Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for water quality monitors, specifically relating to a water quality detector mounting bracket and cleaning device. Background Technology

[0002] When the pH glass electrode of the existing water quality monitor needs to be calibrated, the pipeline needs to be cut off in both directions, the pH glass electrode of the water quality detector in the pipeline needs to be removed, and the pipeline needs to be reconnected after the pH glass electrode is calibrated externally. Cutting off the pipeline and removing the pH glass electrode for calibration is inefficient, and cutting off and reconnecting the pipeline will affect the solution in the pipeline.

[0003] To address this, a water quality detector mounting bracket and cleaning device are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a water quality detector mounting bracket and cleaning device to solve the technical defects of inconvenient disassembly and calibration of existing pH glass electrodes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water quality detector mounting bracket and cleaning device includes a mounting assembly for connecting a pH glass electrode of the water quality detector and a cleaning assembly for cleaning the pH glass electrode.

[0007] The mounting assembly includes a first flange end, a second flange end, a ball valve core, and a rotating shaft. The first flange end and the second flange end are fixedly connected, forming a spherical cavity between them. The ball valve core is rotatably mounted within this cavity. The rotating shaft is rotatably mounted on the top of the second flange end, extending through the spherical cavity and connecting to the ball valve core. A pH glass electrode is longitudinally positioned within the rotating shaft, with its tip extending into the ball valve core along the front end of the shaft. The front end of the rotating shaft is open. Rotation of the rotating shaft coordinates with the rotation of the ball valve core, enabling the disconnection and connection of the pipeline.

[0008] The cleaning assembly includes a first ball valve, a second ball valve, a third ball valve, and a fourth ball valve. All four ball valves are fixedly installed on the outer side of the second flange end and are connected to the spherical cavity. By rotating the rotating shaft, the valve cores of the ball valves can be connected to the first, second, third, and fourth ball valves to facilitate the standard calibration and cleaning and drying of the pH glass electrode, thereby ensuring the stability of the pH glass electrode in use.

[0009] As a further embodiment of this invention, the pH glass electrode is threadedly installed inside the rotating shaft, with its rear end extending beyond the rear end of the rotating shaft. This threaded connection to the rotating shaft facilitates periodic replacement of the pH glass electrode, while the rear end of the pH glass electrode is used to connect to a water quality detector.

[0010] As a further embodiment of this utility model, the upper end of the second flange is integrally formed with an assembly seat, and a pressure plate is provided on the assembly seat. The rotating shaft passes through the assembly seat and the pressure plate to facilitate locking the rotating shaft.

[0011] As a further embodiment of this utility model, a limiting groove is reserved inside the connection between the mounting base and the second flange end, and a limiting block is fixedly installed on the outside of the rotating shaft. The limiting block is located in the limiting groove, and the lower end of the limiting block abuts against the upper arc of the ball valve core.

[0012] As a further embodiment of this utility model, a sealing ring is installed inside the mounting base. The inner ring surface of the sealing ring is tightly fitted with the outer surface of the rotating shaft. When the mounting components are locked, the pressure plate presses against the sealing ring.

[0013] As a further embodiment of this utility model, a positioning piece is fitted on the rotating shaft above the pressure plate, and a slot is provided on the outer side of the rotating shaft above the positioning piece. An outer retaining ring is engaged in the slot, and the positioning piece is pressed against the outer retaining ring and the pressure plate to ensure the sealing performance of the installation components.

[0014] As a further embodiment of this invention, several notches are reserved on the front wall of the rotating shaft, and the front end of the PH glass electrode is exposed inside the ball valve core through the notches, which facilitates the PH glass electrode to achieve all-round detection.

[0015] As a further embodiment of this utility model, an installation port for installing the first ball valve, the second ball valve, the third ball valve, and the fourth ball valve is fixedly installed on the outer side of the second flange end. This allows the detection liquid inside the ball valve core to be drained when the pH glass electrode needs to be calibrated, and the ball valve core and the rotating shaft containing the front end of the pH glass electrode to be cleaned with clean water. A standard solution is then introduced for calibration, followed by further cleaning with clean water and drying, ensuring that the solution inside the pipeline is not affected.

