Pressing the on button, the device is ready to turn on but does not start moving, for a total of three gears: the first gear device is pressed for fixing, and the apparatus can accommodate four people or so; when the second gear is pressed, the device moves upwards to the middle position to fix the device, and at the moment, although the bearing capacity of the device is reduced to some extent, the number of accommodated people is increased to about 8; and when the third gear is pressed, the device moves upwards until the device is completely opened and fixed, and the number of people is about 12. Finally, the stop button is pressed and the device returns to the initial position. The top support plate makes up the gap above the device and prevents the collapsed objects from entering the device from the gap above the device to cause injury to personnel. As for the survival problem of people waiting for rescue in the device, the device is provided with a survival rescue bag, and the bag stores the necessities such as food, water and the like necessary for the survival of people. After the device is started, the monitor detects that the device is started, and can make everywhere hiding people listen to the alarm to reach the position near the device along with the alarm sound, and rescue workers can find the position and search and rescue in time after the earthquake is finished, so that the survival rate of trapped people is greatly improved.

The application occasions of the technical scheme mainly comprise places with dense personnel, such as a large mall door, a park green space, a square, a stadium and the like. Can be applied to places which are difficult to avoid, such as schools, companies and the like according to the needs.

The technical scheme has the following advantages:

1. the novel umbrella type structure can be driven by the gear chain and fixed at different positions to adjust the opening and closing degree of the supporting structure according to the different numbers of people to be avoided.

2. The motor drives the gear chain transmission to enable the instrument to operate, and automation is convenient and fast.

3. When the instrument is not used, the supporting structure can be folded, and the space is saved to a certain extent.
