[0002] A radar level gauge is a device used to measure the horizontal height of liquids or solids. It uses radar technology to send and receive signals to determine the distance from the surface of the target object to the sensor, thereby calculating the liquid level.

[0003] In existing technologies, when radar level gauges are installed in leachate environments, microbial films quickly adhere to them, causing signal attenuation and frequent false water level readings. This requires regular manual disassembly, cleaning, and maintenance, which is inconvenient. Furthermore, the radar level gauge is not easy to remove quickly during subsequent maintenance. Therefore, it is necessary to design a corrosion-resistant and self-cleaning radar level gauge protection device to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a corrosion-resistant and self-cleaning radar level gauge protection device, comprising: Assembly block 1 is threadedly connected to radar level gauge 2. Assembly block 1 and radar level gauge 2 are equipped with disassembly and assembly protection mechanisms. It should be noted that the bottom probe of radar level gauge 2 can be high-pressure flushed periodically to wash away the microbial film attached to the bottom probe of radar level gauge 2. This protects radar level gauge 2 and ensures the accuracy of radar level gauge 2 during use. No manual cleaning is required. Moreover, it is convenient and quick to disassemble when maintenance is required in the future. The disassembly and assembly protection mechanism includes a high-pressure water pipe 3, a hollow ring 4, a high-pressure nozzle 5, a support frame 6, a moving frame 7, a servo motor 8, a welding plate 9, and a splicing block 10; The high-pressure water pipe 3 is fixedly installed on the assembly block 1. The high-pressure water pipe 3 is fixedly connected to the hollow ring 4. The high-pressure nozzle 5 is fixedly installed on the inner side of the hollow ring 4. It should be noted that the high-pressure nozzle 5 is tilted and faces the bottom probe of the radar level gauge 2, and does not block the bottom probe of the radar level gauge 2, so as not to affect the normal operation of the radar level gauge 2. The high-pressure water pipe 3 is connected to the external high-pressure pump body for water supply treatment. The support frame 6 is fixedly installed on the top of the assembly block 1. The movable frame 7 is fixedly connected to the servo motor 8. The movable frame 7 is slidably installed on the support frame 6. The output end of the servo motor 8 is fixedly connected to the radar level gauge 2. The splicing block 10 is slidably installed on the assembly block 1. The splicing block 10 is clamped to the welding plate 9.

[0027] With the above structure, an assembly hole is pre-drilled on the top of the equipment to be installed for snap-fitting with the assembly block 1. A welding plate 9 is pre-welded to the top of the equipment. After the assembly block 1 is snapped into the assembly hole, the splicing block 10 is pushed, causing it to snap into the welding plate 9. Then, the servo motor 8 is activated, causing the radar level gauge 2 to rotate 45 degrees. At this time, the moving frame 7 moves down synchronously to the position shown in the diagram to block and limit the splicing block 10. Later, when it is necessary to flush and protect the bottom probe of the radar level gauge 2, the external high-pressure pump is turned on, and the servo motor 8 is activated, causing the radar level gauge 2 to continue rotating slowly. At 45 degrees, the radar level gauge 2 rotates and moves downward. Then, the output of the servo motor 8 drives the radar level gauge 2 to rotate slowly in the opposite direction by 45 degrees back to its original position. This allows the radar level gauge 2 to reverse and move upward. This process is repeated multiple times, so that the clean water sprayed from the high-pressure nozzle 5 can evenly rinse the bottom probe of the radar level gauge 2, washing away the microbial film attached to the bottom probe of the radar level gauge 2. This protects the radar level gauge 2 and ensures its accuracy during use. No manual cleaning is required. Moreover, when maintenance is needed later, the servo motor 8 can be started to reverse its output by 45 degrees, making it easy to quickly remove.

[0028] It should be added that the servo motor 8 is controlled by an external PLC controller. The external PLC controller can precisely control the output of the servo motor 8 to rotate 45 degrees in both directions. The program is set in advance on the external PLC controller. When the set time is reached, the servo motor 8 can automatically start and precisely control the radar level gauge 2 to rotate 45 degrees in the forward direction and then 45 degrees in the reverse direction, which can be achieved with precision.

[0029] Specifically, the high-pressure water pipe 3 is connected to the interior of the hollow ring 4, and the high-pressure nozzle 5 is connected to the interior of the hollow ring 4.

[0030] The above structure facilitates the flow of clean water.

[0031] Specifically, the radar level gauge 2 has an external thread on its outer side, and the assembly block 1 has a screw hole on its top. The external thread is threaded to the screw hole. It should be noted that the radar level gauge 2 can also move vertically when it rotates.

