Large-area shading device of tea gardens based on photovoltaic panel power generation

Abstract

The invention discloses a large-area shading device of tea gardens based on photovoltaic panel power generation. The device comprises a plurality of vertical supports. Solar power photovoltaic panels are arranged on the top of the vertical supports, and the lower ends of the vertical supports are provided with water collection channels. A drive cable is surrounded on a reversing wheel located at two sides. Drive shafts are arranged on the vertical supports, and reel sleeves are arranged on the drive shafts. Sunshade nets are arranged between the adjacent vertical supports. The right end of the sunshade nets is connected to the upper part of the corresponding vertical support; the left end is connected to sliding bars. The sliding bars are fixed on the cable through the respective pulling rod in a clamped mode. Curtain-supporting lines are arranged below the sunshade nets, and curtain-pressing lines are arranged on the sunshade nets. Clips of the middle part of positioning guide clips are arranged on the sliding bars in a clamping mode; holes in the upper part are arranged on the curtain-pressing lines in a penetrating mode and holes in the lower part are arranged on the curtain-supporting lines in a penetrating mode. The device has the advantages of being suitable for large-area use, flexible and quick in deploying and retracting, using sun to generate electricity effectively, and collecting rainwater for tea garden irrigation.

Description

technical field [0001] The invention relates to a shading device for tea trees, in particular to a large-area shading device for tea gardens based on photovoltaic panels for power generation. Background technique [0002] Tea tree is a kind of perennial evergreen shade-tolerant woody plant that likes light but cannot be overly illuminated. The artificial cultivation of tea tree in my country has a history of thousands of years, and there are currently tens of millions of acres of tea gardens. Aiming at the microclimate control technology and facilities of tea gardens, many domestic research institutions have conducted research on the correlation between tea garden shading and tea yield and quality. The results showed that reasonable shading could promote early germination of tea shoots, increase bud weight and fresh leaf yield, reduce the content of tea polyphenols, increase the content of amino acids and caffeine, and improve the quality of tea. Aiming at the characteristi...

Problems solved by technology

However, in the prior art, because the sunshade net adopts a reel retractable structure, if the sunshade net is longer, it will be very difficult and time-consuming to take up the sunshade net by the reel. After rolling up, the diameter will be very thick, the weight will be heavy, and the cost will be higher; In addition, the sunlight blocked by the shade net in the tea garden has not been effectively utilized, and rainwater cannot be collected for tea garden irrigation
