Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicle rescue, in particular to a wounded transport pod based on an unmanned aerial vehicle. Background Art

[0002] In emergency situations such as battlefields and natural disasters, after the wounded are injured, due to insufficient medical conditions, they cannot be treated locally and need to be transferred. Traditional ground transfer methods may be restricted by terrain, traffic and other factors. When encountering some bumpy and muddy roads that are inconvenient to walk on, the transportation efficiency is low, resulting in the inability to treat the wounded in time, and thus missing the best time for treatment. Therefore, in the process of transporting the wounded, special drone wounded transfer pods are often required to achieve fast and efficient wounded transfer.

[0003] For example, a Chinese patent application with publication number CN119037715A discloses a pod for transferring wounded persons based on a drone, which includes a main cabin body with an opening at one end and a cabin door hinged on the open end of the main cabin body, the cabin door is controlled by an opening and closing assembly, and moving wheels are arranged on the main cabin body to facilitate rapid movement of the main cabin body, which is beneficial to the rapid transfer of the wounded, and the moving wheels are connected to the main cabin body through a first buffer assembly, so that the drone can play a buffering role when landing, preventing the wounded from shaking and causing secondary injuries, and a second buffer assembly is arranged under the stretcher board to further play a buffering role.

[0004] Although this existing technology has achieved the goal of improving the stability of the drone during landing, when the drone pod is transporting the wounded, especially when performing a dive or a rise operation, the drone pod will change its angle along with the drone, causing the wounded to be in a tilted state, which may further aggravate the wounded's injuries and affect subsequent treatment.

[0017] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting a balancing mechanism, the spherical rod can rotate along with the connecting plate, so that the patient transfer pod can rotate, so that when the UAV changes its flight attitude to fly obliquely upward, the patient transfer pod can change the angle between it and the UAV, so as to always remain in a horizontal state. In this way, when the UAV changes its flight attitude, the patient transfer pod can be automatically adjusted, thereby reducing the discomfort or injury that may be caused by changes in flight attitude, thereby ensuring the safety and comfort of the wounded, thereby improving the overall practicality of the device.

[0019] By setting the coordination of parts such as the ring gear, when the UAV is initially flying sideways and the flight attitude of the UAV changes from sideways flight to oblique flight to the side and upward, the output end of the first drive motor drives the spur gear to rotate, thereby driving the ring gear to rotate, thereby driving the connecting ring to rotate, and when the rotating block rotates to the forward direction of the UAV, the rotating block stops rotating. At this time, the PLC controller controls the hydraulic cylinder to start and drive the first rotating rod to move downward, thereby pushing the wounded transport pod to rotate in different directions, so that when the UAV flies obliquely in different directions, the wounded transport pod can rotate in different directions, so that the wounded transport pod can automatically adjust the angle and direction of the transport pod according to the change of the flight attitude of the UAV, thereby improving the adaptability and flexibility of the device, thereby improving the comfort of the wounded when transporting the wounded, reducing the harm to the wounded, and thus improving the overall practicality of the device.

[0020] By setting up an airflow output device, when the hydraulic cylinder drives the rotating block to move downward, so that the wounded transport pod can rotate adaptively, the PLC controller controls the air pump to start, and the output end of the air pump supplies air to the inner side of the first partition plate, thereby entering the inner side of the second connecting pipe through the first through groove and the second through groove, so that the gas can enter the inner side of multiple high-pressure nozzles and spray gas to the outside through multiple high-pressure nozzles, thereby offsetting the turbulence in the flight of the drone and reducing the flight resistance of the wounded transport pod, thereby improving the flight stability of the wounded transport pod, thereby improving the overall practicality of the device.

[0021] By setting and cooperating with the first partition plate and other parts, the second partition plate and the first partition plate divide the inner side of the sealing ring into four areas, and the four areas are respectively connected to the second connecting pipes in four directions. When the UAV flies forward, the first through groove is connected to the front area. When the air pump supplies gas, the gas can be directly supplied from the front area to the second connecting pipe, so that the gas can be sprayed in the flight direction by the high-pressure nozzle. At the same time, when the UAV changes the flight direction, the PLC controller controls the first drive motor to start. The output end of the first drive motor drives the rotating plate to rotate, and at the same time, it can drive the connecting strip to rotate, thereby driving the sealing ring to rotate, thereby driving the first partition plate to rotate, so that the first through groove can be moved to different positions and communicate with different areas, so as to supply gas to different areas, and when the UAV flies sideways, the first through groove changes position synchronously with the rotating block, so that the UAV always keeps supplying gas to the high-pressure nozzle in the flight direction, so that the high-pressure nozzle can always spray gas in the flight direction, thereby improving the flexibility and adaptability of the device, thereby improving the stability of the flight of the wounded transport pod, thereby improving the overall practicality of the device.

