Description

Technical Field

[0001] The present invention relates to the technical field of dredging, and in particular to a portable vehicle-mounted underwater dredging robot. Background Art

[0002] Many urban river spaces are constantly being occupied and squeezed. Cement slabs are artificially laid on the river, and then roadbeds or house foundations are covered on the cement slabs to build bridges, roads, and buildings. The original river channels are transformed into culverts. With a large amount of sewage being directly discharged into the culverts, anaerobic odor, silt deposition and other problems occur in the dark and confined river space. If these "black and smelly" channels are not rectified, it will seriously affect the urban environment and damage the city's image.

[0003] However, existing underwater dredging robots generally move using tracks. Although this can effectively prevent slipping, they are slow in movement, which seriously affects the dredging efficiency. In addition, the existing dredging process often uses suction operations, but large pieces of garbage are often present when the dredging is being pumped out, which can easily cause blockage of the dredging system, forcing staff to frequently go down the well to remove the blocked garbage, further affecting the robot's operating efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a portable vehicle-mounted underwater dredging robot.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A portable vehicle-mounted underwater dredging robot, comprising:

[0007] case;

[0008] A bearing plate is rotatably mounted on the top of the shell, and a dredging bucket is fixedly mounted on the side of the bearing plate through two bent rods;

[0009] A silt extraction pipeline is fixedly connected to the top of the silt removal bucket, and the top of the silt extraction pipeline is closed. A suction pump is fixedly installed on the top of the bearing plate. The suction port of the suction pump is connected to the silt extraction pipeline through the suction pipe, and the discharge port of the suction pump is fixedly connected to the silt discharge pipe;

[0017] Preferably, the adjustment assembly comprises a groove opened on the top of the shell, a hydraulic rod is rotatably mounted in the groove, and a driving end of the hydraulic rod is hinged to the bottom of the bearing plate.

[0024] Compared with the existing technology, the advantages of the portable vehicle-mounted underwater dredging robot provided by the present invention are:

[0029] To sum up, the present invention not only improves the moving speed of the device, but also facilitates the multi-directional movement of the device through two independently operable spiral walking pieces. At the same time, during dredging, two reverse spiral auger pieces rotating in the same direction can be used to push the silt into the middle of the silt removal bucket so that the suction pump can draw it into the silt extraction pipeline. Moreover, under each high-speed rotating crushing knife, the silt can be prevented from clogging the silt extraction pipeline, thereby improving the dredging efficiency of the device.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1 to 4 , a portable vehicle-mounted underwater dredging robot, comprising:

[0037] The shell 1 has four lifting rings 29 symmetrically fixed on the top of the shell 1, which facilitates the use of an external crane to lift it. A cable 6 is fixedly passed through the outer side of the shell 1. A controller is also installed inside the shell 1 and is electrically connected to the cable 6, and the other end of the cable 6 is connected to an external remote control.

[0038] The supporting plate 2 is rotatably mounted on the top of the shell 1, and a silt removal bucket 4 is fixedly mounted on the side of the supporting plate 2 through two bent rods 3. A silt extraction pipe 5 is fixedly connected to the top of the silt removal bucket 4, and the top of the silt extraction pipe 5 is closed. A suction pump 7 is fixedly mounted on the top of the supporting plate 2, and the suction port of the suction pump 7 is connected to the silt extraction pipe 5 through a suction pipe 8, and the discharge port of the suction pump 7 is fixedly connected to a silt extraction pipe 9. When silting, the suction pump 7 is started to pump the silt in the silt removal bucket 4 into the silt extraction pipe 9 through the suction pipe 8 and the silt extraction pipe 5 and discharge it, and the silt extraction pipe 9 can also be connected to an external pipe to discharge the silt to a designated location.

[0039] The dredging component is used to squeeze the silt into the dredging bucket 4. The dredging component includes a worm 10 rotatably installed in the dredging bucket 4. A driving motor 11 for driving the worm 10 to rotate is fixedly installed on the outer side of the dredging bucket 4. A worm wheel 12 is meshed above the worm 10. A rotating shaft 13 is coaxially fixedly installed on the surface of the worm wheel 12, and the rotating shaft 13 is rotatably installed in the dredging bucket 4. Two spiral auger pieces 14 are symmetrically fixedly installed on the surface of the rotating shaft 13, and the spiral directions of the two spiral auger pieces 14 are set in opposite directions. The driving motor 11 is started to drive the worm 10 to rotate, and the rotating shaft 13 is driven to rotate by the worm wheel 12 meshing therewith, so that the two spiral auger pieces 14 rotate synchronously in the same direction. Finally, the silt is pushed toward the middle of the dredging bucket 4.

