Description

Technical Field

[0001] This application relates to the technical field of primary and secondary integrated pole-mounted circuit breakers, and in particular to a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] The primary and secondary integrated pole-mounted circuit breaker is a key device for circuit protection and control in power distribution systems. It achieves an organic combination of traditional functions and intelligent features by deeply integrating primary equipment such as vacuum interrupters and circuit breaker bodies with secondary equipment such as sensors and control units.

[0003] In related technologies, a primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body and a mounting bracket. The circuit breaker body is mounted on the mounting bracket, which is mounted on the utility pole.

[0004] When a utility pole is tilted, it becomes difficult for workers to install the circuit breaker body horizontally, which in turn causes the circuit breaker body to tilt. Tilted installation can easily lead to a decrease in the alignment accuracy of the internal mechanical linkage components of the circuit breaker, changes in the cooperation relationship between components, and long-term uneven stress may cause deformation of the mechanism, accelerated wear, or jamming, affecting the reliability of the equipment and the safe and stable operation of the power grid. Summary of the Invention

[0005] In order to improve the problem that the primary and secondary integrated pole-mounted circuit breaker cannot be installed horizontally due to the tilt of the utility pole, this application provides a primary and secondary integrated pole-mounted circuit breaker.

[0006] This application provides a primary and secondary integrated pole-mounted circuit breaker, which adopts the following technical solution: A primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body and a mounting bracket. The circuit breaker body is mounted on the mounting bracket, which includes an adjusting plate and a mounting base. The mounting base is mounted on a utility pole. The adjusting plate has a rotating shaft rotatably connected to the mounting base. The rotating shaft has a locking block and a fixing sleeve. Multiple fixing blocks are slidably connected to the fixing sleeve, and the fixing blocks abut against each other circumferentially. The fixing sleeve has a fixing assembly for fixing the fixing sleeve to the mounting base. The fixing blocks have drive springs. When the locking block drives the fixing blocks to compress towards the drive spring, the locking block is positioned between two fixing blocks and clamps them. The fixing sleeve is fixed to the mounting base by the fixing assembly.

[0007] By adopting the above technical solution, when workers need to install the mounting bracket and circuit breaker body on an inclined utility pole, they first fix the mounting base to the utility pole, then rotate the adjusting plate to an appropriate angle. By inserting the fixing sleeve into the rotating shaft, the locking block is positioned between the two fixing blocks and clamped, thereby fixing the angle of the adjusting plate. Workers then fix the adjusting plate to the mounting base using the fixing components, so that the adjusting plate can be installed horizontally without being affected by the inclined utility pole. This avoids the circuit breaker body from tilting during installation, preventing the circuit breaker body from being subjected to uneven stress over a long period of time, which may cause deformation of the mechanism, increased wear, or jamming. This further improves the reliability of the equipment and the safe and stable operation of the power grid.

[0008] Optionally, the fixing component includes a fastener, the fixing sleeve has a fixing hole for inserting the fastener, and the mounting base has a mounting groove for inserting the fastener.

[0009] By adopting the above technical solution, the fixing sleeve has a fixing hole for fastener insertion, and the mounting base has a mounting groove for fastener insertion. The operator can fix the fixing sleeve to the mounting base by passing the fastener through the fixing hole and inserting it into the mounting groove, so as to prevent the adjusting plate from rotating through the shaft, and thus fix the adjusting plate at a horizontal angle, reducing the possibility of unintentional rotation of the adjusting plate.

[0010] Optionally, the circuit breaker body is provided with a positioning block, the adjusting plate is provided with a positioning groove for the positioning block to be inserted, the groove wall of the positioning groove is provided with a receiving groove, the receiving groove is provided with a positioning spring, the positioning spring is provided with an insert block, and the positioning block is provided with a groove for the insert block to be inserted; when the positioning block is inserted into the positioning groove, the positioning spring drives the insert block to be inserted into the groove, and the circuit breaker body and the adjusting plate are fixed.

[0011] By adopting the above technical solution, the staff aligns the positioning block on the circuit breaker body and inserts it into the positioning groove. The positioning spring drives the plug to insert into the groove, thereby fixing the circuit breaker body to the adjustment plate. Compared with bolt fixing, the staff can quickly install the circuit breaker body without the aid of tools, thus improving the installation efficiency of the circuit breaker body.

