Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and particularly to a safe type pole-mounted circuit breaker with multiple protections. Background Art

[0002] A pole-mounted circuit breaker is a high-voltage power distribution device installed on an electric pole, mainly used for automatically cutting off faults such as overload and short circuit in a power system to protect lines and equipment from damage. It can quickly break the fault current, prevent the spread of faults, and support manual or remote control operations. Its core structure includes a contact system (moving contact and static contact), an operating mechanism, an arc extinguishing device, and a housing. When working, an electromagnetic trigger activates a mechanical switch to cut off the circuit after detecting a fault current, and at the same time, the arc extinguishing device quickly extinguishes the arc.

[0003] Existing pole-mounted circuit breakers are usually installed naked at a high position on an outdoor electric pole. Therefore, they are not only vulnerable to the invasion of external dust, rain, and pollutants, resulting in a short service life of the pole-mounted circuit breaker, but also prone to violent vibration due to wind impact in windy weather and loosening of some structures of the circuit breaker, resulting in poor overall installation stability of the pole-mounted circuit breaker.

[0004] Based on the above situation, the present invention proposes a safe type pole-mounted circuit breaker with high stability and multiple protections. Summary of the Invention

[0005] In order to overcome the shortcomings that existing pole-mounted circuit breakers are installed naked at a high position on an outdoor electric pole, not only vulnerable to the invasion of external dust, rain, and pollutants, resulting in a short service life of the pole-mounted circuit breaker, but also prone to violent vibration due to wind impact in windy weather and loosening of some structures of the circuit breaker, resulting in poor overall installation stability of the pole-mounted circuit breaker, the present invention provides a safe type pole-mounted circuit breaker with high stability and multiple protections.

[0006] A safe type pole-mounted circuit breaker with multiple protections includes a box body, pole columns, a mounting plate frame, screws, an isolation housing, air collecting plates, air guide pipes, and flow dividing plates. The box body is fixedly connected with axially distributed pole columns. The box body is movably connected with a pair of screws.

A connecting block is fixedly connected between the pole column and the isolation housing. A stabilizing rope is fixedly connected between the connecting block and the clamping block, and the stabilizing rope is equipped with a first adjuster.

[0011] Optionally, it further includes a heat dissipation mechanism. The heat dissipation mechanism is arranged on the isolation housing and includes an opening and closing plate, a guide frame, a liquid storage tank, a diversion pipe, and an extrusion cylinder. The guide frames distributed axially are fixedly connected to the isolation housing. The guide frames are slidably connected with the opening and closing plate.

The isolation housing is fixedly connected with a pair of liquid storage tanks, and a diversion pipe is fixedly connected and communicated between the liquid storage tank and the pair of extrusion cylinders.

[0012] Optionally, it further includes a clamping mechanism. The clamping mechanism is arranged on the box body and includes a pressing plate, an elastic clamping frame, and a spring piece. The paired pressing plates are slidably connected to the box body. A pair of spring pieces are fixedly connected between the pressing plate and the box body. The pressing plate is in extrusion cooperation with the screw. An elastic clamping frame is fixedly connected between the paired pressing plates, and the elastic clamping frame is in extrusion cooperation with the mounting plate frame.

[0013] Optionally, the lower part of the elastic clamping frame is provided with an inclined surface and is hook-shaped.

[0014] Optionally, it further includes a reinforcement mechanism. The reinforcement mechanism is arranged on the pressing plate and includes a pressing rope and a second adjuster.

[0015] The beneficial effects of the present invention are as follows: 1. Through components such as the air collecting plate and the flow splitter, the present invention can not only provide wrapped protection for components such as the pole column, thereby reducing the erosion of external dust, rainwater, and pollutants on components such as the pole column, so as to improve the overall service life of the pole-mounted circuit breaker, but also guide the air blown to both sides of the isolation housing, thereby reducing the impact of the airflow on components such as the isolation housing and improving the overall installation stability of this pole-mounted circuit breaker.

[0016] 2. Through components such as the stabilizing rope and the connecting block, the present invention can not only reinforce components such as the pole column and the isolation housing in the front-back direction, thereby preventing components such as the pole column and the isolation housing from vibrating violently and loosening due to wind impact, but also enhance the connection stability between the box body and the mounting plate frame, and improve the overall installation stability of this pole-mounted circuit breaker.

[0017] 3. Through components such as the opening and closing plate and the liquid storage tank, the present invention can not only close the ventilation opening when the temperature inside the isolation housing is relatively low, thereby reducing the erosion of components such as the terminal post by external dust, rainwater, and pollutants, but also open the ventilation opening and conduct ventilation and heat dissipation when the temperature inside the isolation housing is relatively high, improving the heat dissipation effect and practicality of this pole-mounted circuit breaker.

[0018] 4. Through components such as the pressing plate and the elastic clamping frame, the present invention can hook the mounting plate frame with the elastic clamping frame when installing components such as the box body, thereby enhancing the connection stability between the box body and the mounting plate frame to prevent components such as the box body from falling off the mounting plate frame due to excessive wind impact, improving the overall installation stability and safety of this pole-mounted circuit breaker.

[0019] 5. Through components such as the pressing rope and the second adjuster, the present invention can reinforce components such as the terminal post and the isolation housing in the left-right direction, thereby preventing components such as the terminal post and the isolation housing from vibrating violently and becoming loose due to wind impact, improving the overall installation stability of this pole-mounted circuit breaker.

