Water constant temperature system of self-adjusting culture pond

Abstract

The invention relates to a water constant temperature system of a self-adjusting culture pond, which comprises a culture pond (1), a constant temperature pump (2), a heat exchanger (3), a temperature dynamic detection and analysis control device (4), a water temperature probe (5) and a water circulating pump (6), wherein, the heat exchanger (3) is connected between the culture pond (1) and the constant temperature pump (2) through a pipeline; a pond water temperature signal detected by the water temperature probe (5) is transmitted to the temperature dynamic detection and analysis control device (4) for analysis and processing of the temperature signal; a control signal is output and transmitted to the constant temperature pump (2) for controlling operation of the constant temperature pump (2); the constant temperature pump (2) is an air energy heat pump; and the water circulating pump (6) is connected between the culture pond (1) and the heat exchanger (3). The water constant temperature system of the self-adjusting culture pond has the advantages of simple structure, low energy consumption, safety and reliability.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a water temperature control system, in particular to a self-adjusting water constant temperature system for aquaculture ponds. Background technique [0002] At present, many farms on the market need to maintain a constant temperature of the pool water during the fry (or other aquatic products) cultivation stage. The temperature of the pool water is generally 23-25 ​​degrees, but it is difficult for the water temperature to meet this demand. When the water temperature is low, electricity is mainly used. Heating is used for auxiliary heating, and cooling tower is used for cooling when the water temperature is high. However, the above-mentioned constant temperature method has the following disadvantages: [0003] 1. When heating the pool water with electric heating, it consumes a lot of energy at this time, and the operating cost is very high. At the same time, when the electric ...

AI Technical Summary

Problems solved by technology

[0003] 1. When electric heating is used to heat up the pool water, the energy consumption is very large at this time, and the operating cost is very high. At the same time, electric leakage may occur when the electric heating is damaged.

[0004] 2. When the water temperature is high, the cooling tower is used for cooling. When the external environment is high, the cooling tower cannot reduce the water temperature to the required range. At the same time, when the water is cooled by the cooling tower, the pool water will still be in contact with the external environment. Pool water may also be polluted

[0005] 3. The water temperature does not reach the required range, which is not conducive to the development and growth of fry, and also reduces the survival rate of fry
