Technical Field

[0001] This utility model relates to the field of lifesaving equipment technology, and in particular to a lifesaving device. Background Technology

[0002] Lifebuoys are a common type of water rescue equipment with a wide range of applications, including shipping, flood relief, and water operations, playing a vital role in protecting lives. With rapid urban development, lifebuoys are also playing an important role in low-lying areas prone to flooding, such as sunken tunnels and underground parking garages.

[0003] To reduce drowning casualties during floods, a certain number of lifebuoys are provided in low-lying areas prone to flooding, such as sunken tunnels and underground parking garages. To prevent theft, management personnel often securely fasten the lifebuoys to the walls of these areas, reducing the loss rate. However, this method makes it difficult for people who fall into the water to retrieve the lifebuoys, hindering their self-rescue efforts. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a life-saving device that can be released into the water during flooding, thereby reducing the difficulty for people who have fallen into the water to obtain a life ring and facilitating their self-rescue.

[0005] This utility model discloses a lifesaving device, including a life ring. The life ring has a buoyancy cavity and a mounting cavity formed within it, the buoyancy cavity and the mounting cavity being isolated from each other. A water level detector and a controller are disposed within the mounting cavity. The life ring also has an electronic lock electrically connected to the controller, the electronic lock being used to lock with a fixing component installed on a wall. A detection hole is provided on the side wall of the mounting cavity, one end of the water level detector passing through the detection hole to sense the external water level. The controller receives the detection information from the water level detector to control the electronic lock to release its lock from the fixing component.

[0006] Optionally, the rescue device further includes a safety ladder, which includes two ropes connected to the lifebuoy and a plurality of support rods disposed between the two ropes.

[0007] Optionally, the rescue device further includes a light-emitting component, which includes a light emitter and a light-emitting strip. The light emitter is disposed in the mounting cavity, and the light-emitting strip is intertwined with the rope. The light-emitting side of the light emitter corresponds to one end of the light-emitting strip.

[0008] Optionally, a counterweight is provided at the end of the safety ladder away from the lifebuoy.

[0009] Optionally, the mounting cavity has an opening, and a mounting cover is connected to the opening, with the mounting cover and the mounting cavity being sealed together.

[0010] Optionally, the buoyancy cavity is provided with a receiving groove, and the electronic lock is disposed in the receiving groove. The electronic lock includes a lock body electrically connected to the controller and a pin connected to the lock body. The pin can extend or retract from the lock body.

[0011] Optionally, the mounting cover is provided with a first through hole and a second through hole, the first through hole is used to pass through the wire connecting the lock body, the second through hole is used to pass through the light strip, and the first through hole and the second through hole are filled with sealant.

[0012] Optionally, the mounting cover and the mounting cavity are connected by fasteners.

[0013] Optionally, a storage battery is also provided inside the mounting cavity, and the water level detector, the controller, the electronic lock, and the light-emitting component are electrically connected to the storage battery.

[0014] Optionally, the mounting cavity occupies less than or equal to 1 / 8 of the total volume of the lifebuoy.

[0015] Compared with existing technologies, the beneficial effects of the lifesaving device provided by this utility model embodiment are as follows: By dividing the interior of the lifebuoy into mutually isolated buoyancy chambers and installation chambers, this structural design ensures that the buoyancy performance of the lifebuoy is not affected, while providing suitable installation space for electronic components such as water level detectors, controllers, and electronic locks. This allows for a reasonable layout of each component without interference, ensuring the stable operation of the overall lifesaving device. Simultaneously, this structural design facilitates the maintenance and replacement of electronic components, improving the maintainability of the lifesaving device. Furthermore, by setting the lifebuoy with an electronic lock and fasteners, under normal circumstances, the electronic lock firmly fixes the lifebuoy to the wall, effectively preventing theft and addressing the anti-theft requirements of traditional fixing methods. When flooding occurs and the water level reaches a certain height, the water level detector detects the water level information and transmits it to the controller. The controller then unlocks the electronic lock, allowing the lifebuoy to detach smoothly from the wall. The person in the water can then easily retrieve the lifebuoy for self-rescue, perfectly balancing the seemingly contradictory needs of anti-theft and self-rescue, thus improving the practicality and reliability of the lifesaving device in actual applications.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a lifesaving device 100, including a life ring 110. The life ring 110 has a buoyancy cavity 112 and a mounting cavity 114 formed within it, which are isolated from each other. A water level detector 120 and a controller 130 are disposed within the mounting cavity 114. An electronic lock 140, electrically connected to the controller 130, is also disposed on the life ring 110. The electronic lock 140 is used to lock with a fixing member 105 disposed on a wall. A detection hole 1142 is opened on the side wall of the mounting cavity 114, and one end of the water level detector 120 passes through the detection hole 1142 to allow the water level detector 120 to sense the external water level. The controller 130 is used to receive the detection information from the water level detector 120 to control the electronic lock 140 to release its lock from the fixing member 105.

