Description

Technical Field

[0001] The present invention particularly relates to a simulation training device for helicopter rescue. Background Art

[0002] Helicopter rescue, as an emergency rescue method that integrates multidisciplinary elements such as aviation technology, medical first aid, and environmental adaptability, has been widely used in diverse scenarios such as search and rescue in mountain canyons, transfer of injured and sick people in offshore oil wells, and fire rescue in urban high-rise buildings due to its advantages of rapid response, long-distance mobility, and strong adaptability to complex terrain.

[0003] In today's era of frequent natural disasters, helicopter rescue has become a crucial force in emergency missions, such as detecting life in earthquake debris, evacuating people from isolated flood-affected islands, and providing aerial support for forest fires. Its operational effectiveness is directly related to the safety of victims and the success of rescue operations. However, the helicopter rescue environment is complex and volatile, and rescuers face numerous challenges, including the risks of working at height, helicopter sway and vibration, and strong winds. Therefore, rigorous and comprehensive simulation training is essential.

[0004] Existing helicopter rescue simulation training devices primarily focus on simulating high-altitude environments. For example, they use lifting equipment to simulate a helicopter's hovering altitude and utilize virtual reality technology to present rescue scenarios. However, these devices have significant shortcomings. Most can only simulate high-altitude rescues, but cannot simulate the swaying and vibrations of a real rescue environment, or the interference caused by air vortexes when helicopter blades rotate, resulting in reduced training effectiveness. In light of this, a helicopter rescue simulation training device is proposed to address these issues. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention proposes a simulation training device for helicopter rescue to solve the technical problem that most of the existing simulation training devices proposed in the above background technology can only simulate high-altitude rescue, but cannot simulate the interference of shaking, vibration and air vortex when helicopter blades rotate in a real rescue environment, thereby reducing the training effect.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a helicopter rescue simulation training device, comprising: A support frame, one side of which is provided with a simulation frame connected by a mounting frame, and a top of which is provided with a mounting frame, wherein the mounting frame is provided with a blade driven to rotate by a driving motor; A support bracket is slidably disposed on the mounting frame and connected to the blade via a driving mechanism, wherein the driving mechanism converts the rotation of the blade into driving the support bracket to slide back and forth; A connecting frame is escalably mounted on the supporting frame, and a rescue rope connected to the bottom of the connecting frame is provided via a winding machine; and The vibration mechanism is arranged on the installation frame and connected to the connecting frame to convert the sliding of the supporting frame into driving the connecting frame to vibrate.

[0009] In a preferred embodiment, a positioning rod is provided on the installation frame, and sliding sleeves are provided at both ends of the support bracket, and the sliding sleeves are slidably provided on the positioning rod.

[0010] In a preferred embodiment, the driving mechanism includes: A drive plate rotatably disposed on the mounting frame along its axis; a transmission assembly, disposed on the blade and connected to the drive disc, so as to convert the rotation of the blade into driving the drive disc to rotate; and A driving rod has one end eccentrically hinged to the driving disc and the other end hinged to the supporting bracket.

[0011] In a preferred embodiment, the transmission assembly includes: a worm, one end of which is connected to the output shaft of the drive motor, and the blade is arranged on the worm; and The worm wheel is rotatably arranged on the installation frame along its axis and is engaged with the worm.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0020] Example: like Figures 1 to 3 As shown, the present invention provides a helicopter rescue simulation training device, comprising a support frame 1, with a simulation frame 6 connected to one side via a mounting frame 5. A protective net 2 is also provided on the support frame 1, with both ends of the protective net 2 connected to the support frame 1 via a cable 3. A climbing frame 4 is also provided on one side of the support frame 1. A mounting frame 7 is provided on the top of the support frame 1, with blades 15 driven for rotation by a drive motor 13 mounted on the mounting frame 7. A support bracket 21 is provided on the mounting frame 7, with a connecting bracket 25 provided on the supporting bracket 21 in a manner that allows it to be raised and lowered. A rescue rope 28 connected via a winder 27 is provided at the bottom of the connecting bracket 25.

[0021] During simulation training using this device, trainees can climb to the top of the support frame 1 via the climbing frame 4 and pull the rescue rope 28 to conduct rescue training. Simulation frame 6 can be used to simulate various scenarios, such as thick smoke and fire, with a dummy placed inside awaiting rescue, enhancing the realism of the simulation. A protective net 2 can also be used to protect trainees, enhancing safety during use of the device. The drive motor 13 can be used to drive the blades 15 to rotate, simulating the gas flow in a real helicopter rescue environment.

[0022] like Figure 4 、 5As shown, in this embodiment, the support bracket 21 is slidably disposed on the mounting frame 7 and is connected to the paddle 15 via a drive mechanism. The drive mechanism converts the rotation of the paddle 15 into reciprocating sliding movement of the support bracket 21. The drive mechanism includes a drive disk 17 rotatable along its axis and disposed on the mounting frame 7. The paddle 15 is provided with a transmission assembly connected to the drive disk 17. The transmission assembly converts the rotation of the paddle 15 into controlled rotation of the drive disk 17. One end of the drive rod 20 is eccentrically hinged to the drive disk 17, and the other end is hinged to the support bracket 21. The transmission assembly includes a worm 14 and a worm wheel 16. One end of the worm 14 is connected to the output shaft of the drive motor 13. The paddle 15 is disposed on the worm 14. The worm wheel 16 is rotatable along its axis and engaged with the worm 14 on the mounting frame 7. The drive disk 17 is disposed on the worm wheel 16.

