[0022] 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.

[0023] Please see Figure 1-4A radar level gauge includes a level gauge body 1, a mounting plate 2, and a mounting base 3. The mounting plate 2 is installed on the bottom outer wall of the level gauge body 1. The top of the mounting base 3 has a mounting groove 4. Telescopic grooves 5 are formed on the front and rear side walls of the mounting groove 4. U-shaped blocks 6 are slidably installed within the two sets of telescopic grooves 5. L-shaped grooves 7 are formed on the front and rear ends of the mounting plate 2. Locking grooves 8 are formed at the ends of the two sets of L-shaped grooves 7 away from the center of the mounting plate 2. Locking blocks 9 are installed on the inner side walls of the two sets of U-shaped blocks 6. The locking blocks 9 are adapted to the locking grooves 8. A sliding groove 10 is formed on one side wall of the telescopic groove 5. A spring 11 is provided within the sliding groove 10. A sliding plate 12 is installed on the supporting end of the spring 11. The sidewalls of the sliding plate 12 and the sidewalls of the U-shaped blocks 6 are fixedly connected. Support rods 13 are installed at the ends of both sets of sliding plates 12 away from the springs 11. The two sets of support rods 13 extend through the sliding grooves 10 and beyond the mounting base 3. Guide mechanisms are installed at both ends of the mounting plate 2. In this embodiment, when the radar level gauge body 1 needs to be installed, the mounting base 3 is first pre-installed on the equipment to be detected, such as a storage tank, reaction vessel, or silo. The two sets of springs 11 support the sliding plate 12 in a supported state. The two sets of U-shaped blocks 6 are located in the two sets of telescopic grooves 5. Simultaneously, the two sets of support rods 13 are manually pressed, and the two sets of support rods 13 simultaneously apply force to the two sets of sliding plates 12. The two sets of sliding plates 12 drive the two sets of U-shaped blocks 6. The U-shaped block 6 slides out of the telescopic groove 5, and the two sets of sliding plates 12 compress the springs 11 in the two sets of sliding grooves 10. At the same time, the mounting plate 2 at the bottom of the level gauge body 1 is aligned with the mounting groove 4, and the mounting plate 2 is guided into the mounting groove 4 by the guide mechanism. When the mounting plate 2 enters the mounting groove 4, the end of the U-shaped block 6 away from the sliding plate 12 enters the L-shaped groove 7 below the mounting plate 2, and the locking block 9 enters the L-shaped groove 7 at the same time. At this time, the two sets of support rods 13 are released, and the support rods 13, i.e., the sliding plate 12, lose their support force. The springs 11 attempt to return to their original state, causing the two sets of sliding plates 12 to drive the two sets of U-shaped blocks 6 to move to both ends at the same time. The two sets of locking blocks 9 enter the locking grooves 8 of the two sets of U-shaped blocks 6. At this time, under the support of the two sets of springs 11, In this state, the mounting plate 2 is locked, meaning the level gauge body 1 is locked onto the mounting base 3. With the power connected, the target device can be detected for level using radar (the radar detection technology for the level gauge body 1 is well-known to those skilled in the art and will not be described in detail here). When it is necessary to disassemble the level gauge body 1, simply press both sets of support rods 13 simultaneously, causing the slide plate 12 to compress the spring 11, which in turn moves the two sets of U-shaped blocks 6 towards the center, disengaging the locking block 9 from the locking groove 8. At this point, the level gauge body 1 can be manually disengaged upwards, unlocking it. Because of the spring-driven locking mechanism, the installation and disassembly process is very simple, requiring no additional tools and allowing for quick operation, greatly improving work efficiency.The design of locking block 9 and locking groove 8 ensures the stability of the level gauge body 1 on the mounting base 3, reducing the risk of equipment loosening due to vibration or other external factors. Springs, as common elastic elements, are widely used in the mechanical field. Their basic principles and usage are existing technology. Springs are typically made of stainless steel (such as 304, 316), chrome vanadium spring steel (such as 50CrVA), or piano wire, etc., which can maintain elastic recovery ability after long-term repeated deformation, avoid plastic deformation, and can be used for a long time.

