For example: the coordinates of the nozzle 49 at a high position are (sinβ*La, H1-d-cosβ*L), and the coordinate values ​​can be corrected to be close to the actual data. Finally, based on the effective cleaning radius R of the nozzle 49, it is judged whether the nozzle 49 can clean the top inner wall and the upper side wall of the first dark bin 21 when it is at a high position; the control unit adjusts the telescopic length of the telescopic rod 48 to ensure that it is clean.

When the telescopic rod 48 descends and rotates by an angle of φ, a second sensor is triggered by the contact part at the lowest part of the first connecting port 241; the control unit calculates the position of the nozzle 49 in the first dark bin 21 according to β-φ, the length of the bracket d, the length a from the bracket to the first partition plate 24, the distance L from the first hinge shaft 471 to the nozzle 49, the height H1 of the tank body and the length L1 of the first dark bin 21, for example: the coordinates of the nozzle 49 at the low position are (sin (β-φ) * La, H1-d-cos (β-φ) * L), and the coordinate values ​​can be corrected to be close to the actual data. Finally, based on the effective cleaning radius R of the nozzle 49, it is judged whether the nozzle 49 can clean the bottom inner wall and the lower side wall of the first dark bin 21 at the low position; the control unit adjusts the telescopic length of the telescopic rod 48 to ensure that it is clean.

[0041] If the second dark chamber 23 needs to be cleaned precisely, the method in steps 2-4 can be repeated.

Step 3: After the first dark chamber (21) is cleaned, the nozzle (49) is driven again by the servo motor (41), the worm reducer (42) and the screw elevator (43) to descend and return to the bright chamber (22) to be in a vertical straight line state; Step 4: The rotating disk (32) is driven to rotate by the worm gear reduction motor (33), the teeth of the rotating disk, and the driving gear (34), so as to realize a 180° rotation of the nozzle (49); Step 5: After the rotation is completed, the nozzle (49) is driven to rise again through the servo motor (41), the worm reducer (42) and the screw elevator (43) to enter the second dark bin (23) through the second connecting port (251), and the second dark bin (23) is cleaned; Step 6: After the cleaning of the second dark chamber (23) is completed, the nozzle (49) is driven to descend to a vertical position again by the servo motor (41), the worm reducer (42) and the screw elevator (43). After reaching the designated position, the fully automatic cleaning device (3) is lifted out by the lifting device, thereby completing the entire process of cleaning the inner wall of the tank truck (1).

10. A method for cleaning the inner wall of a lithium battery electrolyte tank truck according to claim 8, comprising the following steps: Step 1: hoist the fully automatic cleaning device (3) onto the tank truck (1) by means of a hoist and correctly connect it with its flange (26); Step 2: After the connection is completed, the open bin (22) is cleaned. After the open bin (22) is cleaned, the nozzle (49) is driven by the servo motor (41), the worm reducer (42) and the screw elevator (43) to rise through the first connecting port (241) and enter the first dark bin (21); Step 3: When the second connecting rod (47) is lifted from the vertical state by an angle β, a first sensor is triggered by the contact portion at the uppermost part of the first connecting port (241), and the control unit calculates the position of the nozzle (49) in the first dark bin (21) based on β, the bracket length d, the distance L from the first hinge shaft (471) to the nozzle (49), the tank height H1, and the length L1 of the first dark bin (21), and then determines whether the nozzle (49) can clean the top inner wall and the upper side wall of the first dark bin (21) when in a high position based on the effective cleaning radius R of the nozzle (49); the control unit adjusts the telescopic length of the telescopic rod (48) to ensure that the cleaning is thorough; Step 4, start the telescopic rod (48) so that the distance between the nozzle (49) and the first hinge axis (471) becomes longer. When the telescopic rod (48) descends and rotates by an angle φ, a second sensor is triggered by the contact portion at the lowest part of the first connecting port (241); the control unit calculates the position of the nozzle (49) in the first dark bin (21) based on β-φ, the bracket length d, the distance L from the first hinge axis (471) to the nozzle (49), the tank height H1 and the length L1 of the first dark bin (21), and then determines whether the nozzle (49) can clean the bottom inner wall and the lower side wall of the first dark bin (21) when in a low position based on the effective cleaning radius R of the nozzle (49); the control unit adjusts the telescopic length of the telescopic rod (48) to ensure that the cleaning is thorough.
