[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] Example 1: Figures 1 to 7 As shown, an intelligent greenhouse according to an embodiment of the present invention includes a greenhouse body 1, a sunshade cloth 13 and a wiping roller 5; A shell 4 is fixedly provided on the top of the greenhouse body 1, and a winding assembly is installed inside the shell 4; One end of the sunshade cloth 13 is connected to the reeling assembly, and the sunshade cloth 13 can be reeled or released by the reeling assembly; The wiping roller 5 is fixed to the end of the sunshade cloth 13 away from the winding assembly; When the reeling assembly releases the sunshade cloth 13, the wiping roller 5 pulls the sunshade cloth 13 out of the housing 4 under the action of its own gravity, so that the sunshade cloth 13 is unfolded and covers the top outer surface of the greenhouse body 1 to achieve sunshade; the wiping roller 5 maintains contact with the top outer surface of the greenhouse body 1, thereby wiping and cleaning the top outer surface; When the reeling assembly reels the sunshade cloth 13, the sunshade cloth 13 is stored inside the housing 4; When in operation, the greenhouse body 1 is composed of an internal support frame and a plastic film, forming a closed structure. Inside the greenhouse, an intelligent control system is configured, including a temperature control system, a humidity control system, a lighting system, an irrigation system, etc. These systems are all existing technologies and will not be described in detail here; through these systems, the environment inside the greenhouse can be precisely controlled to ensure that plants grow under optimal conditions; In addition, it is also equipped with a controller, a light sensor and a limiter. When the external light intensity exceeds a predetermined threshold, the controller receives a signal from the light sensor, starts the winding assembly, and releases the sunshade cloth 13. One end of the sunshade cloth 13 is connected to the winding assembly, and the other end is fixed to the wiping roller 5. The wiping roller 5 falls freely due to its own gravity, pulling the sunshade cloth 13 to unfold; after the sunshade cloth 13 is unfolded, it covers the top outer surface of the greenhouse body 1 to play a sunshade role; when the sunshade cloth 13 is fully unfolded and covers the roof, the limiter triggers a signal to stop the action of the winding assembly to ensure that the sunshade cloth 13 is completely covered; at this time, the sunshade cloth 13 effectively blocks excessive sunlight, reduces direct ultraviolet rays, lowers the temperature in the greenhouse, and maintains a suitable environment to avoid damage to crops caused by high temperature or strong light; During the unfolding of the sunshade cloth 13, the wiping roller 5 always maintains contact with the top outer surface of the greenhouse body 1, thereby wiping and cleaning the roof surface. This design ensures that the light transmittance of the roof will not decrease due to dust accumulation, thereby improving the photosynthetic efficiency of crops in the greenhouse. This process simultaneously achieves sunshade and dust cleaning functions, reducing the need for manual cleaning and equipment investment, and lowering overall operation and maintenance costs. It also reduces the erosion of dust and impurities on the greenhouse structure, effectively extending the service life of the greenhouse. When the external light intensity is moderate, the controller will control the winding component to start again, and roll the sunshade cloth 13 back into the shell 4, restoring the light transmittance of the greenhouse roof, so that energy can be used efficiently; in addition, by storing the sunshade cloth 13 inside the shell 4, it can also effectively protect the sunshade cloth 13 and reduce dust adhesion.

[0021] The winding assembly includes a second rotating shaft 12 symmetrically arranged on both sides of the interior of the shell 4, one end of the sunshade cloth 13 is fixedly connected to the second rotating shaft 12, the other end of the sunshade cloth 13 passes through the through slot 8 opened on the side wall of the shell 4 and is fixedly connected to the wiping roller 5, the second rotating shaft 12 on both sides is respectively fixed with a gear 2 11 at adjacent positions of the inner wall of the end of the shell 4, and a rotating shaft 1 9 is symmetrically arranged at the middle position of the second rotating shaft 12 on both sides, and the rotating shaft 1 9 is rotatably connected to the shell 4, and a motor 7 is fixed on the outer wall of the shell 4, and one of the rotating shafts 1 9 is driven to rotate by the motor 7, and a gear 10 is respectively fixed on the rotating shaft 1 9 on both sides, and the gears 10 on both sides are meshed with each other, and the gears 10 on both sides are respectively meshed with the adjacent gear 2 11; During operation, the controller starts the motor 7 through a signal, and the motor 7 drives one of the rotating shafts 9 to rotate. The gears 10 on both sides engage with each other, so that the gears 10 rotate synchronously in opposite directions. The gear 10 engages with the gear 2 11, driving the gear 2 11 and the rotating shaft 2 12 to rotate synchronously in opposite directions. This mechanism can ensure that the sunshade cloths 13 on both sides are unfolded or reeled in synchronously. The drive of the motor 7 makes the unfolding and reeling actions of the sunshade cloth 13 smooth and synchronous, thereby accurately controlling the position and state of the sunshade cloth 13; in addition, through the drive of the motor 7, the entire reeling process is automated, reducing the need for manual operation and improving work efficiency.

