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

[0033] 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. Motor 8, each column is provided with the second motor 9 that is used to drive the second plane mirror to rotate, and the height of the annular bottom plate is higher than the...

Embodiment 2

[0043] Embodiment 2 comprises the structure and method part of embodiment 1, as figure 1 , figure 2As 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.

[0044] Also include the following steps:

[0045] 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, an...

Embodiment 3

[0047] Embodiment 3 comprises the structure and method part of embodiment 1, as figure 2 As shown, 16 third motors 13 are provided on the supporting base of the third embodiment, the rotating shafts of each third motor are respectively connected with each support rod, and each third motor is electrically connected with the controller.

[0048] If the current moment is within the interval [T3, T4], the controller controls each third motor to drive each support rod to rotate, controls each first motor to drive each first plane mirror to retract, and controls each second motor to drive each second plane mirror to form In the vertical state to the ground, control each lifting device to drive each concave lens down to the original state.

[0049] T3 is the sunset time of the day, and T4 is the sunrise time of the next day. In the interval [T3, T4], the controller controls each first plane mirror, second plane mirror and each concave lens to be retracted, thereby ensuring that each...

Abstract

The invention discloses an intelligent vegetable greenhouse and a method thereof, comprising an annular bottom plate, a plurality of arc-shaped support columns arranged on the annular bottom plate, a hemispherical light-transmitting shed arranged on each arc-shaped support column, and The support seat on the hemispherical light-transmitting canopy, the M support rods arranged on the support seat to extend obliquely outward and upward of the semicircular canopy and the first plane mirror arranged on each support rod; M≥4, close to There are M uprights on the ground of the annular bottom plate, and each upright is provided with a second plane mirror corresponding to the first plane mirror, and each support rod is provided with a first motor for driving the first plane mirror to rotate, and each Each column is provided with a second motor for driving the second plane mirror to rotate, and the height of the annular bottom plate is higher than that of the bottom of each column; 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...
