[0002] A pole-mounted circuit breaker is a switchgear installed on a power line pole, mainly used to quickly cut off the circuit to protect the power system from faults such as short circuits and overloads. Pole-mounted circuit breakers not only provide fault protection, but also facilitate manual or remote control operation to achieve effective management of the power system. When a short circuit, overload or other fault occurs in the power system, the pole-mounted circuit breaker can quickly cut off the current, thereby protecting the transmission line and electrical equipment, and preventing equipment damage and safety accidents such as fire. During maintenance or overhaul, the pole-mounted circuit breaker can isolate the equipment from the power grid to ensure the safety of the staff.

The patent has a simple structure, a novel design, and is easy to operate. It solves the problem that when there is no operating power supply, only manual opening operation can be performed and manual closing operation cannot be performed, reduces the cumbersomeness of power transmission, and enables the pole-mounted circuit breaker to transmit power when there is no operating power supply, so that the use occasions and conditions of the pole-mounted circuit breaker are less restricted, and has a good market promotion prospect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention realizes that when the electric pole at the location vibrates, the upper conductive rod and the lower conductive rod can slide adaptively relative to the arc extinguishing chamber, thereby reducing the influence of the vibration, preventing the wires from being pulled and preventing the upper and lower contact plates from being misaligned and disconnected, thereby reducing the probability of circuit failure; specifically, when the electric pole vibrates, the arc extinguishing chamber will follow the vibration.

[0021] (2) The present invention enables the upper conductive rod to slide relative to the arc extinguishing chamber through the size and structure design of the sliding plate and the limit ring. At the same time, through the cooperation of the first elastic rubber ring, the sealing performance of the upper conductive rod can be guaranteed when it moves relatively. At the same time, through the structural design of the first bellows, the sealing performance of the lower conductive rod can be guaranteed when it moves relatively, thereby comprehensively improving the sealing of the arc extinguishing chamber and ensuring the normal operation of the arc extinguishing chamber even when the electric pole vibrates.

[0022] (3) The present invention cooperates with the control rod and the slide groove mechanism.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0035] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items. Example

[0036] like Figure 1 to Figure 9 As shown, a shockproof column mounted circuit breaker comprises a mechanism box 100, a plurality of mounting holes 110 are provided on the top of the mechanism box 100, an arc extinguishing chamber 200 is fixedly mounted on the mounting holes 110; an upper conductive rod 300 is movably mounted on the top of the arc extinguishing chamber 200, a sliding groove tube 210 is connected to the side wall of the arc extinguishing chamber 200, and a lower conductive rod 400 is slidably connected to the sliding groove tube 210;

[0037] The lower conductive rod 400 is fixedly provided with a conductive ring 410 at one end located inside the arc extinguishing chamber 200, a lower contact rod 420 is slidably connected inside the conductive ring 410, a lower contact plate 430 is fixedly connected to the upper end of the lower contact rod 420, and an upper conductive rod 300 is fixedly connected to one end located inside the arc extinguishing chamber 200;

[0038] The lower end of the lower touch rod 420 is connected to a control rod 800 . A driving mechanism 600 is disposed below the control rod 800 . The driving mechanism 600 is used to drive the vertical displacement of the control rod 800 .

[0039] The present invention drives the vertical displacement of the control rod 800 through the driving mechanism 600, thereby driving the lower contact rod 420 to rise or fall, thereby realizing the connection and disconnection of the upper contact plate 320 and the lower contact plate 430, thereby realizing the passage and the circuit breaking; the upper conductive rod 300 is movably installed on the top of the arc extinguishing chamber and the lower conductive rod 400 is slidably connected in the sliding groove tube 210, so that when the electric pole at the location vibrates, the upper conductive rod 300 and the lower conductive rod 400 can adaptively slide relative to the arc extinguishing chamber 200, thereby reducing the impact of the vibration, preventing the wires from being pulled and preventing the upper contact plate 320 and the lower contact plate 430 from being misaligned and disconnected, thereby reducing the probability of circuit failure, which will be described in detail later.

[0040] It is worth noting that the driving mechanism 600 is an existing mature technology, for example, through a connecting rod structure design, etc., which will be described in detail later.

