Description
Technical Field
[0001] This invention belongs to the field of pole-mounted circuit breaker installation technology, and in particular relates to a safe installation structure for pole-mounted circuit breakers. Background Technology
[0002] With the rapid development of my country's economy and the continuous increase in power supply, especially with the increasing dependence of various customers on electricity, pole-mounted circuit breakers are often used on the interconnection, sectionalizing and branch lines of the power grid to improve the reliability of power supply.
[0003] Since pole-mounted circuit breakers are directly installed on utility poles, they are currently mostly fixed to the pole using a triangular mounting bracket. The circuit breaker is then hoisted to a higher position using a lifting or hoisting mechanism and installed on the bracket. After installation, the hoisting ropes need to be removed, making the process cumbersome. Furthermore, pole-mounted circuit breakers are quite heavy, and after prolonged use, the triangular mounting bracket is prone to deformation, posing a safety hazard. To address these issues, we have designed a safer installation structure for pole-mounted circuit breakers. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
[0005] This invention relates to a safe installation structure for a pole-mounted circuit breaker, comprising a utility pole, a pole-mounted circuit breaker body, and a fixing frame. A fixing plate is fixed to the left side of the fixing frame, and several fixing clamps are provided on the fixing plate to cooperate with the utility pole. Fixing blocks are fixed to both sides of the surface of the pole-mounted circuit breaker body, and steel ropes are connected to the fixing blocks. Support rods are fixed to the front and rear sides of the upper surface of the fixing frame, and pulley blocks are installed at the upper ends of the support rods. The movable end of the steel rope passes through the pulley blocks and is connected to a hanging ring. Reinforcing rods are hinged to the front and rear sides of the left surface of the fixing frame, and an arc-shaped plate is hinged to the end of the reinforcing rod away from the fixing frame, cooperating with the outer surface of the utility pole. A sliding groove is provided inside the fixing frame, and a support plate is slidably disposed within the sliding groove.
[0006] The fixing clamps, in conjunction with the utility pole, facilitate the fixing of the fixing plate onto the pole surface, thereby achieving the purpose of fixing the fixing frame to the utility pole. Simultaneously, the hanging rings facilitate the connection of the other end of the steel rope to the ground winch. Under the action of the pulley system, the pole-mounted circuit breaker body is pulled upwards, passing through the fixing frame. Combined with the cooperation of the sliding groove and the support plate, the support plate is easily pushed into the fixing frame, providing support to the bottom of the pole-mounted circuit breaker body, ensuring its stability and the safety of the installation structure. Once the pole-mounted circuit breaker body has moved onto the support plate, the hanging rings facilitate the separation of the steel rope from the ground winch, eliminating the need to dismantle the steel rope and saving manpower.
[0007] Preferably, the fixing clamp is threaded with several fixing bolts.
[0008] Preferably, the two arc-shaped plates are connected by a number of fixing bolts, and the arc-shaped plates are threadedly fitted with a number of fastening bolts on the utility pole. Under the action of the fastening bolts, the arc-shaped plates are easily fixed to the utility pole. Under the action of the reinforcing rod, the fixed frame is effectively reinforced and supported, preventing the installation structure from deforming due to the weight of the pole-mounted circuit breaker body during later use, thus ensuring the service life of the installation structure.
[0009] Preferably, a connecting plate is bolted to the lower surface of the support plate, a threaded tube is hinged to the lower surface of the connecting plate, a threaded rod is threaded inside the threaded tube, and a limit plate is hinged to the end of the threaded rod away from the connecting plate.
[0010] Preferably, the limiting plate has a semi-circular structure that mates with the outer surface of the utility pole. Several locking bolts are threaded onto the limiting plate. The semi-circular structure of the limiting plate, in conjunction with the utility pole, facilitates adjustment of the limiting plate's fit against the outer surface of the utility pole. The locking bolts then fix the limiting plate to the utility pole. Combined with the threaded tube and threaded rod, a triangular support structure is formed between the support plate and the utility pole, further ensuring the stability of the installation structure.
