Description

Technical Field

[0001] This invention relates to the field of power transmission line inspection technology, and in particular to a device for monitoring debris around power grid distribution cables. Background Technology

[0002] A power distribution network generally consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. Among them, the power distribution lines of 10kV and below are characterized by a large number of nodes, wide distribution, and long line distances.

[0003] After power cables are installed, it is necessary to regularly monitor the surrounding area for obstructions, such as the growth of trees, to facilitate timely pruning and prevent branches from touching the cables, thus avoiding short circuits or tripping. Manual monitoring is labor-intensive and inefficient; therefore, a monitoring device for power grid distribution cables is needed. For example, Chinese Patent Publication No. CN116379308A describes a power grid distribution cable tree obstruction monitoring device. This device is connected to a utility pole via a frame, and a drive component moves the device upwards along the pole. The monitoring component then monitors the tree obstructions around the pole, significantly improving monitoring efficiency. However, in practical use, this device can only monitor tree obstructions near the utility pole. It only monitors the growth of trees near the cable and pole, and its effectiveness is poor for monitoring trees further away from the pole. Summary of the Invention

[0030] This patent relates to the field of cable monitoring technology, including a connector 1 and a monitoring component. The connector 1 is detachable from the cable. The monitoring component includes several arc-shaped connecting frames 2 connected end-to-end and a monitoring module. The inner sides of the arc-shaped connecting frames 2 are interconnected to form a ring-shaped guide rail 3. The monitoring module is fixed to the front and rear sides of the arc-shaped connecting frames 2. The outer side of the connector 1 has several guide rollers 4, which are in contact with the inner side of the guide rail 3. The connector 1 connects and supports the monitoring component, allowing it to move along the length of the cable. The monitoring component monitors the growth of trees around the cable. When trees grow close to the cable, it promptly alerts staff to prune the trees to prevent short circuits caused by tree branches or other obstacles coming into contact with the cable.

[0031] See Figure 1 , Figure 6 and Figure 7 As shown, this device includes a connector 1 and a monitoring section. The connector 1 is detachable from the power cable. The monitoring section includes several arc-shaped connector frames 2 connected end-to-end and a monitoring module. The several arc-shaped connector frames 2 are connected end-to-end to form a circular structure, such as... Figure 7 As shown, the two ends of the arc-shaped connecting frame 2 are bent outward to form bent ears. The bent ears are provided with fixing holes. Two arc-shaped connecting frames 2 are connected by bolts passing through the fixing holes on the bent ears. The inner sides of several arc-shaped connecting frames 2 are connected to form an annular guide rail 3. The monitoring module is fixed on the front side and the rear side of the arc-shaped connecting frame 2. The outer side of the connecting seat 1 has several guide rollers 4. The guide rollers 4 are in contact with the inner side of the guide rail 3.

[0032] The connector 1 is detachable from the wire. In the specific implementation process, as follows: Figure 2 As shown, the connector 1 has at least three limiting grooves 5 for connecting wires, and the limiting grooves are J-shaped and L-shaped. Figure 2 As shown, a J-shaped limiting groove is provided on the top of the connecting seat 1, and two L-shaped limiting grooves are mirror-symmetrically provided on the bottom of the connecting seat 1, with their closed ends facing away from each other. Through the cooperation of the three limiting grooves, the power cable cannot come out of the inside of the limiting groove at will, so that the power cable provides stable support for the connecting seat 1 and ensures that the connecting seat 1 remains vertical.

[0033] In a preferred embodiment, the bottom of the connecting seat 1 is provided with two horizontal first sliding seats, which are symmetrical about the central axis of the connecting seat 1. A first slider is slidably mounted on each of the first sliding seats, and each of the first sliders has an L-shaped limiting groove. A first stepper motor driving a bidirectional transmission screw is provided on the connecting seat 1 between the two first sliding seats. The two ends of the bidirectional transmission screw are coupled to the two first sliders respectively. The first stepper motor drives the two first sliders to move synchronously towards or away from each other along the first sliding seats via the bidirectional transmission screw, adjusting the distance between the two horizontal L-shaped limiting grooves.

