Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water rescue equipment, and in particular to a water rescue device. Background Art
[0002] Drones have become a crucial tool in current water rescue operations due to their rapid arrival capabilities, but they typically carry only a limited number of swim rings. Limited by their payload capacity and storage space, traditional drones can typically only carry one or two sets of pre-inflated or foldable swim rings, making them inadequate for complex rescue scenarios like group drowning. Consumer drones typically have a maximum payload of 2-5kg, while a single pre-inflated swim ring, including the inflator, can weigh 1.5-2kg. Carrying more than three sets significantly reduces the drone's flight time and increases flight risk.
[0003] From the perspective of storage space, the internal or external storage structures of the drone body are mostly flat or streamlined in design. The ring structure of the pre-inflated swimming ring is difficult to stack efficiently and often needs to be hung under the arm, which not only increases air resistance but may also interfere with the propeller.

[0028] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.
[0029] like Figures 1-6 The following describes the water rescue device according to an embodiment of the present application with reference to the accompanying drawings, including:
[0030] Drone 1.
[0031] The swimming ring accommodating block 2 is set on the drone 1.
[0032] The swim ring 3 can be stored in multiple groups. The swim ring accommodating block 2 is provided with a cavity for placing the swim ring 3. The swim ring 3 can be stored in the cavity. The swim ring 3 includes an extruded inflatable block 4 and a bag ring 5. The extruded inflatable block 4 includes a storage block 6, a first bag 7 and a second bag 8.
[0033] The storage block 6 is provided with an inflation port which is communicated with the bag ring 5 . The first bag 7 and the second bag 8 are both arranged inside the storage block 6 . Sodium bicarbonate is provided inside the first bag 7 , and citric acid solution is provided inside the second bag 8 .
[0034] The housing of the swimming ring accommodating block 2 is provided with a squeezing block 9 for squeezing the first bladder 7 and the second bladder 8 .
[0035] The cavity of the swimming ring accommodating block 2 is provided with a pushing device 10 for pushing the storage block 6 .
[0036] Specifically, after the drone 1 arrives at the rescue area and locates the person who has fallen into the water, the control system triggers the propulsion device 10, pushing the storage block 6 in the target cavity toward the exit. During the pushing process, the extrusion block 9 squeezes the first and second bladders 7 and 8 in the storage block 6, rupturing the separating membrane. The two chemical substances mix to produce an acid-base reaction: 3NaHCO3+C6H8O7→3CO2↑+3H2O+C6H5O7Na3, rapidly generating carbon dioxide gas. The gas is then filled into the bladder ring 5 through the one-way valve at the inflation port, causing it to expand and take shape within seconds. After the storage block 6 is completely pushed out of the cavity, it carries the inflated swimming ring with it and falls into the water near the person who has fallen into the water, providing buoyancy support.
[0037] The modular design supports the continuous deployment of multiple groups of swimming rings to meet the needs of group rescue. The compact structure can be folded and stored, greatly increasing the carrying capacity of the drone in a single mission.
[0038] In one embodiment of the present application, the first bladder 7 and the second bladder 8 are closely arranged inside the storage block 6 .
[0039] The fitting arrangement enables the extrusion block 9, such as a rigid pressure plate or elastic protrusion in the cavity, to apply a balanced extrusion force to the two capsules when pushing the storage block 6, thereby ensuring that the first capsule 7 of sodium bicarbonate and the second capsule 8 of citric acid solution rupture synchronously, avoiding the situation where a single capsule ruptures first and the other capsule is not triggered due to uneven force, thereby ensuring a rapid and complete chemical reaction.
[0040] The close fit of the two bags can reduce the overall volume of the storage block 6, making the single accumulator swimming ring 3 more compact in the folded state, and facilitating the stacking and storage of multiple groups of swimming rings in the swimming ring accommodating block 2.
[0041] In one embodiment of the present application, there are two groups of storage blocks 6 and two groups of bag rings 5. One end of the bag ring 5 is an air inlet. The air inlet of the bag ring 5 is connected to the inflation port of one group of storage blocks 6, and the other end is connected to the end face of another group of storage blocks 6.
[0042] In this embodiment, the storage blocks 6 and the bag rings 5 are each arranged in two groups, and the two ends of the bag rings 5 are respectively connected to the inflation port of one group of storage blocks 6 and the end face of the other group of storage blocks 6, forming a symmetrical structure of "double storage blocks 6-double bag rings 5".
