Description

Technical Field

[0001] This utility model belongs to the field of rapid testing technology for overhead optical cables, specifically a hook-type portable rapid testing device for overhead optical cables. Background Technology

[0002] OPGW fiber optic composite overhead ground wire (referred to as O cable) serves as the core carrier for internal communication in the power system, undertaking key functions such as power grid dispatch command transmission and fault monitoring data feedback. Its operational stability is directly related to the safe and efficient operation of the power system. However, during daily operation, O cable is exposed to the natural environment for a long time and is susceptible to external factors such as tension changes, wind vibration, and lightning strikes, which can lead to fiber core breakage, attenuation, and other faults, thereby interrupting the power communication link and causing serious interference to power grid dispatch and operation and maintenance.

[0003] In handling O-cable faults, accurate fault location and rapid repair are the core elements to shorten the impact time of the fault. Traditional fault location methods rely on power outage operations and gradually investigate through manual inspections combined with instrument detection. This is not only time-consuming (usually several hours to several days) but also causes regional power outage losses, making it difficult to meet the high requirements of modern power grids for operation and maintenance efficiency.

[0004] Therefore, a portable, fast calibration device for overhead optical cables with a hook is proposed to address the above problems. Utility Model Content

[0008] Preferably, a through groove is provided on one side of the fixed shell at a position corresponding to the connecting plate and the positioning rod, and the connecting plate and the positioning rod both pass through the through groove.

[0009] Preferably, the horizontal rotation assembly includes a driven gear fixedly connected to the bottom of the fixed housing top surface, the driven gear being meshed with a driving gear, and the driving gear being connected to a drive motor via a motor shaft.

[0010] Preferably, a connecting bearing is installed at the center of the top of the driven gear, the connecting bearing is connected to a vertical rod, a support plate is fixedly connected to the outer wall of the vertical rod, and the drive motor is mounted on the support plate.

[0011] Preferably, the shock absorption assembly includes a bottom bracket fixedly connected to the top of the upright, a third spring connected to the center of the top of the bottom bracket, a top bracket connected to the top of the third spring, and a circumferentially distributed rubber rod between the top bracket and the bottom bracket. The two ends of the rubber rod pass through the top bracket and the bottom bracket respectively and are connected to rubber balls.

[0012] Preferably, a connecting rod is fixedly connected to the top center position of the top bracket, and limit holes are opened on both the top bracket and the bottom bracket at positions corresponding to the rubber rod, with both ends of the rubber rod passing through the limit holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The hook-type O-cable identifier of this utility model adopts an insulated hook-type structure, which is compatible with overhead O-cables. It has a built-in low-frequency wireless receiver and vibration triggering device, which can remotely receive commands to generate vibrations at a specific frequency. It not only meets the safety requirements of uninterrupted power operation, but also can accurately cooperate with the optical cable survey instrument to complete fault location and cable differentiation. The integrated design reduces external components and improves the stability of UAV mounting.

[0015] 2. The quick positioning connection assembly of this utility model achieves quick installation and disassembly of the hook-type O-cable identifier by inserting and removing the insertion plate and fixing shell, combined with the pre-tightening force of the first spring and the snap-fit ​​positioning of the positioning rod.

[0016] 3. The horizontal rotation component of this utility model drives the active gear and the driven gear to mesh and transmit power through the drive motor, so as to realize the 360° horizontal rotation of the hook-type O-cable identifier.

The spring and rubber rods absorb high-frequency vibrations during the flight of the UAV through elastic deformation. The rubber balls at both ends of the rubber rods further buffer the impact. The limiting holes of the top bracket and the bottom bracket constrain the rubber rods to avoid excessive deformation. This can reduce the interference of vibration on the precision components inside the recognition device, ensure the stability of the vibration trigger frequency, reduce structural fatigue when the UAV is mounted, and extend the service life of the device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, this utility model provides a hook-type portable overhead optical cable rapid verification device, including a hook-type O-cable identifier 1, a rapid positioning connection component 2 connected to the top of the hook-type O-cable identifier 1, a horizontal rotation component 3 connected to the top of the rapid positioning connection component 2, a shock-absorbing component 4 connected to the top of the horizontal rotation component 3, a connecting rod 5 connected to the top of the shock-absorbing component 4, and a drone connected to the connecting rod 5.

