[0002] As an important facility for power transmission, transmission lines are prone to accidents when struck by lightning, causing casualties and property losses. Traditional line arresters mainly use the conductivity of metal conductors to conduct the high voltage and high current caused by lightning strikes into the earth. Although they can effectively prevent lightning strikes and ensure building safety, when there are storms or strong winds, traditional arresters are not stable enough and are easily affected by wind and deviate from the vertical direction, which not only affects the normal operation of the arrester, but may also cause safety hazards. The existing technology mainly enhances the stability of the arrester through basic reinforcement measures, such as increasing the diameter of the lightning rod, installing a support base, etc. However, these methods can only improve the stability of the arrester to a certain extent, and cannot effectively cope with the challenges in strong wind environments.

[0003] In the prior art, the arrester is hung at a hinged point on the connection point of the transmission line. Due to the external wind force, it will cause oscillation or swing, causing its longitudinal axis to deviate from the vertical line, thereby reducing the phase-to-phase and phase-to-ground distances of the transmission line to below the safety standard, increasing the risk of short circuits and failures and other technical problems.

[0004] The present invention aims to effectively enhance the wind resistance and stability of the arrester by adopting an intelligent vertical stability enhancement device. The device will automatically adjust according to the real-time wind conditions to ensure that the arrester always maintains a vertical direction, effectively improving the safety, reliability and wind resistance of the arrester, ensuring a safe distance from the transmission line, and protecting the arrester from structural damage, thereby ensuring the stable and safe operation of the power device.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0028] Example 1

[0029] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a lightning arrester vertical stability enhancement device, and the lightning arrester vertical stability enhancement device includes a lightning arrester body 100, a stabilization component 200 and a control component 300.

[0030] Specifically, the arrester body 100 is fixedly mounted on the bottom of the insulator 300, and a disconnector 400 is mounted on the top connection of the insulator 300. The disconnector 400 is connected to the arrester body 100 through a wire 500. The wire 500 is a multi-strand soft wire.

[0031] A shell 201 is fixedly connected to the bottom of the arrester body 100, and a center of mass adjuster 202 is installed inside and outside the shell 201 to keep its own center of mass and the center of mass of the arrester body 100 on the same vertical line, thereby keeping the arrester body 100 in a vertical state.

[0032] Furthermore, the control component 600 includes a microprocessor module 601 and a sensor unit 602. The sensor unit 602 can collect external environmental wind data and spatial position information of the center of mass adjustment member 202. When the arrester body 100 sways, the microprocessor module 601 will send control instructions to the center of mass adjustment member 202 in real time according to the data collected by the sensor unit 602, so that it can continuously adjust its own center of mass position to be on the same vertical line with the center of mass of the arrester body 100.

[0033] Example 2

[0034] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0035] Specifically, the center of mass adjustment member 202 includes wings 202a fixedly mounted at both ends of the housing 201, and the wings 202a are driven by a motor. When the wings 202a rotate, lift can be generated. When the arrester body 100 tilts in a certain direction, the corresponding wing 202a will adjust the angle to generate a force in the opposite direction. For example, if the arrester body 100 tilts to the left, the wing 202a on the left may adjust the angle upward to increase the lift upward and to the right, while the wing 202a on the right may adjust the angle downward to increase the force downward and to the right. The tilt of the arrester body 100 is corrected by the combined force of these two forces to restore it to a vertical direction.

[0036] Specifically, the centroid adjustment member 202 further includes a first adjustment module 202a and a second adjustment module 202b disposed inside the housing 201. The first adjustment module 202a and the second adjustment module 202b can adjust the centroid position of the centroid adjustment member 202 in the horizontal direction.

[0037] Furthermore, the first adjustment module 202a includes a first track seat 202a-1, a first drive motor 202a-2 disposed at the end of the first track seat 202a-1, a first screw rod 202a-3 connected to the output end of the first drive motor 202a-2, and a moving block 202a-4 matched with the first screw rod 202a-3. The first drive motor 202a-2 is fixed at one end of the first track seat 202a-1, and its output end is connected to the first screw rod 202a-3. When the first drive motor 202a-2 rotates, it can drive the first screw rod 202a-3. When the first screw rod 202a-3 rotates, the moving block 202a-4 matched with it will also move along the length direction of the first screw rod 202a-3.

