Description

Technical Field

[0001] This invention belongs to the technical field of pressure and flow detection devices, specifically a pressure and flow detection device for tap water pipe networks. Background Technology

[0002] Urban water supply networks are the "lifeline" for ensuring residents' water supply, and pressure and flow detection are core components of intelligent operation and maintenance of these networks. Ultrasonic flow meters, due to their non-invasive nature and strong adaptability, have become the mainstream equipment in this scenario. Ultrasonic flow meters measure flow based on the "speed difference of sound waves propagating in fluids." The core principle is to infer the water flow velocity from the "time difference of sound wave propagation with or against the flow," and then combine this with the pipe cross-sectional area to calculate the flow rate.

[0003] The clamp-on ultrasonic flow meter mainly consists of a sensor unit, a main unit, a connection unit, and installation accessories. When using the clamp-on ultrasonic flow meter, first apply coupling agent to the sensor of the clamp-on ultrasonic flow meter, and then install and test the clamp-on ultrasonic flow meter with the tap water pipe.

[0004] Applying coupling agent to the emitting surface of the sensor in a clamp-on ultrasonic flow meter is for more accurate detection of water pipes. Since water pipes are mostly exposed, their surfaces often contain impurities. If these impurities are not cleaned promptly when using a clamp-on ultrasonic flow meter, it will affect the accuracy of subsequent measurements. Furthermore, most cleaning components need to be carried separately, which is inconvenient. Additionally, the application of coupling agent relies heavily on manual labor, and the evenness of application depends on the operator's experience. Inexperienced operators may apply the agent unevenly, affecting the accuracy of the measurements.

[0005] Therefore, the present invention provides a device for detecting the pressure and flow rate of a tap water network. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: A water supply network pressure and flow detection device according to the present invention includes an ultrasonic flow meter; it further includes: a connecting mechanism, comprising two symmetrically fixedly mounted connecting frames on the ultrasonic flow meter, wherein a plurality of first elastic balls are fixedly mounted inside the connecting frames, a sliding movable clamp plate inside the connecting frames is fixedly connected to the plurality of first elastic balls, and a downwardly inclined connecting pipe is fixedly mounted on one side of the plurality of first elastic balls; bolts and threaded holes are respectively provided inside the two movable clamp plates; and a coating mechanism, comprising a storage frame connected to the top of the ultrasonic flow meter via a sliding mechanism, wherein a support plate for supporting a liquid storage box is fixedly mounted inside the storage frame, an outlet pipe connected to the inside and equipped with a one-way valve is fixedly mounted on one side of the liquid storage box, an inlet pipe connected to the inside and equipped with a one-way valve is fixedly mounted on one side of the liquid storage box, and a first multi-stage telescopic pipe is fixedly mounted inside the storage frame, the first multi-stage telescopic pipe being composed of a plurality of hollow round pipes slidably connected, and the first multi-stage telescopic pipe being connected to the outlet pipe, and a brush plate being provided on one side of the first multi-stage telescopic pipe.

[0008] Furthermore, the application mechanism also includes a blocking component, which includes a slide rod slidably connected to an elastic rope and a support plate. A first magnetic block is fixedly installed on one side of the slide rod, and a second magnetic block is fixedly installed on one side of the first multi-stage telescopic tube.

[0009] Furthermore, the coating mechanism also includes a diffusion component, which includes a hollow frame fixedly connected to the first multi-stage telescopic tube. One side of the hollow frame has several liquid outlet holes that communicate with the interior, and the brush plate is fixedly installed on the top of the hollow frame.

[0010] Furthermore, the sliding mechanism includes a groove formed on the top of the ultrasonic flow meter, a slider that is fixedly connected to the storage frame is slidably connected inside the groove, and gaskets are fixedly installed on both sides of the slider.

[0011] Furthermore, the storage frame is provided with a squeezing mechanism, which includes a fixed frame fixedly installed inside the storage frame, and a squeezing block is slidably connected inside the fixed frame; several round tubes inside the first multi-stage telescopic tube are slidably connected in a sealed manner, and the several round tubes are connected to each other through several through holes; the fixed frame and the first multi-stage telescopic tube are connected through an air guide pipe.

[0012] Furthermore, two symmetrically arranged, arc-shaped auxiliary plates are fixedly installed at the bottom of the extrusion block, and a rolling column is rotatably connected to one side of each auxiliary plate.

