Problems solved by technology

However, at present, some existing automatically inflatable life-saving equipment need to be manually activated to inflate the life-saving equipment when falling into the water for first aid, which is not applicable during the flight of the drone
Moreover, the existing inflatable life-saving equipment does not take sealing measures for the inflator during the inflation process, which reduces the efficiency of inflation.

Abstract

The invention provides a device capable of achieving automatic inflation when wet and an unmanned aerial vehicle provided with the device. The device comprises a valve body, an air source and a compression air bag, and further comprises a shell fixedly connected with the valve body and a puncturing mechanism arranged in the shell. The valve body is internally provided with an air channel, an air inlet and an air outlet of the air channel are connected with the air source and the compression air bag respectively, and a sealing film is arranged in the air channel or at the air outlet of the airsource. The puncturing mechanism comprises a striking pin, a pre-tightening elastic piece connected with the striking pin and a water-soluble limiting piece for limiting the displacement of the striking pin under the action of pre-tightening force, and a water seepage through hole is formed in the shell; the striking pin is opposite to the sealing film, and after the water-soluble limiting piece is dissolved, the striking pin punctures the sealing film under the action of the pre-tightening force of the pre-tightening elastic piece, so that the air channel is communicated with the air source.The water seepage through hole is formed in the shell, so that the compression air bag can be automatically inflated when the device is wet; meanwhile, the valve body can be sealed, so that the air iscompleted introduced into the compression air bag, and the utilization rate and inflation efficiency of air are improved.

Description

technical field [0001] The invention relates to the technical field of inflatable equipment. Background technique [0002] At present, the use of drones in aerial photography, agriculture, logistics, rescue and various engineering operations is becoming more and more mature. Correspondingly, the handling measures such as the failure and crash of drones in various complex situations are becoming more and more critical. The unavoidable path of drones in the application process includes water areas such as lakes and seas. At this time, if the drone fails, it may need to make a forced landing on the water. Conventional drones do not have water landing facilities, and if they fail to perform tasks on the water surface, they may fall directly into the bottom of the water, causing water pollution and making it difficult to salvage. In view of this, the UAV needs to have the function of forced landing on the water surface. [0003] At present, the measure taken by drones to adapt...
