Technical Field

[0001] This utility model belongs to the technical field of oxygen measuring equipment accessories, and in particular relates to an oxygen measuring device mounting base. Background Technology

[0002] In the field of water quality monitoring, dissolved oxygen content is one of the key indicators for measuring water quality. Accurate measurement of dissolved oxygen in water is crucial for industries such as industrial production, environmental monitoring, and aquaculture. This makes dissolved oxygen detectors an indispensable piece of equipment, and the mounting base, as a key component, plays a decisive role in the accuracy of measurement results and the stability of the equipment.

[0003] Existing mounting bases use simple bolt connections or snap-fit ​​fixing methods, which makes it easy for the mounting base and stainless steel round tube to loosen under water flow impact, equipment vibration and other conditions, making it impossible to firmly fix the support frame. This leads to instability in the operation of the entire cleaning device and oxygen measuring device. In some corrosive water environments, the components of the mounting base may be made of ordinary materials, which are easily corroded, reducing the structural strength and service life of the mounting base, and thus affecting the reliability of the oxygen measuring device.

[0004] In other words, the existing mounting bases are difficult to provide stable support under complex working conditions and are susceptible to corrosion. This not only fails to ensure the stable operation of the oxygen measurement device but also shortens its own service life, making it difficult to meet the growing demand for accurate water quality monitoring in industries such as industrial production, environmental monitoring, and aquaculture. Utility Model Content

[0020] like Figures 1 to 3 As shown, this utility model provides an oxygen measuring device mounting base, which includes a perforated blind plate 1, an internal thread 2, a clamping coupling 3, a stainless steel round pipe 4, an internal thread 5, a perforated pipe cap 6, and a manual butterfly valve 7. The perforated blind plate 1 provides a mounting base for the internal thread 2. The internal thread 2 is connected to the perforated blind plate 1 for connecting the oxygen measuring device. The clamping coupling 3 is connected to the perforated blind plate 1. The stainless steel round pipe 4 is connected to the clamping coupling 3 for providing flow space for the medium. The internal thread 5 is connected to the stainless steel round pipe 4 for connecting an external pipe. There are two internal threads 5, one for the medium outlet and one for the medium inlet. The perforated pipe cap 6 is connected to the stainless steel round pipe 4 for installing the manual butterfly valve 7. The manual butterfly valve 7 is connected to the perforated pipe cap 6 for adjusting the flow rate of the medium in the stainless steel round pipe 4. An air drain valve is connected to the bottom of the manual butterfly valve 7.

[0021] The flow rate of the medium inside the stainless steel round tube 4 of the manual butterfly valve 7 creates a stable and suitable measurement environment for the oxygen measuring device. The oxygen measuring device is connected by internal thread 1 2 and the external connecting pipe is connected by internal thread 2 5, which facilitates the assembly, disassembly and maintenance of the device, greatly reducing the difficulty of installation and operation and maintenance, and improving work efficiency. The stainless steel round tube 4 has good resistance to chloride corrosion, which solves the problem of easy aging and corrosion of the mounting base material, which affects the service life and performance.

[0022] In use, the oxygen measuring device is installed to the inner thread 2 by rotation. Then, the stainless steel round pipe 4 is connected to the perforated blind plate 1 using the clamp coupling 3, creating a channel for media flow. One end of one of the inner threads 5 is then connected to a connecting pipe or other media source. The vent valve is then activated to release the gas inside the stainless steel round pipe 4, filling it with media. Once media delivery begins, the media flows into the stainless steel round pipe 4 from the media inlet. As the media flows through the oxygen measuring device, the device monitors the oxygen content in the water in real time. The water continues to flow through the round pipe after the monitoring is completed. The water flows out from the inner thread 25, which serves as the medium outlet, completing one measurement cycle. During this process, if the water flow rate is too fast, it may lead to insufficient measurement by the oxygen measuring device. In this case, the butterfly valve opening can be reduced to slow down the medium flow rate. If the flow rate is too slow and affects the detection efficiency, the butterfly valve opening can be increased to speed up the water flow rate, thereby creating a stable and suitable measurement environment for the oxygen measuring device and ensuring the accuracy of the measurement data. After completing one water quality monitoring task, stop the medium delivery and the oxygen measuring device, and then open the drain valve to drain the remaining water in the pipeline to prevent liquid residue from damaging the pipeline and the oxygen measuring device.

