Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and more specifically to an online pH meter testing system. Background Art

[0002] A pH meter is an instrument used to measure the acidity or alkalinity of a solution. It determines the pH value, or acidity or alkalinity, of a solution by detecting the concentration of hydrogen ions in the solution. By using a pH meter, users can accurately and in real time monitor the acidity or alkalinity of a solution, thereby enabling effective monitoring and adjustment, ensuring the quality and safety of processes and products. This makes the pH meter an indispensable tool in fields such as laboratory research, industrial production, and environmental monitoring.

[0003] In related technologies, after the detection work is completed, the probe is placed in the chamber for cleaning. For example, the prior art publication number CN216847772U provides an online pH meter. The wastewater sample to be tested is placed stably inside the tray. After placement, the probe is inserted into the sample, and the pH meter body is used to detect the sample. After the test is completed, the probe is cleaned by introducing cleaning solution into the chamber for storage. The probe is then inserted into the chamber for cleaning. After cleaning, the probe is removed.

[0004] However, the existing technology has the following drawbacks: the positions of the housing and the probe are fixed, and the probe needs to be disassembled when cleaning. The cleaning process is complicated, which makes it impossible to quickly detect multiple sewage samples, thus reducing the detection efficiency of sewage. Summary of the Invention

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The pH meter online detection system involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] See Figure 1 , Figure 2 As shown, the present invention provides an online pH meter detection system, including a protective component 2, a pH detection electrode rod 3, a protective tube shell 4, a cleaning mechanism 5, a lifting mechanism 6, and a telescopic protective cover 8;

[0069] Specifically, such as Figures 3-4 As shown, the cleaning mechanism 5 includes a cleaning brush 503, which is located inside the protective housing 201 and sleeved on the outer wall of the pH detection electrode rod 3.

[0070] like Figure 5-Figure 8As shown, the lifting mechanism 6 includes a lifting frame 607, a lifting toothed ring 602, and a spiral guide rail 606. The lifting frame 607 can slide within the protective housing 201. In this embodiment, a vertical guide rail 205 is provided inside the protective housing 201. The lifting frame 607 is slidably connected to the vertical guide rail 205 and is connected to the pH detection electrode rod 3. Under the action of the driving device 7, the pH detection electrode rod 3 is driven to move within the cleaning circular brush 503. The lifting toothed ring 602 is rotatably connected to the lifting frame 607, and a spiral groove 603 is provided on the outer side of the lifting toothed ring 602. The spiral guide rail 606 cooperates with the spiral groove 603, and the spiral groove 603 can slide on the spiral guide rail 606.

[0071] In addition, the cleaning mechanism 5 also includes a linkage toothed ring 5011 and a cleaning toothed ring 502, wherein: the linkage toothed ring 5011 is rotatably connected to the protective component 2, and the linkage toothed ring 5011 is drive-connected to the lifting toothed ring 602; the cleaning toothed ring 502 is sleeved on the outside of the cleaning round brush 503 and is drive-connected to the linkage toothed ring 5011.

[0072] Specifically, the linkage gear ring 5011 is meshed with the drive gear 501; the lifting gear ring 602 is meshed with the power gear 601; the centers of the drive gear 501 and the power gear 601 are connected through the transmission rod 504, and the power gear 601 and the transmission rod 504 are slidably connected.

[0073] In addition, such as Figures 9-10 As shown, a cleaning assembly 9 is also provided on the outside of the pH detection electrode rod 3. The cleaning assembly 9 includes: a cleaning pump 905, an infusion pump 906, a first delivery pipe 902, a second delivery pipe 904, and two sets of connecting pipes 901. Among them, the cleaning pump 905 is located outside the protective assembly 2 and is used to deliver clean water; the infusion pump 906 is located outside the protective assembly 2 and is used to deliver cleaning solution; the first delivery pipe 902 has its inlet end connected to the cleaning pump 905 and its outlet end extended to the cleaning brush 503; the second delivery pipe 904 has its inlet end connected to the infusion pump 906 and its outlet end extended to the cleaning brush 503; the outlet ends of the two sets of connecting pipes 901 are respectively connected to the cleaning pump 905 and the infusion pump 906, and their inlet ends are respectively connected to the clean water storage device and the cleaning solution storage device.

