A clamping frame 701 is fixedly connected to the side of the middle part of the protective shell 5. A water spray pipe 702 is clamped on the clamping frame 701. The water spray pipe 702 consists of a nozzle and a liquid guide hose. The nozzle of the water spray pipe 702 is located in the cleaning chamber of the guide tube 6. The electrode 7 can be cleaned by connecting the cleaning liquid to the water spray pipe 702. The device adopts an intelligent management and control system to realize automatic cleaning, intelligent control of cleaning time intervals, cleaning time and other cleaning operations.

When the device is not in use, the isolation cover 19 is used to block the water spray pipe 702 to prevent dust and foreign matter from entering the water spray pipe 702.

[0031] When cleaning electrode 7, an automatic cleaning command is input to the analyzer to start cylinder 2 to lift electrode 7 from the detection water area to the specified position. Then, the water spray pipe 702 is connected to the cleaning liquid to rinse the surface of electrode 7 to remove dirt. After cleaning, cylinder 2 drives electrode 7 to descend for detection operation.

[0032] Example 2

[0033] Based on Example 1, please refer to Figure 3 , Figure 4 and Figure 8The outside of the cleaning chamber of the guide tube 6 is fixedly connected with four limit frames 8 distributed along the circumferential direction, and a clamping rod 9 is slidably arranged on the limit frame 8. The clamping rod 9 penetrates into the cleaning chamber to clamp the electrode 7, and a slope is arranged at the bottom of the clamping rod 9. When the electrode 7 is installed, the electrode 7 can squeeze the clamping rod 9 through the slope to move and make room for installation. A first elastic member 10 is sleeved on the clamping rod 9, and the two ends of the first elastic member 10 are respectively connected to the clamping rod 9 and the limit frame 8. A protective sleeve 18 is sleeved on the clamping rod 9, and the first elastic member 10 is located in the protective sleeve 18. The two ends of the protective sleeve 18 are respectively connected to the clamping rod 9 and the limit frame 8, and the protective sleeve 18 is used to protect the first elastic member 10.

[0034] When installing the electrode 7, the electrode 7 is inserted into the cleaning chamber of the guide tube 6. At this time, the electrode 7 contacts the inclined surface of the clamping rod 9. As the electrode 7 is pushed in, the clamping rod 9 is squeezed and moved outward, and the first elastic member 10 is compressed accordingly. After the electrode 7 is clamped, the clamping rod 9 is reset inward under the elastic force of the first elastic member 10 to clamp and fix the electrode 7, thereby achieving convenient installation.

A push plate 11 is slidably provided on the two guide plates 12. The push plate 11 is in contact with the clamping rod 9. The upward movement of the push plate 11 can squeeze the four clamping rods 9 to move outward at the same time. A second elastic member 13 is connected between the guide plate 12 and the push plate 11.

[0036] When removing the electrode 7 , the push plate 11 is pulled upwards, so that the push plate 11 pushes the four clamping rods 9 outwards at the same time, and there is no need to manually pull them apart one by one, so that the electrode 7 can be removed quickly and conveniently.

[0037] See also Figure 7 A ring bracket 14 is sleeved on the middle part of the cylinder 2, and two groups of guide rods 17 symmetrically distributed front and back are slidably arranged in the ring bracket 14.
