Oxygenation robotic fish based on jet propulsion

Abstract

The invention discloses an oxygenation robotic fish based on jet propulsion. The oxygenation robotic fish comprises a sensing interaction module, an ascending and descending module, a power module, anoxygen concentration measurement module, a jet pump module, a robotic fish skeleton and a shell, The sensing interaction module comprises an ultrasonic sensor, a data receiver and a controller. The controller is connected with the ultrasonic sensor, the data receiver and the ascending and descending module through data lines. The jet pump module is installed in the middle of the robotic fish skeleton and comprises a driving fluid suction pipe, a working fluid suction pipe, a jet pump and a discharge pipe. Power can be provided for movement of the robotic fish while oxygenation is conducted through the jet pump; Oxygen can be accurately monitored and supplemented through cruising of the robotic fish in a net cage, and it is ensured that the oxygen concentration in the net cage meets the fish survival requirement. The oxygen concentration in water is measured actually through the oxygen concentration measurement module, oxygenation is conducted when oxygen deficit occurs, oxygenation isstopped when the oxygen concentration reaches the standard, and the breeding cost is saved.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, in particular to an oxygen-increasing robot fish based on jet propulsion. Background technique [0002] With the development of social economy, the development of marine resources is a national strategy and an inevitable trend. Underwater robots used in the development of marine resources are also receiving more and more attention. It can achieve rich functions through the collocation of various sensors, and has a wide range of applications. Large-scale deep-sea cage culture has been valued by many coastal countries in the world because of its advantages such as high production efficiency, good quality of adult fish, significant economic effect and low impact on the environment. However, due to the high density of fish cultured in cages, the oxygen consumption is very fast. If oxygen cannot be replenished in time, the lack of oxygen will lead to the death of large areas of fish. In o...

Problems solved by technology

However, due to the high density of cage cultured fish, the oxygen consumption is very fast. If the oxygen cannot be replenished in time, the lack of oxygen will lead to the death of large areas of fish.

In order to solve this problem, the existing technologies are mainly to place the cages in a suitable position for dissolved oxygen and good water flow exchange, install water jet generators to enhance water exchange, and use water pumps to inflate deep water, etc., but these technologies not only cannot Accurately supplement oxygen for hypoxic locations, and inject oxygen through water pumps, there will be waste of excess oxygen, which will increase the cost of cage culture
