Underwater air film anti-drag warhead, ground drilling anchor and breach emergency repair device
The invention relates to an underwater air film resistance reduction warhead, a ground drilling anchor and a breach emergency repair device.The underwater air film resistance reduction warhead comprises a warhead shell and a switch, an air supply chamber is arranged in the warhead shell, an air film generating hole capable of communicating the air supply chamber with the outside is formed in the warhead shell, an air supply assembly capable of generating jet airflow is arranged in the air supply chamber, and the switch is connected with the air supply assembly. The switch is connected with the air supply assembly to control the air supply assembly to spray air outwards through the air film generating hole after entering water so as to form an air film outside the bullet shell; the jet air flow can form an air film attached to the surface of the bullet shell outside the bullet shell in the advancing process, resistance generated by direct contact of a water body and the bullet shell is greatly reduced, a large amount of kinetic energy is reserved for the bullet shell to be inserted into soil later, and the problems that in the prior art, kinetic energy loss in water is too much, and the final drilling depth is not enough are solved.
本发明涉及一种水下气膜减阻弹头、钻地锚及决堤抢修装置，该水下气膜减阻弹头包括弹头壳体和开关，弹头壳体内部设有供气室，弹头壳体上设有可使供气室与外界连通的气膜生成孔，供气室内部设有可产生喷射气流的供气组件，开关与供气组件相连以控制供气组件在入水后通过气膜生成孔向外喷气以在弹头壳体外部形成气膜；而喷射气流会在行进过程中在弹头壳体外部形成贴附在其表面的气膜，极大地减少了水体与弹头壳体直接接触产生的阻力，为之后扎入泥土保留了大量的动能，解决了现有技术中在水中动能损耗过多，最终钻地深度不够的问题。
