Description

Technical Field

[0001] This utility model belongs to the field of pipeline dredging technology, specifically relating to a pipeline dredging device for municipal engineering. Background Technology

[0002] In the municipal engineering system, pipeline dredging refers to the use of physical, chemical, or mechanical means to remove accumulated dirt, debris, and blockages from municipal drainage and sewage pipes, restoring unobstructed flow and ensuring the normal operation of the urban drainage system. With the rapid development of urban construction, municipal pipelines play an important role in transporting domestic sewage, rainwater, and industrial wastewater. However, during long-term use, pipelines are prone to blockages due to grease buildup, silt deposition, accumulation of domestic waste, and tree root intrusion. If pipeline blockages cannot be cleared in time, they can lead to sewage overflows, urban flooding, and other problems that affect residents' normal lives. They can also cause serious consequences such as environmental pollution and damage to pipeline structures. Therefore, pipeline dredging has become an indispensable part of maintaining the normal operation of municipal infrastructure.

[0003] Traditional pipe cleaning devices are mostly simple in structure and have many limitations. For example, some devices cannot be adjusted for pipes with different inner diameters, requiring operators to frequently change different sizes of equipment, resulting in low work efficiency. Some devices rely on only a single cleaning method, such as simple mechanical scraping or water flushing, which is difficult to deal with complex blockages and is not effective in cleaning stubborn dirt or large blockages. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a pipe dredging device for municipal engineering, which solves the problems of traditional pipe dredging devices having a simple structure, being unable to be used with pipes of different inner diameters, and having a single dredging method and low efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe dredging device for municipal engineering, comprising an installation plate, an installation cylinder fixed at the center of one end of the installation plate, an installation seat fixed at the end of the cylinder, an installation ring rotatably sleeved on the outer side of the installation seat, and a plurality of movable through holes equidistantly arranged around the installation ring, the movable through holes being arc-shaped and one end of the movable through holes inclined toward the center of the installation ring, the movable through holes being connected to limiting components arranged on the outer side of the installation seat, and six sets of limiting components being arranged, each limiting component including a movable rod that movably passes through the movable through holes, and movable plates being installed at both ends of the movable rod, each movable plate having a limiting plate fixed at its end, the limiting plates being respectively connected to bristles, scrapers, and nozzles, an adjustment component provided at one end of the installation plate being connected to the installation ring, the adjustment component including a motor, the motor being fixed at one end of the installation plate, and a gear mounted on the output shaft of the motor engaging with a plurality of toothed blocks arranged around the curved side of the installation ring.

[0006] The beneficial effects of this utility model are:

[0007] Through the cooperation of motor one, gear one and mounting ring, the mounting ring is driven to rotate. Utilizing the unique design of the arc-shaped movable through hole and limiting component on the mounting ring, the movable rod, under the thrust of the movable through hole and the guidance of the limiting slide groove, drives the brush bristles, scraper and nozzle to move radially along the pipeline. It can be adapted to municipal pipelines with different inner diameters, increasing the applicability of the device.

[0008] The device employs a combined approach to unblocking pipes, utilizing pulverizing, scraping, and rinsing. Motor 2 drives the mounting base to rotate, causing the pulverizing fan to pre-treat large blockages within the pipes with its serrated edge structure. High-strength nylon bristles loosen the dirt, while the curved-blade scraper removes stubborn stains. Finally, the nozzle sprays high-pressure water to rinse away any remaining impurities. These three elements work together to clean the pipe's inner wall from different angles, effectively removing various types of dirt and achieving deep cleaning. Compared to traditional single-method unblocking techniques, the cleaning effect is significantly improved.

[0009] To accommodate pipes of different inner diameters:

[0010] As a further improvement to the above technical solution: the ends of the fixing plates are fixed on both sides of the mounting base, and a limiting groove is opened on the opposite side of the two sets of fixing plates. A slider is slidably fitted in the limiting groove, and the slider is fixed on the bottom end of the movable plate facing the fixing plate.

[0011] The beneficial effects of this improvement are as follows: the fixed plate is fixed at both ends of the mounting base and is equipped with a limiting groove that cooperates with the slider, so that the movable plate can slide along a specific direction under the action of the limiting component, so that the limiting plate drives the brush bristles, scraper and nozzle to move radially along the pipeline, adjust the distance and fit with the inner wall of the pipeline, and increase the applicability of the device.

[0012] To efficiently clean different types of dirt from the inner walls of pipes:

[0013] As a further improvement to the above technical solution: two brush bristles, scraper, and nozzle are provided, and the two brush bristles, scraper, and nozzle are symmetrically mirrored about the center line of the mounting base. The brush bristles are made of high-strength nylon material, and the scraping surface of the scraper is set as an arc-shaped cutting edge.

[0014] The beneficial effects of this improvement are as follows: after the brush bristles initially loosen the dirt and the scraper removes stubborn stains, the high-pressure water jet from the nozzle can further rinse the inner wall of the pipe, thoroughly flushing away the remaining dirt, debris and other impurities from the inner wall of the pipe. The three work together to achieve efficient cleaning of different types of dirt on the inner wall of the pipe.

