The technical solution of the utility model mainly comprises: the greenhouse by solar heat with heat storing and heat preserving effect is gone along with sb. to guard him structure, the specially designed pipe network system that contains many Pin roof truss of circulation current capable of circulation and be incubated the pond, and monitoring and control system.
Above-mentioned greenhouse is gone along with sb. to guard him structure and is included in the deployable front roof insulation covering 28 that covers front roof of the front roof 25, body of wall 26, rear roofing 27 and the night that cover the transparent plastic film composition on the roof truss.
Main composition as shown in Figure 1, the plane distribution situation of pipe network is as shown in Figure 2.
As shown in the figure, the greenhouse by solar heat roof truss evenly distributes with 1 meter spacing along greenhouse thing length direction, a common Donges light greenhouse has tens of Pin roof trusses, every Pin roof truss comprise one group of shape similar wind up 1 and lower edge 2, every group wind up 1 and the center line of lower edge 2 in a vertical plane.The roof truss of the present embodiment adopt the coating steel pipe material as roof truss wind up 1 and lower edge 2, middlely with reinforcing bar both are welded, form whole skeleton, wind up 1 and lower edge 2 connected into the pipeline that communicates by short tube 3 at highest point.1 the lower end of winding up of all roof trusses links to each other by bend pipe 4 with the water main 5 that is laid on the bottom, greenhouse, and water main 5 links to each other with immersible pump 11 in being installed in insulation pond 10 by water main 9 again; The lower end of the lower edge 2 of all roof trusses links to each other by bend pipe 6 with backwater main 7, and backwater main 7 is by in the return main 8 access insulation ponds 10.
So just consisted of connect that roof truss winds up 1, the water circulation flow cycle of lower edge 2 and water main 5, water main 9 and backwater main 7, return main 8 and insulation pond 10, immersible pump 11 etc.When immersible pump moved, current will circulate along the closed path in insulation pond 10 → immersible pump, 11 → water main, 9 → water main, 5 → bend pipe, 4 → 1 → short tube, 3 → lower edge, 2 → bend pipe, 6 → backwater main, the 7 → return main 8 that winds up → insulation pond 10.
The course of work in roof truss solar thermal collection system daytime is: when fine fair-weather daytime, after the solar radiation heat enters the greenhouse, because the thermal-arrest effect of greenhouse by solar heat closed construction, indoor air temperature begins to raise, simultaneously, winding up of roof truss 1 also is subject to the direct irradiation of the sun with lower edge 2 surfaces, and tube wall temperature raises.When automatic monitoring and control cabinet 19 monitor the indoor air temperature that transmits from indoor air temperature sensor 20 and are elevated to the signal of design temperature, control immersible pump 11 starts operation, make the water of insulation in the pond 10 continued to flow roof truss wind up 1 with lower edge 2, and after absorbing the heat that tube wall passes to, return again insulation pond 10.So move in circles, the water temperature of insulation in the pond constantly raise, insulation pond 10 since around the heat-insulation layer 29 of wall with well insulated, heat can be stored up preferably.When indoor air temperature drops to setting value, or when the temperature of water was higher in the insulation pond 10, monitoring was closed down immersible pump 11 automatically with control cabinet 19 automatically, to save power consumption.
The roof truss solar thermal collection system in the course of work at night is: especially connecting under the moon or the sleety weather night, because the heat radiation at the places such as front roof 25 in greenhouse, indoor air temperature reduces gradually, and indoor needs are heated.When automatic monitoring and control cabinet 19 monitored the indoor air temperature that transmits from indoor air temperature sensor 20 and be reduced to the signal of design temperature, control immersible pump 11 started operation, make water in the insulation pond 10 continued to flow roof truss wind up 1 with lower edge 2.Current carry out the solar heat of accumulating daytime with it and pass to tube wall from the insulation pond, by the heat convection effect of tube wall surface and room air, heat is passed to room air, realize the effect that inside greenhouse is heated.Because the heat release of roof truss is heated, and indoor air temperature is elevated to setting value, or when the temperature of water was low in the insulation pond 10, monitoring was closed down immersible pump 11 automatically with control cabinet 19 automatically, to save power consumption when indoor air temperature.
The utility model is collected and is accumulated unnecessary solar thermal energy in daytime at fine weather, heating when being used for night of greenhouse by solar heat and cloudy day or sleety weather.
In the daytime, the operation of roof truss solar thermal collection system, when making the water that is incubated in the pond 10 reach uniform temperature, also can be used as irrigation water or hot water for life.At this moment can be by closing back-water valve (BWV) 12, open hot water valve 14, can take hot water in the pipe network by hot-water branch 13.
Water in the insulation pond 10 can obtain automatically to replenish from the water system in greenhouse by ball-cock assembly 18.When the insulation pond needs cleaning, in the time of water wherein need being drained and changes, close feed water valve 15, open blowoff valve 17, the water in the insulation pond 10 can be drained.
In service at the roof truss solar thermal collection system, can be by flow and the pressure in flowmeter 21 and the water pressure table 22 observation pipe network, observe the water temperature that is incubated in the ponds 10 by pond thermometer 23, the temperature after flowing through from roof truss by return water temperature meter 24 observation current.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