[0043] Two-way synchronous inflation: When the sodium bicarbonate solution in the first bladder 7 and the citric acid solution in the second bladder 8 of each storage block 6 are squeezed and ruptured, the generated carbon dioxide gas is simultaneously inflated into the bladder ring 5 through the inflation ports at both ends, causing the two bladder rings 5 to expand synchronously. Compared with single-group inflation, the inflation time is shortened.
[0044] The two-way air inlet design avoids the problem of uneven expansion of the bag ring 5 caused by unilateral inflation, ensuring that a regular ring structure is formed after inflation.
[0045] The two groups of storage blocks 6 can work independently or collaboratively: when the storage block 6 on one side is triggered normally, the single group of inflation can still provide basic buoyancy to ensure single-person rescue.
[0046] When the two groups are triggered synchronously, the total gas production is doubled and the buoyancy is increased, which is suitable for rescue scenarios involving two people or those carrying equipment.
[0047] The two ends of the bag ring 5 are connected to the end faces of the storage block 6 to form a closed mechanical structure. After inflation, the storage blocks 6 at both ends act to disperse the pulling force when the person falls into the water and avoid local tearing of the bag ring 5.
[0048] Compact space and modular expansion: two groups of storage blocks 6 are symmetrically arranged along the circumference of the capsule ring 5, and the annular space is used to achieve lightweight integration of chemical modules.
[0049] In one embodiment of the present application, a slider 11 is provided on the side of the storage block 6, a sliding groove adapted to the slider 11 is provided in the swimming ring accommodating block 2, a triangular block 12 is elastically provided on the outer side of the slider 11, and a clamping block 13 for unidirectionally clamping the triangular block 12 is provided in the swimming ring accommodating block 2.
[0050] The outer side of the slider 11 is elastically connected to the triangular block 12 via a spring, and the inner wall of the storage block is provided with a clamping block 13. When the storage block 6 is pushed into the cavity, the triangular block 12 is squeezed by the clamping block 13 and the spring is compressed. After sliding past the clamping block 13, the spring returns and the triangular block 12 is locked into the clamping slot, achieving one-way locking.
[0051] In one embodiment of the present application, the pushing device 10 includes a transverse drive motor 14, a longitudinal drive motor 15 and an L-shaped block 16, wherein:
[0052] The longitudinal drive motor 15 is arranged inside the cavity of the swim ring holding block 2. The output end of the longitudinal drive motor 15 is connected to the base of the transverse drive motor 14. The output end of the transverse drive motor 14 is connected to the end of the L-shaped block 16. The driving direction of the transverse drive motor 14 is toward the triangular block 12, and the driving direction of the longitudinal drive motor 15 is toward the cavity outlet of the swim ring holding block 2.
[0053] There are two groups of extrusion blocks 9 , and the extrusion ends of the two groups of extrusion blocks 9 face the first bladder 7 and the second bladder 8 respectively.
[0054] When the control system of the UAV 1 sends a delivery command, the lateral drive motor 14 is first started, and drives the L-shaped block 16 to move laterally toward the triangular block 12 through gears or screw transmission.
[0055] The right-angled end of the L-shaped block 16 abuts the inclined surface of the triangular block 12, applying a lateral thrust, forcing the triangular block 12 to compress the spring and retract into the inside of the slider 11, disengaging from the slot of the card block 13, and the storage block 6 slides synchronously with the slider 11 in the slide groove, and then is pushed by the longitudinal drive motor 15. When it moves to the action area of the extrusion block 9: the top extrusion block 9 toward the first capsule 7 and the bottom extrusion block 9 toward the second capsule 8 respectively abut against the two side surfaces of the storage block 6, and the longitudinal displacement of the storage block 6 is used to generate relative extrusion force.
[0056] The sodium bicarbonate in the first capsule 7 and the citric acid solution in the second capsule 8 are fitted together and are squeezed synchronously by the two sets of squeezing blocks 9. The easily breakable film in the middle breaks, and the two chemicals mix, triggering an acid-base reaction to generate CO2 gas.
[0057] In one embodiment of the present application, a magnetic block is provided on the outside of the storage block 6, and an electromagnetic lock arranged in an array is provided inside the swimming ring receiving block 2.