[0034] In a preferred embodiment, a vertical second sliding seat is provided at the top of the connecting seat 1. A second slider is slidably mounted on the second sliding seat, and a J-shaped limiting groove is provided on the second slider. A transmission screw is provided on the second sliding seat, and the transmission screw is connected to a second stepper motor. The transmission screw is coupled to the second slider, and the second stepper motor drives the second slider to move along the second sliding seat through the transmission screw, adjusting the distance between the J-shaped limiting groove and the L-shaped limiting groove.

[0035] See also Figure 3 Figure 4 and Figure 5 As shown, the inner recess of the closed end of the limiting groove 5 forms a connecting groove, and a plurality of first drive rollers 6 are rotatably connected inside the connecting groove; the roller shaft of the first drive roller 6 is in contact with the power cable, and one end of the first drive roller 6 is connected to a first drive motor.

[0036] In the specific implementation process, depending on the diameter of the power cable, different numbers and lengths of first drive rollers 6 can be set to contact the power cable. The first drive motor drives the first drive rollers 6 to rotate, thereby driving the connecting seat 1 to move along the power cable.

[0037] See Figure 8 As shown, several guide rollers 4 are arranged in a circumferential array, with the axis of the guide rollers 4 parallel to the length direction of the power cable; and the axis of the guide rollers 4 is connected to a second drive motor. The contact surface between the guide rollers 4 and the guide rail 3 is rough to provide sufficient friction to drive the arc-shaped connecting frame 2.

[0038] In a preferred embodiment, an adjustable telescopic rod is mounted on the connecting seat 1, and a second drive motor is disposed at the end of the adjustable telescopic rod. The output shaft of the second drive motor is connected to the guide roller 4. The adjustable telescopic rod supports adjustment of the position of the guide roller, so that the connecting seat 1 can adapt to arc-shaped connecting frames 2 of different specifications. The diameter of the annular structure formed by the arc-shaped connecting frame 2 is designed according to the detection performance of the applied monitoring module and the obstacle clearing indicators around the power cables, so that when the monitoring module with the set detection performance is installed on the arc-shaped connecting frame 2, it can operate according to the obstacle clearing indicators.

[0039] as follows Figure 8 As shown, the side of the arc-shaped connecting frame 2 is recessed to form a mounting hole 7. The monitoring module is installed in the mounting hole 7, and the monitoring module includes an ultrasonic sensor 8. The ultrasonic sensor can also be replaced with an infrared obstacle avoidance sensor, a camera, or radar according to actual needs. Furthermore, to work with the ultrasonic sensor, infrared obstacle avoidance sensor, camera, or radar, this patent's monitoring module also includes a wireless communication module. In particular, to work with the camera, this patent's monitoring module also includes a power lamp component, which provides illumination to the camera.

[0040] This patented solution also includes a controller, the position of which is set by the operator according to the actual situation during operation. The controller is mainly used to control the electrical components used in this solution, including but not limited to a monitoring module, a first drive motor, a second drive motor, an adjustable telescopic rod, a wireless communication module, a first stepper motor, and a second stepper motor. The controller can be an Intel processor, an AMD processor, a PLC controller, an ARM processor, or a microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and a power supply. The power supply can be AC ​​power or a lithium battery; when a display screen is included, a graphics card is also included.

[0041] Specific usage instructions:

[0042] In practical use, a device for monitoring debris around power grid distribution cables first inserts the power cable into the limiting groove 5, with the first drive roller 6 contacting the power cable. Multiple arc-shaped connecting frames 2 are then connected to the outside of the connecting seat 1, allowing the power cable to pass through the interior of the arc-shaped connecting frames. The guide roller 4 on the outside of the connecting seat contacts the guide rail 3 on the inside of the arc-shaped connecting frame 2. Then, the first drive motor drives the first drive roller 6 to rotate, causing the connecting seat 1 to move along the length of the power cable. Simultaneously, while the connecting seat 1 moves, the second drive motor drives the guide roller 4 to rotate, causing the arc-shaped connecting frame 2 to rotate, which in turn drives the ultrasonic sensor 8 to rotate around the outside of the power cable. The ultrasonic sensor then monitors debris near the power cable, such as the growth of trees.
