Abstract

The invention relates to the technical field of ships, and discloses a ship and a seabed door grille thereof. The seabed door grid includes a grid base and a grid rotatably assembled in the grid base. The grid base is provided with a first limiting structure for limiting the downward rotation of the grid on the left side of the rotating shaft. The right side of the rotating shaft is provided with a second limit structure for restricting the upward rotation of the grille. The grille is provided with a counterweight on the left side of the rotating shaft. The grille exerts an upward force on the torsion spring. In the present invention, counterweights are arranged on the grille, and after the grille of the seabed door is opened, the seabed door will not automatically close due to the presence of counterweights. When closing the sea door grill, the torsion spring can be used to exert an upward force on the sea door grill to provide assistance for closing the sea door grill. The invention helps to prevent the open sea door grille from closing itself, and at the same time helps the operator to close the open sea door grill.

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 ...
