[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Figure 1 One embodiment of the present invention provides a launching device for a patrol UAV for launching on the water surface, comprising:

[0030] The duckweed device 10 is used to make the whole device float on the water surface.

[0031] The launch tube 20 is arranged on the duckweed device 10, and a launch channel 21 is formed inside the launch tube 21. The launch channel 21 is provided with a launch port 211, a gas generator 23, a piston 22 and an exhaust pipe 24. The launch port 211 is located at the top of the launch tube 20, and the gas generator 23 and the piston 22 are arranged in sequence at the bottom of the launch tube 20. The exhaust pipe 24 extends along the launch direction of the launch channel 21. The air inlet of the exhaust pipe 24 is connected to the launch channel 21, and the air outlet of the exhaust pipe 24 is connected to the outside of the launch channel 21. The duckweed device 10 allows the launch tube 20 to maintain a predetermined angle relative to the water surface. In this embodiment, the launch tube 20 maintains a vertical upward angle, and the duckweed device 10 is conducive to maintaining the launch angle of the launch tube 20 during launch.

[0032] The signal receiving system 30 is arranged on the duckweed device 10 and is connected to the gas generator 23 by signal. The signal receiving system 30 can receive wireless signals. For example, the signal receiving system 30 can receive signals through satellite communication. The signal receiving system 30 has a built-in battery to ensure that the signal receiving system 30 can be in standby mode for a long time.

[0033] The patrol drone 40 is disposed in the launch tube 20 and is configured to be launched along the launch channel 21 under the push of the piston 22. The structure of the patrol drone 40 can be designed according to actual needs. For example, in this embodiment, the patrol drone 40 is a foldable wing type. When on standby, it is deployed in the launch channel 21 of the launch tube 20 in a folded state. After launch, the wings are unfolded to enter the flight mode and perform a predetermined flight mission.

[0034] During the launch, the high-pressure gas generated by the gas generator 23 drives the piston 22 to move, and the piston 22 pushes the patrol drone 40 to move along the launch channel 21, and then ejects the launch tube 20; during the launch, the exhaust pipe 24 can discharge part of the gas generated by the gas generator 23, which is beneficial for the exhaust pipe 24 to reduce the air pressure in the launch channel 21, and avoid the excessively high-pressure airflow to generate strong turbulence, which affects the attitude stability of the entire device. In this embodiment, the air inlet of the exhaust pipe 24 maintains a predetermined distance from the piston 22. Before the high pressure drives the piston 22 through the air inlet, the high pressure can provide sufficient acceleration for the piston 22, so that the piston 22 has sufficient kinetic energy to drive the patrol drone 40 to eject, and after the piston 22 passes through the air inlet, the exhaust pipe 24 gradually reduces the air pressure in the launch channel 21, and avoids the excessively high pressure airflow after the piston 22 leaves the launch channel 21. Disturb the launch port 211 and affect the launch attitude of the launched patrol drone 40, and at the same time offsets part of the reaction force generated when the patrol drone 40 is launched, and maintains the attitude stability of the launch device.

[0035] The duckweed device 10 and the launching tube 20 are made of waterproof and corrosion-resistant materials, which are conducive to being immersed in water for a long time, thereby effectively maintaining the stable state of the patrol drone 40 in the launching tube 20.

[0036] In some optional embodiments, the launch port 211 is provided with an end cover 25, the end cover 25 closes the launch port 211, and the end cover 25 is snap-fitted with the launch tube 20, and is configured to be detached from the launch port 211 under the push of the patrol drone 40. The end cover 25 is used to protect the patrol drone 40 in the launch tube 20 from environmental erosion such as rain and exposure. During launch, the piston 22 pushes the patrol drone 40 to hit the end cover 25, so that the end cover 25 breaks or detaches from the launch port 211, thereby opening the launch port 211. In this embodiment, the end cover 25 is made of fragile material, so that the patrol drone 40 can open the launch port 211 by smashing the end cover 25. This design is conducive to reducing the influence of the end cover 25 on the launch angle of the patrol drone 40, and facilitates the patrol drone 40 to be smoothly ejected from the launch tube 20.

