Description
Technical Field
The utility model relates to a life saving equipment technical field, concretely relates to soft landing parachute of high building lifesaving.
Background
The parachute opening principle of the existing parachute is that relative high-speed airflow is generated by utilizing the speed of an object when the object descends rapidly and is filled into the parachute to open the parachute, and the parachute generates great air resistance after being opened, so that the running speed of the object is reduced, and the aim of reducing the speed is fulfilled. Therefore, the necessary condition for opening the parachute is that the object has sufficient speed of travel, i.e., sufficient descent height to generate a certain speed to ensure the parachute is fully opened. Therefore, the conventional parachute not only has a slow parachute opening speed because it needs to travel a considerable distance to open the parachute during the parachute opening process, but also must function under a condition of greater than a safe height. However, in the case of a fire in a high-rise building, for example, if a person trapped in the high-rise building opens the parachute during descent, a serious safety hazard may occur. In addition, even if the parachute is opened first and then jumps down, the height of the floor is limited, and certain impact can still be caused to the personnel at the time of landing, so that the personnel are injured.

Other technical features of the present embodiment are consistent with those of the present embodiment, and thus are not described in detail.
Example five:
fig. 7 shows a high-rise lifesaving soft landing parachute of the present embodiment, which comprises a parachute main body 50, a restraining device 30, a first air cushion 10 and a second air cushion 20, and further comprises a plurality of pulling ropes 40 connected between the restraining device 30 and the parachute main body 50.
The umbrella main body 50 includes a sail top 51 and a support portion 52 arranged on the sail top 51, and the support portion 52 is used for supporting the sail top 51. The leg portion 52 comprises a circumferential leg 521 and a plurality of diverging legs 522; along the perimeter support 521, along the edge of the sail top 51; a plurality of diverging legs 522 exit the center of the sail top 51 and are connected to respective predetermined connection locations along the perimeter legs 521.
The present embodiment is different from the first embodiment in that the bottom of the second air cushion 20 is provided with a third air port 25, and the third air port 25 is automatically opened when the bottom of the second air cushion 20 touches the ground (for example, the third air port 25 can only be opened in one direction, and when the bottom of the second air cushion 20 touches the ground, the air of the second air cushion 20 generates pressure to open the third air port 25). Preferably, a layer of cloth is laid on the bottom of the second cushion 20, and the third air port 25 is disposed above the layer of cloth.
Other technical features of the present embodiment are consistent with those of the present embodiment, and thus are not described in detail.
The utility model discloses a soft landing parachute of high building lifesaving, the stranded personnel of high building inflate for the support of parachute, first air cushion and second air cushion earlier, then jump down. Because the second air cushion and the first air cushion are arranged, when the parachute lands, the second air cushion, the communicating pipe and the first air cushion share the impact force from the ground, so that the impact force is greatly reduced when being transmitted to personnel. The air in the second air cushion is not required to be fully filled, so that the second air cushion cannot bounce to the air when touching the ground; and the sensing unit on the second air cushion can sense the impact force of the bottom surface, and when the control module judges that the impact force reaches a preset threshold value, the control module controls the second air hole to exhaust, so that the second air cushion is further prevented from rebounding, and the soft landing of the parachute is realized. In addition, because a plurality of communicating pipes are connected between the first air cushion and the second air cushion, the transmission of the impact force between the first air cushion and the second air cushion is greatly buffered when the parachute is in soft landing.
