Problems solved by technology

In the prior art, due to the influence of the slope-type side wave breakers arranged longitudinally on the side wall of the towing pool, the side wall of the simulated ice area laid cannot form an effective vertical wall channel, resulting in a large error with the simulated environment of the test. The results of the mold ice breaking load test have a great influence

Embodiment Construction

[0028] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] like figure 1 and figure 2 As shown in the figure, a liftable floating ice channel for the dragging pool test of the present embodiment includes a pool wall 1 arranged oppositely, a drag pool is arranged in the pool wall 1, and the opposite inner sides of the pool walls 1 on both sides are arranged at intervals. The floating ice baffles 3 along the length direction, the floating ice baffles 3 are located at the height of the water surface 4 of the towing pool, and the area between the two floating ice baffles 3 constitutes the floating ice channel; A lifting mechanism 5 is installed, and the lifting mechanism 5 drives the floating ice baffle 3 to move up and away from the water surface 4; the side of the pool wall 1 located on the outside of the floating ice baffle 3 is installed with a wave breaking plate 2 along the length direction; A flo...

Abstract

The invention relates to a liftable floating ice channel for a towing tank test. The channel comprises oppositely arranged tank walls, a towing tank is arranged in the tank walls, floating ice bafflesare arranged on the inner sides of the tank walls at intervals along a length direction, the floating ice baffles are positioned at a height of a water surface, and an area between the two floating ice baffles forms a floating ice channel; lifting mechanisms are installed on the two floating ice baffles respectively and drive the floating ice baffles to move upwards to leave the water surface; and a wave absorbing plate in the length direction is mounted on the side surface of the tank wall on the outer side of each floating ice baffle. The floating ice channel is formed by arranging the floating ice baffles in the towing tank, simulated floating ice with different density sets is distributed, and a ship model is towed to sail under the driving of a towing trailer of the towing tank so that an ice load test is carried out; when a rapid still water test is carried out, only the floating ice baffles need to be lifted to be separated from the water surface through the lifting mechanism;and in the invention, test functions of the towing tank are diversified, a utilization rate and test efficiency of the towing tank are greatly improved, operation is convenient, and comprehensive performance is good.

Description

technical field [0001] The invention relates to the technical field of ship model ice load test equipment, in particular to a liftable floating ice channel used for towing pool tests. Background technique [0002] The towing tank is the basic equipment for ship rapidity test research, supplemented by a trailer tow the ship model in a straight line at a uniform speed relative to the tank, and the hydrodynamic coefficient acting on the ship model can be measured; usually, it is arranged longitudinally on the water surface of the side wall of the towing tank. Slope-type edge wave absorber is used to absorb water surface waves generated by the ship model during the still water test operation. [0003] With the development of science and technology and shipping activities in polar ice areas, the research on ice-breaking navigation performance of ships in ice areas has become increasingly in-depth. With the help of the towing pool, simulated ice cubes with different distribution ...
