The invention discloses a hoisting and releasing device and method for seabed geophysical observation, and relates to the technical field of hoisting and releasing devices.The hoisting and releasing device comprises a frame and supporting legs, a hoisting ring is arranged on the outer wall of each supporting leg, and a butt joint connector, a tightening ground gripping mechanism and a reverse thrust unhooking piece are arranged between each hoisting ring and the corresponding supporting leg. According to the anti-thrust unhooking device, by arranging the anti-thrust unhooking piece, when a traction block moves downwards, a second rack is driven to move downwards, so that a straight gear is driven to drive a rotating shaft to rotate, and then a first rack is shifted to drive an anti-thrust ring to move upwards through a special-shaped rod and a second L-shaped pulling block; and when the reverse thrust ring continues to move upwards, the hoisting ring is pushed out of the supporting leg, so that the hoisting ring is not in contact with the supporting leg any more, the supporting leg can be completely released to the seabed, meanwhile, the hoisting ring cannot be pulled when the hoisting ring is released from the supporting leg, and the stability of the released frame is improved.
本发明公开了一种海底地球物理观测用的吊装释放装置及其方法,涉及吊装释放装置技术领域,包括框架,支撑腿,每个所述支撑腿的外壁设置有吊装环,所述吊装环与所述支撑腿之间设置有对接连接器,收紧抓地机构,反推脱钩件。本发明通过设置反推脱钩件,当牵引块向下移动的同时带动第二齿条向下移动,从而驱动直齿轮带动旋轴进行转动,进而拨动第一齿条通过异形杆与第二L形拉扯块带动反推环向上移动,当反推环与吊装环底部接触时,反推环继续向上移动时将吊装环从支撑腿外部推出,使得吊装环不再与支撑腿接触,以此使得支撑腿能够完全释放到海底,同时使得吊装环在与支撑腿释放时不会被拉扯,以此提高了框架释放后的稳定性。
