Description

Technical Field

[0001] This invention relates to the technical field of underwater cable pipeline dredging, and in particular to an underwater cable pipeline dredging robot. Background Technology

[0002] Underwater cable conduits are structures specifically designed for the laying and protection of underwater cables. After prolonged use, the interior of underwater cable conduits is easily clogged by impurities, plant roots, aquatic shellfish, and algae, making it inconvenient for workers to pass new cables through them. Therefore, when laying new cables, it is necessary to use a municipal pipeline dredging device disclosed in utility model patent CN220184241U and a high-pressure pipeline dredging device and high-pressure pump disclosed in invention patent CN116623783A to spray high-pressure water into the underwater cable conduit for internal transport.

[0003] However, during use, it was found that the existing dredging equipment has a relatively simple mechanism, making it difficult to eradicate plant roots, aquatic shellfish, and aquatic algae in underwater cable pipelines. It is also inconvenient to clean impurities under the cables in underwater cable pipelines, resulting in poor practicality. Therefore, there is an urgent need for an underwater cable pipeline dredging robot to improve the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an underwater cable pipeline dredging robot that places a support mechanism in an underwater cable pipeline, drives the support mechanism to move in the underwater cable pipeline through a moving mechanism, dredges the interior of the underwater cable pipeline through a dredging mechanism, and cleans plant roots, aquatic shellfish and aquatic algae in the underwater cable pipeline through a sealing mechanism in conjunction with the dredging mechanism.

[0005] The present invention discloses an underwater cable pipeline dredging robot, which includes a support mechanism; it also includes a moving mechanism, a sealing mechanism, and a dredging mechanism, all of which are mounted on the support mechanism.

[0006] The moving mechanism adjusts the position of the supporting mechanism, the sealing mechanism seals a section of the underwater cable conduit, and the unblocking mechanism unblocks the interior of the underwater cable conduit.

[0007] The support mechanism is placed in the underwater cable duct, and the moving mechanism drives the support mechanism to move in the underwater cable duct. At the same time, the unblocking mechanism unblocks the inside of the underwater cable duct, and the sealing mechanism works in conjunction with the unblocking mechanism to clean the plant roots, aquatic shellfish and aquatic algae in the underwater cable duct.

[0008] Preferably, the support mechanism includes two sets of frames, multiple sets of guide rails, multiple sets of first electric cylinders, multiple sets of first support frames, multiple sets of first telescopic rods, multiple sets of driven wheels, and a limiting mechanism. The multiple sets of guide rails are respectively mounted on the two sets of frames, and the two sets of first support frames are respectively slidably mounted on the multiple sets of guide rails. One end of each set of first electric cylinders is mounted on one set of frames, and the other end of each set of first electric cylinders is mounted on one set of first support frames. The multiple sets of first telescopic rods are respectively mounted on the two sets of frames and the multiple sets of first support frames. The multiple sets of driven wheels are respectively mounted on the multiple sets of first telescopic rods, and the limiting mechanism is mounted on the frame. The two sets of frames are then joined together to form a circle, allowing the limiting mechanism to support the cable in the underwater cable conduit. The two sets of frames are then connected by bolts. By adjusting the length of the multiple sets of first telescopic rods, the multiple sets of driven wheels are supported on the inner wall of the underwater cable conduit, facilitating adjustment of the unblocking position and improving the practicality of the equipment.

[0009] Preferably, the limiting mechanism includes two sets of springs and two sets of support shafts. One end of each set of springs is mounted on one set of frames, and the other end of each set of support shafts is mounted on the other end of each set of springs. The cable in the underwater cable pipeline is placed between the two sets of support shafts, and then the two sets of frames are connected together. The cable is limited by the two sets of support shafts. When the equipment moves in the underwater cable pipeline, the cable is supported by the two sets of support shafts, which facilitates the cleaning mechanism to remove impurities under the cable, thereby improving the practicality of the equipment.

[0010] Preferably, the moving mechanism includes two sets of winding shafts, two sets of first motors, two sets of wire ropes, a safety buckle, two sets of second support frames, two sets of second telescopic rods, multiple sets of drive wheels, multiple sets of second motors, and a braking mechanism. The two sets of winding shafts are rotatably mounted on the left and right ends of the top frame, respectively. Both sets of first motors are fixedly mounted on the top frame and provide power to the two sets of winding shafts. The two sets of wire ropes are wound onto the two sets of winding shafts. The safety buckle is mounted on one end of one set of wire ropes. Both sets of second support frames are mounted on one end of the other set of wire ropes. The two sets of second telescopic rods are mounted on the two sets of second support frames. Multiple sets of drive wheels are rotatably mounted on the two sets of second telescopic rods. Multiple sets of second motors are fixedly mounted on the two sets of second telescopic rods and provide constant force to the multiple sets of drive wheels. The braking mechanism is mounted on the two sets of second telescopic rods. The safety buckle is hung outside the underwater cable conduit. After securing the components, connect the two sets of second support frames together. By adjusting the lengths of the two sets of second telescopic rods, multiple sets of drive wheels are supported on the inner wall of the underwater cable duct. Multiple sets of second motors are activated, driving the drive wheels to move inside the underwater cable duct. Simultaneously, a set of first motors runs in reverse, causing a set of winding shafts to unwind a set of wire ropes. After moving the two sets of second support frames to the blockage location in the underwater cable duct, the braking mechanism supports the multiple sets of drive wheels. Then, one set of first motors runs forward while the other runs in reverse, causing a set of winding shafts to wind up a set of wire ropes and another set of winding shafts to unwind another set of wire ropes, moving the equipment to the blockage location. After clearing the underwater cable duct, the other set of first motors runs in reverse, causing the other set of winding shafts to wind up another set of wire ropes, moving the equipment outside the underwater cable duct, thus improving the equipment's practicality.

