Description

Technical Field

[0001] The utility model relates to the technical field of level gauges, and specifically, to a radar level gauge. Background Art

[0002] In the fields of industrial production and warehousing management, etc., as an important measuring device, the radar level gauge is widely used in the precise measurement of liquid level, material level, etc. It determines the level height by emitting radar waves and receiving reflected waves, providing key data support for the monitoring and management of the production process. However, there is a prominent problem in many radar level gauges on the market during use, that is, the indicator is inconvenient to adjust. As an important part of the radar level gauge, the main function of the indicator is to intuitively display the measured level information to the operator so that they can timely understand the level situation and make corresponding decisions.

[0003] On the one hand, when the radar level gauge is installed in different positions and environments, due to the limited fixed position or adjustment method of the indicator, the viewing angle may be poor. For example, for a radar level gauge installed in some narrow spaces or at high places, it may be difficult for the operator to clearly see the readings on the indicator from a suitable angle, which brings great difficulties to the daily level observation. On the other hand, when maintaining and overhauling the radar level gauge, the inconveniently adjustable indicator also brings many inconveniences. When it is necessary to check, calibrate or replace the internal components of the radar level gauge, the operator may need to spend a lot of time and effort to adjust their position in order to see the status information on the indicator clearly or perform corresponding operations. This not only reduces the maintenance efficiency, but also increases the maintenance cost and risk. Content of the Utility Model

[0033] Referring to Figure 1 , an embodiment of the present invention provides a radar level gauge, which includes an indicator 1. The indicator 1 is arranged on a adapter 2. The adapter 2 has a threaded through hole 201. The adapter 2 is rotatably arranged on an extension section 3. The extension section 3 has an annular groove 301. A setscrew 4 is threadedly arranged in the threaded through hole 201, and the setscrew 4 abuts or does not abut against the wall of the annular groove 301.

[0034] In this embodiment, the indicator 1 is arranged on the adapter 2 which has a threaded through hole 201. The extension section 3 is used to adapt to different environmental conditions, and the adapter 2 is rotatably arranged on the extension section 3. With such a design, when it is necessary to replace the indicator 1 or adjust the angle of the indicator 1 for easy observation by the operator, the adapter 2 can be easily rotated so that the indicator 1 can achieve a 360-degree rotation. In the actual industrial production environment, there may be various obstacles or special installation position requirements. At this time, the length of the extension section 3 can be adjusted according to the specific situation to ensure that the operator can accurately read the measured liquid level. When the position of the indicator 1 is not conducive to observation or needs to be replaced, the operator can directly rotate the adapter 2 after adjusting the position of the setscrew 4 to adjust the indicator 1 to an appropriate angle or perform the replacement operation. When installing the radar level gauge in a relatively narrow space, due to space limitations, the operator may not be able to directly observe the display of the indicator 1. At this time, by rotating the adapter 2, the indicator 1 is rotated to an angle that is convenient for observation, greatly improving the convenience of operation.

[0035] The design that the indicator 1 can rotate 360 degrees greatly improves the convenience of observation by the operator. No matter where the radar level gauge is installed, the best observation angle can be found by rotating the indicator 1 to ensure that the operator can obtain the liquid level information in a timely and accurate manner. The setting of the extension section 3 enables the radar level gauge to adapt to different environmental conditions. Whether it is in a storage tank with a relatively high height or a container with a narrow space, the length of the extension section 3 can be adjusted to meet the measurement requirements, improving the versatility of the radar level gauge. This design structure is simple and easy to operate. When it is necessary to replace the indicator 1 or adjust the angle, no complex tools and operation steps are required, saving time and labor costs. It improves the reliability and stability of the radar level gauge. Since it can be adjusted according to the actual situation, the radar level gauge can better adapt to various working environments, reducing the possibility of measurement errors and failures caused by inappropriate installation positions or poor observation angles.

[0036] Furthermore, it further includes an upper electromagnetic coupler 5 arranged at the lower end of the extension section 3 and a lower electromagnetic coupler 6 arranged on the upper electromagnetic coupler 5.

