Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to an autonomous launching device of a UAV for a ship. Background Art

[0002] Since my country's territorial waters are large, a large number of military ships need to be patrolled. Since the inspection range on military ships is small, it is necessary to use drones to conduct flight surveillance over the territorial waters to increase the range of military ship surveillance.

[0003] In the existing technology, drones on military ships usually land in drone storage bins, and horizontal correction of drones during takeoff and launch is an important step to ensure flight stability and reliable performance. However, when military ships are sailing at sea, turbulence is inevitable, which will affect the horizontal correction of the drone before launch, resulting in incorrect posture of the drone during takeoff. Moreover, when sailing in the ocean, there is a lot of water vapor in the air, and traditional storage bins cannot quickly seal the openings, causing water vapor to enter the storage bin and affect the drone's circuit. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when a ship is sailing on the sea, it is inevitable that there will be bumps, which will affect the horizontal correction of the UAV before launching, resulting in incorrect posture of the UAV during takeoff and water vapor easily affecting the UAV circuit. A self-driving UAV launch device for ships is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for autonomously launching drones for ships comprises a storage box with an opening at the top, and also comprises: a transverse ring plate that is lifted and connected to the storage box, wherein the transverse ring plate is rotatably connected to a longitudinal ring plate, a disc is slidably connected to the longitudinal ring plate, the bottom of the disc is rotatably connected to a balance plate, and the top of the disc is fixedly connected to a placement plate; a protective cover that is slidably connected to the open end of the storage box, and when the transverse ring plate rises or falls in the cavity of the storage box, the protective cover can unseal or block the open end of the storage box.

[0007] In order to enable the longitudinal ring plate to rotate left and right, preferably, a rotating shaft is fixedly connected to the longitudinal ring plate, and the rotating shaft is rotatably connected to the inner wall of the transverse ring plate.

[0008] In order to enable the disc to slide on the longitudinal ring plate, a slide plate is fixedly connected to the disc, a sliding groove is provided on the longitudinal ring plate, and the slide plate is slidably connected in the sliding groove.

[0009] In order to adjust the level of the disc, further, a motor is fixedly connected to the bottom of the disc, and the balance board is fixedly connected to the output end of the motor.

[0010] In order to facilitate the lifting and moving of the transverse ring plate, preferably, a mounting box is fixedly connected to the inner wall of the storage box, a screw rod is rotatably connected inside the mounting box, a movable block is threadedly connected to the screw rod, and the transverse ring plate is fixedly connected to the movable block.

[0011] In order to facilitate the movement of the protective cover, preferably, a booster cylinder is fixedly connected to the storage box, a booster rod is slidably connected to the booster cylinder, a piston is provided at one end of the booster rod, and the piston is in contact with the inner wall of the booster cylinder, and the other end of the booster rod is fixedly connected to the transverse ring plate, a guide cylinder is fixedly connected to the storage box, a guide rod is slidably connected to the guide cylinder, a piston is provided at one end of the guide rod, and the piston is in contact with the inner wall of the guide cylinder, and the other end of the guide rod is fixedly connected to the protective cover through a connecting plate, and the booster cylinder and the guide cylinder are connected through a pipe.

[0012] Compared with the existing technology, the present invention provides an autonomous launch device for a naval vessel drone, which has the following beneficial effects:

[0013] 1. The ship's drone autonomous launch device automatically levels the drone through a disc, allowing it to be in a relatively horizontal state during takeoff and launch. This facilitates subsequent horizontal correction of the drone, ensuring stable flight and reliable performance, and preventing turbulence on the sea surface from affecting the horizontal correction of the drone before launch, preventing the drone from taking off in an incorrect posture.

[0014] 2. The ship's drone autonomous launch device can open or close in real time following the placement plate by utilizing a protective cover, reducing the time it takes for water vapor to enter the storage box. It can quickly and synchronously seal or open the opening to prevent the interior of the storage box from being exposed to the air, reduce the amount of water vapor entering the storage box, and prevent it from affecting the drone's circuit.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can enable the drone to be launched in a relatively horizontal state during takeoff, which is convenient for subsequent horizontal correction of the drone, prevents the turbulence on the sea surface from affecting the horizontal correction of the drone before launch, and prevents the drone from taking off with an incorrect posture.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Therefore, they cannot be understood as limitations on the present invention.

[0023] Example:

[0024] Reference Figures 1-4 A ship-use drone autonomous launch device includes a storage box 1 with an opening at the top, and also includes: a transverse ring plate 2 that is lifted and connected to the storage box 1, wherein a longitudinal ring plate 3 is rotatably connected to the transverse ring plate 2, a disc 4 is slidably connected to the longitudinal ring plate 3, a balance plate 6 is rotatably connected to the bottom of the disc 4, and a placement plate 13 is fixedly connected to the top of the disc 4; a protective cover 7 is slidably connected to the open end of the storage box 1, and when the transverse ring plate 2 rises or falls in the cavity of the storage box 1, the protective cover 7 can unseal or block the open end of the storage box 1.

