A ventilation window with multiple blades interlaced along the driving rod

Abstract

A ventilation window with multiple blades arranged along a drive rod in a staggered mode comprises a window body, a motor and a controller. A movable port is formed in the middle of thick glass arranged in the middle of the window body, and a rotating shaft and the blades connected to the rotating shaft are arranged inside the movable port. A circle with the distance from the peaks of the edge of each blade to the corresponding center portion as the radius and with the center portion as the centers is tangent to a plane where brown paper is located, the plane where the brown paper is located is parallel to blade surfaces of the blades, and one end of the rotating shaft is connected with the drive end of the motor. The controller comprises an outer metal shell, an inner metal shell, an input power line, an outer power line, an n-shaped insulating plate and an input paraffin block. An input conductive sheet connected to the input power line and an output conductive sheet connected to the output power line are arranged inside the inner metal shell in the manner that the input conductive sheet right faces the output conductive sheet. The ventilation window can automatically vent air during fire disasters, reduces fire loss conveniently, and is simple in structure, high in practicability and low in cost.

Description

technical field [0001] The invention relates to a fire prevention device, in particular to a ventilation window with multiple blades arranged staggered along the driving rod, which is particularly suitable for automatically exhausting air through the window in case of fire to reduce fire losses, and has simple structure, strong practicability, Advantages of lower cost. Background technique [0002] At present, the windows sold on the market and used in daily life are all manually opened, and the windows cannot be opened automatically according to the changes in the environment outside the window itself to achieve automatic ventilation, which is very inconvenient, especially when a fire occurs indoors, if the window can At this time, the automatic exhaust is not only beneficial to reduce the indoor temperature, but also helps to discharge the smoke caused by the indoor fire, which is very beneficial to reduce the loss of the fire. [0003] Chinese patent, the authorized anno...
