Underwater auxiliary rescue robotic fish and control system thereof

Abstract

The invention discloses an underwater auxiliary rescue robotic fish, and further discloses a control system of the underwater auxiliary rescue robotic fish. The underwater auxiliary rescue robotic fish comprises a fish head and a fish body, a steering adjusting assembly is arranged on the side, close to a first machine shell, of the bottom of a second machine shell, and a deviation mechanism is arranged on the side, close to the first machine shell, of the upper end of a bottom plate of a shell. A cross-shaped groove is formed in the upper end of the supporting plate to movably clamp a balance weight sliding block, a steel ball is arranged at the top end of the balance weight sliding block, a spring is arranged on the inner wall of the side, corresponding to the center of the groove, of the cross-shaped groove, the other end of the spring makes contact with the peripheral side wall of the balance weight sliding block, and when the spring is kept in a normal relaxation state, the balance weight sliding block is located in the center of the cross-shaped groove. Electromagnets are arranged at the upper ends of the supporting plates at the end openings of the tail ends of the cross-shaped grooves and electrically connected with a microcomputer control processing module in the second machine shell, and when the electromagnet on one side of the steel ball is selectively controlled to be powered on, the electromagnet obtains magnetic force to attract the steel ball to drive the balance weight sliding block to slide, so that the gravity center of the robotic fish deviates, and the robotic fish is helped to rapidly steer.

Description

technical field [0001] The invention relates to the technical field of rescue auxiliary equipment, in particular to an underwater auxiliary rescue robot fish and its control system. Background technique [0002] The robot fish, as the name suggests, is a fish-like machine made of materials, an autonomous robot fish equipped with chemical sensors, which can swim in the water for hours, and the robot fish is used to detect pollutants and draw a real-time three-dimensional map of the port, thus indicating What chemicals are currently present in seawater and where they are located. The development of this technology will increase the flexibility and adaptability of port authorities to monitor pollution from ships, other types of harmful pollutants and discharges of pollutants from underwater pipelines. In addition to benefiting surveillance operations in EU ports, this project could lead to important advances in robotics, chemical analysis, underwater communications and robotic...

Problems solved by technology

However, it is inconvenient for the existing robotic fish to turn, especially when they are impacted by the water flow in the flood. The steering resistance of the robotic fish in the flood is greater, so that it cannot perform better flexible operations; and most of the existing robotic fish are used for exploration and search. etc., mainly to provide accurate information for rescue operations, and cannot directly help the trapped
