[0034] like Figures 1-9As shown, this utility model discloses a tank cleaning device for an oil and gas storage and transportation tank, including an oil and gas storage and transportation tank body 1. A sealing pipe 2 is installed on the top of the oil and gas storage and transportation tank body 1, and inlet and outlet pipes are respectively connected to the outer surface of the front side and the bottom of the inner cavity of the oil and gas storage and transportation tank body 1. Cleaning components 3 are provided on the outer surfaces of both the left and right sides of the oil and gas storage and transportation tank body 1. The cleaning components 3 include a mounting box 31, and the outer surface of the mounting box 31 is fixedly connected to the outer surface of the oil and gas storage and transportation tank body 1. A rotating rod 32 is connected to the inner cavity of the mounting box 31. The outer surface of the rotating rod 32 located on the left side is provided with external threads, and... The top end of the rotating rod 32 is rotatably connected to the inner cavity of the mounting box 31. A movable plate 33 is movably connected to the outer surface of the rotating rod 32. The movable plate 33 on the left side has a matching internal thread at the connection point with the rotating rod 32, so that the connecting rod 35 can push the movable plate 33 up and down using the thread transmission principle. The outer surface of the movable plate 33 is slidably connected to the inner cavity of the mounting box 31. A first motor 34 is installed in the inner cavity of the mounting box 31. The output shaft of the first motor 34 is fixedly connected to the bottom end of the rotating rod 32. A connecting rod 35 is fixedly connected to the top of the movable plate 33. The connecting rod 35 is located away from the movable plate 32. A welding plate is fixedly connected to one side of plate 33. Four long rods 37 are fixedly connected to the bottom of the welding plate. The bottom ends of the long rods 37 penetrate into the inner cavity of the oil and gas storage tank body 1 and are fixedly connected to a placement plate 38. The area where the long rods 37 penetrate into the oil and gas storage tank body 1 is sealed. A protective box 39 is fixedly connected to the top of the placement plate 38. A second motor 310 is installed inside the protective box 39. The output shaft of the second motor 310 is fixedly connected to a running rod 311. The bottom end of the running rod 311 penetrates to the outer side of the bottom of the placement plate 38 and is fixedly connected to a disc 312. The area in contact with the protective box 39 and the placement plate 38 is sealed. The bottom of the disc 312 is fixedly connected to the positioning box 313. The inner cavity of the positioning box 313 is provided with two guide rods 314 arranged symmetrically from the inside to the outside. The area in contact with the positioning box 313 is sealed. The outer surface of the guide rods 314 is fixedly connected to two long plates 315. The side of the long plate 315 away from the guide rods 314 is fixedly connected to a cleaning plate 316 that contacts the inner wall of the oil and gas storage tank body 1. The cleaning plate 316 is made of soft cleaning material.

[0035] like Figures 2-9As shown, two meshing gears 317 are fixedly connected to the outer surfaces of the two guide rods 314. A third motor 318 is installed in the inner cavity of the positioning box 313. The second motor 310 and the third motor 318 are preferably waterproof models. Two bevel gears 319 are respectively connected to the output shaft of the third motor 318 and the outer surface of the guide rods 314, and the two bevel gears 319 mesh with each other. A water pump 320 is fixedly connected to the outer surface of the rear side of the oil and gas storage tank body 1. A fixing plate 321 is fixedly connected to the inner cavity of the oil and gas storage tank body 1. A transmission pipe 322 is installed on the inner side. The outlet end of the water pump 320 passes through the inner cavity of the fixed plate 321 and is connected to the transmission pipe 322. The inlet end of the water pump 320 is connected to the external cleaning liquid storage device, so as to facilitate the cleaning of the inner wall of the oil and gas storage tank body 1. Several nozzles 323 are connected to the outer surface of the bottom of the transmission pipe 322. The nozzles 323 are used in conjunction with the cleaning plate 316. The nozzles 323 are inclined and the nozzles of the nozzles 323 can be tapered, so as to diffuse the spray onto the inner wall of the oil and gas storage tank body 1.

[0036] Specifically, when cleaning the inner wall of the oil and gas storage tank body 1, the first motor 34 is first started. This motor drives the rotating rod 32 to rotate, and uses the threaded transmission principle to push the moving plate 33 to move up and down. The moving plate 33 then drives the long rod 37 and the cleaning plate 316 to move synchronously, achieving up-and-down wiping and cleaning of the inner wall of the oil and gas storage tank body 1. During the wiping process, the water pump 320 is started simultaneously, drawing the cleaning liquid into the transmission pipe 322 and spraying it evenly onto the inner wall of the oil and gas storage tank body 1 through the nozzle 323. Then, the third motor 318 is started, driving the disc 312 to rotate. The disc 312 drives the cleaning plate 316 to rotate synchronously through the positioning box 313, thereby achieving even wiping of the inner wall of the oil and gas storage tank body 1. After cleaning is completed, the cleaning plate 316 is raised and lowered to the top of the inner cavity of the oil and gas storage tank body 1 and put away by the cooperation of the rotating rod 32 and the moving plate 33. At this point, the third motor 318 is restarted, driving the bevel gear 319 to rotate. The bevel gear 319 meshes with the drive gear 317 to rotate, and the gear 317 drives the guide rod 314, the long plate 315, and the cleaning plate 316 to swing synchronously, thereby adjusting the angle of the cleaning plate 316 to keep it away from the inner wall of the oil and gas storage tank body 1, avoiding prolonged contact that could cause problems. This structure allows for flexible adjustment of the angle of the cleaning plate 316 during the cleaning process, facilitating repeated wiping of heavily adhered localized oil stains. Furthermore, when dealing with the curved inner wall and bottom area of ​​the oil and gas storage tank body 1, the angle can be adjusted to achieve uniform cleaning of the bottom, improving the overall cleaning effect and making it more convenient and practical.

[0037] The working principle of a tank cleaning device for oil and gas storage and transportation tanks: First, when cleaning the inner wall of the oil and gas storage and transportation tank body 1, the user can use the cleaning component 3 to evenly spray liquid and wipe the bottom of the inner wall and inner cavity of the oil and gas storage and transportation tank body 1. After cleaning, the cleaning plate 316 can be separated from the inner wall of the oil and gas storage and transportation tank body 1 by the cleaning component 3, so as to avoid the adhesion of the cleaning plate 316 to the inner wall of the oil and gas storage and transportation tank body 1 due to prolonged contact, and facilitate use.

[0038] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
