Description

Technical Field

[0001] This application relates to the field of pipeline cleaning, and in particular to a dredging device. Background Technology

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning systems for industrial and civil buildings. They are primarily used in industrial and building engineering, with applications including: cleanroom purification systems in the electronics industry; sterile workshop purification systems in pharmaceutical and food processing plants; central air conditioning systems in hotels, shopping malls, hospitals, factories, and office buildings; exhaust ducts for dust removal, smoke extraction, and oil absorption in industrial pollution control; supply air ducts for industrial environments or workplace comfort; gas extraction systems in coal mines; and supply and return air systems for environmental control in coal mines. In industrial ventilation and dust removal, the exhaust air contains a large amount of dust, which accumulates inside the ducts over time, affecting normal ventilation.

[0003] In related technologies, pipeline robots are used to clean the inner walls of pipelines. Conventional pipeline robots can clean the inside of horizontal pipelines, but since ventilation ducts are basically metal pipes and arranged vertically, conventional pipeline cleaning devices cannot enter vertical ventilation ducts for cleaning. Summary of the Invention

[0004] This application provides a dredging device for cleaning the inside of vertical metal pipes.

[0005] The dredging device provided in this application adopts the following technical solution:

[0006] A dredging device includes a first mounting base and a second mounting base, which are spherically connected. Each mounting base has a support seat, and a circular magnetic wheel is installed inside the support seat. A cleaning brush is rotatably mounted on the first mounting base. A first driving component for driving the support seat to move is provided on the first mounting base, and a second driving component for driving the circular magnetic wheel to rotate is provided on the support seat. A dust collection component is provided on the first mounting base.

[0007] By adopting the above technical solution, when processing the pipeline, the first driving component drives the support to move, and the movement of the support causes the circular magnetic wheel to contact and adhere to the inner wall of the metal pipeline. The second driving component drives the circular magnetic wheel to rotate, causing the device to move inside the pipeline. The cleaning brush cleans the dust on the inner wall of the pipeline, and the collection component collects the dust that falls off the cleaning brush. At the bend of the pipeline, the first mounting base and the second mounting base can be bent at the connection point through a spherical connection, thus smoothly passing through the bend of the pipeline.

[0008] Preferably, the first driving assembly includes a driving screw, and both the first mounting base and the second mounting base are provided with driving screws. The first mounting base and the second mounting base are rotatably connected to the driving screws. A movable sleeve is provided on the support base. The movable sleeve passes through the first mounting base and the second mounting base and is sleeved on the driving screw. The driving screw and the movable sleeve are threaded together. A third driving assembly for driving the driving screw to rotate is provided in the first mounting base.

[0009] By adopting the above technical solution, the third drive component causes the drive screw to rotate, the drive screw to rotate causes the movable sleeve to move, the movable sleeve to move causes the support to move, and the support to move causes the circular magnetic wheel to move and fit against the inner wall of the pipe. At this time, the circular magnetic wheel is attracted to the pipe.

[0010] Preferably, the third drive assembly includes a first drive rod and a second drive rod. The first drive rod passes through the second mounting base, and the second drive rod is rotatably mounted in the second mounting base. A universal joint is provided between the first drive rod and the second drive rod, and both the first drive rod and the second drive rod are connected to the universal joint. A first bevel gear is fixedly sleeved on the first drive rod, and a second bevel gear is fixedly sleeved on the second drive rod. A third bevel gear is fixedly sleeved on the drive screw. The first bevel gear meshes with the third bevel gear located in the first mounting base, and the second bevel gear meshes with the third bevel gear located in the second mounting base. A first motor is fixedly connected in the second mounting base, and the first motor is fixedly connected to the second drive rod.

[0011] By adopting the above technical solution, the operator starts the first motor, which drives the second drive rod to rotate. The rotation of the second drive rod causes the universal joint to rotate, which in turn causes the first drive rod to rotate. The rotation of the first drive rod causes the first bevel gear to rotate, which in turn causes the second bevel gear to rotate. The rotation of the first bevel gear causes the third bevel gear in the first mounting base to rotate, which in turn causes the third bevel gear in the second mounting base to rotate. The rotation of the third bevel gear causes the drive screw to rotate, which in turn causes the movable sleeve to move. The movement of the movable sleeve causes the support base to move, and after the support base moves, the circular magnetic wheel adheres to the inner wall of the pipe.

[0012] Preferably, a connecting rod is slidably inserted inside the movable sleeve, and a first sliding groove is formed inside the movable sleeve for sliding cooperation with the connecting rod. The end of the connecting rod away from the movable sleeve is fixedly connected to the support base, and a first buffer spring is fixedly connected to the connecting rod. The end of the first buffer spring away from the connecting rod is fixedly connected to the inner end wall of the first sliding groove.

[0013] By adopting the above technical solution, when the device passes through a bend in the pipe or a protrusion on the inner wall of the pipe, the first buffer spring pushes the connecting rod to keep the circular magnetic wheel on the support base in close contact with the inner wall of the pipe at all times, preventing slippage.

[0014] Preferably, the first drive rod and the second drive rod respectively pass through both ends of the universal joint. Each of the first drive rod and the second drive rod is provided with a limit block. The universal joint has a limiting groove for sliding cooperation with the limit block. Both the first drive rod and the second drive rod are slidably connected to the universal joint. A second buffer spring and a third buffer spring are respectively provided at both ends of the universal joint. The end of the second buffer spring away from the universal joint is fixedly connected to the first drive rod, and the end of the third buffer spring away from the universal joint is fixedly connected to the second drive rod.

