Abstract

The utility model relates to an asymmetric continuous crossing type energy-saving greenhouse. The utility model is composed of arch frames, a support connecting frame, a top surface, etc. The utility model is characterized in that the greenhouse forms the continuous crossing type; the greenhouse is composed of the connection of two to five antisymmetric arch frames; upright posts are connected by a transverse draw rod and a longitudinal draw rod; a transverse beam is arranged on the upper end of the transverse draw rod; both ends of each arch frame are respectively fixed on the transverse beam; a roofing angle alpha is 23.5 + (local latitude-40) * 0.5 plus or minus 3 DEG. The theoretical light inlet rate of the main season is guaranteed to achieve more than 95 %. Compared with the prior art, the utility model has the advantages of unique structural design, low operation cost, high utilizing rate of the solar energy, low energy consumption, etc. The utility model is suitable for flat grounds, steep lands and terraces.

Description

The asymmetric straddle type energy saving greenhouse that connects

The utility model is a kind of asymmetric straddle type energy saving greenhouse that connects.

In the prior art, the version in China greenhouse mostly is that on a small scale single structure of symmetric figure has only about 1/100 of Holland, and the equipmentization degree is low, and environment regulating power and means are poor, output about 7-5 kilogram/m that fluctuates on low-level ², be the 1/8-10 of Holland, production efficiency is low; Owing to weather conditions, the huge contrast of the market demand has caused investment big, takes in little significant wastage, is not easy to promote the use of in China though external greenhouse facilities is advanced.

The utility model overcomes the weak point of prior art existence and a kind of light angle science is provided, and directly light-receiving area is big, high insulating effect, the asymmetric straddle type energy saving greenhouse that connects that scale is moderate.

The utility model is to realize like this, joint formula energy greenhouse is striden by asymmetric company, comprise bow member, supporting link, end face, it is characterized in that the greenhouse is even straddle type, be formed by connecting by 2-5 asymmetric bow member, column and column laterally between is connected by girt, vertical between by vertical pull bar connection, crossbeam is contained in the upper end of girt, and the two ends of every group of bow member are separately fixed on the crossbeam.Every company of straddle type greenhouse structure of company strides 3-5 and strides, and single span is a 6-8 rice, and the difference in height in every greenhouse is a 0.5-1.5 rice, and the greenhouse scale is between 1500-4500 rice.

The angle α roofing angle α of line that the peak B of bow member described in the utility model and the C on front column top are ordered and horizontal plane is 23.5+ (local latitude-40) * 0.5 ± 3 degree; The A point line on peak B and rear column top and the angle backhouse angle β of horizontal plane are the 35-45 degree.The light angle of roofing is according to residing geographical position, various places and definite, can guarantee main season (day long more than 11 hours) theory advance the light rate and reach more than 95%.

The radian that the master on the utility model roof advances light is that the perpendicular bisector of the front column top C line of ordering upwards intercepts 25-40 centimetre.

Can set up heat-insulation layer on cross-tie of the present utility model and the longitudinal tie, reduce area of dissipation and heating volume significantly, energy-saving effect reaches 65%-70%.

With reference to the accompanying drawings embodiment is further described, present embodiment is an example with the domestic greenhouse of building of Shanxi Taigu County, and total span 20.2 meters (6 meters of single spans, 6 meters of the standard widths of a room in an old-style house) total lengths in north and south are 100 meters, and the gross area is 2050 meters ²Determine roofing angle α=22.25 degree, backhouse angle β is 45 degree, and roof radian height is 27 centimetres.The arch of bow member 1 is made according to the angle of determining, connecting link pin 6 is equipped with in the upper end of column 5, the spliced eye that is complementary with connecting link pin 6 is equipped with at the two ends of cross-tie 3 and longitudinal tie 4, bow member connecting rod 8 links to each other with bow member by bow member connector 7, column 5 and column 5 laterally between be connected by cross-tie 3, connect by longitudinal tie 4 vertically, crossbeam 2 is contained in the upper end of cross-tie 3, the two ends of every group of bow member 1 are separately fixed on the crossbeam 2, add a cover the roof on the bow member, cross-tie 3 is set up heat-insulation layer 9 with the top of longitudinal tie 4, and the asymmetric straddle type energy saving greenhouse that connects can build up according to said method.

The utility model compared with prior art has the following advantages, and 1, high in technological content, the structural design uniqueness combines The many factors such as the national conditions of China, national power, the investment capacity, climatic characteristic; 2, operating cost is low, the solar energy utilization ratio height, Power consumption is few, simultaneously so that machinery, cooling system use amount and running expense greatly reduce; 3, construction cost is low, the building material Expect whole nationalization, wall area reduces 50%, only is the 1/2-1/4 of external greenhouse cost; 4, land wastage is few, wall The body floor space reduces 66%, and the greenhouse effectively utilizes area to reach 95%, the 40%-55% in more common greenhouse. 5, suitable crop gives birth to Long environment, sufficient growing space is beneficial to expert system, reaches the purpose of increasing both production and income; 6, greenhouse structure is group The dress formula, it is convenient, attractive in appearance solid to install; 7, be suitable for general enclosing extensively, level land, hillside fields, terraced fields all can be built.
