DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 9 As shown, the present invention is a film greenhouse combining agricultural planting and photovoltaic power generation, comprising a greenhouse body 1, a toothed rod 6 is arranged at the upper end of the greenhouse body 1, a butt joint sleeve 10 is sleeved and connected to the surface of the toothed rod 6, and a support seat 21 is fixedly installed on both sides of the toothed rod 6 at the upper end of the greenhouse body 1;

[0030] A bracket 22 is symmetrically fixedly installed on the top surface of the support seat 21 near the two short sides, a first cylinder 23 is rotatably connected to the inside of the bracket 22 near one side, a rotating joint is rotatably connected to the upper end of the first cylinder 23 inside the bracket 22, the output end of the first cylinder 23 is rotatably connected to the rotating joint, a hook 24 is fixedly connected to the surface of the rotating joint, a sleeve seat 25 is fixedly installed at the middle of the top surface of the support seat 21, a second cylinder 26 is rotatably connected to the surface of the sleeve seat 25, and a frame plate 27 is rotatably connected to the surface of the second cylinder 26;

[0031] A top frame 2 is welded and fixed to the top surface of the shed body 1, and connecting plates 3 are welded and fixed to the two short sides of the top frame 2. A support plate is welded and fixed to one end surface of the connecting plate 3 at the upper and lower ends, and a first motor 5 is fixedly connected to the bottom surface of the support plate. A screw rod 4 is fixedly connected to the output end of the first motor 5. When controlling the docking sleeve 10 to move up and down to perform a designated cleaning operation, the user can control the two sets of first motors 5 to operate simultaneously, and the screw rod 4 on the output end will cooperate with the wire groove 9 to move the toothed rod 6 up and down;

[0032] The toothed rod 6 has protruding nodes 7 welded and fixed on both end surfaces, and the protruding nodes 7 have thread grooves 9 on their surfaces. The toothed rod 6 has protruding blocks 8 welded and fixed on its side surfaces, and the threaded rod 4 is spirally connected to the thread grooves 9.

[0033] The inner surface of the docking sleeve 10 is provided with a card groove 11, and the card groove 11 is embedded and connected with the protrusion 8. A connecting sleeve 12 is fixedly connected to one end surface of the docking sleeve 10, and an anti-dropping sleeve 13 is symmetrically fixedly connected to the inner surface of the connecting sleeve 12. The surface of the anti-dropping sleeve 13 is embedded and connected with a rotating sleeve 14. The interior of the rotating sleeve 14 is provided with a docking groove 15, and the outer surface of the rotating sleeve 14 is fixedly connected with a telescopic joint 16;

[0034] A motor 17 is embedded and installed inside the sleeve 12, and a gear 18 is fixedly installed on the output end of the motor 17. A ring gear 19 is rotatably connected inside the sleeve 12, and the gear 18 is meshed with the ring gear 19. A protruding pin 20 is fixedly connected to the surface of the ring gear 19, and the protruding pin 20 is embedded and connected with the docking groove 15. After cleaning a certain position on the surface of the photovoltaic panel or film, the user can control the two sets of motors 17 to operate in sequence. During this process, when the corresponding motor 17 is operating, the gear 18 on its output end will start to rotate and rotate inside the sleeve 12 in conjunction with the ring gear 19 meshed with it. The convex needle 20 on its surface will reciprocate through the anti-drop sleeve 13, thereby linking the embedded rotating sleeve 14 from the exposed position, and cooperating with the docking groove 15 on its surface, so that the telescopic section 16 will rotate. Whenever the telescopic section 16 abuts against the surface of the toothed rod 6, the docking sleeve 10 connected to the corresponding connecting sleeve 12 will complete the positioning. At this time, another set of motors 17 can make corresponding actions to make the telescopic section 16 away from the surface of the toothed rod 6, and complete the pushing work by friction. The overall structure is similar to the movement of earthworms, which is not only stable and orderly, but also the vibration generated during the movement can further drive the impurities and debris to fall off;

[0035] One end surface of the sleeve 12 is located on one side of the anti-slip sleeve 13 and is symmetrically fixedly connected with a folding frame 121. The surface of the folding frame 121 is located in the middle and is fixedly connected with a positioning frame 122. The surface of the positioning frame 122 is rotatably connected with a brush roller 123. During the coordinated movement of the sleeve 12, the folding frame 121 will perform a reciprocating motion of bending and stretching, thereby driving the brush roller 123 to continuously extend and retract, so as to ensure that the surface of the photovoltaic panel can be cleaned as much as possible. In some areas, the surface of the agricultural greenhouse film is prone to water accumulation, especially in the rainy season or when there is high humidity in the greenhouse. Through continuous reciprocating motion, it can help to drain the accumulated water on the surface of the film or guide the water to a specific drainage channel, thereby reducing the retention of water and avoiding deformation or damage of the film caused by water pressure. Due to the temperature difference between the inside and outside of the greenhouse, water droplets often form on the surface of the film, especially in the early morning or at night. These water droplets not only affect the light transmittance, but also may cause long-term damage to the film material. The roller device may help evaporate or discharge some water droplets when reciprocating, thereby reducing condensation on the film surface, improving light transmittance and the service life of the film. The reciprocating motion helps to keep the film taut and prevent the film from loosening due to long-term use, thereby affecting the temperature control and ventilation effect inside the greenhouse. Appropriate pressure and adjustment can help maintain the tension of the film and extend its service life.

