Abstract

The invention belongs to the technical field of terrain measurement, and provides an assembled seabed model elevation measurement device suitable for a small wave water tank. The device comprises a sliding rail, a cross beam, a horizontal distance measuring module and a vertical distance measuring module, wherein the horizontal distance measuring module is used for measuring the distance from a reflector, a motor mounted on the horizontal distance measuring module is used for driving the horizontal distance measuring module to move; meanwhile, the horizontal distance measuring module also plays a role in mounting the vertical distance measuring module; the sliding rail is used for installing and fixing a sliding bearing set; the vertical distance measuring module is used for placing a laser range finder and a radar scanner; and bolt supporting legs of the cross beam are used for guaranteeing that the sliding rail is always horizontal. The device can realize measurement of a physical model experiment in a small wave water tank, and effectively improves the efficiency of data measurement in the water tank experiment. The beach surface evolution, the structure action and the like under the action of waves can be evaluated through measurement data results, and necessary bases are provided for coast engineering design and construction.

Description

technical field [0001] The invention belongs to the technical field of terrain measurement and relates to an assembled seabed model elevation measuring device suitable for small wave tanks. Background technique [0002] The wave tank physical model laboratory involves the production of a fixed bed (moving bed) beach model, especially in the moving bed simulation experiment. Due to the influence of waves, ocean currents and other factors, the beach elevation is constantly changing. For the study of wave load propagation deformation on the seabed, coastal sediment movement and beach surface change, the elevation measurement of the model seabed is a very important work. Especially for the moving bed model experiment, in order to ensure that the data is accurate and sufficient, it is often necessary to select many measuring points, and to measure at regular intervals, and the positions of the measuring points should also be kept consistent. If a simple and efficient method is n...
