DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] The utility model discloses a high-voltage transmission line 3 dancing monitoring device based on the Beidou navigation system, such as Figure 1-3As shown, it includes a power supply mechanism that can be detachably assembled inside the assembly shell, the assembly shell is detachably connected to the high-voltage transmission line 3, and a wireless communication module 6 is detachably connected on the lower end surface inside the assembly shell, the wireless communication module 6 is electrically connected to the power supply mechanism, and the wireless communication module 6 is electrically connected to the Beidou positioning module 7. The working principle of the utility model is: the assembly shell is detachably connected to the high-voltage transmission line 3, and the power supply mechanism inside the assembly shell supplies power to the Beidou positioning module 7 and the wireless communication module 6 to keep them running, and the Beidou positioning module 7 and the wireless communication module 6 are electrically connected. When the high-voltage transmission line 3 dances, the positioning information of the Beidou positioning module 7 changes, and this information is transmitted to the wireless communication module 6 in the form of an electrical signal. The wireless communication module 6 converts this electrical signal into a wireless signal and transmits it to the remote terminal, thereby achieving the purpose of monitoring the dancing condition of the high-voltage transmission line 3. Considering that real-time transmission of data will occupy a large bandwidth, the signal transmission frequency can be set in the wireless communication module 6 or data can be transmitted when the dancing amplitude reaches a certain value, thereby reducing the bandwidth occupied by remote communication. The beneficial effects of the utility model are as follows: since the device adopts the Beidou positioning module 7, it can monitor the swing and vibration and other status information of the high-voltage transmission line 3 in real time; the wireless communication module 6 converts the monitored information data from electrical signals to wireless signals, and then transmits the wireless signals to the remote terminal, thereby reducing the line problems that cannot be detected in real time by traditional manual inspections, making the safe operation of the transmission line more intelligent and accurate, and improving the operation safety monitoring capability of the high-voltage transmission line under severe weather conditions such as strong winds.

[0026] As a preferred embodiment of the present invention, Figure 2-4As shown, the power supply mechanism is a current transformer 4, and the high-voltage transmission line 3 passes through the current transformer 4. The power supply mechanism can use solar panels or batteries. The power generation efficiency of solar panels is affected by factors such as weather, season and geographical location, and cannot guarantee a continuous and stable energy supply. It can only be used in sunny places, and cannot provide a stable energy supply in rainy days or areas with insufficient sunlight. In addition, solar panels need to be cleaned and maintained regularly to ensure their normal operation, which will also increase their maintenance costs. Although in many scenarios, batteries are a reliable and convenient way to supply energy. However, in the use scenario of this device, the shortcomings of batteries are more prominent. First, their capacity is limited and they cannot provide enough power when the device is used for a long time; second, their lifespan is limited, and long-term use or improper use may cause battery aging or damage; third, it takes a certain amount of time to charge the battery, and there will be a window period during this period, so the purpose of real-time detection cannot be achieved. If you choose to replace the detection device, the cost will increase; fourth, the battery needs to be regularly maintained and replaced, which increases the cost of use. The advantages of this embodiment are: the current transformer 4 uses insulating material as the outer packaging, has a very high voltage resistance, can effectively avoid personal injury caused by accidents such as electric shock and electric arc, and its interior is made of high-quality materials, can withstand harsh conditions such as high temperature and high pressure, and has relatively stable performance; and it is not affected by the external environment and can operate normally in various complex electromagnetic environments; at the same time, the installation operation of the AC transformer 4 is simple and the accuracy is very high. Only basic wiring is required to achieve power conversion within a very small error range; the AC transformer 4 is small in size and light in weight, can be moved and installed at will, is very convenient, and greatly reduces the difficulty of installation and maintenance work.

The advantage of this embodiment is that the fixing sleeve is tightened on the high-voltage transmission line 3, so that the assembly shell is better fixed on the high-voltage transmission line 3. When the high-voltage transmission line 3 dances, the relative movement between the assembly shell and the high-voltage transmission line 3 is reduced, and the high-voltage transmission line 3 is effectively prevented from being damaged.

