Description

Technical Field

[0001] This invention relates to the field of rescue helicopter technology, specifically to a multi-rotor rescue platform mounted on a rescue helicopter. Background Technology

[0002] Rescue helicopters are used for emergency rescue (air ambulance services), enabling them to reach work sites inaccessible by land or water more quickly. They conduct search and rescue operations, transport supplies, and provide aerial command, and are widely used in many countries worldwide as one of the most effective emergency rescue methods. Helicopters are the core equipment for aviation emergency rescue. During flight, the rotor generates both lift and thrust. Helicopters can be classified as single-rotor or multi-rotor, and are a crucial component of the helicopter.

[0003] For example, the multi-functional emergency rescue drone with publication number CN216035143U includes a fuselage, wings, and a drive unit. The wings are connected to the fuselage and driven to rotate by the drive unit, which is located on the wings. It also includes a loading platform and a camera arranged side by side in the horizontal direction. A fixed plate is provided on the lower end face of the fuselage. The loading platform, which is equipped with emergency rescue supplies, is detachably connected to the fixed plate. The camera is rotatably connected to the fixed plate through a rotating bracket. This application achieves multiple functions of the drone by flexibly assembling the loading platform with different loading platform structures and detachable connection structures between the loading platform and the fuselage, which not only reduces equipment costs but also improves flight stability and payload capacity. It also has the advantages of simple structure and easy use, making it highly practical.

[0004] The aforementioned application employs a rescue method that involves directly loading cargo onto a drone and placing it on a rescue platform. This method carries the risk of the cargo falling off the drone, and the platform is located in the center of the rotor, making it inconvenient for manual handling. Traditional rescue helicopters also use ropes to attach the loading platform, placing it at the bottom of the helicopter. However, due to the instability of the ropes, the platform is prone to twisting, making it difficult to ensure the stability of the loaded items. Furthermore, the items are prone to friction with the ground during placement, affecting the quality of the products. Therefore, the method has limitations.

[0005] Therefore, we propose a multi-rotor rescue platform mounted on a rescue helicopter to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-rotor rescue platform mounted on a rescue helicopter, in order to solve the problem mentioned in the background art that the platform is prone to twisting due to the instability of the ropes, making it difficult to ensure the stability of the carried items.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-rotor rescue platform mounted on a rescue helicopter, comprising a support mechanism and a mounting mechanism installed on the support mechanism;

[0008] The support mechanism includes a support frame, an extension plate fixedly installed on the outer periphery of the support frame, and a load-bearing frame fixedly installed at the lower end of the support frame;

[0009] A first connecting block is fixedly installed at one end of the extension plate, and a second connecting block is fixedly installed at the lower end of the extension plate.

[0010] The support mechanism is equipped with lifting mechanisms on all four sides. The lifting mechanism includes a lifting wheel, a lifting rope slidably installed on the lifting wheel, and a rotating roller fixedly installed on one end of the lifting rope. One end of the lifting rope is fixedly connected to the upper end of the support frame.

[0011] The support mechanism is also surrounded by a stabilizing mechanism. The stabilizing mechanism includes a first connecting rod rotatably connected to the first connecting block and a second connecting rod rotatably connected to one side of the first connecting rod. One end of the second connecting rod is also rotatably connected to the second connecting block, and one end of the first connecting rod is rotatably connected to the rotating roller.

[0012] The mounting mechanism includes a mounting plate installed on the load-bearing frame, an overflow hole opened on the mounting plate, and a suspension plate fixedly installed at the lower end of the mounting plate.

[0013] The lifting mechanism further includes a roller fixedly installed at the lower end of the lifting rope, a fixed shaft rotatably installed at one end of the roller, and a first stabilizing rod fixedly installed between the two rollers. The fixed shaft is fixedly installed on the extension plate. A pulley is coaxially provided at one end of the roller. A belt body is rotatably installed between the two pulleys. One end of one of the pulleys is connected to a first motor.

[0014] The second connecting rod includes a first support rod rotatably connected to one side of the second connecting block, a second support rod fixedly installed on one side of the first support rod, and one end of the second support rod fixedly installed on a third support rod, wherein one end of the third support rod is rotatably connected to one side of the first connecting rod.

[0015] The angle between the first support rod and the second support rod is smaller than the angle between the second support rod and the third support rod. After the device is lifted by a helicopter, the first support rod is set perpendicular to the second connecting block.

[0016] The second connecting block and the first support rod are connected by a first elastic element, and two adjacent first connecting rods are connected by a second stabilizing rod.

