Abstract

The invention discloses a pushing and flapping combined type wave generator mainly comprising components such as a guide rail support, a wave generation plate mechanism, a lead screw and nut mechanism, a switching snap joint, a rear seat, a second servo motor, a driving wheel, a driven wheel, a coupler, a first servo motor, a bearing, a guide rail support boss, a guide rail support main body, a guide rail support frame, a bolt hole, a guide rail, a first guiding groove, a first lead screw hole, a second lead screw hole, a guide rail support frame inner end face, a wave generation plate, a support seat, a wave generation frame and a rotation shaft. According to the pushing and flapping combined type wave generator provided by the invention, pushing and flapping movements of the wave generation plate can be achieved via a set of lead screw and nut transmission mechanism; the switching between two movement modes of pushing and flapping can be automatically, quickly and accurately completed via the switching snap joint; waveform features of waves generated by pushing and flapping are different, so that the waveforms more accordant with experiment requirements can be generated via a pushing-flapping-pushing combined wave generation mode, a flapping-pushing-flapping combined wave generation mode, a pushing-flapping-flapping combined wave generation mode or a flapping-pushing-pushingcombined wave generation mode.

Description

technical field [0001] The invention relates to the field of ocean engineering and experimental research of ports and offshore engineering, in particular to a push-rock combined wave maker. Background technique [0002] In the field of marine engineering and port and offshore engineering experimental research, due to geographical factors and the complexity and uncertainty of the marine environment, outdoor field experiments often have certain risks. Researchers usually use laboratory flume wave-making technology to simulate ocean waves. Wave simulation is an important experimental method, and wave-making machines are necessary experimental devices for flume experiments. According to the different motion forms of the wave-making plate, it can be divided into push plate type and rocking plate type wave maker. The push-plate wave maker realizes the simulation of waves by pushing the wave-making plate along the horizontal direction; the rocking-plate wave maker realizes the wav...

Problems solved by technology

Due to the different wave-making principles, the push plate type and the rocking plate wave machine have their own characteristics. They are used in different experimental environments. The push plate wave machine is suitable for shallow waters, and the rocking plate wave machine is suitable for deep waters. , due to the complexity and diversity of the experimental requirements, when different waves are required in the experiment, the wave maker with a single motion form can no longer meet the requirements, and the method of replacing the wave maker can only be adopted, which increases the cost of the experiment

However, the existing push-swing combined wave generators at this stage require manual switching during the switching process of horizontal push and swing working modes, which reduces the experimental efficiency.
