Description

Technical Field

[0001] This invention relates to the field of marine fire rescue technology, and in particular to a surface rescue device for fire rescue. Background Technology

[0002] Unmanned surface rescue equipment, as a maritime rescue tool, can overcome wind and waves to sail to the rescue site, carry out rescue operations on the sea, and transfer people who have fallen into the water to a safe location.

[0003] In relevant technologies, a mechanically driven arm is typically used to pull a person out of the water using a net, and then place them directly on the ship's deck or in a containment compartment. However, in actual maritime rescue operations, secondary injuries to those in the water are often caused by improper positioning. Because current technologies cannot convert and maintain the person in the water in a safe position such as lying on their side, they are often placed in unsafe positions (e.g., supine, prone). If the person is prone, it can compress the chest cavity, easily leading to breathing difficulties; if the person is supine, vomit or water can enter the airway on a rough sea surface, easily leading to suffocation. Such unsafe positions greatly increase the risk of secondary injuries to the person in the water under actual maritime rescue conditions, making it difficult to guarantee their safety. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, the purpose of this invention is to provide a water surface rescue device for fire rescue, which can convert and maintain a person who has fallen into the water in a safe side-lying position, so as to avoid secondary injury caused by improper body position.

[0006] To achieve the above objectives, this invention proposes a surface rescue device for firefighting and rescue, comprising: an unmanned catamaran connected to a net clamp via a drive assembly; a containment compartment disposed on the unmanned catamaran; and two attitude adjustment assemblies symmetrically disposed within the containment compartment, each attitude adjustment assembly comprising: a lifting platform, multiple first electric push plates, and multiple second electric push plates. The lifting platform is disposed on the lower inner wall of the containment compartment, the multiple first electric push plates are respectively disposed on one side of the lifting platform, and the multiple second electric push plates are disposed on the inner wall of the containment compartment near the other side of the lifting platform. The drive assembly is configured to drive the net. The net, held by the clamp, retrieves the person who has fallen into the water. After the net is transferred to the top of the lifting platform, the clamp releases the net so that the person falls onto the lifting platform. An image acquisition module, installed on the unmanned catamaran, is used to detect the attitude and position information of the person who has fallen into the water in the containment compartment in real time. A controller is electrically connected to the image acquisition module and the attitude adjustment components respectively. The controller is configured to control the lifting platform of one attitude adjustment component to rise when the acquired attitude information is lying down, and to control the first electric push plate on one attitude adjustment component and the second electric push plate on the other attitude adjustment component to extend and push the person who has fallen into the water to a side-lying position.

[0007] In one embodiment of the present invention, a conveyor belt module is provided on the upper part of the lifting platform, and the conveyor belt module is used to adjust the placement position of the person who has fallen into the water on the lifting platform.

[0008] In one embodiment of the present invention, the drive assembly includes: a lead screw drive module, a drive chamber, and a rotating device, wherein the lead screw drive module is disposed on the unmanned catamaran, the drive chamber is disposed on the lead screw drive module, the lead screw drive module is used to drive the drive chamber to move horizontally or vertically, the rotating device is disposed on the drive chamber, and the net clamp is disposed on the rotating device.

[0009] In one embodiment of the present invention, the rotating device includes a toothed belt drive mechanism and a rotating shaft. The toothed belt drive mechanism is disposed in the drive chamber, and the rotating shaft is rotatably disposed on the drive chamber and connected to the net-catching clamp.

[0010] In one embodiment of the present invention, the net clamp includes a frame and a lifting plate. The frame is disposed on the rotating device, and an installation groove is provided on the inner wall of the frame. The lifting plate is disposed in the installation groove, and the edge of the net is placed in the installation groove. The lifting plate abuts against the net. The lifting plate is configured to press the net to fix it on the frame, or to retract to release the net.

