Description
Technical Field
The utility model relates to the technical field of high-altitude escape, in particular to a slowly-descending high-altitude escape device.
Background
With the development of economy, tall buildings have come throughout. When dangerous situations occur in a high building or high altitude, such as fire, earthquake and the like, people need to save oneself for escape or evacuation. Therefore, various high-altitude descent control devices are attracting attention from people in all areas.
The key of the high-altitude descent control device technology is slow descent, and a slow descent device capable of effectively generating a damping effect is required to achieve a slow descent effect. At present, the type of such devices at home and abroad is many, and as disclosed in Chinese patent application No. 116271587A, a descent control device comprises a fixed component and a rotating component, wherein the fixed component is provided with an annular fixed friction part, the rotating component comprises more than two valve parts, the more than two valve parts are jointly provided with an annular rotating friction part, and when a rope drives the rotating component to rotate through applying force, the valve parts are displaced towards a rotating center through applying force, so that the first friction surface and the second friction surface are contacted and rubbed. Under the action of more than two petals, stable friction resistance can be provided when a user descends so as to slow down the descending speed of the user.
However, the descent control device only depends on friction force as damping required by descent control, and when the descent control device is continuously used in a long stroke, the members are easy to overheat to cause thermal attenuation, so that damping is reduced or even fails, and a great potential safety hazard exists.

After the rope is unwound, the spring stretches, the two-way switch ascends under the action of the elasticity of the spring, the reversing circuit contact is connected, the rope winding shaft of the escape device is reversed, the rope is automatically retracted to be ready for next rescue, and the operation is repeated. The descent control device realizes the mutual switching between the forward connection and the reverse connection of the circuit by utilizing the mutual adjustment of the gravity of a human body and the elasticity of the spring, so that the direct current motor is rotated forward and backward, the evacuee stably descends when rescue is realized, and the safety rope is quickly retracted after the rescue is finished, so that the next rescue is prepared.
