Bank slope model pollution dispersion experiment device

Abstract

The invention belongs to the technical field of environment engineering equipment manufacturing, and particularly relates to a complex type bank slope model pollution dispersion experiment device of a tank-in-tank structure for analyzing and treating horizontal and vertical dispersion parameters and characteristics of complex bank slope pollutants. The main body structure consists of three parts including an outer water tank and foundation base unit, an inner water tank and dosing box unit and a grid and mechanical drive unit in a combined mode; the tank-in-tank structure that the outer side of the inner water tank is sleeved by an outer water tank is adopted, the inner water tank internally simulates the complex bank slope water area, and the bottom is provided with a communicating hole, so that the pressures inside and outside are equal; a vibration grid is used in the inner water tank for simulating the turbulent water body environment; the waterproof and sealed outer water tank bears the structure pressure and provides an installation space for the inner water tank, and provides the environment condition of a static water area for the experiment model. The complex type bank slope model pollution dispersion experiment device is simple in structure, is convenient to operate, can keep the integrity, the experiment parameter accuracy and reagent conservativeness of the complex bank slope in the experiment process, and improve the experiment success rate.

[0002] Environmental hydraulics is a new branch of hydraulics. It studies the law of pollutant mixing and transport in water bodies and its application. The main goal is to explore the relationship between the concentration of pollutants due to mixing and transport with time and space. Water quality evaluation and forecast, water quality planning and management, planning and design of sewage projects, and reasonable measures for water resource protection provide basic basis. Simulation experiment is one of the main research methods; The key technical problems that need to be solved urgently in the development of hydraulics. The existing pollution diffusion experimental equipment or models have single functions, difficult parameter analysis and low precision, and the experimental water depth is shallow, resulting in short distances and short The uniform mixing in the vertical direction is formed within a short period of time, which is inconsistent with the pollution diffusion of the actual water area; there is no experimental equipment or equipment on the market to study the pollution diffusion of complex bank slopes. The rivers and reservoirs with complex slope changes do not match, and it is difficult to solve the cutting-edge technical problems in the process of scientific development; The upper part of the façade with variable angle structure is open, and the bottom surface and the joints between the left, right and rear façades are respectively bonded with waterproof superglue. It is connected with the peripheral water supply tank, and the water discharge valve is installed in the lower right corner of the bottom. After the façade of the water tank is installed, it is fastened with channel steel frames and screws. The façade variable-angle water tank is divided into upper and lower parts. The lower part of the sloping plate is equipped with a device for fixing the sloping plate, and the inside of the right façade of the façade variable-angle water tank is equipped with a sponge adsorption device; The total water pressure on the front and rear facades is prone to slight deformation, which causes the glue bonding between the front and rear facades of the tank to be separated from the inclined bottom, forming gaps, displacement and distortion of the inclined bottom, and the edges of the partitions appearing The phenomenon of drug leakage destroys the integrity of the experimental device and affects the geometric accuracy of the experimental parameters, the conservation of the drug and the success rate of the experiment
