A simulation device for continuous and stable flowing water

Abstract

A simulation device of a continuous and stable flowing water body comprises a fixed table, a motor, an annular water tank and an annular baffle. The fixed table is horizontally arranged, the motor is perpendicularly arranged on the bottom of the fixed table, the annular water tank is perpendicularly arranged on the fixed table, and the motor is in drive connection with the annular water tank. The fixed table is provided with a fixed support, the annular baffle is perpendicularly arranged in the annular water tank through the fixed support, and the annular baffle is provided with a notch with a downward opening. The axial line of the annular water tank, the axial line of the annular baffle and the axial line of the motor are the same. The simulation device of the continuous and stable flowing water body has the advantages of being low in energy consumption, high in efficiency, and capable of automatically adjusting hydrodynamic conditions (flow velocity); the simulation device of the continuous and stable flowing water body is capable of carrying out simulation on different hydraulic conditions for natural water bodies like landscape water bodies and city internal riverways, providing reliable laboratory simulation conditions for researches like microbial growth in similar water bodies and hydrodynamic parameter changes of the water bodies, and capable of simulating continuous and stable flowing states of riverway-type natural bodies.

Description

technical field [0001] The invention relates to a simulation device for simulating the flow of natural river-type water bodies, relates to the fields of environmental protection, water conservancy engineering and the like, and is suitable for simulation tests of natural water bodies such as landscapes and river-type water bodies under laboratory conditions. Background technique [0002] In recent years, the river-type water environment in many cities has been seriously polluted and destroyed. The polluted water stagnates, silts up or flows slowly, and the self-purification ability of the water body deteriorates. and other functions are greatly reduced, and it is urgent to restore the water quality of urban river-type water bodies. However, due to the limitations of experiments and economic conditions, it is difficult to conduct experimental research in real natural water bodies, and laboratory simulation methods are often used for research. At present, domestic simulation d...

Problems solved by technology

However, since the entire bucket rotates together with the water body in the bucket, under different diameters, the distribution of water flow velocity is uneven and the range is wide, it is difficult to reflect the status of biological growth under the average flow velocity of water flow

Secondly, when the rotation speed of the bucket is high, there is a situation that the water flow cannot be carried, that is, the water flow in the bucket will be close to a static state, and at the same time, it is difficult to measure the hydraulic conditions such as the water flow velocity.

[0006] Due to the design method of the above-mentioned devices, there are certain defects, which are different from the water flow conditions in the real river.
