[0002] A glass greenhouse is a type of greenhouse that uses glass as its light-transmitting material. Among cultivation facilities, glass greenhouses have the longest service life and are suitable for use in various regions and climates.

However, existing shading devices are generally shade cloths or shade covers, which are not convenient to deploy and store. Furthermore, these cloths or covers cannot evenly adjust the light intensity across the entire greenhouse according to the required light intensity, resulting in severely insufficient light in the shaded areas and excessive light intensity in the unshaded areas, thus affecting the normal growth of plants inside the greenhouse.

[0039] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.
[0040] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0041] like Figure 1 As shown, this utility model provides a glass greenhouse shading system for shading a glass greenhouse 100. When the light intensity is too high, the shading system reduces the light intensity inside the glass greenhouse 100 and lowers the internal temperature.
[0042] See Figure 1The glass greenhouse shading system includes a glass greenhouse 100 and a first shading device 1 installed inside the glass greenhouse 100. The shading system is an indoor shading device, and its shape is the same as the horizontal cross-section of the glass greenhouse 100, ensuring shading effect while preventing erosion from the natural environment and improving the durability of the shading system. When the glass greenhouse 100 has a large area, multiple first shading devices 1 can be installed. The first shading device 1 includes a mounting frame 11, multiple shading panels 12, and a drive mechanism. The mounting frame 11 is installed inside the glass greenhouse 100. Multiple shading panels 12 are rotatably mounted on the top of the mounting frame 11 via mounting shafts 14. Each shading panel 12 is a long rectangular plate, with both ends rotatably mounted on the mounting frame 11 via mounting shafts 14. The shading panels 12 can rotate around the mounting shafts 14, and the mounting shafts 14 of the multiple shading panels 12 are parallel to each other and all located in the same horizontal plane. The drive mechanism is mounted on the mounting frame 11, and multiple mounting shafts 14 are connected to the drive mechanism. The drive mechanism drives the mounting shafts 14 to rotate, thereby driving multiple sunshade panels 12 to rotate synchronously. Under the action of the drive mechanism, the sunshade panels 12 can rotate between vertical and horizontal states without the need to unfold and retract the first sunshade device 1. By controlling the angle of the sunshade panel 12, the area of shading can be controlled, thereby controlling the amount of light transmitted inside the glass greenhouse 100. This achieves stepless and uniform light intensity adjustment, avoiding the situation where the shaded part has insufficient light while the unshaded part has excessive light intensity.
[0043] Furthermore, when the sunshade 12 rotates to a horizontal position under the action of the drive mechanism, multiple sunshade 12s are sequentially spliced together to form a flat plate structure 15. A certain gap is left between adjacent sunshade 12s to avoid mutual interference. Alternatively, flexible thin sealing strips are provided on the edges of the sunshade 12s, and adjacent sunshade 12s overlap each other through the sealing strips. When the sunshade 12s rotate, they are deformed by compression to avoid mutual interference. The glass greenhouse 100 is divided into two independent spaces, upper and lower, by the flat plate structure 15, with only a partial gap connecting the two spaces. During the day, the flat plate structure 15 can completely shade the top of the glass greenhouse 100, effectively blocking short-wave sunlight; at night, it can reflect long-wave sunlight from the ground, providing insulation for the glass greenhouse 100; effectively reducing the energy consumption for temperature control in the glass greenhouse 100. When the sunshade 12 is rotated to a completely vertical position, the two independent spaces above and below are completely connected. Between the vertical and horizontal positions, the sunshade 12 is rotated by a drive mechanism to change its angle. The angle of the sunshade 12 is adjusted according to the angle of sunlight. When the sunlight is almost parallel to the sunshade 12, the glass greenhouse 100 has the maximum amount of light transmission. The larger the angle between the two, the smaller the amount of light transmission in the glass greenhouse 100.
