Description

Technical Field

[0001] This invention belongs to the field of helicopter delivery technology, and specifically relates to a delivery device for an internally mounted airdrop vehicle and a helicopter. Background Technology

[0002] Many underwater self-propelled vehicles, buoys, and other equipment need to be deployed at sea via helicopters. Since each type of equipment has its own deployment conditions and methods, there are also many limitations on deploying items from inside a helicopter, such as the size and weight restrictions imposed by the internal space, and whether the deployed items, if equipped with parachutes, will snag on the exposed parts of the helicopter after deployment. Therefore, it is necessary to develop specialized deployment devices for certain types of equipment.

[0003] Therefore, a helicopter-mounted airdrop device that can repeatedly load and drop cylindrical equipment such as underwater self-propelled vehicles, buoys, and radio beacons inside helicopters, and can also be easily modified to meet the requirements for dropping other types of equipment, has become an urgent technical problem to be solved. Summary of the Invention

[0004] This invention provides a device for launching helicopter-mounted airdropped autonomous vehicles.

[0005] This invention provides a helicopter.

[0006] In view of this, the first aspect of the present invention provides a helicopter internal airdrop self-propelled vehicle delivery device for use in a helicopter, the helicopter including: a bulkhead, the delivery device including: a floor plate connected to the bulkhead; a delivery tube slidably connected to the floor plate, the delivery tube being slidable between a first position and a second position; and a stop block disposed on the floor plate, the stop block being able to fix the delivery tube in the first position.

[0007] Furthermore, the launch device for the helicopter internal air-dropped autonomous vehicle also includes: a vibration damping plate, which is installed at one end of the launch tube; when the launch tube is in the first position, the vibration damping plate is in contact with the inner wall of the launch tube, and one end of the launch tube is in contact with the bottom plate; when the launch tube is in the second position, the vibration damping plate can be removed from one end of the launch tube.

[0008] Furthermore, the launch device for the helicopter-mounted airdrop autonomous vehicle also includes a cover plate, located at the other end of the launch tube, for sealing the other end of the launch tube.

[0009] Furthermore, the launch device for the helicopter-mounted airdrop autonomous vehicle also includes a cover opening assembly, which is installed on the launch tube and used to control the opening of the cover.

[0010] Furthermore, the lid opening assembly includes: a lid opening component, disposed at the other end of the dispensing cylinder and connected to the lid plate, for controlling the opening of the lid plate; and a handle, disposed at one end of the dispensing cylinder and connected to the lid opening component, for controlling the lid opening component.

[0011] Furthermore, the cover opening assembly also includes a connecting rod, one end of which is connected to the cover opening component, and the other end of which is connected to the handle, for transmitting the force of the handle to the cover opening component.

[0012] Furthermore, the launch device for the helicopter-mounted airdrop autonomous vehicle also includes a torsion spring, located at the other end of the launch tube, used to control the closing of the cover.

[0013] Furthermore, the launch device for the helicopter internal airdropped autonomous vehicle also includes a fixing clip, which is installed on the base plate and used to fix the base plate to the bulkhead.

[0014] Furthermore, the launch device for the helicopter internal air-dropped autonomous vehicle also includes a stop structure, which contacts the stop block when the launch tube is in the first position.

[0015] According to a second aspect of the present invention, a helicopter is provided, including a helicopter internal airdrop autonomous vehicle deployment device according to the first aspect.