[0022] By setting the coordination of parts such as the fourth connecting pipe, when the UAV performs a dive or a supine operation, the PLC controller controls the hydraulic cylinder to start, drives the hydraulic cylinder to rotate, and drives the fourth connecting pipe to rotate. Under the action of the fixed rod, the high-pressure nozzle can always remain parallel to the UAV, so that when the UAV changes its angle, the high-pressure nozzle can change its angle at the same time, so that the gas ejected by the high-pressure nozzle is always kept consistent with the flight direction, so that the high-pressure nozzle can adapt to different flight angles and directions for gas injection, thereby further improving the stability of the flight of the wounded transport pod, thereby improving the overall practicality of the device.

[0043] An angle sensor for detecting the flight angle of the drone 1 can be installed inside the drone 1. The hydraulic cylinder 13 is controlled by the PLC controller, and the hydraulic cylinder 13 can be controlled to start intermittently. When the drone 1 changes its flight attitude from flying straight ahead to flying obliquely forward and upward, the angle sensor senses the tilt angle of the drone 1, and then the hydraulic cylinder 13 is controlled to start by the PLC controller. The output end of the hydraulic cylinder 13 controls the driving rotating block 11 to move downward, thereby driving the first rotating rod 7 to move downward, thereby driving the second connecting seat 41 to rotate under the action of the first rotating rod 7, thereby driving the limit block 10 to rotate, so that the spherical rod 6 can rotate with the connecting plate 9, so that the wounded transport pod 4 can rotate, so that when the drone 1 changes its flight attitude to fly obliquely upward, the wounded transport pod 4 can change the angle with the drone 1, so as to always remain in a horizontal state, thereby realizing that when the drone 1 changes its flight attitude, the wounded transport pod 4 can be automatically adjusted, thereby reducing the discomfort or injury that may be caused by the change in flight attitude, thereby ensuring the safety and comfort of the wounded, thereby improving the overall practicality of the device.

[0044] like Figures 2 to 5As shown, the rotating assembly includes a fixing ring 14 fixedly connected to the outer wall of the connecting column 5, a first driving motor 16 is installed on the top of the fixing ring 14, and a spur gear 17 is fixedly connected to the output end of the first driving motor 16, a connecting ring 15 is fixedly connected to the bottom of the rotating plate 12, and a ring gear 18 is fixedly connected to the inner side of the connecting ring 15, and the ring gear 18 is meshed with the spur gear 17, and four synchronous stretching assemblies are arranged at the bottom of the fixed plate 3; the synchronous stretching assembly includes four groups of first connecting seats 19 fixedly connected to the bottom of the fixed plate 3, each group of first connecting seats 19 is provided with two, and a second rotating rod 21 is rotatably connected between the two first connecting seats 19, and a connecting steel rope 22 is wound on the outer wall of the second rotating rod 21, and one end of the connecting steel rope 22 is fixedly connected to the wounded transport pod 4, a second driving motor 20 is installed on one side of the first connecting seat 19, and the output end of the second driving motor 20 passes through one side of the first connecting seat 19 and is fixedly connected to the second rotating rod 21.

[0045] The first drive motor 16 is controlled by a PLC controller, and the first drive motor 16 can be controlled to start intermittently. When the UAV 1 is initially flying sideways, and the flight attitude of the UAV 1 changes from sideways flight to oblique flight to the side and upward, the output end of the first drive motor 16 drives the spur gear 17 to rotate, thereby driving the ring gear 18 to rotate, thereby driving the connecting ring 15 to rotate, and when the rotating block 11 rotates to the forward direction of the UAV 1, the rotating block 11 stops rotating. At this time, the PLC controller controls the hydraulic cylinder 13 to start and drive the first rotating rod 7 to move downward, thereby pushing the wounded transport pod 4 to rotate in different directions, so that when the UAV 1 flies obliquely in different directions, the wounded transport pod 4 can rotate in different directions, so that the wounded transport pod 4 can automatically adjust the angle and direction of the transport pod according to the change of the flight attitude of the UAV 1, thereby improving the adaptability and flexibility of the device, thereby improving the comfort of the wounded during transportation, reducing the harm to the wounded, and improving the overall practicality of the device.

