[0002] The Chinese patent publication number CN119426310A discloses an oil tank cleaning robot, which uses a mobile chassis and cleaning components to send the equipment into the oil tank, and drives the equipment to move autonomously in the oil tank through the mobile chassis. The vacuum suction pump truck provides suction power for the suction pipe to extract the sludge in the oil tank. At the same time, the drive unit drives the crushing knife to rotate and crush the hard sludge in the sludge. The oil tank cleaning robot can not only replace manual entry into the oil tank for dredging, but also crush the hard sludge in the sludge, thereby improving the dredging efficiency.

[0003] Since oil tanks are usually hollow cylindrical, impurities such as sludge may remain on the side walls of the tanks. Usually, the inside of the tank is sprayed and cleaned with a high-pressure nozzle. However, when solidified sludge is encountered on the side walls of the tanks, manual entry is still required to scrape it off, resulting in low cleaning efficiency. Summary of the Invention

[0004] In order to overcome the disadvantage that when cleaning the solidified sludge on the side wall of the oil tank, manual labor is still required to enter the side wall of the tank to scrape it, resulting in low cleaning efficiency, the present invention provides an intelligent chemical cleaning machine for oil storage tanks.

[0015] Compared with the existing technology, the present invention has the following advantages: the present invention controls the start-up of the electric drive wheel, drives the collecting bucket and the parts on it to move forward through the electric drive wheel, and then shovels up and collects the oil sludge at the bottom of the oil tank body through the collecting bucket, and the telescopic plate scrapes off the oil sludge on the side wall of the oil tank body. Under the action of its own gravity, the scraped oil sludge slides along the side wall of the oil tank body into the collecting bucket for collection.

[0016] By opening a cleaning groove with an L-shaped cross section on the telescopic plate, the cleaning groove accommodates the sludge when the telescopic plate scrapes it. Then, the external delivery pump is controlled to start and high-pressure cleaning liquid is delivered to the cleaning groove through the connecting pipe.

Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0021] Example 1: A chemical intelligent cleaning machine for oil tanks, such as Figures 1-10 As shown, it includes an oil tank body 1; It also includes a collecting bucket 101, a hook 102, an electric drive wheel 103, a motor I 104, an electric push rod 105, a telescopic plate 106, a suction pipe 107, a guide plate 108 and a motor II 1011; two hooks 102 are provided on the top of the collecting bucket 101; four electric drive wheels 103 are rotatably connected to the bottom of the collecting bucket 101; two motors I 104 are bolted to the top of the collecting bucket 101; two electric push rods 105 are rotatably connected to the collecting bucket 101, and the electric push rods 105 are fixedly connected to the output shafts of the corresponding motors I 104; the two ends of the opening of the collecting bucket 101 are respectively rotatable. There is a telescopic plate 106 that is dynamically connected, and the telescopic end of the telescopic plate 106 is rotatably connected to the telescopic end of the corresponding electric push rod 105, and the telescopic plate 106 is set in an arc shape of a quarter circle; the collecting bucket 101 is fixedly connected to two guide plates 108, and the guide plates 108 are located at the bucket mouth of the collecting bucket 101, and the two guide plates 108 are set in an eight-shaped shape; a number of motors II 1011 are bolted to the rear of the guide plate 108, and the output shaft of the motor II 1011 is fixedly connected to the fixed end of the corresponding telescopic plate 106; a number of suction pipes 107 are set in the collecting bucket 101.

[0022] The surface of the telescopic plate 106 is provided with an anti-stick coating to increase the friction between the telescopic plate 106 and the side wall of the oil tank body 1, thereby improving the cleaning effect of the side wall of the oil tank body 1.

[0023] A rubber scraper is provided at the bottom of the guide plate 108. When the bottom of the guide plate 108 contacts the inner wall of the oil tank body 1, the rubber scraper enhances the airtightness between the bottom of the guide plate 108 and the inner wall of the oil tank body 1.

