[0064] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] As Figure 1 - Figure 14 shown, what the present invention provides:

[0066] A primary-secondary integrated on-column circuit breaker includes an on-column circuit breaker body 10 and a hoop 20. An installation unit 30 is assembled on the hoop 20. The hoop 20 is adapted to the utility pole and is used to fix the installation unit 30 on the utility pole. The installation unit 30 includes a cross frame 31 and a lifting component 40 assembled on the cross frame 31. The on-column circuit breaker body 10 is assembled on the lifting component 40. One end of the cross frame 31 is hinged with a telescopic support frame 32;

[0067] More specifically, a hoop 33 is rotatably connected to the clamping hoop 20 through a circular groove. The two hoops 33 are respectively connected to the cross frame 31 and the telescopic support 32, enabling the installation unit 30 to rotate the pole-mounted circuit breaker body 10. The hoop 33 is locked to the clamping hoop 20 after rotation through a locking mechanism 34 provided on its surface.

[0068] It further includes a self-rotation component 50 assembled to the bottom of the cross frame 31 through a cross bar 35, and the pole-mounted circuit breaker body 10 rotates self by cooperating with the rotation of the cross frame 31.

[0069] As shown in Figure 1 、 Figure 7 and Figure 9 The installation unit 30 further includes a translation component 60 assembled in the cross bar 35. The translation component 60 includes a sliding seat 61 slidably mounted in the cross bar 35. The tops of the two sliding seats 61 are jointly fixed with a moving plate 67, and the bottom of the moving plate 67 is in contact with the cross frame 31.

[0070] As shown in Figure 1 、 Figure 4 and Figure 5 The lifting component 40 includes a rotating seat 41 rotatably connected to the moving plate 67. A upper inclined surface seat 42 is slidably connected to the rotating seat 41. A lower inclined surface seat 43 is provided on the upper inclined surface seat 42. The pole-mounted circuit breaker body 10 is assembled on the surface of the lower inclined surface seat 43. Four guiding seats 44 are welded at the edge of the rotating seat 41. The lower inclined surface seat 43 is slidably connected to the guiding seats 44 through guiding sliders.

[0071] On both sides of the upper surface of the rotating seat 41, supporting seats 45 are welded. A screw rod 46 is threadedly connected to the supporting seats 45. One end of the screw rod 46 is rotatably connected to the upper inclined surface seat 42 through a bearing. The other ends of the two screw rods 46 are respectively inserted with a limiting slide rod 410 through a limiting chute.

[0072] A connecting shaft 47 is rotatably connected inside the upper inclined surface seat 42. The connecting shaft 47 penetrates through both ends of the upper inclined surface seat 42 and is respectively connected to one end of the two screw rods 46, enabling the two screw rods 46 to rotate together. Specifically, in order to prevent the connecting shaft 47 from hindering the movement of the lower inclined surface seat 43, a upper sunken groove corresponding to the connecting shaft 47 is provided in the middle of the lower surface of the lower inclined surface seat 43.

[0073] A first connecting frame and a second connecting frame are fixed inside the cross frame 31. A transmission shaft is rotatably connected inside the first connecting frame. One end of the transmission shaft is fixed with a universal coupling 48. One end of the universal coupling 48 is rotatably connected inside the second connecting frame.

[0074] One end of the limit slide bar 410 is fixed with a connector 49. The connector 49 is inserted into the opening at the end of the universal coupling 48. Two threaded holes are opened at the end of the connector 49, and positioning screw holes adapted to the threaded holes are opened at the end of the universal coupling 48. A positioning bolt is commonly threadedly connected in the positioning screw hole and the threaded hole, so that when the transmission shaft rotates, the screw 46 can be driven to rotate together through the universal coupling 48. Further in detail, after the positioning bolt is screwed out from the corresponding threaded hole and the positioning screw hole, it is screwed into another threaded hole on the connector 49 to prevent the positioning bolt from falling off when not in use. At this time, when the universal coupling 48 rotates, it will not drive the connector 49 to rotate together;

[0075] Specifically, during the overhaul process, when the height of the pole-mounted circuit breaker body 10 needs to be adjusted, the transmission shaft is rotated to drive the screw 46 to rotate through the universal coupling 48, and then the upper inclined seat 42 is driven to move from right to left, and then gradually drive the lower inclined seat 43 to drive the pole-mounted circuit breaker body 10 on its surface to move upward. After the overhaul is completed, it can be reset. It should be noted that before adjusting the horizontal position of the pole-mounted circuit breaker body 10, the positioning bolt needs to be screwed out and screwed into another threaded hole. In this state, the universal coupling 48 and the connector 49 are no longer connected, so that the pole-mounted circuit breaker body 10 can move horizontally smoothly. In particular, only during the height adjustment process, the positioning bolt needs to be installed in the threaded hole and the positioning screw hole in advance to ensure the connection between the universal coupling 48 and the connector 49. Similarly, when the pole-mounted circuit breaker body 10 is turned, the height can still be adjusted in this way.

