Underwater patrol robotic fish

Abstract

The invention relates to the technical field of hydrological exploration, and discloses an underwater patrol robotic fish which comprises a robotic fish body, a power tail fin assembly is embedded in the rear end of the robotic fish body, a snorkeling device is installed at the position, close to the rear side of an ultrasonic detector, of the lower end of the robotic fish body, and propellers are installed on the rear sides of the two ends of the robotic fish body. The speed of the robotic fish in water can be controlled through the propeller and the power tail fin assembly, so that the robotic fish has the high swimming speed, meanwhile, the power tail fin assembly can adjust the balance of the robotic fish, steering or turning around of the robotic fish can be achieved by adjusting the angle between the propeller and the robotic fish body, and the robotic fish has flexible maneuverability; by adjusting the angles of the blades in the adjustable paddles, the angles of the blades adapt to the current water flow direction, the current water flow speed and the speed direction of the robotic fish, the robotic fish can have the optimal motion state, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of hydrological exploration, in particular to an underwater patrol robot fish. Background technique [0002] With the high development of society, more and more facilities and equipment are operating underwater. Over time, these equipment need to be inspected and maintained, for example, water tanks, sewer inspections, ocean oil pipelines, crossing rivers and rivers Pipeline inspection, maintenance of ship bottom, wharf, dam, underwater drilling platform, etc., and manual diving to underwater inspection, not only the workload is heavy, but also the risk factor is high, the labor efficiency is low, and it is difficult to do everything in the inspection , which requires the use of underwater patrol robot fish. [0003] A Chinese patent discloses an auxiliary bionic robot fish (authorized announcement number CN110065607B).

[0002] With the high development of society, more and more facilities and equipment are operating underwater. Over time, these equipment need to be inspected and maintained, for example, water tanks, sewer inspections, ocean oil pipelines, crossing rivers and rivers Pipeline inspection, maintenance of ship bottom, wharf, dam, underwater drilling platform, etc., and manual diving to underwater inspection, not only the workload is heavy, but also the risk factor is high, the labor efficiency is low, and it is difficult to do everything in the inspection , which requires the use of underwater patrol robot fish

[0003] A Chinese patent discloses an auxiliary bionic robot fish (authorized announcement number CN110065607B). The docking frequency of the existing bionic robot fish improves the working efficiency, but it cannot flexibly adjust the swimming speed, turn around or turn, so that different underwater environments cannot be realized, and it cannot float up and down at different angles. latent
