Description

Technical Field

[0001] This utility model relates to the field of rescue devices, specifically a throwing anti-drowning and life-saving device. Background Technology

[0002] In emergency rescue, especially water rescue, throwable rescue equipment has become a commonly used tool for rescuers due to its rapid deployment and ease of operation. Currently available throwable rescue equipment mainly consists of a buoyancy device, a connecting rope, and a storage device. The buoyancy device is typically made of lightweight materials and filled with gas or foam to ensure sufficient buoyancy to support the person in the water; the connecting rope is used to connect the buoyancy device to the rescuer or a fixed point; and the storage device is responsible for storing the rope when not in use, maintaining the equipment's compactness and portability.

[0003] However, while existing throwable rescue equipment meets rescue needs to some extent, it still has some shortcomings. For example, a rope throwing device for fire rescue published in CN211835861U has a complex rope storage device design, making it inconvenient to operate. Furthermore, after prolonged use, the rope is prone to tangling and jamming, affecting rescue efficiency. In addition, the buoyancy device in this patent has an unreasonable shape design, making it easy for a person in the water to slip when grabbing it, reducing the success rate of the rescue.

[0004] In addition, a natural water rescue device with publication number CN204895810U, while solving some storage and retrieval problems, has an unstable ground mounting design that makes it prone to tipping over during rescue operations, posing a safety hazard. Furthermore, the rope storage device in this patent lacks sufficient support during rotation, resulting in unstable rotation and further affecting rescue effectiveness. Utility Model Content

[0005] This utility model proposes an improved throwable lifesaving device, which aims to solve problems such as inconvenient rope storage, difficulty in grasping the buoyancy device, and instability of the ground fixing frame.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a throwing anti-drowning and life-saving device, comprising:

[0007] The buoyancy device has an integrated cavity inside and a connecting buckle on the outside, with a rope attached to the connecting buckle;

[0008] A rope, with one end connected to a buoyancy device and the other end connected to a rope storage device;

[0009] The rope storage device consists of a rope storage cylinder as its main body. A horizontally positioned main rotating shaft is fixed inside the cylinder. Openings on both sides of the cylinder allow the shaft end to extend. End caps are fitted to both openings, and a second bearing seat is mounted on the side of each end cap. A frame plate is mounted on the side of the second bearing seat. A rotatable transmission bearing is mounted inside one of the frame plates. One end of the transmission bearing is rotatably connected to the second bearing seat, and the other end is rotatably connected to a first bearing seat outside the frame plate on that side. A rocker arm is connected to the first bearing seat via a coupling. To store the rope in the rope storage cylinder, the rocker arm is turned clockwise. A rocker arm is connected to a shaft seat 1 via a transmission bearing, which is rotatably connected to a shaft seat 2. The main rotating shaft connected to the end of the shaft seat 2 rotates accordingly, and the rope storage cylinder, which is integrally connected to the main rotating shaft, rotates clockwise and winds the rope. When it is necessary to release the rope from the rope storage cylinder, the rocker arm is rocked counterclockwise. The shaft seat 1 connected to the rocker arm is rotatably connected to the shaft seat 2 via a transmission bearing, and the main rotating shaft connected to the end of the shaft seat 2 rotates accordingly. The rope storage cylinder, which is integrally connected to the main rotating shaft, rotates counterclockwise and winds the rope. A ground fixing frame can be installed below the rope storage device.

[0010] Ground-mounted brackets are used to secure rope storage devices and provide support for the stable use of ropes. The ground-mounted brackets are connected to the ground via support legs with fixed cones at the bottom.

[0011] Preferably, the cavity is filled with gas or lightweight foam material to enhance buoyancy.

[0012] Preferably, the buoyancy device is spherical, and its outer surface is provided with anti-slip texture to increase the friction when a person falls into the water grabs it.

[0013] Preferably, a hand-held rope loop is integrally connected to the rope.

