embodiment:
Below in conjunction with accompanying drawing, the present invention is described further:
The present invention relates to a kind of greenhouse by solar heat drencher system, as shown in Figures 1 and 2, formed by water circulation system 1, sunlight board 2, plastic foil 3 and cistern 4 four parts; It is characterized in that: cistern 4 is positioned at north wall inner side, greenhouse; Water circulation system 1 is made up of the water pump 5, main pipeline 11, branch pipe(tube) 12, flow straightener 13 and the hollow billet road 14 that are arranged in cistern 4, water pump 5 tops are the main pipeline 11 that vertical direction arranges, main pipeline 11 connects the branch pipe(tube) 12 that horizontal direction arranges, branch pipe(tube) 12 belows connect flow straightener 13, the object 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 while being provided with plastic foil 3(winter 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, the lower edge of sunlight board 2 and the outer of cistern 4 are closed by the plastic foil 3 of heat and moisture preserving, can reduce the humidity in greenhouse; When summer, the plastic foil 3 of the heat and moisture preserving between the lower edge of sunlight board 2 and the outer of cistern 4 is rolled and opened, can increase the humidity in greenhouse).
The consistency of thickness of the diameter in hollow billet road 13 and sunlight board 2, hollow billet road 13 can deeply enter in the space of sunlight board 2 of hollow.
As shown in Figure 3, the thickness that single sunlight board 2 thickness are 5-25mm(sunlight board can be set to 5mm according to actual needs, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 20mm, the different sizes such as 25mm, be advisable with 10-15mm), sunlight board length H is that 1-6m(can be set to 1m according to actual conditions, 2m, 3m, 4m, 5m, 6m etc., be advisable with 2-4m), the hollow space direction of sunlight board is along adverse grade direction setting from top to bottom, single sunlight board is longitudinally arranged side by side to arrange along adverse grade and forms overall sunlight board, the overall width L of north side, whole greenhouse sunlight board is less than greenhouse East and West direction length, can determine according to actual conditions.
The suitable for reading wide 20-150cm(of cistern 4 can be set to 20cm, 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 110cm, 120cm, 130cm, 140cm, 150cm etc. according to the width suitable for reading of the different cisterns of actual greenhouse size, is advisable with 50-100cm).
When the present invention uses:
Before and after the winter daytime sun can direct projection air themperature on the sunlight board of north side, greenhouse, in greenhouse while rising to 15-30 DEG C, start water pump, current in cistern enter in the space of sunlight board by main pipeline, branch pipe(tube), flow straightener and hollow billet road, current are slowly dirty in the space of sunlight board, form the cascade of the inclination of thin layer, then,, because lower end and the cistern of sunlight board have certain drop, can form again vertical cascade one in the lower end of sunlight board like this.Sunshine, by irradiating inclination cascade in sunlight board and vertical cascade in film, can improve heat and the temperature of water.Water in cistern, by the iterative cycles of water pump, can improve gradually water temperature and accumulate heat.Evening, when the air themperature in greenhouse drops to 5-20 DEG C, can open water pump and make water circulation, by tilting can make the thermal release in water with vertical cascade, improve the temperature in greenhouse, thereby realize the accumulation of heat of winter greenhouse, the effect that heats and be incubated.
In summer high temperature season, underground water is by the circulation of this system, can realize the effect of cooling, if open the heat and moisture preserving plastic foil between sunlight board and cistern simultaneously, can also increase the humidity in greenhouse, further reduce the humidity in greenhouse, can realize like this cooling and the humidification of Greenhouse in summer.
For the less demanding greenhouse of the illumination such as edible fungus culturing and aquaculture, this system also can all can be installed at positions such as the southern side in greenhouse, east side and west sides, thereby realizes accumulation of heat and insulation, the effect of cooling and humidification.
This greenhouse by solar heat drencher system of the application of the invention, improves in the winter time the heat of water, thereby has improved heating and heat-insulating property of greenhouse to make full use of solar energy; Can also reduce greenhouse temperature and improve chamber humidity in summer; Meanwhile, can also improve the environment conditioning ability in greenhouse, improve the productivity in greenhouse, reduce the consumption of the energy, realize low-carbon (LC) agricultural.