[0012] Optionally, the adjusting plate has a receiving groove on its surface near the utility pole. A baffle for sealing the positioning groove is slidably connected in the receiving groove. The baffle has an insertion hole communicating with the positioning groove and a fixed magnet. A sliding rod is slidably connected in the mounting base. The sliding rod is located on the moving path of the fastener inserted into the mounting groove and has a first magnet that repels the fixed magnet. When the fastener is inserted into the mounting groove, the fastener drives the sliding rod to move so that the first magnet aligns with the fixed magnet. The first magnet drives the baffle to move away from the mounting base through the fixed magnet, and the insertion hole aligns with the positioning groove.

[0013] By adopting the above technical solution, when the fastener is inserted into the mounting slot, the adjusting magnet is positioned on the moving path of the fastener insertion into the mounting slot, so that the fastener can drive the adjusting magnet to move, thereby aligning the first magnet with the fixed magnet. The first magnet can drive the baffle to disengage from the positioning slot through the fixed magnet. The staff can see that the adjusting plate and the mounting base are fixed in place by visually observing that the positioning slot is open. This ensures that the circuit breaker body is installed only after the adjusting plate is fixed, avoiding the situation where the adjusting plate is not fixed in place due to staff negligence.

[0014] Optionally, the sliding rod is provided with a second magnet that attracts the fixed magnet, and the sliding rod is provided with a return spring. The return spring is used to drive the sliding rod to move in the direction of the second magnet closer to the first magnet. When the fastener is not inserted into the mounting groove, the return spring drives the sliding rod to move so that the second magnet is aligned with the fixed magnet. The second magnet drives the baffle to move in the direction of closer to the rotating shaft by the attraction force on the fixed magnet. The baffle blocks the positioning groove.

[0015] By adopting the above technical solution, when the fastener is not inserted into the mounting slot, the sliding rod is driven by the reset spring to move along the direction of the second magnet closer to the first magnet, so that the second magnet is aligned with the fixed magnet. The second magnet can drive the baffle to move towards the rotating shaft through the attraction force of the fixed magnet, so that the baffle can block the positioning slot, thereby realizing the automatic reset of the baffle. The baffle can maintain the state of blocking the positioning slot, so as to prevent the workers from installing the circuit breaker body onto the adjustment plate before the adjustment plate and the mounting base are fixed, and further improve the stability of the circuit breaker body installation.

[0016] Optionally, the rotating shaft is provided with a limiting rod for pre-fixing the adjusting plate, the mounting base is provided with a through hole for inserting the limiting rod, the mounting base is provided with a placement groove communicating with the through hole, a pressure block for pressing the rotating shaft is slidably connected in the placement groove, the pressure block is set on the limiting rod, a pressure spring is sleeved on the limiting rod, and the pressure spring drives the pressure block to move toward the rotating shaft.

[0017] By adopting the above technical solution, the pressure block is driven by the pressure spring to move closer to the rotating shaft, so that the pressure spring can press against the rotating shaft through the pressure block to limit the rotation of the rotating shaft. By pressing against the rotating shaft, the rotating shaft can be pre-fixed at a certain angle, so that the worker can install the fixing sleeve on the rotating shaft. The worker does not need to fix the adjustment plate with one hand, which provides convenience for the worker to fix the adjustment plate.

[0018] Optionally, a rotating shaft is rotatably connected to the limiting rod, and an adjusting sleeve is provided on the rotating shaft. The adjusting sleeve includes a first plane and a second plane, and the distance from the first plane to the rotating shaft is greater than the distance from the second plane to the rotating shaft. When the first plane abuts against the surface of the mounting base, the rotating shaft can rotate. When the second plane abuts against the surface of the mounting base, the pressure block presses against the rotating shaft, and the adjusting plate achieves pre-fixation.

[0019] By adopting the above technical solution, the distance from the first plane to the rotating shaft is greater than the distance from the second plane to the rotating shaft, so that the pressure of the first plane on the pressure block is less than the pressure of the second plane on the pressure block. The operator can achieve the pre-fixation of the adjustment plate by switching the first plane or the second plane to abut against the mounting seat.

[0020] Optionally, the mounting base has a fixing ring groove for inserting and sliding the fixing sleeve. The groove wall of the fixing ring groove is provided with a fixing spring, and the fixing sleeve is fixedly connected to the movable end of the fixing spring. When the locking block is not inserted between the two fixing blocks, the fixing sleeve is still located in the fixing ring groove.

