Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning mechanisms, in particular to an oil and gas storage and transportation tank cleaning device. Background Art

[0002] When oil and gas storage and transportation tanks are used for a long time, a large amount of oil stains are easily accumulated on their inner surface, and a cleaning device is needed to clean the oil and gas storage and transportation tanks. When existing cleaning devices are used to clean oil and gas storage and transportation tanks, cleaning dead corners are very likely to appear, which reduces the cleaning effect of the cleaning device on the oil and gas storage and transportation tanks.

[0003] After searching, it was found that a scheme of an oil and gas storage and transportation tank cleaning device (Announcement No. CN219766280U) includes an L-shaped mounting frame and an oil and gas storage and transportation tank body. A first motor is fixedly installed on the right side wall of the L-shaped mounting frame. The output end of the first motor passes through the L-shaped mounting frame and a hollow shaft is fixedly installed. The L-shaped cleaning brush can adapt to oil and gas storage and transportation tank bodies of different diameters through the connecting rod and the movable frame. The hollow shaft, the outer surface cleaning mechanism and the internal cleaning mechanism are driven to rotate by the first motor, and the surface of the oil and gas storage and transportation tank body is cleaned by the outer surface cleaning mechanism and the internal cleaning mechanism. The corners of the inner bottom of the oil and gas storage and transportation tank body are cleaned by the L-shaped cleaning brush, thereby improving the cleaning quality. However, the device does not take into account the cleaning of the inner surface of the oil and gas storage and transportation tank body, and it is very easy to have cleaning dead corners, which reduces the cleaning effect of the cleaning device on the oil and gas storage and transportation tank body.

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] In order to solve the problem that the cleaning device of oil and gas storage tanks is prone to cleaning dead corners when cleaning the oil and gas storage tanks, which reduces the cleaning effect of the cleaning device on the oil and gas storage tanks, please refer to Figures 1 to 4 The structure of the device body is an oil and gas storage tank 1 and a cleaning component 2 for cleaning the inner surface of the oil and gas storage tank 1. The cleaning component 2 is extended into the interior of the oil and gas storage tank 1 and rotated to achieve the cleaning effect on the inner surface of the oil and gas storage tank 1. The cleaning component 2 includes a rotating rod 3 and a rotating frame 4. A sliding rod 5 is welded to the inner wall of the rotating frame 4. Two sliders 6 are slidably connected to the side of the sliding rod 5, so that the two sliders 6 move along the path of the sliding rod 5. At the same time, the top and bottom surfaces of the two sliders 6 are slidably connected to the rotating frame 4, further improving the movement of the two sliders 6. The two side surfaces of the slider 6 are rotatably connected to the rotating frame 4, further improving the movement of the two sliders 6. The two sides of the slider 6 are connected with movable plates 7 through pin shafts.

[0027] The end faces of the two movable plates 7 are rotatably connected to the movable plate 8 by a pin shaft, and the two movable plates 7 rotatably connected to the movable plate 8 are respectively located on the sides of two different sliders 6, so that when the two sliders 6 move centrifugally, the two movable plates 8 are centrifugally moved under the connection provided by the four movable plates 7, thereby realizing the transmission of the movement of the device component structure. The moving end of the electric telescopic rod 10 is welded to the side of the movable plate 8, and the fixed end of the electric telescopic rod 10 is detachably connected to the fixed plate 11 by a bolt. The set electric telescopic rod 10 provides power to make the moving ends of the two electric telescopic rods 10 move synchronously in opposite directions, thereby making the two movable plates 8 move centrifugally, and the adjacent sides of the two fixed plates 11 are welded to the rotating frame 4.

[0028] The end of the movable plate 8 away from the electric telescopic rod 10 is welded with a vertical scraper 9 for scraping off oil stains on the inner wall of the oil and gas storage tank 1, and then the two vertical scrapers 9 are centrifugally moved, so that the vertical scrapers 9 are in contact with the inner wall of the oil and gas storage tank 1, thereby cleaning the inner surface of the oil and gas storage tank 1. At the same time, since the material mouth of the oil and gas storage tank 1 is small, the two vertical scrapers 9 are moved centripetally to achieve the contraction of the cleaning component 2, which facilitates the movement of the cleaning component 2 in and out of the oil and gas storage tank 1, thereby improving the convenience of using the device. Horizontal scrapers 12 are welded on both end faces of the vertical scraper 9, and the arranged horizontal scrapers 12 provide a cleaning effect on the inner top wall and inner bottom wall of the oil and gas storage tank 1.