[0016] Compared with the prior art, the water quality detector mounting bracket and cleaning device provided by this utility model have the following beneficial effects: The mounting components of this utility model constitute a water quality detector mounting bracket for installing the pH glass electrode of the water quality detector, and the cleaning components are used for calibration assistance. Together with the mounting components, they can achieve the purpose of calibrating and cleaning the pH glass electrode of the water quality detector without disassembling the pipeline, which can greatly improve the calibration efficiency and avoid the problem of affecting the solution in the pipeline due to cutting off and restoring the pipeline.

[0029] See appendix Figure 1-6 As shown in the figure, an embodiment of the present invention provides a water quality detector mounting bracket and a cleaning device, including a mounting assembly for mounting a pH glass electrode 4 of the water quality detector and a cleaning assembly for cleaning the pH glass electrode 4 of the water quality detector.

[0030] The mounting assembly includes a first flange end 1 and a second flange end 2 that are connected front and rear, with a spherical cavity between the first flange end 1 and the second flange end 2. A ball valve core 9 is rotatably mounted in the spherical cavity between the first flange end 1 and the second flange end 2. A rotating shaft 3 is rotatably mounted on the top of the second flange end 2, with the front end of the rotating shaft 3 extending into the spherical cavity and fixedly connected to the ball valve core 9. The front end of the rotating shaft 3 also extends into the ball valve core 9. A pH glass electrode 4 is longitudinally inserted through and mounted in the rotating shaft 3, with the front end of the pH glass electrode 4 extending into the ball valve core 9 along the front end of the rotating shaft 3. The front end of the rotating shaft 3 is open to allow the pH glass electrode 4 to detect the pipeline.

[0031] The above-mentioned mounting components constitute a water quality detector mounting bracket, used to install the pH glass electrode 4 of the water quality detector.

[0032] The cleaning assembly includes a first ball valve 5, a second ball valve 6, a third ball valve 7, and a fourth ball valve 8. All four ball valves are fixedly installed on the outer side of the second flange end 2 and are connected to the spherical cavity. By operating the rotating shaft 3 to rotate the ball valve core 9, the channel of the ball valve core 9 can be connected to the first ball valve 5, the second ball valve 6, the third ball valve 7, and the fourth ball valve 8.

[0033] To facilitate connection of the device into the pipeline, flanges are integrally provided at the ends of the first flange end 1 and the second flange end 2 that are far apart from each other.

[0034] To facilitate assembly of the device, the first flange end 1 and the second flange end 2 are fixedly connected by bolts 10, and a sealing ring is provided between the first flange end 1 and the second flange end 2. The sealing ring can be made of silicone or rubber.

[0035] To facilitate the installation of the pH glass electrode 4, the pH glass electrode 4 is threaded into the rotating shaft 3. To facilitate the wiring of the pH glass electrode 4 with the water quality detector host, the rear end of the pH glass electrode 4 is located outside the rear end of the rotating shaft 3.

[0036] To facilitate the installation of the rotating shaft 3, the rotating shaft 3 is rotated through the mounting base 201 and the pressure plate 202. The mounting base 201 is fixedly installed on the outside of the second flange end 2, and the pressure plate 202 is fixedly installed on the mounting base 201 by screws 206.

[0037] To prevent the rotating shaft 3 from coming loose, a limiting groove 205 is reserved inside the connection between the mounting base 201 and the second flange end 2. At the same time, a limiting block 301 is provided outside the rotating shaft 3. The limiting block 301 rotates within the limiting groove 205, and the lower end of the limiting block 301 abuts against the upper arc of the ball valve core 9.

[0038] To improve the sealing between the rotating shaft 3 and the mounting base 201, a sealing ring 207 is provided inside the mounting base 201. The inner ring surface of the sealing ring 207 is tightly fitted with the outer surface of the rotating shaft 3. To prevent the sealing ring 207 from falling off, the pressure plate 202 presses against the sealing ring 207 when the screw 206 is tightened. The sealing ring 207 can be made of silicone or rubber.

[0039] To improve the stability between the rotating shaft 3 and the pressure plate 202, a positioning piece 203 is fitted on the rotating shaft 3 above the pressure plate 202. A slot is provided on the outer side of the rotating shaft 3 above the positioning piece 203, and an outer retaining ring 204 is engaged in the slot. The positioning piece 203 is pressed against the outer retaining ring 204 and the pressure plate 202.

