Description

Technical Field

[0001] This invention belongs to the field of urban pipeline cleaning technology, and specifically relates to a municipal drainage and sewage pipeline cleaning device. Background Technology

[0002] There are various underground pipes in the city, among which sewage pipes are an important support for ensuring the cleanliness of the city. However, after years of use, they can become blocked or accumulate sediment; therefore, regular sewage cleaning is necessary.

[0003] After searching, a device for treating sludge inside a pipe for urban pipelines with application number 202020092502.2 was found. The device is equipped with a discharge head and a rotating drum, which are spirally connected and can be disassembled and replaced to suit pipes of different diameters.

[0004] However, there are also obvious drawbacks in the use of this device. For example, if the pipe diameter changes when the sewage head has already traveled deep into the pipe, the entire treatment device must be moved out of the city pipeline to replace the sewage head. This process of moving the treatment device out to replace the sewage head greatly reduces work efficiency and delays the construction period.

[0005] Meanwhile, if there are other obstructions besides sludge in the city's pipelines, such as tree branches, the process of collecting sludge in front of the sewage head will be greatly affected, including the operation of the water pump. It will also be difficult to discharge larger tree branches; the tree branches need to be chopped up to be discharged at the same time as the sludge. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a municipal drainage and sewage pipe cleaning device that can not only adapt to pipes of different diameters by controlling the opening and closing of the arc plate, but also has a cutting mechanism that can cut off obstacles in front of the sewage discharge mechanism to ensure the smooth discharge of sewage.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A municipal drainage and sewage pipe cleaning device includes a shell, a power mechanism, a sewage discharge mechanism, a support mechanism, a cutting mechanism, a conveying mechanism, a hydraulic oil station, a gasoline generator set, and a suction mechanism. The power mechanism is fixed at one end of the shell, the sewage discharge mechanism is located on one side of the power mechanism, the support mechanism and the cutting mechanism are located on one side of the sewage discharge mechanism and connected to the power mechanism, and the conveying mechanism is located at the bottom of the power mechanism and connected to the shell and the sewage discharge mechanism respectively. The hydraulic oil station, the gasoline generator set, and the suction mechanism are located inside the shell, and the suction mechanism is connected to the conveying mechanism. The hydraulic oil station is connected to the power mechanism through an oil pipe. The gasoline generator set is located on one side of the hydraulic oil station. The power mechanism is connected to the hydraulic oil station through an oil circuit.

[0009] Inside the housing, a suction mechanism I is located on one side of the hydraulic oil station. This mechanism includes a suction pump I with a telescopic suction pipe. One end of the telescopic suction pipe passes through the housing and has a suction port. The telescopic suction pipe extends and retracts, causing the suction port to adapt to the inner diameter of the pipe. A traveling mechanism is located around the outer perimeter of the housing. This mechanism includes a support leg and a hydraulic cylinder I. One end of the support leg is hinged to the outer wall of the housing, the base of the hydraulic cylinder I is hinged to the outer wall of the housing, and the top shaft of the hydraulic cylinder I is hinged to the support leg. The support leg is equipped with a hydraulic motor I and rollers. The output shaft of the hydraulic motor I and the roller shaft are equipped with sprockets and connected by a chain. Hydraulic motor I and cylinder I are connected to a hydraulic power station via an oil circuit. Hydraulic motor I drives the rollers to rotate, causing the housing to move. The movement of the housing is controlled by a traveling mechanism, and cylinder I controls the opening or retraction of the support legs to adapt to the inner diameter of the pipe. The hydraulic power station provides power to the power mechanism, which drives the support mechanism and the cutting mechanism to rotate and cut or shred larger obstructions in the pipe. The sewage discharge mechanism collects sewage during the movement and discharges the blockage or deposited sewage through a conveying mechanism in conjunction with a suction mechanism. A gasoline generator set supplies power to the electrical components.

