[0024] Each cleaning block 204 is provided with a plurality of scrapers on one side close to the inner wall of the oil tank barrel 555 .

[0025] The cleaning blocks 204 on the left and right sides of the cleaning rod 106 are arranged alternately.

[0026] The working principle of the above embodiment is as follows: First, Figure 1 is the viewing angle reference, where the side where the mobile frame 1 is marked is the left side; In the prior art, when cleaning the oil tank barrel 555, because the movable frame 1 and the rotating frame 3 are frame structures with limited load-bearing capacity, and multiple oil tank barrels 555 are loaded on the rotating frame 3 for simultaneous cleaning, in order to prevent the oil tank barrel 555 from being too heavy and affecting the operation of the equipment, the worker only injects an appropriate amount of cleaning solution into the oil tank barrel 555. At this time, the cleaning solution cannot completely cover the inner wall of the oil tank barrel 555. Figure 1 and Figure 2As shown: the electric roller 7 is controlled to rotate counterclockwise, thereby driving the oil tank barrel 555 to rotate counterclockwise, and at the same time, the rotating frame 3 is driven to swing back and forth through the first motor 2, thereby shaking the cleaning solution in the oil tank barrel 555, and driving the oil tank barrel 555 to rotate, so that the cleaning solution in the oil tank barrel 555 can fully wet and soak the inner wall of the oil tank barrel 555, thereby improving the softening effect of the cleaning solution on the oil stains on the inner wall of the oil tank barrel 555 and improving the cleaning effect. However, in this process, the water on the inner wall of the oil tank barrel 555 cannot be replaced. As the cleaning proceeds, the water in the oil tank barrel 555 will become dirtier and dirtier, causing the subsequent solution to lose its cleaning effect; and the sewage in the oil tank barrel 555 cannot be discharged in time; at the same time, during the shaking process, the sewage is easily thrown out of the oil tank barrel 555 and leaked to the ground, causing the sewage to carry oil stains to pollute the soil, which is obviously contrary to strict environmental protection requirements.