[0026] Specifically, a water level detector 120 and a controller 130 are installed inside the mounting cavity 114. One end of the water level detector 120 extends through a detection hole 1142 opened on the side wall of the mounting cavity 114 to sense the external water level. When flooding occurs, the water level detector 120 can detect the water level information, so that the controller 130 can control the electronic lock 140 to release from the fixing member 105, allowing the lifebuoy 110 to detach from the wall for people who have fallen into the water to retrieve.

[0027] The lifesaving device 100 provided in this embodiment divides the interior of the lifebuoy 110 into a mutually isolated buoyancy cavity 112 and a mounting cavity 114. This structural design ensures that the buoyancy performance of the lifebuoy 110 is not affected, while also providing suitable installation space for electronic components such as the water level detector 120, controller 130, and electronic lock 140. This allows for a reasonable layout of each component without interference, ensuring the stable operation of the overall function of the lifesaving device 100. Simultaneously, this structural design facilitates the maintenance and replacement of electronic components, improving the maintainability of the lifesaving device 100. Furthermore, by configuring the lifebuoy 110 with a structure secured by the electronic lock 140 and the fixing member 105, under normal circumstances, the electronic lock 140 firmly fixes the lifebuoy 110 to the wall, effectively preventing theft and addressing the anti-theft requirements of traditional fixing methods. When flooding occurs and the water level reaches a certain height, the water level detector 120 detects the water level information and transmits it to the controller 130. The controller 130 controls the electronic lock 140 to unlock, allowing the lifebuoy 110 to detach smoothly from the wall. People who have fallen into the water can easily obtain the lifebuoy 110 for self-rescue, which improves the practicality and reliability of the rescue device 100 in actual applications.

[0028] like Figure 4 As shown, the rescue device 100 also includes a safety ladder 150, which includes two ropes 152 connected to the life ring 110, and a plurality of support rods 154 disposed between the two ropes 152.

[0029] Specifically, the safety ladder 150, combined with the lifebuoy 110, forms a more complete rescue system. Compared to a single lifebuoy 110, this combined rescue device 100 can better meet the needs of different scenarios and individuals, providing more comprehensive rescue protection for those who fall into the water. In practical applications, it can provide support for individuals, preventing them from relying solely on the lifebuoy 110 and allowing other parts of the body to exert force. For individuals with weaker physical strength or who are not good swimmers, the presence of the safety ladder 150 greatly increases their chances of survival in emergency situations.

[0030] In an optional embodiment of this application, the lifesaving device 100 further includes a light-emitting component, which includes a light emitter and a light-emitting strip. The light emitter is disposed in the mounting cavity, and the light-emitting strip is intertwined with the rope 152. The light-emitting side of the light emitter corresponds to one end of the light-emitting strip.

[0031] Specifically, in flooded environments at night or in dimly lit conditions, people who have fallen into the water often have difficulty seeing their surroundings and the location of the rescue device 100. The luminous component allows the rescue device 100 to emit a bright light in the dark, significantly improving its visibility. People in the water can quickly locate the rescue device 100 based on the light emitted by the luminous component, and promptly obtain the lifebuoy 110 and safety ladder 150 for self-rescue, avoiding missing the best escape opportunity due to the inability to find the rescue device 100, greatly improving the rescue efficiency of the rescue device 100 in complex environments. In addition to helping people in the water find the rescue device 100, the light emitted by the luminous component also facilitates rescuers in quickly locating the rescue device 100 during rescue operations. In large flooded areas, rescuers can quickly locate trapped individuals using the light emitted by the luminous component, improving the accuracy and efficiency of rescue operations and providing strong support for the timely rescue of trapped individuals.

[0032] The light strip can be made of optical fiber, and the light emitter can be a laser generator. The light emitted by the laser generator propagates through one end of the optical fiber, and the color of the light emitted by the laser is the final color of the light strip, such as red or green.

[0033] In an optional embodiment of this application, a counterweight is provided at the end of the safety ladder 150 away from the lifebuoy 110.

[0034] Specifically, in turbulent or complex flooded environments, if the safety ladder 150 lacks a counterweight, the rope 152 may float, curl, or become tangled due to the impact of the water flow and buoyancy, preventing a person falling into the water from climbing properly. The counterweight overcomes these problems, allowing the safety ladder 150 to sink quickly and maintain a vertical position after falling into the water, providing stable and reliable support for the person in the water and improving the safety and reliability of the rescue device 100 in actual use.

[0035] like Figure 2 As shown, the mounting cavity 114 has an opening 1144, and a mounting cover 160 is connected to the opening 1144, and the mounting cover 160 is sealed to the mounting cavity 114.

[0036] Specifically, since the mounting cavity 114 houses electronic components with high environmental requirements, intrusion of water or dust into these components may cause short circuits, damage, or other malfunctions, rendering the life-saving device 100 inoperable. The sealed connection between the mounting cover 160 and the mounting cavity 114 effectively prevents external water and dust from entering the mounting cavity 114, providing a relatively dry and clean working environment for the electronic components, protecting their normal operation, extending the service life of the life-saving device 100, and ensuring its reliable function in critical moments. Furthermore, the mounting cover 160 facilitates maintenance and repair of the electronic components within the mounting cavity 114. When inspection, replacement, or repair of electronic components is required, the mounting cover 160 can be opened for easy access to each component and corresponding operations.

