Abstract

The invention relates to the technical field of ships, and discloses a ship and a sea chest grating thereof. The sea chest grating comprises a grating base and a grating rotationally assembled in thegrating base, the grating seat is provided with a first limiting structure for limiting the downward rotation of the grating at the left side of the rotating shaft and is provided with a second limiting structure for limiting the upward rotation of the grating at the right side of the rotating shaft, the grating is provided with a balance weight at the left side of the rotating shaft, and the rotating shaft is provided with a torsional spring for applying the upward acting force to the grating at the right side of the rotating shaft when the grating rotates. According to the present invention,the balance weight is arranged on the grating, and after the sea chest grating is opened, a sea chest cannot be automatically closed due to the existence of the counter weight. When the sea chest grating is closed, the torsional spring can be used for applying the upward acting force to the sea chest grating, and the assistance is provided for closing the sea chest grating. According to the present invention, the self-closing of the opened sea chest grating can be prevented, and an operator can be helped to close the opened sea chest grating.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship and a seabed door grille thereof. Background technique [0002] The sea water used on board, such as ballast water, cooling water, fire fighting water, etc., is usually sucked from the sea tank. In order to prevent foreign objects from being sucked into the seawater tank, a seabed door grille must be installed on the sea opening of the seabed door. [0003] The Chinese utility model patent with the authorized announcement number CN203740098U discloses a submarine grid. The submarine grid includes a grid plate and a fixed frame connected to the grid plate. The middle part of the upper end of the grid plate is provided with a connecting hole arranged horizontally. Both sides of the grid plate are respectively provided with two pairs of connection holes arranged horizontally, a pair of connection holes arranged longitudinally are symmetrically arranged at the lower end of the ...
