The invention discloses an embedded grating cover which comprises a cover plate, two fixing modules and a connecting plate. The cover plate is arranged on a deck of a ballast tank and used for covering a manhole formed in the deck. The two fixing modules are arranged on one side of the cover plate in an interval, each fixing module comprises a fixing plate, and one end of the fixing plate is fixedly connected with the deck. One end of the connecting plate is in pivoted connection with the other end of the fixing plate, and the other end of the connecting plate is fixed to one side of the cover plate. The embedded grating cover facilitates uncovering or covering of the cover plate, facilitates cover plate opening when a maintainer needs to enter the ballast tank for maintenance, meanwhile the cover plate blocks the manhole formed in the deck in a non-working period, the danger than a worker accidentally falls into the manhole is avoided, and safety is improved. In addition, the cover plate and the deck can be connected firmly, the reliability is higher, and the cover plate has anti-slip effect and can prevent the worker from wrestling due to sliding.
