Automatic opening and closing greenhouse with light thermal insulation material

Abstract

The invention discloses an automatic opening and closing greenhouse with a light thermal insulation material. The automatic opening and closing greenhouse comprises a main body frame. The main body frame comprises a movable frame body. The main body frame is provided with a thermal insulation layer and tracks. An external sensor is arranged on the exterior of the thermal insulation layer. The external sensor receives and transmits light signals to a PLC system, the PLC system further controls a drive system after receiving the signals, and by means of synchronous driving of a movement executing mechanism, the movable frame body moves through the tracks on the two sides. The automatic opening and closing greenhouse solves the problem that a modern greenhouse fixed structure does not have a convenient light receiving performance; the modern synchronous motor technology is adopted, bisynchronous driving is carried out, the external sensor is arranged on the exterior of the thermal insulation layer and controlled through luminance induction, automatic opening and closing states can be achieved according to illumination intensity, the thermal insulation layer can be automatically opened or automatically closed after a set value is reached, plants in the greenhouse can receive sunshine well even in winter, and true unmanned management is achieved.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, in particular, the invention relates to an automatic opening and closing greenhouse using light-weight thermal insulation materials. Background technique [0002] At present, vegetables grown in greenhouses have occupied the vast majority of the vegetable market and have been recognized by the market. However, the difficulties of greenhouse cultivation are also placed in front of the growers. That is, the length of light in the greenhouse and the insulation of the greenhouse cannot effectively guarantee the growth environment of the plants. In a more severe environment, they cannot meet the needs of the growth of plants in the greenhouse. Temperature, humidity, illuminance, CO 2 The concentration of the plant, the supply of nutrients for plant growth, the control of the ph value of the nutrient solution, the concentration control, etc. cannot be accurately controlled. At present, t...

AI Technical Summary

Problems solved by technology

The invention solves the problem that the fixed structure of the modern greenhouse does not have convenient light-receiving performance. The invention adopts modern synchronous motor technology, two-way synchronous drive, and precise stepping action, so that the automatic opening and closing of the greenhouse can pass through specific conditions. , through the action of the synchronous motor to drive the movable part of the shed body, to achieve the function of automatically opening half of the shed body

It solves the problem of large labor demand, and the insulation layer is made of foam material, which can effectively protect the temperature and humidity in the greenhouse. There is a sun room in the greenhouse with good light transmission, which can not only further ensure the temperature and humidity, but also give plants better Sunlight provides a better environment for plants to grow
