Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, and particularly relates to an ultrasonic flowmeter with a protection structure. Background Technique

[0002] As an advanced flow measurement device, the clamp-on ultrasonic flowmeter has many advantages.

[0003] Firstly, its installation and operation are extremely simple. Users do not need to break the pipe and stop production. They only need to clamp two card seats on both sides of the pipe surface and tighten the screws to complete the installation. The whole process is fast and efficient, greatly saving time and cost. This feature makes the clamp-on ultrasonic flowmeter particularly suitable for occasions where quick installation and replacement are required;

[0004] Secondly, the clamp-on ultrasonic flowmeter has high measurement accuracy and can accurately measure the flow of various media, especially performing well in small-diameter projects. The multi-pulse technology, signal digital processing technology and error correction technology it adopts ensure the accuracy and reliability of the measurement results;

[0005] In addition, the clamp-on ultrasonic flowmeter also has the advantages of strong anti-interference ability and fast response speed, and can adapt to various complex industrial site environments. At the same time, its modular design enables users to freely combine according to actual needs to meet the measurement requirements of different types and different flow ranges.

[0006] The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution: The flowmeter contains two seat bodies, one of which is integrated with the flowmeter. This seat body is connected to the other seat body by bolts. However, due to the vibration generated by the flow of the medium in the pipe, or when it is close to a pump or valve, certain vibrations will also be generated. These vibrations will be transmitted through the pipe to the screws on the seat body, resulting in the bolts becoming loose. When the bolts become loose, the stability of their connection will disappear, and there will be a gap between the fitting surface of the flowmeter and the pipe, leading to inaccurate detection or inability to detect, which brings trouble to the use. Content of the Utility Model

[0007] The main purpose of the utility model is to provide an ultrasonic flowmeter with a protection structure, which can effectively solve the problems in the background technique.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] An ultrasonic flowmeter with a protective structure includes a pipeline. One end of the outer wall of the pipeline is sleeved with a first seat body, and the other end of the outer wall of the pipeline is sleeved with a second seat body. A flowmeter is arranged on the side of the second seat body away from the first seat body. Four screw grooves are drilled on the side of the first seat body close to the second seat body. Bolt grooves are drilled at the positions of the second seat body corresponding to the screw grooves. Bolts are respectively inserted through the bolt grooves and inserted into the screw grooves and are threadedly connected with them. Pressure blocks are arranged on the outer sides of the first seat body between the bolt grooves. Outer plates are fixed at the positions of the pressure blocks corresponding to the bolt grooves. The outer plates are respectively inserted into the bolt grooves. Limiting plates are fixed at the top and bottom of the side wall of the outer plate close to the second seat body. Plate grooves are drilled on the side walls of the bolt grooves at the positions of the limiting plates. Large column grooves are drilled at the ends of the plate grooves away from the bolt grooves. Small column grooves are drilled at the ends of the large column grooves away from the plate grooves. Insertion columns are respectively inserted into the small column grooves. The bottoms of the insertion columns are inserted into the large column grooves. Outer circular plates are fixed at the bottoms of the ends of the insertion columns inserted into the large column grooves. Insertion rods are fixed at the ends of the outer circular plates away from the insertion columns. The limiting plates are inserted into the plate grooves with matching sizes. Plate holes are drilled at the positions of the limiting plates corresponding to the insertion rods. Springs are respectively embedded in the large column grooves.

[0010] Preferably, the ends of the outer plates close to the bolts are in contact.

[0011] Preferably, the insertion rods are respectively inserted into the plate holes of the limiting plates, and the outer diameter sizes of the insertion rods are respectively matched with the inner diameter sizes of the plate holes on the limiting plates.

[0012] Preferably, the springs are respectively sleeved on the outer walls of the ends of the insertion columns inside the large column grooves, and the springs are all tension springs.

[0013] Preferably, outer circular plates are fixed at the ends of the insertion columns outside the small column grooves, and the sides of the outer circular plates close to the second seat body are in contact.

[0014] Preferably, the outer diameter sizes of the insertion columns are respectively matched with the inner diameter sizes of the small column grooves. The ends of the springs are respectively in contact with the ends of the inner circular plates away from the insertion rods. The insertion columns are respectively slidably connected with the small column grooves.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] After the bolt passes through the bolt groove and is inserted into the screw groove and thread - connected, a primary connection is formed between the screw groove and the bolt groove. The outer plate at one end of the pressing block is inserted into the interior of the bolt groove and abuts against the head part of the bolt. The limiting plate will be inserted into the interior of the plate groove. Subsequently, the downward pressure of the spring on the inner circular plate will drive the insertion rod to be inserted into the plate hole of the limiting plate, thus forming a limit. When the thread loosens due to vibration, the limit of the insertion rod on the limiting plate can block the path of the bolt's outward movement by the outer plate, thereby forming an effect of preventing thread loosening. Finally, the limiting and protective effect on the flowmeter is achieved, avoiding the situation of inaccurate detection or inability to detect due to poor contact between it and the pipeline.

