Description

Technical Field

[0001] The utility model relates to the field of ultrasonic flowmeters, and particularly to an innovative locking structure for ultrasonic flowmeters. Background Art

[0002] In currently commercially available ultrasonic flowmeters, since the installation of the probe is the key that affects the accuracy of the flowmeter, there are four common methods, namely Z, V, N, and W, mostly used in this field. The detailed settings will not be elaborated here. Among them, the V-type method can mostly be applied to the range of pipe diameters from 50 to 300 mm. Mainly, two probes are used on the same side of the pipe, and the ultrasonic wave is sent and received in a V-shaped path after bouncing once in the pipe. In this way, it is relatively easy to obtain the balance point of the signal strength, and thus more accurate data can be obtained.

[0003] For the aforementioned V-type method to make the signal bouncing path present a relatively stable V shape, the probe part must be accurately attached to the outer edge of the pipe, and the pipe also needs to be kept balanced. Therefore, when installing the ultrasonic flowmeter, it also needs to be installed smoothly. So, when performing the fixed installation and calibrating the stability, a lot of time is required for fine-tuning and calibration. Therefore, a structure that can reduce the cumbersome settings is needed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a snap-locking structure for an ultrasonic flowmeter, including: an ultrasonic flowmeter, a first bracket, and a second bracket. The first ultrasonic flowmeter has a control module for display and adjustment. A first space is provided inside the first bracket for connecting the ultrasonic flowmeter.

[0005] A snap-locking structure is arranged at the bottom of the ultrasonic flowmeter and inside the first space. By means of snap connection, the ultrasonic flowmeter can be fixedly connected to the first bracket, and the bottom of the first bracket is in a ∧ shape. A second space is formed in cooperation with a second bracket in a ∨ shape. After the second space clamps and restricts a fixed pipe, the first bracket and the second bracket are locked at an appropriate position of the fixed pipe with a plurality of screws, so that the ultrasonic flowmeter can easily measure the flow value in the fixed pipe.

[0006] Optionally, it further includes: a first lock hole is arranged on one side of the first bracket, and the first lock hole overlaps with a positioning lock hole on one side of the ultrasonic flowmeter to form a through state. The ultrasonic flowmeter is quickly locked to the first bracket with a quick screw.

[0007] Optionally, the first bracket is mainly clamped at an obtuse angle of 140 degrees, and the second bracket that cooperates with it is also at an obtuse angle of 140 degrees.

[0008] Optionally, the diameter of the fixed pipe can be replaced to be applicable to DN8 to DN65, but it must be adjusted according to the size of the second bracket.

[0009] The main advantages of the present utility model are that in addition to enabling the ultrasonic flowmeter to be installed quickly and operated simply, it can also be applicable to pipe diameters of different sizes, and has a multiple locking design to ensure the stable installation of the flowmeter, and is provided with a quick screw design for easy disassembly and assembly. The above features can effectively reduce the cumbersome steps of the existing structure and effectively achieve the purpose of convenient use.

[0010] The present utility model can quickly and stably configure ultrasonic flowmeters with different sizes of pipes to achieve compatibility, and can also perform accurate measurements. Description of the Drawings

[0032] Generally according to the present utility model, the best feasible embodiment, and in conjunction with the accompanying drawings Figures 1 to 6 After detailed description, the understanding of the present utility model is increased. The present utility model is a snap - lock structure of an ultrasonic flowmeter, including: an ultrasonic flowmeter 10, on the surface of which there is a control module 11 for displaying information and adjusting functions. This control module 11 can be designed as buttons or a touch panel, and the type of its use is not limited. And on the ultrasonic flowmeter 10, there is also a data connector, which can be used to connect to an external power supply and transmit data.

[0033] A first bracket 20, inside which there is a first space 21 for connecting the ultrasonic flowmeter 10. And on one side of the first bracket 20, there is also a first lock hole 22, and the first lock hole 22 overlaps and is in a through - state with a positioning lock hole 13 on one side of the ultrasonic flowmeter 10. The ultrasonic flowmeter 10 is quickly locked to the first bracket 20 through a quick - release screw 14, making its disassembly and assembly easier and simpler.

[0034] And a snap - lock structure 12 is arranged at the bottom of the ultrasonic flowmeter 10 and inside the first space 21. Through a buckling means, the ultrasonic flowmeter 10 can be fixedly connected to the first bracket 20, and the bottom of the first bracket 20 is in a ∧ - shape. Further, it cooperates with a second bracket 30 in a ∨ - shape to form a second space 31. After the second space 31 clamps and restricts a fixed pipe 40, then a plurality of screws 50 are used to lock the first bracket 20 and the second bracket 30 at an appropriate position of the fixed pipe 40, so that the ultrasonic flowmeter 10 can easily measure the flow value inside the fixed pipe 40.

[0035] The aforementioned second bracket 30 is mainly designed with an obtuse angle of 140 degrees, mainly used to cooperate with the first bracket 20 also designed with an obtuse angle of 140 degrees to clamp the fixed pipe 40. The diameter of the fixed pipe 40 can be replaced to be suitable for pipe diameters DN8 to DN65. Please also refer to Figure 7, but when changing the size of the fixed pipe 40, the second bracket 30 also needs to be adjusted and replaced with different sizes accordingly, so as to maintain the first bracket 20 and the second bracket 30 both at an obtuse angle of 140 degrees, so as to achieve the purpose of stable clamping.

[0036] A superconducting sheet 101 is further provided between the ultrasonic flowmeter 10 and the fixed pipe 40. Its main function is to measure the fixed pipe 40, which is equivalent to the probe of the existing flowmeter. This is a common setting method in the field, so it is not limited to the superconducting sheet 101 or the probe design.

[0037] As described above, regarding the detailed structure of the snap-locking structure of the ultrasonic flowmeter of the present invention, before installation and use, it is necessary to first confirm the cleanliness inside the fixed pipe 40 and clean the oil stains inside and outside the pipe. After clamping the fixed pipe 40 with the first bracket 20 and the second bracket 30 in sequence and then locking them, the superconducting sheet 101 is then arranged at the bottom of the ultrasonic flowmeter 10. Then, the ultrasonic flowmeter 10 is further locked to the first bracket 20 by means of the snap-locking structure 12 and the quick screw 14. At this time, the superconducting sheet 101 can effectively and closely fit on the outside of the fixed pipe 40. Subsequently, as long as the ultrasonic flowmeter 10 is connected by a cable, the power supply can be supplied and the flow rate can be monitored. The superconducting sheet 101 here is not limited to this implementation method, and the measurement method can also be changed by expanding the wire to accommodate more types of pipes. This is an application that can be easily changed by those familiar with the field, so it is not limited thereto.

[0038] In summary, the snap-locking structure of the ultrasonic flowmeter of the present invention effectively solves the problems of cumbersome installation and unstable fixation of the traditional ultrasonic flowmeter, and greatly improves the installation efficiency and use convenience. It is more suitable for fixed pipes of different sizes. With its unique design and excellent performance, it has a broad application prospect in the field of industrial automation.
