TECHNICAL FIELD
[0001] The utility model relates to an aquaculture device, in particular to a full-time spotlight type solar heat collecting and warming device for an aquaculture greenhouse. BACKGROUND
[0002] The aquaculture greenhouse is a method for breeding aquatic plants and animals by using a large greenhouse structure, and its main feature is that it can be free from the influence of seasons and climate and can isolate diseases and pests to provide a stable breeding environment for the breeding of aquatic plants and animals.
[0003] However, due to low temperature in winter, the water temperature in the breeding pool in the greenhouse is still lower than the normal growth temperature of aquatic products, and if no electric heater is provided, the growth of aquatic products will be stagnant, and even frozen to death or frozen injury; the suitable water temperature for nitrification reaction is 20-30 DEG C, the nitrification reaction speed decreases below 15 DEG C, and the nitrification reaction completely stops when the water temperature is lower than 5 DEG C, and the suitable water temperature range for denitrification reaction is also 20-40 DEG C, and in winter, the nitrification circulating water needs to be heated by an electric heater to maintain normal operation, and the energy consumption is huge.
[0004] In order to reduce energy consumption, photovoltaic electric heaters have been used in the aquaculture industry, but in winter, the low temperature lasts for a long time, and the efficiency of the traditional photovoltaic power generation device is still less than 1 / 3 of that of thermal power, and there is a secondary conversion of energy during the period, and the energy conversion efficiency is lower, which is difficult to meet the energy consumption needs. The trough type solar heat collector uses a trough type parabolic reflector to focus the sunlight and reflect it onto a vacuum heat collecting pipe, and then transmits it through the glass outer pipe to the heat absorbing pipe, and the heat absorbing pipe surface is attached with a light spectrum absorbing coating to absorb sunlight and convert it into heat energy and transmit it to the heat transfer working medium in the inner pipe, and the vacuum layer between the heat absorbing pipe and the glass pipe can effectively prevent the conduction and convection heat loss of the air in the vacuum pipe, and at present, it has begun to be used in solar water heaters; but the nitrification circulating water contains impurities and is rich in bacteria, and if it is used in a water heater, scale and biological deposition layer will be formed in the pipeline, causing pipeline blockage; therefore, the solar water heater cannot be directly used for nitrification circulating water heating; and the light spot temperature after the light concentration of the trough type parabolic reflector is very high, and if the heat dissipation of the heat absorbing pipe is not good, the light spectrum absorbing coating will also be ablated; the vacuum heat collecting pipe is usually of an integral type, and once the heat absorbing pipe is ablated, the vacuum heat collecting pipe will be scrapped immediately. Especially, the solar water heater is arranged in the open air like the photovoltaic power generation device, and it also needs to prevent wind, frost, rain, snow, haze, hail, and is more affected by the weather, and the maintenance cost is higher.
