Description

Technical Field

[0001] This invention relates to the field of pipeline sewage dredging technology, and in particular to an ecological pipeline dredging system. Background Technology

[0002] Urban underground pipeline systems play a crucial role in urban life and production, responsible for flood control, drainage, and sewage disposal. In recent years, frequent torrential rains in major provinces and cities have posed a significant challenge to underground pipeline projects in municipal engineering. Typically, in public infrastructure construction, complex underground drainage pipe systems are laid to facilitate the discharge of rainwater and sewage. Over long-term use, foreign matter accumulates in these underground drainage pipes, necessitating the use of biological sludge-removing agents to clean them. The specific implementation involves adding the sludge-removing agent to a drainage well connected to the underground drainage pipe. The agent then enters the underground drainage pipe through the well to remove the accumulated foreign matter. However, a current problem is that the agent is usually manually added, which, due to human error, results in uneven distribution, wasting the agent and producing poor sludge-removing effects. Summary of the Invention

[0003] The purpose of this invention is to design a pipeline ecological dredging system to overcome the shortcomings of the above-mentioned technologies.

[0004] This invention designs a pipeline ecological dredging system, comprising a first cylinder and a second cylinder, which are coaxially connected and can be adjusted relative to each other along the axial direction. The top of the first cylinder is provided with a cover, and a suspension assembly is provided on the cover to allow the first cylinder to be hooked to the edge of the pipeline manhole via the suspension assembly. Both the first and second cylinders have cavities that are interconnected. A rotating cylinder is rotatably connected inside the second cylinder, and a rotating shaft is provided at the central axis of the rotating cylinder. A baffle assembly, comprising N baffles, is mounted on the rotating shaft. One end of each baffle is connected to the rotating shaft, and the other end extends to abut against the inner wall of the rotating cylinder. Adjacent baffles form an angle with the inner wall of the rotating cylinder. A storage cavity for temporarily storing the bacterial agent is formed by enclosing the rotating drum. The rotating drum has an opening that rotates axially with the drum. The storage cavity is aligned with the opening by the rotation of the partition assembly and the rotating drum, allowing the bacterial agent to fall into the storage cavity through the opening. A guide channel is provided above the rotating drum in the first cylinder. An inlet is provided on the peripheral wall of the first cylinder. One end of the guide channel is connected to the inlet, and the other end of the guide channel is corresponding to the opening. A connecting seat is provided below the rotating drum in the second cylinder. A pipe is provided inside the connecting seat. A rotating seat is rotatably connected to the bottom of the connecting seat. A side groove communicating with the pipe is provided inside the rotating seat. The bacterial agent falls from the pipe into the side groove. The side groove rotates with the rotating seat, causing the bacterial agent to be centrifugally dispersed and splashed under the action of centrifugal force.

[0005] Preferably, the suspension assembly includes a groove formed on the surface of the cover, a slider slidably connected in the groove, a hook provided on the slider, the bottom end of the hook being connected to the slider, and the top end being bent to form a horizontal suspension end so that the suspension end can fit against the horizontal edge of the wellhead.

[0006] Further optimization involves two sliding grooves, which intersect in a cross shape and are horizontally distributed on the surface of the cover. Each sliding groove has a slider and a hook at both ends, allowing the four hooks to form a square or rhomboid position through movement.

[0007] Further optimization involves providing a first mounting hole on the peripheral wall of the first cylinder and a second mounting hole on the peripheral wall of the second cylinder. Several second mounting holes are evenly distributed along the axial direction of the second cylinder. The first mounting holes and the second mounting holes are connected by fasteners, allowing the second cylinder to adjust its height relative to the first cylinder in the axial direction.

[0008] Preferably, a side annular groove is formed on the peripheral wall of the rotating seat, and several baffles are distributed at intervals in the side annular groove. From the cross-section or top view, the baffles are distributed in a centrifugal motion curve along the center of the side annular groove, and the side annular groove is divided into multiple circumferentially distributed side grooves between adjacent baffles.

[0009] Preferably, the bottom of the pipe is connected to a mounting base, and the mounting base is provided with a rotating fan for stirring.

[0010] Further optimization involves a transition cavity located below the pipe within the connecting seat. The bottom surface of the transition cavity is a raised arc surface, and a horizontal platform is provided at the center of the raised arc surface. The radial dimension of the horizontal platform is smaller than the radial dimension of the rotating fan blade.

