Greenhouse window automatically opening device

Abstract

The invention relates to window opening devices, particularly to a greenhouse window automatically opening device. The greenhouse window automatically opening device comprises a greenhouse and a window hinged to the window frame of the greenhouse; the wall of the greenhouse is horizontally provided with a through hole, inside which a connecting rod is slidingly connected, one end of the connectingrod outside the greenhouse is provided with a magnetic block, and the other end of the connecting rod inside the greenhouse is provided with a pressing plate; the inner wall of the greenhouse is provided with a mounting base, a rocker arm is hinged to the mounting base and composed of a driving end and a transmission end, a tension spring is connected between the driving end and the inner wall ofthe greenhouse, and the pressing plate can abut against the driving end when moving leftwards along with the connecting rod to drive the rocker arm to swing; the outer wall of the greenhouse, which is close to the through hole, is provided with an electromagnet capable of attracting the magnetic block, and the rocker arm can abut against the window during clockwise rotation. According to the greenhouse window automatically opening device, the electromagnet and the tension spring are matched to achieve swinging control of the rocker arm and further to control opening and closing of the window,thereby facilitating operation and saving time and labor.

Description

technical field [0001] The invention relates to a window opening device, in particular to an automatic window opening device 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 ...

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 opening and closing of the window.
