Problems solved by technology

[0006] However, there are few reports on improving the shape of the greenhouse purely from the perspective of changing the frame structure of the greenhouse, and changing the incident angle of the sun from the perspective of the shape and structure design of the greenhouse to achieve the best lighting effect.

Embodiment 1

[0038] Such as figure 1 with figure 2 As shown, the present invention provides an asymmetrical arch-rail solar greenhouse system for fruit trees, which includes a greenhouse. The greenhouse includes a greenhouse body and side walls arranged at both ends of the greenhouse body. The shape of the greenhouse body is asymmetrically arched , the greenhouse body includes 25 greenhouse frames arranged side by side and 10 tie rods arranged at equal intervals, the greenhouse frame includes upper string 1, lower string 2 and connecting rod 3, upper string 1 and lower string 2 are fixedly connected by connecting rod 3, and horizontal tie rod 8 and The lower string 2 is fixedly connected; the outer surface of the greenhouse body is provided with a plastic film and a thermal insulation rear wall 4 .

[0039] Among them, the construction parameters of the greenhouse are as follows: the greenhouse is constructed in an east-west direction, with a length of 100 meters from east to west, a wid...

Embodiment 2

[0046] The present invention provides an asymmetric arch rail solar greenhouse system for fruit trees, the structure of which is as described in Embodiment 1, the difference is that the greenhouse body also includes a first whole-body ventilation opening, a second whole-body ventilation opening and 10 ventilation windows , the first whole-body vent is arranged at the bottom of the daylighting part 7, the second whole-body vent is arranged at the top of the daylighting part 7, and 10 ventilation windows are equally spaced and parallel arranged in the area of ​​the support part 5.

[0047] Wherein, the width of the first whole-body vent is 1 meter, and the height of the bottom edge of the first whole-body vent from the ground is 1-1.5 meters; the width of the second whole-body vent is 1 meter, and the top edge of the second whole-body vent is The vertical height from the shed ridge of the greenhouse body is 0.5-1 meter; the distance between adjacent ventilation windows is 1-1.5 m...

Embodiment 3

[0050] The present invention provides a special asymmetrical arch-rail solar greenhouse system for fruit trees, the structure of which is as described in Embodiment 1, the difference is that the distance between adjacent tie rods 8 is 5 meters, and the side wall at one end is according to the existing There is technology to build a buffer room, which is 3 meters wide and 4 meters long. The buffer room door and the entrance of the greenhouse should be opened in different directions to prevent the cold wind from blowing directly into the greenhouse.

Abstract

The invention relates to an asymmetry arch rail sunlight greenhouse system special for fruit trees and a construction method of the asymmetry arch rail sunlight greenhouse system. The asymmetry arch rail sunlight greenhouse system comprises a greenhouse. The greenhouse comprises a greenhouse body and side walls arranged at the two ends of the greenhouse body. Asymmetry arches are arranged on the outer portion of the greenhouse body. The greenhouse body comprises a plurality of greenhouse frameworks arranged side by side, and transverse pull rods arranged at equal intervals. Each greenhouse framework comprises an upper chord, a lower chord and connection rods, wherein the upper chord and the lower chord are fixedly connected through the connection rods. The transverse pull rods are fixedly connected with the lower chords. A plastic thin film and a heat preservation rear wall are arranged on the outer surface of the greenhouse body. By means of the asymmetry design of the greenhouse body, the sun incidence angle is improved to the maximum degree, more optical energy and heat energy are absorbed, the requirements of crop physiology for illumination and temperature are met, and the asymmetry arch rail sunlight greenhouse system is particularly suitable for out-of-reason production of the fruit trees. The facility input cost is greatly saved, the asymmetry arch rail sunlight greenhouse system is suitable for operation of enterprises and individuals, and the input-output ratio of out-of-season production is increased.

Description

technical field [0001] The invention relates to an asymmetrical arch rail solar greenhouse system for fruit trees and a construction method thereof, belonging to the technical field of agricultural greenhouses. Background technique [0002] At present, the span of the common metal arch greenhouse without columns is within 4-10m. The incident angle of sunlight limits the ability of daylighting, heat absorption and heat storage, especially for fruit trees. Due to the large size of fruit trees, the planting density of facilities is relatively dense. The structure of the shed is too low and the production space is too small, resulting in insufficient light in the shed, especially in winter, the insulation effect is extremely poor, which seriously affects the off-season production of temperature-loving crops, especially fruit trees. [0003] Chinese patent document CN103548620A discloses a light-controlling and temperature-regulating greenhouse. The greenhouse includes a greenhou...
