Circulating water flow device for simulating different riparian zone riverways

Abstract

The invention discloses a circulating water flow device for simulating different riparian zone riverways. The circulating water flow device comprises a support (1), a circulating water tank (2), a longitudinal slope adjusting mechanism and a circulating water device; the circulating water tank (2) is mounted on the support (1), and one end is hinged to the support (1); the longitudinal slope adjusting mechanism is mounted on the support (1) below the middle of the circulating water tank (2) and is used for supporting and adjusting the horizontal included angle formed by the circulating water tank (2) and the support (1); the circulating water tank (2) comprises a bottom plate (21), a front end plate (22), a back end plate (23) and two side plates (24); the two side plates (24) are hinged to two sides of the bottom plate (21) to form a V-shaped tank body having the variable opening angle and the V-shaped cross section; the front end plate (22) and the back end plate (23) are arranged attwo ends of the V-shaped tank body; the front end plate (22), the back end plate (23) and the V-shaped tank body are clamped and sealed by the aid of clamping mechanisms; heat insulation cotton (3) is arranged at the bottom of the V-shaped tank body; a simulation assisting device is placed on the heat insulation cotton (3); a water outlet (25) is formed below the front end plate (22); a water inlet (26) is formed above the back end plate (23); and the circulating water device is connected with the water inlet (26) and the water outlet (25) to realize circulating water supply to the V-shaped tank body. Continuous stepless adjustment of angles of transverse and longitudinal slopes can be realized simultaneously.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a circulating water flow device for simulating channels in different riparian zones. Background technique [0002] Slope is an important factor affecting the characteristics of slope flow and slope erosion. Compared with gentle slopes, the hydrodynamic characteristics and erosion characteristics under steep slope conditions have their particularity, and special research must be carried out. The research methods are mainly field experiments and indoor simulation experiments. Due to the difficulty of field observation, long period and complex influencing factors, it is difficult to conduct systematic research. The indoor variable slope test tank is one of the important test methods and facilities for studying the process and mechanism of slope erosion. Traditional slope-changing water tanks usually use three fulcrums to support the water tank, one power source, and ...

AI Technical Summary

Problems solved by technology

Traditional variable slope water tanks usually use three fulcrums to support the water tank, one power source, and two fulcrums to support the water tank. Therefore, it is difficult to completely synchronize the two fulcrums during the slope adjustment process, and repeated slope adjustments will cause great damage to the glass side wall

Most of the existing slope-changing water tanks adopt a support structure composed of two fulcrums. The whole water tank is fixed on a hinge support and a moving fulcrum, which is convenient for slope adjustment, but the scale of the water tank and the range of infinite slope adjustment are limited.

[0003] At present, most of the simulation test circulating water tanks only control a single factor, which has the characteristics of high cost, low utilization rate, low test efficiency, time-consuming and labor-intensive operation, and low precision. , flow rate, common hydraulic structures, temperature and other factors are taken into account the precise test device
