Description

Technical Field

[0001] This utility model belongs to the field of dredging technology, specifically relating to a dredging device for drainage culverts and underground channels. Background Technology

[0002] Culverts and culverts are core components of urban drainage systems, primarily used for transporting rainwater and sewage in underground, concealed environments. Their narrow interiors, dim lighting, and uneven water depths often lead to the accumulation of silt and debris, causing blockages over time. Failure to dredge these culverts promptly can result in poor drainage, urban flooding, and even pipe ruptures and road collapses. A search revealed application number "CN202021345270.3" disclosing "a dredging device for water supply and drainage pipelines," which describes a system where "hydraulic positioning bolts and universal pulleys are used. During operation, the universal pulleys, along with the dredging machine casing and tie rods, form a mobile vehicle to support the suction pump unit, facilitating movement and use, and improving ease of use. Simultaneously, the hydraulic telescopic rod drives the ground anchors to embed into the ground, improving the stability of the device and preventing the mobile vehicle from shifting due to vibrations from the suction pump unit, thus enhancing the device's practicality."

[0003] While this equipment can solve the problem of dredging conventional water supply and drainage pipelines, it has significant shortcomings in special scenarios such as drainage ditches and culverts: 1) The water depth in the culverts and culverts fluctuates greatly, and in some areas the water depth exceeds the tolerance range of the moving parts of the equipment. The existing equipment lacks amphibious mobility and is prone to failure due to excessive water depth, making it unable to enter the work area. 2) The internal height of the culverts and culverts varies, and the thickness of the silt accumulation at the bottom varies greatly. The existing dredging structure cannot flexibly adjust the height, making it difficult to adapt to the dredging needs of different depths. In some areas, dredging is prone to incomplete dredging. 3) In the culverts and culverts, gravel, dead branches and other debris are mixed in with the silt. The existing equipment lacks a targeted anti-clogging structure, and the pipes are prone to blockage during the suction process, which leads to the interruption of dredging. In addition, the culverts and culverts are enclosed spaces, making maintenance operations extremely difficult after blockage.

[0004] Based on this, a dredging device is provided that can adapt to the complex environment of underground channels and culverts, achieve amphibious movement, flexibly adjust the dredging height, and has anti-clogging function. It is the key to solving the current problem of dredging underground channels and culverts and has extremely high practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a dredging device for drainage culverts and underground channels, in order to solve the above-mentioned technical problems.

[0006] This utility model provides a dredging device for drainage culverts and underground channels, including a tracked conveyor, an amphibious assembly, and a dredging, anti-clogging, and height adjustment assembly.

[0007] The tracked conveyor is provided with a connecting plate on top, and a storage box is provided on top of the connecting plate. The amphibious assembly includes a fixed frame disposed on both sides of the storage box. The fixed frame is provided with a plurality of first electric telescopic rods. The bottom of the plurality of first electric telescopic rods is provided with a connecting strip. The bottom of the connecting strip is provided with an airbag. A torque motor is provided on one side of the inner wall of the connecting strip. The output shaft end of the torque motor passes through the connecting strip and is provided with a propeller. The dredging, anti-clogging, and height adjustment assembly includes a connecting pipe sealed to one end of the storage tank. One end of the connecting pipe is sealed to a connector. One end of the connector is equipped with a support box. One end of the support box is equipped with a servo motor. The output shaft of the servo motor passes through the inner wall of the support box and the connector and is equipped with an auger. The bottom of the connector is sealed to a telescopic hose. The bottom of the telescopic hose is sealed to a contact pipe. The outer wall of the contact pipe is equipped with a support frame. The top of the support frame is equipped with two second electric telescopic rods. The outer walls of the two second electric telescopic rods are equipped with reinforcing frames. One end of each of the two reinforcing frames is fixedly connected to the storage tank.

[0008] In one embodiment of this utility model, the ventilation assembly includes an air pump disposed at one end of a fixed frame, a delivery hose sealed to the bottom of the air pump, a one-way valve sealed to the end of the delivery hose, one end of the one-way valve sealed to the airbag, and an electric valve sealed to one end of the airbag.