[0022] It also includes a limit assembly, which includes limit frames symmetrically arranged at both ends of the greenhouse body 1, and the limit frames include an arc-shaped mounting frame 3 that is snapped into the top of the greenhouse body 1. The bottom of both sides of the mounting frame 3 is decomposed and fixed with a column 2, and the shell 4 is fixed in the middle of the mounting frames 3 on both sides. A slide rail 6 is provided in the middle of the mounting frame 3, and connecting rods 14 are rotatably installed at both ends of the wiping roller 5. The end of the connecting rod 14 away from the wiping roller 5 passes through the slide rail 6 and a limit block 18 is fixed on the end, and the limit block 18 is in contact with the outer wall of the mounting frame 3; During operation, the bottom end of the column 2 is buried in the soil, and the outer sides of the two ends of the greenhouse body 1 are supported and limited by the limit frame, thereby enhancing the stability of the greenhouse and preventing it from tilting or shaking under the action of wind or other external forces; the connecting rod 14 cooperates with the slide rail 6 so that the two ends of the wiping roller 5 can be stably positioned, and the limit block 18 is in close contact with the outer wall of the mounting frame 3. Through cooperation with the slide rail 6, it is ensured that the wiping roller 5 always maintains a relatively vertical state with the mounting frame 3 to avoid deflection; in addition, through the design of the limit frame and the limit block 18, the wiping roller 5 can accurately control its position when winding or releasing the sunshade cloth 13, so that the sunshade cloth 13 is more uniform and stable during the winding and releasing process, effectively avoiding bending or wrinkling of the sunshade cloth 13, thereby improving the accuracy of the winding process.

[0023] A cleaning cover 19 is detachably mounted on the outer wall of the wiping roller 5. During operation, the cleaning cover 19 is made of materials such as polyester fiber and microfiber, and is detachably mounted on the wiping roller 5 using Velcro or a snap ring. The cleaning cover 19 is used to wipe dust off the surface of the greenhouse without damaging the surface of the greenhouse.

[0024] The bottom ends of both sides of the mounting frame 3 extend vertically downward, and a gap is provided between the bottom ends of both sides of the mounting frame 3 and the outer wall of the greenhouse body 1; during operation, when the wiping roller 5 moves to the bottom of the track, the wiping roller 5 is separated from the surface of the greenhouse body 1, which is convenient for subsequent cleaning of dust on the wiping roller 5.

[0025] A cleaning assembly is provided at the lower portion of the opposite sides of the mounting brackets 3 on both sides, and the dust on the surface of the cleaning sleeve 19 is cleaned by the cleaning assembly. The cleaning assembly includes a mounting block 15, and the mounting block 15 is provided in a pair and symmetrically fixed on both sides of the slide rail 6. An elastic rope 16 is fixed between the corresponding mounting blocks 15 on the mounting brackets 3 on both sides. The elastic ropes 16 are provided in pairs, and the elastic ropes 16 on both sides are respectively in contact with the side walls of the cleaning sleeve 19; During operation, when the sunshade cloth 13 is released, the wiping roller 5 moves downward along the track until the cleaning cover 19 contacts the elastic ropes 16 on both sides. The cleaning cover 19 and the elastic ropes 16 can both be deformed. Under the action of the wiping roller 5's own weight, the wiping roller 5 and the cleaning cover 19 can squeeze through the elastic ropes 16 on both sides, so that the elastic ropes 16 can scrape the side walls of the cleaning cover 19, which can effectively and automatically clean the dust on the surface of the cleaning cover 19, reduce the workload of manual cleaning, and improve the self-cleaning ability of the equipment. In addition, when the movement of the wiping roller 5 and the cleaning sleeve 19 is obstructed, the descending speed slows down. At this time, the winding assembly continues to release the sunshade cloth 13. Under the action of the gravity of the released sunshade cloth 13, the sunshade cloth 13 can continue to be released outward, so that part of the sunshade cloth 13 will accumulate above the wiping roller 5. When the wiping roller 5 completely passes through the elastic rope 16, the descending speed suddenly increases to tighten the sunshade cloth 13, and then the dust attached to the sunshade cloth 13 can be shaken off, thereby realizing automatic cleaning of the sunshade cloth 13.

[0026] The elastic ropes 16 are provided in multiple pairs in the vertical direction. During operation, the multiple pairs of elastic ropes 16 are provided so as to realize multiple cleaning of the cleaning sleeve 19 and achieve a better dust cleaning effect.

