Description

Technical Field

[0001] This application relates to the technical field of engineering machinery, and in particular to a drainage pipe cleaning device. Background Technology

[0002] Rainwater pipes need to be cleaned of accumulated silt promptly to ensure unobstructed flow. There are two main cleaning methods: the first is manual cleaning, where workers use hand tools to clean the pipes. This method is only suitable for large-diameter pipes accessible by hand, and cannot clean small-diameter pipes, limiting its applicability. The second method is high-pressure water jet flushing, where a high-pressure water jet gently sprays the rainwater pipe, while a vacuum truck simultaneously removes the sludge from the other end of the pipe. This method can clean rainwater pipes of various diameters, but it is less efficient, consumes a large amount of water, generates a large amount of wastewater, and has high equipment costs, making it difficult to widely adopt. Summary of the Invention

[0003] In order to improve the cleaning efficiency of small-diameter rainwater pipes and reduce the water used for cleaning, this application provides a drainage pipe cleaning device.

[0004] The drainage pipe cleaning device provided in this application adopts the following technical solution: A drainage pipe cleaning device, comprising: The vehicle body has a collection trough at the rear end; The walking tracks are mounted on the vehicle body and are used to move the vehicle body through the drainage pipe; The cutting assembly includes a cutting frame connected to the front end of the vehicle body, a cutting track fitted on the cutting frame, and a cutting drive component that drives the cutting track to slide along the cutting frame. The cutting drive component is mounted on the cutting frame. The cutting track has an inclined downward loading end for cutting and transporting sludge, and an inclined upward discharge end extending to the top of the vehicle body on the side away from the loading end. The conveyor belt is located on top of the vehicle body, with one end below the discharge end and the other end above the collection trough.

[0005] By adopting the above technical solution, the walking track enables the vehicle to move and walk in the drainage pipe. The cutting track of the cutting component cuts through the silt, sediment and other debris in the rainwater pipe, shovels up the debris and finally dumps it onto the conveyor belt. The conveyor belt transports the debris into the collection tank, thus realizing the cleaning of debris in the rainwater pipe. The cleaning equipment itself can move in the rainwater pipe, and its compact structure allows it to enter narrow pipes for construction. At the same time, the construction process is continuous, without increasing stress, and continuous operation can be guaranteed with relatively low power. The construction efficiency is high and the construction cost is low. In addition, it does not require a large amount of water for cleaning, thus saving water resources.

[0006] Optionally, the cutting track is provided with multiple rows of mud loosening blades and multiple mud scraping plates along the circumferential direction, with multiple mud loosening blades spaced apart in each row along the transverse direction of the cutting track.

[0007] By adopting the above technical solution, the mud loosening blade can cut through harder silt, and the mud shovel will scoop up the silt onto the cutting track surface, which can quickly and efficiently remove silt and improve the removal efficiency.

[0008] Optionally, the loosening blades in adjacent rows are staggered.

[0009] By adopting the above technical solution, the staggered mud-loosening blades can break the silt into smaller and looser pieces, making it easier for the mud-shoveling plate to scoop up the silt.

[0010] Optionally, the ends of each row of mud-loosening blades away from the cutting track collectively form an arc shape adapted to the shape of the inner wall of the drain pipe, and the ends of the mud-shoveling plates away from the cutting track are arc shapes adapted to the shape of the inner wall of the drain pipe.

[0011] By adopting the above technical solution, the mud loosening blade can adapt to the shape of the bottom of the inner wall of the rainwater pipe, and the mud cutting is more thorough. The mud scraper can also adapt to the shape of the bottom of the inner wall of the rainwater pipe. After scraping up the mud, there is less residue at the bottom of the rainwater pipe, which improves the cleaning effect of the rainwater pipe.

[0012] Optionally, the cleaning equipment also includes a sludge removal assembly, which includes: The sludge pump is installed inside the collection tank; The sludge discharge pipe connects to the outlet of the sludge pump at one end and extends out of the drain pipe at the other end.

[0013] By adopting the above technical solution, when there is a large amount of sludge collected in the collection tank, a sludge pump can be used to extract the sludge and discharge it to the outside of the rainwater pipe through the sludge discharge pipe, so as to prevent the cleaning equipment from being overloaded and unable to work properly.

