Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically to an automatic control shading device for vegetable planting greenhouses. Background Technology

[0002] In vegetable cultivation, light intensity has a significant impact on the growth and development of vegetables. Different vegetable varieties have different light requirements at different growth stages. Excessive sunlight may cause vegetables to scorch, lose water, and even affect quality and yield. Therefore, providing appropriate shade for vegetables is essential during hot summers or periods of intense sunlight.

[0003] For example, Chinese Patent CN220733746U discloses an automatic control shading device for vegetable greenhouses, including a support mechanism and a shading mechanism. The shading mechanism is connected to the surface of the support mechanism and includes a drive unit and a control unit. The drive unit is connected to the surface of the support mechanism, and the control unit is connected to the interior of the support mechanism. This automatic control shading device for vegetable greenhouses moves the shading net and traction rope by sliding a connecting slide plate on top of the support frame, ensuring the shading net's ends fit snugly against the support frame. This prevents the shading net from warping or becoming misaligned in windy conditions, improving the shading effect. A timer controller electrically connected to the first and second motor housings allows the grower to set a timer to control the movement of the shading net, creating a closed or open state, thus improving the device's automation efficiency and reducing the frequency of manual labor.

[0004] While the above example demonstrates how the shade net can be used to provide shade by pulling it with a traction rope, the degree of shading provided by the net is fixed and cannot be precisely adjusted according to real-time changes in light intensity. This makes it impossible to provide the most suitable growing environment for vegetables and presents certain inconveniences in its use. Utility Model Content

[0005] This invention provides an automatic control shading device for vegetable greenhouses to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An automatic control shading device for a vegetable greenhouse includes a vegetable greenhouse, the surface of which is provided with a shading mechanism, the shading mechanism including a fixed frame, a rotating shaft rotatably connected inside the fixed frame, and a shading plate fixedly connected to the surface of the rotating shaft.

[0008] A further improvement of the present invention is that: a first pulley is fixedly connected to one end of the rotating shaft, and a first belt is attached to the surface of the first pulley.

[0009] A further improvement of this utility model is that a second pulley is attached to one end of the first belt, and a motor is fixedly connected to one side of the second pulley.

[0010] A further improvement of the present invention is that: a motor housing with a heat dissipation hole at one end is fixedly connected to the surface of the motor, a second belt is attached to the surface of the first pulley, and multiple first pulleys are connected to each other through the second belt.

[0011] A further improvement of this utility model is that the vegetable greenhouse includes a greenhouse body, and a connecting rope is fixedly connected to the top of the inner cavity of the greenhouse body.

[0012] A further improvement of this utility model is that: a light sensor with a built-in information processing module is fixedly connected to the lower end of the connecting rope, and the light sensor is electrically connected to the motor.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This utility model provides an automatic control shading device for vegetable greenhouses. When shading the greenhouse, a light sensor detects the light intensity inside the greenhouse in real time. When the light intensity is strong, a motor drives the shading plate to rotate, adjusting the angle of the shading plate to achieve the shading effect. At the same time, the shading effect is different at different angles, allowing the shading plate to be adjusted to a suitable angle according to the light intensity to provide a suitable shading effect. In addition, the shading plate can also provide a certain degree of protection for the vegetable greenhouse during hailstorms in severe convective weather, making it easier to use.

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figure 1-5 As shown, this utility model provides an automatic control shading device for vegetable greenhouses, including a vegetable greenhouse, a shading mechanism on the surface of the vegetable greenhouse, the shading mechanism including a fixed frame 21, a rotating shaft 22 rotatably connected inside the fixed frame 21, a shading plate 23 fixedly connected to the surface of the rotating shaft 22, a first pulley 24 fixedly connected to one end of the rotating shaft 22, and a first belt 25 overlapping the surface of the first pulley 24.

[0024] In this embodiment, the light intensity inside the greenhouse 11 is detected by the light sensor 13. When the information processing module inside the light sensor 13 compares the current light intensity with the preset intensity, if the current light intensity is strong, the motor 27 is started, which drives the first belt 25 to rotate through the second pulley 26. This causes the first pulley 24 to adjust the angle of the multiple shade plates 23 simultaneously through multiple second belts 28, reducing the tilt angle of the shade plates 23 and thus reducing the gap between the multiple shade plates 23, thereby enhancing the shading effect. When the light intensity inside the greenhouse is weak, the motor 27 causes the second pulley 26 to rotate in the opposite direction, increasing the tilt angle of the shade plates 23 and thus increasing the distance between the shade plates 23, reducing the shading intensity of the shade plates 23, and making the light intensity inside the greenhouse 11 more suitable for vegetable growth.

