A novel and unique two-way single-slope solar greenhouse.

Description

Two-way single-slope solar greenhouse

technical field

The invention relates to a solar greenhouse, more specifically to a bidirectional single-slope solar greenhouse, which is suitable for the early or delayed production of various fruits, vegetables and crops produced every year.

Background technique

The eyesight greenhouse uses sunlight as the main source of energy. It can produce crops efficiently and without pollution in the cold winter without heating, or in extremely cold conditions with a small amount of heating. With the popularization and development of solar greenhouses in rural areas, urban residents in northern my country can still eat fresh and delicious vegetables and fruits even in the cold winter, which not only brings huge economic benefits to farmers, but also enriches urban residents in winter. In daily life, solar greenhouses have become the main body of northern facility agriculture. However, this kind of solar greenhouse is usually a one-way and one-slope structure, and the construction cost is high. At the same time, in order to ensure the lighting requirements of the solar greenhouse, a certain distance must be ensured between the sheds, resulting in low land utilization. There are also large-scale multi-span solar greenhouse structures, which have good lighting effects and high area utilization, but their construction is expensive. The two-way single-slope solar greenhouse of the present invention not only has low construction cost, but also has high utilization rate of arable land area, and can meet the growth requirements of different crops at the same time.

Contents of the invention

The purpose of the present invention is to provide a two-way single-slope solar greenhouse, which utilizes a rear wall to set up two greenhouses, the north and the south, which has good thermal insulation performance and high utilization rate of cultivated land, which can greatly reduce the construction cost of the greenhouse and is suitable for different crops , Growth requirements in different seasons.

The object of the present invention is achieved in that it comprises a retaining wall with a rear wall and a gable wall, a skeleton, and a shed film, and is characterized in that the skeletons of the north-south shed are symmetrically supported on the top of the rear wall, and the other ends of the skeleton support respectively On the ridge wall set on the front and rear sides of the back wall, the shed film buckles are placed on the framework of the north and south sheds to form two symmetrical or basically symmetrical greenhouses in the north and south.

The advantage of the present invention is that since the two greenhouses in the north and south share one back wall, the investment and arable land for building the greenhouse can be greatly reduced, and at the same time, the force on the back wall is more reasonable, and the area utilization rate of the arable land in the traditional single-slope solar greenhouse can be increased by about 40%; And because there are no cold gables on both sides of the back wall, the heat of the greenhouse cannot be lost through the back wall, and the north shed plays a role in insulating the back wall, which can effectively increase the indoor temperature of the south shed; and the two north-south greenhouses facing the sun and backlight Therefore, the early and delayed production of fruit trees and vegetables can be carried out in the two greenhouses, especially the delayed production of fruit trees; compared with the single-slope solar greenhouse in the two-way single-slope solar greenhouse, the temperature of the southern shed in winter can Increase the temperature by 3-5°C, improve the growing environment of crops, increase crop yields, and reduce heating costs; after increasing the area of the north shed, the area is doubled, and the cost is increased by about 25%. It is a novel and unique two-way single-slope solar greenhouse with significant economic benefits, low cost and high income.

Description of drawings

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the specific structure schematic diagram of the present invention.

Detailed ways

In Fig. 1, the two-way single-slope solar greenhouse has an enclosure wall consisting of a rear wall 8 and gable walls 10 on both sides of the rear wall 8 . It also has skeletons 3, 9 and shed film. The back wall 8 is a composite thermal insulation wall, and a 120mm or 90mm thick benzene board insulation layer 7 is sandwiched in the middle of the rear wall 8, and both sides of the wall insulation layer 7 are 240mm thick brick wall layers 6, forming a composite Insulated walls. The back wall 8 is an intermediate wall shared by the two solar greenhouses in the north and the south. While the back wall 8 serves as a load-bearing wall, it also has better thermal insulation and heat storage performance. On the front and rear sides of the rear wall 8, there is a ridge wall 2, 11 respectively, and a cold-proof ditch is arranged outside the ridge wall 2, 11, and a benzene board insulation layer with a thickness of 50-80mm and a height of 800-1000mm is built in the cold-proof ditch 1, 12, used to prevent the loss of surface heat in the greenhouse. Two ends between the rear wall 8 and the ridge walls 2 and 11 are surrounded by gable walls 10 . Skeleton 3,9 adopts steel plane truss structure, and the ends of skeleton 3,9 front and back slopes all weld the skeleton seat that useful angle steel is made. The skeletons 3 and 9 of the north and south sheds are the same plane trusses. The rear slope ends of the north-south shed framework 3,9 are symmetrically fixed on the top of the rear wall 8 through the framework seat. The front slope ends of the north-south shed framework 3,9 are symmetrically fixed on the ridge walls 2,11 on the front and rear sides of the back wall 8 through the skeleton seat at the front slope end. The north-south shed skeletons 3,9 are symmetrically fixed on the tops of the back wall 8 and the ridge walls 3,9. The shed film is respectively covered on the north and south shed frameworks 3 and 9 on both sides of the rear wall 8, forming two symmetrical or substantially symmetrical greenhouses in the north and south. Then pave 20mm thick wooden boards on the back slopes 4 of the north and south shed skeletons 3 and 9, add 120mm thick benzene board insulation layer, and finally add 1:5 lime slag to make slopes with an average thickness of 80mm + 40mm thick C20 fine stone concrete inner diameter The two-way steel wire mesh waterproof surface layer 5 with a distance of Φ3 and a spacing of 150 mm. The outer covering materials of the front slopes of skeletons 3 and 9 are straw curtains or straw curtains plus paper quilts, and two curtains can be added inside. This greenhouse is an innovation of the single-slope solar greenhouse. On the basis of the original single-slope solar greenhouse, the north shed is added to form a two-way single-slope solar greenhouse with south and north sheds. The south shed can produce various fruits and vegetables throughout the year; the north shed is suitable for early or delayed production of fruits and vegetables. Compared with the single-slope solar greenhouse, the temperature of the south shed can be increased by 3-5°C in winter, which can improve the growth environment of crops, increase crop yield, and reduce heating costs at the same time; increase the area of the north shed to the original two times, the cost increases by about 25%, and the early and delayed production of vegetables and fruit trees has significant economic benefits.
