Underwater robot based on shape memory alloy wire driving

Abstract

The invention discloses an underwater robot based on shape memory alloy wire driving. The underwater robot is provided with a machine frame, an underwater camera is fixed to a top cover on the machine frame, an electric controller is arranged on the machine frame and located below the top cover, a balance weight adjusting block is arranged on the machine frame, leg connecting frames are fixed to the four corners of the machine frame respectively, and thighs are hinged to the leg connecting frames; shanks are hinged to the other ends of the thighs; a plurality of fins are hinged between the two shank arms; ratchet wheels and torsion springs are fixed on the shanks and the thighs; a shape memory alloy wire electrically connected with the electrical controller is arranged, one end of the shape memory alloy wire is fixed on the rack, the other end of the shape memory alloy wire is connected with a pull rope, the pull rope is hung on the ratchet wheel, a rope clamp is fixed on the pull rope close to the ratchet wheel, the other end of the pull rope is connected with a tension spring, and the other end of the tension spring is fixed on the rack. The underwater robot is advantaged in that underwater diving action of the robot is achieved through self weight, the shape memory alloy wire serves as a driving device to achieve floating and moving of the robot, the structure is simple and reliable, and therefore the underwater robot is small in overall size, low in production cost, low in operation noise and convenient to conduct underwater detection operation.

Description

technical field [0001] The invention relates to an underwater detection device, in particular to an underwater robot driven by a shape memory alloy wire. Background technique [0002] The ocean is an important part of the global ecosystem and a valuable asset for the sustainable development of human society. At present, mankind is facing problems such as shortage of land resources, population expansion, and environmental degradation. All countries have turned their attention to the ocean, which has huge potential. Among them, marine biological resources are one of the important resources in the ocean, but the current marine resource detection devices are too large and noisy. Using such detectors is not conducive to observing the most natural living conditions of marine life. In order to observe the most natural living conditions of marine life To reduce the impact on seabed organisms, there is an urgent need for an underwater detection device with small size, low investment...