[0046] The second drive motor 20 is controlled by a PLC controller, which can control the intermittent start of the second drive motor 20. When the hydraulic cylinder 13 drives the wounded transport pod 4 to rotate, the PLC controller controls the second drive motor 20 to start, and the output end of the second drive motor 20 drives the second rotating rod 21 to rotate, thereby winding the connecting steel rope 22, thereby synchronously stretching the wounded transport pod 4 while the wounded transport pod 4 rotates, thereby further enhancing the stability of the wounded transport pod 4, so that the wounded transport pod 4 can always remain stable when the drone 1 is diving or rising, thereby improving the riding comfort of the wounded, thereby improving the overall stability of the device.

[0047] The four second drive motors 20 are individually controlled by a PLC controller to reel in or release.

[0048] like Figures 6 to 10 As shown, the airflow output device is arranged on the outer wall of the wounded transport pod 4, and is used for ejecting airflow outward from the outer wall of the wounded transport pod 4; the airflow output device includes a connecting shell 24 fixedly connected to the outer wall of the connecting column 5, and the outer wall of the connecting shell 24 is provided with four second through grooves 30 communicating with the interior, and a second connecting pipe 31 is installed on the inner side of each second through groove 30, and a first corrugated pipe 33 is installed at the bottom of the second connecting pipe 31, and a third connecting pipe 38 is installed at the bottom of the first corrugated pipe 33, and two fourth connecting pipes 39 are installed on one side of the third connecting pipe 38, and a high-pressure nozzle 35 is arranged on one side of the fourth connecting pipe 39, and a synchronous rotation component is arranged on the top of the high-pressure nozzle 35.

[0049] The synchronous rotation assembly includes a second bellows 34 installed on one side of the fourth connecting pipe 39, the other side of the second bellows 34 is fixedly connected to the high-pressure nozzle 35, a fixing rod 36 is fixedly connected to the bottom of the fixing plate 3, and the fixing rod 36 is fixedly connected to a high-pressure nozzle 35, one side of a high-pressure nozzle 35 is fixedly connected to a connecting rod 37, and one side of the connecting rod 37 is fixedly connected to another high-pressure nozzle 35.

[0050] The airflow output device also includes a sealing ring 25 rotatably connected to the inner side of the connecting shell 24, the top of the sealing ring 25 is fixedly connected to the first partition plate 26, four second partition plates 32 are fixedly connected to the inner side of the connecting shell 24, and the second partition plates 32 are attached to the outer wall of the first partition plate 26, a sealing ring for sealing is provided at the contact portion between the second partition plate 32 and the first partition plate 26, a first through groove 27 is provided on the inner side of the first partition plate 26, and a power assembly is provided at the bottom of the sealing ring 25.

[0051] The power assembly includes an air pump 28 installed on the top of the rotating plate 12, and a first connecting pipe 29 is installed at the output end of the air pump 28. The other end of the first connecting pipe 29 is installed at the air inlet of the sealing ring 25. The top of the rotating plate 12 is fixedly connected to the connecting strip 23, and the connecting strip 23 is fixedly connected to the sealing ring 25.

[0052] The air pump 28 is controlled by a PLC controller, which can control the intermittent start of the air pump 28. The air supply hole at one end of the air pump 28 is connected to the air supply device inside the wounded transport pod 4, so that air can be supplied to the inside of the air pump 28. When the hydraulic cylinder 13 drives the rotating block 11 to move downward, so that the wounded transport pod 4 can be adaptively rotated, the PLC controller controls the air pump 28 to start, and the output end of the air pump 28 supplies air to the inside of the first partition plate 26, thereby entering the inside of the second connecting pipe 31 through the first through groove 27 and the second through groove 30, so that the gas can enter the inside of the multiple high-pressure nozzles 35, and spray gas to the outside through the multiple high-pressure nozzles 35, so as to offset the turbulence in the flight of the drone 1 and reduce the flight resistance of the wounded transport pod 4, thereby improving the flight stability of the wounded transport pod 4, thereby improving the overall practicality of the device.