[0009] In one embodiment of this utility model, the auxiliary component includes a mud pump disposed on the top of the storage tank, one end of the mud pump is sealed and connected to a suction pipe, the end of the suction pipe is sealed and connected to a connector, and the top of the mud pump is sealed and connected to a delivery pipe, the end of the delivery pipe being sealed and connected to the storage tank.

[0010] In one embodiment of this utility model, an asynchronous motor is provided on the top of the support frame, and a drive gear is provided through the output shaft end of the asynchronous motor through the support frame. A driven gear meshes with one side of the drive gear.

[0011] In one embodiment of this utility model, a rotating cylinder is provided inside the driven gear, and a plurality of connecting ropes are provided on the outer wall of the rotating cylinder.

[0012] In one embodiment of this utility model, the other end of the storage box is sealed and connected to an external pipe, one end of the external pipe is sealed and connected to an external connector, one end of each of the two fixing frames is provided with several lights and cameras, the inside of the connecting plate is provided with a storage battery, and a controller is provided at the top corner of the storage box.

[0013] In one embodiment of this utility model, the tracked conveyor, the first electric telescopic rod, the torque motor, the servo motor, the second electric telescopic rod, the electric valve, the mud pump, and the asynchronous motor are all electrically connected to the controller, and the controller is electrically connected to the battery.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1) With its amphibious components, it can be precisely adapted to scenarios with uneven water depth in drainage ditches and culverts. When in use, if the water in the culvert is deep, the controller will open the first electric telescopic rod, which will drive the connecting bar, the airbag at the bottom, and the propeller to move downwards. At the same time, the airbag will be inflated by the ventilation component, allowing the equipment to float stably on the water surface. Then, the torque motor will be started to drive the propeller to rotate and provide power. Combined with the ability of the tracked conveyor to move in waterless or shallow water areas, it can achieve "seamless switching between water and land" in culverts and culverts, solving the problem that existing equipment cannot operate in all areas due to the limitation of water depth. 2) With the installed dredging, anti-clogging, and height adjustment components, the controller can open the second electric telescopic rod to drive the support frame and contact pipe to move up and down, adjusting the distance between the contact pipe and the silt surface. At the same time, the telescopic hose can flexibly extend and retract with the contact pipe, ensuring that the contact pipe can accurately fit the silt layer of different thicknesses, avoiding incomplete dredging due to fixed height. 3) To address the issue of debris easily causing blockages in culverts and culverts, the controller uses auxiliary components to pump sludge through contact pipes and telescopic hoses to the connector. At the same time, the servo motor is started to drive the auger to rotate. The auger can break up small debris in the sludge and push it to the storage box. The remaining sludge is diverted and sucked in through the suction pipe of the auxiliary components, achieving dual anti-blockage of "breaking and diverting". This avoids blockages that may cause dredging to be interrupted, and eliminates the need for frequent maintenance in closed culverts and culverts, greatly improving dredging efficiency and safety. 4) The equipment is equipped with lighting and cameras that can adapt to the dimly lit environment inside culverts and tunnels. The lighting provides sufficient illumination, and the camera captures the condition of the silt inside in real time and transmits the information to the terminal, which makes it convenient for operators to remotely monitor the dredging progress and environmental conditions. This further adapts to the concealed operation scenarios of culverts and tunnels and reduces the risk of manual entry. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example

[0019] Please see Figure 1-4 A dredging device for drainage culverts and underground channels includes a tracked conveyor 100, an amphibious assembly 200, and a dredging, anti-clogging, and height adjustment assembly 300.

[0020] Please refer to the details. Figure 1The top of the tracked conveyor 100 is provided with a connecting plate 110, and the top of the connecting plate 110 is provided with a storage box 120.

