[0029] Referring to FIGS. 1 to 7, a temporary sealing device (10) for a ship coaming according to the first embodiment of the present invention can be detachably coupled to the coaming (20) for temporary sealing of the coaming (20).

[0030] The coaming (20) may be a pipe-shaped structure installed in a through hole (H) provided for installing cables or piping in the bulkhead or deck (D) of the ship, but is not necessarily limited thereto.

[0031] The combing (20) may have a cross-sectional shape that is long in one direction. For example, the first inner diameter (D1) in the first direction (DR1) of the combing (20) may be larger than the second inner diameter (D2) in the second direction (DR2) of the combing (20).

[0032] The temporary sealing device (10) may include a sealing plate (100), a hook plate (200), a fixing bolt (300), a fixing nut (310), and a coil spring (400), and may further include a sealing layer (110), a pair of cushioning layers (210), a rigid washer (320), and / or a sealing washer (330).

[0033] The sealing plate (100) can be placed on the first stage opening (21) of the combing (20) and can cover the first stage opening (21) of the combing (20) on a flat surface as shown in FIG. 6.

[0034] A sealing layer (110) bonded to the sealing plate (100) may be disposed on the first surface (101) of the sealing plate (100). The sealing layer (110) may include an elastic material such as rubber.
