The outer wall of the fixing sleeve 37 is welded to the base frame 20. The base frame 20 is set on the sludge bucket 23. The sludge bucket 23 is used to collect the cleaned oil or impurities. The top of the base frame 20 is connected to a retaining ring 22. The retaining ring 22 is a ring structure and is used to support the handle when the sampling bucket is inverted to prevent the handle from falling directly below the bucket opening and being contaminated.

[0074] Specifically, the base frame 20 includes at least three connecting rods. The connecting rods are bent downward to form an L-shaped structure and are mounted on the waste bin 23. They are positioned by a slot and provide stable support for the fixing sleeve 37. The retaining ring 22 is connected to the top of the base frame 20 by a support rod 21.

The vertical plate of the trolley 42 can fit into the inlet. Guide wheels are provided at the bottom of the horizontal plate of the trolley 42. A positioning rail 43 is provided on the upper surface of the bottom plate of the cleaning box 24 to position the guide wheels. The waste bin 23 is placed on the horizontal plate of the trolley 42. When the trolley 42 enters the cleaning box 24, the waste bin 23 is located below the base frame 20.

[0078] Furthermore, a partition plate 41 is provided on the inner wall of the cleaning box 24. The partition plate 41 is located between the base frame 20 and the waste bin 23. A hollow horn cover 40 is provided at the center of the partition plate 41. The hollow horn cover 40 narrows towards the waste bin 23. The lower diameter of the hollow horn cover 40 is smaller than the diameter of the waste bin 23. The hollow horn cover 40 guides the waste towards the waste bin 23, avoiding splashing of waste oil.

[0079] In this embodiment, the sampling bucket is placed upside down on the vertical rod 1, with the bottom scraper 3 and the wall scraper 6 in close contact with the bucket wall. The sampling bucket is actively pressed down, causing the rotating rod 34 to rotate, which in turn drives the vertical rod 1 to rotate. The wall scraper 6 cleans the inner wall of the sampling bucket, and the bottom scraper 3 cleans the bottom of the sampling bucket. The dirty oil drips into the waste bucket under the guidance of the hollow horn cover 40. The rotating rod 34 is reset by the return spring 35, and the sampling bucket is removed after cleaning is completed.

[0080] Example 4:

[0081] Based on Example 1, combined with Figures 8 to 10 This embodiment provides an automatic oil scraping and cleaning box, and the rotary drive mechanism described in this embodiment is a motor 29.

[0082] This embodiment includes a waste bin 23 and a cleaning box 24. The cleaning box 24 is a hollow shell structure with a cleaning opening 26 at the center of its top for placing a sampling bin. A base frame 20 is welded to the inner wall of the cleaning box 24. The base frame 20 includes a connecting rod and a guide block 27. The upper end of the guide block 27 is conical to facilitate oil collection. One end of the connecting rod is welded to the guide block 27, and the other end is welded to the cleaning box 24. The lower end of the longitudinal rod 1 is rotatably connected to the guide block 27 via a bushing. The lower end passes through the guide block 27, and the lower end of the guide block 27 is connected to the motor 29 by bolts. The output shaft of the motor 29 is connected to the longitudinal rod 1 by a flat key. The longitudinal rod 1 is fitted with a diversion hood 28 above the guide block 27 to prevent the sludge from entering the gap between the longitudinal rod 1 and the guide block 27. The cleaning box 24 places a sludge bucket 23 below the guide block 27 to receive the sludge cleaned from the sampling bucket. The side wall of the cleaning box 24 is movably installed with a side door 25 to facilitate observation and cleaning of the interior and to take out and put in the sludge bucket.

[0083] Specifically, the cleaning port 26 has a matching cover to prevent oil from splashing, and the bottom of the cleaning box 24 is also equipped with casters 33 to facilitate the overall movement of the cleaning box 24.

[0084] In use, motor 29 drives the longitudinal rod 1 to rotate, thereby reducing the tedious manual operation of rotating the sampling bucket for cleaning. During the cleaning process, the diversion hood 28 guides the waste sample to the inclined surface of the guide block 27, avoiding contamination of the gap between the guide block 27 and the longitudinal rod 1. A heating plate 30 can also be fixedly installed on the longitudinal rod 1. The heating plate 30 is embedded inside the longitudinal rod 1 and extends to its bottom. The part of the longitudinal rod 1 below the guide block 27 is fitted with a positive electrode ring 31 and a negative electrode ring 32. The rotation is powered through the positive electrode ring 31 and the negative electrode ring 32. The design of the heating plate 30 allows the longitudinal rod 1 to supply power and heat the heating plate 30 when it rotates. By heating the sludge, the fluidity of the sludge is improved, further enhancing the cleaning effect.

[0091] III. Adjusting the fit:

[0092] During the cleaning process, the sampling bucket is pressed down, the first bonding mechanism makes the bucket wall hanging plate 6 fit with the inner wall of the sampling bucket, and the second bonding mechanism makes the bucket bottom scraper 3 fit with the bottom of the sampling bucket, ensuring the cleaning effect.

[0093] If the fit needs to be adjusted, it can be achieved by adjusting the preload of the fit spring to make the scraper contact the sampling bucket wall more tightly.

[0094] IV. Heating the sludge:

[0095] As the longitudinal rod 1 rotates, the heating plate 30 begins to heat up, heating the sludge. Heating increases the fluidity of the sludge, helping the scraper to more thoroughly clean the oil or impurities in the sampling bucket.

[0096] V. Collect the waste oil:

[0097] The waste bin 23 is placed directly below the guide block 27 at the bottom of the cleaning box 24. During the cleaning process, the scraped oil or impurities will fall into the waste bin 23 along the guide block 27 below the base frame 20.

[0098] After cleaning, turn off motor 29, remove the sampling bucket from the top of the box, and when the sludge in the sludge bucket reaches 2 / 3 full, open the side door 25 of the cleaning box 24, take out the sludge bucket 23, and collect and process the cleaned-off oil or impurities.

[0099] VI. Closure of Work:

[0100] After cleaning, close the side door 25 of the cleaning box 24 and open the cover of the cleaning port 26 to remove the cleaned sampling bucket. Perform necessary inspections and maintenance on the oil skimmer to ensure it is in good working order. Move the cleaning box 24 to the designated location for next use.

[0101] By following the steps above, the cleaning of oil or impurities inside the sampling container can be completed efficiently and conveniently.
