[0004] Regarding the above-mentioned issues, the following technical defects have been found: the solar photovoltaic film on greenhouses in the existing technology is inconvenient to install and unfold, which reduces the overall practicality of the greenhouse. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the solar photovoltaic film on greenhouses in the prior art is inconvenient to install and unfold, which reduces the overall practicality of the greenhouse.

[0006] To address the aforementioned technical problems, embodiments of this application provide a flexible photovoltaic module solar-tunable greenhouse, comprising:

[0007] The inner arch rod has an arched cross-section.

[0008] The outer arch member has an arched cross-section and is fitted over the inner arch member; and

[0009] Photovoltaic regulating installation components are located on the outer arch rod;

[0010] The photovoltaic regulating installation component includes a photovoltaic film, a first arc plate, and a second arc plate. The photovoltaic film is located on the side of the first arc plate and the second arc plate that are close to each other. A lead screw is rotatably inserted through the side of the first arc plate. The arc surface of the lead screw is threadedly connected to the second arc plate. The cross sections of the first arc plate and the second arc plate are both arc-shaped.

[0011] In some embodiments, a welding plate is fixedly connected to the outer arch rod, and a servo motor is fixedly connected to one side of the short arm end of the welding plate. The output end of the servo motor is fixedly connected to one end of the lead screw.

[0012] In some embodiments, a plurality of guide rods are threaded through the side of the second arc plate, and one end of the guide rods is fixedly connected to one side of the first arc plate.

[0013] In some embodiments, the photovoltaic regulating installation assembly further includes several hanging rings, which are divided into two groups. The two groups of hanging rings are fixedly connected to the sides of the first and second arc plates that are close to each other. Several hooks are fixedly connected to both sides of the photovoltaic film, and the hooks abut against the inner wall of the hanging rings.

[0014] In some embodiments, a number of arc-shaped frames are fixedly connected to the side of the photovoltaic film away from the outer arch rod, and the arc-shaped frames are evenly distributed on one side of the photovoltaic film.

[0015] In some embodiments, the photovoltaic film comprises, in sequence from the side furthest from the outer arch to the side closest to the outer arch, an outer film layer, a solar film layer, and a PDLC adjustable light film layer.

[0016] In some embodiments, a circular block is fixedly connected to one end of the lead screw, and a toothed hole is opened on the side of the circular block away from the lead screw. An electric actuator is fixedly connected to the side of the first arc plate away from the second arc plate. A connecting plate is fixedly connected to the output end of the electric actuator, and a toothed block is fixedly connected to one side of the connecting plate. The size of the toothed block is adapted to the toothed hole.

[0017] The above technical solution allows for easy assembly and disassembly of the photovoltaic film by setting up photovoltaic adjustment and installation components. Furthermore, the photovoltaic film can be easily unfolded after installation, thereby improving the overall practicality of the greenhouse.

[0018] In addition, the outermost film layer uses an oleophobic, stain-resistant, and wear-resistant coating. While allowing light transmission, it also has a self-cleaning function, reducing manual cleaning costs and mitigating the problem of low solar energy conversion efficiency caused by dirt, thus improving solar power generation efficiency. Because of the oleophobic, stain-resistant, and wear-resistant coating, most dirt can be cleaned by everyday wind and rain. The solar film layer is a flexible, light-transmitting solar film layer, unlike the opaque and rigid properties of traditional solar panels. The flexible material has high plasticity and a large bending angle, allowing it to be bent into various shapes to meet the various appearance requirements of greenhouses. The PDLC adjustable light film layer can control the amount of light required for plants inside the greenhouse. Light is provided when needed, and reflected when not needed. Solar energy can be stored to provide electricity for lighting, ventilation, and irrigation facilities within the greenhouse. It can also be used for zoned light transmission, allowing light to pass through areas that need it at different times and reflect light to store energy in areas that don't. This expands the types of plants that can be grown inside the greenhouse, controls the duration and intensity of light exposure, and provides other functions. Attached Figure Description

[0035] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a flexible photovoltaic module solar adjustable greenhouse, comprising:

[0036] Inner arch rod 2, the cross-section of inner arch rod 2 is arch-shaped;

[0037] Outer arch member 1, with an arched cross-section, is fitted over the inner arch member 2; and

[0038] Photovoltaic regulating installation component 3 is located on the outer arch rod 1.

[0039] The following section will explain the specific setup and function of photovoltaic regulation installation component 3.

[0040] Reference Figures 3 to 6 As shown in this embodiment, the photovoltaic adjustment installation component 3 includes a photovoltaic film 301, a first arc plate 302, and a second arc plate 303. The photovoltaic film 301 is disposed on the side of the first arc plate 302 and the second arc plate 303 that are close to each other. A lead screw 304 is rotatably inserted through the side of the first arc plate 302. The arc surface of the lead screw 304 is threadedly connected to the second arc plate 303. The cross-sections of the first arc plate 302 and the second arc plate 303 are both arc-shaped. By setting the photovoltaic adjustment installation component 3, the photovoltaic film 301 can be easily disassembled and assembled, and the photovoltaic film 301 can be easily unfolded after installation, thereby improving the overall practicality of the greenhouse.

[0041] A welding plate 305 is fixedly connected to the outer arch rod 1. A servo motor 306 is fixedly connected to one side of the short arm end of the welding plate 305. The output end of the servo motor 306 is fixedly connected to one end of the lead screw 304. Starting the servo motor 306 can control the lead screw 304 to rotate automatically, which improves the convenience of the photovoltaic film 301 unfolding process.

