Description

Technical Field

[0001] The present invention relates to the field of water quality monitoring, and in particular to a water quality monitoring device for an intelligent water supply network. Background Art

[0002] Smart water supply network water quality monitoring devices mainly focus on improving the accuracy and convenience of water quality monitoring. In current water quality monitoring technology, water quality monitoring sensors play a vital role. They can provide water quality data in real time or on demand, which is crucial for protecting public health and water resource management.

[0003] Existing water quality monitoring devices fall into two main categories. One type employs a continuous monitoring mode, where the sensor probe is permanently submerged in the water supply network to provide continuous, uninterrupted monitoring of water quality. This mode offers the advantage of instantly reflecting changes in water quality and enabling rapid response to sudden water pollution incidents. However, the long-term underwater operation environment leads to the accumulation of scale, microbial adhesion, and other impurities on the sensor probe. These deposits not only hinder direct contact between the sensor and the water but also interfere with its normal operation, ultimately reducing the accuracy of the monitoring data and affecting the accuracy of water quality assessments. The other type employs an intermittent or on-demand monitoring approach, where the sensor probe is briefly immersed in water for water quality testing based on a preset schedule or specific monitoring needs. While this approach mitigates the maintenance issues associated with long-term probe exposure to water, it still inevitably faces the problem of probe contamination in situations requiring frequent monitoring or emergency response. Furthermore, each operation requires manual intervention, making it cumbersome and inefficient.

[0004] The traditional solution to the probe contamination problem in the two monitoring methods mentioned above is to regularly dismantle, clean, and maintain the sensor probes. This process is not only time-consuming and labor-intensive, but in actual operation, it is often necessary to temporarily shut down the water supply pipeline to ensure the safety of operators and avoid water flow interference with maintenance work. Such maintenance measures not only increase operating costs, but may also cause inconvenience to residents' daily water use, especially in areas with tight water supply or critical service areas, where the impact is particularly significant.

[0049] like Figure 2-Figure 3 、 Figure 6-Figure 9As shown, in order to further improve the cleaning effect, a drying component is provided on the outside of the sensor probe 31, and the drying component includes an air pipe 38 arranged inside the outer periphery of the rotating drum 34, one end of the air pipe 38 extends to the outside of the sensor probe 31, and a plurality of air outlet holes 42 are provided on the side wall of the end corresponding to the sensor probe 31, a hollow ring body 33 is fixed to the outer wall of the end of the water quality monitoring sensor body 4 away from the sensor probe 31, and a second rotating ring 36 is provided on the inner side of the end of the ring body 33 close to the sensor probe 31, and the end of the air pipe 38 away from the sensor probe 31 passes through the second rotating ring 36 and extends to the inner side of the ring body 33 and is connected with the ring body 33, one side of the ring body 33 is connected to the hose 24, and the other end of the hose 24 is connected to the outside, a notch corresponding to the hose 24 is provided at one end of the first cylinder 21, and one end of the hose 24 extends outward from the notch.

The one-way valve can only discharge the fluid in the installation cavity 9 to the outside. A one-way valve is provided at one end of the air pipe 38. The one-way valve is configured to only suck external gas into the installation cavity 9.

[0052] like Figure 3 As shown, a filter screen 19 is provided on the inner side of one end of the water inlet 16 close to the monitoring cavity 8.

A water outlet 18 connected to the outside world is provided on the side of one end of the water inlet 16 close to the filter screen 19, and a one-way valve is provided on the water outlet 18. The one-way valve can only allow the water in the water inlet 16 to be discharged to the outside. A one-way valve is provided on the end of the water inlet 16 away from the filter screen 19. The one-way valve can only allow the water in the pipeline body 1 to enter the inner cavity of the monitoring cavity 8.

[0053] In addition, if Figure 5As shown, in order to ensure the stability of the sealing plug 10 when the connecting column 41 drives the third rotating ring 40 to rotate, a stabilizing component is provided in the hidden opening 25, and the stabilizing component includes a reinforcing head 26 movably arranged on the inner side of the inner wall of the hidden opening 25, and a first elastic member 27 is provided between one end of the reinforcing head 26 and the inner side of the inner wall of the hidden opening 25, and when the first elastic member 27 is in the reset state, one end of the reinforcing head 26 protrudes from the inner wall of the hidden opening 25. When the sealing plug 10 is located in the hidden opening 25, the reinforcing head 26 will be pushed into the inner side of the inner wall of the hidden opening 25, and the first elastic member 27 will be compressed. The first elastic member 27 generates a reverse force acting on the reinforcing head 26, and the reinforcing head 26 applies force to the sealing plug 10, thereby increasing the stability of the sealing plug 10, and can prevent the sealing plug 10 from being driven to rotate by the third rotating ring 40, reducing the wear of the sealing plug 10.