[0021] By adopting the above technical solution, a fixing ring groove is provided on the mounting base for the fixing sleeve to be inserted and slidably. The fixing sleeve is fixedly connected to the movable end of the fixing spring, so that the fixing sleeve can be slidably connected in the fixing ring groove. The staff does not need to carry the fixing sleeve separately for installation, avoiding the risk of loss of the fixing sleeve during transportation or installation. The elastic cooperation of the spring allows the fixing sleeve to maintain an appropriate range of motion before the fixing blocks are snapped together. This not only simplifies the operation steps, but also improves the smoothness and efficiency of the installation process, providing greater convenience for the staff to assemble on site.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When workers need to install the mounting bracket and circuit breaker body on a tilted utility pole, they first fix the mounting base to the pole, then rotate the adjusting plate to the appropriate angle. By inserting the fixing sleeve into the rotating shaft, the locking block is positioned between the two fixing blocks and clamped, thus fixing the angle of the adjusting plate. Workers then fix the adjusting plate to the mounting base using the fixing components, ensuring that the adjusting plate remains horizontally installed regardless of the tilted utility pole. This prevents the circuit breaker body from tilting during installation, thus preventing long-term uneven stress on the circuit breaker body that could cause deformation, accelerated wear, or jamming, further improving equipment reliability and the safe and stable operation of the power grid.

[0023] The fixed sleeve has a fixing hole for fasteners to be inserted, and the mounting base has a mounting groove for fasteners to be inserted. The operator can fix the fixed sleeve to the mounting base by passing the fastener through the fixing hole and inserting it into the mounting groove. This prevents the adjusting plate from rotating through the shaft, so that the adjusting plate can be fixed at a horizontal angle and reduces the possibility of the adjusting plate being rotated by unauthorized means.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This embodiment discloses a primary and secondary integrated pole-mounted circuit breaker. (Refer to...) Figure 1 and Figure 2 A primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body 1 and a mounting bracket 2. The circuit breaker body 1 is detachably connected to the mounting bracket 2, and the mounting bracket 2 is fixedly connected to a utility pole. The mounting bracket 2 includes an adjusting plate 3 and a mounting base 4. A rotating shaft 31 is fixedly connected to the adjusting plate 3. The mounting base 4 has a through hole 41 for the rotating shaft 31 to be inserted and rotated, and one end of the rotating shaft 31 extends out of the through hole 41. Two locking blocks 311 are fixedly connected to the surface of the rotating shaft 31 extending out of the through hole 41, and the two locking blocks 311 are located on opposite outer surfaces of the rotating shaft 31.

[0028] Reference Figure 3 A fixing sleeve 5 is detachably connected to the rotating shaft 31. The fixing sleeve 5 has a fixing groove 51 for the rotating shaft 31 to be inserted into. Multiple fixing blocks 511 are slidably connected to the groove wall of the fixing groove 51. The multiple fixing blocks 511 are arranged around the circumference of the fixing groove 51, and adjacent fixing blocks 511 abut against each other. A drive spring 512 is fixedly connected to the surface of the fixing block 51 near the bottom wall of the fixing groove 51. The other end of the drive spring 512 is fixedly connected to the bottom wall of the fixing groove 51.

[0029] Reference Figure 3 The fixing sleeve 5 is provided with a fixing component 32 for fixing the fixing sleeve 5 to the mounting base 4. The fixing component 32 includes a fastener 321, which is a bolt. A mounting plate 52 is fixedly connected to the outer surface of the fixing sleeve 5. The surface of the mounting plate 52 away from the mounting base 4 has a fixing hole 521 for inserting the fastener 321. The mounting base 4 has a mounting groove 42 for inserting the fastener 321. The operator inserts the fastener 321 through the fixing hole 521 into the mounting groove 42 to fix the fixing sleeve 5 to the mounting base 4.

[0030] Reference Figure 2 and Figure 3 After the operator rotates the adjusting plate 3 to a suitable angle, the fixing sleeve 5 is inserted into the rotating shaft 31, causing the locking block 311 to drive the corresponding fixing block 511 to move towards the bottom wall of the fixing groove 51. At this time, the locking block 311 is located between the two fixing blocks 511, and the two fixing blocks 511 abut against the surfaces of opposite sides of the locking block 311, clamping the locking block 311 to fix the rotating shaft 31 at a certain angle. The operator then inserts the fastener 321 through the fixing hole 521 into the mounting groove 42, fixing the fixing sleeve 5 onto the mounting base 4.

