Description

Steam ejection device applied to glider Technical Field The utility model relates to the technical field of aerospace, in particular to a steam ejection device applied to a glider. Background The traditional takeoff mode of the glider mainly comprises the steps of transporting the glider to a higher place, and then obtaining enough glide speed by utilizing high-altitude potential energy, wherein the takeoff cost is high. In addition, the takeoff conditions of the glider are high in environmental requirements, and a mountain high enough to realize the gliding takeoff is needed. Because of its cost and environmental limitations, gliders cannot be widely used as an entertainment item, resulting in low popularity and utilization of gliders. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides a steam ejection device applied to a glider, which aims to reduce the requirements and cost of the takeoff environment of the glider. The technical scheme includes that the steam ejection device for the glider comprises a flight runway, a steam tank and an ejection system, wherein two sliding grooves are formed in the flight runway, the ejection system is arranged below the flight runway, the ejection system comprises a sliding shuttle and two parallel guide steel pipes, guide grooves are formed in the guide steel pipes, open grooves are formed in the pipe walls of the guide steel pipes, one ends of the guide steel pipes are connected with the steam tank through air pipes, hydraulic buffer grooves are formed in the other ends of the guide steel pipes, steam valves are arranged on the air pipes, pistons are arranged at the lower ends of the sliding shuttle and are in sliding fit with the guide grooves, and connecting plates are arranged at the upper ends of the sliding shuttle and penetrate through the sliding grooves and are connected with a front wheel of the glider through connecting rods. Based on the above, the high-temperature and high-pressure steam is generated by the steam tank to serve as ejection power to push the shuttle to carry the glider to carry out ejection and take off, and the guide steel pipe is used for guiding the shuttle. Through the mode, the glider can take off without being transferred to a high place, the requirement of the glider on the environment is reduced, and meanwhile, the take-off cost is reduced, so that the glider can be widely popularized in various areas. In addition, the guide steel pipe is used as a guide pipe to guide the shuttle, the strength of the guide steel pipe is suitable for the take-off of a glider, and the manufacturing cost is low. Further, a shuttle resetting device is arranged at the starting end of the flying runway, the shuttle resetting device comprises a winding motor, and the winding motor is connected with the shuttle through a steel wire rope. Based on the above, after the shuttle is ejected, the winding motor winds the steel wire rope, and the shuttle returns to the initial position under the driving of the steel wire rope. Further, a pressurizing tank is further arranged between the steam tank and the guide pipe. Based on the above, the steam generated by the steam tank is further pressurized by the pressurizing tank, so that the glider can obtain larger initial kinetic energy when catapult-assisted take-off. Further, the hydraulic buffer tank comprises a buffer plug, a hydraulic inner cavity and a hydraulic outer cavity, an orifice is arranged between the hydraulic inner cavity and the hydraulic outer cavity, a movable partition plate is arranged on the hydraulic outer cavity, hydraulic oil is filled in the hydraulic inner cavity and the hydraulic outer cavity, and a reset spring is arranged between the movable partition plate and the inner wall of the hydraulic buffer tank. Based on the above, after the glider takes off, the piston still moves until the piston rotates to the buffer plug, hydraulic oil in the hydraulic inner cavity enters the hydraulic outer cavity through the throttle hole under the extrusion of the buffer plug, the movable partition compresses the return spring under the extrusion of the hydraulic outer cavity, and finally the effect of buffering and stopping the piston is achieved. And after the piston stops, the return spring pushes the movable partition plate to return, so that the buffer plug is pushed to return. Further, the runway is made of steel plates. Based on the above, the runway made of the steel plate has sufficient hardness. In order to more clearly illustrate the above-mentioned features of the present utility model and its intended objects, the present utility model will be further described with reference to the accompanying drawings and examples.
