AI Technical Summary

Technical Problem

The existing greenhouse ventilation openings require manual opening and closing and cannot be automatically controlled. Furthermore, the airflow volume cannot be adjusted, resulting in high labor intensity and uncontrollable airflow content.

Method used

Temperature sensors are used to detect temperature changes inside the greenhouse. A motor-driven rack and pinion transmission system controls the rotation of the heat dissipation plates, enabling the automatic opening and closing of the ventilation openings. The airflow is also adjusted by the rotation of the heat dissipation plates, and a protective mechanism is used to prevent birds and insects from entering.

Benefits of technology

It enables automated control of greenhouse ventilation openings and adjustable airflow, reducing manual labor intensity, extending equipment lifespan, and ensuring airflow controllability.

Abstract

This utility model discloses a greenhouse control device that automatically opens and closes vents based on temperature, relating to the technical field of greenhouse control equipment. The device includes a temperature sensor installed on the inner side of the greenhouse wall, with vents on the surface of the wall. It also includes a ventilation mechanism and a protective mechanism. The ventilation mechanism is located on one side of the greenhouse wall and is used to automatically control and regulate airflow. The protective mechanism is located outside the ventilation mechanism and is used to prevent birds or insects from entering the greenhouse. The ventilation mechanism uses a motor to drive a second gear, rack, and first gear, which mesh to drive a heat sink plate to rotate, thus automatically opening and closing the vents without manual operation. The rotation of the heat sink plate adjusts its rotation angle, thereby regulating the direction and magnitude of airflow into the greenhouse. A temperature sensor detects temperature changes within the greenhouse, and a control module controls the motor's operation.