[0076] As Figure 2 and Figure 3 shown, one end of the slide seat 61 is fixed with a telescopic rod 62. One end of the telescopic rod 62 is fixed with a limiting seat. The limiting seat is detachably fixed in the cross bar 35. A first spring 63 is sleeved on the outer surface of the telescopic rod 62. Further in detail, both ends of the first spring 63 are respectively connected with the limiting seat and the slide seat 61;

[0077] One side of the inner wall of the cross bar 35 away from the limiting seat is rotatably connected with a guide post 64. Two cross frames 31 are jointly rotatably connected with a shaft rod 66. One side of the slide seat 61 is fixed with a pull rope 65. One end of the pull rope 65 is turned through the guide post 64 and sequentially penetrates through the slide seat 61 and the limiting seat and then is fixed with the shaft rod 66;

[0078] More specifically, handles are fixed at both ends of the shaft rod 66. A limiting plate is fixedly sleeved on the part of the shaft rod 66 extending into the cross frame 31, which is used to limit the rope body when the shaft rod 66 winds the pulling rope 65. A positioning disk is detachably fixed on the outer wall of the cross frame 31. The positioning disk is sleeved on the shaft rod 66. A set screw is threaded through the handle at the end of the shaft rod 66. Multiple set screw holes are arranged in a circumferential array on the surface of the positioning disk. After the rotation of the shaft rod 66 stops, by tightening the set screw, the handle can be fixed on the positioning disk, so that the shaft rod 66 is fixed, and the wound pulling rope 65 will not reset itself.

[0079] Specifically, during the overhaul process, when it is necessary to move the position of the pole-mounted circuit breaker body 10, first screw out the positioning bolt, and then rotate the shaft rod 66 through the handle to wind the pulling rope 65, so as to drive the sliding seat 61 to drive the pole-mounted circuit breaker body 10 to move horizontally. When it moves to a suitable position, by tightening the set screw, the handle is fixed on the positioning disk, so that the position of the shaft rod 66 is fixed. After the overhaul is completed, first release the fixation of the handle, and then rotate the shaft rod 66 to relax the pulling rope 65, so that the sliding seat 61 is gradually pulled back under the drive of the first spring 63. After resetting, fix the handle again, and at this time the position of the pole-mounted circuit breaker body 10 is also fixed.

[0080] As Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown in

[0081] The locking mechanism 34 includes a U-shaped seat fixed on the outer wall of the connecting seat. A clamping clip 341 that fits against the outer wall of the hoop 33 is rotatably connected in the U-shaped seat through a pivot. Limiting grooves are provided on the outer walls of the hoop 33 and the clamping hoop 20.

[0082] A limiting block 342 adapted to the limiting groove is fixed on the inner wall of the clamping clip 341. A torsion spring 343 for driving the clamping clip 341 to closely fit against the hoop 33 is installed on the pivot.

[0083] Specifically, under the drive of the torsion spring 343, the clamping clip 341 will closely fit against the outer wall of the hoop 33, so that the limiting block 342 is engaged in the limiting groove, and the rotated hoop 33 is fixed on the surface of the clamping hoop 20.

[0084] As Figure 4 、 Figure 5 、 Figure 9 、Figure 10 , Figure 11 and Figure 14 As shown in Figure 11 and Figure 14 , the installation unit 30 further includes a locking release assembly 37 located at the bottom of two of the cross bars 35 assembled on the cross frame 31;

[0085] The locking release assembly 37 includes a main cross plate 371 and a secondary cross plate 372 clamped on the main cross plate 371. A plug plate 373 is inserted into the middle of the upper surface of the main cross plate 371 through a slot. Pulling rings 379 are fixed to the bottoms of the secondary cross plate 372, the plug plate 373, and the lower synchronous plate. It should be noted that the bottom of the inner wall of the slot is convex inward to support the plug plate 373, so that when the plug plate 373 moves downward, it can drive the main cross plate 371 to move downward together, but when the main cross plate 371 moves downward, it will not drive the plug plate 373 to move downward, and the slot can allow the pulling ring 379 to pass through;

