[0002] The BeiDou differential positioning-based conductor sag online monitoring device is used in power systems to monitor the sag status of overhead transmission conductors in real time with high precision. It primarily utilizes BeiDou differential positioning technology to accurately measure the spatial coordinates of different positions on the conductor. By analyzing this coordinate data, it determines the changes in conductor sag. Current BeiDou differential positioning-based conductor sag online monitoring devices are inconvenient to stably install sensors on the conductors; therefore, a BeiDou differential positioning-based conductor sag online monitoring device is needed.

[0003] Existing online sag monitoring devices for conductors based on BeiDou differential positioning are inconvenient to use because it is difficult to stably install the sensor on the conductor and to slide the sensor to the center of the conductor's sag, thus affecting the monitoring accuracy. Therefore, there is an urgent need for an online sag monitoring device for conductors based on BeiDou differential positioning. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an online monitoring device for conductor sag based on BeiDou differential positioning, so as to solve the problems of existing online monitoring devices for conductor sag based on BeiDou differential positioning, which make it inconvenient to stably install the sensor on the conductor and to slide the sensor to the center of the conductor sag.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for conductor sag based on BeiDou differential positioning, comprising a first clamping plate, a first semi-threaded column fixedly connected to the outer wall of the first clamping plate, a rotating shaft installed on the outer wall of the first clamping plate, a second clamping plate installed on the outer wall of the rotating shaft, a second semi-threaded column fixedly connected to the outer wall of the second clamping plate, a first nut installed on the outer wall of the second semi-threaded column, and a second nut installed on the outer wall of the second semi-threaded column.

[0006] A support rod is fixedly connected to the inner wall of the second clamping plate. A frame plate is fixedly connected to one end of the support rod. A rotating rod is installed inside the frame plate. An insulated pulley is fixedly connected to the outer wall of the rotating rod.

[0007] A sensor is installed at the bottom of the first clamp, a protective cover is installed on the outer wall of the sensor, and a bandage is fixedly connected to the outer wall of the protective cover.

[0008] Preferably, the first clamping plate and the second clamping plate form a rotating structure through a rotating shaft, and both the first clamping plate and the second clamping plate are semi-arc-shaped.

[0009] Preferably, the second semi-threaded post is threadedly connected to the first nut, and the second semi-threaded post is threadedly connected to the second nut.

[0010] Preferably, the support rods are arranged symmetrically about the central axis of the frame plate, and the frame plate is arranged in a ring around the central axis of the second clamping plate.

[0011] Preferably, the frame plate forms a rotating structure through a rotating rod and an insulated pulley, and the frame plate is U-shaped.

[0012] Preferably, the protective cover is snapped into connection with the sensor, and the bandage is elastic.

[0013] Preferably, the protective cover has a slotted design, and the bandage is fitted onto the outer wall of the first clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a first clamping plate, a first half-threaded post, a rotating shaft, a second clamping plate, a second half-threaded post, a first nut, a second nut, and a sensor, allows the first clamping plate to be sleeved on the wire. By pulling the second clamping plate and under the action of the rotating shaft, the second clamping plate can be rotated along the first clamping plate, so that the first half-threaded post and the second half-threaded post are connected. At this time, the first half-threaded post and the second half-threaded post form a complete threaded post. By connecting the first nut and the second nut to one end of the threaded post and rotating them, the first half-threaded post and the second half-threaded post can be limited, which facilitates the installation of the sensor on the wire.

[0016] 2. This utility model, through the setting of a first clamping plate, a second clamping plate, a frame plate, an insulating pulley, and a sensor, allows the first clamping plate to be released. Under the action of gravity, the first clamping plate and the second clamping plate can be moved towards the center sag of the conductor, so that the insulating pulley can rotate along the frame plate. This facilitates the sliding and transporting of the sensor to the center sag of the conductor, thereby facilitating real-time monitoring of the conductor's sag data.

