Underwater bionic robotic fish driven by fluid conveying pipe

Abstract

The invention discloses an underwater bionic robotic fish driven by a fluid conveying pipe. The underwater bionic robotic fish includes a fish head, a fish body, a dorsal fin, a tail fin, pectoral fins, a water sac, a water pump, a fluid conveying pipe system, a controller and a power supply. The interior of the fish body is a closed cavity, and the water pump, the controller and the fluid conveying pipe system are all installed in the cavity. Flutter occurs when the internal flow of a fluid conveying hose of the tail fin exceeds the critical flow velocity, so that the tail fin is driven to swing to provide power for the fish to move forwards. A fluid hose of the pectoral fins also flutters when the internal flow exceeds the critical flow velocity, so that the left and right pectoral finsswing up and down, and the steering of the fish can be controlled while the propulsion power is provided. The water storage capacity in the water sac is controlled by the water pump and the fluid conveying pipe system, and the weight of the fish body is increased or reduced so as to achieve the sinking and floating of the fish body. The required power for electrical equipment is provided by the power supply, and various motion forms of the bionic fish is controlled by the controller. According to the underwater bionic robotic fish driven by the fluid conveying pipe, the fish movement can be simulated, the disturbance to underwater creatures is reduced, and the risk of being trapped is reduced.

Description

technical field [0001] The invention belongs to the field of underwater detection robots, and more specifically relates to an underwater bionic robot fish driven by a delivery tube. Background technique [0002] At present, the development of underwater robots is quite common, and huge costs have been invested. These underwater robots are mainly used in the detection of underwater pollution sources, the survey of water quality, the search and rescue of marine accident ships, the observation of seabed fish and other fields. However, most of the existing underwater robots use motors to drive the propellers to push the robots forward, which inevitably has some defects, such as: the wake vortex caused by the rotation of the propellers greatly disturbs the environment and affects nearby fish schools; the complex ecological environment at the bottom is prone to Cause the propeller to be entangled by aquatic plants or waste, and cause the robot to be trapped at the bottom of the w...
