Mechanical grabbing device for underwater robot

Abstract

The invention discloses a mechanical grabbing device for an underwater robot. The device comprises a protective frame, a rotating shaft is arranged on one side of one cushion disc in a penetrating mode, a first motor is fixedly arranged at one end of the rotating shaft, a supporting shaft is fixedly arranged at the other end of the rotating shaft, a groove is formed in the middle of one end of the supporting shaft, supporting sleeves are rotationally arranged in the middles of the two sides of the inner wall of the groove correspondingly, and a mechanical arm is fixedly arranged at the output end of the first electric telescopic rod. According to the mechanical grabbing device for the underwater robot, the orientation position of the whole grabbing structure can be changed by starting a first motor, then a second motor is started, a mechanical arm can stretch through rotation between a supporting sleeve and a groove, and therefore the grabbing area of the mechanical arm can face a grabbed substance; and the distance can be adjusted by starting the first electric telescopic rod to get close to the substance for grabbing, the grabbing precision is improved, and therefore the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of underwater exploration, in particular to a mechanical grasping device for an underwater robot. Background technique [0002] The traditional underwater robot mainly controls and detects it through smart chips and remote detection devices, so that it can be launched into the water to pick up underwater materials, and the underwater robot is also called an unmanned remote control submersible. The extreme operation robot, the underwater environment is harsh and dangerous, and the depth of human diving is limited, so the underwater robot has become an important tool for the development of the ocean; [0003] In the prior art, when designing and manufacturing the mechanical grasping device for underwater robots, most designers will pay attention to the clamping strength of the design device, so that it is difficult for the device to pick up and clamp the grasped items underwater. Falling, causing the second d...

Problems solved by technology

[0003] In the prior art, when designing and manufacturing the mechanical grasping device for underwater robots, most designers will pay attention to the clamping strength of the design device, so that it is difficult for the device to pick up and clamp the grasped items underwater. Falling, causing the second dive to grab, but when the device is exploring underwater for a long time, if the upper end of the grabbing area of ​​the device does not have the characteristics of rotation and expansion, the grabbing area may be too small to affect the grabbing efficiency , thereby reducing the practicality of the device
