Description

Technical Field

[0001] The present invention belongs to the technical field of circuit breakers, and in particular relates to a pole-mounted circuit breaker based on multi-environmental adaptation. Background Art

[0002] A circuit breaker is a protective and control device used in power systems. It rapidly interrupts current under harsh electrical fault conditions, such as short circuits or overloads, to protect electrical equipment and ensure safe system operation. Circuit breakers are typically designed with high-strength insulation and excellent interrupting capacity to handle high currents and high voltages. They are widely used in power plants, substations, and industrial power systems. Pole-mounted circuit breakers are switchgear mounted on power cable poles and are primarily used in power distribution networks to protect and control high- and medium-voltage circuits.

[0003] Chinese patent application number 202210428727.4 discloses a deep-fusion pole-mounted circuit breaker, comprising a circuit breaker body and a bracket for connecting the circuit breaker body to a utility pole. The bracket comprises a side plate fixedly connected to the utility pole and a top plate fixedly disposed on one side of the side plate. At least one mounting rod is fixedly disposed at the bottom of the circuit breaker body, and the top plate is provided with mounting slots equal in number to the number of mounting rods. The mounting slots are closed at one end in the horizontal direction and have openings at the other end for adjacent mounting rods to move in or out. When a mounting rod moves into the mounting slot, it can only move horizontally, not vertically. The top plate is provided with a locking member for preventing the mounting rod from moving out of the mounting slot. The locking member comprises a locking rod that slides vertically through the bottom wall of the mounting slot and a reset member for driving the locking rod into the mounting slot. The reset member can produce elastic deformation in the vertical direction. This patent has the effect of facilitating the installation of the circuit breaker body on the bracket.

[0004] When installing a pole-mounted circuit breaker, the conventional method is to lift the circuit breaker to a specified height. This process is cumbersome and unstable, and can easily cause the circuit breaker to collide with other locations and cause damage. In addition, the installation is inconvenient and the circuit breaker needs to be fixed at a high altitude. At the same time, different types and thicknesses of electric poles have different installation environments, and special fixing brackets are required for fixing. This makes installation and fixing inconvenient and not conducive to adjustment. Summary of the Invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention cooperates with the fixing mechanism and the telescopic rod, so that the installation box can first be fixed to the electric pole by the clamp, and then the installation box can be raised in a coordinated manner, so that the installation box can be more stable when the electric pole is raised, which not only avoids the problems of impact instability caused by direct lifting, but also saves physical strength, and can facilitate workers to install with less effort; specifically, when the two clamps are fixed on the electric pole, the lower clamp can be loosened first, and at this time, the installation box can still be fixed under the action of the upper clamp and the fixing mechanism; then push the telescopic rod upward, and at this time the limit spring is first compressed and then reset; when the lower support block slides to the top of the slot, the reset spring is also compressed, but before the limit Under the control of the spring rebound force and the angle of the telescopic rod, the lower support block will be limited to the top of the slot and will not move.

When the utility pole becomes thinner, the first tightening spring and the second tightening spring will reset, so that the first arc block and the second arc block can adaptably shrink and fit tightly against the utility pole. This can not only improve the installation adaptability and be suitable for a variety of utility poles, but also facilitate workers to quickly lock and loosen operations, making it convenient for workers to quickly adjust the height of the installation box.

[0040] Example

[0041] like Figures 1 to 8 As shown, a pole-mounted circuit breaker based on multi-environmental adaptation includes an installation box 100, a plurality of vacuum interrupter chambers 200 are installed on the top of the installation box 100, a pull rod 350 is fixedly connected to the bottom moving contact end of the vacuum interrupter chamber 200, and the pull rod 350 extends into the interior of the installation box 100; a drive shaft 310 is rotatably connected to the installation box 100, and a plurality of connecting rods 330 are fixedly connected to the drive shaft 310; the end of the connecting rod 330 away from the drive shaft 310 is rotatably connected to a bent rod 340; the lower end of the pull rod 350 is fixedly provided with a hinge groove 351, and the end of the bent rod 340 away from the connecting rod 330 is hinged to the corresponding hinge groove 351; the plurality of bent rods 330 are rotatably connected to the drive shaft 310; The middle part of 40 is commonly fixedly connected with a rotating shaft 320, and the rotating shaft 320 is rotatably connected to the inside of the installation box 100; the bottom of the installation box 100 is provided with a fixing mechanism 400, and the fixing mechanism 400 includes two bottom plates 410 fixed to the bottom of the installation box 100, and one end of the bottom plate 410 is fixedly connected with a second hinge groove 420, and the second hinge groove 420 is hinged to one end of the telescopic rod 500; the end of the telescopic rod 500 away from the second hinge groove 420 is commonly fixedly connected with a clamp 600, and the end of the bottom plate 410 away from the second hinge groove 420 is commonly fixedly connected with another clamp 600, and the two clamps 600 are installed on the utility pole.

