Description

Technical Field

[0001] This utility model relates to the field of high voltage electrical technology, and in particular to a primary and secondary deep integrated intelligent capacitor power supply pole-mounted circuit breaker. Background Technology

[0002] In power systems, pole-mounted circuit breakers, as crucial electrical equipment, undertake the critical task of controlling and protecting circuits. Pole-mounted circuit breakers typically need to be installed on high utility poles, requiring operators to perform installation operations at height. Furthermore, traditional pole-mounted circuit breakers present the following installation challenges:

[0003] Traditional pole-mounted circuit breaker installation methods often rely on fasteners such as bolts and nuts for fixation. Installation requires tightening multiple bolts one by one, which is cumbersome. Moreover, the high-altitude environment makes it inconvenient for operators, causing psychological stress and easily leading to insecure installation, which affects the normal operation of the circuit breaker. At the same time, due to the complexity of the installation process, operators spend a long time working at height, which increases the risk of safety accidents. Furthermore, once problems occur after installation and repairs or replacements are needed, the disassembly process is also difficult, which increases maintenance costs and difficulty.

[0004] To address the aforementioned issues, this utility model document proposes a primary and secondary deep integration intelligent capacitor-driven pole-mounted circuit breaker. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the traditional pole-mounted circuit breaker being fixed by bolts and nuts, which is cumbersome to install, inconvenient to maintain and disassemble, and inconvenient to operate at heights and poses safety risks during long-term operation. The proposed invention is a deep integration of primary and secondary intelligent capacitor power supply pole-mounted circuit breaker.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A primary and secondary deeply integrated intelligent capacitor-driven pole-mounted circuit breaker includes:

[0008] The circuit breaker body has a mounting base fixedly installed at its bottom. The mounting base has a clamping plate at its bottom. The clamping plate cooperates with the mounting base to clamp and fix multiple mounting brackets installed on the corresponding utility poles, so as to complete the installation of the circuit breaker body.

[0009] It also includes a lifting assembly, which includes a connecting shaft, two screws and a self-locking mechanism. Both screws are threadedly engaged with the clamping plate. When the connecting shaft rotates, it can drive both screws to rotate simultaneously, thereby allowing the clamping plate to move closer to the mounting base with the help of the self-locking mechanism, so as to fix the circuit breaker body to multiple mounting brackets.

[0010] In one possible design, the lifting assembly further includes a fixed base fixedly installed at the bottom of the mounting base. The connecting shaft is rotatably installed at the bottom of the mounting base, with both ends of the connecting shaft rotatably passing through both sides of the fixed base. A first bevel gear is fixedly installed at both ends of the connecting shaft. Both screws rotatably pass through the mounting base, and a second bevel gear is fixedly sleeved on the outer wall of each of the two screws. The two second bevel gears are located below the mounting base, and the installation directions of the two second bevel gears are opposite. Both second bevel gears mesh with adjacent first bevel gears to simultaneously complete the same-direction rotation drive of the two screws.

[0011] In one possible design, the self-locking mechanism includes a worm gear fixedly sleeved on the outer wall of the connecting shaft, a worm rotatably mounted inside the fixed seat, the worm meshing with the worm gear, one end of the worm rotatably passing through one side of the fixed seat, and a handwheel fixedly mounted on one end of the worm for convenient rotation of the worm.

[0012] In one possible design, two limiting plates are fixedly installed on both sides of the clamping plate, and multiple limiting plates slide through the mounting base. Fixing blocks are fixedly installed on both sides of the clamping plate, and two fixing blocks are threadedly connected to adjacent screws to realize the lifting and lowering of the clamping plate.

[0013] In one possible design, multiple fixing plates are fixedly installed on the top of the clamping plate. The multiple fixing plates are evenly arranged, and a fixing groove is formed between two adjacent fixing plates. The multiple fixing grooves cooperate with the corresponding mounting brackets to complete the fixing of the circuit breaker body.

