Description

Technical Field

[0001] The invention relates to the technical field of rescue simulation, in particular to a helicopter rescue simulation device. Background Art

[0002] As an efficient and rapid means of emergency response, helicopter rescue plays an irreplaceable role in various emergency situations such as natural disasters, medical emergency, mountain search and rescue, etc. It relies on the vertical take-off and landing and high-speed flight capabilities of helicopters to quickly reach remote or inaccessible areas and provide timely assistance to trapped people;

[0003] With the continuous development of helicopter rescue technology, professional training for rescuers has also received increasing attention. The helicopter rescue simulator has emerged as the times require. It is a training device that can simulate the real scene of helicopter rescue. It aims to improve the professional skills and emergency response capabilities of rescuers through a highly simulated environment.

[0004] The importance of helicopter rescue simulation training for rescuers is self-evident. First of all, helicopter rescue missions are often accompanied by extremely high risks and uncertainties. Rescuers need to make quick judgments and take actions in a complex and changing environment. Through simulation training, rescuers can practice repeatedly in a safe environment, so as to master various rescue skills and response strategies, improve rescue efficiency, and reduce operational risks.

[0005] However, traditional helicopter rescue simulators have obvious limitations. Due to terrain restrictions, safety considerations, time constraints, weather factors and other reasons, helicopters are sometimes unable to find a suitable landing point and need to hover in the air for rescue. In this case, rescuers need to use ropes to descend from the hovering helicopter to the ground for rescue. However, traditional simulators can only simulate operations within the cabin, but cannot conduct real and effective simulation training for external rope suspension and rappelling. As a result, when faced with actual rappelling tasks, rescuers may feel overwhelmed due to lack of sufficient training and experience, and cannot meet the current needs of rescuers to improve their skills.

[0046] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0047] When in use, the simulated cabin 7 is lowered to a suitable height by using the crane 3, and the rescue personnel enter the inner cavity of the simulated cabin 7 and tie the safety rope 11 to ensure the safety of the rescue personnel. The simulated cabin 7 is raised by using the crane 3 until it is raised to a suitable height, and the fourth motor 61 is started. The first bevel gear 63 and the second propeller 67 are driven to rotate by the fourth motor 61 through the third connecting rod 62. The rotation of the first bevel gear 63 can drive the second bevel gear 65 to rotate through the third bevel gear 610, and the rotation of the second bevel gear 65 can drive the first propeller 66 to rotate in the opposite direction of the second propeller 67 through the sleeve 64, so as to simulate a helicopter. The effect of the rotation of the helicopter propeller on the air pressure, the rescue personnel perform rappelling and suspension simulation training through the rope 10, use the electric hoist 9 to drive the rescue personnel to rise and fall through the rope 10, start the first motor 46, use the first motor 46 to drive the sprocket 48 to rotate through the first connecting rod 47, so that the sprocket 48 drives the chain 49 to move circumferentially, and the circumferential movement of the chain 49 can drive the sliding column 410 to move along the movement trajectory of the chain 49, so that the cooperation between the sliding column 410 and the driving groove 54 that moves in the circumferential direction can drive the simulated cabin 7 to move left and right through the slide plate 51, thereby simulating the flight of the helicopter, and the crane 3 drives the simulated cabin 7 to move The lifting and landing of the helicopter can be simulated. For example, when the rescue personnel need to rappel and carry heavy objects to lift up, due to the increase in the weight of the simulated cabin 7, the two connecting rods 59 will be used to pull the moving block 58 to move to the inner side of the inner cavity of the moving groove 55, and the spring 57 will be squeezed to undergo elastic deformation, thereby simulating the bumps caused by the helicopter under the gravity factor. The second motor 511 is started, and the output end of the second motor 511 is used to drive the worm 512 to rotate. The rotation of the worm 512 can prompt the worm wheel 518 to drive the second rotating frame 519 to rotate through the first rotating rod 517, thereby driving the simulated cabin 7 to rotate with the first rotating rod 517 as the center of the circle. The second motor 511 is started. Three motors 513 are used, and the output end of the third motor 513 is used to drive the first rotating frame 516 to rotate through the second connecting rod 514, so that the first rotating frame 516 can be used to drive the worm wheel 518 and the second rotating frame 519 to rotate with the second connecting rod 514 as the center through the first rotating rod 517. Since the second connecting rod 514 and the worm 512 are concentric, the worm wheel 518 is caused to rotate around the worm 512 with the worm 512 as the center. At the same time, the second rotating frame 519 can drive the simulated cabin 7 to rotate with the second connecting rod 514 as the center, so that the turbulence caused by helicopter flight, take-off, landing and hovering can be simulated through multi-angle rotation.

[0048] To sum up, the present invention can simulate real scenes to train rescue personnel in skills such as rappelling and hanging. The device effectively makes up for the shortcomings of traditional helicopter rescue simulation training, allowing rescue personnel to repeatedly practice complex and changeable external rescue skills in a highly simulated environment, significantly improving their ability to cope with high-risk and uncertain rescue tasks. It not only improves rescue efficiency and safety, but also ensures that rescue personnel can remain calm and accurately implement policies when facing actual hovering rescue challenges, and better serve various emergency rescue needs such as natural disasters, medical first aid and mountain search and rescue.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
