However, in actual use, the installation method of using cable ties to bundle pipes and adjusting the position of the acoustic transmitter through a sliding structure is relatively complicated and requires certain operating skills and experience. For users who are not familiar with the equipment, they will encounter difficulties during the installation process, affecting the installation efficiency. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides an anti-interference ultrasonic flowmeter, which aims to improve the problem that the installation of ultrasonic flowmeters in the prior art is relatively complicated.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an interference-proof ultrasonic flowmeter, including a flowmeter, the rear side of the flowmeter is fixedly connected to a mounting plate 1, the rear side of the mounting plate 1 is provided with a mounting plate 2, the outer walls of the mounting plate 1 and the mounting plate 2 are fixedly connected with a strong magnetic block, the adjacent sides of the mounting plate 1 and the mounting plate 2 are provided with multiple sliding grooves, the inner sides of the multiple sliding grooves are slidably connected with sliding columns, the front and rear ends of the multiple sliding columns are threadedly connected with nuts, and the adjacent sides of the mounting plate 1 and the mounting plate 2 are provided with an adjustment mechanism.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the latch is slidably connected to the inner side of the positioning hole.

[0021] Through the above technical solution: when the pin is inserted into the positioning hole, it can play a certain fixing role, preventing the mounting plate 1 and the mounting plate 2 from relative displacement after installation. Even in the case of water flow impact or external vibration, the cooperation between the pin and the positioning hole can maintain the stability of the mounting plate, thereby ensuring the measurement accuracy of the flow meter.

[0024] Through the above technical solution, the grooves on the inner sides of the first and second mounting plates can better fit the shape of the pipeline, making the contact between the mounting plates and the pipeline closer.

[0025] As a further description of the above technical solution:

[0026] The front and rear ends of the outer walls of the plurality of sliding posts are each provided with a first threaded hole, and the inner sides of the plurality of nuts are each provided with a second threaded hole.

[0027] Through the above technical solution: through the cooperation of threaded hole one and threaded hole two, the nut can be firmly screwed on the sliding column, effectively fixing the mounting plate one and the mounting plate two. After the flow meter is installed on the pipeline, even if it is affected by water impact and external vibration, it can ensure that the mounting plate will not easily separate from the sliding column, thereby ensuring the installation stability of the flow meter.

[0028] The utility model has the following beneficial effects:

[0029] 1. In the present invention, the initial positioning of the installation is completed by the pin and the positioning hole, and the strong magnetic block is used to attract the mounting plate 1 and the mounting plate 2 to each other. At the same time, a sliding column is provided which can move in the slide groove to complete the automatic engagement. There is no need to use the traditional fixing method of the cable tie, which makes the installation more convenient and quick, and also avoids the trouble caused by the cable tie being too long or too short.

[0030] 2. In the present invention, the elastic pad and the mounting plate can be quickly fixed and disassembled by cooperating with the adhesive block 1 and the adhesive block 2, so that elastic pads of appropriate size and width can be selected for replacement according to pipes of different diameters and specific installation requirements, thereby improving the adaptability of the flow meter to different working conditions.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3, the utility model provides an embodiment: an anti-interference ultrasonic flowmeter, including a flowmeter 1, the rear side of the flowmeter 1 is fixedly connected to a mounting plate 1 3, the rear side of the mounting plate 1 3 is provided with a mounting plate 2 4, the outer walls of the mounting plate 1 3 and the mounting plate 2 4 are fixedly connected with a strong magnetic block 11, the adjacent sides of the mounting plate 1 3 and the mounting plate 2 4 are provided with a plurality of slide grooves 5, the inner sides of the plurality of the slide grooves 5 are slidably connected with a slide column 6, the front and rear ends of the plurality of the slide columns 6 are threadedly connected with a nut 8, the adjacent sides of the mounting plate 1 3 and the mounting plate 2 4 are provided with an adjustment mechanism 2 The front side of the flow meter 1 is provided with a display screen 12, and the outer wall of the flow meter 1 is connected to a connection port 13; the outer walls of the multiple nuts 8 are provided with anti-slip grooves 10, and the outer walls of the nuts 8 are made of silicone material; a pipe 16 is provided at the inner groove of the mounting plate 1 3 and the mounting plate 2 4, and the adjacent sides of the mounting plate 1 3 and the mounting plate 2 4 are slidably connected to the outer wall of the pipe 16; the rear side of the mounting plate 1 3 is fixedly connected to a plurality of latches 14, and the rear side of the mounting plate 2 4 is provided with a plurality of positioning holes 15; the outer wall of the latch 14 is slidably connected to the inner side of the positioning hole 15;