[0015] In order to deliver the liquid water into the cavity inside the mounting cylinder:

[0016] As a further improvement to the above technical solution: the mounting cylinder is set with a cavity, and a water injection pipe is rotatably installed through the cavity at one end of the mounting cylinder facing the mounting plate. A dynamic sealing ring is provided at the connection between the water injection pipe and the mounting cylinder. One end of the water injection pipe passes through the mounting plate and is fixedly connected to it. One end of the water injection pipe is connected to a water pump set at the other end of the mounting plate. The suction pipe set at one end of the water pump passes through a liquid storage tank fixed at the other end of the mounting plate and is fixedly connected to it.

[0017] The beneficial effect of this improvement is that the water in the storage tank is transported to the cavity inside the mounting cylinder through the water injection pipe.

[0018] For deep cleaning of pipes:

[0019] As a further improvement to the above technical solution: the limiting plate connected to the nozzle has an internal cavity, and the nozzle passes through the internal cavity of the limiting plate. One end of the connecting hose passes through the side of the limiting plate opposite to the nozzle, and the other end of the hose passes through both sides of the mounting cylinder away from the mounting plate and is fixedly connected thereto. A waterproof sealing joint is provided at the connection between the limiting plate and the hose.

[0020] The beneficial effects of this improvement are as follows: the water in the storage tank is delivered to the nozzle through the water injection pipe and hose, which powerfully flushes the inside of the pipe, effectively removing mud, sand, debris and other impurities, as well as the residue after cleaning with the brush and scraper, achieving deep cleaning of the pipe and improving the cleaning ability of the unblocking device.

[0021] To improve cleaning effectiveness:

[0022] As a further improvement to the above technical solution: the other end of the mounting plate is connected to both ends of the fixing seat, one side of the fixing seat is connected to the output shaft of the second motor, the second motor is fixed to one end of the mounting rod, and the other end of the mounting rod is provided with a handle. A pulverizing fan is fixed at the center of the end of the mounting seat facing away from the mounting cylinder, and the edge of the pulverizing fan is provided with a serrated structure.

[0023] The beneficial effects of this improvement are: by driving the second motor to rotate the mounting base through the fixed base, the pulverizing fan, brush, scraper, and nozzle make circular motions around the inner wall of the pipe, thus improving the cleaning effect.

[0024] In order to unify the control of this device:

[0025] As a further improvement to the above technical solution: a controller is fitted into one side of the handle, and the controller is equipped with a microcontroller, a relay, and a control switch. The controller is electrically connected to motor one, motor two, and water pump.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, a pipe dredging device for municipal engineering includes a mounting plate 1. A mounting cylinder 11 is fixed at the center of one end of the mounting plate 1, and a mounting seat 3 is fixed at its end. A mounting ring 2 is rotatably sleeved on the outer side of the mounting seat 3. The mounting ring 2 has several equidistant movable through holes 201 around its perimeter. Each movable through hole 201 is arc-shaped, and one end of each movable through hole 201 is inclined towards the center of the mounting ring 2. The movable through holes 201 are connected to a limiting component 13 disposed on the outer side of the mounting seat 3. The limiting component 13 has six sets, and each limiting component 13 includes a movable rod 13. 03, the movable rod 1303 movably passes through the movable through hole 201, and movable plates 1302 are installed at both ends of the movable rod 1303. Limiting plates 6 are fixed at the ends of the movable plates 1302. The limiting plates 6 are respectively connected to the brush bristles 7, the scraper 8, and the nozzle 9. The adjusting component 5 provided at one end of the mounting plate 1 is connected to the mounting ring 2. The adjusting component 5 includes a motor 501. The motor 501 is fixed at one end of the mounting plate 1, and the gear 502 installed on the output shaft of the motor 501 meshes with several tooth blocks arranged around the curved side of the mounting ring 2.

[0037] The ends of the fixed plates 1301 are fixed to both sides of the mounting base 3, and each of the two sets of fixed plates 1301 has a limiting groove on its opposite side. A slider is slidably fitted into the limiting groove, and the slider is fixed to the bottom end of the movable plate 1302 facing the fixed plate 1301. The ends of the fixed plates 1301 are fixed to both sides of the mounting base 3 and are provided with limiting grooves to cooperate with the sliders, so that the movable plate 1302 can slide along a specific direction under the action of the limiting component 13, so that the limiting plate 6 drives the brush bristles 7, scraper 8, and nozzle 9 to move radially along the pipe, adjusting the distance and fit with the inner wall of the pipe, thus increasing the applicability of the device.

[0038] Two brush bristles 7, scraper 8, and nozzle 9 are provided, and the two brush bristles 7, scraper 8, and nozzle 9 are symmetrically mirrored with respect to the center line of the mounting base 3. The brush bristles 7 are made of high-strength nylon material, and the scraping surface of the scraper 8 is set with an arc-shaped cutting edge. After the brush bristles 7 initially loosen the dirt and the scraper 8 removes stubborn stains, the high-pressure water jet from the nozzle 9 can further rinse the inner wall of the pipe, completely flushing away the residual dirt, debris, and other impurities from the inner wall of the pipe. The three work together to achieve efficient cleaning of different types of dirt on the inner wall of the pipe.

