Description

Technical Field

[0001] This invention relates to flight rescue training devices, specifically to a training device for simulating parachute-covered escape. Background Technology

[0002] Current flight rescue training equipment focuses on parachute flight control training and parachute water-dragging escape training, but lacks training equipment for personnel escaping while covered by a parachute during airdrops or catapult launches. Therefore, current parachute escape training is conducted in real-world scenarios, requiring coordination among numerous units, relying on aircraft for training, resulting in high costs, dependence on weather conditions, poor sustainability, and high risks. Summary of the Invention

[0003] The purpose of this invention is to provide a training device for simulating umbrella-covered escape. This device can simulate the scenario of a person escaping while covered by an umbrella during an airdrop or catapult landing in water. It is low in cost, unaffected by external conditions, and highly efficient in training.

[0004] The technical solution adopted in this invention is: A training device simulating parachute escape includes a rotatable cantilever, a human-parachute release system located at the end of the cantilever, and a training parachute. The cantilever is used to rotate and switch the human-parachute release system between a ready position and a landing position. The human-parachute release system includes a main shaft, a human release device, a parachute frame, and a parachute canopy release device. The human release device is located at the lower end of the main shaft and is used to connect to and release hooks on the human shoulder straps under control. The parachute frame is located on the main shaft above the human release device and can be adjusted in terms of deployment degree under control. The parachute canopy release devices are distributed at various outer edge points of the parachute frame and are used to connect to and release hooks on the training parachute under control. On the parachute canopy, hooks corresponding to the parachute canopy release devices are distributed circumferentially near the outer edge of the top surface, and a through hole for the shoulder strap to pass through is provided in the center.

[0005] Preferably, the cantilever, personnel release device, and parachute release device are uniformly controlled by the control system. In the static water-falling mode: the control system first controls the cantilever to rotate so that the personnel-parachute release system switches to the water-falling position, and then controls the personnel release device and parachute release device to release simultaneously or sequentially after a certain delay after a certain delay; or, when the control system controls the cantilever to rotate so that the personnel-parachute release system switches smoothly to the water-falling position, it controls the personnel release device and parachute release device to release simultaneously or sequentially after a certain delay.

[0006] Preferably, the cantilever, personnel release device, and parasol release device are uniformly controlled by the control system. In the drifting and landing mode: when the control system controls the cantilever to rotate rapidly at a set angular velocity so that the personnel-parasol release system quickly switches to the landing position, the personnel-parasol release system reaches the set drift speed. At the same time, the control system controls the personnel release device and parasol release device to release simultaneously.

[0007] Preferably, two sets of training devices for simulating umbrella-covered escape are used, and the two sets are used alternately for training. When one set is used for training, the other set is used for training preparation. At all times, the human-umbrella release system of one set is in the ready position and the human-umbrella release system of the other set is in the water landing position.

[0008] Preferably, the cantilever arms of the two sets of simulated umbrella-covered escape training devices are interlocked, and the cantilever arms have limiting structures at the initial position and the water landing position to prevent the two sets of cantilever arms from interfering with each other.

[0009] Preferably, the umbrella frame includes several umbrella rib units evenly distributed around the main shaft. The umbrella rib unit adopts a linkage structure and has a lower hinge point, an upper hinge point, and an outer edge point. Adjusting the distance between the lower hinge point and the upper hinge point can adjust the degree of expansion of the outer edge point. The lower hinge point of all umbrella rib units is located on the main shaft, and the upper hinge point is located on the sleeve. The sleeve is slidably fitted on the main shaft and is driven to rise and fall by a lifting mechanism.

[0010] Preferably, the lifting mechanism includes a drive component mounted on the main shaft and an adapter component mounted on the sleeve. The drive component is a lockable hydraulic cylinder, pneumatic cylinder, or electric actuator, and the telescopic end of the drive component is connected to the adapter component. Alternatively, the lifting mechanism includes a motor mounted on the main shaft, a lead screw driven by the motor, and a threaded cylinder mounted side by side on the sleeve, with the lead screw and the threaded cylinder threadedly engaged. Alternatively, the lifting mechanism includes a motor mounted on the main shaft, a take-up reel driven by the motor, a lifting line, and an adapter component mounted on the sleeve, with one end of the lifting line wound around the take-up reel and the other end connected downwards to the adapter component.

[0011] Preferably, both the personnel release device and the canopy release device include an unlocking component. The unlocking component is initially in the locked position and can be switched to the unlocked position under electronic control. When the unlocking component is in the locked position, the hook is limited and locked. When the unlocking component is in the unlocked position, the hook automatically disengages.

[0012] Preferably, an adjustment plate is fixedly connected to the upper end of the main shaft. The adjustment plate has connecting holes along the height direction. The adjustment plate is installed at the end of the cantilever by using the connecting holes and bolts.

