Description

Technical Field

[0001] This invention relates to the field of pipeline dredging technology, and in particular to a dredging device for preventing silt blockage in water supply and drainage pipe networks. Background Technology

[0002] As a core component of urban infrastructure, water supply and drainage networks undertake crucial functions such as sewage discharge, rainwater collection and drainage, and industrial water transportation. Their smooth operation directly impacts urban drainage safety and residents' daily lives. Over long-term use, silt, debris, sand, and sticky dirt easily accumulate inside the pipes, gradually forming blockages. This leads to reduced drainage efficiency, localized waterlogging, and sewage backflow, and in severe cases, can cause road subsidence, environmental pollution, and other safety hazards. Therefore, regular dredging and cleaning of water supply and drainage networks is essential maintenance to ensure their normal operation.

[0003] However, conventional dredging equipment is mostly rigid in structure and is difficult to adapt to complex sections of pipe bends. When entering the bend, it is prone to jamming and deviation, and cannot fit the inner wall of the bend to complete the cleaning without dead angles. This results in sludge residue and repeated blockage at the bend, which seriously affects the effect and efficiency of dredging operations and cannot meet the actual needs of refined dredging of pipe networks.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a sludge removal device for preventing silt blockage in water supply and drainage pipe networks. The aim is to solve the problem and improve practical value through this technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a sludge removal device for preventing silt blockage in water supply and drainage pipe networks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sludge removal device for preventing silt blockage in water supply and drainage pipe networks, comprising a support member, and further comprising: Hinged seat one is fixedly installed on the support member; Hinge seat two, one end of which is hinged to hinge seat one, and the other end of which is connected to a cleaning mechanism; A water supply pipe, one end of which is connected to a connecting pipe, and one end of the connecting pipe is connected to a spray pipe, with the spray pipe slidably disposed inside the connecting pipe; A fixing mechanism, installed on the support member, is used to press against the inner wall of the pipe and drive the entire device to move along the pipe; The cleaning mechanism includes a mounting bracket fixedly connected to one side of a hinge seat 2. A motor 2 is fixedly mounted on the hinge seat 2. A rotating shaft is driven and connected to the output end of the motor 2. A slide rod is slidably assembled inside the rotating shaft. A connecting plate is fixedly connected to one end of the slide rod. A cleaning tooth 1 is fixedly connected to one side of the connecting plate. A fixed cylinder is fixedly connected to one side of the mounting bracket. A cleaning tooth 2 is rotatably sleeved on one end of the fixed cylinder and is arranged opposite to the cleaning tooth 1. A drive gear 1 is fixedly sleeved on the rotating shaft. An electric push rod is fixedly mounted on the mounting bracket. A conversion gear is driven and connected to the telescopic end of the electric push rod. The conversion gear meshes with the teeth on the inner wall of the drive gear 1 and the cleaning tooth 2, respectively. An auxiliary mechanism is provided on one side of the connecting tube for periodically squeezing the connecting tube.

[0007] Preferably, the fixing mechanism includes a bidirectional electric push rod fixedly installed on the surface of the support member, the output end of the bidirectional electric push rod is driven and connected to a push block, a bracket is hinged to the surface of the support member, a roller is rotatably provided at one end of the bracket, a bracket is hinged between the bracket and the push block, a motor is fixedly installed on the bracket, and the output end of the motor is driven and connected to the roller.

[0008] Preferably, the rotating shaft has a hollow structure, and a spring is installed inside the rotating shaft. The two ends of the spring abut against the inner wall of the rotating shaft and one end of the slide rod, respectively.

[0009] Preferably, a protective sleeve is provided between the first hinge seat and the second hinge seat.

[0010] Preferably, electromagnet one and electromagnet two are fixedly installed on the opposite surfaces of cleaning tooth one and cleaning tooth two, respectively.

[0011] Preferably, the auxiliary mechanism includes a second drive gear fixedly sleeved on the rotating shaft, the outer wall of the connecting pipe is connected to a cylinder, a piston rod is slidably arranged inside the cylinder, a movable plate is fixedly connected to one end of the piston rod, a protrusion is fixedly connected to the side wall of the conversion gear, and the surface of the movable plate is provided with an inclined surface for sliding cooperation with the protrusion.

[0012] Preferably, a second spring is fitted on the outer wall of the piston rod, and the two ends of the second spring abut against the outer wall of the cylinder and one side of the moving plate, respectively.

