Embodiment Construction

[0020] Referring to the accompanying drawings, the solar greenhouse with variable inclination angle daylighting surface of the present invention includes a fixed solar greenhouse framework A and a movable solar greenhouse framework B. Among them, the fixed solar greenhouse frame A includes the fixed roof main roof truss member 15, the fixed roof front corner roof truss member 16 and the fixed roof truss rear slope member 14 connected together. Horizontal purlin members 18 are connected into one, fixed roof main roof truss members 15, fixed roof front corner roof truss members 16 select thin-walled rectangular steel pipes and connect them by welding, and fixed roof truss rear roof slope members 14 select rectangular steel pipes, which are connected with fixed roof trusses. The main roof truss members 15 are fixed together by bolts. In order to improve the overall rigidity of the fixed frame, horizontal support is provided for the drive shaft 9. After the roof truss is fixed, the...

Abstract

The invention discloses a sunlight greenhouse with a daylighting area with a changeable dip angle, comprising a surface fixed framework A and a surface movable framework B, wherein the surface fixed framework A is connected with the surface movable framework B though a connecting gear comprising a motor bracket arranged between a slope of roof component 14 behind a fixed frame of roof of the surface fixed framework A and a main frame of surface fixing element, and a gear motor is arranged on the motor bracket and is connected with a transmission shaft connected with a tightwire. Under the drive of the tightwire, the daylighting surface can adjust the own dip angle with different outside light conditions, thereby improving the lighting effect. Because of the particularity of the projection of lighting materials the change range of the dip angle fortunately makes the lighting surface angle shift from unfavorable conditions to the angle range of high projection rate, thereby greatly improving the lighting performance of the greenhouse. The sunlight greenhouse with a daylighting area with a changeable dip angle of the invention has the advantages of a reasonable structure, simple manufacture and manipulation and long service life.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse with a variable inclination angle lighting surface, the solar greenhouse can change the front lighting surface according to external lighting conditions, and can greatly improve the lighting performance of the solar greenhouse. Background technique [0002] At present, conventional solar greenhouses all use fixed roofs for lighting. Due to defects in architectural design, the lighting conditions in the solar greenhouse are poor. Although many researchers have invested a lot of time and energy in the study of the arc shape of the daylighting roof, due to the complexity and particularity of the daylighting problem, this research direction has not yet touched the key to improving the indoor lighting of the solar greenhouse. Moreover, a large number of studies have shown that under the same height difference range, the smaller the curvature of the greenhouse lighting surface, ...
