Photovoltaic all-coverage fishery and photovoltaic generation complementation high-density fish culture system

Abstract

The invention discloses a photovoltaic all-coverage fishery and photovoltaic generation complementation high-density fish culture system. The photovoltaic all-coverage fishery and photovoltaic generation complementation high-density fish culture system comprises a photovoltaic generation system and a fish intensive culture system, wherein the photovoltaic generation system comprises a solar battery component, a photovoltaic support, an anti-thunder combiner box, an inverter integrated working box, a boosting transformer, an electric net, a charging and discharging controller, a storage battery and an inverter; the fish intensive culture system comprises a water lifting and oxygenation water pushing machine, bottom oxygenation equipment, pollution absorption equipment, an oxygenation water pushing zone, a culture zone, a faeces collection zone, a water quality purification zone, fish baffling grid mesh plates, a culture facility wall body and a water flow guiding facility; and the solar battery component is arranged on an upper part of a whole fishpond. By adopting the photovoltaic generation and fish open-type intensive culture integral composite production system, the utilization efficiency of a water surface can be effectively improved; the economic benefit of a unit water surface area is greatly improved; and an important means is provided for water area resource utilization in river network areas.

Description

technical field [0001] The invention belongs to the field of photovoltaic agriculture, and in particular relates to a photovoltaic full-coverage fish-light complementary high-density fish breeding system. Background technique [0002] In recent years, the construction of photovoltaic power plants in my country has developed rapidly. By the end of 2015, the installed capacity of photovoltaic power generation in China had reached 43.18 million kilowatts. However, the construction of photovoltaic power stations requires a large amount of land, and scarce land resources have become the biggest bottleneck in the construction of photovoltaic power stations in the central and eastern regions. There are tens of millions of acres of fishery waters in the central and eastern regions of my country. The combination of surface photovoltaic power generation and underwater aquaculture has become a new trend in the construction of photovoltaic power stations. Aiming at this new mode of com...

Problems solved by technology

However, there are obvious deficiencies in the current related patents: First, the photovoltaic panels intercept sunlight, which changes the light, temperature, dissolved oxygen and water quality of the pond water, changing the production environment of aquatic plants, phytoplankton and zooplankton, thereby affecting the production of aquatic plants, phytoplankton and zooplankton. The quality and output of fish cultured in the pond; second, because there are a large number of pillars used to fix photovoltaic panels in the pond, it is impossible to pull the net to fish, and only use the ground cage or fish in the fishway ditch after releasing the water, which is not only wasteful water resources, and the efficiency is low, and the catch is not clean; third, a large amount of excrement and residual feed from farmed fish enter the bottom mud and water body of the pond, affecting the water quality of the breeding water; fourth, the water area of ​​the pond is large, and it is difficult to control the environment of the fish breeding water. The application level of aquaculture facilities and equipment is low, and the output per unit area is not high
