Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable cabin equipment, and particularly relates to a cable cabin weather-tight hatch cover. BACKGROUND

[0002] The cable turntable of the cable laying system of a cable laying ship / wind power operation and maintenance ship is located in a cable cabin below the freeboard deck, and a cable cabin cable outlet opening is located on the main deck (the main deck is the freeboard deck). The size of the cable cabin cable outlet opening is very large. For this opening, a whole hatch cover that can be lifted away is used in the traditional design scheme, and the hatch cover is connected to a base welded on the deck by bolts. During offshore operations, the whole hatch cover is lifted away from the operation area. Since the size of the hatch cover is usually very large, the whole weight of the hatch cover is very heavy, for example, the whole weight of the hatch cover of a cable cabin cable outlet opening with a size of 9800mm*2000mm*R950mm is about 5t, so multiple people need to operate simultaneously during disassembly. Since offshore lifting is affected by the sea weather, the risk during operation is relatively large, and after the hatch cover is lifted away from the operation area, a relatively large space is needed to store and fix the hatch cover, resulting in waste of deck space. SUMMARY

[0003] In order to solve the above problems of the prior art, the present application provides a cable cabin weather-tight hatch cover, which is convenient for hatch cover operation and storage.

[0004] In order to achieve the above purpose, the main technical scheme adopted by the present application includes: a cable cabin weather-tight hatch cover, comprising a plurality of hatch cover units, a first lock buckle group and a second lock buckle group.

[0006] The present application has the beneficial effects that: the whole hatch cover in the prior art is divided into a plurality of hatch cover units, the hatch cover units are combined or disassembled in sequence during installation or disassembly of the hatch cover, the weight of each hatch cover unit is relatively small, the operation is facilitated by the ship crane, the single person can quickly complete the operation, the safety is improved. Moreover, the size of the single hatch cover unit is relatively small, and the plurality of hatch cover units can be stacked together, the occupied space is small, and the deck space is saved.

[0007] Preferably, the hatch cover units are divided into a first hatch cover, a second hatch cover and a third hatch cover from the position distribution, the first hatch cover is located in the middle, the third hatch cover is located on both sides, and the second hatch cover is located between the first hatch cover and the third hatch cover.

[0008] The first hatch cover is provided with a first recess with downward opening and a pressing plate extending outward on each side thereof, the second hatch cover is provided with a second recess with upward opening on one side thereof and a first recess with downward opening and a pressing plate extending outward on the other side thereof, and the third hatch cover is provided with a second recess with upward opening on one side thereof and a first recess with downward opening and a pressing plate extending outward on the other side thereof.

[0009] The first locking assembly is arranged on the hatch cover unit and close to the first recess, and comprises a vertical locking body and a horizontal rotating lever, the locking body is locked or unlocked by rotating, and the horizontal rotating lever is horizontally rotated along with the rotation of the locking body.

[0010] When the adjacent hatch cover units are connected together, the pressing plate of one hatch cover unit is placed on the top surface of the other hatch cover unit, the top surfaces of the two hatch cover units are located on the same horizontal plane, the outer wall of the first recess is located in the slot of the second recess, and the outer wall of the second recess is located in the slot of the first recess, and the horizontal rotating lever is rotated and abuts against the bottom of the second recess when the locking body is locked.

[0011] As described above, since the first hatch cover is provided with a first recess with downward opening and a pressing plate extending outward on each side thereof, and the second and third hatch covers are provided with a second recess with upward opening on one side thereof and a first recess with downward opening and a pressing plate extending outward on the other side thereof, when the hatch cover units are disassembled, the first hatch cover in the middle is disassembled first, and then the second and third hatch covers are disassembled in sequence, and the installation sequence is opposite. In addition, the combination and fixation or disassembly between the adjacent hatch cover units can be conveniently completed through the engagement between the first recess, the second recess, the pressing plate, the locking body and the horizontal rotating lever.

[0026] Preferably, the first groove is provided with a semicircular pipe on the groove wall close to the center of the hatch cover unit.

[0027] As described above, during the process of the second groove outer wall of one hatch cover unit falling into the groove of the first groove during the combination of the adjacent hatch cover units, the semicircular pipe on the first groove can guide the second groove outer wall, making it smoothly in place.

[0028] Preferably, the bottom of the hatch cover unit is provided with a rubber pad.

[0029] As described above, the rubber pad provided at the bottom of the hatch cover unit can play a buffering effect during the storage of the hatch cover unit.

[0030] Preferably, the second locking group comprises a butterfly nut, an articulated bolt, a pin shaft and a split pin.

[0031] The connecting part of the outer edge of the hatch cover unit and the coaming is provided with a pressing plate, the split pin is fixed on the coaming, the threaded end of the articulated bolt passes through the bottom of the pressing plate and cooperates with the butterfly nut above the pressing plate, the movable joint of the articulated bolt cooperates with the split pin, and the pin shaft can pass through the movable joint and the split pin to fix them.

[0032] As described above, through the cooperation between the pin shaft, the articulated bolt and the split pin, the detachable connection relationship between the coaming and the third hatch cover unit is realized, so that the third hatch cover unit is simple and convenient to assemble and disassemble.