[0024] Preferably, in this embodiment, a pressing plate 14 is installed at the end of each of the two sets of support rods 13 away from the slide plate 12. A square groove 15 is provided at both the front and rear ends of the mounting base 3. The square groove 15 is adapted to the pressing plate 14. The pressing plate 14 increases the contact area between the operator and the support rod 13. When installing and disassembling the radar level gauge body 1, the operator does not need to press the thinner support rod 13 directly with their fingertips, but can press the pressing plate 14 with their palm or fingers over a large area, reducing local pressure on the hand and making the operation more comfortable and effortless. The pressing plate 14 makes it easier to find the point of force application, reducing the difficulty of operation and further improving the convenience of installation and disassembly. The design of the square groove 15 adapting to the pressing plate 14 ensures that the pressing plate 14 can be precisely embedded in the square groove 15 when locked, remaining flush with the surface of the mounting base 3. This prevents foreign objects from entering and affecting the normal operation of components such as the spring 11 and slide plate 12, ensuring the stability and reliability of the entire locking mechanism and extending the service life of the radar level gauge mounting structure.

[0025] Preferably, in this embodiment, a guide groove 16 is provided at the end of the telescopic groove 5 away from the sliding groove 10, and a guide rod 17 is fixedly installed in the guide groove 16. A guide block 18 is installed at the end of the U-shaped block 6 away from the sliding plate 12. The guide block 18 is slidably connected to the guide rod 17. When the U-shaped block slides in the telescopic groove 5, the guide block 18 can move smoothly along the guide rod 17, thereby guiding the movement of the U-shaped block. The cooperation between the guide rod 17 and the guide block 18 provides precise guidance for the sliding of the U-shaped block, limiting the possible lateral swaying or deviation of the U-shaped block in the telescopic groove 5. During the process of pressing the support rod 13 to drive the U-shaped block to extend and retract, the guide block 18 slides along the guide rod 17 to ensure that the U-shaped block always moves in the predetermined direction, so that the locking block 9 can be accurately aligned and cooperate with the locking groove 8.

[0026] Preferably, in this embodiment, the guiding mechanism includes a T-block 19 and a T-slot 20. The T-block 19 is installed on both the left and right ends of the mounting plate 2, and the T-slot 20 is opened on both the left and right ends of the mounting base 3. The T-block 19 and the T-slot 20 are slidably connected. The cooperation between the T-block and the T-slot provides a clear guiding path for the installation of the mounting plate 2, so that the mounting plate 2 can slide accurately along the T-slot during the installation process. The sliding connection between the T-block and the T-slot can limit the mounting plate 2 from both sides after the mounting plate 2 is embedded in the mounting base 3, effectively limiting the swaying and displacement of the mounting plate 2 in the horizontal direction, further enhancing the stability of the level gauge body 1 after installation. Even if the equipment vibrates or is subjected to external impact during operation, the cooperation between the T-block and the T-slot can prevent the mounting plate 2 from shifting, ensuring that the locking mechanism continues to work stably and ensuring that the level gauge can still operate reliably under complex working conditions.

[0027] Preferably, in this embodiment, both the locking block 9 and the locking groove 8 are rectangular designs, with the sides of the rectangles being parallel and perpendicular to each other. When the locking block 9 is embedded in the locking groove 8, all sides fit tightly together, which can restrict the movement of the locking block 9 in the groove in all directions. Compared with other shapes, the rectangular design can effectively resist external forces from different directions, such as horizontal shaking and vertical pulling, which greatly enhances the stability of the level gauge body 1 on the mounting base 3, reduces the risk of the equipment loosening due to external factors such as vibration and collision, and ensures the long-term stable operation of the level gauge.

[0028] Preferably, in this embodiment, two sets of fixing plates 21 are symmetrically installed on the left and right sidewalls of the mounting base 3. Each set of fixing plates 21 is threaded with bolts 22. The standardized design of the fixing plates 21 and bolts 22 makes the radar level gauge mounting base 3 of different batches or models universal and interchangeable during installation.

[0029] Preferably, in this embodiment, a sealing gasket is installed in the mounting groove 4. When the mounting plate 2 is embedded in the mounting groove 4 and fixed by the locking mechanism, the sealing gasket will be squeezed and deformed, filling the tiny gap between the mounting plate 2 and the mounting groove 4. This elastic deformation can effectively block the path of leakage of liquid, gas and other media from the connection, which is especially suitable for scenarios that require strict sealing, such as storage tanks and reaction vessels.

[0030] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
