It consists of gables on both sides, a maintenance rear wall, a supporting frame and covering materials. Solar energy-saving greenhouse is a type of greenhouse widely used in northern my country. It mainly relies on solar radiation to maintain indoor temperature.

The outer film is covered on the outer bracket and fixed with a retaining spring to maintain stability. Combined with the multiple inner films set in the lower partition, the inner film sags due to gravity, which can form a downward force on the frame. The coordinated traction in multiple directions further improves the load-bearing performance of the frame. The setting of the inner film can reduce the adhesion of water vapor inside the greenhouse to the bottom of the outer film, reduce the weight borne by the outer film, avoid deformation or collapse of the top layer due to rain and snow, and improve the stability of the overall structure of the greenhouse.

[0027] 2. The inner film is installed on the frame through the set rollers and pressure strips, and a cavity with a slower flow rate is formed between the inner film and the outer film, which can effectively absorb the heat radiated by the sunlight. After exchanging and mixing with the air below, the temperature inside the greenhouse changes evenly and the heat storage capacity of the wall or soil is increased. Under the adjustment of the rollers and the rotating shaft, the inner film can present different arc shapes as a whole, thereby increasing the light transmittance of the top of the greenhouse, improving the light quality and light intensity in the greenhouse, and improving the heat absorption performance of the greenhouse.

[0039] Embodiment 1:

[0040] Reference Figure 1-Figure 4 A large-span high-performance solar energy-saving greenhouse comprises a rear wall 1, a rear roof 11 is arranged above the rear wall 1, side walls 12 are arranged at both ends of the rear wall 1, a plurality of side doors 13 are opened on the side walls 12, and a base 14 is connected to the two side walls 12 away from the rear wall 1, and further comprises:

[0041] A plurality of vertical windows 2 are used for ventilation of the greenhouse. The plurality of vertical windows 2 are all provided on the rear wall 1, and the plurality of vertical windows 2 are arranged at equal distances. Glass windows are respectively installed on one side of the plurality of vertical windows 2 located inside the greenhouse.

[0042] The electrical device 3 is used to detect and adjust the internal environment of the greenhouse, and the electrical device 3 is installed on the rear wall 1;

[0043] The frame 4 is arranged on the top of the greenhouse, and the two ends of the frame 4 are respectively connected to the rear roof 11 and the base 14, so as to provide support for the greenhouse structure;

[0044] The outer film 5 and the inner film 6 are used to transmit light and reduce heat loss. The outer film 5 and the inner film 6 are both arranged on the frame 4;

[0045] An irrigation mechanism 7, comprising a plurality of delivery pipes 71 and sprinklers 72, for increasing air humidity and providing moisture to crops;

[0046] The heat preservation mechanism 8 is arranged above the rear roof 11 and covers the outer film 5 to reduce heat loss and maintain the internal temperature of the greenhouse.

[0047] In this embodiment, the rear wall 1, the side wall 12 and the base 14 provide support for the basic components of the greenhouse. The rear roof 11 cooperates with the outer film 5 covering the outside to form the ceiling of the greenhouse, thereby forming a closed space as a whole, which has the effect of keeping the crops inside warm and promoting the growth of crops under different conditions. By opening the glass windows at the vertical windows 2 respectively, the air inside the greenhouse can be exchanged with the outside for ventilation, and the hot and humid air can be discharged in time to adjust the indoor temperature and humidity.

[0048] Embodiment 2:

[0049] Different from the first embodiment, Figure 2 and Figure 5 This embodiment also has the following further contents: the rear wall 1 is arranged parallel to the base 14, one end of the outer film 5 is connected to the slot opened on the rear roof 11 through a retaining spring, the other end of the outer film 5 is connected to the top of the base 14, the rear roof 11 cooperates with the outer film 5 to form a closed greenhouse, and a film pressing line 15 for improving the stability of the outer film 5 is arranged on the top of the base 14.

[0050] Specifically, the outer film 5 covers the top of the greenhouse, and sunlight shines into the greenhouse through the outer film 5, storing the radiated heat to achieve the effect of regulating the temperature. Through the provision of multiple retaining springs, the outer film 5 is tightly fitted to the hanging frame 4 to ensure the stability of the outer film 5, and the edge of the outer film 5 is reinforced by the film pressing line 15 to improve the sealing of the outer film 5 after covering, reduce heat loss, avoid gaps that cause external cold air to enter the greenhouse, ensure that the temperature inside the greenhouse is uniform, and provide stable and suitable conditions for crop growth.

