Hatch cover of engine room of trail suction dredger

Abstract

The invention relates to a hatch cover of an engine room of a trail suction dredger, and belongs to the technical field of engineering vessel equipment. The hatch cover of the engine room of the trail suction dredger is characterized by being composed of a large engine room hatch cover and small engine room hatch covers, 2-6 small engine room hatch covers are arranged on the large engine room hatch cover in an inclined mode, and therefore the through-flow area is easily increased. Gas circulation is effectively increased, it is avoided that heat dissipation is poor, and heat accumulates inside the engine room, the environment of the engine room is improved, the failure rate of the equipment is greatly decreased, and the construction efficiency of the trail suction dredger is obviously improved; the hatch cover has the advantages of being simple in structure, convenient to operate, economical, practical, environmentally friendly, high in construction efficiency, wide in application range and capable of being partially opened even in rainy days.

Description

technical field [0001] The invention belongs to the technical field of engineering ship equipment, in particular to an engine room hatch cover of a drag suction ship. Background technique [0002] At present, with the development of large-scale and automatic ships, the equipment in the engine room is becoming more and more complex and diverse. The Sky Whale is particularly prominent in this aspect, and due to the hull structure, the equipment in the engine room is compactly arranged, and the ceiling height of the engine room is too low, resulting in a relatively high temperature in the engine room, and the heat cannot be dissipated well. In addition, there are 6 fans in the engine room, and these six fans are used for air supply, which makes the air circulation poor and the heat cannot be dissipated. The ship is constructed in the South China Sea, and the local hot and humid climate conditions make the heat dissipation problem inside the engine room more prominent. Excessiv...

AI Technical Summary

Problems solved by technology

The Sky Whale is particularly prominent in this aspect, and due to the hull structure, the equipment in the engine room is compactly arranged, and the ceiling height of the engine room is too low, resulting in a relatively high temperature in the engine room, and the heat cannot be dissipated well.

In addition, there are 6 fans in the engine room, and these six fans are used for air supply, which makes the air circulation poor and the heat cannot be dissipated. The ship is constructed in the South China Sea, and the local hot and humid climate conditions make the heat dissipation problem inside the engine room more prominent.

Excessive ambient temperature is a great threat to the normal operation of machinery and equipment. There are a series of problems such as a significant increase in the failure rate of equipment, which seriously affects the service life of the equipment, significantly reduces construction efficiency, and increases construction costs.
