Abstract

An automatic light-adjusting heat-collecting solar greenhouse based on temperature-regulating water pipes, including a temperature-regulating device. The temperature-regulating device includes M* A supporting structure of N fixing parts, the fixing parts are respectively used to fix the temperature adjustment unit; each temperature adjustment unit at least includes a light adjustment device and a temperature adjustment water pipe arranged at the lower end of the light adjustment device and at least partially extending along a longitudinal arc. The invention provides an automatic light-adjusting heat-collecting solar greenhouse, which stores light energy in the form of heat energy when the sun is sufficient, and uses the stored heat energy to heat the greenhouse when the temperature is low, so as to ensure that the plants in the greenhouse grow at a suitable temperature .

Description

technical field [0001] The invention relates to an automatic light-adjusting heat-collecting solar greenhouse based on a temperature-regulating water pipe, which belongs to the technical field of new energy. Background technique [0002] The notification number is CN202722148U, and China's implementation of the new patent discloses a reflective solar greenhouse. The reflective solar greenhouse is provided with an east-west greenhouse rear wall. One end of the steel scaffolding is erected on the back wall, the other end of the steel scaffolding is erected on the ground, the steel scaffolding is covered with a transparent greenhouse plastic cloth, and a rear wall in the solar greenhouse is provided with a A vertical picture frame, with multiple plane mirrors inlaid in the picture frame, each plane mirror can independently adjust the reflection angle, and a cloth curtain is arranged on the picture frame. Due to the large proportion of transparent covering plastic cloth in this...