[0032] Specifically, the support frame 6 has a movable hole at the top, the movable frame 7 is vertically slidably installed in the movable hole, the movable frame 7 is slidably sleeved on the outside of the high pressure water pipe 3, the support frame 6 has a side hole 12 on the side, and the movable frame 7 passes through the side hole 12. It should be noted that this allows the movable frame 7 to move vertically.

[0033] Specifically, the top of the assembly block 1 has a top groove 13, the splicing block 10 is slidably installed in the top groove 13, the side of the moving frame 7 abuts against the splicing block 10, the side of the welding plate 9 has a splicing groove 11, the splicing block 10 is engaged with the splicing groove 11, it should be noted that this is to facilitate the limiting treatment of the splicing block 10.

[0034] Specifically, a sealing gasket is embedded and fixedly connected to the outer side of assembly block 1, and a sealing gasket is embedded and fixedly connected to the bottom of assembly block 1. It should be noted that the function of sealing gasket 1 is to ensure the sealing between assembly block 1 and the assembly hole, and the function of sealing gasket 2 is to ensure the sealing between radar level gauge 2 and the screw hole. The sealing gasket is made of polytetrafluoroethylene, which has good wear resistance and corrosion resistance. Assembly block 1, radar level gauge 2 housing, high-pressure water pipe 3, hollow ring 4, and high-pressure nozzle 5 are integrally injection molded with PVDF, and the surface is then coated with PTFE nano-coating, thus having good corrosion resistance.

[0035] Working principle: S1: The top of the equipment to be installed has a pre-set assembly hole and welding plate 9. Align the bottom of the assembly block 1 with the assembly hole and insert it vertically. Push the splicing block 10 in the top groove 13 of the top of the assembly block 1 so that it slides laterally and is inserted into the splicing groove 11 of the welding plate 9. The rigid engagement between the splicing block 10 and the splicing groove 11 restricts the lateral displacement of the assembly block 1, completing the initial fixation. Start the servo motor 8. The output end of the servo motor 8 drives the radar level gauge 2 to rotate 45° clockwise. During the rotation, the radar level gauge 2 moves slowly downward along the screw hole axis. At the same time, the servo motor 8 drives the moving frame 7 to move vertically downward along the moving hole of the support frame 6 until the side of the moving frame 7 completely covers the top of the splicing block 10. The blocking and limiting of the moving frame 7 prevents the splicing block 10 from loosening and falling out, and finally achieves the double fixation of the assembly block 1 and the equipment. S2: According to the preset cycle, the external high-pressure pump starts, and high-pressure clean water is delivered to the hollow ring 4 through the high-pressure water pipe 3; at the same time, the servo motor 8 starts, and the output end drives the radar level gauge 2 to continue to rotate clockwise by 45°. The radar level gauge 2 moves further down along the screw hole, and the probe is fully exposed within the coverage area of ​​the high-pressure nozzle 5 on the inner side of the hollow ring 4. The high-pressure clean water in the hollow ring 4 is sprayed out through the high-pressure nozzle 5 to form a high-pressure water flow; the servo motor 8 drives the radar level gauge 2 to slowly rotate counterclockwise by 45° to return to its original position. During the rotation, the radar level gauge 2 moves upward synchronously, and the probe comes into 360° all-round contact with the high-pressure water flow to thoroughly wash away the microbial film and leachate residues attached to the surface; this is repeated 2-3 times to ensure that the probe is thoroughly cleaned. After cleaning, the servo motor 8 drives the radar level gauge 2 back to the initial working position, the moving frame 7 maintains the obstruction limit on the splicing block 10, the high-pressure pump is turned off, and the device resumes the liquid level monitoring state; the whole process does not require manual intervention; S3: When the radar level gauge needs to be inspected, it can be quickly disassembled by reversing the operation. No complicated tools are required. Start the servo motor 8, and the output end drives the radar level gauge 2 to rotate counterclockwise by 45°. The radar level gauge 2 slowly moves upward along the screw hole axis, while driving the moving frame 7 to move upward along the moving hole of the support frame 6 until the moving frame 7 is completely separated from the splicing block 10, releasing the obstruction and limitation on the splicing block 10. Push the splicing block 10 in the opposite direction so that it slides out of the splicing groove 11 of the welding plate 9, releasing the lateral limitation of the assembly block 1. Pull the assembly block 1 upward so that it is taken out from the equipment assembly hole. At this time, the radar level gauge 2 is still threadedly connected to the assembly block 1 and is disassembled together with the assembly block 1.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
