DETAILED DESCRIPTION

[0028] like Figure 1-9 As shown, the bullet continuous firing device of the UAV airborne platform includes a power system 1, which is used to store compressed air and realize remote control of the UAV by ground personnel; a pressure regulating system 2 connected to the power system 1, which is used to adjust the pressure of the high-pressure gas; a firing system 3 connected to the pressure regulating system 2, which is used to fire bullets; and a filling system 4 connected to the firing system 3, which is used to fill non-metallic bullets.

[0029] The power system 1 includes a gas cylinder 5 and a solenoid valve 6 connected to the gas cylinder 5; the pressure regulating system includes a pressure regulating device connected to the solenoid valve 6 and a cylinder device connected to the pressure regulating device; the launching system 3 includes a sliding shuttle tube 7 connected to the cylinder device, a first spring 8 sleeved on the sliding shuttle tube 7, and a barrel 9 and a chamber 10 connected to the sliding shuttle tube 7; the filling system 4 includes a magazine device connected to the chamber 10.

[0030] Specifically, one end of the gas cylinder 5 connected to the solenoid valve 6 is provided with a threaded interface 5-1, and a sealing film 5-2 is provided on the threaded interface 5-1; the inner end of the solenoid valve 6 connected to the threaded interface 5-1 is provided with a funnel-type puncture needle 6-1.

[0031] In this embodiment, under the requirements of high pressure and large capacity of compressed gas, the bearing capacity of the gas cylinder should also be guaranteed, so the strength of the gas cylinder should meet the minimum safety. Therefore, aluminum alloy is usually used as the material for manufacturing the gas cylinder 5, and high-pressure carbon dioxide gas is stored inside.

[0032] Among them, the threaded interface 5-1 adopts a standard interface, and the threaded connection at the gas cylinder 5 also belongs to the market standard. Therefore, the user can customize the size of the gas cylinder 5 according to the purpose of use; as long as it can be safely connected to the device, the gas cylinder of similar size can be purchased through any means for replacement operation. The purpose of doing so is to be able to directly purchase qualified gas cylinders from the market when in urgent need, saving the time and cost spent on design and manufacturing, providing convenience for the assembly of the complete product, and also conducive to efficient configuration and promotion.

[0033] The electromagnetic valve 6 is used as an intermediary device and is connected to the gas cylinder 5 by a threaded connection, which is simple and has high stability. The gas cylinder 5 has a sealing effect through a layer of film, so how to remove the seal must also be considered during assembly. To achieve this action, the device is designed with a funnel-shaped needle 6-1 installed inside the electromagnetic valve port. When the gas cylinder 5 is rotated into the gas cylinder 5 through the threaded connection, the tip of the funnel-shaped needle 6-1 will pierce the sealing film and remove the restriction.

[0034] In addition, the use of electromagnetic valve 6 control is an innovative move of the present device. Traditional firearms are manually triggered in the form of a trigger, which is indeed very convenient to operate, but it is only limited to land. If the combat scene is transferred to the air, this method will instantly fail. Therefore, the electromagnetic valve can be used to play the role of a trigger through remote control to control the firing and stopping of bullets.

[0035] As can be seen from the above, the working process of the power system 1 is as follows: since the gas cylinder 5 is sealed by the sealing film 5-2, when it is connected to the solenoid valve 6, the film is broken by the funnel-shaped puncture needle 6-1 in the solenoid valve 6, so that the high-pressure gas flows out. However, since the solenoid valve switch is in the closed state at this moment, the gas flow cannot flow forward.

[0036] When the launch device decides to fire a bullet, the operator turns on the electromagnetic switch, the coil generates a magnetic field to lift the armature, the airflow is turned on, and the high-pressure gas can flow to the next system.

[0037] Specifically, the pressure regulating device includes a rear end inlet 11 connected to the solenoid valve 6, and a pre-boost chamber 12 connected to the rear end inlet 11, an overpressure protection mechanism and a pressure regulating nut 13 are provided at the front end of the pre-boost chamber 12, and the pre-boost chamber 12 is connected to the overpressure protection mechanism and the pressure regulating nut 13 through an air channel 14; the cylinder device includes a pressure buffer chamber 15 connected to the pressure regulating nut 13, and a front end outlet 16 connected to the pressure buffer chamber 15.