[0030] The hook-type O-cable identifier 1 adopts an insulated hook-type structure, which is compatible with overhead O-cables. It has a built-in low-frequency wireless receiver and vibration triggering device, which can remotely receive commands to generate vibrations at a specific frequency. This not only meets the safety requirements of uninterrupted power operation, but also accurately cooperates with the optical cable survey instrument to complete fault location and cable differentiation. The integrated design reduces external components and improves the stability of UAV mounting.

[0031] Specifically, the quick-positioning connection assembly 2 includes a fixed housing 201 with a bottom opening. An insertion plate 202 is disposed inside the fixed housing 201. A hook-type O-cable identifier 1 is fixedly connected to the bottom of the insertion plate 202. A lifting plate 203 is disposed near the top of the inner cavity of the fixed housing 201. A first spring 204 is connected to the top of the lifting plate 203. The top of the first spring 204 is connected to the inner wall of the top of the fixed housing 201. A connecting plate 205 is fixedly connected to one side of the lifting plate 203. A lifting housing 206 is fixedly connected to the connecting plate 205 through the fixed housing 201. The lifting housing 206 is located on one side of the fixed housing 201. The lifting shell 206 has an open structure on the side facing the fixed shell 201. A displacement plate 207 is provided inside the lifting shell 206. The displacement plate 207 moves against the inner wall of the lifting shell 206. A positioning rod 208 is fixedly connected to the side of the displacement plate 207 near the fixed shell 201. A positioning hole 209 is opened on the insertion plate 202 at the position corresponding to the positioning rod 208. A pulling rod 210 is fixedly connected to the side of the displacement plate 207 away from the positioning rod 208. The end of the pulling rod 210 passes through the lifting shell 206 and is connected to a pulling block 211. A second spring 212 is sleeved on the pulling rod 210 inside the lifting shell 206.

[0032] Furthermore, a through groove 213 is provided on one side of the fixed shell 201 at the position corresponding to the connecting plate 205 and the positioning rod 208, and the connecting plate 205 and the positioning rod 208 both pass through the through groove 213;

[0033] The quick-positioning connection assembly 2 achieves quick installation and disassembly of the hook-type O-cable identifier 1 by inserting and removing the insertion plate 202 and the fixed shell 201, combined with the preload of the first spring 204 and the snap-fit ​​positioning of the positioning rod 208. The second spring 212 inside the lifting shell 206 provides a continuous locking force for the positioning rod 208. The guiding design of the connecting plate 205 and the through groove 213 ensures accurate connection. The overall structure takes into account both the ease of operation and the stability of connection during high-altitude operations, and greatly shortens the operation time of the UAV with the identifier attached.

[0034] Furthermore, the horizontal rotation component 3 includes a driven gear 301 fixedly connected to the bottom of the fixed housing 201 and the top surface of the fixed housing 201. The driven gear 301 is meshed with a driving gear 302, and the driving gear 302 is connected to a drive motor 303 through a motor shaft.

[0035] It is worth noting that a connecting bearing 304 is installed at the top center of the driven gear 301, the connecting bearing 304 is connected to a vertical rod 305, a support plate 306 is fixedly connected to the outer wall of the vertical rod 305, and the drive motor 303 is installed on the support plate 306.

[0036] The horizontal rotation component 3 drives the active gear 302 and the driven gear 301 to mesh and transmit power through the drive motor 303, realizing the 360° horizontal rotation of the hook-type O-cable identifier 1. The connecting bearing 304 ensures that the rotation process is smooth and without jamming. The fixing structure of the upright 305 and the support plate 306 provides stable support for the drive motor 303. The orientation of the identifier hook can be flexibly adjusted to adapt to O-cables with different installation angles, effectively improving the success rate of splicing in complex overhead environments.

