Description

Technical Field

[0001] This invention relates to the field of ultrasonic water meter technology, specifically to a high-range multi-channel ultrasonic water meter. Background Technology

[0002] Multi-channel ultrasonic water meters calculate flow rate by measuring the time difference between the forward and reverse flow of ultrasonic waves in a fluid. Their multi-channel design comprehensively captures water flow information, and non-contact measurement avoids mechanical wear, ensuring long-term stable operation. Advanced ultrasonic time-difference technology and optimized signal processing algorithms improve measurement accuracy and stability. Furthermore, their wide range ratio allows them to flexibly handle different flow ranges, ensuring accurate and stable measurement of fluid flow under various conditions. However, existing ultrasonic water meters may experience inaccurate measurements after a period of use. This is often closely related to the lack of an effective self-checking mechanism. Without a self-checking function, the water meter cannot autonomously detect its internal state and performance, making it difficult to promptly identify and correct potential measurement errors. When the performance of sensors, circuits, or other components inside the water meter deteriorates due to aging, wear, or environmental factors, these problems may persist and gradually accumulate, leading to deviations in measurement results if a self-checking mechanism is lacking. Therefore, we propose a high-range multi-channel ultrasonic water meter. Summary of the Invention

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-7 The present invention provides a technical solution: a high-range multi-channel ultrasonic water meter, comprising a water meter body 1 and a connecting pipe 11 disposed on the water meter body 1, wherein two sets of transducers 12 are disposed on the connecting pipe 11, and further comprising:

[0037] U-shaped tube 2 is connected to connecting tube 11, and two sets of transducers 12 are located between the openings of U-shaped tube 2;

[0038] Piston column 3 is slidably disposed inside U-shaped tube 2;

[0039] The push component 4 is set on the U-shaped tube 2 and connected to the piston column 3, and is used to drive the piston column 3 to move at a constant speed, so as to drive the water flow in the connecting tube 11 to move at a constant speed.

[0040] The ultrasonic reflector 5 is slidably disposed inside the connecting tube 11, and the two sets of transducers 12 are designed in a cross pattern.

[0041] Linkage 6 is set on connecting pipe 11, and ultrasonic reflector 5 and transducer 12 are connected to push assembly 4 through linkage 6. It is used to drive ultrasonic reflector 5 to rise and reflect ultrasonic waves so that the two sets of transducers 12 can be exchanged and docked.

[0042] Specifically, the two sets of transducers 12 are two ultrasonic generators and two ultrasonic receivers. These four transducers 12 are installed in four inclined tubes 54 respectively and are designed to be opposite each other in pairs, with one ultrasonic transmitter aligned with one ultrasonic receiver, so as to test the water flow.

[0043] When it is necessary to perform a self-test on the main body of the device, close the water valve connected to the connecting pipe 11 to make the water in the connecting pipe 11 static. Then, start the servo push rod 41 to drive the piston column 3 to move at a constant speed, thereby driving the water in the connecting pipe 11 to flow at a certain speed to test the main body of the device. This is relatively simple and convenient.

[0044] Simultaneously, activating the servo push rod 41 can drive the ultrasonic reflector 5 to rise, thereby reflecting ultrasonic waves. This allows the two sets of transducers 12 to be swapped and connected for testing, increasing the diversity of testing and improving the testing effect.

[0045] At the same time, when the ultrasonic reflector 5 is moved down and retracted, it will rotate 90 degrees to reduce its water-facing surface and avoid affecting the water flow velocity too much.

[0046] The pushing component 4 includes a servo push rod 41 fixedly connected to the U-shaped tube 2, and a sliding plate 42 slidably connected to the U-shaped tube 2. The sliding plate 42 is fixedly connected to the extended end of the servo push rod 41.

[0047] Furthermore, a sliding rod 43 is fixedly connected to the piston rod 3, and a sliding groove 44 is provided on the U-shaped tube 2. One end of the sliding rod 43 slides through the sliding groove 44, and the sliding plate 42 is connected to the sliding rod 43 to drive the piston rod 3 to move when the sliding plate 42 is moved.

[0048] The linkage 6 includes a hollow tube 45 fixedly connected to the connecting tube 11, a guide rod 46 slidably connected inside the hollow tube 45, the guide rod 46 is located inside the connecting tube 11 and fixedly connected to a rectangular block 47, and two ultrasonic reflective sheets 5 are provided, the two ultrasonic reflective sheets 5 are respectively installed on both sides of the rectangular block 47.

[0049] Specifically, when the device is working normally, the ultrasonic travel line between the two sets of transducers 12 is X-shaped, while after the rectangular block 47 is raised, the ultrasonic travel line between the two sets of transducers 12 becomes two V-shaped.

[0050] Furthermore, a Y-shaped bracket 48 is connected to one end of the guide rod 46, and a shaft 49 is fixedly connected to the bottom end of the Y-shaped bracket 48. An inclined groove 51 is provided on the sliding plate 42, and the end of the shaft 49 is located in the inclined groove 51 and slidably connected to its inner wall. This is used to drive the guide rod 46 to move when the sliding plate 42 is moved. Specifically, when the sliding plate 42 is moved, the inclined groove 51 pushes the shaft 49 to move, thereby driving the Y-shaped bracket 48 and the guide rod 46 to slide.