[0028] As a preferred embodiment of the present invention, Figure 1 , 5As shown, the fixing sleeve includes a flange ring 11, a connector 12 and a fixing ring 13. One end of the flange ring 11 is detachably connected to the assembly shell, and the other end of the flange ring 11 is connected to the fixing ring 13 through the connector 12. The flange ring 11 and the fixing ring 13 are structures made of metal materials, and the connector 12 is a structure made of rubber material, and the connector 12 is connected and fixed to the flange ring 11 and the fixing ring 13 through a vulcanization process. The advantage of this embodiment is that the fixing sleeve is designed to be detachable, which facilitates the disassembly and replacement of parts; the advantage of selecting rubber material for the connector 12 is that in the case of strong winds, the device will dance and rotate with the high-voltage transmission line 3, so that the high-voltage transmission line 3 is tightened. By setting the connector 12 to be a rubber material, there is a buffering effect between the fixing ring 13 and the flange ring 11, which reduces the rotation of the device. After the strong wind ends, the device can be stabilized faster and better protect the safety of the high-voltage transmission line 3.

[0029] As a preferred embodiment of the present invention, Figure 5 As shown, the fixing sleeve is evenly divided into two sub-sleeve bodies along its axis, and the two sub-sleeve bodies are buckled with each other and tightened by the clamp 14. The advantage of this embodiment is that in the actual installation process, the fixing sleeve is divided into two symmetrical parts, and the two parts can be buckled on the high-voltage transmission line 3, and then tightened by the clamp 14, avoiding the fixing sleeve from being inserted from one end of the high-voltage transmission line 3, making the installation more convenient and quick, and reducing the complexity of the installation operation.

[0030] As a preferred embodiment of the present invention, Figure 1-3As shown, the assembly shell includes an upper shell 1 and a lower shell 2, one end of the upper shell 1 is connected to the lower shell 2 by a pivoting manner, and the other end of the upper shell 1 is connected to the lower shell 2 by a steel spring 9, one end of the steel spring 9 is detachably connected to the upper shell 1, and an elastic buckle is fixedly provided on the other end of the steel spring 9 facing the side of the lower shell 2, and a clamping hole corresponding to the elastic buckle is provided on the lower shell 2, and the elastic buckle is elastically clamped in the clamping hole.

In order to facilitate the installation of the device while allowing the high-voltage transmission line 3 to pass through the assembly shell, semicircular holes are respectively provided on the end faces where the upper shell 1 and the lower shell 2 contact along the extension direction of the high-voltage transmission line 3. When the upper shell 1 and the lower shell 2 are buckled, the two semicircular holes form a complete wire hole, and this wire hole can be used for the high-voltage transmission line 3 to pass through.

[0031] As a preferred embodiment of the present invention, Figure 6 As shown, a pre-twisted wire 10 is spirally wound around the periphery of the high-voltage transmission line 3 along the extension direction of the high-voltage transmission line 3, and the assembly shell is mounted on the pre-twisted wire 10. The advantage of this embodiment is that when the high-voltage transmission line 3 is in a wind dance situation, the assembly shell of the device and the contact part of the high-voltage transmission line 3 will inevitably move relative to each other, and under the action of a long time, the high-voltage transmission line 3 may be cut. By adding the pre-twisted wire 10, the high-voltage transmission line 3 is prevented from being torn, twisted, cut, etc. due to external force. Accidental damage, such as, is effectively improved. The tensile strength and safety of the high-voltage transmission line 3 are effectively improved.

[0032] As a preferred embodiment of the present invention, Figure 1 , 3 As shown, an acceleration sensor 8 electrically connected to the power supply mechanism is detachably provided inside the assembly shell.

[0033] As a preferred embodiment of the utility model, the dancing collection frequency of the acceleration sensor 8 is not less than 30Hz, and the dancing reporting time interval is 2 to 240 minutes. The advantage of this embodiment is that: considering that real-time transmission of data will occupy a large bandwidth, the dancing collection frequency of the acceleration sensor 8 is not less than 30Hz, and the dancing reporting time interval is 2 to 240 minutes, thereby reducing the bandwidth occupied by remote communication.
