Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a primary and secondary integrated pole-mounted circuit breaker with a sliding rail mounting mechanism. Background Technology

[0002] The integrated pole-mounted circuit breaker is an intelligent complete set of equipment that integrates the primary switch body and the secondary intelligent control unit in outdoor power distribution lines. It is installed on the utility pole and solves the pain points of traditional pole-mounted circuit breakers and secondary equipment that are installed separately, such as interface mismatch, complicated wiring and low reliability. It is a key piece of equipment for the construction of smart power distribution networks.

[0003] Currently, most of the integrated primary and secondary pole-mounted circuit breakers used in distribution network lines adopt an integrated fixed installation structure. The main body of the circuit breaker is directly and firmly installed on the utility pole. After installation, the overall position cannot be adjusted. However, during the construction of distribution network lines, situations such as the utility pole being erected crookedly or the crossarm installation dimensions being inaccurate are prone to occur. The fixed structure cannot flexibly adjust the position of the main body of the circuit breaker, making it difficult to achieve precise connection of the wiring ports. Assembly and debugging are also quite difficult. Secondly, when the circuit breaker malfunctions and needs to be repaired and maintained, workers can only work around the narrow energized area. The working space is limited and there is a great risk of electric shock. If a full-range repair is required, the entire circuit breaker must be hoisted and disassembled. This not only makes the repair process cumbersome but also significantly prolongs the power outage time and seriously affects the normal power supply order in the area. Summary of the Invention

[0004] The purpose of this invention is to provide a primary and secondary integrated pole-mounted circuit breaker with a sliding rail mounting mechanism, in order to solve the problems mentioned in the background art. Most of the primary and secondary integrated pole-mounted circuit breakers used in the existing distribution network lines adopt an integrated fixed installation structure. The main body of the circuit breaker is directly and firmly installed on the utility pole. After installation, the overall position cannot be adjusted. However, during the construction of the distribution network line, it is easy to encounter problems such as the utility pole being erected crookedly and the crossarm installation dimensions being deviated. The fixed structure cannot flexibly adjust the position of the equipment, making it difficult to achieve accurate connection of the wiring ports, and the assembly and debugging are difficult.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a primary and secondary integrated pole-mounted circuit breaker with a sliding rail mounting mechanism, comprising a main body, wherein the main body has a front cavity and a rear cavity, and a speed limiting positioning mechanism and a fire extinguishing mechanism are provided on the main body. The speed limiting positioning mechanism includes a rotating rod rotatably mounted on the main body, the rotating rod rotatably penetrating into the interior of the front cavity, and a threaded rod rotatably connected to the interior of the rear cavity. The rotating rod and the threaded rod are fixedly connected. Slide rails are provided on both sides of the main body, and a base is slidably connected to the interior of both slide rails. The base is connected to the threaded rod, and the circuit breaker body is mounted on the base. Two mounting columns are fixedly connected to the front cavity, and a speed limiting disc is fixedly connected to the ends of the two mounting columns. The speed limiting disc does not contact the rotating rod, and multiple protrusions are fixedly connected to the interior of the speed limiting disc. Horizontal rails are fixedly connected to both sides of the rotating rod, and moving parts are slidably connected to the interior of the horizontal rails.

[0006] Preferably, an outer rod is fixedly connected to the outer side wall of the movable component, and a tension spring is fixedly connected to the outer side wall of the movable component. The end of the tension spring away from the movable component is fixedly connected to the inner wall of the rotating rod.

[0007] Preferably, a spring rod is fixedly connected to the ends of both mounting columns, and an outer ring is fixedly connected to both spring rods. The outer ring does not contact the rotating rod, and a pressing member is fixedly connected to the outer side wall of the outer ring.

[0008] Preferably, the fire extinguishing mechanism includes a storage chamber fixedly connected to the main body of the equipment. The side wall of the storage chamber has an addition port. Two fixing members are fixedly connected to the outer side wall of the storage chamber. A nozzle is fixedly connected to each of the two fixing members. A transfer tube is slidably connected to the end of the nozzle. The transfer tube has multiple through holes. The end of the transfer tube away from the nozzle slides through into the interior of the storage chamber. The end of the transfer tube inside the storage chamber is sealed, and the end inside the nozzle is open.

[0009] Preferably, two electric push rods are fixedly connected to the fixing member, and the ends of the two electric push rods are jointly fixedly connected to a side plate, which is connected to the moving tube.

[0010] Preferably, a rigid branch pipe is connected to the end of the nozzle away from the side plate, and a pressing rod is slidably connected to the end of the rigid branch pipe. A pressing spring is sleeved on the end of the pressing rod inside the rigid branch pipe, and a caster wheel is provided on the end of the pressing rod outside the rigid branch pipe. The ends of the two rigid branch pipes away from the pressing rod are connected to a jet nozzle.