[0010] The power mechanism includes a housing, a main shaft, and a hydraulic motor II. One end of the housing is fixedly connected to the other end of the casing. The hydraulic motor II is located inside the housing, and the main shaft is mounted on the hydraulic motor II and passes through the side wall of the housing. One end of the main shaft is provided with a conical cover and a key block. The conical cover is used to reduce resistance. The hydraulic motor II drives the main shaft to rotate. One end of the housing is provided with a fixed plate and a pressure plate. The pressure plate is fixed by inserting bolts into the through holes on the fixed plate and cooperating with nuts. The fixed plate and the pressure plate form a T-shaped sliding groove.

[0011] The sewage discharge mechanism includes a fixed plate I, a pull ring, an arc-shaped plate, a connecting plate, and hydraulic cylinders. The fixed plate I is fixedly connected to the main shaft. A protective cover II is provided on one side of the fixed plate I. Several evenly distributed guide blocks are provided on the periphery of the fixed plate I. Several evenly distributed T-shaped columns are provided on the other side of the fixed plate I and are positioned within a T-shaped groove at one end of the housing for auxiliary support. The pull ring is sleeved onto the fixed plate I. Several guide grooves are provided on the pull ring and fit into the guide blocks. A T-shaped groove is provided on one side of the pull ring. A pair of hydraulic cylinders are provided on both sides of the housing. A slider is provided on the cylinder top shaft and is movably connected to a pull ring in a T-slot. The pull ring is pulled along the guide block by a hydraulic cylinder. Several arc-shaped plates are provided, and one end of the arc-shaped plate is hinged to a fixed plate I. A connecting rod is provided on the pull ring, and the two ends of the connecting rod are respectively hinged to the pull ring and the arc-shaped plate. A connecting plate is provided between adjacent arc-shaped plates. The connecting plate is formed by hinged connection of baffle plates. According to the actual situation, it can be formed by hinged connection of multiple baffle plates. The pull ring is pulled by the hydraulic cylinder, thereby causing the arc-shaped plates to open or close. The connecting plate is used to seal the gap between adjacent arc-shaped plates.

[0012] The arc-shaped plate is provided with a drain outlet and a sealing plate. The drain outlet has an installation groove, and the sealing plate is placed in the installation groove. The arc-shaped plate has storage grooves on both sides for setting up connecting plates. One side of the arc-shaped plate is provided with a sliding groove I, a sliding groove II, a telescopic column, and a spring I. One end of the sealing plate is provided with a guide column and a fixing block. The guide column is placed in the sliding groove II, and the fixing block is placed in the sliding groove I. The spring I is sleeved on the telescopic column. One end of the telescopic column is fixedly connected to the fixing block, and the other end is fixedly connected to the top block fixedly provided on the arc-shaped plate. The other side of the arc-shaped plate is provided with an arc-shaped baffle. The drain outlet side of the arc-shaped plate is provided with a through hole I. When the sealing plate slides along the installation groove, it squeezes out any dirt that may exist in the installation groove and discharges it through the through hole I.

[0013] The conveying mechanism includes a through pipe I and a through pipe II; a support frame is provided on one side of through pipe I and is fixed to the bottom of the box by the support frame; through pipe II is inserted into through pipe I; a top plate I, a guide shaft, and a spring II are provided on both sides of through pipe I, and a top plate II is provided on both sides of through pipe II. A support plate is provided at the end of through pipe II, and a guide groove I is provided on the support plate; the end of through pipe II is larger than the drain outlet; one end of the guide shaft is fixedly connected to the top plate I, and the other end passes through the top plate II and is slidably connected; the spring II is sleeved on the guide shaft; when the arc plate is expanded by the oil cylinder, it will press through pipe II to slide inside through pipe I; when the arc plate contracts, the spring II pushes through pipe II to return to its original position.

