Description

Technical Field

[0001] The utility model relates to the technical field of river water quality detection, in particular to a river water quality detection device. Background Art

[0002] River water quality testing refers to the process of measuring and analyzing various pollutants and their concentrations in rivers, lakes, reservoirs and other water bodies to evaluate the quality of the water body. River water quality testing usually includes four steps: water sample collection, pretreatment, analysis and testing, and result evaluation. There are many ways to collect water samples, such as surface sampling, sediment sampling, underwater sampling, etc. Pretreatment is mainly to remove suspended matter, colloids, etc. in the water body to ensure the accuracy of subsequent analysis and testing. The analysis and testing methods mainly include physical, chemical and biological means, such as pH determination, organic pollutant determination, microbial counting, phytoplankton counting, etc.

[0003] However, in the current existing technology, in order to ensure the accuracy of the water quality detection of rivers, the floating garbage in the water sample is generally removed during pre-treatment, leaving the river water for detection. However, the garbage content in the river will also have a great impact on the water quality, not only reducing the water quality but also causing flow blockage and affecting the drainage effect. Therefore, only testing the river water cannot guarantee the accuracy of the river detection. Utility Model Content

[0007] As a preferred solution of the utility model, both ends of the main pipe are connected to the sampling pipe and the transfer box respectively through sleeves, the water pipe is connected to the water outlet of the transfer box, and the other end of the water pipe extends into the sample storage box.

[0008] As a preferred solution of the utility model, the filter is located in the transfer box and is slidably connected by a slide rail. After the filter is installed, the feed port corresponds to the injection end of the transfer box, and the motor is connected to the top of the filter by bolts.

[0009] As a preferred solution of the utility model, the output end of the motor is connected to the fixed shaft through a coupling, the other end of the fixed shaft extends into the filter and is rotatably connected to the inner wall of the filter through a bearing, and the stirring rod is coaxially connected to the fixed shaft.

[0010] As a preferred solution of the utility model, the two conical tubes are connected to the front end of the sampling tube through a sleeve, and the front end of the conical tube is a conical structure, which can divide the water flow when the water flows through to make impurities move away to both sides, and the two fixed frames are connected to the outer wall of the main pipe by welding, and the two conical tubes are respectively connected to the two fixed frames.

[0011] As a preferred solution of the utility model, the two fixing frames are connected to the cavity in the main pipe, and the multiple nozzles are embedded and connected to the inner wall of the cavity. Water flows through the nozzles and can be injected into the main pipe in the form of bubbles, covering the inner wall of the main pipe through the bubbles.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: in response to the problems raised in the background technology, the present application adopts a collection component, and the sampling tube can be controlled to be opened regularly through the control valve in the sampling tube to perform regular testing of the water quality in the river. The river water entering the sampling tube will be first transported to the transfer box through the main pipe. After the water flows into the transfer box, the impurities in the water are filtered through the filter screen. At the same time, the impurities in the filter screen can be stirred by rotating the stirring rod to prevent the impurities from accumulating at the bottom of the filter screen and affecting the water flow. The river water is filtered and pre-treated through the filter screen. After the impurities are filtered, the remaining water flow is transported to the sample box through the water pipe for transportation to water quality testing. The impurity content in the river water can be calculated by the impurity content in the filter screen, thereby obtaining the impurity content in the water.

[0013] While the main pipe is transporting the collected river water to the transfer box, the valve of the conical pipe can be opened to allow the water in the river to pass through the conical pipe into the fixed frame outside the main pipe and engage the nozzle in the cavity inside the main pipe to spray out the water in the form of bubbles, which can cover the pipe wall of the main pipe to prevent impurities from sticking to the pipe.

[0014] The utility model can filter and collect impurities in collected river water, detect the impurity content in the river water, and is convenient for cooperating with water quality detection to improve the accuracy of detection. When the river water is transported in the pipeline, the pipe wall can be covered with water bubbles to prevent impurities from adhering to the pipeline, thereby ensuring the smooth flow of the pipeline.
