Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flow measurement technology, and in particular to the sensor distribution structure of a gas ultrasonic flow meter. Background Technology

[0002] Ultrasonic gas flow meters are instruments that measure gas flow rate by utilizing the time difference of ultrasonic wave propagation. Due to their advantages such as wide rangeability, high accuracy, and no pressure loss, they are increasingly used in gas metering and pipeline monitoring. Existing clamp-on ultrasonic gas flow meters typically mount the sensor on the outer wall of the pipe to avoid drilling or welding into the pipe.

[0003] However, in practical applications, external clamp sensors are mostly installed by threading, binding, or bracket fixing, which not only requires a variety of tools and many operation steps, but also takes a long time to install, affecting installation efficiency and maintenance convenience. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sensor distribution structure for a gas ultrasonic flow meter, aiming to improve the problem of numerous installation steps for external clamp-on sensors, which affects installation efficiency and maintenance convenience.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A gas ultrasonic flow meter sensor distribution structure includes a frame, a sliding frame on the inner wall of the frame, a push plate slidably connected to the inner wall of the sliding frame, a U-shaped block fixedly connected to the outer wall of the push plate, a locking block fixedly connected to the outer wall of the U-shaped block, a sensor body on the outer wall of the locking block, a locking groove inside the sensor body, the outer wall of the locking block being disposed on the inner wall of the locking groove, a spring fixedly connected to the inner wall of the U-shaped block, the outer wall of the spring fixedly connected to the inner wall of the sliding frame, and a fixing component on the inner wall of the frame.

[0006] The above technical solution works as follows: First, push the push plates on both sides to move the U-shaped block. The movement of the U-shaped block will also move the locking block. When the locking block slides out of the inner wall of the slot, the limiting effect on the sensor body can be released, allowing the sensor body to be removed from the sliding frame. When installation is required, the sensor body is placed back into the sliding frame, and the spring force pushes the U-shaped block to slide, thereby moving the locking block into the inner wall of the slot, achieving a quick fixation effect. The quick installation and removal of the sensor body can significantly improve the installation efficiency and maintenance convenience of the sensor body.

[0007] Preferably, the fixing component includes a pipe, the outer wall of which is disposed on the inner wall of the frame, and the frame has mounting holes inside.

[0008] Preferably, the inner wall of the frame is slidably connected to a second push plate, and the outer wall of the second push plate is fixedly connected to a connecting column.

[0009] Preferably, a second locking block is fixedly connected to the outer wall of the connecting column, and the outer wall of the second locking block is disposed on the inner wall of the sliding frame.

[0010] Preferably, the sliding frame has a groove inside, and the outer wall of the second card block is disposed on the inner wall of the groove.

[0011] Preferably, the sliding frame has a sliding column slidably connected inside, and the outer wall of the sliding column is fixedly connected to the inner wall of the frame.

[0012] Preferably, the inner wall of the frame is fixedly connected to a second spring, and the outer wall of the second spring is fixedly connected to the outer wall of the second locking block.

[0013] Preferably, the inner wall of the frame is fixedly connected to a slide rail, and the outer wall of the slide rail is slidably connected to the inner wall of the sliding frame.

[0014] This utility model has the following beneficial effects: 1.

[0015] 2.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figure 1 and Figure 2 An embodiment of this utility model provides a gas ultrasonic flow meter sensor distribution structure, including a frame 1, a sliding frame 2 provided on the inner wall of the frame 1, a push plate 3 slidably connected to the inner wall of the sliding frame 2, a U-shaped block 4 fixedly connected to the outer wall of the push plate 3, a locking block 5 fixedly connected to the outer wall of the U-shaped block 4, a sensor body 6 provided on the outer wall of the locking block 5, a locking groove 7 opened inside the sensor body 6, the outer wall of the locking block 5 being provided on the inner wall of the locking groove 7, a spring 8 fixedly connected to the inner wall of the U-shaped block 4, the outer wall of the spring 8 fixedly connected to the inner wall of the sliding frame 2, and a fixing component provided on the inner wall of the frame 1. Specifically, the sliding frame 2 provides sliding support for the push plate 3. When the push plate 3 is pushed, it causes the U-shaped block 4 to slide, which in turn causes the locking block 5 to slide. When the locking block 5 slides out of the inner wall of the slot 7, the limiting fixation of the sensor body 6 is released, allowing the sensor body 6 to be removed from the inner wall of the sliding frame 2, achieving a quick disassembly effect. When it is necessary to re-fix the sensor body 6, first place the sensor body 6 into the inner wall of the sliding frame 2. The sliding frame 2 provides elastic support for the spring 8. The spring force of the spring 8 pushes the U-shaped block 4 to slide, which in turn causes the locking block 5 to slide. When the locking block 5 slides into the inner wall of the slot 7, it quickly limits and fixes the sensor body 6. Through the quick disassembly and assembly of the sensor body 6, workers can quickly replace and install the sensor body 6 without using tools, significantly improving the installation efficiency and maintenance convenience of the sensor body 6.