[0041] Furthermore, a limit ring 230 is provided on the inner wall of the arc extinguishing chamber 200 and extends inward; a first elastic rubber ring 500 is fixedly connected to the top opening of the arc extinguishing chamber 200, and the upper conductive rod 300 is movably abutted against the inner side of the first elastic rubber ring 500; a sliding plate 310 is fixedly provided on the outer wall of the upper conductive rod 300, and a sliding groove is formed between the first elastic rubber ring 500 and the limit ring 230, and the sliding plate 310 is located in the sliding groove and is slidably connected to the sliding groove.

[0042] Specifically, when the electric pole vibrates, the arc extinguishing chamber 200 will vibrate accordingly. At this time, since the sliding plate 310 is located in the sliding groove and is slidably connected to the sliding groove, the upper conductive rod 300 will compress the first elastic rubber ring 500, causing the upper conductive rod 300 and the sliding plate 310 to slide relative to each other in the sliding groove, thereby reducing the vibration amplitude of the upper conductive rod 300; at the same time, during the vibration process, the lower conductive rod 400 slides relative to the sliding groove tube 210 in the sliding groove tube 210, thereby reducing the vibration amplitude of the lower conductive rod 400 and the lower contact rod 420, thereby comprehensively reducing the vibration amplitude of the upper conductive rod 300 and the lower conductive rod 400, preventing the wires from being pulled and damaged, and preventing the upper contact plate 320 and the lower contact plate 430 from being misaligned and disconnected.

[0043] Furthermore, the outer diameter of the sliding plate 310 is smaller than the inner diameter of the arc extinguishing chamber 200, and the outer diameter of the sliding plate 310 is larger than the inner diameter of the limiting ring 230; the outer diameter of the upper conductive rod 300 is smaller than the inner diameter of the limiting ring 230; the contact surface of the upper touch plate 320 is a conical concave structure, and the contact surface of the lower touch plate 430 is a conical convex structure, and the contact surface of the lower touch plate 430 matches the contact surface of the upper touch plate 320.

[0044] By designing the contact surface of the upper touch plate 320 as a conical concave structure and the contact surface of the lower touch plate 430 as a conical convex structure, the connection between the upper touch plate 320 and the lower touch plate 430 can be more stable when the upper conductive rod 300, the lower touch rod 420 and the arc extinguishing chamber 200 move relative to each other, and the probability of relative sliding between the upper touch plate 320 and the lower touch plate 430 is reduced, thereby avoiding the generation of electric arcs and wear.

[0045] Furthermore, one end of the sliding groove tube 210 located inside the arc extinguishing chamber 200 is fixedly connected to a first bellows 440 , and one end of the first bellows 440 away from the sliding groove tube 210 is fixedly connected to a sealing ring 441 , and the inner side of the sealing ring 441 is fixedly connected to the outer wall of the lower conductive rod 400 .

[0046] The present invention enables the upper conductive rod 300 to slide relative to the arc extinguishing chamber 200 through the size and structural design of the sliding plate 310 and the limiting ring 230. At the same time, through the cooperation of the first elastic rubber ring 500, the sealing performance of the upper conductive rod 300 can be guaranteed when it slides relatively. At the same time, through the structural design of the first bellows 440, the sealing performance of the lower conductive rod 400 can be guaranteed when it slides relatively, thereby comprehensively improving the sealing performance of the arc extinguishing chamber 200, so that the normal operation of the arc extinguishing chamber 200 can be guaranteed even when the electric pole vibrates.

[0047] Furthermore, a second bellows 450 is provided at the bottom of the arc extinguishing chamber 200, one end of the second bellows 450 is a closed end and the other end is an open end; the closed end of the second bellows 450 is fixedly connected to the lower touch rod 420, and the open end of the second bellows 450 is sealed and fixedly connected to a second elastic rubber ring 510; the outer wall of the second elastic rubber ring 510 is fixedly connected to the inner wall of the arc extinguishing chamber 200, and the inner bottom end of the second bellows 450 is fixedly connected to the control rod 800; the side wall of the control rod 800 movably abuts against the inner side of the second elastic rubber ring 510.

[0048] In the present invention, when the electric pole vibrates, the control rod 800 will also relatively compress the second elastic rubber ring 510, thereby reducing the vibration amplitude of the control rod 800. The second bellows 450 and the second elastic rubber ring 510 ensure the sealing of the bottom end of the arc extinguishing chamber 200.

