Detailed Description
The invention is further described below with reference to the drawings and examples.
FIG. 1 is a schematic diagram of a man-water-in-water indication mark with an air bag floating antenna according to the present invention when not activated; fig. 2 is a schematic diagram of a man-water-falling indication mark with an air bag floating antenna according to the present invention after being started.
Referring to fig. 1 and 2, the personnel water falling indication mark with the air bag floating antenna provided by the invention comprises a water falling indication mark 7, wherein the water falling indication mark 7 is connected with an antenna 6 through an antenna feeder line 1, the antenna 6 is arranged in an air bag 2, an inflation inlet of the air bag 2 is connected with an inflation tank 5 through a flexible inflation tube 3, and a switch release device 4 is arranged at the joint of the flexible inflation tube 3 and the inflation tank 5.
The personnel water falling indication mark with the air bag floating antenna is characterized in that an air bag 2 and a small-sized air charging tank 5 with high-pressure light gas inside are additionally arranged on the basis of the original personnel water falling indication mark 7, and the air charging tank 5 is made of light metal materials.
The control process of the personnel water falling indication position mark with the air bag floating antenna is as follows: when the position indicator is not started, the antenna 6 is regularly arranged in the air bag 2, the air bag is integrally folded and then is arranged at the top of the position indicator, the inflation tank 5 and the inflation control switch releasing device 4 are fixed at the middle and lower positions of the position indicator, and the air bag is connected with the inflation inlet of the air bag 2 through the flexible air pipe 3, so that daily actions of people are not influenced. When the position indicator is started automatically or manually, the control switch releasing device 4 opens the inflating tank 5 to inflate the air bag 2, the air bag 2 stretches the built-in antenna to be perpendicular to the sea level after inflation, and the air bag is connected with the position indicator through a feeder line. After the air bag 2 is inflated, the air bag and the antenna 6 in the air bag are lifted into the air, so that the height of the antenna is increased, and the communication distance is increased.
The personnel water falling indication mark with the air bag floating antenna provided by the invention is characterized in that the antenna 6 is a bendable folding antenna and can be stretched and expanded along with the inflation and expansion of the air bag 2. The bottom inflation port of the air bag 2 is provided with a one-way valve structure, namely, the bottom of the air bag 2 is provided with a valve structure which can only charge air in one direction in the air bag, and the switch release device 4 can be an electromagnetic valve; the flexible inflation tube 3 is connected with the electromagnetic valve 4 through a locking device 8 capable of controlling falling off. The inflation time can be controlled by the position indicator through the electromagnetic valve 4, and after the timing arrives, the control locking device 8 disconnects the inflation tube from the electromagnetic valve 4, and the air bag naturally rises by buoyancy.
For simplicity, the invention can also directly form a tearable nick on the flexible gas-filled tube 3, and directly adopts a bolt as the switch releasing device 4, wherein the tearing force of the flexible gas-filled tube 3 is smaller than the rising buoyancy of the gas bag 2 filled with light gas, and the high-pressure light gas is preferably hydrogen, helium and other gases with smaller molecular weight; when in emergency use, the plug is only required to be pulled out, so that the safety and reliability are improved; at this time, the length of the antenna feeder line 1 can be far longer than that of the flexible inflation tube 3, so that the communication action distance of the water falling indication position mark is better improved, the probability of the water falling personnel being found is improved, and the search and rescue efficiency is improved.