[0014] In one possible design, a rubber pad is fixedly installed at the bottom of the mounting base. The bottom of the rubber pad mates with the top of multiple mounting plates. Multiple rubber protrusions are fixedly installed on the inner walls of the bottom of multiple mounting grooves. The multiple rubber protrusions located in the same mounting groove are evenly arranged. Each of the multiple rubber protrusions mates with a corresponding mounting bracket. The rubber pad and the multiple rubber protrusions are used to ensure the stable clamping of the clamping plate and mounting base on the multiple mounting brackets, thereby ensuring the stable installation of the circuit breaker body.

[0015] In one possible design, multiple positioning plates are fixedly installed on the side of the clamping plate near the handwheel, and corresponding positioning bolts pass through the multiple positioning plates. The multiple mounting brackets are provided with corresponding positioning holes, and the multiple positioning bolts pass through the corresponding positioning holes to prevent the equipment from sliding after installation.

[0016] In this application, during use, the user can use an external suspension device to suspend the circuit breaker body to the location where multiple mounting brackets are installed. Before installation, the clamping plate and the mounting base are separated by a certain distance. Then, the user can control the suspended device to be installed to move, ensuring that multiple mounting brackets pass through the space between the mounting base and the clamping plate. Afterward, the user only needs to turn the handwheel, which drives the worm gear to rotate, and in turn, the connecting shaft rotates under the transmission of the worm gear. At this time, the screws on both sides can rotate simultaneously, thus ensuring that the clamping plate gradually approaches the mounting base. During the process of bringing the clamping plate and the mounting base closer, the user needs to ensure that multiple mounting brackets are engaged in the corresponding fixing slots. At the same time, the user also needs to ensure that the holes in the positioning plate are aligned with the corresponding positioning holes on the mounting brackets. Afterward, the user can insert the positioning bolts through the corresponding mounting brackets and fixing slots. The positioning plate is used to initially position the equipment. Next, the user can continue turning the handwheel until the clamping plate is firmly against the rubber pad. The squeezing and clearance effect of the rubber pad and multiple rubber protrusions ensures that the multiple mounting brackets are not easily moved in their corresponding fixing slots. Simultaneously, the self-locking mechanism formed by the worm gear and worm ensures a stable locking effect between the clamping plate and the mounting base. After installation, tightening the multiple positioning bolts ensures that the equipment will not move horizontally, further ensuring stable installation. Finally, disconnecting the suspended equipment allows for the connection of the circuit breaker body to the wiring. Through the cooperation of the clamping plate and the mounting base, the user can quickly complete the installation of the circuit breaker body, reducing the amount of manual operation, facilitating rapid completion of high-altitude work, improving work efficiency, and ensuring operator safety.

[0017] Beneficial effects: In this utility model, the intelligent capacitor-driven pole-mounted circuit breaker with deep integration of primary and secondary power supply, through the design of the lifting component, allows the user to drive two screws to rotate simultaneously by simply turning the handwheel, bringing the clamping plate closer to the mounting base, thereby quickly fixing the circuit breaker body to multiple mounting brackets. Compared with the traditional installation method of tightening bolts one by one, this device greatly shortens the installation time and improves the installation efficiency. Operators do not need to perform complex bolt tightening operations at height; they can complete the installation simply by turning the handwheel, reducing the difficulty of operation, reducing the labor intensity of operators, and further reducing the time operators spend working at height, thus reducing the risk of safety accidents and ensuring the safety of operators' lives.

[0018] In this utility model, the intelligent capacitor power tap-on circuit breaker with deep integration of primary and secondary power supply has fixing blocks on both sides of the clamping plate that are threadedly connected to the screw, ensuring that the clamping plate can be raised and lowered smoothly; the self-locking mechanism adopts the meshing of worm gear and worm, which can effectively prevent the screw from reversing after the clamping plate is pressed against the mounting base, ensuring a stable locking effect between the clamping plate and the mounting base.

[0019] In this utility model, the intelligent capacitor-driven power-collecting pole-mounted circuit breaker with deep integration of primary and secondary components features a clamping plate with multiple fixing plates and grooves on its top. These, in conjunction with the mounting bracket, enable precise positioning and installation of the bracket. The design of rubber pads and multiple rubber protrusions further enhances the stable clamping effect of the clamping plate and mounting base on the mounting bracket, ensuring the secure installation of the circuit breaker body. The design of the positioning plate and positioning bolts prevents slippage of the installed equipment, further improving its stability and safety.

