Description

Technical Field

[0001] This invention relates to the field of water conservancy construction technology, and in particular to a device for dredging water channels used in water conservancy and hydropower construction. Background Technology

[0002] In water conservancy and hydropower construction, dredging of water channels is an important part of ensuring smooth water flow and improving the efficiency of water conservancy facilities. Water channel dredging devices are used to remove sediment, weeds and other obstacles in the channels to maintain the designed flow and water quality of the channels. Usually, water channel dredging robots are used to carry out automated dredging operations on the bottom of the channels. The water channel dredging robots use mechanized means to clean the silt at the bottom of the channels to ensure smooth water flow.

[0003] Existing dredging devices for water conservancy and hydropower construction require placing a dredging robot inside the canal. Operators remotely control the robot, bringing its suction bucket close to the silt at the bottom of the canal. The dredging process relies on the cooperation of a water pump and the suction bucket, utilizing negative pressure to effectively remove the silt from the bottom of the canal. However, during the dredging process, the silt becomes viscous due to prolonged deposition, increasing the difficulty of the cleaning work. This viscous silt causes significant resistance to the dredging robot's movement and suction, thus affecting the dredging effect. This solution proposes a new dredging device for water conservancy and hydropower construction to address these problems. Summary of the Invention

The working principle of the vehicle body 1 and the suction bucket 2 is the same as that of the intelligent underwater dredging robot of model 842. Multiple fixed frames 12 are fixedly connected to the top of the suction bucket 2, and the fixed frames 12 support the drive unit and the mounting unit. The drive unit and the mounting unit are supported and fixed by multiple conveyor frames 7. The end of the conveyor frame 7 away from the mounting unit is interlocked with multiple nozzles 8. The vehicle body 1 is placed in the water channel, and the movement of the vehicle body 1 drives the suction bucket 2 to move. The top of the sludge suction bucket 2 is equipped with a sludge suction pipe, which is connected to an external water pump. The movement of the sludge suction bucket 2 drives the fixed frame 12 to move, thereby moving the conveying frame 7 and the nozzle 8 to the front end of the sludge. The conveying frame 7 and the nozzle 8 spray high-pressure cleaning water onto the surface of the sludge, thereby diluting and flushing the sludge and dispersing the sludge at the bottom of the channel, so as to facilitate the subsequent sludge suction operation in cooperation with the sludge suction bucket 2 and the sludge suction pipe. At the same time, the angle of the conveying frame 7 and the nozzle 8 can be adjusted by the drive unit and the installation unit to increase the flushing range. Specifically, the drive unit includes: Rotating rod 14 is disposed between multiple fixed frames 12. Both ends of rotating rod 14 are rotatably inserted and connected to the ends of multiple fixed frames 12 away from the suction bucket 2.

