Problems solved by technology

[0004] During the daytime, vegetable greenhouses mainly rely on sunlight for lighting. Lighting is needed on cloudy days or at night. Although there is sunlight in the morning and evening, the sun’s altitude angle is too small and the intensity of solar radiation is low. It is difficult for the vegetables in the middle of the vegetable greenhouse to be exposed to sunlight. , still needs the supplement of light to meet the light demand of vegetable growth. Therefore, vegetable greenhouses need to consume a lot of electric energy

Embodiment 1

[0037] Such as figure 1 , figure 2 The illustrated embodiment is an intelligent vegetable greenhouse, which includes a circular base plate 1, 4 arc-shaped support columns 2 arranged on the circular base plate, and a hemispherical light-transmitting shed located on each arc-shaped support column. 3. The support seat 4 provided on the hemispherical light-transmitting canopy, the 16 support bars 5 extending obliquely outward and upward of the semicircular canopy on the support seat and the first plane mirror 6 provided on each support bar , there are 16 uprights on the ground near the circular bottom plate, each upright is provided with a second plane mirror 7 corresponding to the first plane mirror, and each support bar is provided with a first plane mirror 7 for driving the first plane mirror to rotate. The motor 8 is provided with a second motor 9 for driving the second plane mirror to rotate on each column, and the height of the annular bottom plate is higher than that of t...

Embodiment 2

[0048] Embodiment 2 comprises the structure and method part of embodiment 1, and embodiment 2 is as image 3 The lower side of the windshield facing the hemispherical light-transmitting canopy is provided with a flat mirror, and the upper side of the windshield facing the hemispherical light-transmitting canopy is provided with a concave mirror that is gradually curved toward the hemispherical light-transmitting canopy from bottom to top; The step windshield in embodiment 1 is replaced by:

[0049] The lower part of the windshield reflects light into the hemispherical light-transmitting canopy, and the upper part of the windshield converges and reflects the light into the hemispherical light-transmitting canopy.

Embodiment 3

[0051] Embodiment 3 comprises the structure and method part of embodiment 1, as figure 1 , figure 2 As shown, in embodiment 2, 16 lifting devices 11 are also provided on the ground close to the circular bottom plate, and each lifting device is provided with a concave lens 12, and each concave lens corresponds to each first plane mirror respectively, and each lifting device It is electrically connected with the controller, and the height of the lower part of each lifting device is lower than that of the circular bottom plate. The lifting device is a cylinder, the telescoping rod of the cylinder is connected with the concave lens, and each cylinder is electrically connected with the controller.

[0052] Also include the following steps:

[0053] Adjust the inclination angle of each concave lens on the light side of the hemispherical light-transmitting canopy, the controller controls each concave lens on the light-side of each hemispherical light-transmitting canopy to rise, a...

Abstract

The invention discloses an intelligent vegetable greenhouse and method. The intelligent vegetable greenhouse comprises a circular annular bottom plate, a plurality of curved support columns arranged on the circular annular bottom plate, a hemispherical transparent cover shed arranged on the curved support columns, a support base arranged on the hemispherical transparent cover shed, M support barsarranged on the support base and extending obliquely upward to the outer side of the hemispherical cover shed, and a first plane mirror disposed on each support bar; M is larger than or equal to 4, Mvertical columns are arranged on the ground close to the circular annular bottom plate, and each vertical column is provided with a second plane mirror corresponding to one corresponding first plane mirror; and groove are arranged in the ground and at left and right sides of the circular annular bottom plate, and a windshield is arranged in each groove. The greenhouse and method disclosed by the invention has the characteristics of high sunlight utilization efficiency and effective energy saving.

Description

technical field [0001] The invention relates to the technical field of vegetable production equipment, in particular to an intelligent vegetable greenhouse and method with high sunlight utilization efficiency and effective energy saving. Background technique [0002] The solar altitude angle refers to the angle between the incident direction of sunlight and the ground plane. When the solar altitude angle is 90°, the solar radiation intensity is the largest; when the sun obliquely hits the ground, the solar radiation intensity is small. [0003] The sun altitude angle is referred to as the sun altitude (actually angle), the sun altitude is the most important factor determining the amount of solar heat energy obtained by the earth's surface, and the sun altitude angle is constantly changing within a day at the same place. For example, the solar altitude angle at 12 noon is 90 degrees, and it changes by 15 degrees every hour, that is, the solar altitude angles at 14 o'clock and...