[0086] Retention tubes are welded to the inner and outer walls of one of the cross bars 35 and the outer wall of the other cross bar 35. Connecting pieces are inserted into the retention tubes. The connecting pieces are evenly divided into three groups, and each group is fixed to the main cross plate 371, the secondary cross plate 372, and the plug plate 373 respectively. An installation groove is formed on one side of the connecting piece, and an inclined surface block is connected to the installation groove through a second spring. Limiting card slots adapted to the inclined surface block are formed at the top and bottom of the outer wall of the retention tube;

[0087] Specifically, in the initial state, the inclined surface block is engaged in the upper limiting card slot to keep the main cross plate 371, the secondary cross plate 372, and the plug plate 373 in position in the initial state. When the main cross plate 371, the secondary cross plate 372, and the plug plate 373 move downward, the inclined surface block is engaged in the lower limiting card slot, so that the moved main cross plate 371, the secondary cross plate 372, and the plug plate 373 are kept in position;

[0088] In further detail, moving restriction grooves are formed on both sides of the retention tube, and moving restriction members capable of sliding in the moving restriction grooves are provided on both sides of the connecting piece. When the connecting piece moves to the bottom of the moving restriction member abuts against the inner bottom wall of the moving restriction groove, at this time, the inclined surface block will move to be engaged in the lower limiting card slot, and at this time, when maintaining the pulled-down state, it will not pull the connecting piece to move downward further. On the contrary, in the initial state, the top of the moving restriction member abuts against the inner top wall of the moving restriction groove.

[0089] A first guide rope 374 is fixed on the outer wall of the clamp 341, and a guide ring is provided at the bottom of the mounting rod 36. The guide ring is provided to guide the first guide rope 374 to ensure that it moves according to a predetermined moving trajectory. Two first guide ropes 374 pass through the upper guide ring, and one end of which is fixed with an upper synchronization plate. The upper synchronization plate is fixed to the main horizontal plate 371. A guide plate is fixed on the inner wall of the telescopic support frame 32. The other two first guide ropes 374 pass through the lower guide ring and one end of which is fixed with a lower synchronization plate.

[0090] Two transverse retaining seats are fixed on the side of the second connecting frame close to the turntable, and a pin 375 compatible with the positioning screw hole and the threaded hole is inserted in the two transverse retaining seats. Two transverse limiting rings are fixed on the outer wall of the pin 375, and the two transverse limiting rings are respectively located below the two retaining seats. A third spring is sleeved on the outer surface of the pin 375, and the two ends of the third spring are respectively connected to the transverse limiting ring located above and the transverse retaining seat located below. A positioning hole is opened on the outer wall of the pin 375, and a vertical retaining The vertical retaining seat is provided with a positioning pin 376 adapted to the positioning hole. In further detail, two vertical limiting rings are fixed on the positioning pin 376. The movement range of the plug pin 375 and the positioning pin 376 is limited by the arrangement of the horizontal limiting ring and the vertical limiting ring. In particular, in order to facilitate the maintenance personnel to operate the positioning pin 376, an extension rod is provided at one end of the positioning pin 376, and a second guide rope 377 is fixed at the bottom end of the plug pin 375. The second guide rope 377 passes through one end of the cross bar 35 and is fixed to the plug plate 373.

[0091] The self-rotating assembly 50 includes a bearing seat fixed on the cross bar 35, a gear 52 is connected to the bearing seat through a vertical shaft 51, a half-toothed ring 53 meshing with the gear 52 is fixed on the outer wall of one of the hoop 20, a retainer is fixed to the bottom of the movable plate 67, a driven shaft 54 ​​is rotatably connected in the retainer, a sleeve 55 is sleeved on the driven shaft 54, the top of the sleeve 55 is fixed to the rotating seat 41, the outer surfaces of the vertical shaft 51 and the driven shaft 54 ​​are fixedly sleeved with pulleys, the two pulleys are meshed with a synchronous belt 56, the driven shaft 54 ​​and the sleeve 55 are provided with a keying groove, a keying rod 378 adapted to the keying groove is fixed on the secondary cross plate 372, so that the driven shaft 54 ​​can drive the sleeve 55 to rotate together when rotating, and the outer surface of the keying rod 378 is sleeved with a fourth spring, and the two ends of the fourth spring are respectively connected to the retainer and the secondary cross plate 372;

