Therefore, a power line monitoring device that can be easily adjusted to adapt to different sizes is needed. And when installing cables with large spans and high erection positions, it is also easy to have inconvenient device installation, and workers need to climb to install and fix it. Therefore, a monitoring device that can move well, is convenient to adjust the installation position, and is convenient for fault location is needed. Summary of the Utility Model

The power transmission cable for transmitting power penetrates through the inside of the box body. Rotating pipes are arranged on both sides of the two ends of the box body close to the power transmission cable. Pressing rings are sleeved on the outer walls of the top and bottom of the rotating pipes. A rotating component is installed at the bottom of the rotating pipe on one side of the box body close to the power transmission cable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0027] The present utility model provides as Figures 1-5An on-line monitoring device for power line fault location, including a box body 1, a rotating pipe 2 and a pressing ring 3. The power transmission cable 6 for transmitting power passes through the inside of the box body 1. Rotating pipes 2 are arranged on both sides of the two ends of the box body 1 close to the power transmission cable 6. Pressing rings 3 are sleeved on the outer walls of the top and bottom of the rotating pipe 2. A rotating component 5 is installed at the bottom of the rotating pipe 2 on one side of the box body 1 close to the power transmission cable 6. A fixing block 4 is sleeved on the outer wall of the bottom of the rotating pipe 2 on the side far from the rotating component 5; A threaded rod 201 is arranged through the inside of the rotating pipe 2 for extrusion. A plurality of rectangular holes 202 are formed in the outer wall of the rotating pipe 2, and a driving motor 203 is arranged at the bottom of the threaded rod 201; A central ring 301 is arranged at the center of the pressing ring 3 for extrusion, and the central ring 301 is threadedly connected with the outer wall of the threaded rod 201. The central ring 301 passes through the inside of the rectangular hole 202 and is fixed to the pressing ring 3.

[0028] As Figure 2 , Figure 4 shown, a lead screw 401 is threadedly connected to one side of the fixing block 4 for adjustment, and a rotating motor 402 is installed at one end of the lead screw 401 close to the rotating component 5; A rotating motor 402 is arranged at one end of the lead screw 401 close to the rotating component 5. The power output end of the rotating motor 402 is fixed to the lead screw 401. The outer wall of the rotating motor 402 is fixed to the inner wall of the box body 1. Starting the rotating motor 402 will cause the lead screw 401 to rotate. Since the fixing block 4 is threadedly connected to the lead screw 401 and the fixing block 4 is connected to the outer wall of the rotating pipe 2 through penetration and rotation, the rotation of the lead screw 401 can drive the fixing block 4 to move. By moving the fixing block 4, the rotating pipe 2 on one side of the power transmission cable 6 can be driven to approach and press it, so as to facilitate fitting different sizes of power transmission cables 6.

[0029] As Figure 2 , Figure 3 shown, the power output ends at the top of the driving motor 203 are fixedly connected to the threaded rod 201. The driving motor 203 on the side of the power transmission cable 6 far from the rotating component 5 slides with the inner bottom end of the box body 1, and the driving motor 203 on the side close to the rotating component 5 is fixed to the inside of the box body 1. Thus, the rotation of the rotating pipe 2 and the relative movement with the power transmission cable 6 can drive the box body 1, so as to facilitate the movement and position adjustment along the power transmission cable 6 without manual operation.

[0030] As Figure 4As shown, the rotating assembly 5 for driving includes a driven gear 501 and a driving gear 502. The driven gear 501 is fixedly connected to the outer wall of the bottom of the rotating tube 2. The driven gear 501 meshes with the driving gear 502. A rotating motor 503 is installed at the bottom of the driving gear 502. The power output end of the rotating motor 503 is fixedly connected to the inner center of the driving gear 502. The rotating motor 503 is fixedly connected to the inside of the box body 1. Starting the rotating assembly 5 causes the rotating motor 503 to rotate. Then, the rotating motor 503 can drive the driven gear 501 to rotate through the driving gear 502. Then, the driven gear 501 drives the rotation of the rotating tube 2.

[0031] As Figure 2 , Figure 3 shown, the central ring 301 is slidably connected to the inside of the rotating tube 2. The inclined surfaces of the pressing rings 3 at both ends of the outer wall of the rotating tube 2 are inclined towards the center to form a conical shape. The top of the box body 1 is inclined towards both sides and provided with cover plates 101. Accommodation grooves 102 are provided at the corresponding positions of both ends of the box body 1 and the power transmission cable 6. A sensor detection module 103 is installed at the bottom end inside the box body 1. A signal transmission module is installed inside the box body 1, which can conveniently detect and find faults in the power transmission cable 6 through the sensor detection module 103, and at the same time perform remote monitoring through the communication module.

[0032] During use, the cover plate 101 on the top of the box body 1 can be conveniently opened, and then the power transmission cable 6 can be placed at the accommodation grooves 102 on both sides of the top of the box body 1, so that the rotating tubes 2 are respectively located on both sides of the power transmission cable 6. Then, the rotating motor 402 can be conveniently started, causing the lead screw 401 to rotate. Since the fixed block 4 is threadedly connected to the lead screw 401 and the fixed block 4 is connected to the outer wall of the rotating tube 2 through penetration, the rotation of the lead screw 401 can drive the fixed block 4 to move. The movement of the fixed block 4 can drive the rotating tube 2 on one side of the power transmission cable 6 to approach it, so as to conveniently adapt to power transmission cables 6 of different sizes for fitting. At the same time, the driving motor 203 can be started to rotate, causing the driving motor 203 to drive the top threaded rod 201 to rotate. Since the threaded rod 201 is threadedly connected to the central ring 301 and the central ring 301 passes through the rectangular hole 202 and is fixed to the pressing ring 3, when the threaded rod 201 rotates, the two central rings 301 can be driven to approach each other, and then the two pressing rings 3 are driven to approach each other, thus realizing the extrusion of the top and bottom of the power transmission cable 6 by the pressing rings 3, further maintaining the fit and preventing detachment. At the same time, through the adjustment of the pressing rings 3, the fitting and clamping of power transmission cables 6 of different sizes can be adapted. At this time, it is convenient to detect and find faults in the power transmission cable 6 through the sensor detection module 103, and at the same time perform remote monitoring through the communication module.

[0033] When installing the device in a cable with a relatively large span, the box body 1 can be easily clamped to one end of the transmission cable 6. Therefore, when the rotating tube 2 is in contact with the transmission cable 6, the rotating assembly 5 can be started, so that the rotating motor 503 rotates. Then, the rotating motor 503 can drive the driven gear 501 to rotate through the driving gear 502. Then, the driven gear 501 drives the rotation of the rotating tube 2, so that the rotating tube 2 rotates and moves relative to the transmission cable 6, and the box body 1 can be driven, and thus the position can be adjusted by moving along the transmission cable 6 conveniently without manual operation. At the same time, when in use, the lead screw 401 can be rotated in the reverse direction, and then the rotating tube 2 can be driven to move in the reverse direction through the fixing block 4, so as to avoid squeezing the transmission cable 6 too tightly and facilitate moving and adjusting the position of the box body 1.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
