[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-4 As shown, an adjustable light intensity greenhouse shading device includes a mounting frame 1, a retractable component 4, a side plate 41, a rotating shaft 44, a torsion spring 43, a shading curtain 3, and a sliding component 2. The mounting frame 1 is detachably installed on the greenhouse using bolts and flanges, etc. Figure 1 As shown, the frame is designed in a U-shape to facilitate the sunshade of the curtain 3. In order to reduce the bending and corrosion of the mounting frame 1 during use, the mounting frame 1 should be made of hard metal material with an anti-corrosion coating.

[0026] In order to realize the automatic retraction function of the blind curtain 3, the retraction component 4 is set on the mounting bracket 1.

[0027] The retractable component 4 includes side plates 41, rotating shafts 44, and torsion springs 43. Specifically, the side plates 41 are detachably connected to both sides of the top of the mounting frame 1 by bolts or the like. The side plates 41 are symmetrically distributed along the longitudinal central axis of the mounting frame 1, and rotating shafts 44 are rotatably connected between adjacent side plates 41. The rotating shafts 44 are as follows: Figure 2 The design shown is cylindrical, with torsion springs 43 wound around both ends of the rotating shaft 44. Without external force, the torsion springs 43 will roll up the curtain 3 on the surface of the rotating shaft 44.

[0028] To achieve the shading effect, part of the shade curtain 3 is wrapped around the retractable part 4. To ensure that the shade curtain 3 can be rolled up, it should be made of soft fabric or plastic sheeting or other soft materials that can block light. The side panel 41 rotates under force to roll up the shade curtain 3. Compared with the rigid light-blocking board, the soft material design of the shade curtain 3 makes it easier to replace and also reduces the overall weight of the greenhouse roof, thereby increasing the safety of the greenhouse during use. At the same time, the soft shade curtain 3 also makes it easy to adjust the angle of light. During installation, the part of the shade curtain 3 can be pulled against the top surface of the glass greenhouse to avoid light leakage through gaps, so as to adapt to the sunlight requirements of different plants.

[0029] In order to move the blind 3 by Figure 1 Pull to Figure 3At the designated location, the sliding member 2 is placed on both sides of the blind curtain 3, and part of the sliding member 2 is inserted into the blind curtain 3. When the sliding member 2 moves, it will cause the blind curtain 3 to unfold to adjust the light intensity.

[0030] Mounting bracket 1 has a drive source, the output end of which is detachably connected to one side of sliding member 2. The drive source is connected to an external power supply and control panel via wires. The drive source is a cylinder. It should be noted that the working principle of the cylinder is to convert the pressure energy of compressed air into mechanical energy, and drive the mechanism to achieve reciprocating linear motion, oscillation, or rotational motion. The cylinder mainly consists of a cylinder body, piston, and sealing ring. Compressed air causes the piston to move, and the direction of piston rod movement is changed by changing the air intake direction. When selecting a model, a model suitable for the equipment should be selected. The above is the existing technology and will not be repeated below. The drive source drives the sliding member 2 to move to open the curtain 3.

[0031] The pull-out component 4 also includes a connecting part 42 connected to the rotating shaft column 44. The connecting part 42 is connected to the curtain 3. The part where the curtain 3 and the connecting part 42 are connected should have a hook and loop fastener that can be glued to the connecting part 42. The connecting part 42 and the curtain 3 have a hook side and a loop side, respectively, to achieve the adhesive effect and facilitate the replacement of curtains 3 of different materials in the future.

[0032] The effect achieved by the entire first embodiment is that, during use, the drive source is controlled by the control panel, and the drive source pushes the sliding part 2 on the mounting bracket 1 to move the curtain 3. Figures 1 to 3 The location changes, or is caused by Figures 3 to 1 It makes changes to achieve the function of adjusting light intensity.

[0033] Example 2

[0034] like Figure 1-4 As shown, a greenhouse shading device with adjustable light intensity has a mounting frame 1 with two sliding grooves 11 for sliding members 2. The sliding grooves 11 extend longitudinally to the outside of the mounting frame 1, wherein the sliding grooves 11 are as follows: Figure 1 As shown, the components are symmetrically distributed along the longitudinal central axis of the mounting bracket 1, which facilitates the sliding insertion of the sliding component 2.

[0035] The sliding member 2 includes a support plate 23 that is slidably inserted into the slide groove 11, the bottom of which extends beyond the mounting bracket 1, such as... Figure 2 As shown, the support plate 23 has a "T" shaped design, which facilitates the insertion of the slide groove 11.

[0036] One side of the support plate 23 is connected to a limiting plate 21, and the limiting plate 21 and the mounting bracket 1 are slidably connected, wherein the limiting plate 21 is as follows: Figure 2As shown, it has an "L" shaped design, and the limiting plate 21 and the support plate 23 are connected by bolts. When connected, the support plate 23 and the limiting plate 21 will move as shown. Figure 2 As shown, it can slide while being plugged into the mounting bracket 1.

[0037] The support plate 23 is integrally formed on one side of the curtain 3 and has a slot 22, in which a support column is inserted between two adjacent slots 22.

[0038] To ensure that the curtain 3 moves with the sliding member 2, a through groove is provided at the position of the insertion slot 22 for the support column to be inserted. The through groove and the support column are inserted, so that when the sliding member 2 is driven by the driving source, the curtain 3 is opened.

[0039] The bottom of the mounting bracket 1 is provided with four support legs 12. The plane where the lowest point of the support leg 12 is located is coplanar with the plane where the lowest point of the support plate 23 is located, which facilitates the support and installation of the mounting bracket 1 without affecting the displacement of the sliding member 2.

[0040] The effect achieved by the entire second embodiment is that the plane where the lowest point of the support leg 12 is located and the plane where the lowest point of the support plate 23 is located are coplanar. This facilitates the support and installation of the mounting bracket 1 without affecting the displacement of the sliding member 2. In order to ensure that the curtain 3 will follow the displacement of the sliding member 2, a through groove and a support column are provided so that when the sliding member 2 is driven by the drive source, it will drive the curtain 3 to unfold. At the same time, it has an "L" shape design when in use. The limiting plate 21 and the support plate 23 are connected by bolts. When connected, the support plate 23 and the limiting plate 21 will move as shown in the figure. Figure 2 As shown, it can slide while being plugged into the mounting bracket 1.

[0041] Working principle: When using this greenhouse shading device, an external power supply is connected. First, the plane where the lowest point of the support leg 12 is located and the plane where the lowest point of the support plate 23 is located are coplanar. This facilitates the support and installation of the mounting frame 1 without affecting the displacement of the sliding member 2. To ensure that the shading curtain 3 moves with the sliding member 2, a through groove and support column are provided. This allows the sliding member 2 to drive the shading curtain 3 to unfold when driven by the drive source. During use, it has an "L" shape design. The limiting plate 21 and the support plate 23 are connected by bolts. When connected, the support plate 23 and the limiting plate 21 will move as shown in the image. Figure 2 As shown, it can slide while being plugged into the mounting bracket 1;

[0042] Secondly, the drive source is controlled via the control panel. The drive source pushes the sliding piece 2 on the mounting bracket 1, which in turn moves the blind curtain 3. Figures 1 to 3 The location changes, or is caused by Figures 3 to 1 By making changes, the light intensity can be adjusted, thus completing the function of the greenhouse shading device.