[0036] The bottom surface of the frame plate 27 is located at the two short sides and is fixedly connected with a rotating sleeve 28, and the rotating sleeve 28 is fixedly connected to the output end of the second cylinder 26. The bottom surface of the frame plate 27 is located on both sides of the rotating sleeve 28 and is welded and fixed with hook legs 29, and the hook claws 24 are embedded and connected with the hook legs 29. The inside of the frame plate 27 is embedded and connected with a photovoltaic panel 30, and the inside of the photovoltaic panel 30 is located at the two long sides and fixedly installed with a second motor 31, and the output end of the second motor 31 is fixedly connected to the frame plate 27. When controlling the photovoltaic panel 30 to rotate at a corresponding angle, the corresponding first cylinder 23 must first be controlled to operate. After the output end is extended, it will cooperate with the hook claw 24 to rotate around the rotating joint until the hook claw 24 is buckled on the surface of the hook leg 29, and then the second cylinder 26 is controlled to extend and retract, so that the entire frame plate 27 can be controlled to rotate around the hook claw 24 connected to the hook leg 29. When it is necessary to control the photovoltaic panel 30 to rotate in another direction, the user can control the second motor 31 to rotate so that it can further rotate on the surface of the frame plate 27.

[0037] The working principle of the present invention is as follows: when controlling the up and down movement of the docking sleeve 10 accessory to perform a designated cleaning operation, the user can control the two first motors 5 to operate simultaneously, and the screw rod 4 on the output end thereof will cooperate with the screw groove 9 to move the toothed rod 6 up and down. After cleaning a certain position on the surface of the photovoltaic panel or the film, the user can control the two motors 17 to operate successively. During this process, when the corresponding motor 17 is operating, the gear 18 on its output end will start to rotate, and cooperate with the gear ring 19 meshing with it to rotate inside the sleeve 12, and the convex pin 20 on its surface will reciprocate through the anti-drop sleeve 13, thereby linking the embedded rotating sleeve 14 from the exposed position, and cooperating with the docking groove 15 on its surface, the telescopic joint 16 will rotate. Whenever the telescopic joint 16 abuts against the surface of the toothed rod 6, the docking sleeve 10 connected to the corresponding sleeve 12 will complete the positioning, and at this time the other motor 1 7 can make corresponding actions, so that the telescopic joint 16 is away from the surface of the toothed rod 6, and the pushing work is completed by friction. The overall structure is similar to the movement of earthworms, which is not only stable and orderly, but also the vibration generated during the movement can further drive the impurities and debris to fall. During the movement of the sleeve 12, the folding frame 121 will bend and stretch reciprocating motion, thereby driving the brush roller 123 to continuously extend and retract to ensure that the surface of the photovoltaic panel can be cleaned as much as possible. In some areas, the surface of the agricultural greenhouse film is prone to water accumulation, especially in the rainy season or when there is high humidity in the greenhouse. Through continuous reciprocating motion, it can help to drain the accumulated water on the surface of the film or guide the water to a specific drainage channel, thereby reducing the retention of water and avoiding deformation or damage of the film caused by water pressure. Due to the temperature difference between the inside and outside of the greenhouse, water droplets often form on the surface of the film, especially in the early morning or at night. These water droplets not only affect the light transmittance, but also may cause long-term damage to the film material. The roller device may help evaporate or discharge some water droplets when reciprocating, thereby reducing condensation on the film surface, improving light transmittance and the service life of the film, and the reciprocating motion helps to keep the film taut and prevent the film from loosening due to long-term use, thereby affecting the temperature control and ventilation effect inside the greenhouse. Through appropriate pressing and adjustment, it can help maintain the tension of the film and extend its service life. When controlling the photovoltaic panel 30 to rotate at a corresponding angle, the corresponding first cylinder 23 must first be controlled to operate. After the output end is extended, it will cooperate with the hook 24 to rotate around the rotating joint until the hook 24 is engaged with the surface of the hook leg 29, and then the second cylinder 26 is controlled to extend and retract, so that the entire frame plate 27 can be controlled to rotate around the hook 24 connected to the hook leg 29. When the photovoltaic panel 30 needs to be controlled to rotate in another direction, the user can control the second motor 31 to rotate so that it can further rotate on the surface of the frame plate 27.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
