Description

Technical Field

[0001] The present invention relates to the technical field of marine rescue, and in particular to an inflatable airbag type unmanned marine rescue device and a rescue method. Background Art

[0002] In the current field of maritime rescue, the traditional method of rescuing people who fall into the water mainly relies on manned helicopters and ships as operating platforms, and uses rescue nets, hanging baskets, and projectile lifebuoys for rescue. However, these methods have obvious limitations in actual operation. The rescue process often requires the rescued to have a certain physical strength and clear consciousness in order to be able to grab or climb the rescue equipment. However, in emergency rescue situations, weak and overly frightened people who fall into the water may not be able to effectively cooperate with the rescue operation. Children, due to their incomplete physical development and limited cognitive ability, find it even more difficult to follow the instructions of the rescuers to rescue themselves. In this case, traditional rescue equipment and methods often seem to be incapable of doing so, which not only reduces the success rate of rescue, but may also delay the rescue time and increase the risk of life of the rescued.

[0003] In addition, the existing rescue equipment is relatively complex to operate, requiring professional training for rescuers, and the stability and reliability of these equipment will also be affected in harsh marine environments. Therefore, the field of marine rescue urgently needs a new type of rescue technology that can eliminate or reduce the active cooperation of the rescued persons, improve the automation and adaptability of the rescue, and ensure that all drowning people can be rescued quickly and effectively in a complex and changeable marine rescue environment. Summary of the invention

[0004] To this end, the technical problem to be solved by the present invention is to overcome the problem of limited usage scenarios of marine rescue equipment in the prior art, and to provide an inflatable airbag-type unmanned marine rescue device and rescue method.

The airbags can be horizontally unfolded toward the center of the assembly frame, and any of the airbags is provided with a connecting channel. The middle part of any of the lassoes is penetrated and connected to two adjacent connecting channels, and both ends of any of the lassoes are connected to the assembly frame. When the airbags are in the unfolded state, at least two of the airbags enclose a fastening space, and the lasso is gathered toward the fastening space through the airbags to fix the person to be rescued.

[0006] In one embodiment of the present invention, the enclosing assembly includes four airbags and four lassoes, and the four airbags are evenly spaced around the assembly frame.

[0007] In one embodiment of the present invention, the rescue mechanism includes two enclosing components, which are arranged in parallel and spaced apart, wherein when the airbag is in the deployed state, the fastening space enclosed by one enclosing component fixes the chest and abdomen of the person to be rescued, and the fastening space enclosed by the other enclosing component fixes the hips and legs of the person to be rescued.

[0008] In one embodiment of the present invention, the assembly frame includes a first enclosure, a second enclosure and at least one support column, wherein the first enclosure and the second enclosure are arranged in parallel and spaced apart, two ends of at least one support column are respectively connected to the first enclosure and the second enclosure, and the two enclosing components are respectively connected to the first enclosure and the second enclosure.

[0009] In one embodiment of the present invention, the airbag comprises an extension portion and an extrusion portion when in the deployed state, wherein the extension portion is connected to the assembly frame and extends horizontally toward the center of the assembly frame, and the extrusion portion abuts against the adjacent airbag and encloses the fastening space.

[0010] In one embodiment of the present invention, an inflation air pump and a pressure sensor are provided inside the airbag, and the inflation air pump is signal-connected to the pressure sensor.

[0012] The present invention also provides a rescue method, which adopts the above-mentioned inflatable airbag type unmanned marine rescue device to perform marine rescue, which includes: step S1, collecting the positioning beacon of the person who fell into the water, and after moving to the corresponding sea area, locking the position of the person to be rescued; step S2, making the rescue mechanism descend toward the person to be rescued until the person to be rescued is inside the rescue mechanism; step S3, inflating the airbag so that the person to be rescued is fixed in the fastening space; step S4, lifting the rescue mechanism, making the person to be rescued leave the water surface, and then transferring him to the rescue transfer platform.