[0014] During sewage discharge, the hydraulic cylinder controls the pull ring to move along the guide block, which in turn pulls the arc plate to open or close to adapt to the inner diameter of the pipe via a connecting rod. Then, the traveling mechanism controls the movement of the housing, collecting the sewage in the pipe into the arc plate. During this process, the hydraulic motor II drives the main shaft to rotate, which in turn drives the fixed plate I to rotate, thereby driving the arc plate to rotate. When the arc plate rotates to the conveying mechanism, the guide column enters the guide groove I. As the arc plate continues to rotate, the guide column drives the sealing plate to slide along the slide groove II, thereby opening the sewage outlet. At this time, the sewage outlet connects to the port of the connecting pipe II. Since the port of the connecting pipe II is larger than the sewage outlet, the guide groove I is set here to... When the drain outlet is fully inside the pipe II port, the guide post enters the guide groove I and gradually opens the drain outlet to prevent premature opening and leakage. Dirt on the arc plate enters the conveying mechanism through the drain outlet, and the arc-shaped baffle on the arc plate facilitates its entry into the drain outlet. When the guide post disengages from the guide groove I, spring I pushes the sealing plate to reset and close the drain outlet to prevent leakage. Then, the suction mechanism removes the dirt from the conveying mechanism. This draining mechanism can handle draining work on pipes of different diameters, avoiding the drawback of needing to replace the drain head in ordinary draining devices.

[0015] The support mechanism includes a fixed disk II, a support arm I, a support arm II, an electric push rod I, and an electric push rod II. The fixed disk II has a keyway that meshes with a key block on the main shaft to form a spline structure. The support arms I and II are hollow. There is a pair of support arms I located on both sides of the fixed disk II, and a pair of support arms II located inside the support arms I. The electric push rod I is fixed inside the support arm I, and its top shaft is fixedly connected to the support arm II. The top of the support arm II is equipped with a cutter I. A protective cover I is provided on one side of the fixed disk II. The protective cover I is fitted onto the protective cover II. The electric push rod II is located inside the protective cover I and is fixed to the fixed disk I. Its top shaft is fixedly connected to the fixed disk II, and the electric push rod II drives the fixed disk II to move along the main shaft.

[0016] The cutting mechanism includes a fixed plate III, a cutter II, and a cutter III; the fixed plate III is fixed to the end of the main shaft, one end of the cutter II is hinged to the fixed plate III, one end of the cutter III is hinged to the support arm II, and one end of the cutter II is sleeved on one end of the cutter III.

[0017] The rotation of the main shaft drives the cutting mechanism and the support mechanism to rotate simultaneously; the cutter III and cutter II cut the obstructing dirt in the pipe; the cutter I cuts the dirt attached to the inner wall of the pipe; according to the resistance of the obstruction, the electric push rod II controls the movement of the fixed plate II along the main shaft, thereby controlling the inclination of the cutter II and cutter III to adapt to the cutting resistance; then the electric push rod I controls the support arm II to rise and fall along the support arm I, thereby driving the cutter II and cutter III to extend and retract to adapt to different pipe inner diameters.

[0018] The suction mechanism includes a suction pipe, a drain pipe, and a suction pump II. The suction pump II is fixed on the inner wall of the housing. One end of the suction pipe is connected to the suction pump II, and the other end is connected to the through pipe I. One end of the drain pipe is connected to the suction pump II.

[0019] Preferably, the housing is equipped with a camera and an external display for observing the sewage discharge situation inside the pipe, and the display is located in an external control room.

