Description

Engine assembly for ships {A Appratus Of Engine For Ship}

The present invention relates to an engine assembly for a ship, and more particularly, by providing at least one drive shaft of a main drive unit, the main drive unit can transmit driving force to a radiator and a pump, and the drive shaft connected to the radiator transmits driving force to the pump. As it is provided to be able to deliver, it can be provided with at least one pump, it relates to a marine engine assembly that can further improve work efficiency when working using a pump.

In general, marine pump driving devices used for small fishing boats, leisure vessels, etc. use devices with very low engine output and easy overheating, such as small gasoline engines.

For this reason, there are disadvantages in that washing and spraying pressures are insufficient due to insufficient power generation, and contaminant removal is not satisfactory.

Here, when the driving device of the pump is provided with a high engine output, the loadability of the ship is reduced, and the ship's operation efficiency is very low.

In addition, fishing boats should additionally have a device for washing fishing gear such as fishing nets, and when reusing fishing nets with foreign substances attached, the fishing nets are used without removing foreign substances such as mud powder and various bacteria and meteors. However, the removal of foreign substances from fishing nets is an essential task.

Conventionally, in the case of a fishing boat among small vessels, a driving device provided to drive the fishing boat, a pump for removing foreign substances from the fishing net, and a driving device for driving the pump or a fishing net washing device are necessarily provided.

As a result, since the number of parts loaded on the ship increases, the maximum load capacity of the ship decreases, and as the weight of the ship also increases, the fuel efficiency of the ship becomes very low.

However, when a ship drive device and a fishing net washer or washing pump and a pump drive device are all provided, the efficiency of the ship is reduced, and when a pump drive device with low engine output is provided, the fishing net is not completely removed. should be reused

Therefore, in addition to the adverse effects of polluting the clean sea area, it is difficult to catch fish, which may cause a problem of lower income for fishermen. For reduction, there is a need for a device capable of improving the fuel efficiency of a ship while reducing the number of parts loaded in the ship.
