Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] In the method of the invention, the height-adjustable horizontal blade is used to flatten the sand bed, and at the same time, a horizontal laser is used to position and calibrate the flatness of the sand bed, thereby obtaining a flat sand bed surface with high consistency. To realize this method, the present invention uses such as figure 1 and figure 2 The shown experimental flume sediment bed surface leveling system, the composition, setting method and use of the system will be described respectively below in conjunction with the accompanying drawings.

[0024] First, the main structure of the system of the present invention includes an "I" shaped blade 3, a rubber sheet 5, a level 4, a laser 13, a roller 10, a vertical connecting rod 8, a horizontal connecting rod 9 and a horizontal tie rod 2.

[0025] Wherein, "work" shape blade 3...

Abstract

The invention discloses an experimental water tank sediment bed surface leveling method and an experimental water tank sediment bed surface leveling device. The experimental water tank sediment bed surface leveling device at least comprises a glass water tank (6) filled with sediments and water, a laser (13) arranged at the outer side of one end of the glass water tank (6), a horizontal I-shaped blade (3) with adjustable height, arranged in the glass water tank (6) and a level gauge (4) connected with the horizontal I-shaped blade (3). According to the method, the horizontal I-shaped blade with adjustable height is used to level the sediment bed, and level laser is used for locating and calibrating the flatness of the sediment bed, and therefore, a flat sediment bed surface having high consistency can be acquired. According to the device and the method, the water level of the sediment bed can be precisely determined, and the error range of the flatness of the sediment bed can be controlled to be up to 1mm; and besides, the horizontal I-shaped blades having different widths can be produced according to different water tank widths, and thus have wide applicability to the experimental water tank.

Description

technical field [0001] The invention relates to the technical field of leveling the sediment bed surface of test tanks for environmental sediment experiments in hydraulic engineering, environmental engineering and marine engineering laboratories. Background technique [0002] In the experimental studies of river bed morphology evolution, mass transport, and moving bed model tests, it is necessary to flatten the sediment bed surface as the initial condition. If the bed surface is not flat, it will not only affect the initial conditions, but also affect the accuracy of the test. [0003] Such as "Hohai University Science and Technology Information", 1986 S2 period, "Interaction between water flow and sediment on the flat bed", N. Kebayasi S.N. Su Yuwei. In this paper, a mathematical model of the interaction between water flow and sediment in a flushable channel is established. The model is based on the conservation of mass and momentum of the flow and sediment. The model des...
