Description

Technical Field

[0001] This utility model relates to the field of circuit breakers, and in particular to a primary and secondary integrated pole-mounted circuit breaker that is easy to maintain. Background Technology

[0002] A primary and secondary integrated pole-mounted circuit breaker is a complete circuit breaker device that is installed on a utility pole using a mounting bracket. Generally, the installation of a pole-mounted circuit breaker requires the assistance of an aerial work platform.

[0003] The prior art patent application with publication number CN223123814U uses a self-locking component to achieve one-way locking of the mounting bracket as it moves downward on the utility pole. When construction workers climb the pole and lift the mounting bracket and the circuit breaker body, the downward locking of the mounting bracket ensures that the weight of the mounting bracket and the circuit breaker body does not always act on the construction workers, reducing the difficulty of installing this type of primary and secondary integrated pole-mounted circuit breaker and reducing the risks during construction.

[0004] However, current circuit breakers are operated by using a combination of self-locking components and support frames during installation or removal. In contrast, the self-locking components and support frames used now are operated independently. This means that the circuit breaker is prone to tilting when operating due to the independent operation of the mechanism.

[0005] Therefore, it is necessary to provide a convenient primary and secondary integrated pole-mounted circuit breaker to solve the above-mentioned technical problems. Summary of the Invention

[0006] This utility model provides a primary and secondary integrated pole-mounted circuit breaker that is easy to maintain. It solves the problem that the circuit breaker tends to tilt when the self-locking components and support frames used in the current system are operated separately.

[0042] Two rolling components 4 are respectively disposed on both sides inside the fixed frame 3. Each rolling component 4 includes two fixed blocks 41, a rolling wheel 42, a rotating rod 43, a circular limiting block 44, and a limiting bolt 45. The two fixed blocks 41 are symmetrically connected to the inner wall of the fixed frame 3. The rolling wheel 42 is disposed between the two fixed blocks 41. The rotating rod 43 is connected to one end of the rolling wheel 42. The circular limiting block 44 is connected to one end of the rotating rod 43. The limiting bolt 45 is disposed inside the circular limiting block 44.

[0043] The bracket 5 is connected to one end of the limiting bolt 45;

[0044] The fixing component 8 is disposed below the fixing frame 3;

[0045] The connecting component 6 is disposed on one side of the fixing component 8.

[0046] The fixing component 8 includes two fixing hoops 81, a fixing member 82, and a fixing frame 83. The fixing member 82 is disposed between the two fixing hoops 81, and the fixing frame 83 is connected between one of the fixing hoops 81 and the fixing frame 3.

[0047] One end of the roller 42 is rotatably connected to one side of one of the fixed blocks 41 via a rotating shaft, and the other end is connected to one end of the rotating rod 43. One end of the rotating tube 43 passes through another fixed block 41 and the fixed frame 3 and extends to the outside of the fixed frame 3. Multiple limiting through holes adapted to the limiting bolts 45 are opened on the surface of the circular limiting block 44. The fixed frame 3 is connected by two U-shaped fixed frames via a rotating shaft. The use of the limiting groove 72 and the limiting block 73 can limit the movement of the rotating rod 61 and the threaded bolt 62.

[0048] The connecting assembly 6 includes a rotating rod 61, a threaded bolt 62, a movable sleeve 63, and two stops 64. The threaded bolt 62 is connected to one end of the rotating rod 61, the movable sleeve 63 is fitted onto the surface of the rotating rod 61, and the two stops 64 are both connected to the surface of the rotating rod 61 and located on both sides of the movable sleeve 63.

[0049] A limiting component 7 is provided below the fixed frame 3 and on one side of the connecting component 6. The limiting component 7 includes a rectangular plate 71, a limiting groove 72, a limiting block 73, and a connecting bracket 74.

[0050] Fasteners 9 are provided on one side of the fixed frame 3.

[0051] The working principle of the primary and secondary integrated pole-mounted circuit breaker provided by this utility model, which is convenient for maintenance, is as follows:

[0052] In use, first, the fixing frame 3 is placed on the pole and then the fixing frame 3 is tightened with the fastener 9. At the same time, when the fixing frame 3 is tightened, the rolling wheel 42 is pushed to contact the surface of the pole. After the fixing frame 3 is fixed, the two fixing hoops 81 are placed on the surface of the pole and the fixing parts 82 are used to fix one side of the two fixing hoops 81.

[0053] After installing the fixed frame 3 and the two fixed clamps 81, the circuit breaker body 1 is moved by pushing it. When the circuit breaker body 1 moves up and down, the fixed frame 3 is moved by the bracket 2. When the fixed frame 3 moves, the internal rollers 42 rotate. When one of the rollers 42 rotates, the circular limit block 44 rotates by the rotating rod 43. When the circuit breaker body 1 is fixed on the pole, the threaded bolt 62 is rotated into the two fixed clamps 81 by rotating the rotating rod 61. When the rotating rod 61 pushes the threaded bolt 62 into the two fixed clamps 81, the limit bolt 45 is pushed into the limit hole on the surface of the circular limit block 44 by the bracket 5. When the rotating rod 61 pushes, the limit block 73 moves into the limit groove 72 through the movable sleeve 63 and the connecting block until the threaded bolt 62 is fixed on the other side of the two fixed clamps 81 and the roller 42 is self-locked.