[0011] Preferably, a crank handle is fixedly connected to the end of the rotating rod, and a telescopic membrane is fixedly connected to the base, with the end of the telescopic membrane away from the base connected to the outer wall of the main body of the equipment.

[0012] Preferably, the outer wall of the main body of the equipment is provided with a maintenance platform, and the base is provided with rollers, which make rolling contact with the side wall of the slide rail.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention allows for flexible fine-tuning of the circuit breaker's main installation position, adapting to various on-site installation deviations, achieving precise connection of wiring ports, reasonably relieving tensile stress in conductors, adapting to various wiring methods, and facilitating future line modifications and equipment upgrades. Simultaneously, it allows the circuit breaker main body to be smoothly moved to the maintenance platform for work, increasing the safe distance between personnel and high-voltage live areas, eliminating safety hazards associated with working at heights, enabling comprehensive fault diagnosis without disassembling the entire unit, simplifying maintenance processes, and improving maintenance efficiency. Through a speed-limiting structure, when the rotating rod drives the threaded rod too fast, it automatically limits the movement speed of the circuit breaker main body, preventing imbalance, line damage, and damage to internal precision parts caused by excessive displacement of the circuit breaker main body, thus extending the overall service life of the circuit breaker main body.

[0014] 2. When the circuit breaker body catches fire, the invention can activate the internally pressurized dry powder fire extinguishing structure. Relying on high-pressure gas to deliver ultra-fine dry powder in a directional manner, it is not affected by open wind and can accurately deliver it to the fire location to quickly isolate oxygen and suppress fire. At the same time as extinguishing the fire, the rotating rod is forcibly locked, which restricts the rotation of the threaded rod from the structure. This effectively prevents operators from accidentally moving the faulty circuit breaker body during emergency response, further standardizes the on-site emergency repair process, and comprehensively improves the operational safety performance of the circuit breaker body in the fire state.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Example 1: Please refer to Figures 1-11 A primary and secondary integrated pole-mounted circuit breaker with a sliding rail mounting mechanism includes a main body 4. The main body 4 has a front cavity 34 and a rear cavity 35. The main body 4 is equipped with a speed limiting positioning mechanism and a fire extinguishing mechanism. The speed limiting positioning mechanism includes a rotating rod 5 rotatably mounted on the main body 4, which rotatably passes through the interior of the front cavity 34. A threaded rod 9 is rotatably connected to the interior of the rear cavity 35. The rotating rod 5 and the threaded rod 9 are fixedly connected. Slide rails 7 are provided on both sides of the main body 4. A base 2 is slidably connected to the interior of both slide rails 7. The base 2 is connected to the threaded rod 9. The circuit breaker body 1 is mounted on the base 2. Two mounting posts 23 are fixedly connected to the front cavity 34. A speed limiting disc 22 is fixedly connected to the ends of the two mounting posts 23. The speed limiting disc 22 does not contact the rotating rod 5. Multiple protrusions 26 are fixedly connected to the interior of the speed limiting disc 22. Horizontal rails 27 are fixedly connected to both sides of the rotating rod 5. Moving parts 28 are slidably connected to the interior of the horizontal rails 27.

[0019] An outer rod 29 is fixedly connected to the outer wall of the movable part 28, and a tension spring 31 is fixedly connected to the outer wall of the movable part 28. The end of the tension spring 31 away from the movable part 28 is fixedly connected to the inner wall of the rotating rod 5.

[0020] Spring rods 24 are fixedly connected to the ends of the two mounting posts 23. An outer ring 25 is fixedly connected to both spring rods 24. The outer ring 25 does not contact the rotating rod 5. A pressing member 30 is fixedly connected to the outer side wall of the outer ring 25.

[0021] In this embodiment, during actual assembly and use, the staff can erect and install the main body 4 of the equipment to the installation height required for the actual operation of the main body 1 of the circuit breaker. After completing the overall fixed assembly of the main body 4, the operator can manually turn the crank handle 8, which drives the threaded rod 9 to rotate via the power transmission of the rotating rod 5. During the rotation, the threaded rod 9 can drive the main body 1 of the circuit breaker to move linearly along the slide rail 7 based on the base 2, thereby completing the precise fine adjustment of the installation position of the main body 1 of the circuit breaker. The linear displacement adjustment of the main body 1 of the circuit breaker can be achieved by using the slide rail 7, which can effectively adapt to on-site construction and installation errors such as the tilt of outdoor power poles and the deviation of crossarm installation dimensions. It can accurately complete the docking and assembly of primary and secondary integrated wiring ports, and can also reasonably relieve the tensile stress of overhead transmission lines caused by environmental temperature changes. It can adapt to various line layout installation forms, and can also reserve sufficient displacement adjustment space for the later routine maintenance and repair of the main body 1 of the circuit breaker and the upgrading and transformation of distribution network lines, effectively improving the on-site universal adaptability of the entire set of power distribution equipment.

