As shown in fig. 8 and 9, the transfer assembly 100 includes a rotating base 101, a telescopic link 102, and a guide plate 103; the guide plate 103 is arranged at a right angle of the top surface of the power distribution cabinet and extends outwards of the power distribution cabinet, and the guide plate 103 is provided with a guide channel 1031; one end of the rotating base 101 is rotationally connected with the top surface of the power distribution cabinet, and the other end of the rotating base is provided with a telescopic hole 1011 along the horizontal direction; one end of the telescopic connecting rod 102 is arranged in the telescopic hole 1011 and slidingly connected with the rotating base 101, and the other end passes through the guiding channel 1031 and is rotatably connected with the housing 80. The one end that rotation base 101 and switch board top surface are connected is provided with the motor, motor and switch board top surface fixed connection, main control module 90 rotates base 101 through motor control on the horizontal plane, drive flexible connecting rod 102 and casing 80 and rotate together when rotation base 101 rotates, because the restriction of guide channel 1031 to flexible connecting rod 102, so flexible connecting rod 102 removes along the route of seting up of guide channel 1031, when the distance of guide channel 1031 from rotation base 101 is different, flexible connecting rod 102 can naturally stretch out and draw back and adjust, because flexible connecting rod 102 is rotation connection with casing 80, so casing 80 can remove along the edge of switch board when the angle of flexible connecting rod 102 and switch board is different. After the telescopic connecting rod 102 is moved from the first end to the second end of the guiding channel 1031, the housing 80 is then moved along the first face of the power distribution cabinet to the adjacent second face.

The guiding channel 1031 is L-shaped, two ends of the guiding channel 1031 are arranged along the extending direction of the top surface edge of the power distribution cabinet, and the width of the guiding channel 1031 is equal to the outer diameter of the telescopic connecting rod 102; when the telescopic connecting rod 102 is rotated to the first end of the guiding channel 1031, the side edge of the housing 80 is aligned with the side edge of the first face of the power distribution cabinet; when the telescopic connecting rod 102 is rotated to the second end of the guiding channel 1031, the side edge of the housing 80 is aligned with the side edge of the second face of the power distribution cabinet. Because the width of the guiding channel 1031 is equal to the outer diameter of the telescopic connecting rod 102, the distance between the shell 80 and the power distribution cabinet in the rotating process of the telescopic connecting rod 102 is kept unchanged, the shell 80 is always attached to the power distribution cabinet, and the first surface and the second surface of the power distribution cabinet are two adjacent surfaces, namely the front surface and the side surface of the power distribution cabinet, and the back surface and the side surface of the power distribution cabinet. After the movement of the housing 80 is completed, a side is always aligned with the side of the power distribution cabinet, so that the main control module 90 can conveniently position the detection sensor 70.

As shown in fig. 10 and 11, an elastic member 1012 is disposed in the telescopic hole 1011, and the elastic member 1012 abuts against the telescopic connecting rod 102; the telescopic connecting rod 102 is provided with a rotation gear 1021 at a guide channel 1031, a guide tooth 1032 is provided at a side of the guide channel 1031 away from the elastic member 1012, and the elastic member 1012 is used for controlling the rotation gear 1021 to be engaged with the guide tooth 1032. In the above embodiment, the width of the guiding channel 1031 is larger than the outer diameter of the rotating gear 1021, when the rotating base 101 rotates without the rotating gear 1021, friction is generated when the telescopic connecting rod 102 moves along the guiding channel 1031, and the rotating gear 1021 is arranged on the telescopic connecting rod 102, so that the telescopic connecting rod 102 is converted from the original sliding friction to the rotating friction of the gear, and the friction between the telescopic connecting rod 102 and the guiding channel 1031 is reduced. Preferably, the motor is not disposed on the rotation base 101 but disposed on the telescopic connection rod 102 for controlling the rotation of the rotation gear 1021, specifically, the motor selects an outer rotor motor, the upper end of the stator of the outer rotor motor is connected with the telescopic connection rod 102, the lower end is rotationally connected with the top surface of the housing 80, and the rotor of the outer rotor motor is connected with the inner wall of the rotation gear 1021 for controlling the rotation of the rotation gear 1021. When the motor is arranged on the rotating base 101 to rotate, certain torsion can be brought to the telescopic connecting rod 102, and when the motor is arranged on the telescopic connecting rod 102 to control rotation, the telescopic connecting rod 102 cannot generate torsion, and rotation of the power distribution cabinet is easier to realize.