[0020] In this invention, the intelligent capacitor-driven power supply pole-mounted circuit breaker with deep integration of primary and secondary components utilizes a lifting assembly design. Users can drive the screw to rotate by turning the handwheel, bringing the clamping plate closer to the mounting base for quick and easy device fixation. This reduces operational difficulty and labor intensity, minimizes high-altitude work time, and lowers operational risks. An internal self-locking mechanism prevents screw reversal, ensuring stable locking. Rubber pads and protrusions enhance the clamping effect, while positioning plates and bolts further prevent slippage, effectively improving the device's stability and safety, and ensuring the stable operation of the power system.

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Refer to Figure 1-5 A pole-mounted circuit breaker, comprising:

[0029] The circuit breaker body 1 has a mounting base 3 fixedly installed at its bottom. The mounting base 3 has a clamping plate 4 at its bottom. The clamping plate 4 cooperates with the mounting base 3 to clamp and fix multiple mounting brackets 2 installed on the corresponding utility poles, so as to complete the installation of the circuit breaker body 1.

[0030] This embodiment also includes a lifting assembly, which includes a connecting shaft 7, two screws 11 and a self-locking mechanism. Both screws 11 are threadedly engaged with the clamping plate 4. When the connecting shaft 7 rotates, it can simultaneously drive the two screws 11 to rotate, thereby completing the clamping plate 4 and the mounting base 3 to move closer together with the cooperation of the self-locking mechanism, so as to complete the fixing of the circuit breaker body 1 and multiple mounting brackets 2.

[0031] In this embodiment, the lifting assembly also includes a fixed base 5 fixedly installed at the bottom of the mounting base 3, a connecting shaft 7 rotatably installed at the bottom of the mounting base 3, and the two ends of the connecting shaft 7 respectively rotatably passing through the two sides of the fixed base 5. A first bevel gear 12 is fixedly installed at both ends of the connecting shaft 7, and two screws 11 rotatably pass through the mounting base 3. A second bevel gear 13 is fixedly sleeved on the outer wall of each of the two screws 11. The two second bevel gears 13 are both located below the mounting base 3, and the installation directions of the two second bevel gears 13 are opposite. The two second bevel gears 13 mesh with the adjacent first bevel gear 12. When the connecting shaft 7 is rotated, it can drive the two first bevel gears 12 to rotate. With the cooperation of the two second bevel gears 13, the two screws 11 can be driven to rotate in the same direction at the same time.

[0032] In this embodiment, two limiting plates 17 are fixedly installed on both sides of the clamping plate 4. Multiple limiting plates 17 slide through the mounting base 3. Fixing blocks 18 are fixedly installed on both sides of the clamping plate 4. The two fixing blocks 18 are threadedly connected to the adjacent screws 11. When the two screws 11 rotate in the same direction, they can drive the two fixing blocks 18 to move, which in turn can drive the clamping plate 4 to move synchronously. With the cooperation of multiple limiting plates 17, the clamping plate 4 can be raised and lowered, thereby completing the installation or disassembly of the circuit breaker body 1.

[0033] In this embodiment, the self-locking mechanism includes a worm gear 8 fixedly sleeved on the outer wall of the connecting shaft 7, a worm 9 rotatably mounted inside the fixed seat 5, the worm 9 meshing with the worm gear 8, one end of the worm 9 rotatably passing through one side of the fixed seat 5, and a handwheel 10 fixedly mounted on one end of the worm 9; by rotating the handwheel 10, the user can drive the worm 9 to rotate, the worm 9 drives the worm gear 8 to rotate, and the worm gear 8 in turn drives the connecting shaft 7 to rotate; and with the cooperation of the worm gear 8 and the worm 9, the connecting shaft 7 can also be self-locked, thereby preventing the two screws 11 from reversing, and ensuring that the clamping plate 4 and the mounting base 3 can stably clamp the multiple mounting brackets 2.

[0034] In this embodiment, a plurality of fixing plates 14 are fixedly installed on the top of the clamping plate 4. The plurality of fixing plates 14 are evenly arranged, and a fixing groove 15 is formed between two adjacent fixing plates 14. The plurality of fixing grooves 15 cooperate with the corresponding mounting brackets 2. When the clamping plate 4 rises, it can drive the plurality of fixing plates 14 to rise, thereby enabling the plurality of fixing grooves 15 to cooperate with the corresponding mounting brackets 2 to complete the fixing of the circuit breaker body 1.

