Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, specifically a pipeline capacity measuring device. Background Technology

[0002] Pipe capacity measurement aims to determine the volume or flow rate of fluids, such as gases, liquids, or solid particles, that can be contained within a pipe. This is crucial for the design, optimization, monitoring, and maintenance of pipes and is of great significance in many fields, such as communications, municipal water supply, and industrial fluid transport.

[0003] Existing pipe capacity measuring devices, such as the Chinese utility model patent CN218724592U entitled "A Calibration and Verification Device for Pipe Capacity Measurement," include an upper frame and a lower frame. The lower frame is fixedly connected to the lower end of the upper frame by bolts. Fixing mechanisms are fixedly installed at the middle of the upper end face and near the middle of both side end faces of the upper frame. An ultrasonic detection mechanism, including an oil tank and a lead screw, is fixedly installed near the middle of the upper end face of the lower frame. While this patent solution can achieve ultrasonic capacity measurement, after installation and fixing, it can only measure very short pipe lengths, and cannot measure longer pipes and then take an average value. The measurement accuracy is not high, and the number of ultrasonic measuring mechanisms is fixed, making it difficult to easily adjust for pipes of different diameters, resulting in insufficient overall applicability. Therefore, a pipe capacity measuring device needs to be designed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe capacity measuring device to solve the problems mentioned in the background art, which are that the existing devices can only measure very short pipe lengths after installation and fixation, and cannot measure longer pipes and then take the average value, resulting in low measurement accuracy. In addition, the number of ultrasonic measuring mechanisms installed is fixed, and it is not convenient to adjust them according to pipes of different diameters, resulting in insufficient overall applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline capacity measuring device, comprising a mounting base plate, a track window opened on the horizontal portion of the mounting base plate, a bottom positioning bolt installed through the track window, a bottom positioning nut installed on the bottom positioning bolt, the top end of the bottom positioning bolt being connected and fixed to the bottom end of a movable plate, a stabilizing hole opened on the top of the movable plate, a central threaded rod installed through the stabilizing hole, a locking nut installed on the central threaded rod, the bottom of the central threaded rod passing through the track window, an ultrasonic detection mechanism installed at the bottom end of the central threaded rod, a side positioning bolt fixedly installed at the end of the mounting base plate, a side positioning nut installed on the side positioning bolt, the end of the side positioning bolt fitting against the inner wall of a limiting groove, the limiting groove being opened on one side of a clamp, an adjusting threaded rod installed on the other side of the outer wall of the clamp away from the limiting groove, and an anti-slip pad fixedly installed at the end of the adjusting threaded rod.

[0006] Preferably, the track windows are symmetrically distributed about the center of the mounting base plate, and the length of the track windows is greater than half the overall length of the mounting base plate.

[0007] Preferably, the center of the bottom positioning bolt and the center of the middle threaded rod are on the same vertical plane, and the bottom positioning bolt and the middle threaded rod have the same diameter.

[0008] Preferably, the bottom positioning bolts and the middle threaded rod are slidably connected to the track window. The bottom positioning bolts are symmetrically distributed about the center of the movable plate, and the middle threaded rod is symmetrically installed with locking nuts about the center of the stabilizing hole.

[0009] Preferably, the side positioning bolts are symmetrically distributed about the center of the mounting base plate, the side positioning bolts are slidably connected to the limiting groove, the bottom view of the limiting groove is "T" shaped, and the side view of the limiting groove is annular.

[0010] Preferably, the adjusting threaded rod and the clamp are threadedly connected, the adjusting threaded rod is distributed at equal angles about the center of the clamp, and the length of the adjusting threaded rod is greater than twice the thickness of the clamp.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the pipe capacity measuring device adopts a novel structural design, which not only allows for convenient adjustment of the number and installation position of the ultrasonic detection mechanism based on the pipe diameter, but also allows for a wide range of adjustment of the horizontal position after the ultrasonic detection mechanism is installed, enabling detection of pipes over long distances, and greatly improving the overall applicability and detection accuracy.

[0012] 1. The device can be stably installed by using a clamp and adjusting the threaded rod, which can accommodate pipes of different diameters. At the same time, the limiting groove on the side of the clamp allows the side positioning bolts to be easily installed, disassembled, and slidably adjusted to change the installation position, which facilitates the adjustment of the number and position of the ultrasonic detection mechanism.

