Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifebuoys, in particular to a projectile lifebuoy with a shark-proof function. Background Technique
[0002] The sea is popular among the general public for its vastness and mystery. Many people like to travel to the seaside and surf or swim in the sea. However, there are many dangerous animals in the sea, and the most harmful one is the shark. Sharks are carnivorous animals and have a wide range of hunting areas. Therefore, there are a large number of reports of sharks biting humans every year. When in danger at sea, a lifebuoy is used for escape. However, the traditional lifebuoy has a simple structure and cannot fight against sharks, so the safety of personnel cannot be guaranteed when encountering sharks at this time. Content of the Utility Model
[0003] The purpose of the utility model is to provide a projectile lifebuoy with a shark-proof function to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A projectile lifebuoy with a shark-proof function, including a lifebuoy main body. A towing rope is connected in the middle of the lifebuoy main body. A plurality of connecting ropes are fixedly connected to the outer side wall of the lifebuoy main body. The top ends of the connecting ropes are fixedly connected with a shark-proof cylinder. A partition plate is fixedly connected in the middle of the shark-proof cylinder. A rotating column is rotatably connected in the middle of the partition plate. A plurality of fan blades are fixedly connected to the side end of the rotating column. An underwater whistle is fixedly connected to the middle of the lower end of the shark-proof cylinder. An air guide plate is fixedly connected to the inner wall of the shark-proof cylinder. A telescopic airbag is fixedly connected to the side end of the air guide plate. The lower end of the rotating column extends to the telescopic airbag. A communicating pipe is fixedly connected between the air guide plate and the underwater whistle.
[0005] Preferably, both ends of the rotating column penetrate through the partition plate. The fan blades are located above the partition plate. A plurality of diversion openings are provided on the side end of the shark-proof cylinder, and the diversion openings are located above the partition plate.
[0006] Preferably, an extrusion head is fixedly connected to the side end of the rotating column. The extrusion head is located on the side end of the telescopic airbag. A guide plate is fixedly connected to the top end of the telescopic airbag, and the guide plate is of an arc-shaped structure.
[0007] Preferably, a plurality of conduction sheets are fixedly connected to the side end of the shark-proof cylinder, and the conduction sheets are elastic iron sheets.
[0008] Preferably, an auxiliary airbag is fixedly connected to the top end of the underwater whistle. The telescopic airbag, the air guide plate, the communicating pipe, the underwater whistle and the auxiliary airbag are interconnected. After the underwater whistle is ventilated, it emits a high-frequency sound or the sound of a shark's natural enemy animal.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: A towing rope is tied to the lifebuoy main body. After the lifebuoy main body is projected, the lifebuoy can be towed back through the towing rope, which is convenient for projecting the lifebuoy main body multiple times to the people in danger and can quickly rescue the people; A plurality of shark-proof cylinders are arranged at the side end of the lifebuoy main body. When the lifebuoy main body moves in the water, the water flow will drive the rotating column in the shark-proof cylinder to rotate, so that the underwater whistle emits high-frequency sounds or the sounds of shark natural enemies, thereby driving away sharks and ensuring the safety of the rescued people.

Detailed Implementation Manner
[0014] In order to deepen the understanding and recognition of the present utility model below, the technical solutions in the embodiments of the present utility model will be clearly and completely described and introduced in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and no formal restrictions are imposed on this embodiment. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0015] Please refer to Figures 1-3The traction rope 2 is connected to the outer wall of the lifebuoy body 1, and a plurality of connecting ropes 4 are fixedly connected to the outer wall of the lifebuoy body 1. The top of the connecting rope 4 is fixedly connected to the anti-shark tube 3, and the middle of the anti-shark tube 3 is fixedly connected to the dividing plate 13. The middle of the dividing plate 13 is rotatably connected to the rotating column 5. The side end of the rotating column 5 is fixedly connected to a plurality of fan blades 6. The lower end of the anti-shark tube 3 is fixedly connected to the underwater whistle 9. The inner wall of the anti-shark tube 3 is fixedly connected to the air guide plate 8. The side end of the air guide plate 8 is fixedly connected to the telescopic air bag 15. The lower end of the rotating column 5 extends to the telescopic air bag 15. A connecting pipe 10 is fixedly connected between the air guide plate 8 and the underwater whistle 9.
[0016] Both ends of the rotary column 5 penetrate through the partition plate 13 , the fan blade 6 is located at the upper end of the partition plate 13 , and the side end of the anti-shark cylinder 3 is provided with a plurality of flow guides 7 , and the flow guides 7 are located at the upper end of the partition plate 13 . When the lifebuoy main body 1 moves, sea water will enter the anti-shark cylinder 3 along the flow guide, thereby driving the fan blade 6 and the rotary column 5 to rotate.
[0017] The side end of the rotating column 5 is fixedly connected to an extrusion head 14, which is located at the side end of the telescopic airbag 15. The top of the telescopic airbag 15 is fixedly connected to a guide plate 16, which is an arc-shaped structure. The side end of the anti-shark cylinder 3 is fixedly connected to multiple conductive plates 12, which are elastic iron plates. The top of the underwater whistle 9 is fixedly connected to an auxiliary airbag 11. The telescopic airbag 15, the air guide plate 8, the connecting pipe 10, the underwater whistle 9 and the auxiliary airbag 11 are connected to each other. After ventilation, the underwater whistle 9 emits a high-frequency sound or the sound of shark's natural enemy. When the rotating column 5 rotates, it drives the extrusion head 14 to squeeze the guide plate 16, thereby compressing the telescopic airbag 15 and compressing the gas in the telescopic airbag 15 into the auxiliary airbag 11. When the gas flows, it passes through the underwater whistle 9, and the underwater whistle 9 can emit a sound that sharks hate. The sound can be conducted and diffused by the conductive plate 12, thereby dispersing nearby sharks and ensuring the safety of the rescued people.