[0031] Reference Figure 3 and Figure 4 A positioning block 11 is fixedly connected to the surface of the circuit breaker body 1 near the adjusting plate 3. Multiple positioning blocks 11 are arranged along the four corners of the circuit breaker body 1. The adjusting plate 3 has multiple positioning slots 33, each for a corresponding positioning block 11 to be inserted into. A receiving slot 331 is formed on the slot wall of the positioning slot 33 away from the mounting base 4. A positioning spring 332 is fixedly connected to the bottom wall of the receiving slot 331, and an insertion block 333 is fixedly connected to the positioning spring 332. The positioning block 11 has a groove 111 for the insertion block 333 to be inserted into. When the positioning block 11 is inserted into the positioning slot 33, the positioning spring 332 drives the insertion block 333 to insert into the groove 111, thereby fixing the circuit breaker body 1 and the adjusting plate 3.

[0032] Reference Figure 3 and Figure 4 A receiving groove 34 is formed on the surface of the adjusting plate 3 near the mounting base 4. The receiving groove 34 communicates with the positioning groove 33. A baffle 35 for sealing the positioning groove 33 is slidably connected in the receiving groove 331. An insertion hole 351 communicating with the positioning groove 33 is formed on the surface of the baffle 35 away from the ground. Multiple insertion holes 351 are provided, and multiple insertion holes 351 correspond one-to-one with multiple positioning grooves 33. A return spring 421 is fixedly connected to the bottom wall of the mounting groove 42. A sliding rod 422 is fixedly connected to the end face of the return spring 421 away from the bottom wall of the mounting groove 42. The return spring 421 is used to drive the sliding rod 422 to move away from the bottom wall of the mounting groove 42, and the sliding rod 422 is located on the movement path of the fastener 321 inserted into the mounting groove 42.

[0033] Reference Figure 3 A first magnet 423 and a second magnet 424 are fixedly connected to the surface of the sliding rod 422 near the adjusting plate 3. The second magnet 424 is fixedly connected to the surface of the first magnet 423 away from the fixing sleeve 5. A fixing magnet 352 is fixedly connected to the surface of the baffle 35 near the mounting base 4. The fixing magnet 352 repels the first magnet 423 and attracts the second magnet 424.

[0034] Reference Figure 3 and Figure 4When the fastener 321 is inserted into the mounting slot 42, the fastener 321 drives the first magnet 423 to move closer to the second magnet 424, aligning the first magnet 423 with the fixed magnet 352. The repulsive force of the first magnet 423 on the fixed magnet 352 drives the baffle 35 to move away from the mounting base 4, thus disengaging the baffle 35 from the positioning slot 33. This allows the operator to install the circuit breaker body 1 onto the adjusting plate 3 while ensuring the adjusting plate 3 is properly secured. When the fastener 321 is not inserted into the mounting slot 42, the return spring 421 drives the sliding rod 422 to move along the second magnet 424 closer to the first magnet 423, aligning the first magnet 423 with the fixed magnet 352. The first magnet 423, through its attraction to the fixed magnet 352, drives the baffle 35 to move closer to the rotating shaft 31, thus blocking the positioning slot 33.

[0035] Reference Figure 3 and Figure 5 The outer surface of the rotating shaft 31 is provided with a limiting rod 36 for fixing the adjusting plate 3. The mounting base 4 has a through hole 43 for inserting the limiting rod 36. The mounting base 4 also has a placement groove 431 communicating with the through hole 43. A pressure block 432 for pressing the rotating shaft 31 is slidably connected within the placement groove 431. The pressure block 432 is fixedly connected to the end face of the limiting rod 36 near the rotating shaft 31. A pressure spring 361 is fitted on the outer surface of the rod 36. The two ends of the pressure spring 361 abut against the pressure block 432 and the groove wall of the placement groove 431 away from the rotating shaft 31, respectively. The pressure spring 361 can drive the pressure block 432 to move towards the rotating shaft 31.

[0036] Reference Figure 5 A rotating shaft 362 is rotatably connected to the end face of the limiting rod 36 away from the rotating shaft 31, and an adjusting sleeve 37 is fixedly connected to the rotating shaft 362. The adjusting sleeve 37 is configured as a cuboid and includes a first plane 371 and a second plane 372. The first plane 371 is perpendicular to the second plane 372, and the distance from the first plane 371 to the rotating shaft 362 is greater than the distance from the second plane 372 to the rotating shaft 362.

[0037] Reference Figure 5 When the first plane 371 abuts against the surface of the mounting base 4, the operator can overcome a small force to rotate the adjusting plate 3 until the operator rotates the adjusting plate 3 to a suitable angle. Then the operator rotates the adjusting sleeve 37 so that the second plane 372 abuts against the surface of the mounting base 4, and the pressure block 432 can press against the rotating shaft 31, thus achieving pre-fixation of the adjusting plate 3.