Detailed Embodiment

[0024] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0025] Such as Figures 1-6As shown in the figure, an ultrasonic flowmeter with a protective structure includes a pipeline 1. One end of the outer wall of the pipeline 1 is sleeved with a first seat body 2, and the other end of the outer wall of the pipeline 1 is sleeved with a second seat body 3. A flowmeter 4 is arranged on the side of the second seat body 3 away from the first seat body 2. Four screw grooves 21 are drilled on the side of the first seat body 2 close to the second seat body 3. Bolt grooves 31 are drilled at the positions of the second seat body 3 corresponding to the screw grooves 21. Bolts 5 are respectively inserted through the bolt grooves 31. One end of each bolt 5 passing through the bolt groove 31 is inserted into the screw groove 21 and is threadedly connected thereto. Pressure blocks 6 are arranged on the outer sides of the first seat body 2 between the bolt grooves 31. Outer plates 7 are fixed at the positions of the pressure blocks 6 corresponding to the bolt grooves 31. The outer plates 7 are respectively inserted into the bolt grooves 31. Limiting plates 8 are fixed at the top and bottom of the side wall of the outer plate 7 close to the second seat body 3. Plate grooves 32 are drilled on the side walls of the bolt grooves 31 at the positions of the limiting plates 8. Large column grooves 33 are drilled at one ends of the plate grooves 32 away from the bolt grooves 31. Small column grooves 34 are drilled at one ends of the large column grooves 33 away from the plate grooves 32. Insertion columns 9 are respectively inserted into the small column grooves 34. The bottoms of the insertion columns 9 are respectively inserted into the large column grooves 33. Outer circular plates 10 are fixed at the bottoms of one ends of the insertion columns 9 inserted into the large column grooves 33. Insertion rods 12 are fixed at one ends of the outer circular plates 10 away from the insertion columns 9. The limiting plates 8 are inserted into the plate grooves 32 with matching sizes. Plate holes are drilled on the limiting plates 8 at the positions of the insertion rods 12. Springs 13 are respectively embedded in the large column grooves 33.

[0026] Specifically, the ends of the outer plates 7 close to the bolts 5 are in contact with each other, which can resist the bolts 5.

[0027] Specifically, the insertion rods 12 are respectively inserted into the plate holes of the limiting plates 8, and the outer diameter sizes of the insertion rods 12 are respectively matched with the inner diameter sizes of the plate holes on the limiting plates 8, so as to avoid the situation that the limiting plates 8 move outward due to the size difference.

[0028] Specifically, the springs 13 are respectively sleeved on the outer walls of one ends of the insertion columns 9 located inside the large column grooves 33. The ends of the springs 13 are respectively in contact with one ends of the inner circular plates 11 away from the insertion rods 12. The springs 13 are all tension springs, so that the insertion rods 12 can be stably inserted into the plate holes of the limiting plates 8.

[0029] Specifically, outer circular plates 10 are fixed at one ends of the insertion columns 9 located outside the small column grooves 34. The sides of the outer circular plates 10 close to the second seat body 3 are in contact with each other. After the insertion rods 12 are inserted into the plate holes of the limiting plates 8, the outer circular plates 10 are in contact with the outer wall of the second seat body 3, and thus it can be judged whether the insertion rods 12 are accurately inserted into the plate holes of the limiting plates 8.

[0030] Specifically, the outer diameter sizes of the insertion columns 9 are respectively matched with the inner diameter sizes of the small column grooves 34, and the insertion columns 9 are respectively slidably connected with the small column grooves 34 to ensure the verticality of the lifting movement.

[0031] Working principle:

[0032] After the bolt 5 passes through the bolt slot 31 and is inserted into the thread groove 21 and threadedly connected, a primary connection is formed between the thread groove 21 and the bolt slot 31. The outer plate 7 at one end of the pressing block 6 is inserted into the interior of the bolt slot 31 and abuts against the head portion of the bolt 5. The limiting plate 8 will be inserted into the interior of the plate slot 32. Subsequently, the downward pressure of the spring 13 on the inner circular plate 11 will drive the insertion rod 12 to be inserted into the plate hole of the limiting plate 8, thus forming a limit. When the situation of wire loosening occurs due to vibration, the limit of the insertion rod 12 on the limiting plate 8 can cause the bolt 5 to be blocked by the outer plate 7 on the outward movement path, thereby forming an effect of preventing wire loosening. Finally, a limiting and protective effect on the flowmeter 4 is achieved, avoiding the situations of inaccurate detection or inability to detect due to poor contact between it and the pipeline 1.
