A water rescue life vest

Abstract

This invention discloses a water rescue life jacket, belonging to the technical field of rescue life jackets. It includes: a life jacket body; a rigid guide plate fixedly connected to the back of the life jacket body; and two positioning blocks with multiple straps. After the life jacket body is put on, the positioning blocks are secured to the rescuer's calves using the straps. During normal rescue operations, the auxiliary propulsion device and the ring-shaped cutting mechanism are engaged with the rigid guide plate, preventing interference with the rescuer's swimming movements. In waters with aquatic plants, the auxiliary propulsion device and the ring-shaped cutting mechanism are engaged with the positioning blocks, allowing the rescuer to lean back. The rigid guide plate separates the life jacket body from the aquatic plants, eliminating the need for leg movements to avoid entanglement. The rescuer only needs to activate the auxiliary propulsion device for underwater propulsion, and the ring-shaped cutting mechanism cuts through the aquatic plants that obstruct the propulsion device, thus preventing the rescuer from becoming entangled. This improves rescue efficiency and ensures the safety of both the rescuer and the rescued.

Description

Technical Field

[0001] This invention belongs to the field of rescue life jacket technology, and particularly relates to a water rescue life jacket. Background Technology

[0002] Rescue life jackets are core equipment for water safety, and their design must take into account buoyancy, durability, fit, and adaptability to different scenarios.

[0003] Currently, rescuers expend a lot of energy during the rescue operation. In the absence of professional rescue power equipment, especially when encountering rescue waters with dense aquatic plants, it is difficult to bring the rescued person to a safe area. Rescuers are easily entangled in the aquatic plants, which will reduce the efficiency of the rescue and threaten the safety of both the rescuers and the rescued person. Summary of the Invention

[0004] The purpose of this invention is to provide a water rescue life jacket in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water rescue life jacket, comprising: The life jacket itself; A rigid drainage plate is fixedly connected to the back of the life jacket body; Two positioning blocks, each with multiple straps attached; Two sets of auxiliary thrusters are engaged with the rigid guide plate and / or the positioning block; Two sets of annular cutting mechanisms are engaged with the rigid guide plate and / or the positioning block, and the two sets of annular cutting mechanisms are respectively aligned with the two sets of auxiliary pushers; A waterproof battery pack is fixedly connected to the rigid guide plate, and the waterproof battery pack is electrically connected to the two sets of auxiliary thrusters and the two sets of annular cutting mechanisms.

[0006] As a further description of the above technical solution: The auxiliary thruster is provided with a first positioning component, and both the rigid guide plate and the positioning block are provided with positioning grooves that match the first positioning component, and the first positioning component is engaged in the positioning groove.

[0007] As a further description of the above technical solution: The annular cutting mechanism includes a fixed ring, multiple vibrating heads, and multiple arc-shaped blades. A second positioning element is provided on the fixed ring, which is engaged in the positioning groove. The axis of the fixed ring coincides with the axis of the auxiliary pusher. The multiple vibrating heads are fixedly connected in the fixed ring. The multiple arc-shaped blades are arranged in a circular array, and each of the multiple arc-shaped blades is fixedly connected to a multiple of the vibrating heads. The vibrating heads are electrically connected to the waterproof battery pack.

[0008] As a further description of the above technical solution: The first positioning member and the second positioning member, which are located in the same positioning groove, are connected by a shock-absorbing pad.

[0009] As a further description of the above technical solution: The cross-sections of the first positioning element, the second positioning element, and the positioning groove are all T-shaped.

[0010] As a further description of the above technical solution: The vibrating head is the main body of the ultrasonic scalpel.

[0011] As a further description of the above technical solution: The fixed ring has multiple arc-shaped grooves at its end, and the multiple arc-shaped blades are slidably connected in the multiple arc-shaped grooves respectively.

[0012] As a further description of the above technical solution: The auxiliary thruster is a shaftless thruster.

[0013] As a further description of the above technical solution: The life jacket body is equipped with multiple control buttons, which are electrically connected to multiple vibration heads, two sets of auxiliary thrusters, and the waterproof battery pack.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, after the life jacket body is put on, the positioning block is fixed to the rescuer's lower leg with straps. During normal rescue, the auxiliary thruster and the ring cutting mechanism are locked onto the rigid guide plate, which will not interfere with the rescuer's swimming movements. When rescuing in waters with aquatic plants, the auxiliary thruster and the ring cutting mechanism are locked onto the positioning block, and the rescuer leans back. The rigid guide plate separates the life jacket body from the aquatic plants. The rescuer does not need to swing his legs to avoid being entangled by the aquatic plants. He only needs to activate the auxiliary thruster for underwater propulsion. The ring cutting mechanism cuts the aquatic plants that are obstructing the auxiliary thruster, which can prevent the rescuer from being entangled by the aquatic plants, improve rescue efficiency, and ensure the safety of both the rescuer and the rescued.

