Description

一种船舶舱室密性检验装置及检验方法A device and method for testing the tightness of a ship's cabin

技术领域technical field

本发明属于船舶建造技术领域，具体涉及一种船舶舱室密性检验装置及检验方法。The invention belongs to the technical field of ship building, and in particular relates to a ship cabin tightness inspection device and inspection method.

背景技术Background technique

船舶舱室密性试验的目的是为了检验船体分段建造过程中的焊缝密性和结构强度，通常采取水压试验、气密试验、真空试验等方式检验。The purpose of the ship compartment tightness test is to test the weld tightness and structural strength during the construction of the hull section, usually by means of hydrostatic test, airtight test, vacuum test and other tests.

对于船舶分段建造环节来说，主要的舱室密性是以气密为主。常用的技术手段是使用门盖将舱室门封闭住，继而向舱室内部加压到一定数值后，观察一端时间再进行显色试验，验证船体舱室密性。此种方式一方面由于需要在门盖上安装进气孔，破坏门盖本体结构，此外由于加压过程中，门盖多采用铰链连接，高压之下存在变形的问题，致使试验结束后，拆除也有一定工作量。再者，由于试验过程中依赖于压力计的读数，无法快速直观反应舱内压力变化情况，给试验环节的安全问题增加不确定性。For the segmental construction of ships, the main cabin tightness is mainly airtight. The commonly used technical method is to use the door cover to close the cabin door, and then pressurize the interior of the cabin to a certain value, observe the time at one end and then conduct a color test to verify the tightness of the hull cabin. On the one hand, this method needs to install an air inlet on the door cover, which will damage the structure of the door cover. In addition, during the pressurization process, the door cover is mostly connected by hinges, and there is a problem of deformation under high pressure, which leads to the removal of the door cover after the test. There is also a certain amount of work. Furthermore, since the test process relies on the readings of the pressure gauge, it is impossible to quickly and intuitively respond to the pressure changes in the cabin, which adds uncertainty to the safety of the test process.
