Description

Double-sided opening and closing watertight connection structure

Technical Field

The utility model relates to a watertight deck (bulkhead) open-ended manhole cover, more specifically say, relate to a two-sided watertight connection structure that can open and close.

Background

The manhole cover is a common opening and closing device for a watertight cabin entrance and exit on a ship, is generally installed on a manhole, and is a general name of a cover plate with sealing performance and fixed accessories thereof. Manhole covers can be classified as either protruding (as shown in figure 1) or flush (as shown in figure 2) depending on whether the cover is installed above the surface of the opening. Traditional manhole cover is the single face mode of opening and close, and bedplate 2 and face 5 direct weld of deck adopt the sealing strip to seal between apron 1 and the bedplate 2 bedplate, realize sealedly under fastener 4 effect. When the cover plate is opened, the fastener 4 is firstly unscrewed, and then the cover plate 1 can be taken down, so that single-side opening is realized.

The structure shows that the traditional manhole cover is opened and closed from the outer side of the cabin, and if the manhole cover is in a closed state, the manhole cover cannot be opened and closed from the inner side of the cover plate 1, namely cannot be opened from the cabin by self.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect that exists among the prior art, the utility model aims at providing a watertight connection structure can be opened and close to two-sided, crosses the cab apron through addding the centre, can realize the two-sided of manhole cover and open and close, satisfies the needs that special conditions came in and go out.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a double-sided openable watertight connecting structure is connected to a deck surface and comprises a seat plate connected to the deck surface, wherein a transition plate and a cover plate are sequentially connected to the seat plate;

sealing strips are arranged on the contact surface between the seat plate and the transition plate and the contact surface between the transition plate and the cover plate;

the seat plate is connected with the transition plate through a first fastener, and the transition plate is connected with the cover plate through a second fastener.

The seat board is welded on the deck surface.

In the technical scheme, the utility model provides a watertight connection structure can be opened and close to two-sided, still has the beneficial effect of following several points:

1) the connecting structure of the utility model can realize the double-sided opening and closing of the manhole cover and the single-sided opening and closing of the outer part of the transmission manhole cover, and can meet the requirements of coming in and going out of some special places;

2) the utility model discloses connection structure simple structure, reliable, low in cost easily makes the realization.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Please refer to fig. 3 to 4, the present invention provides a double-sided openable watertight connection structure, which is connected to a deck surface 6, and comprises a seat plate 7 connected to the deck surface 6, the seat plate 7 is directly welded to the deck surface 6, and the seat plate 7 is sequentially connected to a transition plate 8 and a cover plate 9.

Preferably, sealing strips 10 are added on the contact surface between the seat plate 7 and the transition plate 8 and the contact surface between the transition plate 8 and the cover plate 9 for sealing.

Preferably, the seat plate 7 is connected with the transition plate 8 through a first fastener 11, and the transition plate 8 is connected with the cover plate 9 through a second fastener 12. The seat plate 7 and the transition plate 8 and the cover plate 9 are connected and fastened under the action of a first fastener 11 and a second fastener 12 respectively, and gap sealing is realized through a sealing strip 10.

Through the utility model discloses connected mode realizes that the manhole cover is outside to be opened, unscrews second fastener 12 on the apron 9, can take off apron 9, realizes the outside and opens. Through the utility model discloses connected mode realizes that the manhole cover is inside to be opened, unscrews first fastener 11 on the bedplate 7, can take off apron 9 and cross cab apron 8, realizes inside opening.

To sum up, the utility model discloses connected mode contrast tradition mode of opening and close owing to newly increased cab apron 8, sealing strip 10 divide into about two rings, respectively with cross and realize watertight fixed connection between the cab apron 8. The cover plate 9 can be taken down by unscrewing the second fastener 12 to realize external opening, and the cover plate 9 and the transition plate 8 can be taken down by unscrewing the first fastener 11 to realize internal opening.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
