Description

Technical Field

[0001] The utility model relates to the technical field of ship design and construction, and in particular to a novel wave-breaking cover for a feeder container ship. Background Art

[0002] A feeder container ship is a small ship with a superstructure at the bow. In order to prevent damage to the equipment caused by large waves during navigation, a closed cover, i.e., a wave shield, is usually provided above the forecastle deck. A Chinese patent application with publication number CN102248986A discloses a method for establishing a wave shield hull frame of a ship, i.e., providing a wave shield structure at the bow of the ship.

[0003] When the ship is sailing normally, the crew needs to operate the deck machinery on the bow deck, and the lighting brightness in the operation area needs to meet the basic work needs. However, the closed wave shield structure cannot meet the lighting requirements of the crew's normal operation, so it is necessary to increase the natural lighting of the equipment operation area. The traditional way to increase natural lighting is: 1) A small hatch cover is set on the top of the wave shield. Due to the large working area, the small hatch cover will be set larger for sufficient lighting. Due to the large number of locking bolts, the opening of the small hatch cover is more complicated, and the crew has difficulty in operating it. In addition, due to the heavy weight of the small hatch cover, a small crane must be installed above the small hatch cover for easy opening; 2) A glass skylight is set on the top of the wave shield. In order to meet the lighting requirements, the glass size is large. According to the pressure requirements, the glass thickness cannot be less than 40mm. Due to the thick glass thickness, the installation is more difficult. At the same time, glass is fragile and there is a risk of multiple replacements.

[0004] Therefore, it is necessary to provide a new type of feeder container ship wave cover to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a novel wave-breaking cover for a feeder container ship to address the deficiencies in the prior art, which can meet the lighting requirements of the bow deck and greatly reduce the construction cost and shorten the construction time.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A new type of wave-breaking cover for a feeder container ship comprises a wave-breaking cover arranged above the forecastle deck, the wave-breaking cover comprises a top plate, a plurality of structural lighting holes are evenly arranged along the width direction of the top plate to form a lighting unit, a vertically arranged surrounding wall is arranged along the outer periphery of the lighting unit, the surrounding wall is fixedly connected to the top plate, the surrounding wall comprises a front wall, a rear wall and two symmetrically arranged side walls, the front wall is designed as a protruding conical structure, a forward-inclined eaves plate is arranged on the outer side of the top end of the front wall, the forward-inclined eaves plate is inclined upward, the height of the front wall is greater than the height of the rear wall, and the top surfaces of the front wall, the rear wall and the two side walls are all fixedly connected with guardrails.

[0008] Preferably, a first toggle plate is fixedly connected between the rear side of the front wall and the top plate.

[0009] Preferably, a second elbow plate is fixedly connected between the front side of the front wall and the bottom surface of the forward inclined eaves plate.

[0010] Preferably, a partition is fixedly connected between adjacent structural light-collecting holes, the front end of the partition is fixedly connected to the rear side of the front wall, and the rear end of the partition is fixedly connected to the front side of the rear wall.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. By opening multiple structural lighting holes on the wave shield, the lighting needs of the crew when operating equipment on the bow deck are met, without the need to install small hatches or transparent glass, which simplifies the structural design, reduces the difficulty of installation, shortens the construction process, and reduces the material, transportation and installation costs.

[0013] 2. In order to prevent waves from impacting deck equipment through the structural lighting holes, a surrounding wall is installed on the periphery of the lighting unit, and a forward-inclined eaves is installed on the top of the front wall to minimize the amount of water entering from the waves.

[0014] 3. Compared with the existing technology, this wave cover saves the cost of subsequent equipment maintenance or replacement, and also avoids the risk of transparent glass and other fragile items causing harm to the crew. BRIEF DESCRIPTION OF THE DRAWINGS