[0054] When in use, when the sensor probe 31 is in the hidden state, the sealing plug 10 is located inside the hidden opening 25 to seal the hidden opening 25, the second guide block 50 is located at the end of the second spiral groove 22 away from the hidden opening 25, and the rack 12 and the gear 29 are in a separated state. At this time, one end of the scraper 37 is in contact with the side wall of the sensor probe 31. If it is necessary to monitor the water quality of the water flowing through the pipeline body 1, the control driving source 13 drives the screw rod 15 to rotate, the screw rod 15 drives the second traction frame 14 to move, and the second traction frame 14 drives the first piston 6 to be positioned in the monitoring cavity 8. The first piston 6 moves, one end of the first piston 6 pushes the driving fluid 5 to move, and the other end generates negative pressure. The water in the pipeline body 1 enters the monitoring chamber 8 through the negative pressure in the water inlet 16, and the driving fluid 5 pushes the second piston 7 to move. The second piston 7 drives the rack 12 to move through the first traction frame 11. When the first piston 6 completely passes the hidden opening 25, the rack 12 starts to mesh with the gear 29. At this time, the rotating rod 28 is driven to rotate. Under the action of the first spiral groove 30 and the first guide block 46, the traction arm 32 drives the rotating drum 34 and the water quality monitoring sensor through the first rotating ring 35. The main body 4 is displaced as a whole toward the monitoring cavity 8. Under the action of the second spiral groove 22 and the second guide block 50, the drum 34, the connecting column 41, the third rotating ring 40, and the scraper 37 rotate as a whole. Under the action of the guide groove 51 and the guide column 43, the second elastic member 48 and the third elastic member 49 are gradually reset. After the reset, the scraper 37 is separated from the sensor probe 31, and then the sealing plug 10 enters the monitoring cavity 8. Before the sealing plug 10 is separated from the hidden port 25, the end of the drum 34 close to the sensor probe 31 will seal the hidden port 25 again. Then the sensor probe 31 enters the monitoring cavity 8. At this time, the monitoring cavity 8 is filled with water. The sensor probe 31 contacts the water to realize monitoring, and the water entering the monitoring cavity 8 can be filtered by the filter 19, which can reduce the influence of impurities on the sensor probe 31. Specifically, the filtered water sample is clearer, and the interference of impurities on the sensor probe 31 is reduced, thereby improving the accuracy of the detection result. In addition, the presence of impurities may cause wear or blockage to the sensor probe 31, shortening the service life of the instrument. The filtering operation can protect the instrument from such damage.

[0055] After the monitoring is completed, the driving source 13 reverses, and the screw rod 15 realizes the reset of the first piston 6. Due to the action of the one-way valve on the water inlet 16 and the one-way valve on the water outlet 18, the water in the monitoring chamber 8 will be discharged through the water outlet 18, which can reduce the driving fluid 5 remaining on the inner wall of the monitoring chamber 8 from mixing into the water in the monitoring chamber 8, avoiding returning to the pipe body 1 to affect the water quality, and can backwash the filter screen 19 to avoid blockage. During the reset of the first piston 6, the negative pressure of the driving fluid 5 will drive the second piston 7 to move. The second piston 7 also drives the rack 12 to move through the first traction frame 11, and the rack 12 drives the gear 29 and the rotating rod 28 to reverse. Under the action of the first guide block 46 and the first spiral groove 30, the traction arm 32 drives the rotating drum 34, the water quality monitoring sensor body 4, and the sealing plug 10 to be reset as a whole through the first swivel 35. The end of the rotating drum 34 close to the sensor probe 31 detaches from the hidden port 25, and then the sealing plug 10 enters the hidden port 25 for sealing. , during which the second guide block 50 cooperates with the second spiral groove 22, and the rotating drum 34 drives the air pipe 38, the connecting column 41, the scraper 37, and the third rotating ring 40 to rotate synchronously. At this time, due to the close contact between the sealing ring on the sealing plug 10 and the inner wall of the hidden opening 25, and the close contact between the reinforcing head 26 and the outer wall of the sealing plug 10, the sealing plug 10 will not rotate with it, reducing wear. Moreover, due to the action of the one-way valve on the impurity discharge port 17 and the negative pressure generated in the installation cavity 9 by the displacement of the second piston 7, the external gas enters the ring body 33 through the hose 24, enters the air pipe 38 through the ring body 33, and then blows toward the outer wall of the sensor probe 31 through the air outlet 42. Under the action of the guide column 43 and the guide groove 51, the scraper 37 gradually approaches the scraper 37, and the third elastic member 49 is compressed. When the scraper 37 contacts the outer wall of the sensor probe 31, the scraper 37 continues to rotate to clean the outer wall of the sensor probe 31. As it rotates, the second elastic member 48 is compressed, and the sealing plug 10 stops after completely entering the hidden opening 25.

[0056] It should be noted that the water in the guide groove 51 can be discharged from the drainage groove 52 into the installation cavity 9 , and when the second piston 7 approaches the installation cavity 9 , the water can be discharged through the debris discharge port 17 under the action of positive pressure.