[0014] Optionally, the sludge removal assembly further includes: Mounting bracket, connected to the rear end of the vehicle body; The winding reel, rotatably connected to the mounting frame, is used to wind up the mud discharge pipe.

[0015] By adopting the above technical solution, the winding wheel can wind up a long mud discharge pipe and release or retract the mud discharge pipe when the vehicle moves, without affecting the normal movement of the vehicle.

[0016] Optionally, the sludge discharge pipe includes a rigid pipe connected to the outlet of the sludge pump and a flexible pipe wound on a winding reel, wherein the rigid pipe passes through the winding reel along the central axis of the winding reel and is rotatably connected to the flexible pipe.

[0017] By adopting the above technical solution, the rigid tube is fixed in position, and the flexible tube rotates synchronously when the winding wheel rotates, but this does not affect its connection with the rigid tube, so as to facilitate the laying operation of the flexible tube.

[0018] Optionally, a scraper is connected to the wall of the collection tank, and the scraper abuts against the belt surface of the transmission belt.

[0019] By adopting the above technical solution, the scraper can remove the sludge adhering to the surface of the conveyor belt, making the conveyor belt more efficient in transporting sludge. Because the scraper is set in the collection trough, the sludge will only fall into the collection trough.

[0020] Optionally, the cleaning equipment also includes a mixing assembly, which includes: The stirring shaft is rotatably connected to the wall of the collecting tank; The stirring blades are connected to the stirring shaft, and multiple sets are provided along the axial direction of the stirring shaft, with multiple blades provided in each set along the circumference of the stirring shaft; The stirring motor is mounted on the vehicle body, and its output shaft is connected to the stirring shaft.

[0021] By adopting the above technical solution, the stirring motor drives the stirring shaft to rotate, and the stirring blades on the stirring shaft can stir the sludge in the collection tank, making the sludge more uniform and more fluid, which is beneficial for the sludge pump to suck up the sludge.

[0022] Optionally, the cleaning equipment also includes a fixed frame that is fixedly connected to the vehicle body, and the fixed frame has a through hole; the fixed frame is also threadedly connected with a fixing bolt, and the threaded end of the fixing bolt passes through the through hole of the fixed frame.

[0023] By adopting the above technical solution, the water pipe can be inserted into the fixed frame, the pipe opening can be aligned with the collection tank, and the fixing bolts can be tightened to press the water pipe. When the sludge is relatively thick, water can be flushed into the collection tank to dilute the sludge, which makes it easier for the sludge pump to suck up the sludge.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The walking track enables the vehicle to move through the drainage pipe. The cutting track of the cutting component cuts through the silt, sediment, and other debris in the rainwater pipe, scoops up the debris, and finally dumps it onto the conveyor belt. The conveyor belt transports the debris into the collection tank, thus cleaning the debris in the rainwater pipe. The cleaning equipment itself can move in the rainwater pipe, and its compact structure allows it to enter narrow pipes for construction. At the same time, the construction process is continuous, without increasing stress, and continuous operation can be guaranteed with relatively low power. The construction efficiency is high and the construction cost is low. In addition, it does not require a large amount of water for cleaning, thus saving water resources. 2. The sludge loosening knife can adapt to the shape of the bottom of the inner wall of the rainwater pipe, and cut the silt more thoroughly. The shovel plate can also adapt to the shape of the bottom of the inner wall of the rainwater pipe. After shoveling up the silt, there is less residue at the bottom of the rainwater pipe, which improves the cleaning effect of the rainwater pipe. 3. The scraper can remove the sludge adhering to the surface of the conveyor belt, making the conveyor belt more efficient in transporting sludge. Because the scraper is set in the collection trough, the sludge will only fall into the collection trough. 4. The water pipe can be inserted into the fixed frame, with the pipe opening aligned with the collection tank. Tighten the fixing bolts to press the water pipe tightly. When the sludge is relatively thick, water can be flushed into the collection tank to dilute the sludge, making it easier for the sludge pump to draw the sludge. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0027] This application proposes a drainage pipe cleaning device, referring to... Figure 1The system includes a vehicle body 1, a track 2, a cutting assembly 3, a conveyor belt 4, a sludge discharge assembly 5, and a mixing assembly 6. A collection trough 11 is located at the top of the rear end of the vehicle body 1; the track 2 is located at the bottom of the vehicle body 1 and is used to move the vehicle body 1 through the drainage pipe; the cutting assembly 3 is located at the front end of the vehicle body 1 and is used to cut and excavate sludge; the conveyor belt 4 is located at the top of the vehicle body 1 and is used to transport the sludge excavated by the cutting assembly 3 into the collection trough 11; the sludge discharge assembly 5 is located at the rear end of the vehicle body 1 and is used to discharge the sludge out of the drainage pipe; the mixing assembly 6 is located inside the collection trough 11 and is used to mix the sludge within the collection trough 11.

