The device comprises a base, a head cover, a protective cover, a locking mechanism, an annular energy-gathered cutting rope, an exploder and a cutting pin. The base, the head cover and the protective cover are all shells and are coaxially mounted; the large-diameter end of the hood front section of a conical structure is connected with the hood middle section; a plurality of continuous weakening grooves are uniformly distributed in the inner circumferential surfaces of the middle and rear sections of the hood in the circumferential direction; the hood rear section is fixedly sleeved on the outer peripheral surface of the base front section; the shield is sleeved in the head cover, and the shield middle section is fixedly connected with the head cover middle section through a plurality of locking mechanisms; a cutting pin matched with the weakening groove is fixed at the middle section of the shield; the annular energy-gathering cutting rope is fixed to the tail end of the front hood section and used for cutting off the connection between the front hood section and the middle hood section, the locking mechanism fails under the separation counter-acting force, the shield and the cutting pin move backwards, the cutting pin cuts off the weakening groove, the middle hood section and the rear hood section are cut and sectioned, and the middle hood section and the rear hood section are separated from the base. The shield rear section is fixedly connected with the base front section in a clamped mode and limited by the end face of the base rear section. The occupied space and the mass are reduced to the maximum extent.

    本发明包括基座、头罩、护罩、锁定机构、环状聚能切割索、起爆器和切割销;基座、头罩、护罩均为壳体且同轴安装;为圆锥结构的头罩前段大直径端与头罩中段连接;头罩中、后段的内周面周向均匀布设若干个连续的削弱槽;头罩后段套装固定在基座前段外周面;护罩套装在头罩内,护罩中段与头罩中段通过若干个锁定机构固连;与削弱槽配合的切割销固定在护罩中段;环状聚能切割索固定在头罩前段末端用于切断头罩前段与头罩中段的连接,在分离反作用力下锁定机构失效、护罩及切割销向后运动,切割销切断削弱槽将头罩中、后段切割分瓣使其与基座分离,护罩后段与基座前段卡合固连并由基座后段端面限位。本发明极大限度降低占用的空间和质量。
