Description

Technical Field

[0001] This utility model belongs to the field of urban water quality monitoring technology, and specifically relates to a water quality monitoring device for urban management water areas. Background Technology

[0002] In urban water supply networks, water quality monitoring is necessary to ensure the safety of urban water use. Existing water quality monitoring devices have the following technical problems during use: 1) Directly placing the testing instrument inside the pipe can easily damage the instrument under continuous impact due to the high pressure and fast flow rate of urban water supply pipes, affecting the final testing results; 2) Treated tap water may contain a small amount of solid impurities due to factors such as pipe aging and mechanical aging. Direct contact between the testing instrument and solid impurities will affect its testing accuracy.

[0003] A search revealed that prior art CN219715422U discloses a water quality monitoring device for a water supply network, including a monitoring probe installed inside the water pipe and a transmitter connected to the monitoring probe. A triangular prism baffle is installed inside the water pipe, with uniformly distributed through holes on its outer surface. When water flows into the baffle, it is diverted to the side of the baffle, with some water flowing through the through holes to contact the monitoring probe. This technical solution, through the triangular prism baffle, can effectively reduce the direct impact of water flow in the water supply network on the monitoring probe, extending the probe's lifespan. However, the following technical problems exist during use: 1) It cannot effectively block solid impurities; solid impurities not only clog the through holes on the baffle but also affect data acquisition if they come into contact with the monitoring probe; 2) It cannot perform real-time sampling and storage of the detected water flow, resulting in a limited functionality.

[0004] For example, the existing technology CN221883609U discloses a water quality monitoring auxiliary device, in which pipes are connected to both sides of the detection chamber, and an open area is opened through the middle of the top of the detection chamber. A monitoring mechanism is installed on the detection chamber and extends into the detection chamber through the open area. The monitoring mechanism is used to monitor the water source flowing in the detection chamber. The above technical solution uses the monitoring mechanism to monitor the sewage flowing in the detection chamber in real time, which can monitor the pollution status of the sewage in real time, which is convenient for subsequent targeted treatment of sewage. Moreover, the monitoring mechanism is easy to maintain and can be quickly removed from the detection chamber for maintenance. At the same time, with the assistance of the cleaning unit, the water quality tester is externally protected and can actively clean up the debris accumulated around it, which improves the accuracy of water quality monitoring. However, the above technical solution also has the following technical problems in use: 1) The solid impurities remaining in the treated water are generally small. The circular scraper can only move up and down on the cylindrical filter screen to scrape them. During the scraping process, solid impurities may even be pressed into the filter holes of the filter screen, resulting in poor cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water quality monitoring device for urban management water areas. By setting up a separate detection tube, the impact of water flow on the monitoring instrument is greatly reduced. At the same time, several pins are set on one side of the filter plate to clean the filter holes and to sample and store the water flow after testing, so as to meet the various requirements of technicians.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A water quality monitoring device for urban water management areas includes a water supply pipe, connecting flanges, a detection pipe, a filter plate, a conical rubber plug I, a needle, a guide rod, a waterproof electric telescopic rod I, a water quality monitor, an air inlet pipe, a one-way solenoid valve, a water outlet pipe, a diversion pipe, a return pipe, a connecting pipe, a waterproof electric telescopic rod II, a lifting frame, a turntable, a waterproof motor, a sampling bottle, a protective shell, a water inlet needle, and an air outlet needle. The water supply pipe has connecting flanges at both ends, which are connected to the urban water management network. A detection pipe is fixedly connected to the bottom of the water supply pipe. A filter plate is installed at the connection between the detection pipe and the water supply pipe. A conical rubber plug I is installed inside the detection pipe. One end of the conical rubber plug I has several needles, and the other end is fixedly connected to a guide rod. The guide rod moves through the sealing ring at the bottom of the detection pipe and then connects to the waterproof electric telescopic rod II. One end of the water-electric telescopic rod I is fixedly connected, and the other end of the waterproof electric telescopic rod I is fixedly installed on the bottom plate of the detection tube. A water quality monitor is installed on one side of the detection tube. The water quality monitor model is PH-6001, which can be obtained through private customization or direct purchase. One side of the detection tube is fixedly connected to the air inlet pipe, which is equipped with a one-way solenoid valve. The bottom of the detection tube is connected to the diversion pipe through the water outlet pipe. One end of the diversion pipe is fixedly connected to the water supply pipe through the return pipe, and the other end is connected to the water inlet needle through the connecting pipe. An air outlet needle is fixedly installed on one side of the water inlet needle. A protective shell is installed on the outside of the detection tube. The protective shell is fixedly installed on the water supply pipe. A waterproof motor is fixedly installed at the bottom of the protective shell. A turntable is fixedly connected to the output end of the waterproof motor. The turntable is movably installed inside the protective shell. Several sampling bottles are placed between the turntable and the protective shell.