[0028] The vehicle body 1 is a cuboid with a collection trough 11 at the top of the rear end for storing sludge. A battery is installed inside the vehicle body 1 to power the various power-consuming components of the cleaning equipment. Tracks 2 are located at the bottom of the vehicle body 1, allowing it to move freely within the drainage pipe.

[0029] Reference Figure 1 and Figure 2 The cutting assembly 3 includes a cutting frame 31, a cutting track 32, and a cutting drive component 33. The cutting frame 31 is welded to the front end of the vehicle body 1 and includes multiple rotatably connected track wheels. The cutting track 32 is fitted onto the frame and engages with the track wheels. The cutting drive component 33 is a geared motor mounted on the frame, with its output shaft connected to a set of track wheels, enabling the cutting track 32 to rotate circumferentially along the cutting frame 31 by rotating the track wheels. The cutting track 32 is inclined overall, with one end facing the bottom of the drain pipe as the loading end 321, used for cutting and shoveling sludge; the other end extends to the top of the vehicle body 1 as the discharge end 322, used for unloading the carried sludge.

[0030] Multiple sets of loosening blades 323 are fixedly connected circumferentially to the cutting track 32. Each set of loosening blades 323 is evenly spaced along the direction perpendicular to the running direction of the cutting track 32, and adjacent sets of loosening blades 323 are staggered. The cross-section of the loosening blades 323 is an isosceles triangle. When the loosening blades 323 come into contact with the silt, the silt is cut into loose clumps. The staggered arrangement of adjacent rows of loosening blades 323 can improve the cutting effect. A mud-shoveling plate 324 is also fixedly connected to the cutting track 32. The mud-shoveling plate 324 is an arc-shaped plate with an arc opening facing the running direction of the cutting track 32, which can shovel up the silt and pour it onto the surface of the cutting track 32. The mud-shoveling plates 324 are evenly spaced along the circumference of the cutting track 32, and two sets of loosening blades 323 are provided between two adjacent mud-shoveling plates 324. The ends of the loosening blades 323 located away from the cutting track surface 32 in the same row form an arc shape, which matches the shape of the inner bottom of the drain pipe, allowing the loosening blades 323 to cut the silt inside the drain pipe more thoroughly. The end of the shovel plate 324 located away from the cutting track surface 32 is also an arc shape that matches the shape of the inner bottom of the drain pipe, enabling it to shovel up the silt more thoroughly.

[0031] Reference Figure 1 and Figure 3 The conveyor belt 4 is located at the top of the vehicle body 1, with one end below the discharge end 322 to receive the sludge delivered by the cutting track 32, and the other end extending above the collection trough 11 to pour the sludge into the collection trough 11 for storage. A scraper 12 is welded to the wall of the collection trough 11 near the front end of the vehicle. The scraper 12 is L-shaped, with one end horizontally welded to the wall of the collection trough 11; the other end is bent upwards at an angle, abutting against the surface of the conveyor belt 4. The sludge scraped off by the scraper 12 falls down into the collection trough 11.

