Technical Field
[0001] This utility model relates to the field of liquid level radar technology, specifically a retractable multi-point radar liquid level measuring instrument. Background Technology
[0002] In fields such as industrial production, energy storage, municipal water supply, and chemical reactions, "liquid level measurement" is one of the core links to achieve process monitoring, safety early warning, resource management, and automated control. The scalable multi-point radar liquid level meter is a new type of measuring equipment that has gradually developed under the drive of this technical pain point and market demand. However, existing radar level gauges still have some problems in use: First, existing radar level gauges are generally installed at a fixed height. This fixed height limits the measurement range of the level gauge, making it impossible to achieve multi-point measurement and thus reducing the practicality of the level gauge. Secondly, existing radar level gauges are generally fixed installations. Fixed installations result in high disassembly costs and cumbersome disassembly during later maintenance, directly affecting the continuity of level measurement and overall efficiency. Utility Model Content
[0003] To address the limitations of existing radar level gauges in terms of fixed height measurement range and inconvenient installation and maintenance, the purpose of this invention is to provide a retractable multi-point radar level gauge.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: a telescopic multi-point radar level gauge, including a bracket, a telescopic component at the top of the bracket, a first connecting block on one side of the telescopic component, a second connecting block on one side of the first connecting block, a quick-connect component between the first connecting block and the second connecting block, a mounting ring fixedly connected to one side of the second connecting block, a level gauge body fixedly installed on the inner wall of the mounting ring, the telescopic component including a protective shell, the protective shell fixedly installed on the upper surface of the bracket, a stepper motor fixedly installed on the upper surface of the protective shell, and the output end of the stepper motor penetrating the upper surface of the protective shell and fixedly connected to a lead screw, the bottom end of the lead screw being rotatably connected to the inner wall of the protective shell, a slider threaded on the outer surface of the lead screw, and the first connecting block fixedly installed on one side of the slider.
[0005] Preferably, the quick-connect assembly includes a docking rod, which is movably engaged between a first connecting block and a second connecting block. Limiting pins are movably inserted between the upper surfaces of the first and second connecting blocks and the docking rod, and bolts are threadedly connected between the limiting pins and the docking rod.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a telescopic component, the detection height and position of the radar level gauge can be flexibly adjusted, enabling the radar level gauge to achieve multi-point measurement at different heights, thereby effectively improving the practicality of the level gauge. 2. This application uses quick-connect components and movable connections to assemble the level gauge, making the overall structure of the level gauge more convenient for later maintenance, disassembly and installation, reducing maintenance costs, and effectively ensuring the continuity of level monitoring and the overall efficiency of the equipment.

Detailed Implementation
[0012] 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.
[0013] Example: Figure 1-3As shown, this utility model provides a telescopic multi-point radar level gauge, including a bracket 1, which provides stable support for the overall structure. The top of the bracket 1 is provided with a telescopic component 2, which can adjust the height of the level gauge body 6 to achieve multi-point measurement. A first connecting block 4 is provided on one side of the telescopic component 2, and a second connecting block 5 is provided on one side of the first connecting block 4. A quick-connect component 3 is provided between the first connecting block 4 and the second connecting block 5. The quick-connect component 3 enables quick assembly and disassembly of the level gauge body 6 through the cooperation of the first connecting block 4 and the second connecting block 5. An installation ring 7 is fixedly connected to one side of the second connecting block 5. The level gauge body 6 is fixedly installed on the inner wall of the installation ring 7. The installation ring 7 ensures that the level gauge body 6 is installed firmly. The coordinated work of all components improves the practicality and ease of maintenance of the equipment.
[0014] The telescopic component 2 includes a protective shell 25, which is fixedly mounted on the upper surface of the bracket 1. A stepper motor 22 is fixedly mounted on the upper surface of the protective shell 25, providing precise power output. A protective cover 21 for use with the stepper motor 22 is fixedly mounted on the upper surface of the protective shell 25. The stepper motor 22 is fixedly mounted inside the protective cover 21, which protects the stepper motor 22. The output end of the stepper motor 22 passes through the upper surface of the protective shell 25 and is fixedly connected to a lead screw 23, which drives the lead screw 23 to rotate. The bottom end of the lead screw 23 is rotatably connected to the inner wall of the protective shell 25 to ensure the stability of the lead screw 23 rotation. The outer surface of the lead screw 23 is threaded with a slider 24. The threaded engagement between the lead screw 23 and the slider 24 realizes linear transmission. The outer surface of the slider 24 is slidably connected to the inner wall of the protective shell 25, and the sliding connection between the slider 24 and the protective shell 25 ensures the stability of the lifting process. The first connecting block 4 is fixedly installed on one side of the slider 24. The movement of the slider 24 drives the first connecting block 4 and the level gauge body 6 to achieve precise height adjustment, meeting the needs of multi-point measurement.
