Ice feeding device for cavitation water drum test

Abstract

The invention discloses an ice feeding device for a cavitation water drum test, which is characterized by comprising a cavitation water drum, a water sealing plate is erected on the upper surface of the cavitation water drum, a ship model is hung below the water sealing plate, the ice feeding device is arranged behind a ship body, the ice feeding device comprises a three-dimensional moving device used for adjusting the ice feeding position, and model ice is mounted at the tail end of the three-dimensional moving device. A propeller is installed on the ship model tail shaft and driven by a propeller motor in the ship body. The device has the advantages of being high in modularization degree, convenient to install, easy to debug, complete in function, watertight, high in precision, stable in operation and the like, the effect test of the ice water paddle ship in the cavitation bubble water cylinder can be effectively achieved, and the stability and precision of the test are improved.

Description

technical field [0001] The application relates to an ice delivery device for a cavitation water cylinder test, which belongs to the technical field of shipbuilding. Background technique [0002] When a ship sails in a polar environment, the exposed hull and propulsion device will be impacted by crushed ice, layer ice or ice floes, which puts high demands on the strength of the hull and propulsion device. Especially the propulsion device, as the power device of the ship, once there is a strength problem, it will cause irreparable losses. And to determine the ice load on the propeller and the pulsating pressure of the propeller on the bottom plate under different ice forms during the ship's voyage in the polar regions are the prerequisites for determining the strength of the propeller. When a polar ship sails in crushed ice channel, layer ice or floating ice environment, and breaks ice at the tail, the interaction between ice propellers is often very random. During the ice-wa...

Problems solved by technology

[0004] The existing ice paddle test generally does not consider the influence of the hull, and the ice paddle bench test is carried out in the air. This test method can only test and study the interaction of ice paddles in the air, and cannot simulate the actual ship during navigation. The actual function of the ice propeller is tested in the air. Under the non-decompression state, the pulsating pressure of the propeller on the bottom plate of the ship cannot be realized when the ship is sailing in the ice area.
