[0002] Underwater rescue refers to the action of rescuing people in distress in an underwater environment, which involves a variety of rescue methods and professional equipment. There are many different methods of underwater rescue, depending on the distress situation and the professional capabilities of the rescue team. For example, if the rescuer needs to go into the water to rescue a drowning person, he can use the towing method, go around the back of the drowning person, pull the armpit to drag him ashore, or dive underwater, go around the chest from the left armpit of the drowning person, hold his right hand, and drag him to the shore in a supine position.

Step 2: When in use, put the waist sleeve on the waist of the wearer, and then put the mouthpiece on the teeth on the lower jaw in the mouth. When the lifeguard needs to rescue the drowning person, the lifeguard quickly swims to the vicinity of the drowning person, then dives down, and hugs the drowning person. At this time, the lifeguard bites the elastic block with his teeth through the power of the upper jaw, causing the elastic block to deform. At this time, the elastic block pushes the liquid inside the first liquid bag to be input into the inside of the drive box through the hose, and then the liquid is discharged through the connecting pipe. At this time, the liquid pushes the fan blade to drive the valve stem to rotate, so that the first switch valve is opened, so that the carbon dioxide gas inside the first gas cylinder enters the inside of the airbag ring through the first switch valve, so that the airbag ring expands, and the protective cover is pushed away, so that the airbag ring is unfolded, so that the lifeguard quickly floats to the surface of the water with the drowning person; Step three: when the lifeguard enters the water, under the action of water pressure, water enters the movable groove through the water hole, and the first push block is lifted. At this time, the liquid in the liquid cavity is sucked into the first piston block through the first connecting pipe. Then, when floating up quickly, the water hole contacts the air.

The lifeguard then moves the second piston column to the top of the rescuer's bag, and then the lifeguard can pull out the lock hook and hook it on the second fixing ring so that the lifeguard can swim and drive the lifeguard bag and the drowning person to move. Step 4: If tourists fall into the water and float themselves up through the above steps, they can rotate the first fixed block to make the first fixed block drive the sealing ring to rotate inside the annular cavity and adjust the position of the lock hook. Another person can adjust the position of the first fixed ring by rotating the second rotating ring. Then all tourists can pull out the lock hook and hook the lock hook on the first fixed ring of another person, so as to build a life-saving valve body through the device on the tourists. If the airbag ring of one of the devices leaks accidentally, the airbag ring on the device on other tourists can provide buoyancy. At the same time, the tourists who fall into the water will not be scattered by the water flow, which is convenient for rescue.

[0012] The present invention provides an underwater rescue emergency device and method, which has the following beneficial effects: 1. The underwater rescue emergency equipment and method are provided with a waist cover, an airbag ring and a storage chamber. When falling into water, the user will dive, and then the airbag ring will expand to lift the user. At this time, the second switch valve opens, so that the paint inside the storage chamber passes through the second switch valve, the annular cavity and the discharge hole to fall into the water body near the user, dyeing the water body near the user, so as to mark the user on the water surface, so as to search and rescue the user.

[0013] 2. The underwater rescue emergency equipment and method are provided with a fixed rope, a locking hook and a first fixing ring. After the lifeguard floats up, he can unlock the buckle on the strap, and then expand the life-saving airbag bag, then open the valve, discharge the gas in the second gas cylinder into the life-saving airbag bag, and then quickly expand the life-saving airbag bag into a life-saving valve, place the drowning person on the top of the life-saving airbag bag, and then the lifeguard can pull out the locking hook and hook the locking hook on the second fixing ring, so that the lifeguard can swim and drive the life-saving airbag bag and the drowning person to move. If tourists fall into the water, the above steps can be used to make the lifeguard self-rescued. After floating, the first fixing block can be rotated to make the first fixing block drive the sealing ring to rotate inside the annular cavity to adjust the position of the locking hook, and another person can adjust the position of the first fixing ring by rotating the second rotating ring. Then all tourists can pull out the locking hook and hook the locking hook on the first fixing ring of another person, so as to build a life-saving valve body through the device on the tourists. If the air bag ring of one of the devices leaks accidentally, the air bag ring on the device on other tourists can provide buoyancy, and at the same time, the tourists who fall into the water will not be scattered by the water flow, so the tourists who fall into the water can be gathered to facilitate rescue.
