Description

Throwing Life Tube {THROWABLE TYPE LIFE-SAVING TUBE}

The present invention relates to a lifesaving device that can be used in an emergency in water, and more particularly to a throwing life tube.

Most life-threatening accidents in water play are determined by fate within the first 30 seconds of an accident. This is a situation we can think of, such as tumbling to find equipment for rescue or others jumping into the water for rescue. In many cases, you can use a rope or tube nearby to get to the rescue, but most accidents are unpredictable, so there are virtually no tubes or ropes nearby.

In addition, it is not easy to throw a tube to the accident point due to the size of the tube, even when the structure is used by using the tube. In general, lifeboats are tied to a rope at regular intervals, and in the event of an accident, these lifetubes are thrown into life. However, these tubes are not easy to handle in terms of volume or weight. Moreover, carrying is almost impossible.

The present invention is a throwing life-saving tube that improves this problem, while maintaining the contracted state to facilitate the throwing in the usual time, when throwing to the accident point is in contact with water and automatically expands after a certain time to have a tube form. Throwing tube according to the present invention has a merit that can be accurately thrown at the point of accident because it is easy to carry and is easy to carry because it is small in size. In addition, the throwing life-saving tube according to the present invention is divided into a number of tubes there is an advantage that the function is maintained even if some tubes are damaged. In addition, it is possible to prevent the person injured by the debris of the outer shell during the expansion, as well as to prevent malfunction by expanding in water.

The sensor must be sensitive in order to be pressed by the hydraulic pressure or at a deep depth where the hydraulic pressure is considerably high. If the sensitivity is sensitive, it is more likely to expand in undesired situations when carrying it, and if it is expanded at deeper waters, it is more likely to rise to the surface and out of the distress, causing the throwing tube to jump out to save lives. In order for this to be undesirable Self-explanatory Further, no other features of the throwing life tube of the present invention described below are mentioned at all.

Reference numerals 510, 511, 512 and 513 denote electrode pads. The resistance value or capacitance between the electrode pads 510 and 511 is measured by the measuring means 520, and the resistance value or capacitance between the electrode pads 512 and 513 is measured by the measuring means 521. Next, the resistance value or capacitance between the electrode pads 510 and 511 and the resistance value or capacitance between the electrode pads 510 and 511 are compared in advance, and the difference is corrected through the correction means 530 and 531, and the comparison means ( In 540, when the signal values input from the correction means 530 and 531 coincide with each other, the sensor detects that it is underwater and outputs a detection signal.

6 is a circuit diagram in which the underwater sensing sensor specifically illustrates a circuit, where P10 and P11 are sensor electrode pads for detecting underwater, Q10 is an output transistor for detecting underwater, and R10 is a resistor for adjusting detection sensitivity. R11 is an output resistance for detecting that it is underwater, R12 is a resistance for correcting the difference between the resistance or capacitance value measured between the resistance or capacitance value and other sensor electrode pads between P10 and P11, and V10. Is the voltage source and V _ref is the reference voltage at which V10 is adjusted by resistor R12. Controlled S10 is a power supply switch and OUT1 is an output terminal for detecting that it is underwater. The underwater sensing circuit shown in FIG. 6 is mounted on an electronic printed circuit board, not shown. The underwater sensing circuit is waterproof except for the sensor electrode pads P10 and P11.

When using the throwing life tube according to the present invention, it is necessary to remove the power pin (S10 in Fig. 6) mounted on the surface. When this power supply pin is fixed, no power is supplied as shown in Fig. 6, in which case the power supply has no power consumption other than natural discharge. When the power pin is removed, S10 is turned on, and when the throwing tube is immersed in water by throwing, the two sensor electrode pads P10 and P11, P12 and P13 are electrically connected. These circuits are connected to a detection and amplification circuit when the current flow is greater than V _ref comparison with a predetermined V _ref is obtained a water-lock detection result. That is, at normal times (after removing the power pin), the current flowing from the supply voltage V10 to the resistor R10 is weak. When immersed in water, a large current flows. At this time, the transistor Q10 is biased and the emitter and the collector of the transistor Q10 are turned on, so that the output value detected by the output terminal OUT1 of the resistor R11 is detected. Will be represented.

In other words, when both OUT1 and OUT2 are in the ON state, it is expanded. Although not shown, it is obvious that the resistance (corresponding to R12) of another sensor that determines V _ref is designated in consideration of the resistance or capacitance between the measured sensor electrode pads in order for OUT2 to be turned on.

In addition, in order for the above-described underwater sensor to operate normally in the throwing life-saving tube according to the present invention, it is preferable that the main body is higher than the specific gravity of water (river water, sea water) and sinks in water.

In addition, the self-display device (LED) may be installed to display to the user that the throwing life-saving tube according to the present invention can operate normally after the power pin is removed. That is, an LED is installed between the power supply pin and the detection circuit to enable the LED to be turned on when the power supply pin is removed.

In addition, the sounding device may be installed to display to the user that the throwing life-saving tube according to the present invention can operate normally after the power pin is removed. That is, a sounding device may be installed between the power supply pin and the detection circuit so that a user may hear a specific sound when the power supply pin is removed.

In addition, for safer operation, the throwing life-saving tube according to the present invention further includes a time delay circuit to detect that the underwater sensor is underwater and allow the airbag to be deployed after a certain time (for example, about 1 second) passes. Can be.

In addition, by disposing a plurality of structural straps around the airbag of the throwing life-saving tube according to the present invention so that the distress can easily catch.
