[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1
[0022] Please see Figures 1 to 2 This utility model provides a technical solution: an automatic temperature adjustment and light optimization device for greenhouses, including a greenhouse body 1, with a roof 2 integrally formed at the top of the greenhouse body 1. A system control device 6 is fixedly connected to the inner cavity of the greenhouse body 1. The system control device 6 is a controller and is connected to a temperature sensor 4 and a light intensity sensor 5. The temperature sensor 4 and the light intensity sensor 5 are fixedly connected to the inner cavity of the greenhouse body 1. Support platforms 10 are fixedly connected to both sides of the surface of the roof 2. Two winding rollers 11 are rotatably connected to the surface of the support platforms 10. Scrapers 1 are overlapped on the surface of the winding rollers 11. The surface of the take-up roller 11 is wrapped with a sunshade cloth 7, and the other end of the sunshade cloth 7 is fixedly connected to the auxiliary rod 9. The auxiliary rod 9 is slidably connected to the surface of the canopy 2. The auxiliary rod 9 and the elastic band 21 are set to make the tension of the sunshade cloth 7 uniform during the winding process, avoiding the phenomenon of twisting and knotting of the sunshade cloth 7. Furthermore, the scraper 19 and the cleaning brush 15 are overlapped on the surface of the take-up roller 11, which can not only clamp and guide the sunshade cloth 7 during the winding process, but also achieve the smoothing and cleaning of the surface of the sunshade cloth 7, thereby improving the use effect of the sunshade cloth 7 and the working efficiency of the winding device.
[0023] Example 2
[0024] Please see Figure 3Based on Embodiment 1, in order to keep the sunshade cloth 7 flat when it is rolled up and down, a motor device 3 is fixedly connected to the inner cavity at the bottom of the canopy 2, and two sets of fixing rods 8 are fixedly connected to the two inclined surfaces at the top of the canopy 2. Each set of fixing rods 8 has two rods, and the two fixing rods 8 are distributed in parallel. The fixing rods 8 have a square plate-like structure. The surface of the fixing rods 8 is provided with a sliding groove 13, which is a "T" shaped groove. A sliding rod 14 is slidably connected to the surface of the sliding groove 13. The sliding rod 14 has a "T" shaped block structure. A secondary rod 9 is fixedly connected between the two sliding rods 14. An elastic band 21 is fixedly connected to one end of the surface of the sliding rod 14, and the other end of the elastic band 21 is fixedly connected to the surface of the sliding groove 13.
[0025] The auxiliary rod 9 is used to fix one end of the sunshade cloth 7, so that the tension force on the sunshade cloth 7 is consistent throughout the winding and unwinding process, thus preventing the sunshade cloth 7 from knotting and tangling during winding and unwinding. An elastic band 21 is provided. When the sunshade cloth 7 is wound up, the elastic band 21 is in a stretched state. When the sunshade cloth 7 is unwound, the elastic band 21 rebounds, causing the auxiliary rod 9 to move downwards as a whole, thus preventing insufficient power during the unwinding process of the sunshade cloth 7, which could lead to the sunshade cloth 7 shifting or twisting.
[0026] Example 3
[0027] Please see Figures 4 to 5 Based on Embodiment 2, in order to achieve leveling and cleaning of the surface of the sunshade cloth 7, the support platform 10 is a square plate structure. The surface of the support platform 10 is fixedly connected to a bearing, and the take-up roller 11 is rotatably connected to the bearing. The surface of the support platform 10 is provided with a plate groove 20, which is a square groove. Two limiting posts 16 are fixedly connected to the surface of the plate groove 20. The limiting posts 16 are circular plates with a "T"-shaped cross section, and the diameter of the circular plate at the top of the limiting post 16 is larger than that at the bottom. A spring 17 is sleeved on the surface of the limiting post 16. One end of the spring 17 is fixedly connected to the bottom surface of the plate groove 20, and the other end of the spring 17 is fixedly connected to the surface of the horizontal plate 12. The spring 17 is in a compressed state. The horizontal plate 12 is a square plate structure. Limiting holes 18 are opened on both sides of the surface of the horizontal plate 12. The limiting posts 16 are inserted into the limiting holes 18. The cleaning brush 15 and the scraper 19 are fixedly connected to one end surface of the horizontal plate 12, and the cleaning brush 15 and the scraper 19 are distributed in parallel.
[0028] A spring 17 is provided and is in a compressed state. When the sunshade cloth 7 is being rolled up and down, the diameter of the take-up roller 11 changes continuously. The take-up roller 11 squeezes the scraper 19 and the cleaning brush 15. The spring 17 is forced upward and dynamically rebounds, so that the surfaces of the cleaning brush 15 and the scraper 19 are always in contact with the surface of the sunshade cloth 7, so as to smooth and clean the surface of the sunshade cloth 7. The upper circular plate of the limiting post 16 is larger than the lower circular plate, so as to limit the horizontal plate 12.
[0029] In actual use, firstly, the temperature sensor 4 and the light intensity sensor 5 monitor the temperature inside the canopy 1 in real time and transmit the data to the system control device 6. When the system control device 6 issues a command to close the sunshade cloth 7, the motor device 3 starts, the winding roller 11 begins to rotate clockwise, and drives the sunshade cloth 7 to roll up. The sunshade cloth 7 drives the auxiliary rod 9 to move upward. The cleaning brush 15 and the scraper 19 are always in contact with the surface of the sunshade cloth 7 to smooth and clean the surface of the sunshade cloth 7. When the system control device 6 issues a command to open the sunshade cloth 7, the winding roller 11 rotates counterclockwise, and the auxiliary rod 9 drives the sunshade cloth 7 to move to both sides of the canopy roof 2, keeping the sunshade cloth 7 in a stretched and flat state to avoid bending and knotting.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
