Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection equipment, and particularly relates to an online cleaning device for a water quality sensor. Background Art

[0002] Online water quality monitoring systems use dissolved oxygen sensors, pH sensors, and other sensors to form a water quality sensor group for real-time measurement of various water quality indicators, providing dynamic monitoring of aquaculture water bodies for ecological fish farming. Existing online water quality monitoring systems generally use a water pump to pump the water to be tested into a monitoring box. The water quality is tested using a water quality sensor. The water pump pumps the water to be tested into the monitoring box. When the water to be tested enters the monitoring box through the water inlet pipe, it will rotate along the inner wall of the monitoring box. At the same time, because the drain pipe and the water inlet pipe are in a vertical state, the water to be tested will form a vortex in the monitoring box. Under the influence of the vortex, the water to be tested will rotate at high speed through the drain pipe and be discharged from the monitoring box. This will cause an air channel to form in the middle of the vortex, and air will enter the monitoring box through the air channel, thereby affecting the detection accuracy of the water quality sensor.

The U-shaped or V-shaped guide tube 10 can form a water storage area at the bend, and the test water can be retained in the guide tube 10 in the water storage area, thereby preventing air from entering the cleaning box 1 through the guide tube 10, thereby preventing air from entering the cleaning box 1 and affecting the detection accuracy of the water quality sensor 2.

[0058] Example 5.

[0059] like Figure 1-10 As shown, the utility model provides an online cleaning device for a water quality sensor 2, comprising a cleaning box 1, a cleaning mechanism 3 arranged in the cleaning box 1 for cleaning the water quality sensor 2, a driving mechanism connected to the cleaning mechanism 3 for driving the cleaning mechanism 3 to operate, a drainage mechanism connected to the cleaning box 1 for discharging test water, and a water supply mechanism connected to the cleaning box 1 for conveying water to be tested; a water outlet pipe 4 is provided between the cleaning box 1 and the drainage mechanism, and a partition plate 5 for eliminating vortex is provided in the water outlet pipe 4.

[0068] Based on Example 5, this Example 6 provides a more preferred structure of the cleaning mechanism 3, specifically: the cleaning mechanism 3 includes a first strong magnetic ring 13 threadedly connected to the high-pressure chamber 11 and separating the high-pressure chamber 11 from the detection chamber 12, a cleaning copper tube 14 slidingly arranged in the first strong magnetic ring 13, a second strong magnetic ring 15 arranged on the cleaning copper tube 14 and located in the high-pressure chamber 11, a third strong magnetic ring 16 slidingly arranged on the cleaning copper tube 14 and located between the first strong magnetic ring 13 and the second strong magnetic ring 15, a cleaning head 17 arranged on the cleaning copper tube 14 and located in the detection chamber 12, and a brush 18 arranged on the cleaning head 17; the magnetism between the third strong magnetic ring 16 and the second strong magnetic ring 15 repel each other, the magnetism between the third strong magnetic ring 16 and the first strong magnetic ring 13 repel each other, and the brush 18 is provided with a cutout 19.

[0069] The utility model has a first strong magnetic ring 13 which is threadedly connected to the high-pressure chamber 11 and separates the high-pressure chamber 11 from the detection chamber 12. A cleaning copper tube 14 is slidably arranged on the first strong magnetic ring 13, and one end of the cleaning copper tube 14 is provided with a second strong magnetic ring 15 located in the high-pressure chamber 11, and the other end is provided with a cleaning head 17 located in the detection chamber 12. A third strong magnetic ring 16 which is located between the first strong magnetic ring 13 and the second strong magnetic ring 15 is slidably arranged on the cleaning copper tube 14, and a brush 18 is mounted on the cleaning head 17. The brush 18 is provided with a cutout 19.

[0070] The utility model has an internal thread on the inner wall of the high-pressure chamber 11, and an external thread matching the internal thread on the outer wall of the first strong magnetic ring 13. The first strong magnetic ring 13 is threadedly connected to the high-pressure chamber 11. The threaded connection can facilitate the installation and disassembly of the cleaning mechanism 3.

[0071] When the utility model is in use, the driving mechanism delivers high-pressure water to the high-pressure chamber 11. Under the action of the water pressure, the second strong magnetic ring 15 pushes the cleaning copper tube 14 to slide in the first strong magnetic ring 13, so that the cleaning head 17 extends. At the same time, the cleaning water enters the cleaning head 17 through the cleaning copper tube 14 and is discharged through the incision 19 on the brush 18. The thrust generated by the discharge of the cleaning water pushes the brush 18 to rotate. Since all the water quality sensors 2 are distributed on the inner wall of the detection chamber 12, the brush 18 can clean all the water quality sensors 2 during the rotation process.

[0072] The second strong magnetic ring 15 of the utility model will be close to the third strong magnetic ring 16 under the action of water pressure. Since the magnetism between the third strong magnetic ring 16 and the second strong magnetic ring 15 repel each other, the second strong magnetic ring 15 pushes the third strong magnetic ring 16 to approach the first strong magnetic ring 13, and the magnetism between the third strong magnetic ring 16 and the first strong magnetic ring 13 repel each other, so that the third strong magnetic ring 16 and the first strong magnetic ring 13 will not be adsorbed together, thereby reducing the resistance encountered by the cleaning head 17 when rotating, making it easier to clean the water quality sensor 2.