It should be noted that the rotating rod 14 is positioned between multiple fixed frames 12, with both ends of the rotating rod 14 rotatably interlocked with the ends of the multiple fixed frames 12 furthest from the suction hopper 2. One side of one mounting frame 15 is fixedly connected to the drive motor 13, and the output end of the drive motor 13 is fixedly connected to one end of the rotating rod 14. When the vehicle body 1 is placed in the water channel, the movement of the vehicle body 1 drives the movement of the suction hopper 2. The top of the suction hopper 2 is equipped with a suction pipe, which is connected to an external water pump. The movement of the suction hopper 2 drives the fixed frames. 12. Move the conveyor frame 7 and nozzle 8 to the front of the sludge. High-pressure cleaning water is sprayed onto the surface of the sludge through the conveyor frame 7 and nozzle 8 to dilute and flush the sludge, so that the suction bucket 2 can perform suction operation. At the same time, the drive motor 13 can be started, which drives the rotating rod 14 to rotate. The rotating rod 14 drives the mounting part to rotate, which drives the conveyor frame 7 and nozzle 8 to rotate. The nozzle 8 can be adjusted according to the height of the sludge at the bottom of the canal to increase the flushing range and improve the sludge removal effect. Specifically, the installation department includes: Mounting bracket 15, one end of multiple mounting brackets 15 is sleeved with the outer wall of rotating rod 14; Connecting frame 16, one end of multiple connecting frames 16 is respectively hinged to the end of multiple mounting frames 15 away from the rotating rod 14, and the end of multiple connecting frames 16 away from the mounting frame 15 is respectively fixedly connected to the end of multiple conveying frames 7 away from the nozzle 8; It should be noted that the outer wall of the rotating rod 14 is sleeved with multiple mounting brackets 15. The ends of the multiple mounting brackets 15 away from the rotating rod 14 are respectively hinged to multiple connecting brackets 16. The ends of the multiple connecting brackets 16 away from the rotating rod 14 are respectively fixedly connected to the ends of multiple conveying frames 7 away from the nozzles 8. The vehicle body 1 is placed in the water channel. The movement of the vehicle body 1 drives the sludge suction bucket 2 to move. The top of the sludge suction bucket 2 is equipped with a sludge suction pipe, which is connected to an external water pump. The movement of the sludge suction bucket 2 drives the fixed bracket 12 to move, thereby moving the conveying frame 7 and the nozzles 8 to the front end of the sludge. The conveyor frame 7 and nozzles 8 spray high-pressure cleaning water onto the surface of the silt, thereby diluting and flushing the silt to facilitate subsequent silt suction by the suction bucket 2. At the same time, the drive motor 13 can be started, which drives the rotating rod 14 to rotate. The rotating rod 14 drives multiple mounting frames 15 to rotate synchronously. The mounting frames 15 drive multiple connecting frames 16 to rotate synchronously. The rotation of the connecting frames 16 drives multiple conveyor frames 7 and nozzles 8 to rotate up and down simultaneously, thereby allowing the nozzles 8 to be adjusted according to the height of the silt at the bottom of the canal, increasing the flushing range and improving the silt removal effect. Rotating rod 14 has rotating frames 20 sleeved on both ends of its outer wall. Rotating plates 21 are fixedly installed on the top of the ends of the rotating frames 20 away from the rotating rod 14. The ends of the rotating plates 21 away from the rotating frames 20 are slidably inserted into the adjustment part. It should be noted that one end of each of the multiple rotating frames 20 is sleeved with the outer walls of both ends of the rotating rod 14, and the ends of the multiple rotating frames 20 away from the rotating rod 14 are fixedly connected to multiple rotating plates 21. During the dredging process, the rotating rod 14 is driven to rotate by the drive motor 13, which in turn drives the rotating frames 20 to rotate, and the rotating frames 20 to rotate the rotating plates 21. Through the cooperation of the rotating frames 20 and the rotating plates 21, the adjusting part rotates synchronously with the rotating rod 14, preventing the conveying frame 7 from separating from the adjusting part and the transmission part when it rotates. At the same time, the adjusting part is installed and fixed by the rotating frames 20 and the rotating plates 21. Specifically, the regulating section includes: An adjusting rod 11 is disposed between multiple rotating plates 21. Both ends of the adjusting rod 11 are slidably inserted and connected to the ends of the multiple rotating plates 21 that are close to each other. The outer wall of the adjusting rod 11 is sleeved with multiple transmission parts. Mounting plate 22, one end of which is fixedly connected to one side of one of the rotating plates 21; Hydraulic press 23 is fixedly installed on the top of mounting plate 22, and the output end of hydraulic press 23 is fixedly connected to one end of adjusting rod 11. It should be noted that the adjusting rod 11 is positioned between multiple rotating plates 21, with both ends of the adjusting rod 11 slidably interlocked with the adjacent ends of the multiple rotating plates 21. One side of one rotating plate 21 is fixedly connected to the mounting plate 22, and the top of the mounting plate 22 is fixedly connected to the hydraulic press 23. The output end of the hydraulic press 23 is fixedly connected to one end of the adjusting rod 11. When the vehicle body 1 is placed in the water channel, the movement of the vehicle body 1 drives the sludge suction bucket 2 to move. The top of the sludge suction bucket 2 is equipped with a sludge suction pipe, which is connected to an external water pump. The movement of the sludge suction bucket 2 drives the fixed frame 12 to move, thereby causing the conveying frame 7 and... The nozzle 8 moves to the front end of the sludge and sprays high-pressure cleaning water onto the surface of the sludge through the conveyor frame 7 and the nozzle 8, thereby diluting and rinsing the sludge to facilitate the subsequent sludge suction operation of the suction bucket 2. The hydraulic press 23 can be started, and the output end of the hydraulic press 23 pushes the adjusting rod 11 to move, so that the adjusting rod 11 slides between multiple rotating plates 21. The movement of the adjusting rod 11 drives the transmission part to move, and the transmission effect of the transmission part causes the conveyor frame 7 and the nozzle 8 to move left and right with the adjusting rod, so that the nozzle 8 can be adjusted at the angle according to the size of the bottom of the water channel, thereby increasing the rinsing range of the nozzle 8 and preventing sludge from remaining on both sides of the water channel. Specifically, the transmission unit includes: Transmission frame 19, one end of multiple transmission frames 19 is sleeved with the outer wall of adjusting rod 11; One end of the multiple transmission rods 18 is respectively hinged to the end of the multiple transmission frames 19 away from the adjusting rod 11; The movable frame 17 has one end hinged to the end of the multiple transmission rods 18 away from the transmission frame 19, and the ends of the multiple movable frames 17 away from the transmission rods 18 are fixedly connected to the top of the multiple conveyor frames 7.

