Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, specifically referring to an outdoor pole-mounted vacuum circuit breaker. Background Technology

[0002] Vacuum circuit breakers play a crucial role in power systems. They are mainly used to cut off and connect load current and short-circuit current in power lines. They can ensure the stability and safety of power transmission under various complex power conditions. They are widely used in power facilities such as substations and distribution networks. Whether it is the power supply network in cities or the distribution lines in rural areas, the stable operation of vacuum circuit breakers is indispensable. They are important equipment to ensure the continuity and reliability of power supply.

[0003] In the maintenance and installation of outdoor power facilities, existing outdoor vacuum circuit breakers are typically installed on utility poles. For example, some common outdoor pole-mounted vacuum circuit breakers have relatively fixed structural designs. During actual maintenance or installation, workers often face numerous inconveniences. Due to their high installation location and the inflexible nature of some structural designs, workers often encounter hard-to-reach parts when operating the circuit breaker. For instance, some terminals located deep within the side of the circuit breaker body or certain critical internal components require workers to frequently change positions due to the existing circuit breaker's structural layout and its connection to the utility pole. They may even need to use special tools or build additional auxiliary work platforms to barely manage to operate them. This not only significantly increases the labor intensity and working hours of workers and reduces work efficiency, but also increases the risks of working at height, easily leading to safety accidents due to operational difficulties.

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-9 :

[0045] Example 1:

[0046] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, including a circuit breaker body 1 and a support plate 2 for connecting the circuit breaker body 1 to a utility pole, and further including:

[0047] The protective mechanism 3 includes a protective housing 30 located on top of the support plate 2 and covering the circuit breaker body 1, and a heat dissipation assembly 4 located on the protective housing 30.

[0048] The fixing mechanism 5 includes a support platform 50 sleeved on the utility pole, a movable sleeve 51 sleeved on the utility pole and rotatably connected above the support platform 50, a turntable 52 for rotating the movable sleeve 51, a plurality of limiting components 6 for restricting the circumferential rotation of the movable sleeve 51 on the support platform 50, a fixing frame 53 located below the support plate 2 and connected to the fixing sleeve, a gripper assembly 7 for auxiliary fixing of the circuit breaker body 1, and a sliding lock assembly 8 located between the circuit breaker body 1 and the support plate 2.

[0049] The support plate 2 provides a stable support platform for the circuit breaker body 1, allowing it to be mounted on the utility pole. It also bears the weight of the circuit breaker body 1 and various forces generated during operation and environmental factors, ensuring the stability of the circuit breaker body 1's installation position on the utility pole and guaranteeing its normal operation. The support plate 2 is generally a rectangular plate structure, connected to the circuit breaker body 1 via a sliding lock assembly 8 and to the utility pole via a fixing mechanism 5.

[0050] The protective housing 30 covers the outside of the circuit breaker body 1, protecting it from harsh outdoor environments such as rain, sandstorms, and ultraviolet radiation. This prevents these factors from damaging the electrical performance and mechanical structure of the circuit breaker body 1, extending its service life. It also helps prevent accidental contact and improves safety. The protective housing 30 is generally a rectangular dome-shaped structure, adapted to the shape of the circuit breaker body 1 to fully cover it. Its size is slightly larger than the circuit breaker body 1, allowing sufficient space for installation and operation.

[0051] The heat dissipation component 4 dissipates the heat generated by the circuit breaker body 1 during operation in a timely manner, preventing the circuit breaker body 1 from being affected by excessive temperature, thus extending its electrical performance and service life.

[0052] The support platform 50 can be installed on the utility pole by welding, bolts, or other means, providing support and a base for rotational connection of the movable sleeve 51. By cooperating with the movable sleeve 51, the position of the support plate 2 can be adjusted and fixed, while bearing the weight and external force of the entire device, ensuring the stable installation of the device on the utility pole.