[0039] The mounting cylinder 11 is hollow. A water injection pipe is rotatably installed through the cavity at one end of the mounting cylinder 11 facing the mounting plate 1. A dynamic sealing ring is provided at the connection between the water injection pipe and the mounting cylinder 11. One end of the water injection pipe passes through the mounting plate 1 and is fixedly connected to it. The other end of the water injection pipe is connected to a water pump 15 installed at the other end of the mounting plate 1. A suction pipe installed at one end of the water pump 15 passes through a liquid storage tank 14 fixed at the other end of the mounting plate 1 and is fixedly connected to it. Water in the liquid storage tank 14 is transported to the cavity inside the mounting cylinder 11 through the water injection pipe.

[0040] The limiting plate 6 connected to the nozzle 9 has an internal cavity, and the nozzle 9 penetrates through the internal cavity of the limiting plate 6. One end of the connecting hose 12 is passed through the side of the limiting plate 6 opposite to the nozzle 9. The other end of the hose 12 passes through both sides of the mounting cylinder 11 away from the mounting plate 1 and is fixedly connected to it. A waterproof sealing joint is provided at the connection between the limiting plate 6 and the hose 12. Water in the storage tank 14 is transported to the nozzle 9 through the water injection pipe and the hose 12 to powerfully flush the inside of the pipe, effectively removing mud, sand, debris and other impurities from the pipe, as well as the residue after cleaning with the brush 7 and scraper 8, achieving deep cleaning of the pipe and improving the cleaning ability of the unblocking device.

[0041] The other two ends of the mounting plate 1 are connected to the two ends of the fixing base 101. One side of the fixing base 101 is connected to the output shaft of the second motor 10. The second motor 10 is fixed to one end of the mounting rod, and the other end of the mounting rod is provided with a handle 102. The center of the end of the mounting base 3 facing away from the mounting cylinder 11 is fixed with a pulverizing fan 4, and the edge of the pulverizing fan 4 is provided with a serrated structure. By driving the second motor 10, it drives the mounting base 3 to rotate through the fixing base 101, so that the pulverizing fan 4, brush bristles 7, scraper 8, and nozzle 9 make circumferential motion around the inner wall of the pipe, which improves the cleaning effect.

[0042] A controller is fitted into one side of the handle 102, and the controller contains a microcontroller, a relay, and a control switch. The controller is electrically connected to motor 1 501, motor 2 10, and water pump 15.

[0043] The working principle and usage process of this utility model: The operator holds the handle 102 and moves the device to the municipal pipeline to be dredged. The device is started by the control switch in the controller. At this time, the microcontroller starts to run the preset program, and the relay controls the motor 1 501, the motor 2 10 and the water pump 15 to be in standby mode. Check the water level in the storage tank 14 to ensure sufficient water for rinsing. If the water level is insufficient, replenish it promptly. Insert the device into the pipe. The user first drives the motor 501, causing its output shaft to drive the gear 502 to rotate. Since the gear 502 meshes with several toothed blocks arranged around the curved side of the mounting ring 2, the rotation of the gear 502 will drive the mounting ring 2 to rotate circumferentially around the outside of the mounting base 3. When the mounting ring 2 rotates, the inner wall of the arc-shaped movable through hole 201 will generate a thrust on the movable rod 1303 along its arc-shaped trajectory. Under the limiting and guiding action of the limiting slide groove on the movable plate 1302, the movable rod 1303 cannot make a simple circular motion with the mounting ring 2. It can only drive the movable plate 1302 to slide along the direction of the limiting slide groove under the constraint and thrust of the movable through hole 201. This causes the limiting plate 6 fixed at the end of the movable plate 1302 and the limit plate 6 connected to the limiting plate 1302 to move along the direction of the limiting slide groove. The brush bristles 7, scraper 8, and nozzle 9 on plate 6 move radially along the pipe to adapt to pipes of different inner diameters. Then, the drive motor 10 drives the mounting base 3 to rotate as a whole through the fixed base 101. At this time, the pulverizing fan 4 pulverizes large blockages in the pipe. The serrated edge structure enhances the cutting efficiency. At the same time, the rotation of the mounting base 3 drives the brush bristles 7, scraper 8, and nozzle 9, which have been adjusted to the appropriate position, to make a circular motion around the inner wall of the pipe. The operator starts the water pump 15. The water in the storage tank 14 enters the water pump 15 through the suction pipe, and then is delivered to the nozzle 9 through the water injection pipe and hose 12. The nozzle 9 sprays high-pressure water precisely onto the inner wall of the pipe, thoroughly flushing away residual dirt, debris, and other impurities. Combined with the residue cleaned by the brush bristles 7 and scraper 8, a deep cleaning of the pipe is achieved.
