the rotating shaft, and the side wall of the crushing body 3 is fixedly connected with an annular gear plate 65, and the annular gear plate 65 is meshed with the second gear 64; the inner wall of the dredging vehicle body 1 is fixedly installed with a suction box 20, the outer wall of the dredging vehicle body 1 is provided with a suction groove 21, the suction groove 21 is communicated with the suction box 20, the side wall of the suction box 20 is fixedly installed with a suction pipe 19, the suction box 20 is communicated with the suction pipe 19, and the side wall of the suction box 20 is fixedly connected with a filter screen 71.

[0024] Furthermore, when the dredging vehicle body 1 is dredging in the pipeline, the first motor 12 is started, the first motor 12 drives the first rotating shaft 13 to rotate, the first rotating shaft 13 drives the first gear 63 to rotate, the first gear 63 drives the second gear 64 to rotate, the second gear 64 drives the annular gear plate 65 to rotate, the annular gear plate 65 drives the crushing body 3 to rotate, the crushing body 3 drives the movable shaft 5 to rotate, the movable shaft 5 drives the connecting column 6, the connecting column 6 drives the lifting shaft 7, the lifting shaft 7 drives the connecting body 10, and the connecting body 10 drives the dredging ring 11, so that the crushing body 3 breaks the silt or other impurities in the pipeline into small pieces, and the dredging ring 11 removes and crushes the silt or other impurities adhering to the inner wall of the pipeline, so as to prevent the silt or other impurities from clogging the pipeline; During the movement of the dredging vehicle body 1 in the pipeline, when the inner diameter of the pipeline becomes smaller, the pipeline squeezes the dredging ring 11, and the dredging ring 11 drives the connecting body 10 to compress the buffer spring 27, and the buffer spring 27 elastically squeezes the pressure sensor 26. When the pressure sensor 26 detects that the pressure data is higher than the set pressure range, the pressure sensor 26 controls the third motor 22 to rotate forward, the third motor 22 drives the third rotating shaft 23, the third rotating shaft 23 drives the first adjusting rod 24, the first adjusting rod 24 drives the second adjusting rod 25, and the second adjusting rod 25 drives the lifting shaft 7 in the connecting column 6. The lifting shaft 7 drives the connector 10 and the dredging ring 11 to move closer to the movable shaft 5. When the pressure sensor 26 detects that the pressure data is restored to the set pressure range, the pressure sensor 26 controls the third motor 22 to turn off, thereby preventing the dredging ring 11 from excessively squeezing the pipeline due to the reduction of the inner diameter of the pipeline, thereby preventing the dredging ring 11 or the pipeline from being damaged. At the same time, the buffer spring 27 is set to ensure that when the dredging vehicle body 1 encounters a decrease in the inner diameter of the pipeline, the dredging ring 11 and the connector 10 will first compress the buffer spring 27 to preliminarily adjust the position of the dredging ring 11 to avoid the inner diameter of the pipeline changing too fast and causing damage. The position of the dredging ring 11 is not adjusted in time, thereby affecting the dredging ring 11 and the pipeline; when the inner diameter of the pipeline becomes larger, the pressure applied by the pipeline to the dredging ring 11 and the connector 10 will become smaller, and the buffer spring 27 will gradually recover from the compressed state to the original state, and the elastic force applied by the buffer spring 27 to the pressure sensor 26 will become smaller. When the pressure sensor 26 detects that the pressure data is lower than the set pressure range, the pressure sensor 26 controls the third motor 22 to rotate in the opposite direction, and the third motor 22 drives the third rotating shaft 23, the first adjusting rod 24, the second adjusting rod 25, and the lifting shaft 7. The lifting shaft 7 drives the connector 10 and the dredging ring 11 away from the movable shaft 5. When the pressure sensor 26 detects that the pressure data returns to the set pressure range, the pressure sensor 26 controls the third motor 22 to turn off, so that the dredging ring 11 can smoothly clean the silt on the inner wall of the pipeline, and avoid the dredging ring 11 being unable to clean the silt adhering to the inner wall of the pipeline due to the increase in the inner diameter of the pipeline, thereby ensuring the dredging effect, thereby ensuring that the dredging ring 11 always maintains a suitable relative position with the pipeline, so that the dredging and anti-blocking structure can automatically adjust the dredging components when the inner diameter of the pipeline changes.

