Description

Technical Field

[0001] This utility model relates to the field of ultrasonic energy meters, and in particular to an ultrasonic energy meter with strong applicability. Background Technology

[0002] With the increasing demand for energy metering and energy conservation management, ultrasonic energy meters are widely used in fluid energy metering applications such as centralized heating, central air conditioning systems, and hot water supply due to their advantages such as non-contact measurement, no mechanical wear, high accuracy, and low maintenance costs. Existing ultrasonic energy meters mainly measure the flow rate and temperature difference of the fluid, and combine the fluid thermodynamic parameters to calculate the heat or cold transferred, thereby achieving accurate measurement of energy consumption.

[0003] As disclosed in utility model patent CN219608279U, an ultrasonic energy meter that is easy to maintain includes: an ultrasonic energy meter; a first flange welded to both the left and right ends of the ultrasonic energy meter. A slot, a semi-cylindrical groove structure, is provided on the top surface of the outer wall of the first flange; a limiting rod is welded to the top surface of the outer wall of the second flange, and the limiting rod is engaged with the slot. When the limiting rod is engaged with the slot, the fixing holes on the second flange and the first flange are aligned. This improves installation efficiency and solves the problem that when the fixing bolts of the ultrasonic energy meter are damaged during maintenance, disassembly becomes difficult, thus affecting maintenance efficiency. Furthermore, structural improvements cannot achieve quick disassembly through other connections after the fixing bolts on the flange are damaged.

[0004] In the above-mentioned device, the cooperation between the slot and the limiting rod only achieves pre-positioning, and the actual fastening still relies on the bolts. The slot is a semi-cylindrical groove structure and does not have a locking function. When the bolts are loose, the flange may be misaligned due to the weight of the pipeline.

[0005] Therefore, it is necessary to provide a new, highly applicable ultrasonic energy meter to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the ultrasonic energy meter with strong applicability provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the auxiliary rod. Figure 3 for Figure 1 The diagram shows the structure of the positioning component. Figure 4 for Figure 1 The diagram shows the structural relationship between the rotating shaft and the mounting plate.

[0021] In the specific implementation process, such as Figure 1-2As shown, this utility model provides a highly applicable ultrasonic energy meter, including an ultrasonic energy meter 1; a first flange 3 is welded to both the left and right ends of the ultrasonic energy meter 1; a second flange 4 is fixedly connected to each first flange 3 by fixing bolts 8; both the second flange 4 and the first flange 3 have positioning grooves 20, and a positioning component is provided on one side of the positioning groove 20; a first connecting pipe 9 is welded to each second flange 4, and a second flange 4 is welded to one end of the outer side of each first connecting pipe 9; the two outer second flanges 4 are connected to the pipe... The flanges are connected, and the first connecting pipe 9 is connected to the ultrasonic energy meter 1. Each of the two first flanges 3 has three connecting holes 10 arranged in a fan-shaped array. An auxiliary rod 2 is inserted into each of the three connecting holes 10. The three auxiliary rods 2 together form the reinforcing structure of the ultrasonic energy meter 1. A second connecting pipe 5 is welded to each of the two outer second flanges 4. The second connecting pipe 5 is a cylindrical tubular structure. The second connecting pipe 5 is inserted into the pipe. The outer sides of the two second connecting pipes 5 are polished. After polishing, the outer sides of the two second connecting pipes 5 are arc-shaped structures.

[0022] It should be noted that the aforementioned versatile ultrasonic energy meter (ultrasonic energy meter 1, auxiliary rod 2, first flange 3, second flange 4, second connecting pipe 5, fixing bolt 8, first connecting pipe 9, and connecting hole 10) is a maintenance-friendly ultrasonic energy meter (ultrasonic energy meter, auxiliary rod, first flange, second flange, second connecting pipe, fixing bolt, first connecting pipe, and connecting hole) disclosed in CN219608279U. In this device, during maintenance, each first flange is fixedly connected to a second flange by fixing bolts, and each second flange is welded to a first connecting pipe. A second flange is welded to one end of each first connecting pipe, and the two outer second flanges are connected to flanges on the pipe. The first connecting pipe is connected to the ultrasonic energy meter. During maintenance, when the connection between the second flange and the flange on the pipe cannot be disassembled, the fixing bolts can be removed, facilitating maintenance. Since both first flanges have three connection holes arranged in a fan-shaped array, and an auxiliary rod is inserted into each of these holes, the three auxiliary rods together form a reinforced structure for the ultrasonic energy meter, reducing the likelihood of breakage under stress. Furthermore, since both outer second flanges are welded with a second connecting pipe, which is a cylindrical tubular structure, and is inserted into the pipe, the strength of the connection between the first connecting pipe and the pipe is increased. The mechanisms in this device are identical in principle and operation to a previously disclosed easy-to-maintain ultrasonic energy meter, allowing the device to effectively reduce the likelihood of breakage under stress by using the auxiliary rods.