[0037] In some optional embodiments, the horizontal cross section of the duckweed device 10 gradually increases from bottom to top, so the buoyancy of the duckweed device 10 increases with each unit of draft depth. Since the structure volume of the duckweed device 10 near the lower part is small, before launching, the duckweed device 10 can be made to draft deeper, which is conducive to lowering the center of gravity of the entire device, so that the center of gravity of the entire device is located below the horizontal plane, which is conducive to maintaining the posture of the duckweed device 10 during launch, and then maintaining the posture of the launch tube 20. In addition, when launching the patrol drone 40, the duckweed device 10 sinks due to the reaction force. Since the structure volume of the duckweed device 10 near the upper part is large, the buoyancy of the duckweed device 10 due to sinking is greatly increased, so it can effectively offset part of the reaction force when the patrol drone 40 is launched, thereby effectively improving the posture stability of the duckweed device 10 and the launch tube 20 during launch. In this embodiment, the duckweed device 10 is in the shape of an inverted truncated cone. Of course, the duckweed device 10 can also adopt other shapes suitable for practical use, not limited to this example.

[0038] In some optional embodiments, a portion of the launch tube 20 is located below the duckweed device 10, which is conducive to lowering the center of gravity of the entire device, and another portion of the launch tube 20 is located above the duckweed device 10, which is conducive to maintaining the balance of the entire device and increasing the height of the launch port 211 so that the launch port 211 is not easily exposed to water, which is conducive to protecting the patrolling drone in the launch channel 21.

[0039] In some optional embodiments, an installation channel 11 is provided on the duckweed device 10, and the launching tube 20 is inserted into the installation channel 11. The launching tube 20 is fixed to the duckweed device 10 by a fixing ring 12, thereby facilitating the production, assembly and transportation of the duckweed device 10 and the launching tube 20.

[0040] In some optional embodiments, the launch tube 20 includes an upper tube 26 and a lower tube 27, and the upper tube 26 and the lower tube 27 are detachably connected by a threaded structure. The upper tube 26 and the lower tube 27 together form a launch channel 21, and the upper tube 26 is fixed on the duckweed device 10. Due to the detachable design of the lower tube 27, it is convenient to store, replace, and replenish the patrol drone 40. In this embodiment, the upper tube 26 and the lower tube 27 are threadedly matched. Of course, the upper tube 26 and the lower tube 27 can also be detachably matched by a buckle structure, a latch structure, or a snap-on structure, etc., without limiting this example. In this embodiment, the launch port 211 is formed on the upper tube 26, and the exhaust pipe 24 is arranged on the upper tube 26.

[0041] In some optional embodiments, the launching channel 21 is provided with a plurality of exhaust pipes 24, and the plurality of exhaust pipes 24 are evenly arranged around the launching channel 21, so as to be conducive to evenly discharging high-pressure gas, making the air pressure in the launching channel 21 more uniform, and making the force on the piston 22 more balanced.

[0042] In some optional embodiments, the exhaust pipe 24 extends from the side of the launch tube 20 to the outside of the launch tube 20, the air inlet of the exhaust pipe 24 is close to the inner wall of the launch channel 21 and maintains a predetermined distance from the piston 22, and the air outlet of the exhaust pipe 24 is facing away from the launch tube 20. The gas exhausted from the exhaust pipe 24 is discharged away from the launch tube 20, thereby preventing the gas exhausted from the exhaust pipe 24 from affecting the launch of the cruising drone 40.

[0043] In some optional embodiments, a one-way valve 28 is provided in the exhaust pipe 24, and the one-way valve 28 limits the airflow from the exhaust outlet of the exhaust pipe 24 to the air inlet of the exhaust pipe 24, thereby preventing the outside air from entering the launch tube 20 through the exhaust pipe 24, thereby avoiding the outside air from affecting the stability of the airflow inside the launch channel 21, making the movement of the piston 22 more stable, and also conducive to maintaining the posture balance of the duckweed device 10 and the launch tube 20 relative to the water surface.

[0044] In some optional embodiments, the piston 22 is interference fit with the launching channel 21 , thereby improving the sealing performance and preventing the high-pressure gas from leaking from the gap between the launching channel 21 and the piston 22 .

[0045] 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.
