Independent adjusting device and method for light source height of multi-layer plant culture shelf

Abstract

The invention relates to an independent adjusting device for light source height of a multi-layer plant culture shelf. The device comprises a vertical frame; a plurality of layers of bearing shelves are fixed at intervals in the vertical frame from top to bottom at intervals; a main light board is arranged above any one of the bearing shelves; each main light board is glidingly matched with a guide chute which is vertically formed in the circumferential side of each main light board; a driven rotating shat passes through the center of each main light board; each driven rotating shaft is correspondingly connected with a transmission wheel assembly; a first driving rotating shaft and a second driving rotating shaft are vertically arranged in the vertical frame; a switching arm set which sleeves the first driving rotating shaft is in rotating fitting with a connecting part set which sleeves the second driving rotating shaft; one connecting part is connected with each transmission wheel assembly to drive the corresponding driven rotating shaft to rotate, and other connecting parts are idle. The invention further relates to an adjusting method of the independent adjusting device for the light source height of the multi-layer plant culture shelf. With the adoption of the device and the method, the main light boards at different shelf layers can be independently adjusted; the flexibility is high; the adaptability is high.

Description

technical field [0001] The invention relates to an independent adjustment device and an adjustment method for the height of a light source for a multi-layer plant cultivation frame. Background technique [0002] Light is not only the energy source for plant photosynthesis, but also one of the most critical environmental factors affecting plant growth. The mechanism of the effect of light environment on plant growth is very complex, and it needs long-term and in-depth research to be further clarified. Natural light sources are difficult to provide an ideal research environment due to constraints such as geographical location, seasons, weather, and time. Plant cultivation racks can be fully used The use of artificial light sources to create an adjustable light environment for plant growth provides favorable conditions for the study of the mechanism of light environment on plant growth. [0003] In traditional plant cultivation racks, the installation height of the artificial ...

Problems solved by technology

Since the illuminance of artificial light sources conforms to the inverse square law, that is, the farther away from the light source, the smaller the illuminance, and because of the difference in height between different plants or the same plant in different growth stages, the illuminance obtained by plants is different, so Greatly reduces the versatility of plant cultivation racks; especially for multi-layer plant cultivation racks, traditional plant cultivation racks are difficult to independently adjust the height of the plant light source on any one of the racks, and the applicability is poor
