Embodiment 1

[0030] A single fulcrum ultra-wide through-flow swing type wave maker, see attached figure 1 , which includes a servo motor 1, the servo motor is connected with the electric cylinder 2, the electric cylinder converts the rotary motion of the servo motor into a linear motion, the end of the action push rod 3 of the electric cylinder is hinged with one end of a connecting rod 4, and the connecting rod 4 The other end is hinged with one end of a swing rod 6, and the other end of the swing rod 6 is hinged with the wave-making plate bracket 7. One point of the rod body of the connecting rod 4 is hinged on one side of the frame body 11 through the bracket 5, and the electric cylinder 2 The cylinder is provided with a rotating shaft 10, and the rotating shaft 10 of the electric cylinder is rotatably fixed on the top of the frame body 11 through a column 12.

[0031] The wave-making plate support 7 is triangular, and the wave-making plate support 7 is vertically arranged. The whole wa...

Embodiment 2

[0036] During the installation process of the wave maker, it is necessary to adjust the horizontal angle of the electric cylinder and the action push rod to ensure that the electric cylinder, action push rod and connecting rod of the wave maker are on the same plane. In order to install the wave maker conveniently, ensure that the electric cylinder, action push rod and connecting rod of the wave maker are on the same plane. Figure 4 In this embodiment, on the basis of Embodiment 1, the rotating shaft 10 of the electric cylinder is fixed on the top of the frame body 11 through the rotating device 9; see the attached Figure 5, the rotating device 9 includes a vertical rotating shaft 9-1, a lower base 9-2, an upper base 9-3 and a connecting plate 9-4, the rotating shaft 9-1 is vertically rotatably arranged in the lower base, The lower base 9-2 is fixed on the top of the frame body 11 by bolts, the upper base 9-3 is coaxially fixed and set on the rotating shaft 9-1 (welding and ...

Abstract

The invention discloses a single fulcrum ultra-wide permeable oscillating wave making machine comprising a servo motor connected with an electric cylinder. A terminal of the action push rod of the electric cylinder is hinged onto one end of a connecting rod, the other end of the connecting rod is hinged onto one end of an oscillating rod, the other end of the oscillating rod is hinged onto a wave making plate bracket, and one point of a rod body of the connecting rod is hinged on one side of a bracket body through the bracket; a cylinder tube of the electric cylinder is provided with a rotating shaft; the rotating shaft of the electric cylinder is rotatably fixed on a top end of the bracket body. The wave making machine disclosed in the invention is driven via a single fulcrum; the wave making machine is small in driver element quantity and low in production cost; the wave making machine is driven by the servo motor and high in driving force and reliability; a lever principle is used, the oscillating rod is used for amplifying the movement of a driver into movement of a wave plate; driver stroke is effectively used, and wave making ability is improved.

Description

technical field [0001] The invention belongs to laboratory test equipment for port waterway engineering, in particular to a single fulcrum ultra-wide through-flow swing type wave maker. Background technique [0002] In the port waterway engineering laboratory, wave-making tests are often required. The wave-making machine is the most important test equipment, which can simulate waves in pools and tanks. There are mainly two types of wave making machines: push plate type and swing type. The push plate type wave maker uses the horizontal movement of the push plate to push the water body to form waves. Along the water depth direction, the movement speed and displacement of the water body in front of the plate are the same. Create waves in shallow water. For deep water conditions, the waves are mainly surface waves, and waves only exist within a certain depth range on the water surface, and the lower part of the water body is minimally affected by waves. In this case, a swinging...
