Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and in particular to an unmanned electric lifebuoy. Background Technology

[0002] Electric lifebuoys, as a modern water rescue device, integrate electric drive technology and buoyancy design, aiming to improve the efficiency and safety of water rescues through automated operation. Their core function is to use an electric drive system to achieve autonomous or remote-controlled movement, quickly approaching the person in the water, thereby reducing the risk and physical exertion of rescuers directly wading into the water. Electric lifebuoys not only provide rescuers with a safer and more efficient rescue method, but also greatly increase the survival rate of those in the water while awaiting rescue, making them an indispensable part of modern water emergency response systems.

[0003] An electric life ring with announcement number CN107336813A includes a shell, which is U-shaped. The shell has a first accommodating cavity, a second accommodating cavity, a first drain outlet, and a second drain outlet at both ends. It can move on its own, reducing the user's physical exertion, ensuring the user's life safety, and can also rescue people who have fallen into the water in a timely manner.

[0004] However, in practical applications, especially when the person in the water is extremely exhausted or unconscious, even if the electric lifebuoy arrives quickly, the person often struggles to hold onto it stably or use the handles. They may slip off the lifebuoy due to exhaustion, limiting the effectiveness of the rescue. This deficiency reflects the current equipment's inadequacy in providing basic fixation and support for the person in the water, lacking a mechanism to effectively prevent them from slipping and ensure their relative stability during the rescue. Utility Model Content

[0005] To overcome the drawback of difficulty in stabilizing a person falling into the water, this invention provides an unmanned electric lifebuoy with stabilization function.

[0006] An unmanned electric lifebuoy includes a lifebuoy, a mounting base, a first motor, gears, an outer frame, an inner frame, an outer rack, an inner rack, a compression spring, a guide rod, and an adjustment assembly. The lifebuoy, which is generally U-shaped, is connected to the mounting base at both ends. The first motor is mounted on the mounting base, and a gear is connected to the output shaft of the first motor. An outer frame is slidably connected inside the lifebuoy, and an inner frame is slidably connected inside the outer frame. An inner rack is evenly connected to the inner frame, and an outer rack is connected to the outer frame. A guide rod is connected inside the outer rack. A cavity is opened inside the inner frame, and the guide rod is slidably connected to the cavity. A compression spring is sleeved on the guide rod, with one end of the compression spring connected to the outer frame and the other end connected to the inner frame. An adjustment assembly is provided inside the lifebuoy for adjusting the position of the mounting base.

[0007] As an improvement to the above solution, the adjustment assembly includes a second motor, a connecting block, a sleeve rod, a lead screw, and a sensor. The second motor is installed inside the life ring, and a lead screw is connected to the output shaft of the second motor. A connecting block is threaded onto the lead screw, and a sleeve rod is connected to the connecting block. The sleeve rod is slidably connected to the inner stop frame and passes through the inner stop frame. A guide rod is slidably connected to the sleeve rod. A sensor is installed on the outer stop frame facing the arc-shaped area of ​​the life ring, and the sensor is wiredly connected to the second motor.

[0008] As an improvement to the above solution, a warning light is also included, with a warning light installed at the end of the outer frame.

[0009] As an improvement to the above solution, a protective shell is also included, which is rotatably connected to the life ring to cover the adjustment components.

[0010] As an improvement to the above solution, the lifebuoy is equipped with a drain outlet to drain water accumulated at the installation points of various components.

[0011] As an improvement to the above solution, a protective pad is also included, with the outer frame connected to the protective pad in the direction of the life ring's arc-shaped area.

[0012] This utility model has the following advantages:

[0013] 1. Through the meshing of the first motor drive gear with the inner and outer racks, and the rebound action of the compression spring, the outer and inner baffles extend automatically, thereby clamping the person who has fallen into the water, solving the problem of the person who has fallen into the water being unable to hold onto the lifebuoy and constantly slipping away, and enhancing the stability and fixation of the person who has fallen into the water on the lifebuoy.

[0014] 2. Through the cooperation of the second motor, connecting block, sleeve rod and lead screw, the positions of the outer and inner retaining frames are automatically adjusted according to the distance measured by the sensor to ensure that they can tightly clamp the person in the water, which further improves the fixing effect of the lifebuoy and prevents the person in the water from slipping or getting out during the rescue.