[0038] The overpressure protection mechanism includes a tightening nut 17 , a second spring 18 is sleeved on the tightening nut 17 , and a small ball 19 is arranged above the second spring 18 .

[0039] In this embodiment, the size of the gas flow rate is controlled by screwing in the length of the pressure regulating nut 13, and the optimal length range for firing a bullet can be measured through experiments; the overpressure protection mechanism is a device that plays a role when the internal pressure of the pressure regulating system is too high. Under normal circumstances, the small ball 19 is pressed against the contacting channel by the elastic force of the second spring 18; when the internal pressure is too high, the strong air pressure will push the small ball 19 open and release part of the air pressure from the outlet. When the internal air pressure returns to the set value, the small ball 19 will be re-sealed by the elastic force of the second spring 18.

[0040] The high-pressure gas in the pre-boost chamber 12 enters from the rear inlet 11 and gradually fills the space, so it stays for a period of time. During the stay, the internal pressure gradually increases here, and the initial stage of pre-expansion and pressure boosting is implemented to convert the kinetic energy of the high-pressure gas into potential energy, ensuring that the energy of the high-pressure gas can be effectively utilized. The rear inlet 11 is the entrance for the high-pressure gas to enter the pressure regulating system.

[0041] The high-pressure gas in the pressure buffer chamber 15 after the first pre-pressurization flows into the pressure buffer chamber 15 for storage after the pressure regulation, and due to the emission effect, in addition to consuming the pressure in the space of the pressure buffer chamber 15, the pressure buffer chamber 15 will continue to maintain a high-pressure state. The front end outlet 16, through which the airflow of the pressure regulating system flows out, plays a conductive role.

[0042] From the above, it can be seen that the working process of the pressure regulating system 2 is as follows: the pressure regulating system is directly connected to the power system. After the high-pressure gas passes through the solenoid valve 6, it enters the pressure regulating system from the rear end inlet 11. The high-pressure gas is pre-expanded and boosted in the pre-boost chamber 12, and then flows forward after the pressure is increased. The pressure and flow rate are adjusted to a suitable level through the pressure regulating nut 13, and then it flows into the cylinder and is stored. After filling the entire space, it flows out from the front end outlet 16 and goes to the next system. During this period, if the internal pressure is too high, the overpressure protection device will start to work and reduce the internal pressure.

[0043] Specifically, the sliding shuttle tube 7 includes a tube body 20 and a sliding column 21 arranged in the tube body 20. The front end of the tube body 20 is provided with a pressure feed port 22, and the pressure feed port 22 is connected to the tube body 20 through an air hole 30. The rear end of the tube body 20 is provided with a circular ring 23, and the circular ring 23 is provided with a spring bayonet 24 for installing the first spring 8.

[0044] The inner wall of the tube body 20 cooperates with the outer wall surface of the front end outlet 16 of the cylinder device, and the length of the tube body 20 is greater than the length of the front end outlet 16 of the cylinder device.

[0045] In this embodiment, the device uses a spherical bullet with a diameter of 10 mm. The pressure feed port 22 has a diameter smaller than the diameter of the bullet, so it can play a role in blocking the bullet. On the other hand, when the compressed gas comes from the back, it will flow through this port, thereby pushing the bullet out. The air hole 30 is the aperture through which the high-pressure gas passes. The reduction of the aperture is conducive to the acceleration of the high-pressure gas and is easier to form an impact. The spring bayonet 24 is where the end of the first spring 8 on the sliding shuttle tube 7 is fixed. When the sliding shuttle tube is pushed forward, it begins to compress. After the bullet is fired, the elastic potential energy is released and converted into kinetic energy to rebound the sliding shuttle tube. The sliding column 21 cooperates with the inner circumferential surface of the front end outlet of the cylinder part in the pressure regulating system, so that the high-pressure airflow pushes the sliding column 21 forward. It should be noted that the length of the sliding column 21 is less than the length of the front end outlet 16, so that the sliding column 21 can be pushed to separate from the front end outlet and release the high-pressure gas. The inner circumferential surface of the tube body 20 cooperates with the outer circumferential surface of the front end outlet of the cylinder part, and its length is greater than the length of the front end outlet, so that when the sliding column is separated from the front end outlet, a closed space is still formed outside. The cooperation here and the above-mentioned two places has the highest precision requirements in the whole device.

