Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, specifically a pole-mounted circuit breaker that is easy to adjust in terms of installation angle. Background Technology

[0002] As a key switching device in power distribution networks, pole-mounted circuit breakers are typically fixed to utility poles using mounting brackets and clamps to achieve control and protection functions for overhead lines. In existing technologies, the mounting brackets for pole-mounted circuit breakers are mostly rigid fixed structures, with the mounting base and clamp usually connected by direct welding or bolt fastening. The installation angle is fixed at the factory or during construction, making it impossible to adaptively adjust according to the actual tilt of the utility pole.

[0003] However, in actual operating environments, utility poles often tilt due to factors such as foundation settlement, external impacts, strong wind loads, or long-term uneven stress. When a utility pole tilts, if the existing rigid supports are still used for installation, it is difficult for workers to adjust the circuit breaker body to a horizontal position, causing the circuit breaker body to tilt along with the utility pole. The circuit breaker contains precision mechanical linkage components, contact systems, operating mechanisms, and arc-extinguishing chambers, among other key components. Its design operating condition is usually based on a horizontal installation posture to ensure the alignment accuracy and fit clearance between components. Tilted installation will disrupt the original alignment relationship of the internal mechanical linkage components, causing the transmission mechanism, crank arm, connecting rod, and other components to bear additional lateral stress, resulting in changes in the fit relationship between components. Long-term operation in this non-design posture will cause uneven stress, leading to deformation of the mechanism, accelerated wear, and even operational jamming, thereby affecting the circuit breaker's opening and closing performance and operational reliability. In severe cases, it may cause maloperation or failure to operate, posing a threat to the safe and stable operation of the distribution network.

[0004] Therefore, it is necessary to provide a pole-mounted circuit breaker with an adjustable installation angle, so that the circuit breaker body can still be installed horizontally when the utility pole is tilted, thereby ensuring the normal alignment and reliable operation of the internal mechanical components. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a pole-mounted circuit breaker that is easy to adjust in terms of installation angle.

[0006] The technical solution adopted by this utility model is: a pole-mounted circuit breaker that is easy to adjust the installation angle, comprising: a mounting base, wherein the mounting base includes a horizontal mounting plate, a vertical mounting plate, a clamping mechanism and an adjustment mechanism; The circuit breaker body is mounted on the mounting plate. The upper end of the vertical plate is hinged to one end of the mounting horizontal plate; The clamping mechanism is located on the outer sidewall of the vertical plate and is used to fix the mounting base to the utility pole. The adjustment mechanism includes a first connecting component, a second connecting component, and a double-ended screw. The first connecting component is fixedly connected to the inner side wall of the vertical plate, and the second connecting component is fixedly connected to the bottom wall of the mounting horizontal plate; The two ends of the double-ended screw are respectively screwed to the first connecting component and the second connecting component, and the angle between the vertical plate and the mounting horizontal plate is changed by rotating the double-ended screw.

[0007] Furthermore, the first connecting assembly includes a first "U"-shaped frame fixed to the inner side of the vertical plate, a first rotating shaft mounted on the first "U"-shaped frame, and a first "T" connector that rotatably engages with the first rotating shaft; The second connecting assembly includes a second "U"-shaped frame fixed to the bottom wall of the mounting plate, a second rotating shaft mounted on the second "U"-shaped frame, and a second "T"-shaped connector that rotatably engages with the second rotating shaft; Both the first "T" connector and the second "T" connector include a sleeve and a threaded sleeve integrally formed with the sleeve; The two ends of the double-ended screw have opposite threads, which are respectively threaded to the sleeves of the first "T" connector and the second "T" connector.

[0008] Furthermore, the double-ended screw has an operating part in the middle, the operating part including a hexagonal block and a handle fixedly connected to the hexagonal block.

[0009] Furthermore, mounting plates are provided on both side walls of the circuit breaker body extending outwards. The mounting plates and the mounting plate are provided with elongated holes, and fasteners pass through the elongated holes to fix the circuit breaker body to the mounting plate.

[0010] Furthermore, the clamping mechanism includes at least one set of clamping units, each set of clamping units including two parallel arc-shaped clamping strips arranged at intervals on the outside of the vertical plate and a locking member for locking the two arc-shaped clamping strips.

