Description

Technical Field

[0001] The present invention relates to the technical field of spacer dampers, and particularly to a multi-split spacer damper with adjustable split number. Background Art

[0002] In power transmission lines, as an important component of the transmission line, the spacer damper is used to maintain the distance between the sub-conductors of the multi-split conductor, prevent the conductors from whipping and twisting each other due to factors such as wind force and vibration, and thus ensure the safe and stable operation of the transmission line.

[0003] Traditional spacer dampers have many limitations. On the one hand, their split number is usually fixed, lacking flexibility when facing different transmission line layouts and different requirements for split conductors. For example, in some complex terrains or special transmission projects, it may be necessary to flexibly adjust the number of split conductors according to the actual line direction and conductor distribution to optimize the transmission efficiency and stability, but the existing spacer dampers with fixed split numbers cannot meet this requirement.

[0004] On the other hand, when facing the changing natural environment, especially the uncertainty of the wind direction, traditional spacer dampers are difficult to make adaptive adjustments. When strong wind strikes and the wind direction is inconsistent with the conductor arrangement direction, the conductors will be subjected to uneven wind forces, easily resulting in large swings or even twists, leading to conductor wear and fatigue, and may cause line failures in severe cases. However, traditional spacer dampers cannot automatically adjust their own structures according to the wind direction to reduce the adverse effects of wind force on the conductors, greatly increasing the maintenance cost and safety risk of the transmission line.

[0005] In summary, developing a spacer damper that can flexibly adjust the split number and at the same time automatically adjust according to the wind direction change has important practical significance for improving the reliability of the transmission line, reducing the maintenance cost, and adapting to the complex and changeable transmission environment. The multi-split spacer damper with adjustable split number of the present invention is developed based on this background. Summary of the Invention

[0006] In order to solve the problems that the split number of traditional spacer dampers is fixed and cannot be automatically adjusted according to the wind direction, resulting in difficulty in adapting to complex transmission line layouts and changing natural environments, prone to line failures and increased maintenance costs, the object of the present invention is to provide a multi-split spacer damper with adjustable split number.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A multi-split spacer with adjustable split number, including an inner gear ring, on which several positioning members arranged in a circular array are meshed. The end of the positioning member is sleeved with a rectangular shell. Inside the inner gear ring, a positioning ring for positioning the rectangular shell is installed. Inside the positioning ring, a wind direction monitoring component is installed. The end of the rectangular shell is rotatably connected to a connecting shaft, and the end of the connecting shaft is fixedly connected to a spacer. The end of the spacer is rotatably installed with a wire clamp.

[0008] Preferably, the positioning member includes a rectangular block, on which a groove is formed. The inner wall on one side of the groove fits with the outer wall of the inner gear ring, and the inner wall on the other side is provided with teeth meshing with the inner gear ring; on one side of the rectangular block located in the groove, a rectangular plate is hinged to cover the inner gear ring in the groove; after the rectangular block and the rectangular plate are covered, the outer walls of their ends jointly slide and are sleeved on the inner wall of the rectangular shell, and their ends are blocked against the bottom of the rectangular shell.

[0009] Preferably, two symmetrically arranged strip plates are fixedly connected to the port of the rectangular shell. Pin holes are formed in the two strip plates, and pins are installed in the pin holes; the outer wall of the pin is pressed against the inner wall of the positioning ring.

[0010] Preferably, a micro-motor is installed in the rectangular shell, and the output end of the micro-motor is axially connected to the end of the connecting shaft to adjust the direction of the spacer to adapt to the wind direction.

[0011] Preferably, the wind direction monitoring component includes a connecting plate fixedly connected to the inner wall of the positioning ring. A strip hole is formed in the connecting plate. The inner wall at the center of the strip hole is rotatably installed with a movable block through a pin shaft, and the axis of the pin shaft, the axes of the inner gear ring and the positioning ring coincide; a counterweight block is fixedly connected to the bottom of the movable block, and a wind direction plate is axially connected at the top. An angle sensor is installed in the movable block, and the monitoring end of the angle sensor is connected to the connecting shaft at the bottom of the wind direction plate to monitor the rotation angle of the wind direction plate.

