Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The working range of the robot of the present invention is 0-10m underwater. The specifications of the robot are (length x width x height): 6000×2500×2400mm, the weight is 1500kg, and its main material is 316L stainless steel to reduce the corrosion of water on the robot. It is a kind of dredging operation suitable for lakes, urban and rural rivers, and fish ponds with a water depth of 0-10m.

[0019] combine Figure 1 to Figure 4 , a dredging robot for underwater dredging operation of the present invention consists of a main body frame 1, a leg hydraulic cylinder 2, a leg 3, a pin shaft 4, a limit block 5, a foot 6, an abdomen support plate 7, a support leg 8. Support column 9, connector 10, abdominal hydraulic cylinder 11, heave hydraulic cylinder 12, swivel frame 13, swing hydraulic cylinder 14, forearm truss 15, mud scrap...

Abstract

The invention provides a dredging robot for underwater dredging operation. The dredging robot comprises a main body frame, supporting legs, supporting leg hydraulic cylinders, an abdominal supportingplate, a belly hydraulic cylinder, a forearm truss, a rotating frame, a heaving hydraulic cylinder, a swinging hydraulic cylinder, a mud shoveling plate, a mud pump, a hose, a cutter suction mechanismand a buoyancy adjusting mechanism, wherein the walking action is completed by means of the four supporting legs and the belly supporting plate of the dredging robot; sludge can be directly cleaned at the water bottom; the dredging robot can work in more complex terrains; the supporting legs swing forwards in a supporting state of the abdominal supporting plate, the supporting leg hydraulic cylinders enable the gravity center of the robot to move forwards in the supporting state of the supporting legs, and the periodic movement enables the dredging robot to complete walking action. By controlling the telescopic length of piston rods of the heaving hydraulic cylinder and the swinging hydraulic cylinder, the dredging frame can rotate within a certain angle range, and the working range of the cutter suction mechanism is enlarged; and the buoyancy adjusting structure changes the weight of the robot by controlling the volume of water in the water ballast tank, so that the robot sinks or floats in the water.

Description

technical field [0001] The invention relates to an underwater robot used in dredging operations of lakes, urban and rural rivers, and fish ponds, in particular to a dredging robot used in underwater dredging operations, which belongs to the field of special robots. Background technique [0002] There is a large amount of silt in the bottom of lakes, urban and rural rivers, and fish ponds. The silt not only affects the water quality but also causes a large number of fish deaths. The main equipment currently used for dredging operations includes water dredging ships and underwater dredging equipment. The water dredging ship extracts sludge through a mud pump fixed on the ship and a hose connected to the mud pump at one end and the other end is fixed at the bottom of the water. However, the water dredging ship itself has great limitations, and the underwater mud is not cleaned thoroughly. At present, the underwater dredging equipment is mainly a crawler dredger, which can clea...