[0025] It should be noted that the outer wall of the adjusting rod 11 is sleeved with multiple transmission frames 19, the ends of the multiple transmission frames 19 away from the transmission rod 18 are hinged to the multiple transmission rods 18, the ends of the multiple transmission rods 18 away from the transmission frame 19 are hinged to multiple movable frames 17, and the ends of the multiple movable frames 17 away from the transmission rod 18 are fixedly connected to the top of multiple conveying frames 7. Rotational damping is provided at the connection points of the transmission frames 19, transmission rods 18, and movable frames 17. Rotational damping is used to control the rotation of the transmission frames 19, transmission rods 18, and movable frames 17. The inertia of the rotating rod 18 and the moving frame 17 is reduced, allowing the vehicle body 1 to be placed in the water channel. The movement of the vehicle body 1 moves the suction bucket 2. The suction bucket 2 has a suction pipe at its top, connected to an external water pump. The movement of the suction bucket 2 moves the fixed frame 12, which in turn moves the conveying frame 7 and the nozzle 8 to the front of the sludge. High-pressure cleaning water is sprayed onto the sludge surface through the conveying frame 7 and the nozzle 8, diluting and flushing the sludge to facilitate subsequent suction operations by the suction bucket 2. Start the drive motor 13, which drives the rotating rod 14 to rotate. The rotating rod 14 drives the mounting frame 15 to rotate. The mounting frame 15 drives the connecting frame 16 to rotate. The connecting frame 16 drives the conveying frame 7 and the nozzle 8 to rotate up and down, thereby adjusting the nozzle 8 according to the height of the silt at the bottom of the water channel. At the same time, the hydraulic press 23 can be started. The output end of the hydraulic press 23 pushes the adjusting rod 11 to move, so that the adjusting rod 11 slides between multiple rotating plates 21. The movement of the adjusting rod 11 drives the transmission frame 19 to move. The movement of the transmission frame 19 drives the transmission rod 18 to rotate. The rotation of the transmission rod 18 pulls the moving frame 17 to move. The movement of the moving frame 17 drives the conveying frame 7 to swing. The swing of the conveying frame 7 causes the nozzle 8 to swing left and right, thereby adjusting the angle of the nozzle 8 according to the size of the bottom of the water channel, increasing the flushing range of the nozzle 8, preventing silt from remaining on both sides of the water channel, and diluting and flushing the silt with the nozzle 8, thereby reducing the viscosity of the silt and improving the suction efficiency. Furthermore, a limit block 10 is fixedly installed at the end of the adjusting rod 11 away from the hydraulic press 23, and protective blocks 9 are fixedly installed on both sides of the multiple conveyor frames 7 near the nozzle 8. It should be noted that multiple protective blocks 9 are fixedly connected to the two sides of multiple conveyor frames 7 near the nozzle 8. The multiple protective blocks 9 are made of elastic rubber. The protective blocks 9 protect the two sides of the conveyor frame 7 to prevent the conveyor frame 7 from colliding and being damaged due to inertia when it swings left and right, thereby improving stability. The limiting block 10 is fixedly connected to the end of the adjusting rod 11 away from the hydraulic press 23. The limiting block 10 restricts the movement of the adjusting rod 11 to prevent the adjusting rod 11 from moving too much and separating from the rotating plate 21, thereby improving stability. The top of the sludge suction hopper 2 is provided with a conveying section and a diversion section. The diversion section is fixedly connected to the top of the sludge suction hopper 2, and the conveying section and the diversion section are interlocked. Specifically, the diversion section includes: Support frame 3, multiple support frames 3 are fixedly installed on the top of suction hopper 2; Diversion pipe frame 4, the bottom of both ends of the diversion pipe frame 4 are fixedly connected to the ends of multiple support frames 3 away from the suction bucket 2, and the side of the diversion pipe frame 4 near the conveying frame 7 is interwoven with the conveying part.

It should be noted that multiple support frames 3 are located behind multiple fixed frames 12. One end of each support frame 3 is fixedly connected to the top of the suction hopper 2, and the ends of each support frame 3 away from the suction hopper 2 are respectively fixedly connected to the bottom of both ends of the diversion pipe frame 4. The top of the diversion pipe frame 4 is inserted and connected to one end of the first water supply pipe 5, and the end of the diversion pipe frame 4 near the conveying frame 7 is inserted and connected to multiple second water supply pipes 6. The first water supply pipe 5, the diversion pipe frame 4, the second water supply pipes 6, the conveying frame 7, and the nozzle 8 are internally connected. The first water supply pipe 5 is located away from the diversion pipe. One end of the frame 4 is connected to an external water pump, which delivers clean water to the first water supply pipe 5. The first water supply pipe 5 then delivers the clean water to the diversion pipe frame 4, which then distributes the clean water evenly to multiple second water supply pipes 6. The multiple second water supply pipes 6 then deliver the clean water to multiple conveying frames 7. The conveying frames 7 and the nozzles 8 work together to pressurize the clean water and spray it onto the surface of the sludge. The clean water dilutes and washes away the sludge, thereby reducing its viscosity and improving the suction efficiency.