[0046] Among them, the first spring 8 is to realize the retreat action of the sliding shuttle tube 7. Before the critical point of bullet firing, a large amount of high-pressure gas is accumulated in the part after the pressure feed port of the sliding shuttle tube 7. After the bullet is ejected, a part of the high-pressure gas is consumed, and the air pressure value is instantly reduced, while the high-pressure gas supplied later has not been replenished. Since the barrel and the bullet chamber are connected to the external atmosphere, the instantaneous air pressure inside the sliding shuttle tube 7 will be lower than the atmospheric pressure, resulting in a pressure difference, which will force the sliding shuttle tube 7 to move backward. The sliding shuttle tube 7 will produce a backward displacement, so a cycle can be established. As long as the high-pressure gas is continuously supplied, the sliding shuttle tube 7 will continuously move forward and backward. When pushing the bullet forward, the bullet is fired, and the bullet is filled in the gap backward, so that the continuous firing of the bullet is realized.

[0047] Specifically, the chamber 10 is provided with a bullet loading port 10-1, the front end of the chamber 10 is connected to the gun barrel 25, the inner wall of the chamber 10 cooperates with the outer wall of the sliding shuttle tube 7, and the inner wall diameter of the bullet loading port 10-1 is slightly larger than the diameter of a single bullet.

[0048] In the present embodiment, the gun barrel 25 is the pipeline from which the bullet is ejected. Before the bullet is ejected, it will be continuously accelerated in the gun barrel. Therefore, the longer the gun barrel, the greater the speed of the bullet out of the chamber, and the power will also increase with the speed. The bullet loading port 10-1 is threadedly connected with the automatic filling device, and the inner circumferential surface diameter is slightly larger than the bullet diameter. The place where the chamber 10 accommodates the bullet, the inner circumferential surface of the chamber cooperates with the outer circumferential surface of the sliding shuttle tube 7, and its internal space can only accommodate one bullet. Therefore, only after the bullet in the chamber 10 is ejected, the next bullet will enter the chamber. The above gun barrel 25, the bullet loading port 10-1, and the chamber 10 are combined and assembled into the firing system of the unmanned aerial vehicle bullet continuous firing device, which can complete the key task of firing bullets.

[0049] The chamber 10 is a temporary location for accommodating bullets, where the bullets will be ejected by the sliding shuttle tube. The principle of this device is very simple, and it only needs to have a volume to accommodate bullets. However, it should be noted that its internal volume should be larger than the volume of one bullet and smaller than the volume of two bullets. This is a necessary guarantee to prevent more than two bullets from entering the chamber at the same time, resulting in firing errors.

[0050] From the above, it can be seen that the working process of the launch system 3 is: when the high-pressure gas comes out from the front end outlet of the pressure regulating system, it contacts the rear end surface of the sliding column. Since the two have a high degree of fit and a very small gap, the high-pressure gas pushes the sliding column to drive the sliding shuttle tube to move forward. When the sliding column is pushed away from the front end outlet by the airflow, the accumulated high-pressure gas flows forward rapidly from the air hole on the sliding shuttle tube. At this time, since the bullet has been stuck by the pressure feed port for a long time, it is suddenly impacted by the high-pressure rapid airflow from the rear and is subjected to a strong driving force, that is, it is launched.

[0051] After the bullet leaves the gun chamber, the sliding shuttle moves backwards under the action of the spring and pressure difference. At the same time, the automatic filling system pushes the next bullet into the chamber under the action of its internal spring and pressure difference, waiting for the next impact of the sliding shuttle. This cycle repeats, and bullets can be fired continuously.