[0013] Furthermore, a scraping mechanism is provided within the connecting frame. The scraping mechanism includes several second elastic balls fixedly installed within the connecting frame and fixedly connected to the movable clamping plate. A second multi-stage telescopic tube is fixedly installed on one side of the movable clamping plate. The second multi-stage telescopic tube is composed of several hollow round tubes that are sealed and slidably connected, and the round tubes are connected to each other through several through holes. The second multi-stage telescopic tube and the several second elastic balls are connected through a connecting pipe. A rotating rod is rotatably connected to the bottom of the second multi-stage telescopic tube. A scraper is fixedly installed at one end of the rotating rod, and a cleaning plate with a cleaning cloth is fixedly installed on the scraper through several support rods.

[0014] Furthermore, a spraying mechanism is provided at the bottom of the second multi-stage telescopic tube. The spraying mechanism includes a cavity opened inside the second multi-stage telescopic tube. A rubber box is fixedly installed inside the cavity. A pipe with a one-way valve is fixedly installed on one side of the rubber box. A guide pipe with a one-way valve is fixedly installed on another side of the rubber box. A fixing plate is fixedly installed on the surface of the rotating rod.

[0015] Furthermore, the ultrasonic flow meter is provided with a storage mechanism at its bottom. The storage mechanism includes a storage box located at the bottom of the ultrasonic flow meter. The storage box is connected to the storage frame by a fixing rod, and an arc-shaped flow guide block is fixedly installed inside the storage box.

[0016] Furthermore, several protrusions are fixedly installed inside the groove.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The water supply network pressure and flow detection device of this invention uses two movable clamps to reset, thereby clamping the water supply pipe and facilitating subsequent contact between the ultrasonic flow meter and the water supply pipe for pressure and flow detection. By pulling the first multi-stage telescopic tube, the coupling agent in the storage box can enter the hollow frame through the outlet pipe, and then flow to the back of the ultrasonic flow meter through several outlet holes in the hollow frame. The movement of the hollow frame, along with the brush plate, evenly brushes the outflowing coupling agent. Through the designed structure, rapid cleaning of the detection area of ​​the water supply pipe is achieved, while integrating the cleaning structure with the clamping structure, achieving convenience and eliminating the need for personnel to carry additional cleaning tools. Pre-cleaning also improves the detection accuracy of the ultrasonic flow meter. Furthermore, the coupling agent is integrated into the storage frame of the ultrasonic flow meter, allowing for even application of the coupling agent to the ultrasonic flow meter with a simple up-and-down movement, eliminating the need for long-term experience of personnel to achieve even application. Finally, the outlet pipe can be automatically closed when the coupling agent is not in use. This allows the equipment to be integrated without the need to carry additional tools and parts such as coupling agents.

[0019] 2. In the water supply network pressure and flow detection device of the present invention, when the first multi-stage telescopic tube is pulled down, the gas in the fixed frame is drawn away through the air guide pipe. The gas enters the first multi-stage telescopic tube through the air guide pipe and enters several circular tubes through several through holes in the first multi-stage telescopic tube. At this time, the extrusion block, along with the auxiliary plate and the rolling column, moves towards the deformable liquid storage box. The extrusion block and other components assist in extruding the liquid storage box, thereby accelerating the flow of the coupling agent and preventing the ultrasonic flow meter from being unable to be fully coated with the required coupling agent due to the slow flow rate of the coupling agent. When the first multi-stage telescopic tube resets, the gas is reintroduced into the fixed frame through the air guide pipe, thereby resetting the extrusion block and other components and no longer applying pressure to the liquid storage box, thus reducing the outflow of coupling agent.

[0020] 3. In the water supply network pressure and flow detection device of this invention, the second multi-stage telescopic tube moves downwards along with the scraper and cleaning plate via a rotating rod, thus assisting in cleaning the ultrasonic flow meter and facilitating the subsequent application of coupling agent to the ultrasonic flow meter. When the moving clamp resets, the gas inside the second multi-stage telescopic tube returns to the second elastic ball through the connecting pipe, and the scraper and cleaning plate also reset accordingly. After completing the above operations, the rotating rod rotates the scraper and cleaning cloth away from the ultrasonic flow meter, ensuring that the scraper and other components do not affect the subsequent application of coupling agent. This design allows for the sliding clamping action of the moving clamp to first complete the auxiliary cleaning of the water supply pipe, facilitating the subsequent detection of the water supply pipe by the ultrasonic flow meter. Simultaneously, during disassembly, the sliding of the moving clamp again cleans the coupling agent used on the ultrasonic flow meter, eliminating the need for separate cleaning of the coupling agent and preventing the mixing of residual coupling agent from affecting detection accuracy.