[0074] A water-passing cover 507 is provided between the liquid outlet end of the first conveying pipe 902, the liquid outlet end of the second conveying pipe 904 and the cleaning circular brush 503; the water-passing cover 507 is sleeved on the pH detection electrode rod 3, and multiple small holes are opened on the water-passing cover 507.

[0075] like Figure 1 , Figure 9 Figure 11As shown, specifically, the protective component 2 includes a protective shell 201, a top cover 202 fixedly mounted on the top of the protective shell 201, a fixing frame 204 fixedly mounted on the top of the top cover 202, a bottom connecting ring 203 fixedly mounted on the bottom of the protective shell 201, a direct tube 801 symmetrically fixedly mounted on the top of the fixing frame 204, a protective tube shell 4 fixedly mounted on the top of the fixing frame 204, a detection controller 1 mounted on the other end of the protective tube shell 4, a spring wire mounted on the top of the pH detection electrode rod 3, the spring wire being located inside the protective shell 201 and the direct tube 801, and vertical guide rails 205 symmetrically fixedly mounted on the inner side of the protective shell 201, the vertical guide rails 205 being fixedly connected to the top cover 202.

[0076] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning mechanism 5 includes a drive gear 501, a linkage gear ring 5011 meshing on the outer side of the drive gear 501, a cleaning gear ring 502 symmetrically meshing on the inner side of the linkage gear ring 5011, a cleaning round brush 503 fixedly mounted on the inner side of the cleaning gear ring 502, a water-passing cover plate 507 fixedly mounted on the top of the inner side of the cleaning round brush 503, the top of the water-passing cover plate 507 having multiple small holes, a double-hole fixed shell 506 rotatably mounted on the top of the cleaning round brush 503, a transmission rod 504 fixedly mounted on the top of the drive gear 501, the transmission rod 504 rotatably mounted on the bottom end of the top cover 202, a fixed carrier 505 rotatably mounted on the outer side of the transmission rod 504, the fixed carrier 505 being fixedly connected to the double-hole fixed shell 506 by bolts, the linkage gear ring 5011 slidingly mounted on the inner side of the bottom connecting ring 203, and the fixed carrier 505 being fixedly connected to the protective shell 201 by bolts.

[0077] The lifting and lowering of the spiral ring 602 causes it to rotate, which in turn drives the power gear 601 to rotate. The power gear 601 then drives the transmission rod 504 to rotate. Simultaneously, the transmission rod 504 drives the drive gear 501 to rotate, which in turn drives the linkage ring 5011 to rotate. The rotation of the linkage ring 5011 simultaneously drives the two cleaning rings 502 to rotate, which in turn drives the cleaning brush 503 to rotate. The rotation of the cleaning brush 503 cleans the pH detection electrode rod 3, removing residual dirt and liquid. This allows the pH detection electrode rod 3 to be cleaned without disassembly, improving detection efficiency. The top of the water-passing cover 507 has multiple small holes for the passage of cleaning solution and clean water. The cleaning solution and clean water fall onto the cleaning brush 503 and are used when cleaning the pH detection electrode rod 3.

[0078] See Figures 1-8 As shown, the lifting mechanism 6 includes a power gear 601, which is slidably disposed on the outside of the transmission rod 504. A lifting spiral ring 602 is meshed on the outside of the power gear 601. A spiral groove 603 is formed on the outside of the lifting spiral ring 602. An annular rail 604 is fixedly disposed at the bottom end of the lifting spiral ring 602. Fixing blocks 605 are symmetrically slidably disposed on the inner side of the annular rail 604. The fixing blocks 605 are fixedly connected to the lifting frame 607 by bolts. A spiral guide rail 606 is slidably disposed on the inner side of the spiral groove 603. The spiral guide rail 606 is fixedly disposed on the inner side of the protective shell 201. A gear bracket 6011 is rotatably disposed on the top of the power gear 601. The gear bracket 6011 is fixedly disposed on one side of the top end of the lifting frame 607. A receiving rod shell 608 is fixedly disposed at the bottom end of the lifting frame 607. A double-hole fixing plate 609 is provided, which is fixedly installed on the outside of the pH detection electrode rod 3. The lifting frame 607 and the double-hole fixing plate 609 are slidably installed on the outside of the vertical guide rail 205. A telescopic protective cover 8 is fixedly installed at the top of the pH detection electrode rod 3. The telescopic protective cover 8 is located on the outside of the spring wire and is fixedly installed at the bottom of the top cover 202. The telescopic protective cover 8 is installed through the lifting frame 607. A drive screw 701 is threaded through and connected to the top of the lifting frame 607. A drive device 7 is provided at one end of the drive screw 701. The drive screw 701 is fixedly installed at the drive end of the drive device 7. The drive screw 701 is rotatably installed at the top of the fixed frame 505. The drive device 7 is fixedly installed at the top of the top cover 202. The drive end of the drive device 7 is installed through and rotatably installed at the top of the top cover 202.

