Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of dredging equipment, especially relates to a dredging robot and dredging robot system. BACKGROUND

[0002] In the current underwater dredging field, the dredging robot for the scene of inverted siphon pipe, pipe culvert and the like mainly adopts hydraulic drive mode, and this drive mode has two main forms: one is that the hydraulic system is directly installed on the body of the dredging robot, although this mode can provide powerful power output, but at the same time, it also leads to the significant increase of the volume and weight of the dredging robot, which limits its application in the pipe culvert and the complex water environment to some extent, and the larger volume and weight not only make transportation and deployment difficult, but also affect the flexibility and passability of the robot in the narrow or obstacle-rich water area; one is that the hydraulic power station is placed on the water surface, and the dredging robot is connected with the hydraulic power station through the hydraulic pipeline, and this separated design is usually suitable for short-distance dredging operation, when long-distance dredging operation is needed, this design will encounter a series of problems, first, the longer hydraulic pipeline will increase the weight of the system, which not only increases the difficulty of transportation and deployment, but also may cause the transmission efficiency of the hydraulic system to be reduced, second, the long-distance hydraulic pipeline may cause the action response speed to be slow due to pressure loss, which affects the efficiency and effect of the dredging operation, in addition, the maintenance and fault elimination of the hydraulic pipeline will become more complex and difficult. Therefore, using the hydraulic drive mode, whether it is installed on the body of the dredging robot or the separated hydraulic power station to control the dredging robot, there are many problems, and adopting the full-electric drive mode becomes a more ideal solution.
