Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and more specifically, to an installation structure for a pole-mounted circuit breaker. Background Technology

[0002] Pole-mounted circuit breakers play a crucial role in power distribution networks, effectively controlling and protecting the lines to ensure the reliability and security of power supply. With the development of smart grids, integrated primary and secondary pole-mounted circuit breakers are gradually becoming key equipment in distribution networks. They integrate traditional primary equipment (such as the circuit breaker itself) and secondary equipment (such as protection, measurement, and control units), enabling more precise monitoring and control of the distribution network.

[0003] For example, existing pole-mounted circuit breakers may malfunction during use. Direct maintenance on the installation structure is not convenient, disassembly is time-consuming, and it is not easy to quickly remove the circuit breaker body. Moreover, the installation structure of the pole-mounted circuit breaker is relatively fixed during installation, making it difficult to adjust the position of the pole-mounted circuit breaker. Therefore, it is necessary to be able to flexibly adjust the installation position of the pole-mounted circuit breaker and quickly disassemble and install it. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a solution that overcomes or at least partially solves the above technical problems.

[0005] This utility model provides an installation structure for a pole-mounted circuit breaker, including a mounting plate. A clamping installation mechanism is installed on one side of the mounting plate, and a support plate is fixed to the top of the other side of the mounting plate. A reinforcing rod is fixed between the bottom of the support plate and the bottom of the side of the mounting plate. An installation box containing electrical control components is installed at the top of the support plate. Heat dissipation holes are evenly opened at the bottom of the installation box. The circuit breaker body is fixedly installed at the top of the installation box. A snap-fit ​​installation mechanism is provided between the bottom of the installation box and the bottom of the support plate. The snap-fit ​​mounting mechanism includes drainage holes evenly spaced on the surface of the support plate, mounting rods fixed at the four corners of the bottom of the mounting box and sliding through the drainage holes, and snap-fit ​​blocks elastically mounted on the surface of the mounting rods and snapped onto the bottom of the support plate.

[0006] In a preferred embodiment, the mounting plate is vertically arranged, the support plate is horizontally arranged, and support strips are evenly fixed at its top, with the support strips being staggered from the drainage holes.

[0007] In a preferred embodiment, the top of the support bar has a placement groove, the bottom of the mounting box is installed inside the placement groove and is horizontally positioned, with its bottom end suspended between the top of the support plate and the top of the support bar.

[0008] In a preferred embodiment, the mounting rod is vertically arranged, and recesses for mounting the snap-fit ​​blocks are formed on both sides of its surface. A through hole is formed in the middle of the inner end of the recess. The recess is a rectangular groove structure and is horizontally arranged.

[0009] In a preferred embodiment, the snap-fit ​​block is slidably snapped into place inside the groove, and a spring is connected between the two snap-fit ​​blocks, the spring sliding through the through hole.

[0010] In a preferred embodiment, the clamping and mounting mechanism includes a sliding groove formed on the outer side of the mounting plate, a sliding block slidably mounted inside the sliding groove, a clamping plate fixed to the outer side of the sliding block, and a clamping groove formed on the inner side of the clamping plate.

[0011] In a preferred embodiment, both the sliding groove and the sliding block have T-shaped cross-sections and are horizontally arranged. The clamping plate is a rectangular plate structure and is vertically slidably installed on the outside of the mounting plate. The clamping groove is a V-shaped groove structure.

[0012] In a preferred embodiment, the sliding block has a threaded hole in the middle, the sliding groove has rotating holes at both ends, a threaded rod is rotatably installed inside the sliding groove, the threaded rod is rotatably threaded to the threaded hole, its two ends protrude out of the rotating hole, and nuts are connected to the two end surfaces located outside the rotating hole, and rotating bars are fixed at both ends of the threaded rod.

[0013] The targeted solution provided by this utility model has the following beneficial effects: 1. A support plate is fixed to the side of the mounting plate, and support bars are evenly fixed to the top of the support plate. Thus, the main body of the circuit breaker is fixedly installed on the top of the mounting box, and the mounting box is installed on the top of the support plate through the support bars and the placement groove. The bottom end is suspended, which facilitates ventilation and heat dissipation of the bottom end of the mounting box through the heat dissipation holes. The drainage holes can quickly drain the water accumulated on the top of the support plate, avoiding water immersion at the bottom end of the mounting box and affecting the safe use of the pole-mounted circuit breaker.