[0021] 4. The water supply network pressure and flow detection device of this invention, by installing a collection box at the bottom of the ultrasonic flow meter and using a fixing rod to move the collection box and the collection frame synchronously, allows excess coupling agent to fall when sprayed out, which is then collected and stored in the collection box. When the rubber box is sprayed with liquid-assisted scraper to remove the coupling agent, the collection box also serves to collect and store it, thus reducing the need for cleaning up spilled materials. The arc-shaped guide block is designed to guide the collected coupling agent and other substances deep into the collection box, preventing them from accumulating in one place and overflowing. When the collection frame slides back to its original position via the slider, it contacts the protrusion and vibrates, causing the coupling agent inside the collection box to vibrate, thereby accelerating the flow of the coupling agent and ensuring it is evenly stored within the collection box, improving its utilization rate. Simultaneously, after the collection box returns to its original position with the collection frame, the bottom of the ultrasonic flow meter seals the top of the collection box, preventing the coupling agent inside from leaking out when the collection box is being carried.

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] like Figures 1 to 11 As shown in the embodiment of the present invention, a water supply network pressure and flow detection device includes an ultrasonic flow meter 1; it also includes: a connecting mechanism 10, comprising two symmetrically fixedly mounted connecting frames 11 on the ultrasonic flow meter 1, a plurality of first elastic balls 12 fixedly mounted inside the connecting frames 11, a sliding movable clamping plate 13 inside the connecting frames 11 fixedly connected to the plurality of first elastic balls 12, and an inclined downward connecting pipe 16 fixedly mounted on one side of the plurality of first elastic balls 12, and bolts 14 and threaded holes 15 respectively provided inside the two movable clamping plates 13; and a coating mechanism 20, comprising a coating mechanism for the ultrasonic flow meter 1. The top of the container 1 is connected to a storage frame 21 via a sliding mechanism 30. Inside the storage frame 21, a support plate 22 is fixedly installed to support the liquid storage box 23. One side of the liquid storage box 23 is fixedly installed with an outlet pipe 24 that communicates with the interior and has a one-way valve. Another side of the liquid storage box 23 is fixedly installed with an inlet pipe that communicates with the interior and has a one-way valve. Inside the storage frame 21, a first multi-stage telescopic tube 25 is fixedly installed. The first multi-stage telescopic tube 25 is composed of several hollow round tubes that are slidably connected. The first multi-stage telescopic tube 25 is connected to the outlet pipe 24, and a brush plate 26 is provided on one side of the first multi-stage telescopic tube 25.

[0046] Specifically, the application mechanism 20 also includes a blocking component 27, which includes a slide rod 271 slidably connected to the support plate 22 via an elastic rope. A first magnetic block 272 is fixedly installed on one side of the slide rod 271, and a second magnetic block 273 is fixedly installed on one side of the first multi-stage telescopic tube 25. The application mechanism 20 also includes a diffusion component 28, which includes a hollow frame 281 fixedly connected to the first multi-stage telescopic tube 25. One side of the hollow frame 281 has several liquid outlet holes 282 communicating with the interior, and a brush plate 26 is fixedly installed on the top of the hollow frame 281.

[0047] Specifically, the sliding mechanism 30 includes a groove 31 opened on the top of the ultrasonic flow meter 1, and a slider 32 fixedly connected to the storage frame 21 is slidably connected inside the groove 31. Gaskets 33 are fixedly installed on both sides of the slider 32.

[0048] When using the ultrasonic flow meter 1 to detect the pressure and flow rate of a tap water pipe, first bring the ultrasonic flow meter 1 close to the tap water pipe. Slide the movable clamps 13 within the two connecting frames 11, causing them to slide away from each other. As the movable clamps 13 slide, they cause the first elastic ball 12 to expand (initially, the first elastic ball 12 is compressed and deflated), thereby drawing external air into the first elastic ball 12 through the connecting pipe 16. This operation increases the gap between the two movable clamps 13, making it easier to position the tap water pipe between them. After completing the above operations, release the two movable clamps 13, allowing several first elastic balls 12 to reset along with the movable clamps 13, thereby allowing the two movable clamps 13 to clamp the water pipe. It should be noted that at this time, the two movable clamps 13 do not completely clamp and fix the water pipe, and when the several first elastic balls 12 reset, they will blow the internal gas through the connecting pipe 16 to the ultrasonic flow meter 1, thereby cleaning the ultrasonic flow meter 1 and facilitating subsequent contact between the ultrasonic flow meter 1 and the water pipe for pressure and flow detection.