[0020] Reference Figure 1 The fixing component includes a pipe 10, the outer wall of the pipe 10 is disposed on the inner wall of the frame 1, and the frame 1 has an installation hole 9 inside; Specifically, frame 1 can be divided into an upper frame and a lower frame. The upper frame and the lower frame can rotate to open frame 1. By opening frame 1, it can be fitted onto the outer wall of pipe 10. Then, by rotating, the upper and lower frames can be closed. Finally, the upper and lower frames are fixed together at the mounting hole 9 by bolts or other means, thereby achieving the effect of fixing frame 1 to the outer wall of pipe 10.

[0021] Reference Figure 3 The inner wall of frame 1 is slidably connected to a push plate 11, and the outer wall of push plate 11 is fixedly connected to a connecting column 12; the outer wall of connecting column 12 is fixedly connected to a locking block 13, and the outer wall of locking block 13 is set on the inner wall of sliding frame 2; a groove 14 is opened inside sliding frame 2, and the outer wall of locking block 13 is set on the inner wall of groove 14; a sliding column 15 is slidably connected inside sliding frame 2, and the outer wall of sliding column 15 is fixedly connected to the inner wall of frame 1; a spring 16 is fixedly connected to the inner wall of frame 1, and the outer wall of spring 16 is fixedly connected to the outer wall of locking block 13. Specifically, frame 1 provides sliding support for the upper and lower push plates 11. When push plates 11 are pushed, they cause the connecting post 12 to slide. The sliding of the connecting post 12 also causes the locking block 13 to slide. When the locking block 13 slides out of the inner wall of the groove 14, the limiting and fixing of the sliding frame 2 is released, allowing the sliding frame 2 to slide on the outer wall of the sliding post 15 to adjust the position of the sensor body 6. Frame 1 provides fixed support for the sliding post 15, while the sliding post 15 provides sliding support for the sliding frame 2. When the sensor body 6 is adjusted... When the frame reaches the appropriate preset position, the frame 1 can provide a limiting support for the spring 16. The elastic force of the spring 16 can push the locking block 13 into the inner wall of the groove 14, thus achieving the effect of limiting and fixing. By sliding the sliding frame 2, the position and spacing of the upper and lower sensor bodies 6 can be adjusted. A small spacing results in a short sound path, low ultrasonic attenuation, and high signal strength, while a large spacing results in a long sound path, a more obvious time difference between upstream and downstream propagation, and improved measurement resolution. By adjusting the spacing, users can flexibly adjust between signal strength and measurement accuracy according to actual conditions to adapt to different measurement needs.

[0022] Example 2: Reference Figure 4 The inner wall of frame 1 is fixedly connected to slide rail 17, and the outer wall of slide rail 17 is slidably connected to the inner wall of sliding frame 2. Specifically, frame 1 can provide fixed support for slide rail 17, while slide rail 17 can also replace sliding column 15 to provide sliding support for sliding frame 2.

[0023] Working principle: When the device is needed, push the push plate 3 first. The push plate 3 drives the U-shaped block 4 to slide. The sliding of the U-shaped block 4 will also drive the locking block 5 to slide out of the inner wall of the slot 7, releasing the limiting fixation of the sensor body 6. When it is necessary to fix it again, the elastic force of the spring 8 pushes the U-shaped block 4 to drive the locking block 5 to slide into the inner wall of the slot 7, which can achieve quick fixation. Through the quick disassembly and assembly of the sensor body 6, the staff can quickly replace and install the sensor body 6 without using tools, which significantly improves the installation efficiency and maintenance convenience of the sensor body 6. Then push the push plate 11, which drives the connecting column 12 to slide. The sliding of the connecting column 12 will also cause the locking block 13 to slide out of the inner wall of the groove 14, thereby releasing the limiting fixation of the sliding frame 2. This allows the sliding frame 2 to slide on the outer wall of the sliding column 15 to adjust its position. The sliding column 15 can provide sliding support for the sliding frame 2. Similarly, the slide rail 17 can also replace the sliding column 15 to provide sliding support for the sliding frame 2. After the sliding frame 2 has been adjusted, the elastic force of the spring 16 pushes the locking block 13 into the inner wall of the groove 14 to achieve the limiting fixation effect. By adjusting the position of the upper and lower sliding frames 2, users can flexibly adjust between signal strength and measurement accuracy according to the actual situation to adapt to different measurement needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