[0014] Preferably, both the rope storage tube and the end cap have openings in the middle, which are used for the shaft end of the main rotating shaft to extend out.

[0015] Preferably, the end cap is provided with a limiting cap, the rope storage tube has a ring of threaded holes at the opening, and the limiting cap has a ring of through holes at the corresponding position. The specifications of the through holes are the same as those of the threaded holes. The end cap is assembled into the threaded holes by screws passing through the through holes, thereby achieving assembly with the rope storage tube.

[0016] Preferably, the frame plate is provided with a bearing seat three, and the end cover is provided with a secondary drive shaft that matches the bearing seat three. When the rope storage cylinder rotates with the main rotating shaft, the secondary drive shaft rotates accordingly, providing support for the rope storage cylinder and ensuring the stability of the rotation.

[0017] Preferably, the bottom of the frame is provided with a plug rod, and the ground fixing frame is provided with a matching slot. The rope storage device is assembled by inserting the plug rod into the slot to achieve assembly with the ground fixing frame.

[0018] Preferably, the bottom of the ground fixing frame is a rotating seat, the rotating disk is rotatably assembled in the matching rotating seat, and the bottom of the rotating seat is connected to three support legs.

[0019] Compared with the prior art, the advantages of this utility model are: (1) Convenient rope storage: By shaking the rocker arm to drive the rope storage cylinder to rotate, the rope can be quickly stored and released, avoiding problems such as rope entanglement and jamming, and improving rescue efficiency; (2) Stable buoyancy device: The buoyancy device adopts a spherical design and has anti-slip texture on the outer surface, which increases the friction when the person in the water grabs it, reduces the risk of slipping, and improves the success rate of rescue; (3) Stable and reliable ground fixing frame: The ground fixing frame is connected to the ground through the support legs with fixed cones at the bottom, providing good stability; at the same time, the rope storage device is assembled with the slot on the ground fixing frame through the insertion rod, which further enhances the overall stability and avoids safety hazards such as tipping; (4) Stable rotation support: During the rotation of the rope storage cylinder, the auxiliary drive shaft and the bearing seat on the frame plate cooperate to provide additional support force, ensuring the smoothness and reliability of rotation.

Example

[0057] like Figures 1 to 6 As shown, this embodiment is a throwable drowning prevention and rescue device, mainly composed of key components such as a buoyancy device 1, a rope 2, a rope storage device 3, and a ground fixing frame 4. Its design aims to quickly and effectively throw the buoyancy device 1 to the vicinity of the person in the water, providing immediate buoyancy support, and then use the rope 2 for traction or retrieval.

[0058] Detailed Explanation of Work Methods:

[0059] I. Preparation Stage

[0060] Ensure that the buoyancy device 1 is filled with sufficient gas or lightweight foam material to maintain its buoyancy. The outer surface of the buoyancy device 1 should be kept clean so that it is easy for the person in the water to grab onto. Inspect the rope 2 for damage, wear, or breakage. The rope 2 should be wound around the rope storage device 3 with a certain degree of slack for easy release during throwing. Confirm that all components of the rope storage device 3 are securely connected and rotate freely. Shake the rocker arm 302 to check that the rope 2 can be smoothly released and retrieved from the rope storage cylinder 310. Place the ground fixing frame 4 in a position easily accessible to the rescuer and secure it firmly to the ground using the fixing cone 405. Adjust the rotating disc 403 and the rotating base 402 so that the rope storage device 3 faces the person in the water.

[0061] II. Throwing Phase

[0062] The rescuer, holding the rope loop 201 of rope 2, throws the buoyancy device 1 towards the vicinity of the person in the water. When throwing, pay attention to adjusting the throwing angle and force to ensure that the buoyancy device 1 accurately reaches the target location.

[0063] III. Buoyancy Support Stage

[0064] The person in the water grabs onto buoyancy device 1 and uses the buoyancy provided by buoyancy device 1 to stay on the surface of the water. Rescuers can maintain contact with the person in the water via rope 2, providing necessary guidance and comfort.

