Hatch structure preventing ponding

Abstract

The invention relates to the technical field of hull manufacturing, in particular to a hatch structure preventing ponding. The hatch structure is provided with a deck. The deck is provided with a hatch used for communicating with the inside of a cabin. The hatch structure is characterized in that the part, around the hatch, of the deck is provided with a groove used for holding a hatch cover. A water guide table of which the side face is triangular is arranged in the groove. The highest point of the triangular water guide table is lower than the depth of the groove. The hatch cover is arranged above the groove. A hatch cover enclosure bulkhead matched with the triangular water guide table is arranged around the hatch cover. A lifting handle is arranged behind the hatch cover. The part, of the lowest point adjacent to the triangular water guide table, of the deck is provided with a water guide hole connected with a ponding tank through a water guide pipe. The hatch structure has the advantages of being stable in structure, capable of saving space, preventing wind, ponding and lifting and the like.

Description

technical field [0001] The invention relates to the technical field of ship hull manufacturing, in particular to a hatch structure with stable structure, space saving, windproof and stagnant water. Background technique [0002] As we all know, as our country actively promotes the development of FRP fishing vessels, fishing vessels often have waves turning over the deck during navigation or operation, causing the hatch coaming cover to shift or lose, and seawater will also seep into the deck In the hatch provided on the deck, in order to prevent the displacement or loss of the hatch coaming cover and prevent water seepage in the hatch, people set a hatch coaming higher than the deck around the hatch on the deck, and the opening above the hatch coaming There is a hatch cover, so since the hatch cover is higher than the deck, artificially lifting it from the middle of the hatch cover will increase the labor intensity of people. In order to reduce the labor intensity of the staf...

[0002] As we all know, as our country actively promotes the development of FRP fishing vessels, fishing vessels often have waves turning over the deck during navigation or operation, causing the hatch coaming cover to shift or lose, and seawater will also seep into the deck In the hatch provided on the deck, in order to prevent the displacement or loss of the hatch coaming cover and prevent water seepage in the hatch, people set a hatch coaming higher than the deck around the hatch on the deck, and the opening above the hatch coaming There is a hatch cover, so since the hatch cover is higher than the deck, artificially lifting it from the middle of the hatch cover will increase the labor intensity of people. In order to reduce the labor intensity of the staff, a hatch cover device that can be opened and closed automatically has been developed. The device often adopts hydraulic opening and closing and hydraulic locking, which reduces the labor intensity of the staff. However, the hydraulic source pipeline system equipped with it is complicated, and oil leakage accidents often occur in the hydraulic system, which may easily cause the opening and closing and locking mechanism to fail. Normal work, poor system reliability, oil leakage is likely to cause environmental pollution and fish pollution