[0011] In one embodiment of the present invention, the mounting groove is a square frame-shaped groove, and the lifting plate includes: a plurality of first electric push rods and a pressure plate. The plurality of first electric push rods are respectively disposed in the mounting groove. The pressure plate is a square frame-shaped plate. The pressure plate is connected to the driving end of the first electric push rods and abuts against the mesh.

[0012] In one embodiment of the present invention, the lifting platform includes: a plurality of hydraulic lifts and a load-bearing platform, wherein the plurality of hydraulic lifts are respectively disposed on the lower inner wall of the receiving chamber, and the load-bearing platform is connected to the drive end of the hydraulic lifts.

[0013] In one embodiment of the present invention, it further includes: a plurality of auxiliary support devices, the auxiliary support devices including: a winch and a connecting rope, the winch being disposed on the drive chamber, one end of the connecting rope being connected to the winch, and the other end of the connecting rope being connected to the frame.

[0014] In one embodiment of the present invention, the first electric push plate includes: a first electric telescopic rod, a first abutment plate, and a first pressure sensor. A first groove is formed on the side wall of the lifting platform, the first electric push plate is disposed in the first groove, the first pressure sensor is disposed on the drive end of the first electric push plate, and the first abutment plate is disposed on the first pressure sensor. The second electric push plate includes: a second electric telescopic rod, a second abutment plate, and a second pressure sensor. A second groove is formed on the inner side wall of the containment chamber, the second electric push plate is disposed in the second groove, the second pressure sensor is disposed on the drive end of the second electric push plate, and the second abutment plate is disposed on the second pressure sensor.

[0015] In one embodiment of the present invention, it further includes: two protective components symmetrically arranged within the containment chamber, wherein the inner wall of the containment chamber is provided with a mounting groove, the mounting groove being disposed above the second electric push plate, and the protective components include: a second electric push rod, a third electric push rod, a mounting plate, and an airbag, wherein the second electric push rod is disposed within the mounting groove, the third electric push rod is disposed on the drive end of the second electric push rod, the mounting plate is disposed on the drive end of the third electric push rod, and the airbag is disposed below the mounting plate;

[0016] The second electric push rod is used to drive the third electric push rod to move vertically, and the third electric push rod is used to drive the mounting plate to move horizontally.

[0017] The beneficial effects of this invention are:

[0018] By employing two symmetrically arranged posture adjustment components, a single-sided lifting platform is raised to disrupt the force balance of a person lying flat or prone in the water. Multiple first and second electric push plates extend in opposite directions to apply thrust, which can rotate a person in an unsafe position (such as supine or prone) and maintain them in a safe side-lying position. This effectively reduces the risk of chest compression caused by a prone position and the secondary injury risks such as vomit and water backflow into the airway due to the turbulent sea surface when the person is supine, thus improving the safety of the sea-based transfer of a person who has fallen into the water.

[0019] The first electric push rod controls the fixing and release of the frame and net by driving the pressure plate to engage or disengage with the net. After the salvage is completed, the pressure plate above the rescue chamber is released from the net, allowing the net and the person in the water to fall onto the lifting platform together. This avoids the obstruction caused by the person's clothing or personal belongings getting stuck on the fixed net, eliminates the risk of injury from hard pulling, and significantly improves rescue efficiency.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following describes an embodiment of the fire and rescue water surface rescue equipment of the present invention with reference to the accompanying drawings.

[0034] Firefighting and rescue water surface rescue equipment according to embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it may include: an unmanned catamaran 1, a containment cabin 5, an attitude adjustment assembly 6, an image acquisition module 7, and a controller.

[0035] The unmanned catamaran 1 is connected to the net-catching clamp 3 via the drive assembly 2. The containment compartment 5 is set on the unmanned catamaran 1. The drive assembly 2 is configured to drive the net body 4 held by the net-catching clamp 3 to retrieve the person who has fallen into the water. After the net body 4 is transferred to the top of the lifting platform 61, the net-catching clamp 3 releases the net body 4 so that the person who has fallen into the water can fall onto the lifting platform 61.

