Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0024] The ship tightness test device in the embodiment of the present invention is used for tightness test on the weld section 100 of the ship. The structure of the test device is as follows figure 1 As shown, it includes a vacuum cover 1 positioned on the weld section 100, the vacuum cover 1 is made of plexiglass with a thickness of about 10 mm, a sponge 3 is arranged between the vacuum cover 1 and the weld section 100, and the sponge 3 is opened with a The notch of the weld exposing the weld segment 100 . The top of the vacuum cover 1 is communicated with a suction joint 2, the suction joint 2 includes a compressed air delivery pipe 21 and a suction pipe 22, one end...

Abstract

The invention discloses a tightness test device of a ship. The tightness test device is used for the tightness test of the welding line section of the ship and comprises a vacuum cover positioned on the welding line section, the top of the vacuum cover is communicated with an air exhausting connector; the air exhausting connector comprises a compressed air conveying pipe and an exhausting tube, one end of the exhausting tube is vertically mounted on the vacuum cover and the other end of the exhausting tube is communicated with the compressed air conveying pipe; the compressed air conveying pipe is obliquely arranged relative to the exhausting tube, a compressed air inlet is formed in the lower end of the compressed air conveying pipe and a compressed air outlet is formed in the higher end of the compressed air conveying pipe. The pre-tightness test of the corner welding line and butted seam of the partial cabin can be achieved by the tightness test device of the ship during the segmented manufacturing stage, so that the difficulty that the tightness test can be carried out only after all cabin structures are completed in the prior art can be solved and the tightness test process can be carried out in advance.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship tightness test device. Background technique [0002] In shipbuilding, due to the limitations of segmented manufacturing, after the segmental manufacturing is completed, except for a few small cabins that can complete the cabin air tightness test, other watertight welds need to be assembled or closed before the leak test can be performed. . This expands the working scope of the tightness test, which is not conducive to the integrity of the segmental coating and prolongs the construction period of the berth; and with the higher requirements of the shipowner and ship inspection for the quality of shipbuilding, especially the quality requirements of weld seams Increasingly, other alternative methods such as flushing test or kerosene test are limited by themselves and are no longer competent. [0003] Therefore, it is necessary to provide a ship tightness test device that can b...
