Problems solved by technology

[0004] The problem to be solved by the present invention is to reduce the light intensity in the solar greenhouse due to the decrease of the incident angle of sunlight in the northern solar greenhouse and to solve the shadow caused by the occlusion of the east and west walls in the greenhouse in the morning and evening.

Embodiment 1

[0016] Embodiment one: if figure 1 As shown, a solar greenhouse auxiliary light enhancement system includes side wall reflective curtains, and the side wall reflective curtains are hung on the east and west side walls of the solar greenhouse greenhouse; the rectangular upper frame is vertically arranged on the solar greenhouse. At the upper end of the north wall, a fixed shaft plate and a drive rod are also arranged in the rectangular upper frame; a rotating shaft is arranged at both ends of the lower frame body; shaft holes are drilled on the lower frame body, the fixed shaft plate and the drive rod; at least two Two reflectors, the two ends of the reflector have reflector shafts; the reflector shafts are fixed at the upper and lower ends of the reflector, and are respectively sleeved in the fixed shaft plate of the rectangular upper frame and the shaft hole of the lower frame; The shaft and the secondary shaft of the reflector are welded parallel to the shaft side of the ref...

Embodiment 2

[0017] Embodiment 2: In order to make the solar greenhouse auxiliary illumination enhancement system have a better reflective effect, on the basis of Embodiment 1, the reflective plate is made into a prism, and at least two surfaces of the prism are reflective surfaces. For example, the reflector is a triangular prism, and the two surfaces facing the sunlight are made into reflective surfaces.

Embodiment 3

[0018] Embodiment 3: The height and span of the greenhouse are determined according to the local latitude. Generally, for a greenhouse within the range of 30°-50° north latitude, the solar elevation angle is 0°-40°, and the lighting angle of the shed surface is 19° Within the range of °-32°, the effective height of the north wall is generally 2.5m-3.5m, and the span of the greenhouse is generally between 6m-10m. Such as figure 2 As shown, as shown, in order to make the light reflected at the top of the reflector just arrive at the front of the greenhouse, wherein:

[0019] sin(2α+β) / h=sin(90°-α-β) / 【b×sin(90°-α)】

[0020] Comprehensive solar greenhouse construction experience and material saving principles.

[0021] The angle at which the reflector is inclined (that is, the mirror inclination angle β in the illustration) is:

[0022] The tilting angle of the reflector is set from 0°-8°.

Abstract

The invention provides a solar greenhouse supplementary illumination reinforcing system.A side wall reflection curtain is hung on the eastern side wall and western side wall of a solar greenhouse, an upper rectangular frame is vertically arranged at the upper end of the northern wall of the solar greenhouse, and a fixed axle plate and a driving rod are arranged in the upper rectangular frame; rotary shafts are arranged at the two ends of a lower frame, axle holes are drilled in the fixed axle plate and the driving rod, and reflection plate shafts are arranged at the two ends of the reflection plate, fixed to the upper end and lower end of the reflection plate and located in the axle holes in the fixed axle plate of the upper rectangular frame and the lower frame in a sleeved mode respectively; counter shafts of the reflection plate are welded to the axial side of the reflection plate in parallel and located in the axle hole of the driving rod in a sleeved mode.By arranging the reflection plate scientifically and ingeniously, the problem that illumination intensity in the solar greenhouse is poor in the northern area due to the reduction of the solar incident angle is solved, and the problem that shadows are formed in the greenhouse in the morning and at night due to the blocking of the eastern wall and western wall is also solved.

Description

technical field [0001] The invention provides an auxiliary illumination enhancement system for a solar greenhouse. Background technique [0002] The design of the solar greenhouse in the northern region is usually a facility with three walls in the north, east and west, with a ridge height of more than 2m, a single-slope structure, and the heat source mainly depends on solar radiation. It has the characteristics of good thermal insulation performance, firm structure, good windproof performance, long service life, easy construction, and low investment. The height and span of the greenhouse are determined according to the local latitude, because the height and span determine the angle of the lighting surface of the greenhouse, and the angle of the lighting surface determines the incident angle of sunlight. To ensure that sunlight has a large incident rate, the incident angle should be less than 40°, because the transmittance of sunlight is closely related to the incident angl...