[0011] Preferably, safety buckles are provided on both sides of the limiting plate surface, which cooperate with the hanging ring.
[0012] Preferably, the fixed frame has a plurality of first positioning holes on both its front and rear surfaces, the first positioning holes being connected to the sliding groove, and the support plate has a plurality of second positioning holes on both its front and rear surfaces, the first positioning holes and the second positioning holes being one-to-one and cooperating with each other.
[0013] Preferably, reinforcing ribs are provided between the upper and lower surfaces of the fixed frame and the fixed plate.
[0014] Preferably, the inner surfaces of the fixing clamp, the arc plate, and the limiting plate are all provided with anti-slip pads.
[0015] The present invention has the following beneficial effects:
[0016] 1. This invention, through the cooperation of a fixing clamp and a utility pole, facilitates the fixing of a fixing plate onto the surface of the utility pole, thereby achieving the purpose of fixing the fixing frame to the utility pole. Simultaneously, the hanging ring facilitates the connection of the other end of the steel rope to a ground winch. Under the action of the pulley system, the pole-mounted circuit breaker body is pulled upwards, passing through the fixing frame. Combined with the cooperation of the sliding groove and the support plate, the support plate is easily pushed into the fixing frame, providing support to the bottom of the pole-mounted circuit breaker body, ensuring the stability of the pole-mounted circuit breaker body and the safety of the installation structure. When the pole-mounted circuit breaker body moves to the support plate, the hanging ring facilitates the separation of the steel rope from the ground winch, eliminating the need to dismantle the steel rope and saving manpower.
[0017] 2. The present invention facilitates the fixing of the arc-shaped plate to the utility pole by means of fastening bolts. Under the action of the reinforcing rod, it effectively strengthens and supports the fixed frame, preventing deformation of the installation structure due to the weight of the pole-mounted circuit breaker body during later use, thus ensuring the service life of the installation structure.
[0018] 3. This invention utilizes the threaded engagement of the threaded tube and the threaded rod to facilitate adjustment, allowing the threaded rod to be screwed away from the support plate. Combined with the semi-circular structure of the limiting plate and its interaction with the utility pole, as well as the hinged action between the threaded tube and the connecting plate and the threaded rod and the limiting plate, it facilitates adjustment of the limiting plate to fit against the outer surface of the utility pole. Under the action of the locking bolt, the limiting plate is fixed to the utility pole. The combination of the threaded tube and the threaded rod forms a triangular support structure between the support plate and the utility pole, further ensuring the stability of the installation structure.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0032] Please see Figures 1-7As shown, the present invention is a safety installation structure for a pole-mounted circuit breaker, including a utility pole 1, a pole-mounted circuit breaker body 2, and a fixing frame 3. A fixing plate 4 is fixed to the left side of the fixing frame 3, and several fixing clamps 5 are provided on the fixing plate 4 to cooperate with the utility pole 1. Fixing blocks 7 are fixed on both sides of the surface of the pole-mounted circuit breaker body 2, and steel ropes 8 are connected to the fixing blocks 7. Support rods 9 are fixed on both the front and rear sides of the upper surface of the fixing frame 3. A pulley group 10 is installed on the upper end of the support rod 9, and the movable end of the steel rope 8 passes through the pulley group 10 and is connected to a hanging ring 11. Reinforcing rods 12 are hinged to both the front and rear sides of the left surface of the fixing frame 3. An arc-shaped plate 13 is hinged to the end of the reinforcing rod 12 away from the fixing frame 3 to cooperate with the outer surface of the utility pole 1. A sliding groove 15 is opened inside the fixing frame 3, and a support plate 16 is slidably arranged in the sliding groove 15.
