Abstract
The invention relates to a water and cargo accumulation preventing structure for a shipborne manhole cover. The water and cargo accumulation preventing structure comprises a cargo hold bottom (1), the embedded manhole cover (2) and a protective cover plate (3), a steel protective ring (4) is fixedly arranged along a vertical wall plate (1a) of the cargo hold bottom, the top end of the protective ring makes contact with the lower edge of the protective cover plate, and the thickness of the steel protective ring is larger than the width of the gap between the cargo hold bottom and the protective cover plate. A groove (4a) is formed in the side, facing the protective cover plate, of the steel protective ring, and a rubber strip (5) is clamped in the groove. The groove is formed in the upper end of the side face of the steel protective ring. As the steel protective ring and the rubber strip are arranged, cargos and water can be effectively prevented from accumulating between the manhole cover and the cargo hold bottom and swept by staff conveniently, and corrosion to the manhole cover by the cargos and the water is reduced.
Description
Technical field
The present invention relates to the anti-ponding of manhole cover for ship and amass goods structure, be applied in lead to cargo tank and ballast tank bottom bulge carrier and multi purpose ship manhole cover on.
Background technology
Bulge carrier and multi purpose ship, cargo compartment can load bulk freight, such as: coal, iron ore, cereal etc.Loading adopts the modes such as belt conveyor, and general grab bucket and the forklift of adopting of unloading combines.In order to ensure the normal operation of forklift, tank top requires smooth, can not have raised structures, so the manhole of the ballast chamber/cargo tank of tank top need adopt sunk manhole cover.Each large shipyard all applies standard C B/T4392-2014, CC/CD type sunk manhole cover manhole cover for ship (CC: flush type ellipsoid, CD: flush type is oval).As shown in Figure 6, adopt after holding tiny bulk freight in the cargo hold of this sunk manhole cover, between cover sheet and hull structure, easy ponding and long-pending goods, add the difficulty of sweeping, waste time and energy, and also causes the corrosion of manhole cover.
Summary of the invention
Technical matters to be solved by this invention is to provide the anti-ponding of a kind of manhole cover for ship to amass goods structure, effectively can reduce water and the accumulation of goods between manhole cover and tank top.
In order to solve the problem, the technical solution used in the present invention is as follows:
The anti-ponding of a kind of manhole cover for ship amasss goods structure, and the cover sheet comprising tank top, sunk manhole cover and be positioned at above sunk manhole cover, is characterized in that:
Be installed with back up ring along on the vertical wallboard of described tank top, the top of described back up ring contacts with the lower edge of cover sheet, and the thickness of back up ring is greater than the gap width between tank top and cover sheet.
Further improvement is, described back up ring is provided with groove towards the side of cover sheet, is equipped with rubber strip in described groove.
Further, described groove is arranged on the upper end of side, back up ring.
Described back up ring is preferably made up of steel.
Compared with prior art, beneficial effect of the present invention is:
The present invention has welded steel back up ring on vertical wallboard; groove is offered inside back up ring; and in groove, rubber strip is installed; gap between tank top and cover sheet is blocked by steel back up ring; when contacting with rubber strip after cover sheet locking; produce distortion after rubber strip is under pressure, fit with cover sheet surrounding, serve the effect of anti-ponding, anti-long-pending goods.Utilize this device, effectively can prevent ponding and long-pending goods, decrease the difficulty of sweeping, and effectively prevent goods, ponding to the corrosion of manhole cover.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail; the restriction of described embodiment not to invention protection domain; obviously, those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection scope of the present invention.
Shown in composition graphs 1 to Fig. 3; the anti-ponding of a kind of manhole cover for ship amasss goods structure; the cover sheet 3 comprising tank top 1, sunk manhole cover 2 and be positioned at above sunk manhole cover; back up ring 4 is installed with along on the vertical wallboard 1a of described tank top; the top of described back up ring contacts with the lower edge of cover sheet, and the thickness of back up ring is greater than the gap width between tank top and cover sheet.Utilize the setting of back up ring, can effectively prevent goods from entering between tank top and cover sheet, described back up ring is made up of steel.Described back up ring is provided with groove 4a towards the side of cover sheet, and described groove is preferably arranged on the upper end of side, back up ring.Rubber strip 5 is equipped with in described groove.As shown in Figure 4 and Figure 5, the setting of rubber strip better can play sealing function, prevents goods from entering, and is more conducive to the infiltration of water.
The present invention effectively can prevent ponding and long-pending goods, decreases the difficulty of sweeping, and effectively prevent goods, ponding to the corrosion of manhole cover.
Claims (4)
