[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-6 This invention provides a shade and rain shelter for assessing crop drought resistance, comprising:

[0029] The support device includes four sets of folding telescopic brackets, all of which are arranged in an L-shaped structure.

[0030] The connecting mechanism has one end of each of the four sets of folding telescopic brackets hinged to it, and a fixing component is provided between the folding telescopic brackets and the connecting mechanism to fix the folding telescopic brackets.

[0031] The winding mechanism has two sets, which are symmetrically and detachably connected to the top of the folding telescopic bracket. A plastic film 1 is wound on one of the winding mechanisms, and one end of the plastic film 1 is fixedly connected to the winding mechanism. The other end of the plastic film 1 is set on the other winding mechanism.

[0032] When this invention is in operation, the folding telescopic brackets are first opened, and the relative angles between the four folding telescopic brackets are adjusted so that the device can cover the area. Then, two sets of rewinding mechanisms are symmetrically set on the top of the four sets of folding telescopic brackets, and the plastic film 1 is unfolded to achieve the rain protection function. After use, the top plastic film is rolled up by the rewinding mechanism, and then the folding telescopic brackets are folded and retracted. This greatly reduces the footprint of the device, and the size of the device can be adjusted so that the device can be used for covering different areas.

[0033] Further optimizing the design, the folding telescopic bracket includes a vertical telescopic rod 2 and a horizontal telescopic rod 3. A first hinge seat 4 is installed at the top of the vertical telescopic rod 2. The horizontal telescopic rod 3 is hinged to the top of the vertical telescopic rod 2 via the vertical telescopic rod 2. The end of the horizontal telescopic rod 3 furthest from the vertical telescopic rod 2 is hinged to a connecting mechanism. A stop block 5 is provided at the top of the first hinge seat 4, which engages with the horizontal telescopic rod 3 for limiting movement. The arrangement of the horizontal telescopic rod 3 and the vertical telescopic rod 2 allows the device to be adjusted in height and coverage area at will. Adjusting the horizontal telescopic rod 3 adjusts both the device height and coverage area. Furthermore, to prevent water accumulation on the top of the device, it can be tilted, allowing rainwater to slide off directly, reducing the load on the device and extending its service life.

[0034] A further optimized design includes a connecting block with an annular groove 6 on its side wall. A second hinge seat 7 is slidably connected within the annular groove 6. An arc-shaped groove 8 is formed at the top of the connecting block, communicating with the annular groove 6. A mounting shaft 9 is fixedly connected to the top of the second hinge seat 7, slidably connected within the arc-shaped groove 8. A nut 10 is threaded onto the outer wall of the mounting shaft 9, abutting against the top wall of the annular groove 6. One end of the horizontal telescopic rod 3 is hinged to the second hinge seat 7. When adjusting the angle between adjacent horizontal telescopic rods 3, simply loosen the nut 10 on the corresponding second hinge seat 7, then slide the second hinge seat 7. Once the angle is appropriate, fix it with the nut 10 to secure the second hinge seat 7, ensuring the stability of the four horizontal telescopic rods 3.

[0035] Further optimization of the design includes a fixing block 11 fixedly connected to the second hinge seat 7. The fixing block 11 has a limiting groove. A mounting block 12 is fixedly connected to the lower part of one end of the horizontal telescopic rod 3. The mounting block 12 has a stepped hole 13, within which a limiting rod 14 is slidably connected. The limiting rod 14 engages with the limiting hole, and a spring 15 is fitted onto the limiting rod 14. One end of the spring 15 is fixedly connected to the limiting rod 14, and the other end is fixedly connected to the inner wall of the stepped hole 13. This fixing component ensures the device remains stable after deployment. During use, when the horizontal telescopic rod 3 rotates to a horizontal position, the limiting rod 14 inserts into the limiting groove under the action of the spring 15, thus fixing the horizontal telescopic rod 3. Simultaneously, a stop block 5 is provided at the top of the first hinge seat 4 to control the rotation angle of the horizontal telescopic rod 3 relative to the vertical telescopic rod 2, working in conjunction with the fixing component to ensure the stability of the device.

[0036] The scheme is further optimized. The winding mechanism includes a mounting plate 16 that is detachably connected to the top of the vertical telescopic rod 2. The top surface of the mounting plate 16 is rotatably connected to the winding assembly through the support base 17. The winding assemblies at the top of the two mounting plates 16 are symmetrically arranged, and the two ends of the plastic film 1 are respectively set on the two winding assemblies.

[0037] The scheme is further optimized. The winding assembly includes a first sliding sleeve 18 and a second sliding sleeve 19. The second sliding sleeve 19 is slidably disposed inside the first sliding sleeve 18. The ends of the first sliding sleeve 18 and the second sliding sleeve 19 that are far apart from each other are respectively fixedly connected to a pad 20. A threaded sleeve 21 is coaxially disposed inside the first sliding sleeve 18. The threaded sleeve 21 is fixedly connected to the pad 20 on the first sliding sleeve 18. A threaded rod 22 is coaxially disposed inside the second sliding sleeve 19. The threaded rod 22 is rotatably connected to the pad 20 on the second sliding sleeve 19. The threaded rod 22 is threadedly connected to the threaded sleeve 21. The end of the threaded rod 22 that is far away from the threaded sleeve 21 extends out of the second sliding sleeve 19. The cross-sectional shape of the pad 20 is T-shaped.

[0038] In a further optimized design, horizontal through grooves are provided on the first sliding sleeve 18 and the second sliding sleeve 19 respectively. Several sets of extrusion components are provided in the horizontal through grooves. Each extrusion component includes an extrusion block 23 that is slidably disposed in the horizontal through groove. A threaded hole is provided on the side wall of the horizontal through groove. An extrusion bolt 24 is threadedly connected in the threaded hole. One end of the extrusion bolt 24 is rotatably connected to the extrusion block 23. The plastic film 1 is fixed on the first sliding sleeve 18 and the second sliding sleeve 19 through the extrusion block 23.

[0039] In use, firstly, the two ends of the plastic mold are respectively set on the two symmetrically arranged first sliding sleeves 18 and second sliding sleeves 19. Rotate the extrusion bolt 24 to control the sliding of the extrusion block 23, and use the extrusion block 23 to extrude the plastic film 1, thereby ensuring that the plastic mold is fixed on the first sliding sleeve 18 and second sliding sleeve 19. At the same time, it is necessary to ensure that the plastic film is wound with a certain amount of allowance on one of the winding components. Then, the two winding components are respectively set on the mounting plate 16. One mounting plate 16 is fixed at both ends to the top of two adjacent vertical telescopic rods 2, and the other mounting plate 16 is fixed at both ends to the top of the other two vertical telescopic rods 2. In order to ensure that the device can clamp plastic films 1 of different areas, the winding component is set to telescopic form. In use, the relative length of the first sliding sleeve 18 and the second sliding sleeve 19 is controlled by rotating the threaded rod 22, thereby controlling the length of the winding component, so that the device can be used for plastic films 1 of different areas.

[0040] To further optimize the solution, in order to avoid the plastic film 1 being replaced multiple times and the length of the plastic film 1 being greater than the length of the winding assembly, a certain amount of allowance is reserved at both ends of the plastic film 1. At the same time, in order to avoid damage to the plastic film 1 by folding, the allowance needs to be controlled to not be too large. In this way, after the length of the winding assembly changes, the plastic film 1 can directly extend to supplement the required area, thereby making the top of the device form an irregular quadrilateral, which improves the applicability of the device.

[0041] To further optimize the design, a base 25 is installed at the bottom of the vertical telescopic rod 2.

[0042] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0043] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