[0042] The present invention cooperates with the fixing mechanism 400 and the telescopic rod 500, so that the installation box 100 can first be fixed to the utility pole through the clamp 600, and then the installation box 100 can be raised in a coordinated manner, so that the installation box 100 can be more stable when the utility pole is raised, which not only avoids the problems of impact and instability caused by direct lifting, but also saves physical strength, and can facilitate workers to install with less effort; a detailed description will be given later.

[0043] It is worth noting that the driving shaft 310 controls the curved rod 340 and the connecting rod 330 to make the pull rod 350 rise and fall, thereby closing the circuit breaker. At the same time, the driving shaft 310 can be controlled by the operating handle and the energy storage mechanism. This is the existing technology and will not be described in detail here.

[0044] Furthermore, the telescopic rod 500 includes a telescopic rod body 530, one end of which is fixedly provided with a first hinge end 531, which is hingedly connected to the corresponding second hinge groove 420; a limit block 532 is fixedly provided at the end of the telescopic rod body 530 away from the first hinge end 531, and a telescopic tube 540 is sleeved on the telescopic rod body 530, and the limit block 532 is slidably connected to the inner wall of the telescopic tube body 540; a limit ring 541 is extended inwardly from the end of the telescopic tube body 540 close to the telescopic rod body 530, and the inner side of the limit ring 541 is slidably connected to the outer wall of the telescopic rod body 530;

[0045] The telescopic tube 540 is closed at one end away from the telescopic rod 530, and a limit spring 550 is provided inside the telescopic tube 540. The compressive elastic force of the limit spring 550 not only serves to limit the position but also supports the telescopic rod 500, which will be described in detail later.

[0046] Furthermore, the end of the bottom plate 410 away from the second hinge groove 420 is fixedly connected to a limit plate 460. The limit plate 460 has a notch 461 extending vertically therethrough. A lower support block 830 is provided on one side of the notch 461. The lower support block 830 is fixedly connected to the second hinge end 831. The end of the telescopic tube 540 away from the telescopic rod 530 is fixedly provided with a third hinge groove 542. The second hinge end 831 passes through the notch 461 and is hingedly connected to the third hinge groove 542.

[0047] The two lower support blocks 830 are fixedly connected to a lower connecting member 840 on one side away from the second hinge end 831. A clamping hoop 600 is mounted on the lower connecting member 840. The upper end of the limiting plate 460 is fixedly connected to an upper support block 810. Both upper support blocks 810 are fixedly connected to an upper connecting member 820, which is mounted on another clamping hoop 600. This design allows the upper clamping hoop 600 to follow the movement of the limiting plate 460, while the lower clamping hoop 600 follows the movement of the lower support block 830.

[0048] Furthermore, a through hole is opened through the lower support block 830, and the bottom of the upper support block 810 is fixedly connected with a slide rod 850, and the slide rod 850 passes through the through hole on the corresponding lower support block 830 and the end of the slide rod 850 is fixedly provided with a limiting protrusion 851; a return spring 860 is sleeved on the slide rod 850, and the two ends of the return spring 860 are fixedly connected to the upper support block 810 and the lower support block 830 respectively.

[0049] When the two clamps 600 are fixed on the utility pole, the lower clamp 600 can be loosened first. At this time, the installation box 100 can still be fixed under the action of the upper clamp 600 and the fixing mechanism 400; then the telescopic rod 500 is pushed upward, and the limit spring 550 is first compressed and then reset; when the lower support block 830 slides above the notch 461, the reset spring 860 is also compressed, but under the control of the rebound force of the limit spring 550 and the angle of the telescopic rod 500, the lower support block 830 will be limited to above the notch 461 and will not move. At this time, the worker can quickly lock the lower clamp 600 No additional manual fixation is required; after fixing the lower clamp 600, continue to loosen the upper clamp 600 and push the bottom plate 410 upward; at this time, the telescopic rod 500 will rotate in the opposite direction, and the reset spring 860 will reset at the same time. In this process, the staff can quickly and effortlessly raise the installation box 100; when it rises to the point where the lower support block 830 is located below the slot 461, lock the upper clamp 600, and then continuously repeat the above process, and finally make the installation box 100 reach the specified height, so that the installation box 100 can be more stable and safe when rising on the utility pole, and it can also be convenient for workers to install with less effort.