[0092] Preferably, the mounting unit 30 further comprises a pull rod for manipulating the pull ring 379, and the pull rod is in a "丩" shape as a whole, such as Figure 10As shown in the figure, specifically, it consists of a vertical rod and an L-shaped rod. Hooks for controlling the pull ring 379 are provided at the tops of both the vertical rod and the L-shaped rod. The L-shaped rod is slidably sleeved on the vertical rod, and after sliding, the position of the L-shaped rod can be fixed by bolts. In particular, the horizontal part of the L-shaped rod is telescopic to adapt to different horizontal distances between the lower pull ring 379 and the two upper pull rings 379;

[0093] Further in detail, by pulling the pull ring 379 on the lower synchronous plate and the pull ring 379 below the plug plate 373 through the pull rod, the pull ring 379 moves downward. At this time, the plug plate 373 drives the main cross plate 371 to move downward together, while the secondary cross plate 372 remains in place. When moving to the position where the inclined surface blocks on the plug plate 373 and the main cross plate 371 are engaged with the lower limit card slots, the positions of the plug plate 373 and the main cross plate 371 are fixed. In this state, the first guide rope 374 pulls the upper and lower groups of clamps 341 to open, releasing the restriction on the rotation of the hoop 33. And the second guide rope 377 will pull the bolt 375 out of the positioning screw hole and the threaded hole, releasing the connection between the end of the universal coupling 48 and the connector 49. At this time, continue to keep the state of pulling down the pull ring 379, and then pull the cross frame 31 and the telescopic support frame 32 through the pull rod to drive the pole-mounted circuit breaker body 10 to turn around the electric pole. During the turning process, the gear 52 rotates under the drive of the semi-tooth ring 53, and then under the cooperation of the belt pulley and the synchronous belt 56, the rotating seat 41 drives the pole-mounted circuit breaker body 10 to rotate 180°, so that the wiring direction is adjusted to the same direction as the original state. This adjustment method is applied to the situation where the wiring direction remains unchanged after the pole-mounted circuit breaker body 10 is switched to the other side;

[0094] When the wiring direction changes after the pole-mounted circuit breaker body 10 is switched to the other side, that is, the wiring direction is opposite to the original direction. In this case, the pull ring 379 on the lower synchronizing plate and the pull ring 379 under the auxiliary cross plate 372 are pulled downward by the pull rod. At this time, the auxiliary cross plate 372 drives the main cross plate 371 to move downward together, while the plug plate 373 remains in place. When the plug plate 373 remains in place, the plug pin 375 is in the positioning screw hole and the threaded hole, maintaining the connection state between the end of the universal coupling 48 and the connector 49. And when the auxiliary cross plate 372 and the main cross plate 371 move downward, similarly, the upper and lower groups of clamps 341 are pulled open by the first guide rope 374 to release the rotation restriction. At the same time, the auxiliary cross plate 372 will pull the key-in rod 378 downward to move it out of the key-in groove in the bushing 55, releasing the connection between the bushing 55 and the driven shaft 54. At this time, continue to maintain the state of pulling down the pull ring 379, and then pull the cross frame 31 and the telescopic support 32 with the pull rod to turn the pole-mounted circuit breaker body 10 around the electric pole. During the rotation process, the gear 52 will still rotate under the drive of the half-tooth ring 53, but at this time, only the driven shaft 54 will be driven to rotate under the cooperation of the pulley and the synchronous belt 56, so that the pole-mounted circuit breaker body 10 will not rotate by itself, and thus the wiring direction is changed to match the required wiring direction;

[0095] Further in detail, after the position conversion of the pole-mounted circuit breaker body 10 is completed, by pushing up the pull ring 379 on the plug plate 373 or the auxiliary cross plate 372, the inclined plane block clamped in the lower limit card slot is pushed out of the lower limit card slot, and after moving upward, it is re-clamped in the upper limit card slot, so that the positions of the main cross plate 371, the auxiliary cross plate 372 and the plug plate 373 after reset are fixed, and thus the upper clamp 341 is reset under the drive of the torsion spring 343. It should be noted that when the downward pulling state of the pull ring 379 on the lower synchronizing plate is released, the lower clamp 341 is reset under the action of the torsion spring 343, so that the hoop 33 is restricted on the hoop 20, thereby fixing the positions of the cross frame 31 and the telescopic support 32. In both operation methods, the operator only needs to stand on the ground to complete the operation, which is convenient;

[0096] In addition, it should be noted that when initially installing the pole-mounted circuit breaker body 10, the plug pin 375 needs to be inserted into the positioning screw hole and the threaded hole to ensure the connection between the connector 49 and the universal coupling 48, so as to maintain the position of the rotating seat 41 and prevent it from moving, thereby ensuring the position of the pole-mounted circuit breaker body 10;

[0097] During the maintenance process, it is necessary to first manually move the bolt 375 downward to separate it from the positioning screw hole and the threaded hole, then insert the positioning pin 376 into the positioning hole on the outer wall of the bolt 375 to fix the position of the bolt 375. Next, screw the positioning bolt into the positioning screw hole and the threaded hole, so that the connector 49 and the universal coupling 48 are fixed under the action of the positioning bolt. At the same time, the bolt 375 will not hinder the rotation during the rotation process. When the maintenance is completed, remove the positioning bolt and then reset the bolt 375.

