move upwards due to the threaded connection of the driven bevel gear 19 with the threaded guide rod 13, and then the driving bevel gear 18 and the driven shaft 17 are driven to move upwards so as to drive the beam 53 to move upwards, so that the threaded shaft 41 and the driven belt wheel 69 are driven to move upwards, so that the moving block 34 is driven to move upwards until the cleaning cavity 75 is aligned with the charging core 15 and then the control motor 47 stops rotating, at the moment, the control electromagnet 43 is electrified so as to drive the motor block 46 to move leftwards, the control motor 47 drives the driving shaft 49 to move leftwards until the driving shaft 49 is in splined connection with the threaded shaft 41, at the moment, the control motor 47 is started so as to drive the control spline 48 to rotate, the control spline 48 is in splined connection with the threaded shaft 41 so as to drive the threaded shaft 41 to rotate, the threaded shaft 41 is in threaded connection with the moving block 34 so as to drive the moving block 34 to move leftwards, when the charging core 15 is about to extend into the cleaning cavity 75, the cleaning motor 40 is started, the driving gear shaft 39 drives the driving gear 38 to rotate, and the driving gear 38 is in meshed connection with the front and rear driven gears 36 so as to drive the front and rear driven gears 34 to drive the front driven gears 34 and rear driven teeth to move leftwards The wheel 36 rotates, the front and rear side sleeves 59 are driven to rotate by the front and rear side driven gear shafts 37, the charging core 15 is cleaned under the action of the cleaning cotton cloth 57, the sleeves 59 rotate to drive the extrusion shaft 77 and the extrusion transmission gear 72 to rotate around the center of the sleeves 59 in the cleaning process, the extrusion transmission gear 72 is meshed with the annular rack 70 to drive the extrusion transmission gear 72 to rotate, so as to drive the extrusion shaft 77 to rotate, the extrusion chamber 64 is driven to move rightwards due to the threaded connection of the extrusion shaft 77 and the extrusion chamber 64, so that the lubricating oil on the left side of the rubber plate 21 in the extrusion cylinder 63 is extruded to the spherical surface of the annular rack 71 through the oil pipe 65, the annular racks 71 move in the far direction due to the extrusion action of the charging core 15 on the annular rack 71, the lubricating oil on the spherical surface of the annular rack 71 is immersed in the cleaning cotton cloth 57 and coated on the surface of the charging core 15 in the cleaning process, when the left end face of the moving block 34 contacts with the right end face of the telescopic block 60, the control motor 47 stops rotating and then reversely rotates to drive the moving block 34 to move rightwards to an initial horizontal position, then the control motor 47 and the cleaning motor 40 stop rotating, at the moment, the control electromagnet 43 is powered off, the control motor 47 continues to reversely start after the control spline 48 is in spline connection with the driving shaft 49, the moving block 34 is driven to completely reset, then the control motor 47 stops rotating, in the process, the annular rack 71 extrudes the supporting plate 54 to cause the supporting plate 54 to move towards the direction away from each other, so that the connecting rod 79 is driven to rotate, the supporting plate 67 is driven to move towards the direction close to each other through the right supporting rod 66, when the charging core 15 is bent and deformed, the pressure of the supporting plate 67 is increased, when the pressure exceeds a specified value, the control motor 47 and the cleaning motor 40 stop rotating, then the control motor 47 reversely rotates to drive the moving block 34 to move rightwards to a limit position and then stop rotating, meanwhile, the adjusting electromagnet 29 is electrified to adsorb the adjusting spline 27, the adjusting motor 31 stops rotating after the adjusting motor 31 is continuously started until the telescopic block 60 and the telescopic shaft 30 are in a threaded connection state, the whole device is powered off, an alarm is given to inform a worker to replace the telescopic block 60, the adjusting motor 31 is reversely started after the replacement is powered on until the telescopic block 60 is reset, the adjusting electromagnet 29 is powered off, and the motor 47 is controlled to be started to repeat cleaning actions.

The invention has the beneficial effects that: the invention relates to a new energy automobile battery charging device, which is provided with a plug capable of adjusting the distance between a positive electrode and a negative electrode, can charge batteries of different brands, and also comprises a plug cleaning device, wherein the plug cleaning device can clean the plug before each use, can detect the bending deformation degree of the plug in the cleaning process, can automatically replace the plug when the bending of the plug is detected, prevents electric energy waste caused by heating due to poor contact at an interface, and can also avoid potential safety hazards such as fire, electric leakage and the like.