[0020] The advantages of this invention compared to existing technologies are as follows:

[0021] 1) During sewage discharge, the hydraulic cylinder controls the pull ring to move along the guide block, which in turn pulls the arc plate to open or close to adapt to the inner diameter of the pipe via a connecting rod. Then, the traveling mechanism controls the movement of the housing to collect the sewage in the pipe into the arc plate. During this process, the hydraulic motor II drives the main shaft to rotate, which in turn drives the fixed plate I to rotate, thereby driving the arc plate to rotate. When the arc plate rotates to the conveying mechanism, the guide column enters the guide groove I. As the arc plate continues to rotate, the guide column drives the sealing plate to slide along the slide groove II, thereby opening the sewage outlet. At this time, the sewage outlet connects to the port of the connecting pipe II. Since the port of the connecting pipe II is larger than the sewage outlet, the guide groove I set here allows the sewage outlet to completely open. When the entire pipe enters the II port, the guide post enters the guide groove I and gradually opens the drain port to prevent premature opening and leakage. Dirt on the arc plate enters the conveying mechanism through the drain port, and the arc-shaped baffle on the arc plate facilitates its entry into the drain port. When the guide post disengages from the guide groove I, spring I pushes the sealing plate to reset and close the drain port to prevent leakage. Then, the suction mechanism removes the dirt from the conveying mechanism. This drainage mechanism can handle drainage work for pipes of different diameters, avoiding the drawback of ordinary drainage devices requiring complete removal from the city pipeline and replacement of the drain head.

[0022] 2) This invention is equipped with a cutting mechanism, which drives the cutting mechanism and the support mechanism to rotate simultaneously through the rotation of the main shaft; the cutter III and cutter II cut the obstructing dirt in the pipe; the cutter I cuts the dirt attached to the inner wall of the pipe; according to the resistance of the obstruction, the fixed plate II is moved along the main shaft by the electric push rod II, thereby controlling the inclination of the cutter II and cutter III to adapt to the cutting resistance; then the support arm II is raised and lowered along the support arm I by the electric push rod I, thereby driving the cutter II and cutter III to extend and retract to adapt to different pipe inner diameters.

The sewage discharge mechanism 3 collects sewage during the movement and discharges the blocked or deposited sewage through the conveying mechanism 6 in conjunction with the suction mechanism 9. The gasoline generator set 8 supplies power to the electrical components.

[0042] The power mechanism 2 includes a housing 203, a main shaft 201, and a hydraulic motor II 202. One end of the housing 203 is fixedly connected to one end of the housing 1. The hydraulic motor II 202 is located inside the housing 203. The main shaft 201 is mounted on the hydraulic motor II 202 and passes through the side wall of the housing 203.

[0043] The sewage discharge mechanism 3 includes a fixed plate I 301, a pull ring 302, an arc plate 303, a connecting plate 304, and a hydraulic cylinder 305. The fixed plate I 301 is fixedly connected to the main shaft 201. A protective cover II 3013 is provided on one side of the fixed plate I 301.

A T-shaped groove 3023 is provided on one side of the pull ring 302. The T-shaped groove 3023 can also be set by a fixed plate and a pressure plate. A pair of hydraulic cylinders 305 are provided. Located on both sides of the housing 203, the top shaft of the hydraulic cylinder 305 is equipped with a slider and is movably connected to the pull ring 302 in the T-slot 3023. The pull ring 302 is pulled by the hydraulic cylinder 305 to slide along the guide block 3011. Several arc-shaped plates 303 are provided, and one end of the arc-shaped plate 303 is hinged to the fixed disk I 301. The pull ring 302 is provided with a connecting rod 3022, and the two ends of the connecting rod 3022 are respectively hinged to the pull ring 302 and the arc-shaped plate 303. The connecting plate 304 is provided between adjacent arc-shaped plates 303. The connecting plate 304 is formed by hinged connection through the baffle plate 3041. According to the actual situation, it can be formed by hinged connection of multiple baffle plates 3041. The hydraulic cylinder 305 pulls the pull ring 302, thereby driving the arc-shaped plate 303 to open or close. The connecting plate 304 is used to seal the gap between adjacent arc-shaped plates 303.

