Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) launching, and in particular to a multi-burst tube-fired UAV launching system. Background Art

[0002] Most of the current canister-launched drone launch systems use a single launch canister with a single gas cylinder, which is inflated using an air pump. However, the inflation is troublesome and the launch preparation time is long, which cannot meet the use scenarios of multiple batches of continuous launches. The simple single-canister structure requires inflation and loading of the aircraft after each launch, which requires a long preparation time and is difficult to meet the needs of multiple batches of rapid and continuous launches. Its structure is simple, the use preparation time is long, and it can only simply meet the launch mission of a single sortie. Summary of the invention

[0003] In view of this, the present invention provides a multi-shot tube-fired UAV launching system, which can realize continuous and rapid launching of multiple UAVs.

[0004] The present invention is achieved through the following technical scheme: a multi-shot tube-launched unmanned aerial vehicle launching system, including a plurality of launching tubes and corresponding launching switches, air pipes, launching gas cylinders, valves and high-pressure gas cylinders; the plurality of launching tubes are connected to the same launching gas cylinder through corresponding air pipes, the air pipe is provided with a launching switch corresponding to the launching tube, and the opening and closing of the launching switch correspond to whether the launching tube is connected to the launching gas cylinder; the launching gas cylinder is connected to the high-pressure gas cylinder through a valve, and the valve can be automatically opened when the launching gas cylinder is emptied, and is used to decompress the gas in the high-pressure gas cylinder and inflate the launching gas cylinder; when the launching gas cylinder is full of gas, the valve can be automatically closed.

[0005] Furthermore, the valve is a pressure reducing valve provided with a pressure sensor and a control system. The pressure sensor monitors the pressure of the transmitting gas cylinder and converts it into an electrical signal and sends it to the control system. The control system receives and processes the electrical signal and controls the opening and closing of the pressure reducing valve.

[0006] Furthermore, the launch switch is a solenoid valve, and the solenoid valve is automatically closed after the launch tube is launched.

[0007] Furthermore, it also includes a launching module, a plurality of launching tubes and corresponding solenoid valves are arranged in the launching module, a power switch of the solenoid valve is arranged on the outer surface of the launching module, and the air pipe extends out of the launching module and is connected to the launching gas cylinder.

[0008] Furthermore, the high-pressure gas cylinder is a pre-filled high-pressure gas cylinder with a built-in gas pressure of 30MP.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The multiple launch tubes of the present invention are provided with respective corresponding launch switches and are connected to the same launch gas cylinder. The high-pressure gas cylinder automatically inflates the launch gas cylinder that exhausts the gas by reducing the pressure through the pressure reducing valve. The drones can be launched continuously and quickly in batches. In addition, the system is light in weight and the launch tube itself is short in length, which is convenient for reducing the weight of the upper part of the launch system.

[0011] 2. The present invention monitors the pressure in the launch gas cylinder through a pressure sensor, automatically opens the pressure reducing valve to inflate when the launch gas cylinder is emptied, and automatically closes the pressure reducing valve when the launch gas cylinder is full, thereby realizing rapid inflation by utilizing the high and low pressure inflation principle.

[0012] 3. The launch switch of the present invention uses an electromagnetic valve. Pressing the electromagnetic valve switch connects the launch cylinder to the corresponding launch tube. After the UAV is launched, the electronic valve can be automatically closed. At this time, the launch cylinder is not connected to the launch tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention provides a multi-shot tube-fired UAV launch system, such as Figure 1 As shown, the system includes a plurality of launch tubes 1 and corresponding launch switches, air pipes, launch gas cylinders 2, valves and high-pressure gas cylinders 3; the plurality of launch tubes 1 are connected through corresponding air pipes, each air pipe is provided with a launch switch corresponding to the launch tube 1, and all air pipes are finally connected together and connected to the launch gas cylinder 2, and the opening and closing of the launch switch corresponds to whether the launch tube 1 is connected to the launch gas cylinder 2; the launch gas cylinder 2 is connected to the high-pressure gas cylinder 3 through the valve, and the valve can be automatically opened when the launch gas cylinder 2 is emptied, so as to inflate the launch gas cylinder 2 after decompressing the gas in the high-pressure gas cylinder; when the launch gas cylinder is full of gas, the valve can be automatically closed.

[0017] In this embodiment, the launch switch is a solenoid valve, and the solenoid valve automatically closes after the launch tube 1 is launched. The valve is a pressure reducing valve 4 equipped with a pressure sensor and a control system. The pressure sensor is used to monitor the gas pressure in the launch cylinder 2, convert it into an electrical signal and send it to the control system; the control system receives and processes the electrical signal, and controls the opening and closing of the pressure reducing valve 4. The corresponding solenoid valve of the launch tube 1 is opened, and the launch tube 1 launches the drone. After launching a drone in the launch tube 1, the gas in the launch cylinder 2 is emptied, and the pressure sensor detects that the pressure in the launch cylinder 2 is reduced, and the pressure reducing valve 4 is automatically opened. The high-pressure gas cylinder 3 automatically inflates the launch cylinder 2, and the launch of the next launch tube 1 can continue, so that a single launch cylinder 2 is used, and the high-pressure gas cylinder 3 is used to automatically replenish compressed air for multiple launch cylinders 2 through the pressure reducing valve 4.

[0019] Specifically, the high-pressure gas cylinder 3 is a pre-filled high-pressure gas cylinder with a built-in gas pressure of 30MP. Compared with the slow and inefficient air pump, the pre-filled high-pressure gas cylinder 3 is easy to replace and can be quickly refilled. In order to simplify the weight of the system, the pressure reducing valve 4 is used to reduce the 30MP high pressure of the high-pressure gas cylinder 3. The pressure sensor sends an electrical signal to the control system to control the pressure reducing valve 4 to inflate the launch gas cylinder 2. The high-pressure gas cylinder 3 can be quickly replaced after it is consumed, which can ensure the long-term operation of the system.

[0021] The present invention provides a convenient launching system for the continuous launching of tube-launched UAVs. In some usage scenarios requiring a UAV cluster, the UAVs can be launched quickly. Moreover, the system has low weight, high launching speed, short launching preparation time, convenient use, high degree of automation, and low requirements on operators.