[0008] A lifting frame is movably installed inside the inner wall of one side of the protective shell. One end of the waterproof electric telescopic rod II is fixedly connected to one side of the lifting frame, and the other end of the waterproof electric telescopic rod II is fixedly installed on the protective shell.

[0009] The detection tube is tapered on the side near the water pipe, which improves the sealing effect of the tapered rubber stopper I.

[0010] The diversion tube is equipped with a movable ring. The inner ring of the movable ring is elliptical, and tapered rubber plugs II are fixedly installed at both ends of the outer side. A main shaft is provided inside the elliptical inner ring of the movable ring. A protrusion is fixedly installed on the main shaft. Both ends of the main shaft are movably installed on the side wall of the diversion tube. A gear is fixedly connected to one end of the main shaft. The gear meshes with a rack and is movably connected. The rack is movably installed on the outside of the diversion tube. One end of the rack is fixedly connected to one end of a waterproof electric telescopic rod III. The other end of the waterproof electric telescopic rod III is fixedly installed on the diversion tube.

[0011] The protective shell has a movable door on one side, which facilitates the placement and removal of the sampling bottle.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1) When water quality testing is required, adjust the waterproof electric telescopic rod I to extend, so that the guide rod drives the conical rubber plug I and its head pin to detach from the filter plate and the inner wall of the test tube, so that the water flows through the filter plate and enters the test tube. Then adjust the waterproof electric telescopic rod I to retract, so that the conical rubber plug I fits into the test tube to complete the seal, and its head pin can clean the filter plate pores, push out impurities and wash them away by the water flow, effectively avoiding filter pore blockage and improving cleaning efficiency;

[0014] 2) By adjusting the waterproof electric telescopic rod III, the rack and pinion mesh with the gear, causing the main shaft to rotate. This causes the convex block on the main shaft to rotate within the inner circle of the movable ring ellipse. When the convex block rotates from the small end to the large end of the inner circle of the ellipse, it will compress the spring telescopic rod on the same side. The extension of the spring telescopic rod on the other side is much less than the compression. At this time, the conical rubber plug II on one side can be controlled to close, while the other side remains open. Thus, the conical rubber plugs II at both ends can be controlled to close the return pipe or the connecting pipe as needed, achieving the purpose of diversion control. This enables multiple operations such as return or sampling, making it more adaptable.

[0015] 3) During sampling, the waterproof motor drives the turntable to rotate the sampling bottle into the lifting frame. Then, the waterproof electric telescopic rod II drives the lifting frame to lift, so that the water inlet needle and air outlet needle pass through the rubber stopper at the mouth of the sampling bottle. At this time, the high pressure can be maintained by controlling the flow divider and inflating the air inlet pipe, which can force the liquid in the test tube into the sampling bottle. By adding the air outlet needle, the pressure inside and outside the sampling bottle is kept constant, which effectively prevents the rubber stopper from dislodging. Attached Figure Description

The connecting plate is fixedly connected to one end of the waterproof electric telescopic rod I17, and the other end of the waterproof electric telescopic rod I17 is fixedly installed on the base plate of the detection tube 12. A water quality monitor 18 is installed on one side of the detection tube 12. The water quality monitor 18 is model PH-6001 and can be obtained through private customization or direct purchase. An air inlet pipe 19 is fixedly connected to one side of the detection tube 12. A one-way solenoid valve 20 is installed on the air inlet pipe 19. The bottom of the detection tube 12 is connected to the diversion pipe 22 through the water outlet pipe 21. One end of the diversion pipe 22 is connected to the return pipe 22 through the return pipe 21. The flow tube 23 is fixedly connected to the water supply pipe 10, and the other end is connected to the water inlet needle 241 through the connecting pipe 24. An air outlet needle 242 is fixed on one side of the water inlet needle 241. A protective shell 30 is provided on the outside of the detection tube 12. The protective shell 30 is fixedly installed on the water supply pipe 10. A waterproof motor 28 is fixedly installed at the bottom of the protective shell 30. A turntable 27 is fixedly connected to the output end of the waterproof motor 28. The turntable 27 is movably installed inside the protective shell 30. Several sampling bottles 29 are provided between the turntable 27 and the protective shell 30.

