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.
