Description

Technical Field

[0001] This utility model relates to the field of power distribution network monitoring technology, specifically a comprehensive power distribution network monitoring device. Background Technology

[0002] The power distribution network consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. It plays an important role in distributing electrical energy in the power grid. Overhead lines mainly refer to overhead open lines, which are erected above the ground. They are transmission lines that use insulators to fix the transmission conductors to poles erected on the ground to transmit electrical energy. They are relatively easy to erect and maintain, and the cost is low. However, they are easily affected by weather and the environment, which can cause faults. At the same time, the entire transmission corridor occupies a large area of ​​land and is prone to causing electromagnetic interference to the surrounding environment. The main components of overhead lines include: conductors and lightning protection wires, poles, insulators, hardware, pole foundations, guy wires, and grounding devices. In the current technical field, because overhead lines are particularly long, often stretching for several kilometers or even tens of kilometers, it is very troublesome to manually troubleshoot faults such as line breaks or collapsed poles.

[0003] However, existing technologies only use cameras installed on poles to collect and monitor images of cables. However, the images are not clear at long distances, which makes it difficult to accurately monitor power distribution network cables. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a comprehensive monitoring device for power distribution networks, which can conveniently perform real-time inspection and monitoring of power distribution network cables, thereby improving the accuracy and precision of power distribution network cable monitoring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive monitoring device for power distribution networks, comprising a monitoring mechanism for moving and monitoring power distribution network cables. The monitoring mechanism includes: a moving block, which is fitted onto the cable through a limiting groove at its bottom; a moving component, which is disposed within the limiting groove and controls the moving block to move on the cable; a monitoring camera, which is disposed on the top of the moving block through an adjustment structure and controls the monitoring camera to rotate up, down, left, and right on the moving block for real-time inspection and monitoring of the power distribution network cables; and a counterweight component, which is disposed at the bottom of the moving block and controls the center of gravity of the moving block to be located below the opening of the limiting groove.

[0006] Preferably, the moving component includes: multiple drive wheels, rotatably disposed within the limiting groove at equal intervals along the length direction of the limiting groove opening; multiple drive gears, disposed within the moving block and correspondingly disposed on one end of the multiple drive wheels; multiple transmission gears, correspondingly disposed between adjacent drive gears and meshing with the drive gears; and a fixed rod, passing through the moving block and rotatably connecting the multiple drive wheels and the multiple drive gears on one side, wherein one of the drive gears is driven by a motor.

[0007] Preferably, the counterweight assembly includes: two first rotating rods, whose length direction is parallel to the length direction of the limiting groove opening and symmetrically arranged on the bottom of the moving block about the limiting groove, and the bottom of the first rotating rods has a rotating groove; two second rotating rods, which are respectively rotatably inserted into the rotating grooves; two storage blocks, which are respectively arranged on different second rotating rods; and a control component, which is arranged on the moving block and controls the two second rotating rods to rotate synchronously in opposite directions along their respective axes.

[0008] Preferably, the monitoring mechanism further includes a positioning component for positioning the cable within the limiting groove. The positioning component includes: two positioning blocks, which are correspondingly disposed on adjacent ends of the storage block; multiple sets of positioning wheels, which are located one-to-one below multiple drive wheels, with two positioning wheels in each set, and are rotatably disposed on adjacent ends of the two positioning blocks; when the adjacent ends of the two positioning blocks are in contact, the end faces of the two positioning wheels in each set are in contact, and a positioning groove that mates with the surface of the cable is provided on the adjacent side.

[0010] Preferably, the control structure includes: a control screw, the length direction of which is perpendicular to the length direction of the linkage rack, and is inserted between the two linkage racks and driven by a motor; a linkage block, which is threadedly sleeved on the control screw; and two linkage rods, which are symmetrically arranged about the control screw, with their adjacent ends rotatably connected to the linkage block and their opposite ends rotatably connected to the adjacent ends of the two linkage racks.

[0011] The beneficial effects of this utility model are:

[0012] 1. The moving block is fitted onto the cable via a limiting groove. By setting the moving component within the limiting groove, the moving block can be controlled to move along the cable, enabling comprehensive inspection of the distribution network cables.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0021] Please see Figure 1-3A comprehensive monitoring device for power distribution networks includes a monitoring mechanism for moving and monitoring power distribution network cables. The monitoring mechanism includes: a moving block 1, which is fitted onto the cable through a limiting groove 8 at its bottom; a moving component, which is set in the limiting groove 8 and controls the moving block 1 to move on the cable; a monitoring camera 7, which is set on the top of the moving block 1 through an adjustment structure 6 and controls the monitoring camera 7 to rotate up, down, left, and right on the moving block 1 for real-time inspection and monitoring of the power distribution network cables; and a counterweight component, which is set at the bottom of the moving block 1 and controls the center of gravity of the moving block 1 to be located below the opening of the limiting groove 8.

