Abstract

Pour résoudre les problèmes selon lesquels des dispositifs d'échantillonnage existants sont instables en fonctionnement, ne peuvent pas mettre en œuvre un échantillonnage à tout moment, et sont tout à fait inadéquats au fonctionnement, un dispositif d'échantillonnage de sol rocheux pour une étude géologique marine est proposé, se rapportant au domaine technique de l'échantillonnage de sol rocheux. Le dispositif comprend une plaque de poussée (1) ; deux poignées de poussée (2) sont disposées sur le côté gauche de la plaque de poussée (1) ; deux pieds de support (5) sont disposés au fond de la plaque de poussée (1) ; des plaques verticales (8) sont montées de manière fixe à l'extrémité droite de la plaque de poussée (1) ; des roues universelles (6) sont disposées au niveau des extrémités inférieures des plaques verticales (8) et des deux pieds de support (5) ; quatre roues universelles (6) sont chacune pourvues d'un patin de frein ; une plaque supérieure (10) et une plaque inférieure (11) sont montées coulissantes sur les côtés droits des plaques verticales (8) ; une colonne de même rotation (12) est montée rotative sur la plaque supérieure (10) et la plaque inférieure (11) ; une palette hélicoïdale (13) est montée fixe sur le côté extérieur de la colonne rotative (12) ; un cylindre en forme de cône tronqué (15) est relié de façon mobile sur le côté extérieur de la colonne rotative (12) ; deux moteurs de tige de poussée (14) sont intégrés symétriquement dans la plaque inférieure (11). Le dispositif d'échantillonnage a une structure simple, est pratique à utiliser et peut fonctionner de façon stable, et peut mettre en œuvre un échantillonnage à n'importe quel moment.
