technical field

The utility model relates to a position indicator for falling into water, in particular to a position indicator for personnel falling into water with an air bag floating antenna.

Background technique

Man Overboard Position Indicator, referred to as MOB (MOB-ManOverBoard), is a personal emergency radio signal transmitting device. When a man falls into danger, it is activated manually or automatically, and sends a distress alarm including the identity and location of the man to surrounding ships through the VHF frequency band. information. In order to increase the probability of the surrounding ships finding people in distress, it is hoped that the wireless communication distance of the position indicating beacon should be as far as possible.

Since VHF communication adopts line-of-sight propagation. The height of the antenna from the sea level is proportional to the communication distance, the higher the antenna, the farther the communication distance will be. However, if the antenna is too high, it will affect the convenience of installation and use. How to effectively increase the antenna height of the man-overboard position-indicating beacon so as to increase the communication range without affecting the convenience of use has always been a technical problem that needs to be solved urgently in this field.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is to provide a person falling-in-water indicator with an airbag floating antenna, including the falling-in-water indicator, wherein the falling-in-water indicator is connected to the antenna through an antenna feeder, The antenna is arranged in the airbag, and the inflation port of the airbag is connected with the inflatable tank through a flexible inflation tube, and a switch release device is arranged at the connection between the flexible inflatable tube and the inflatable tank.

The above-mentioned man-overboard position indicator with air bag floating antenna, wherein, the airbag is folded as a whole and installed on the top of the over-water indicator, and the inflatable tank and switch release device are fixed at the middle and lower part of the over-water indicator.

In the above-mentioned man overboard position indicator with airbag floating antenna, the antenna is a bendable and foldable antenna that can be stretched and expanded as the airbag is inflated.

In the above-mentioned man overboard position indicator with an airbag floating antenna, the inflation port at the bottom of the airbag has a one-way valve structure, and the flexible inflation tube is connected to the switch release device through a locking device that can be controlled to fall off.

In the above-mentioned man-overboard position indicator with airbag floating antenna, the inflatable tank is provided with high-pressure light gas, and the material of the inflatable tank is light metal material.

Compared with the prior art, the utility model has the following beneficial effects: The utility model provides a person falling into the water position indicator with an airbag floating antenna. By adding an airbag to the falling water position indicator, the airbag is equipped with an antenna, and the airbag and the high voltage The inflatable tank of light gas is connected; after the airbag is inflated, it rises into the air together with the antenna in the airbag, thereby greatly improving the communication distance of the falling water position indicator, increasing the probability of the person falling into the water being found, and improving the search and rescue efficiency; at the same time, it does not affect the convenience of use performance, simple structure, and easy implementation.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 is a schematic diagram of the structure of the man-overboard indicator with the airbag floating antenna of the utility model when it is not activated; Figure 2 is a structural schematic diagram of the utility model of the man-overboard indicator with the airbag floating antenna after it is activated.

Please refer to Fig. 1 and Fig. 2, the personnel falling-in-water indicator with the airbag floating antenna provided by the utility model includes the falling-in-water indicator 7, wherein, the falling-in-water indicator 7 is connected to the antenna 6 through the antenna feeder 1, The antenna 6 is arranged in the airbag 2, and the inflation port of the airbag 2 is connected with the inflatable tank 5 through the flexible inflatable tube 3, and a switch release device 4 is arranged at the joint between the flexible inflatable tube 3 and the inflatable tank 5.

The utility model provides a person falling into the water indicator with an air bag floating antenna. On the basis of the original person falling into the water indicator 7, an airbag 2 and a small inflatable tank 5 with built-in high-pressure light gas are added. The inflatable tank 5 The material is light metal material. When the position indicator is not activated, the antenna 6 is neatly placed in the airbag 2, and the airbag is installed on the top of the position indicator after being folded as a whole. The air pipe 3 is connected to the inflation port of the air bag 2, which does not affect the daily actions of the personnel. When the position indicator starts automatically or manually, the control switch release device 4 opens the inflatable tank 5 to inflate the airbag 2. After the airbag 2 is inflated, the built-in antenna is stretched to be perpendicular to the sea level, and the airbag is connected to the position indicator through a feeder. After the airbag 2 is inflated, it rises into the air together with the antenna 6 in the airbag, thereby increasing the height of the antenna and improving the communication distance.

The utility model provides a person falling into the water position indicator with an airbag floating antenna. The antenna 6 is a bendable and foldable antenna, and can be stretched and expanded as the airbag 2 is inflated. The bottom inflation port of the airbag 2 has a one-way valve structure, that is, a valve structure that can only be inflated in one direction inside the airbag is provided at the bottom of the airbag 2, and the switch release device 4 can be a solenoid valve; the flexible inflation tube 3 It is connected with the solenoid valve 4 through a locking device 8 that can be controlled to fall off. The inflation time can be controlled by the position indicator through the electromagnetic valve 4. After the timing is up, the control locking device 8 disconnects the connection between the inflation tube and the electromagnetic valve 4, and the air bag is naturally lifted into the air by buoyancy.

For the sake of simplicity, the utility model can also directly form a tearable notch on the flexible inflatable tube 3, and directly use the latch as the switch release device 4, the tearing force of the flexible inflatable tube 3 is less than that of the air bag 2 filled with light The rising buoyancy of the high-pressure light gas is preferably hydrogen, helium and other gases with smaller molecular weights; in emergency use, it is safer and more reliable as long as the latch is pulled; at this time, the length of the antenna feeder 1 can be It is much longer than the length of the flexible inflatable tube 3, so as to better improve the communication distance of the falling-in-water position-indicating beacon, increase the probability of people in the water being found, and improve the efficiency of search and rescue.