[0029] The end face of the rotating frame 4 is welded to the rotating rod 3, and the top surface of the rotating rod 3 is connected to the output shaft of the rotating motor 13 through a coupling. The fixed end of the rotating motor 13 is detachably connected to the mounting plate 14 through bolts, so that the output shaft of the rotating motor 13 rotates, and the cleaning component 2 rotates during the transmission process to achieve the cleaning effect on the inner surface of the oil and gas storage and transportation tank 1. The moving end of the electric push rod 15 is welded to the top surface of the mounting plate 14. The power is provided by the set electric push rod 15, which facilitates the adjustment of the longitudinal position of the cleaning component 2, thereby reducing the cleaning dead angle of the cleaning device on the inner surface of the oil and gas storage and transportation tank 1, and improving the cleaning effect of the cleaning device on the oil and gas storage and transportation tank 1.

[0030] The bottom surface of the oil and gas storage tank 1 is abutted with a support plate 17, and an inverted U-shaped support frame 16 is welded on the top of the support plate 17. The inner top wall of the support frame 16 is embedded in the fixed end of the electric push rod 15, and a through groove is provided on the top surface of the support frame 16. The inner wall of the through groove of the support frame 16 is detachably connected to the fixed end of the electric push rod 15 by bolts. A groove is provided on the top surface of the support plate 17, and the inner wall of the groove of the support plate 17 is rotatably connected to a threaded rod 18 with a reverse thread. The threaded rod 18 is threadedly connected to two threaded blocks 19 with reverse threads. The set support plate 17 fixes the rotation position of the threaded rod 18, and at the same time makes the two threaded blocks 19 with reverse threads move in opposite directions along the threaded path of the threaded rod 18 with reverse threads. The side surfaces and bottom surfaces of the two threaded blocks 19 are slidably connected to the support plate 17. An L-shaped connecting plate 20 is welded on the top surface of the threaded block 19, and the set connecting plate 20 provides a connecting function.

[0031] The end face of the connecting plate 20 is welded with a clamping plate 21 that fits with the outer wall of the oil and gas storage tank 1. The adjacent sides of the two clamping plates 21 abut against the oil and gas storage tank 1, so that the two clamping plates 21 move centripetally to achieve clamping and fixation of the oil and gas storage tank 1, and prevent the oil and gas storage tank 1 from shaking and deviating when cleaning, thereby improving the cleaning effect of the cleaning device on the inner surface of the oil and gas storage tank 1. A drive motor 22 is installed on the side of the support plate 17, and the fixed end of the drive motor 22 is detachably connected to the side of the support plate 17 by bolts, and the output shaft of the drive motor 22 is connected to the threaded rod 18 through a coupling.

[0032] The electric telescopic rod 10, the rotating motor 13, the electric push rod 15, and the drive motor 22 are all prior art. Their working principles, sizes, and models are irrelevant to the functions of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by a technician in this field. The power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0033] How it works

[0034] When using the oil and gas storage tank cleaning device, the user places the cleaning component 2 on the inner wall of the oil and gas storage tank 1, moves the movable ends of the two electric telescopic rods 10, and then pushes the vertical scraper 9 to move through the movable plate 8, so that the two vertical scrapers 9 are in contact with the inner wall of the oil and gas storage tank 1. At the same time, the movable plate 7 is provided to provide a connection, so that the two sliders 6 move along the path of the slide rod 5, and the rotating motor 13 and the electric push rod 15 are started, so that the cleaning component 2 is driven to rotate during the rotation of the output shaft of the rotating motor 13, and the longitudinal position of the cleaning component 2 is controlled during the movement of the movable end of the electric push rod 15.

[0035] Start the drive motor 22. The output shaft of the drive motor 22 drives the threaded rod 18 with reverse threads to rotate during its rotation, thereby causing the two threaded blocks 19 with reverse threads to move along the threaded path of the threaded rod 18. The threaded blocks 19 drive the connecting plate 20 to move, thereby causing the two clamping plates 21 to clamp the oil and gas storage tank 1 during the centripetal movement.
