Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, and more specifically to a flow slot structure of a water quality detection sensor. Background Art

[0002] A water quality detection sensor is a device used to monitor various physical, chemical and biological parameters in water bodies. These sensors are usually designed to be directly immersed in water or installed around water bodies to monitor water quality in real time. When the water quality detection sensor is in use, it needs to be installed inside the circulation tank so that the water quality detection sensor can contact the water sample to be tested to obtain accurate water quality data.

[0003] However, in the existing water quality detection sensor flow channel structure, the inside of the flow channel is susceptible to the accumulation and adhesion of pollutants in the water, which may cause the sensor surface to be covered, affecting the accuracy and stability of the sensor. In addition, if the seal at the connection of the flow channel is not tight or the pipeline is aging, there is a risk of leakage, which will not only affect the accuracy of water quality monitoring data, but may also cause waste of water resources and environmental pollution.

[0028] Reference Figure 6 As shown, a closing plug 201 is provided on one side of the cleaning cover 2 close to the interior of the outer shell 1, and a limiting plate 202 is provided on the surface of the closing plug 201 close to the outer shell 1.

[0030] Reference Figure 7 As shown, an air inlet hole 1301 is opened at the top of the air inlet duct 13, and an air pressure cavity 1302 is opened inside the air inlet duct 13. The air pressure cavity 1302 is conducive to pushing the cleaning cotton plate 10 to rise and fall.

[0031] The working principle of the utility model is as follows: first, when in use, the water inlet valve 701 opened on the surface of the second pipe 7 is opened, so that the water source enters the filter cavity 601 opened in the filter box 6 through the second pipe 7, and then the impurities in the water are filtered through the one-way valve core 11 opened in the filter cavity 601, and then the water enters the water inlet hole 102 opened in the outer shell 1 through the circular hole 602, so that the filtered water enters the inner circulation tank 101 through the water inlet hole 102, and at this time, the water passes through the 8 opened in the inner circulation tank 101. The incoming water is blocked to prevent the impact force of the incoming water flow from affecting the detection result of the sensor body 9. The detected water is then discharged through the anti-leakage valve 5 opened on the side of the outer shell 1 away from the filter box 6. When it is used for a long time, the booster pump 4 is turned on to allow the booster pump 4 to pressurize the air pressure box 3. At this time, the air pressure in the air pressure box 3 enters the air pressure chamber 1302 through the air inlet hole 1301 opened in the air inlet pipe 13. At this time, the air pressure pushes the limiting plate 1004 in the air pressure chamber 1302, so that the limiting plate 1004 drives the telescopic column 1003 away from the air pressure chamber 1302. At this time, the cleaning cotton board 10 is restricted from descending by the limiting plate 202 opened on the surface of the closing plug 201 opened in the cleaning cover 2. The washing hole 1002 wipes the surface of the sensor body 9 to prevent the dirt on the surface of the sensor body 9 from affecting the detection data. Then the detected water is discharged to the connecting cavity 504 opened by the connecting pipe 503 through the position of the one-way valve core 11 movably connected in the pipeline cavity 502 opened by the first pipeline 501, and then discharged through the pipeline connected in the connecting cavity 504. When the pipeline connected in the connecting cavity 504 ages and leaks, the regulating valve 12 is rotated at this time, so that the regulating valve 12 drives the blocking rod 1201 to enter the connecting cavity 504. At this time, the entry of the blocking rod 1201 will squeeze the one-way valve core 11 flipped by the impact of the water flow, so that the one-way valve core 11 blocks the pipeline cavity 502. At this time, no water is discharged from the connecting cavity 504, avoiding the waste of water resources and environmental pollution.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
