Description

Technical Field

[0001] The present invention belongs to the technical field of rain-sheltering pergolas, and more specifically, particularly relates to a rain-sheltering pergola for grape cultivation. Background Art

[0002] Grapes are woody vines. Grapes have relatively high requirements for moisture. Strictly controlling the moisture in the soil is a prerequisite for growing good grapes. Grapes require more water during the initial growth stage or vegetative growth stage, and in the later growth stage or fruiting stage. When cultivating grapes, a rain-sheltering pergola is needed. Currently, for the rain-sheltering pergolas used in grape cultivation, at least the following technical problems are found: First, during rainy, snowy, and night times, raindrops or snowflakes directly impact the plastic film of the rain-sheltering pergola. Especially during heavy rain or heavy snow weather, the impact force generated by the falling of a large amount of precipitation may damage the plastic film, such as punching small holes or wearing the surface of the film.

[0003] Second, during continuous snowfall, snow accumulates on the plastic film of the rain-sheltering pergola. When too much snow accumulates on the plastic film of the rain-sheltering pergola, the weight of the snow pile will cause a large downward pressure, thereby damaging the plastic film of the rain-sheltering pergola.

[0004] Third, the existing rain-sheltering pergolas lack an effective mechanism for adjusting sunlight irradiation, and cannot flexibly switch between protecting the polyvinyl chloride film and ensuring sufficient sunlight irradiation, which affects the photosynthesis efficiency of grapes and the development quality of fruits.

Detailed implementation manners

[0017] The following further describes the implementation manners of the present invention in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0018] Please refer to Figures 1-11, the present invention provides a rain shelter for grape cultivation, which includes a shed body frame 35, a polyvinyl chloride film 37 is provided on the shed body frame 35, support mechanisms are provided at both the front and rear ends of the shed body frame 35, the support mechanism includes a V-shaped support rod 36, support columns 13 are fixedly installed at both ends of the V-shaped support rod 36, two sets of rotating mechanisms are provided inside the V-shaped support rod 36, and two sets of flipping mechanisms are provided inside the support columns 13. Wind shields 11 are provided at both side ends of the shed body frame 35. Two sets of first photovoltaic modules 21 and second photovoltaic modules 25 are provided on the polyvinyl chloride film 37. Second spur gears 23 are fixedly installed at both side ends of the first photovoltaic module 21, and third spur gears 26 are fixedly installed at both side ends of the second photovoltaic module 25. The transmission mechanism includes a third rack 24, a second rack 22 is provided on the third rack 24, the second rack 22 is meshed and installed with the second spur gear 23, the third rack 24 is meshed and installed with the third spur gear 26, a first screw rod 27 is installed through the third rack 24 and the second rack 22 by threads, and a first bevel gear 28 is fixedly installed on the first screw rod 27. The flipping mechanism includes a connecting rod 16, a first rack 15 is fixedly installed on the connecting rod 16, a second bevel gear 33 is meshed between the first bevel gears 28 in the two sets of transmission mechanisms, a second screw rod 32 is fixedly installed at the lower end of the second bevel gear 33, a lifting block 17 is provided on the second screw rod 32, and the lifting block 17 is fixedly connected to the connecting rods 16 in the two sets of flipping mechanisms. When this rain shelter (the rain shelter is used for grape cultivation) is in use, it needs to be erected first. First, the mounting rods on the shed body frame 35 are erected one by one, then installed on the ground, and then the polyvinyl chloride film 37 is installed at the upper end, both sides, front and rear ends of the shed body frame 35 (the installation method and materials are all prior arts). Then the user installs the two sets of support mechanisms at the front and rear ends of the shed body frame 35 respectively, and the two sets of support mechanisms are fixedly installed on the ground through the support columns 13 at their lower ends. While the two sets of support mechanisms are being installed, the two sets of first photovoltaic modules 21 and second photovoltaic modules 25 will be installed on the two inclined surfaces of the polyvinyl chloride film 37 respectively. Specifically, the two first photovoltaic modules 21 are located in the middle, and the two second photovoltaic modules 25 are located on both sides. And the wind shields 11 are installed between the support columns 13 of the two sets of support mechanisms.

