Detailed Description

Referring to fig. 1-3, the part names are as follows: the solar energy heat-preserving greenhouse comprises a circulating water tank 1, a solar heat-collecting device 2, a radiator 3, a box body 4, heat-absorbing glass 5, a heat-absorbing mold 6, an aluminum plate 7, densely distributed water pipes 8, a heat-preserving layer 9, a water inlet pipe 10, a hot water outlet pipe 11, a hot water inlet pipe 12, a water outlet pipe 13, a plastic greenhouse 14 and a north wall 15.

Referring to fig. 1 and 2, the heating device for the fruit and vegetable plastic greenhouse comprises a circulating water tank 1, a plurality of solar heat collecting devices 2 (distributed along the interior of the greenhouse and connected in series) and a plurality of radiators 3 (distributed along the interior of the greenhouse and connected in series) which are connected through pipelines and control pipes (valves). Referring to fig. 2, the device is arranged on a north wall 15 of the plastic greenhouse 14, the front surface of the plastic greenhouse 14 is provided with a greenhouse film, and the front surface of the device faces the sunlight (the north faces the south), so that heat is taken conveniently. The device is provided with a control component, and can realize automatic control. The circulating water tank 1 (with water inlet and outlet, circulating pump and other conventional water heating devices) can be one or more according to the position, which is beneficial to storage.

Referring to fig. 3, the solar heat collection device 2 comprises a box body 4, heat absorption glass 5 (a light facing surface), a heat absorption mold 6 (sold in the market), an aluminum plate 7, water pipes 8 and a heat insulation layer 9 are attached to the inside of the box body 4 from the front side to the inside, the water pipes 8 are paved on the back of the aluminum plate in a tiled mode, and a water inlet pipe 10 and a hot water outlet pipe 11 are arranged at two ends of the collected water pipes 8. The heat absorption mold 6 absorbs sunlight to heat the aluminum plate 7 and conducts the sunlight to the densely distributed water pipes 8 behind the aluminum plate, water in the densely distributed water pipes 8 is heated, and finally the circulating water tank 1 exists to obtain hot water. The solar heat collecting devices 2 are arranged according to the area of the greenhouse, and the positions and the number are specific.