[0025] Example 2

[0026] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, it includes a vegetable growing greenhouse, the surface of which is provided with a shading mechanism. The shading mechanism includes a fixed frame 21, a rotating shaft 22 is rotatably connected inside the fixed frame 21, a shading plate 23 is fixedly connected to the surface of the rotating shaft 22, a first pulley 24 is fixedly connected to one end of the rotating shaft 22, a first belt 25 is attached to the surface of the first pulley 24, a second pulley 26 is attached to one end of the surface of the first belt 25, a motor 27 is fixedly connected to one side of the second pulley 26, a motor housing 29 with a heat dissipation hole at one end is fixedly connected to the surface of the motor 27, a second belt 28 is attached to the surface of the first pulley 24, and multiple first pulleys 24 are connected to each other through the second belt 28.

[0027] In this embodiment, the light intensity inside the greenhouse 11 is detected by the light sensor 13. When the information processing module inside the light sensor 13 compares the current light intensity with the preset intensity, if the current light intensity is strong, the motor 27 is started, which drives the first belt 25 to rotate through the second pulley 26. This causes the first pulley 24 to adjust the angle of the multiple shade plates 23 simultaneously through multiple second belts 28, reducing the tilt angle of the shade plates 23 and thus reducing the gap between the multiple shade plates 23, thereby enhancing the shading effect. When the light intensity inside the greenhouse is weak, the motor 27 causes the second pulley 26 to rotate in the opposite direction, increasing the tilt angle of the shade plates 23 and thus increasing the distance between the shade plates 23, reducing the shading intensity of the shade plates 23, and making the light intensity inside the greenhouse 11 more suitable for vegetable growth.

[0028] Example 3

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, it includes a vegetable growing greenhouse, the surface of which is provided with a shading mechanism, the shading mechanism includes a fixed frame 21, a rotating shaft 22 is rotatably connected inside the fixed frame 21, a shading plate 23 is fixedly connected to the surface of the rotating shaft 22, a first pulley 24 is fixedly connected to one end of the rotating shaft 22, a first belt 25 is overlapped on the surface of the first pulley 24, the vegetable growing greenhouse includes a greenhouse body 11, a connecting rope 12 is fixedly connected to the top of the inner cavity of the greenhouse body 11, a light sensor 13 with a built-in information processing module is fixedly connected to the lower end of the connecting rope 12, and the light sensor 13 is electrically connected to a motor 27.

[0030] In this embodiment, the light intensity inside the greenhouse 11 is detected by the light sensor 13. When the information processing module inside the light sensor 13 compares the current light intensity with the preset intensity, if the current light intensity is strong, the motor 27 is started to adjust the shading intensity. When strong convective weather occurs, the motor 27 can be started to reduce the distance between the shading panels 23 to the minimum. The shading panels 23 can provide a certain degree of protection for the greenhouse 11, preventing hail from directly damaging the greenhouse and making it easier to use.

[0031] The working principle of the automatic shading device used in this vegetable greenhouse will be explained in detail below.

[0032] like Figure 1-5As shown, during use, the light intensity inside the greenhouse 11 is detected by the light sensor 13. When the information processing module inside the light sensor 13 compares the current light intensity with the preset intensity, if the current light intensity is strong, the motor 27 is started, which drives the first belt 25 to rotate through the second pulley 26. This causes the first pulley 24 to adjust the angle of the multiple shade plates 23 simultaneously through multiple second belts 28, reducing the tilt angle of the shade plates 23 and thus reducing the gap between the multiple shade plates 23, enhancing the shading effect. When the light intensity inside the greenhouse is weak, the motor 27 causes the second pulley 26 to rotate in the opposite direction, increasing the tilt angle of the shade plates 23 and thus increasing the distance between the shade plates 23, weakening the shading intensity of the shade plates 23, making the light intensity inside the greenhouse 11 more suitable for vegetable growth. When strong convective weather occurs, the motor 27 can be started to reduce the distance between the shade plates 23 to the minimum. The shade plates 23 can provide a certain degree of protection for the greenhouse 11, preventing hail from directly damaging the greenhouse and making it easier to use.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