[0052] Specifically, the magazine device includes a bottle body 27 with a bottle mouth 26, and the bottle mouth 26 is threadedly connected to the bullet loading port 10-1. A horizontally arranged support plate 28 is provided in the bottle body 27, and four third springs 29 are installed on the support plate 28. The four third springs 29 are symmetrically distributed with respect to the bottle body 27, one end of the four third springs 29 is fixedly connected to the bottle body 27, and the other end of the four third springs 29 is fixedly connected to the support plate 28.

[0053] The support plate 28 is in the shape of a cylinder, the diameter of the support plate 28 is smaller than the diameter of the inner wall of the bottle body 27, and the distance between the support plate 28 and the inner wall of the bottle body 27 is smaller than the diameter of a single bullet.

[0054] In the present embodiment, the bottle 27 is a cylindrical bottle-shaped structure, with a large space inside, and the overall structure is symmetrically distributed. The bottle mouth 26, through which the bullet is loaded inside or enters the chamber, has a diameter that can only accommodate a single bullet to pass through. The bottle mouth is engraved with threads, which can be connected with the chamber by threads. The bottle 27, whose main function is to store bullets, has a large volume and can accommodate about 111 bullets with a diameter of 10mm. The supporting plate 28 is a cylinder with a small height, and its diameter is smaller than the inner diameter of the bottle, and the spacing between the supporting plate 28 and the inner wall of the bottle 27 is less than the diameter of a single bullet 10mm, so the bullet can be prevented from falling from the gap, and its function is to press the bullet to enter the chamber below. Due to the adoption of the third spring 29, the bottle 27 can be placed on top or on the bottom.

[0055] The four third springs 29 are springs of the same specification and are symmetrically distributed with respect to the two symmetric planes of the device. When the third springs 29 are extended or retracted, the support plate 28 can be driven to move up and down. The elastic force of the third springs 29 is relatively large, and can reach two-thirds of the height of the bottle body when fully extended, and can accommodate the maximum number of bullets inside the bottle body when fully compressed.

[0056] The bottle body 27 is threadedly connected to the bullet chamber 10 in the gun barrel 25 to ensure the stability of the connection. In addition, the inner circumferential surface of the bullet chamber 10 is slidably connected to the outer circumferential surface of the sliding shuttle tube 7. Before the drone bullet continuous firing device works, there is already a bullet 31 in the bullet chamber. Therefore, after the bullet 31 is fired, the sliding shuttle tube 7 retreats, and a gap for a bullet will be created in the bullet chamber 10, and it is at this time that the automatic filling device starts to operate. Since the inside of the filling device bottle body is always subject to the elastic force of the third spring 29 when there are more bullets, when the front bullet is fired, due to the elastic force and the attraction caused by the instantaneous drop in air pressure in the bullet chamber, the next bullet will be immediately pushed into the bullet chamber to complete the filling.

[0057] Specifically, it also includes an auxiliary system, which includes a targeting device and a monitoring device.

[0058] In this embodiment, in order to make the drone bullet continuous launcher more effective in urban defense and combating crime, some equipment can generally be installed on the device for assistance. For this launcher, after corresponding structural and usage scenario analysis, a collimated sight can be used; in addition, the monitoring equipment requires good image quality and stable signal transmission, so that the relevant information of the enemy drone can be accurately identified, thereby preparing for future operations.

[0059] It should be noted that the function of the auxiliary system is to provide guidance for the launcher before, during and after the shooting process. The guidance here mainly refers to the information transmission between the aiming device and the monitoring device. Through this guidance function, the accuracy of the user's operation is improved to a greater extent.

[0060] In summary, the device uses drones as a platform and carries a non-metallic bullet continuous launcher to launch strikes against drones. Compared with previous anti-drone means such as missiles, anti-aircraft guns, snipers, and electromagnetic interference devices, this device has higher flexibility, does not cause damage to the ground and people, and saves manpower. In addition, it can improve the success rate of striking "low, slow, and small" aircraft.