[0051] Implementation three:

[0052] Compared with the first embodiment and the second embodiment, referring to Figure 6-8The frame 4 includes an outer frame 41 and an inner frame 42, and both the outer frame 41 and the inner frame 42 are arranged in an arc shape. The outer frame 41 is arranged above the inner frame 42, and a plurality of connecting rods 43 are commonly connected between the outer frame 41 and the inner frame 42. A plurality of middle columns 44 are fixedly connected below the inner frame 42. The plurality of middle columns 44 are vertically arranged, and the bottoms of the plurality of middle columns 44 are respectively provided with column foot stones for support. A connecting rod 45 is arranged between two adjacent frames 4, and the two ends of the connecting rod 45 are respectively fixedly connected to the side walls of the connecting rod 43 corresponding to the position.

[0053] Specifically, the outer bracket 41 and the inner bracket 42 are both of arc-shaped design. When installing the outer film 5, it can ensure that the outer film 5 is at a suitable angle, thereby improving the transmittance of light and improving the lighting performance of the greenhouse. Furthermore, the outer bracket 41 and the inner bracket 42 are connected by multiple connecting rods 43 at different angles, which can decompose the load borne by the outer bracket 41, improve the overall rigidity of the skeleton 4, and cooperate with the support of multiple middle columns 44 to improve the stability of the skeleton 4 when the span is large.

[0054] In addition, a plurality of slots are provided on the side wall of the outer bracket 41, and the outer film 5 is connected to the outer bracket 41 through a correspondingly arranged retaining spring, and a plurality of positioning blocks are provided at the bottom of the inner bracket 42, and limiting slots are respectively provided on the plurality of positioning blocks, and an inner film 6 is commonly connected between the plurality of positioning blocks. It should be noted that the plurality of inner films 6 are partitioned and arranged below the outer film 5, and a plurality of small area chambers are formed between the outer film 5, and the air circulation between the plurality of chambers is slow, so that a plurality of buffer areas are formed after absorbing the solar radiation, and when exchanging and mixing with the air below, the temperature inside the greenhouse is ensured to change evenly.

[0055] Furthermore, one end of the inner film 6 is wound with a roller 61, and both ends of the roller 61 are fixedly connected with a rotating shaft 62. The two rotating shafts 62 are respectively connected to the limiting grooves opened on the positioning block through gaskets, and a pull rope is wound on the rotating shaft 62. The other end of the inner film 6 is provided with a pressure strip 63, and the width of the pressure strip 63 is equal to the width of the upper limit groove of the positioning block at the corresponding position. It should be noted that one end of the inner film 6 is connected to the inner bracket 42 through the pressure strip 63, and the other end is wound on the roller 61. By arranging a gasket on the rotating shaft 62, the friction between the rotating shaft 62 and the positioning block on the inner bracket 42 can be increased. The damping therebetween is used to fix the retracted and extended length of the inner film 6, so that the bottom of the inner film 6 sags to form a parabolic arc surface, thereby increasing the contact area with sunlight, thereby increasing the radiation angle and ensuring that the greenhouse receives better heat.

[0056] In addition, the water vapor inside the greenhouse will adhere to the bottom of the inner film 6, reducing the contact between the droplets and the outer film 5, thereby reducing the load borne by the single-layer film. When encountering rainy and snowy weather, it can avoid damage caused by the influence of snow and water vapor in a certain area. At the same time, the small droplets that escape during irrigation will also gather at the bottom of the inner film 6 and drip onto the crops below again, thereby improving the utilization rate of water resources. Furthermore, when exposed to sunlight, the volume of droplets gathered at the bottom of the inner film 6 can be observed to judge the temperature and internal humidity conditions, which is convenient for the auxiliary electrical equipment 3 to measure and irrigate in time.

[0057] Embodiment 4:

[0058] Reference Figure 7 and Figure 8 Compared with embodiments one to three, multiple delivery pipes 71 are respectively connected to the inner bracket 42 through clamps, and the multiple delivery pipes 71 are equidistantly arranged, and the multiple delivery pipes 71 are connected by hoses, and the hoses are connected to the external pump group. The insulation mechanism includes a roller shutter 81 and an insulation quilt 82, and the roller shutter 81 is arranged between two adjacent insulation quilts 82.

[0059] A control console is provided on the electrical device 3 , and the control console is used to control the start and stop of the external pump group and the roller shutter machine 81 connected to the irrigation mechanism 7 , and the external pump group, the roller shutter machine 81 and the control console are all electrically connected to the electrical device 3 .

[0060] Furthermore, by starting the corresponding electrical equipment 3 through the control console, the water supply of the external pump group can be controlled, and the water source can be delivered to the delivery pipe 71 at the same time, and finally sprayed onto the crops below through the nozzle 72, and the crops are irrigated according to the growth conditions. The roller shutter 81 on the top of the greenhouse is started, and the thermal insulation blanket 82 rolled up on the rolling rod of the roller shutter 81 can be released. Under the traction of the counterweight block at the bottom of the thermal insulation blanket 82, it is fully covered on the outside of the greenhouse, thereby reducing the heat loss on the roof at night, relying on the walls and soil to release the stored heat, and maintaining the temperature inside the greenhouse.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