[0044] The arc-shaped plate 303 is provided with a drain outlet 3031 and a sealing plate 3033. A mounting groove 306 is provided at the drain outlet 3031, and the sealing plate 3033 is disposed within the mounting groove 306. Storage grooves 3032 are provided on both sides of the arc-shaped plate 303 for mounting connecting plates 304. One side of the arc-shaped plate 303 is provided with a sliding groove I 3034, a sliding groove II 3038, a telescopic column 3035, and a spring I 3036. One end of the sealing plate 3033 is provided with a guide column 30331 and a fixing block 30332. The guide column 30331 is disposed within the sliding groove II 3038. The fixing block 30332 is located in the sliding groove I 3034; the spring I 3036 is sleeved on the telescopic column 3035, one end of the telescopic column 3035 is fixedly connected to the fixing block 30332, and the other end is fixedly connected to the top block fixed on the arc plate 303; the other side of the arc plate 303 is provided with an arc baffle 3039; the arc plate 303 has a through hole I 3037 on one side of the drain outlet 3031, when the sealing plate 3033 slides along the mounting groove 306, it squeezes out the dirt that may exist in the mounting groove 306 and discharges it through the through hole I 3037.

[0045] The conveying mechanism 6 includes a through pipe I 601 and a through pipe II 602; a support frame 6014 is provided on one side of the through pipe I 601 and is fixed to the bottom of the box 203 by the support frame 6014; the through pipe II 602 is inserted into the through pipe I 601; the through pipe I 601 is provided with a top plate I 6011, a guide shaft 6012, and a spring II 6013 on both sides; the through pipe II 602 is provided with a top plate II 6022 on both sides; a support plate 6021 is provided at the end of the through pipe II 602, and a guide shaft 6021 is provided on the support plate 6021. The guide shaft 6012 is fixedly connected to the top plate 6011 at one end and passes through the top plate 6022 and is slidably connected at the other end. The spring 6013 is sleeved on the guide shaft 6012. When the arc plate 303 is pulled by the oil cylinder 305 to expand, it will press the passage pipe 602 to slide in the passage pipe 601. When the arc plate 303 contracts, the spring 6013 pushes the passage pipe 602 to reset.

[0046] During sewage discharge, the hydraulic cylinder 305 controls the pull ring 302 to move along the guide block 3011, which in turn pulls the arc plate 303 to open or close to adapt to the inner diameter of the pipe 11 via the connecting rod 3022. Then, the traveling mechanism 102 controls the movement of the housing 1 to collect the sewage in the pipe 11 into the arc plate 303. During this process, the hydraulic motor II 202 drives the main shaft 201 to rotate, which in turn drives the fixed disk I 301 to rotate, thereby driving the arc plate 303 to rotate. When the arc plate 303 rotates to the conveying mechanism 6, the guide column 30331 enters the guide groove I 60211. As the arc plate 303 continues to rotate, the guide column 30331 drives the sealing plate 3033 to slide along the sliding groove II 3038, thereby opening the sewage outlet 3031. At this time, the sewage outlet 3031 connects to the port of the connecting pipe II 602. Since the port of the connecting pipe II 602 is larger than the sewage outlet 3031, the guide is set here. When the drain outlet 3031 is fully inserted into the port of the pipe 602, the guide post 30331 enters the guide groove 60211 and gradually opens the drain outlet 3031, preventing premature opening of the drain outlet 3031 and leakage. The dirt on the arc plate 303 enters the conveying mechanism 6 through the drain outlet 3031, and the arc baffle 3039 on the arc plate 303 makes the dirt on the arc plate 303 enter the drain outlet 3031 more smoothly. When the guide post 30331 is disengaged from the guide groove 60211, the spring 3036 pushes the sealing plate 3033 to reset and close the drain outlet 3031 to prevent dirt from leaking through the drain outlet 3031. Then, the suction mechanism 9 removes and transfers the dirt in the conveying mechanism 6. The above-mentioned draining mechanism 3 can handle the draining work of pipes 11 with different diameters, avoiding the disadvantage of ordinary draining devices that require replacement of the drain head.
