Description

Secondary detachable life buoy

technical field

The invention relates to a water lifesaving device, in particular to a water lifesaving buoy which can be separated to the water surface and high altitude.

Background technique

Emergency buoys are key equipment in underwater equipment such as submersibles. When abnormal conditions occur in underwater equipment, they are used to mark the position of the submersible and facilitate search and rescue by rescuers. Under the existing technology, life-saving buoys, especially those used in deep-sea equipment, generally can only float to the surface of seawater due to the limitation of ropes, and can be searched by sea personnel through internal strobe lights and signal transmitters. But in actual use, the target of the buoy floating on the surface of the sea is small, and the search process is like finding a needle in a haystack, which consumes a lot of manpower and material resources and also delays precious rescue time. In view of the shortcomings in the above-mentioned prior art, the applicant provides a deep-sea-high-altitude two-stage detachable lifesaving buoy, that is, after the buoy floats to the surface of the sea, it is separated, and part of the information carried by the buoy can be sent to an altitude of 10,000 meters. for rescue forces to search for.

The piston rod of the cylinder is vertically arranged, and the end of the piston rod is connected with a vertical cutting knife, and the cutting knife is located between the one-way valve and the high-pressure gas cylinder. The water outlet sensor is installed on the buoy; the water outlet sensor, solenoid valve and cylinder are all connected to the control unit through the control cable, and the control unit is fixed on the buoy.

Its further technical scheme is:

The electromagnetic valve adopts a two-position two-way electromagnetic reversing valve.

The compressed balloon is connected with positioning information and a signal transmitting device.

The electromagnetic valve is arranged on the side of the pipeline close to the high-pressure gas cylinder, and the one-way valve is arranged on the side of the pipeline close to the compressed balloon.

Technical effect of the present invention:

In the present invention, a compressed balloon and an inflating device and a cutting device for the compressed balloon are arranged on the buoy, so that after the buoy is released, the dual positioning functions of the buoy floating on the water surface and sending out a positioning signal, and the compressed balloon floating in the air and sending out a positioning signal can be realized. Rescuers search, improving rescue efficiency and success rate.

detailed description

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

See Fig. 1, the present invention comprises buoy 1, and buoy 1 is connected with underwater equipment by cable 2, and buoy 1 has strobe light 3, and buoy 1 is provided with high-pressure gas cylinder 4, and high-pressure gas cylinder 4 is connected with compression by pipeline 5. The opening of the balloon 6 is sealed and connected, and the pipeline 5 is provided with a solenoid valve 7 and a one-way valve 8. Specifically, the solenoid valve 7 is arranged on the side of the pipeline 5 close to the high-pressure gas cylinder 4, and the one-way valve 8 is arranged on the pipeline 5. Near the side of the compressed balloon 6, the buoy 1 is fixed with a cylinder 9, the piston rod of the cylinder 9 is vertically arranged, and the end of the piston rod is connected with a vertically arranged cutting knife 10, and the cutting knife 10 is located at the one-way valve 8 Directly below the pipeline section between the high-pressure cylinder 4; the buoy 1 is provided with a water outlet sensor 11, the water outlet sensor 11, the solenoid valve 7 and the cylinder 9 are all connected to the control unit 13 through the control cable, and the control unit 13 is fixed on the buoy 1 on.

The compressed balloon 6 is connected with positioning information and signal transmitting device 12, and positioning information and signal transmitting device 12 are prior art, specifically, can adopt simple strobe light, or adopt wifi signal transmitter, GPS receiver and processor The formed wireless positioning information device.

Cylinder 9 further adopts high-pressure cylinder 4 to provide power source, and described one-way valve 8 is a commercially available product, preferably cone valve, and solenoid valve 7 adopts two-position two-way electromagnetic reversing valve, and the normal state of solenoid valve 7 is pipeline 5 It is a non-connected state. After the electromagnet is energized, the spool of the solenoid valve 7 moves, and the pipeline section between the solenoid valve 7 and the check valve 8 is connected. The mode of operation of the present invention is as follows:

Figure 1 shows that the compressed balloon 6 is in an uninflated original state when the underwater equipment is in normal operation. When an emergency occurs, the buoy 1 is released and the buoy 1 floats to the water surface. Then the water outlet sensor 11 detects water outlet, and the water outlet sensor 11 sends a water outlet signal to Control unit 13, the control unit 13 controls to open the electromagnetic valve 7, at this time, the pipeline section between the one-way valve 8 and the electromagnetic valve 7 is connected, and the high-pressure gas in the high-pressure gas cylinder 4 is filled between the one-way valve 8 and the electromagnetic valve 7 In the pipeline section between, when the pressure in the pipeline section reaches a certain value, the valve core in the one-way valve 8 will be pushed back, thereby opening the one-way valve 8, so that the entire pipeline 5 is connected, and the high-pressure gas cylinder 4 Inflate the compressed balloon 6, the compressed balloon 6 expands, and the inflated state is shown in Figure 2; the control unit 13 sets a certain inflation time, and when the inflation time is up, the control unit 13 sends an instruction to control the action of the cylinder 9, the action of the cylinder 9, and the movement of the cylinder 9 The piston rod of the cylinder protrudes upwards, thereby driving the cutting knife 10 to move up until the pipeline 5 is cut off.