[0025] A drone can be placed on the placement plate 13. When the drone needs to be launched, the transverse ring plate 2 can be controlled to rise. During the rising process, the disc 4 will maintain a relatively horizontal state on the longitudinal ring plate 3 under the force of the rotation of the bottom balance plate 6, and the longitudinal ring plate 3 can also rotate left and right on the transverse ring plate 2. When the storage box 1 is in a bumpy state, the longitudinal ring plate 3 and the transverse ring plate 2 cooperate with each other and, under the rotation of the balance plate 6, will drive the disc 4 to automatically level, so that the drone can be launched in a relatively horizontal state during takeoff, which is convenient for subsequent horizontal correction of the drone, ensuring the stability of the drone's flight and reliable performance, preventing the bumps on the sea surface from affecting the horizontal correction of the drone before launch, and preventing the drone from taking off with an incorrect posture.

[0026] When the transverse ring plate 2 rises, it can drive the longitudinal ring plate 3 to rise synchronously. The disc 4 on the longitudinal ring plate 3 will drive the drone on the placement plate 13 to move upward, and move the drone to the top of the storage box 1. During this process, the protective cover 7 on the open end of the storage box 1 will automatically open to both sides, thereby making the open end of the storage box 1 in an open state, so that the drone can be launched autonomously and fly into the air.

[0027] Furthermore, a rotating shaft 12 is fixedly connected to the longitudinal ring plate 3 and rotatably connected to the inner wall of the transverse ring plate 2. A slide 11 is fixedly connected to the disc 4, and a slide 11 slides within a slot defined in the longitudinal ring plate 3. A motor 5 is fixedly connected to the bottom of the disc 4, and a balance plate 6 is fixedly connected to the output end of the motor 5.

[0028] When the motor 5 drives the balance board 6 to rotate, the balance board 6 will form a balancing force during rotation, and the disc 4 can adjust its own position with the cooperation of the longitudinal ring plate 3 and the transverse ring plate 2, so that the placement plate 13 on the top of the disc 4 is in a relatively horizontal state, making the calibration of the drone before launch smoother.

[0029] When the transverse ring plate 2 rises or falls in the cavity of the storage box 1, the protective cover 7 can unseal or seal the open end of the storage box 1. The principle is as follows: a mounting box 8 is fixedly connected to the inner wall of the storage box 1, a screw rod 9 is rotatably connected inside the mounting box 8, a movable block 10 is threadedly connected to the screw rod 9, the transverse ring plate 2 is fixedly connected to the movable block 10, and the device is provided with four groups of mounting boxes 8 which are symmetrically arranged inside the storage box 1.

[0030] The screw rod 9 can be driven by a motor. When the motor drives the screw rod 9 to rotate counterclockwise, the movable block 10 will drive the transverse ring plate 2 to move downward. When the motor drives the screw rod 9 to rotate clockwise, the movable block 10 will drive the transverse ring plate 2 to move upward, thereby causing the transverse ring plate 2 to rise or fall in the cavity of the storage box 1.

[0031] It needs to be explained that a booster cylinder 14 is fixedly connected in the storage box 1, a booster rod 15 is slidably connected to the booster cylinder 14, a piston is provided at one end of the booster rod 15, and the piston fits against the inner wall of the booster cylinder 14, the other end of the booster rod 15 is fixedly connected to the transverse ring plate 2, a guide cylinder 16 is fixedly connected to the storage box 1, a guide rod 17 is slidably connected to the guide cylinder 16, a piston is provided at one end of the guide rod 17, and the piston fits against the inner wall of the guide cylinder 16, the other end of the guide rod 17 is fixedly connected to the protective cover 7 through a connecting plate, and the booster cylinder 14 and the guide cylinder 16 are connected through a pipe.

[0032] When the motor drives the screw rod 9 to rotate clockwise, the movable block 10 will drive the transverse ring plate 2 to move upward. At this time, the booster rod 15 will move upward synchronously, and the piston on the booster rod 15 will move synchronously to compress the gas above the piston, so that the gas will be transported to the guide cylinder 16 through the pipeline, and then the piston will push the guide rod 17 toward the outside. The other end of the guide rod 17 is fixedly connected to the protective cover 7 through the connecting plate, which will push the protective cover 7 toward both sides, so that the two groups of protective covers 7 on the open end of the storage box 1 are separated.

[0033] When the motor drives the screw rod 9 to rotate counterclockwise, the movable block 10 will drive the transverse ring plate 2 to move downward. At this time, the booster rod 15 will move downward synchronously, and the piston on the booster rod 15 will move synchronously, and negative pressure will be generated above the piston. At this time, the gas in the guide cylinder 16 will be replenished to the inside of the booster cylinder 14 through the pipeline, and the other end of the guide rod 17 is fixedly connected to the protective cover 7 through the connecting plate, which will push and fit the two sets of protective covers 7 from both sides, so that the two sets of protective covers 7 on the open end of the storage box 1 are merged.

[0034] By utilizing the protective cover 7, the protective cover 7 can be opened or closed in real time following the placement plate 13, reducing the time for water vapor to enter the storage box 1. The opening can be quickly and synchronously sealed or opened to prevent the interior of the storage box 1 from being exposed to the air, reducing the amount of water vapor entering the storage box 1, and preventing it from affecting the circuit of the drone.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
