Embodiment Construction
[0013] Position the fry or shrimp incubator where it can get direct sunlight. The temperature and water temperature in the incubator are adjusted by solar heat conversion, without electricity and boilers for heating hot water.
[0014] Solar light-transmitting glass: glass tempered into a convex shape. Installed around the outermost layer and the top layer of the incubator.
[0015] Heat-absorbing surface: Made of copper, aluminum alloy, and steel, the outer fins are welded on the convex arc surface of the heat-absorbing surface perpendicular to the heat-absorbing surface, and the distance between each piece of the outer fins is the minimum mutual shielding of the orthographic projection. According to the material characteristics of the heat-absorbing surface, electroplating coating, electrochemical conversion coating, vacuum coating coating or paint coating are selected to play a good light-absorbing effect.
[0016] Outer fins: use the same material as the heat-absorbing s...

The invention provides a method for supplying heat sources in the hatching processes of fish fries and shrimp postlarvae by a solar thermal conversion technology. The method comprises the following steps of: storing absorbed solar energy by the solar thermal conversion technology, and supplying hot water by using a fin heat exchange tube; regulating the temperature to the optimum temperature for the hatching of the fish fries or the shrimp postlarvae; introducing the hot water into a tank body to serve as hatching water; arranging a heat insulating layer made of a heat insulating material at the periphery and the bottom to prevent heat of a heat collector from dissipating to ambient environments so as to improve the efficiency of the heat collector; arranging a black heat absorption and heat storage material on the heat insulating material, which has high light absorption amount and can be used for absorbing sunshine, converting the sunshine into heat energy and transmitting the heat energy to the inside to the greatest extent so as to increase the internal temperature of the tank body; and specially arranging a layer of light filter device layer on the innermost layer to effectively prevent the stimulation of light from adversely influencing the fish fries. By the method, the tank body of a fish fry and shrimp postlarvae hatcher is designed, a great amount of energy can be saved, the absorbed solar energy is converted into the heat energy, the internal temperature of the hatcher can be kept, and the hot water which is heated by the heat energy can be directly used as the hatching water after the temperature is regulated. The technology belongs to the fields of the utilization of solar high-temperature heat and the like for relieving the conventional energy shortage and reducing ecological and environmental deterioration.
Description
technical field [0001] The invention relates to a method of using solar heat conversion technology to provide a heat source for fish fry and shrimp hatching. It is a method of implementing heat preservation and using solar energy to assist other energy sources in heating, which can ensure the emergence rate of fish and shrimp and achieve solar energy. It has high heat storage efficiency, assists other energy sources, heats up quickly, and implements heat preservation. It belongs to the application field of high-temperature heat utilization of solar energy, energy conservation and environmental protection. Background technique [0002] During the hatching process of fry and shrimp fry, there are high requirements for water temperature. Generally, the hatching temperature of fry is required to be between 20 and 30°C. The temperature is an important prerequisite for ensuring the normal development of fry. If the temperature is lower than or higher than the optimum temperature r...