[0053] The second partition plate 32 and the first partition plate 26 divide the inner side of the sealing ring 25 into four areas, and the four areas are respectively connected to the second connecting pipes 31 in four directions. When the drone 1 flies forward, the first through groove 27 is connected to the front area, and the air pump 28 can directly supply the gas from the front area to the second connecting pipe 31 when supplying gas, so that the gas can be sprayed in the flight direction by the high-pressure nozzle 35. At the same time, when the drone 1 changes the flight direction, the PLC controller controls the first drive motor 16 to start, and the output end of the first drive motor 16 drives the rotating plate 12 to rotate, and can drive the connecting strip 16 to rotate. 23 rotates, thereby driving the sealing ring 25 to rotate, thereby driving the first partition plate 26 to rotate, so that the first through groove 27 can be moved to different positions to communicate with different areas, thereby supplying air to different areas, and when the UAV 1 flies sideways, the first through groove 27 changes position synchronously with the rotating block 11, so that the UAV 1 always keeps supplying air to the high-pressure nozzle 35 in the flight direction, so that the high-pressure nozzle 35 can always spray gas in the flight direction, thereby improving the flexibility and adaptability of the device, thereby improving the stability of the flight of the wounded transport pod 4, thereby improving the overall practicality of the device.

[0054] When the UAV 1 performs a dive or a pitch operation, the PLC controller controls the hydraulic cylinder 13 to start, and drives the hydraulic cylinder 13 to rotate while driving the fourth connecting pipe 39 to rotate. Under the action of the fixing rod 36, the high-pressure nozzle 35 can always maintain a parallel position with the UAV 1, so that when the UAV 1 changes its angle, the high-pressure nozzle 35 can change its angle at the same time, so that the gas ejected by the high-pressure nozzle 35 is always kept consistent with the flight direction, so that the high-pressure nozzle 35 can adapt to different flight angles and directions for gas injection, thereby further improving the stability of the flight of the wounded transport pod 4, thereby improving the overall practicality of the device.

[0055] The workflow of the technical solution provided by the present invention is as follows:

[0056] When in use, an angle sensor for detecting the flight angle of the drone 1 is installed inside the drone 1. The hydraulic cylinder 13 is controlled by the PLC controller, and the hydraulic cylinder 13 can be controlled to start intermittently. When the drone 1 changes its flight attitude from flying straight ahead to flying obliquely forward and upward, when the angle sensor senses the tilt angle of the drone 1, the hydraulic cylinder 13 is controlled to start by the PLC controller, and the output end of the hydraulic cylinder 13 controls the driving rotating block 11 to move downward, thereby driving the first rotating rod 7 to move downward, thereby driving the second connecting seat 41 to rotate under the action of the first rotating rod 7, thereby driving the limit block 10 to rotate, so that the spherical rod 6 can rotate with the connecting plate 9, so that the wounded transport pod 4 can rotate, so that when the drone 1 changes its flight attitude to fly obliquely upward, the wounded transport pod 4 can change the angle with the drone 1, so as to always remain in a horizontal state, thereby realizing that when the drone 1 changes its flight attitude, the wounded transport pod 4 can be automatically adjusted, thereby reducing the discomfort or injury that may be caused by the change in flight attitude, thereby ensuring the safety and comfort of the wounded, thereby improving the overall practicality of the device.

[0057] The first drive motor 16 is controlled by a PLC controller, and the first drive motor 16 can be controlled to start intermittently. When the UAV 1 is initially flying sideways, and the flight attitude of the UAV 1 changes from sideways flight to oblique flight to the side and upward, the output end of the first drive motor 16 drives the spur gear 17 to rotate, thereby driving the ring gear 18 to rotate, thereby driving the connecting ring 15 to rotate, and when the rotating block 11 rotates to the forward direction of the UAV 1, the rotating block 11 stops rotating. At this time, the PLC controller controls the hydraulic cylinder 13 to start and drive the first rotating rod 7 to move downward, thereby pushing the wounded transport pod 4 to rotate in different directions, so that when the UAV 1 flies obliquely in different directions, the wounded transport pod 4 can rotate in different directions, so that the wounded transport pod 4 can automatically adjust the angle and direction of the transport pod according to the change of the flight attitude of the UAV 1, thereby improving the adaptability and flexibility of the device, thereby improving the comfort of the wounded when transporting the wounded, reducing the harm to the wounded, and thus improving the overall practicality of the device.

