Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project monitoring, in particular to a water quality monitoring auxiliary device for water conservancy projects. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, chromaticity, 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. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, it is sometimes necessary to measure the flow rate and flow.

[0003] A timed sampling auxiliary device for water quality monitoring in a water conservancy project disclosed in Chinese utility model patent application CN113624553A includes a cam, a fixed shaft is movably connected to the rear of the cam, an electromagnetic push block is movably connected to the inside of the fixed shaft, and a push rod is movably connected to the outside of the electromagnetic push block. When the push plate rotates around the fixed shaft, the piston is driven to move up and down, which causes a pressure change in the extraction chamber. Automatic sampling is achieved by using the pressure difference, which reduces labor costs. The position and depth of each sampling are fixed, making the sampling result more accurate. The electromagnetic push block is energized at a fixed time by a timing device, and the block is pushed out by the magnet and the push rod. At this time, the rotating shaft can continue to drive the mounting bracket to rotate, so that the device can perform continuous multiple sampling. By setting the time for the timing device in advance, the device can automatically perform interval sampling according to the set time. The sampling interval is set by the machine, instead of manual sampling, making the sampling effect more accurate.

[0004] However, when monitoring the water quality of rivers and oceans, auxiliary monitoring devices need to be placed in the monitoring environment. The historical location of the device cannot be recorded and queried, which can easily cause the monitoring equipment to be disconnected and lost. The device monitors underwater, which makes it inconvenient for staff to recover and salvage it after the monitoring work is completed, and it is not convenient for multiple reuse.