[0037] In this embodiment, the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 cooperate with each other to achieve signal transmission or energy transfer. During the operation of the radar level gauge, it is necessary to transmit the measured level information to an external device for processing and display. The upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 can transmit the level information in a wireless form through electromagnetic induction, avoiding the wiring trouble and signal interference problems caused by traditional wired connections. For example, in a chemical production workshop, this radar level gauge is used to measure the liquid level in a storage tank. The combination of the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 can quickly and accurately transmit the liquid level information to the monitoring device in the control room, facilitating the operator to grasp the liquid level situation in the storage tank in real time and make timely production adjustments. At the same time, the signal can be synchronously transmitted to the indicator 1 to ensure that the material level can be judged in real time both on-site and in the central control. The setting of the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 provides a convenient signal transmission method for the radar level gauge. Through electromagnetic coupling, wireless transmission can be achieved, reducing the wiring cost and maintenance workload, and improving the reliability and stability of the system. The electromagnetic coupler has a high transmission efficiency and anti-interference ability. In a complex industrial environment, it can effectively avoid the interference of other electromagnetic signals and ensure the accurate transmission of the level information. This design makes the installation and use of the radar level gauge more flexible and convenient. Without considering the limitations of wired connections, the installation position can be adjusted according to actual needs, improving the adaptability of the device.

[0038] Further, it further includes a connecting piece 7. The connecting piece 7 is threadedly arranged on the extension section 3. The connecting piece 7 and the extension section 3 form an installation space 701. Both the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 are arranged in the installation space 701. A pressing ring 8 is arranged in the installation space 701. The upper electromagnetic coupler 5 is pressed on the pressing ring 8. The lower electromagnetic coupler 6 is arranged on the pressing ring 8. The pressing ring 8 is located between the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6.

[0039] In this embodiment, the connecting member 7 is threadedly arranged on the extension section 3, forming an installation space 701 with the extension section 3. Both the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 are arranged in this installation space 701. The pressing ring 8 is also arranged in the installation space 701. The upper electromagnetic coupler 5 is pressed on the pressing ring 8, and the lower electromagnetic coupler 6 is arranged on the pressing ring 8. The pressing ring 8 is located between the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6. In practical applications, when it is necessary to install the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6, first unscrew the connecting member 7 from the extension section 3, then place the lower electromagnetic coupler 6 at a suitable position in the installation space 701, then put in the pressing ring 8, then install the upper electromagnetic coupler 5 so that it is pressed on the pressing ring 8, and then screw the connecting member 7 onto the extension section 3 to form the installation space 701. This can ensure that the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 are stably fixed in the installation space 701 and will not loosen or shift due to external vibration or other factors. The design of the connecting member 7 and the pressing ring 8 can effectively fix the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6, ensuring that they can function properly during operation and accurately transmit signals. The installation space 701 formed by the connecting member 7 and the extension section 3 provides a stable installation environment for the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6. This design can prevent the electromagnetic coupler from being affected by the external environment, improving the reliability and stability of the device. The setting of the pressing ring 8 plays a role in fixing and pressing the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6. It can ensure that the electromagnetic couplers are closely attached in the installation space 701 without looseness or gaps, thus ensuring the accuracy and stability of signal transmission. The threadedly connected connecting member 7 makes the installation and disassembly more convenient and fast. When it is necessary to repair or replace the electromagnetic coupler, the connecting member 7 can be easily unscrewed from the extension section 3 for corresponding operations.

[0040] Further, it further includes a sealing ring 9. The sealing ring 9 is arranged in the installation space 701, and the pressing ring 8 is pressed on the sealing ring 9.

[0041] In this embodiment, the sealing ring 9 is disposed in the installation space 701, and the pressing ring 8 is pressed on the sealing ring 9. When the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 are installed, first place the sealing ring 9 at a suitable position in the installation space 701, and then place the pressing ring 8. The pressing ring 8 presses on the sealing ring 9, causing the sealing ring 9 to be tightly compressed, playing a sealing role. This can prevent external dust, moisture or other impurities from entering the installation space 701 and affecting the normal operation of the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6. The presence of the sealing ring 9 can effectively prevent moisture from entering the installation space 701, protect the electromagnetic coupler from the influence of a humid environment, and ensure that the device can operate stably and reliably. The setting of the sealing ring 9 improves the sealing performance of the radar level gauge. In various harsh working environments, it can effectively prevent external impurities from entering the installation space 701, protect the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 from damage, and extend the service life of the device. The pressing ring 8 is pressed on the sealing ring 9 to ensure the sealing effect of the sealing ring 9. The pressure of the pressing ring 8 enables the sealing ring 9 to closely fit on the inner wall of the installation space 701, forming an effective sealing barrier. The material of the sealing ring 9 usually has good elasticity and corrosion resistance, and can adapt to different working environments and temperature conditions. This enables the radar level gauge to maintain good sealing performance under various complex working conditions.