[0011] Preferably, the braking mechanism includes multiple sets of second electric cylinders and multiple sets of brake blocks. The multiple sets of second electric cylinders are respectively mounted on two sets of second telescopic rods, and the multiple sets of brake blocks are respectively mounted on the multiple sets of second electric cylinders. By extending the multiple sets of second electric cylinders, the multiple sets of brake blocks are supported on the inner wall of the underwater cable pipeline to brake the multiple sets of drive wheels, thereby improving the practicality of the equipment.

[0012] Preferably, the unblocking mechanism includes a heating mechanism and a flushing mechanism, both of which are mounted on the top frame. The flushing mechanism flushes impurities in the underwater cable conduit to unblock it, while the heating mechanism, in conjunction with the sealing mechanism, cleans plant roots, aquatic shellfish, and aquatic algae from the underwater cable conduit, thereby improving the equipment's practicality.

[0013] Preferably, the flushing mechanism includes a water supply pipe, a rotary joint, a spray pipe, multiple sets of first high-pressure nozzles, and multiple sets of second high-pressure nozzles. The water supply pipe is rotatably mounted on the top frame, the rotary joint is rotatably mounted on one end of the water supply pipe, and the spray pipe is mounted on the other end of the water supply pipe. Both the multiple sets of first and second high-pressure nozzles are mounted on the spray pipe. The rotary joint is connected to a pressurization device. When the device moves within the underwater cable pipeline, the pressurized water is sprayed out through the multiple sets of second high-pressure nozzles. Simultaneously, the impact force generated by the water sprayed from the multiple sets of second high-pressure nozzles causes the spray pipe to rotate, flushing the inner wall of the underwater cable pipeline with the water sprayed from the multiple sets of second high-pressure nozzles. When a blockage is encountered, the multiple sets of second high-pressure nozzles are closed, and the multiple sets of first high-pressure nozzles are opened, allowing the pressurized water to be sprayed out to clean the blockage impurities, thereby improving the practicality of the device.

[0014] Preferably, the water supply pipe, heating pipe, and propeller are mounted on the top frame, the heating pipe, and the propeller. The water supply pipe is connected to a water source. After a section of the underwater cable is sealed by a sealing mechanism, water is discharged into the underwater cable. At the same time, the heating pipe and propeller are turned on, allowing the water to circulate in the heating pipe. The water is heated to 90 degrees Celsius by the heating pipe, killing plant roots, aquatic shellfish, and aquatic algae in the underwater cable, thereby improving the practicality of the equipment.

[0015] Preferably, the sealing mechanism includes a third support frame, multiple sets of third electric cylinders, multiple sets of first connecting rods, multiple sets of second connecting rods, a sealing cloth, a first sealing airbag, and multiple sets of second sealing airbags. The third support frame is slidably mounted on the first support frame. The multiple sets of third electric cylinders are all fixedly mounted on the first support frame, and one end of each set of third electric cylinders is connected to the third support frame. One end of each set of first connecting rods is rotatably mounted on the first support frame. One end of each set of second connecting rods is rotatably mounted on the multiple sets of first connecting rods, and the other end of each set of second connecting rods is rotatably mounted on the third support frame. The sealing cloth is mounted on the multiple sets of first connecting rods. The sealing airbag is installed on the edge of the sealing cloth, and multiple sets of second sealing airbags are installed on two sets of frames respectively. The first and second sealing airbags are connected to the air pump. The positions of multiple sets of first support frames are adjusted by extending or retracting multiple sets of first electric cylinders. Then, the positions of multiple sets of first support frames are adjusted by retracting multiple sets of third electric cylinders. The third support frames cooperate with multiple sets of second connecting rods to drive the multiple sets of first connecting rods to stand up. Then, the air pump discharges air into the first and second sealing airbags, causing the first and second sealing airbags to expand and seal a section of the underwater cable pipeline, which facilitates the storage of hot water and improves the practicality of the equipment.

[0016] Preferably, the sealing cloth is equipped with an electrically controlled valve; when water is drained into the unfolded sealing mechanism, the air in the sealing mechanism is discharged through the electrically controlled valve, thereby improving the practicality of the equipment.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By sealing a section of the underwater cable conduit and then draining water into it, the plant roots, aquatic shellfish, and aquatic algae in the underwater cable conduit are killed by heating the water, thereby improving the equipment's unblocking effect.

[0019] 2. By lifting the cable during the dredging process, the equipment can easily clean up the impurities under the cable;

[0020] 3. Improve the ease of moving the equipment in underwater cable ducts by using a moving mechanism for traction. Attached Figure Description
