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.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The radar liquid level measuring device shown in this application includes a controller and a power supply. The controller controls electrical components (such as motors and telescopic hydraulic cylinders), and the power supply provides power; these are existing technologies and will not be described in detail here. It includes a storage tank 1 for storing the liquid to be measured, providing a liquid-bearing foundation for the entire device and ensuring the stability of the object being measured. A shielding frame 3 is fixedly connected to the top of the storage tank 1 to prevent dust, debris, etc., from entering the storage tank 1 or adhering to key components on the top, reducing interference from impurities on the device's operation. A cleaning component is installed on the top of the storage tank 1 to clean the top of the storage tank 1 and related components, preventing impurity accumulation from affecting the accuracy of radar liquid level measurement. The cleaning component includes a sliding frame 4 mounted on the top of the storage tank 1 and adapted to the shielding frame 3, providing mounting support for other components of the cleaning component and sliding along the shielding frame 3 to achieve cleaning within a certain range. The sliding frame 4 is covered by a support plate 5 fixedly connected to its outer side. This support plate 5 is used to fix the mounting base 6 and the air pump 8, improving the stability of the component installation and ensuring reliable component positioning during cleaning. The mounting base 6 is fixedly connected to the outer side of the support plate 5, which can be used to install the core component of the radar liquid level detection, allowing the detection component and the cleaning component to be arranged in a coordinated manner, thus optimizing the structural layout of the device. The air pump 8 is fixedly connected to the outer side of the support plate 5, providing a high-pressure gas source for the air blowing pipe 9. This is the power device for realizing the cleaning function. A pair of air blowing pipes 9 are fixedly connected to the output end of the air pump 8, used to guide the high-pressure gas provided by the air pump 8 to the designated cleaning area, realizing directional air blowing cleaning. An impurity collection component is provided on the outer side of the sliding frame 4 for collecting impurities. The impurities blown off during the process are prevented from secondary contamination or scattering. The impurity collection component includes a toothed ring 15 fixedly connected to the outside of the sliding frame 4, which meshes with a gear 11 to transmit power, driving the sliding frame 4 to rotate, and simultaneously forming an auxiliary enclosure structure for impurity collection. A pair of collection frames 13 are detachably connected to the outside of the storage tank 1 to receive and store the blown-off impurities. The detachable design facilitates subsequent impurity cleaning and collection frame maintenance. A connecting block 14 is fixedly connected to the outside of the collection frame 13 to achieve a detachable connection between the collection frame 13 and the storage tank 1, improving the ease of installation and removal of the collection frame 13. A gap is provided between the toothed ring 15 and the storage tank 1 to provide a channel for impurities to fall into the collection frame 13, ensuring that the blown-off impurities are collected safely. The fallen impurities can smoothly enter the collection area. One of the air blowing pipes 9 is directed towards the top of the liquid storage tank 1 to blow and clean the impurities accumulated at the top of the liquid storage tank 1, so as to prevent the impurities from affecting the sliding frame 4. The other air blowing pipe 9 is directed towards the gear ring 15 to clean the impurities attached to the surface of the gear ring 15, so as to prevent the impurities from jamming the meshing transmission between the gear 11 and the gear ring 15. A motor 10 is fixedly connected to the outside of the liquid storage tank 1, which provides power for the rotation of the gear 11 and is the power source for the rotation of the sliding frame 4. The output end of the motor 10 is fixedly connected to the gear 11 that meshes with the gear ring 15, which transmits the power of the motor 10 to the gear ring 15. Through meshing transmission, the gear ring 15 and the sliding frame 4 are driven to rotate, realizing the circumferential cleaning motion of the cleaning component.

[0019] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a protective cover 2 be detachably connected to the top of the storage tank 1. The protective cover 2 is adapted to the motor 10, gear 11, and gear ring 15, and its function is to isolate external dust and debris, prevent transmission components from being contaminated or accidentally touched, ensure the transmission stability of the motor 10, gear 11, and gear ring 15, and extend their service life. A liquid level radar sensor body 7 is provided on the outside of the mounting base 6, and its function is to detect the liquid level height in the storage tank 1 in real time, output accurate liquid level data, and provide data support for liquid replenishment or discharge. The collection frame 13 is located directly below the gear ring 15, and its function is to collect lubricating grease, debris, and other impurities that may fall off during the transmission of the gear ring 15, preventing impurities from falling into the storage tank 1 and contaminating the liquid. A load-bearing ring 12 is fixedly connected to the outside of the storage tank 1. The load-bearing ring 12 is adapted to the collection frame 13, and its function is to provide stable support for the collection frame 13, ensure the accuracy of the installation position of the collection frame 13, and ensure its effectiveness in collecting impurities.

[0020] The working principle of this utility model is as follows: The control motor 10 drives the gear 11 to rotate, which in turn drives the sliding frame 4, support plate 5, mounting base 6, and liquid level radar sensor body 7 to deflect through the gear ring 15. This facilitates monitoring of the liquid level at different positions to improve monitoring accuracy. The control air pump 8 blows the movement track through one of the air pipes 9, and impurities and debris will leak through the gap between the top of the liquid storage tank 1 and the gear ring 15. The other air pipe 9 cleans the surface of the gear ring 15. The collection frame 13 is set to collect impurities and debris, reducing the obstruction and impact of impurities and debris on the movement track on the sliding frame 4. The protective cover 2 and the collection frame 13 can be removed to facilitate the cleaning of impurities and debris.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
