Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is double layer hollow plastic film structures schematic diagram of the present utility model;

Among the figure, 1 overhead basis, 2 tops connect a structure, and 3 go along with sb. to guard him face, 4 greenhouse bodies, 5 north slopes, 6 Nan Po, 7 a main north slope, 8 double layer hollow plastic films, 9 thermal insulation quilts, 10 solar water heaters, 11 aluminium foil layers, 12 ventilation by forced draft mouths, 13 sunshade nets, 14 wet curtains, 15 cool water circulating pipe roads, the straight tilted supporter in north, 16 top, the southern arch support in 17 tops, 18 racks, 19 tracks, 20 north walls, 21 heat storing and heat preserving sheet material layers.

(5) embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises that overhead basic 1, top connects a structure 2, goes along with sb. to guard him face 3 and greenhouse body 4, north slope 5 elevations angle of greenhouse body 4 be 56 ° 19 ', the bevel angle on south slope 6 be set to 26 ° 34 ', go along with sb. to guard him face 3 and be made as arcuate surface, greenhouse body 4 is provided with heat-insulation system and cooling system, the north side north slope of greenhouse body 4 is set to a main north slope 7, and greenhouse body 4 is provided with outer covered structure.Heat-insulation system comprises the double layer hollow plastic film 8 that is covered in the face of going along with sb. to guard him 3 and north slope 5, double layer hollow plastic film 8 and top connect a structure 2 outer thermal insulation quilts 9 that are coated with, north slope 5 inboards hang solar water heater 10, and double layer hollow plastic film 8 inner layer films are aluminium foil layer 11.Cooling system comprises that being opened in overhead basic 1 four limits and top connects some ventilation by forced draft mouths 12 around the structure 2, goes along with sb. to guard him face 3 tops and top and connects on the structure 2 and be coated with sunshade net 13, and body 4 inside in greenhouse are provided with some wet curtains 14 and cool water circulating pipe road 15.Outer covered structure comprises the straight tilted supporter 16 in north, top and the southern arch support 17 in top, and the top connects on the structure 2 has constructed rack 18, and rack 18 is connected with track 19.A main north slope 7 comprises the north wall 20 that is arranged at a main north slope 7 north sides, and a main north slope 7 tops are equipped with heat storing and heat preserving sheet material floor 21.

Adopt a kind of energy-efficient Donges light greenhouse that connects of the present utility model, when designing again the ratio on slope, north and south and angle after overhead basic 1, unlike single Donges light greenhouse, be subjected to the restriction of ridge height and rise-span ratio, with the inclined-plane on south slope 6 carry to 26 ° 34 ', this is unapproachable in single Donges light greenhouse, if because sloping 6 floor projections in south are 12m, then its ridge height will reach 6m.The elevation angle of north slope 5 then reaches 56 ° 19 ', elevation angle (50 °) greater than north latitude 40 ° of regional spring, Autumnal Equinox solar noon sun, make north slope 5 inner faces except high noon in the Summer Solstice top do not meet in short-term light, all the other periods, season are met light entirely, have increased sun Optical Absorption and utilization.Connect the energy-efficient of Donges light greenhouse for implementing to cover outside the integral body to reach, to go along with sb. to guard him face 3 respectively to extending out out 2m, be connected to become south, east, three arches in west with the arch pole and go along with sb. to guard him face 3, both solved the technical barrier of whole outer covering, enlarged again area and the daylighting area of greenhouse culture.Substantially not increasing in the situation of investment, increased area under cultivation, relative reduce the greenhouse cost; Increased southern sloping 6 and gone along with sb. to guard him face 3 daylighting areas, the daylighting area that face 3 is gone along with sb. to guard him in east, west also increases by 50% by half, the angle of chamfer of this daylighting area reached 56 ° 19 ' near desirable lighting angle, all make the daylighting ability in this greenhouse have raising very large.The low thermophase covering and heat insulating of winter-spring season is by 9 insulations, add the heat storing and heat preserving of north wall 20 and a main north slope 7, north slope 5 He Nan, east, three in west being gone along with sb. to guard him the responsive to temperature position of face 3 has taked double layer hollow plastic film 8 to cover, inner layer film is aluminium foil layer 11, daytime, reflected sunlight improved indoor intensity of illumination, intercepted long sloping radiation night, maintain higher ground temperature, growth crop root, enhancing development.Utilizing north slope is that whole day is met light and is subjected to light except high noon in the Summer Solstice, photophase hangs solar water heater 10 and utilizes the hot water concurrent heating in north slope 5, utilize pipeline night to the greenhouse body 4 indoor benefit temperature, ensure safety in production, condition maturity and then satisfy crop to the needs of temperature, even carry out solar electrical energy generation, become passive-type production and be active environmental production.By these aggregate measures, guarantee the winter-spring season indoor and outdoor minimum temperature temperature difference 〉=30 ° of C, indoor minimum temperature 〉=12 ° C reaches safe and efficient production.Summer and autumn high light, hot stage covered with sunshade net 13, anti glare anti static coatings, cooling, its effect is better than the way (because can only play open-air effect like that) that adopts Full-open in Dutch greenhouse, simultaneously, in four limits of overhead basic 1, the top connects the south of a structure 2, north slope and east, ventilation by forced draft mouth 12 is established in the corresponding position of Xi Qiang, utilize natural wind to improve effect, cooperate wet curtain 14 coolings and 15 coolings of cool water circulating pipe road, maximum temperature in the holding chamber≤32 ° of C, day and night temperature 〉=10 ° C is not only and solves a production in summer difficult problem, but the raising production in summer reaches round-the-clock production.It is the large characteristics that the utility model is different from other attached-greenhouses that north wall 20, a main north slope 7 are arranged, overhead basic 1 protects the north wall 20 in single Donges light greenhouse true and the heat storing and heat preserving sheet material floor 21 that the top connects first on a structure, its existence not only has great role to the firm durable and wind loading rating of greenhouse body 4, and the ability of its insulation and the accumulation of heat of absorption sunlight also is irreplaceable.If utilizing it to set up in its north raises, edible seedling is cultivated facility or the buildings such as office, storehouse, it saves land, reduces the effects such as cost and raising usefulness will be more huge.By the straight tilted supporter 16 in top north, the southern arch support 17 in top and overhead basic 1, formed the skeleton that the top connects a structure 2 by lacing wire.At first be to connect a structure 2 to set up track 19, construct rack 18 at the top, Jiang Nan, east, three in west are uprightly gone along with sb. to guard him face 3 and are become arcuate surface, connect into a system and carried out outer covering with top rack 18, and thermal insulation quilt or sunshade net are positioned over body bottom, greenhouse.It is worth mentioning that, just for to carry out integral body outer cover just with three go along with sb. to guard him face 3 each to having extended out 2m, thereby in the situation that does not increase investment, enlarged area coverage, the angle of chamfer that to go along with sb. to guard him in addition face 3 is made as 56 ° 19 ', increased sun Optical Absorption and utilization.Simple in structure firm, easy to operate, time saving and energy saving, cost is low, coverage effect good.
