Description

A pull-out interphase spacer assembly Technical Field

[0001] This utility model relates to the field of power protection technology, specifically a pull-out phase-to-phase spacer assembly. Background Technology

[0002] Spacer bars are devices installed on split conductors to fix the spacing between each split conductor, preventing conductors from whipping each other and suppressing aerodynamic vibrations and secondary span oscillations. Existing spacer bars are installed by drone hoisting. When the spacer bars fix the cable, the cable is clamped. After clamping, the power source is no longer working. At this time, because the surface protection of the cable is elastic, it will move in the opposite direction against the clamping block, resulting in insufficient clamping force on the cable.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Please refer to Figures 1, 2, and 3. A pull-out interphase spacer assembly includes a spacer body 1. Control servos 5 are connected to the left and right ends of the spacer body 1, respectively. The control servos 5 are existing technology and will not be described in detail again. The control servos 5 are used to disconnect from the spacer body 1 to achieve remote control. L-shaped connectors 2 are fixed to both ends of the spacer body 1. A fixing cover 4 is detachably connected to the upper side of the connector 2. An electric wrench 41 is fixed to the fixing cover 4. The electric wrench 41 serves as a power source, driving a threaded rod 24 to rotate, causing a moving block 22 to move upwards and cooperate with the fixing block 21 to clamp and fix the cable. A crossbar is fixed to one side of the control servo 5. The control servo 5 is fixedly connected to the fixing cover 4 via the crossbar, facilitating the use of a drone to retrieve the control servo 5 and electric wrench 41 for reuse after the control servo 5 is disconnected from the spacer body 1 and the fixing cover 4 is disconnected from the connector 2.

[0025] Please refer to Figures 2, 3, 4, 5, and 6. The lower end of the connector 2 is slidably connected to a movable block 22. A fixing block 21 is fixed to the outer side of each connector 2. The outer side of each fixing block 21 has a folded edge. This folded edge facilitates the connection of the device to the cable, increasing the probability of placing the spacer body 1 on the conductor during installation. Insulating gaskets 23 are fixed to the opposite sides of the fixing block 21 and the movable block 22. These insulating gaskets 23 provide insulation during cable clamping, preventing electrical conductivity. A threaded rod 24 is rotatably connected to the connector 2. The threaded rod 24 is driven by the movable block 22, causing the movable block 22 to move upwards to clamp the cable, ensuring its secure fixation. The inner side of the connector 2... A sliding groove 25 is provided, which guides the movable block 22. Simultaneously, the sliding groove 25 engages with the movable block 28 to prevent the fixed ring 27 and the threaded rod 24 from rotating in opposite directions. A fixed ring 27 is fixed to the threaded rod 24, and multiple arc-shaped movable blocks 28 are rotatably connected to the fixed ring 27. These movable blocks 28 are arranged in a ring, with one end rotatably connected to the fixed ring 27. The center of the fixed ring 27 is elastically connected to the fixed ring 27 via a spring. By setting the movable blocks 28 to an arc shape, it is easy for them to engage in the sliding groove 25. The electric wrench 41 is connected to the threaded rod 24, and the threaded rod 24 drives the movable block 22 to move, facilitating the clamping of the cable by the movable block 22 and the fixed block 21. The engagement of the movable block 28 with the sliding groove 25 prevents the threaded rod 24 from rotating in the opposite direction, further preventing the movable block 22 from moving downwards.

[0026] Please refer to Figure 2. Two symmetrically arranged connecting cylinders 3 are fixed to the upper end of the connector 2. Four rectangularly distributed electromagnets 42 are fixed to the lower end of the fixing cover 4. A fixing shaft 44 is slidably connected to the threaded rod 24. One end of the fixing shaft 44 is inserted into the connecting cylinder 3. A compression spring 43 is fixed to the side of each electromagnet 42 near the connecting cylinder 3. The other end of the compression spring 43 is fixed to the fixing shaft 44. The electromagnets 42, compression springs 43, and fixing shaft 44 work together to facilitate the separation of the fixing cover 4 from the connector 2 after the spacer body 1 is installed. When the fixing cover 4 and connector 2 are separated, the electromagnets 42 are energized remotely, generating magnetic force. The electromagnets 42 attract the fixing shafts 44, pulling the portion of the fixing shaft 44 inserted into the connecting cylinder 3 out of the connecting cylinder 3. At this time, the compression spring 43 is compressed. When all the fixing shafts 44 are separated, the connector 2 is separated from the fixing cover 4, facilitating the recycling and reuse of the electric wrench 41.

[0027] Please refer to Figures 2, 4, and 7. The output end of the electric wrench 41 is fixedly connected to a transmission component. The lower end of the transmission component has a hexagonal countersunk hole. The transmission component is connected to the threaded rod 24 through the hexagonal countersunk hole, which facilitates the transmission of the force generated by the electric wrench 41 to the threaded rod 24 and also facilitates the disengagement of the electric wrench 41 from the threaded rod 24. The interior of the slide groove 25 is fixed with multiple locking blocks 26 distributed from top to bottom. The left and right sides of the moving block 22 are elastically connected to locking blocks 221 through spring sheets. The locking blocks 221 engage with the locking blocks 26 to fix the moving block 22 and prevent it from sliding down. The locking blocks 221 cooperate with the slide groove 25 to guide the movement of the moving block 22 and ensure that the moving block 22 can move upward smoothly.

[0028] When using this utility model:

[0029] First, the device is launched into the air using a drone and hovered above the cable;

[0030] Then, control the drone to move so that the cable is between the fixed block 21 and the moving block 22. After completion, hover the drone and remotely control the electric wrench 41 to work by controlling the servo motor 5.

[0031] Next, the electric wrench 41 drives the threaded rod 24 to work, and the threaded rod 24 drives the moving block 22 to move upward. Through cooperation with the fixed block 21, the cable is clamped and fixed. During the fixing process, the locking block 221 and the locking block 26 are locked together to prevent the moving block 22 from sliding down. The slide groove 25 also abuts and locks against the movable block 28 to prevent the fixed ring 27 and the threaded rod 24 from rotating in opposite directions.

[0032] Finally, after the spacer body 1 is installed, the fixing cover 4 is detached from the connector 2. When the fixing cover 4 and connector 2 are detached, the remote control electromagnet 42 is energized, and the electromagnet 42 generates magnetic force. The electromagnet 42 attracts the fixing shaft 44, pulling the part of the fixing shaft 44 inserted into the connecting cylinder 3 out of the connecting cylinder 3. At this time, the compression spring 43 is compressed. After all the fixing shafts 44 are detached, the connector 2 and the fixing cover 4 are detached. After the connection between the control servo motor 5 and the spacer body 1 is released, the electric wrench 41 is retrieved by the drone for reuse.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
