Description

Technical Field

[0001] The utility model relates to water quality monitoring equipment, in particular to an ultrasonic cleaning device for a water quality sensor. Background Art

[0002] The online water quality monitoring system uses 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. Due to long-term immersion in water, the sensors inside the online water quality monitoring system are easily covered by algae, plankton and other impurities, resulting in the inability of the water quality sensors to fully contact the water quality to be measured, and thus unable to obtain water quality data. Even if the water quality data is obtained, there will be some deviations. Therefore, it is necessary to manually maintain and clean the water quality sensors in the online water quality monitoring system frequently. When workers maintain and clean the water quality sensors, they often use a brush to brush the impurities on the monitoring end of the water quality sensor. Due to individual differences in the brushing strength of workers, even the same person controls the brushing strength differently at different times, which leads to the risk of damage to the monitoring end of the water quality sensor due to unstable brushing strength. In addition, the manual brushing process of the water quality sensor is relatively cumbersome, with low cleaning efficiency, and increases the labor intensity of workers. Utility Model Content

[0072] like Figure 1-6 As shown;

[0073] An ultrasonic cleaning device for a water quality sensor comprises a cleaning box 1 and a water quality sensor 2 mounted on the cleaning box 1; the cleaning box 1 is provided with an ultrasonic generating device 3 for cleaning the water quality sensor 2, and a water supply component 4 connected to the cleaning box 1 for flushing the water quality sensor 2.

[0074] A cleaning chamber 13 and a sensor installation chamber 14 which are interconnected are defined in the cleaning box 1 , and the water quality sensor 2 is installed in the sensor installation chamber 14 .

[0075] The cleaning box 1 is provided with a water inlet pipe 15 connected with the cleaning cavity 13 for installing the water supply assembly 4 , and a mounting hole 16 for installing the ultrasonic generating device 3 .

[0076] The ultrasonic generating device 3 includes a shell 31 arranged in the mounting hole 16, an ultrasonic generator 32 arranged in the shell 31, a stainless steel disc 33 arranged at one end of the shell 31 and connected to the output end of the ultrasonic generator 32, and a first sealing mechanism and a second sealing mechanism arranged on the shell 31 for sealing the ultrasonic generator 32.

[0080] Example 8.

[0081] like Figure 1-6 As shown;

[0082] An ultrasonic cleaning device for a water quality sensor comprises a cleaning box 1 and a water quality sensor 2 mounted on the cleaning box 1; the cleaning box 1 is provided with an ultrasonic generating device 3 for cleaning the water quality sensor 2, and a water supply component 4 connected to the cleaning box 1 for flushing the water quality sensor 2.

[0083] A cleaning chamber 13 and a sensor installation chamber 14 which are interconnected are defined in the cleaning box 1 , and the water quality sensor 2 is installed in the sensor installation chamber 14 .

[0084] The cleaning box 1 is provided with a water inlet pipe 15 connected with the cleaning cavity 13 for installing the water supply assembly 4 , and a mounting hole 16 for installing the ultrasonic generating device 3 .

[0085] There are two water inlet pipes 15, each of which is connected to a set of water supply components 4.

[0086] There are two water inlet pipes 15, and each water inlet pipe 15 is connected to a water supply component 4. When the water quality sensor 2 is cleaned, the water supply component 4 draws clean water into the cleaning chamber 13 through the water inlet pipe 15. Since there are two water supply components 4, the two water supply components 4 supply water alternately, so that the clean water in the cleaning chamber 13 forms a vortex shape, and the ultrasonic generating device 3 is started at the same time. The ultrasonic generating device 3 emits an ultrasonic wave and transmits it through the clean water, thereby cleaning the water quality sensor 2 in the sensor installation chamber 14. After cleaning is completed, the clean water takes impurities out of the cleaning chamber 13 when discharged.

[0087] Alternating water supply between the two groups of water supply components 4 can facilitate the formation of a vortex of clean water, which can rinse the water quality sensor 2 and can easily remove impurities in the cleaning chamber 13 after cleaning. Since there are two water supply components 4, even if one of the water supply components 4 is damaged, the other water supply component can still continue to work. Therefore, when the water quality sensor 2 is being cleaned, there is no clean water in the cleaning chamber 13, resulting in the water quality sensor 2 not being effectively cleaned.

The water baffle 17 is rotatably installed at the meeting point of the water inlet pipes 15 .

[0095] There are two water inlet pipes 15, and each water inlet pipe 15 is connected to a water supply component 4. When the water quality sensor 2 is cleaned, the water supply component 4 draws clean water into the cleaning chamber 13 through the water inlet pipe 15. Since there are two water supply components 4, the two water supply components 4 supply water alternately, and the water baffle 17 rotates along the direction of the water flow, thereby guiding the water flow, so that the clean water in the cleaning chamber 13 forms a vortex shape, and at the same time, the ultrasonic generating device 3 is started, and the ultrasonic generating device 3 emits an ultrasonic wave and transmits it through the clean water, so as to clean the water quality sensor 2 in the sensor installation chamber 14. After the cleaning is completed, the clean water takes impurities out of the cleaning chamber 13 when it is discharged.

[0096] By rotatably installing the water baffle plate 17 at the intersection of the water inlet pipe 15 , the water baffle plate 17 can guide the cleaning water flow so that the water flow can form a vortex in the cleaning chamber 13 , thereby facilitating the discharge of impurities and cleaning water in the cleaning chamber 13 .
