Complex production system integrating photovoltaic power generation and open-air fish intensive aquiculture

Abstract

The invention discloses a complex production system integrating photovoltaic power generation and open-air fish intensive aquiculture. The complex production system integrating photovoltaic power generation and open-air fish intensive aquiculture comprises a photovoltaic power generation system and a fish intensive aquiculture system. The photovoltaic power generation system comprises a solar cell module, a photovoltaic support, an anti-thunder combiner box, an inverter integrated work chamber, a boosting transformer, a power grid, a charging and discharging controller, a storage battery and an inverter; the fish intensive aquiculture system is surrounded by a water area boundary dam, and comprises a water lifting and oxygen increasing water-pushing machine, a bottom oxygen increasing device, an air ventilating system, an oxygen increasing water-pushing area, an aquiculture area, a fecal collection area, a water quality purification area, a fish screen mesh plate, an aquaculture facility wall body and a current deflecting facility. According to the complex production system integrating photovoltaic power generation and open-air fish intensive aquiculture provided by the invention, the water surface utilization efficiency can be effectively improved, the economic benefit of a unit water surface area is greatly improved, and an important way is provided for water-area resource utilization in river crossed areas.

Description

technical field [0001] The invention belongs to the field of photovoltaic agriculture, and in particular relates to an integrated composite production system of photovoltaic power generation and fish open-air intensive cultivation. 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. Aim...

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
