[0033] A plurality of scraping blades are arranged on one side of each cleaning block 204 close to the inner wall of the oil tank barrel 555.

[0034] The cleaning blocks 204 on the left and right sides of the cleaning rod 106 are arranged staggeredly.

[0035] The working principle of the above embodiment is as follows:

[0036] First, taking Figure 1 as the perspective reference, the side where the label of the moving frame 1 is located is the left side;

[0037] In the prior art, when cleaning the oil tank barrel 555, since the moving frame 1 and the rotating frame 3 are of a frame structure and have limited load-bearing capacity, and multiple oil tank barrels 555 will be loaded on the rotating frame 3 for cleaning at the same time, in order to prevent the oil tank barrel 555 from being too heavy and affecting the operation of the equipment, workers will only inject an appropriate amount of cleaning liquid into the oil tank barrel 555. At this time, the cleaning liquid cannot completely cover the inner wall of the oil tank barrel 555. Therefore, as shown in Figure 1 and Figure 2 : Control the electric roller 7 to rotate counterclockwise, thereby driving the oil tank barrel 555 to rotate counterclockwise. At the same time, drive the rotating frame 3 to swing back and forth through the first motor 2, thereby shaking the cleaning liquid in the oil tank barrel 555 and driving the oil tank barrel 555 to rotate. As a result, the cleaning liquid in the oil tank barrel 555 can fully wet and soak the inner wall of the oil tank barrel 555, improving the softening effect of the cleaning liquid on the oil stain on the inner wall of the oil tank barrel 555 and improving the cleaning effect. However, during this process, the water on the inner wall of the oil tank barrel 555 cannot be replaced. As the cleaning progresses, the water in the oil tank barrel 555 will become dirtier and dirtier, resulting in the subsequent cleaning liquid losing 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 leaks to the ground, causing the sewage to carry oil stains and pollute the soil, which is obviously contrary to the strict environmental protection requirements.

[0038] 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 storage barrels 555 that can be directly disassembled, and there are also non-integral upper covers of oil storage barrels 555. Workers can cut or directly remove the upper cover of the oil storage barrel 555 to be cleaned according to requirements. Then, the workers remove the fixed plate 5, and then press the upper part of the oil storage barrel 555 forward against the cover plate 101 and place it in the rotating frame 3. After the oil storage barrel 555 is placed, the workers reinstall the fixed plate 5. At this time, as Figure 2 and Figure 3 shown, the lower part of the oil storage barrel 555 is supported and limited by two electric rollers 7, the rear side of the oil storage barrel 555 is limited by the fixed plate 5, and the rotating plate 102 is in contact with the front side of the oil storage barrel 555 to seal the front side of the oil storage barrel 555, thereby preventing the oil storage barrel 555 from generating large shifts during the cleaning process, resulting in sewage splashing out and leakage. Then, the worker can control the equipment through the control box 4 to perform the cleaning operation on the oil storage barrel 555 described in the previous paragraph;

