Technical Field
[0001] The utility model belongs to the technical field of hydrodynamic and port waterway test equipment, and particularly relates to a ball screw swing wave maker. Background Technique
[0002] In hydrodynamic and port waterway engineering experiments, wave-making tests are often required. A wave maker is one of the most important test equipment and can simulate waves in a pool or flume. There are mainly two types of wave makers: the push plate type and the 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. This type of wave maker is suitable for shallow water wave making. For deep water conditions, the waves are mainly surface waves, and there are waves only within a certain depth range on the water surface, while the lower part of the water body is minimally affected by the waves. In this case, the swing type wave maker is primarily selected. The swing type wave maker uses the swing movement of the water pushing plate around the bottom shaft to make waves. Along the water depth direction, the displacement of the surface water body is greater than that of the bottom water body. Currently, the swing type wave maker is mainly driven by a synchronous belt, but this type of swing type wave maker has technical problems such as small driving force, low precision, and short service life of the drive belt. Therefore, a ball screw swing wave maker with high precision, high reliability, strong stability, and long service life is needed. Content of the Utility Model
