Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a pipeline cleaning mechanism for a water quality monitoring system. Background Art

[0002] Generally speaking, a water quality analysis system is equipped with analysis equipment that can introduce water samples. Depending on the water quality analysis items of the water sample, an appropriate amount of reagent will be added to the water sample introduced by the analysis equipment to react with the pollutants in the water sample. The water quality status is determined by analyzing the reaction products.

[0003] Traditional water quality testing consists of a sampling water pump, a delivery pipeline, and a monitoring and analysis terminal. Since algae inside the water body can easily enter the pipeline along with the pump body, causing the algae to adhere to the inner wall of the pipeline, thus affecting the accuracy of water sampling.

[0004] Therefore, how to provide a pipeline cleaning mechanism for a water quality monitoring system to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a pipeline cleaning mechanism for a water quality monitoring system to solve the problem that traditional water quality testing consists of a sampling water pump, a delivery pipeline and a monitoring and analysis terminal. Since algae inside the water body can easily enter the pipeline along with the pump body, causing the algae to adhere to the inner wall of the pipeline, thereby affecting the accuracy of water sampling.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pipeline cleaning mechanism for a water quality monitoring system, comprising a second delivery pipe, a first delivery pipe, an analysis terminal, a backwash water pump and a sampling water pump;

[0008] The sampling water pump is provided with two water outlets, and the analysis terminal is provided with two water inlet ends, and the two groups of water inlet ends and water outlet ends are connected via a second delivery pipe and a first delivery pipe respectively;

[0009] The second solenoid valve and the fourth solenoid valve are respectively installed at both ends of the second delivery pipe, and the first solenoid valve and the third solenoid valve are respectively installed at both ends of the first delivery pipe;

[0010] The water outlet end of the backwash water pump is connected to the fourth solenoid valve through a flushing pipe, and the water inlet end of the backwash water pump is connected to a clean water inlet pipe.

[0011] Preferably, the second solenoid valve, the first solenoid valve, the third solenoid valve and the fourth solenoid valve are all three-way solenoid valves.

[0012] Preferably, the flushing pipe is connected to a medicine liquid tank, and a fifth solenoid valve is provided between the medicine liquid tank and the flushing pipe.

[0016] 1. The utility model is equipped with dual pipelines. When one pipeline is cleaned, the water sampling function is not affected by the other pipeline.

[0017] 2. When the first delivery pipe is cleaned, the present invention controls the solenoid valve so that the first delivery pipe and the second delivery pipe are connected through the connecting pipe. Then, the backwash water pump and the fifth solenoid valve are turned on, and the mixture of liquid medicine and clean water is delivered to the first delivery pipe and the second delivery pipe. When the first delivery pipe is filled with the mixture of liquid medicine and clean water, the connection of the connecting pipe is closed, so that the liquid medicine remains in the first delivery pipe for full reaction and decomposes the algae attached to the pipe wall. At the same time, the second delivery pipe normally collects water and delivers it to the analysis terminal for sampling. When the second delivery pipe is cleaned, the liquid medicine is first filled into the second delivery pipe so that the liquid medicine and the liquid medicine in the second delivery pipe fully react, and the first delivery pipe continues to sample.