As shown in fig. 10, the guiding channel 1031 is L-shaped, so as to form a first channel, a second channel and a junction channel, the first channel and the second channel are perpendicular to each other, and are communicated at the junction channel, the first channel and the second channel are respectively parallel to two adjacent surfaces of the power distribution cabinet, the length of the first channel is greater than the vertical distance between the rotation center of the rotation base 101 and the second channel, and the length of the second channel is greater than the vertical distance between the rotation center of the rotation base 101 and the first channel. Thus, when the telescopic connecting rod 102 rotates to the first end of the guiding channel 1031, that is, the end of the first channel away from the junction channel, the elastic force of the elastic member 1012 pushes the telescopic connecting rod 102 to move away from the junction channel, and the telescopic connecting rod 102 forms self-locking under the action of the elastic member 1012 because the telescopic connecting rod 102 is at the most distal end of the first channel; similarly, when the telescopic connecting rod 102 rotates to the second end of the guiding channel 1031, i.e. the end of the second channel away from the junction channel, the elastic force of the elastic member 1012 pushes the telescopic connecting rod 102 to move away from the junction channel, and the telescopic connecting rod 102 is self-locked under the action of the elastic member 1012 because the telescopic connecting rod 102 is at the most distal end of the second channel. The telescopic connecting rod 102 can automatically form self-locking after reaching the two ends of the guiding channel 1031, so that the shell 80 can be more stable after reaching the corresponding position, and the shell 80 can not move after the outer rotor motor is disconnected in the subsequent detection process.

As shown in fig. 12 and 13, since the power distribution cabinets are mostly arranged in a row in a set, the following modifications are required in order to be able to detect the fault location of a row of power distribution cabinets. Adopt the scheme of external rotor motor setting on flexible connecting rod 102, still include slip subassembly 110, rotate base 101 and slip subassembly 110 rotation connection through the subassembly 110 setting that slides on the top surface of switch board, rotate base 101, slip subassembly 110 is used for driving and rotates base 101 and move along the direction that the switch board was arranged. The sliding assembly 110 comprises a sliding rail 112 and a sliding block, the sliding rail 112 is connected with the top surface of the power distribution cabinet and extends along the arrangement direction of the power distribution cabinet, the sliding block 111 is connected with the sliding rail 112 in a sliding manner, and the first end of the rotating base 101 is connected with the sliding block 111 in a rotating manner. The main control module 90 drives the sliding block 111 to move through a motor. When the distance of the movement of the traverse frame 60 is insufficient, the transfer module 100 and the housing 80 need to be moved together by the slider 111. Correspondingly, the length of the first channel of the guiding channel 1031 needs to be the same as the length of the row of power distribution cabinets, when the sliding block 111 slides along the sliding rail 112, the outer rotor motor also needs to rotate, and when the linear speed of the rotating gear 1021 matches with the sliding speed of the sliding block 111, the transferring assembly 100 and the housing 80 can move along the first channel of the guiding channel 1031 together.

Preferably, the guide plate 103 is provided with a camera module connected with the main control module 90, and the camera module is used for monitoring the service condition of the power distribution cabinet and the state of the state detection device. The external control equipment can remotely check whether the power distribution cabinet has open fire or not through the camera module and check the use state of the state detection device.

The on-line digital state detection device for the power distribution cabinet realizes the detection of the fault position of the power distribution cabinet through the following processes: the main control module 90 controls the rotating base 101 to rotate to the first end of the guiding channel 1031, so that the detection sensor 70 is opposite to the first surface of the power distribution cabinet, the detection sensor 70 is controlled to move and detect the related data of the first surface, and the main control module 90 analyzes the data of the first surface of the power distribution cabinet and determines the coordinate axis of the fault position on the first surface; the main control module 90 controls the rotation base 101 to rotate to the second end of the guiding channel 1031, so that the detection sensor 70 is opposite to the second surface of the power distribution cabinet, the detection sensor 70 is controlled to move to the second surface of the power distribution cabinet and detect relevant data of the second surface, and the main control module 90 analyzes the data of the second surface of the power distribution cabinet and determines the coordinate axis of the fault position on the second surface. Through carrying out fault detection to two adjacent first faces and the second face of switch board, confirm the coordinate axis of trouble at first face and the coordinate axis of second face respectively to confirm the fault position in the switch board. The detection sensors 70 include ultrasonic sensors, ultrahigh frequency detection sensors 70, high frequency current detection sensors 70, and the like for detecting a power equipment failure, which each have a characteristic that the farther from the occurrence point, the smaller the value of the detected data. The position of the fault point is detected by the master control module 90 analyzing the progressive movement toward the fault point.

In order to make sure that the fault signal is occurring within the power distribution cabinet, the relevant data of the environment need to be detected, which comprises the following procedures: the main control module 90 controls the rotation base 101 to rotate to the first end or the second end of the guiding channel 1031, controls the detection sensor 70 to move to the outside detection related data of the first surface or to move to the outside detection related data of the second surface as the environmental data, and determines that the fault point is located outside the power distribution cabinet when determining that the environmental data is greater than the maximum data in the first surface or greater than the maximum data in the second surface. The above process is performed prior to the state detection of the power distribution cabinet, and after the fault position is determined to be in the power distribution cabinet, the state detection is performed on the power distribution cabinet.