[0023] It is understood that in some embodiments, the mounting frame 7 is provided with a first support plate 9 and a second support plate 10 arranged at intervals, the paddle 15 is rotatably provided on the first support plate 9, the worm gear 16 is rotatably provided on the second support plate 10, and the drive motor 13 is fixedly provided at the bottom of the second support plate 10, the paddle 15 is stably supported by the first support plate 9, and the worm 14, the worm gear 16, and the drive motor 13 are mounted by the second support plate 10. The drive motor 13 can drive the worm 14 to rotate in the process of controlling the rotation of the paddle 15, and then control the rotation of the drive disk 17 by cooperating with the worm gear 16. During the rotation process, the drive disk 17 can control the reciprocating sliding of the support bracket 21 through the drive rod 20, and a positioning rod 8 is provided on the mounting frame 7, and a sliding sleeve 22 is provided at each end of the support bracket 21. The sliding sleeve 22 is slidably provided on the positioning rod 8, and the sliding of the support bracket 21 is positioned by cooperating with the positioning rod 8, thereby improving the stability of the device during use. The support bracket 21 can drive the rescue rope 28 to swing during the sliding process, so as to simulate the influence caused by the movement of the helicopter or the crosswind, thereby improving the authenticity of the simulation.

[0024] like Figures 4 to 6 As shown, in this embodiment, a slider 19 and a driving portion 18 for driving the slider 19 to slide are slidably provided on one side of the driving disk 17, and one end of the driving rod 20 is hinged to the slider 19. It is understandable that the driving portion 18 can be a telescopic motor or a screw drive structure, and the driving portion 18 drives the slider 19 to slide on one side of the driving disk 17. The farther the slider 19 is from the center of the driving disk 17, the greater the sliding amplitude of the support bracket 21 is controlled, and thus the greater the swing amplitude of the rescue rope 28 is, so as to facilitate the control of the swing amplitude of the rescue rope 28 without affecting the rotation of the blade 15, and facilitate simulated training of different intensities. When the control slider 19 moves to the center position of the driving disk 17, the sliding of the support bracket 21 can be stopped.

[0025] like Figure 3 、 4 As shown in Figures 6 and 7, in this embodiment, a vibration mechanism connected to the connecting frame 25 is provided on the mounting frame 7. The vibration mechanism converts the sliding movement of the support frame 21 into driving the connecting frame 25 to vibrate. The vibration mechanism includes a support rod 11 provided on the mounting frame 7, on which a plurality of groups of protrusions 12 are arranged at intervals. The connecting frame 25 is rotatably provided with running wheels 26, which are mounted on the support rod 11. The connecting frame 25 is also provided with a mounting sleeve 23, within which a hydraulic telescopic rod 24 is disposed. The end of the hydraulic telescopic rod 24 is connected to the bottom surface of the connecting frame 25.

[0026] As the support frame 21 slides, the connecting frame 25 slides with it. The running wheels 26 roll on the support rod 11, which in turn controls the vibration of the connecting frame 25 via the bumps 12, simulating the vibration of the helicopter's internal components during operation and transmitting it to the rescue rope 28. Furthermore, by controlling the hydraulic telescopic rod 24 to raise the connecting frame 25 a certain distance, the vibration simulation or a smaller amplitude of vibration can be canceled, thereby facilitating the control of the vibration intensity during training and expanding the applicability of the training device. Furthermore, the intensity of the multiple simulation modes in this training device can be freely adjusted, enabling both superimposed training of multiple interference factors and targeted training in a single direction, making it suitable for different training groups.

[0027] Specific usage and beneficial effects of the present invention: When the device is in use, rescuers can perform simulated rescue work on the rescue rope 28, and can simulate scenes such as thick smoke and fire in the simulation frame 6, and during the rescue training, the blades 15 can be controlled to rotate by the drive motor 13 to simulate the vortex effect of the wing on the air in a real helicopter rescue environment. During the rotation of the blades 15, the rotation can be converted into a drive support bracket 21 to slide back and forth through the driving mechanism, thereby simulating the shaking of the rescue rope 28 caused by crosswind or the movement of the helicopter in a high-altitude environment, and the sliding of the support bracket 21 can be converted into a drive connection frame 25 to vibrate through the vibration mechanism to simulate the vibration of the helicopter during operation. Through various forms of coordinated simulation, the training scene can be made as close as possible to the real rescue environment, thereby effectively improving the effect of rescue training, enabling rescuers to better perform their duties in real rescue operations, improving rescue efficiency, and reducing casualty rates during rescue.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications and improvements may be made based on the present invention, as will be apparent to those skilled in the art.