[0036] It is understood that the net clamp 3 described in this embodiment can clamp or release the net body 4 as needed. After retrieving the person from the water, when the person begins to be placed in the water, it can prevent the person's clothes and personal belongings from getting stuck on the net body 4, which would easily cause difficulty in untying them, so that the person can fall into the water quickly and stably onto the lifting platform 61.

[0037] Two attitude adjustment components 6 are symmetrically arranged inside the containment chamber 5. Each attitude adjustment component 6 includes a lifting platform 61, a plurality of first electric push plates 62 and a plurality of second electric push plates 63. The lifting platform 61 is arranged on the lower inner wall of the containment chamber 5. The plurality of first electric push plates 62 are respectively arranged on one side of the lifting platform 61, and the plurality of second electric push plates 63 are arranged on the inner wall of the containment chamber 5 on the other side near the lifting platform 61.

[0038] It should be noted that the two attitude adjustment components 6 described in this embodiment are symmetrically arranged inside the containment chamber 5, so the two lifting platforms 61 are also arranged side by side at the bottom of the containment chamber 5. One side of the lifting platform 61 refers to the adjacent side where the two lifting platforms 61 are close to each other, while the other side of the lifting platform 61 refers to the outer side facing away from the adjacent side.

[0039] An image acquisition module 7 is installed on the unmanned catamaran 1, and is positioned above the lifting platform 61. The image acquisition module 7 is used to detect the attitude and position information of the person who has fallen into the water in the containment chamber 5 in real time. A conveyor belt module 8 is installed on the upper part of the lifting platform 61, and the conveyor belt module 8 is used to adjust the placement position of the person who has fallen into the water on the lifting platform 61.

[0040] It should be noted that the image acquisition module 7 described in this embodiment includes a motorized pan-tilt unit and a camera assembly mounted on the motorized pan-tilt unit (the camera assembly can be a vision sensor, industrial camera, or infrared camera, etc.). The motorized pan-tilt unit is configured to drive the camera assembly to perform horizontal rotation and pitch angle adjustment, thereby achieving dynamic image acquisition of the containment chamber without blind spots.

[0041] The controller is mounted on the containment chamber 5 and is electrically connected to the conveyor belt module 8, the image acquisition module 7, and the attitude adjustment component 6. The controller is configured to control the conveyor belt module 8 to adjust the position of the person who has fallen into the water on the lifting platform 61, so that the person lies flat at the junction of the two lifting platforms 61 (i.e., spanning the two lifting platforms 61). When the acquired attitude information is lying down (prone or supine), the controller raises the lifting platform 61 of one attitude adjustment component 6 and controls the first electric push plate 62 on one attitude adjustment component 6 and the second electric push plate 63 on the other attitude adjustment component 6 to extend and push the person into a side-lying position.

[0042] It should be noted that the controller is equipped with a wireless communication module, which can be connected to an external remote control console (e.g., communication connection) via the wireless communication module. When adjusting the attitude, the staff can manually adjust the attitude of the person in the water based on the attitude and position information of the person in the water in the containment chamber 5 transmitted by the image acquisition module 7. Alternatively, the controller can automatically adjust the attitude according to a preset program. The authority for manual adjustment is greater than that for automatic adjustment, and manual adjustment can intervene in automatic adjustment at any time.

[0043] The controller can also be electrically connected to the unmanned catamaran 1, the drive assembly 2, and the net clamp 3 respectively. The remote control console can control the unmanned catamaran 1, the drive assembly 2, and the net clamp 3 respectively through the controller.

[0044] To clearly illustrate the previous embodiment, in one embodiment of the present invention, as follows: Figure 1 and Figure 2 As shown, the drive assembly 2 may include: a screw drive module 21, a drive chamber 22, and a rotating device 23. The screw drive module 21 is mounted on the unmanned catamaran 1, the drive chamber 22 is mounted on the screw drive module 21, the screw drive module 21 is used to drive the drive chamber 22 to move horizontally or vertically, the rotating device 23 is mounted on the drive chamber 22, and the net clamp 3 is mounted on the rotating device 23.