[0042] Furthermore, the pressing ring 8, the sealing ring 9, the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6 form a pressure isolation layer for isolating the pressures on the upper and lower sides of the upper electromagnetic coupler 5 and the lower electromagnetic coupler 6.

[0043] In this embodiment, the pressure isolation layer makes it possible to replace the indicator 1 in a pressurized environment, greatly improving the safety of operation. In the traditional situation, if the indicator 1 needs to be replaced, usually the equipment needs to be shut down and the pressure released first, which is not only time-consuming and laborious, but also may cause safety accidents due to improper operation. With the pressure isolation layer, the operator can replace the indicator 1 while the equipment maintains a certain pressure, without the need for complex shutdown and pressure relief operations, greatly reducing the safety risk. For many continuous industrial processes, shutting down the equipment to replace the indicator 1 will cause production interruption and huge economic losses. The existence of the pressure isolation layer allows the indicator 1 to be replaced under pressure, which means that the maintenance and replacement of the indicator 1 can be completed without affecting production. This can minimize the time of production interruption, improve production efficiency and economic benefits. By enabling the replacement of the indicator 1 under pressure, the pressure isolation layer helps to improve the overall reliability of the radar level gauge. When the indicator 1 fails or needs to be upgraded, it can be replaced in time without delaying the repair due to concerns about pressure problems. This enables the equipment to always maintain a good working state, improving the accuracy and stability of measurement. The design of the pressure isolation layer makes the operation of replacing the indicator 1 under pressure more convenient. The operator does not need to perform complex pressure control and safety protection measures, and only needs to operate according to specific steps to complete the replacement of the indicator 1. This not only saves time and labor costs, but also improves work efficiency. For example, in the petrochemical industry, radar level gauges are often used to measure the liquid level in storage tanks. Since the production process cannot be interrupted, the indicator 1 needs to be replaced under pressure. The existence of the pressure isolation layer enables the operator to quickly and safely complete the replacement of the indicator 1 without affecting production, ensuring the smooth progress of production.

[0044] Furthermore, it further includes a seal 10. The seal 10 is arranged on the extension section 3, and the adapter 2 is pressed on the seal 10.

[0045] In this embodiment, when the adapter 2 is installed on the extension section 3, by pressing on the seal 10, a sealing structure is formed. This seal 10 can effectively prevent external dust, moisture or other impurities from entering the interior of the radar level gauge, protecting the internal electronic components and sensors from damage. In a harsh industrial environment, there is a large amount of dust and moisture. Without the seal 10, these impurities may enter the radar level gauge, affecting its measurement accuracy and reliability. With the seal 10 and the adapter 2 pressed on the seal 10, it can effectively block the intrusion of external impurities, ensuring that the radar level gauge can work normally in a harsh environment.

[0046] The seal 10 improves the protection performance of the radar level gauge. It can prevent external dust, moisture, corrosive gases, etc. from damaging the electronic components and sensors inside the device, and extends the service life of the device. The sealing structure ensures the accuracy of measurement. If impurities enter the radar level gauge, it may interfere with the operation of the sensor and lead to inaccurate measurement results. The presence of the seal 10 can ensure that the sensor works in a relatively clean and stable environment, improving the measurement accuracy and reliability. The design of pressing the adapter 2 on the seal 10 is simple and reliable. This structure is easy to install and maintain, and can maintain good sealing performance during use.

[0047] Furthermore, the indicator 1 is inserted into the adapter 2.

[0048] In this embodiment, the indicator 1 is connected to the adapter 2 by insertion, and this connection method is simple and convenient. When it is necessary to replace the indicator 1 or perform maintenance, the indicator 1 can be easily pulled out of the adapter 2, and then a new indicator 1 can be inserted or maintenance operations can be carried out. At the production site, the indicator 1 of the radar level gauge fails. Since the indicator 1 is inserted into the adapter 2, the maintenance personnel can quickly pull out the faulty indicator 1 and then insert a spare indicator 1, enabling the radar level gauge to resume normal operation as soon as possible and reducing the production interruption time. The insertion connection method makes the installation and disassembly of the indicator 1 very convenient. There is no need to use complex tools and connection methods, and only by inserting the indicator 1 into the adapter 2 can the installation be completed, greatly improving the work efficiency. This design facilitates the replacement and maintenance of the indicator 1. When the indicator 1 fails or needs to be upgraded, it can be quickly replaced, reducing the maintenance cost and time. The insertion connection method can ensure the stable and reliable connection between the indicator 1 and the adapter 2. Under normal working conditions, the indicator 1 will not easily loosen or fall off, ensuring the measurement accuracy and stability of the radar level gauge.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