[0033] By using the fixing clamp 5 in conjunction with the utility pole 1, the fixing plate 4 can be easily fixed to the surface of the utility pole 1, thereby achieving the purpose of fixing the fixing frame 3 to the utility pole 1. At the same time, the hanging ring 11 facilitates the connection of the other end of the steel rope 8 to the ground winch. Under the action of the pulley block 10, the pole-mounted circuit breaker body 2 is pulled upward and passes through the fixing frame 3. With the cooperation of the sliding groove 15 and the support plate 16, the support plate 16 can be pushed into the fixing frame 3, providing support for the bottom of the pole-mounted circuit breaker body 2, ensuring the stability of the pole-mounted circuit breaker body 2, and ensuring the safety of the installation structure. When the pole-mounted circuit breaker body 2 moves onto the support plate 16, the hanging ring 11 facilitates the separation of the steel rope 8 from the ground winch, eliminating the need to remove the steel rope 8 and saving manpower.
[0034] The fixing clamp 5 is threaded with several fixing bolts 6, and the two arc-shaped plates 13 are connected by several fixing bolts 6. The arc-shaped plates 13 and the utility pole 1 are threaded with several fastening bolts 14. The fixing bolts 6 make it easy to tightly clamp the fixing clamp 5 and the arc-shaped plates 13 onto the utility pole 1. Combined with the action of the fastening bolts 14, the arc-shaped plates 13 are further fixed onto the utility pole 1. Under the action of the reinforcing rod 12, the fixing frame 3 is effectively reinforced and supported, preventing the installation structure from deforming due to the gravity of the pole-mounted circuit breaker body 2 during later use, thus ensuring the service life of the installation structure.
[0035] A connecting plate 25 is bolted to the lower surface of the support plate 16. A threaded tube 17 is hinged to the lower surface of the connecting plate 25. A threaded rod 18 is threaded inside the threaded tube 17. A limiting plate 19 is hinged to the end of the threaded rod 18 away from the connecting plate 25. The limiting plate 19 has a semi-circular structure and mates with the outer surface of the utility pole 1. Several locking bolts 20 are threaded on the limiting plate 19. The bolts facilitate fixing the connecting plate 25 to the lower surface of the support plate 16. At the same time, the threaded engagement between the threaded tube 17 and the threaded rod 18 facilitates adjusting the threaded rod 18 away from the support plate 16. The screw is rotated outwards, and combined with the hinged action of the threaded tube 17 and the connecting plate 25, the hinged action of the threaded rod 18 and the limiting plate 19, and the mutual cooperation between the semi-circular structure of the limiting plate 19 and the utility pole 1, it is easy to adjust the limiting plate 19 to fit against the outer surface of the utility pole 1. Under the action of the locking bolt 20, the limiting plate 19 is fixed on the utility pole 1. Combined with the threaded tube 17 and the threaded rod 18, a triangular support structure is formed between the support plate 16 and the utility pole 1, which further ensures the stability of the installation structure, and thus ensures the stability of the pole-mounted circuit breaker body 2.
[0036] Safety latches 21 are provided on both sides of the limit plate 19, which cooperate with the hanging ring 11. Through the cooperation of the safety latches 21 and the hanging ring 11, the hanging ring 11 can be easily locked on the safety latches 21. Under the action of the steel rope 8, the pole-mounted circuit breaker body 2 is effectively pulled, further ensuring the stability of the pole-mounted circuit breaker body 2.
[0037] Anti-slip pads are provided on the inner surfaces of the fixing clamp 5, the arc plate 13, and the limiting plate 19. The anti-slip pads effectively increase the friction between the fixing clamp 5, the arc plate 13, and the limiting plate 19 and the utility pole 1, ensuring the stability of the installation structure.
[0038] The fixed frame 3 has several first positioning holes 22 on both its front and rear surfaces. The first positioning holes 22 are connected to the slide groove 15. The support plate 16 has several second positioning holes 23 on both its front and rear surfaces. The first positioning holes 22 and the second positioning holes 23 correspond one to one and cooperate with each other. With the cooperation of the first positioning holes 22 and the second positioning holes 23, it is easy to screw the bolts into the fixed frame 3 and the support plate 16, thereby ensuring the stability between the support plate 16 and the fixed frame 3.
