Description

Technical Field

[0001] This utility model belongs to the field of emergency rescue equipment, specifically relating to a device that can provide a batch of life-saving devices instantly for water rescue. Background Technology

[0002] Inflatable lifesaving devices (such as self-inflating life rings and life belts) are widely used due to their portability and rapid response. They are characterized by outstanding portability, adequate buoyancy, and strong environmental adaptability. For example, when deflated, they can be folded into the size of a belt or wallet for easy carrying or storage in vehicles or boats. Most products provide buoyancy supporting approximately 80 kg of body weight, meeting the needs of single-person floating. They have a wide operating temperature range (-30℃ to 65℃), suitable for various climatic conditions.

[0003] However, inflatable rescue devices, when stored inflated, take up a significant amount of space. If punctured by sharp objects or subjected to prolonged wear, they may become instantly inoperable, drastically reducing safety. If stored undisturbed, they suffer from slow inflation rates and can only inflate one device at a time during emergency rescues. Currently available rapid-inflation rescue devices typically only allow for the rapid inflation of one device at a time and require periodic replacement of parts, resulting in high long-term operating costs and making them unsuitable for emergency scenarios requiring the rapid deployment of multiple inflatable rescue devices. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems existing in the prior art and provide a device that can instantly provide a batch of life-saving devices. When needed, it can fill and release multiple (even dozens or hundreds) life-saving devices within 2-5 seconds.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited to the following examples.

[0023] As shown in the figure, this utility model discloses a device for instantly providing batches of life-saving devices for water rescue. It includes a high-pressure gas cylinder, a vertical float, a gas control valve, and inflatable life-saving devices. The high-pressure gas cylinder is connected to the vertical float, and the gas control valve is located at the outlet of the high-pressure gas cylinder. Multiple storage compartments are provided on the outer surface of the vertical float, each containing one or more uninflated inflatable life-saving devices. Each inflatable life-saving device is connected to the outlet of the gas control valve or the outlet of the high-pressure gas cylinder via a venting pipe. The vertical float is equipped with a drone connection device or a water propulsion device.

[0024] In this invention, the high-pressure gas cylinder is connected to the vertical float, preferably by a fixed connection. Specifically, the high-pressure gas cylinder can be located inside the vertical float, particularly in the lower middle part of the vertical float.

[0025] The vertical float in this invention has a columnar structure, specifically a cylindrical structure, a cubic columnar structure, a columnar structure with a triangular cross-section, a columnar structure with a 5-10 polygonal cross-section, etc. A high-pressure gas cylinder is fixedly connected to the center of the vertical float, particularly embedded within its core. Due to the relatively heavy mass of the high-pressure gas cylinder, the vertical float can float vertically in the water, with the high-pressure gas cylinder acting as ballast at the bottom.

[0026] The drone connection device of this invention is a connection device that can be suspended below a drone and can be directly or indirectly connected to the drone. It can be located at the top of a vertical float. Specifically, the drone connection device may include magnets, electromagnets, slots, or gripping rings. Correspondingly, the drone can be equipped with connection mechanisms such as slings and magnets, slings and electromagnets, or slings and grippers, so that the device of this invention can be suspended below the drone when needed.

[0027] In this invention, two water propellers are preferably used. The main body of the water propeller is connected to the outer surface of the vertical float, or the main body of the water propeller is located inside the vertical float. The two water propellers are arranged side by side in the upper middle part of the vertical float. Furthermore, a power source providing power to the water propellers can be installed inside the vertical float. A remote control device can also be installed inside the vertical float to provide precise remote control of the two water propellers, thereby maneuvering the device of this invention to reach the desired location.

[0028] The storage compartment in this invention is used to store undated inflatable lifesaving devices. It can be a recessed grid structure into the vertical float or a grid structure fixed to the outer surface of the vertical float. A protective cover is provided at the opening of a single storage compartment, or an integrated protective cover is provided at the openings of multiple storage compartments. Each storage compartment holds one or more undated inflatable lifesaving devices, preferably one, to prevent multiple inflatable lifesaving devices from becoming entangled or obstructing each other during rapid inflation. The protective cover, whether at the opening of a single storage compartment or an integrated protective cover at the openings of multiple storage compartments, is of an easy-open or easily breakable design to prevent interference with the ejection of the lifesaving device from the storage compartment after inflation. The number of storage compartments can be 3 or more, 5 or more, 10 or more, 20 or more, 50 or more, 100 or more, or 200 or more.

[0029] The storage compartment 51 in this invention can have various grid shapes, such as cubic grids, cuboid grids, cylindrical grids, hexagonal grids, honeycomb grids, etc. The uninflated inflatable life-saving device is very small and can be easily placed inside the storage compartment. When the inflatable life-saving device is inflated, its volume increases and it expands outwards. When it touches the easily openable or easily breakable protective cover, it will not be blocked by the cover but will continue to expand. During the inflation process, it can be ejected from the storage compartment, completing the inflation process outside and forming a complete life-saving device.

[0030] The inflatable lifesaving devices in this equipment include inflatable life rings, inflatable airbags, or inflatable life jackets, with a quick-connect duct connector at the inflation port. Multiple inflatable lifesaving devices can be used, specifically 3, 5, or 8 or more. This equipment is particularly suitable for 10, 20, 50, or even 100, 200, or 500 or more inflatable lifesaving devices. The quick-connect duct connector at the inflation port allows for quick separation of the inflatable lifesaving device from the duct when needed, without affecting the internal air pressure. The inflatable lifesaving devices in this invention can employ a post-inflation protection mechanism at the inflation port to prevent air leakage when external pressure decreases after inflation. Alternatively, a quick-connect duct connector can be used to prevent air leakage from the inflation port after inflation. Each inflatable lifesaving device has its air inlet connected to the air outlet of a separate pipe.

