Greenhouse window automatically opening system

Abstract

The invention relates to window opening systems, particularly to a greenhouse window automatically opening system. The greenhouse window automatically opening system comprises a window hinged to a window frame and is characterized by also comprising a mounting base which is fixed onto the inner wall of a greenhouse and close to the window, and a rocker arm for driving the window to open and close;the rocker arm comprises a driving end and a transmission end, the middle of the rocker arm is hinged to the mounting base, the transmission end of the rocker arm abuts against the window, the rightof the driving end of the rocker arm is provided with a magnetic block, the left of the rocker arm is provided with a tension spring, both ends of the tension spring are connected to the inner wall ofthe greenhouse and the driving end respectively, the inner wall of the greenhouse is provided with an L-shaped mounting rack above the mounting base, and the vertical section of the L-shaped mountingrack is provided with an electromagnet magnetically matched with the magnetic block. According to the greenhouse window automatically opening system, the electromagnet and the tension spring are matched to drive the rocker arm and further to control opening and closing of the window, so that the greenhouse window automatically opening system has the advantages of being high in automation degree and is convenient to operate and saves time and labor.

Description

technical field [0001] The invention relates to a window opening system, in particular to an automatic window opening system for a greenhouse. Background technique [0002] Greenhouse, that is, greenhouse, is a facility used to cultivate plants. Because of its light transmission and heat preservation, it is mostly used for the cultivation or seedling cultivation of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. [0003] The greenhouse structure should be sealed and insulated, but it should be convenient for ventilation and cooling. In the existing greenhouses, the opening and closing of the windows is often manually operated, and they are opened or closed one by one. For larger greenhouses, the number of windows is relatively large, and it will cost more manpower, material resources and resources to open and close the windows. Time is sometimes limited by the height of the window, which brings a lot of inconvenience to the ...