[0014] 2. The mounting box is installed on the top of the support plate. The mounting rod passes through the drain hole, the snap-fit ​​block retracts into the groove, and compresses the spring. After the groove moves to the bottom of the support plate, the two ends of the spring spring outward to push the snap-fit ​​block out of the groove, so that the snap-fit ​​block snaps into place at the bottom of the support plate, and the mounting rod and the support plate are snapped together. This facilitates the quick disassembly and installation of the mounting box and the circuit breaker body, and makes it easy to remove the upper circuit breaker of the lower column for maintenance.

[0015] 3. The sliding block and clamping plate are slidably installed on the outside of the mounting plate through the sliding groove. Therefore, when installing the pole-mounted circuit breaker, the rotating bar and threaded rod are rotated to drive the sliding block to move left and right inside the sliding groove through the threaded hole, thereby adjusting the position of the two clamping plates and the distance between them. This makes it easier to fasten the mounting plate to the external structure through the clamping groove. In this way, it is easy to flexibly adjust the position of the mounting plate and the installation position of the pole-mounted circuit breaker. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example Reference Figure 1-7 This utility model provides a technical solution: an installation structure for a pole-mounted circuit breaker, including a mounting plate 1, a clamping installation mechanism installed on one side of the mounting plate 1, a support plate 6 fixed to the top of the other side of the mounting plate 1, a reinforcing rod 7 fixed between the bottom end of the support plate 6 and the bottom end of the side of the mounting plate 1, an installation box 2 containing electrical control components installed at the top of the support plate 6, heat dissipation holes 18 evenly opened at the bottom end of the installation box 2, a circuit breaker body 3 fixedly installed at the top of the installation box 2, and a snap-fit ​​installation mechanism provided between the bottom end of the installation box 2 and the bottom end of the support plate 6.

[0023] In a preferred embodiment, the mounting plate 1 is vertically positioned, the support plate 6 is horizontally positioned, and support bars 5 are uniformly fixed to its top. The support bars 5 are staggered with the drainage holes 15.

[0024] In a preferred embodiment, the top of the support bar 5 has a placement groove 16, and the bottom of the mounting box 2 is installed inside the placement groove 16 and is horizontally positioned, with its bottom end suspended between the top of the support plate 6 and the top of the support bar 5.

[0025] Therefore, the circuit breaker body 3 is fixedly installed on the top of the mounting box 2, and the mounting box 2 is installed on the top of the support plate 6 through the support bar 5 and the placement groove 16, and the bottom end is suspended, so that the bottom end of the mounting box 2 can be ventilated and cooled through the heat dissipation hole 18, and the water accumulated on the top of the support plate 6 can be quickly drained through the drain hole 15, so as to avoid the bottom end of the mounting box 2 from being soaked in water and affecting the safe use of the pole-mounted circuit breaker.

[0026] The snap-fit ​​installation mechanism includes drainage holes 15 evenly distributed on the surface of the support plate 6, mounting rods 4 fixed at the four corners of the bottom of the mounting box 2 and sliding through the drainage holes 15, and snap-fit ​​blocks 17 elastically mounted on the surface of the mounting rods 4 and snap-fitted to the bottom of the support plate 6.

[0027] In a preferred embodiment, the mounting rod 4 is vertically positioned, and recessed mounting clips 17 are provided on both sides of its surface. A through hole 20 is provided in the middle of the inner end of the recess 19. The recess 19 is a rectangular groove structure and is horizontally positioned.

[0028] In a preferred embodiment, the snap-fit ​​block 17 is slidably snap-fitted into the interior of the groove 19, and a spring 21 is connected between the two snap-fit ​​blocks 17, with the spring 21 sliding through the through hole 20.

