Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The invention is mainly used for hydraulically assisted launching of UAVs. This device can give UAVs a certain initial speed. When the initial speed given by the system is greater than the minimum speed requirement for UAVs to take off, UAVs leave the ejection device to complete the take-off action.

[0037] After the device is initialized, the base 1 is fixed on the ground and other objects with strong stability, and the required initial launch position is reached by rotating the chassis 2 . Then adjust the position of the launch height adjustment rod 6 in the adjustment rod groove 5 to obtain the desired initial launch height. The required launch UAV is placed on the stage 9, and the launch preparations are now ready. 13 The hollow piston rod moves forward to compress the compression spring 11, so that the compression spring 11 generates el...

Abstract

The invention discloses an auxiliary hydraulic catapult for an unmanned aerial vehicle. The auxiliary hydraulic catapult comprises a chassis, a base, a launching height adjusting rod, a launching padand the like. The spring device is ingeniously utilized; energy generated in the dynamic change process of the hydraulic device is accumulated into huge elastic potential energy, the huge elastic force generated in the deformation recovery process of the strong spring is transmitted to the unmanned aerial vehicle needing to be catapulted, the unmanned aerial vehicle is endowed with a high initialspeed in the process, and therefore the purpose of catapulting the unmanned aerial vehicle is achieved. The related device designed by the invention has a related structure for adjusting the orientation, and can be adjusted to the required emission orientation in a short time. While the launching direction is adjusted, the system can also adjust the structure of the hydraulic rod, and therefore elastic potential energy is accumulated. By means of the independent module design, the emission waiting time interval can be effectively reduced, the emission efficiency is improved, and better economic benefits are obtained.

Description

technical field [0001] The invention relates to a hydraulic ejection device, which is mainly used for auxiliary launching of unmanned aerial vehicles and the like, and belongs to the technical field of unmanned aerial vehicle design. Background technique [0002] A catapult is a device that applies a corresponding initial velocity to the projected object by relying on its own power or external power. It is mainly used for launching rockets, missiles, and drones. With the rapid development of ejection technology, ejection devices are also showing a trend of diversification. According to the classification of launch power, they are mainly divided into cold launch and hot launch. [0003] The traditional high-pressure air ejection system mainly includes a high-pressure air source, a control valve group, and an ejection power device. The ejection power unit usually consists of pneumatic transmission, braking and synchronous lever mechanism. Through the control signal, the valv...