[0017] The lower end of the stabilizing mechanism is provided with an anti-slip mechanism, which includes a sliding plate. The sliding plate is fixedly installed at the lower end between the second support rod and the third support rod. Both ends of the sliding plate are suspended in the air. The sliding plate and the second support rod are connected by a second elastic element.

[0018] The lower end of the support mechanism is also provided with a buffer mechanism, which includes a crossbar and buffer rings fixedly installed at both ends of the crossbar. A telescopic rod is installed between the crossbar and the load-bearing frame. A third elastic element is sleeved on the outer periphery of the telescopic rod. An airbag is fixedly installed in the middle of the buffer ring. The airbag has a ring structure.

[0019] A drive mechanism is also provided on one side of the buffer mechanism. The drive mechanism includes a support frame fixedly installed inside the airbag and an electromechanical box installed inside the support frame.

[0020] The electromechanical box contains a second motor, the output of which is connected to a shaft, and a propeller is fixedly mounted on one end of the shaft.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The cargo is secured to the mounting mechanism, which is fixedly connected to the helicopter via four lifting ropes. These four ropes act on the extension plate, overcoming the shortcomings of existing single-rope fixation. This increases lifting strength while reducing the possibility of rope twisting, ensuring cargo stability. Through the cooperation between the lifting ropes, the first connecting rod, and the second connecting rod, the lifting ropes form a triangular structure after lifting, increasing the force-bearing area of ​​the device and further enhancing its stability. This solves the problem mentioned in the background technology where the platform is prone to twisting due to the instability of the ropes, making it difficult to ensure the stability of the loaded goods.

[0023] 2. After the first motor is turned on, the roller can rotate, and the number of turns of the lifting rope can be adjusted, which facilitates the adjustment of the height of the loading platform and the loading of goods. It is highly flexible, and the four lifting ropes can rotate at the same time, ensuring that multiple lifting ropes are wound at the same time, thus ensuring the stability of the loading platform adjustment.

[0024] 3. Through the cooperation between the lifting rope, the first connecting rod, and the second connecting rod, when the mounting plate is lowered, the first elastic element resets, which in turn drives the first connecting rod and the second connecting rod to reset. This causes the corners of the first and second support rods to support the ground, and the corners of the second and third support rods to contact the bottom of the suspension plate. This increases the height of the mounting plate and reduces the impact caused by the mounting plate directly contacting the ground, resulting in a good cushioning effect. After the mounting plate is raised, the height difference between the mounting plate and the support frame is reduced, making it easier to load and unload goods.

[0025] 4. After the cargo lands, the buffer ring and airbag first contact the ground, which plays an initial role in cushioning. When conducting water rescue, the airbag can make the device float on the water surface, reducing the device's sinking. This device can be used in both water and land and is suitable for various environments.

[0026] 5. During water rescue operations, a second motor can be activated, which can drive the shaft and propeller to rotate. If the device is unfortunately separated from the helicopter, it can drive the propeller to rotate, allowing the device to travel independently and increasing the success rate of the rescue.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1-6 The present invention provides a technical solution: a multi-rotor rescue platform mounted on a rescue helicopter, including a support mechanism 1 and a carrying mechanism 2 mounted on the support mechanism 1. The support mechanism 1 is mounted on the lower end of the helicopter, and the carrying mechanism 2 is mounted on the lower end of the support mechanism 1 for carrying cargo.

[0039] The support mechanism 1 includes a support frame 11, an extension plate 12 fixedly installed on the outer periphery of the support frame 11, and a load-bearing frame 13 fixedly installed on the lower end of the support frame 11. The mounting mechanism 2 is installed on the load-bearing frame 13. The height of the support frame 11 is higher than that of the load-bearing frame 13, and it is used to limit the movement of the goods.

[0040] One end of the extension plate 12 is fixedly installed with a first connecting block 14, and the lower end of the extension plate 12 is fixedly installed with a second connecting block 15.

[0041] The support mechanism 1 is equipped with lifting mechanisms 3 on all four sides. The lifting mechanism 3 includes a lifting wheel 31, a lifting rope 32 slidably installed on the lifting wheel 31, and a rotating roller 33 fixedly installed on one end of the lifting rope 32. One end of the lifting rope 32 is fixedly connected to the upper end of the support frame 11.

[0042] The cargo is secured to the mounting mechanism 2 and located inside the support frame 11. The lifting wheel 31 of this device is fixedly installed at the lower end of the multi-rotor helicopter. The four lifting ropes 32 are respectively fixed to the extension plates 12 around the support frame 11. After lifting, the four lifting ropes 32 act on the extension plates 12 respectively, which improves the shortcomings of the existing single rope fixation. While increasing the lifting strength, it also reduces the possibility of the lifting ropes 32 twisting, ensuring the stability of the cargo.