[0038] Reference Figure 2 and Figure 5The mounting base 4 has a fixing ring groove 44 for inserting the fixing sleeve 5. A fixing spring 441 is provided on the bottom wall of the fixing ring groove 44. The fixing sleeve 5 is fixedly connected to the movable end of the fixing spring 441 and slidably connected in the fixing ring groove 44. When the locking block 311 is not inserted between the two fixing blocks 511, the fixing sleeve 5 is still located in the fixing ring groove 44, so that the fixing sleeve 5 can be connected to the mounting base 4, eliminating the cumbersome step of workers having to carry and install the fixing sleeve 5 separately.

[0039] The implementation principle of the primary and secondary integrated pole-mounted circuit breaker in this application embodiment is as follows: When the worker needs to install the circuit breaker body 1 on an inclined utility pole, the worker first fixes the mounting base 4 on the utility pole, then rotates the adjusting plate 3 to an appropriate angle, and then rotates the adjusting sleeve 37 so that its second plane 372 abuts against the surface of the mounting base 4. At this time, the pressure block 432 can press against the rotating shaft 31 to achieve a certain angle of pre-fixation of the adjusting plate 3. The worker inserts the fixing sleeve 5 into the rotating shaft 31, so that the locking block 311 drives the corresponding fixing block 511 to move towards the bottom wall of the fixing groove 51. At this time, the locking block 311 is located between the two fixing blocks 511, and the two fixing blocks 511 abut against the locking block 31. On the opposite sides of the surface, the worker inserts the fastener 321 through the fixing hole 521 into the mounting groove 42, so that the fixing sleeve 5 is fixed on the mounting base 4. At this time, the fastener 321 drives the sliding rod 422 to move so that the first magnet 423 is aligned with the fixing magnet 352. The first magnet 423 drives the baffle 35 to move away from the mounting base 4 so that the insertion hole 351 is aligned with the positioning groove 33. The worker can then install the circuit breaker body 1 onto the adjustment plate 3 while ensuring that the adjustment plate 3 is fixed in place. The worker inserts the positioning block 11 into the positioning groove 33 and drives the insertion block 333 into the groove 111 through the positioning spring 332 to achieve the fixation between the circuit breaker body 1 and the adjustment plate 3.

When the fastener (321) is not inserted into the mounting slot (42), the return spring (421) drives the sliding rod (422) to move so that the second magnet (424) is aligned with the fixed magnet (352). The second magnet (424) drives the baffle (35) to move towards the direction of the rotating shaft (31) by the attraction force on the fixed magnet (352). The baffle (35) blocks the positioning slot (33).

6. The primary and secondary integrated pole-mounted circuit breaker according to claim 1, characterized in that: The rotating shaft (31) is provided with a limiting rod (36) for pre-fixing the adjusting plate (3). The mounting base (4) is provided with a through hole (43) for inserting the limiting rod (36). The mounting base (4) is provided with a placement groove (431) communicating with the through hole (43). A pressure block (432) for pressing the rotating shaft (31) is slidably connected in the placement groove (431). The pressure block (432) is set on the limiting rod (36). A pressure spring (361) is sleeved on the limiting rod (36). The pressure spring (361) drives the pressure block (432) to move toward the rotating shaft (31).

7. A primary and secondary integrated pole-mounted circuit breaker according to claim 6, characterized in that: The limiting rod (36) is rotatably connected to a rotating shaft (362), and the rotating shaft (362) is provided with an adjusting sleeve (37). The adjusting sleeve (37) includes a first plane (371) and a second plane (372). The distance from the first plane (371) to the rotating shaft (362) is greater than the distance from the second plane (372) to the rotating shaft (362). When the first plane (371) abuts against the surface of the mounting base (4), the rotating shaft (31) can rotate. When the second plane (372) abuts against the surface of the mounting base (4), the pressure block (432) presses against the rotating shaft (31), and the adjusting plate (3) achieves pre-fixation.

8. A primary and secondary integrated pole-mounted circuit breaker according to claim 1, characterized in that: The mounting base (4) has a fixing ring groove (44) for inserting and sliding the fixing sleeve (5). The fixing ring groove (44) has a fixing spring (441) on its groove wall. The fixing sleeve (5) is fixedly connected to the movable end of the fixing spring (441). When the locking block (311) is not inserted between the two fixing blocks (511), the fixing sleeve (5) is still located in the fixing ring groove (44).
