Description

Technical Field

[0001] This utility model relates to the field of flower planting greenhouses, and in particular to a flower planting greenhouse with automatic light adjustment. Background Technology

[0002] Flowers generally receive sunlight during their growth. When sunlight is weak, supplemental lighting is used to increase light intensity, thus ensuring normal growth. Furthermore, to promote flowering and growth, flowers can be alternately exposed to blue and red light. Currently, the main method of supplemental lighting involves adding red and blue supplemental lights to the greenhouse, along with transparent light, requiring at least three sets of bulbs of different colors. This increases the power consumption of supplemental lighting, the cost of equipment installation, and the greenhouse space occupied, thereby increasing farmers' production costs. Utility Model Content

[0003] The purpose of this application is to provide a flower cultivation greenhouse with automatic light regulation, which aims to solve the problems existing in the prior art.

[0004] This application provides a flower planting greenhouse with automatic light adjustment. The greenhouse is equipped with a roof frame, and parallel beams are fixed inside the roof frame. The beams divide the interior of the roof frame into multiple skylight zones, and supplementary lights are fixed below the beams.

[0005] A bottom beam is fixed to the column below the top frame. A take-up shaft driven by a traction motor is set at one long end of the bottom beam. A traction cable is wound on the take-up shaft, and the other end of the traction cable is fixedly connected to a traction block. The traction block slides horizontally along the bottom beam. A traction head is connected to the traction block. The traction head is fixed to one end of the color filter membrane, and the other end of the color filter membrane is wound on a return roller shaft. The return roller shaft is installed at the other long end of the bottom beam, and a return roller motor is drivenly connected to the return roller shaft.

[0006] Furthermore, the upper surface of the traction block is provided with a suction area, and a suction device is installed on the traction head. The suction device is used to suction the traction head onto the traction block to fix the traction head and the traction block together.

[0007] Furthermore, the suction device is an electromagnetic chuck, and the suction area is equipped with a metal layer that can be attracted by an electromagnet; or the suction device is a vacuum chuck.

[0008] Furthermore, the pull block has a stepped shape with a higher front and a lower back. The higher step of the pull block corresponds to the upper pull head, and the color filter membrane connected to the upper pull head is wound on the upper return roller and driven by the upper return roller motor. The lower step of the pull block corresponds to the lower pull head, and the color filter membrane connected to the lower pull head is wound on the lower return roller and driven by the lower return roller motor. The height of the upper surface of the lower pull head is lower than the height of the lower surface of the upper pull head.

[0009] Furthermore, the colors of the upper and lower color filters are blue and red, respectively.

[0010] Furthermore, the greenhouse is equipped with light sensors and color sensors.

[0011] The beneficial effects of this invention are as follows: This invention uses a traction motor and a rewind motor to spread a single-color filter film in the greenhouse. Replacing the use of various colored supplemental lighting lamps with this method significantly reduces energy consumption. The use of a single-color transparent plastic material for the filter film helps control costs. Furthermore, the combined installation of a light sensor and a color sensor enables automatic control of light intensity and color adjustment. Attached Figure Description

[0019] 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.

[0020] like Figures 1-5 The diagram shows an automatically adjustable light-regulating flower cultivation greenhouse. The greenhouse roof is equipped with a roof frame 1, as shown in the diagram. Figure 1The structure is rectangular. A beam 2 is fixed inside the top frame 1, parallel to its long side. There can be one or more beams 2. The beams 2 divide the interior of the top frame 1 into multiple skylight zones 3, through which sunlight can reach the interior of the greenhouse. Transparent glass can be installed in the skylight zones 3 to enclose the greenhouse roof. Supplemental lighting 4 is fixed below the beams 2.

[0021] like Figure 2 As shown, a bottom beam 5 is fixed to the column 13 below the top frame 1. The bottom beam 5 is spaced apart from the top frame 1 and is parallel to the long side of the top frame 1. A take-up shaft 7 driven by a traction motor 6 is installed at one long end of the bottom beam 5. Figure 3 As shown, a traction cable 8 is wound on the take-up shaft 7, and the other end of the traction cable 8 is fixedly connected to the pull block 9. A slider 10 is provided on the side of the pull block 9, and a groove 11 with a shape that matches the slider 10 is opened on the inner side of the bottom beam 5, so that the pull block 9 can slide horizontally along the bottom beam 5. The traction motor 6 can drive the take-up shaft 7 to rotate, so that the traction cable 8 is wound on the take-up shaft 7, thereby pulling the pull block 9 to move in the direction of the take-up shaft 7.

[0022] A puller head is connected to the pull block 9 via a suction device 12. The puller head is fixed to one end of the color filter film 14, and the other end of the color filter film 14 is wound around a return roller. The return roller is installed at the other end of the bottom beam 5, and a return roller motor is driven to the return roller. When the pull block 9 moves towards the take-up shaft 7, it pulls the color filter film 14 to unwrap it from the return roller, thus unfolding the color filter film 14. When sunlight or supplemental light shines downwards, it passes through the color filter film 14, thus emitting monochromatic light that promotes flower growth and flowering. When filtering is not needed, the return roller motor drives the return roller to reverse, winding up the color filter film 14, thereby pulling the pull block 9 towards the return roller.

[0023] Pull block 9 as Figure 3 and Figure 4 The device is shown in a stepped shape, higher at the front and lower at the back. The higher step of the pull block 9 corresponds to the upper pull head 16, and the color filter membrane 14 connected to the upper pull head 16 is wound on the upper return roller 17 and driven by the upper return roller motor 18. The lower step of the pull block 9 corresponds to the lower pull head 19, and the color filter membrane 14 connected to the lower pull head 19 is wound on the lower return roller 20 and driven by the lower return roller motor 21. The upper surface of the lower pull head 19 is lower than the lower surface of the upper pull head 16. The two pull heads pull different colored color filters 14 respectively. By energizing the suction devices 12 on the two pull heads, different colored color filters 14 can be selectively pulled. The colors of the two color filters 14 are blue and red, respectively, thus allowing different monochromatic lights to be irradiated according to different growth requirements. The stepped shape of the pull block 9 ensures that the pulling of different pull heads is independent and unaffected.

[0024] Both the upper traction head 16 and the lower traction head 19 on the bottom beam 5 are provided with stop blocks (not shown in the figure). The stop blocks are used to block the traction head from rolling back, prevent the traction head from rolling back too much, and provide the initial position for the traction head to be pulled by the traction block 9.

[0025] like Figure 3 and Figure 5 As shown, the upper surface of the pull block 9 is provided with a suction area 15, and a suction device 12 is installed on the pull head. The suction device 12 attracts the pull head to the pull block 9, thus fixing the pull head and the pull block 9 together. The suction device 12 is an electromagnetic chuck, and the suction area 15 is equipped with a metal layer that can be attracted by an electromagnet; or the suction device 12 is a vacuum chuck. When the suction device 12 is energized, it can be activated to generate magnetic force or vacuum negative pressure to bond the pull head to the pull block 9.

[0026] The greenhouse is equipped with light and color sensors. The light sensor detects light intensity to determine the time of day; when light intensity decreases, supplemental lighting (4) can be activated to increase it. The color sensor detects the color reflected from a color chart to determine the status of the color filter (14). After receiving signals from the light and color sensors, the controller sends commands to the supplemental lighting (4), traction motor (6), and return motor, thereby achieving automatic control of supplemental lighting, sunlight reception, and switching to monochromatic light modes within the greenhouse.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