Detailed Implementation

[0023] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0024] Example: An unmanned electric lifebuoy, such as Figures 1-7 As shown, the system includes a lifebuoy 1, a mounting base 2, a first motor 3, a gear 4, an outer baffle 5, an inner baffle 6, an outer rack 7, an inner rack 8, a compression spring 9, a guide rod 10, and an adjustment assembly. A drive assembly is mounted on the lifebuoy 1 to drive it. The lifebuoy 1, which is shaped like a "∪", has mounting base 2 at both ends. The first motor 3 is mounted on the mounting base 2, and the output shaft of the first motor 3 is connected to the gear 4. An outer baffle 5 is slidably connected inside the lifebuoy 1, and an inner baffle 6 is slidably connected inside the outer baffle 5. Inner racks 8 are evenly connected to the inner baffle 6. An outer rack 7 is connected to the outer frame 5, but some teeth are missing at both ends of the outer frame 5. The inner rack 8 is always engaged with the gear 4, and the inner frame 6 will not disengage from the life ring 1. A guide rod 10 is connected inside the outer rack 7. A cavity 1001 is opened inside the inner frame 6. The guide rod 10 is slidably connected inside the cavity 1001. A compression spring 9 is sleeved on the guide rod 10. One end of the compression spring 9 is connected to the outer frame 5, and the other end is connected to the inner frame 6. Under normal conditions, the compression spring 9 is in a compressed state. An adjustment component is provided inside the life ring 1 to adjust the position of the mounting base 2.

[0025] like Figure 6 and Figure 7As shown, the adjustment assembly includes a second motor 11, a connecting block 12, a sleeve rod 1301, a lead screw 13, and a sensor 14. The second motor 11 is installed inside the life ring 1. The lead screw 13 is connected to the output shaft of the second motor 11. The connecting block 12 is threaded onto the lead screw 13. The sleeve rod 1301 is connected to the connecting block 12. The sleeve rod 1301 is slidably connected to the inner frame 6 and passes through the inner frame 6. The guide rod 10 is slidably connected to the sleeve rod 1301. The sensor 14 is installed on the outer frame 5 facing the arc-shaped area of ​​the life ring 1. The sensor 14 is wiredly connected to the second motor 11.

[0026] After locating the person in the water, rescuers place lifebuoy 1 in the water and control it to be close to the person, ensuring the opening of the U-shaped lifebuoy 1 faces the person. Even if the person is unconscious, their instinct to call for help will cause them to immediately climb onto lifebuoy 1 and approach the curved section in the middle. Because the lifebuoy 1 is currently unmanned and electrically powered, the person in the water will encounter resistance while moving it. To hold onto lifebuoy 1, the first motor 3 is activated. The gear 4 connected to the first motor 3 engages with the internal rack 8, pushing out the inner stop. The inner frame 6 pushes the outer frame 5 to slide on the life ring 1. Since the outer frame 5 is not connected to the outer rack 7 at both ends and is blocked by the gear 4, it cannot move outwards. Therefore, after the inner frame 6 moves a certain distance, the gear 4 meshes with the outer rack 7, and then the outer frame 5 and inner frame 6 move smoothly. The internally connected guide rod 10 also moves smoothly until the gear 4 disengages from the outer rack 7. The outer frame 5 is no longer resisted by the gear 4, and the compressed spring 9 rebounds, quickly pushing the outer frame 5 outwards. The guide rod 10 then moves with the outer frame 5. The outer baffles 5 and inner baffles 6 on both sides extend towards the center, preventing the person in the water from drifting backward. Sensor 14 extends outward along with the outer baffles 5, measuring the distance to the person in the water and then sending a signal to the second motor 11. The second motor 11 drives the lead screw 13 to rotate, thereby moving the connecting block 12, bringing the outer baffles 5 and inner baffles 6 closer to the person in the water. Together with the lifebuoy 1, they clamp the person in the water. Under the influence of buoyancy, the person's body rises to the surface, while the outer baffles 5 and inner baffles 6 on both sides press against the body, creating a certain resistance. With force, the person who fell into the water moves towards the shore with the lifebuoy 1. After the rescue is completed, the first motor 3 and the second motor 11 are turned on in sequence. The second motor 11 drives the connecting block 12 to slide and reset through the lead screw 13. The outer frame 5 is manually pushed, and the guide rod 10 slides along the cavity 1001. The compression spring 9 is compressed. After the outer frame 5 and the inner frame 6 overlap, the first motor 3 drives the gear 4 to rotate in the opposite direction. The gear 4 drives the inner frame 6 to slide and reset through the inner rack 8. At the same time, the gear 4 also meshes with the outer rack 7. Finally, the inner frame 6 and the outer frame 5 are reset.