[0013] Preferably, the cantilever is rotatably mounted on the column, and the cantilever and the column form a cantilever crane, which is installed on the equipment foundation.

[0014] The beneficial effects of this invention are: This device can simulate the escape scenario of personnel being covered by a parachute when airdropped or ejected into water. It is low-cost, unaffected by external conditions, and highly efficient in training. The device is installed next to a pool. During training, the personnel first prepare on the ground or platform, connecting the hooks on the parachute canopy to the respective canopy release devices, and adjusting the parachute frame to the set deployment level. The hooks on the personnel's shoulder straps are then connected to the personnel release devices through the through holes on the parachute canopy. The cantilever then rotates to move the personnel-parachute release system, carrying the personnel and the training parachute, to the water landing position directly above the water surface, and the personnel and parachute release devices are controlled to release. Next, the personnel falls into the water first, followed by the training parachute, which then covers the personnel, allowing them to practice escaping under the parachute cover. After training, the personnel are switched back to the preparation position. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0026] Example 1 This application discloses a training device for simulating umbrella-covered escape, such as... Figure 1 As shown, it includes cantilever 3, a human-parachute release system, and a training parachute; wherein: Cantilever 3 has a rotation function. The man-umbrella release system is located at the end of cantilever 3. The rotation of cantilever 3 can switch the man-umbrella release system between the ready position and the water-launching position. See Figure 1 ; The personnel-parachute release system includes a main shaft 5, a personnel release device 13, a parachute frame 6, and a canopy release device 12. The main shaft 5 is connected to the end of the cantilever 3. The personnel release device 13 is located at the lower end of the main shaft 5. The parachute frame 6 is located on the main shaft 5 above the personnel release device 13. The canopy release devices 12 are distributed at various outer edge points 23 of the parachute frame 6. The personnel release device 13 is used to connect to the hook on the shoulder strap 8 of the personnel 9 and release the hook on the shoulder strap 8 under control. The parachute frame 6 can adjust the degree of deployment under control. The canopy release device 12 is used to connect to the hook of the training parachute and release the hook of the training parachute under control. See [link to documentation]. Figure 1 and Figure 2 ; The training parachute has been modified with the canopy 7 having hooks distributed circumferentially near the outer edge of the top surface and a through hole 24 in the center. The hooks correspond to the canopy release device 12. Figure 5 The hook mounting point 25 corresponds one-to-one with the umbrella release device 12. The through hole 24 is used for the shoulder strap 8 to pass through. Figure 1 and Figure 5 .

[0027] The device is installed next to pool 10. During training: First, in the preparation position on the ground or platform, connect each hook on the training parachute canopy 7 to each canopy release device 12, and adjust the degree of deployment of the parachute frame 6 to adjust the canopy 7 to the set degree of deployment. Then, pass the hook on the shoulder strap 8 of the personnel 9 through the through hole 24 on the training parachute canopy 7 and connect it to the personnel release device 13. Then the cantilever 3 rotates to drive the personnel-parachute release system to switch the personnel 9 and training parachute to the water landing position directly above the water surface, and controls the personnel release device 13 and parachute release device 12 to release; Next, the personnel fell into the water first, and the training parachute then fell into the water and covered personnel 9. Personnel 9 then carried out parachute-covered escape training. After training, switch back to the ready position.

[0028] Therefore, this device can simulate the scenario of people escaping under the umbrella when airdropped or ejected into the water. It is low in cost, unaffected by external conditions, and highly efficient in training.

[0029] Due to considerations of indoor space and civil engineering costs, the training pool 10 is relatively small, and therefore the space available for arranging the training devices for simulating umbrella cover escape is also small. In order to significantly improve training efficiency in a small space, it is preferable to use two sets of training devices for simulating umbrella cover escape, with the two sets being used alternately for training. When one set is used for training, the other set is used for training preparation. The human-umbrella release system of one set is always in the ready position, and the human-umbrella release system of the other set is in the water landing position. Furthermore, the cantilever 3 of the two sets of training devices for simulating umbrella cover escape is interlocked, and the cantilever 3 has a limiting structure at the initial position and the water landing position to prevent the two sets of cantilever 3 from interfering with each other, ensuring that the cantilever 3 does not collide within the rotation range.

[0030] To achieve controlled adjustment and deployment of the umbrella frame 6, this embodiment adopts the following scheme: Figure 2 and Figure 4 As shown, the umbrella frame 6 includes several umbrella rib units evenly distributed around the main shaft. The umbrella rib units adopt a linkage structure. Each umbrella rib unit has a lower hinge point 22, an upper hinge point 21, and an outer edge point 23. Adjusting the distance between the lower hinge point 22 and the upper hinge point 21 can adjust the degree of unfolding of the outer edge point 23. The lower hinge point 22 of all umbrella rib units is located on the main shaft 5, and the upper hinge point 21 is located on the sleeve 11. The sleeve 11 is slidably mounted on the main shaft 5 and is driven to rise and fall by the lifting mechanism. The degree of unfolding of the umbrella frame 6 can be controlled by simply controlling the lifting mechanism.