[0011] Furthermore, a level is provided on the upper surface of the mounting plate.

[0012] The beneficial effects of this utility model are: 1. By hinged between the vertical plate and the mounting horizontal plate, and with an adjustment mechanism consisting of a first connecting component, a second connecting component, and a double-ended screw between them, the angle of the mounting horizontal plate relative to the vertical plate can be adjusted. When the utility pole tilts due to foundation settlement, external forces, or long-term operation, workers can precisely change the angle between the vertical plate and the mounting horizontal plate by rotating the double-ended screw and utilizing the threaded engagement between its two ends and the first and second connecting components. This adjusts the circuit breaker body mounted on the mounting horizontal plate to a horizontal position, ensuring that the internal mechanical linkage components, contact system, and operating mechanism of the circuit breaker maintain the alignment accuracy and fit clearance under design conditions.

[0013] 2. This angle adjustment method effectively avoids problems such as uneven stress on the internal mechanism, changes in the fit relationship, deformation and wear, and operation jamming caused by the circuit breaker body being installed at an angle with the utility pole. It significantly improves the mechanical reliability and operational accuracy of the circuit breaker during long-term operation, reduces the risk of maloperation or failure to operate, and ensures the safe and stable operation of the power distribution network.

[0014] 3. A double-ended screw is used as the adjustment element. Simply rotating the screw allows the connecting components on both sides to move synchronously closer or further apart. Operation is simple, adjustment precision is high, and the threaded connection has a self-locking characteristic, ensuring stable and reliable angle position after adjustment without the need for additional locking devices. Simultaneously, the first and second connecting components are fixed to the inner side of the vertical plate and the bottom wall of the mounting horizontal plate, respectively, forming a reasonable spatial layout with the outer clamping mechanism. This results in a compact overall structure, a clear force transmission path, and facilitates on-site installation, commissioning, and subsequent maintenance.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0021] 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.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides a pole-mounted circuit breaker that is easy to adjust in terms of installation angle.

[0024] In this embodiment, refer to Figure 1-4 The pole-mounted circuit breaker, which is easy to install and has an adjustable angle, includes: a mounting base, which includes a horizontal mounting plate 1, a vertical mounting plate 2, a clamping mechanism 3, and an adjusting mechanism 4; Circuit breaker body 5, the circuit breaker body 5 is mounted on the mounting plate 1; The upper end of the vertical plate 2 is hinged to one end of the mounting horizontal plate; The clamping mechanism is located on the outer sidewall of the vertical plate and is used to fix the mounting base to the utility pole. The adjustment mechanism includes a first connecting component, a second connecting component, and a double-headed screw 6; The first connecting component is fixedly connected to the inner side wall of the vertical plate, and the second connecting component is fixedly connected to the bottom wall of the mounting horizontal plate; The two ends of the double-ended screw are respectively screwed to the first connecting component and the second connecting component, and the angle between the vertical plate and the mounting horizontal plate is changed by rotating the double-ended screw.

[0025] In the above technical solution, the mounting base consists of a horizontal mounting plate, a vertical mounting plate, a clamping mechanism, and an adjusting mechanism. The upper end of the vertical mounting plate is hinged to one end of the horizontal mounting plate, forming a pivotal connection that allows relative rotation. The clamping mechanism is located on the outer sidewall of the vertical mounting plate and is used to secure the entire mounting base to the utility pole. The adjusting mechanism consists of a first connecting component, a second connecting component, and a double-ended screw. The first connecting component is fixed to the inner sidewall of the vertical mounting plate, the second connecting component is fixed to the bottom wall of the horizontal mounting plate, and the two ends of the double-ended screw are respectively connected to the first and second connecting components in a rotating and threaded manner. When the double-ended screw is rotated, because the threads at both ends rotate in opposite directions, the distance between the first and second connecting components increases or decreases accordingly, thereby driving the horizontal mounting plate to rotate around its hinge point with the vertical mounting plate, changing the angle between the vertical mounting plate and the horizontal mounting plate.