[0042] Several guide rods 307 are threaded through the side of the second arc plate 303. One end of the guide rod 307 is fixedly connected to one side of the first arc plate 302. When the lead screw 304 drives the second arc plate 303 to move, the guide rod 307 can guide and position the second arc plate 303, thereby improving the stability of the second arc plate 303 during movement.

[0043] The photovoltaic regulating installation component 3 also includes several hanging rings 308. The hanging rings 308 are divided into two groups. The two groups of hanging rings 308 are fixedly connected to the side of the first arc plate 302 and the second arc plate 303 that are close to each other. Several hooks 309 are fixedly connected to both sides of the photovoltaic film 301. The hooks 309 abut against the inner wall of the hanging rings 308. By setting the hooks 309 and hanging rings 308, the photovoltaic film 301 can be easily installed and removed, making the installation and removal of the photovoltaic film 301 simpler and more efficient.

[0044] A number of arc-shaped frames 315 are fixedly connected to the side of the photovoltaic film 301 away from the outer arch rod 1. The arc-shaped frames 315 are evenly distributed on one side of the photovoltaic film 301. The arc-shaped frames 315 can provide better support for the photovoltaic film 301, enhance the stability of the film, and prevent the film from being deformed or damaged by external factors such as wind and rain.

[0045] The photovoltaic film 301 comprises, sequentially from the side furthest from the outer arch 1 to the side closest to the outer arch 1, an outer film layer, a solar film layer, and a PDLC adjustable light film layer. The outermost film layer uses an oleophobic, stain-resistant, and wear-resistant coating, which, while allowing light transmission, also has a self-cleaning function, reducing manual cleaning costs and mitigating the problem of low solar energy conversion efficiency caused by dirt, thus improving solar power generation efficiency. Because of the oleophobic, stain-resistant, and wear-resistant coating, most dirt can be cleaned away by everyday wind and rain. The solar film layer is a flexible, light-transmitting solar film layer, unlike the opaque and rigid properties of traditional solar panels. The flexible material has high plasticity and a large bending angle, allowing it to be bent into various shapes to meet the diverse appearance requirements of greenhouses. The PDLC adjustable light film layer can control the amount of light required for plants in the greenhouse. It can provide light when needed and reflect light when not needed. Solar energy can be stored to provide electricity for lighting, ventilation, irrigation and other facilities in the greenhouse. It can also control light transmission in different areas at different times. Areas that need light can be transmitted to light, while areas that do not need light can reflect light and store energy. It can expand the types of plants that can be grown in the greenhouse, control the duration of light exposure for plants, control the light intensity and other functions.

[0046] One end of the lead screw 304 is fixedly connected to a circular block 310. A toothed hole 311 is opened on the side of the circular block 310 away from the lead screw 304. An electric push rod 312 is fixedly connected to the side of the first arc plate 302 away from the second arc plate 303. A connecting plate 313 is fixedly connected to the output end of the electric push rod 312. A toothed block 314 is fixedly connected to one side of the connecting plate 313. The size of the toothed block 314 matches that of the toothed hole 311. After the lead screw 304 drives the second arc plate 303 to move to a suitable position, the operator can start the electric push rod 312 to drive the toothed block 314 to insert into the toothed hole 311, thereby limiting the lead screw 304 and improving the stability of the photovoltaic film 301 after it is unfolded.

[0047] When the photovoltaic film 301 needs to be installed on the outer arch 1 of the greenhouse, first hang the hooks 309 on both sides of the photovoltaic film 301 on the inner wall of the hanging ring 308 on the side of the first arc plate 302 and the second arc plate 303 that are close to each other. After the hooks 309 are hung inside the hanging ring 308, start the servo motor 306 to drive the lead screw 304 to rotate. The lead screw 304 drives the second arc plate 303, causing the second arc plate 303 to move one side of the photovoltaic film 301 away from the first arc plate 302. When the photovoltaic film 301 is fully unfolded, stop the operation of the servo motor 306. The adjustment and installation of the photovoltaic film 301 can then be completed. By setting the hooks 309 and the hanging rings 308, the photovoltaic film 301 can be easily installed and removed. The installation and disassembly of the 301 solar film are now simpler and more efficient. When the lead screw 304 drives the second arc plate 303 to move, the guide rod 307 guides and positions the second arc plate 303, thus improving the stability of its movement. The frame provides better support for the photovoltaic film 301, enhancing its stability and preventing deformation or damage caused by wind, rain, or other external factors. Furthermore, the outermost film layer uses an oleophobic, stain-resistant, and wear-resistant coating, which, while allowing light transmission, also has a self-cleaning function, reducing manual cleaning costs and mitigating the problem of low solar energy conversion efficiency caused by dirt, thereby improving solar power generation efficiency. Because of the oleophobic, stain-resistant, and wear-resistant coating, most dirt can be cleaned away by everyday wind and rain. The solar film layer is a flexible, translucent solar film layer, unlike the opaque and rigid properties of traditional solar panels. The flexible material has high plasticity and a large bending angle, allowing it to be bent into various shapes to meet the diverse appearance requirements of greenhouses. The PDLC adjustable light film layer can control the amount of light required for plants in the greenhouse. It can provide light when needed and reflect light when not needed. Solar energy can be stored to provide electricity for lighting, ventilation, irrigation and other facilities in the greenhouse. It can also control light transmission in different areas at different times. Areas that need light can be transmitted and areas that do not need light can reflect and store energy. It can expand the types of plants that can be grown in the greenhouse, control the duration of light exposure for plants, control the light intensity and other functions. Finally, after the lead screw 304 drives the second arc plate 303 to move to the appropriate position, the operator can activate the electric push rod 312 to drive the tooth block 314 to insert into the tooth hole 311, thereby limiting the lead screw 304 and improving the stability of the photovoltaic film 301 after it is deployed.