[0019] A first pinion gear 12 meshes with a first rack 15. The first pinion gear 12 is fixedly connected to a wind shield 11. A second rack 22 and a third rack 24 are fixedly installed via an extension plate. The gear ratio between the third rack 24 and a third pinion gear 26 is greater than the gear ratio between the second rack 22 and a second pinion gear 23. After installation is completed, the rain shelter frame can be used. When the rain shelter frame is in use, the mode can be changed according to sunny days, rainy days, and snowy days, or it can also be changed every day according to whether there is sunlight. When there is sunlight during the day, the user can control two servo motors 31 to operate. The two servo motors 31 drive a second screw rod 32 to rotate through output shafts. The thread of the second screw rod 32 is a left-handed thread. At this time, through the threaded connection between the second screw rod 32 and a lifting block 17, the second screw rod 32 drives the lifting block 17 to move downward, and the lifting block 17 drives two connecting rods 16 to move downward. The two connecting rods 16 drive the first rack 15 to move downward. Through the meshing between the two first racks 15 and the first pinion gear 12, the downward movement of the first rack 15 drives the first pinion gear 12 to rotate. At this time, the first pinion gear 12 drives the wind shield 11 to rotate, and the two wind shields 11 will flip to be perpendicular to both sides of the shed body frame 35. At this time, both ends of the shed body frame 35 communicate with its internal space, facilitating ventilation between the rain shelter frame and the outside. By providing the wind shield 11 that can be flipped, the present invention realizes ventilation of the rain shelter frame, helps to adjust the temperature and humidity inside the shed, creates a microclimate condition suitable for grape growth, reduces the occurrence of pests and diseases, improves the freshness of the air inside the shed, promotes the aerobic respiration and photosynthesis of grapes, and is beneficial to the growth and development of grapes.

[0020] The second rack 22, the second spur gear 23, the third spur gear 26, and the first screw rod 27 are all arranged inside the V-shaped support rod 36. A chute 14 is provided inside the support column 13. The first rack 15 and the first spur gear 12 are both arranged in the chute 14 provided in the support column 13. The second bevel gear 33 and the two first bevel gears 28 are special umbrella-shaped gears, and the meshing angle between the second bevel gear 33 and the two first bevel gears 28 is 120 degrees. When the second screw rod 32 rotates, it drives the second bevel gear 33 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 both specially manufactured umbrella-shaped gears, and their included angle is 120 degrees. In some special mechanical transmission systems in the prior art, included angles such as 60 degrees and 120 degrees will occur), the two first bevel gears 28 will rotate simultaneously. At this time, the rotation direction of the second bevel gear 33 is clockwise (viewed from top to bottom), so the rotation directions of the two first bevel gears 28 are counterclockwise (viewed from both sides between the two first bevel gears 28). When the thread of the first screw rod 27 is a right-handed thread and the first screw rod 27 rotates counterclockwise, the first screw rod 27 will drive the third rack 24 and the second rack 22 to move towards both sides of the shed frame 35. At this time, through the meshing between the third rack 24 and the third spur gear 26, and the meshing between the second rack 22 and the second spur gear 23, the first photovoltaic module 21 and the second photovoltaic module 25 can be flipped 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 can be exposed, facilitating sunlight to shine into the rain shelter frame. By providing the rotatable first photovoltaic module 21 and second photovoltaic module 25, the present invention enables the first photovoltaic module 21 and the second photovoltaic module 25 to not only protect the polyvinyl chloride film 37, but also, when flipped to be perpendicular to the inclined surface of the polyvinyl chloride film 37, maximally expose the polyvinyl chloride film 37, ensuring sufficient sunlight shines into the shed, meeting the light requirements for grape growth, improving the photosynthesis efficiency of grapes, and promoting the development and quality improvement of fruits.