[0013] In one embodiment of the present invention, in step S3, pressure detection is performed by a pressure sensor during the process of inflating the airbag, and when the detection value reaches a preset parameter, inflation is stopped and pressure is maintained. At this time, the surrounding assembly fixes the chest, abdomen, buttocks and legs of the rescuer, and the lasso is within the range of motion of the arm of the rescuer for the rescuer to grasp.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Embodiment 1

[0019] The present embodiment provides an inflatable airbag type unmanned marine rescue device, which includes: an aircraft 100; a rescue mechanism 200, which is moved by the aircraft 100, and includes: an assembly frame 210, which is connected to the aircraft 100; an enclosure component 220, which is connected to the assembly frame 210, and includes at least two airbags 221 and at least two lassoes 222. The airbags 221 can be horizontally unfolded toward the center of the assembly frame, and any of the airbags 221 is provided with a connecting channel 2211, and the middle part of any of the lassoes 222 is penetrated and connected to two adjacent connecting channels 2211, and both ends of any of the lassoes 222 are connected to the assembly frame. When the airbags 221 are in the unfolded state, at least two of the airbags 221 enclose a fastening space 223, and the lassoes 222 are gathered toward the fastening space 223 through the airbags 221 to fix the person to be rescued.

[0020] The inflatable airbag type unmanned marine rescue device described in this embodiment realizes the surrounding and fixing of the rescue personnel through the rescue mechanism 200 with different states, and can automatically achieve a stable connection with the rescue personnel, thereby achieving efficient rescue actions in scenarios without the need for personnel cooperation. Compared with conventional rescue devices, this application has significant advantages such as high degree of automation, wide application scenarios, firm and stable connection, strong controllability and high rescue efficiency, and has broad application prospects in this field.

[0021] See also Figure 1As shown, the aircraft 100 in this embodiment is used to provide flight movement power for the rescue mechanism 200, which includes a lifting assembly 120. The lifting assembly 120 is preferably a plurality of retractable connecting rods, the fixed ends of the plurality of connecting rods are connected to the cabin 110, and the retractable ends are connected to the rescue mechanism 200 to achieve the lifting and moving of the rescue mechanism 200. Furthermore, the rigid structure of the connecting rods can also improve the stability of the rescue mechanism 200 during the lifting process. In different embodiments, the lifting assembly 120 can also be set to other structures such as a pulling rope according to actual use requirements, and the present invention does not make specific restrictions on this.

[0022] Furthermore, the aircraft 100 in this embodiment also includes a control system, which includes a central control module, a positioning module, an airborne sensor, and a feedback module, wherein the positioning module, the airborne sensor, and the feedback module are respectively connected to the central control module by signals, wherein the pressure sensor in the airbag 221 is connected to the feedback module. In this embodiment, during the actual operation, the operator can perform real-time control and parameter preset of each module through the control system, thereby improving the flexibility of use, scope of application, and controllability of the device.

[0023] Figure 2The schematic diagram of the three-dimensional structure of the airbag 221 in the inflatable airbag type unmanned marine rescue device when it is in a contracted state is shown, wherein the assembly frame 210 is configured as a hollow circular frame structure in the horizontal direction, and the person to be rescued is set inside the assembly frame 210. The assembly frame 210 in this embodiment provides an installation and connection platform for the aircraft 100 and the surrounding assembly 220 on the one hand, and also forms an overall rigid structure of the rescue mechanism 200 on the other hand, which can be mutually squeezed with the surrounding assembly 220 during the operation process to form a stable clamping effect on the rescued person. Specifically, in order to disperse the force of squeezing the rescued person by a single surrounding assembly 220 and avoid squeezing damage to the rescued person, the rescue mechanism 200 in this embodiment includes two surrounding assemblies 220, which are arranged in parallel and spaced apart, wherein, when the airbag 221 is in the deployed state, the fastening space 223 enclosed by one surrounding assembly 220 fixes the chest and abdomen of the person to be rescued, and the fastening space 223 enclosed by the other surrounding assembly 220 fixes the hips and legs of the person to be rescued. Based on this, during the rescue process, the salvaging mechanism 200 can simultaneously clamp and support multiple parts of the rescue personnel, thereby minimizing the discomfort of the personnel. Specifically, the assembly frame 210 in this embodiment includes a first enclosure 211, a second enclosure 212 and at least one support column 213, wherein the first enclosure 211 and the second enclosure 212 are arranged in parallel and spaced apart, and the two ends of at least one support column 213 are respectively connected to the first enclosure 211 and the second enclosure 212, and the two enclosure components 220 are respectively connected to the first enclosure 211 and the second enclosure 212. It is worth noting that in different rescue scenarios, the first enclosure 211 and the second enclosure 212 can be set to different circle openings according to actual use requirements to improve their fixing effect.

