[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0020] Please refer to Figures 1 to 4 , a fault monitoring and diagnostic device for a power grid, comprising a monitor and a mobile carrier for hanging on a cable;

[0021] The monitor is arranged on a mobile carrier, the mobile carrier is provided with a threading hole for the cable to pass through, and a roller assembly is arranged on the inner side wall of the threading hole;

[0022] The mobile carrier is further provided with a driving control component, the driving control component is in transmission connection with the roller component, and the driving control component is used to drive the roller component to roll on the cable;

[0023] The mobile carrier is also provided with an independent power supply component, and the independent power supply component is electrically connected to the monitor and the drive control component respectively.

[0024] From the above description, it can be seen that the beneficial effect of the present invention is that the monitor used for fault monitoring and diagnosis is installed on the mobile carrier data collection, and the mobile carrier is sleeved on the cable through the threading hole. When different parts of the cable need to be inspected, the roller assembly is driven by the drive control assembly to roll on the cable, so that the device moves on the cable and then monitors. There is no need to install monitoring equipment at multiple positions on the cable and set the timing to collect multi-channel monitoring data, thereby reducing the cost of monitoring equipment and the difficulty of collecting monitoring data.

[0025] Further, the independent power supply assembly includes a solar panel 15 and a power module;

[0026] The solar panel 15 is arranged on the outer surface of the mobile carrier, and the power module is located inside the mobile carrier;

[0027] The solar panel 15 is electrically connected to the power module, and the power module is electrically connected to the monitor and the drive control component respectively.

[0028] From the above description, it can be seen that since the device is arranged on an outdoor cable for a long time, solar power is used to ensure that the device can operate independently and stably for a long time, while improving resource utilization.

[0029] Further, it also includes a cleaning brush 21 and a displacement control component;

[0030] The displacement control component is disposed on the outer surface of the mobile carrier and is located adjacent to a first side of the solar panel 15. The solar panel 15 has a second side opposite to the first side. One end of the cleaning brush 21 is connected to the displacement control component, and the other end of the cleaning brush 21 is disposed across the solar panel 15 and corresponds to the second side.

[0031] The bristles of the cleaning brush 21 are located on a side of the cleaning brush 21 facing the solar panel 15 , the displacement control component can drive the cleaning brush 21 to move in a direction parallel to the first side, and the independent power supply component is electrically connected to the displacement control component.

[0032] From the above description, it can be seen that since too much dust attached to the outside of the solar panel 15 will affect its conversion of light energy, a cleaning component consisting of a cleaning brush 21 and a displacement control component is provided. The cleaning brush 21 is controlled by the displacement control component to move back and forth above the solar panel 15, so that the bristles of the cleaning brush 21 sweep away the dust on the solar panel 15.

[0033] Further, the displacement control assembly includes a first motor 19 and a guide rod 18;

[0034] The guide rod 18 is disposed adjacent to the first side of the solar panel 15 and is parallel to the first side;

[0035] One end of the cleaning brush 21 close to the first side is in transmission connection with the guide rod 18, and the first motor 19 can drive the cleaning brush 21 to move along the guide rod 18;

[0036] The independent power supply assembly is electrically connected to the first motor 19 .

[0037] From the above description, it can be seen that in terms of movement control, one end of the cleaning brush 21 is set on the guide rod 18, and then the first motor 19 controls it to move linearly along the guide rod 18, thereby achieving stable operation and simplified control.

[0038] Furthermore, the displacement control assembly also includes a protective cover 16 and a rain detector 22;

[0039] The protective cover 16 is arranged on the outer surface of the mobile carrier, and a mounting groove 17 adapted to the guide rod 18 is arranged at the bottom of the protective cover 16, and the guide rod 18 is located in the mounting groove 17;

[0040] The rain detector 22 is disposed on the protective cover 16 , and the drive control component is electrically connected to the rain detector 22 and the displacement control component respectively.

[0041] From the above description, it can be seen that a protective cover 16 and a rain detector 22 are arranged on the surface of the device. The protective cover 16 can protect the connecting structure between the guide rod 18 and the cleaning brush 21. At the same time, the rain detector 22 is used to detect rainy weather, and combined with the rain falling on the solar panel 15, the cleaning effect of the cleaning brush 21 is more significant.

[0042] Further, the mobile carrier comprises an upper shell 11 and a lower shell 1;

[0043] The upper shell 11 is detachably connected to the lower shell 1. A first through slot is provided on a side of the upper shell 1 facing the lower shell 1. A second through slot opposite to the first through slot is provided on the lower shell 1. The first through slot and the second through slot are spliced ​​to form the threading through hole.

[0044] From the above description, it can be seen that the mobile carrier is composed of an upper shell 11 and a lower shell 1; accordingly, the threading hole is also formed by splicing a first through slot and a second through slot to facilitate disassembly and assembly of the entire device and maintenance of internal components.

[0045] Furthermore, the drive control assembly includes a switch 28, a main controller 26 and an indicator light 27;

[0046] The switch element 28, the main controller 26 and the indicator light 27 are distributed on a surface of the lower housing 1 facing the upper housing 11;

[0047] The upper housing 11 is provided with a first avoidance groove 32, a second avoidance groove 33 and a third avoidance groove 34 which correspond to the main controller 26, the indicator light 27 and the switch 28 in sequence.

[0048] The main controller 26 is electrically connected to the indicator light 27 , the switch 28 , the independent power supply assembly and the monitor respectively.

[0049] From the above description, it can be seen that the drive control part adopts the main controller 26 as the main control element, and the main controller 26 can be controlled by means of remote communication to operate the entire device. At the same time, it is equipped with a switch 28 and an indicator light 27 to facilitate daily maintenance; at the same time, corresponding avoidance grooves are set to improve the fit between the upper and lower shells 1.

[0050] Further, the roller assembly includes a second motor 13 and a rotating wheel 12;

[0051] At least two rotating wheels 12 are rotatably disposed in the threading through hole, a limiting groove 14 is provided in the movable carrier, and the second motor 13 is located in the limiting groove 14;

[0052] The second motors 13 correspond to the rotating wheels 12 one by one and are transmission-connected thereto. The independent power supply assembly is electrically connected to all the second motors 13 , respectively. All the second motors 13 can control the rotating wheels 12 to roll on the cables.

[0053] As can be seen from the above description, the roller assembly is controlled by a motor, and a plurality of rotating wheels 12 roll together on the cable to increase the driving force for the movement of the device.

[0054] Furthermore, a power supply connector 29 and a debugging connector 30 are provided on a surface of the lower housing 1 facing the upper housing 11;

[0055] The upper shell 11 is provided with a fourth avoidance groove 35 and a fifth avoidance groove 36 corresponding to the power supply connector 29 and the debugging connector 30 respectively;

[0056] The drive control component is electrically connected to the independent power supply component via the power supply connector 29 , and the debugging connector 30 is electrically connected to the drive control component.

[0057] From the above description, it can be seen that the power supply connector 29 and the debugging connector 30 are also arranged on the side of the lower shell 1 facing the upper shell 11, so as to facilitate wiring, debugging and other work when arranging the device, thereby improving convenience.

[0058] Furthermore, a sealing ring 38 is provided on the movable carrier at a position corresponding to the opening of the threading through hole.

[0059] It can be seen from the above description that by providing the sealing ring 38, the gap between the cable and the threading hole can be filled to prevent some foreign matter from entering the interior of the device and affecting its normal operation.
