Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level gauge cleaning technology, specifically to an automatic liquid level gauge cleaning device. Background Technology
[0002] Radar level gauges are widely used in chemical, warehousing and other fields due to their advantages such as non-contact measurement, high accuracy and strong adaptability. In actual working conditions, the probe of a radar level gauge is easily covered by substances such as dust, water vapor, condensate or medium vapor: dust accumulation can form a sound wave reflection barrier, interfering with electromagnetic wave transmission and reception; water vapor condensing into droplets may change the dielectric constant of the probe surface, leading to an expansion of the measurement blind zone or data jumps.
[0003] In the existing technology, automatic cleaning devices rely on high-pressure air blowing to clean the probe head. High-pressure air blowing can only remove some loose particles and is difficult to break the adhesion of sticky substances, so it cannot effectively remove stubborn stains. As a result, a large number of contaminants remain on the surface of the probe head, which seriously affects the detection accuracy. Therefore, we need to propose an automatic cleaning device for level gauges. Utility Model Content

[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 1-4 This utility model provides a technical solution:
[0024] An automatic cleaning device for a liquid level gauge includes a bracket 1, a fixed plate 2 fixedly installed at the bottom of the bracket 1, an electric push rod 3 fixedly installed on the side of the fixed plate 2, a movable plate 8 fixedly installed at the telescopic end of the electric push rod 3, a support plate 10 fixedly installed at the bottom of the movable plate 8, a drive motor 13 fixedly installed at the bottom of the support plate 10, a rotating plate 16 fixedly installed on the output shaft of the drive motor 13, and a cleaning brush strip 17 fixedly installed on the top of the rotating plate 16.
[0025] A mounting base 18 is installed on the top of the rotating plate 16, and a cleaning pad 19 for cleaning is provided on the surface of the mounting base 18.
[0026] The bottom of bracket 1 is equipped with a rinsing mechanism.
[0027] It should be noted that when the rotating plate 16 is driven to rotate by the drive motor 13, the brush strip 17 and the cleaning cotton pad 19 rotate synchronously, so that the brush strip 17 and the cleaning cotton pad 19 can clean the bottom and surface of the probe head 6 at the same time.
[0028] In an optional embodiment: such as Figures 1-4 As shown, it also includes a radar level gauge body 4 fixedly installed on the top of the bracket 1. A probe head 6 is fixedly installed on the bottom of the radar level gauge body 4. The bristles of the brush strip 17 are in contact with the bottom of the probe head 6. The fixing seat 18 is conical. The cleaning cotton pad 19 is in contact with the surface of the probe head 6.
[0029] It should be noted that the bottom of the probe head 6 is cleaned by the brush strip 17, and the surface of the probe head 6 is cleaned by the cleaning cotton pad 19.
[0030] In an optional embodiment: such as Figure 3 As shown, a ring-shaped guide rail 14 is fixedly installed on the top of the support plate 10, and two sets of sliders 15 are symmetrically fixedly installed on the bottom of the rotating plate 16. Both sets of sliders 15 are slidably installed on the ring-shaped guide rail 14.
[0031] It should be noted that when the rotating plate 16 is driven to rotate by the drive motor 13, the rotating plate 16 rotates on the annular guide rail 14 through the slider 15. The slider 15 cooperates with the annular guide rail 14 to support and position the rotating plate 16, so that the rotating plate 16 can stably drive the brush strip 17 and the cleaning cotton pad 19 to rotate.
[0032] In an optional embodiment: such as Figure 2 and Figure 3 As shown, the flushing mechanism includes an annular pipe 5 and a conveying pipe 9. The annular pipe 5 is fixedly installed at the bottom of the bracket 1 and is sleeved on the outside of the probe head 6. The conveying pipe 9 is connected to the annular pipe 5, and multiple sets of nozzles 7 are provided on the annular pipe 5.
[0033] It should be noted that the conveying pipe 9 is connected to an external water supply device, which delivers cleaning water to the conveying pipe 9. After passing through the conveying pipe 9 and the annular pipe 5, the cleaning water is sprayed onto the probe head 6 through the nozzle 7, which can quickly penetrate and soften the sticky dust and stubborn stains on the surface of the probe head.
[0034] In an optional embodiment: such as Figure 2 and Figure 3 As shown, a positioning guide rail 11 is fixedly installed at the bottom of the bracket 1, and the movable plate 8 is slidably installed on the positioning guide rail 11.
[0035] It should be noted that the positioning guide rail 11 serves to support and guide the moving plate 8, enabling the moving plate 8 to move stably.
[0036] In an optional embodiment: such as Figure 2 and Figure 3 As shown, a positioning rod 12 is fixedly connected to the side of the movable plate 8, and the positioning rod 12 is movably inserted into the fixed plate 2.
[0037] It should be noted that when the moving plate 8 is pushed or dragged by the electric push rod 3, the positioning rod 12 moves within the fixed plate 2, which can further improve the stability of the moving plate 8 during movement.
[0038] In an optional embodiment: such as Figure 4 As shown, an annular seat 20 is fixedly connected to the top of the rotating plate 16, and a plug-in post is fixedly connected to the lower end of the fixed seat 18. The plug-in post is inserted into the annular seat 20, and a fixing screw is threaded on the annular seat 20. The threaded end of the fixing screw abuts against the surface of the plug-in post.
[0039] It should be noted that after the cleaning pad 19 becomes dirty, the position of the cleaning pad 19 can be adjusted by loosening the fixing screw and rotating the fixing base 18. The wiping position of the cleaning pad 19 can be adjusted to facilitate the subsequent cleaning of the probe head 6. After the cleaning pad 19 becomes dirty, the fixing base 18 can be disassembled and the cleaning pad 19 can be cleaned.
[0040] The usage process of this utility model is as follows: When it is necessary to clean the radar level gauge, start the electric push rod 3. The telescopic end of the electric push rod 3 pushes the moving plate 8, so that the moving plate 8 drives the support plate 10 to move. When the telescopic end of the electric push rod 3 extends to the maximum stroke, the brush strip 17 contacts the bottom of the probe head 6, and the surface of the cleaning cotton pad 19 contacts the surface of the probe head 6.
[0041] Cleaning water is supplied to the delivery pipe 9 through the water supply equipment. The cleaning water can be transported along the ring pipe 5 and then sprayed onto the probe head 6 through the nozzle 7. The cleaning water sprayed out of the probe head 6 flows down along the probe head 6. The cleaning water can quickly penetrate and soften the sticky dust and stubborn stains on the surface of the probe head. The drive motor 13 is started. The output shaft of the drive motor 13 drives the rotating plate 16 to rotate the brush strip 17. The bottom of the probe head 6 is cleaned when the brush strip 17 rotates.
[0042] Furthermore, when the rotating plate 16 rotates, it drives the fixed base 18 and the cleaning pad 19 to rotate around the probe head 6. As the cleaning pad 19 rotates around the probe head 6, it scrapes and cleans the surface of the probe head 6. In conjunction with the rinsing of the cleaning water, it washes away the dust particles, water vapor condensate, and sticky media residues on the surface and bottom of the probe head 6 after scraping. This effectively avoids the residue of contaminants, improves the cleaning effect of the probe head, ensures the accuracy and stability of the detection data, reduces the risk of equipment failure, and reduces the frequency of manual maintenance. In addition, when the cleaning water rinses the probe head 6, it can also rinse away the cleaned media on the cleaning pad 19.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
