[0001] The invention relates to the technical field of unmanned target drone manufacturing, in particular to a catapult-type plateau-type unmanned target drone. Background Art

[0002] Unmanned aerial vehicle is referred to as "UAV", and its English abbreviation is "UAV". It is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. UAVs can be divided into military and civilian use according to their application areas. In the military, UAVs are divided into reconnaissance aircraft and target aircraft. In the civilian field, UAVs + industry applications are the real rigid demand for UAVs. At present, their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of UAVs themselves.

[0014] Preferably, a mounting bracket is installed at the rear end below the support base, and a hydraulic lifter is installed at the front end below the support base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention can drive the unmanned target aircraft to move through the movable slide rails and the storage slide on both sides of the ejection platform. The wire drum is connected to the storage slide by a connecting wire body. When the unmanned target aircraft is ready to eject, the electric power of the driving motor is used to drive the transmission rod to rotate, and the rotating transmission rod drives the connecting belt and the wire drum to rotate, so that the wire drum pulls the connecting wire body and pulls the storage slide to move to the rear end. When it moves to a certain position, the driving motor stops rotating to tighten the wire drum. A first cylinder is installed inside the ejection platform. The first cylinder uses its pneumatic force to drive the first pneumatic push rod and the first pneumatic push block to push the storage slide, so that it can strengthen the driving force required for ejection. The reset tension spring is stretched when the storage slide moves to the rear end. When the pulling force disappears, it resets and rebounds backward. The unmanned target drone is ejected to the front end under the action of the propulsion force and the reset elastic force. Generally, the target drone takes off with rocket boost. The use of piston engines will have the following problems: 1. Rockets are dangerous goods and have safety risks; rockets are disposable products, cannot be reused, and have high use costs; 2. The piston engine is used with a propeller. In plateau areas, the air is thin and the oxygen content is low, which will cause low propeller efficiency and low engine efficiency. Even due to the low oxygen content, it is easy to cause the engine to stall, which has a serious impact on the use of the target drone in the plateau; the piston engine cannot be re-ignited after being stalled in the air, and stalling in the air will cause safety accidents; the piston engine uses gasoline as fuel, but the vehicles of the troops are basically diesel vehicles, which will increase logistical difficulties for fuel supply and affect the frequency of use of the unmanned target drone in training. The present invention innovates in the take-off method and the engine. The take-off method uses catapult take-off, which has no safety risks and is simple to operate. The catapult can be reused, which reduces the use cost; the turbojet engine has little effect on altitude changes and meets the take-off and landing power requirements in plateau areas. The turbojet engine can be electronically ignited in the air to avoid the risk of parking in the air. The turbojet engine can use diesel as fuel and share fuel with military vehicles, eliminating the need for fuel supply. These two innovations make the unmanned target drone simple to operate, highly safe, and highly adaptable to plateaus. They accelerate the use of unmanned target drones in grassroots troops, make training scenarios more realistic, and greatly improve training results.

[0017] 2. The output end of the second cylinder is connected to the second pneumatic push rod through the second pneumatic push rod and the second pneumatic push block. The second cylinder drives the second pneumatic push rod and the second pneumatic push block to drive the pulley limit block, so that when the unmanned target drone is placed, its body pulley can be fixed by the pulley limit block to avoid sliding or offset of the unmanned target drone when it is placed.

[0018] 3. The magnetic block of the slide and the electromagnet can be used to fix the storage slide and the storage box by magnetic adsorption when they need to be placed. When they need to be moved, just disconnect the electricity of the electromagnet to make it lose its magnetism, so that the storage slide can be moved. The advantage of this is that it is convenient for users to fold and unfold, and the overall flexibility of folding and unfolding is enhanced.

[0019] 4. The fan can be used to blow off the foreign particles on the sliding table, so as to ensure that the storage slide will not be disturbed by the foreign particles when sliding. The cleaning block acts on the bottom to clean the sliding table when the storage slide slides, so that the sliding table remains smooth, further reducing the adverse effects of residual particulate impurities on subsequent ejection.

[0033] Furthermore, a fan mounting plate 34 is installed on the rear end face of the storage box 13, and a fan 35 is installed inside the fan mounting plate 34, and three fans 35 are installed.

[0039] Working principle: When in use, the unmanned target aircraft 9 can be driven to move through the moving slide rails 5 and the storage slide 8 on both sides of the ejection platform 2. The wire drum 24 is connected to the storage slide 8 by the connecting wire body 25. When the unmanned target aircraft 9 is ready to eject, the electric power of the driving motor 27 is used to drive the transmission rod 29 to rotate. The rotating transmission rod 29 then drives the connecting belt and the wire drum 24 to rotate, so that the wire drum 24 pulls the connecting wire body 25 and pulls the storage slide 8 to move to the rear end. When it moves to a certain position, the driving motor 27 no longer rotates the tightening reel 24, and a first cylinder 18 is installed inside the ejection platform 2. The first cylinder 18 uses its pneumatic force to drive the first pneumatic push rod 19 and the first pneumatic push block 20 to push the object slide 8, so that it can strengthen the driving force required for ejection. The reset spring 16 is stretched when the object slide 8 moves to the rear end. When the pulling force disappears, it rebounds backward, so that the unmanned target aircraft 9 is ejected to the front end under the action of the driving force and the reset elastic force. The output end of the second cylinder 36 is connected to the second pneumatic push rod 37 through the second pneumatic push rod 37. The pneumatic push block 38 is connected by transmission, and the second cylinder 36 drives the second pneumatic push rod 37 and the second pneumatic push block 38 to drive the pulley limit block 39, so that when the unmanned target drone 9 is placed, its body pulley 12 can be fixed by the pulley limit block 39, so as to avoid the unmanned target drone 9 from sliding or deflecting when placed. The slide magnetic block 31 and the electromagnet 32 ​​can be used to fix the storage slide 8 and the storage box 13 by magnetic adsorption when it is needed to be placed. When it is needed to be moved, it only needs to disconnect the electrical property of the electromagnet 32. That is, it can lose its magnetism, so that the storage slide 8 can be moved. The advantage of this is that it is convenient for users to fold and put away, and the overall folding and putting flexibility is enhanced. The fan 35 can be used to blow off the foreign particles on the sliding table 6, so as to ensure that the storage slide 8 will not be disturbed by the foreign particles when sliding. The cleaning block 40 acts on the bottom to clean the sliding table 6 when the storage slide 8 slides, so that the sliding table 6 remains smooth, and the adverse effects of residual particulate impurities on subsequent ejection are further reduced.