[0022] When maintenance work is required on the internal components and electrical circuits of the circuit breaker body 1, the above-mentioned hand-cranked transmission displacement principle can be used to smoothly move the circuit breaker body 1 to one side of the maintenance platform 3. Maintenance personnel can stand directly on the maintenance platform 3 to carry out maintenance work. By moving the faulty circuit breaker body 1 to a dedicated maintenance area, the safe working distance between maintenance personnel and high-voltage live parts can be effectively increased, avoiding the electric shock safety hazards of high-altitude live work from a structural perspective. At the same time, after the circuit breaker body 1 is moved out of the original installation limit area, there is no structural obstruction, which makes it convenient for maintenance personnel to conduct a comprehensive inspection of the internal operating mechanism, intelligent control components and wiring of the circuit breaker body 1, significantly improving the overall work efficiency of the maintenance of the distribution network circuit breaker body 1.

[0023] When the operator turns the crank handle 8 and drives the threaded rod 9 through the rotating rod 5 to perform translational operation, if the operator's skill level is insufficient, the rotating rod 5 may rotate too fast. In this high-speed state, the rotating rod 5 will synchronously drive the moving part 28 to rotate at high speed as well. The moving part 28 will generate a large centrifugal force under high-speed rotation. This centrifugal force can overcome the elastic tension of the tension spring 31, thereby pushing the outer rod 29 to extend outward. As the rotating rod 5 continues to rotate, the extended outer rod 29 can form a rigid abutment limit with the protrusion 26, directly restricting the rotation of the rotating rod 5. This serves as a direct reminder to the operator that the current rotation speed is exceeding the limit. Through this centrifugal automatic speed limiting structure, the rotation speed of the rotating rod 5 driving the threaded rod 9 can always be maintained within a reasonable working range, thereby ensuring that the translational fine-tuning speed of the circuit breaker body 1 is stable and controllable. If the translational speed of the circuit breaker body 1 is too fast, it will not only easily cause the center of gravity of the distribution circuit breaker body 1 to shift and the body to shake and tilt, but also easily pull and damage the external high voltage leads, low voltage control lines and various integrated plug-in components of the circuit breaker body 1. At the same time, the mechanical vibration generated by rapid movement can easily impact and damage the precision core components such as the vacuum interrupter inside the circuit breaker, greatly shortening the actual service life of the entire mechanical transmission structure and the electrical circuit breaker body 1.

[0024] Example 2: Please refer to Figures 1-11 The fire extinguishing mechanism includes a storage chamber 6 fixedly connected to the main body 4 of the equipment. The side wall of the storage chamber 6 is provided with an addition port 10. Two fasteners 13 are fixedly connected to the outer side wall of the storage chamber 6. A nozzle 14 is fixedly connected to each of the two fasteners 13. A transfer tube 15 is slidably connected to the end of the nozzle 14. Multiple through holes 18 are provided on the transfer tube 15. The end of the transfer tube 15 away from the nozzle 14 slides through into the interior of the storage chamber 6. The end of the transfer tube 15 inside the storage chamber 6 is sealed, and the end inside the nozzle 14 is open.

[0025] Two electric push rods 17 are fixedly connected to the fastener 13. The ends of the two electric push rods 17 are fixedly connected to a side plate 16, which is connected to the moving tube 15.

[0026] The end of the nozzle 14 away from the side plate 16 is connected to a rigid branch pipe 21. The end of the rigid branch pipe 21 is slidably connected to a pressing rod 19. The end of the pressing rod 19 located inside the rigid branch pipe 21 is fitted with a pressing spring 20. The end of the pressing rod 19 located outside the rigid branch pipe 21 is provided with a caster wheel 33. The ends of the two rigid branch pipes 21 away from the pressing rod 19 are connected to a jet nozzle 12.

[0027] A crank 8 is fixedly connected to the end of the rotating rod 5, and a telescopic membrane 32 is fixedly connected to the base 2. The end of the telescopic membrane 32 away from the base 2 is connected to the outer wall of the equipment body 4.

[0028] The outer wall of the main body 4 is provided with a maintenance platform 3, and the base 2 is provided with rollers 11, which make rolling contact with the side wall of the slide rail 7.