[0021] The lifting block 17 is installed through threads on the circumferential surface of the second screw rod 32. A servo motor 31 is provided at the lower end of the second screw rod 32, and the output shaft of the servo motor 31 is fixedly connected to the second screw rod 32. A support plate 34 is fixedly installed on the shed body frame 35, and the servo motor 31 is fixedly installed on the support plate 34. When encountering rainy, snowy weather or when sunlight is not needed at night, the user can control the reverse rotation of the servo motor 31, and the second screw rod 32 will drive the lifting block 17 to move upward, thereby driving the two first racks 15 to move upward. At this time, the two first spur gears 12 reverse rotate, and the two windshields 11 are parallel to the two side ends of the shed body frame 35, so as to block the positions where the rain shelter frame ventilates with the outside world, preventing rain and snow from flying into the rain shelter frame in rainy and snowy weather, and preventing some wild animals from entering the greenhouse at night. When it is snowing, when snow accumulates on the two first photovoltaic modules 21 and the second photovoltaic module 25, the user can turn on the two first photovoltaic modules 21 and the second photovoltaic module 25 to remove the snow. Since the third rack 24 inside the V-shaped support rod 36 will come into contact with the third spur gear 26 first and drive the third spur gear 26 to rotate. When the third rack 24 moves half of the circumference of the third spur gear 26, the first photovoltaic module 21 will tilt first. At this time, the snow on the first photovoltaic module 21 will slide onto the second photovoltaic module 25. At this time, the second rack 22 contacts the second spur gear 23, and 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 less 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 module 25 rotates to be perpendicular to the inclined surface of the polyvinyl chloride film 37, the first photovoltaic module 21 is also perpendicular to the inclined surface of the polyvinyl chloride film 37. At this time, the snow on the second photovoltaic module 25 can completely slide off from both sides of the rain shelter frame. Through the first photovoltaic module 21, the second photovoltaic module 25 and the windshields 11 provided in the present invention, in rainy, snowy weather or at night, it effectively prevents rain and snow from entering the shed, avoids the grape from suffering from freezing damage and waterlogging, keeps the environment in the shed stable, and at the same time can avoid the impact force generated by raindrops or snowflakes directly hitting the polyvinyl chloride film 37 of the rain shelter, causing damage to the polyvinyl chloride film 37. After the first photovoltaic module 21 and the second photovoltaic module 25 are closed, they are like a "protective cover", reducing the physical impact of precipitation on the polyvinyl chloride film 37. Through the second rack 22, the second spur gear 23, the third rack 24 and the third spur gear 26 with different gear ratios provided in the present invention, after snowing, the rotation angles of the first photovoltaic module 21 and the second photovoltaic module 25 are inconsistent, so as to remove the snow on the first photovoltaic module 21 and the second photovoltaic module 25, preventing the snow accumulation from damaging the first photovoltaic module 21, the second photovoltaic module 25 and the polyvinyl chloride film 37.It ensures the normal operation and service life of the photovoltaic modules. When the two first photovoltaic modules 21 and the second photovoltaic modules 25 on the rain shelter frame are in the open state, their end faces face the sky. At this time, through the internal structure, sunlight can be collected and then converted into electric energy for use by various equipment required for grape cultivation in the rain shelter frame. By setting the first photovoltaic modules 21 and the second photovoltaic modules 25, the present invention can efficiently collect solar energy and convert it into electric energy, providing power support for the equipment (such as irrigation systems, lighting equipment, etc.) required for grape cultivation in the rain shelter frame, realizing green self-sufficiency of energy, reducing dependence on the external power grid, saving energy costs, and at the same time reducing carbon emissions, meeting the requirements of sustainable development.

[0022] Working principle: First step, when the rain shelter frame (used for grape cultivation) is in use, it needs to be erected first. First, the mounting rods on the shed body frame 35 are erected one by one and then installed on the ground. Then, polyvinyl chloride films 37 are installed at the upper end, both front and rear ends on both sides of the shed body frame 35 (the installation method and materials are all prior arts). Then, the user installs two sets of support mechanisms at the front and rear ends of the shed body frame 35 respectively. The two sets of support mechanisms are fixedly installed on the ground through the support columns 13 at their lower ends. While the two sets of support mechanisms are being installed, the two first photovoltaic modules 21 and the second photovoltaic modules 25 are respectively installed on the two inclined surfaces of the polyvinyl chloride film 37. Specifically, the two first photovoltaic modules 21 are in the middle and the two second photovoltaic modules 25 are on both sides, and a wind baffle 11 is installed between the support columns 13 of the two sets of support mechanisms.

[0023] Step 2: After installation is completed, the rain shelter can be used. When in use, the rain shelter can change its mode according to sunny days, rainy days, and snowy days, or it can also change its mode every day according to whether there is sunlight. 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 rod 32 to rotate through the output shafts. The thread of the second screw rod 32 is a left-handed thread. At this time, through the threaded connection between the second screw rod 32 and the lifting block 17, the second screw rod 32 will drive the lifting block 17 to move downward, and the lifting block 17 will drive two connecting rods 16 to move downward. The two connecting rods 16 drive the first rack 15 to move downward. Through the meshing between the two first racks 15 and the first spur gear 12, the downward movement of the first rack 15 will drive the first spur gear 12 to rotate. At this time, the first spur gear 12 will drive the windshields 11 to rotate, and the two windshields 11 will flip to be perpendicular to both sides of the shed body frame 35. At this time, both ends of the shed body frame 35 are communicated with its internal space, facilitating ventilation between the rain shelter and the outside. By providing the windshields 11 that can be flipped, the present invention realizes the ventilation of the rain shelter, helps to adjust the temperature and humidity inside the shed, creates a microclimate suitable for grape growth, reduces the occurrence of pests and diseases, improves the freshness of the air inside the shed, promotes the aerobic respiration and photosynthesis of grapes, and is beneficial to the growth and development of grapes.