[0037] It is worth noting that the shock absorption component 4 includes a bottom bracket 401 fixedly connected to the top of the upright 305. A third spring 402 is connected to the center of the top of the bottom bracket 401. A top bracket 403 is connected to the top of the third spring 402. Rubber rods 404 distributed in a circumferential direction are provided between the top bracket 403 and the bottom bracket 401. Rubber balls 405 are connected to the two ends of the rubber rods 404 through the top bracket 403 and the bottom bracket 401, respectively.

[0038] It is worth mentioning that the connecting rod 5 is fixedly connected to the top center of the top bracket 403. Limiting holes 406 are opened on the top bracket 403 and the bottom bracket 401 at the positions corresponding to the rubber rod 404. Both ends of the rubber rod 404 pass through the limiting holes 406.

[0039] The shock absorption component 4 adopts a combination design of a third spring 402 and circumferentially distributed rubber rods 404. The spring and rubber rods 404 absorb high-frequency vibrations during the flight of the UAV through elastic deformation. The rubber balls 405 at both ends of the rubber rods 404 further buffer the impact. The limiting holes 406 of the top bracket 403 and the bottom bracket 401 constrain the rubber rods 404 to avoid excessive deformation. This not only reduces the interference of vibration on the precision components inside the identification device and ensures the stability of the vibration trigger frequency, but also reduces structural fatigue when the UAV is mounted, and extends the service life of the device.

[0040] It is worth emphasizing that the hook-type O-cable identifier 1 has an insulated hook-type structure and a built-in low-frequency wireless receiver and vibration triggering device.

[0041] Among them, the hook-type O-cable identifier 1 and the drive motor 303 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0042] Working principle and process: When installing the hook-type O-cable identifier 1, insert the insertion plate 202 at the top of the hook-type O-cable identifier 1 into the fixed housing 201. As the insertion plate 202 is inserted, it will squeeze the lifting plate 203 to move upward and compress the first spring 204. Then, the connecting plate 205 will drive the lifting housing 206 to move upward. At this time, the second spring 212 is in a compressed state and the positioning rod 208 is retracted into the lifting housing 206. As the lifting housing 206 moves upward, the positioning rod 208 moves upward along the outer wall of the fixed housing 201. When the positioning rod 208 moves to the position of the through groove 213, the positioning hole 209 also moves up to the same position. Under the elastic release of the second spring 212, the positioning rod 208 passes through the through groove 213 and extends into the positioning hole 209, thus fixing the insertion plate 202, which also fixes and connects the hook-type O-cable identifier 1. When it is necessary to remove the hook-type O-cable identifier 1, pull the pulling block 211 to make the positioning rod 208 move down after leaving the through groove 213, so that the insertion plate 202 can be separated from the fixing shell 201, which means removing the hook-type O-cable identifier 1. The cable identification device 1 and the drone are connected to the shock absorption assembly 4 via the connecting rod 5. After flying to the work area, the drive motor 303 of the horizontal rotation assembly 3 drives the active gear 302 to rotate. The active gear 302 meshes with the driven gear 301. Under the support of the connecting bearing 304, the upright 305 and the support plate 306 remain fixed. The driven gear 301 drives the fixed shell 201 and the structure below to rotate horizontally. The hook of the hook-type O-cable identification device 1 is adjusted to align with the O-cable. After the hook is attached, the built-in low-frequency wireless receiver of the hook-type O-cable identification device 1 receives the ground remote control signal and generates a specific frequency vibration of 200-300Hz (positioning) or 800Hz (identification) through the vibration triggering device. During this period, the third spring 402 of the shock absorption assembly 4 and the circumferentially distributed rubber rods 404 absorb the vibration generated by the drone flight through elastic deformation. The rubber ball 405 and the limiting hole 406 limit the excessive deformation of the rubber rods 404 to ensure the vibration stability of the identification device 1. Finally, in conjunction with the optical cable survey instrument, the fault point of the O-cable and the identification of the O-cable and ground wire are realized.
