Description

Technical Field

[0001] This invention belongs to the field of dredging technology, specifically relating to a culvert dredging system and dredging method. Background Technology

[0002] In the course of urban development and construction, some drainage culverts have accumulated solid matter over time due to factors such as runoff carrying silt and slow water flow. In addition, human dumping of domestic and construction waste has gradually hindered the normal use of the pipes, causing internal blockages and making them prone to problems such as sewage overflow during rainy days and urban flooding. Therefore, it is very important to carry out regular culvert dredging operations.

[0003] Current culvert dredging operations are limited by space constraints, making it impossible for large culvert dredging robots to operate. Manual dredging is costly and labor-intensive, and the complex internal environment of culverts makes workers vulnerable to toxic and harmful gases. Therefore, it is imperative to develop a new culvert dredging system. Summary of the Invention

One end of the second rod is perpendicular to the first rod and connected to the lower end of the first rod. The second adjustment bracket includes a third rod arranged vertically and a fourth rod arranged horizontally. One end of the fourth rod is perpendicular to the third rod and connected to the lower end of the third rod. The upper end of the first rod is connected to the lower part of the first robotic arm, and the upper end of the third rod is connected to the lower part of the second robotic arm. The second rod and the fourth rod are arranged opposite to each other and are both located in front of the dredging robot.

[0011] The dredging sphere comprises a first dredging hemisphere and a second dredging hemisphere. Both the first and second dredging hemispheres are hemispherical, and multiple steel wires are arranged radially outward from both the first and second dredging hemispheres. Multiple first dredging hemispheres are arranged on the second rod, and multiple second dredging hemispheres are arranged on the fourth rod. The multiple second dredging hemispheres correspond one-to-one with the multiple first dredging hemispheres. In use, each adjacent first dredging hemisphere and one second dredging hemisphere are screwed together to form a dredging sphere.

[0012] An operation control system is located outside the culvert and is communicatively connected to the dredging robot. When the dredging robot enters the culvert, the operation control system controls the robot's movement, moves the first and second robotic arms, and drives the dredging sphere to perform culvert dredging.

[0013] Preferably, in the culvert dredging system, the dredging sphere is made of steel.

[0014] Preferably, in the culvert dredging system, both the first and second dredging hemispheres are hollow structures, and the resulting dredging sphere is a hollow sphere.

Controlled by a control system, the first and second robotic arms adjust their height and position, allowing the dredging ball to move and dredge. Driven by the first and second robotic arms, the dredging ball can reciprocate to any position for intensive dredging, preventing stubborn silt or debris from hindering cleaning. After dredging, the second and fourth rods, along with the dredging ball, gather and accumulate the silt at both ends of the culvert, facilitating its removal. Furthermore, this invention significantly improves the safety of dredging operations. No manual labor is required inside the culvert; workers only need to operate and remove silt at the ends, ensuring worker safety. The dredging is accomplished simply by setting up robotic arms, adjusting supports, and using the dredging ball. The equipment is ingeniously designed, highly flexible, and provides excellent dredging results, making it suitable for widespread use in urban areas.

[0038] The dredging robot has a first robotic arm 1 and a second robotic arm 2 symmetrically arranged on both sides along a direction perpendicular to its travel direction. The robot is equipped with a walking device at its bottom, preferably using wheels. The first robotic arm 1 and the second robotic arm 2 can move horizontally and forward and backward in the horizontal plane, and also move vertically up and down, enabling them to flexibly reach any designated position.

The second rod 102 and the fourth rod 202 are arranged opposite to each other and are both located in front of the dredging robot. The adjustment bracket is used to support the dredging ball and is connected to the robotic arm to move the dredging ball.

[0040] The dredging sphere comprises a first dredging hemisphere 103 and a second dredging hemisphere 203, both hemispherical in shape.

[0042] In use, this invention involves a dredging robot operating within a culvert. Through the control system, the first robotic arm 1 and the second robotic arm 2 adjust their height and position, allowing the dredging ball to move and dredge. Driven by the first and second robotic arms, the dredging ball can reciprocate to any position for high-intensity dredging, preventing stubborn silt or debris from hindering proper cleaning. After dredging, the second and fourth rods 102, along with the dredging ball, gather and accumulate the silt at both ends of the culvert, facilitating its suction and removal. Furthermore, this invention significantly improves the safety of dredging operations. No manual labor is required inside the culvert; workers only need to operate and suction the silt at the ends, ensuring worker safety.

When the dredging robot enters the culvert, the operation control system controls the robot's movement, moves the first and second robotic arms, and drives the dredging sphere to perform culvert dredging.

2. The culvert dredging system as described in claim 1, characterized in that, The dredging sphere is made of steel.

3. The culvert dredging system as described in claim 1, characterized in that, Also includes: An air purification system, which is installed on the dredging robot, is used to absorb and purify the gas in the culvert. An air compression system is installed on the dredging robot and located next to the air purification system. The air compression system is connected to the air purification system and is used to compress the purified air. A pressure tank is mounted on the dredging robot, located below the air purification system and the air compression system. The pressure tank is connected to the air compression system, and the operation control system is communicatively connected to the air purification system, the air compression system, and the pressure tank, respectively.

4. The culvert dredging system as described in claim 1, characterized in that, Also includes: A mud pump is installed at both ends of the culvert to discharge the dredged mud outside the culvert. The mud pump is communicatively connected to the operation and control system.

5. A method for dredging culverts, characterized in that, Includes the following steps: Provide a culvert dredging system as described in claim 1; The interior of the culvert was divided into multiple dredging sections. Working openings were installed at both ends of each dredging section, and several auxiliary working openings were installed in the middle area. Assemble the first and second adjustment brackets, and install the first and second dredging hemispheres onto the first and second adjustment brackets respectively. Then, connect the first and second adjustment brackets to the dredging robot. Each adjacent first dredging hemisphere and each adjacent second dredging hemisphere are screwed together to form a dredging sphere. The dredging robot enters the dredging section of the culvert through the working port. The operation and control system is set up above the culvert, and the dredging is carried out through the operation and control system.

6. The culvert dredging method as described in claim 5, characterized in that, It also includes the following steps: draining the dredged mud out of the culvert.
