Water injection type multi-module push plate wave maker

Abstract

The invention discloses a water injection type multi-module push plate wave maker, belongs to the technical field of experimental equipment of ocean geotechnical engineering, and aims at solving the problems that a wave maker is in sufficient in power, long in wave making period, narrow in amplitude and easy to generate clutters. The wave maker is composed of a water tank, servo motors, a wave making plate, a water injection pipe, a filtering net and a wave making film; the water tank, the filtering net and the wave making film form an enclosed water area; the servo motors drive a structural support and the wave making plate to make reciprocating motion via a driving rod so as to form initial waves; the wave making plate composed of eight modules, and the modules are driven by different servo motors to make waves in different frequencies; the water injection pipe is controlled by a computer, and water whose amount is calculated in advance is injected along the wave making plate; the filtering net turns waves which are spread in the inclined direction under effect of a flow deflector; and the wave making film is supported by a steel skeleton which moves along a track, and used to merge waves and eliminate clutters. The wave making precision is improved, and the engineering practicality is high.

Description

technical field [0001] The invention belongs to the technical field of marine geotechnical engineering experimental equipment, in particular to a wave maker, in particular to a water-injection multi-module push plate wave maker. Background technique [0002] Wave generator is a kind of experimental equipment widely used in marine geotechnical engineering. Its function is to create waves of different wavelengths and wave heights in the laboratory, simulating the impact of actual waves on marine pile foundations, docks, etc. Although the current single-plate wave generator has a simple structure and is easy to control, because it relies on a single servo motor to drive the entire wave-making plate to perform a single reciprocating motion, the power of the servo motor is insufficient and the practical application range is limited; when the wave-making plate moves back and forth During the movement, a short-lived cavity will be formed on the contact surface between the wave-mak...

Although the current single-plate wave generator has a simple structure and is easy to control, because it relies on a single servo motor to drive the entire wave-making plate to perform a single reciprocating motion, the power of the servo motor is insufficient and the practical application range is limited; when the wave-making plate moves back and forth During the movement, a short-lived cavity will be formed on the contact surface between the wave-making plate and the water, making the wave-making period long and prone to clutter and other problems