[0040] Specifically, the slide column 6 can slide smoothly in the slide groove 5. Through the strong magnetic blocks 11 installed on the mounting plate 1 3 and the mounting plate 2 4, the two mounting plates can attract each other and automatically engage. This strong magnetic block 11 uses the characteristics of magnetism to quickly adsorb the two mounting plates on the pipe 16, thereby eliminating the tedious steps of using traditional cable ties to fix. This innovative fixing method not only greatly improves the convenience and speed of the installation process, but also ensures the firmness and reliability of the installation. In order to further ensure the accuracy of the relative position of the mounting plate 1 3 and the mounting plate 2 4 during the installation process, the structure of the positioning hole 15 and the pin 14 is added to make the entire installation process more accurate and correct. In addition, the flow meter 1 can display the measurement results in real time through its display screen 12, which is convenient for users to intuitively understand the flow information, thereby better monitoring and management of the flow.

[0041] Refer to the attached Figure 5 The adjustment mechanism 2 includes an elastic pad 201, which is arranged on the rear side of the mounting plate 3, and an elastic pad 202 is arranged on the front side of the mounting plate 4. The elastic pad 201 and the elastic pad 202 are fixedly connected to the side away from each other with an adhesive block 203, and the inner sides of the mounting plate 3 and the mounting plate 4 are fixedly connected with an adhesive block 204;

[0042] Specifically, after installation, elastic pad 1 201 and elastic pad 2 202 are attached to the outer wall of pipe 16, playing a certain buffering role. When water flow impact or external vibration occurs, the impact on flow meter 1 can be reduced, the precision components inside the flow meter are protected, and the stability and service life of flow meter 1 are improved. Before installation, due to the presence of adhesive block 1 203 and adhesive block 2 204, elastic pad 1 201 and elastic pad 2 202 can be easily peeled off from the mounting plate, which facilitates the selection and replacement of elastic pads. This adhesive fixing method does not require the use of tools, is simple and quick to operate, and improves installation efficiency. At the same time, elastic pads of appropriate size and width can be selected for replacement according to the diameter of pipe 16, thereby improving the adaptability of flow meter 1 to different pipe diameters, so that flow meter 1 can be widely used in various pipeline systems.

[0043] Refer to the attached Figure 4 , the front and rear ends of the outer walls of the plurality of sliding posts 6 are each provided with a threaded hole 7, and the inner sides of the plurality of nuts 8 are each provided with a threaded hole 9;

[0044] Specifically, threaded holes 1 7 are provided at the front and rear ends of the outer wall of the slide post 6, and corresponding threaded holes 2 9 are also provided on the inner side of the nut 8. Through the mutual cooperation of these two sets of threaded holes, the slide post 6 can be effectively positioned and fixed. In this way, the mounting plate 1 3 and the mounting plate 2 4 will not easily detach from the slide post 6 during use, thereby ensuring the stability and safety of the entire device.

[0045] Working principle: First, loosen the nut 8. Since the slide post 6 is threadedly connected to the nut 8, after loosening the nut 8, the slide post 6 can move freely in the slide groove 5. Therefore, when the nut 8 is loosened, pull the two mounting plates in two opposite directions to separate the mounting plate 1 3 and the mounting plate 2 4. Then, place the adjacent sides of the mounting plate 1 3 and the mounting plate 2 4 on the outer wall of the pipe 16, and ensure that the pin 14 can be accurately aligned with the positioning hole 15. This can play a role in preliminary positioning and ensure that the relative positions of the mounting plates 1 3 and the mounting plates 2 4 are accurate during the installation process. At the same time, insert the slide post 6 into the slide groove 5 to prepare for subsequent fixation and adjustment. Through the strong magnetic blocks 11 installed on the mounting plates 1 3 and the mounting plates 2 4, the mounting plates 1 3 and the mounting plates 2 4 are attracted to each other. The flow meter 1 is connected to the pipe 16 through the connecting port 13, and starts to measure the fluid flow in the pipe 16. The measurement result is displayed in real time on the display screen 12 for the convenience of observation and analysis by the user. After installation, the elastic pad 1 201 and the elastic pad 2 202 fit the outer wall of the pipe 16, which plays a certain buffering role. At the same time, before installation, due to the presence of the adhesive block 1 203 and the adhesive block 2 204, the elastic pad 1 201 and the elastic pad 2 202 can be easily peeled off from the mounting plate. At this time, according to the diameter of the pipe 16 and the installation requirements, an elastic pad of appropriate size and width can be selected for replacement, and the adhesive block 1 203 on the new elastic pad can be adhered and fixed to the adhesive block 2 204 on the mounting plate again.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
