[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] The utility model proposes a solar greenhouse heat storage and temperature regulation system. The heat collecting module 4 is composed of multiple U-shaped water bags connected end to end in sequence through quick-plug connectors and connecting pipes. The U-shaped water bag is filled with water. The surface of the U-shaped water bag is black, which is used to absorb heat under light to heat the water filled therein. The U-shaped water bag is embedded in a zero-shaped groove opened on the insulation board, and its side away from the insulation board is pressed against the frame of the greenhouse to ensure that it will not fall. At the same time, black heat-absorbing paint is also sprayed on the insulation board, which can increase the heating rate of the water inside the U-shaped water bag. When there is sufficient light during the day, the water in the U-shaped water bag absorbs heat and heats up. When the temperature drops at night, due to the large specific heat capacity of water, a large amount of heat can be released to adjust the temperature inside the greenhouse to avoid the temperature inside the greenhouse being too low.

[0016] When using a greenhouse in extreme areas or extreme weather, a water reservoir and a water pump can be set under or inside the greenhouse. By connecting water pipes, the heat collection module, water pump and water reservoir form a water circulation system. When there is sufficient light, the water circulation is used to absorb heat to increase the overall absorbed heat. When there is insufficient light, the internal temperature of the greenhouse is adjusted by releasing heat through the water circulation. At the same time, the water pump can switch the power supply of the storage unit and the mains. When the total amount of heat absorbed by light is insufficient, a heating pipe can also be added to ensure the heat release to avoid the temperature difference between day and night in the greenhouse affecting the growth of crops. At the same time, a temperature sensor is installed inside the greenhouse to monitor the temperature changes inside the greenhouse. At the same time, the water pump, heating pipe, temperature sensor and processing module are integrated into the system. The operation of the system is regulated by the linkage and control of the processing module equipment and the functions of data transmission, processing, and storage. The processing module can switch the power supply mode of the storage unit and the mains.

[0017] A liquid level sensor is installed in the water reservoir to monitor the changes in water volume and transmit the data to the processing module. When the water level change value is abnormal, it can be uploaded to the system in time to remind the staff to check and avoid water leakage.

[0018] When this solution is implemented, a central gateway linkage management system is used for control. The central gateway links the temperature sensor, liquid level sensor, heating tube and water pump. The power supply mode switches between AC power and storage unit through the central gateway. When AC power is available, AC power supply is preferred, and the circuit is controlled to charge the storage unit. When AC power cannot be supplied under special circumstances, the storage unit is used for power supply, and the storage unit uses a UPS power supply.