[0053] The movable sleeve 51 is fitted onto the utility pole and mates with the support platform 50. Rotation allows for adjustment of the position of the support plate 2. Once adjusted to the appropriate position, it is fixed in place with the support platform 50 and other components, ensuring the device remains stable on the utility pole. The movable sleeve 51 is generally a hollow cylindrical structure, rotatably connected to the support platform 50.

[0054] The turntable 52 is used to rotate the movable sleeve 51, providing operators with a convenient means of operation, allowing them to easily rotate the movable sleeve 51 and adjust the position of the device. The design of the turntable 52 saves effort and facilitates operation on utility poles, improving installation and maintenance efficiency. The turntable 52 is generally a circular disc structure and can be connected to the movable sleeve 51 through bushings, key connections, etc., ensuring that the rotation of the turntable 52 can drive the movable sleeve 51 to rotate synchronously.

[0055] The limiting component 6 is used to restrict the circumferential rotation of the movable sleeve 51 on the support platform 50 after the movable sleeve 51 is rotated to the appropriate position, so as to prevent the movable sleeve 51 from rotating unexpectedly due to external force or other reasons, and to ensure the stability of the device on the utility pole.

[0056] The fixed frame 53 connects the support plate 2 and the movable sleeve 51, transferring the weight and external force of the support plate 2 to the movable sleeve 51, and further to the support platform 50 and the utility pole, ensuring the stable installation of the support plate 2 on the utility pole. Simultaneously, the structural design of the fixed frame 53 must adapt to different installation environments and requirements to ensure the overall stability and reliability of the device. The fixed frame 53 is generally a triangular frame, a quadrilateral frame, or other frame structure, and can be connected to the support plate 2 and the movable sleeve 51 respectively through welding, bolting, or other methods.

[0057] The gripper assembly 7 provides auxiliary fixation for the circuit breaker body 1, enhancing the installation stability of the circuit breaker body 1 on the utility pole. The clamping ring 70 is fixed to the utility pole, and the clamping member 71 connects the support plate 2 to the clamping ring 70, preventing the support plate 2 from shifting or swaying in the horizontal direction, further ensuring the stable operation of the circuit breaker body 1.

[0058] The main function of the heat dissipation component 4 is to dissipate the heat generated by the circuit breaker body 1 during operation in a timely manner, ensuring that the circuit breaker body 1 is always within a suitable operating temperature range, thereby ensuring the stability of its electrical performance and the reliability of its mechanical structure, and extending the service life of the circuit breaker.

[0059] Example 2:

[0060] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] The protective housing 30 is formed by connecting two symmetrical first housings 300 and second housings 301. The support plate 2 is slidably connected to the first housing 300 and the second housing 301 respectively, and each of the first housing 300 and the second housing 301 is provided with a housing handle 302.

[0062] The protective housing 30 is formed by connecting two symmetrical first housings 300 and second housings 301. This symmetrical structure facilitates manufacturing, installation, and disassembly. During assembly, the circuit breaker body 1 can be enclosed from both sides, and the housing can be easily disassembled when maintenance or repair of the circuit breaker body 1 is required. The overall shape of the protective housing 30 is approximately a cuboid structure, with an internal space slightly larger than the circuit breaker body 1 to ensure complete enclosure and allow sufficient space for internal air circulation and heat dissipation. The first housing 300 and second housing 301 are generally connected by bolts or snap-fit ​​joints distributed along the edges to achieve a tight connection, forming a complete protective space.

[0063] The housing handle 302 facilitates the opening, closing, installation, and disassembly of the protective housing 30 by operators. When maintenance, repair, or debugging of the circuit breaker body 1 is required, operators can easily separate or close the two housings by gripping the housing handle 302 and applying appropriate force, improving operational convenience and efficiency while reducing operation time and labor intensity. The housing handle 302 is generally a rod-shaped or block-shaped structure and can be installed on the outer walls of the first housing 300 and the second housing 301 respectively by welding, bolting, or other methods.