[0024] See also Figure 2As shown, the enclosing assembly 220 in this embodiment includes four airbags 221 and four lassoes 222, and the four airbags 221 are evenly spaced around the assembly frame 210. Based on the above structure, when the airbag 221 is inflated, the enclosing assembly 220 can be synchronously extended from four directions to the center of the assembly frame 210, thereby not only reducing the formation time of the fixed space and improving the rescue efficiency, but also adjusting the posture of the rescuer from four directions at the same time. In addition, even if a certain airbag 221 fails during the rescue process, it will not cause the overall failure of the rescue mechanism 200. In different embodiments, the airbag 221 can be configured to other numbers, and the present invention does not make specific restrictions on this. In this embodiment, an air pump is provided inside the airbag 221. In order to avoid extrusion damage to the rescuer due to over-inflation, a pressure sensor is also provided inside the airbag 221 in this embodiment. The air pump is connected to the pressure sensor signal. When the pressure sensor detects that the relative extrusion force of the airbag 221 reaches a predetermined parameter, it stops inflating and can maintain pressure.

[0025] See also Figure 3 As shown, a connecting channel 2211 is provided in the middle of the airbag 221 in this embodiment. The connecting channel 2211 extends along the expansion direction of the airbag 221 and has a sealing effect to isolate the internal and external environments of the airbag 221. The connecting channels 2211 of two adjacent airbags 221 are penetrated in the middle of the lasso 222, and are arranged to fit the surface of the corresponding airbag 221, so that it can be retracted as the airbag 221 expands. On the one hand, it can guide the expansion direction of the airbag 221, and on the other hand, it can also be held by the person to be rescued, so that the person to be rescued can autonomously adjust the body balance during the lifting process.

[0026] See also Figure 4 and Figure 5 As shown, the airbag 221 in this embodiment includes an extension portion 2212 and an extrusion portion 2213 when in the expanded state, wherein the extension portion 2212 is connected to the assembly frame 210 and extends horizontally toward the center of the assembly frame, and the extrusion portion 2213 abuts against the adjacent airbag 221 and encloses the fastening space 223. Embodiment 2

[0027] See also Figure 6 As shown, this embodiment provides a salvaging method, which uses the inflatable airbag type unmanned marine salvaging device described in Example 1 to perform marine salvaging, and includes: Step S1: Collect the positioning beacons of the people who fall into the water, move to the corresponding sea area, and lock the position of the people to be rescued; Step S2, lowering the rescue mechanism 200 toward the person to be rescued until the person to be rescued is inside the rescue mechanism 200; Step S3, inflate the airbag 221 to fix the person to be rescued in the fastening space 223; further, according to the present invention, during the process of inflating the airbag 221, pressure detection is performed through a pressure sensor, and when the detection value reaches a preset parameter, inflation is stopped and pressure is maintained. At this time, the surrounding component 220 fixes the chest, abdomen, buttocks and legs of the person to be rescued, and the lasso 222 is located within the arm movement range of the person to be rescued so that the person to be rescued can grab and hold.

[0028] Step S4: lifting the rescue mechanism 200 to remove the rescued person from the water and then transferring him to the rescue transfer platform.

[0029] In summary, the inflatable airbag type unmanned marine rescue device and rescue method described in the present invention realizes the surrounding and fixation of the rescue personnel through the rescue mechanism 200 with different states, which can automatically achieve a stable connection with the rescue personnel, thereby achieving efficient rescue actions in scenarios without the need for personnel cooperation. Compared with conventional rescue devices, this application has significant advantages such as high degree of automation, wide application scenarios, firm and stable connection, strong controllability, and high rescue efficiency, and has broad application prospects in this field.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
