[0035] Working principle:

[0036] Firstly, the rain shelter frame (the rain shelter frame is used for grape planting) needs to be built when it is used, the mounting rods on the shed frame 35 are built one by one, then installed with the ground, the polyvinyl chloride film 37 is installed on the upper end of the shed frame 35, the two sides of the front and rear end (the installation method and material are prior art), then the user installs two groups of supporting mechanisms on the front and rear ends of the shed frame 35, the two groups of supporting mechanisms are fixedly installed with the ground through the supporting columns 13 at the lower end, while the two groups of supporting mechanisms are installed, the two groups of first photovoltaic modules 21 and the second photovoltaic modules 25 are installed on the two inclined surfaces of the polyvinyl chloride film 37, specifically, the two first photovoltaic modules 21 are located in the middle, the two second photovoltaic modules 25 are located on the two sides, and the wind deflector 11 is installed between the supporting columns 13 of the two groups of supporting mechanisms.

[0037] Second, after installation, the rain shelter frame can be used, and the rain shelter frame can change mode according to sunny and rainy days, and can also change mode according to whether there is sunlight every day. When there is sunlight during the day, the user can control two servo motors 31 to work, the two servo motors 31 drive the second screw 32 to rotate through the output shaft, and the thread of the second screw 32 is left-handed thread. At this time, the second screw 32 and the lifting block 17 are connected through the thread, the second screw 32 drives the lifting block 17 to move down, and the lifting block 17 drives the two connecting rods 16 to move down, the two connecting rods 16 drive the first rack 15 to move down, the first rack 15 is connected with the first flat gear 12 through the thread, and the first rack 15 drives the first flat gear 12 to rotate through the meshing between the two first racks 15 and the first flat gear 12. At this time, the first flat gear 12 drives the wind shield 11 to rotate, and the two wind shields 11 are turned to be perpendicular to the two sides of the shed frame 35, so that the two sides of the shed frame 35 are communicated with the internal space, and the rain shelter frame is ventilated with the outside. The wind shield 11 provided by the present application can be turned over, the ventilation of the rain shelter frame is realized, the temperature and humidity in the shed are adjusted, the microclimate conditions suitable for grape growth are created, the occurrence of diseases and pests is reduced, the freshness of the air in the shed is improved, the aerobic respiration and photosynthesis of the grape are promoted, and the growth and development of the grape are beneficial.

[0038] The third step, while the second screw 32 rotates, the second bevel gear 33 is driven to rotate, at this time, through the meshing between the second bevel gear 33 and the two first bevel gears 28 (the second bevel gear 33 and the two first bevel gears 28 are special umbrella gears, and the intersection angle is one hundred and twenty degrees, in some special mechanical transmission systems in the prior art, the intersection angle of sixty degrees, one hundred and twenty degrees, etc. will appear), the two first bevel gears 28 will rotate at the same time, at this time, the rotation direction of the second bevel gear 33 is clockwise (from top to bottom), so the rotation direction of the two first bevel gears 28 is counterclockwise (from the two first bevel gears 28 between the two sides), and when the thread of the first screw 27 is right-handed thread, and the first screw 27 rotates counterclockwise, the first screw 27 drives the third rack 24 and the second rack 22 to move to the two sides of the shed frame 35, at this time, through the meshing of the third rack 24 and the third spur gear 26, and the meshing of the second rack 22 and the second spur gear 23, the first photovoltaic module 21 and the second photovoltaic module 25 can be turned to be perpendicular to the inclined surface of the polyvinyl chloride film 37, so that most of the area of the polyvinyl chloride film 37 is exposed, so that sunlight can be irradiated into the rain shelter frame, the first photovoltaic module 21 and the second photovoltaic module 25 can be rotated, so that the first photovoltaic module 21 and the second photovoltaic module 25 can protect the polyvinyl chloride film 37, when turned to be perpendicular to the inclined surface of the polyvinyl chloride film 37, the polyvinyl chloride film 37 is exposed to the maximum, sufficient sunlight is ensured to be irradiated into the shed, the light requirement of grape growth is met, the photosynthesis efficiency of grape is improved, and the development and quality of fruit are promoted.

[0039] Fourth, when encountering rainy and snowy weather or night without sunlight, the user can control the reverse rotation of the servo motor 31, and the second screw rod 32 drives the lifting block 17 to move upwards, thereby driving the two first racks 15 to move upwards, at this time, the two first spur gears 12 are reversed, and the two windshields 11 are parallel to the two sides of the shed frame 35, thereby shielding the position of the rain shelter frame from the outside air, preventing rain and snow from entering the rain shelter frame, and preventing some wild animals from entering the greenhouse at night. When it snows, the user can remove the snow by opening the two first photovoltaic components 21 and the second photovoltaic component 25. Since the third rack 24 inside the V-shaped support rod 36 will first contact the third spur gear 26, driving the third spur gear 26 to rotate, when the third rack 24 moves halfway on the circumference of the third spur gear 26, the first photovoltaic component 21 will first tilt, at this time, the snow on the first photovoltaic component 21 will slide onto the second photovoltaic component 25, at this time, the second rack 22 will drive the second spur gear 23 to rotate, and the gear ratio between the second rack 22 and the second spur gear 23 is smaller than the gear ratio between the third rack 24 and the third spur gear 26, so the second spur gear 23 rotates faster than the third spur gear 26. When the second photovoltaic component 25 rotates to be perpendicular to the inclined surface of the polyvinyl chloride film 37, the first photovoltaic component 21 is also perpendicular to the inclined surface of the polyvinyl chloride film 37, at this time, the snow on the second photovoltaic component 25 can completely slide off the two sides of the rain shelter frame. The first photovoltaic component 21 and the second photovoltaic component 25 and the windshields 11 are arranged to effectively prevent rain and snow from entering the shed when it rains and snows or at night, avoid the influence of freezing and water accumulation on the grapes, maintain the stability of the environment in the shed, and avoid the impact of raindrops or snowflakes directly on the polyvinyl chloride film 37 of the rain shelter, causing damage to the polyvinyl chloride film 37. After the first photovoltaic component 21 and the second photovoltaic component 25 are closed, they act as a "protective cover", reducing the physical impact of precipitation on the polyvinyl chloride film 37. The second rack 22, the second spur gear 23, the third rack 24, and the third spur gear 26 with different gear ratios are arranged to make the rotation angles of the first photovoltaic component 21 and the second photovoltaic component 25 inconsistent after snowfall, thereby removing the snow on the first photovoltaic component 21 and the second photovoltaic component 25, preventing damage to the first photovoltaic component 21, the second photovoltaic component 25, and the polyvinyl chloride film 37 caused by snow accumulation, and ensuring the normal operation and service life of the photovoltaic components.

[0040] In the fifth step, the two first photovoltaic components 21 and the second photovoltaic component 25 on the rain shelter frame are in the open state, and the end faces thereof are all oriented towards the sky, at this time, the sunlight can be collected through the internal structure, and then converted into electric energy for use of various devices required for grape planting in the rain shelter frame, the first photovoltaic component 21 and the second photovoltaic component 25 are arranged, solar energy can be efficiently collected and converted into electric energy, electric power support is provided for the devices required for grape planting in the rain shelter frame (such as an irrigation system, lighting equipment and the like), green self-sufficiency of energy is realized, dependence on external power grids is reduced, energy cost is saved, carbon emission is reduced, and the requirement of sustainable development is met.
