The invention discloses a maintenance tightness detection device and method for a discharge outboard short pipe of an underway ship, and the device enables the discharge outboard short pipe to be exposed out of the water surface in a manner of adjusting ballast water when the discharge outboard short pipe leaks or is damaged, can cut and replace a damaged pipe section on the discharge outboard short pipe in a cabin, and carries out the maintenance of the discharge outboard short pipe. And then, the tightness detection device is mounted in the repaired outboard short pipe to carry out tightness test on the outboard short pipe, so that the problem that the risk coefficient is high when a frogman carries out underwater maintenance operation outside a ship is effectively solved.

    本发明公开了一种在航船舶排舷外短管维修密性检测装置及方法,本发明在排舷外短管出现渗漏或破损时,通过调整压载水的方式使排舷外短管露出水面,在机舱内即可将排舷外短管上的破损管段切割替换掉,对其进行维修,然后将密性检测装置安装在维修好的排舷外短管内对其进行密性试验,有效地解决了蛙人水下在船外维修作业所面临的风险系数高的问题。
