Problems solved by technology

The current solar greenhouse cannot be used due to the sunlight that irradiates the northern enclosure structure, and the solar energy utilization rate of the greenhouse per unit area is low, especially in winter, most of the sunlight cannot be irradiated on the plants; The loss of sunlight transmission, the intensity of sunlight received by plants is low, which affects the growth of some plants. For some plant cultivation that requires high sunlight intensity, artificial light sources are generally used to supplement it, resulting in higher energy consumption and cultivation costs. high
These problems limit and affect the further promotion and development of solar greenhouses

Abstract

The invention discloses a greenhouse with an adjustable light reflection device. The greenhouse comprises the adjustable light reflection device, a light-transmission layer, a heat preservation enclosing structure and a movable heat preservation quilt. The adjustable light reflection device is located in the greenhouse and close to the north face of the greenhouse. The movable heat preservation quilt is arranged on the light-transmission layer. The adjustable light reflection device comprises a plurality of reflector modules, a left supporting rod, a right supporting rod, a traction chain, driving gears and a motor cabinet. The reflector modules are parallelly placed in the vertical direction and connected with the traction chain through the gears. A motor in the motor cabinet drives the driving gears to rotate so as to adjust reflector angles. By adoption of the greenhouse, the solar energy utilization rate of the unit floor area is increased, meanwhile, the intensity of sunlight received by plants is improved, the heat preservation performance and the sunlight uniformity of the greenhouse are ensured, and the greenhouse is simple in structure, low in cost, attractive in appearance, and large in popularization potentiality.

Description

technical field [0001] The invention relates to a greenhouse, in particular to a greenhouse with an adjustable reflective device, and belongs to the technical field of solar energy utilization. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar water heaters have been successfully commercialized, and how to use solar energy more effectively has become the content of research by scientists from all over the world. [0003] Greenhouses can transmit light and keep warm, and are widely used to grow plants. In seasons that are not suitable for plant growth, the greenhouse can provide a growth period and increase production, and is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. [0004] The solar greenhouse is one of the important for...