[0031] High-pressure gas cylinders can be filled with various gases such as high-pressure air, nitrogen, helium, and carbon dioxide. High-pressure gas cylinders can be connected to pressure gauges to measure pressure.

[0032] In one embodiment, the ventilation pipeline of this utility model includes a main pipe, a distribution component, and multiple branch pipes. The air inlet of the main pipe is connected to the gas outlet of a high-pressure gas cylinder or a gas control valve. The air inlet of the distribution component is connected to the air outlet of the main pipe. The air inlets of each branch pipe are connected to different air outlets of the distribution component, and the air outlets of each branch pipe are connected to the air inlets of each inflatable life-saving device. A duct hole for the branch pipes to pass through is provided in the storage compartment. The distribution component includes a distribution block, distribution manifold, distribution plate, distribution manifold, or diversion valve that can divide a single airflow into multiple airflows. The number of branch pipes corresponds to the number of inflatable life-saving devices.

[0033] This invention uses a gas control valve to regulate the gas supplied from the high-pressure gas cylinder and ensures that each inflatable life-saving device can be rapidly inflated within 2-5 seconds. The gas control valve may include a cylinder head valve, which is connected to the outlet of the high-pressure gas cylinder for directly opening or closing it. The outlet of the cylinder head valve is connected to the inlet of the ventilation pipeline. The cylinder head valve in this invention refers to a valve located at the head of the high-pressure gas cylinder, used to directly open or close the cylinder. The cylinder head valve can be any existing valve capable of controlling high-pressure gas.

[0034] In one embodiment, the gas control valve includes a bottle head valve and a solenoid valve; the solenoid valve is connected to the bottle head valve and is used to receive external signals and transmit the signals to the bottle head valve to control the opening of the bottle head valve.

[0035] In another design, the gas control valve includes a cylinder head valve and a pressure reducing valve. The pressure reducing valve is located at the outlet of the cylinder head valve and is used to adjust the outlet pressure of the high-pressure gas cylinder (if the pressure is too high) to a pre-set pressure value, preventing the inflatable life-saving device from exploding due to excessive outlet pressure. The inlet of the pressure reducing valve is connected to the outlet of the cylinder head valve. If the high-pressure gas cylinder is filled with a set amount of gas, and the pressure inside the cylinder after a short period of deflation balances with the pressure inside the fully inflated life-saving device without damaging it, then a pressure reducing valve is not required.

[0036] In one design, an emergency lighting device, an alarm device, a positioning device, or a video device is installed at the upper end of the vertical floating body.

[0037] This equipment may further include an emergency lighting device located on the upper part of the vertical float, which is connected to a gas control valve via wiring to provide illumination or positioning for emergency rescue at night or in low light conditions.

[0038] The equipment may further include an alarm device located at the top of the vertical float, which is connected to the gas control valve via a line and provides an alarm to personnel when the gas control valve is activated.

[0039] This equipment may further include a positioning device located on the upper end of the vertical float, which is connected to the gas control valve via a line and provides positioning for the container after the gas control valve is activated, or provides positioning for subsequent rescue.

[0040] This device may further include a video device located on the upper part of the vertical float, which can provide support for remote control or remote communication.

[0041] The device may further include a water immersion sensor mounted on a vertical float, which is connected to a gas control valve.

[0042] This device can be equipped with batteries inside a vertical float to provide power to various devices that require electricity.

[0043] The device can be started manually, with a button at the top of the vertical float to open the gas control valve. When the device is lowered to the desired location on the water surface, the person being rescued presses the button, causing gas to instantly fill each inflatable life-saving device through the vent pipe. Within 2-5 seconds, each inflatable life-saving device is fully inflated and pops out.

[0044] The device of this invention can be started remotely, that is, a control system with remotely controllable gas control valves is installed in the vertical float. When the device is raised to the desired location on the water surface, the remote operator opens the gas control valves, allowing gas to instantly fill each inflatable life-saving device through the vent pipe. Within 2-5 seconds, each inflatable life-saving device is fully inflated and deploys.

[0045] The device of this invention can be started automatically, that is, by using a water immersion sensor as the starting information source. When the device is airlifted by a drone to the required location and placed in the water, the water immersion sensor detects the water immersion and sends a start signal to the gas control valve, causing gas to be instantly injected into each inflatable life-saving device through the vent pipe. Within 2-5 seconds, each inflatable life-saving device is fully inflated and pops out.

[0046] When the gas control valve is activated, the high-pressure gas in the high-pressure cylinder is rapidly supplied through the venting pipe to multiple uninflated inflatable life-saving devices stored in multiple storage compartments. Each inflatable life-saving device is fully inflated within 2-5 seconds and automatically squeezed out of the storage compartment or ejected from the tank under pressure, releasing it around the vertical float. Dozens or even hundreds of devices can be deployed simultaneously, allowing a person in the water to easily retrieve one. Alternatively, a single inflatable life-saving device can be disconnected from its branch pipe via a quick-connect fitting, allowing the person to survive with the aid of the inflatable device. This equipment is particularly suitable for scenarios requiring the rapid deployment of a large number of life-saving devices.

[0047] This invention's device can be remotely deployed by drones and instantly deploy a large number of inflatable life-saving devices. It can also be repositioned by drone if the initial drone drop is inaccurate, or, when a second deployment is needed, the device can be transported to the required location directly using a water propulsion system without requiring drone re-lifting, instantly deploying a large number of inflatable life-saving devices. Even when drones are unavailable, the device can be directly transported to the required location using a water propulsion system for instantaneous deployment of a large number of inflatable life-saving devices.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
