Active daylighting and solidified soil independent heat storage rear wall sunlight greenhouse

Abstract

The invention discloses an active daylighting and solidified soil independent heat storage rear wall sunlight greenhouse which comprises a front wall, a rear wall and a roof. The roof is composed of a movable framework and a fixed framework, the movable framework and the fixed framework are fixed between the front wall and the rear wall, the movable framework is connected with one end of the fixed framework through a rotating bearing, the movable framework is connected with the other end of the fixed framework through a transmission system composed of a speed reduction motor, a transmission shaft, a gear and a rack, the internal structure of the rear wall comprises a solid bricking wall, the solid bricking wall is filled with a solidified soil heat storage layer, and an outer wall insulation board is arranged on the outer portion of the solid bricking wall. The external structure of the rear wall comprises a rear wall bricking body, an active heat storage prefabricated pore channel floor slab, a top reinforced concrete sealing plate and a back slope, wherein the back slope is arranged above the top reinforced concrete sealing plate, a concrete outer layer on the back slope extends in the fixed framework direction to form a slope top, and the active heat storage prefabricated pore channel floor slab is communicated with the interior of the sunlight greenhouse through an axial flow fan installed in an opening portion. The automation level of the greenhouse can be greatly improved.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse with active lighting and heat storage. The solar greenhouse can actively change the lighting angle of the front lighting surface according to the external lighting conditions, and at the same time can actively use fans to send a large amount of light to the rear wall of the greenhouse. Heat storage, and because the rear wall adopts a large number of solidified soil masonry technology, it can fundamentally improve the lighting and heat storage performance of the solar greenhouse on the basis of reducing the construction cost of the greenhouse soil. Background technique [0002] At present, conventional solar greenhouses use fixed daylighting roofs and passive heat storage rear walls. Due to architectural design defects, the lighting conditions in solar greenhouses are not only poor, but also difficult to improve. In recent years, although many researchers have invested a lo...

Problems solved by technology

Therefore, changing the curvature of the lighting surface of the greenhouse cannot fundamentally solve various problems such as insufficient lighting and insulation difficulties in the solar greenhouse.

[0003] In addition, in terms of heat storage in solar greenhouses, conventional solar greenhouses use passive heat storage, resulting in a serious shortage of heat storage in the greenhouse. The back wall is getting thicker and thicker, and the cost is gradually rising, but at the same time, the heat storage performance of the greenhouse has not improved much.

Although many researchers have devoted a lot of time and energy to the study of heat storage in the back wall, due to the complexity and particularity of the heat storage problem in the back wall, this research direction has not touched the key to improving the thermal insulation performance of solar greenhouses.