[0025] See also Figure 1 , Figure 2 and Figure 8, an embodiment of the present invention: a silting and anti-blocking structure for water conservancy construction, the silting vehicle body 1 has a movable shaft 5 movably installed on its side wall, an adjusting ring 9 and a connecting column 6 are fixedly installed on its outer wall, a third motor 22 is equidistantly installed in the adjusting ring 9, the third motor 22 is connected to a first adjusting rod 24 via a third rotating shaft 23, the first adjusting rod 24 is connected to a second adjusting rod 25 via a rotating shaft, the second adjusting rod 25 is connected to a lifting shaft 7 via a rotating shaft, a connecting column 6 is movably sleeved on its outer wall, a pressure sensor 26 is fixedly connected to its side wall with a connecting body 10 via a buffer spring 27, a silting ring 11 is detachably connected to the outer wall of the connecting body 10, and the pressure sensor 26 is connected to the outer wall of the connecting body 10 via a buffer spring 27. A third motor 22 is connected via Bluetooth; a limiting component is arranged in the adjusting ring 9, and the limiting component is used to limit the rotation of the first adjusting rod 24; the limiting component includes: a limiting groove 52, an electric push rod 55, a sixth spring 56 and a gear block 57; the outer wall of the adjusting ring 9 is provided with limiting grooves 52 at equal intervals, the side wall of the first adjusting rod 24 is fixedly connected to the limiting column 53, the limiting groove 52 is movably mounted on the outer wall of the limiting column 53, a gear ring 54 is fixedly installed on the outer wall of the third rotating shaft 23, an electric push rod 55 is fixedly installed at equal intervals in the adjusting ring 9, the side wall of the electric push rod 55 is fixedly connected to the sixth spring 56, the side wall of the sixth spring 56 is fixedly connected to the gear block 57, the outer wall of the gear block 57 is movably mounted with the adjusting ring 9, the gear block 57 is in contact with the gear ring 54, and the electric push rod 55 is connected to the pressure sensor 26 via Bluetooth.

[0026] Furthermore, when the dredging vehicle body 1 encounters a change in the inner diameter of the pipeline, and the pressure detection data of the pressure sensor 26 in the equipment is higher or lower than the set pressure range, the pressure sensor 26 controls the electric push rod 55 and the third motor 22 to start, and the electric push rod 55 drives the sixth spring 56 to gradually restore from the compressed state to the original state. At the same time, the electric push rod 55 drives the gear block 57 through the sixth spring 56, so that the gear block 57 no longer conflicts with the gear ring 54. At this time, the third motor 22 can smoothly drive the third rotating shaft 23, and the third rotating shaft 23 drives the gear ring 54 to rotate, the third rotating shaft 23, the first adjusting rod 24, the second adjusting rod 25, the lifting shaft 7, the connecting body 10, and the dredging ring 11, thereby adjusting the position of the dredging ring 11. When the pressure sensor 26 detects that the pressure data has returned to the set pressure range, the pressure sensor 26 turns off the third motor 22. The machine 22 starts the electric push rod 55 again, and the electric push rod 55 compresses the sixth spring 56, so that the electric push rod 55 drives the tooth block 57 to contact and mesh with the gear ring 54 again through the sixth spring 56, so that the electric push rod 55 compresses the sixth spring 56 to the limit compression state. When the tooth block 57 is not fully meshed with the gear ring 54, when the gear ring 54 rotates slightly due to external force, the sixth spring 56 drives the tooth block 57 to mesh with the gear ring 54, thereby ensuring that the tooth block 57 contacts the gear ring 54 and avoiding the rotation of the third rotating shaft 23, thereby preventing the dredging ring 11 with adjusted position from being displaced due to external force, thereby affecting the dredging effect of the dredging ring 11 or causing damage to the pipeline of the dredging ring 11. At the same time, under the action of the limiting column 53 and the limiting groove 52, the activity range of the dredging ring 11 is limited to avoid excessive adjustment of the dredging ring 11.

[0028] Further, the first motor 12 is started, and the first motor 12 drives the first rotating shaft 13, the first gear 63, the second gear 64, the annular gear plate 65, and the crushing body 3. The crushing body 3 crushes the sludge blocks or other impurities in the pipeline. The sawtooth pattern 8 on the crushing body 3 increases the contact area between the sawtooth pattern 8 and the sludge or other impurities, thereby improving the crushing efficiency. When the crushing body 3 rotates, the crushing body 3 drives the triggering body 73 to rotate, so that the triggering body 73 contacts the hemispherical body 74 on the connecting seat 4 in turn, the triggering body 73 contacts the hemispherical body 74, the hemispherical body 74 drives the triggering body 73 to move, and the triggering body 73 drives the cutting structure 72 to move, so that the cutting structure 72 gradually enters the sawtooth pattern 8 and gradually makes the outer part of the cutting structure 72 Gradually move out of the sawtooth pattern 8, the cutting structure 72 drives the limiting body 76 to stretch the seventh spring 75; when the trigger body 73 is no longer in contact with the hemispherical body 74, the seventh spring 75 recovers from the stretched state to the original state, the seventh spring 75 drives the limiting body 76 to reset, and the limiting body 76 drives the cutting structure 72 to reset; during the rotation of the crushing body 3, under the action of the trigger body 73, the hemispherical body 74 and the seventh spring 75, the cutting structure 72 repeats the process of partially moving out of the sawtooth pattern 8 and resetting, so that the cutting structure 72 can squeeze the silt or other impurities remaining in the sawtooth pattern 8 out of the sawtooth pattern 8, thereby ensuring the crushing efficiency. At the same time, the cutting structure 72 can shred the debris that the crushing body 3 cannot crush, such as plastic bags, ropes, weeds, etc., thereby ensuring the dredging effect.

