Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic flow meters, and in particular to an ultrasonic flow meter interference shielding device. Background Technology
[0002] Ultrasonic flow meters are commonly used flow measurement devices in industrial production, municipal water supply and other fields. Their core consists of a sensor body and a display host. The sensor body emits and receives ultrasonic signals, analyzes parameters such as the time difference of signal propagation in the fluid, calculates the fluid flow data, and feeds the results back to the display host in real time. This provides key data support for production control, resource metering and other work, and is widely used in flow monitoring scenarios in many industries such as petroleum, chemical, and water treatment.
[0003] However, existing ultrasonic flow meters lack effective interference shielding structures in practical applications. External electromagnetic interference can easily contact the sensor body, causing deviations in the sensor's data acquisition. At the same time, residual interference signals can also affect the normal operation of the display host, resulting in a decrease in flow monitoring accuracy. On the other hand, the installation design of the supporting shielding device is unreasonable, making it difficult to quickly complete the positioning and installation of the shielding device. Repeated adjustments are required to achieve stable installation, which prolongs the installation time. To address these issues, we propose an ultrasonic flow meter interference shielding device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: An ultrasonic flowmeter interference shielding device includes two shielding covers. Support plates are fixedly connected to the outer surfaces of both shielding covers. Shielding shells are fixedly connected to the upper surfaces of both support plates. A sensor body is disposed between the two shielding covers. A display host is fixedly installed at the top of the sensor body and is located between the two shielding shells. Two fixing seats are fixedly connected to the outer surface of one shielding cover. A threaded groove is formed on one side of each of the two fixing seats. Two fixing through plates are fixedly connected to the outer surface of one shielding cover. Fixing screws are provided on one side of each of the two fixing through plates, and the outer surface of the fixing screws is threaded to the inner wall of the threaded groove.
[0006] As a preferred technical solution of this application, the left and right ends of the sensor body are fixedly connected with flanges, and multiple connection holes are opened on the side of the two flanges that are far apart from each other.
[0007] As a preferred technical solution of this application, two positioning seats are fixedly connected to the outer surface of one of the shielding covers, and positioning holes are opened on one side of each of the two positioning seats.
[0008] As a preferred technical solution of this application, two positioning plates are fixedly connected to the outer surface of one of the shielding covers, and a positioning rod is fixedly connected to one side of each of the two positioning plates, and the outer surface of the positioning rod is in contact with the inner wall of the positioning hole.
[0009] As a preferred technical solution of this application, a transparent observation plate is fixedly embedded on one side of the shielding shell. The transparent observation plate is located on one side of the display host. The transparent observation plate is made of bulletproof glass and has a thickness of -mm.
[0010] As a preferred technical solution of this application, the inner walls of both shielding shells are fixedly connected with shielding cotton layers, and the outer surface of the shielding cover is sprayed with an anti-corrosion coating.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This device can directly block external interference signals from contacting the sensor body through the shielding outer cover. The shielding shell can absorb residual interference signals, reduce the impact of interference on the display host, and improve the accuracy and stability of flow data monitoring. In addition, the positioning rod of the positioning plate and the positioning hole at the positioning seat can quickly complete the initial positioning of the two shielding outer covers and two shielding shells. Furthermore, the fixing screws and threaded grooves can be used to achieve tight assembly, simplifying the installation process, reducing adjustment time, and improving the installation efficiency of the shielding device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4 In this utility model, an ultrasonic flowmeter interference shielding device includes two shielding covers 1. Support plates 2 are fixedly connected to the outer surfaces of both shielding covers 1. Shielding shells 3 are fixedly connected to the upper surfaces of both support plates 2. Both the shielding covers 1 and the shielding shells 3 are made of metal, such as common stainless steel, which has good conductivity and mechanical strength, effectively blocking external interference signals. Stainless steel also has excellent corrosion resistance. A sensor body 4 is located between the two shielding covers 1. A display host 5 is fixedly installed on the top of the sensor body 4. The display host 5 is located between the two shielding shells 3. Two fixed supports 3 are fixedly connected to the outer surface of one shielding cover 1. The two mounting bases 8 each have a threaded groove 14 on one side. Two fixing plates 7 are fixedly connected to the outer surface of a shielding cover 1. Each of the two fixing plates 7 has a fixing screw 9 on one side, and the outer surface of the fixing screw 9 is threaded to the inner wall of the threaded groove 14. By setting two shielding covers 1, an outer protective space can be provided for the sensor body 4, ensuring that the sensor body 4 can be stably placed between the two shielding covers 1. The two shielding shells 3 can make the display host 5 just between the two shielding shells 3. In addition, the two shielding covers 1 and the two shielding shells 3 can be installed and fixed by the cooperation of the threaded groove 14 of the mounting base 8 and the fixing screw 9 at the fixing plate 7.
[0019] As a preferred technical solution of this application, flanges 12 are fixedly connected to both the left and right ends of the sensor body 4. Multiple connection holes 13 are opened on the side of the two flanges 12 that are far apart from each other. Two positioning seats 11 are fixedly connected to the outer surface of a shielding cover 1. Positioning holes 15 are opened on one side of the two positioning seats 11. Two positioning plates 10 are fixedly connected to the outer surface of a shielding cover 1. Positioning rods 16 are fixedly connected to one side of the two positioning plates 10. The outer surface of the positioning rods 16 contacts the inner wall of the positioning holes 15. Through the cooperation of the positioning rods 16 at the positioning plates 10 and the positioning holes 15 at the positioning seats 11, the initial positioning of the two shielding covers 1 and the shielding shell 3 can be quickly completed, reducing the position adjustment time during assembly and improving installation efficiency. On the other hand, by setting flanges 12 and multiple connection holes 13, a standardized interface can be provided for the docking of the device with external pipelines, ensuring that the sensor body 4 can be stably connected to the fluid pipeline and ensuring the continuity of flow data acquisition.
[0020] As a preferred technical solution of this application, a transparent observation plate 6 is fixedly embedded on one side of the shielding shell 3. The transparent observation plate 6 is located on one side of the display host 5. The transparent observation plate 6 is made of bulletproof glass and has a thickness of 4-6mm. Shielding cotton layers are fixedly connected to the inner walls of both shielding shells 3. The outer surface of the shielding cover 1 is coated with an anti-corrosion coating. By setting a shielding cotton layer on the inner wall of the shielding shell 3, the absorption capacity of residual interference signals can be enhanced, and the display host 5 can be more comprehensively protected. Through the transparent observation plate 6, the operator can directly observe the data of the display host 5 without disassembling the device. In addition, the anti-corrosion coating on the outer surface of the shielding cover 1 can resist corrosive media in the industrial environment, extend the service life of the device, and reduce maintenance costs.
[0021] The working principle of this utility model is as follows: During installation, firstly, use the two positioning plates 10 on the surface of one shielding cover 1 to align the positioning rod 16 fixed on one side with the positioning hole 15 on the other shielding cover 1 and insert it to complete the initial positioning of the two shielding covers 1. At the same time, the sensor body 4 will be placed between the two shielding covers 1. Then, screw the fixing screw 9 into the inside of the threaded groove 14 to achieve the tight assembly of the two shielding covers 1 and the two shielding shells 3, which can wrap the sensor body 4 and the display host 5. During the shielding phase, the shielding cover 1 can block external interference signals from contacting the sensor body 4, and the shielding shell 3 absorbs residual interference signals to ensure that the display host 5 is not interfered with. At the same time, the transparent observation plate 6 of the shielding shell 3 can facilitate the staff to observe the data of the display host 5 without affecting the shielding effect.
