[0021] Need to explain, the utility model discloses unmanned aerial vehicle airborne net gun electric control firing system, when installing, the mounting plate 6 is connected with the aircraft, and the mounting plate 6 is connected between the mounting outer frame 1 and adopts specially designed shock-absorbing ball 61, these shock-absorbing balls 61 can effectively absorb the impact force from the net gun launch, thereby reducing the influence on the equipment. This design not only improves the stability of the equipment, but also enhances its impact resistance, so that the equipment can still maintain good working condition in harsh environment. Therefore, this advanced design scheme brings significant improvement to the performance and reliability of the equipment, a hollow net gun head 5 is arranged behind the long launch tube 51, each long launch tube 51 is connected with the net gun head 5 at an angle of 15 degrees, this design can make the 3m*3m net used fully expand at a distance of about 6m, meet the use in the environment of diversity, add rubber ring around the net bomb, can exert the outward tension on the net bomb at the moment of launching, help the net bomb expand faster and more evenly, this even expansion is very critical to ensure that the net covers the target area, especially when capturing the moving target, the bottom has a silica gel plug, when shooting, the high-pressure gas behind the net bomb will push the bottom plug forward, so that the internal gas pressure accumulates, which can effectively increase the launch distance of the net gun, the front connecting shaft of the electromagnetic valve 4 is connected with the net gun head 5, and the rear connecting shaft is connected with the pressure relief device 32, the electromagnetic valve 4 is used as the control mode of the firing mechanism, compared with the traditional mechanical steering engine control mode, the electromagnetic valve 4 can realize more rapid firing response, improve the response speed and accuracy of the firing mechanism. The electromagnetic valve 4 is characterized by fast response speed, which can complete the firing action in a very short time, ensuring that the firing mechanism can react to external signals in real time, thereby improving the response capability and reliability of the device. The principle is as follows: when energized, the electromagnetic force opens the pilot valve 46 in the pilot hole, the pressure in the upper chamber 44 drops rapidly, forming a low-high pressure difference around the closing member, the fluid pressure pushes the main valve 45 upwards, and the valve is opened; when de-energized, the spring force of the pilot valve 46 closes the pilot hole, and the inlet pressure rapidly enters the lower chamber 43 through the bypass hole, forming a low-high pressure difference around the main valve 45, the fluid pressure pushes the main valve 45 downwards, and the valve is closed, wherein the design of the electromagnetic valve 4 adopts a PWM controller.