[0045] It should be noted that the lead screw drive module 21 described in this embodiment may include: a horizontal lead screw drive module and a vertical lead screw drive module. The horizontal lead screw drive module is disposed on the unmanned catamaran 1, the vertical lead screw drive module is disposed on the drive end of the horizontal lead screw drive module, and the drive chamber 22 is disposed on the vertical lead screw drive module. The horizontal lead screw drive module is used to drive the vertical lead screw drive module to move horizontally, and the vertical lead screw drive module is used to drive the drive chamber 22 to move vertically.

[0046] Both the horizontal and vertical drive modules of the ball screw adopt ball screw drivers. The ball screw driver may include: a housing, a drive motor, a ball screw, a ball slider, and a connecting part. The drive motor is located in the housing, the ball screw is located at the drive end of the drive motor, the ball slider is located on the ball screw, and the ball slider is connected to the driven part through the connecting part. The drive motor drives the ball screw to rotate, and the ball slider can move on the rotating ball screw.

[0047] As one possible scenario, such as Figure 6 As shown, the rotating device 23 may include: a toothed belt drive mechanism 231 and a rotating shaft 232. The toothed belt drive mechanism 231 is disposed in the drive chamber 22, and the rotating shaft 232 is rotatably disposed on the drive chamber 22 through a bearing. The rotating shaft 232 is connected to the net clamp 3.

[0048] It is understood that the toothed belt drive mechanism 231 described in this embodiment may include: a first motor set, a driving wheel, a driven wheel, and a toothed belt. The first motor set is disposed in the drive compartment 22, the driving wheel is disposed on the drive end of the first motor set, the driven wheel is disposed on the rotating shaft 232, the driving wheel and the driven wheel are connected by a toothed belt, and the toothed belt meshes with the driving wheel and the driven wheel respectively.

[0049] As another possible scenario, the rotating device 23 may be a second motor unit, and the net-catching clamp 3 may be located at the drive end of the second motor unit.

[0050] In one embodiment of the present invention, such as Figure 6 , Figure 7 and Figure 8 As shown, the net clamp 3 may include a frame 31 and a lifting plate 32. The frame 31 is mounted on the rotating device 23 (rotating shaft 232 or the driving end of the second motor unit) of the driving assembly 2, and the inner wall of the frame 31 is provided with a mounting groove 9. The lifting plate 32 is disposed in the mounting groove 9, and the edge of the net 4 is placed in the mounting groove 9. The lifting plate 32 abuts against the net 4. The lifting plate 32 is configured to press the net 4 to fix the net 4 on the frame 31, or to retract to release the fixation of the net 4. The mounting groove 9 is a square-shaped groove. The lifting plate 32 includes a plurality of first electric push rods 321 and a pressure plate 322. The plurality of first electric push rods 321 are respectively disposed in the mounting groove 9. The pressure plate 322 is a square-shaped plate. The pressure plate 322 is connected to the driving end of the first electric push rods 321 and abuts against the net 4.

[0051] In one embodiment of the present invention, such as Figure 3 As shown, the lifting platform 61 includes: multiple hydraulic lifts 611 and a load-bearing platform 612. The multiple hydraulic lifts 611 are respectively installed on the lower inner wall of the receiving chamber 5, and the load-bearing platform 612 is connected to the drive end of the hydraulic lifts 611.

[0052] It is understood that the hydraulic lift 611 described in this embodiment can drive the support platform 612 to move vertically.

[0053] Specifically, in the event of a maritime emergency, it can be used in conjunction with external aerial reconnaissance equipment (such as drones). The drone will first fly to the target waters to conduct a wide-area aerial search. Once the person in the water is located, the unmanned catamaran 1 can be driven to the waters where the person is located.