[0040] Two walking components are used to control the movement of the shell 1. The walking components include two electric telescopic frames 15 symmetrically fixedly installed on the bottom of the shell 1. A roller 16 is installed between the driving ends of the two electric telescopic frames 15 for common rotation. A motor 17 for driving the roller 16 to rotate is fixedly installed on the surface of the driving end of one of the electric telescopic frames 15. The height of the shell 1 can also be adjusted by telescoping the driving end of each electric telescopic frame 15, so that the device can move more freely in the silt, thereby improving the adaptability of the device.

[0041] A spiral walking piece 18 is fixedly installed on the surface of the roller 16, and the spiral directions of the surfaces of the two spiral walking pieces 18 are set in opposite directions. By driving the two spiral walking pieces 18 to move synchronously in opposite directions by two motors 17 respectively, the forward and backward movement of the shell 1 can be controlled, and by driving the two spiral walking pieces 18 to move synchronously in the same direction respectively, the lateral movement of the shell 1 can be controlled. At the same time, by controlling the two spiral walking pieces 18 to rotate independently by two motors 17, that is, one rotates and the other does not rotate, the shell 1 can be controlled to perform a turning operation.

[0042] The adjusting component is used to adjust the angle of the supporting plate 2. The adjusting component includes a groove 21 opened on the top of the shell 1. A hydraulic rod 22 is rotatably installed in the groove 21, and the driving end of the hydraulic rod 22 is hinged to the bottom of the supporting plate 2. By controlling the extension of the driving end of the hydraulic rod 22, the supporting plate 2 can be driven to rotate to adjust its angle, so that the position of the dredging bucket 4 can be adjusted according to actual conditions to better dredge the sludge.

[0043] The crushing assembly is used to break up the silt in the silt extraction pipeline 5. The crushing assembly includes a first bevel gear 23 coaxially fixedly mounted on the surface of the worm 10. A second bevel gear 24 is meshed above the first bevel gear 23. The diameter of the first bevel gear 23 is greater than the diameter of the second bevel gear 24. When the worm 10 rotates, the first bevel gear 23 can drive the second bevel gear 24 with a smaller diameter that is meshed with it to rotate at high speed.

[0044] A crushing shaft 25 is coaxially fixedly installed on the top of the second bevel gear 24, and the crushing shaft 25 is rotatably installed on the inner top of the silt extraction pipe 5. A plurality of crushing knives 26 are fixedly installed on the surface of the crushing shaft 25. A bearing 27 is fixedly installed on the surface of the crushing shaft 25. The outer ring of the bearing 27 is fixedly installed in the silt removal bucket 4 through a fixing rod 28, thereby ensuring the stability of the crushing shaft 25 during rotation.

[0045] Furthermore, a high-definition camera 19 is fixedly installed on the surface of the sludge extraction pipeline 5, and two lighting lamps 20 are symmetrically fixedly installed on the surface of the shell 1.

[0046] The working principle of the present invention is:

[0047] When in use, the device is first moved to the location where silt is required to be desilted by crane or manually, and then the two motors 17, the drive motor 11 and the suction pump 7 are controlled by an external remote controller;

[0048] When controlling movement, the two motors 17 drive the two spiral walking pieces 18 to move synchronously in opposite directions respectively, so as to control the forward and backward movement of the housing 1, and the two spiral walking pieces 18 are driven to move synchronously in the same direction respectively, so as to control the lateral movement of the housing 1. At the same time, the two motors 17 control the two spiral walking pieces 18 to rotate independently, that is, one rotates and the other does not rotate, so as to control the housing 1 to perform a turning operation;

[0049] When desilting, the driving motor 11 is started to drive the worm 10 to rotate, and the worm wheel 12 meshing therewith drives the rotating shaft 13 to rotate, so that the two spiral auger pieces 14 rotate synchronously in the same direction, and when the desilting bucket 4 contacts the silt, the silt can be pushed to the middle of the desilting bucket 4;

[0050] Then, the suction pump 7 can pump the sludge in the silt removal bucket 4 into the sludge discharge pipe 9 through the suction pipe 8 and the sludge extraction pipe 5 and discharge it, and the sludge discharge pipe 9 can also be connected to an external pipe to discharge the sludge to a designated location;

[0051] At the same time, when the silt enters the silt extraction pipeline 5, the worm 10 will also drive the second bevel gear 24 with a small diameter that is meshed with it to rotate at high speed through the first bevel gear 23, so that each crushing knife 26 crushes the silt to prevent the silt from clogging the silt extraction pipeline 5 and affecting the silt removal work.

[0052] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