[0023] In the specific implementation process, refer to Figure 3 As shown, this utility model provides a highly applicable ultrasonic energy meter. The positioning assembly includes a mounting plate 11, a positioning post 12, a mounting bracket 13, a rotating shaft 14, a pressing plate 15, a sliding rod 16, a spring 17, a limiting plate 18, and a locking rod 19. Two positioning brackets are fixedly connected to the top of the second flange 4. A rotating shaft 14 is mounted on the inner wall of the two mounting brackets 13. The outer wall of the rotating shaft 14 is slidably connected to the inner wall of one end of the mounting plate 11. The bottom of the other end of the mounting plate 11 is fixedly connected to one end of the positioning post 12. The other end of the positioning post 12 is slidably connected to the inner wall of two positioning grooves 20. The inner walls of the two positioning brackets are rotatably connected to the outer wall of one end of the rotating shaft 14. The mounting bracket 16... The two ends of 3 are slidably connected to the outer walls of the two sliding rods 16. One end of the two sliding rods 16 is fixedly connected to the bottom of the pressing plate 15. The bottom of the pressing plate 15 is fixedly connected to the top of the spring 17. The bottom of the spring 17 is fixedly connected to the top of the mounting bracket 13. The sliding rods 16 are located in the inner wall of the spring 17. The other end of the two sliding rods 16 is fixedly connected to the top of the limiting plate 18. The top center of the limiting plate 18 is fixedly connected to one end of the locking rod 19. One end of the rotating shaft 14 is provided with a locking groove. The outer wall of the locking rod 19 is slidably connected to the inner wall of the locking groove. The inner walls of both ends of the second connecting pipe 5 are provided with threaded grooves 6. The threaded grooves 6 are threadedly connected to the reducing joints 7.

[0024] It should be noted that one end of the mounting plate 11 slides on the rotating shaft 14, and its inner wall has a groove that mates with the spline on the outer wall of the rotating shaft 14. The other end is connected to the positioning post 12, which serves to transmit force. The positioning post 12 is slidably connected to the inner wall of the positioning groove 20 to ensure precise alignment between the second flange 4 and the first flange 3. The mounting bracket 13 is fixed to the top of the second flange 4, supporting the entire positioning assembly. The rotating shaft 14 allows the mounting plate 11 to rotate around it, and its outer wall has a spline at the connection with the mounting plate 11, which mates with the groove on the inner wall of the mounting plate 11 to facilitate adjustment of the position of the positioning post 12. The pressing plate 1... 5. The user unlocks the locking lever 19 by pressing this plate; the two ends of the sliding lever 16 are fixed between the pressing plate 15 and the limiting plate 18 respectively, providing guidance and limiting the movement range of the pressing plate 15; the spring 17 provides a restoring force for the pressing plate 15, ensuring that the locking lever 19 can automatically insert into the locking groove after the pressing plate is released; the limiting plate 18 is fixed to the other end of the sliding lever 16 to prevent excessive compression of the spring 17; the locking lever 19 is inserted into the locking groove on the rotating shaft 14 to ensure that the positioning pin 12 will not accidentally slide out of the positioning groove 20; the spring 17 is a stainless steel compression spring with a preload ≥3mm and a lifespan ≥100,000 cycles.

[0025] The working principle of this utility model is as follows: The first flange 3 and the second flange 4 are tightly connected by fixing bolts 8 to ensure a stable connection between the ultrasonic energy meter 1 and the pipeline or other equipment. The positioning pin 12 is slidably connected to the inner wall of the two positioning grooves 20 to ensure precise alignment between the second flange 4 and the first flange 3. The locking rod 19 is inserted into the locking groove on the rotating shaft 14 to ensure that the positioning pin 12 will not accidentally slide out of the positioning groove 20, thereby ensuring a stable connection between the flanges. When the user manually presses the pressing plate 15, the spring 17 is compressed, and the pressing plate 15 drives the sliding rod 16 to move downward. As the pressing plate 15 moves downward, the locking rod 19 slides out of the locking groove of the rotating shaft 14, releasing the locking of the positioning pin 12. The positioning pin 12 can slide freely and is no longer locked. The rod 19 is restricted; the mounting plate 11 is manually rotated (through the rotating shaft 14) to pull the rotating shaft 14 out of the inner wall of the mounting bracket 13. At this time, the mounting plate 11 is raised so that the positioning pin 12 is disengaged from the positioning groove 20, thereby separating the second flange 4 from the first flange 3. This step allows the user to perform maintenance or replacement operations. The second flange 4 is aligned with the first flange 3 so that the positioning pin 12 can slide smoothly into the positioning groove 20. The pressing plate 15 is released, and the spring 17 pushes the pressing plate 15 back, which drives the locking rod 19 to re-insert into the locking groove of the rotating shaft 14 to complete the locking. The inner walls of both ends of the second connecting pipe 5 are provided with threaded grooves 6. The reducing joint 7 is connected to the threaded groove 6 by threads. Different sizes of reducing joints can be selected according to actual needs to adapt to different pipe diameters.

[0026] This versatile ultrasonic energy meter has the following advantages: the positioning pin 12 and the positioning groove 20 work together to ensure precise alignment between flanges, avoiding leakage or inaccurate measurement problems caused by installation errors; the pressing plate 15 and the spring 17 simplify the locking and unlocking process, allowing for quick disassembly and assembly without complicated tools, reducing the difficulty of operation; after the locking rod 19 is inserted into the locking groove on the rotating shaft 14, it effectively prevents accidental loosening or falling off and flange misalignment caused by pipeline gravity when bolts are loose, improving the safety of the system.

[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