[0054] After the unmanned catamaran 1 approaches the person who has fallen into the water, the screw drive module 21 drives the drive chamber 22 to move vertically and horizontally, moving the drive chamber 22 to the salvage position (at which the net body 4 can be rotated to retrieve the person who has fallen into the water). Then, the toothed belt drive mechanism 231 drives the net clamp 3 with the net body 4 to rotate (for example, rotate 90°) through the rotating shaft 232, and retrieves the person who has fallen into the water.

[0055] After the retrieval is completed, the drive assembly 2 transfers the net clamp 3 and the person in the water to the lifting platform 61 above the containment chamber 5. Multiple first electric push rods 321 retract the pressure plate 322, releasing the clamping and fixing of the net body 4's edges, causing the net body 4 to separate from the frame 31. The person in the water, along with the net body 4, falls directly and smoothly onto the two lifting platforms 61 inside the containment chamber 5 under the influence of gravity. This direct release of the net body 4 avoids the difficulty of untangling the person's clothing or belongings that might get stuck on the fixed net body 4, preventing secondary pulling on the person and improving rescue efficiency.

[0056] After the person falls into the containment chamber 5, the image acquisition module 7 collects the person's posture and position information inside the chamber in real time. Based on this position information, the two conveyor belt modules 8 drive the person's body to move so that its body is located at the junction of the two symmetrical lifting platforms 61.

[0057] Based on the posture information, it can be determined whether the person who fell into the water is in an unsafe posture such as supine or prone. If in an unsafe posture, and one of the lifting platforms 61 of the posture adjustment component 6 is raised, since the person is straddling two lifting platforms 61, the raising of one side of the lifting platform 61 breaks the force balance of the supine position, causing the person to slide and deflect towards the unraised lifting platform 61. Multiple first electric push plates 62 corresponding to the raised lifting platform 61 (the first electric push plates 62 are installed on one side of the lifting platform 61 within the posture adjustment component 6 where the raised lifting platform 61 is located) and multiple second electric push plates 63 corresponding to the unraised lifting platform 61 (the second electric push plates 63 are installed on the inner wall of the containment chamber 5 within the posture adjustment component 6 where the unraised lifting platform 61 is located) extend towards each other and cooperate. The first electric push plate 62 and the second electric push plate 63 apply opposing pushing forces from both sides of the person who has fallen into the water, turning the person into a side-lying position and continuously abutting against each other to maintain this safe position.

[0058] Throughout the rescue and attitude adjustment process, staff can access the image acquisition module 7 and the drone's transmitted feeds at any time via a remote control console. In extremely complex sea conditions or when the person in the water faces special circumstances, staff can perform manual operations to maximize the safety of the person in the water.

[0059] In one embodiment of the present invention, such as Figure 1 and Figure 6As shown, it may also include: multiple auxiliary support devices 10, each auxiliary support device 10 including: a winch 101 and a connecting rope 102, the winch 101 being mounted on the drive chamber 22, one end of the connecting rope 102 being connected to the winch 101, and the other end of the connecting rope 102 being connected to the frame 31.

[0060] It should be noted that, in this embodiment, the winch 101 provides auxiliary support to the net clamp 3 by winding and unwinding the connecting rope 102 (e.g., wire rope). When the rotating device 23 drives the net body 4 to rotate through the net clamp 3 to retrieve the person who has fallen into the water, multiple winches 101 simultaneously adjust the connecting rope 102 to provide auxiliary support to the frame 31 on the net clamp 3.

[0061] In one embodiment of the present invention, such as Figure 3 , Figure 5 and Figure 9 As shown, the first electric push plate 62 may include: a first electric telescopic rod 621, a first abutment plate 622 and a first pressure sensor 623. The side wall of the lifting platform 61 is provided with a first groove, the first electric push plate 62 is disposed in the first groove, the first pressure sensor 623 is disposed on the driving end of the first electric push plate 62, and the first abutment plate 622 is disposed on the first pressure sensor 623.

