A model ice throwing and collecting device

Abstract

The invention provides a model ice putting and collecting device comprising three or more parallelly-arranged model ice putting and collecting units. Each model ice putting and collecting unit comprises a model ice sliding mechanism and a model ice collecting mechanism. The model ice sliding mechanisms comprise rotating plates (3) and steel wire ropes (9). The model ice collecting mechanisms comprise inclined plates (4), horizontal plates (6), hydraulic oil cylinders (5) and connecting rods (10). The inclined plates (4) and the horizontal plates (6) are fixedly connected to the connecting rods (10). The output ends of the hydraulic oil cylinders (5) are fixedly connected with the connecting rods (10). Cylinder seats of the hydraulic oil cylinders (5) are fixedly connected with connecting seats (13). The hydraulic oil cylinders (5) are controlled by a control box (7). The connecting rods (10) are connected with connecting plates (15) which are connected with a trailer. The model ice putting and collecting device is suitable for model ice putting and collecting during carrying-out of a ship icebreaking test in a towing tank, a deep tank and the like and has the advantages of high putting speed, good distribution uniformity, high collecting efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of ship testing, in particular to a model ice throwing and collecting device. Background technique [0002] In recent years, with the gradual warming of the global climate, the ice surface of the Arctic has gradually decreased, and the opening of the Arctic waterway has become possible. At the same time, the Arctic region is rich in natural resources and is a treasure house of human resources. It is increasingly becoming an important goal of international competition and new strategic location. The opening of Arctic routes and the development of resources will surely promote the rapid development of ships in ice regions. With the increasing demand for ships in ice regions, the experimental research of ships in ice regions has attracted more and more attention from researchers. At present, due to the limitation of the number and size of ice pools in my country, the ice-breaking navigation experiments of ship...

AI Technical Summary

Problems solved by technology

In the past test process, the experimenters often put the model ice into the pool by dumping directly on the trailer, and the whole putting process was time-consuming and laborious.

At the same time, the water splashed when the model ice hits the water surface makes the trailer, test equipment and trailer navigation track easier to rust, and brings certain damage to the test equipment

Secondly, the collection of a large amount of model ice after the test is completed is also a major problem faced by the experimenters. Nowadays, the collection of model ice is directly salvaged by the experimenters, which makes the whole experiment process a very large amount of engineering and takes a very long time.
