[0002] A greenhouse is a man-made structure that is usually used to grow crops or cultivate plants, providing a good growth environment and protecting plants from adverse external environmental influences. The introduction of carbon dioxide into the greenhouse is mainly used to enhance plant growth. Carbon dioxide is a key raw material for plant photosynthesis. By increasing the concentration of carbon dioxide in the greenhouse, plant growth and yield can be promoted.

The pipes are connected to carbon dioxide supply equipment, and carbon dioxide is continuously supplied to the greenhouses through the supply equipment. For the pipeline supply method, there is a problem of uneven distribution of carbon dioxide. Too high or too low carbon dioxide concentration will harm the growth of plants, and too high carbon dioxide concentration will also harm the health of workers. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] like Figure 1-4 As shown, the technical solution of the utility model provides a greenhouse carbon dioxide air intake device, including an air intake component 1 2, an air intake component 2 3, an air intake component 3 4 and an air equalization component 5 driven by the air intake component 1 2 and the air intake component 2 3, which are arranged on the greenhouse body 1. The air intake component 3 4 and the air equalization component 5 are both located between the air intake component 1 2 and the air intake component 2 3; the air equalization component 5 includes a mounting frame 9 and an air equalization disk 10 rotatably arranged on the mounting frame 9, and the air outlets of the air intake component 1 2 and the air intake component 2 3 are respectively arranged on both sides of the air equalization disk 10, and are arranged in a staggered manner.

[0022] Air intake assembly 1 2, air intake assembly 2 3 and air intake assembly 3 4 all introduce carbon dioxide into the greenhouse, wherein the carbon dioxide introduced by air intake assembly 1 2 and then assembly 2 has pressure, during the introduction process, the gas hits the uniform gas plate 10, because air intake assembly 1 2 and air intake assembly 2 3 are arranged oppositely and staggered, the uniform gas plate 10 will rotate under the action of the airflow, disturbing the airflow during the rotation process, achieving the dispersion of carbon dioxide, and avoiding the local carbon dioxide concentration being too high or too low. The carbon dioxide concentration in the greenhouse is monitored by sensor 17.

[0023] The gas-distributing plate 10 is arranged horizontally, and the mounting frame 9 is fixed to the greenhouse body 1. The gas-distributing plate 10 includes a plurality of gas-distributing plates 11 arranged at intervals, and the gas-distributing plates 11 are hollow plastic plates. The gas discharged from the air inlet assembly 1 2 and the air inlet assembly 2 3 acts on the gas-distributing plates 11, which are made of plastic and have a hollow structure, are light in weight, and are easy to rotate.

[0024] The air intake assembly 1-2 and the air intake assembly 2-3 both include an air intake main pipe 1-6 and an air intake branch pipe 1-7 arranged on the air intake main pipe 1-6, and the air intake branch pipe 1-7 is arranged horizontally and toward the air equalizing plate. The air outlet end of the air intake main pipe 1-6 is longitudinally provided with a strip-shaped air outlet 8, and the strip-shaped air outlet 8 is arranged close to the air equalizing plate 10. The air intake branch pipe 1-6 of the air intake assembly 1-2 is opposite to the air intake branch pipe 1-6 of the air intake assembly 2-3 and is arranged in a staggered manner.

[0025] In the above scheme, the carbon dioxide gas enters the air intake branch pipe 7 from the air intake main pipe 6, and then is discharged from the strip outlet 8. Because the opening of the strip outlet 8 is small, the air flow has a strong pressure after being gathered, and the strip opening can better drive the air homogenizing plate 11 to rotate. The air intake branch pipe 7 arranged on both sides increases the rotation speed of the air homogenizing plate 11 and achieves a better dispersion effect.

[0026] The air intake assembly 3 4 includes an air intake main pipe 2 12 and an air intake branch pipe 2 13 which are connected in sequence. The air intake branch pipe 2 13 includes a vertical portion 14 and a horizontal portion 15. The horizontal portion 15 is connected to the vertical portion 14 and extends to both sides. The horizontal portion 15 is evenly distributed with air outlet holes 16. The horizontal portion 15 is extended to preliminarily disperse carbon dioxide. The horizontal portion 15 with the air outlet holes 16 is located below the gas-distributing disk 10. Because the air outlet holes 16 distributed on the horizontal portion 15 have a relatively small pressure after discharge, the rotation of the gas-distributing disk 10 will not be affected. At the same time, when the gas-distributing disk 10 rotates, the gas discharged from the horizontal portion 15 can also be dispersed.

[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
