Description

Technical Field

[0001] The utility model relates to the field of greenhouses, in particular to a device for regulating the uniform distribution of light inside a greenhouse. Background Art

[0002] Greenhouses, also known as hothouses, refer to facilities that are light-transmitting, heat-insulating (or heating) and used to grow plants. The principle of greenhouses using sunlight is to lock in the heat of sunlight, raise the temperature inside the greenhouse, and meet the growth of crops. During the day, sunlight will penetrate the greenhouse film and glass into the greenhouse, absorbing the heat of solar radiation to increase the temperature inside the greenhouse. When the temperature rises, the long-wave radiation heat reflected from the ground cannot be dissipated through the greenhouse, thereby reducing heat loss to achieve the purpose of warming. In this way, a suitable growth environment can be created for crops that are not suitable for growth in the current season, thereby increasing crop yields.

[0003] However, in actual applications, it is easy for the angle of sunlight to change due to seasonal reasons, resulting in the situation that some parts of the greenhouse are still not illuminated when the weather is clear, which eventually leads to abnormal plant development. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

[0005] To achieve the above-mentioned invention purpose, the technical solution of the utility model is: a device for adjusting the uniform distribution of light inside a greenhouse, comprising a greenhouse body, wherein a support frame is horizontally arranged at the upper part of the interior of the greenhouse body. A plurality of groups of position-adjustable light lamps are arranged at the lower end of the support frame, and each group of the light lamps is connected to the support frame through an adjustment mechanism that is slidably arranged with the support frame. The adjustment mechanism comprises a displacement unit and a lifting unit, and the movement of the light lamp is controlled by the displacement unit and the lifting unit.

[0024] See also Figure 1-Figure 4 , the greenhouse internal illumination uniformity adjustment device of this embodiment automatically or manually controls the position and height movement of the illumination lamp 3 to achieve the change of the illumination position and illumination area. Ensure that the interior of the greenhouse is always in an illuminated state, avoid the situation that there is a position inside the greenhouse that cannot be illuminated, and automatically or manually supplement the illumination of the unilluminated area to ensure the normal growth of plants. In this embodiment, it mainly includes a greenhouse body 1, and the upper part of the greenhouse body 1 is generally triangular cone-shaped. A support frame 2 is horizontally arranged at the upper part of the interior of the greenhouse body 1. The support frame 2 is a sun-shaped structure and is horizontally fixedly arranged on the upper side of the interior of the greenhouse body 1, and the middle crossbeam part of the support frame 2 is arranged along the length direction of the greenhouse body 1. The greenhouse body 1 can be supported by the support frame 2, and an assembly base is provided for the additional mechanism. A plurality of groups of position-adjustable illumination lamps 3 are arranged at the lower end of the support frame 2. The number and position of the illumination lamps 3 can be flexibly set according to actual conditions. A control module and a plurality of photosensitive sensors arranged in the greenhouse body 1 are also provided. The photosensitive sensor feeds back the light signal to the control module and the position of the photosensitive sensor can be flexibly set according to the actual situation.

[0025] To adjust the position of the lighting fixture. Figure 1 and Figure 2In this embodiment, each group of the illumination lamps 3 is connected to the support frame 2 through an adjustment mechanism 4 that is slidably arranged with the support frame 2. The adjustment mechanism 4 includes a displacement unit 41 and a lifting unit 42, and the movement of the illumination lamps 3 is controlled by the displacement unit 41 and the lifting unit 42. The displacement unit 41 includes a guide rod 411 fixedly arranged at the top of the middle beam of the support frame 2 along its length direction, a first screw rod 412 that is rotatably arranged with the support frame 2 is arranged above the guide rod 411, and a first bidirectional motor 413 that drives the first screw rod 412 is arranged at the bottom of the support frame 2. The first bidirectional motor 413 is centrally controlled by a control module. A displacement rack 414 is horizontally arranged between the middle beam part and the side beam of the support frame 2. The number and position of the displacement rack 414 can be flexibly arranged according to actual conditions. One end of the displacement rack 414 located on the middle beam is sleeved on the first screw rod 412 and the guide rod 411 and is threadedly arranged with the first screw rod 412. The other end of the displacement rack 414 is rotatably arranged with a roller 415 that abuts against the side beam. The first bidirectional motor 413 drives the first screw rod 412 to rotate, so that the displacement frame 414 cooperates with the roller 415 to move on the support frame 2. In this process, the roller 415 reduces the friction resistance and the guide rod 411 plays a guiding role.

