Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, and in particular to a reservoir comprehensive water source detection device and a monitoring method thereof. Background Art

[0002] As a water conservancy project, reservoirs play an increasingly important role in resource water conservancy, agricultural water conservancy, and urban water conservancy. Reservoirs not only have the functions of flood prevention, flood regulation, and flood storage, but also play a vital role in the optimization of water resources. In traditional farmland water conservancy, it is the lifeblood of agriculture. At the same time, with the development of social economy and the acceleration of urbanization, reservoirs have become an important source of water.

[0003] In the daily maintenance of reservoirs, water quality testing is the top priority of the work content. Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and the changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural water and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality status, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides.

[0004] For example, patent number CN217819556U discloses a water source detection device for reservoir engineering management, which includes a box body, straps are installed on both sides of the box body, a pressure sensor is installed on the front face of the box body, a controller is fixedly connected to the top of the box body cavity, a sealing device is arranged on the upper end face of the box body, a fixing plate is fixedly connected to the middle of the box body cavity, a detection tube is placed on the upper end of the fixing plate, a clamping device is arranged on the front and rear end faces of the box body cavity, a cleaning device is arranged at the bottom of the box body cavity, a cleaning groove is opened on one side of the bottom of the box body, a sealing plate is installed in the cleaning groove, when the pressure sensor reaches the required water depth, the controller starts the first motor to rotate the shaft, thereby driving the upper cover to rotate, the upper cover rotates to rotate the sealing hose, and then the corresponding pipe mouth is opened, and the water source is closed and sealed after the water source extraction is completed, so as to realize the extraction and detection of water sources with different water depths and improve the detection efficiency, but the device has the following shortcomings: 1. It is inconvenient to put the detection device into the reservoir by strapping, and the detection device is not easy to sink to the corresponding water depth for sampling.

[0005] 2. The collected water samples contain many impurities, which increases the workload of subsequent processing.