In order to avoid the abnormality of the device itself from interfering with the detection result, the following procedure is required: when the main control module 90 controls the detection sensor 70 to detect, the outer rotor motor, the left transmission member 10 and the right transmission member 20 are controlled to be powered off. The related motor is disconnected each time the detection sensor 70 is controlled to collect data, so that the power structure of the detection device is prevented from interfering the detection result. Because the structure can form self-locking or the relative position is not influenced by power failure, the power failure of the motor does not interfere with detection.

Embodiment one: the coordinate axis of the fault location is determined by the following procedure:

the main control module 90 controls the detection sensor 70 to move to the middle position of the uppermost end and the lowermost end of the power distribution cabinet and detects related data, and the main control module 90 judges the larger two data in the three data of the uppermost end, the lowermost end and the middle position of the power distribution cabinet and judges whether the distance between the positions of the larger two data is smaller than the preset precision distance; the main control module 90 controls the detection sensor 70 to move to the middle position of the leftmost end and the rightmost end of the power distribution cabinet and detects related data, and the main control module 90 judges the larger two data in the leftmost end, the rightmost end and the middle position of the power distribution cabinet and judges whether the distance between the positions of the larger two data is smaller than the preset precision distance; when the main control module 90 determines that the distance between the positions of the larger two data is greater than or equal to the preset precision distance, the detecting sensor 70 is controlled to move to the middle point of the positions of the larger two data, relevant data are detected, and finally whether the distance between the positions of the larger two data is smaller than the preset precision distance is determined; when the main control module 90 determines that the distance between the positions of the two larger data is smaller than the preset precision distance, the position with the largest data is taken as the coordinate of the coordinate axis.

Embodiment two: the coordinate axis of the fault location is determined by the following procedure:

the main control module 90 judges the data size of the uppermost end and the lowermost end of the power distribution cabinet, controls the detection sensor 70 to move to one end with smaller data in the two ends of the power distribution cabinet, then controls the detection sensor 70 to move to one end with larger data and continuously detects related data on a moving path until the main control module 90 judges that the data on the path is equal to the larger data in the two ends of the power distribution cabinet, and takes the midpoint of the same position of the two data on the power distribution cabinet as the coordinate of an ordinate axis; the main control module 90 judges the data size of the leftmost end and the rightmost end of the power distribution cabinet, controls the detection sensor 70 to move to the end with smaller data in the two ends of the power distribution cabinet, then controls the detection sensor 70 to move to the end with larger data and continuously detects related data on the moving path until the main control module 90 judges that the data on the path is equal to the larger data in the two ends of the power distribution cabinet, and takes the midpoint of the same position of the two data on the power distribution cabinet as the coordinate of the abscissa axis.

Embodiment III: the coordinate axis of the fault location is determined by the following procedure:

the fault location is determined by dynamic monitoring, and three detection sensors 70 are needed in this detection mode, where the first detection sensor 70 and the second detection sensor 70 are respectively disposed at the bottoms of two detection side frames 62, and the third detection sensor 70 is disposed at the top of any one detection side frame 62. The present embodiment takes the detection side frame 62 in which the first detection sensor 70 and the third detection sensor 70 are disposed on the same side as each other as an example.

The main control module 90 detects the related data of the power distribution cabinet through the first detection sensor 70 and the second detection sensor 70, judges the data size of the two detection sensors 70, firstly controls the transverse sliding frame 60 to move along the direction of the detection sensor 70 with larger data, continuously detects the related data in the moving process, and judges that the fault position is positioned on the middle line of the vertical direction of the transverse sliding frame 60 until the data size of the two detection sensors 70 is the same because the related data of ultrasonic waves are transmitted along waveforms; and then controlling the horizontal sliding frame 60 to longitudinally move on the central line, detecting related data of the power distribution cabinet through the first detection sensor 70 and the third detection sensor 70 on the same side, judging the data size of the two detection sensors 70, and finally controlling the horizontal sliding frame 60 to longitudinally move towards the detection sensor 70 with larger data, continuously detecting the related data in the moving process until the data sizes of the two detection sensors 70 are the same, and judging that the fault position is positioned on the central line in the horizontal direction of the horizontal sliding frame 60. So far, it can be judged that the fault is located at the center position of the horizontal slip frame 60.

The fault occurring at different positions of the power distribution cabinet can be detected through the three fault position judging modes, and the speeds and the precision of the different detecting modes are different, so that the main control module 90 can couple the detecting modes, the fault position is comprehensively judged, and the accuracy of fault position detection is improved. The first and second embodiments have fast speed, low accuracy, and no limitation on detection range, and can perform the preliminary determination, and the third embodiment has slow speed, high accuracy, and can not detect the fault at the edge of the power distribution cabinet, and the main control module 90 further determines the fault location near the preliminary determined fault location by the third embodiment. When the main control module 90 judges that a fault point exists, scanning is continued for a plurality of times at intervals until the fault point scanned each time is located at the same coordinate, and then the fault point is reported to the external control equipment.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
