Abstract

The invention relates to the technical field of unmanned ship equipment, in particular to a high-success-rate rotary excavation type sludge sampling device based on an unmanned ship. Comprising a frame, a hoisting rope is connected to the upper end of the frame, a digging claw is rotationally arranged on the frame, a sealing cover is arranged at an opening of a claw cavity of the digging claw, and the end, away from the digging claw, of the sealing cover is rotationally fixed to the frame; a sealing box is fixed on the frame, a driving motor is arranged in the sealing box, a driving shaft is arranged on the sealing box in a penetrating manner, the driving motor is in transmission connection with the driving shaft, and the driving shaft is in transmission connection with the digging claw; the device further comprises a spring, one end of the spring is connected to the side, away from the rotating center, of the sealing cover, the other end of the spring is fixed to the frame, and the sealing cover is pressed at the opening of the digging claw through elastic force of the spring. Sampling, overturning and sealing are completed through one driving device, a control system is simple, it can be guaranteed that sampled sludge is not washed away by water flow, and the sampling efficiency and the sampling success rate are improved.

Description

technical field [0001] The invention relates to the technical field of unmanned ship equipment, in particular to a high-success rate rotary excavation type sludge sampling device based on an unmanned ship. Background technique [0002] An unmanned ship is a fully automatic surface robot that can navigate on the water surface according to preset tasks with the help of precise satellite positioning and self-sensing without remote control. The English abbreviation is USV. Water quality testing and underwater silt sampling through unmanned ships are an important field in the application technology of unmanned ships. [0003] For example, the Chinese patent publication number is: CN208902462U, which discloses a dual-grab layered sludge sampling device based on an unmanned ship. The existing sludge sampling grabs are usually set upside down. After the grab grabs the sludge , is still upside down and the opening mouth is not sealed. Due to the complicated bottom conditions, there ...