[0049] It is worth noting that the first elastic rubber ring 500 and the second elastic rubber ring 510 are both made of insulating elastic materials and can be compressed. As for the specific materials, they can be selected according to conventional methods and are not further limited here.

[0050] Furthermore, the driving mechanism 600 includes a first rotating shaft 610, both ends of which are rotatably connected to the interior of the mechanism box 100, a plurality of curved rods 620 are fixedly connected to the first rotating shaft 610, one end of the curved rod 620 movably abuts against the lower end of the control rod 800, and the other end of the curved rod 620 is hinged with a connecting rod 630; one end of the connecting rod 630 away from the curved rod 620 is fixedly connected to the side wall of the second rotating shaft 640, and the second rotating shaft 640 is rotatably connected to the mechanism box 100; one end of the second rotating shaft 640 is fixedly connected to a control handle, and the control handle is located outside the mechanism box 100.

[0051] Furthermore, an energy storage device 700 is installed inside the mechanism box 100 , and the energy storage device 700 is used to control the rotation of the second rotating shaft 640 .

[0052] The driving mechanism of the present invention can control the rotation of the second rotating shaft 640 through the control handle, thereby driving the connecting rod 630 to push or pull the curved rod 620, so that the other end of the curved rod 620 can rise or fall, and the rise or fall of the control rod 800 is achieved by abutting against the control rod 800, which is the prior art; at the same time, the energy storage device 700 can drive the second rotating shaft 640 to rotate by means of spring energy storage, etc., which is also the prior art and will not be described in detail here.

[0053] Furthermore, an abutment plate 820 is fixedly provided at the lower end of the control rod 800, and a plurality of sliding rods 840 are evenly provided around the top of the abutment plate 820; the plurality of sliding rods 840 are slidably connected to a sliding ring block 830, and a return spring 850 is sleeved on the sliding rod 840, and the two ends of the return spring 850 are respectively fixedly connected to the sliding ring block 830 and the abutment plate 820; and a limit block 860 is fixedly provided at one end of the sliding rod 840 away from the abutment plate 820.

[0054] Furthermore, a slide groove mechanism 900 is provided below the mounting hole 110, and the slide groove mechanism 900 includes a through pipe 910, and a fixing ring block 930 is fixedly provided on the periphery of the upper end of the through pipe 910, and the fixing ring block 930 is fixedly connected to the bottom of the mounting hole 110 by bolts; a limiting ring block 920 is fixedly provided on the periphery of the lower end of the through pipe 910, and a limiting slide groove 921 is provided on the inner side wall of the limiting ring block 920, and the sliding ring block 830 is located in the limiting slide groove 921 and is slidably connected to the limiting slide groove 921.

[0055] The present invention cooperates with the control rod 800 and the slide groove mechanism 900. When the electric pole vibrates, the sliding ring block 830 will slide relatively in the limiting slide groove 921. Therefore, through the cooperation of the slide groove mechanism 900, the control rod 800 and the sliding ring block 830 can stably move relative to each other, thereby improving the connection stability between the upper touch plate 320 and the lower touch plate 430. At the same time, due to the structural design of the movable abutment between the abutment plate 820 of the control rod 800 and the curved rod 620 of the driving mechanism 600, the driving mechanism 600 can still stably abut the control rod 800 when the control rod 800 and the sliding ring block 830 move relative to each other, thereby further improving the connection stability between the upper touch plate 320 and the lower touch plate 430.

[0056] It is worth mentioning that when the bent rod 62 of the driving mechanism 600 rotates the abutment disk 820 to move upward, the reset spring 850 is compressed, and the control rod 800 moves upward, thereby controlling the lower contact rod 420 to move upward to achieve circuit closure; when the bent rod 62 of the driving mechanism 600 rotates in the opposite direction, gravity and the reset spring 850 are reset to control the lower contact rod 420 to move quickly downward to achieve a quick circuit disconnection operation.

[0057] Furthermore, a mounting plate 220 is fixedly provided on the periphery of the bottom of the arc extinguishing chamber 200 , and the mounting plate 220 is fixedly connected to the periphery of the top of the mounting hole 110 by bolts.

[0058] It is worth noting that the mechanism box 100 is fixed to the electric pole by a bracket, which is a conventional setting and is therefore not shown in the drawings.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