[0016] The beneficial effects of this invention are as follows: A base plate adapted to the internal interface of a helicopter can be added to a mature buoy delivery tube. A vibration damping plate is installed on the upper part, and a liftable and locking stop structure is designed in the middle. A manually operated opening assembly and cover plate are designed at the bottom. After the helicopter's lower cabin is opened, the delivery tube can be lowered to the limit position with the base plate before delivery, preventing the autopilot's tail parachute from opening and accidentally touching or snagging on the helicopter's exposed parts. The vibration damping plate can be removed for multiple reloading. After the autopilot is delivered, the delivery tube is raised, and the intermediate stop structure and the base plate block work together to secure the delivery tube tightly to the base plate, meeting the requirement of closing the lower cabin during normal helicopter flight. This device only requires modification of the helicopter's base plate and delivery tube to fit various helicopter cabins. Depending on the delivery conditions, it is suitable for hovering delivery and level flight delivery at a certain speed to deliver the autopilot or other equipment and materials. It can be applied to various helicopter deployment conditions and can meet the general needs of repeatedly loading and deploying cylindrical materials and equipment such as underwater self-propelled vehicles, buoys, and radio beacons inside helicopters.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] This invention proposes a helicopter internal air-drop vehicle deployment device for use in helicopters, the helicopter including: bulkheads, such as... Figure 1 As shown, the helicopter internal airdrop autonomous vehicle deployment device includes: a base plate 2, connected to the bulkhead; a deployment tube 5, slidably connected to the base plate 2, which can slide between a first position and a second position; and a stop block 8, which is disposed on the base plate 2 and can fix the deployment tube 5 in the first position.

[0023] In this embodiment, the base plate 2 is fixed to the bulkhead, and the delivery cylinder 5 is slidably connected to the base plate 2. Preferably, the delivery cylinder 5 is positioned at the center of the base plate 2, allowing it to slide on the base plate 2. In actual use, the delivery cylinder 5 has a first position and a second position relative to the base plate 2, where the first position is the delivery position and the second position is the filling position. A stop block 8 is provided on the base plate 2 to restrict the delivery cylinder 5 to the first position, i.e., the delivery position, thereby preventing the delivery cylinder 5 from detaching from the helicopter.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, the helicopter internal air-drop self-propelled vehicle delivery device also includes: a vibration damping plate 1, which is installed at one end of the delivery cylinder 5; when the delivery cylinder 5 is in the first position, the vibration damping plate 1 is in contact with the inner wall of the delivery cylinder 5, and the upper end of the delivery cylinder 5 is in contact with the bottom plate 2; when the delivery cylinder 5 is in the second position, the vibration damping plate 1 can be removed from one end of the delivery cylinder 5.

[0025] In this embodiment, a vibration damping plate 1 is also provided, located at one end of the delivery cylinder 5. Since the helicopter is in a swaying state during flight, therefore... Figure 2 As shown, when the delivery tube 5 is in the first position, one end of the delivery tube 5 will contact the base plate 2, thereby preventing the angle of the delivery tube 5 from changing due to the shaking of the helicopter and improving the accuracy of delivery. Meanwhile, as... Figure 3 As shown, when the dispensing cylinder 5 is in the second position, the anti-vibration pressure plate 1 can be removed from the dispensing cylinder 5, and the user can refill the dispensing material from the anti-vibration pressure plate 1.

[0026] Furthermore, the launch device for the helicopter-mounted airdrop autonomous vehicle also includes a cover plate 6, which is located at the other end of the launch tube 5 to seal the other end of the launch tube 5.

[0027] In this embodiment, a cover plate 6 is also provided. The cover plate 6 is located on the other end of the dispensing cylinder 5 and can close the other end of the dispensing cylinder 5, thereby preventing the dispensing of materials from happening automatically.

[0028] Furthermore, the launch device for the helicopter-mounted airdrop autonomous vehicle also includes: a cover opening assembly 4, which is installed on the launch tube 5 and is used to control the opening of the cover 6.

[0029] In this embodiment, a cover opening component 4 is also provided, which is installed on the dispensing cylinder 5 and can control the cover 6 to open. The user can control the cover 6 to open through the cover opening component 4, thereby realizing the dispensing of the dispensing material.

[0030] Furthermore, the opening assembly 4 includes: an opening member 41, which is disposed at the other end of the dispensing cylinder 5 and connected to the cover plate 6, for controlling the opening of the cover plate 6; and a handle 42, which is disposed at one end of the dispensing cylinder 5 and connected to the opening member 41, for controlling the opening member 41.