[0062] The second electric push plate 63 may include: a second electric telescopic rod 631, a second abutment plate 632, and a second pressure sensor 633. A second groove is formed on the inner side wall of the containment chamber 5, the second electric push plate 63 is disposed in the second groove, the second pressure sensor 633 is disposed on the drive end of the second electric push plate 63, and the second abutment plate 632 is disposed on the second pressure sensor 633. It should be noted that the first abutment plate 622 and the second abutment plate 632 may be elastic flexible plates.

[0063] It is understood that the telescopic end of the electric actuator (e.g., the first electric actuator 321 or the second electric actuator 111) described in this embodiment is fixed to the pressure sensor (e.g., the first pressure sensor 623 or the second pressure sensor 633) by bolts. The back of the abutment (e.g., the first abutment 622 or the second abutment 632) is fixed to the force-bearing side of the pressure sensor (e.g., the first pressure sensor 623 or the second pressure sensor 633) by bolts.

[0064] During the contact process of the impact plate (e.g., the first impact plate 622 or the second impact plate 632), the first pressure sensor 623 or the second pressure sensor 633 monitors the thrust in real time to prevent the impact plate (e.g., the first impact plate 622 or the second impact plate 632) from causing crushing injury to the person falling into the water.

[0065] In one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 5 As shown, it may further include: two protective components 11 symmetrically arranged within the containment chamber 5; the auxiliary support device 10 and the protective components 11 are electrically connected to the controller; the inner wall of the containment chamber 5 has a mounting groove, which is located above the second electric push plate 63; the protective component 11 includes: a second electric push rod 111, a third electric push rod 112, a mounting plate 113, and an airbag 114; wherein the second electric push rod 111 is located within the mounting groove, the third electric push rod 112 is located on the drive end of the second electric push rod 111, the mounting plate 113 is located on the drive end of the third electric push rod 112, and the airbag 114 is located at the lower part of the mounting plate 113. The second electric push rod 111 is used to drive the third electric push rod 112 to move vertically, and the third electric push rod 112 is used to drive the mounting plate 113 to move horizontally.

[0066] It should be noted that the inflation port of the airbag 114 is connected to a miniature air pump (or high-pressure air cylinder) installed on the unmanned catamaran 1 via an air supply pipeline, and an electrically controlled valve is installed on the air supply pipeline.

[0067] Specifically, in rough sea conditions, the violent rolling and pitching of the hull may cause a person who has fallen into the water inside containment compartment 5 to bounce vertically, potentially causing secondary impact injuries. After the person is transferred into containment compartment 5, the third electric actuator 112 drives the mounting plate 113 to extend horizontally towards the center of the compartment, while the second electric actuator 111 drives the mounting plate 113 to move vertically downward via the third electric actuator 112, moving the airbag 114 and suspending it above the person's body. When the hull experiences violent rolling due to waves, the airbag 114, with its internal air pressure buffering and flexible deformation characteristics, absorbs the kinetic energy of the person's vertical bounce.

[0068] It should be noted that there are two symmetrically arranged lead screw drive modules 21 and rotating devices 23 (the two lead screw drive modules 21 are respectively arranged on the two hulls of the unmanned catamaran 1), and multiple third electric push rods 112 are provided in one of the protection components 11, and multiple second electric push rods 111 are connected to each third electric push rod 112.

[0069] The motors described in the above embodiments (e.g., the first motor group, the second motor group, the drive motor, etc.) are equipped with brakes, which can make the motor stop running quickly. A gearbox is provided on the drive end of the motor. The output shaft of the motor body is connected to the input end of the gearbox. The output end of the gearbox constitutes the power output end of the motor group. The speed of the motor output is adjusted by the gearbox.

[0070] In summary, the water rescue equipment for fire rescue according to the embodiments of the present invention can convert and maintain the person who has fallen into the water in a safe side-lying position, avoiding secondary injury caused by improper body position.