[0039] Reinforcing ribs 24 are provided between the upper and lower surfaces of the fixed frame 3 and the fixed plate 4, which increases the stability between the fixed frame 3 and the fixed plate 4.
[0040] Example: When installing the pole-mounted circuit breaker, the fixing clamp 5 is clamped at a suitable height on the utility pole 1, and the fixing bolt 6 is used to tighten the fixing clamp 5 on the utility pole 1. With the action of the fixing plate 4, the fixing frame 3 is fixed to the utility pole 1. Combined with the hinge action of the reinforcing rod 12, the arc plate 13 is adjusted to fit against the utility pole 1. Then, the two adjacent arc plates 13 are firmly connected together by the fixing bolt 6. At the same time, the fastening bolt 14 is adjusted to screw into the surface of the arc plate 13 until it is screwed into the inside of the utility pole 1, fixing the arc plate 13 to the surface of the utility pole 1. This further increases the stability of the connection between the fixing frame 3 and the utility pole 1, realizes the reinforcement of the fixing frame 3, and ensures the stability of the fixing frame 3.
[0041] Then, adjust the hanging ring 11 to drive the steel rope 8 through the inside of the fixed frame 3 and the inside of the pulley block 10, and connect the hanging ring 11 to the winch on the ground. Through the operation of the winch, the internal rope is wound up, pulling the hanging ring 11 to move downward, which in turn drives the pole-mounted circuit breaker body 2 to move upward until the pole-mounted circuit breaker body 2 passes through the inside of the fixed frame 3, and the winch stops winding.
[0042] At this time, with the cooperation of the slide 15 and the support plate 16, the support plate 16 is pushed from the outside to the inside of the fixed frame 3 until the support plate 16 is completely pushed into the fixed frame 3. The adjusting bolt is screwed into the first positioning hole 22 and the second positioning hole 23 to make the support plate 16 and the fixed frame 3 stably connected together. Then, the ground winch is driven to release the rope, so that the pole-mounted circuit breaker body 2 falls onto the support plate 16. At this time, the hanging ring 11 is removed from the rope of the winch.
[0043] Simultaneously, the connecting plate 25 is fixed to the lower surface of the support plate 16 with bolts. Under the threaded engagement of the threaded tube 17 and the threaded rod 18, combined with the hinged action of the threaded tube 17 and the connecting plate 25, and the hinged action of the threaded rod 18 and the limiting plate 19, the threaded rod 18 is adjusted to be screwed outward until the inner wall of the limiting plate 19 is fitted against the utility pole 1. At this time, the locking bolt 20 is adjusted to be screwed inward into the utility pole 1, so that the limiting plate 19 is fixed on the utility pole 1. At this time, under the combined action of the threaded tube 17 and the threaded rod 18, a triangular support structure is formed between the lower surface of the support plate 16 and the utility pole 1, which further supports the bottom of the installation structure, ensuring the stability of the installation structure and the pole-mounted circuit breaker. The hanging ring 11 is hung on the safety lock buckle 21, so that the steel rope 8 is in a stretched state. Finally, the base of the pole-mounted circuit breaker body 2 is fixed to the support plate 16 by bolts or welding, completing the installation of the pole-mounted circuit breaker.
[0044] This invention uses the hanging ring 11 to connect with the rope on the ground winch. After the pole-mounted circuit breaker body 2 is hoisted to the installation height by the steel rope 8, there is no need to remove the steel rope 8 from the pole-mounted circuit breaker body 2, saving manpower. At the same time, the hanging ring 11 is hung on the safety lock 21, and the steel rope 8 effectively tightens the pole-mounted circuit breaker body 2, further ensuring the stability of the pole-mounted circuit breaker body 2.
[0045] The combined action of the fixing clamp 5, the arc plate 13, the reinforcing rod 12, the threaded pipe 17, the threaded rod 18, and the limiting plate 19 provides support and reinforcement for the installation structure, ensuring its stability and effectively preventing deformation caused by the gravity of the pole-mounted circuit breaker body 2. This ensures the stability and safety of the pole-mounted circuit breaker body 2 during use.