[0050] It is worth noting that this installation method is only applicable to the first installation of utility poles or when there are no other redundant fixings on the utility poles. In this case, it avoids problems such as collision and instability caused by lifting, and also makes it convenient for workers to install with less effort.

[0051] Furthermore, the lower connecting member 840 and the upper connecting member 820 have the same structure; one side of the lower connecting member 840 is fixedly connected to the lower support block 830, and the other side of the lower connecting member 840 is provided with a horizontal sliding groove 841, and a second sliding rod 842 is fixedly connected to the horizontal sliding groove 841, and two sliders 630 are slidingly connected to the second sliding rod 842; a first tightening spring 843 is provided between each slider 630 and one end of the horizontal sliding groove 841, and the first tightening spring 843 is sleeved on the second sliding rod 842; the two ends of the first tightening spring 843 are respectively fixedly connected to the corresponding slider 630 and the horizontal sliding groove 841; the two sliders 630 are jointly fixedly connected to the clamp 600.

[0052] Furthermore, the clamp 600 includes two first arc blocks 610 and two second arc blocks 660; both ends of each first arc block 610 are fixed with a first receiving block 620, and both ends of each second arc block 660 are fixed with a second receiving block 670;

[0053] Each slider 630 is detachably fixedly connected to a first receiving block 620, and the other two first receiving blocks 620 are fixedly connected to a third slide rod 640; each third slide rod 640 is slidably connected to a second receiving block 670; the end of the third slide rod 640 away from the first receiving block 620 is fixedly provided with a second limiting protrusion 641, and the third slide rod 640 is provided with a second tightening spring 650, and the two ends of the second tightening spring 650 are respectively fixedly connected to the second receiving block 670 and the second limiting protrusion 641; the two first arc blocks 610 and the two second arc blocks 660 together form a circular-like structure.

[0054] Through the cooperation of the first tightening spring 843 and the second tightening spring 650, the two first arc blocks 610 and the two second arc blocks 660 can adaptively expand or contract, which facilitates the rapid adjustment of the clamp 600, which will be described in detail later.

[0055] Furthermore, wire rope mounting holes 680 are formed through the interiors of the two first arc blocks 610; wire rope mounting holes 680 are also formed through the interiors of the two second arc blocks 660, and through the interiors of the second receiving blocks 670 of the second arc blocks 660 and away from the first arc blocks 610; a wire rope 690 is passed through all the wire rope mounting holes 680, and both ends of the wire rope 690 respectively pass through the wire rope mounting holes 680 on the second receiving blocks 670 of the second arc blocks 660 and away from the first arc blocks 610;

[0056] A threaded hole 681 is provided on the second receiving block 670 of the second arc block 660 and away from the first arc block 610 . The threaded hole 681 is connected to the corresponding wire rope mounting hole 680 . A locking screw 682 is screwed on the threaded hole 681 for locking the wire rope 690 .

[0057] The present invention adopts the structural design of the clamp 600, so that the clamp 600 can adapt to different thicknesses of electric poles, and can also adapt to electric poles of constantly changing thicknesses; when the first arc block 610 and the second arc block 660 are both mounted on the electric pole, if the electric pole is thicker, then the first tightening spring 843 and the second tightening spring 650 will be acted on to compress the first tightening spring 843 and the second tightening spring 650. At this time, the first arc block 610 and the second arc block 660 will expand adaptively and cling to the electric pole; when it is necessary to fix the clamp 600, it is only necessary to tighten the locking screw 682 to make the wire rope 690 tightly clamp the first arc block 610 and the second arc block 660. Yes, if necessary, the first receiving block 620 and the second receiving block 670 can be reinforced by other steel wires; when the clamp 600 needs to be loosened, the locking screw 682 can be loosened; and when the height of the installation box 100 needs to be adjusted, the clamp 600 can automatically adjust its adaptability according to the thickness of the utility pole. When the utility pole becomes thinner, the first tightening spring 843 and the second tightening spring 650 will reset, so that the first arc block 610 and the second arc block 660 will shrink adaptably and fit tightly against the utility pole. This can not only improve the installation adaptability and be suitable for a variety of utility poles, but also facilitate workers to quickly lock and loosen operations, and facilitate workers to quickly adjust the height of the installation box 100.

[0058] It is worth noting that when the first arc block 610 and the second arc block 660 are adaptively contracted, the wire rope 690 may be bent to a certain extent. At this time, it is only necessary to straighten the two ends of the wire rope 690; and the structure in the drawings of the present invention does not limit the specific size, and can be adaptively adjusted according to the specific size of the pole.
