The invention discloses a shock excitation device for marine seismic exploration, which comprises a sealed shell, cavities are formed in the positions, close to the front side and the rear side, of an inner cavity of the sealed shell, drainage ports are formed in the positions, close to the bottom, of the front side and the rear side of the sealed shell, and the drainage ports and the cavities are arranged in a mutually-communicated manner. According to the piezoelectric geophone, through mutual cooperation of a rotating belt, a driving gear, a rotating shaft, a transmission rod, a driven gear, a transmission gear, a flow guide plate, a guide plate and other parts, when a ship drives the piezoelectric geophone body to move at a high speed, the piezoelectric geophone body can be driven to move at a high speed; water flow can penetrate through the cavity to drive the rotating blades to rotate, and the rotating blades drive the driving gear to rotate through the rotating shaft, so that a plurality of rotating belts are driven to rotate, and surrounding fish schools are expelled.
本发明公开了一种用于海洋地震勘探的激震装置,包括密封外壳,所述密封外壳内腔靠近前后两侧处均开设有空腔,所述密封外壳前后两侧靠近底部处均开设有排水口,且所述排水口与空腔为相互贯通设置,所述密封外壳底部固定连接有环形箱,所述环形箱的内腔有变压器,本发明通过旋转带、主动齿轮、转轴、传动杆、从动齿轮、传动齿轮、导流板、导向板等部件之间的相互配合,可实现当船只带动压电地震检波器本体进行高速移动时,水流会穿过空腔带动旋转叶片进行旋转,旋转叶片通过转轴带动主动齿轮旋转,从而带动若干旋转带进行旋转,从而对周围的鱼群进行驱逐。
