Example 2

The difference between this embodiment and embodiment 1 is that in this embodiment, the automatic hatch cover opening and closing device 7 is designed for the hatch cover 6 (corresponding to a part of the deck at the front end of the superstructure) to realize the opening and closing operation of the hatch cover, so this design is mainly performed because when the reversible hatch cover and the springboard 1 is rotated downwards and opened to connect the boat and the beach head, the personnel on the boat deck or in the superstructure, such as directly jumping from the boat bow to the springboard, has a large potential safety hazard, and also causes a large gravity load on the springboard, which not only damages the service life of the springboard, but also seriously causes the breaking of the springboard, which will directly affect the normal use of the boat, so the safest way is that the personnel or objects on the deck enter the cabin at the lower part of the deck and then directly walk up the springboard from the cabin to finish the landing.

In order to achieve the purpose, the embodiment is modified in a targeted manner, in which the related electrical control elements are electrically connected with a main controller, specifically, the hatch 6 is divided into two parts, namely a left hatch 61 and a right hatch 62, the outer ends of the left hatch 61 and the right hatch 62 are respectively hinged with the hull through hinges, the inner ends of the left hatch 61 and the right hatch 62 are respectively provided with a first fastening hole 611 and a second fastening hole 621, the first fastening hole 611 and the second fastening hole 621 are respectively identical in structure but reversed in position, in a closed state, the first fastening hole 611 and the second fastening hole 621 on the left hatch 61 and the right hatch 62 are closed in an engaged manner, a set of hatch automatic opening and closing devices 7 are respectively arranged at the bottoms of the left hatch 61 and the right hatch 62, the hatch automatic opening and closing devices 7 comprise a mounting bracket 71 and a hatch opening and closing push rod 72, the mounting bracket 71 is fixed on the hull, one end of the hatch cover opening and closing push rod 72 is movably connected with the bottom of the left hatch cover 61/the right hatch cover 62, the other end of the hatch cover opening and closing push rod is movably connected with the mounting bracket 71 on the corresponding side, a motor and a reduction gear are arranged in the hatch cover opening and closing push rod 72, the reduction gear can carry different reduction ratios to amplify thrust according to different loads, and therefore position transition of the hatch cover from a horizontal state to a vertical state is achieved in an auxiliary mode.

When the hatch cover 6 needs to be opened, related personnel move back to the unmodified deck part on the ship or enter an upper-layer building, then the main controller controls the hatch cover opening and closing push rod 72 to drive the hatch cover 6 to turn over towards two sides, after the hatch cover opening and closing push rod 72 finishes specified positioning movement, the left/right hatch covers are completely opened, and the hatch cover opening and closing push rod 72 stops running.

The hatch cover 6 mainly comprises a bottom cover plate 63, a top closing plate 64 and a rib plate 65, in order to improve the stability of the hatch cover 6 in the opening and closing process and avoid the safety problem caused by the accidental opening of the hatch cover 6, a hatch cover automatic locking device 8 is arranged at the middle section position in the hatch cover 6 (the automatic locking device can be provided with a plurality of groups, and the automatic locking device can be adaptively selected according to the length, weight, pushing difficulty and the like of the hatch cover 6), the hatch cover automatic locking device 8 comprises an installation column 81, a hatch cover lock push rod 82, an inserted latch 83 and a limiting block 84, the hatch cover lock push rod 82 is fixed in the right hatch cover 62 through the installation column 81, the end part of a movable rod of the hatch cover lock push rod 82 is connected with the inserted latch 83, the outer side end of the inserted latch 83 is in an oblique wedge shape, the limiting block 84 is arranged at the outer side of a first fastening hole 611, the bottom of the limiting block 84 is in an oblique wedge shape matched with the end part of the inserted latch 83, in the initial state, the inserted latch 83 is in an oblique wedge shape matched with the limiting block 84, the right hatch 62 is fixed in position.

On the premise of arranging the automatic cabin cover locking device 8, when the cabin cover 6 is required to be opened, the cabin cover 6 needs to be unlocked before the cabin cover opening and closing push rod 72 is started, specifically, the main controller controls the cabin cover lock push rod 82 to retract, and then drives the latch 83 and the limiting block 84 to be separated from the wedge-matched state, so that the cabin cover 6 is unlocked, and the cabin cover lock push rod 82 stops running after the specified positioning movement is completed.

The utility model discloses a cabin cover, including left and right cabin cover, the bottom of right cabin cover, preceding, the back both ends correspond respectively and are equipped with a set of bearing structure 9, every group bearing structure 9 includes flexible bracing piece 91, hinged end 92 and stiff end 93, hinged end 92 is fixed on the hull, the inboard bottom at left cabin cover 61 right cabin cover 62 is established to stiff end 93, the one end and the hinged end 92 swing joint of flexible bracing piece 91, the other end and stiff end 93 swing joint, bearing structure 9 mainly plays the effect of auxiliary stay when cabin cover 6 is closed, help cabin cover 6 to bear stably not flagging when gravity.