[0049] The storage frame 21 at the top of the ultrasonic flow meter 1 slides. The storage frame 21 slides through the slider 32 in the slide groove 31, and the pads 33 on both sides of the slider 32 increase friction, allowing the storage frame 21 to stop at any position. When the storage frame 21 slides to a suitable position and stops, the first multi-stage telescopic tube 25 is pulled, causing the first multi-stage telescopic tube 25, along with the second magnetic block 273, hollow frame 281, brush plate 26, and outlet pipe 24, to move downwards (at this time, the area directly below the first multi-stage telescopic tube 25 is no longer the ultrasonic flow meter 1, but empty, so the first multi-stage telescopic tube 25 can be pulled down). As the second magnetic block 273 moves along with the first multi-stage telescopic tube 25, the first magnetic block 272 separates from the second magnetic block 273. Under the action of the elastic rope, the first magnetic block 272 slides back into the support plate 22 via the slide rod 271. At this time, the first magnetic block 272 and the second magnetic block 273 no longer clamp the closed outlet tube 24, allowing the coupling agent in the storage box 23 to enter the hollow frame 281 through the outlet tube 24, and then flow through several outlet holes 282 of the hollow frame 281 to the back of the ultrasonic flow meter 1 (i.e., the surface in contact with the tap water pipe). The hollow frame 281 moves along with the brush plate 26, which evenly brushes the outflowing coupling agent.

[0050] After the first multi-stage telescopic tube 25 is used, it will reset along with components such as the hollow frame 281. During reset, the coupling agent can still be applied again using the brush plate 26 to maximize the application of coupling agent to the ultrasonic flow meter 1. Furthermore, after reset, the first multi-stage telescopic tube 25 will use the second magnetic block 273 to attract the first magnetic block 272 again. The first magnetic block 272 and the second magnetic block 273 work together to clamp and close the outlet tube 24, effectively preventing the coupling agent from flowing out.

[0051] After completing the above operations, ensure that the two movable clamps 13 are fully aligned with the water pipe, and tighten the bolts 14 into the threaded holes 15 for fixation, thus securing the ultrasonic flow meter 1 to the water pipe via the two movable clamps 13. It should be noted that a buffer pad can be installed on the contact surface between the movable clamps 13 and the water pipe to protect the water pipe.

[0052] The aforementioned design enables rapid cleaning of the water pipe's inspection point. The cleaning and clamping structures are integrated into one unit, offering convenience and eliminating the need for workers to carry additional cleaning tools. Pre-cleaning also improves the detection accuracy of the ultrasonic flow meter 1. Furthermore, the coupling agent is integrated into the storage frame 21 of the ultrasonic flow meter 1, allowing for easy and even application of the agent through simple up-and-down movement. This eliminates the need for extensive experience-based application. Finally, the outlet pipe 24 can be automatically closed when the coupling agent is not in use. This integrated design eliminates the need for additional tools and parts such as coupling agents.

[0053] The storage frame 21 is equipped with a compression mechanism 40. The compression mechanism 40 includes a fixed frame 41 fixedly installed in the storage frame 21. The inside of the fixed frame 41 is a compression block 42 that is sealed and slidably connected. Several round tubes in the first multi-stage telescopic tube 25 are sealed and slidably connected, and the several round tubes are connected to each other through several through holes. The fixed frame 41 and the first multi-stage telescopic tube 25 are connected through an air guide tube 43.

[0054] Specifically, two symmetrically arranged and arc-shaped auxiliary plates 44 are fixedly installed at the bottom of the extrusion block 42, and a rolling column 45 is rotatably connected to one side of the auxiliary plate 44.