[0015] 2. In this invention, the high-frequency vibrating head acts on the arc-shaped blade, thereby instantly cutting the aquatic plants that come into contact with the arc-shaped blade. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 The present invention provides a technical solution: a water rescue life jacket, comprising: Life jacket body 1; A rigid drainage plate 2 is fixedly connected to the back of the life jacket body 1; Two positioning blocks 3, on which multiple straps 4 are installed; Two sets of auxiliary thrusters 5 are engaged with the rigid guide plate 2 and / or the positioning block 3; Two sets of annular cutting mechanisms 6 are engaged with the rigid guide plate 2 and / or the positioning block 3, and the two sets of annular cutting mechanisms 6 are respectively aligned with the two sets of auxiliary pushers 5; A waterproof battery pack 7 is fixedly connected to the rigid guide plate 2, and the waterproof battery pack 7 is electrically connected to two sets of the auxiliary thrusters 5 and two sets of the annular cutting mechanisms 6. The auxiliary thruster 5 is provided with a first positioning element 8, and both the rigid guide plate 2 and the positioning block 3 are provided with positioning grooves 9 that match the first positioning element 8. The first positioning element 8 is engaged in the positioning groove 9. The annular cutting mechanism 6 includes a fixed ring 61, multiple vibrating heads 62, and multiple arc-shaped blades 63. A second positioning member 10 is provided on the fixed ring 61, which is engaged in the positioning groove 9. The axis of the fixed ring 61 coincides with the axis of the auxiliary pusher 5. The multiple vibrating heads 62 are fixedly connected in the fixed ring 61. The multiple arc-shaped blades 63 are arranged in a circular array, and the multiple arc-shaped blades 63 are respectively fixedly connected to the multiple vibrating heads 62. The vibrating heads 62 are electrically connected to the waterproof battery pack 7. The high-frequency vibrating vibrating heads 62 act on the arc-shaped blades 63, thereby instantly cutting the aquatic plants that come into contact with the arc-shaped blades 63. The first positioning member 8 and the second positioning member 10, which are located in the same positioning groove 9, are connected by a shock-absorbing pad 11 to prevent the operation of the auxiliary pusher 5 from being affected by the vibration generated by the vibrating head 62. The cross-sections of the first positioning member 8, the second positioning member 10, and the positioning groove 9 are all T-shaped, ensuring that the auxiliary pusher 5 and the fixing ring 61 are stably engaged on the positioning block 3 or the rigid guide plate 2. The vibrating head 62 is the main body of the ultrasonic scalpel. The main body of the ultrasonic scalpel acts on the transducer through the ultrasonic generator. The transducer converts the energy of the ultrasonic generator into the mechanical energy of high-frequency vibration. The high-frequency mechanical vibration is connected to the arc-shaped blade 63 through the amplitude transformer, so that the aquatic plants in contact with the arc-shaped blade 63 are cut off instantly. The fixed ring 61 has multiple arc-shaped grooves 12 at its end, and multiple arc-shaped blades 63 are slidably connected in the multiple arc-shaped grooves 12. The arc-shaped grooves 12 guide the movement of the arc-shaped blades 63, ensuring that the high-frequency vibration generated by the ultrasonic scalpel body will not cause the arc-shaped blades 63 to swing. The auxiliary thruster 5 is a shaftless thruster, which means that the aquatic plants entering the auxiliary thruster 5 will not only not clog the auxiliary thruster 5, but will also be crushed by the auxiliary thruster 5, resulting in good performance. The life jacket body 1 is provided with multiple control buttons 13. The control buttons 13 are electrically connected to multiple vibration heads 62, two sets of auxiliary thrusters 5 and the waterproof battery pack 7. The control buttons 13 facilitate the control of the switching on and off of the auxiliary thrusters 5 and the vibration heads 62.

[0023] Working principle: First, after the rescuer puts on the life jacket body 1, the positioning block 3 is fixed to the rescuer's lower leg using the straps 4. Second, during normal rescue, the auxiliary thruster 5 and the annular cutting mechanism 6 are engaged with the rigid guide plate 2, that is, the first positioning component 8 and the second positioning component 10 are engaged in the positioning groove 9 of the rigid guide plate 2, which will not interfere with the rescuer's swimming movements. Next, when rescuing in waters with aquatic plants, the auxiliary thruster 5 and the annular cutting mechanism 6 are engaged with the positioning block 3, that is, the first positioning component 8 and the second positioning component 10 are engaged in the positioning groove 9 of the positioning block 3. The rescuer leans back, and the rigid guide plate... The guide plate 2 separates the life jacket body 1 from the water plants. The rescuer does not need to swing their legs to avoid getting tangled in the water plants. They only need to activate the auxiliary thruster 5 for underwater propulsion, which will move the rescuer and the person being rescued normally in the water with dense water plants. Finally, the ultrasonic scalpel body acts on the transducer through the ultrasonic generator. The transducer converts the energy of the ultrasonic generator into high-frequency vibration mechanical energy. The high-frequency mechanical vibration is connected to the arc-shaped blade 63 through the amplitude transformer. Specifically, the vibrating head 62 is connected to the arc-shaped blade 63, which will instantly cut the water plants that come into contact with the arc-shaped blade 63, thus preventing the rescuer from getting tangled in the water plants.
