Fire safety escape device for middle and primary school high-rise classroom

Abstract

The invention discloses a fire safety escape device for a middle and primary school high-rise classroom. The fire safety escape device is characterized by comprising an upper connecting rod, an elevation adjusting knob, a driving shaft, a driven shaft, a first gear, a second gear, a third gear, a fourth gear, a plate part, a hook part, a lower connecting rod, a motor, a speed reducer and a controlbox. When a fire disaster occurs, the fire safety escape device is hung on a window of the upper floor or an attic balcony, one end of a rope of the fire safety escape device is fixed to the drivingshaft and is wound clockwise, and the other end of the rope passes through the upper portion of the driven shaft and then is used for escape. After escape people and the rope are arranged, the controlbox controls the motor to work, the driving shaft is driven to rotate under the action of the speed reducer, and free falling is achieved. In the use process, control parameters can be input by a rescuer at the roof through a touch display screen and are used for controlling the motor, a rescuer on the ground can achieve communication with the control box in a wireless communication mode, and thefire safety escape device is suitable for building fire safety in multiple fields.

Description

technical field [0001] The invention relates to the field of building fire safety, in particular to a fire safety escape device for high-rise classrooms in primary and secondary schools. Background technique [0002] With the development of the world economy, there are many tall buildings in various cities. And accidents such as high-rise fires and explosions occur from time to time, and high-rise escape and self-rescue have become an urgent problem to be solved. In general multi-functional high-rise buildings, the internal passages are intricate. Once a fire breaks out, the vents in the building will quickly expand the fire and smoke, and will soon spread to every corner. Once covered by thick smoke, it will be difficult to move. Then he was trapped upstairs and couldn't get out. In order to solve this difficult problem, some relevant escape devices were conceived. [0003] However, when a sudden disaster strikes, usually the elevator cannot be used due to a power outage...

AI Technical Summary

Problems solved by technology

[0003] However, when a sudden disaster strikes, usually the elevator cannot be used due to a power outage, and the stairs are blocked by the crowd. The general ground rescue equipment may not be enough in height, and it will not be able to quickly and quickly because of the bulkiness of the equipment. The implementation of rescue, thus delaying the rescue time

[0004] Therefore, the escape device that can be raised and lowered just seems very important; Throughout the field of fire protection, although the existing auxiliary escape device is simple in structure, the rescue is relatively slow; it is often limited in actual use; in addition, the existing It takes a long time to erect and assemble the escape device, which will have a certain impact on the escape personnel's descent
