Description
Technical field
The utility model relates to Aero-Space model, is specifically related to a kind of water rocket model.
Background technology
Rocket model is often used in physics teaching, for explaining the various knowledge such as demonstration acceleration, has the rocket model that various power is launched, meet the needs of people's study, but some rocket model is heavier, when landing due to acceleration of gravity, easily launching crew is damaged; Some model carries parachute, but not easily opens when landing, and does not have the effect slowing down sinking speed.。
Summary of the invention
For overcoming above problem, the utility model provides a kind of water rocket model that can release a parachute fast.
A kind of water rocket model of the present utility model, comprises rocket head, parachute, rocket body, empennage, sealing device, it is characterized in that: rocket body top is provided with circular groove, and rocket body top is connected with parachute by flexible cord; Rocket head inner hollow top is circular cone build, cone lower diameter is a bit larger tham fiery rocket body diameter, bottom is rounding bench-type, and the circular groove size on described rocket head bottom inverted round stage opening and rocket body top adapts and is embedded in the circular groove on rocket body top; Inverted round stage inclined-plane is on average provided with 3 air admission holes in described rocket head bottom; Described parachute is positioned in rocket head; Described rocket body bottom is provided with empennage; Described rocket body lower end seals opening part by sealing device.
The utility model structure is simple, reasonable in design, can release a parachute effectively fast, plays the speed slowing down rocket landing, the transmitting that available protecting is following and viewing personnel.
Accompanying drawing explanation
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model.
Accompanying drawing 2 is the main TV structure schematic diagrames of rocket body of the present utility model.
Accompanying drawing 3 is structural representations of rocket head of the present utility model.
With reference to the accompanying drawings: 1 rocket head, 2 parachutes, 3 rocket bodies, 4 empennages, 5 sealing devices, 11 air admission holes, 31 circular grooves.
Detailed description of the invention
With reference to the accompanying drawings 1, accompanying drawing 2, accompanying drawing 3, in conjunction with detailed description of the invention, the utility model is described in further detail.
A kind of water rocket model, comprise rocket head 1, parachute 2, rocket body 3, empennage 4, sealing device 5, it is characterized in that: rocket body 3 top is provided with circular groove 31 for inlaying rocket head 1, and rocket body 3 top is connected with parachute 2 by flexible cord, for slowing down rocket sinking speed; Rocket head 1 inner hollow top is circular cone build, cone lower diameter is a bit larger tham rocket body 3 diameter, bottom is rounding bench-type, and circular groove 31 size on described rocket head 1 bottom inverted round stage opening and rocket body 3 top adapts and is embedded in the circular groove 31 on rocket body 3 top; Inverted round stage inclined-plane is on average provided with 3 air admission holes 11 in described rocket head 1 bottom, backs down rocket head 1, be convenient to release a parachute 2 for entering air when rocket lands; Described parachute 2 is positioned in rocket head 1; Described rocket body 3 bottom is provided with empennage 4, for playing balanced action when rocket launching; Described rocket body 3 lower end seals opening part by sealing device 5, and described sealing device 5, can open automatically when continuous inflating pressure.
When using the utility model, put into rocket head 1 by folding for parachute 2, in rocket body 3, inject water or other liquid; Being supported by empennage 4 by rocket body 3 is vertically placed on level land; Utilize inflator to inflate pressurization by sealing device 5 pairs of rocket bodies 3, when pressure reaches maximum critical value, rubber stopper is washed open by atmospheric pressure, and water or liquid, from the ejection of rocket body 3 lower openings, form reaction force, rocket body 3 boosting gone up to the air; Because air is to the drag effect of rocket head 1 in rocket body 3 lift-off process, rocket head 1 is embedded in the circular groove 31 on rocket body 3 top always; After rocket body 3 rises to certain altitude, because the thrust of water or liquid disappears, the inertia of rocket body 3 terminates, under gravitational effect, rocket body 3 falls, now, the air admission hole 11 on rocket head 1 enters air and backs down rocket head 1, is that rocket head 1 is separated in rocket body 3, parachute 2 is opened, and makes rocket body 3 slowly land to ground.
The utility model structure is simple, reasonable in design, can release a parachute effectively fast, plays the speed slowing down rocket landing, the transmitting that available protecting is following and viewing personnel.