[0058] The second drive motor 20 is controlled by a PLC controller, which can control the intermittent start of the second drive motor 20. When the hydraulic cylinder 13 drives the wounded transport pod 4 to rotate, the PLC controller controls the second drive motor 20 to start, and the output end of the second drive motor 20 drives the second rotating rod 21 to rotate, thereby winding the connecting steel rope 22, thereby synchronously stretching the wounded transport pod 4 while the wounded transport pod 4 rotates, thereby further enhancing the stability of the wounded transport pod 4, so that the wounded transport pod 4 can always remain stable when the drone 1 is diving or rising, thereby improving the riding comfort of the wounded, thereby improving the overall stability of the device.

[0059] The four second drive motors 20 are individually controlled by a PLC controller to reel in or release.

[0060] The air pump 28 is controlled by a PLC controller, which can control the intermittent start of the air pump 28. The air supply hole at one end of the air pump 28 is connected to the air supply device inside the wounded transport pod 4, so that air can be supplied to the inside of the air pump 28. When the hydraulic cylinder 13 drives the rotating block 11 to move downward, so that the wounded transport pod 4 can be adaptively rotated, the PLC controller controls the air pump 28 to start, and the output end of the air pump 28 supplies air to the inside of the first partition plate 26, thereby entering the inside of the second connecting pipe 31 through the first through groove 27 and the second through groove 30, so that the gas can enter the inside of the multiple high-pressure nozzles 35, and spray gas to the outside through the multiple high-pressure nozzles 35, so as to offset the turbulence in the flight of the drone 1 and reduce the flight resistance of the wounded transport pod 4, thereby improving the flight stability of the wounded transport pod 4, thereby improving the overall practicality of the device.

[0061] The second partition plate 32 and the first partition plate 26 divide the inner side of the sealing ring 25 into four areas, and the four areas are respectively connected to the second connecting pipes 31 in four directions. When the drone 1 flies forward, the first through groove 27 is connected to the front area, and the air pump 28 can directly supply the gas from the front area to the second connecting pipe 31 when supplying gas, so that the gas can be sprayed in the flight direction by the high-pressure nozzle 35. At the same time, when the drone 1 changes the flight direction, the PLC controller controls the first drive motor 16 to start, and the output end of the first drive motor 16 drives the rotating plate 12 to rotate, and can drive the connecting strip 16 to rotate. 23 rotates, thereby driving the sealing ring 25 to rotate, thereby driving the first partition plate 26 to rotate, so that the first through groove 27 can be moved to different positions to communicate with different areas, thereby supplying air to different areas, and when the UAV 1 flies sideways, the first through groove 27 changes position synchronously with the rotating block 11, so that the UAV 1 always keeps supplying air to the high-pressure nozzle 35 in the flight direction, so that the high-pressure nozzle 35 can always spray gas in the flight direction, thereby improving the flexibility and adaptability of the device, thereby improving the stability of the flight of the wounded transport pod 4, thereby improving the overall practicality of the device.

[0062] When the UAV 1 performs a dive or a pitch operation, the PLC controller controls the hydraulic cylinder 13 to start, and drives the hydraulic cylinder 13 to rotate while driving the fourth connecting pipe 39 to rotate. Under the action of the fixing rod 36, the high-pressure nozzle 35 can always maintain a parallel position with the UAV 1, so that when the UAV 1 changes its angle, the high-pressure nozzle 35 can change its angle at the same time, so that the gas ejected by the high-pressure nozzle 35 is always kept consistent with the flight direction, so that the high-pressure nozzle 35 can adapt to different flight angles and directions for gas injection, thereby further improving the stability of the flight of the wounded transport pod 4, thereby improving the overall practicality of the device.
