Abstract

The utility model relates to a high efficient double layer film arched shed lighting greenhouse, which belongs to greenhouses, and consists of a front wall, a rear wall and a plurality of arched racks, wherein the rear wall is higher than the front wall, each arched rack is of a bow shape, two ends of each arched rack are lapped on the front wall and the rear wall, so that the plurality of arched racks are longitudinally arranged with equal distance, a shed film is covered along the top surface of the bow, and a drip-free shed film is paved along the bottom surface of each bowstring; and the front wall and the rear wall of the greenhouse are parallelly arranged in the west-east direction, the middle of the greenhouse is the symmetrical break point, and wall bodies at two sides of the break point respectively form an included angle of 8 degrees to 15 degrees together with a longitude line. The high efficient double layer film arched shed lighting greenhouse has reasonable structure design, breaks through the method that the traditional shed definitely need heating with straw or coal in winter to improve the temperature of the greenhouse, and has good heat insulation property and good lighting property, the indoor temperature can achieve the requirement of the growth of the crops only through the lighting of the shed film, so that the greenhouse is low in investment, guarantees the sanitation of the interior of the greenhouse, is more beneficial to the growth of crops, and can be widely used in crop cultivation and aquaculture.

Description

The efficient daylighting greenhouse of duplicature shed

Technical field

The utility model belongs to the greenhouse, particularly relates to a kind of plant husbandry or the aquaculture efficient daylighting greenhouse of duplicature shed.

Background technology

At present, the occupancy volume of chamber planting in agricultural planting is increasing, and particularly the winter planting vegetables had both solved vegetables and supplied with problem, can give peasant's extra earning again.But existing greenhouse all needs it is heated in the winter time, to guarantee the needs of vegetable growth.The deficiency of its existence is: heating temperature is low, consume fuel is many, and temperature fluctuation is big, cigarette, grey seriously polluted to the greenhouse; Adopt steam or hot water space heating boiler to heat to the greenhouse in addition by radiator, but its cost height, equipment complexity, cost height.In addition, raising along with people's living standard, the plant of different scales has also developed industry rapidly, promptly enriched the people's carnivorous structure, increased the foreign exchange income again, but present plant mostly is a brick mix structure, on body of wall, have window and come daylighting and ventilation, but it can only be keeped out wind and rain, and do not have the resisting cold effect, particularly waits severe cold season in the winter time, owing to the livestock shed temperature low, be not suitable for raising the cub of firm birth, cause that young baby's survival rate is low, epidemic prevention disease is difficult and become to hold problems such as growth cycle is long; Moreover brick mix structure has also improved the construction cost of whole livestock shed.

Summary of the invention

The utility model is intended to overcome the deficiencies in the prior art, provides a kind of duplicature shed efficient daylighting greenhouse, promptly is applicable to temperature plant husbandry, also is suitable for the greenhouse cultivation industry.

The efficient daylighting greenhouse of duplicature shed of the present utility model, be to constitute by front wall, back wall and bow member, back wall is higher than front wall, bow member is arc, its two ends are taken on front wall and back wall, some bow members like this are by uniformly-spaced vertically arranging, prolong covering canopy film on the bow end face, prolong by the bottom surface of bowstring and lay non-drop greenhouse film; The front wall in this greenhouse and back wall are the East and West direction that is parallel to each other, and its mid point is the symmetrical break of canopy chamber, and the both sides body of wall of this break all becomes 8 °～15 ° angles with warp.

As further improvement of the utility model, be equipped with geosyncline at front wall and the wall outside, back root, in geosyncline, filled fluffy adiabatic material.

As further improvement of the utility model, described front wall and back wall constitute this position, plane, greenhouse seat Northern Dynasties south and prolong the curved structure of warp.

The efficient daylighting greenhouse of duplicature shed of the present utility model, reasonable in design has been broken the plantation in winter of traditional booth and must have been heated to improve the method for room temperature with straw or fire coal.It is extremely efficient in preserving heat, and daylighting is good, and the daylighting of canopy film own just can make indoor temperature reach the needs of crop production, not only invests lowly, but also has guaranteed the cleaning in the greenhouse, more utilizes the production of crop, and this greenhouse can be widely used in plant husbandry and aquaculture.

Description of drawings

Fig. 1 is the structural representation of the efficient daylighting greenhouse of the utility model duplicature shed;

Fig. 2, Fig. 3 are the vertical view of two kinds of configurations of the utility model.

Embodiment

The efficient daylighting greenhouse of duplicature shed of the present utility model is to be made of front wall 1, back wall 2 and bow member 3, and as shown in Figure 1, back wall 2 is higher than front wall 1; Bow member 3 is arc, and its two ends are taken on front wall 1 and back wall 2, some bow members 3 like this are by uniformly-spaced vertically arranging, prolong on the bow end face to cover the canopy film, and in order to prevent windburn, will be with the solid film of film-pressing line on the film.Prolong by the bottom surface of bowstring and lay non-drop greenhouse film, thickness is generally 0.12～0.16 millimeter.Adopt the double-arc insulation can cover straw screen or mat insulation, time and labour saving.The front wall 1 in this greenhouse and back wall 2 are the East and West direction that is parallel to each other, and its mid point is the symmetrical break of canopy chamber, and the both sides body of wall of this break all becomes 8 °～15 ° angles with warp, as Fig. 2, shown in Figure 3.

Be equipped with geosyncline 4 at front wall 1 and back wall 2 outside roots, filled fluffy adiabatic material in geosyncline 4, because fluffy adiabatic material has more hole, gassy can reduce internal heat and outwards derive.

Described front wall 1 and back wall 2 constitute this position, plane, greenhouse seat Northern Dynasties south and prolong the curved structure of warp, as shown in Figure 2.

The effect of body of wall has two, and the one, load-bearing, the 2nd, heat storing and heat preserving.Load-bearing is exactly to bear the gravity of bow member and its suffered various external force, as blast, crushing by snow and operating personnel's gravity, therefore, requires body of wall that enough intensity is arranged, to guarantee the safety of greenhouse structure.The accumulation of heat effect of body of wall is meant and obtains solar radiant heat daytime, a part of radiant heat held be loaded in body of wall, and diffuse in the greenhouse night again, and it is outdoor that heat is delivered to, and keeps higher room temperature.
