[0028] Through the above technical solution, by setting up a detection lower liquid hopper 201, the detection liquid flows into the lower liquid pipe 202 through the detection lower liquid hopper 201. At this time, when the water flows past the rotating blade 205, the rotating blade 205 can drive the rotating transmission rod 203 to rotate. When the rotating transmission rod 203 rotates, it can drive the rotating plate 206 to rotate. When the rotating plate 206 rotates, it can drive the brush mounting plate 207 to rotate. When the brush mounting plate 207 rotates, it can drive the cleaning brush 208 to rotate.

An outlet pipe 402 is connected to one side of the resin scrubbing end point detection housing 1. A shut-off valve 403 is installed inside the inlet pipe 401 and the outlet pipe 402 respectively. The shut-off valve 403 is electrically connected to the PLC controller 6.

[0033] Through the above technical solution, by setting the liquid inlet pipe 401, the detection liquid enters the resin wiping endpoint detection housing 1 through the liquid inlet pipe 401, the liquid outlet pipe 402 facilitates the discharge of liquid, and the shut-off valve 403 facilitates the control of the liquid inlet pipe 401 and the liquid outlet pipe 402.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, by setting up a detection lower liquid hopper 201, the detection liquid flows into the lower liquid pipe 202 through the detection lower liquid hopper 201. At this time, when the water flows through the rotating blade 205, the rotating blade 205 can drive the rotating transmission rod 203 to rotate. When the rotating transmission rod 203 rotates, it can drive the rotating plate 206 to rotate. When the rotating plate 206 rotates, it can drive the brush mounting plate 207 to rotate. When the brush mounting plate 207 rotates, it can drive the cleaning brush 208 to rotate. When the cleaning brush 208 rotates, it can clean the sensor detection component 3. Meanwhile, the cleaning brush 208 also drives the resin to clean the inner wall of the endpoint detection housing 1. At the same time, the rotating transmission rod 203 also drives the active bevel gear 212 to rotate. When the active bevel gear 212 rotates, it also drives the driven bevel gear 211 to rotate. When the driven bevel gear 211 rotates, it also drives the flipping mounting rod 210 to rotate in the flipping mounting plate 209. This achieves the effect of agitating the liquid in the lower part of the resin endpoint detection housing 1, preventing impurities from settling and affecting the detection effect. By setting the detection support frame 5, it is possible to facilitate the support of the resin endpoint detection housing 1.

[0036] By setting up turbidity sensor 301, the liquid can be detected for turbidity. pH sensor 302 can be used to detect the pH value of the liquid. Conductivity sensor 303 can be used to detect the conductivity of the liquid. Temperature sensor 304 can be used to detect the temperature. PLC controller 6 and PLC touch screen 7 can be set up to display the detection data of turbidity sensor 301, pH sensor 302, conductivity sensor 303 and temperature sensor 304.