[0024] Step 3: When the second screw 32 rotates, it drives the second bevel gear 33 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 both specially manufactured bevel gears with an included angle of 120 degrees. In some special mechanical transmission systems in the prior art, included angles such as 60 degrees and 120 degrees will occur), the two first bevel gears 28 will rotate simultaneously. At this time, the rotation direction of the second bevel gear 33 is clockwise (when looking from top to bottom), so the rotation directions of the two first bevel gears 28 are counterclockwise (when looking from between the two first bevel gears 28 to both sides). When the thread of the first screw 27 is a right-handed thread and the first screw 27 rotates counterclockwise, the first screw 27 will drive the third rack 24 and the second rack 22 to move towards both sides of the shed frame 35. At this time, through the meshing between the third rack 24 and the third spur gear 26, and the meshing between the second rack 22 and the second spur gear 23, the first photovoltaic module 21 and the second photovoltaic module 25 can be flipped 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 can be exposed, facilitating sunlight to shine into the rain shelter. By providing the rotatable first photovoltaic module 21 and second photovoltaic module 25, the present invention enables the first photovoltaic module 21 and the second photovoltaic module 25 to protect the polyvinyl chloride film 37 and, when flipped to be perpendicular to the inclined surface of the polyvinyl chloride film 37, maximally expose the polyvinyl chloride film 37, ensuring sufficient sunlight shines into the shed, meeting the light requirements for grape growth, improving the photosynthesis efficiency of grapes, and promoting the development and quality improvement of fruits.

[0025] Step 4: When encountering rainy, snowy weather or when sunlight is not required at night, the user can control the reverse rotation of the servo motor 31. Then, the second screw rod 32 will drive the lifting block 17 to move upward, which can drive the two first rack bars 15 to move upward. At this time, the two first spur gears 12 will reverse, and the two windshields 11 will be parallel to the two side ends of the shed frame 35, thereby blocking the ventilation position between the rain shelter frame and the outside. This can prevent rain and snow from flying into the rain shelter frame during rainy and snowy weather and prevent some wild animals from entering the greenhouse at night. When it is snowing and snow accumulates on the two first photovoltaic modules 21 and the second photovoltaic module 25, the user can turn on the two first photovoltaic modules 21 and the second photovoltaic module 25 to remove the snow. Since the third rack bar 24 inside the V-shaped support rod 36 will first come into contact with the third spur gear 26 and drive the third spur gear 26 to rotate. When the third rack bar 24 moves halfway on the circumferential surface of the third spur gear 26, the first photovoltaic module 21 will tilt first. At this time, the snow on the first photovoltaic module 21 will slide onto the second photovoltaic module 25. At this time, the second rack bar 22 comes into contact with the second spur gear 23. Then, the second rack bar 22 will drive the second spur gear 23 to rotate, and the gear ratio between the second rack bar 22 and the second spur gear 23 is smaller than the gear ratio between the third rack bar 24 and the third spur gear 26. Therefore, the second spur gear 23 will rotate faster than the third spur gear 26. When the second photovoltaic module 25 rotates to be perpendicular to the inclined surface of the polyvinyl chloride film 37, the first photovoltaic module 21 is also perpendicular to the inclined surface of the polyvinyl chloride film 37. At this time, the snow on the second photovoltaic module 25 can completely slide off from both sides of the rain shelter frame. By setting the first photovoltaic module 21, the second photovoltaic module 25 and the windshield 11, the present invention effectively prevents rain and snow from entering the shed during rainy, snowy weather or at night, avoids the grape from suffering from freezing damage and waterlogging, maintains the stability of the shed environment, and at the same time can avoid the impact force generated by raindrops or snowflakes directly impacting on the polyvinyl chloride film 37 of the rain shelter, which may damage the polyvinyl chloride film 37. After the first photovoltaic module 21 and the second photovoltaic module 25 are closed, they are like a "protective cover", reducing the physical impact of precipitation on the polyvinyl chloride film 37. By setting the second rack bar 22, the second spur gear 23, the third rack bar 24 and the third spur gear 26 with different gear ratios, after snowing, the rotation angles of the first photovoltaic module 21 and the second photovoltaic module 25 are inconsistent, so that the snow on the first photovoltaic module 21 and the second photovoltaic module 25 can be removed, preventing the snow accumulation from damaging the first photovoltaic module 21, the second photovoltaic module 25 and the polyvinyl chloride film 37, and ensuring the normal operation and service life of the photovoltaic modules.

[0026] In the fifth step, when the two first photovoltaic modules 21 and the second photovoltaic module 25 on the rain shelter frame are in the open state, their end faces are all facing the sky. At this time, through the internal structure, sunlight can be collected and then converted into electrical energy for use by various devices required for grape cultivation in the rain shelter frame. By providing the first photovoltaic module 21 and the second photovoltaic module 25, the present invention can efficiently collect solar energy and convert it into electrical energy, providing power support for the devices required for grape cultivation in the rain shelter frame (such as irrigation systems, lighting devices, etc.), achieving green self-sufficiency of energy, reducing dependence on the external power grid, saving energy costs, and at the same time reducing carbon emissions, meeting the requirements of sustainable development.