[0031] Furthermore, regarding the lifting mechanism, it can adopt common mechanical structures. This application provides the following embodiments: The first type, such as Figure 3As shown in a), the lifting mechanism includes a drive component 14 mounted on the main shaft 5 and an adapter component 15 mounted on the sleeve 11. The drive component 14 is a lockable hydraulic cylinder, pneumatic cylinder or electric push rod. The telescopic end of the drive component 14 is connected to the adapter component 15, and the sleeve 11 is lifted and lowered through the telescopic end of the drive component 14.

[0032] The second type, such as Figure 3 As shown in b), the lifting mechanism includes a motor 16 mounted on the main shaft 5, a lead screw 17 driven by the motor 16, and a threaded cylinder 18 mounted side by side on the sleeve 11. The lead screw 17 and the threaded cylinder 18 are threadedly engaged, and the sleeve 18 is lifted and lowered by the threaded transmission driven by the motor 16.

[0033] The third type, such as Figure 3 As shown in c), the lifting mechanism includes a motor 16' mounted on the main shaft 5, a take-up reel 19 driven by the motor 16', a suspension line 20, and an adapter 15' mounted on the sleeve 11. One end of the suspension line 20 is wound around the take-up reel 19, and the other end is connected downward to the adapter 15'. The motor 16' drives the take-up reel 19 to take up and release the suspension line 20, thereby driving the sleeve 11 to rise and fall. This type of lifting mechanism relies on the gravity of the sleeve 11 and its components during the descent of the sleeve 11.

[0034] In this application, both the personnel release device 13 and the parasol release device 12 are used to release the hook under control. The key point is that the release timing is controlled by the control system. Their hardware structure can adopt a conventional structure: both the personnel release device 13 and the parasol release device 12 include an unlocking component. The unlocking component is initially in the locked position and can be switched to the unlocked position under electronic control. When the unlocking component is in the locked position, the hook is limited and locked. When the unlocking component is in the unlocked position, the hook automatically disengages. There are many such conventional structures, and examples will not be given here.

[0035] To ensure a better hooking posture in the ready position, a height adjustment function can be introduced: such as... Figure 1 and Figure 2 As shown, the upper end of the spindle 5 is fixedly connected to the height adjustment plate 4. The height adjustment plate 4 has connecting holes along the height direction. The height adjustment plate 4 is installed at the end of the cantilever 3 by using the connecting holes and bolts. The height of the spindle 5 can be adjusted by selecting different connecting holes.

[0036] Cantilever 3 can be designed and installed separately; however, for convenience, a prefabricated cantilever crane can be used, such as... Figure 1 As shown, the cantilever 3 is rotatably mounted on the column 2, and the cantilever 3 and the column 2 together form a cantilever crane, which is installed on the equipment foundation 1.

[0037] Example 2 This application discloses another training device for simulating umbrella cover escape. In this embodiment, the cantilever 3, personnel release device 13 and umbrella release device 13 are uniformly controlled by the control system, and the observer issues control commands on the operating table next to the pool 10 or on a remote computer.

[0038] The control system can execute two modes depending on the intensity of the training: The first type is the basic static water-falling mode. In the static water-falling mode: The control system first controls the cantilever 3 to rotate so that the person-umbrella release system switches to the water level, and then after a certain delay, controls the personnel release device 13 and the umbrella release device 12 to release simultaneously. Alternatively, the control system can first control the cantilever 3 to rotate so that the person-umbrella release system switches to the water level, and then after a certain delay, control the person release device 13 and the umbrella release device 12 to release in sequence after a certain delay. Alternatively, when the control system controls the cantilever 3 to rotate so that the person-umbrella release system smoothly switches to the water level, the personnel release device 13 and the umbrella release device 12 are released simultaneously. Alternatively, when the control system controls the cantilever 3 to rotate so that the person-umbrella release system smoothly switches to the water level, the control system controls the person release device 13 and the umbrella release device 12 to release sequentially with a certain delay.

[0039] The second type is the advanced drifting and falling water mode. In the drifting and falling water mode: When the control system controls the cantilever 3 to rotate rapidly at a set angular velocity, the person-umbrella release system quickly switches to the water level, and the person-umbrella release system reaches the set drift speed. At the same time, the control system controls the personnel release device 13 and the umbrella release device 12 to release simultaneously.

[0040] In actual training, trainees can only train in drifting water mode after they have achieved sufficient training volume in static water mode. The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