[0064] Example 3:

[0065] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] The heat dissipation component 4 includes:

[0067] Solar panels 40 are installed on top of the first housing 300 and the second housing 301;

[0068] A storage battery 41 is disposed on the side wall of the first housing 300, and the storage battery 41 is electrically connected to the solar panel 40;

[0069] A cooling fan 42 is disposed on the side wall of the first housing 300. The cooling fan 42 is electrically connected to the battery 41, and multiple heat dissipation slots 43 are provided on both the first housing 300 and the second housing 301.

[0070] The solar panel 40 utilizes the photoelectric effect to convert solar energy into electrical energy, providing power for the entire heat dissipation assembly 4. In outdoor environments, no additional power supply is required; it can continuously generate electricity relying on sunlight, achieving energy self-sufficiency and improving the energy efficiency, environmental friendliness, and outdoor adaptability of the equipment. The solar panel 40 is generally a flat structure that matches the top shape of the protective housing 30 and can be fixed to the top of the protective housing 30 by bolts, clips, or glue.

[0071] The storage battery 41 stores the electrical energy generated by the solar panel 40, providing a stable power output to the cooling fan 42. It ensures the cooling fan 42 operates normally even when there is insufficient sunlight or no sunlight, guaranteeing uninterrupted heat dissipation for the circuit breaker body 1 and ensuring stable operation of the equipment under various weather conditions, thus improving the reliability and adaptability of the entire system. The storage battery 41 is connected to the solar panel 40 via wires and fixed to the side wall of the first housing 300 via bolts.

[0072] The cooling fan 42 is driven by a motor to rotate its blades at high speed, creating a forced airflow within the protective housing 30. This accelerates airflow and quickly removes the heat generated during the operation of the circuit breaker body 1, improving heat dissipation efficiency. The motor of the cooling fan 42 can be connected to the battery 41 via wires. The cooling fan 42 as a whole is fixed to the side wall of the first housing 300 by bolts, clips, or brackets.

[0073] The heat dissipation slots 43 serve as channels for natural ventilation. When the cooling fan 42 is not running or is assisting the cooling fan 42 in heat dissipation, the natural convection principle of air allows for the exchange of air inside and outside the protective housing 30, carrying away some heat. The heat dissipation slots 43 are generally rectangular strips, evenly distributed on the side walls of the first housing 300 and the second housing 301.

[0074] Example 4:

[0075] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] The support platform 50 includes:

[0077] The inner ring 500 is fixed to the utility pole and abuts against the bottom of the movable sleeve 51;

[0078] The outer ring 501 is formed by the joining of two mutually symmetrical semi-circular ring plates, and the outer ring 501 is located above the inner ring 500 and is rotatably connected to the movable sleeve 51.

[0079] Multiple connecting rods 502 are circumferentially connected between the outer ring 501 and the inner ring 500 along the central axis of the movable sleeve 51.

[0080] The inner ring 500 is used to firmly fix the support platform 50 to the utility pole, providing a stable foundation support point for the entire fixing mechanism 5, bearing the weight of all components above and external forces, and evenly transmitting these forces to the utility pole. Simultaneously, the contact between the inner ring 500 and the bottom of the movable sleeve 51 ensures the stability of the movable sleeve 51. The inner ring 500 is generally a circular ring-shaped structure and can be fixed to the utility pole by means of clamps, bolts, etc.

[0081] The outer ring 501 provides a horizontal rotational support platform for the movable sleeve 51, allowing the movable sleeve 51 to rotate flexibly around its circumference, thus facilitating the adjustment of the horizontal angle position of the circuit breaker body 1. The outer ring 501 is generally a ring structure formed by bolts, welding, or other methods connecting two symmetrical semi-circular ring plates. Simultaneously, the outer ring 501 is connected to the inner ring 500 via a connecting rod 502, together forming the overall frame structure of the support platform 50. This enhances the stability and load-bearing capacity of the support platform 50, ensuring structural integrity under various external forces and providing reliable support for the components above. The outer ring 501 and the movable sleeve 51 can be connected via bearings or other rotating connecting components. The inner ring of the bearing is fixedly connected to the outer ring 501, and the outer ring mates with a corresponding structure at the bottom of the movable sleeve 51, allowing the movable sleeve 51 to rotate flexibly on the bearing.

