[0016] In order to clearly illustrate the technical features of the scheme, the following will be described through specific embodiments.

[0017] like Figure 1 The present invention relates to an online instrument electrode cleaning device for a heating network circulating water system, comprising a flow tank 2 connected to an inlet pipe 4 and an outlet pipe 6, wherein an electrode insertion hole is provided at the top of the flow tank for inserting instrument electrodes.

[0018] A spiral coil 3 is fixedly installed inside the flow pool 2. The axial inner hole of the spiral coil 3 forms a space for placing the instrument electrode. Several water spray holes 9 facing the instrument electrode are opened on the tube wall of the spiral coil. One end of the spiral coil 3 is connected to the flushing water inlet pipe 7. A flushing valve 8 located outside the flow pool 2 is installed on the flushing water inlet pipe 7.

[0019] The axial inner hole of the spiral coil is located directly below electrode insertion hole 1 and is coaxial with electrode insertion hole 1. The axial inner hole of the spiral coil refers to the internal space enclosed by the tube body of the spiral coil. The axis of the axial inner hole of the spiral coil is consistent with the axis of the spiral coil and extends in the vertical direction.

[0020] The axis of the spiral coil is aligned with the axis of the instrument electrode, and one end of the spiral coil within the flow chamber is sealed. Specifically, the spiral coil is placed vertically, with its lower end sealed and supported at the bottom of the flow chamber, and its upper end connected to the flushing water inlet pipe 7.

[0021] In this embodiment, the water inlet pipe 4 is located at the bottom of the flow tank 2, and a water inlet valve 5 is installed on the water inlet pipe. The water outlet pipe 6 is located on the upper part of the side wall of the flow tank. The connection position between the water outlet pipe and the flow tank is higher than the height of the spray hole on the spiral coil in the height direction, so as to prevent water after rinsing the electrode from flowing out of the water outlet pipe.

[0022] The cleaning device in this embodiment also includes a drain pipe with a drain valve 10 installed. The outlet end of the drain pipe is fixedly connected to and communicates with the outlet pipe 6, and the inlet end of the drain pipe is fixedly connected to and communicates with the inlet pipe 4. The connection point between the drain pipe and the inlet pipe is located between the flow pool 2 and the inlet valve 5.

[0023] During normal use, the inlet valve is open, while the flushing valve 8 and drain valve 10 are closed. Circulating water enters the flow tank through the lower inlet pipe and flows out through the upper outlet pipe 6. The instrument electrode is inserted into the axial inner hole of the spiral coil through the electrode insertion hole for water quality testing. When flushing the instrument electrode is required, the inlet valve 5 is closed, and the flushing valve 8 and drain valve 10 are opened. A water pump connected to the flushing water inlet pipe 7 pumps flushing water into the spiral coil. The flushing water is sprayed onto the surface of the instrument electrode through the spray holes on the spiral coil, removing contaminants adhering to the surface. The flushed water then flows downwards into the drain pipe and out, thus cleaning the surface of the instrument electrode, preventing impurities from accumulating on the flow tank and the instrument electrode surface, reducing corrosion and wear on the instrument electrode and flow tank components, and extending the service life of the online instrument and flow tank.

[0024] In practical applications, regular backwashing can promptly remove impurities and dirt from the flow tank, preventing interference with sensor measurements and ensuring the accuracy and reliability of online instrument measurements. Valve control can be automated using PLC to achieve timed automatic backwashing, reducing the workload and frequency of manual maintenance and improving the stability and operational efficiency of the entire online monitoring system.

[0025] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