[0029] In this embodiment, during the long-term full-load operation of the circuit breaker body 1, if the circuit breaker body 1 experiences high-temperature combustion faults such as overload overheating or internal short-circuit fire, the built-in fault sensing component of the circuit breaker body 1 can accurately detect the fire signal in real time and drive the electric push rod 17 to extend (this part is a mature existing electronic control technology, which will not be described in detail here). During the extension of the electric push rod 17, it can push the side plate 16 to move synchronously, thereby driving the transfer tube 15 to move towards the inside of the storage chamber 6 until the through hole 18 is fully inserted into the storage chamber 6 and connects the storage space. When the through hole 18 is connected to the internal cavity of the storage chamber 6, the pre-filled high-pressure gas inside the storage chamber 6 forms a pressurized delivery power, and the ultrafine dry powder extinguishing agent stored inside the storage chamber 6 can flow quickly into the transfer tube 15 through the through hole 18, and then flow into the spray tube 15. Pipe 14, and finally delivered to the interior of the rigid branch pipe 21 through nozzle 14. Since the storage chamber 6 adopts an internal pressure-sealed storage structure, under the continuous delivery of high-pressure gas, the mixture of ultrafine dry powder and high-pressure gas can form a stable jet impact force. The mixed extinguishing medium that enters the interior of the rigid branch pipe 21 can be partially delivered to the jet nozzle 12 through the rigid branch pipe 21. It is then diffused and sprayed over a wide area through the jet nozzle 12 to carry out fire suppression operations on the circuit breaker body 1 which is in a state of combustion failure. Using high-pressure airflow pipeline to deliver ultrafine dry powder for fire suppression operations can completely avoid the interference of outdoor natural wind on the diffusion of the extinguishing medium. It can accurately deliver the extinguishing medium to the open flame part and the smoldering fire area inside the circuit breaker body 1. Relying on ultrafine dry powder to quickly isolate the combustion oxygen and interrupt the combustion chain reaction, it can quickly suppress the spread of fire.

[0030] The mixture of ultrafine dry powder and high-pressure gas that enters the rigid branch pipe 21 is partially sprayed outward to complete the fire extinguishing operation, while the other part can push the pressing rod 19 to move outward, overcoming the elastic force of the pressing spring 20. During the outward movement of the pressing rod 19, it can rely on the universal wheel 33 to push the outer ring 25 to move, thereby driving the pressing member 30 to move closer to the moving member 28. After the end of the pressing member 30 comes into contact with the moving member 28, it can push the moving member 28 and the outer rod 29 to extend outward to the outside of the horizontal rail 27 along the preset inclined contact edge of the moving member 28. Based on the above linkage transmission principle, the outwardly extending outer rod 29 can form a locking engagement with the protrusion 26 to achieve forced locking and limiting of the rotating rod 5. By locking the rotating rod 5, the transmission path that drives the threaded rod 9 to rotate can be completely blocked, restricting any form of displacement movement of the circuit breaker body 1 from the power source. In the process of the circuit breaker body 1 catching fire and carrying out on-site emergency repair work. In the event of a fire, some inexperienced operators are prone to improper operation, such as unauthorized manipulation of the crank handle 8 to drive the rotating rod 5 to rotate, which in turn causes the circuit breaker body 1 to shift through the transmission structure. In the event of a fire, the rotating rod 5 is forcibly locked and limited, effectively preventing such human error from the source and avoiding accidental movement of the circuit breaker body 1 by repair personnel during fire handling. When a fire occurs, the circuit breaker body 1 is firmly locked and its displacement is restricted, effectively resisting the impact of internal arcing and high-temperature deformation, and preventing slippage or tilting of the circuit breaker body 1. This effectively protects the high and low voltage lines connected to the circuit breaker body 1 from being pulled and damaged, preventing secondary fires caused by line breakage, and maintaining a safe insulation distance between the circuit breaker body 1 and surrounding overhead conductors, electrical fittings, and installation frames for a long time, effectively avoiding external arc discharge, phase-to-phase short circuits, and other faults.

[0031] It should be noted that the telescopic diaphragm 32 is made of accordion-style weather-resistant rubber material, which can adaptively expand and contract with the displacement of the base 2. During the overall translation and movement of the circuit breaker body 1, the telescopic diaphragm 32 can adaptively expand and contract with the displacement of the circuit breaker body 1, forming a sealed and protective structure on the entire outer side of the rear cavity 35 throughout the process. This can effectively prevent foreign objects such as sand, dust, flocculent matter, rainwater impurities and other foreign objects in the outdoor open environment from entering the transmission and engagement parts of the threaded rod 9, avoiding the accumulation of impurities and jamming of the thread meshing surface from the source, effectively preventing mechanical failures such as rotation jamming and transmission jamming of the threaded rod 9, and ensuring that the entire hand-cranked translation transmission mechanism can operate stably and reliably in harsh outdoor working conditions for a long time.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