[0037] like Figure 1 and Figure 2 As shown, a receiving groove 1122 is provided on the buoyancy cavity 112, and an electronic lock 140 is disposed in the receiving groove 1122. The electronic lock 140 includes a lock body 142 electrically connected to the controller 130, and a pin 144 connected to the lock body 142. The pin 144 can extend or retract from the lock body 142.

[0038] Specifically, the electronic lock 140 adopts a structure of lock body 142 and pin 144, which can achieve a reliable locking function. Under normal circumstances, the pin 144 extends and closely cooperates with the fixing part 105 on the wall, firmly fixing the lifebuoy 110 to the wall and effectively preventing the lifebuoy 110 from being stolen. When flooding occurs, when the controller 130 issues an unlocking command, the pin 144 can quickly retract, allowing the lifebuoy 110 to smoothly detach from the wall and be used by people who have fallen into the water. This locking and unlocking method is simple and reliable to operate, and can meet the needs of the life-saving device 100 in different usage scenarios. In addition, the electronic lock 140 is set in the receiving groove 1122, which can prevent the electronic lock 140 from protruding outward, which is beneficial to the protection of the electronic lock 140, and can also make the electronic lock 140 independent outside the mounting cavity 114, which is convenient for cooperation with the fixing part 105. The electronic lock 140 can be a conventional electronic lock 140 with a certain waterproof rating, and this application embodiment does not make specific limitations on this.

[0039] In an optional embodiment of this application, the mounting cover 160 is provided with a first through hole and a second through hole. The first through hole is used to pass through the wire connecting the lock body 142, and the second through hole is used to pass through the light-emitting strip. The first through hole and the second through hole are filled with sealant.

[0040] Specifically, the first and second vias provide channels for the wires and light-emitting strips to pass through, ensuring the circuit connection between the electronic lock 140 and the controller 130, as well as the light transmission between the emitter and the light-emitting strip. Through a reasonable via design, the wires and light-emitting strips can be neatly arranged at the mounting cover 160, avoiding problems such as tangling and compression, and ensuring the normal operation of the electrical and optical systems inside the life-saving device 100. Both the unlocking control of the electronic lock 140 and the light-emitting function of the light-emitting component can be stably connected and transmitted through the first and second vias. Furthermore, the sealant allows the mounting cover 160 to maintain good sealing performance while allowing the wires and light-emitting strips to pass through, providing comprehensive protection for the electronic components within the mounting cavity 114, preventing damage to electronic components due to poor sealing of the first or second via, and ensuring the reliability and stability of the life-saving device 100.

[0041] In an optional embodiment of this application, the mounting cover 160 and the mounting cavity 114 are connected by fasteners.

[0042] Specifically, fasteners can take various forms, such as screws and bolts. Using fasteners to connect the mounting cover 160 and the mounting cavity 114 ensures a firm connection between the mounting cover 160 and the mounting cavity 114. During the use of the life-saving device 100, the mounting cover 160 will not easily fall off, thus ensuring the protective function of the mounting cover 160 for the electronic components inside the mounting cavity 114.

[0043] like Figure 2 As shown, a storage battery 170 is also installed in the mounting cavity 114, and the water level detector 120, controller 130, electronic lock 140 and light-emitting components are electrically connected to the storage battery 170.

[0044] Specifically, when the life-saving device 100 is in its normal storage state, the battery 170 is in a charging state. In the event of flooding, the water level detector 120 detects the water level information and transmits it to the controller 130, triggering a series of actions such as unlocking the electronic lock 140 and illuminating the light-emitting component. The battery 170 provides the necessary power to these electronic components, ensuring the life-saving device 100 can function normally. By placing the battery 170 inside the mounting cavity 114, the internal space of the life ring 110 can be utilized efficiently, and a relatively safe and stable storage environment can be provided for the battery 170, preventing interference and damage from external environmental factors. Furthermore, in emergencies such as flooding, power supply interruptions often occur, rendering traditional externally powered devices unable to function properly. However, the life-saving device 100, relying on its own battery 170, can ensure the normal operation of components such as the water level detector 120, controller 130, electronic lock 140, and light-emitting component, ensuring that the life-saving device 100 can function effectively in critical moments, providing timely and effective rescue for those who have fallen into the water.

[0045] In an optional embodiment of this application, the mounting cavity 114 occupies less than or equal to 1 / 8 of the total volume of the lifebuoy 110.

[0046] Specifically, the proportion of the mounting cavity 114 to the total volume of the lifebuoy 110 is controlled to be less than or equal to 1 / 8, thus optimizing the use of the internal space of the lifebuoy 110. While ensuring the normal installation of various components within the mounting cavity 114, it also ensures the buoyancy of the lifebuoy 110 itself, providing stable support for people who fall into the water.

[0047] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
