The guide plate 604 is higher than the lower side of the charging interface 602, so the position of the guide slot 511 engaged with the guide plate is higher than the positioning structure, and the rear side and the bottom of the assembly housing 508 are both provided with guide openings 509 for facilitating the guide plate 604 to enter the assembly housing 508 and contact with the guide slot 511.

The interface guard shield 603 with the vertical sliding connection of the walking dolly casing 601 of inspection device 1, be equipped with the confession on the walking dolly casing 601 the interface groove that the interface guard shield 603 stretches out, the interface guard shield 603 top is equipped with the deflector 604 that the rear end is trapezoidal direction end 5111, and the deflector 604 top surface is parallel with running gear 6 top, the top surface shape of direction end with the trapezoidal direction end 5111 looks adaptation of guide way 511, trapezoidal direction end 5111 is the guide structure that the open end interval is less than the other end. The structure realizes the left-right direction guide in the forward moving process of the walking mechanism 6 through the trapezoid guide structure.

The subassembly output mechanism that charges is including installing starter motor 502 and eccentric wheel 503 mechanism in the module casing 501 charges, eccentric wheel 503 mechanism is including installing eccentric wheel 503 and the linking frame 504 on starter motor 502's the output shaft, eccentric wheel 503 perpendicular to the automatic module 5 top that charges sets up, linking frame 504 is fixed subassembly outer frame 505 is upper, eccentric wheel 503 stretches into linking frame 504, the upper and lower both sides of eccentric wheel 503 contact respectively the roof of linking frame 504 with the roof of subassembly outer frame 505. When the eccentric wheel 503 rotates around an output shaft which is not at the center of the eccentric wheel, the connecting frame 504 and the assembly outer frame 505 are driven to move up and down in the charging module shell 501. Because the telescopic and rotatable movable positioning part 516 is abutted and positioned with the charging interface 602, when the charging assembly needs to be retracted, the charging assembly can be directly moved upwards without a complex moving process.

When the scheme is used for charging, firstly, the control module in the control box 4 corresponding to the storage battery 3 collects the residual electric quantity of the built-in battery 605 in the inspection device 1 through communication, and if the inspection device 1 needs to be charged, a signal is sent to prepare for charging. The control module built in the inspection apparatus 1 may determine whether or not to perform charging based on the remaining power of the built-in battery 605, establish a wireless connection with the control box 4 of the adjacent storage battery 3 when charging is necessary, and determine that the storage battery 3 that has passed through next in front is charged.

After the charged storage battery 3 is determined, when the storage battery reaches the rear side below the corresponding automatic charging module 5, the driving motor is started to drive the interface shield 603 to move upwards, and simultaneously, the interface is driven to rotate and extend obliquely. At this point the charging assembly output mechanism is activated, extending the charging assembly downward through the eccentric 503 mechanism, and the guide slot 511 of the charging assembly presses against the guide plate 604 of the interface shield 603. Due to the limitation of the track, the left-right deviation distance of the running mechanism 6 is limited, so that the entrance of the guide slot 511 can be controlled to ensure that the guide slot can accommodate the guide plate 604, and the trapezoidal guide end 5111 at the front end of the guide slot 511 can guide the charging assembly to move left and right to match the position of the guide plate 604 through the forward movement of the running mechanism 6. When the guiding plate 604 reaches the middle of the charging assembly, i.e. the trapezoidal guiding end 5111, the pressing effect of the guiding plate 604 on the guiding slot 511 makes the charging assembly parallel to the guiding plate 604, and the lower side of the charging interface 602 also presses the movable positioning member 516 to rotate the latter, and makes the latter contract if the rear end of the movable positioning member 516 abuts against the top of the walking mechanism 6 in the process. Under normal conditions, after the above rotation and contraction process, the top of the movable positioning member 516 is attached to the lower side of the charging interface 602, so that the arrangement direction of the extending mechanism of the charging connector 513 is opposite to the charging interface 602 in the positive direction, and the distance between the extending front charging connector 513 and the charging interface 602 is kept constant.

Walking mechanism 6 can't advance under above-mentioned condition, after receiving pressure sensors's feedback signal, walking mechanism 6 stops, and it then starts linear drive device 517 to charge joint 513 and stretch out the mechanism, stretch out the joint 513 that will charge, because linear drive device 517 also inclines to stretch out, consequently, the grafting strength that acts on the interface is the slant decurrent, consequently it can not promote walking mechanism 6 and move backward to charge joint 513 under the condition that can't the level moves backward before inserting tightly, and location sand grip 5162 supports at location slide 6021 front end at the grafting in-process, not only it is invariable to have prescribed a limit to charge the distance of interface 602 to linear drive device 517, and can restrict the interface 602 that charges and move backward, therefore this scheme can let the joint 513 that charges and the interface 602 that charges insert tightly reliably. After the full connection, the secondary battery 3 starts charging the internal battery 605. The linear driving device 517 may be an electric cylinder, a linear module, or other driving device for driving the charging connector 513 to move backward and extend out.

After charging is completed, the connection between the charging connector 513 and the charging interface 602 is released, and the linear driving device 517 reversely operates to withdraw the charging connector 513. The movable positioning component 516 is supported against the top of the traveling mechanism 6 again under the action of the telescopic spring 514, then the charging assembly output mechanism runs, the charging assembly directly moves upwards, and due to the fact that the positioning rotating shaft is arranged below the extending end of the charging interface 602, the traveling mechanism 6 is pushed backwards until the upper end of the charging interface 602 pushes the rear side of the positioning rotating shaft backwards, and the movable positioning component 516 is driven to rotate. The movable positioning member 516 rotates downwards and extends outwards at the same time until the movable positioning member 516 extends to the initial length and is blocked by the limiting structure of the hinged bottom plate 515, the movable positioning member 516 starts to rotate and ascend, when the movable positioning member 516 is separated from the charging interface 602, the retraction of the charging structure is completed, and the hinged bottom plate 515 is restored to the horizontal state again under the action of the gravity of the extending mechanism of the charging connector 513. The travel mechanism 6 can move forward again by retracting the interface shield 603 to continue the patrol.
