Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples.
The embodiment provides a crossbow shooting model rocket system, which utilizes a model rocket to replace an arrow, and comprises a crossbow shooting system and a model rocket system.
As shown in fig. 1(a), (b), the shooting system may employ a conventional bow, including a bow body 1, a bow string 2, a trigger 3, and a bow string hook 4. The bow body 1 is provided with a guide groove which is matched with one fin of the model rocket system, and the fin is fixed on the model rocket, so that the model rocket system can be ensured to move along the guide groove without deviating from the direction.
As shown in fig. 2, the model rocket system includes a model rocket body, a model rocket solid engine 6 and a remote power-on device. The model rocket solid engine 6 and the remote electrifying device are both arranged in the model rocket body to form the model rocket, the propellant of the model rocket system adopts a solid propellant, and the model rocket is pushed to advance by the reaction force generated by the combustion backward injection of the solid propellant.
The remote electrifying device is used as a circuit switch, is in an open circuit state in a storage state, is conducted only after the model rocket system moves a certain distance on the crossbow shooting system, and ignites the model rocket solid engine 6. The remote electrifying device comprises a time-delay battery system 5, a lead 7, a pull circuit system 8, a pull ring 10, a pull rope 11 and an electric ignition head 9. As shown in fig. 3, the pull-out circuit system 8 is composed of two conductive sheets 12 and an insulating sheet 13, wherein the insulating sheet 13 is disposed between the two conductive sheets 12, so that the two conductive sheets 12 are not contacted with each other and are not conductive; one end of a pull rope 11 is connected with an insulating sheet 13 through a pull ring 10, and the other end of the pull rope 11 is fixed on a crossbow; the delay battery system 5 is electrically connected with the conducting strip 12 through a lead 7 and provides energy and delay time for the delay ignition of the electric ignition head 9; the conducting strips 12 are communicated with the ignition head 9 through the conducting wires 7, and after the two conducting strips 12 are conducted, the electric ignition head 9 is ignited after the delay battery system 5 delays power supply.
In the state of not being put on the shelf, the insulating sheet 13 isolates the two conducting sheets 12, so that the whole ignition circuit is in an open circuit state, and the electric ignition head 9 cannot ignite; after the model rocket system is placed on a crossbow, a pull rope 11 fixed on a crossbow shooting system is fixed on a pull ring 10, but the pull rope 11 is not tensioned, and at the moment, the whole ignition circuit is still in an open circuit state; and (3) pulling the trigger 3, sliding the wing piece of the model rocket system along the guide groove of the bow body 1, and launching the model rocket system through ejection action to ensure that the model rocket system obtains enough initial speed. When the model rocket system is ejected by the crossbow system, leave one distance from the original point, the stay cord 11 fixed on the crossbow system pulls the insulating sheet 13 away from the two conducting sheets 12 through the pull ring 10, the two conducting sheets 12 contact with each other at the moment, so that the whole ignition circuit is switched on, but the delay battery system 5 is provided with a capacitor to delay power supply, the delay battery system 5 is provided with power supply at a certain time within 0-4 s, so that the electric ignition head 9 is ignited, the model rocket solid engine 6 is ignited, the model rocket system is pushed to move, and the flight track is seen by the trace left by the flight smoke.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