[0043] The support mechanism 1 is also provided with a stabilizing mechanism 4 around it. The stabilizing mechanism 4 includes a first connecting rod 41 rotatably connected to the first connecting block 14 and a second connecting rod 42 rotatably connected to one side of the first connecting rod 41. One end of the second connecting rod 42 is also rotatably connected to the second connecting block 15, and one end of the first connecting rod 41 is rotatably connected to the rotating roller 33.

[0044] In the initial state, the end of the first connecting rod 41 away from the first connecting block 14 rests on the ground, which serves as a support for the device, suspending the load-bearing frame 13 on the ground and reducing friction. One end of the lifting rope 32 is rotatably connected to the first connecting rod 41 through the rotating roller 33. After lifting, the first connecting rod 41 rotates around the first connecting block 14.

[0045] After rotating to a certain angle, one end of the first connecting rod 41 abuts against one side of the first connecting block 14, limiting the maximum rotation angle of the first connecting rod 41. After rotation, the lifting rope 32 has a triangular structure, which increases the force-bearing area of ​​the device and further increases the stability of the device.

[0046] Example 2: Please refer to Figures 4-6 The mounting mechanism 2 includes a mounting plate 21 mounted on the load-bearing frame 13, an overflow hole 22 opened on the mounting plate 21, and a suspension plate 23 fixedly mounted on the lower end of the mounting plate 21.

[0047] The suspension plate 23 is located at the upper end of the load-bearing frame 13, and the mounting plate 21 is located inside the support frame 11. Its height is lower than that of the support frame 11. The mounting plate 21 has an embedded structure, which facilitates the protection of the outer perimeter of the cargo. By opening the overflow hole 22, the water accumulation on the mounting plate 21 is reduced. By setting the suspension plate 23, when water rescue is carried out, the mounting plate 21 can be suspended on the water surface under the action of the suspension plate 23, which to a certain extent prevents the sinking of the device and its cargo.

[0048] The lifting mechanism 3 also includes a roller 34 fixedly installed at the lower end of the lifting rope 32, a fixed shaft 38 rotatably installed at one end of the roller 34, and a first stabilizing rod 35 fixedly installed between the two rollers 34. The fixed shaft 38 is fixedly installed on the extension plate 12. A pulley 36 is coaxially provided at one end of the roller 34. A belt body 37 is rotatably installed between the two pulleys 36. One end of one of the pulleys 36 is connected to a first motor 39.

[0049] One end of the lifting rope 32 is wound around the roller 34. After the first motor 39 is turned on, the roller 34 can rotate, and the number of turns of the lifting rope 32 can be adjusted. The more turns, the shorter the lifting rope 32. Therefore, the support mechanism 1 and the mounting mechanism 2 are closer to the helicopter, and vice versa. This makes it easier to adjust the height of the mounting plate 21, facilitates the loading of goods, and provides high flexibility.

[0050] The two lifting ropes 32 are connected together by pulleys 36 and belt body 37. The two adjacent lifting ropes 32 are also connected together by rollers 34 and first stabilizing rods 35, so that the four lifting ropes 32 can rotate at the same time, ensuring that multiple lifting ropes 32 are wound around at the same time, thus ensuring the stability of the adjustment of the mounting plate 21.

[0051] Example 3: Please refer to Figures 5-7 The second connecting rod 42 includes a first support rod 421 rotatably connected to one side of the second connecting block 15, a second support rod 422 fixedly installed on one side of the first support rod 421, and one end of the second support rod 422 fixedly installed on a third support rod 423. One end of the third support rod 423 is rotatably connected to one side of the first connecting rod 41.

[0052] The angle between the first support rod 421 and the second support rod 422 is smaller than the angle between the second support rod 422 and the third support rod 423. The second connecting block 15 and the first support rod 421 are connected by a first elastic element 43. The two adjacent first connecting rods 41 are connected by a second stabilizing rod 44.

[0053] The first support rod 421, the second support rod 422, and the third support rod 423 are combined to form a bent structure. After lifting, the first connecting rod 41 rotates upward, and the corners of the first support rod 421 and the second support rod 422 are set outward. The first support rod 421 is set perpendicular to the second connecting block 15. The angle between the first support rod 421 and the second support rod 422 is higher than the angle between the second support rod 422 and the third support rod 423. The first elastic element 43 is in a compressed state to increase the force-bearing area of ​​the lifting rope 32.

