The invention relates to a sectional type separation hood which comprises a base, a hood body, a protective cover, a fastener, a locking mechanism, an exploder and an annular energy-gathered cutting rope. The base, the head cover and the protective cover are all of shell structures and are coaxially mounted; the hood front section is of a conical structure, the hood middle section is of a cylindrical structure, the large-diameter end of the hood front section is connected with the hood middle section, and the hood middle section is arranged on the peripheral face of the base front section in a sleeving mode and fixedly connected with the base front section through a plurality of locking mechanisms; the shield is sleeved in the head cover, and the shield rear section is fixedly connected with the head cover middle section through a plurality of fasteners; the annular energy-gathered cutting rope is circumferentially fixed to the inner circumferential face of the tail end of the head cover front section and used for cutting off connection between the head cover front section and the head cover middle section, the locking mechanism loses efficacy under the separation counter-acting force, the shield and the head cover middle section and the head cover rear section move backwards relative to the base, and the inner circumferential face of the head cover rear section is fixedly connected with the outer circumferential face of the base middle section in a clamped mode and limited by the front end face of the base rear section. The occupied space and the mass are reduced to the maximum extent.

    本发明涉及一种分段式分离头罩,包括基座、头罩、护罩、紧固件、锁定机构、起爆器、环状聚能切割索;基座、头罩和护罩均为壳体结构且同轴安装;头罩前段为圆锥结构,头罩中段为圆筒结构,头罩前段大直径端与头罩中段连接,头罩中段套装在基座前段外周面上、且通过若干个锁定机构与基座前段固连;护罩套装在头罩内,护罩后段与头罩中段通过若干个紧固件固连;环状聚能切割索周向固定在头罩前段末端内周面用于切断头罩前段与头罩中段的连接,在分离的反作用力下锁定机构失效,护罩及头罩中、后段相对基座向后运动,头罩后段内周面与基座中段外周面卡合固连并由基座后段前端面限位。本发明最大限度降低占用的空间、质量。
