Description

Technical Field

[0001] This utility model belongs to the technical field of pole-mounted circuit breakers, specifically relating to a spring-operated pole-mounted circuit breaker. Background Technology

[0002] With the rapid development of the economy and the continuous increase in power supply, in order to improve the power supply reliability of the power grid and meet the increasing dependence of various customers on electricity, it is often necessary to install pole-mounted circuit breakers on the interconnection, segment, and straight lines of the power grid. Existing pole-mounted circuit breakers need to provide the power for opening and closing operations through internal spring operating mechanisms to ensure that the pole-mounted circuit breakers can complete the opening and closing actions quickly and reliably.

[0003] Currently, in order to install pole-mounted circuit breakers on utility poles, it is often necessary to carry an additional support frame. Workers need to climb the utility pole to carry out the installation. Since the pole-mounted circuit breaker and the support frame are separate, workers need to carry both when performing the installation work. When installing the support frame onto the utility pole, the pole-mounted circuit breaker carried by the worker can easily restrict the worker's movements, increasing the difficulty of installing the pole-mounted circuit breaker.

[0004] Therefore, to address the issue that existing pole-mounted circuit breakers require additional support frames to be installed on utility poles, and that the presence of the pole-mounted circuit breaker can restrict worker movement during support frame installation, a spring-operated pole-mounted circuit breaker with a folding bracket can be designed. Utility Model Content

The bottom end of the sliding support frame is provided with a rotating support frame. The top of the rotating support frame is fixedly connected to a rotating shaft, which is rotatably inserted into the sliding support frame.

[0007] Preferably, the first slider moves along the first T-shaped groove, thereby driving the sliding support frame fixedly connected to the first slider to move. The sliding support frame drives the rotating support frame to move backward, avoiding the rotating support frame used for fixing being too close to the pole-mounted circuit breaker body. The rotating support frame is driven to rotate by the rotating shaft. One end of the rotating support frame is a semi-arc structure that matches the outer diameter of the utility pole. It can be fixed by bolts and nuts through another semi-arc installation structure.

[0008] Preferably, a slot is provided in the T-shaped slide groove, and a buckle that matches the slot is fixedly connected to the front side of the slider.

[0009] Preferably, the sliding support frame has a first anchor hole that penetrates through the sliding support frame, and the rotating support frame has a second anchor hole that penetrates through the rotating support frame.

[0010] As a preferred embodiment, a No. 1 protective cover is installed on the top of the pole-mounted circuit breaker body, and a No. 1 mounting base is fixedly connected to both the left and right sides of the No. 1 protective cover. A No. 2 protective cover is slidably connected to the top of the No. 1 protective cover.

[0011] As a preferred embodiment, the top of the No. 1 protective cover is provided with two No. 2 T-shaped sliding grooves that are opposite to each other on the left and right sides. A No. 2 slider is slidably connected in the No. 2 T-shaped sliding groove, and the No. 2 slider is fixedly connected to the bottom of the No. 2 protective cover.

[0014] The beneficial effects of this utility model are:

[0015] 1. By adding a sliding mounting bracket and a rotating mounting bracket to the bottom of the pole-mounted circuit breaker, the mounting bracket and the circuit breaker are integrated. Only the pole-mounted circuit breaker body needs to be carried to move the integrated mounting bracket together. When installing the mounting bracket on the utility pole, there is no need to worry about the pole-mounted circuit breaker falling due to excessive movement by the workers, which reduces the difficulty of installation.

[0016] 2. Multiple protective covers are installed on the pole-mounted circuit breaker. These covers protect the circuit breaker from damage caused by flying birds or squirrels, thus extending its service life. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-7This utility model provides an embodiment: a spring-operated pole-mounted circuit breaker, including a pole-mounted circuit breaker body 1; it also includes a sliding support frame 2 and a rotating support frame 3. The sliding support frame 2 is provided below the pole-mounted circuit breaker body 1. The bottom end of the pole-mounted circuit breaker body 1 has a first T-shaped groove 4 with left and right opposite sides. A first slider 5 is movably connected in the first T-shaped groove 4. The first slider 5 is fixedly connected to the top of the sliding support frame 2. The bottom end of the sliding support frame 2 is provided with a rotating support frame 3. The top of the rotating support frame 3 is fixedly connected to a rotating shaft 6. The rotating shaft 6 is rotatably inserted into the sliding support frame 2. The first slider 5 moves along the first T-shaped groove 4, thereby driving the sliding support frame 2, which is fixedly connected to the first slider 5, to move. The sliding support frame 2 drives the rotating support frame 3 to move backward, avoiding the rotating support frame 3 used for fixing being too close to the pole-mounted circuit breaker body 1. The rotating shaft 6 drives the rotating support frame 3 to rotate. One end of the rotating support frame 3 is connected to the utility pole. The semi-circular structure with a matching outer diameter can be fixed with bolts and nuts through another semi-circular installation structure. A slot 7 is opened in the first T-shaped slide 4. The front side of the first slider 5 is fixedly connected with a buckle 8 that matches the slot 7. The sliding support frame 2 is fixed by the buckle 8 engaging with the slot 7, which prevents the sliding support frame 2 from moving repeatedly with the first T-shaped slide 4 during movement. The rotating shaft 6 is tightly engaged, making rotation difficult, which prevents the rotating support frame 3 from rotating at any time during movement. The first anchoring hole 9 is opened on the sliding support frame 2, and the second anchoring hole 10 is opened on the rotating support frame 3. When the sliding support frame 2 moves backward to a suitable position, the anchor is driven through the first anchoring hole 9 and nailed into the pad of the pole-mounted circuit breaker body 1 to fix its position. The rotating support frame 3 is fixed by driving the anchor through the second anchoring hole 10 into the sliding support frame 2.

