Referring to fig. 4, a third embodiment of the present invention is based on the previous embodiment, and is different from the previous embodiment in that: the greenhouse heat storage system 200 further comprises a fan bracket 203, and the fan bracket 203 is located outside the phase-change heat storage system 300.
Specifically, the fan bracket 203 is arranged above the inside of the greenhouse and is arranged on the periphery of the heat insulation layer 301, and the fan bracket plays a role in fixing the heat storage fan 201 and the temperature sensor.
The working principle of the invention is as follows: the invention utilizes the wind power heating device to convert wind energy into heat energy, and combines the active heat storage device to store the surplus solar energy in the greenhouse in the rear wall heat storage pile, and when the temperature in the greenhouse is reduced, the heat is dissipated into the greenhouse through the underground heat exchange system.
Wherein, wind-force blade 101 rotates with the wind, and transmission shaft 102 drives fan agitator 103 to rotate, through stirring friction heating heat storage pile 302, whole heat storage pile 302 is closely wrapped up by heat preservation insulating layer 301. Wind force detector 501 in control system 400 is used to monitor wind force intensity and thereby control the shutdown and startup of wind heating system 100.
The temperature sensor 502 is installed in the greenhouse to monitor the temperature change of the greenhouse in real time. When the temperature in the greenhouse is higher than a set value, the sensor feeds a signal back to the control system 500, the control system 500 acts on the greenhouse heat storage system 200 to work, the greenhouse heat storage system 200 takes air as a medium, the heat storage fan 201 sends hot air into the heat storage pile 302, the heat storage pile 302 exchanges heat through the first heat exchanger 202 of the heat storage fan 201, and the heat is stored; when the temperature in the greenhouse is lower than a set value, the temperature sensor 502 feeds back a signal to the control system 500, the control system 500 acts on a circulating water pump, namely a water pump 405 to work, the whole underground heat exchange system 400 adopts water circulation and exchanges heat with the heat storage pile 302 through the second heat exchanger 401, heated circulating water enters the water tank 404 through an underground buried pipe, namely a first pipeline 402a, the two ends of the first pipeline 402a are provided with water collecting headers 403, the number of the first pipelines 402a is set to be a plurality, and the heat exchange system is only one embodiment with reference to fig. 3 and is not limited to 5 first pipelines 402 a. The first pipeline 402a exchanges heat with soil, cooling water enters the water tank 404, the water tank 404 can also be used as an irrigation water storage device, and circulating water returns to the second heat exchanger 401 through the water pump 405 to exchange heat.
