Embodiment Construction
[0015] Attached below Figure 1-5 , the present invention is described in detail.
[0016] figure 1 For the plan view of the test circulating water tank 14 that the present invention adopts, it is made up of three parts: circulating water tank 14, power unit 1 and sampling device 2, and this circulating water tank 14 is made of very little plexiglass to adsorption, migration, diffusion influence, puts On the horizontal plane 1m above the ground, the bottom surface should choose an appropriate slope according to the test water flow conditions. The width of the tank is 0.15m, and the total circumference is 10m. The length of the two straight sections is 3.5m, the inner diameter of the curved section is 0.41m, and the outer diameter is 0.56m. The two straight sections of the plexiglass circulating water tank 14 are the main operating areas in the test, and the test power unit 1 is set on one side, and the sampling device 2 is set on the other side. The test power unit 1 is comp...

The invention belongs to the field of water conservancy and relates to a hydraulic model, in particular to a hydraulic model for simulating yellow river sediment pollution regulations. The IPC classification number is E02B1 / 02. The adopted hydraulic model is composed of an organic glass circulation water tank, a power device and a sampling device. The power device is composed of a speed change motor, a transmission belt and a water wheel. A shell of the water wheel and blades are made of organic glass. The sampling device is composed of a fixing device and a sampling pipe. A longitudinal adjusting bolt and a transverse adjusting lead screw are arranged on the fixing device. The hydraulic model can dynamically simulate the migration and transformation process of pollution in natural river, the diffusion process and adsorption and desorption reaction mechanisms and interactions thereof can be better known, and therefore the hydraulic model is of a great significance.
Description
Technical field: [0001] The invention relates to a hydraulic model, in particular to a hydraulic model for simulating the adsorption and migration of pollutants by Yellow River sediment. The IPC international patent classification number of the model is E02B 1 / 02, which belongs to the field of water conservancy. Background technique: [0002] With the increasing shortage of water resources, the role of Yellow River water in protecting industrial and agricultural water and drinking water for residents in cities and rural areas along the Yellow River has also become increasingly prominent. How to ensure that the Yellow River water is not polluted, and how to eliminate pollution as soon as possible once polluted, is of great importance to protection. The water quality of the Yellow River is very important. Therefore, studying the adsorption of pollutants and their migration and diffusion laws by the Yellow River sediment has become an important topic for the management and prot...