[0055] During operation, when the first multi-stage telescopic tube 25 is pulled down, it draws gas out of the fixed frame 41 through the air guide tube 43. The gas then enters the first multi-stage telescopic tube 25 through the air guide tube 43 and passes through several through holes in the first multi-stage telescopic tube 25 into several circular tubes. At this time, the extrusion block 42, along with the auxiliary plate 44 and the rolling column 45 (both made of lightweight materials), moves towards the deformable liquid storage box 23. The extrusion block 42 and other components assist in extruding the liquid storage box 23, thereby accelerating the flow of the coupling agent and preventing the ultrasonic flow meter 1 from being unable to be fully coated with the required coupling agent due to a slow flow rate. When the first multi-stage telescopic tube 25 resets, it guides the gas back into the fixed frame 41 through the air guide tube 43, thereby resetting the extrusion block 42 and other components and no longer applying pressure to the liquid storage box 23, thus reducing the outflow of coupling agent.

[0056] A scraping mechanism 50 is provided inside the connecting frame 11. The scraping mechanism 50 includes several second elastic balls 51 that are fixedly installed inside the connecting frame 11 and fixedly connected to the movable clamping plate 13. A second multi-stage telescopic tube 52 is fixedly installed on one side of the movable clamping plate 13. The second multi-stage telescopic tube 52 is composed of several hollow round tubes that are sealed and slidably connected. The several round tubes are connected to each other through several through holes. The second multi-stage telescopic tube 52 and the several second elastic balls 51 are connected to each other through a connecting pipe 53. A rotating rod 54 is rotatably connected to the bottom of the second multi-stage telescopic tube 52. A scraper 55 is fixedly installed at one end of the rotating rod 54. A cleaning plate 57 with a cleaning cloth is fixedly installed on the scraper 55 through several support rods 56.

[0057] Specifically, a spraying mechanism 60 is provided at the bottom of the second multi-stage telescopic tube 52. The spraying mechanism 60 includes a cavity 61 opened in the second multi-stage telescopic tube 52. A rubber box 63 is fixedly installed inside the cavity 61. A pipe with a one-way valve is fixedly installed on one side of the rubber box 63. A guide pipe with a one-way valve is fixedly installed on one side of the rubber box 63 and communicates with the inside. A fixing plate 62 is fixedly installed on the surface of the rotating rod 54.

[0058] During operation, when the movable clamp 13 slides within the connecting frame 11 (meaning when the movable clamp 13 slides and expands with the first elastic ball 12), the movable clamp 13 will squeeze the gas inside the second elastic ball 51 (initially filled with gas). This gas will then enter the second multi-stage telescopic tube 52 through the connecting pipe 53, and completely enter the hollow circular tubes within the second multi-stage telescopic tube 52 through several through holes. This causes the second multi-stage telescopic tube 52 to move downwards via the rotating rod 54, carrying the scraper 55 (which can be made of rubber, or a suitable material can be selected according to the actual situation, as long as it does not damage the ultrasonic flow meter 1) and the cleaning plate 57 (with a cleaning cloth facing the ultrasonic flow meter 1). This assists in cleaning the ultrasonic flow meter 1, facilitating the subsequent application of coupling agent to the ultrasonic flow meter 1. When the movable clamp 13 resets (meaning it is not squeezing the second elastic ball 51), the gas inside the second multi-stage telescopic tube 52 resets back into the second elastic ball 51 through the connecting pipe 53. At this time, the scraper 55 and the cleaning plate 57 will also reset accordingly. After completing the above operations, the scraper 55 and cleaning cloth are rotated away from the ultrasonic flow meter 1 by rotating the rod 54, thereby ensuring that the scraper 55 and other components do not affect the subsequent coating work.

[0059] After the ultrasonic flow meter 1 completes its testing task, the coupling agent on the ultrasonic flow meter 1 needs to be cleaned promptly. At this time, rotate the rotating rod 54, along with the fixing plate 62, away from the ultrasonic flow meter 1. The fixing plate 62 will squeeze the liquid (which can be water or other liquids depending on the actual situation) in the rubber box 63 and spray it onto the ultrasonic flow meter 1 (the side with the coupling agent) through the guide pipe 64. After completing the above operation, reset the scraper 55 (i.e., one side of the scraper 55 is in contact with one side of the ultrasonic flow meter 1). Then, in conjunction with the sliding clamp 13, the second elastic ball 51 will be disassembled by sliding and pressing the second elastic ball. After being compressed, the second multi-stage telescopic tube 52, scraper 55, and cleaning plate 57 will move again, thereby scraping away and cleaning the residual coupling agent on the ultrasonic flow meter 1.