[0038] Furthermore, the second adjustment module 202b includes a second track seat 202b-1, a second drive motor 202b-2 disposed at the end of the second track seat 202b-1, a second screw rod 202b-3 connected to the output end of the second drive motor 202b-2, and the weight block 202c matched with the second screw rod 202b-3. The second track seat 202b-1 and the first track seat 202a-1 are perpendicular to each other, one in the horizontal direction and the other in the vertical direction, and the second track seat 202b-1 is fixed on the moving block 202a-4 and can move with the moving block 202a-4. When the second drive motor 202b-2 drives the second screw rod 202b-3 to rotate, the weight block 202c on the second screw rod 202b-3 will also move accordingly.

[0039] That is to say, the weight block 202c can move laterally and longitudinally in the shell 201, so that when the lightning arrester body 100 is tilted, the weight block 202c can adjust its position in real time according to instructions, so that it is on the same vertical line with the center of mass of the lightning arrester body 100.

[0040] Further, the sensor unit 602 includes a wind sensor 602a, a position sensor 602b and an angle sensor 602c. Among them, the wind sensor 602a is installed at the bottom of the housing 201, and is used to collect wind data in the environment, the position sensor 602b is used to collect the spatial position information of the weight block 202c, and the angle sensor 602c is used to collect the tilt angle information of the arrester body 100. The information collected by the sensor unit 602 will be sent to the microprocessing module 601. After receiving the data and calculating, the microprocessing module 601 uses the mechanical formula to calculate the deflection torque and residual stress according to the wind data and the physical parameters of the arrester stabilization device and the arrester device. The control system will determine the direction and distance of the weight block 202c that needs to be adjusted based on these values. The weight block 202c is precisely moved by the first drive motor 202a-2 and the second drive motor 202b-2 to change its position, so that the overall center of mass of the device below the arrester body 100 is adjusted to be on the same vertical line as the center of mass of the arrester body 100 device, thereby counteracting wind torque and ensuring the vertical state and stable performance of the device.

[0041] Example 3

[0042] Reference Figure 5 , which is the third embodiment of the present invention, and is based on the first two embodiments. This embodiment provides a method for using a lightning arrester vertical stability enhancement device, which is applicable to the lightning arrester vertical stability enhancement device described in Embodiment 1 and Embodiment 2. The method comprises:

[0043] S1: Obtain wind force information and spatial position information of the arrester body 100 through the sensor unit 602 .

[0044] Specifically, the sensor unit 602 includes a wind sensor 602a, a position sensor 602b and an angle sensor 602c. The wind sensor 602a is installed at the bottom of the housing 201 to collect wind data in the environment, the position sensor 602b is used to collect the spatial position information of the weight block 202c, and the angle sensor 602c is used to collect the tilt angle information of the arrester body 100.

[0045] S2: The microprocessor module 601 collects wind information and spatial position information of the arrester body 100 for real-time calculation.

[0046] Specifically, the information collected by the sensor unit 602 is sent to the microprocessor module 601. After receiving the data and performing calculations, the microprocessor module 601 uses mechanical formulas to calculate the deflection torque and residual stress based on the wind data and the physical parameters of the lightning arrester stabilizer and the lightning arrester device.

[0047] S3: The microprocessor module 601 sends action instructions to the first drive motor 202a-2 and the second drive motor 202b-2 according to the calculation results, thereby controlling the position of the weight block 202c to keep the arrester body 100 vertical.

[0048] Specifically, the control system determines the direction and distance of the weight block 202c that needs to be adjusted according to these values. The weight block 202c is accurately moved by the first drive motor 202a-2 and the second drive motor 202b-2 to change its position, so that the overall center of mass of the device below the arrester body 100 is adjusted to be on the same vertical line as the center of mass of the arrester body 100 device, thereby counteracting wind torque.

[0049] On the other hand, the drone wing dynamically adjusts the angle according to the received signal. Specifically, when the arrester body 100 tilts in a certain direction, the corresponding wing 202a will adjust the angle to generate a force in the opposite direction. For example, if the arrester body 100 tilts to the left, the wing 202a on the left may adjust the angle upward to increase the upward and rightward lift, while the wing 202a on the right may adjust the angle downward to increase the downward and rightward force. The tilt of the arrester body 100 is corrected by the combined force of these two forces to restore it to a vertical direction. The entire adjustment process is dynamic, and it is constantly adjusted as the wind force changes and the state of the arrester to ensure that the arrester always remains in a vertical state.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
