Abstract

The invention discloses a full circle swinging tugboat with outboard cooling, which comprises a body, a superstructure arranged on the upper side of the body, and a full circle swinging propeller located below a stern, wherein a cooling water system is arranged outboard a body, the cooling water system comprises multiple seawater boxes arranged below a freeboard of the body, and outboard coolers respectively fixed in each seawater box and soaked in the seawater, multiple outboard coolers are connected with multiple stop valves in series in sequence through pipelines, a high-temperature outlet of cooling freshwater of a marine main engine cooler is communicated with cooling freshwater input ports of the outboard coolers, and cooling freshwater output ports of the outboard coolers are communicated with a low-temperature inlet of the cooling freshwater of the marine main engine cooler. According to the invention, the circulating cooling freshwater of a marine main engine is fully cooled by directly utilizing outboard seawater, power consumption for operation of a special seawater cooling water pump and a seawater cooling water pump is saved, pipelines and fittings are simplified, and the ship device cost and the operation cost are reduced.

Description

technical field [0001] The invention relates to an engineering ship, in particular to a full-turn tugboat in which the circulating cooling fresh water of the main engine of the ship is directly cooled by seawater outboard, and belongs to the technical field of ship engineering. Background technique [0002] The full-turn port tugboat has the characteristics of flexible operation and the ability to move the ship in any direction. It is widely used in the north and south ports to assist large ships in docking and leaving the port, fire fighting, piloting and other operations. In order to ensure the normal operation of the main engine of the ship, the main engine of the ship is equipped with a cooling system. This cooling system generally uses seawater pumps to absorb seawater outside the ship through the seawater tank of the ship, and cools the high-temperature circulating fresh water in the cooler of the main engine of the ship. The low-temperature circulating fresh water co...