[0011] The technical advantages of this invention are as follows: the main component of this invention is a rotating cylinder, and several partitions are rotatably connected coaxially inside the rotating cylinder. Adjacent partitions form a certain angle, and the ends of the partitions abut against the inner wall of the rotating cylinder, so that two adjacent partitions and the inner wall of the rotating cylinder enclose a storage cavity for storing microbial agents. Then, the microbial agents in the storage cavity are transferred and conveyed by rotating the partitions. Several partitions divide the rotating cylinder into multiple storage cavities, and each storage cavity can rotate and change position. Therefore, multiple microbial agents can be transferred simultaneously, which is very convenient. The bacteria agent can be evenly sprayed into the sewage at the sewer manhole. The bacteria agent can also be sprayed in different ranges by varying the rotation frequency of the rotating seat, thus making it suitable for sewage of different areas. This invention can be suspended at the opening of a drainage well using a suspension assembly. By adjusting the position of the hooks on the suspension assembly, it can be adapted to well openings of different shapes, making it highly versatile. The invention also includes a rotating fan blade that can stir multiple bacterial agents, thereby enabling the multiple bacterial agents to be automatically mixed and sprayed, which is very convenient.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0015] The present invention includes a first cylinder 1 and a second cylinder 2, which are coaxially connected together. A first mounting hole 19 is provided on the peripheral wall of the first cylinder 1, and a second mounting hole 20 is provided on the peripheral wall of the second cylinder 2. A plurality of second mounting holes 20 are evenly distributed along the axial direction of the second cylinder 2. The first mounting holes 19 and the second mounting holes 20 are connected by fasteners, so that the height position of the second cylinder 2 relative to the first cylinder 1 can be adjusted in the axial direction. That is, the second cylinder 2 can be adjusted in axial lifting position relative to the first cylinder 1, thereby realizing that the height dimension of the entire system equipment can be adjusted, which is suitable for sewer wells of different depths.

[0016] The top of the first cylinder 1 is provided with a cover 3, which can be detachably connected to the first cylinder 1 or fixedly connected to the first cylinder 1. The cover 3 is provided with a suspension assembly, which includes a groove 15 formed on the surface of the cover 3. A slider 16 is slidably connected in the groove 15. The slider 16 is provided with a hook 17. The bottom end of the hook 17 is connected to the slider 16, and the top end is bent outward to form a horizontal suspension end 18 so that the suspension end 18 can fit against the horizontal edge of the wellhead. In this embodiment, the hook 17 is a long strip plate structure. The hook 17 and the slider 16 are detachably connected by fasteners or fixed by welding. The connection is such that the chute 15 extends laterally to limit the slider 16, preventing it from axially disengaging from the chute 15. The slider 16 can reciprocate along the length of the chute 15. The slider 16 is manually driven to slide, which not only simplifies the structure but also makes it less prone to damage. It is particularly suitable for harsh natural environments and sewer conditions. For example, when the sewage flow is large during rain, an electric structure would be used to drive the slider 16. Because the opening 8 of the chute 15 is at the top, rainwater can easily accumulate in the chute 15. An electric structure would make the cover 3 more complex and heavier, and it would also be more susceptible to water damage. The first cylinder 1 is connected to the edge of the well opening of the pipe 12 via a suspension component hook 17, so that the first cylinder 1 and the second cylinder 2 are suspended together at the well opening via the hook 17, while the first cylinder 1 and the second cylinder 2 extend into the well.

[0017] Both the first cylindrical body 1 and the second cylindrical body 2 have cavities, and the cavities of the first cylindrical body 1 and the second cylindrical body 2 are interconnected. A rotating cylinder 4 is rotatably connected inside the second cylindrical body 2. A rotating shaft 5 is provided at the central axis of the rotating cylinder 4. A set of partitions 6 is provided on the rotating shaft 5 and rotates with the rotating shaft 5. The set of partitions 6 includes N partitions 6. One end of the N partitions 6 is connected to the rotating shaft 5 (N is an integer), and the other end extends to abut against the inner wall of the rotating cylinder 4, so that the N partitions 6 form a wind turbine-like structure. An angle is formed between two adjacent partitions 6. In this embodiment, there are six partitions 6, and the angle between adjacent partitions 6 is sixty degrees, that is, the six partitions 6 are uniform. The distribution is such that two adjacent partitions 6 and the inner wall of the rotating cylinder 4 enclose a storage cavity 7, which is used to temporarily store the bacterial agent. The rotating cylinder 4 has an opening 8, which rotates axially with the rotating cylinder 4. In the initial state, the rotating cylinder 4 rotates until the opening 8 faces upward, and then the partitions 6 also rotate upward, so that the uppermost storage cavity 7 forms a chamber with the opening 8 facing upward, so that the bacterial agent can fall into the uppermost storage cavity 7 through the opening 8. Then the rotating shaft 5 continues to rotate, and the partitions 6 rotate with the rotating shaft 5, so that the uppermost storage cavity 7 rotates along the inner wall of the rotating cylinder 4. During the rotation, the storage cavity 7 is a sealed chamber, and the bacterial agent in the storage cavity 7 will not leak.

[0018] The first cylinder 1 has a guide channel 9 located above the rotating cylinder 4. The guide channel 9 can be made of a flexible material or a corrugated pipe structure, which facilitates bending and adjusting the relative position of the first cylinder 1 and the second cylinder 2. The first cylinder 1 has a feed inlet 10 on its peripheral wall. One end of the guide channel 9 is connected to the feed inlet 10, and the other end of the guide channel 9 is corresponding to the opening 8. The bacterial agent is added from the feed inlet 10, and then passes through the guide channel 9 and the opening 8 of the rotating cylinder 4 in sequence before falling into the uppermost storage cavity 7. As the partition 6 rotates, the storage cavity 7 rotates, thereby transferring the bacterial agent.

