Following lifting type wave absorbing device

Abstract

The invention provides a follow-up lifting type wave absorbing device which comprises lifting devices fixed on a trailer, a lifting wave absorbing plate which is arranged in the middle of the lifting devices and has a wave absorbing function, wave absorbing holes which are formed in the wave absorbing plate in sequence, and a replaceable wave absorbing filter element which is inserted into the wave absorbing plate, and each lifting device further comprises a fixing device fixed on the trailer. The trailer supplies power to the built-in motor, the motor is connected with the lead screw and controls the lead screw to rotate, and a terminator is arranged at the bottom of the lifting device and used for controlling the terminating point of the wave absorbing plate. According to the invention, targeted wave absorption is carried out according to three parts formed by waves; the pool wall is not damaged, and the test precision and wave generation are not influenced; depending on the pool trailer, an independent power supply device is not needed, and other auxiliary devices are not needed; the device is high in flexibility, detachable and suitable for all pools with trailers; and the filter element can be replaced, the efficiency is high, and the service life is long.

Description

technical field [0001] The invention relates to a wave-eliminating device, in particular to a follow-up lifting type wave-eliminating device, which belongs to the technical field of ship model testing. Background technique [0002] The ship model towing pool is a test facility that uses various aircraft models to conduct experiments to understand the movement attitude, speed, propeller power and other aircraft performance of ships, torpedoes, and submarines. Ship models (or other aircraft Model) is dragged by a trailer above the pool to move forward or backward. When large-scale, high-speed model tests are carried out in the towed pool and artificial wave generation is required, each time a test of a working condition is completed, it is necessary to wait for the water surface with large amplitude to return to calm until it meets the requirements of the test before proceeding. A working condition test. The use time of the towed pool test is precious. From the perspective o...