[0015] By adopting the above technical solution, when the first mounting base and the second mounting base bend at the connection point, the first drive rod and the second drive rod respectively compress the second buffer spring and the third buffer spring, thereby ensuring that the first drive rod and the second drive rod are always connected to the universal joint, preventing the first drive rod or the second drive rod from bending due to the rigid connection with the universal joint.

[0016] Preferably, the second drive assembly includes a rubber wheel, a rotating column is inserted into the support base, the rotating column is rotatably connected to the support base, the rubber wheel is fixedly sleeved on the rotating column, the rubber wheel abuts against the circular magnetic wheel, and a second motor is provided on the support base, the output end of the second motor is fixedly connected to the rotating column.

[0017] By adopting the above technical solution, when the circular magnetic wheel is adsorbed on the inner wall of the pipe and the device needs to move on the inner wall of the pipe, the second motor is started. The second motor drives the rubber wheel to rotate, and the rotation of the rubber wheel causes the circular magnetic wheel to rotate, thereby moving the device inside the pipe.

[0018] Preferably, the collection component includes a negative pressure fan, the first mounting base has a channel for dust to pass through, the negative pressure fan is rotatably mounted in the channel, the first mounting base is provided with a collection box for storing dust, and the first mounting base is provided with a fourth drive component for driving the negative pressure fan and the cleaning brush to rotate.

[0019] By adopting the above technical solution, when the circular magnetic wheel rotates and the device moves inside the pipe, the fourth drive component drives the negative pressure fan and the cleaning brush to rotate. The cleaning brush cleans the dust on the inner wall of the pipe, and after the negative pressure fan rotates, it sucks the dust cleaned by the cleaning brush into the collection box.

[0020] Preferably, the fourth drive component includes a third motor and a reducer. The third motor is disposed in the first mounting base. A first spur gear is fixedly sleeved on the output end of the third motor. A second spur gear is fixedly sleeved on the negative pressure fan. The first spur gear and the second spur gear mesh with each other. The reducer is connected to the output end of the third motor and the negative pressure fan respectively.

[0021] By adopting the above technical solution, the third motor starts, drives the first spur gear to rotate, the rotation of the first spur gear causes the second spur gear to rotate, the rotation of the second spur gear causes the negative pressure fan to rotate, and at the same time the third motor drives the cleaning brush to rotate through the reducer. The rotation of the cleaning brush cleans the dust on the inner wall of the pipe, and the rotation of the negative pressure fan collects the cleaned dust.

[0022] Preferably, the first mounting base is provided with a collection cover near the end of the cleaning brush.

[0023] By adopting the above technical solutions, the collection hood can limit the dust dispersion range and increase the collection radius of the negative pressure fan.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting a first driving component and a circular magnetic wheel, after the first driving component drives the support base to move so that the circular magnetic wheel is attracted to the inner wall of the metal, the second driving component drives the circular magnetic wheel to rotate so that the device can move inside the vertical metal pipe;

[0026] 2. By setting a first return spring, when the device passes through a bend in the pipe or a protrusion in part of the inner wall of the pipe, the first buffer spring pushes the connecting rod so that the circular magnetic wheel on the support base is always in close contact with the inner wall of the pipe, preventing slippage;

[0027] 3. By setting up a negative pressure fan and a cleaning brush, after the cleaning brush sweeps the dust off the inner wall of the pipe, the negative pressure fan collects the swept dust into the collection box. Attached Figure Description

[0049] The implementation principle of a dredging device according to an embodiment of this application is as follows: The operator starts the first motor 36, which drives the second drive rod 34 to rotate. The rotation of the second drive rod 34 causes the universal joint 35 to rotate, which in turn causes the first drive rod 33 to rotate. The rotation of the first drive rod 33 causes the first bevel gear 331 to rotate, which in turn causes the second bevel gear 341 to rotate. The rotation of the first bevel gear 331 causes the third bevel gear 342 in the first mounting base 1 to rotate, which in turn causes the third bevel gear 342 in the second mounting base 2 to rotate. The rotation of the third bevel gear 342 causes the drive screw 31 to rotate, which in turn causes the movable sleeve 32 to move. The movement of the movable sleeve 32 causes the support base 11 to move. After the support base 11 moves, the circular magnetic wheel 12 is attracted to the inner wall of the pipe.

[0050] When the circular magnetic wheel 12 is adsorbed onto the inner wall of the pipe and the device needs to move within the pipe, the second motor 43 is started. The second motor 43 drives the rubber wheel 41 to rotate, which causes the circular magnetic wheel 12 to rotate, thus moving the device within the pipe.

[0051] The third motor 46 starts, driving the first spur gear 461 to rotate. The rotation of the first spur gear 461 causes the second spur gear 462 to rotate, which in turn causes the negative pressure fan 14 to rotate. Simultaneously, the third motor 46 drives the cleaning brush 13 to rotate via the reducer 47. The cleaning brush 13 cleans the dust on the inner wall of the pipe, and the negative pressure fan 14 collects the cleaned dust. By setting the first drive assembly 3 and the circular magnetic wheel 12, after the first drive assembly 3 drives the support base 11 to move so that the circular magnetic wheel 12 adheres to the inner wall of the metal, the second drive assembly 4 drives the circular magnetic wheel 12 to rotate, enabling the device to move inside the vertical metal pipe. At the same time, the cleaning brush 13 and the negative pressure fan 14 clean the dust accumulated on the inner wall of the pipe.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
