Water body sunshade ball capable of reducing production cost

Abstract

The invention discloses a water body sunshade ball capable of reducing production cost. The sunshade ball comprises a hollow ball body, and the sunshade ball is mainly characterized in that the hollow ball body is designed to be a hollow oblate ball body, and a layer of reflection film is composited on the spherical surface of the hollow ball body; various knurling and embossing patterns are arranged on the surface of the reflection film. The sunshade balls are distributed on a water body in an even and dense mode, sunlight illumination is shielded, meanwhile, the effect of sun block of the water body can be remarkably improved, water evaporation is reduced, and the production cost can be reduced. The sunshade ball is applicable to water body sunscreen of a reservoir, a lake surface and a pond.

Description

Technical field [0001] The invention relates to the field of sun protection technology, in particular to a water sunshade ball capable of reducing production costs. It is suitable for sun protection in water bodies of reservoirs, lakes and ponds. Background technique [0002] Sunlight irradiates the water body to increase the temperature of the water body, which leads to a large amount of evaporation of water and a great loss of water resources. [0003] According to reports, in order to save water, Los Angeles, California, USA, put 96 million black plastic balls into the Los Angeles Reservoir to block sunlight and prevent water evaporation, which can save 300 million gallons of water loss every year. On the one hand, the black plastic ball can shield the sun, but because black absorbs the most heat of all colors, the black plastic ball absorbs a large amount of solar energy and transmits it to the water body, which is not conducive to effectively preventing the temperature rise o...

AI Technical Summary

Problems solved by technology

On the one hand, black plastic balls can shield sunlight, but because black absorbs the most heat among all colors, black plastic balls absorb a large amount of solar energy and transmit it to the water body, which is not conducive to effectively preventing the temperature rise of the water body, and affects to a certain extent The sun protection effect of the water body; on the other hand, the black plastic ball is set as a round ball, the surface area is small, and the production cost is high