[0021] Please see Figure 3 The amphibious assembly 200 includes a mounting frame 210 disposed on both sides of the storage tank 120. The mounting frame 210 has a plurality of first electric telescopic rods 220 disposed inside. The bottom of the plurality of first electric telescopic rods 220 is provided with a connecting strip 230. The bottom of the connecting strip 230 is provided with an airbag 240. A torque motor 250 is disposed on one side of the inner wall of the connecting strip 230. The output shaft end of the torque motor 250 passes through the connecting strip 230 and is provided with a propeller 260.

[0022] In one specific embodiment, when the device encounters a location with a large amount of water, the controller will open the first electric telescopic rod 220, causing the electric connecting bar 230 and its bottom parts to move downwards. At this time, the controller will inflate the airbag 240 through the ventilation assembly 400, allowing the device to float on the water surface. The controller will then activate the torque motor 250, which will drive the propeller 260 to rotate, thereby providing power to the device so that it can move on the water surface to clear silt. In conjunction with the tracked conveyor 100, the device can achieve an amphibious purpose.

[0023] Please see Figure 1-4 The dredging, anti-blocking, and height adjustment component 300 includes a connecting pipe 310 sealed to one end of the storage tank 120, a connector 320 sealed to one end of the connecting pipe 310, a support box 330 at one end of the connector 320, a servo motor 340 at one end of the support box 330, an auger 350 at one end of the output shaft of the servo motor 340 passing through the inner wall of the support box 330 and the connector 320, a telescopic hose 360 ​​sealed to the bottom of the connector 320, a contact pipe 370 sealed to the bottom of the telescopic hose 360, a support frame 380 on the outer wall of the contact pipe 370, two second electric telescopic rods 390 on the top of the support frame 380, a reinforcing frame 3910 on the outer wall of each of the two second electric telescopic rods 390, and one end of each of the two reinforcing frames 3910 fixedly connected to the storage tank 120.

[0024] In one specific embodiment, the contact pipe 370 facilitates the controller to open the second electric telescopic rod 390 during use. The second electric telescopic rod 390 drives the support frame 380 to move downward. The downward movement of the support frame 380 in turn drives the contact pipe 370 to move downward and contact the mud. When the contact pipe 370 moves downward, the telescopic hose 360 ​​will follow and unfold to achieve height adjustment. At this time, the controller uses the auxiliary component 500 to draw the mud in through the contact pipe 370 and send it to the connector 320 through the telescopic hose 360. The controller then turns on the servo motor 340, which drives the auger 350 to rotate. The auger 350 sends the mud to the storage tank 120 through the connecting pipe 310 for storage. The remaining mud will be sucked in and diverted by the auxiliary component 500 and finally sent to the storage tank 120. This allows the mud to be diverted and moved, and works with the auger 350 to prevent clogging, thereby achieving the purpose of dredging, clogging prevention, and height adjustment.

[0025] Please see Figure 1-2 The ventilation assembly 400 includes an air pump 410 disposed at one end of the fixed frame 210. The bottom of the air pump 410 is sealed and connected to a delivery hose 420. The end of the delivery hose 420 is sealed and connected to a one-way valve 430. One end of the one-way valve 430 is sealed and connected to an airbag 240. One end of the airbag 240 is sealed and connected to an electric valve 440.

[0026] In one specific embodiment, the provided air pump 410 allows the controller to turn on the air pump 410 during use, so that the air pump 410 inflates the airbag 240 through the delivery hose 420 and the one-way valve 430. When it is necessary to return to the ground, the controller will open the electric valve 440 to discharge the gas and reset it using the first electric telescopic rod 220.

[0027] Please see Figure 1 The auxiliary component 500 includes a mud pump 510 disposed on the top of the storage tank 120. One end of the mud pump 510 is sealed and connected to a suction pipe 520. The end of the suction pipe 520 is sealed and connected to a connector 320. The top of the mud pump 510 is sealed and connected to a delivery pipe 530. The end of the delivery pipe 530 is sealed and connected to the storage tank 120.