[0027] In order to solve the above problems, the present invention proposes the following method. It should be noted that in the prior art, there are upper covers of oil tank barrels 555 that can be directly disassembled, and there are also upper covers of oil tank barrels 555 that are not integrated. Workers can cut or directly remove the upper covers of the oil tank barrels 555 that need to be cleaned according to needs, and then the workers remove the fixing plate 5, and then the upper part of the oil tank barrel 555 is pressed forward against the cover plate 101 and placed in the rotating frame 3; after the oil tank barrel 555 is placed, the workers reinstall the fixing plate 5. Figure 2 and Figure 3 As shown, the lower part of the oil tank barrel 555 is supported and limited by two electric rollers 7, the rear side of the oil tank barrel 555 is limited by the fixed plate 5, and the rotating plate 102 contacts the front side of the oil tank barrel 555 to seal the front side of the oil tank barrel 555, thereby preventing the oil tank barrel 555 from shifting significantly during the cleaning process, causing sewage to be thrown out and leaked; then the worker can control the equipment through the control box 4 to perform the cleaning operation described in the previous paragraph on the oil tank barrel 555; Furthermore, when there are a lot of oil stains and impurities in the oil tank barrel 555, it is difficult to clean the oil stains and impurities in the oil tank barrel 555 by only driving the rotating frame 3 to swing back and forth through the first motor 2, and then shaking the cleaning solution in the oil tank barrel 555 to clean the inner wall of the oil tank barrel 555, and the oil stains and impurities cannot be discharged from the oil tank barrel 555 in time. Figure 3-Figure 5As shown: in the process of placing the oil tank barrel 555 into the rotating frame 3, the fixing rod 105 and the cleaning rod 106 will also enter the oil tank barrel 555, and the bristles on the cleaning rod 106 will contact the inner wall of the oil tank barrel 555; then the worker connects the water inlet pipe 8 with the external water pipe. It should be noted that the worker can prepare alkaline cleaning solution in advance; the solution is pumped into the water inlet pipe 8 through the external water pipe, and then the oil stains are softened by the cleaning solution to improve the cleaning effect; then the worker controls the first motor 2 through the control box 4 to drive the rotating frame 3 to rotate, so that the oil tank barrel 555 is in a state of tilting from the upper rear side to the lower front side; then the worker places a collecting bucket on the lower side of the drainage board 209, and then adds cleaning solution to the water inlet pipe 8 through the external water pipe. , the cleaning solution will enter the water inlet tank 10501 through the water inlet channel 10701 in the rotary joint 107, and then enter the corresponding sprayer 201 through the first connecting pipe 202, and the inner wall of the oil tank barrel 555 will be rinsed more evenly by the sprayer 201, and the worker can increase the water injection pressure to improve the flushing effect of the cleaning solution on the larger oil stains and impurities on the inner wall of the oil tank barrel 555; at the same time, the worker can drive the fixed rod 105, the cleaning rod 106 and the sprayer 201 to rotate through the second motor 104, and then the inner wall of the oil tank barrel 555 is fully rinsed to improve the flushing effect, and at the same time, the larger oil stains and impurities on the inner wall of the oil tank barrel 555 are scraped off by the cleaning rod 106 and the cleaning block 204, and A scraper is provided on the cleaning block 204. During the rotation of the cleaning block 204, the scraper can be used to scrape the oil and dirt caked on the inner wall of the oil tank barrel 555, so that the cleaning block 204 and the cleaning rod 106 can clean the inner wall of the oil tank barrel 555. At this time, the worker can control the electric rotating plate 208 to rotate and open through the control box 4, so that the larger oil and impurities cleaned from the oil tank barrel 555 will be directly discharged into the collection barrel through the drain port 10201 and the drain plate 209, thereby forming a flowing cleaning solution in the oil tank barrel 555, and quickly discharging the oil and impurities in the oil tank barrel 555, thereby improving the cleaning effect. When the larger oil and impurities in the oil tank barrel 555 are cleared, the worker stops injecting the solution into the oil tank barrel 555. Then, the medicine in the oil tank barrel 555 is emptied, and then the electric rotating plate 208 is controlled by the control box 4 to rotate and close, and then new cleaning medicine is added to the oil tank barrel 555 through the water inlet pipe 8. It should be noted here that during the cleaning process, the oil tank barrel 555 is in a stationary state. At this time, the pressure relief valve 110 is in an open state, and the gas in the oil tank barrel 555 can be discharged through the pressure relief valve 110 to avoid the internal expansion of the sealed oil tank barrel 555 during the flushing process, causing the oil tank barrel 555 to be expanded and cracked. Then, the worker controls the first motor 2 through the control box 4 to drive the rotating frame 3 to swing back and forth, and at the same time drives the oil tank barrel 555 to rotate, thereby shaking the cleaning medicine in the oil tank barrel 555 to remove the residual impurities in the oil tank barrel 555; Furthermore, if Figure 3-Figure 5As shown: Based on the view from the front to the back, the second motor 104 drives the fixing rod 105, the cleaning rod 106 and the cleaning block 204 to rotate clockwise. When cleaning the inner wall of the oil tank barrel 555, the electric roller 7 is controlled to rotate counterclockwise, thereby driving the oil tank barrel 555 to rotate counterclockwise. At this time, the rotating plate 102 and the limiting plate 6 rotate clockwise following the oil tank barrel 555, thereby realizing the reverse rotation of the oil tank barrel 555 during the cleaning process, thereby increasing the friction between the cleaning rod 106 and the cleaning block 204 and the inner wall of the oil tank barrel 555, thereby improving the cleaning effect; Furthermore, in order to facilitate the placement of the oil tank barrel 555 on the rotating frame 3, the front-to-back length of the rotating frame 3 must be greater than the front-to-back length of the oil tank barrel 555. Therefore, after the oil tank barrel 555 is placed on the rotating frame 3, there will be a certain gap between the oil tank barrel 555 and the front and rear baffles of the rotating frame 3. At this time, gas is injected into the telescopic airbag 206 through the air pump 205, so that the telescopic airbag 206 expands and extends backward, thereby squeezing the cover plate 101 and the rotating plate 102 backward, and then squeezing the oil tank barrel 555 backward through the rotating plate 102, so that the rear side of the oil tank barrel 555 contacts the limit plate 6, and then the front and rear positions of the oil tank barrel 555 are clamped by the limit plate 6 and the rotating plate 102, ensuring the sealing of the cover plate 101 and the rotating plate 102 to the oil tank barrel 555; and in order to facilitate the fixing rod 105 and the cleaning rod 106 to enter the interior of the oil tank barrel 555, as shown in FIG. Figure 4-Figure 6 As shown: in the initial state, the cleaning rod 106 is in contact with the fixed rod 105, and the bristles on the cleaning rod do not contact the inner wall at this time, so the cleaning rod can enter the oil tank barrel 555 more easily; after the oil tank barrel 555 is placed in the rotating frame 3, while gas is injected into the telescopic airbag 206 through the air pump 205, the gas will also enter the air inlet groove 10502 through the second connecting pipe 207 and the air inlet channel 10702 in the rotating joint 107, thereby squeezing the sliding rod 108. At this time, the spring 109 is compressed and contracted, and the cleaning rod 106 approaches the inner wall of the oil tank barrel 555, and then the bristles on the cleaning rod 106 will contact the inner wall of the oil tank barrel 555, and then the cleaning operation can be carried out smoothly.