[0082] Connecting rod 502 connects inner ring 500 and outer ring 501, combining them into a stable support platform 50 frame structure, enhancing the overall strength and stability of the support platform 50. Connecting rod 502 is generally a long, straight rod structure, evenly distributed circumferentially along the central axis of movable sleeve 51, connecting the outer ring 501 and inner ring 500. It can be connected to the inner ring 500 and outer ring 501 by welding or bolts.

[0083] Example 5:

[0084] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0085] The bottom of the movable sleeve 51 is provided with a fixed ring 54 that rotates with the outer ring 501, and the limiting component 6 includes:

[0086] Mounting block 60 is located at the top of outer ring 501;

[0087] The mounting groove 61 is provided on the side of the mounting block 60 facing the movable sleeve 51. The mounting groove 61 is provided with a positioning block 64, and an elastic reset member 62 is provided between the positioning block 64 and the mounting groove 61.

[0088] The limiting screw 63 passes through the positioning block 64 and is threaded to the retaining ring 54.

[0089] Mounting block 60 serves as the basic mounting structure for the limiting component 6, providing a fixed mounting position for the entire limiting component 6. This allows it to be stably positioned on top of the outer ring 501 of the support platform 50, and then cooperates with the fixing ring 54 on the movable sleeve 51 to limit the circumferential rotation of the movable sleeve 51 on the support platform 50. Mounting block 60 is generally a rectangular block structure and can be fixedly connected to the outer ring 501 of the support platform 50 by welding, bolting, or other methods.

[0090] The mounting groove 61 is formed on the mounting block 60, mainly to accommodate the positioning block 64 and provide a limited space for the positioning block 64 to slide or be positioned within the mounting groove 61 according to design requirements. This allows it to cooperate with the fixing ring 54 to limit and release the movable sleeve 51. Simultaneously, the mounting groove 61 also provides a mounting position for the elastic reset member 62, enabling it to function as a reset spring within a suitable space, ensuring the flexibility and reliability of the limiting assembly 6. The mounting groove 61 is generally a rectangular or other shaped groove structure, integrally formed with the mounting block 60.

[0091] In its normal state, the positioning block 64, through the elastic force of the elastic reset member 62, protrudes a portion of itself from the mounting groove 61, cooperating with the corresponding limiting structure on the fixing ring 54 to restrict the circumferential rotation of the movable sleeve 51, ensuring the device remains stable after being adjusted in position. The positioning block 64 is generally a block-shaped structure whose shape matches the mounting groove 61, allowing it to slide within the groove. It has an internal threaded hole that mates with the limiting screw 63. Within the mounting groove 61, the positioning block 64 is connected to the groove wall via the elastic reset member 62, allowing it to slide in a specific direction within the groove.

[0092] The elastic reset element 62 plays a crucial role in providing elastic force in the limiting assembly 6. The direction of its elastic force ensures that the positioning block 64 remains in a limited position, protruding from the mounting groove 61 and engaging with the fixing ring 54, under normal conditions. When an external force is applied to the positioning block 64, causing it to retract into the mounting groove 61 against the elastic force, the elastic reset element 62 is compressed and stores elastic potential energy. Once the external force disappears, the elastic reset element 62 releases its elastic potential energy, pushing the positioning block 64 back to its original limited position, restoring the limitation on the movable sleeve 51. This ensures that the limiting assembly 6 can automatically and reliably perform the cycle of limiting and releasing, improving the convenience and stability of the device operation. One end of the elastic reset element 62 is fixedly connected to the wall of the mounting groove 61 by means of hooks, bends, or welding, while the other end is connected to the positioning block 64 using a suitable connection method.