[0013] Preferably, a solenoid valve is installed on the outer wall of the connecting pipe, and an angle sensor is installed on the first hinge seat. The angle sensor is signal-connected to the solenoid valve, the second motor, and the electric push rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention drives the first cleaning tooth to rotate in the forward direction while the second cleaning tooth rotates in the reverse direction. The second cleaning tooth performs a secondary scraping of the sludge on the inner wall of the pipe, further improving the cleanliness of the inner wall of the pipe. For areas with firmly adhered sludge on the inner wall of the pipe, the first and second cleaning teeth rotate synchronously in opposite directions. The sludge resistance they experience is in opposite directions, which can keep the overall force of the device balanced and effectively avoid the problem of roller circumferential slippage and device lateral slippage when cleaning stubborn sludge due to excessive resistance on one side.

[0015] 2. This invention uses a bidirectional electric push rod to drive two sets of push blocks to move in opposite directions. The two sets of push blocks push the corresponding bracket two to move. The bracket two simultaneously drives the bracket one to rotate around the surface of the support member, so that the multiple rollers on the bracket one gradually press against the inner wall of the pipe. With the uniform support of the multiple sets of rollers against the inner wall of the pipe, the device is stably fixed inside the pipe and has the basic conditions to move along the inner wall of the pipe. This provides stable installation and movement support for subsequent dredging operations and avoids shaking or displacement of the device during the dredging process.

[0016] 3. When the device moves into the bend section of the pipe, the cleaning teeth one and two always remain in contact with the inner wall of the pipe, and the hinge seat one and hinge seat two are hinged to each other, so that the cleaning mechanism and the support have a degree of freedom of movement that can yaw and swing. The cleaning mechanism can autonomously complete adaptive swing according to the curvature of the bend, thereby ensuring that the device passes through the bend area smoothly and stably, with good bend passability, and can adapt to the cleaning operation requirements of curved pipes.

[0017] 4. This invention uses an electromagnet to drive a cleaning tooth 1, which is slidably mounted inside the rotating shaft via a slide rod, to smoothly move towards a cleaning tooth 2 until the cleaning tooth 1 and cleaning tooth 2 are completely attached and form a sealed structure. This not only enables precise and thorough scraping and cleaning of the inner wall of the bend, but also actively pushes away the silt accumulated inside the bend, effectively solving the problem of incomplete silt removal caused by turbulent water flow and uneven flushing at the bend in conventional dredging operations. In addition, by periodically squeezing the water flow inside the connecting pipe through the piston rod, the conventional water flow sprayed from the nozzle is transformed into a more impactful pulsed water flow. At the same time, the angle sensor outputs a signal to control the solenoid valve to open to a larger flow rate. The pulsed water flow and the increased flow rate of the jet water flow work together to enhance the flushing force and carrying capacity of the silt, thereby strengthening the dredging effect and operation efficiency of the bend section.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] See Figures 1 to 8 As shown, the present invention provides a sludge removal device for preventing silt blockage in water supply and drainage pipe networks, including a support member 1, and further comprising: Hinged seat 2 is fixedly installed on support member 1; Hinged seat 2 3, one end of which is hinged to hinged seat 1 2, and the other end of which is connected to cleaning mechanism 5; Water supply pipe 7, one end of water supply pipe 7 is connected to connecting pipe 8, one end of connecting pipe 8 is connected to spray pipe 9, and spray pipe 9 is slidably disposed inside connecting pipe 8; The fixing mechanism 4 is installed on the support 1 and is used to press against the inner wall of the pipe and drive the entire device to move along the pipe. The cleaning mechanism 5 includes a mounting bracket 57 fixedly connected to one side of the hinge seat 3. A motor 51 is fixedly mounted on the hinge seat 3. The output end of the motor 51 is driven and connected to a rotating shaft 52. A slide rod 53 is slidably assembled inside the rotating shaft 52. A connecting plate 54 is fixedly connected to one end of the slide rod 53. A cleaning tooth 55 is fixedly connected to one side of the connecting plate 54. A fixing cylinder 58 is fixedly connected to one side of the mounting bracket 57. A cleaning tooth 59 is rotatably sleeved on one end of the fixing cylinder 58 and is opposite to the cleaning tooth 55. A drive gear 511 is fixedly sleeved on the rotating shaft 52. An electric push rod 510 is fixedly mounted on the mounting bracket 57. A conversion gear 512 is driven and connected to the telescopic end of the electric push rod 510. The conversion gear 512 meshes with the teeth on the inner wall of the drive gear 511 and the cleaning tooth 59, respectively. It should be noted that, for reference Figures 1 to 5 As shown, after the device is fixed, water is supplied to the inside through the water supply pipe 7. The water flow is delivered to the nozzle 9 through the connecting pipe 8 and continuously sprayed along the inside of the pipe by the nozzle 9. At the same time, the motor 46 in the fixing mechanism 4 is started. The motor 46 drives the roller 43 to rotate, which drives the entire device to move at a constant speed along the extension direction of the pipe. The cleaning mechanism 5 moves synchronously with the device. At this time, the motor 51 in the cleaning mechanism 5 is started. The motor 51 drives the rotating shaft 52 to rotate in the forward direction. The rotating shaft 52 drives the connecting plate 54 and the cleaning tooth 55 to rotate synchronously. Since the nozzle 9 is sleeved between the rotating shaft 52 and the cleaning tooth 55 through the bearing, the rotation of the cleaning tooth 55 will not drive the nozzle 9 to rotate. The cleaning tooth 55 continuously rotates to scrape off the sludge adhering to the inner wall of the pipe, realizing the cleaning of the sludge in the inner wall of the pipe without dead corners. The sludge scraped off by the cleaning tooth 55 falls to the bottom of the pipe and is promptly carried out of the pipe by the water flow sprayed by the nozzle 9, avoiding the accumulation of sludge from hindering the subsequent dredging operation and ensuring the smooth dredging process. While the rotating shaft 52 drives the first cleaning tooth 55 to rotate in the forward direction, the rotating shaft 52 synchronously drives the first driving gear 511 to rotate. The first driving gear 511 drives the conversion gear 512 to rotate synchronously. The conversion gear 512 meshes with the teeth on the inner wall of the second cleaning tooth 59, thereby driving the second cleaning tooth 59 to rotate in the opposite direction. The second cleaning tooth 59 performs secondary scraping of the sludge on the inner wall of the pipe, further improving the cleanliness of the inner wall of the pipe. For areas with firmly adhered sludge on the inner wall of the pipe, the first cleaning tooth 55 and the second cleaning tooth 59 rotate synchronously in opposite directions. The sludge resistance they experience is in opposite directions, which can keep the overall force of the device balanced. This effectively avoids the problem of the roller 43 sliding circumferentially and the device sliding sideways when cleaning stubborn sludge due to excessive resistance on one side, ensuring that the dredging operation is carried out continuously and stably.

