Abstract
(EN)
Disclosed is an electromagnetic thrower, comprising a thrower launch canister (1) and a control device (2), wherein the control device (2) is fixed to a tail end of the thrower launch canister (1); a stable support frame (3) capable of reducing the launch recoil force is fixed to the bottom of the thrower launch canister (1); the thrower launch canister (1) is internally provided with an armature (4); and the tail end of the thrower launch canister (1) is provided with a negative pressure hole (22). The electromagnetic thrower is mainly used in civil fields such as compressed life buoys, cable balls, anchor hooks and nets (for capturing prey). By means of the cooperation between the stable support frame (3) that is capable of reducing the launching recoil force and the negative pressure hole (2), when the thrower launching canister (1) drives the armature (4) to advance, the recoil force generated by the thrower launching canister is effectively reduced, so as to achieve more stable throwing and a more accurate throwing range.

L'invention concerne un lanceur électromagnétique, comprenant une cartouche de lancement de lanceur (1) et un dispositif de commande (2), ce dispositif de commande (2) étant fixé à une extrémité de queue de la cartouche de lancement de lanceur (1) ; un cadre de support stable (3) permettant de réduire la force de recul de lancement est fixé au fond de la cartouche de lancement de lanceur (1) ; la cartouche de lancement de lanceur (1) est pourvue intérieurement d'un induit (4) ; et l'extrémité de queue de la cartouche de lancement de lanceur (1) est pourvue d'un trou de pression négative (22). Ce lanceur électromagnétique est principalement utilisé dans des domaines civils, comme pour des bouées de sauvetage comprimées, des billes de câble, des crochets d'ancrage et des filets (pour la capture de proies). Au moyen de la coopération entre le cadre de support stable (3), qui permet de réduire la force de recul de lancement, et le trou de pression négative (2), lorsque la cartouche de lancement de lanceur (1) amène l'induit (4) à avancer, la force de recul générée par la cartouche de lancement de lanceur est efficacement réduite, ce qui permet d'obtenir un lancement plus stable et une portée de lancer plus précise.

一种电磁抛投器,包括抛投器发射筒(1)和控制装置(2),其中控制装置(2)固定在抛投器发射筒(1)尾端,且抛投器发射筒(1)底部固定有可以减小发射后坐力的稳定支撑架(3),抛投器发射筒(1)内设有电枢(4),且抛投器发射筒(1)尾端开有负压孔(22)。该电磁抛投器主要用于压缩救生圈、缆球、锚钩和网(抓捕猎物)等民用领域所采用,通过可以减小发射后坐力的稳定支撑架(3)和负压孔(2)的配合作用,使抛投器发射筒(1)在驱动电枢(4)前进时,有效的减少其产生的后坐力,从而使其抛投更加稳定,抛投范围更加精准。