[0065] IV. Traction or Recovery Phase

[0066] If the person in the water is able to swim to shore on their own or the rescuer can approach them, the rescuer can slowly pull the hand rope loop 201 to pull the buoyancy device 1 and the person in the water to a safe area via the rope 2. If the person in the water cannot move on their own or the rescuer cannot approach them, the rescuer can use the rope storage device 3 to retrieve the rope. The rescuer cranks the lever 302 to rotate the rope storage cylinder 310 counterclockwise, gradually retrieving the rope 2 and the buoyancy device 1 to the vicinity of the ground-based fixed frame 4.

[0067] V. Conclusion

[0068] After the rescue is completed, detach the buoyancy device 1 from the rope 2, inspect and clean all components. Rewrap the rope 2 around the rope storage device 3 and store it properly. Example

[0069] like Figures 1 to 6 As shown, this embodiment provides a basic throwable rescue device. The buoyancy device 1 is made of high-strength waterproof material and filled with high-pressure gas to ensure sufficient buoyancy. The surface of the buoyancy device 1 has anti-slip textures for easy grabbing by a person falling into the water. The buoyancy device 1 is connected to one end of the rope 2 via a connecting buckle 102. The rope 2 is made of high-strength nylon with a moderate diameter, ensuring both strength and ease of operation.

The rope 2 is equipped with a handheld rope loop 201 for easy gripping by the rescuer. The rope storage device 3 consists of the rope storage cylinder 310, the rocker arm 302, the first shaft seat 301, the second shaft seat 304, the transmission bearing 303, the end cap 307, and the frame plate 312. The rope storage cylinder 310 is connected to the first shaft seat 301 and the second shaft seat 304 via a main rotating shaft 309 to achieve rotation. The rocker arm 302 is connected to the transmission bearing 303 via a coupling, driving the rope storage cylinder 310 to rotate. The frame plate 312 supports the entire device and is equipped with a plug rod 311 connected to the ground fixing frame 4. The ground fixing frame 4 consists of a slot 401, a rotating seat 402, a rotating disk 403, support legs 404, and a fixing cone 405. The slot 401 engages with the plug rod 311 of the rope storage device 3 for fixation. The rotating seat 402 and the rotating disk 403 cooperate to allow the ground fixing frame 4 to adjust its direction within a certain range. The support legs 404 are inserted into the ground via the fixing cone 405 to ensure the stability of the entire device. Example

The rope 2 adopts a telescopic design with a built-in spring mechanism, allowing the rope to automatically extend during throwing to adapt to different rescue distances. An emergency braking device is also added to the rope 2, allowing rescuers to quickly operate it to stop the rope deployment. The rope storage device 3 is equipped with an electric drive system, allowing remote control of the rope's deployment and retraction speeds, improving rescue efficiency. Additionally, the rope storage device 3 includes a counter to record the length of the deployed rope, facilitating rescuers' assessment of rescue progress. Example

[0071] like Figures 1 to 6 As shown, this embodiment provides an intelligent throwable rescue device. Building upon Embodiment 4, it further enhances intelligent functionality. The buoyancy device 1 incorporates a GPS positioning system and a wireless communication module, enabling it to send location information to the rescue center in real time, facilitating rapid location by the rescue team. Simultaneously, the buoyancy device 1 is equipped with an automatic inflation device, which automatically inflates the buoyancy device when insufficient buoyancy is detected.

A vibration sensor is also added to the rope 2; when a person in the water grabs the rope, the sensor is triggered, sending a signal to the rescuer. The rope storage device 3 connects to a smartphone or tablet, allowing rescuers to view the rope status, buoyancy device location, and other information in real time via an application. Furthermore, the rope storage device 3 includes an automatic alarm system, which automatically sends an alarm message to the rescue center when an abnormality is detected in the rope or the buoyancy device is lost.