[0044] like Figure 2As shown, the sunshade 12 includes a connecting sleeve 120 and a first substrate 121 and a second substrate 122 symmetrically arranged on both sides of the connecting sleeve 120. The connecting sleeve 120 is sleeved on the mounting shaft 14, and a locking bolt 123 is threadedly connected to the connecting sleeve 120. The mounting shaft 14 is provided with an internal threaded hole, and the locking bolt 123 is threadedly connected to the internal threaded hole, which improves the convenience of disassembly and assembly, and at the same time ensures that the first substrate 121 and the second substrate 122 rotate synchronously with the mounting shaft 14. When the sunshade 12 is in a horizontal state, the first surfaces of the first substrate 121 and the second substrate 122 are both facing upwards, and the second surfaces of the first substrate 121 and the second substrate 122 are both facing downwards. The first surfaces of the first substrate 121 and the second substrate 122 serve as the light-facing surfaces, and each is provided with a light-shielding plate 124, which can effectively block the short waves of the sun. The light-shielding area of the light-shielding plate 124 can be controlled by adjusting the angle of the first substrate 121 and the second substrate 122, thereby controlling the amount of light transmitted. The shading plate 124 is preferably a thin plastic sheet to reduce the weight of the shading plate 12. The second side of the first substrate 121 and the second substrate 122 serves as the backlight surface, and each is provided with an insulation plate 125. An aluminum film 126 is provided on the lower surface of the insulation plate 125. After the earth's surface absorbs short-wave solar radiation, it heats up and releases heat energy outward in the form of long waves (wavelength 3~120 micrometers), which is thermal infrared radiation. At night, the long waves from the earth's surface are reflected by the insulation plate 125 and the aluminum film 126, which insulates the glass greenhouse 100 and can effectively cope with the large temperature difference between day and night.
[0045] like Figure 1 and Figure 3 As shown, the mounting frame 11 includes multiple uprights 111 and a pair of crossbeams 112. The uprights 111 are vertically installed inside the glass greenhouse 100, close to the side wall of the glass greenhouse 100. The lower end of the uprights 111 is inserted into the bottom surface and fixed by casting, facilitating the modification of the existing glass greenhouse 100. Alternatively, the strength of the uprights 111 of the glass greenhouse 100 can be increased during the construction of the glass greenhouse 100, and the uprights 111 of the glass greenhouse 100 can be directly used as the uprights 111 of the mounting frame 11, reducing the space occupied by the uprights 111 of the mounting frame 11. The pair of crossbeams 112 are horizontally installed at the upper end of the uprights 111. The two ends of the mounting shafts 14 are respectively connected to the pair of crossbeams 112 through bearings. The drive mechanism is installed on the first crossbeam 112 of the pair of crossbeams 112, and the ends of the multiple mounting shafts 14 located on the first crossbeam 112 are all connected to the drive mechanism. In practice, the shading system can be divided into multiple mounting frames 11 according to the actual area of the glass greenhouse 100. Each mounting frame 11 is equipped with a shading plate 12 and a drive mechanism for easy zone control.
[0046] like Figure 3As shown, the drive mechanism includes a servo motor 131, a reducer 132, a drive shaft 133, and multiple worm gear assemblies 134. The servo motor 131 is mounted on the first crossbeam 112, and the drive shaft 133 is arranged along the length of the first crossbeam 112. Both ends of the drive shaft 133 are rotatably connected to the first crossbeam 112 via bearings. Preferably, multiple bearings for connecting to the first crossbeam 112 are spaced apart on the drive shaft 133 to improve the rotational stability of the drive shaft 133. The output shaft of the servo motor 131 is connected to the drive shaft 133 via the reducer 132, and the end of the mounting shaft 14 is connected to the drive shaft 133 via the worm gear assembly 134. Specifically, the worm gear is mounted on the end of the mounting shaft 14, and the worm is connected to the drive shaft 133. The meshing between the worm gear and the worm enables power transmission while reducing the lead angle of the worm to achieve self-locking, ensuring that the sunshade 12 can be locked at a set angle.
[0047] Preferably, the reducer 132 includes two output shafts, and the drive shaft 133 is decomposed into a first drive shaft 133 and a second drive shaft 133 symmetrically arranged with the reducer 132 as the center of symmetry. The reducer 132 is located between the first drive shaft 133 and the second drive shaft 133, and the first drive shaft 133 and the second drive shaft 133 are respectively connected to the two output shafts of the reducer 132 in a one-to-one correspondence, thereby improving the stability of the drive.
[0048] like Figure 1 and Figure 4 As shown, the glass greenhouse shading system also includes a second shading device 2 installed inside the glass greenhouse 100. The second shading device 2 includes multiple roller blind mechanisms installed on the mounting frame 11. The multiple roller blind mechanisms are arranged sequentially along the inner side of the glass greenhouse 100 to shade the side walls of the glass greenhouse 100. Further, the roller blind mechanism includes a roller blind motor 21, a roller tube 22, a shading cloth 23, and a base rod 24. The roller tube 22 is horizontally installed on a pair of uprights 111 of the mounting frame 11 via the roller blind motor 21, or directly installed on the uprights 111 of the glass greenhouse 100. The upper end of the shading cloth 23 is connected to the roller tube 22, and the lower end of the shading cloth 23 is connected to the base rod 24. The length of the shading cloth 23 is controlled by a servo motor 131, thereby controlling the shading area.
