Abstract

The invention relates to the technical field of ship device cooling and provides a self flow water inflow device for ship self-adaption adjusting. A flow guiding pipe, a main water conveying pipe anda fixed rotating device are included; one end of the flow guiding pipe is provided with a water inlet, and the water inlet faces the ship navigation direction; the other end of the flow guiding pipe communicates with one end of the main water conveying pipe; the fixed rotating device is connected between the outer side wall of the flow guiding pipe and a ship body of a ship; and the fixed rotatingdevice is used for guiding the flow guiding pipe to do the swinging movement along a horizontal shaft perpendicular to the ship navigation direction. According to the device, the dynamic pressure ofa water coming along with the incident flow in the ship navigation process is utilized for automatically guiding the water flow to a cooling water system in the ship body, so that it is achieved thata corresponding heat generating device is cooled, especially, due to self-adaption adjusting of the fixed rotating device, the additional resistance of the flow guiding pipe on ship navigation duringhigh-speed running of the ship is reduced, and large streaming noise is avoided.

Description

technical field [0001] The invention relates to the technical field of ship equipment cooling, in particular to a self-flowing water inlet device for self-adaptive adjustment of ships. Background technique [0002] The sea system is an important functional system for cooling ship equipment. In order to reduce the operating loss of pumps on ships and improve energy utilization efficiency, self-flow cooling technology is gradually derived. [0003] At present, the artesian cooling technology is to install an artesian water inlet device at the bottom of the ship. With the help of the dynamic pressure of the oncoming water during the ship's navigation, the water automatically flows into the cooling water system in the ship through the artesian water inlet device. Cool the corresponding heating equipment. The artesian water inlet device utilizes the ship's upstream flow pressure conversion principle to reduce the demand for the pump head of the artesian circulation. On the one ...