[0028] Example 2 On the basis of Example 1, Figure 2-Figure 5 As shown, it also includes a cleaning roller 9 and a magnet 203; each cleaning rod 106 is fixedly connected to a magnet 203 on one side close to the inner wall of the oil tank barrel 555; three cleaning rollers 9 are fixedly connected to the rotating frame 3, and each cleaning roller 9 is located directly below the corresponding oil tank barrel 555; a flow valve is provided in each second connecting pipe 207; it should be noted that the reset force of the spring 109 is greater than the magnetic attraction force of the magnet 203.

[0029] The working principle of the above embodiment is as follows: Furthermore, in the prior art, when the oil tank barrel 555 is driven by the electric roller 7 to rotate to clean the outer side of the oil tank barrel 555, since the oil tank barrel 555 is in a passive rotation state, the cleaning effect of the electric roller 7 and the outer side of the oil tank barrel 555 is poor. Therefore, after the inner wall of the oil tank barrel 555 is cleaned, Figure 4 and Figure 5 As shown: when gas is injected into the telescopic airbag 206 through the air pump 205 so that the bristles on the cleaning rod 106 contact the inner wall of the oil tank barrel 555, the flow valve in the second connecting pipe 207 controls the gas entering the air inlet groove 10502, thereby controlling the squeezing force of the gas on the sliding rod 108 and the spring 109, thereby controlling the moving distance of the sliding rod 108 and the cleaning rod 106; when it is necessary to clean the outer surface of the oil tank barrel 555; the air pump 205 continues to inject gas into the air inlet groove 10502, and then the sliding rod 108 and the cleaning rod 106 will continue to approach the inner wall of the oil tank barrel 555, thereby making the magnet 203 contact the inner wall of the oil tank barrel 555, thereby magnetically attracting the inner wall of the oil tank barrel 555, and then controlling the air pump 205 to stop injecting gas into the air inlet groove 10502, and then as shown in Figure 3-Figure 5 As shown, based on the view from front to back, the fixing rod 105 is driven by the second motor 104 to rotate clockwise, and then the oil tank barrel 555 is driven by the magnet 203 to rotate clockwise. At this time, the electric cleaning roller 9 is started to rotate counterclockwise, and then the friction between the electric cleaning roller 9 and the outer surface of the oil tank barrel 555 is increased by the reverse rotation, thereby improving the cleaning effect on the outer surface of the oil tank barrel 555; after the outer surface of the oil tank barrel 555 is cleaned, the gas in the air inlet groove 10502 is extracted by the air pump 205, and then the spring 109 will slide the rod 108, the cleaning rod 106 and the magnet 203 toward the inner wall of the original oil tank barrel 555, thereby releasing the magnetic attraction effect of the magnet 203 on the inner wall of the oil tank barrel 555. It should be noted here that the reset force of the spring 109 is greater than the magnetic attraction force of the magnet 203 on the inner wall of the oil tank barrel 555.