[0024] It also includes saw teeth 1010; the collecting bucket 101 is fixed with a plurality of saw teeth 1010, and the saw teeth 1010 are located at the bucket mouth of the collecting bucket 101.

[0025] It also includes a rubber strip 1012; each telescopic plate 106 is fixedly connected to a rubber strip 1012; each telescopic plate 106 is provided with a cleaning groove 1061, and the cross section of the cleaning groove 1061 is L-shaped.

[0026] It also includes a delivery pipe 1014 and a hollow tube 1013; the delivery pipe 1014 is fixedly connected; the delivery pipe 1014 is connected to several hollow tubes 1013, and the hollow tube 1013 is fixedly connected to the collecting bucket 101, and the pipe mouth of the hollow tube 1013 is located at the bucket mouth position of the collecting bucket 101, and a filter is set at the pipe mouth of the hollow tube 1013, and the filter is used to prevent oil sludge from entering the hollow tube 1013.

[0027] Facing Figure 1 The direction is used as a reference to distinguish the front, back, left and right directions. Initially, the present invention is in a folded state. Figure 10 As shown, when in use, connect the hose of the external delivery pump to the connecting pipe 109, connect the hose of the external suction pump to the suction pipe 107, then fix it on the hook 102 through the external lifting tool, and then put the present invention vertically downward from the tank mouth of the oil tank body 1 to the inner bottom of the oil tank body 1, then control the electric push rod 105 to extend, thereby driving the telescopic end of the telescopic plate 106 to extend, and at the same time, control the motor I 104 to start, and drive the telescopic plate 106 to rotate through the output shaft of the motor I 104 until the telescopic plate 106 is in close contact with the inside of the oil tank body 1, as shown in FIG. Figure 2 and Figure 3 As shown, then, the electric drive wheel 103 is controlled to start, and the electric drive wheel 103 drives the collecting bucket 101 and the parts thereon to move forward, and then the collecting bucket 101 shovels up the oil sludge at the bottom of the oil tank body 1 and collects it, and the telescopic plate 106 scrapes the oil sludge on the side wall of the oil tank body 1. Under the action of its own gravity, the scraped oil sludge slides along the side wall of the oil tank body 1 into the collecting bucket 101 for collection, and there is no need to manually enter the interior of the oil tank body 1 to scrape the oil sludge on the side wall. Compared with the existing method of using high-pressure spraying, the telescopic plate 106 can The sludge on the side wall of the oil tank body 1 is removed to improve the cleaning effect of the oil tank body 1. Since the sludge will settle to the bottom of the oil tank body 1 under its own gravity, the amount of sludge remaining on the side wall of the oil tank body 1 is less than that on the bottom of the oil tank body 1. Therefore, the sludge in the lower half area of ​​the oil tank body 1 is cleaned only by the telescopic plate 106 arranged in a quarter circle and arc shape. During the cleaning process, the external delivery pump is controlled to start and the cleaning liquid is delivered to the connecting pipe 109 so that the cleaning liquid sprays the side wall of the oil tank body 1, thereby improving the efficiency of removing the sludge on the side wall of the oil tank body 1.

[0028] By arranging two guide plates 108 in an eight-shaped arrangement at the mouth of the collecting hopper 101, the sludge at the bottom of the oil tank body 1 is directed into the collecting hopper 101, thereby increasing the collection range of the collecting hopper 101 and improving the collection effect. At the same time, the sludge scraped off by the telescopic plate 106 and the cleaning liquid flushed are directed into the collecting hopper 101, thereby improving the sludge collection efficiency.

[0029] The collecting bucket 101 drives the saw teeth 1010 to move during the movement, so that the saw teeth 1010 separate the oil sludge at the bottom of the oil tank body 1, making it easier for the collecting bucket 101 to scoop up and collect the oil sludge.

