Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Among the figure, 1 is air bleeding valve, and 2 is water supply tank, and 3 is rectangular tube, and 4 is the hollow girder, and 5 is underground piping, and 6 is the skeleton hollow tube, and 7 is flowmeter, and 8 is tubing pump, and 9 is hollow cross, and 10 is underground trunk line, and 11 is ground surface, and 12 is the back wall, and 13 is vertical tube.In the present embodiment, hollow girder 4 is a steel pipe with hollow cross 9, and said rectangular tube 3 is a plastic tube with underground piping 5, in actual production, also can select other materials for use, like steel pipe.

The present invention utilizes the insulation of Keelof green house water-filling; Improve nocturnal temperature in the greenhouse; Main branch two-part structure: the one, structure as shown in Figure 1, the hollow girder 4 of highest point in the greenhouse is communicated with many hollow cross 9 on it in (among the figure letter drawn part hollow cross 9); The bottom of many hollow cross 9 is communicated with a corresponding end that is embedded under the face of land, greenhouse 30-60 centimetre many underground pipings 5 respectively; The other end of underground piping 5 (the north) is pooled to a underground trunk line 10, and is coupled logical, and this underground trunk line 10 is communicated with the circulation pipe network system that makes skeleton form circulation with the hollow girder 4 of greenhouse ridge eminence through a vertical pipeline.Water-filling in this circulation pipe network makes water circulation through a tubing pump 8, and flowmeter 7 is used to measure the water yield, when ducted water is lower than usage level, carries out moisturizing through water supply tank 2.When having unnecessary gas in the pipe-line system, open air bleeding valve 1 unnecessary gas is discharged.Through regularly the circulating pump 8 of water circulation in skeleton steel pipe and the plastics underground piping being opened; Be stored in the hydro-thermal amount in the skeleton steel pipe underground daytime; At night heat is discharged; So just can improve nocturnal temperature in the greenhouse, the water circulation direction is referring to arrow logo (referring to Fig. 1, Fig. 3) among the figure; The 2nd, like Fig. 2, structure shown in Figure 4, Hou Qiang is provided with the plastics rectangular tube 3 of a plurality of water-fillings in the greenhouse, and each plastics rectangular tube 3 connects to form square by four plastic tubes; In two plastic tubes that make progress perpendicular to ground, in the back wall that vertically is installed on the greenhouse, an other inner surface at the back wall; Plastics rectangular tube 3 is connected on the East and West direction hollow steel tube (being hollow girder 4) through a vertical tube 13; Through the variation Natural Circulation of water temperature, be stored in body of wall inside to the heat on wall surface daytime, discharges the temperature that increases in the greenhouse night; The direction of arrow is the direction that daytime, store heat time heat was transmitted among the figure; When the plastics rectangular tube is to the surface of wall release heat in the night body of wall, the direction of transfer of heat opposite (referring to Fig. 2, Fig. 3, Fig. 4), experiment proof; The setting of this rectangular tube can reach force request, can maximally utilise heat energy again.

Broken line among Fig. 3 in the arc roof has indicated steel bar or the iron wire metalloid goods that connect fixation.In the present embodiment, a hollow cross 9 is respectively established in the top and bottom on arc roof, has increased heat energy and has gathered emission surface, can also increase frame strength.

Can be known that by Fig. 2 hollow girder 4 is parallel with underground trunk line 10, the axis of the axis of described hollow cross 9 and the underground piping that is connected with it 5 makes compact conformation like this in a vertical plane, rationally distributed.

Thick black lines among Fig. 4 is represented the rectangular tube that four pipes are formed, and wherein leans on a pipe of greenhouse inner wall surface to communicate with vertical tube 13.The distance of (comprising two columns) is the thickness of back wall between two columns.

This greenhouse by solar heat is installed simple, after Installation and Debugging are good, as long as regularly the circulating pump of water circulation in skeleton steel pipe and the underground plastic tube is opened.This greenhouse by solar heat has been obtained in test good effect, compares with contrast and can improve temperature 1.5～2 degree.

Steel pipe in the foregoing description also can use other metal tubes to replace, and said plastic tube can replace with metal tube.

The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
