Abstract

The invention discloses an embedded grille cover, which comprises: a cover plate placed on the deck of a ballast tank and used to cover a manhole on the deck; two fixing components, arranged at intervals on the cover plate One side, and each of the fixing components includes: a fixing plate, one end of the fixing plate is used for fixed connection with the deck; a connecting plate, one end of the connecting plate is pivotally connected to the fixing plate The other end, the other end of the connecting plate is fixed to one side of the cover plate. The present invention is convenient to open or close the cover plate, so that it is convenient to open the cover plate when it is necessary to enter the ballast tank for maintenance. Falling into the manhole will cause danger, which improves safety; at the same time, the connection between the cover plate and the deck is firm and the reliability is high, and the cover plate has an anti-slip effect, which can prevent workers from slipping and falling.

Description

technical field [0001] The invention relates to a buried grill cover. Background technique [0002] Ballast tank is the general term for the cabins used to hold ballast when the ship is empty. Ballast is heavy material, usually seawater, that stabilizes a ship for maneuverability. Compartments for this purpose include double bottom deep tanks and wing tanks. When not ballasted, these compartments can hold fresh water, fuel oil or even cargo, depending on the tank and type of vessel. A permanent maintenance passage is generally provided in the ballast tank, and of course, in order to facilitate maintenance personnel to enter the passage, a manhole is generally provided on the deck of the ballast tank. Simultaneously, in order to prevent the staff from falling into the manhole due to accidents during the non-working period, a grille cover needs to be arranged above the manhole. [0003] However, the conventional grille cover is fixed to the deck of the ballast tank by hook...