[0054] The lower end of the stabilizing mechanism 4 is provided with an anti-slip mechanism 5, which includes a sliding plate 51. The sliding plate 51 is fixedly installed at the lower end between the second support rod 422 and the third support rod 423. Both ends of the sliding plate 51 are suspended. The sliding plate 51 and the second support rod 422 are connected by a second elastic element 52.

[0055] When the mounting plate 21 is lowered, the sliding plate 51 first contacts the ground, increasing the contact area with the ground and ensuring the stability of the landing. The second elastic element 52 acts as a buffer for both ends of the sliding plate 51.

[0056] After landing, the lifting rope 32 loses its tension, the first connecting rod 41 loses its restraint from the lifting rope 32, and the first elastic element 43 resets, causing the first connecting rod 41 and the second connecting rod 42 to reset as well. This allows the corners of the first support rod 421 and the second support rod 422 to support the ground, increasing the height of the support mechanism 1 of this device. The corners of the second support rod 422 and the third support rod 423 contact the bottom of the suspension plate 23, increasing the height of the mounting plate 21. After the mounting plate 21 is raised, the extent of the raising of the mounting plate 21 is greater than the extent of the raising of the support frame 11, reducing the height difference between the mounting plate 21 and the support frame 11, which facilitates the loading and unloading of goods.

[0057] Furthermore, when the ground is uneven or there is standing water, the support frame 11 and the mounting plate 21 are raised, reducing the impact caused by the mounting plate 21 directly contacting the ground, resulting in a good buffering effect.

[0058] Example 4: Please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 The lower end of the support mechanism 1 is also provided with a buffer mechanism 6. The buffer mechanism 6 includes a crossbar 61 and a buffer ring 62 fixedly installed at both ends of the crossbar 61. A telescopic rod 63 is installed between the crossbar 61 and the load-bearing frame 13. A third elastic element 64 is sleeved on the outer periphery of the telescopic rod 63. An airbag 65 is fixedly installed in the middle of the buffer ring 62. The airbag 65 has a ring structure.

[0059] After the cargo lands, the buffer ring 62 and airbag 65 first come into contact with the ground, providing initial cushioning. At the same time, in conjunction with the third elastic element 64 and telescopic rod 63, the cushioning effect of the device is further enhanced.

[0060] When conducting water rescue operations, the device can be suspended on the water surface by setting up the airbag 65, reducing the device's sinking and making it suitable for both water and land use, as well as various environments.

[0061] During water rescue operations, the 51 skateboard glides on the water's surface, adapting to the undulating shape of the waves, further enhancing its anti-sinking function.

[0062] Example 5: Please refer to Figures 8-9 A drive mechanism 7 is also provided on one side of the buffer mechanism 6. The drive mechanism 7 includes a support frame 71 fixedly installed inside the airbag 65 and an electromechanical box 72 installed inside the support frame 71.

[0063] The second motor 73 is installed inside the electromechanical box 72. The output end of the second motor 73 is connected to the rotating shaft 74, and a propeller 75 is fixedly installed at one end of the rotating shaft 74.

[0064] During water rescue operations, the second motor 73 can be activated, which can drive the shaft 74 and propeller 75 to rotate. If the device is unfortunately separated from the helicopter, it can drive the propeller 75 to rotate, thus enabling the device to operate independently and increasing the success rate of the rescue.

[0065] Working principle: The cargo is fixed on the mounting mechanism 2 and located inside the support frame 11. The lifting wheel 31 of this device is fixedly installed at the lower end of the multi-rotor helicopter. The four lifting ropes 32 are respectively fixed on the extension plates 12 around the support frame 11. After lifting, the first connecting rod 41 rotates around the first connecting block 14 as the center, and the first elastic element 43 is stretched.

[0066] After landing, the hoisting rope 32 loses its tension, the first connecting rod 41 is no longer restrained by the hoisting rope 32, the first elastic element 43 resets, and drives the first connecting rod 41 and the second connecting rod 42 to reset, so that the corners of the first support rod 421 and the second support rod 422 support the ground, and the corners of the second support rod 422 and the third support rod 423 contact the bottom of the suspension plate 23, raising the mounting plate 21.

[0067] During water rescue operations, the airbag 65 suspends the device on the water surface, and the skateboard 51 glides on the water surface, adapting to the undulating shape of the waves. The second motor 73 is activated, which drives the rotating shaft 74 and the propeller 75 to rotate. If the device unfortunately detaches from the helicopter, it can travel independently.
