Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, specifically a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] The integrated primary and secondary pole-mounted circuit breaker is a key piece of equipment in modern power distribution networks. Its installation quality directly affects the reliability and safety of power grid operation. When installing it, it is necessary to prepare hoisting equipment (such as cranes), high-altitude work tools, torque wrenches, levels and other professional tools.

[0003] After the pole-mounted circuit breaker is hoisted onto the bracket, the lifting device and the circuit breaker are removed, and then the circuit breaker is fixed with bolts. During this process, due to the removal of the lifting device, it is difficult to align the threaded holes of the circuit breaker. At the same time, there is a safety risk before the circuit breaker is tightened with bolts. Therefore, we propose a primary and secondary integrated pole-mounted circuit breaker. Utility Model Content

[0004] The purpose of this utility model is to provide a primary and secondary integrated pole-mounted circuit breaker to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a primary and secondary integrated pole-mounted circuit breaker, comprising a circuit breaker body, an installation assembly for quick installation provided at the bottom of the circuit breaker body, the installation assembly comprising a base plate, a slide table slidably connected to the bottom of the base plate, a limit frame fixedly connected to the top edge of the slide table, a connector for fastening the base plate and the slide table by bolts fixedly connected to one side of the base plate, a snap-fit ​​assembly for temporary fixing provided on one side of the limit frame, the snap-fit ​​assembly comprising a slot, the slot being opened on one side of the base plate, a sliding groove being opened on one side of the limit frame, a snap-fit ​​block slidably connected inside the sliding groove to snap into the slot, a spring for snap-fit ​​block reset fixedly connected to the bottom of the snap-fit ​​block, and a pull rod fixedly connected to one side of the snap-fit ​​block.

[0006] Preferably, a placement groove is provided on the top side of the limiting frame, the placement groove being used to avoid part of the bottom of the base plate so that it overlaps with the top of the slide table to provide support.

[0007] Preferably, the connector has a through hole for the semi-threaded bolt to pass through, and the slide has a threaded hole for the threaded end of the semi-threaded bolt to be threadedly connected.

[0008] Preferably, a bracket is fixedly connected to the bottom of the slide table, and a first angle iron is fixedly connected to one side of the bracket by a thread, and a first clamp for fixing to the utility pole is fixedly connected to one side of the first angle iron by a nut.

[0009] Preferably, the bottom of the bracket is fixedly connected to a diagonal brace, the other end of the diagonal brace is fixedly connected to a second angle iron, and one side of the second angle iron is fixedly connected to a second clamp by a nut.

[0010] Preferably, the circuit breaker body is limited by the limiting frame through the base plate and slides along the top of the slide table until the locking block engages with the locking slot to form a temporary fixation.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The circuit breaker body is quickly positioned using a limiting frame, base plate, and slide table. This ensures that the threaded holes align with the through holes after the circuit breaker body is moved to the installation position, facilitating bolt fixing. At the same time, the limiting frame limits the base plate, allowing for effective fixing with only two bolts, thus reducing the number of bolts required and improving installation efficiency.

[0012] The slots and blocks allow the base plate and circuit breaker body to be moved to the installation position and temporarily fixed, ensuring the stability of the circuit breaker body after the lifting equipment is removed, thus improving safety. Furthermore, during subsequent maintenance and disassembly operations, after the bolts are removed, the slots and blocks act as a safety measure for the circuit breaker body, preventing the bracket from tilting and the circuit breaker body from falling off if the bracket, first clamp, or second clamp becomes loose. This facilitates subsequent maintenance work and improves operational safety. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution: such as Figures 1-4 The illustrated primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body 1. A mounting assembly for quick installation is provided at the bottom of the circuit breaker body 1. The mounting assembly includes a base plate 2, a slide table 5 slidably connected to the bottom of the base plate 2, and a limit frame 6 fixedly connected to the top edge of the slide table 5. A connector 4, which secures the base plate 2 and the slide table 5 with bolts, is fixedly connected to one side of the base plate 2. A snap-fit ​​assembly for temporary fixing is provided on one side of the limit frame 6. The snap-fit ​​assembly includes a slot 3, which is formed on one side of the base plate 2. A slide table 6 is formed on one side of the limit frame 6. The groove 8 has a sliding connection inside which a locking block 9 engages with the locking groove 3. A spring 10 for resetting the locking block 9 is fixedly connected to the bottom of the locking block 9. A pull rod 11 is fixedly connected to one side of the locking block 9. During installation, the bracket 19 and the slide table 5 are first installed on the utility pole using the first clamp 13, the second clamp 16, the first angle iron 12, the second angle iron 15, and the diagonal brace 14. Then, the circuit breaker body 1 is hoisted using hoisting equipment. When the circuit breaker body 1 is hoisted to a suitable position, personnel assist in assembling the sides of the bottom plate 2 of the circuit breaker body 1. The circuit breaker body 1 is then pushed onto the slide table 5, which is avoided by the placement groove 7. The base plate 2 slides along the top of the slide table 5, and is limited by the limiting frame 6. After pushing a certain distance, the pull rod 11 is pulled downwards, causing the pull rod 11 to overcome the spring 10 and move the locking block 9 downwards. As the base plate 2 moves, when it passes the position of the slide groove 8, the pull rod 11 is released, causing the locking block 9 to be pushed upwards under the force of the spring 10, so that the top of the locking block 9 abuts against the bottom of the base plate 2. As the base plate 2 continues to move, when the locking groove 3 on the base plate 2 moves into the slide groove... When in position 8, the locking block 9 is pushed upward under the force of the spring 10, so that the locking groove 3 and the locking block 9 are engaged. At this time, the sliding table 5 and the base plate 2 move to their limit, and the locking groove 3 and the locking block 9 form a temporary fixation for the circuit breaker body 1. The strength of the temporary fixation can withstand the self-weight of the circuit breaker body 1, ensuring the stability of the equipment after the lifting device is removed. At this time, the connection between the lifting device and the circuit breaker body 1 can be released, and personnel can thread the half-threaded bolt through the through hole 17 and the threaded hole 18 to connect the circuit breaker body 1 to the bracket 19 through the base plate 2.