[0030] When the telescopic plate 106 scrapes the front side wall of the oil tank body 1, the telescopic plate 106 cannot move relative to the oil tank body 1. Figure 8As shown, the sludge remaining in the contact part between the telescopic plate 106 and the front side wall of the oil tank body 1 cannot be scraped off, so that the sludge remains in the area between the telescopic plate 106 and the front side wall of the oil tank body 1. At this time, a cleaning groove 1061 with an L-shaped cross-section is opened in the telescopic plate 106, and when the telescopic plate 106 scrapes the sludge, the cleaning groove 1061 accommodates the sludge. Then, the external delivery pump is controlled to start, and high-pressure cleaning liquid is delivered to the cleaning groove 1061 through the connecting pipe 109, so that the cleaning liquid performs high-pressure flushing on the front side wall area of ​​the oil tank body 1 under the limit of the cleaning groove 1061, thereby improving the cleaning efficiency.

[0031] When the telescopic plate 106 approaches the front side wall of the oil tank body 1, the rubber strip 1012 fits against the front side wall of the oil tank body 1, so that the rubber strip 1012 seals the gap between the cleaning groove 1061 and the front side wall of the oil tank body 1, thereby preventing the high-pressure cleaning liquid from overflowing from the gap between the cleaning groove 1061 and the front side wall of the oil tank body 1.

[0032] When the telescopic plate 106 scrapes the front side wall of the oil tank body 1, some sludge and cleaning liquid will remain at the mouth of the collecting bucket 101 and cannot be sucked away by the suction pipe 107. Therefore, when the hollow tube 1013 is sucked by an external suction pump, the hollow tube 1013 will suck away the sludge and cleaning liquid remaining at the mouth of the collecting bucket 101, thereby improving the cleaning effect of the oil tank body 1.

[0033] Example 2, based on Example 1, Figure 6-Figure 7 As shown, it also includes a connecting ring 203, a cutter 202 and a motor 205; the collecting bucket 101 is fixedly connected to the motor 205; the collecting bucket 101 is rotatably connected to two connecting rings 203, and one of the connecting rings 203 is fixedly connected to the output shaft of the motor 205; the two connecting rings 203 are commonly fixedly connected to a number of cutters 202, and the cutters 202 are distributed in a ring shape.

[0034] It also includes a spray pipe 201; the collection bucket 101 is fixedly connected with the spray pipe 201, and the spray pipe 201 is located in the middle of the cutter 202; each spray pipe 201 is provided with a plurality of circular holes 2001.

[0035] The collecting bucket 101 further includes a limiting plate 204 ; the limiting plate 204 is fixedly connected to the inner side of the collecting bucket 101 , and the limiting plate 204 is fixedly connected to the suction pipe 107 .

[0036] The cutter 202 is detachably connected to the connecting ring 203. The cutter 202 will be greatly worn after crushing the oil sludge for a long time. Therefore, by detachably connecting the cutter 202 to the connecting ring 203, the cutter 202 can be quickly replaced.

[0037] The hose of the external delivery pump is connected to the spray pipe 201 at the same time. When the collecting bucket 101 shovels the oil sludge into the collection bucket, the motor 205 is controlled to start. The connecting ring 203 is used through the output shaft of the motor 205 to drive the cutter 202 to rotate counterclockwise from left to right, so that the cutter 202 breaks the oil sludge, which is convenient for the suction pipe 107 to suction and reduce the probability of blockage. At the same time, the oil sludge is continuously sent into the collecting bucket 101 during the rotation process, thereby improving the collection efficiency. The oil sludge sent into the collecting bucket 101 after being crushed is limited and diverted by the limiting plate 204, and the oil sludge is diverted to the pipe mouth on the lower side of the suction pipe 107, thereby improving the suction efficiency of the oil sludge.

[0038] During the process of the cutter 202 crushing the oil sludge, the external delivery pump is controlled to start, and the cleaning liquid is delivered to the cleaning pipe 201 through the external delivery pump. After the cleaning liquid is sprayed out from the circular hole 2001, it moistens the oil sludge and softens the oil sludge, making it easier for the suction pipe 107 to suck and collect it. At the same time, the sprayed cleaning liquid flushes the oil sludge attached to the cutter 202, thereby improving the crushing effect of the cutter 202.