[0026] To adjust the height of the lighting fixture. Figure 1-Figure 3 In this embodiment, at least one displacement plate 416 is horizontally fixedly provided in the middle of the displacement frame 414 along the length direction of the support frame 2, and a slide groove 417 is provided at the bottom end of the displacement plate 416 along its length direction. A second screw rod 418 is rotatably provided inside the slide groove 417 along its length direction, and a second bidirectional motor 419 driving the second screw rod 418 is fixedly provided at the end of the displacement plate 416. The second bidirectional motor 419 is centrally controlled by the control module. The lifting unit 42 includes a lifting box 421 that slides in the slide groove 417 and is threadedly provided with the second screw rod 418. The second bidirectional motor 419 drives the second screw rod 418 to rotate, so that the lifting box 421 moves in the slide groove 417, thereby achieving fine adjustment of the position of the lighting lamp 3. The lifting box 421 is provided with a rope-winding rod 422 for rotation inside, and a bottom plate 424 is connected to the bottom of the lifting box 421 through at least one rope 423 wound on the rope-winding rod 422. The illumination lamp 3 is mounted on the bottom plate 424, and a third bidirectional motor 425 for driving the rope-winding rod 422 to rotate is fixedly provided on the side of the lifting box 421. The third bidirectional motor 425 is centrally controlled by the control module. The third bidirectional motor 425 drives the rope-winding rod 422 to rotate, thereby realizing the lifting and lowering of the illumination lamp 3 through the rope 423, thereby adjusting the size of the illumination area and the intensity of the illumination.

[0027] In order to avoid the reduction of the light intensity of sunlight to the greenhouse. In this embodiment, see Figure 2 The top of the support frame 2 is vertically fixed with a spray frame 5. The spray frame 5 is a hollow structure and both sides of the top thereof are fixedly connected with a spray plate 6 facing the top side of the greenhouse body 1. The number and position of the spray plates 6 can be flexibly set according to actual conditions. The spray plate 6 is provided with a spray port at a position facing the top of the greenhouse. A fixed plate 7 is fixedly provided in the middle of the spray frame 5, and a blower 8 is fixedly provided on the fixed plate 7. The blower 8 is centrally controlled by a control module. The air outlet of the blower 8 is connected to the spray frame 5. The wind is generated by the blower 8 and sent to the inside of the spray frame 5. At this time, the wind blows toward the top side of the inside of the greenhouse through the spray plate 6, blowing off the water droplets that appear at the top of the inside of the greenhouse due to the temperature difference, avoiding excessive water droplets affecting the intensity of light, and enabling the water droplets to drive the dust to fall, so as to simply clean the inside of the greenhouse body 1 and enable the air circulation inside the greenhouse body 1.

[0028] The method of using the device for adjusting the internal light distribution of a greenhouse of the utility model is as follows: First, when the angle of sunlight changes due to seasonal reasons, resulting in a situation where some places inside the greenhouse are still not illuminated when the weather is clear. The photosensitive sensor arranged inside the greenhouse body 1 detects the area with insufficient light and feeds back a signal to the control module, and the control module controls the first bidirectional motor 413 in the corresponding area to work. The first bidirectional motor 413 drives the first screw 412 to rotate, so that the displacement frame 414 threadedly connected to the first screw 412 cooperates with the roller 415 to move on the support frame 2. In this process, the friction resistance is reduced by the roller 415, and the guide rod 411 plays a guiding role, thereby adjusting the position of the light lamp 3. When the position of the illumination lamp 3 is somewhat different from the position where supplementary light is required, the second bidirectional motor 419 can be controlled by the control module to work, and the second bidirectional motor 419 drives the second screw 418 to rotate, so that the lifting box 421 threadedly connected to the second screw 418 slides in the slide slot 417, and then the position of the illumination lamp 3 is finely adjusted, so that the illumination lamp 3 is located directly above the area to be supplemented with light to provide supplementary light for the area. At this time, the third bidirectional motor 425 can be controlled by the control module to work, and the third bidirectional motor 425 drives the rope reel 422 to rotate, so that the bottom plate 424 can be lifted and lowered through the rope 423, and then the illumination range and illumination intensity of the illumination lamp 3 can be changed. At the same time, the above operation can be controlled manually.

[0029] When the temperature difference between the inside and outside of the greenhouse body 1 is large, a large number of water droplets will adhere to the greenhouse body 1, and these water droplets will affect the intensity of sunlight exposure and the growth and development of plants inside the greenhouse body 1. At this time, the blower 8 can be controlled by the control module to work, and the blower 8 generates wind and sends it to the inside of the air spray frame 5. At this time, the wind blows toward the top side of the inside of the greenhouse through the air spray plate 6, blowing off the water droplets at the top of the inside of the greenhouse, avoiding excessive water droplets from affecting the intensity of light, and allowing the water droplets to drive dust to fall, so as to simply clean the inside of the greenhouse body 1 and allow air circulation inside the greenhouse body 1.
