Moreover, the nutrient solution is located in the cultivation device. Even if the overall temperature in the greenhouse is cooled, it cannot be reflected on the nutrient solution in time, so the temperature of the nutrient solution cannot be cooled in time, especially in summer, because the temperature of the nutrient solution is too high and cannot be cooled in time. , will affect the growth of crops, and it is easy to breed bacteria, which will affect the composition of nutrient solution
If the cooling device is further installed directly for the nutrient solution, the cost will be greatly increased

[0032] see figure 1 , figure 1 The nutrient solution cooling system 100 provided for the first example of this embodiment, the nutrient solution cooling system 100 is used to provide the nutrient solution required for the growth of the plant 10, and the plant can be a plant grown in deep liquid culture, or it can be Plants grown without soil. The nutrient solution cooling system 100 includes: a liquid supply pool 20 , a cold storage 30 , a first temperature detection device 40 , a flow control device 50 , a water outlet pipe 14 and a water inlet pipe 16 .

[0033] The liquid supply pool 20 is used to accommodate the nutrient solution, and the first temperature detection device 40 is disposed in the liquid supply pool 20 and used to detect the temperature of the nutrient solution contained in the liquid supply pool 20 in real time. A first pipe 12 is provided between the liquid supply pool 20 and the plant 10 , and the liquid supply pool 20 supplies nutrient solution to the p...

[0043] see figure 2 , figure 2The nutrient solution cooling system 200 provided in the second embodiment of the present invention, the structure of the nutrient solution cooling system 200 provided in the second embodiment is basically the same as that of the nutrient solution cooling system 100 adopted in the first embodiment, the difference is that , the nutrient solution cooling system 200 further includes a second temperature control device 60 and a second pipeline 80 .

[0044] The second temperature control device 60 is arranged at the liquid outlet end of the cooling pipeline 32 .

[0045] The second pipeline 80 is branched from the water inlet pipe 16 and leads to the plant 10, and the second pipeline 80 is provided with a fourth control valve 80a.

[0046] Moreover, the water inlet pipe 16 is provided with a third control valve 160 , and the third control valve 160 is used to control whether the nutrient solution enters the liquid supply pool 20 through the water ...

Abstract

A nutrient solution cooling system comprises a nutrient solution supplying pool, a first pipeline, a cooling store, a solution outlet pipe, a cooling pipeline, a first control valve and a second control valve, the nutrient solution supplying pool directly supplies nutrient solution to plants directly through the first pipeline, the solution outlet pipe is connected with the nutrient solution supplying pool, the cooling pipeline is positioned inside the cooling store, the first control valve is used for controlling the nutrient solution to flow in the first pipeline, the second control valve is used for controlling the nutrient solution to flow in the cooling pipeline, the cooling pipeline is connected with the solution outlet pipe, and the nutrient solution can flows into the cooling pipeline through the solution outlet pipe and then be transferred to the plants after being cooled. When the first control valve is turned on and the second control valve is turned off, the nutrient solution is directly transferred to the plants from the nutrient solution pool through the first pipeline; and when the first control valve is turned off and the second control valve is turned on, the nutrient solution flows into the cooling pipeline to be cooled before being transferred to the plants.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation of plants, in particular to a nutrient solution cooling system. Background technique [0002] Greenhouse (greenhouse), also known as greenhouse. A facility that can transmit light, keep warm (or warm), and be used to grow plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions. [0003] Greenhouse planting uses soilless cultivation technology, which requires strict temperature control, especially the temperature control of the nutrient solution supplied to plants; the requirements for greenhouse eq...
