Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse-related devices, and in particular to a greenhouse light regulation device. Background Technology

[0002] In summer, plants are easily damaged by excessive sunlight, so measures need to be taken to regulate light, including the use of shade nets. Shade nets are a type of shading material that effectively blocks sunlight, reducing the temperature and light intensity inside the greenhouse. In summer, shade nets with moderate density and low light transmittance should be chosen to avoid excessive shading and affecting the normal growth of plants.

[0003] Traditionally, when using shade nets, a layer is placed over the top of the greenhouse, which completely blocks the view inside the greenhouse. This makes it impossible to adjust the shade nets according to the direction of sunlight, resulting in poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a greenhouse light regulation device that can be adaptively adjusted according to usage needs, thus enhancing its practicality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A shade net is included, which is slidably connected to the inner wall of the greenhouse roof. The shade net includes a central mesh and mesh belts on opposite sides of the mesh. Several mesh belts are fixed at equal intervals to the ends of the mesh. Rolling assemblies are respectively provided on the bottom edges of opposite sides of the greenhouse. Each rolling assembly includes a rotating shaft, and several limiting ring plates are fixedly fitted around the rotating shaft at equal intervals. The number of limiting ring plates is the same as the number of mesh belts on one side of the mesh. The mesh belts are rolled onto the limiting ring plates one-to-one.

[0006] A further feature of this invention is that the limiting ring plate has a recessed groove on its circumferential surface, and the mesh belt is positioned in the recessed groove.

[0007] A further feature of this invention is that: on the other opposite arc-shaped edge of the greenhouse perpendicular to the axis of rotation, there are parallel arc-shaped support plates; the two support plates are fixed to the opposite vertical plates of the greenhouse; and the opposite ends of the shade net are attached to the upper surface of the support plates.

[0008] A further feature of this invention is that: the upper surface of the support plate is provided with concave grooves at even intervals, and a U-shaped support rod is provided in the groove; a rotating roller is rotatably connected between the two side rods of the support rod.

[0009] A further feature of this invention is that: vertical grooves are recessed on the inner walls of opposite sides of the groove two; protruding rods are provided on opposite sides of the support rod; the protruding rods are slidably connected to the vertical grooves; the bottom of the support rod is connected to one end of a spring; the other end of the spring is connected to the bottom surface of the groove two; and the spring drives the support rod away from the bottom surface of the groove two.

[0010] A further feature of this invention is that: a driving synchronous pulley and a driven synchronous pulley are coaxially fixed at the ends of the two rotating shafts, and a synchronous belt is sleeved on the driving synchronous pulley and the driven synchronous pulley; the driving synchronous pulley is coaxially fixedly connected to the output shaft of the motor.

[0011] The beneficial effects of this utility model are:

[0012] 1. When the sunlight is strong and the entire greenhouse roof needs to be covered with shade netting, start motor one. The active synchronous pulley drives the driven synchronous pulley to rotate, driving the entire shade netting to cover the greenhouse roof. At this time, the netting tape at both ends of the netting is wound on the two rotating shafts. Similarly, when the sunlight is strong on only one side of the greenhouse and shading is needed, rotate the netting to the greenhouse roof on that side. The bottom surface of the greenhouse roof on the other side is covered with spaced netting tape. The shading can be adjusted according to the external conditions, making it more practical and beneficial to the growth of trees.

[0013] 2. By setting an arc-shaped support plate, the mesh belts and mesh fabric at both ends can fit against the support plate when rotating. By setting a spring, the support plate is driven to rise, so that the rotating roller fits against the shade net, which can tighten the shade net and keep the shade net flat.

[0014] 3. By setting a groove on the rotating shaft, the mesh belt is rolled into the groove. While ensuring that the shading area can be adjusted at any time, the entire shading net remains flat during rotation, achieving a better shading effect.