[0019] The aforementioned rotating drum 4 and rotating shaft 5 are both arranged coaxially and are driven to rotate by corresponding different drive motors, so that the rotating drum 4 and rotating shaft 5 can rotate independently and in both directions.

[0020] The second cylinder 2 is located below the rotating cylinder 4 and is provided with a connecting seat 11. The connecting seat 11 is provided with a pipe 12. One end of the pipe 12 is aligned with the bottom of the rotating cylinder 4. The storage chamber 7 containing the bacterial agent is first rotated to the bottom, that is, directly facing the top of the pipe 12. Then the rotating cylinder 4 rotates, so that the opening 8 of the rotating cylinder 4 rotates to the bottom. At this time, the opening 8 of the rotating cylinder 4 becomes an outlet, and the bacterial agent in the storage chamber 7 falls from the outlet into the pipe 12.

[0021] A rotating seat 13 is rotatably connected to the bottom of the connecting seat 11. An installation cavity is opened inside the bottom of the connecting seat 11, and a drive motor is installed in the installation cavity. The installation cavity forms a sealed cavity. The output end of the drive motor is connected to the rotating seat 13. A side groove 14 communicating with the pipe 12 is opened in the rotating seat 13. The bacterial agent falls from the pipe 12 into the side groove 14. The side groove 14 rotates with the rotating seat 13. The rotation generates centrifugal force. Under the action of centrifugal force, the bacterial agent is thrown out from the side groove 14, forming a uniform, circumferential centrifugal dispersion spray. This allows the bacterial agent to be evenly sprinkled in the sewage, so that the bacterial agent can be evenly dissolved without edema, achieving a better sludge removal effect. Compared with all the bacterial agents added at once, the sludge removal effect is better, and the waste of bacterial agents is avoided.

[0022] Furthermore, a side annular groove 21 is provided on the peripheral wall of the rotating seat 13. Several baffles 22 are distributed at intervals in the side annular groove 21. From the cross-section or top view, the baffles 22 are distributed in a centrifugal motion curve along the center of the side annular groove 21. The adjacent baffles 22 divide the side annular groove 21 into multiple circumferentially distributed side grooves 14. In this way, when the bacterial agent in the side groove 14 is thrown away, the baffles 22 can play a certain guiding role for the bacterial agent, making the movement trajectory of the bacterial agent more uniform and preventing it from being thrown out in a pile.

[0023] Furthermore, there are two swivels 15, which are arranged in a cross shape and horizontally distributed on the surface of the cover 3. Each swivel 15 has a slider 16 and a hook 17 at each end, so that the four hooks 17 can be moved to form a square or rhomboid position. That is, the position of each hook 17 can be adjusted individually. In this way, the four positions that can form rectangles, squares and rhomboids are suitable for well openings of different shapes. For example, the rectangle and rhomboid positions are suitable for elliptical well openings, the square position is suitable for circular well openings, and even some irregularly shaped well openings can be used. Therefore, the four hooks 17 of the present invention can be used for well openings of different shapes, which is very convenient.

[0024] Furthermore, a transition cavity 25 is provided inside the connecting seat 11 below the pipe 12. The bottom surface of the transition cavity 25 is a circular arc protrusion 26, which facilitates the bacterial agent to slide down along the arc surface into the side groove 14. A horizontal platform 27 is provided at the center of the circular arc protrusion 26. The bacterial agent will first fall onto the horizontal platform 27. A mounting seat 23 is lifted and connected to the bottom of the pipe 12. A lifting drive structure is provided inside the second cylinder 2 to drive the mounting seat 23 to lift and lower. A rotating fan 24 for stirring is provided on the mounting seat 23. A drive motor for driving the rotating fan 24 to rotate is also provided on the mounting seat 23. The rotating fan 24 descends to the horizontal platform 27 with the mounting seat 23 and stirs the bacterial agent that falls onto the horizontal platform 27. With the centrifugal force generated by stirring, the bacterial agent on the horizontal platform 27 will slide down along the side wall of the circular arc protrusion 26.

[0025] Furthermore, the radial dimension of the platform surface 27 is smaller than the radial dimension of the rotating fan blade 24, allowing the rotating fan blade 24 to rotate on the platform surface 27 to achieve the purpose of stirring. After being stirred evenly, the bacterial agent on the platform surface 27 is blown off as the rotating fan blade 24 accelerates its rotation. Alternatively, the mounting base 23 can drive the rotating fan blade 24 to rise above the stirred bacterial agent, and the rotating fan blade 24 forms a fan effect, blowing air downwards to blow the bacterial agent off the platform surface 27. This is suitable for situations where multiple solid bacterial agents need to be mixed.

[0026] Of course, the bacterial agent of the present invention can be solid or liquid. When it is liquid, it is stirred in the air by the rotating fan 24 during the fall from the pipe 12. When it is solid, it is stirred on the horizontal platform 27 by the rotating fan 24. The rotating fan 24 can stir and blow down the stirred bacterial agent by different rotation speeds.

[0027] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