[0022] The auxiliary mechanism 6 is located on one side of the connecting pipe 8 and is used to periodically squeeze the connecting pipe 8.

[0023] In an optional embodiment, the fixing mechanism 4 includes a bidirectional electric push rod 41 fixedly mounted on the surface of the support member 1. The output end of the bidirectional electric push rod 41 is driven and connected to a push block 44. A bracket 42 is hinged to the surface of the support member 1. A roller 43 is rotatably provided at one end of the bracket 42. A bracket 45 is hinged between the bracket 42 and the push block 44. A motor 46 is fixedly mounted on the bracket 42. The output end of the motor 46 is driven and connected to the roller 43.

[0024] It should be noted that, for reference Figures 1 to 2 As shown, when performing pipeline dredging operations, the entire device is first placed inside the pipeline to be cleaned. Then, the bidirectional electric push rod 41 in the fixing mechanism 4 is activated. The bidirectional electric push rod 41 drives two sets of push blocks 44 to move in opposite directions. The two sets of push blocks 44 push the corresponding support 45 to move. The support 45 simultaneously drives the support 42 to rotate around the surface of the support member 1, so that the multiple rollers 43 on the support 42 gradually press against the inner wall of the pipeline. With the uniform support of the multiple sets of rollers 43 against the inner wall of the pipeline, the device is stably fixed inside the pipeline and has the basic conditions to move along the inner wall of the pipeline. This provides stable installation and movement support for subsequent dredging operations and avoids shaking or displacement of the device during the dredging process.

[0025] In an optional embodiment, the rotating shaft 52 has a hollow structure, and a spring 56 is installed inside the rotating shaft 52. The two ends of the spring 56 abut against the inner wall of the rotating shaft 52 and one end of the slide rod 53, respectively.

[0026] In an optional embodiment, a protective sleeve 12 is fitted between the hinge seat 2 and the hinge seat 3.

[0027] In an optional embodiment, electromagnet 13 and electromagnet 24 are fixedly installed on the opposite surfaces of cleaning tooth 1 55 and cleaning tooth 2 59, respectively.

[0028] In an optional embodiment, the auxiliary mechanism 6 includes a drive gear 61 fixedly sleeved on the rotating shaft 52, a cylinder 62 connected to the outer wall of the connecting pipe 8, a piston rod 63 slidably disposed inside the cylinder 62, a movable plate 64 fixedly connected to one end of the piston rod 63, a protrusion 65 fixedly connected to the side wall of the conversion gear 512, and an inclined surface for sliding engagement with the protrusion 65 on the surface of the movable plate 64.