[0031] In this embodiment, the lid opening assembly 4 includes a lid opening component 41 and a handle 42. The lid opening component 41 is connected to the cover plate 6 and can control the opening of the cover plate 6. The handle 42 and the lid opening component 41 are respectively located at both ends of the dispensing cylinder 5. The user can control the operation of the lid opening component 41 through the handle 42. Since the handle 42 and the lid opening component 41 are respectively located at both ends of the dispensing cylinder 5, the user can control the dispensing from the other end of the cover, reducing the danger during dispensing.

[0032] Furthermore, the cover opening assembly 4 also includes a connecting rod 43, one end of which is connected to the cover opening member 41, and the other end of which is connected to the handle 42, for transmitting the force of the handle 42 to the cover opening member 41.

[0033] Furthermore, the helicopter internal airdrop autonomous vehicle deployment device also includes a torsion spring (not shown in the figure), located at the other end of the deployment tube 5, for controlling the closing of the cover plate 6.

[0034] In this embodiment, a torsion spring is also provided, connected to the cover plate 6, which can control the cover plate 6 to close automatically. When the user controls the cover plate 6 to open via the handle 42, the dispensing material is dispensed. Due to the action of the torsion spring, the cover plate 6 closes automatically immediately after the dispensing material is dispensed. Before refilling the dispensing cylinder 5, the handle 42 needs to be turned back to ensure that the cover plate 6 can catch the newly added dispensing material.

[0035] Furthermore, the launch device for the helicopter internal air-dropped autonomous vehicle also includes: a fixing clip 3, which is set on the base plate 2 and used to fix the base plate 2 to the bulkhead.

[0036] Furthermore, the helicopter internal air-dropping autonomous vehicle deployment device also includes a stop structure 7, which contacts the stop block 8 when the deployment tube 5 is in the first position.

[0037] According to a second aspect of the present invention, a helicopter is provided, including a helicopter internal airdrop autonomous vehicle deployment device according to the first aspect.

[0038] The bottom plate 2 of the helicopter's internal cabin is replaced and secured to the helicopter cabin wall by fixing clips 3. A certain type of release tube is placed in the middle, with an anti-vibration pressure plate 1 installed on top and a cover plate 6 installed below, which is fixed to the protruding edge on the bottom plate 2. When the release command is given, the operator can open the cover plate 6 by rotating the handle on the cover opening assembly 4. The autonomous vehicle or other equipment to be released in the release tube 5 can be directly released into the water due to its own weight. In this way, it is possible to avoid the released equipment, autonomous vehicle, and other equipment with drag chute attached to the tail end snagging on exposed objects inside or outside the helicopter.

[0039] After the autonomous vehicle is released, the torsion springs designed on the outer edge of the cover plate 6 and the release tube 5 automatically spring back the cover plate 6, covering the lower end of the release tube 5. Rotating the release handle on the upper part of the cover opening assembly 4 in the opposite direction can lock the cover plate 6. Unscrewing the anti-vibration pressure plate 1 on the upper part of the release tube allows for the loading of the next autonomous vehicle. After the release is completed, the release tube is lifted, and the stop structure 7 on the release tube and the stop block 8 designed on the bottom plate 2 are used to lock the release tube 5 onto the bottom plate 2. The helicopter's lower cabin can then be closed, and the helicopter can enter normal flight mode.

[0040] This device boasts high repeatability, simple operation, and high reliability. It does not occupy internal helicopter space, greatly maximizing the utilization of the limited space inside the helicopter. It is highly original.

[0041] Furthermore, a certain type of domestically developed underwater self-propelled vehicle is suitable for various deployment platforms and is equipped with a buoy deployment tube for a certain type of fixed-wing aircraft. In order to simplify the design and reduce the development cost, this patent modifies the buoy deployment tube by modifying and adding structural components that can be adapted to the internal cabin of a helicopter, so that the self-propelled vehicle can be attached to the helicopter and safely deployed when the helicopter is hovering or in low-speed flight, while also meeting the requirements for normal helicopter flight.

[0042] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