[0051] A hollow cylinder 52 is conductively connected to the connecting pipe 11. A sliding column 53 is slidably connected inside the hollow cylinder 52. An inclined tube 54 is fixedly connected to the sliding column 53. The inclined tube 54 is conductive to the connecting pipe 11, and the transducer 12 is installed inside the inclined tube 54. The transducer 12 and the inclined tube 54 are detachably connected to facilitate the replacement of the transducer 12 in the future. A transmission component 69 is provided between the sliding column 53 and the Y-shaped bracket 48 to drive the sliding column 53 to move when the Y-shaped bracket 48 is moved.

[0052] Specifically, when the ultrasonic reflector 5 is raised, since it is mounted on the rectangular block 47 and the rectangular block 47 and the ultrasonic reflector 5 itself have a certain thickness, the transducer 12 needs to be moved a certain distance into the connecting pipe 11 in a direction perpendicular to the connecting pipe 11 so that the ultrasonic reflector 5 can reflect the ultrasonic waves to the transducer 12 that receives the ultrasonic waves.

[0053] The transmission component 69 includes a round rod 55 fixedly connected to the sliding column 53, a U-shaped plate 56 fixedly connected to the Y-shaped bracket 48, a second inclined sliding groove 57 opened on the U-shaped bracket 56, the round rod 55 is located in the second inclined sliding groove 57 and is slidably connected to its inner wall, and is used to drive the sliding column 53 to move when the Y-shaped bracket 48 is moved.

[0054] The U-shaped plate 56 has a vertical sliding groove 58 that communicates with the inclined sliding groove 57. Specifically, when the U-shaped plate 56 is moved, the inclined sliding groove 57 pushes the round rod 55 to move, thereby driving the sliding column 53 to move. Then, the U-shaped plate 56 continues to move, driving the round rod 55 to embed into the vertical sliding groove 58, thereby locking the round rod 55 and improving the stability of the device.

[0055] Two rectangular protrusions 59 are symmetrically fixedly connected to one end of the sliding plate 42, and a transverse sliding groove 61 that communicates with the inclined sliding groove 51 is provided on the sliding plate 42.

[0056] Furthermore, a guide groove 62 is provided on the piston column 3, and an mounting plate 63 is fixedly connected inside the U-shaped tube 2. The mounting plate 63 slides through the guide groove 62, and springs 64 are fixedly connected to both sides of the mounting plate 63. One end of the spring 64 contacts and abuts against the inner wall of the piston column 3, which is used to provide self-recovering force when the piston column 3 is moved.

[0057] The sliding column 53 is located inside the connecting pipe 11 and has an arc-shaped design at one end to fit the inner wall of the connecting pipe 11.

[0058] The guide rod 46 is rotatably connected to the Y-shaped bracket 48. The guide rod 46 has a spiral groove 65, and a cylindrical protrusion 66 is fixedly connected inside the hollow tube 45. One end of the cylindrical protrusion 66 is located inside the spiral groove 65 and is slidably connected to its inner wall, which is used to drive the rectangular block 47 to rotate when the guide rod 46 is moved.

[0059] The guide rod 46 has a vertical sliding groove 67 that communicates with the spiral groove 65;

[0060] Specifically, the working process of this device is as follows: First, the water valve connected to the connecting pipe 11 is closed to make the water in the connecting pipe 11 static. Then, the servo push rod 41 is activated to retract a unit distance, pulling the sliding plate 42 to move. This, in turn, uses the rectangular protrusion 59 to push the sliding rod 43 to move, thereby driving the piston rod 3 to move. This causes the water in the connecting pipe 11 to flow at a certain speed, thus detecting the main body of the device. At the same time, the spring 64 is compressed to provide its self-recovery force, while the shaft 49 slides in the transverse sliding groove 68 without interference. Then, the servo push rod 41 is activated again. By pushing two unit distances, the inclined slide 51 pushes the shaft 49 to move, thereby driving the Y-shaped frame to move upward, which in turn drives the cylindrical protrusion 66 to slide in the spiral groove 65, so that the guide rod 46 and the rectangular block 47 rotate during the upward process. After that, the transducer 12 of the device works to perform self-test. At this time, due to the reflection of the ultrasonic reflector 5, the ultrasonic wave travels in a V-shape in the opposite direction of the water flow, thereby canceling the influence of the water flow velocity on the ultrasonic wave velocity. Therefore, no matter how large the water flow velocity is, the water flow velocity measured by the device should be close to zero, so as to improve the diversity of detection methods.

[0061] Example 2: Please refer to Figures 1-8 The present invention provides a technical solution: Embodiment 2 is an optimization based on Embodiment 1;

[0062] The sliding plate 42 has a transverse sliding groove 68 that is connected to the inclined sliding groove 51. After the ultrasonic reflector 5 is extended, the moving plate is pushed further, and the piston column 3 will drive the water flow to move, thereby inspecting the device and improving the diversity of detection methods.