[0040] To ensure that the front end of the pH glass electrode 4 can fully contact the liquid in the pipeline, several notches 302 are reserved on the front wall of the rotating shaft 3, so that the front end of the pH glass electrode 4 is exposed inside the ball valve core 9 through the notches 302.

[0041] To facilitate the installation of the first ball valve 5, the second ball valve 6, the third ball valve 7, and the fourth ball valve 8, four mounting ports 208 for installing the first ball valve 5, the second ball valve 6, the third ball valve 7, and the fourth ball valve 8 are fixedly installed on the outer side of the second flange end 2. Threads can be provided in the mounting ports 208 so that the first ball valve 5, the second ball valve 6, the third ball valve 7, and the fourth ball valve 8 can be easily screwed onto the mounting ports 208.

[0042] During installation, the rotating shaft 3 abuts against the ball valve core 9, the rotating shaft 3 passes through the mounting base 201, the sealing ring 207 is fitted onto the rotating shaft 3 and pushed into the mounting base 201, the pressure plate 202 is installed on the mounting base 201 using screws 206, and the screws 206 are tightened so that the pressure plate 202 presses against the sealing ring 207, when the positioning piece 203 is fitted onto the rotating shaft 3, the outer retaining ring 204 is inserted into the groove opened on the outer side of the rotating shaft 3, and the positioning piece 203 abuts against the outer retaining ring 204 and the pressure plate 202, the first flange End 1 and the second flange end 2 are connected by bolts 10, so that the ball valve core 9 is rotatably installed in the spherical cavity between the first flange end 1 and the second flange end 2. The first ball valve 5, the second ball valve 6, the third ball valve 7 and the fourth ball valve 8 are installed on the four mounting ports 208 on the outer side of the second flange end 2. Then, the flanges at the far ends of the first flange end 1 and the second flange end 2 are connected to the main pipeline. Finally, the pH glass electrode 4 is threaded into the rotating shaft 3, and the wire at the rear end of the pH glass electrode 4 is connected to the water quality detector host.

[0043] like Figure 3 As shown, it is worth noting that the rotating shaft 3 is set longitudinally for the convenience of subsequent calibration and cleaning.

[0044] Before calibration, operate the rotating shaft 3 to rotate the ball valve core 9 so that the channel of the ball valve core 9 is misaligned with the main pipeline, thereby cutting off the pipeline.

[0045] Open the fourth ball valve 8 located below the rotating shaft 3 to allow the residual liquid (the measured medium) in the ball valve core 9 to be discharged.

[0046] Open the second ball valve 5 and introduce cleaning fluid to clean the inside of the ball valve core 9 and the front end of the pH glass electrode 4. After cleaning, open the fourth ball valve 8 to drain the cleaning fluid.

[0047] Open the third ball valve 7 and introduce the standard solution to calibrate the pH glass electrode 4. After calibration, discharge the standard solution through the fourth ball valve 8.

[0048] Open the second ball valve 5 to allow cleaning fluid to flow in again to clean the inside of the ball valve core 9 and the front end of the pH glass electrode 4. After cleaning, open the fourth ball valve 8 to drain the cleaning fluid.

[0049] Open the first ball valve 6 and introduce compressed air to blow dry the inside of the ball valve core 9 and the front end of the PH glass electrode 4. At the same time, the gas is discharged through the opened fourth ball valve 8.

[0050] After calibration, manipulate the rotating shaft 3 to rotate the ball valve core 9, disconnecting the ball valve core 9 from the cleaning assembly, so that the ball valve core 9 is connected to the main pipeline, restoring the pipeline to form a passage, and continue real-time detection.

[0051] In summary, the cleaning component in the above-described technical solution of this utility model constitutes a cleaning device for a water quality detector, used to clean the pH glass electrode 4 of the water quality detector. Its installation components enable the calibration and cleaning of the pH glass electrode 4 of the water quality detector without disassembling the circuit, which can greatly improve the efficiency of calibrating and cleaning the detector, while avoiding the problem of affecting the solution in the pipeline due to cutting off and restoring the pipeline.
