The inflatable raft body 1 is provided with an inflatable air bag 1-1, and the air inlet end of the inflatable air bag 1-1 is connected with the air outlet end of an inflating device 7.

The length of the starting pull rope 3 can be 3 meters, and the starting pull rope 3 can control the time for starting the inflation of the inflation starting ring 2.

The inflatable raft body 1 may be formed of a conventional inflatable raft. The gas-filled activation ring 2 may be a conventional pull-ring type activation valve. The controllable release means 4 may be in the form of a remote clip of conventional technology.

The working principle of the embodiment is described below with reference to the accompanying drawings:

referring to fig. 1, in this embodiment, inflatable raft 1 is mounted on the bottom of aircraft 10 by using remote-controllable release hook 4 and mounting lifting rope 6, that is, remote-controllable release hook 4 is mounted on the bottom of aircraft 10, inflatable raft 1 is mounted on remote-controllable release hook 4 by mounting lifting rope 6, and the operator controls remote-controllable release hook 4 to release inflatable raft 1 by using a remote controller, so as to realize remote control. The liquid compressed gas or the reaction type gas generator is used as an air source for automatically inflating the inflatable raft body 1, the inflatable raft body 1 is controlled to inflate by a pull-type releasing mechanism (a starting pull rope 3 and a starting pull rope fastening lifting hook 5), and the rescue raft is controlled to inflate by a pull rope 3, one end of which is fastened at the bottom of the aircraft 10 and the other end of which is fastened on an inflation starting ring 2.

As can be seen from fig. 1, the top of the packed inflatable raft body 1 is connected with the mounting lifting rope 6, the mounting lifting rope 6 is locked to the controllable release lifting hook 4 when the rescue raft is loaded to the aircraft carrier, the locking and releasing states of the controllable release lifting hook 4 are controlled by the aircraft carrier in a remote manner, and the controllable release lifting hook 4 is fixed at the bottom of the aircraft carrier platform. Start stay cord and tie solid lifting hook 5 and fix in aircraft carrier platform bottom, will start the one end carry of stay cord 3 to start stay cord and tie solid lifting hook 5 when salvation raft loads, start the other one end of stay cord 3 and connect and aerify start ring 2. The inflation starting ring 2 is connected to an inflation starting device at the top of the liquid compressed gas or reaction type gas generator 7, and when the inflation starting ring 2 is pulled upwards for a certain distance, the inflation starting ring can be separated from the inflation starting device at the top of the liquid compressed gas or reaction type gas generator 7, and simultaneously the liquid compressed gas or reaction type gas generator 7 is triggered to start inflation action.

As can be seen from fig. 2-1 to 2-4, the inflatable raft 1 is put in as follows:

after the aircraft platform carries the inflatable raft body 1 to a rescue site (refer to fig. 2-1), an operator at an aircraft ground station or an aircraft driver operates a controllable release hook 4 in a remote control mode to throw the inflatable raft body 1 (refer to fig. 2-2), the pull rope 3 is started to be stretched and straightened gradually by curling along with the falling of the inflatable raft body 1, and when the pull rope 3 is pulled to be straightened, the inflatable start ring 2 (refer to fig. 2-3) is pulled, the inflatable raft body 1 starts to be automatically inflated and falls into water to be automatically unfolded (refer to fig. 2-4).

The aircraft platform can be composed of aircraft carriers such as a multi-axis unmanned aerial vehicle, a manned or unmanned helicopter, a manned or unmanned fixed wing aircraft, a gyroplane, a power paraglider, an airship and the like.

Application scenario 1: when flood disaster happens, the unmanned aerial vehicle carrier platform can carry the rescue raft to quickly approach 3-5 meters of people falling into water and hover 3-5 meters away from the ground to launch the rescue raft, and the rescue raft can be completely filled with the forming within 10 seconds from the time when the controllable release hook 4 is triggered to release. People falling into the water can choose to climb the raft or climb around the rescue raft to wait for subsequent rescue actions.

Application scenario 2: when a group marine accident happens, a plurality of rescue rafts can be carried by the unmanned aerial vehicle carrier platform for a single time to arrive above the accident site, multi-point rescue raft putting operation is carried out, and a single rescue raft can be used for 5 to 20 people to save self.

Application scenario 3: when personnel are confined by flood in a certain place, can carry the rescue raft that does not install the start-up stay cord by unmanned aerial vehicle carrier platform and support to trapped and put in near by the personnel of being trapped, trapped personnel can be in trapped place manual pull-out aerify start change 2 manual start-up aerify, the rescue raft is aerifyd and is accomplished the back, trapped personnel can sit in the rescue raft and hold the rescue raft and enclose the rope all around, when flood submergence trapped, trapped personnel drift downstream along with the rescue raft.

Specific example 2:

the specific embodiment of the utility model is characterized in that: the length of the start cord 3 may be 1 meter, 2 meters, 4 meters or 5 meters. The rest of the structure is the same as that of embodiment 1.

In summary, the present invention includes three parts: the rescue raft is accurately brought to a rescue place by the aircraft carrier, and then can be released by the aircraft carrier in a remote control mode to enable the rescue raft to be separated from the carrier, when the rescue raft is separated from the carrier within a certain range, the rescue raft is automatically started (by starting the length of the pull rope 3) to be inflated and molded and falls to the water surface, and people falling into the water can select to climb the raft or grasp the surrounding ropes of the rescue raft for self rescue to wait for follow-up rescue actions.

The utility model has the characteristics of simple structure, low cost, quick expansion, convenient carrying, short deployment time, accurate rescue and suitability for throwing various aircrafts, and is used for rescuing people in water disasters.