[0022] like Figure 1-3 As shown, a drone can transport the mobile block 1 to the power distribution cable. For example, two electromagnets are installed on the top of the mobile block 1 and on the drone's support. During the process of the drone controlling the mobile block 1 to move onto the cable, the adjacent ends of the two electromagnets are controlled to have opposite magnetic poles, thus attracting each other. This allows the drone to move the mobile block 1. The limiting groove 8 at the bottom of the mobile block 1 is fitted onto the cable, and the moving component moves within the limiting groove 8, allowing for comprehensive inspection of the power distribution cable. This mobile monitoring method is significantly more efficient than traditional manual inspection or fixed-point monitoring. This significantly improves inspection efficiency and coverage. The monitoring camera 7, mounted on top of the moving block 1 via an adjustable structure, can capture the cable's status in real time, including its appearance and surrounding environment. This provides maintenance personnel with intuitive monitoring data and ensures the accuracy and precision of the collected data. The adjustable structure 6 allows the monitoring camera 7 to rotate up, down, left, and right on the moving block 1. This flexibility ensures the camera can capture various angles and details of the cable, improving the accuracy and comprehensiveness of monitoring. The counterweight component controls the center of gravity of the moving block 1 to be below the opening of the limiting groove 8, ensuring the stability of the moving block 1 as it moves along the cable. Furthermore, the counterweight component can be adjusted according to factors such as the cable's diameter and material to adapt to monitoring needs under different conditions.

[0023] The adjustment structure 6 in this application can be a camera adjustment bracket that controls the rotation of the camera's monitoring direction in the prior art.

[0024] The moving component includes: multiple drive wheels 9, which are rotatably arranged in the limiting groove 8 at equal intervals along the length of the opening of the limiting groove 8; multiple drive gears 13, which are arranged in the moving block 1 and are correspondingly arranged on one end of the multiple drive wheels 9; multiple transmission gears 14, which are correspondingly arranged between adjacent drive gears 13 and mesh with the drive gears 13; and a fixed rod 15, which passes through the moving block 1 and rotatably connects the multiple drive wheels 9 and the multiple drive gears 13 on one side, wherein one of the drive gears 13 is driven by a motor.

[0025] like Figure 1-3As shown, when the movable block 1 is fitted onto the power distribution cable through the limiting groove 8, the cable is located below multiple drive wheels 9. The drive gear 13 is rotated by the motor, and the two adjacent drive gears 13 are meshed by the transmission gear 14, which makes it easy to control the multiple drive gears 13 to rotate synchronously in the same direction, thereby driving the multiple drive wheels 9 to rotate on the cable and moving the movable block 1 on the cable.

[0026] The drive wheel 9 can be made of rubber. On the one hand, rubber has insulation properties, and on the other hand, it enhances the friction between the drive wheel 9 and the cable.

[0027] The counterweight assembly includes: two first rotating rods 3, whose length direction is parallel to the opening length direction of the limiting groove 8 and symmetrically arranged on the bottom of the moving block 1 about the limiting groove 8, and the bottom of the first rotating rods 3 has a rotating groove 4; two second rotating rods 5, which are respectively rotatably inserted into the rotating groove 4; two storage blocks 2, which are respectively arranged on different second rotating rods 5; and a control component, which is arranged on the moving block 1 and controls the two second rotating rods 5 to rotate synchronously in opposite directions along their respective axes.

[0028] Storage block 2 contains a storage power supply for powering the storage.

[0029] The monitoring mechanism also includes a positioning component for positioning the cable within the limiting groove 8. The positioning component includes: two positioning blocks 10, which are respectively set on the adjacent ends of the storage block 2; multiple sets of positioning wheels 11, which are respectively located below multiple drive wheels 9, with two positioning wheels 11 in each set, and are rotatably set on the adjacent ends of the two positioning blocks 10; when the adjacent ends of the two positioning blocks 10 are in contact, the end faces of the two positioning wheels 11 in each set are in contact, and a positioning groove that matches the surface of the cable is opened on the adjacent side.

[0030] The control components include: two control gears 12, which are fixedly mounted on different second rotating rods 5; two connecting gears 20, which are correspondingly mounted above the different control gears 12 and mesh with the control gears 12; two linkage racks 19, which are inserted into the moving block 1 and are correspondingly meshed above the different connecting gears 20, with the length directions of the two linkage racks 19 being collinear; and a control structure, which is located in the moving block 1 and controls the two linkage racks 19 to move closer to or further away from each other.

[0031] The control structure includes: a control screw 16, whose length direction is perpendicular to the length direction of the linkage rack 19 and is inserted between the two linkage racks 19, and is driven by a motor; a linkage block 17, which is threadedly connected to the control screw 16; and two linkage rods 18, which are symmetrically arranged about the control screw 16, with their adjacent ends rotatably connected to the linkage block 17 and their opposite ends rotatably connected to the adjacent ends of the two linkage racks 19.

[0032] The linkage rack 19 slides only along its length.

[0033] like Figure 1-3 As shown, during the placement of the movable block 1 on the cable, the motor first drives the control screw 16 to rotate, which in turn moves the linkage block 17 located on the control screw 16. At this time, due to the action of the two linkage rods 18, the two linkage racks 19 are pulled or pushed away from each other or closer to each other. In conjunction with the connecting gear 20 and the control gear 12, the two second rotating rods 5 are driven to rotate in opposite directions along their axes. This causes the two storage blocks 2 located below the movable block 1 to rotate away from each other. At this time, the movable block 1 can be fitted onto the cable through the limiting groove 8, and after the cable is located in the limiting groove 8... Then, by controlling the rotation of the lead screw 16, the two storage blocks 2 are driven to rotate and move closer to each other. At this time, the center of gravity of the moving block 1 and the two storage blocks 2 is located below the limiting groove 8, which ensures the stability of the moving block 1 during the movement on the cable. When the two storage blocks 2 move closer to each other, the positioning groove of the positioning wheel 11 set on the moving block 1 is in contact with the surface of the cable, so as to facilitate the stable contact of the cable with multiple drive wheels 9. This allows the moving block 1 to move on the cable by controlling the rotation of the drive wheels 9, and to cooperate with the monitoring camera 7 set on the moving block 1 to perform real-time inspection and monitoring of the cable.