[0029] In an optional embodiment, a second spring 66 is sleeved on the outer wall of the piston rod 63, with the two ends of the second spring 66 abutting against the outer wall of the cylinder 62 and one side of the moving plate 64, respectively.

[0030] It should be noted that, for reference Figure 1 , Figure 2 , Figures 6 to 8 As shown, when the device moves into the bend section of the pipe, the cleaning teeth 55 and 59 always remain in contact with the inner wall of the pipe, and the hinge seat 2 and 3 are hinged to each other, so that the cleaning mechanism 5 and the support 1 have a degree of freedom of movement that can swing. The cleaning mechanism 5 can autonomously complete adaptive swing according to the curvature of the bend. At the same time, the water pipe 7 is made of soft pipe, and the connecting pipe 8 and the spray pipe 9 are made of hard pipe, which can ensure that the device passes through the bend area smoothly and has good bend passability, and can adapt to the cleaning operation requirements of bend-type pipes. During the rotation of hinge seat 2 3 relative to hinge seat 1 2, angle sensor 10 monitors and provides feedback on the attitude and rotation status of hinge seat 2 3 in real time. When the device enters the bend position, angle sensor 10 immediately outputs a control signal to shut down motor 2 51 and simultaneously energizes electromagnet 1 13 and electromagnet 2 14, causing them to generate a magnetic force that attracts each other. Under the magnetic drive, electromagnet 1 13 drives cleaning tooth 1 55, which is slidably mounted inside rotating shaft 52 via slide rod 53, to smoothly approach cleaning tooth 2 59 until cleaning tooth 1 55 and cleaning tooth 2 59 are completely attached and form a sealed structure. At this time, motor 2 51 is restarted, and cleaning tooth 1 55 and cleaning tooth 2 59 rotate synchronously after being attached and sealed. This can not only achieve precise and thorough scraping and cleaning of the inner wall of the bend, but also actively push the silt accumulated inside the bend, effectively solving the problem of incomplete silt removal caused by turbulent water flow and uneven flushing at the bend in conventional dredging operations. Furthermore, in the synchronized state where cleaning teeth 55 and 59 are engaged, the electric push rod 510 in the cleaning mechanism 5 is activated. The telescopic end of the electric push rod 510 drives the conversion gear 512 to retract, causing the conversion gear 512 to move to a working position where it meshes with the drive gear 61 in the auxiliary mechanism 6. During the displacement process, the conversion gear 512 synchronously drives the protrusion 65 on one side to move. The protrusion 65 contacts and presses against the inclined surface of the moving plate 64, pushing the moving plate 64 downward. After the protrusion 65 moves above the moving plate 64, the motor 51 drives the rotating shaft 52 to rotate, and the drive gear 61 drives the conversion gear 512 to rotate continuously, causing the conversion gear... The protrusion 65 on wheel 512 periodically contacts and squeezes the moving plate 64. With the elastic reset action of spring 66, the moving plate 64 drives the piston rod 63 to make periodic reciprocating linear motions inside the cylinder 62. The piston rod 63 periodically squeezes the water flow inside the connecting pipe 8, turning the conventional water flow sprayed from the nozzle 9 into a more impactful pulsed water flow. At the same time, the angle sensor 10 outputs a signal to control the solenoid valve 11 to open to a larger flow rate. The pulsed water flow and the increased flow of the jet water flow work together to enhance the flushing force and carrying capacity of the sludge, strengthen the sludge removal effect and work efficiency of the bend section, and solve the problem of blockage caused by sludge accumulation in the water supply and drainage network.

[0031] In an optional embodiment, a solenoid valve 11 is installed on the outer wall of the connecting pipe 8, and an angle sensor 10 is installed on the hinge seat 2. The angle sensor 10 is connected to the solenoid valve 11, the motor 51, and the electric push rod 510.

