Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
The utility model relates to a kind of greenhouse by solar heat drencher system, as shown in Fig. 1 and Fig. 2, is comprised of water circulation system 1, sunlight board 2, plastic foil 3 and cistern 4 four parts; It is characterized in that: it is inboard that cistern 4 is positioned at the greenhouse north wall; Water circulation system 1 is comprised of the water pump 5 that is arranged in cistern 4, trunk line 11, branch pipe(tube) 12, flow straightener 13 and hollow billet road 14, water pump 5 tops are the trunk line 11 that vertical direction arranges, trunk line 11 connects the branch pipe(tube) 12 that horizontal direction arranges, branch pipe(tube) 12 belows connect flow straightener 13, the purpose that flow straightener is set is to make current more even, and flow straightener 13 belows link hollow billet road 14; The sunlight board 2 of hollow is positioned at top, north side, greenhouse, and the space of sunlight board 2 is along adverse grade direction from top to bottom; The lower end of sunlight board 2 is positioned at the top of bottom cistern 4, and be provided with the plastic foil 3(of the heat and moisture preserving that sunlight board 2 and cistern 4 can be sealed or open between the lower edge of sunlight board 2 and the outer of cistern 4 during winter, the outer of the lower edge of sunlight board 2 and cistern 4 plastic foil 3 by heat and moisture preserving is closed, can reduces the humidity in the greenhouse; During summer, the plastic foil 3 of the heat and moisture preserving between the outer of the lower edge of sunlight board 2 and cistern 4 rolled open, can increase the humidity in the greenhouse).