[0017] like Figures 1-2As shown, a placement groove 7 is provided on the top side of the limiting frame 6. The placement groove 7 is used to avoid part of the bottom of the base plate 2 so that it overlaps with the top of the slide table 5 to provide support.

[0018] like Figures 1-4 As shown, the connector 4 has a through hole 17 for a semi-threaded bolt to pass through, and the slide 5 has a threaded hole 18 for threaded connection of the threaded end of the semi-threaded bolt. The limiting frame 6, the base plate 2, and the slide 5 quickly position the circuit breaker body 1, ensuring that the threaded hole 18 aligns with the through hole 17 after the circuit breaker body 1 is moved to the installation position, facilitating bolt fixing. Simultaneously, the limiting frame 6 limits the base plate 2, allowing for effective fixing with only two bolts, reducing the number of bolts required and improving installation efficiency. Through the slot 3 and the locking block 9, the base plate 2 and the circuit breaker body 1 are moved to the installation position and temporarily fixed by the slot 3 and the locking block 9. This ensures the stability of the circuit breaker body 1 after the lifting equipment is removed, thereby improving safety. At the same time, during subsequent maintenance and disassembly operations, after the bolts are removed, the locking block 9 and the slot 3 act as a safety device for the circuit breaker body 1, preventing the bracket 19 from tilting and causing the circuit breaker body 1 to fall off if the bracket 19, the first clamp 13 and the second clamp 16 become loose. This facilitates subsequent maintenance work and improves operational safety.

[0019] like Figures 1-3 As shown, a bracket 19 is fixedly connected to the bottom of the slide table 5. A first angle iron 12 is fixedly connected to one side of the bracket 19 by a thread. A first clamp 13 for fixing to the utility pole is fixedly connected to one side of the first angle iron 12 by a nut.

[0020] like Figures 1-4 As shown, a diagonal brace 14 is fixedly connected to the bottom of the bracket 19, and a second angle iron 15 is fixedly connected to the other end of the diagonal brace 14. A second clamp 16 is fixedly connected to one side of the second angle iron 15 by a nut.

[0021] like Figures 1-3 As shown, the circuit breaker body 1 is limited by the limiting frame 6 through the base plate 2 and slides along the top of the slide table 5 until the card block 9 and the card slot 3 are engaged to form a temporary fixation.

[0022] Working principle: During installation, the bracket 19 and slide 5 are first installed on the utility pole using the first clamp 13, the second clamp 16, the first angle iron 12, the second angle iron 15, and the diagonal brace 14. Then, the circuit breaker body 1 is hoisted using hoisting equipment. When the circuit breaker body 1 is hoisted to a suitable position, personnel assist in placing the bottom plate 2 of the circuit breaker body 1 onto the slide 5, which is cleared by the placement groove 7. The circuit breaker body 1 is then pushed, causing the bottom plate 2 to slide along the top of the slide 5, and the limiting frame 6 limits the bottom plate 2. After pushing a certain distance, the pull rod 11 is pulled downwards, causing the pull rod 11 to overcome the spring 10 and move the locking block 9 downwards. As the bottom plate 2 moves, when the bottom plate 2 passes... After the slide rail 8 is in position, release the pull rod 11, so that the locking block 9 is pushed upward under the force of the spring 10, so that the top of the locking block 9 abuts against the bottom of the base plate 2. As the base plate 2 continues to move, when the locking groove 3 on the base plate 2 moves to the position of the slide rail 8, the locking block 9 is pushed upward under the force of the spring 10, so that the locking groove 3 and the locking block 9 form a locking engagement. At this time, the slide table 5 and the base plate 2 move to their limit, and the locking groove 3 and the locking block 9 form a temporary fixation for the circuit breaker body 1. At this time, the connection between the lifting device and the circuit breaker body 1 can be released, and personnel can thread the half-threaded bolt through the through hole 17 and the threaded hole 18 to connect the circuit breaker body 1 to the bracket 19 through the base plate 2.
