A test platform that can provide a low temperature environment

Abstract

The invention relates to a test platform capable of providing a low temperature environment, and belongs to the technical field of pool test. The test platform comprises a support, a toughened glass framework, an ice pushing device and a refrigeration system. The support is composed of an inner support and an outer support, and has the advantages including rapid installation and low cost. Use of the toughened glass provides convenience for video-recording and shooting of a test process. The ice pushing device can install U-shaped plates of different widths, lengths and heights according to different test requirements. A pneumatic set and a refrigerating set are used to provide the stable low-temperature environment for the test platform, ice thawing and change of mechanical properties canbe prevented effectively, and the ice state can approach the practical condition more. The test platform can be used for cutting and collision test of propeller and ice as well as collision test of ice and other structured objects, and water can be added into the toughened glass to make a ice-water-structured object test research, and thus, application range of the test platform is wider.

Description

technical field [0001] The invention relates to the technical field of pool tests, in particular to a test platform that can provide a low-temperature environment. Background technique [0002] In recent years, with the opening of polar routes and the development of resources, the number of ships in ice regions has increased, and the propulsion of ships in ice regions, the most important part of ships, has also attracted more and more researchers' attention. During the navigation of the ship in the ice area, a large amount of crushed ice often slides along the hull, and when it slides to the stern of the ship, due to the suction effect of the propeller, a large amount of crushed ice enters the flow field around the propeller, cutting and colliding with the propeller , has a serious impact on the propeller's hydrodynamic performance, structural strength, shafting and main engine. Therefore, it is of great significance to conduct experimental research on ice and propellers. ...

AI Technical Summary

Problems solved by technology

However, the number of ice water pond laboratories in my country is limited at present, and there is only one ice water pond in Tianjin University, which cannot fully meet the rapid development of my country's polar affairs. Therefore, it is necessary to design a low-temperature test platform to provide a stable low-temperature test environment. The interaction between propellers or structures and ice provides a low-temperature environment, making contributions to the experimental research of my country's polar equipment