[0060] The structure designed above allows for sliding clamping using the movable clamping plate 13, first completing auxiliary cleaning of the water pipe to facilitate subsequent testing of the water pipe by the ultrasonic flow meter 1. Simultaneously, during disassembly, the sliding of the movable clamping plate 13 again cleans the coupling agent used on the ultrasonic flow meter 1, eliminating the need for separate cleaning of the coupling agent and preventing the mixing of residual coupling agent from affecting testing accuracy.

[0061] The ultrasonic flow meter 1 has a storage mechanism 70 at its bottom. The storage mechanism 70 includes a storage box 72 located at the bottom of the ultrasonic flow meter 1. The storage box 72 is connected to the storage frame 21 by a fixing rod 71. An arc-shaped flow guide block 73 is fixedly installed inside the storage box 72. Several protrusions 74 are fixedly installed inside the slide groove 31.

[0062] During operation, a collection box 72 is installed at the bottom of the ultrasonic flow meter 1, and the collection box 72 and the collection frame 21 move synchronously via a fixing rod 71. When the coupling agent is sprayed, excess coupling agent will fall off, which is then collected and stored in the collection box 72. When the rubber box 63 is used to remove the coupling agent with the liquid-assisted scraper 55, the collection box 72 also serves to collect and store the coupling agent, thus reducing the need for cleaning up after it falls to the ground. The arc-shaped guide block 73 is designed to guide the collected coupling agent and other substances deep into the collection box 72, preventing them from accumulating in one place and overflowing. When the collection frame 21 slides back to its original position via the slider 32, it contacts the protrusion 74 and vibrates, causing the coupling agent inside the collection box 72 to vibrate, thereby accelerating the flow of the coupling agent and ensuring it is evenly stored in the collection box 72, improving the utilization rate of the collection box 72. Meanwhile, after the storage box 72 is reset along with the storage frame 21, the bottom of the ultrasonic flow meter 1 seals the top of the storage box 72 to prevent the coupling agent inside the storage box 72 from flowing out when it is being carried.

[0063] Working Principle: When using the ultrasonic flow meter 1 to detect the pressure and flow rate of a tap water pipe, first bring the ultrasonic flow meter 1 close to the tap water pipe. Slide the movable clamps 13 inside the two connecting frames 11, allowing the two movable clamps 13 to slide away from each other. When the movable clamps 13 slide, they cause the first elastic balls 12 to expand, thereby drawing external gas into the first elastic balls 12 through the connecting pipe 16. This operation increases the gap between the two movable clamps 13, making it easier to place the tap water pipe between them. After completing the above operation, release the two movable clamps 13, allowing several first elastic balls 12 to return to their original position along with the movable clamps 13, thus allowing the two movable clamps 13 to clamp the tap water pipe. It should be noted that at this time, the two movable clamps 13 do not completely clamp and fix the tap water pipe, and when the several first elastic balls 12 return to their original position, they will blow the internal gas through the connecting pipe 16 towards the ultrasonic flow meter 1, cleaning the ultrasonic flow meter 1 and facilitating subsequent contact between the ultrasonic flow meter 1 and the tap water pipe for pressure and flow rate detection.

[0064] The storage frame 21 at the top of the ultrasonic flow meter 1 slides via a slider 32 within a groove 31. The pads 33 on both sides of the slider 32 increase friction, allowing the storage frame 21 to stop at any position. When the storage frame 21 stops at the desired position, the first multi-stage telescopic tube 25 is pulled, causing it to move downwards along with the second magnet 273, the hollow frame 281, the brush plate 26, and the outlet pipe 24. As the second magnetic block 273 moves along with the first multi-stage telescopic tube 25, the first magnetic block 272 separates from the second magnetic block 273. Under the action of the elastic rope, the first magnetic block 272 slides back into the support plate 22 via the slide rod 271. At this time, the first magnetic block 272 and the second magnetic block 273 no longer clamp the closed outlet tube 24, allowing the coupling agent in the storage box 23 to enter the hollow frame 281 through the outlet tube 24, and then flow to the back of the ultrasonic flow meter 1 through several outlet holes 282 of the hollow frame 281. The hollow frame 281 moves along with the brush plate 26, which evenly brushes the outflowing coupling agent. After the first multi-stage telescopic tube 25 is used, it resets along with the hollow frame 281 and other components. During the reset, the brush plate 26 can still be used to brush the coupling agent again, thereby maximizing the application of coupling agent to the ultrasonic flow meter 1. Furthermore, after resetting, the first multi-stage telescopic tube 25 will use the second magnet 273 to attract the first magnet 272 again. The first magnet 272 and the second magnet 273 work together to clamp the closed outlet tube 24, effectively preventing the coupling agent from flowing out. After completing the above operations, ensure that the two movable clamps 13 are fully attached to the water pipe, and tighten the bolts 14 into the threaded holes 15 for fixation, so that the two movable clamps 13, along with the ultrasonic flow meter 1, are fixed to the water pipe. It should be noted that a buffer pad can be installed on the contact surface between the movable clamps 13 and the water pipe to protect the water pipe.

