Description

Technical Field

[0001] The utility model relates to an external clamping type sensor installation and testing mechanism. Background Art

[0002] Ultrasonic flow meters are generally used in the fields of petroleum, chemical industry, electric power, etc. The use of ultrasonic flow meters makes the metering process more convenient and faster, and the measurement more accurate. General ultrasonic flow meters are divided into pipeline type, clamp-on type, and insertion type. The clamp-on flow meter is generally installed on the outer wall of the pipeline for measurement.

[0003] When installing the existing clamp-on sensor of the ultrasonic flow meter, adhesive is often applied to the outer wall of the clamp-on sensor so that the sensor is bonded to the outer wall of the pipe. However, this fixing method can easily affect the installation efficiency and the flow rate test can be affected by many factors. Utility Model Content

This installation and fixing method is simpler and convenient for flow testing.

[0006] A tooling assembly, wherein the middle clamp holds the water pipe;

[0007] an adapter assembly mounted on the tooling assembly;

[0008] The adapter assembly is mounted on the tooling assembly by means of bolts, and the sensor body is mounted on the adapter assembly.

[0009] Furthermore, the tooling assembly includes symmetrically arranged frame-shaped bases, a clearance channel for clamping the water pipe is provided between the two bases, the two bases are fixed by bolts, and two long strip-shaped connecting grooves are opened on the bases.

[0010] Furthermore, the adapter assembly includes two adapter bodies, the adapter body is concave and has a flange, a waist-shaped hole is provided on the flange, a slope block is provided in the middle of the adapter body, and an installation hole is provided on the slope block for installing the sensor body, and the sensor body is connected to the water pipe through the installation hole.

[0011] Furthermore, the two adapter bodies are symmetrically arranged along the vertical line A in the middle of the same base.

[0012] Furthermore, the two adapter bodies are completely overlapped after being rotated 180° along the symmetrical center point C, and are arranged in the middle of the two installed bases.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0022] Embodiment 1

[0023] like Figure 1 , 2 As shown in , 5, an external clamping sensor installation and testing mechanism, characterized in that it includes:

[0024] A tooling assembly, wherein the middle clamp holds a water pipe 2;

[0025] an adapter assembly mounted on the tooling assembly;

[0026] The adapter assembly is mounted on the tooling assembly by means of bolts, and the sensor body 33 is mounted on the adapter assembly.

[0027] Furthermore, the tooling assembly includes a frame-shaped base 1 that is symmetrically arranged, a clearance channel 11 for clamping the water pipe 2 is provided between the two bases 1, the two bases 1 are fixed by bolts, and two long strip-shaped connecting grooves 12 are provided on the base 1. The distance between the two sensor bodies 33 can be adjusted through the connecting grooves 12 to obtain the optimal installation distance for transmitting and receiving, so that the test results are accurate.

[0028] Further, the adapter assembly includes two adapter bodies 3, the adapter bodies 3 are concave and have flanges 31, the flanges 31 are provided with waist-shaped holes 34, the adapter bodies 3 can move horizontally in the waist-shaped holes 34, and are fixed by bolts after the adapter bodies 3 are moved to a suitable position, and the middle of the adapter bodies 3 has a ramp block 32, the ramp block 32 is provided with a mounting hole for the installation of the sensor body 33, and the sensor body 33 is connected to the water pipe 2 through the mounting hole. The adapter body 3 and the base 1 can ensure that the two sensor bodies 33 are correctly installed without deviation and without affecting the test flow.

[0029] Furthermore, the two adapter bodies 3 are symmetrically arranged along the vertical line A in the middle of the same base 1.

[0030] The test mechanism can adapt to pipe diameters and lengths within a certain range of sizes. By changing the clamping position and tooling length, it can adapt to pipe diameters of different sizes to achieve the test purpose. At the same time, the adapter body 3 can be designed separately according to the sensor body 33.

[0031] Embodiment 2

[0032] like Figure 2 , 3 , 4, 6 Further, the two adapter bodies 3 are completely overlapped after being rotated 180° along the symmetrical center point C on the center line B of the water pipe 2, and are arranged in the middle of the two installed bases 1.

[0033] This flow sensor is clamped on the outer wall of the pipe section without destroying the existing pipe section. When a pair of sensor bodies 33 are installed, they are coated with coupling glue and contact the outer wall of the pipe. Ultrasonic waves penetrate the pipe wall and pass through the liquid to be measured. The flow is detected in two ways: the reflective installation of embodiment 1 and the opposite-radiation installation of embodiment 2.

[0034] When the sensor body 33 is installed in an external clamp-on shooting and reflection mode, the emission and reception of the sensor body 33 need to be on the same path, and on the same plane in the longitudinal section. The two sensor bodies 33 in the sliding base 1 are adjusted to obtain the best emission and reception path, thereby obtaining the best installation position. The present application can adapt to water pipes 2 of different diameters with the help of the base 1 and the adapter body 3, and can also achieve the testing purpose.

[0035] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0036] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