[0028] In one specific embodiment, the mud pump 510 is provided so that the controller can turn on the mud pump 510 during use. The mud pump 510 generates suction force through the suction pipe 520 to the connector 320 and its bottom parts. Part of the mud is diverted to the connector 320 and the suction pipe 520, and is sucked in by the mud pump 510 and sent to the storage tank 120 through the delivery pipe 530.

[0029] Please see Figure 4An asynchronous motor 600 is installed on the top of the support frame 380. The output shaft of the asynchronous motor 600 passes through the support frame 380 and is equipped with a drive gear 700. A driven gear 800 meshes with one side of the drive gear 700.

[0030] In one specific embodiment, the asynchronous motor 600 is provided so that the controller can turn on the asynchronous motor 600 during use, so that the asynchronous motor 600 drives the drive gear 700 to rotate, which in turn drives the driven gear 800 to rotate, which in turn drives the rotating drum 900 to rotate. The rotation of the rotating drum 900 will drive the connecting rope 1000 to rotate, which will beat the mud and disperse it so that it is easy to suck in.

[0031] Please see Figure 4 The driven gear 800 has a rotating cylinder 900 inside, and the outer wall of the rotating cylinder 900 has several connecting ropes 1000.

[0032] In one specific embodiment, the connecting rope 1000 allows for rapid striking of the mud during use, causing the mud to break up quickly for easier intake, reducing clogging and improving stability.

[0033] Please see Figure 2-3 The other end of the storage box 120 is sealed and connected to an external pipe 1100, and one end of the external pipe 1100 is sealed and connected to an external connector 1200. Each of the two fixing brackets 210 is equipped with several lights 1300 and cameras 1400. A battery is installed inside the connecting plate 110. A controller is installed at the top corner of the storage box 120.

[0034] In one specific embodiment, the external connector 1200 allows users to easily connect it to an external pipe and then to an external suction device. This facilitates the suction device's ability to extract sludge from the storage tank 120 via the external pipe, connector 1200, and external pipe 1100 when sludge enters the tank. This ensures continuous sludge collection within the storage tank 120, increasing sustainability and dredging efficiency. During dredging, the controller activates the camera 1400 and lighting 1300. The lighting 1300 illuminates the underground culvert and net, while the camera 1400 captures images of the sludge within the culvert and net. The controller then transmits this information to the user's terminal, allowing the user to observe the condition of the sludge within the culvert and net.

[0035] Please see Figure 1-4The tracked conveyor 100, the first electric telescopic rod 220, the torque motor 250, the servo motor 340, the second electric telescopic rod 390, the electric valve 440, the mud pump 510, and the asynchronous motor 600 are all electrically connected to the controller, which is electrically connected to the battery.

[0036] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0037] In operation, the first electric telescopic mast 220 is activated. When encountering areas with heavy water, the controller opens the first electric telescopic mast 220, causing the electric connecting bar 230 and its bottom components to move downwards. Simultaneously, the controller inflates the airbag 240 via the ventilation assembly 400, allowing the equipment to float on the water. The controller then activates the torque motor 250, which drives the propeller 260 to power the equipment, enabling it to move and dredge on the water surface. This, combined with the tracked conveyor 100, achieves amphibious capability. Next, the contact pipe 370 allows the controller to open the second electric telescopic mast 390 during operation. The support frame 380 is moved downwards to achieve height adjustment. The downward movement of the support frame 380 then moves the contact pipe 370 downwards to contact the mud. As the contact pipe 370 moves downwards, the telescopic hose 360 ​​will follow and unfold. At this time, the controller draws the mud through the contact pipe 370 via the auxiliary component 500 and sends it to the connector 320 through the telescopic hose 360. The controller then turns on the servo motor 340, which drives the auger 350 to rotate. The auger 350 sends the mud through the connecting pipe 310 to the storage tank 120 for storage. The remaining mud will be sucked in and diverted by the auxiliary component 500 and finally sent to the storage tank 120. This allows the mud to be diverted and moved, and works with the auger 350 to prevent clogging, thereby achieving the purpose of dredging, clogging prevention, and height adjustment.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