[0013] 2. By sliding the movable plate with the bottom positioning bolt horizontally along the track window and cooperating with the threaded rod to slide vertically along the stabilizing hole, the horizontal working position and vertical height of the ultrasonic detection mechanism can be easily adjusted, ensuring that the ultrasonic detection mechanism can be stably attached to the pipeline, and at the same time, it can measure pipelines over long distances.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution: a pipeline capacity measuring device, including a mounting base plate 1, a track window 2, a bottom positioning bolt 3, a bottom positioning nut 4, a movable plate 5, a stabilizing hole 6, a central threaded rod 7, a locking nut 8, an ultrasonic detection mechanism 9, a side positioning bolt 10, a side positioning nut 11, a limiting groove 12, a clamp 13, an adjusting threaded rod 14, and an anti-slip pad 15. The mounting base plate 1 has a track window 2 on its horizontal portion. A bottom positioning bolt 3 is installed through the track window 2. A bottom positioning nut 4 is installed on the bottom positioning bolt 3. The top end of the bottom positioning bolt 3 is connected and fixed to the bottom end of the movable plate 5. A stabilizing hole 6 is provided at the top of the 5. A central threaded rod 7 is installed through the stabilizing hole 6. A locking nut 8 is installed on the central threaded rod 7. The bottom of the central threaded rod 7 passes through the track window 2. An ultrasonic detection mechanism 9 is installed at the bottom of the central threaded rod 7. A side positioning bolt 10 is fixedly installed at the end of the mounting base plate 1. A side positioning nut 11 is installed on the side positioning bolt 10. The end of the side positioning bolt 10 fits against the inner wall of the limiting groove 12. The limiting groove 12 is opened on one side of the clamp 13. An adjusting threaded rod 14 is installed on the other side of the outer wall of the clamp 13 away from the limiting groove 12. An anti-slip pad 15 is fixedly installed at the end of the adjusting threaded rod 14.

[0022] The track window 2 is symmetrically distributed about the center of the mounting base plate 1. The length of the track window 2 is greater than half the overall length of the mounting base plate 1. The above structural design ensures that the bottom positioning bolt 3 and the middle threaded rod 7 can move a sufficient distance along the track window 2.

[0023] The center of the bottom positioning bolt 3 and the center of the middle threaded rod 7 are on the same vertical plane. The bottom positioning bolt 3 and the middle threaded rod 7 have the same diameter. The above structural design ensures that the bottom positioning bolt 3 and the middle threaded rod 7 can stably fit with the track window 2, ensuring the stability of the device during installation and adjustment.

[0024] Both the bottom positioning bolt 3 and the middle threaded rod 7 are slidably connected to the track window 2. The bottom positioning bolt 3 is symmetrically distributed about the center of the movable plate 5. The middle threaded rod 7 is symmetrically installed with locking nuts 8 about the center of the stabilizing hole 6. The above structure allows the movable plate 5 to slide stably along the track window 2 with the bottom positioning bolt 3 and the middle threaded rod 7, and the relative position of the middle threaded rod 7 and the stabilizing hole 6 can be quickly fixed.

[0025] The side positioning bolts 10 are symmetrically distributed about the center of the mounting base plate 1. The side positioning bolts 10 are slidably connected to the limiting groove 12. The bottom view of the limiting groove 12 is T-shaped, and the side view of the limiting groove 12 is annular. The above structural design enables the side positioning bolts 10 to be stably connected to the clamp 13 through the limiting groove 12 without horizontal separation, and the installation position can be smoothly adjusted along the limiting groove 12.

[0026] The adjusting threaded rod 14 and the clamp 13 are connected by threads. The adjusting threaded rod 14 is distributed at equal angles with respect to the center of the clamp 13. The length of the adjusting threaded rod 14 is more than twice the thickness of the clamp 13. The above structural design allows the adjusting threaded rod 14 to be stably screwed into the clamp 13, and the clamp 13 is fixedly installed on pipes of different diameters.

[0027] Working principle: When using this device, first select an appropriate number of mounting base plates 1 according to the measurement requirements of the pipeline. Slide the side positioning bolts 10 at the end of the mounting base plate 1 into the opening of the limiting groove 12 at the end of the unclosed clamp 13. Install the clamps 13 on both ends of the mounting base plate 1. Then close the clamps 13 and install them on the outside of the pipeline to be tested. According to the pipeline diameter, rotate the adjusting threaded rod 14 in the direction of the pipeline until the adjusting threaded rod 14 squeezes the anti-slip pad 15 and stably fits against the outer wall of the pipeline, thus completing the overall installation of the device.

[0028] Subsequently, according to the testing requirements, the movable mounting base plate 1, along with the side positioning bolt 10, slides along the limiting groove 12 until the ultrasonic detection mechanism 9 on different mounting base plates 1 is in the appropriate position. The side positioning nut 11 is rotated to press the side wall of the clamp 13, fixing the position of the mounting base plate 1. Then, the symmetrically distributed locking nuts 8 are rotated away from the movable plate 5, pushing the central threaded rod 7 to slide vertically along the stabilizing hole 6 and the track window 2 until the ultrasonic detection mechanism 9 is in contact with the outer wall of the pipe. The symmetrically distributed locking nuts 8 are rotated to press the two sides of the movable plate 5, fixing the positions of the central threaded rod 7 and the ultrasonic detection mechanism 9. The ultrasonic detection mechanism 9 can then be started for testing.

[0029] After a single test, the bottom positioning nut 4 can be rotated away from the mounting base plate 1, pushing the movable plate 5 to slide linearly along the track window 2 with the bottom positioning bolt 3, changing the working position of the movable plate 5 and the ultrasonic detection mechanism 9, and performing multiple tests on different parts of the pipeline to improve the accuracy of the test. This is the working principle of the pipeline capacity measuring device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