[0023] Specifically, the diameter of the perforated blind flange 1 is φ88.9, the size of the clamp union 3 is φ88.9, the diameter of the stainless steel round pipe 4 is φ88.9, the specification of the manual butterfly valve 7 is φ19.1, the specification of the inner thread 1 2 is 1, the specification of the inner thread 2 5 is 1 / 2, the perforated blind flange 1 is connected to the stainless steel round pipe 4 through the clamp union 3, the inner thread 1 2 and the inner thread 2 5 are both provided with threaded grooves inside, the top of the inner thread 1 2 is threaded to an oxygen measuring device, one end of the inner thread 2 5 is connected to a connecting pipe for conveying the medium, the inner thread 2 5, the perforated blind flange 1 and the perforated cap are all connected to the stainless steel round pipe 4 through, the manual butterfly valve 7 is connected to the perforated cap through, and the bottom of the manual butterfly valve 7 is connected to an external vent valve for venting the gas in the stainless steel round pipe 4.

[0024] In this embodiment, one of them is located at the bottom of the outer surface of the stainless steel round tube 4, which is the medium inlet, and the other is located at the top of the outer surface of the stainless steel round tube 4, which is the medium outlet.

[0025] See Figure 2 and Figure 3In this embodiment, a cleaning device is also included. The cleaning device includes a fixed base 8, a support frame 9, a drive shaft 10, a floating column 11, and a drive disk 12. The fixed base 8 is connected to the stainless steel round tube 4 and is used to fix the support frame 9. The drive shaft 10 is connected to the support frame 9, and the support frame 9 is inserted into the fixed base 8. The drive disk 12 and the floating column 11 are sleeved on the drive shaft 10. The floating column is used to drive the drive disk 12 to move back and forth in a first direction. The drive shaft 10 is provided with a limiting sleeve 13 to restrict the movement of the drive disk 12. The drive disk 12 is provided with blades 14, which drive the drive disk 12 to rotate around the drive shaft 10 through the flow of the medium. The drive disk 12 is provided with a cleaning brush 15, and the cleaning brush 15 is attached to the inner wall of the stainless steel round tube 4 to clean the inner wall of the stainless steel round tube 4. The drive disk 12 is made of aluminum alloy, which has low density and is corrosion resistant.

[0026] The blades 14, under the action of the medium flow, drive the drive disk 12 to rotate stably around the drive shaft 10. At the same time, the buoyancy of the medium inside the stainless steel tube causes the floating column 11 to drive the drive disk 12 to move back and forth in the first direction, thereby causing the cleaning brush 15 connected to the drive disk 12 to rotate accordingly. This effectively removes dirt, impurities, and biofilms attached to the tube wall, preventing them from affecting the accuracy of the oxygen measuring device and ensuring the reliability of the measurement data.