[0015] The quick-connect assembly 3 includes a connecting rod 36, which is movably engaged between the first connecting block 4 and the second connecting block 5. The connecting rod 36 enables the initial connection between the first connecting block 4 and the second connecting block 5. A limiting strip 34 is symmetrically fixedly connected to the upper surface of the connecting rod 36. The limiting strip 34 is movably inserted into the first connecting block 4 and the second connecting block 5. The limiting strip 34 has a T-shaped cross-section, which enhances the shear resistance of the connection and prevents lateral misalignment between the two.
[0016] Limiting pin plates 33 are movably inserted between the upper surfaces of the first connecting block 4 and the second connecting block 5 and the docking rod 36. The limiting pin plates 33 are magnetic pins, and the limiting pin plates 33 and the docking rod 36 are magnetically inserted. The magnetic limiting pin plates 33 can quickly achieve axial limiting. The limiting pin plates 33 and the docking rod 36 are threadedly connected by bolts 31. The bolts 31 further improve the connection tightness, and the double fixing ensures the stability of the installation.
[0017] The upper surface of the limiting pin plate 33 is provided with a magnetic groove 35. The inner wall of the magnetic groove 35 is magnetically attached to a rain cover 32 for use with the bolt 31. The bolt 31 is located inside the rain cover 32. The rain cover 32 is attracted to the limiting pin plate 33 through the magnetic groove 35, which can effectively protect the bolt 31 from rainwater corrosion, extend the service life of the component, and make the disassembly and assembly of the level gauge more convenient and reduce maintenance costs.
[0018] Working principle: First, the entire measuring device is fixed at the designated installation position of the liquid level to be measured by bracket 1 to ensure the overall stability of the device and provide basic support for subsequent measurement work. Next, the liquid level gauge body 6 is assembled. The inner wall of the mounting ring 7, which is fixedly connected to one side of the second connecting block 5, is fixedly installed to the liquid level gauge body 6, so that the liquid level gauge body 6 can be adjusted in position by cooperating with subsequent components through the second connecting block 5. Then, the quick-connect assembly 3 is used to connect the first connecting block 4 and the second connecting block 5, and the docking rod 36 is movably snapped between the first connecting block 4 and the second connecting block 5. At the same time, the T-shaped limiting strip 34, which is symmetrically fixed on the upper surface of the docking rod 36, is movably inserted into the first connecting block 4 and the second connecting block 5. The limiting strip 34 restricts the relative displacement of the first connecting block 4 and the second connecting block 5 in the horizontal direction, thus initially completing the positioning of the two. Subsequently, the limiting pin plate 33, which acts as a magnetic attraction pin, is movably inserted between the upper surfaces of the first connecting block 4 and the second connecting block 5 and the docking rod 36. By utilizing the magnetic attraction of the limiting pin plate 33 and the docking rod 36, the connection stability of the first connecting block 4, the second connecting block 5 and the docking rod 36 is further enhanced, preventing vertical separation. Finally, bolt 31 is threaded between limit pin plate 33 and connecting rod 36, and rain cover 32 used with bolt 31 is magnetically snapped into the inner wall of magnetic groove 35 opened on the upper surface of limit pin plate 33, so that bolt 31 is inside rain cover 32, avoiding corrosion of bolt 31 by rainwater and other external factors, and ensuring long-term stable connection of quick-connect assembly 3. When the height of the liquid level gauge body 6 needs to be adjusted according to the liquid level measurement requirements, the stepper motor 22 in the telescopic assembly 2 is started. The output end of the stepper motor 22 drives the lead screw 23 to rotate, and the rotation of the lead screw 23 drives the slider 24 to slide along the inner wall of the protective shell 25.
[0019] The slider 24 will drive the first connecting block 4 to rise and fall synchronously, thereby realizing the height adjustment of the liquid level gauge body 6 until the liquid level gauge body 6 reaches a suitable multi-point position for measurement. Once the level gauge body 6 is adjusted to the target measurement position, the level gauge body 6 activates the radar measurement function and emits radar waves to the liquid level in the container. When radar waves hit the liquid surface, they are reflected, and the reflected radar waves are received by the level gauge body 6. Based on the time difference between transmitting and receiving the reflected radar waves, and combined with the speed of radar wave propagation in air, the level gauge body 6 calculates the distance from the level gauge body 6 to the liquid surface, and then calculates the liquid level height in the container, completing multi-point liquid level measurement. The measurement data is then transmitted to the relevant control system or display device to realize the feedback of liquid level information. When maintenance or replacement of the level gauge body 6 is required, first remove the rain cover 32 on the inner wall of the magnetic suction groove 35, then unscrew the bolt 31 between the limit pin plate 33 and the connecting rod 36, and then pull out the limit pin plate 33 that serves as the magnetic suction pin.
[0020] Finally, remove the docking rod 36 from between the first connecting block 4 and the second connecting block 5 to separate the first connecting block 4 and the second connecting block 5, and then perform maintenance or replacement operations on the level gauge body 6.
[0021] After maintenance and replacement are completed, simply reassemble the equipment following the reverse steps to restore its usability.
[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