[0024] The present invention provides a technical solution: a multi-split spacer with adjustable split number, including an inner gear ring 1. The inner gear ring 1 is in a ring structure, and a plurality of positioning members 2 are arranged in a circular array on its outer wall, and the positioning members 2 are fixed at different positions through their meshing. The end of the positioning member 2 is matched with a rectangular shell 3. Specifically, the outer walls of the ends of the positioning member 2 are jointly sleeved on the inner wall of the rectangular shell 3 in a sliding manner, and the ends are in butt joint with the bottom of the rectangular shell 3, so as to ensure the stable connection between the positioning member 2 and the rectangular shell 3.

[0025] A positioning ring 4 is installed inside the inner gear ring 1, and the positioning ring 4 is used to further position the rectangular shell 3. At the port of the rectangular shell 3, two symmetrically arranged strip plates 301 are fixedly connected. Pin holes are formed in the strip plates 301, and a pin 302 is installed in the pin holes, and the outer wall of the pin 302 is in tight contact with the inner wall of the positioning ring 4, so as to realize the relative positioning between the rectangular shell 3 and the positioning ring 4.

[0026] The positioning member 2 is composed of a rectangular block 201, and a groove 202 is formed in the rectangular block 201. The inner wall on one side of the groove 202 is in conformity with the outer wall shape of the inner gear ring 1, and the inner wall on the other side is provided with teeth meshing with the inner gear ring 1.

[0027] A rectangular plate 203 is hinged on one side of the rectangular block 201 where the groove 202 is located. When the rectangular plate 203 rotates to a state of covering the rectangular block 201, the inner gear ring 1 can be covered in the groove 202, preventing the meshing between the inner gear ring 1 and the positioning member 2 from loosening during use and ensuring the stability of the connection between the positioning member 2 and the inner gear ring 1.

[0028] The meshing positioning of the positioning member 2 and the inner gear ring 1 combined with the detachable property of the positioning member 2 can adjust the position of the positioning member 2 on the inner gear ring 1 according to actual needs, and further change the split number of the spacer.

[0029] The wind direction monitoring component 5 is installed inside the positioning ring 4. Its main structure includes a connecting plate 501 fixedly connected to the inner wall of the positioning ring 4, and a strip hole 502 is formed in the connecting plate 501. An active block 503 is rotatably installed on the inner wall at the center of the strip hole 502 through a pin shaft, and the axis of the pin shaft, the axis of the inner gear ring 1 and the axis of the positioning ring 4 coincide, ensuring the stability and accuracy of the rotation of the active block 503.

[0030] A counterweight block 504 is fixedly connected to the bottom of the active block 503, and the counterweight block 504 can keep the active block 503 balanced during rotation and reduce the influence of external interference factors. A wind direction plate 505 is axially connected to the top of the active block 503, and the wind direction plate 505 can rotate with the change of the wind direction. At the same time, an angle sensor is installed in the active block 503, and the monitoring end of the angle sensor is connected to the connecting shaft at the bottom of the wind direction plate 505. Through the angle sensor, the rotation angle of the wind direction plate 505 can be monitored in real time, and then the wind direction information can be obtained.

[0031] A micro-motor is installed in the rectangular housing 3, and the output end of the micro-motor is axially connected to the end of the connecting shaft 6. A spacer bar 7 is fixedly connected to the end of the connecting shaft 6. When the wind direction monitoring component 5 monitors a change in the wind direction, the angle sensor transmits a signal to the control system, and the control system controls the micro-motor to operate. The micro-motor drives the connecting shaft 6 to rotate, thereby realizing the adjustment of the direction of the spacer bar 7 so that it can adapt to the change in the wind direction and reduce the influence of the wind on the wire.

[0032] The end of the spacer bar 7 is rotatably installed with a wire clamp 8, and the wire clamp 8 is used for clamping the wire. During the actual installation process, the wire is placed at the clamping part of the wire clamp 8, and through the fastening action of the wire clamp 8, the wire is stably connected to the spacer bar 7, thereby realizing the support and spacing functions for the wire.

[0033] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