[0032] Working principle: When the device is used for pipeline dredging, the whole device is first placed inside the pipeline to be cleaned. Then, the bidirectional electric push rod 41 in the fixing mechanism 4 is activated. The bidirectional electric push rod 41 drives the two sets of push blocks 44 to move in opposite directions. The two sets of push blocks 44 push the corresponding support 2 45 to move. The support 2 45 drives the support 1 42 to rotate around the surface of the support member 1, so that the multiple rollers 43 on the support 1 42 gradually press against the inner wall of the pipeline. With the help of the uniform support of the multiple sets of rollers 43 against the inner wall of the pipeline. After the device is fixed, water is supplied to the inside through the water supply pipe 7. The water flows through the connecting pipe 8 to the spray pipe 9, and is continuously sprayed along the inside of the pipe by the spray pipe 9. At the same time, the motor 46 in the fixing mechanism 4 is started. The motor 46 drives the roller 43 to rotate, which drives the entire device to move at a constant speed along the extension direction of the pipe. The cleaning mechanism 5 moves synchronously with the device. At this time, the motor 51 in the cleaning mechanism 5 is started. The motor 51 drives the rotating shaft 52 to rotate in the forward direction. The rotating shaft 52 drives the connecting plate 54 and the cleaning teeth 55 to rotate synchronously. The cleaning teeth 55 continuously rotates to scrape off the silt adhering to the inner wall of the pipe, realizing the cleaning of the silt in the inner wall of the pipe without dead corners. The silt scraped off by the cleaning teeth 55 falls to the bottom of the pipe. The water flow sprayed by the spray pipe 9 carries it out of the pipe in time, avoiding the accumulation of silt and causing obstacles to subsequent dredging operations, and ensuring the smooth dredging process. While the rotating shaft 52 drives the first cleaning tooth 55 to rotate in the forward direction, the rotating shaft 52 synchronously drives the first driving gear 511 to rotate. The first driving gear 511 drives the conversion gear 512 to operate synchronously. The conversion gear 512 meshes with the teeth on the inner wall of the second cleaning tooth 59, thereby driving the second cleaning tooth 59 to rotate in the opposite direction. The second cleaning tooth 59 performs secondary scraping of the sludge on the inner wall of the pipe, further improving the cleanliness of the inner wall of the pipe. For areas with firmly adhered sludge on the inner wall of the pipe, the first cleaning tooth 55 and the second cleaning tooth 59 rotate synchronously in opposite directions. The sludge resistance they experience is in opposite directions, which allows the overall force of the device to remain balanced. When the device moves into the bend section of the pipe, the cleaning teeth 55 and 59 always remain in contact with the inner wall of the pipe, and the hinge seat 2 and 3 are hinged to each other, so that the cleaning mechanism 5 and the support 1 form a degree of freedom of movement that can yaw and swing. The cleaning mechanism 5 can autonomously complete adaptive swing according to the curvature of the bend, ensuring that the device passes through the bend area smoothly and steadily. During the rotation of the second hinge seat 3 relative to the first hinge seat 2, the angle sensor 10 monitors and provides feedback on the attitude and rotation status of the second hinge seat 3 in real time. When the device is detected to have entered the bend position, the angle sensor 10 immediately outputs a control signal to shut down the second motor 51 and simultaneously energizes the first electromagnet 13 and the second electromagnet 14, causing them to generate a magnetic force that attracts each other. Under the magnetic drive, the first electromagnet 13 drives the first cleaning tooth 55, which is slidably mounted inside the rotating shaft 52 via the slide rod 53, to smoothly approach the second cleaning tooth 59 until the first cleaning tooth 55 and the second cleaning tooth 59 are completely attached and form a sealed structure. At this time, the second motor 51 is restarted, and the first cleaning tooth 55 and the second cleaning tooth 59 rotate synchronously after being attached and sealed. This can not only achieve precise and thorough scraping and cleaning of the inner wall of the bend, but also actively push the sludge accumulated inside the bend. Furthermore, in the synchronized state where cleaning tooth 55 and cleaning tooth 59 are engaged, the electric push rod 510 in the cleaning mechanism 5 is activated. The telescopic end of the electric push rod 510 drives the conversion gear 512 to retract, causing the conversion gear 512 to move to a working position where it meshes with the drive gear 61 in the auxiliary mechanism 6. During the displacement process, the conversion gear 512 synchronously drives the protrusion 65 on one side to move. The protrusion 65 contacts and presses against the inclined surface of the moving plate 64, pushing the moving plate 64 downward. After the protrusion 65 moves above the moving plate 64, the motor 51 drives the rotating shaft 52 to rotate, driving the gear 61. The rotating gear 512 is driven to rotate continuously, causing the protrusion 65 on the gear 512 to periodically contact and squeeze the moving plate 64. With the elastic reset action of the spring 66, the moving plate 64 drives the piston rod 63 to make periodic reciprocating linear motions inside the cylinder 62. The piston rod 63 periodically squeezes the water flow inside the connecting pipe 8, turning the regular water flow sprayed from the nozzle 9 into a more impactful pulsed water flow. At the same time, the angle sensor 10 outputs a signal to control the solenoid valve 11 to open to a larger flow rate. The pulsed water flow and the increased flow rate of the jet water flow work together to enhance the flushing force and carrying capacity of the sludge.
