Problems solved by technology
[0004] In order to solve the problem of unsatisfactory supplementary light from artificial light sources in greenhouses and weak light syndrome in off-season greenhouse crops, the present invention provides a natural sunlight supplementary light system, which can automatically supplement light according to the environmental conditions in the shed, and can also be used according to different conditions. According to the needs of crops, artificial "lighting and catering" is carried out according to the physiological laws of plants to achieve the best growth needs of this crop

Embodiment Construction
[0016] see figure 1 , the present invention mainly consists of three parts, a greenhouse device, an optical fiber system device and a micro-spray device. Mainly include: 1. Solar concentrator, 2. Concentrating lens, 3. Conical reflector, 4. Optical fiber receiver, 5. Concentrator bracket, 6. Light guide fiber, 7. Greenhouse, 8. Vegetables Planting scaffolds for crops, 9. Vegetable plants, 10. Ventilation windows, 11. Optical fiber splitter, 12. Reservoir, 13. Micro-jet pump, 14. Water pipe, 15. Micro-jet nozzle, 16. Access door. During implementation, at first the solar concentrator 1 is installed on the outside of the greenhouse 7, and the angle between the solar concentrator and the concentrator support 5 is adjusted so that the upper port of the solar concentrator 1 is facing the sunlight, and the sunlight passes through the concentrator. The converging of the lens 2 and the reflection of the tapered reflector 3 make the bundle of sunlight converge on the optical fiber rec...

A greenhouse light-supplementing device based on concentrating solar optical fibers includes: a greenhouse, vegetable plants, a water micro-spraying device, a solar concentrator, a light-guiding optical fiber, an optical fiber receiver, and an optical fiber splitter. It is characterized in that the solar concentrator is placed outside the greenhouse, the high-intensity sunlight gathered by the solar concentrator is received by the optical fiber receiver, and the high-intensity sunlight is guided into the light-guiding optical fiber, and through the flexible transmission of the light-guiding optical fiber, the The beam of high-intensity sunlight is sent to the optical fiber splitter in the greenhouse, and the optical fiber splitter sends out the sunlight directly according to the needs to supplement the light for the plants in the greenhouse. When the humidity in the greenhouse is insufficient, the moisture micro-nozzle Spray water to irrigate crops to ensure the moisture needed for crop growth.
Description
technical field [0001] The invention belongs to a greenhouse light supplement device, in particular to a greenhouse greenhouse light supplement device based on concentrating solar optical fibers. Background technique [0002] Greenhouses have been popularized in a large area in my country, and the development of greenhouse vegetables is an important means of building resource-saving and environment-friendly agriculture. The shortage of agricultural resources and the deterioration of the production environment are the bottlenecks restricting the development of agriculture. The development of greenhouse vegetables can significantly reduce the area of cultivated land, reduce the use of water resources, chemicals, and energy consumption per unit of output, and comprehensively increase the use of agricultural production. Efficiency, to achieve environmental friendliness and resource conservation in agricultural production. Greenhouse vegetables make full use of the natural env...
