[0006] To achieve the above purpose, the utility model adopts the technical scheme of:

[0007] A tool for ship seawater tank tightness detection, comprising a sealing plate and a pressing plate, a plurality of screw rods are arrayed on the sealing plate, the screw rods are perpendicular to the sealing plate, one end of the screw rod is fixedly connected with the sealing plate, the pressing plate is a king type structure, comprising a vertical pressing plate and a plurality of horizontal pressing plates evenly distributed along the length direction of the vertical pressing plate, two waist-shaped holes are symmetrically provided on both sides of the horizontal pressing plate, each waist-shaped hole corresponds to a screw rod, the other end of the screw rod penetrates the waist-shaped hole, and the nut is locked and fixed with the screw rod outside the horizontal pressing plate, two ends of the horizontal pressing plate side facing the sealing plate are provided with embedding grooves, and magnets are embedded in the embedding grooves.

[0008] Preferably, the length of the horizontal pressing plate is greater than the width of the seawater tank door, and the magnet is adsorbed to the outer surface of the seawater tank.

[0009] Preferably, the screw rod is provided with six.

[0010] Preferably, a gasket is arranged between the nut and the horizontal pressing plate.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. Without additional firework, cutting operation, reduce the test cost and operation difficulty, will not cause damage to the seawater tank.

[0013] 2. Before the nut and screw locking is fixed, through the adsorption of the magnet on the pressing plate, the screw rod penetrates the waist-shaped hole, the preliminary positioning of the sealing plate and the pressing plate is completed, without the assistance of the second person, the sealing operation of the seawater tank door can be quickly completed under the condition of one person operation, the test efficiency is greatly improved.
