A ship tightness test device according to claim 6, wherein: the pressing plate (104) is provided with a groove matched with the pressing block (106), a gap is arranged between one end, connected with the first electric telescopic rod (105), of the pressing block (106) and the groove, an exhaust hole (107) communicated with the outside of the pressing plate (104) is formed in one side of the position, located between the pressing block (106) and the gap, of the groove, and a through hole (108) is formed between one end, connected with the first electric telescopic rod (105), of the pressing block (106) and the second groove (801).
8. A method of using the ship tightness test apparatus as claimed in claim 7, comprising the steps of:
step one: starting a motor (101) to enable an opening of a placing groove (103) on a test box shell (102) to be in a horizontal direction, placing a kayak in the placing groove (103), installing a test box sealing cover (2) to enable the placing groove (103) to form a sealed space, starting a hydraulic cylinder (203) on one side of the test box shell (102), extruding one side of the kayak, starting an electric telescopic rod (105) on the other side of the test box shell (102), enabling a pressing block (106) to move to extrude the kayak, enabling a gap between the two pressing blocks (106) to enable the kayak to leave a place which is not contacted with the pressing plate (104) and the pressing block (106), enabling the discharged air to enter the first rubber bag (302) through an air outlet (301) on the other side if the kayak has air leakage, enabling the first rubber bag (302) to expand under the stress, extruding a pressure sensor (303) when the extruding force reaches a set value of the pressure sensor (303), and triggering the pressure sensor (303);
step two: the hydraulic cylinder (203) drives the pressing plate (104) to reset, the hydraulic cylinder (203) at the other side of the test box shell (102) is started, the electric telescopic rod (105) in the reset pressing plate (104) is started, the pressing block (106) extrudes the rubber boats, then the electric telescopic rod (105) is started to reset the pressing plate (104), the motor (101) is started to drive the test box shell (102) to rotate, the rubber boats incline in the placing groove (103), the position changes, the process is repeated, and the contact place between the rubber boats and the pressing block (106) is changed;
step three: when the first groove (5) on the pressing block (106) completely covers the air leakage hole of the rubber boat, the outer surface of the pressing block (106) is tightly contacted with the rubber boat in the process of extruding the rubber boat, so that a closed space is formed by the first groove (5), the pressure in the first groove (5) is increased by extruding the rubber boat, the sealing plate (701) is moved out of the air inlet (501), so that the air inlet (501) is opened, the air leaked from the rubber boat enters the limiting groove (502) through the air inlet (501), and then enters the second rubber airbag (802) through the air transmission pipeline (8), and the second rubber airbag (802) is inflated;
step four: and starting the second electric telescopic rod (702) to push the limiting plate (7) to move, so that the air inlet (501) is opened, and air in the second rubber air bag (802) is discharged.