[0015] 4. The protruding rod slides in the vertical groove to limit the position of the support rod. Attached Figure Description

[0021] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: A greenhouse light regulation device, such as... Figure 1-3 As shown, the structure includes a shade net 1, which is slidably connected to the inner wall of the roof of a greenhouse 2. The shade net 1 includes a central mesh 101 and mesh belts 102 on opposite sides of the mesh 101. Several mesh belts 102 are evenly spaced and fixed to the ends of the mesh 101. Rolling assemblies 3 are respectively provided on the bottom edges of opposite sides of the greenhouse 2. Each rolling assembly 3 includes a rotating shaft 31, and several limiting ring plates 32 are evenly spaced and fixed outside the rotating shaft 31. The number of limiting ring plates 32 is the same as the number of mesh belts 102 on one side of the mesh 101. Each mesh belt 102 is rolled onto the limiting ring plate 32. A groove 33 is recessed on the circumferential surface of the limiting ring plate 32. The mesh belts 102 are engaged and rolled into the groove 33. By providing the groove 33 on the rotating shaft 31, the mesh belts 102 are rolled onto the groove 33 one by one. In groove 33, while ensuring that the shading area can be adjusted at any time, the entire shading net 1 remains flat during rotation, achieving a better shading effect. When the sunlight is strong and the entire roof of the greenhouse 2 needs to be covered with the shading net 1, the motor 5 is started, and the active synchronous pulley drives the driven synchronous pulley to rotate, driving the net 101 of the shading net 1 to be fully exposed and blocking the roof of the greenhouse 2. At this time, the net belts 102 at both ends of the net 101 are wound on the two rotating shafts 31. Similarly, when the sunlight is strong on only one side of the greenhouse 2 and shading is needed, the net 101 is rotated to the roof of the greenhouse 2 on that side, and the bottom surface of the roof of the other side of the greenhouse 2 is covered with the spaced net belts 102. The shading can be adjusted according to the external conditions, making it more practical and beneficial to the growth of trees.

[0023] Furthermore, parallel arc-shaped support plates 4 are provided on the other opposite arc edge of the greenhouse 2 perpendicular to the rotation axis 31. The two support plates 4 are fixed to the opposite vertical plates of the greenhouse 2. By setting the arc-shaped support plates 4, it is beneficial for the two ends of the mesh belt 102 and the mesh cloth 101 to adhere to the support plates 4 when rotating. By setting the spring 11, the support plates 4 are driven to rise, so that the rotating roller 8 adheres to the shade net 1, which can tighten the shade net 1 and keep the shade net 1 flat. The two opposite ends of the shade net 1 adhere to the upper surface of the support plate 4, and the upper surface of the support plate 4 is evenly spaced. A concave groove 6 is provided, and a U-shaped support rod 7 is provided in the groove 6. A rotating roller 8 is rotatably connected between the two side rods of the support rod 7. Vertical grooves 9 are provided in the concave inner walls on opposite sides of the groove 6. A protruding rod 10 is provided on the opposite side of the support rod 7. The protruding rod 10 is snapped and slidably connected in the vertical groove 9. The bottom rod of the support rod 7 is connected to one end of a spring 11, and the other end of the spring 11 is connected to the inner bottom surface of the groove 6. The spring 11 drives the support rod 7 away from the inner bottom surface of the groove 6, and the protruding rod 10 slides in the vertical groove 9 to limit the position of the support rod 7.

[0024] A further feature of this invention is that: a driving synchronous pulley and a driven synchronous pulley are coaxially fixed at the ends of the two rotating shafts 31, and a synchronous belt is provided over the driving synchronous pulley and the driven synchronous pulley; the driving synchronous pulley is coaxially fixedly connected to the output shaft of the motor 5.

[0025] The working principle of a greenhouse light regulation device:

[0026] When the sunlight is strong and the entire roof of greenhouse 2 needs to be covered with shade netting 1, start motor 5. The active synchronous pulley drives the driven synchronous pulley to rotate, driving the entire netting 101 of the shade netting 1 to be exposed and block the roof of greenhouse 2. At this time, the netting belts 102 at both ends of the netting 101 are wound on the two rotating shafts 31. Similarly, when the sunlight is strong on only one side of greenhouse 2 and shading is needed, rotate the netting 101 to the roof of greenhouse 2 on that side. The bottom surface of the roof of greenhouse 2 on the other side is covered with the spaced netting belts 102. The shading can be adjusted according to the external conditions, making it more practical and beneficial to the growth of trees.
