Water surface floating photovoltaic power station cultivation device supplying oxygen for yellow croaker fry cultivation hotbed

Abstract

The invention relates to a water surface floating photovoltaic power station cultivation device supplying oxygen for a yellow croaker fry cultivation hotbed, and belongs to the new energy application technical field; the yellow croaker fry cultivation hotbed is placed close to the water surface floating photovoltaic power station; a buoyancy material layer is arranged below the water surface floating photovoltaic power station; solar cells, conductor wires, a controller and a diverter are arranged on the surface of the water surface floating photovoltaic power station; the current generated by sun light irradiating the solar cells passes the conductor wires and the controller, and is divided by the diverter so as to form three current flows; the first current flow enters a constant temperature device, thus keeping the constant temperature in a transparency plastic bedcover for yellow croaker fry growth; the second current flow drives an oxygen pump to supply oxygen in the air of the transparency plastic bedcover; the third current flow drives an electrolytic water device to electrolyze the water so as to generate oxygen, and the oxygen is supplied to a seedling growing water layer through an oxygen supply air pipe, an oxygen storage device and an oxygen supply air pipe, thus ensuring dissolved oxygen in the seedling growing water layer is bigger than 5 milligram / liter, so the oxygen pump and the oxygen supply air pipe commonly build an oxygen-rich environment.

Description

technical field [0001] The invention relates to a cultivation device for supplying oxygen to a yellow croaker fry cultivation hotbed by a floating photovoltaic power station on the water surface, and belongs to the technical field of new energy applications. Background technique [0002] Yellow croakers belong to the fish class and live in seawater with a pH value between 6.8 and 7.5. They are distributed in the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea. From March to June every year, yellow croakers migrate to the sea and spawn. After spawning, they are scattered in Search for bait along the coast, and swim to the deep sea to overwinter in autumn and winter. The yellow croaker has a flat and elongated body and is golden yellow. It is an important high-quality fish species. In the past 20 years, due to the impact of illegal fishing activities such as electric fish, poisonous fish, and fried fish, overfishing has shrunk yellow croaker resources an...

Problems solved by technology

Due to industrial production and coastal residents discharging pollutants into the offshore seawater, the water quality has declined, and the dissolved oxygen in the seawater has decreased, causing a large number of yellow croaker seedlings to die or have poor growth and development, which seriously affects the proliferation and release of yellow croaker fry and the output of yellow croaker.