[0065] When the first multi-stage telescopic tube 25 is pulled down, it draws the gas out of the fixed frame 41 through the air guide tube 43. The gas then enters the first multi-stage telescopic tube 25 through the air guide tube 43 and passes through several through holes in the first multi-stage telescopic tube 25 into several circular tubes. At this time, the extrusion block 42, along with the auxiliary plate 44 and the rolling column 45, moves towards the deformable liquid storage box 23. The extrusion block 42 and other components assist in extruding the liquid storage box 23, thereby accelerating the flow of the coupling agent and preventing the ultrasonic flow meter 1 from being unable to be fully coated with the required coupling agent due to a slow flow rate. When the first multi-stage telescopic tube 25 resets, it guides the gas back into the fixed frame 41 through the air guide tube 43, thereby resetting the extrusion block 42 and other components and no longer applying pressure to the liquid storage box 23, thus reducing the outflow of coupling agent.

[0066] When the movable clamp 13 slides within the connecting frame 11, it compresses the gas inside the second elastic ball 51, allowing the gas to enter the second multi-stage telescopic tube 52 through the connecting pipe 53. The gas then passes through several through holes and completely enters the hollow circular tubes within the second multi-stage telescopic tube 52. This causes the second multi-stage telescopic tube 52 to move downwards via the rotating rod 54, carrying the scraper 55 and cleaning plate 57, thus assisting in cleaning the ultrasonic flow meter 1 and facilitating the subsequent application of coupling agent to the ultrasonic flow meter 1. When the movable clamp 13 resets, the gas inside the second multi-stage telescopic tube 52 returns to the second elastic ball 51 through the connecting pipe 53, and the scraper 55 and cleaning plate 57 also reset accordingly. After completing the above operations, the rotating rod 54 rotates the scraper 55 and cleaning cloth away from the ultrasonic flow meter 1, ensuring that the scraper 55 and other components do not interfere with the subsequent coupling application process. After the ultrasonic flow meter 1 completes its testing task, the coupling agent on the ultrasonic flow meter 1 needs to be cleaned promptly. At this time, rotate the rotating rod 54, along with the fixed plate 62, away from the ultrasonic flow meter 1. The fixed plate 62 will squeeze the liquid in the rubber box 63 and spray it onto the ultrasonic flow meter 1 through the guide pipe 64. After completing the above operation, reset the scraper 55. Then, in conjunction with the subsequent sliding clamp 13, the second elastic ball 51 will be disassembled by sliding and squeezing the second elastic ball 51. After being squeezed, the second multi-stage telescopic tube 52, scraper 55, and cleaning plate 57 will move again, thereby scraping away and cleaning the coupling agent remaining on the ultrasonic flow meter 1.

[0067] By installing a collection box 72 at the bottom of the ultrasonic flow meter 1 and using a fixing rod 71 to move the collection box 72 and the collection frame 21 synchronously, excess coupling agent will fall when it is sprayed out. The collection box 72 is used to collect and store this excess agent. When the rubber box 63 uses the liquid-assisted scraper 55 to remove the coupling agent, the collection box 72 also serves to collect and store it, reducing the need for cleaning up spilled materials. The arc-shaped guide block 73 is designed to guide the collected coupling agent and other substances deep into the collection box 72, preventing them from accumulating in one place and overflowing. When the collection frame 21 slides back to its original position via the slider 32, it contacts the protrusion 74 and vibrates, causing the coupling agent inside the collection box 72 to vibrate, thus accelerating the flow of the coupling agent and ensuring it is evenly stored within the collection box 72, improving its utilization rate. Meanwhile, after the storage box 72 is reset along with the storage frame 21, the bottom of the ultrasonic flow meter 1 seals the top of the storage box 72 to prevent the coupling agent inside the storage box 72 from flowing out when it is being carried.