[0026] Specifically, the first connecting component includes a first "U"-shaped frame 7 fixed to the inner side of the vertical plate, a first rotating shaft 8 mounted on the first "U"-shaped frame 7, and a first "T" connector 9 rotatably engaged with the first rotating shaft 8; The second connecting assembly includes a second "U"-shaped frame 10 fixed to the bottom wall of the mounting plate, a second rotating shaft 11 mounted on the second "U"-shaped frame, and a second "T"-shaped connector 12 rotatably engaged with the second rotating shaft 11; Both the first "T" connector and the second "T" connector include a sleeve 13 and a threaded sleeve 14 integrally formed with the sleeve; The two ends of the double-ended screw have opposite threads, which are respectively threaded to the sleeves of the first "T" connector and the second "T" connector.

[0027] In this embodiment, the first connecting assembly includes a first "U"-shaped frame fixed to the inner side of the vertical plate, a first rotating shaft mounted on the first "U"-shaped frame, and a first "T"-shaped connector rotatably engaged with the first rotating shaft; the second connecting assembly includes a second "U"-shaped frame fixed to the bottom wall of the mounting horizontal plate, a second rotating shaft mounted on the second "U"-shaped frame, and a second "T"-shaped connector rotatably engaged with the second rotating shaft. Both the first and second "T"-shaped connectors consist of a sleeve and a threaded sleeve integrally formed with the sleeve. The sleeve is respectively fitted onto the corresponding rotating shaft to achieve a rotatable engagement, and the threaded sleeve is respectively threaded to both ends of a double-ended screw.

[0028] The "U"-shaped bracket and rotating shaft provide stable rotational support for the "T" connector, allowing the two ends of the double-ended screw to self-adaptively rotate relative to the vertical plate and the mounting plate during rotational adjustment. This effectively releases the multi-directional displacement and rotational freedom generated during angle adjustment, preventing the threaded pair from bearing additional bending or torque and ensuring smooth adjustment. Simultaneously, the threaded engagement has a self-locking characteristic; once adjusted to the correct position, the thread friction between the double-ended screw and the threaded sleeve reliably maintains the current angle position, preventing loosening and backflow, and ensuring the circuit breaker body maintains a stable horizontal posture after adjustment.

[0029] Specifically, the double-ended screw has an operating part in the middle, which includes a hexagonal block 15 and a handle 16 fixedly connected to the hexagonal block.

[0030] In this embodiment, an operating part is provided in the middle of the double-ended screw. The operating part consists of a hexagonal block and a handle fixedly connected to the hexagonal block. The outer contour of the hexagonal block is hexagonal, which can be used with a standard wrench or socket tool; the handle protrudes from the surface of the hexagonal block, providing a manual grip and force application part.

[0031] Specifically, mounting plates 17 are provided on both sides of the circuit breaker body extending outward. The mounting plates 17 and the mounting plate are provided with elongated holes 18. Fasteners pass through the elongated holes to fix the circuit breaker body to the mounting plate.

[0032] In this embodiment, mounting plates extend outward from both side walls of the circuit breaker body. Elongated holes are correspondingly formed on the mounting plates and mounting horizontal plates. Fasteners pass through these elongated holes to fix the circuit breaker body to the mounting horizontal plate. The shape of the elongated holes allows the fasteners to move in a certain direction within the holes.

[0033] Specifically, the clamping mechanism includes at least one set of clamping units, and each set of clamping units includes two parallel arc-shaped clamping strips arranged at intervals on the outside of the vertical plate and a locking member for locking the two arc-shaped clamping strips.

[0034] In this embodiment, the clamping mechanism includes at least one set of clamping units. Each clamping unit consists of two parallel, spaced-apart arc-shaped clamps on the outside of the vertical plate and a locking member for locking the two arc-shaped clamps. The curvature of the two arc-shaped clamps is adapted to the outer periphery of the utility pole. The locking member (such as a bolt and nut assembly) tightens the free ends of the two clamps, causing the inner surface of the clamps to press against the outer wall of the utility pole.

[0035] Specifically, a level 19 is provided on the upper surface of the mounting plate.

[0036] In this embodiment, a level (such as a bubble level) is installed on the upper surface of the mounting plate. The reference plane of the level is parallel and attached to the upper surface of the mounting plate, and the position of the bubble inside it directly reflects the tilt state of the mounting plate relative to the horizontal plane.

[0037] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