[0030] Furthermore, as the dredging vehicle body 1 continuously cleans the silt or other impurities in the pipeline, the dredging ring 11 will gradually wear out, thereby affecting the dredging effect. When the dredging ring 11 needs to be replaced, the operator moves the blocking plates 38 on both sides of the dredging ring 11 to make the blocking plates 38 compress the second spring 39 so that the blocking plates 38 no longer block the disassembly and assembly groove 37. At this time, the operator uses a tool to insert the disassembly and assembly groove 37, thereby rotating the rotating body 36 in the forward direction, and the rotating body 36 drives the second rotating rod 35 to rotate, and the second rotating rod 35 drives the second bevel gear 34 to rotate, and the first The second bevel gear 34 drives the first bevel gear 33 to rotate, and the first bevel gear 33 drives the first rotating rod 32 to rotate.

Under the elastic force of the first spring 30, the first spring 30 drives the first plug post 29 to insert into the first installation groove 28, thereby completing the initial positioning of the dredging ring 11 during installation to avoid the dredging ring 11 being installed loosely due to operational errors. At this time, the rotating body 36 is rotated in the opposite direction, and the rotating body 36 drives the second rotating rod 35, the second bevel gear 34, the first bevel gear 33, the first rotating rod 32, and the extrusion block 31. , the extrusion block 31 re-compresses the first spring 30, so that the first spring 30 is in an extreme compression state, thereby ensuring that the first plug 29 fixes the connector 10, and completing the replacement and installation of the dredging ring 11; after the dredging ring 11 is replaced, the blocking plate 38 is no longer applied with external force, and the blocking plate 38 is reset under the action of the elastic force of the second spring 39, so that the blocking plate 38 blocks the disassembly and assembly groove 37, avoiding sewage or sludge disassembly and assembly groove 37, preventing sludge from clogging the disassembly and assembly groove 37 or corroding the rotating body 36, thereby affecting the replacement and installation of the dredging ring 11.

[0032] Further, when disassembling the desilting ring 11 through the sliding disassembly structure, the operator first moves the second push plate 50 to make the second push plate 50 close to the third push plate 51, and the second push plate 50 drives the push column 49, and the push column 49 drives the first push plate 47 to compress the fifth spring 48, and the push column 49 gradually inserts into the inclined groove 46. Under the action of the inclined groove 46, the push column 49 drives the plug 45 to compress the fourth spring 44, so that the plug 45 moves out of the third installation groove 41. At this time, the second push plate 50 and the third push plate 51 are moved at the same time. 1, the third push plate 51 drives the second plug post 42 to compress the third spring 43, so that the second plug post 42 moves out of the second installation groove 40, thereby releasing the second plug post 42 and the plug block 45 from fixing the connecting body 10, removing the dredging ring 11 from the connecting body 10, and installing a new dredging ring 11 on the connecting body 10, stopping the external force applied to the second push plate 50 and the third push plate 51, and the third spring 43 recovers from the compressed state to the original state, and the third spring 43 drives the second plug post 42 to reset, so that the second plug post 42 is inserted into the connecting body 10. When the second mounting groove 40 is inserted, when the plug block 45 moves to above the third mounting groove 41, the fourth spring 44 returns to its original state from the compressed state, and the fourth spring 44 drives the plug block 45 to move, so that the plug block 45 is inserted into the third mounting groove 41, so that the plug block 45 and the second plug column 42 fix the connector 10, thereby fixing the dredging ring 11 on the connector 10; when removing the dredging ring 11, the second push plate 50 must be moved first, so that the second push plate 50 is close to the third push plate 51, at this time the third push plate 51 can move, and by moving the second push plate 50 and the third push plate 51 at the same time, the fixation of the dredging ring 11 is released, because the initial moving direction of the second push plate 50 is opposite to the moving direction of the third push plate 51, and the initial moving direction of the second push plate 50 is opposite to the moving direction of the second push plate 50 again, thereby preventing the dredging ring 11 from being no longer firmly installed on the equipment due to external force; compared with the rotating disassembly structure, the sliding disassembly structure does not require tools for disassembly and replacement, and the operation is simpler.