[0024] A lifting frame 26 is movably installed inside the inner wall of one side of the protective shell 30. One end of the waterproof electric telescopic rod II 25 is fixedly connected to one side of the lifting frame 26, and the other end of the waterproof electric telescopic rod II 25 is fixedly installed on the protective shell 30.

[0025] The detection tube 12 has a conical shape on the side near the water supply pipe 10, which can improve the sealing effect of the conical rubber stopper I14.

[0026] The diversion pipe 22 is provided with a movable ring 221. The inner ring of the movable ring 221 is elliptical. Spring telescopic rods 228 are fixedly installed at both ends of the outer side of the movable ring 221. A conical rubber plug II 222 is installed at the other end of the spring telescopic rods 228. A main shaft 223 is provided inside the elliptical inner ring of the movable ring 221. A protrusion 224 is fixedly installed on the main shaft 223. Both ends of the main shaft 223 are movably installed on the side wall of the diversion pipe 22. A gear 225 is fixedly connected to one end of the main shaft 223. The gear 225 is meshed and movably connected with a rack 226. The rack 226 is movably installed on the outer side of the diversion pipe 22. A waterproof electric telescopic rod III 227 is fixedly connected to one end of the rack 226. One end of the waterproof electric telescopic rod Ⅲ227 is fixedly installed on the diversion pipe 22. By adjusting the waterproof electric telescopic rod Ⅲ227, the rack 226 and gear 225 are driven to mesh and transmit power, so that the main shaft 223 rotates. This causes the protrusion 224 on the main shaft 223 to rotate in the inner circle of the ellipse of the movable ring 221. When the protrusion 224 rotates from the small end to the large end of the inner circle of the ellipse, it will compress the spring telescopic rod 228 on the same side. The extension of the spring telescopic rod 228 on the other side is much less than the compression. At this time, the conical rubber plug Ⅱ222 on one side can be closed and the other side can be connected. Thus, the conical rubber plugs Ⅱ222 on both ends can be controlled to close the return pipe 23 or the connecting pipe 24 as needed.

[0027] The protective shell 30 has a movable door 301 on one side, which facilitates the placement and removal of the sampling bottle 29.

[0028] A water quality monitoring device for urban water management areas operates as follows: First, the water supply pipe 10 is fixedly installed on the urban water pipeline network to be monitored via the connecting flange 11, with the shear head pointing in the same direction as the water flow, and ensuring that the shear head on the protective shell 30 points towards the ground. At this time, the water to be monitored will flow through the water supply pipe 10. Then, when the water quality is tested, the device is connected to an external power source, and the waterproof electric telescopic rod I17 is extended, causing the guide rod 16 to drive the conical rubber plug I14 and its head pin 15 to detach from the filter plate 13 and the inner wall of the detection tube 12, so that the water flows through the filter plate 13 and enters the detection tube 12. Subsequently, the waterproof electric telescopic rod I17 is retracted, so that the conical rubber plug I14 fits the detection tube 12 to complete the seal, and its head pin 15 can clean the filter holes of the filter plate 13, push out the impurities in the filter holes, and use the water flow to flush them away.

[0029] After the water quality monitor 18 completes the water quality analysis, the air inlet pipe 19 connects to the air tank, forcing gas into the detection tube 12 and forcing the liquid in the detection tube 12 into the diversion pipe 22. The liquid can then flow back to the water supply pipe 10 through the diversion pipe 22 and the return pipe 23. Alternatively, the lifting frame 26 can be retracted via the waterproof electric telescopic rod II 25, thereby raising the sampling bottle 29. This allows the water inlet needle 241 to be inserted into the rubber stopper at the head of the sampling bottle 29, after which water flows into the water inlet through the connecting pipe 24. The needle 241 is inserted into the sampling bottle 29, and the gas inside is discharged through the vent needle 242, thus preventing the rubber stopper from coming off. After sampling or reflux is completed, the protrusion 224 in the diverter tube 22 rotates with the main shaft 223 to the small end of the elliptical inner ring of the movable ring 221. At this time, the movable ring 221 is reset, and the spring telescopic rods 228 at both ends will apply elastic force to the conical rubber stopper II 222, thereby sealing the reflux tube 23 and the connecting tube 24, ready for the next use.

[0030] In summary, the electronic or electrical components, including but not limited to waterproof electric telescopic pole I, water quality monitor, waterproof electric telescopic pole II, waterproof motor, and waterproof electric telescopic pole III, are existing components that were custom-made or purchased. They are powered by an external power source, and the electrical connections between these components are conventional circuit or electrical connections found in existing technologies.