[0017] 3. This utility model, through the setting of a first clamping plate, sensor, protective cover and bandage, by putting the bandage on the first clamping plate, pulling the protective cover outward, at this time moving the protective cover to the bottom of the sensor, releasing the protective cover, under the action of elasticity, can make the bandage return, causing the protective cover to lock and wrap around the outer wall of the sensor, thereby achieving the effect of facilitating the protection of the sensor.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-4 The online monitoring device for conductor sag based on Beidou differential positioning includes a first clamping plate 1, a first semi-threaded post 2 fixedly connected to the outer wall of the first clamping plate 1, a rotating shaft 3 installed on the outer wall of the first clamping plate 1, a second clamping plate 4 installed on the outer wall of the rotating shaft 3, a second semi-threaded post 5 fixedly connected to the outer wall of the second clamping plate 4, a first nut 6 installed on the outer wall of the second semi-threaded post 5, and a second nut 7 installed on the outer wall of the second semi-threaded post 5. The first clamping plate 1 and the second clamping plate 4 form a rotating structure through the rotating shaft 3, and both the first clamping plate 1 and the second clamping plate 4 are semi-arc-shaped. The second semi-threaded post 5 is threadedly connected to the first nut 6 and the second semi-threaded post 5 is threadedly connected to the second nut 7, which facilitates the installation of the sensor 12 on the conductor.

[0026] Please see Figure 1-4 The online monitoring device for conductor sag based on Beidou differential positioning has a support rod 8 fixedly connected to the inner wall of the second clamping plate 4. One end of the support rod 8 is fixedly connected to a frame plate 9. A rotating rod 10 is installed inside the frame plate 9. An insulating pulley 11 is fixedly connected to the outer wall of the rotating rod 10. The support rod 8 is symmetrically arranged with the central axis of the frame plate 9, and the frame plate 9 is arranged in a ring with the central axis of the second clamping plate 4 as the center. The frame plate 9 forms a rotating structure with the rotating rod 10 and the insulating pulley 11. The frame plate 9 is U-shaped, which can facilitate the sliding and transporting of the sensor 12 to the center sag of the conductor.

[0027] Please see Figure 1-4The online monitoring device for conductor sag based on Beidou differential positioning has a sensor 12 installed at the bottom of the first clamping plate 1. A protective cover 13 is installed on the outer wall of the sensor 12. A bandage 14 is fixedly connected to the outer wall of the protective cover 13. The protective cover 13 and the sensor 12 are snapped together. The bandage 14 is elastic. The protective cover 13 has a slotted design. The bandage 14 is fitted onto the outer wall of the first clamping plate 1, which can facilitate the protection of the sensor 12.

[0028] Working principle: In use, by placing the bandage 14 on the first clamping plate 1 and pulling the protective cover 13 outward, the bandage 14 can be deformed. At this time, the protective cover 13 is moved to the bottom of the sensor 12 and released. Under the action of the elastic force, the bandage 14 can be restored, causing the protective cover 13 to lock and wrap around the outer wall of the sensor 12. The first clamping plate 1 is placed on the wire, and the second clamping plate 4 is pulled. Under the action of the rotating shaft 3, the second clamping plate 4 can be rotated along the first clamping plate 1, so that the first half-threaded post 2 and the second half-threaded post 5 are connected. At this time, the first half-threaded post 2 and the second half-threaded post 5 form a complete threaded post. The first nut 6 and the second nut 7 are respectively connected to one end of the threaded post and rotated. Since the second half-threaded post 5 is divided into The first nut 6 and the second nut 7 are not threaded together, which limits the first half-threaded post 2 and the second half-threaded post 5, so that the first clamping plate 1 and the second clamping plate 4 are fitted on the outer wall of the conductor, and the three insulating pulleys 11 are just in contact with the conductor. By releasing the first clamping plate 1, under the action of gravity, the first clamping plate 1 and the second clamping plate 4 can move towards the center sag of the conductor, so that the insulating pulleys 11 rotate along the frame plate 9, driving the sensor 12 to move to the sag of the conductor. The sensor 12 receives the Beidou satellite signal and provides the conductor sag data as signal feedback, so that the conductor sag data can be monitored in real time. This completes the use of the device. The contents not described in detail in this specification are the prior art known to those skilled in the art.