[0079] When the pH detection electrode rod 3 needs to be cleaned or stored, the drive screw 701 is driven to rotate by the drive device 7. The rotation of the drive screw 701 will cause the lifting frame 607 in the lifting mechanism 6 to rise. At the same time, the lifting frame 607 will drive the double hole plate 609 to rise, thereby driving the two pH detection electrode rods 3 into the protective shell 201. This not only allows for their storage, but also drives the cleaning mechanism 5 to clean the pH detection electrode rods 3.

[0080] When the pH detection electrode rod 3 is raised, the spring wire is compressed; when the pH detection electrode rod 3 is lowered, the spring wire is released, so that the spring wire can be extended or shortened to adapt to the height change of the pH detection electrode rod 3.

[0081] As the lifting frame 607 rises, it also lifts the fixed block 605, which in turn lifts the annular fixed rail 604 and the lifting spiral ring 602. Due to the setting of the spiral groove 603 and the spiral guide rail 606, the lifting spiral ring 602 will rotate simultaneously when it rises. The rotation of the lifting spiral ring 602 will drive the power gear 601 to rotate, and the rotation of the power gear 601 will drive the transmission rod 504 to rotate, thereby providing power to the cleaning mechanism 5 through the transmission rod 504.

[0082] See Figure 1 , Figure 2 and Figure 9 As shown, a cleaning pump 905 and an infusion pump 906 are symmetrically fixed at the top of the top cover 202. A first delivery pipe 902 is provided on one side of the cleaning pump 905, and a second delivery pipe 904 is provided on one side of the infusion pump 906. Two nozzles are provided at the other ends of the first delivery pipe 902 and the second delivery pipe 904. The nozzles are located above the water cover plate 507. A pipe connection bracket 903 is fixedly provided on the outside of the first delivery pipe 902 and the second delivery pipe 904. The pipe connection bracket 903 is fixedly provided on the outside of the double-hole fixed shell 506. A connecting pipe 901 is provided at the top of the cleaning pump 905 and the infusion pump 906. The connecting pipe 901 is inserted into the inside of the direct pipe 801. The detection controller 1 is electrically connected to the drive device 7, the cleaning pump 905 and the infusion pump 906.

[0083] In this embodiment, the driving device 7 includes a driving screw 701 and a driving motor 702.

[0084] A first delivery pipe 902 and a second delivery pipe 904 are respectively provided on the outside of the pH detection electrode rod 3, and the first delivery pipe 902 and the second delivery pipe 904 are arranged as a group for cleaning the pH detection electrode rod 3. When cleaning the pH detection electrode rod 3, the first delivery pipe 902 and the infusion pump 906 are started, and the cleaning solution and clean water are delivered through the connecting pipe 901. The connecting pipe 901 is inserted into the direct pipe 801, and the other end of the connecting pipe 901 is provided with a flexible tube. The flexible tube is located inside the protective shell 4 and is externally connected to the cleaning solution storage device and the clean water storage device. The device is designed to store the pH detection electrode rod 3. The cleaning pump 905 and the infusion pump 906 will not start simultaneously. During cleaning, the infusion pump 906 is started first to deliver the cleaning solution. While the pH detection electrode rod 3 retracts into the protective housing 201, the cleaning solution cleans the pH detection electrode rod 3. After the cleaning solution has cleaned the pH detection electrode rod 3, the pH detection electrode rod 3 extends out from inside the protective housing 201. At the same time, the cleaning pump 905 starts and draws clean water. The cleaning mechanism 5 cleans the pH detection electrode rod 3. After air drying, the pH detection electrode rod 3 can be used again for pH detection.