[0093] The limiting screw 63 passes through the positioning block 64 and is threaded to the fixing ring 54. When the limiting screw 63 is tightened, an additional axial pressure is applied to the positioning block 64, making the limiting fit between the positioning block 64 and the fixing ring 54 tighter. This prevents the positioning block 64 and the fixing ring 54 from loosening or separating when subjected to large external forces, thereby improving the firmness of the limiting of the movable sleeve 51 and ensuring the stability of the device during normal operation.

[0094] Example 6:

[0095] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0096] The gripper assembly 7 includes:

[0097] The clamping ring 70 is fixedly attached to the utility pole;

[0098] Clamping element 71 is used to fix the support plate 2 and clamping ring 70.

[0099] The clamping ring 70 is fitted onto the utility pole and tightly connected to it, providing a stable fixing base and force point for the clamping member 71. This allows the clamping member 71 to effectively apply clamping force to the support plate 2, thereby achieving auxiliary fixation of the circuit breaker body 1. The clamping ring 70 is generally a circular ring structure and can be connected to the utility pole by bolts, clamping hoops, or other means to form a solid whole. The clamping member 71 is fitted onto the clamping ring 70 and connected to the support plate 2.

[0100] Example 7:

[0101] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0102] The clamping member 71 includes:

[0103] The clamping claw 710 is formed by the docking of two symmetrical structures, and the clamping claw 710 is rotatably connected to the clamping ring 70;

[0104] The first slide block 711 is located at one end of the clamping claw 710, and the support plate 2 has a first slide rail on the side near the utility pole for the first slide block 711 to slide.

[0105] The clamping jaw 710 interacts directly with the clamping ring 70 and the support plate 2, clamping and releasing the support plate 2 through its opening and closing action. In the clamped state, sufficient clamping force is applied to the support plate 2 to prevent horizontal displacement or swaying, thus ensuring the stable installation of the circuit breaker body 1. When maintenance, repair, or adjustment of the circuit breaker body 1 is required, the support plate 2 and the circuit breaker body 1 can be easily moved or operated by releasing the clamping jaw 710, improving the convenience and flexibility of equipment use. The clamping jaw 710 is formed by the mating of two symmetrical structures, each typically a curved sheet of metal. They are rotatably connected at the mating point by a pin, hinge, or other rotating connecting component, allowing the two symmetrical structures to rotate relative to each other around the connection point, thus achieving the clamping and releasing action.

[0106] The first slide block 711 provides sliding support for the clamping claw 710 on the support plate 2, allowing the clamping claw 710 to slide smoothly along the first slide rail of the support plate 2 in the horizontal direction, thereby realizing clamping and releasing operations at different positions of the support plate 2. The first slide block 711 is generally a rectangular block structure. The first slide block 711 and the clamping claw 710 are connected by welding, bolting, or integral molding to form an integral structure, ensuring that the first slide block 711 can move with the clamping claw 710 when it opens and closes, and transmit the force to the slide rail. It is connected to the first slide rail on the support plate 2 through a sliding fit. Generally, a groove or protrusion structure matching the slide rail is provided on the side of the slide block near the support plate 2, so that the slide block can slide smoothly on the slide rail.

[0107] Example 8:

[0108] This embodiment provides an outdoor pole-mounted vacuum circuit breaker, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0109] The slide lock assembly 8 includes:

[0110] The second slide block 80 is located at the bottom of the circuit breaker body 1. The top of the support plate 2 is provided with a second slide rail that cooperates with the second slide block 80, and the circuit breaker body 1 is provided with a body handle 81 for driving the second slide block 80 to move.

[0111] A locking screw hole 82 is provided on one side of the support plate 2 and connected to the second slide rail. The second slide block 80 is provided with a threaded hole that matches the locking screw hole 82, and a locking bolt 83 connected to the threaded hole is provided in the locking screw hole 82.

[0112] The second slide block 80, as a key component in the sliding lock assembly 8, cooperates with the second slide rail to achieve the sliding function.
