Abstract

The utility model relates to a high-efficiency energy-saving sunlight greenhouse which comprises a framework, a plastic film and a wall body, wherein, the plastic film is covered on the framework. The high-efficiency energy-saving sunlight greenhouse is characterized in that the wall body comprises an upper wall body and a lower wall body, a heat insulation plate is clamped in the lower wall body, a heat preservation plate is clamped in the upper wall body, handle walls which horizontally penetrate through the wall body are arranged in a rear wall body, the distance between every two handle walls is from 1 to 1.2m, the height of the greenhouse is from 3.5 to 3.6m and the width is from 8.5 to 9.0m, an elevation angle of a front roofing is from 21 to 23 degrees, and one end of the greenhouse is provided with an operating room. The greenhouse of the utility model has the advantages that firstly, the lighting effect of the greenhouse is good, a better direct lighting condition can be formed in different seasons, and weak light areas are reduced; secondly, the heat preservation effect is good, the special design of the rear wall body can farthest preserve sunlight absorbed in the daytime, and the heat conduction, the heat radiation and the heat abstraction at night can be reduced as much as possible.

Description

Efficient-economical solar-greenhouse

Technical field

The utility model relates to a kind of greenhouse by solar heat, especially relates to a kind of efficient-economical solar-greenhouse that is applicable to latitude about 33 °-35 ° of north latitude.

Background technology

At present, the northern China vast farmers is in autumn and winter season plantation crops, generally adopt the green house technology, because it is economical and practical, and prolonged the plantation time limit, made the growth of crops not be subjected to the restriction in season, increased peasant's income to a certain extent, therefore, green house is rather well received in northern China.Present greenhouse by solar heat mostly by big-canopy framework, fixedly the canopy face and the back wall form, but owing on the INSULATION DESIGN of canopy face angle and body of wall, exist problem, thereby make the effective rate of utilization of green house not high, be mainly reflected in following two aspects: 1. daylighting area is big inadequately, on certain plastic tunnel area coverage, because its angle design is unreasonable, influenced the direct projection area and the direct projection time of sunlight, the daylighting effect is undesirable.2. heat insulation effect is bad, the sunshine that absorb daytime, because it is not good enough that body of wall designs heat-insulating property in the night greenhouse, thereby the sunshine major part that absorbs daytime is lost, and can not utilize fully, make the temperature in the booth at night can not get good adjustment, therefore, the temperature that the crops normal growth needs can not get guaranteeing that this directly has influence on growth and the output thereof of crops.

Designer of the present utility model relies on the practical experience in fields such as being engaged in that all kinds of agricultural equipments are researched and produced for many years, on the basis of feasibility study repeatedly, fully takes into account local geographical position and environment, designs the technical solution of the utility model.

Summary of the invention

The purpose of this utility model is: the deficiency at above-mentioned green house exists, a kind of efficient-economical solar-greenhouse is provided, and it can accept the sunshine on daytime to greatest extent, and has good heat insulation effect night.

The utility model is achieved in that a kind of efficient-economical solar-greenhouse, comprise skeleton, plastic film, body of wall, described plastic film covers on the skeleton, it is characterized in that described body of wall comprises body of wall and following body of wall, clamp warming plate in the described last body of wall, clamped thermal insulation board in the described following body of wall.

In the utility model: be provided with the handle wall that crosses body of wall in the body of wall under described.

In the utility model: the distance between the described handle wall is 1m-1.2m.

In the utility model: described greenhouse height is 3.5m-3.6m, and the greenhouse width is 8.5m-9.0m, and the front roof elevation angle is 21 °-23 °.

In the utility model: an end in described greenhouse is provided with between operation.

Than present green house, the utlity model has following advantage: 1. daylighting is effective, and the utility model fully takes into account local physical condition, makes it can both form direct projection condition preferably in different seasons, reduce low light level district, utilized solar energy to greatest extent; 2. high insulating effect, the body of wall unique design can make the sunshine of absorption on daytime preserve to greatest extent up and down, reduce as much as possible night heat pass to, the scattering and disappearing of thermal radiation and heat, make the temperature in greenhouse at night be not less than 10 °, for the normal growths of crops provides adapt circumstance; 3. heat accumulation is good, because every greenhouse is equipped with between operation, is not only to be used for placing the relevant means of production between operation, and can prevent and treat cold air and enter the greenhouse, and the temperature in greenhouse is played adjusting, cushioning effect.

Fig. 4 is a vertical view of the present utility model.

Among the figure: 1, front roof angle, 2, skeleton, 3, go up body of wall, 4, body of wall down, 5, thermal insulation board, 6, the handle wall, 7, concrete layer, 8, warming plate, 9, cement pre-fabricated panel, 10, between operation, 11, interior powder, 12, brick, 13, outer powder, 14, back roofing angle.

Embodiment

Accompanying drawing is nonrestrictive to disclose concrete structure of the present utility model, below in conjunction with accompanying drawing the utility model is described further:

As seen from Figure 1, front roof angle 1 is 21 °-23 ° in the utility model, the length of whole green house generally is advisable at 50m-60m, skeleton 2 general steel frame construction or the magnalium composites of adopting, being spaced apart about 1m between skeleton and the skeleton, back roofing angle 14 between last body of wall 3 and the following body of wall 4 is 135 °-140 °, the design of this angle has not only increased the direct projection area of daylight on daytime, and reduced the shade that the greenhouse causes, the height in greenhouse is between 3.5m-3.6m, and the width in whole greenhouse is between 8.5m 9m.

As seen from Figure 2, the thickness of body of wall 4 is about 0.6m down in the utility model, and its structure is interior powder 11, brick 12, thermal insulation board 5, brick 12, outer powder 13 successively from inside to outside, and being provided with of thermal insulation board 5 can keep the temperature at night effectively; Be provided with the handle wall 6 that several cross body of wall in the following body of wall 4, the distance between the handle wall 6 is that 1m-1.2m is advisable, the fastness that has strengthened the greenhouse that is provided with of the wall 6 of shaking hands.

By Fig. 3, Fig. 4 as seen, the length of last body of wall 3 is that 1.5m-1.6m is advisable, and its structure is to mix dirt bed 7, warming plate 8, cement steel prefabricated board 9 successively from inside to outside.On certain land area, for the sunlight direct projection effect that guarantees that the greenhouse is best, distance between every greenhouse is not less than 5m, and each greenhouse all disposes between an operation 10, the place of rest not only can be provided for administrative staff between operation, can also place the production equipment that needs, for example roller shutter machine, irrigation installation etc., the more important thing is that the control cold air directly enters the greenhouse, plays the effect of adjusting, buffering to indoor temperature.
