Description

Technical Field

[0001] This invention relates to the field of environmental surveying technology, specifically to an integrated device for determining the dispersion coefficient of water bodies. Background Technology

[0002] Measuring the dispersion coefficient of water bodies is crucial for studying the transport and diffusion behavior of substances within them, and for gaining a deeper understanding of the migration and diffusion processes of various pollutants. By measuring the dispersion coefficient, we can assess and monitor the potential spread risk of various pollutants in water bodies. This helps identify pollution sources, predict the extent of pollutant diffusion, and develop relevant environmental protection measures. Measuring the dispersion coefficient helps us understand the velocity and direction of water flow, infer the movement of groundwater, and the interactions between water bodies. This is essential for the rational utilization and management of water resources, including groundwater and surface water. Measuring the dispersion coefficient can be used to predict the occurrence and development trends of natural disasters such as floods, debris flows, and river erosion. This helps us develop disaster response and early warning plans, reducing casualties and property damage. Understanding the transport and diffusion behavior of substances in water bodies can guide the design and optimization of environmental pollution control strategies. By reasonably estimating and simulating the spread of pollutants in water bodies, we can develop more effective control measures to reduce the impact of pollution on ecosystems and human health.

[0003] Measuring the water dispersion coefficient aims to provide important information about the migration and diffusion processes of substances in water bodies, and to provide a scientific basis for decision-making and planning in areas such as environmental protection, water resource management, natural disaster prevention and pollution control.

[0004] However, when measuring the dispersion coefficient of water bodies, the collection and transportation of water samples can easily lead to sample contamination, resulting in inaccurate measurements. Summary of the Invention

[0035] In practical applications, the present invention involves submerging the entire equipment in water and ensuring that the water surface completely covers the entire equipment. The main support pipe 11 of the structure has multiple flow velocity sensors fixed on the inner side wall of one end of the flow regulating support ring 151. The flow velocity sensors are existing technology. The floating balance mechanism 30 is used to adjust the suspension state of the entire equipment. The inner rod of the piston-driven telescopic rod 325 extends or retracts, which drives the volume control piston 321 to move inside the floating balance control tank 32 via the piston-driven rod 324. The movement of the volume control piston 321 changes the volume of the floating balance control tank 32 on the side of the volume control piston 321 away from the piston-driven housing 322, allowing external water to enter the floating balance control tank 32 through the floating balance flow pipe 326, or to discharge the water in the floating balance control tank 32 to the outside of the floating balance housing 31 through the floating balance flow pipe 326.

During operation, the axis of the main support pipe 11 is parallel to the water flow direction. The attitude adjustment mechanism 40 actively adjusts the attitude of the entire equipment to ensure that the axis of the main support pipe 11 is always consistent with the water flow direction. The attitude adjustment drive motor 42 drives the attitude adjustment propeller 43 to rotate, providing driving force for the entire equipment; The tilt mechanism rotating ring 452 is driven by a servo motor to rotate around the axis of the tilt mechanism fixed plate 451, which in turn drives the motor housing 453 and the attitude adjustment drive motor 42 to rotate together, changing the driving direction of the attitude adjustment propeller 43. One end of the runoff regulation support ring 151 faces the upstream of the water body, and the water body enters the main support pipe 11 of the structure and flows from one end of the water body flow channel 100 to the other end. The tracer is introduced into the calibration release tube 213. The tracer mixes with the water entering the water flow channel 100 and flows to the other end. The water mixed with the tracer passes through the support rings 221 of each detection mechanism in sequence. The concentration of the tracer at each position is detected by the concentration detection sensor 223, and then the dispersion coefficient of the water is calculated. The tracer is one of the existing technologies, specifically the tracer is... 131Solution I; Concentration detection sensor 223 is used for detecting tracers. 131 The prior art for solution concentration, concentration-assisted measurement sensor 233 is used for detecting tracers. 131 Existing techniques for solution concentration I; The tracer in the water can pass through the diffusion semipermeable membrane 122 and enter the interior of the structural side support tube 12. Multiple concentration auxiliary measurement sensors 233 on the auxiliary measurement support rod 232 are used to measure the concentration of the tracer diffusion along the radial direction of the main support tube 11 of the structure, thereby assisting in the calculation of the dispersion coefficient of the water. The fixed hinge shaft between the runoff regulating plate 153 and the runoff regulating support column 152 is driven to rotate by a servo motor, which adjusts the runoff regulating plate 153 to deflect. The water flow channel formed by the inner side of multiple runoff regulating plates 153 expands or shrinks at the end of the water flow channel away from the main support pipe 11, thereby adjusting the flow velocity of the water flowing through the water flow channel 100.