[0029] Mounting box 2 is installed on the top of support plate 6. Mounting rod 4 passes through drain hole 15. Snap-fit ​​block 17 retracts into groove 19 and compresses spring 21. After groove 19 moves below support plate 6, the two ends of spring 21 spring outwards to snap-fit ​​block 17, ejecting the outer end of snap-fit ​​block 17 from groove 19, so that snap-fit ​​block 17 is snapped into place at the bottom of support plate 6, thus connecting mounting rod 4 to support plate 6. This facilitates quick disassembly and installation of mounting box 2 and circuit breaker body 3, and makes it easy to remove the pole-mounted circuit breaker for maintenance.

[0030] In a preferred embodiment, the clamping and mounting mechanism includes a sliding groove 13 formed on the outer side of the mounting plate 1, a sliding block 23 slidably mounted inside the sliding groove 13, a clamping plate 11 fixed on the outer side of the sliding block 23, and a clamping groove 12 formed on the inner side of the clamping plate 11.

[0031] In a preferred embodiment, both the sliding groove 13 and the sliding block 23 have T-shaped cross-sections and are horizontally arranged. The clamping plate 11 is a rectangular plate structure and is vertically slidably installed on the outside of the mounting plate 1. The clamping groove 12 is a V-shaped groove structure.

[0032] In a preferred embodiment, the sliding block 23 has a threaded hole 22 in the middle, and the sliding groove 13 has rotating holes 14 at both ends. A threaded rod 10 is rotatably installed inside the sliding groove 13. The threaded rod 10 is threadedly assembled with the threaded hole 22, and its two ends pass through the rotating holes 14. Nuts 8 are connected to the two end surfaces and located outside the rotating holes 14. Rotating bars 9 are fixed at both ends of the threaded rod 10.

[0033] When installing the pole-mounted circuit breaker, rotating the rotating bar 9 and the threaded rod 10 drives the sliding block 23 to move left and right inside the sliding groove 13 through the threaded hole 22, thereby adjusting the position of the two clamping plates 11 and the distance between them. This makes it easier to fasten the mounting plate 1 to the external structure through the clamping groove 12. In this way, it is easy to flexibly adjust the position of the mounting plate 1 and the installation position of the pole-mounted circuit breaker.

[0034] In use, a support plate 6 is fixed to the side of the mounting plate 1, and support bars 5 are evenly fixed to the top of the support plate 6. Thus, the circuit breaker body 3 is fixedly installed on the top of the mounting box 2. The mounting box 2 is installed on the top of the support plate 6 through the support bars 5 and the placement groove 16, and the bottom end is suspended, which facilitates ventilation and heat dissipation of the bottom end of the mounting box 2 through the heat dissipation holes 18. The water accumulated on the top of the support plate 6 can be quickly drained through the drainage holes 15, so as to avoid the bottom end of the mounting box 2 from being soaked in water and affecting the safe use of the pole-mounted circuit breaker.

[0035] Mounting box 2 is installed on the top of support plate 6. Mounting rod 4 passes through drain hole 15. Snap-fit ​​block 17 retracts into groove 19 and compresses spring 21. After groove 19 moves below support plate 6, the two ends of spring 21 spring outwards to snap-fit ​​block 17, ejecting the outer end of snap-fit ​​block 17 from groove 19, so that snap-fit ​​block 17 is snapped into place at the bottom of support plate 6, thus connecting mounting rod 4 to support plate 6. This facilitates quick disassembly and installation of mounting box 2 and circuit breaker body 3, and makes it easy to remove the pole-mounted circuit breaker for maintenance.

[0036] Sliding block 23 and clamping plate 11 are slidably installed on the outside of mounting plate 1 via sliding groove 13. Therefore, when installing the pole-mounted circuit breaker, rotating bar 9 and threaded rod 10 are rotated, and sliding block 23 is driven to move left and right inside sliding groove 13 through threaded hole 22, thereby adjusting the position of the two clamping plates 11 and the distance between them. This makes it easier to fasten mounting plate 1 to the external structure via clamping groove 12. In this way, it is easy to flexibly adjust the position of mounting plate 1 and the installation position of pole-mounted circuit breaker.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