[0098] Specifically, when the integrated primary and secondary pole-mounted circuit breaker is working / being used:

[0099] 1. Initial installation and preparation: Assemble the pole-mounted circuit breaker body 10 on the lifting assembly 40, and fix it on the utility pole through the hoop 20 and the mounting unit 30. Ensure that the bolt 375 is inserted into the positioning screw hole and the threaded hole, maintain the connection between the connector 49 and the universal coupling 48, and fix the position of the rotating seat 41;

[0100] Check whether all components are installed correctly to ensure that the circuit breaker is in an initial stable state;

[0101] 2. Height adjustment: Screw the positioning bolt into the threaded hole and the positioning screw hole. By rotating the transmission shaft, the universal coupling 48 drives the screw 46 to rotate, driving the upper inclined seat 42 to move, thereby adjusting the height of the pole-mounted circuit breaker body 10;

[0102] 3. Horizontal position adjustment: Unscrew the positioning bolt from the threaded hole and the positioning screw hole, and screw it into another threaded hole to disconnect the connection between the universal coupling 48 and the connector 49. Then, wind up the pull rope 65 by rotating the shaft rod 66 to drive the sliding seat 61 to move horizontally, thereby adjusting the horizontal position of the pole-mounted circuit breaker body 10. After adjusting to the appropriate position, tighten the locking bolt to fix the shaft rod 66 and the pull rope 65 to keep the position of the pole-mounted circuit breaker body 10 stable;

[0103] 4. Rotation adjustment (the wiring direction remains unchanged): Pull the lower synchronous plate and the pull ring 379 below the plug plate 373 through the pull rod to move the main cross plate 371 and the plug plate 373 downward, releasing the rotation restriction of the clamp 341 on the hoop 33. At the same time, the bolt 375 is removed from the positioning screw hole and the threaded hole, disconnecting the connection between the universal coupling 48 and the connector 49;

[0104] Then, pull the cross frame 31 and the telescopic support 32 through the pull rod to turn the pole-mounted circuit breaker body 10 around the utility pole. During the turning process, the gear 52 rotates under the drive of the half-tooth ring 53, and drives the rotating seat 41 to drive the pole-mounted circuit breaker body 10 to rotate 180° through the belt pulley and the synchronous belt 56;

[0105] 5. Rotation adjustment (changing the wiring direction): Pull the lower synchronizing plate and the pull ring 379 below the auxiliary cross plate 372 through the pull rod, so that the main cross plate 371 and the auxiliary cross plate 372 move downward, releasing the rotation restriction of the clamping clip 341 on the hoop 33. When the auxiliary cross plate 372 moves downward, pull the key-in rod 378 out of the key-in groove in the bushing 55, disconnecting the connection between the bushing 55 and the driven shaft 54;

[0106] Then, pull the cross frame 31 and the telescopic support frame 32 through the pull rod, so that the pole-mounted circuit breaker body 10 rotates around the utility pole. During the rotation process, the gear 52 will still rotate under the drive of the semi-tooth ring 53, but at this time only the driven shaft 54 rotates, and the bushing 55 will not rotate, so that the pole-mounted circuit breaker body 10 does not rotate by itself, and the wiring direction is changed at this time;

[0107] 6. Position reset and fixation: After completing the position conversion, push up the pull ring 379 on the insertion plate 373 or the auxiliary cross plate 372, so that the inclined surface clamping block is reinserted into the upper limit card slot, fixing the positions of the main cross plate 371, the auxiliary cross plate 372 and the insertion plate 373. The clamping clip 341 is reset under the drive of the torsion spring 343, fixing the hoop 33 on the hoop 20, and fixing the positions of the cross frame 31 and the telescopic support frame 32.

[0108] 7. Maintenance and repair: During the maintenance process, if it is necessary to adjust the position or height of the pole-mounted circuit breaker body 10, operate according to the above steps. After the maintenance is completed, ensure that all components are reset and fixed, and check whether the operating state of the circuit breaker is normal.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