[0027] like Figure 2 As shown, it also includes a protective shell 15, which is rotatably connected to the life ring 1 to cover the adjustment assembly.

[0028] The protective shell 15 can protect the person who falls into the water. When the person grabs the lifebuoy 1, they will not grab the first motor 3 and the second motor 11, thus ensuring the safety of the person who falls into the water.

[0029] like Figure 2 As shown, it also includes a warning light 16, which is installed at the end of the outer frame 5.

[0030] Warning light 16 can alert rescuers of a person in the water in poor visibility conditions, making it easier to locate the lifebuoy 1.

[0031] like Figure 2 As shown, a drain outlet 17 is provided inside the life ring 1 to drain the water accumulated at the installation points of various components.

[0032] After the lifebuoy 1 is placed on the shore, the drain outlet 17 can drain the water in the lifebuoy 1 in a timely manner, reducing the contact time between the components and the water, thereby protecting the surface properties of each component.

[0033] like Figure 5 As shown, it also includes a protective pad 18, and the outer frame 5 is connected to the protective pad 18 in the direction of the arc-shaped area of ​​the life ring 1.

[0034] When the back of the person who has fallen into the water comes into contact with the protective pad 18, the soft protective pad 18 is compressed, which can protect the patient. At the same time, the outer frame 5 moves the same distance, making the clamping effect on the person who has fallen into the water more obvious.

[0035] After locating the person in the water, rescuers place a lifebuoy 1, which is shaped like a "∪", into the water and maneuver it close to the person, ensuring that the opening of the lifebuoy 1 faces the person. The person, instinctively seeking help, will climb onto the lifebuoy 1, especially near the curved section in the middle. At this point, the first motor 3 is activated, and the gear 4 on its output shaft engages with the inner rack 8 on the inner frame 6, pushing the inner frame 6 and the connected outer frame 5 to slide on the lifebuoy 1. Because the outer frame 5 is not connected to the outer rack 7 at both ends and is blocked by the gear 4, after the inner frame 6 moves a certain distance, the gear 4 engages with the outer rack 7 on the outer frame 5, and the two move smoothly until the gear 4 disengages from the outer rack 7. At this point, the compressed spring 9 rebounds, quickly pushing out the outer frame 5. The guide rod 10 moves accordingly, causing the outer frames 5 and the inner frame 6 on both sides to extend towards the middle, preventing the person from drifting backward. Simultaneously, the sensor 14 on the outer retaining frame 5 measures the distance to the person in the water and sends a signal to the second motor 11, driving the lead screw 13 to rotate. Through the sliding of the connecting block 12 and the sleeve 1301, the positions of the outer retaining frame 5 and the inner retaining frame 6 are adjusted, making them more tightly clamp the person in the water, cooperating with the lifebuoy 1 to clamp the person. Under the action of buoyancy, the person's body floats up, and the outer retaining frames 5 and the inner retaining frames 6 on both sides provide resistance, allowing the person to move towards the shore with the lifebuoy 1. After the rescue is completed, the first motor 3 and the second motor 11 are started in sequence. The second motor 11 drives the connecting block 12 to reset through the lead screw 13, and the outer retaining frame 5 is manually pushed back, the compression spring 9 is compressed again, and then the first motor 3 rotates in the opposite direction. The gear 4 drives the inner retaining frame 6 and the outer retaining frame 5 to reset through the inner rack 8 and the outer rack 7. In addition, the protective shell 15 protects the person falling into the water from motor damage, the warning light 16 alerts rescuers when visibility is poor, the drain outlet 17 promptly drains accumulated water, and the protective pad 18 enhances the gripping effect on the person falling into the water and provides comfortable protection.
