Trailer device used on testing water pool

Abstract

The invention belongs to the technical field of marine engineering testing, and relates to a trailer device used on a testing water pool. The trailer device comprises a four-degree-of-freedom workingbridge, a main trailer track, a subsidiary trailer track and a safety protection system. The four-degree-of-freedom working bridge in the trailer device adopts a full truss structure, the situation that a vortex zone is formed when the upper and lower wind speeds are different since the front resistance of the structure to a wind field is too large is avoided, the accuracy of a measurement resultis improved accordingly, the wind resistance is reduced, the testing energy consumption is also reduced, and the testing cost is reduced. The trailer device adopts the safety protection system, and the safety and reliability of the trailer device are also ensured while the cost is reduced. The trailer device has the main advantages that the overall device is simple in structure, easy to install, convenient to operate, safe and reliable, the accuracy of the measurement result can be improved, and the cost can also be reduced.

Description

technical field [0001] The invention relates to a trailer device used on a test pool, belonging to the technical field of marine engineering tests. Background technique [0002] In marine development, structures such as ships and offshore platforms must withstand the test of harsh environments, including the combined effects of complex environmental factors such as wind, waves, and currents. The complex and changeable marine environment and the lack of relevant engineering experience make ships and offshore platforms Ocean engineering research needs to rely more on model tests. Physical model tests are the basis for ship and ocean engineering construction. Obviously, without test tanks, effective physical model tests cannot be carried out, and the construction and development of my country's ship and ocean engineering cannot be discussed. From the beginning, the construction of the test pool, in addition to building a pool body of a certain scale, also needs to be equipped wit...

Problems solved by technology

[0003] With the development of social economy and the advancement of science and technology, the individual requirements for trailer devices are becoming more and more intense. For example, a ship and ocean engineering test pool has the following characteristics: (1) The overall wind-making system-wind tunnel is above the pool, The space height of the test area is narrow (less than 5m), and the requirements for the height of the trailer are relatively strict; (2) If a conventional box girder structure or a box girder and truss hybrid structure is adopted, the upper and lower wind speeds will be caused by the excessive resistance of the structure to the front of the wind field. At the same time, the larger wind resistance will greatly increase the energy consumption of the test and increase the cost; (3) the span is large (30-50m), the trailer must ensure a certain Rigidity; (4) The trailer speed is low, the highest speed is 2-3m / s, and the lowest speed is 0.05m / s