[0058] Specifically, when the magnetic block on the outside of the storage block 6 and the electromagnetic lock inside the swimming ring accommodating block 2 are energized, the storage block 6 is adsorbed and fixed. After receiving the delivery instruction, the electromagnetic lock is de-energized to release the magnetic block. The storage block 6 is unlocked and pushed out of the cavity under the action of the pushing device 10, and the squeezing triggers inflation. The electromagnetic lock array can independently control the release of multiple groups of storage blocks 6 in sequence, thereby realizing the precise delivery of single or multiple groups of swimming rings.
[0059] In one embodiment of the present application, the outer ring of the drone 1 is provided with a floating ring 17 .
[0060] Specifically, the drone 1 adopts a multi-rotor structure, with a fuselage made of carbon fiber composite material and a waterproof coating on the surface. The outer ring is surrounded by a closed-cell EVA foam float ring 17, which has sufficient buoyancy to ensure that the entire drone floats after falling into the water.
[0061] In one embodiment of the present application, multiple groups of cameras 18 are provided on the outer ring of the drone 1 .
[0062] Specifically, multiple groups of waterproof cameras 18 are arranged around the fuselage, supporting wide-angle shooting and infrared night vision, and a built-in AI image recognition module that can detect targets in the water in real time.
[0063] In one embodiment of the present application, a propeller assembly 19 is provided on the bottom surface of the drone 1 , and the propeller assembly 19 is provided on the bottom surface of the drone 1 through a rotating assembly.
[0064] Specifically, the bottom propeller assembly 19 is connected through a rotatable pan-tilt head and driven by a waterproof motor. It can adjust the thrust direction according to the water flow state and adapt to different water environments.
[0065] In actual use, 1. UAV 1 reconnaissance and positioning.
[0066] Drone 1, equipped with multiple retractable swimming rings 3, flew to the rescue area. Waterproof cameras 18 circumferentially positioned around the drone, using infrared night vision and AI image recognition, scanned the water in real time to accurately locate the victim. The propeller assembly 19 on the underside adjusted thrust direction via a rotating gimbal, ensuring the drone 1 remained stable in complex water currents, hovering 5-10 meters above the target.
[0067] 2. The storage block 6 is unlocked and the pushing device 10 is triggered.
[0068] Dual unlocking with electromagnetic lock and mechanical latch: After the control system sends the release command, the electromagnetic lock inside the swimming ring storage block 2 is de-energized, releasing the magnetic block outside the storage block 6. Simultaneously, the transverse drive motor 14 drives the L-shaped block 16 to squeeze the triangular block 12 on the outer side of the slider 11, disengaging it from the latch 13 slot and releasing the one-way mechanical lock.
[0069] The dual motors work together to push out the storage block 6: the longitudinal drive motor 15 is started to push the unlocked storage block 6 toward the cavity outlet along the slide slot, ensuring that the storage block 6 moves in a straight line during the pushing process.
[0070] 3. Squeeze and inflate the balloon ring 5.
[0071] During the pushing process, two sets of extrusion blocks 9 within the chamber simultaneously apply squeezing force to the first and second bladders 7, 8, respectively. This ruptures the membrane separating the sodium bicarbonate bladder 7 and the citric acid solution bladder 8, which are positioned in close proximity. The mixture of the two reacts with an acid-base reaction, rapidly generating carbon dioxide gas. This gas flows through the one-way valve at the inflation port of the storage block 6 and is then pumped into the bladder ring 5, causing it to expand into a ring-shaped buoyant structure within 4-8 seconds.
[0072] 4. Multiple sets of swimming rings are deployed and provided with buoyancy support.
[0073] Flexible deployment of single or multiple groups: The electromagnetic lock array supports independent control, allowing for single or continuous release of multiple groups based on the number of people in the water. Each group of storage blocks 6 is released, carrying the inflated bladder ring 5 with it into the water. The symmetrical connection between the ends of the bladder ring 5 and the storage blocks 6 ensures even inflation, forming a regular ring shape that is easy for people in the water to grasp.
[0074] The safety of the drone 1 is ensured. If the drone 1 accidentally falls into the water, the entire drone can be kept afloat, protecting the internal electronic equipment and the remaining swimming ring, thus buying time for secondary launch or return.
[0075] In summary, the water rescue device of the present embodiment can quickly locate a person in the water and deploy a swimming ring, buying time for rescue. It supports the continuous deployment of multiple groups of swimming rings, adapting to single or group rescue scenarios. The swimming ring can be quickly inflated to provide reliable buoyancy support.
