Description

Technical Field

[0001] This utility model belongs to the field of installation technology of external clamp ultrasonic flow meters, and particularly relates to an external clamp ultrasonic sensor clamp. Background Technology

[0002] During the on-site installation and commissioning of clamp-on ultrasonic flow meters, matching clamps are required for their fixed installation. For pipes of different diameters, the clamps currently on the market are complex and bulky, have a large number of parts, and one set of clamps cannot adapt to different sizes, which affects the installation efficiency.

[0003] Chinese invention patent application number 202411412617.4 discloses an auxiliary device for ultrasonic flow measurement in small-diameter pipes, including a transducer clamp, a semi-circular tube, a hinge mechanism, a connecting buckle, a restraining cable, a torque controller, and a connecting hook. The semi-circular tube can be easily opened or closed for quick installation or removal of the test pipe. The restraining cable ensures a tight fit between the test pipe and the measurement auxiliary device, and for flexible pipes, it can effectively constrain the pipe shape to keep its diameter constant, thereby improving the accuracy of the test. This measurement auxiliary device can effectively solve the problem of measurement failure due to the small difference in the diameter of the test pipe causing the pipe and clamp to not fit tightly. However, this structure is only applicable to the transducer and not to the installation and debugging of the ultrasonic sensor in this application. Utility Model Content

It has a simple structure, is easy to install and debug, can adapt to different pipe diameters, and can firmly fix the ultrasonic sensor on the pipe, thereby improving the alignment accuracy between the ultrasonic sensor and the pipe.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] An external clamping ultrasonic sensor fixture includes a sensor fixing component, a fixture body, guide rods, and a retaining ring. The fixture body is a C-shaped frame. The sensor fixing component is located inside the fixture body. The upper edge of the fixture body is connected to the top of the sensor fixing component by screws. The upper edge of the fixture body is provided with a V-shaped positioning groove, and the side edge of the fixture body is provided with a longitudinal groove. The side of the sensor fixing component is connected to two guide rods, one above the other. The ends of the guide rods protrude from the longitudinal grooves, and retaining rings that limit the movement are provided at the ends of the guide rods.

[0007] Furthermore, the sensor fixture is provided with a slot for accommodating the ultrasonic sensor, and the bottom of the slot is open.

[0008] Furthermore, the centerline of the groove corresponds vertically to the centerline of the V-shaped positioning groove.

[0009] Furthermore, the ultrasonic sensor is an external clamp-on ultrasonic sensor.

[0010] Furthermore, the V-shaped positioning groove is applicable to pipes with an outer diameter range of 5 to 200 mm.

[0011] Furthermore, the screw's lifting adjustment range is 5-15mm.

[0012] Furthermore, the end of the guide rod is provided with a limiting boss on the inner side corresponding to the longitudinal groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) The clamp has a simple structure, is easy to install and debug, and can adapt to different pipe diameters. The clamp can firmly fix the sensor to the pipe, and the alignment accuracy of the ultrasonic sensor and the pipe is significantly improved.

[0015] 2) The sensor mounting hardware facilitates the fixing of the ultrasonic sensor, enabling it to be directly aligned with the pipe and placed stably on the pipe.

[0016] 3) The clamp is equipped with a tightening bolt at the top, which cooperates with the lower end of the clamp to ensure that the pipe and the ultrasonic sensor fit tightly together. This structure has a wide range of applications and can be used for various external clamp ultrasonic sensors. Attached Figure Description
