所述的主壳体包括外壳、密封舱、隔腔、线圈舱和储电舱。自上而下分别为密封舱、隔腔、线圈舱和储电舱。拉杆穿过密封舱在隔腔内发生上下的往复运动。
主壳体下端固定在海底或固定在海洋结构物上，也可以根据实际情况使用拉钩和系泊缆绳进行固定。当主壳体固定在海底时，拉杆可以配合较小的浮体，将浮体调节至海面，当波浪带动浮体上下运动时，拉杆和主壳体产生相对运动，或将拉杆与系泊缆绳进行配合。
所述拉杆包括拉环、运动杆和防脱环部分组成。拉环用于连接不同的运动结构，防脱环用于放置运动幅度过大破坏主壳体内的结构，运动杆部分穿过密封舱深入主壳体的隔腔内，当发生直线运动时，带动永磁体发生往复的直线运动。
所述密封舱内设置多个凹槽，布置Y型密封圈，Y型密封圈的内缘与拉杆接触，外缘在密封舱的凹槽内，由于密封圈具有一定的柔度，当拉杆往复直线运动时，内缘发生往复变化，但始终贴合在拉杆上。
所述永磁体沿运动杆轴向布置多个，具体数量可以根据需要进行调节，永磁体和运动杆通过平键进行配合。
所述的线圈固定安装在主壳体的线圈舱内，通过隔腔与永磁体隔开，在隔腔进水的 情况下能够保证线圈的密封，不会影响装置的正常发电。
所述的恢复弹簧布置在隔腔的底部，与拉杆的底部连接，当拉杆受到载荷被拉出外壳时，由于拉杆防脱环的存在，相对运动停止，载荷消失后恢复弹簧将拉环拉回原位。
有益效果：本发明的水下直线发电装置，具有以下优点：
1.该具有隔腔的水下直线发电装置能够将海洋结构物附近的水下和水面直线运动和波浪引起的升沉运动的能量转化为电能加以利用。
