High-efficiency and energy-saving solar greenhouses in alpine regions

Abstract

The invention relates to an energy-efficient solar greenhouse in an alpine region and is applicable to alpine regions with the temperature of 30 degrees below zero, and can be used for normally planting of vegetables and fruits without extra warming and heating to consume energy. The energy-efficient solar greenhouse is characterized in that turning heads and lower turning portions are arranged on a plurality of turning scaffolds, a plurality of eastward inclined planes and westward inclined planes, an automatic control system and an automatically collecting and putting heat preservation covering system are arranged on greenhouse films on the scaffolds. With the unique design of the turning scaffolds, absorption areas are enlarged on the basis of limited areas of the greenhouse films, lighting and heating efficiency is improved; angle of incidence is reduced when sunshine on the morning and in the afternoon shine obliquely, day lighting time is increased, the lighting and heating efficiency is further improved, limited solar energy is saved, lighting and warming efficiency is higher than that of common greenhouse, and production of the solar greenhouse in the alpine region can be increased; the energy-efficient solar greenhouse is scientific and reasonable in design, high in heat efficiency, heat-insulating and energy-saving; and operating cost of vegetable greenhouses is reduced and economic benefit is increased.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a high-efficiency and energy-saving solar greenhouse which can be used in high-cold regions around minus 30 degrees in winter and can normally produce vegetables and fruits without additional heating. Background technique [0002] The alpine region is cold in winter. In order to be able to engage in agricultural production in all seasons, improve land utilization, and to produce fresh vegetables and fruits all year round, some solar greenhouses or greenhouses have been developed over the years; but in the cold winter of about minus 30 degrees However, general solar greenhouses or greenhouses cannot guarantee the temperature required by vegetables and fruits, and heating facilities are still required for heating and energy consumption. Due to rising energy prices and labor input, the cost of producing fresh vegetables and fruits in alpine regions in winter has risen, making it difficult to ma...

AI Technical Summary

Problems solved by technology

Due to the rising price of energy and the input of labor, the cost of producing fresh vegetables and fruits in alpine regions in winter has increased, so that it is difficult to make ends meet; this is also the main reason why the prices of vegetables and fruits in the north remain high in winter

In addition, in winter in alpine regions, some farmers blindly introduce ordinary vegetable greenhouses. Due to the low temperature in winter, they cannot meet the requirements of vegetable growth temperature. In addition, the control of temperature regulation, humidity regulation and ventilation is also the key to ensure the increase of vegetables and fruits.
