Description

Technical Field

[0001] The present invention relates to the technical field of water rescue, and particularly relates to a pneumatic buoyancy rescue clip. Background Art

[0002] Water rescue refers to the rescue measures taken when accidents occur during people's water activities, which are divided into still water rescue and wave rescue. The development of water rescue abroad has a long history. Many countries in Europe established life-saving associations at the end of the 19th century to promote life-saving knowledge, improve life-saving skills, strengthen the training of lifeguards, and carry out research on life-saving theory. After a development process of more than a hundred years, countries such as the United Kingdom, Australia, the United States, and Canada have gradually formed a relatively perfect life-saving management system and lifeguard training model. Water rescue is related to people's life safety, and cultivating water rescue talents is to provide people with a safe fitness and entertainment place. However, people know very little about life-saving technology, and water rescue in China urgently needs to develop rapidly.

[0003] However, in the prior art, when a person drowns in water, buoyancy is provided through a life buoy or a life jacket for auxiliary rescue. However, when throwing a life buoy or a life jacket to a conscious drowning person in the water, the drowning person may not be able to accurately judge and use it due to panic or thrashing. If the drowning person is unconscious, they cannot use the rescue equipment independently. At this time, a lifeguard needs to jump into the water for dragging rescue, and the risk of the rescuer drowning will also increase during the dragging rescue. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] The present invention provides as Figures 1-6 shown, a pneumatic buoyancy life-saving clip includes a buoyancy component 1, a clamping component 2 and a connection component 3. The clamping component 2 is arranged on the buoyancy component 1 and is used for turning over and clamping a drowning person in water.

More specifically, the air vent block 206 is injected with gas. The air vent block 206 guides and transmits the gas into the cylinder 205. The cylinder 205 receives the gas and operates. The output rod of the cylinder 205 extends and pushes the T-shaped block 207. The T-shaped block 207 is pushed to move out of the mounting cover 201. When the T-shaped block 207 moves, it drives the toothed plate 208 to move. The toothed plate 208 is in meshing transmission with the incomplete wheel 203, so that while the toothed plate 208 moves, it rubs and drives the incomplete wheel 203 to rotate. The incomplete wheel 203 rotates and drives the round rod 202 and the connecting block 204 to rotate. The round rod 202 rotates in the mounting cover 201. The connecting block 204 drives the arc-shaped rod 102 to rotate and move towards the center, so that the buoyancy assembly 1 hoops the body of the drowning person and provides buoyancy to lift. It has the advantages of clamping and providing buoyancy to lift when rescuing a drowning person, preventing the drowning person from losing consciousness and being unable to use the rescue equipment due to panic or thrashing, and reducing the possible risks that the rescuers may encounter when entering the water.

[0021] In addition, a tee pipe is fixedly mounted at the bottom of the two air vent blocks 206.

[0023] In addition, two tether rings are fixedly mounted on one outer wall of the mounting cover 201. By installing the two tether rings, before the rescue, the rescuers can tie the rescue rope. During the rescue process, the tied rescue rope can be used for pulling, quickly dragging the drowning person to the shore. It is faster than the rescuers entering the water to drag, and has the advantage of quickly dragging the drowning person to the shore. In addition, the splicing assembly includes a C-shaped plate 209 and an insert plate 210. The C-shaped plate 209 is fixedly mounted on the bottom of the mounting cover 201.

More specifically, the connecting block 204 drives the arc rod 102 to rotate and move closer to the center, so that the arc rod 102 is clamped on the body of the drowning person and lifted up by the buoyancy provided by the buoyancy ball 103. When the ventilation block 206 guides air, the ventilation block 206 guides air to the pneumatic push rod 104 through the hose. The gas is introduced into the pneumatic push rod 104 through the hose and started. The pneumatic push rod 104 is started and extended. The pneumatic push rod 104 extends and pushes the arc rod 102 to move and unfold, expanding the clamping circle. When the pneumatic push rod 104 is extended, it drives the outer folding plate 105 and the inner folding plate 106 to fold toward the pneumatic push rod 104. After the person who falls into the water is buckled, the reverse operation is performed to shrink the circle. It has the advantages of lifting the person who falls into the water and clamping it tightly to adapt to people of different sizes.

Connect the docking pipe 306 to an external air compressor. Pull the hollow telescopic rod 304 to extend it, so that the mounting cover 201 moves away from the take-up reel 301. When the mounting cover 201 moves, the air supply pipe 302 is also pulled. The air supply pipe 302 rotates and extends in length on the take-up reel 301 when being pulled. Throw the arc-shaped rod 102 into the water and move it closer to the drowning person. Start the external air compressor to compress air and inject it into the docking pipe 306.
