[0023] As Figures 1-3 Indicated, this embodiment includes the launching barrel 1, the piston 2, the gas tank 3 and the inflation tank 4.
[0024] The launching barrel 1 is cylindrical, the launching barrel 1 is erected on the ground at a certain elevation angle, and the launching barrel 1 is used to launch unmanned plane.
[0025] The piston 2 is arranged in the launching barrel 1, the piston 2 is used to hold and boost unmanned plane, and the piston 2 can slide up and down in the launching barrel 1.
[0026] In this embodiment, the piston 2 is cylindrical, the arc surface of the piston 2 is provided with two rings of concave grooves 7b, each ring of concave grooves 7b is sleeved with a sealing ring 2a, and the sealing ring 2a specifically adopts rubber ring.
[0027] The two rubber rings can ensure the stability of the piston 2 sliding in the launching barrel 1, so that the piston 2 will not be tilted and stuck in the launching barrel 1 to cause safety hazards when the piston 2 is suddenly impacted by the gas pressure.
[0028] In other embodiments, the sealing ring 2a can also be provided with three or more rings.
[0029] In other embodiments, the gas storage tank 3 is used to store pressure gas, and in the present embodiment, high-purity nitrogen is used, and in other embodiments, air can also be used.
[0030] In the present embodiment, the gas storage tank 3 is in communication with the tail end of the launching barrel 1, and a second valve is further arranged between the communication channels. When the second valve is opened, the high-pressure nitrogen in the gas storage tank 3 rushes into the tail end of the launching barrel 1 to impact the piston 2, so as to promote the piston 2 to push the unmanned aerial vehicle out of the launching barrel 1.
[0031] Specifically, the present embodiment is provided with a base 7, and a sealing cavity is arranged in the base 7. The tail end of the launching barrel 1 is in communication with the gas storage tank 3 through the sealing cavity, and the second valve is arranged at the communication position of the gas storage tank 3 and the sealing cavity. A fourth valve 8 is arranged on the base 7 and is in communication with the sealing cavity and the outside.
[0032] The fourth valve 8 has at least two functions. Firstly, it can be used to release the pressure of the gas storage tank 3. Secondly, when the unmanned aerial vehicle is loaded, the piston 2 slides from the opening end to the tail end of the launching barrel 1. Since the piston 2 and the launching barrel 1 have good sealing effect, the space from the piston 2 to the tail end of the launching barrel 1 is continuously compressed. The fourth valve 8 can limit the flow of gas when the compression space is compressed, so that the piston 2 can slowly slide to the tail end of the launching barrel 1 at a relatively stable speed.
[0033] In other embodiments, a first valve can be directly arranged at the tail end of the launching barrel 1 to achieve the second function of the fourth valve 8 in the present embodiment.
[0034] The present embodiment further provides a boss 7a on the base 7, which corresponds to the shape of the tail end of the launching barrel 1. The tail end of the launching barrel 1 is sleeved and fixedly sealed on the boss 7a.
[0035] The boss 7a corresponds to the shape of the piston 2 and is provided with a reverse conical groove 7b, which is in communication with the sealing cavity. When the piston 2 falls into the tail end of the launching barrel 1, it is attached to the groove 7b. The groove 7b can improve the explosive force when the gas pressure is released, improve the impact effect, and make the stress surface of the piston 2 more extensive and uniform.
[0036] The gas tank 4 is in communication with the gas storage tank 3, and a third valve is further arranged at the communication position. The third valve is provided with a pressure gauge, so that the pressure of the gas filled into the gas storage tank 3 can be known when the gas tank 4 is filled with gas.
[0037] The gas storage tank 3 is arranged beside the launching tube 1, and the gas charging tank 4 is arranged at a far position, so the pipeline 5 is arranged, one end of the pipeline 5 is communicated with the gas storage tank 3, and the other end of the pipeline 5 is communicated with the gas charging tank 4. In this way, the gas storage tank 3 can be kept at a far distance when being charged.
[0038] Further, the embodiment further comprises a control button 6 connected with the second valve, and remote operation can be realized through the control button 6.
[0039] It should be noted that the up, down, left, right, front, back, top and tail directions described in the present application are all referred to the drawings, and are only used to more clearly express the technical solutions, and do not limit the protection scope.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the protection scope of the present application.
