Abstract

L'invention concerne un dispositif de commande à distance de bateau de sauvetage semi-submersible, comprenant un bloc de poids (12) et une bride de serrage de fixation (13). Le bloc de poids (12) est emmanché sur un câble métallique de commande à distance (11) et relié en coulissement au câble métallique de commande à distance (11). La bride de serrage de fixation (13) est emmanchée sur le câble métallique de commande à distance (11) au niveau de l'extrémité inférieure du bloc de poids (12). La bride de serrage de fixation (13) est fixée par serrage au câble métallique de commande à distance (11) pour limiter le bloc de poids (12), et la position de la bride de serrage de fixation (13) sur le câble métallique de commande à distance (11) est ajustable. Lorsque le bloc de poids (12) tombe dans un premier trou de montage (14), la bride de serrage de fixation (13) peut passer à travers le premier trou de montage (14) au niveau de l'extrémité supérieure d'un bateau de sauvetage (15). En continuant à tirer sur le câble métallique de commande à distance (11), un câble métallique de treuillage de bateau peut être synchronisé avec le câble métallique de commande à distance (11), et le bateau de sauvetage (15) est placé de manière régulière et en douceur sur la surface de l'eau. Le dispositif présente les avantages d'une structure simple, d'un faible coût et d'une faible charge de travail de construction.