[0085] The working principle of this invention is as follows: When detecting the pH value of a liquid, the pH detection electrode rod 3 will come out from the inside of the protective shell 201. When the pH detection electrode rod 3 needs to be cleaned, the drive motor 702 is started. The drive motor 702 will drive the drive screw 701 to rotate. The rotation of the drive screw 701 will cause the lifting frame 607 in the lifting mechanism 6 to rise. At the same time, the lifting frame 607 will drive the double-hole fixed plate 609 to rise, thereby bringing the two pH detection electrode rods 3 into the protective shell 201. This not only allows for their storage but also drives the cleaning mechanism 5 to clean the pH detection electrode rods 3.

[0086] When the pH detection electrode rod 3 is raised, the spring wire is compressed; when the pH detection electrode rod 3 is lowered, the spring wire is released, allowing the spring wire to extend or shorten to adapt to changes in the height of the pH detection electrode rod 3.

[0087] As the lifting frame 607 rises, it also lifts the fixed block 605, which in turn lifts the annular fixed rail 604 and the lifting spiral ring 602. Due to the setting of the spiral groove 603 and the spiral guide rail 606, the lifting spiral ring 602 will rotate simultaneously when it rises. The rotation of the lifting spiral ring 602 will drive the power gear 601 to rotate, and the rotation of the power gear 601 will drive the transmission rod 504 to rotate, thereby providing power to the cleaning mechanism 5 through the transmission rod 504.

[0088] As the transmission rod 504 rotates, it drives the drive gear 501 to rotate as well. The rotation of the drive gear 501 then drives the linkage gear ring 5011 to rotate, which in turn drives the two cleaning gear rings 502 to rotate. The rotation of the cleaning gear rings 502 then drives the cleaning brush 503 to rotate. The cleaning brush 503 cleans the residual liquid on the outside of the pH detection electrode rod 3, achieving a rapid cleaning effect without the need for disassembly and installation, thus improving cleaning efficiency and consequently improving the detection efficiency of wastewater. The top of the water-passing cover 507 has multiple small holes for the passage of cleaning solution and clean water. The cleaning solution and clean water fall onto the cleaning brush 503 and are then used when cleaning the pH detection electrode rod 3.

[0089] Above each cleaning brush 503, a first delivery pipe 902 and a second delivery pipe 904 are installed. When cleaning the pH detection electrode rod 3, the first delivery pipe 902 and the infusion pump 906 are started, and the cleaning solution and clean water are delivered through the connecting pipe 901. The connecting pipe 901 is inserted into the direct pipe 801, and the other end of the connecting pipe 901 is equipped with a flexible tube. The flexible tube is located inside the protective shell 4 and is connected to the cleaning solution tank and the water tank. The cleaning pump 905 and the infusion pump 906 are not started at the same time. During cleaning, the infusion pump 906 is started first to deliver the cleaning solution. While the pH detection electrode rod 3 retracts into the protective shell 201, the cleaning solution cleans the pH detection electrode rod 3. After the cleaning solution has cleaned the pH detection electrode rod 3, the pH detection electrode rod 3 extends out from inside the protective shell 201. At the same time, the cleaning pump 905 is started and the cleaning pump 905 draws clean water. The cleaning mechanism 5 cleans the pH detection electrode rod 3. After air drying, the pH detection electrode rod 3 can be used again for pH detection.

[0090] In addition, the protective component 2 is designed to be detachable, which facilitates internal maintenance. The bottom connecting ring 203 makes the linkage gear ring 5011 more stable when rotating. The vertical guide rail 205 is used to stabilize the lifting mechanism 6. The spring wire will contract or lengthen as the pH detection electrode rod 3 rises and falls.

[0091] The pH meter online detection system of the present invention can be installed in a box, and the water storage device, cleaning solution storage device, cleaning pump 905 and infusion pump 906 involved can all be integrated inside the box.
