The invention discloses an overpressure protection device of a water ballast tank. The overpressure protection device is installed on a shell of the water ballast tank. The overpressure protection device comprises a fence which forms a ring body, wherein the peripheral side of the fence is fixedly connected to the shell and communicates with the inner side and the outer side of the shell; at leastone release mechanism which comprises a shearing pull rod, a shearing seat and a shearing pin, wherein one end of the shearing pull rod is fixedly connected with the fence, the other end of the shearing pull rod is inserted into the shearing seat in the axial direction of the shearing pull rod, and the shearing pin is inserted into the shearing pull rod and the shearing seat in the radial direction of the shearing pull rod; a cover plate which is fixedly connected with the shearing seat and blocks the fence to separate the inner side and the outer side of the shell. When the pressure difference between the inner side and the outer side of the shell is larger than the preset pressure difference, the shearing pin is sheared off, the shearing pull rod is separated from the shearing seat, andthe cover plate unblocks the fence. When the pressure in the water ballast tank is too large, the release mechanism releases the blocking of the cover plate to the fence, so that the water ballast tank rapidly drains to reduce the pressure, and the structure of the water ballast tank is further protected from being damaged.

    本发明公开了一种压载水舱的超压保护装置,其用于安装在压载水舱的外壳上;超压保护装置包括:围栏,其围合形成一环体;围栏的外周侧固连在外壳上,且连通外壳的内外侧;至少一个释放机构,释放机构包括剪切拉杆、剪切座、剪切销,剪切拉杆的一端与围栏固连,另一端沿剪切拉杆的轴向插设于剪切座中,剪切销沿剪切拉杆的径向插设于剪切拉杆、剪切座上;盖板,其与剪切座固连,并封堵围栏以隔断外壳的内外侧;当外壳的内外侧的压差大于预设压差时,剪切销剪断,剪切拉杆与剪切座脱离,解除盖板对围栏的封堵。本发明在压载水舱内的压力过大,释放机构解除盖板对围栏的封堵,使得压载水舱快速泄流以减压,进而保护压载水舱的结构不被破坏。