[0027] A spring 17 is fixed inside the mounting frame 3 and on the side wall at the end of the slide rail 6. When working, the spring 17 is arranged below the elastic rope 16. When the wiping roller 5 and the cleaning cover 19 pass through the lowest elastic rope 16, they can accelerate and impact the top of the spring 17. Through the rebound effect of the spring 17, the wiping roller 5 and the cleaning cover 19 can be shaken up and down, so as to further shake off the dust attached to the surface of the cleaning cover 19 and improve the cleaning effect.

[0028] Example 2: Figure 8As shown, compared with Example 1, another embodiment of the present invention is: a cover plate 22 is detachably installed on the side adjacent to the mounting frame 3 on the limit block 18, the connecting rod 14 is fixed to the center of the cover plate 22, and a mounting groove 20 is provided inside the limit block 18, and a ball 21 is rotatably installed in the mounting groove 20, and a plurality of balls 21 are provided and are evenly distributed in a circular ring shape on the side wall of the limit block 18, and the side of the ball 21 passes through the through hole provided on the cover plate 22 and contacts with the side wall of the mounting frame 3; when working, the disassembly and maintenance of the ball 21 are facilitated by setting a detachable change; by setting a roller, the friction between the limit block 18 and the mounting frame 3 is reduced, so that the wiping roller 5 can descend more smoothly.

[0029] Working principle: When the external light intensity exceeds a predetermined threshold, the controller receives a signal from the light sensor, starts the reeling assembly, and releases the sunshade cloth 13. One end of the sunshade cloth 13 is connected to the reeling assembly, and the other end is fixed to the wiping roller 5. The wiping roller 5 falls freely under its own gravity, pulling the sunshade cloth 13 to unfold; after the sunshade cloth 13 is unfolded, it covers the top outer surface of the greenhouse body 1 to play a sunshade role; when the sunshade cloth 13 is fully unfolded and covers the roof, the limiter triggers a signal to stop the action of the reeling assembly to ensure that the sunshade cloth 13 is completely covered; at this time, the sunshade cloth 13 effectively blocks excessive sunlight, reduces direct ultraviolet rays, lowers the temperature in the greenhouse, and maintains a suitable environment to avoid high temperature or strong light from affecting the work In the process of unfolding the sunshade cloth 13, the wiping roller 5 always keeps in contact with the top outer surface of the greenhouse body 1, thereby wiping and cleaning the roof surface; this design can ensure that the light transmittance of the roof will not decrease due to dust accumulation, thereby improving the photosynthetic efficiency of crops in the greenhouse; this process simultaneously completes the sunshade and dust cleaning functions, reduces the need for manual cleaning and equipment investment, and reduces the overall operation and maintenance costs; in addition, it reduces the erosion of dust and impurities on the greenhouse structure, effectively extending the service life of the greenhouse; when the external light intensity is moderate, the controller will control the reeling component to start again, rewind the sunshade cloth 13 back into the shell 4, restore the light transmittance of the greenhouse roof, and make energy use more efficient; During the process of releasing the sunshade cloth 13, the wiping roller 5 moves downward along the track until the cleaning cover 19 contacts the elastic ropes 16 on both sides. The cleaning cover 19 and the elastic ropes 16 can both be deformed. Under the action of the wiping roller 5's own gravity, the wiping roller 5 and the cleaning cover 19 can squeeze through the middle of the elastic ropes 16 on both sides, so that the elastic ropes 16 can scrape the side walls of the cleaning cover 19, which can effectively and automatically clean the dust on the surface of the cleaning cover 19, reduce the workload of manual cleaning, and improve the self-cleaning ability of the equipment. When the movement of the wiping roller 5 and the cleaning sleeve 19 is blocked, the descending speed slows down. At this time, the winding assembly continues to release the sunshade cloth 13. Under the action of the gravity of the released sunshade cloth 13, the sunshade cloth 13 can continue to be released outward, so that part of the sunshade cloth 13 will accumulate above the wiping roller 5. When the wiping roller 5 completely passes the elastic rope 16, the descending speed suddenly increases to tighten the sunshade cloth 13, thereby shaking off the dust attached to the sunshade cloth 13, and realizing automatic cleaning of the sunshade cloth 13. When the wiping roller 5 and the cleaning sleeve 19 pass through the lowest elastic rope 16, they can be accelerated to impact the top of the spring 17. Through the rebound effect of the spring 17, the wiping roller 5 and the cleaning sleeve 19 can be shaken up and down, so as to further shake off the dust attached to the surface of the cleaning sleeve 19 and improve the cleaning effect.