[0035] This application can be used in the field of high-voltage electrical technology, or in other fields applicable to this application.

[0036] Example 2: Reference Figure 3 , 5 An improvement based on Example 1: a primary and secondary deep integration intelligent capacitor power tap-on circuit breaker, which is applied to the field of high voltage electrical technology.

[0037] In this embodiment, a rubber pad 6 is fixedly installed at the bottom of the fixing base 5. The bottom of the rubber pad 6 cooperates with the top of multiple fixing plates 14. Multiple rubber protrusions 16 are fixedly installed on the bottom inner wall of multiple fixing grooves 15. The multiple rubber protrusions 16 located in the same fixing groove 15 are evenly arranged, and the multiple rubber protrusions 16 cooperate with the corresponding mounting brackets 2. The rubber pad 6 and the multiple rubber protrusions 16 are used to provide elastic clearance when clamping the multiple mounting brackets 2, which can increase the friction between the corresponding mounting brackets 2 and the inner wall of the fixing groove 15. This is beneficial to make the clamping plate 4 and the mounting base 3 clamp the multiple mounting brackets 2 more firmly, so as to ensure the stable installation of the circuit breaker body 1.

[0038] In this embodiment, multiple positioning plates 19 are fixedly installed on the side of the clamping plate 4 near the handwheel 10. Each positioning plate 19 has a corresponding positioning bolt 20 passing through it. Each mounting bracket 2 has a corresponding positioning hole inside it, and the multiple positioning bolts 20 pass through the corresponding positioning hole. When the clamping plate 4 rises and cooperates with the multiple mounting brackets 2, the multiple positioning bolts 20 are passed through the corresponding positioning holes and the positioning bolts 20 are tightened. This can prevent the equipment from sliding horizontally after installation, which further improves the stability of the circuit breaker body 1 after installation.

[0039] The working principle and usage process of this technical solution are as follows: During use, the user can use an external suspension device to suspend the circuit breaker body 1 to the position where multiple mounting brackets 2 are installed. Before installation, the clamping plate 4 and the mounting base 3 are separated by a certain distance. Then, the user can control the suspended device to be installed to move, ensuring that multiple mounting brackets 2 pass through the mounting base 3 and the clamping plate 4. Afterwards, the user only needs to turn the handwheel 10, which drives the worm gear 9 to rotate, and then drives the connecting shaft 7 to rotate under the transmission of the worm wheel 8. At this time, the screws 11 on both sides can rotate simultaneously, thus ensuring that the clamping plate 4 gradually approaches the mounting base 3. During the process of bringing the clamping plate 4 and the mounting base 3 closer together, the user needs to ensure that multiple mounting brackets 2 are engaged in the corresponding fixing slots 15. Simultaneously, the user also needs to ensure that the holes in the positioning plate 19 are aligned with the corresponding positioning holes on the mounting brackets 2. Afterwards, the user can insert the positioning bolts 20 through the mounting brackets. The corresponding mounting bracket 2 and positioning plate 19 are used to complete the initial positioning of the equipment. Next, the user can continue to turn the handwheel 10 until the clamping plate 4 is tightly pressed against the rubber pad 6. Through the squeezing and clearance effect of the rubber pad 6 and multiple rubber protrusions 16, it can be ensured that the multiple mounting brackets 2 are not easy to move in the corresponding fixing grooves 15. At the same time, with the cooperation of the self-locking mechanism formed by the worm gear 8 and worm 9, the locking effect of the clamping plate 4 and the mounting base 3 can be ensured to be relatively stable. After the installation is completed, the multiple positioning bolts 20 are tightened to ensure that the equipment will not move horizontally, which can further ensure the stable installation of the equipment. Finally, the connection of the suspended equipment can be released to connect the circuit breaker body 1. Through the cooperation of the clamping plate 4 and the mounting base 3, the user can quickly complete the installation of the circuit breaker body 1, which can reduce the user's workload, facilitate the rapid completion of high-altitude work, improve work efficiency, and ensure the safety of operators.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
