Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a water quality monitoring device with a sampling mechanism. 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, 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. 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] The utility model patent with announcement number CN211717499U in the prior art discloses a water quality monitoring system with automatic diagnosis function, including a waterproof base and a photovoltaic panel. An operation panel is installed on the side of the waterproof base, an electric control cabinet and a detection cabinet are installed on the top of the waterproof base, a five-parameter water quality monitoring sensor is installed on the side of the detection cabinet, the bottom of the five-parameter water quality monitoring sensor is connected to the water suction pipe through an electric ball valve, and the top of the five-parameter water quality monitoring sensor is connected to the sampling pump installed on the bottom plate inside the detection cabinet through an overflow valve. It uses solar energy as a power source, transforms solar power to charge the battery block as the power source of the utility model, and has good energy-saving and environmental protection performance. At the same time, the utility model can monitor the transformer fault in real time. In case of fault, it will be fed back to the remote control end of the staff through a wireless signal, and the GPS coordinates will be marked to facilitate the staff to quickly carry out maintenance.

[0004] However, the device still has some defects during use. For example, the pumping pipe is easy to extract some debris in the water during the sampling process, which causes the pipe to be blocked and affects the smooth sampling. At the same time, since the device is directly fixed on the shore, when the water level of the river changes, the low water level may cause the pumping pipe to be unable to contact the river water, and the high water level may cause the river water to submerge the device, causing inconvenience in use. Therefore, a water quality monitoring device with a sampling mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water quality monitoring device with a sampling mechanism, comprising a floating plate, a water quality monitoring instrument body is fixedly installed on the top of the floating plate, a sampling mechanism is arranged on the outside of the water quality monitoring instrument body, a cleaning mechanism is arranged on the outside of the sampling mechanism, and a mounting assembly is arranged on the outside of the floating plate;

[0010] Furthermore, the lower end of the insertion rod is in a pointed cone shape, and a pad is fixedly connected to the lower side wall of the insertion rod.

[0011] Furthermore, the number of the inserting rods and the number of the sliding sleeves are both two, and they are respectively located on the left and right sides of the floating plate.

[0012] Furthermore, the sampling water pump and the driving motor are both fixedly mounted on the top of the floating plate, and the output end of the sampling water pump is connected to the input end of the water quality monitor body.

[0017] 1. The water quality monitoring equipment with a sampling mechanism uses the filter on the sampling tube to filter large impurities in the water to prevent large impurities from entering the sampling tube. When a large amount of impurities are attached to the surface of the filter, the drive motor is started to drive the connecting shaft to rotate, and the brush is driven to rotate, and the impurities on the surface of the filter are cleaned by the brush. At the same time, the river water detected by the water quality monitor body is extracted by the flushing water pump, and the filter is reversely flushed through the installation pipe and the sampling tube, thereby improving the cleaning efficiency of the filter, ensuring the water flow efficiency of the filter, playing a good anti-blocking performance, ensuring the stability of sampling, and having good practicality.

[0018] 2. The water quality monitoring equipment with a sampling mechanism uses a floating plate to float on the water surface to adapt to different water levels.