[0027] Please see Figures 5-7In this embodiment, a first protective cover 11 is installed on the top of the pole-mounted circuit breaker body 1. A first mounting base 12 is fixedly connected to both sides of the first protective cover 11. A second protective cover 13 is slidably connected to the top of the first protective cover 11. Anchors are passed through the first mounting base 12 to fix the first protective cover 11 to the top of the pole-mounted circuit breaker body 1. The first protective cover 11 provides protection for the circuit breaker body, while the second protective cover 13 protects the higher side of the outer casing of the pole-mounted circuit breaker. Two opposing second T-shaped grooves 14 are formed at the top of the first protective cover 11. A second slider 15 is slidably connected within the second T-shaped grooves 14. The second slider 15 is fixedly connected to the bottom of the second protective cover 13. The second slider 15 slides within the second T-shaped grooves 14, thereby moving the second protective cover 13 at the top of the first protective cover 11. This design does not... The second protective cover 13 can not only prevent the connection line from being obstructed, but also move above the connection line after the connection is completed to protect the connection point. The second protective cover 13 is fixedly connected to the front of the second mounting base 16. The bottom end of the second mounting base 16 is close to the top end of the first protective cover 11. By passing the anchor through the second mounting base 16, the second protective cover 13, which is fixedly connected to the second mounting base 16, can be fixed to the top end of the first protective cover 11 to prevent it from continuing to slide due to the second slider 15. The first protective cover 11 has a connection hole 17 that penetrates the outer wall of the first protective cover 11 on the rear side. The third protective cover 18 is fixedly connected to the rear side of the first protective cover 11 and is sleeved on the outside of the first connection hole 17. The connection line can pass through the connection hole and be installed at the connection point on the rear side. The third protective cover 18 can protect the connection area of ​​the connection line on the rear side.

[0028] During installation, the workers first pass the anchor through the first mounting base 12 and fix the first protective cover 11 to the top of the pole-mounted circuit breaker. Then, they push the sliding support frame 2 backward, and the buckle 8 comes out of the slot 7. The first slider 5 moves along the first T-shaped slide groove 4. Then, the anchor is aligned with the first anchor hole 9 and nailed in to fix the sliding support frame 2. Then, the rotating support frame 3 is rotated forcefully, and rotated inside the pole-mounted circuit breaker through the rotating shaft 6. This causes the rotating support frame 3 to change its angle and fit tightly against the outside of the utility pole. Then, another ring-shaped fixing frame is taken out and fitted tightly against the outside of the utility pole. Then, the bolt is passed through the rotating support frame 3 and the ring-shaped fixing frame, and then the nut is tightened to form a fixation.

[0029] Then connect the line to the pole-mounted circuit breaker, and push the second protective cover 13. The second slider 15 slides along the second T-shaped slide groove 14 to the front. Then the anchor passes through the second mounting base 16 and fixes the second protective cover 13 to the top of the first protective cover 11 to protect the front housing and the line connection. The line on the rear side passes through the connection hole and is fixed to the connection on the rear side. The third protective cover 18 can protect a section of the line on the rear side.

[0030] By adding a sliding mounting bracket and a rotating mounting bracket to the bottom of the pole-mounted circuit breaker through the above steps, the mounting bracket and the circuit breaker are integrated. Only the pole-mounted circuit breaker body 1 needs to be carried to move the integrated mounting bracket together. When the mounting bracket is installed on the utility pole, there is no need to worry about the pole-mounted circuit breaker falling due to excessive movement by the workers, which reduces the difficulty of installation. This solves the problem that existing pole-mounted circuit breakers need to be installed on utility poles with an additional support bracket, and the pole-mounted circuit breaker carried when installing the support bracket can easily restrict the movement of workers.
