[0047] The working principle of the present invention is as follows:

[0048] The trolley 3 pushes the cylinder 4 to the bottom of the automatic cleaning device, and the controller controls the fixed cylinder 105 to move to the top of the trolley 3. The cylinder 4 is positioned through the industrial camera 107 and the controller, thereby controlling the grabbing device 108 and the gravity ball 109 to extend into the inner hole of the cylinder 4, so that the gravity ball 109 completely touches the ground or touches the trolley 3.

[0049] The controller controls the telescopic oil cylinder 115 so that the hemispherical shell 113 abuts against the inner wall of the cylinder barrel 4. Since the cylinder barrel 4 may not be vertical, the following will occur: Figure 1 and Fig.14 In the state shown, the vehicle 103 is moved under the control of the controller, and the industrial camera 107 is combined to make the gravity ball 109 above the depression on the outer guide head 218 (such as Fig.15 , Fig.16 , Fig.17 The gravity ball 109 is lowered, and the gravity ball 109 enters the interior of the central column 203 through the second through hole 219 and the first through hole 217, and continues to be lowered, and the cylinder 4 enters the cylinder body 202, and the first spray hole 221 and the second spray hole 223 are controlled to spray water (the water injection nozzle 225 is connected to an external water pump, and the controller controls the water pump). After cleaning, the supporting ring 204 lifts the cylinder 4, and the transport device 1 places the cylinder 4 on the trolley 3.

[0050] The present invention has the following technical effects:

[0051] 1. The present invention can automatically identify the cylinder barrel through the transport device, and automatically grab the cylinder barrel on the trolley through the action of the controller, so that it can be moved over for cleaning and also transported back to the trolley after cleaning; more importantly, the cooperation of the lifting rope, the grabbing device and the gravity ball of the present invention makes the gravity ball completely touch the ground or touch the trolley when grabbing, and the lifting rope between the grabbing device and the gravity ball is in a relaxed state. When lifting, the gravity ball should be fully extended, and the lifting rope can also be partially extended. The above-mentioned structure and control method of the present invention can not only transport the common in a vertical state, but also transport the cylinder barrel in an inclined state, and then the gravity ball can first enter the center column through the outer guide head to play a guiding role (the depression of the outer guide head can further facilitate the entry into the center column), even if the cylinder barrel rotates, the cylinder barrel can be directly moved downward, and it will fall under the guidance of the gravity ball and the lifting rope.

[0052] 2. The cleaning device of the present invention can achieve cleaning well, and the cylinder can be lifted out after cleaning. The setting of the inner guide head facilitates the pulling out of the gravity ball.

[0053] 3. The present invention obtains the state of the gravity ball in real time through four industrial cameras, and controls the mobile vehicle at the same time.
