Problems solved by technology

[0003] However, strong light exposure is harmful to young plants. The good growth of plants requires regular light duration and reasonable light intensity. Plants are prone to wither due to excessive roasting and excessive transpiration. Generally, black shading nets are artificially laid. It is laid at noon when the light is most intense, and not laid at other times. The intensity of light is artificially controlled, and even if modern machinery is used to lay it automatically, the configuration of its background system requires strong technical means and requires more manpower and material resources. Initial investment

Embodiment 1

[0028] In the present invention, when the user uses the device, one side of the glass plate 1 with the outer arc-shaped concave surface 4 and the inner arc-shaped concave surface 5 faces the outdoor, and the side without the outer arc-shaped concave surface 4 and the inner arc-shaped concave surface 5 is opened. Facing the room, when sunlight irradiates on the surface of the glass plate 1 with high intensity, the outer curved concave surface 4 and the inner curved concave surface 5 cooperate with each other to form a convex lens structure, which can focus the light. The position of layer 7 is just at the focal point of the convex lens. The convex lens gathers the sun to heat up the mask layer 7. The convex lens is facing the memory metal strip. The memory metal is very sensitive to a specific temperature and will deform at a specific temperature. When the temperature of the memory metal strip rises, it will stretch out, and the whole mask layer 7 will be stretched out. When str...

Embodiment 2

[0031] Wherein, the inner surfaces of the two glass plates 1 close to the chute 8 are provided with inner arc-shaped concave surfaces 5 , and the outer surfaces of the two glass plates 1 opposite to the inner arc-shaped concave surfaces 5 are provided with outer arc-shaped concave surfaces 4 .

[0032]Both glass plates 1 are provided with an inner arc-shaped concave surface 5 and an outer arc-shaped concave surface 4, and the inner arc-shaped concave surface 5 and the outer arc-shaped concave surface 4 are all set on both sides of the chute 8. At noon in the daytime, the glass The convex lens on the outside of the board 1 gathers the sunlight, so that each mask layer 7 is unfolded to refract the sunlight part. At this time, the outdoor sunlight is sufficient or even too high due to the sun, and the shading film has a blocking effect on the light. , only part of the light can be projected, and when the glass plate 1 is observed from the outside, the glass plate 1 will appear as ...

Abstract

The invention discloses glass with the light intensity adjustable. The glass with the light intensity adjustable comprises two glass plates. A vacuum cavity is formed between the two glass plates. Multiple sliding grooves are symmetrically formed in the inner walls of two sides of the vacuum cavity. Shielding cover layers are slidingly connected to the sliding grooves. The shielding cover layers are spirally rolled inwards from the center. Limiting grooves are symmetrically formed in the inner walls of the other two sides of the vacuum cavity. An inner arc-shape concave surface is arranged inthe portion, close to the positions of the sliding grooves, in the inner surface of one of the glass plates. An outer arc-shape concave surface is arranged on the outer surface, opposite to the innerarc-shape concave surface, the glass plate. According to the glass with the light intensity adjustable, sensitivity of memory metal strips to the temperature is utilized, spirally rolled shielding cover layers are spread in a higher-temperature environment, a structure obstructing rays of light is formed, when illumination is too strong at high noon, part of rays of light are autonomously obstructed in time, then indoor seedlings are protected, and it is prevented that the indoor illuminated temperature is too high so that transpiration of plants is too big and cultivation of the plants is notbenefited.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a glass with adjustable light intensity. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) Yes, its main components are silicon dioxide and other oxides. Glass is very common in daily life. Most of the light transmittance of glass is a fixed value, and the light transmittance is generally high. The only way to reduce the light transmittance is to increase the light transmittance. When cultivating plant seedlings, plants need good light at all times, and are generally designed as glass rooms. [0003] However, strong light exposure is harmful to young plants. The good growth of plants requires regular light duration and reasonable light intensity. Plants are prone to wither due to excessive roasting a...
