Anti-entanglement life raft

Abstract

The application discloses an anti-winding flight life buoy, relates to the technical field of flight life buoys, and aims to improve the safety and stability of the flight life buoy in a lifesaving process. In an actual lifesaving process, due to the water surface environment and the possibility that the rescued personnel have long hair or are bound with long strips on the body, the long strip part may float on the water surface, and in the application, the rotor in the flight life buoy is rotatably installed on the structure of the ring body; when the flight life buoy is normally transported and stored, the upper and lower surfaces of the rotor are kept close to the upper and lower surfaces of the ring body on the same water surface, so that the original storage volume is unchanged, and a new storage container does not need to be newly customized; when flight work is performed, the rotor is upwardly rotated and tilted, and then when the flight life buoy falls onto the water surface, the rotor part is higher than the water surface, so that foreign matters are effectively prevented from winding around the rotor, and the safety and stability of the flight life buoy are improved.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Figure 1-4 As shown, the present invention provides an anti-entanglement flight lifebuoy, which aims to improve the safety and stability of the flight lifebuoy during the rescue process.

[0025] In actual rescue operations, due to the water environment and the fact that the rescued person may have long hair or long objects tied to their body, the long objects may float on the water. In this application, a structure is adopted in which the rotor 2 of the flying lifebuoy is rotated and installed on the body 1. When transporting and storing the flight lifebuoy under normal conditions, the upper and lower surfaces of rotor 2 and the upper and lower surfaces of the lifebuoy body 1 remain close to the same water surface, thus ensuring that the original storage volume remains unchanged and there is no need to customize a new storage container. When the flight is in operation, rotor 2 rotates and tilts upwards. Then, when the flight lifebuoy lands on the water, part of rotor 2 is above the water surface, which effectively prevents foreign objects from getting entangled in rotor 2 and improves the safety and stability of the flight lifebuoy.

[0026] The main buoyancy-providing part of the flight lifebuoy is the body 1. In this application, the body 1 includes four buoyancy sections 11 arranged at equal intervals in the circumference. Each adjacent buoyancy section 11 is pre-set with a support shaft 12. A wiring hole 13 is opened on the upper side of the support shaft 12. The wires that need to be connected to the rotor 2 can pass through the wiring hole 13. Then, the remaining gaps on the wiring hole 13 are completely filled and sealed with a filling sealing material to ensure the original sealing performance of the body 1.

[0027] The rotor 2 includes a mounting base 4 rotatably mounted on a support shaft 12 and a housing 3 connected to the mounting base 4, wherein the housing 3 is used to install a motor, propeller, etc. The mounting base 4 has a pre-set shaft groove for assembly with the support shaft 12, and the inner wall of the shaft groove has a wiring groove communicating with a wiring hole 13. The wires passing through the wiring hole 13 enter the mounting base 4 and the housing 3 through the wiring groove; when the mounting base 4 rotates, the wiring groove can prevent the wires from being pulled, thereby ensuring the reliability of the wiring installation.

[0028] In addition, a groove 111 is pre-set on the side of the buoyancy part 11 facing the mounting base 4. The groove 111 is arc-shaped and has the same center as the support shaft 12. A limit post 41 is provided on the side of the mounting base 4 facing the buoyancy part 11. The end of the limit post 41 extends into the groove 111. When the propeller in the rotor 2 starts to rotate at high speed, the rotor 2 is subjected to the reaction force generated by the air flow and rotates upward around the support shaft 12.

[0029] The mounting base 4 has a channel for sliding the limiting post 41, and limiting posts 41 are provided on both symmetrical sides of the mounting base 4. A slide is vertically provided between the channels of the two limiting posts 41, and a control post 43 is slidably installed in the slide. Limiting concave surfaces 431 are provided on both symmetrical sides of the control post 43. One end of the limiting post 41 slides and abuts against the limiting concave surface 431. In addition, a limiting groove 112 is provided at the top of the slide groove 111. When the rotor 2 rotates upward until the limiting post 41 is aligned with the limiting groove 112, the control post 43 is moved, and the limiting post 41 is pushed out of the mounting base 4 through the limiting concave surface 431. The limiting post 41 is inserted into the limiting groove 112, thus locking the rotation of the rotor 2 after the flight lifebuoy takes off.

[0030] The mounting base 4 has an opening 44 on the side facing the duct in the rotor 2 where the propeller is mounted, which communicates with the slide rail. An air inlet 45, also communicating with the slide rail, is located on the upper or lower side of the mounting base 4. When the lifebuoy takes off, the propeller rotates at high speed, generating high-speed airflow in the duct. This airflow in the slide rail flows through the opening 44, creating a pressure difference between the two ends of the control column 43, thus achieving automated movement of the control column 43. A magnet 46 is also installed at the opening 44. When the propeller stops rotating, the attraction of the magnet 46 stably holds the control column 43, preventing it from sliding due to tilting and ensuring the rotor 2 tilts upwards throughout the entire operation of the lifebuoy.

[0031] In addition, a thrust spring 113 and a top block 114 are installed in the limiting groove 112 mentioned above. When it is necessary to reset the position of the rotor 2, the control column 43 is pushed to move into the slide. Simultaneously, one end of the limiting column 41 gradually aligns with the limiting concave surface 431. The thrust spring 113 drives the top block 114 to push the limiting column 41 out of the limiting groove 112, thereby unlocking the rotation of the rotor 2 and facilitating the storage and transportation of the flight lifebuoy.

[0032] The working principle of this invention is: When conducting a rescue using a flying lifebuoy, during the takeoff process, a downward air thrust is generated in the rotor 2, causing the rotor 2 to rotate upward until the limiting post 41 aligns with the limiting groove 112. Then, under the action of the air, the control post 43 moves and pushes the limiting post 41 into the limiting groove 112, thereby locking the rotor 2 in an upward position until it hits the water. This effectively prevents the rotor 2 from getting entangled with debris or hair on the water, greatly improving the safety of the rescue.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