[0039] Furthermore, when there is a large amount of oil stains and impurities in the oil storage barrel 555, only by driving the rotating frame 3 to swing back and forth by the first motor 2, and then shaking the cleaning liquid in the oil storage barrel 555 to clean the inner wall of the oil storage barrel 555, it is difficult to clean the oil stains and impurities in the oil storage barrel 555 completely, and the oil stains and impurities cannot be discharged from the oil storage barrel 555 in time. Therefore, as Figures 3-5As shown: During the process of placing the oil tank barrel 555 into the rotating frame 3, the fixed rod 105 and the cleaning rod 106 will also enter the interior of the oil tank barrel 555. At this time, the bristles on the cleaning rod 106 come into contact with the inner wall of the oil tank barrel 555. Then the worker connects the water inlet pipe 8 to an external water pipe. It should be noted that the worker can prepare the alkaline cleaning potion in advance. The potion is pumped into the water inlet pipe 8 through the external water pipe, and then the oil stain is softened by the cleaning potion to improve the cleaning effect. Then the worker controls the first motor 2 to drive the rotating frame 3 to rotate through the control box 4, so that the oil tank barrel 555 is in an inclined state from the upper part at the rear to the lower part at the front. Then the worker places a collection bucket under the drainage plate 209, and then adds cleaning potion to the water inlet pipe 8 through the external water pipe. The cleaning potion will enter the water inlet groove 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 is sprayed relatively evenly by the sprayer 201 to wash the inner wall of the oil tank barrel 555. And the worker can increase the water injection pressure to improve the washing effect of the cleaning potion 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, so as to comprehensively wash the inner wall of the oil tank barrel 555 to improve the washing effect. 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 the cleaning block 204 is provided with a scraping blade, and the caked oil stains on the inner wall of the oil tank barrel 555 can be scraped by the scraping blade during the rotation of the cleaning block 204, which is convenient for the cleaning block 204 and the cleaning rod 106 to wash the inner wall of the oil tank barrel 555. And at this time, the worker can control the electric rotating plate 208 to rotate and open through the control box 4. Therefore, the larger oil stains and impurities cleaned in the oil tank barrel 555 will directly drain outwards into the collection bucket through the drain port 10201 and the drainage plate 209, so as to form a flowing cleaning potion in the oil tank barrel 555, quickly discharge the oil stains and impurities in the oil tank barrel 555, and improve the cleaning effect. When the larger oil stains and impurities in the oil tank barrel 555 are removed; in the oil tank barrel 555, the worker stops injecting the potion, then empties the potion in the oil tank barrel 555, and then controls the electric rotating plate 208 to rotate and close through the control box 4. Then new cleaning potion 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, so as to avoid the internal inflation of the sealed oil tank barrel 555 during the flushing process, resulting in cracks in the oil tank barrel 555 being opened by the inflation. Then the worker controls the first motor 2 to drive the rotating frame 3 to swing back and forth through the control box 4, and at the same time drives the oil tank barrel 555 to rotate, so as to shake the cleaning potion in the oil tank barrel 555 and remove the residual impurities in the oil tank barrel 555;

[0040] Further, as Figures 3-5As 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;

[0041] 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. Figures 4-6 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.

[0042] Example 2

[0043] On the basis of Example 1, Figures 2-5 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.

[0044] The working principle of the above embodiment is as follows:

[0045] Furthermore, when the prior art drives the oil tank barrel 555 to rotate through the electric roller 7 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 between the electric roller 7 and the outer side of the oil tank barrel 555 is poor at this time. Therefore, after the inner wall of the oil tank barrel 555 is cleaned, as Figure 4 and Figure 5 shown: When the air pump 205 injects gas into the telescopic airbag 206 so that the bristles on the cleaning rod 106 contact the inner wall of the oil tank barrel 555, the gas entering the air intake groove 10502 is controlled by the flow valve in the second connecting pipe 207, and then the extrusion force of the gas on the sliding rod 108 and the spring 109 is controlled, and then the moving distance of the sliding rod 108 and the cleaning rod 106 is controlled; when the outer surface of the oil tank barrel 555 needs to be cleaned; the air pump 205 continues to inject gas into the air intake 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, so that the magnet 203 contacts the inner wall of the oil tank barrel 555, and then the inner wall of the oil tank barrel 555 is magnetically attracted, and then the air pump 205 is controlled to stop injecting gas into the air intake groove 10502, and then as Figures 3-5 shown, with the front-to-back view as the reference, the fixed 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 force between the electric cleaning roller 9 and the outer surface of the oil tank barrel 555 is increased by reverse rotation, and the cleaning effect on the outer surface of the oil tank barrel 555 is improved; after the outer surface of the oil tank barrel 555 is cleaned, the gas in the air intake groove 10502 is pumped out by the air pump 205, and then the spring 109 slides the sliding rod 108, the cleaning rod 106 and the magnet 203 away from the inner wall of the oil tank barrel 555, and the magnetic attraction effect of the magnet 203 on the inner wall of the oil tank barrel 555 is released. It should be noted here that the restoring 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.

[0046] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the prior art well-known to those skilled in the art.