[0027] In use, first open the drain valve to drain the medium from the stainless steel round tube 4. At this time, the drive disc 12 is at the lower end of the drive shaft 10. When the test begins, the medium flows into the stainless steel round tube 4 from the medium inlet. As the medium continues to enter, the floating column 11, being submerged in the medium, will be subject to the buoyancy of the medium. This buoyancy will drive the floating column 11 and the drive disc 12 connected to it to move upward along the drive shaft 10. At the same time, the medium flows inside the round tube, and the blades 14 on the drive disc 12 are impacted by the water flow. Under the action of the water flow, the blades 14 drive the drive disc 12 to rotate around the drive shaft 10. The cleaning brush 15 connected to the drive disc 12 rotates with the drive disc 12. The moving and rising motion continuously contacts and rubs against the inner wall of the stainless steel round tube 4, thereby cleaning the inner wall and removing attached dirt and impurities. When a measurement cycle ends, the drain valve is opened or the medium is discharged through the medium outlet. As the medium is gradually discharged, the buoyancy of the floating column 11 decreases, and the drive disc 12, under its own weight and driven by the floating column 11, falls back down along the drive shaft 10, eventually returning to the lower end of the drive shaft 10. In this way, during each process of medium inflow and outflow, the drive disc 12 will perform the actions of rising, rotating for cleaning, and falling back in a cycle, continuously cleaning the inner wall of the stainless steel round tube 4, ensuring the cleanliness of the measurement environment of the oxygen measuring device, and improving the measurement accuracy.

[0028] Specifically, the fixing seat 8 is fixedly installed on the inner wall of the stainless steel round tube 4, and the support frame 9 is movably connected to the fixing seat 8. The cleaning brush 15 can be made of Teflon. Teflon has high chemical stability, is corrosion resistant, and has a smooth surface, which avoids scratching the inner wall of the stainless steel round tube 4.

[0029] Working Principle: In use, the oxygen measuring device is threaded onto the inner thread 2. Then, the stainless steel round pipe 4 is connected to the perforated blind plate 1 using the clamp coupling 3, creating a medium flow channel. Next, one of the inner threads 5 is connected to the medium inlet via an external connecting pipe or other medium source. Then, the drain valve is activated. At this time, the drive disc 12 is at the lower end of the drive shaft 10. When the medium begins to flow, it enters the stainless steel round pipe 4 from the medium inlet. As the medium flows through the round pipe, the oxygen measuring device detects the oxygen content in the water in real time. The detected water continues to flow within the round pipe and finally exits from the inner thread 2, which serves as the medium outlet. As the second filament (5) flows out, completing one measurement cycle, the floating column 11, immersed in the medium, experiences buoyancy. This buoyancy causes the floating column 11 and its connected drive disc 12 to move upward along the drive shaft 10. Simultaneously, as the medium flows within the circular tube, the blades 14 on the drive disc 12 are impacted by the water flow. Under the dynamic force of the water flow, the blades 14 drive the drive disc 12 to rotate around the drive shaft 10. The cleaning brush 15, connected to the drive disc 12, continuously contacts and rubs against the inner wall of the stainless steel circular tube 4 as the drive disc 12 rotates and rises, thus cleaning the inner wall. Cleaning is performed to remove attached dirt and impurities. During this process, if the water flow rate is too fast, it may lead to insufficient measurement by the oxygen measuring device. In this case, the butterfly valve opening can be reduced to slow down the medium flow rate. If the flow rate is too slow and affects the detection efficiency, the butterfly valve opening can be increased to speed up the water flow rate, thereby creating a stable and suitable measurement environment for the oxygen measuring device and ensuring the accuracy of the measurement data. After completing a water quality monitoring task, stop the medium delivery and the oxygen measuring device, and then open the drain valve to drain the remaining water in the pipeline to prevent liquid residue from damaging the pipeline and the oxygen measuring device. During this process, as the medium is gradually discharged, the buoyancy of the floating column 11 decreases. Driven by its own gravity and the floating column 11, the drive disc 12 falls downward along the drive shaft 10 and eventually returns to the lower end of the drive shaft 10. During each flow of medium in and out, the drive disc 12 will cycle through rising, rotating for cleaning and falling back, continuously cleaning the inner wall of the stainless steel round tube 4, ensuring the cleanliness of the oxygen measuring device's measurement environment and improving measurement accuracy. When the cleaning brush 15 needs to be replaced, the stainless steel round tube 4 is separated from the perforated blind plate 1 by opening the clamp joint 3. At this time, the support frame 9 is separated from the fixed seat 8 by rotating the drive shaft 10, which facilitates the replacement of the cleaning device.
