[0002] In the prior art, the best temperature for aquaculture is generally between 18℃ and 25℃, but the temperature is low in winter, and the aquaculture water environment changes complexly, which is not conducive to the survival of aquatic organisms overwintering. Generally, farmers use heating measures such as greenhouses and heating water pipes to increase the temperature of fish ponds to improve the survival rate of aquatic organisms in winter. However, whether it is a greenhouse or the existing heating water pipes on the market, the energy consumption of winter heating aquaculture is relatively high, and the aquaculture cost is also relatively large, which is not conducive to the development of the industry. The heating measures for winter aquaculture mainly include heating measures and insulation measures. The commonly used winter fish aquaculture heating system works 12 hours a day, and the power consumption per hour can be more than 40kw, and the daily energy consumption can reach 480KW. The energy consumption is extremely high, and the aquaculture cost is also relatively large, which is not conducive to the sustainable development of the winter aquaculture industry. Summary of the invention

DETAILED DESCRIPTION

[0023] The specific technical scheme of the present invention is further described in detail below with reference to specific examples.

[0024] As shown in the figure, the present invention provides a fish pond winter aquaculture heating and constant temperature system, comprising an inner layer 100, and a layer of intelligent temperature regulating material is coated on the outer surface of the inner layer 100;

[0025] A heating system 300 having the same shape as the inner layer 100 is installed on the outer side of the inner layer 100 and covers 2 / 3 to 4 / 5 of the outer diameter of the inner layer.

[0026] The heating system 300 is connected to a power source and is used to heat the water flow. A current controller is also installed in the heating system 300.

[0027] The outer layer 200 is disposed outside the heating system 300 .

[0028] The heating system 300 includes a water suction pipe 310, a heating water pipe 330 and a water outlet pipe 320. One end of the water suction pipe 310 is connected to the heating water pipe 330, and the other end is connected to a water pump, and the water pump is placed in a water source.

[0029] The water outlet pipe 320 is made of stainless steel and is connected to the other end of the heating water pipe 330 .

[0030] The heating water pipe 330 includes a copper tube 331 having the same shape as the inner layer 100, a flexible heating film 333 wrapped around the copper tube 331, and a ceramic outer cover tube 332. The flexible heating film 333 is wrapped around the surface of the copper tube 331, with a wrapping area of ​​more than 20%, and is covered with an insulating ceramic outer cover tube 332 on the outside.

[0031] The intelligent temperature regulating material is a film of a phase change material of paraffin, polyethylene glycol and its derivatives, alcohols, esters and fatty acids. The phase change material is a paraffin phase change material or an alcohol phase change material blocked by a hydrogel to prevent the phase change material from leaking and losing its heat preservation performance.

[0032] The phase change material can absorb or release a large amount of latent heat at a nearly constant transition temperature.

[0033] The flexible heating film 333 may be a SiO2 / carbon nanotube electric heating film, which can perform electrical heating normally under high temperature conditions, thus avoiding the problem of ordinary heating films failing due to high temperature heating performance.

[0034] The outlet pipe 320 extends 10cm-30cm from the inner wall of the inner layer 100 of the fish pond, and is set at a height of 20-40cm from the water surface of the fish pond; and a water flow sensor is also installed at the water outlet end of the outlet pipe 320 to sense the size of the water flow. The current controller controls the overall power switch according to the size of the water flow, thereby improving the safety performance of the heating system.

[0035] The preparation method of the SiO2 / carbon nanotube electric heating film is as follows:

[0036] The carbon nanotube film is initially treated and then immersed in tetraethyl orthosilicate for a certain period of time, taken out, repeatedly cleaned and dried to obtain a SiO2 / carbon nanotube electric heating film.

[0037] The fish pond is also equipped with a water temperature sensor. When the water temperature in the fish pond reaches a preset value, the temperature sensor transmits a signal to the control system, cutting off the power supply, thereby realizing an automatic power-off function and stopping heating to prevent the water temperature in the fish pond from being overheated.

[0038] The constant temperature system provided in the embodiment of the present invention was used in a round pond experimental fish pond for testing.

[0039] The specific data of the experiment are: room temperature 10℃, water volume in the fish pond is 15L, the inner diameter of the fish pond is 50cm, the length of the heating copper tube is about 1.2m, the diameter of the heating copper tube is 3cm, the heating film is a 1cm*200cm strip wrapped around the heating copper tube, the water flow rate is 250L / h, the temperature rises by 1℃ in 1.5min, and the power of the heating system 300 is 440W.

[0040] After the water temperature in the fish pond reaches the set temperature, no insulation measures are taken and the water temperature in the fish pond is measured every 3 hours. The results show that from 0 to 10 hours, the temperature in the fish pond is maintained at 20℃-22℃, from 11 to 16 hours, the temperature in the fish pond is maintained at 18℃-20℃, and from 17 to 24 hours, the water temperature in the fish pond gradually drops to the original temperature.

[0041] Because the outer surface of the inner layer of the fish pond is covered with a thin film of phase change material, it can absorb or release heat. When the temperature of the fish pond is too high in summer, it can release heat to ensure that the temperature of the fish pond is maintained at 22℃-25℃; the addition of the phase change material film prolongs the constant temperature effect of the fish pond after one heating, and there is no need to set up additional constant temperature measures, which reduces the heat loss of the fish pond; after one heating reaches the set temperature and the power is turned off, the fish pond can maintain a temperature in the range of 18℃-25℃ for more than 16 hours.

[0042] The technical solution in the embodiment of the present invention is that the fish pond is set as an inner and outer double-layer structure, the outer surface of the inner layer 100 is covered with a layer of phase change material film, and a heating system 300 is arranged between the inner layer 100 and the outer layer 200. The heating system 300 has only 440w, and the energy consumption is extremely low. After heating to the set temperature, the power is cut off. The phase change material film can maintain the water temperature of the fish pond above 18°C ​​for 16 hours. The fish pond does not need to set up additional constant temperature measures. The constant temperature system of the present invention can reduce energy consumption by more than 30%, thereby reducing breeding costs.