[0032] A stirring assembly 6 is disposed within the collection tank 11 and includes a stirring shaft 61, stirring blades 62, and a stirring motor 63. The stirring shaft 61 is rotatably connected to the vehicle body 1 and passes through the collection tank 11, with its central axis perpendicular to the direction of movement of the vehicle body 1. Multiple sets of stirring blades 62 are welded to the stirring shaft 61, arranged along the axial direction of the stirring shaft 61, with each set of blades evenly spaced circumferentially along the stirring shaft 61. In this embodiment, the stirring blades 62 are cylindrical, arranged perpendicularly to the stirring shaft 61, with three blades in each set. The stirring motor 63 is disposed on the outer wall of the vehicle body 1, with its output shaft connected to the stirring shaft 61, driving the stirring shaft 61 to rotate. Two sets of the stirring assembly 6 are provided, located on opposite sides of the collection tank 11, for stirring the sludge to make it more uniform.

[0033] Reference Figure 3 and Figure 4 A mounting bracket 13 is welded onto the vehicle body 1. The mounting bracket 13 is gate-shaped and forms a through hole with the vehicle body 1, located at the top of the rear end of the vehicle body 1. A fixing bolt 14 is threadedly connected to the middle of the mounting bracket 13, and the threaded end of the fixing bolt 14 passes through the mounting bracket 13 and into the through hole. A water pipe can be inserted into the through hole under the mounting bracket 13, and the fixing bolt 14 can be tightened to press the water pipe into the collection tank 11. When the sludge in the collection tank 11 is relatively viscous, water can be injected into the collection tank 11, and the stirring component 6 can be used to stir it to thin the sludge, making it easier for the sludge discharge component 5 to discharge the sludge.

[0034] Reference Figure 3 and Figure 5The sludge discharge assembly 5 includes a sludge pump 51, a sludge discharge pipe 52, a mounting frame 53, and a take-up reel 54. The sludge pump 51 is located at the bottom of the collection tank 11 and is used to pump and absorb the sludge within the tank. The mounting frame 53 is welded to the rear end of the vehicle body 1. The take-up reel 54 is rotatably connected to the mounting frame 53 and is used to wind up the sludge discharge pipe 52, performing pipe winding and unwinding operations as the vehicle body 1 moves. A take-up motor 541 is mounted on the mounting frame 53, and the output shaft of the take-up motor 541 is connected to the take-up reel 54. The sludge discharge pipe 52 includes a rigid pipe 521 and a flexible pipe 522. One end of the rigid pipe 521 is connected to the outlet of the sludge pump 51, and the other end passes through the collection tank 1 and coaxially enters the take-up reel 54. The rigid pipe 521 is rotatably connected to the take-up reel 54. Multiple support plates are inserted into the vehicle body 1, and the rigid pipe 521 passes through these support plates, allowing the support plates to support and fix the rigid pipe 521. A swivel joint 523 is provided at one end of the rigid tube 521 that enters the winding reel 54. The swivel joint 523 is rotatably connected to the flexible tube 522. One end of the flexible tube 522 is connected to the swivel joint 523, and the other end passes through the winding reel 54 radially and is wound around the winding reel 54. When the winding motor 541 drives the winding reel 54 to rotate, the winding reel 54 can realize the winding and unwinding operation of the flexible tube 522, so that the cleaning equipment can move freely in the drainage pipe.

[0035] The implementation principle of this application embodiment is as follows: A water pipe is inserted into the fixing frame 13 and tightened using fixing bolts 14; the cleaning equipment is placed into the drainage pipe, and the cutting drive 33 is activated to cause the cutting conveyor belt 4 to cut and excavate the sludge. The excavated sludge is sent to the transmission belt and then into the collection tank 11; the walking track 2 operates, causing the vehicle body 1 to move forward; the winding motor 541 drives the winding wheel 54 to rotate, lowering the flexible pipe 522, allowing the vehicle body 1 to move forward normally. When a certain amount of sludge is collected in the collection tank 11, the sludge pump 51 is activated, and the sludge pump 51 discharges the sludge through the sludge discharge pipe 52 out of the drainage pipe. If the sludge is relatively viscous, water is injected into the collection tank 11 through the water pipe, the stirring assembly 6 is activated to stir the sludge, and then the sludge pump 51 is used for suction.