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0034] Embodiment 1

[0035] A safe type pole-mounted circuit breaker with multiple protection and reinforcement, as Figures 1 - 4 shown, includes a box body 1, a terminal post 101, a mounting plate frame 11, a screw 12, an isolation housing 13, an air collecting plate 14, an air duct 15, and a flow dividing plate 16. The terminal post 101 distributed axially is fixedly connected to the top of the box body 1. Screws 12 distributed symmetrically front and back are movably connected to both the left and right sides of the box body 1. The mounting plate frame 11 is fixedly connected to the bottom of the box body 1 through the screw 12, and the mounting plate frame 11 is threadedly connected to the screw 12. The isolation housing 13 is fixedly connected to the top of the box body 1. Air collecting plates 14 are fixedly connected to both the front and back sides of the isolation housing 13. Longitudinally distributed air ducts 15 are fixedly connected and communicated to both the left and right sides between the air collecting plate 14 and the isolation housing 13. Longitudinally distributed flow dividing plates 16 are fixedly connected to both the left and right parts of the isolation housing 13.

[0036] As Figure 3 and Figure 4 shown, a ventilation opening distributed axially is provided at the top of the isolation housing 13.

[0037] As Figure 3 and Figure 4 shown, the inside of the air collecting plate 14 is hollow and provided with an obliquely arranged air inlet distributed longitudinally.

[0038] As Figure 4 shown, the shunt plate 16 is obliquely arranged, and the orientations of the shunt plates 16 on the upper and lower sides are opposite.

[0039] When workers need to install the circuit breaker on a utility pole, they can first place components such as the box body 1 on the mounting plate frame 11 and turn the screw 12 clockwise, so that the screw 12 rotates and moves downward until it is screwed into the mounting plate frame 11, thereby fixing components such as the box body 1 on the mounting plate frame 11. Then, the components such as the box body 1 can be fixed at a high position on the utility pole through the mounting plate frame 11. At this time, components such as the isolation housing 13 can provide wrap-around protection for components such as the pole column 101, thereby reducing the erosion of components such as the pole column 101 by external dust, rain, and pollutants, and improving the overall service life of the pole-mounted circuit breaker. When the front and rear sides of the isolation housing 13 are impacted by air flow, the air flow will first enter the air collecting plate 14 through the obliquely arranged air inlets distributed longitudinally, and then, under the guidance of the hollow air collecting plate 14, it will move left or right and blow towards the shunt plate 16 through the air duct 15, thereby guiding the air blowing towards the front and rear sides of the isolation housing 13, reducing the impact of the air flow on components such as the isolation housing 13, and improving the stability of components such as the isolation housing 13. And at this time, the air flows blown out by the air ducts 15 on the left and right sides will first cause a wind impact on the isolation housing 13, and then, under the action of the obliquely arranged shunt plate 16, they will be discharged upward or downward respectively. Since the total amount of air flow guided to the air ducts 15 on the left and right sides by the air collecting plate 14 is basically the same, the wind impacts caused by the air flows blown out by the air ducts 15 on the left and right sides on the isolation housing 13 are basically the same in magnitude and opposite in direction, so the air flows on the left and right sides will not only not affect the stability of components such as the isolation housing 13 in the left-right direction, but also improve the stability of components such as the isolation housing 13 in the front-rear direction to a certain extent, thereby improving the overall stability of components such as the isolation housing 13.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figure 5 and Figure 6 shown, it further includes a stabilizing mechanism. The stabilizing mechanism is arranged on the box body 1. The stabilizing mechanism includes a clamping block 2, a stabilizing rope 21, a first adjuster 22, and a connecting block 23. The axially distributed clamping blocks 2 are respectively rotatably connected to the front and rear sides of the bottom of the box body 1. The clamping block 2 is in contact and cooperation with the mounting plate frame 11. A connecting block 23 is fixedly connected between the pole column 101 and the isolation housing 13. A stabilizing rope 21 is fixedly connected between the connecting block 23 and the clamping block 2. A first adjuster 22 is installed in the middle of the stabilizing rope 21.

[0042] When installing components such as the box body 1 on the mounting plate frame 11, the worker can also turn the first adjuster 22 as needed to adjust the tension of the stabilizing rope 21. After the adjustment is completed, the clamping block 2 can be rotated downward to hook the bottom of the mounting plate frame 11, and the stabilizing rope 21 will be further tightened immediately. In this way, not only can components such as the pole 101 and the isolation housing 13 be strengthened in the front-back direction by means of the stabilizing rope 21 and the clamping block 2, so as to prevent components such as the pole 101 and the isolation housing 13 from vibrating violently and becoming loose due to wind impact, but also the installation stability between the box body 1 and the mounting plate frame 11 can be enhanced.

[0043] As Figure 7 and Figure 8 shown, it further includes a heat dissipation mechanism. The heat dissipation mechanism is arranged on the isolation housing 13. The heat dissipation mechanism includes an opening and closing plate 3, a guide frame 31, a liquid storage tank 32, a diversion pipe 33 and an extrusion cylinder 34. The axially distributed guide frames 31 are fixedly connected to the upper part of the isolation housing 13. The bottom of the guide frame 31 is slidably connected with the opening and closing plate 3. Four extrusion cylinders 34 are fixedly connected to the left and right sides of the isolation housing 13, and the piston rods of the extrusion cylinders 34 are fixedly connected to the adjacent opening and closing plates 3. Liquid storage tanks 32 are fixedly connected to the left and right sides inside the isolation housing 13, and diversion pipes 33 are fixedly connected and communicated between the liquid storage tanks 32 and the adjacent two extrusion cylinders 34.

[0044] When the internal temperature of the isolation housing 13 gradually rises due to the heat generated by the work of components such as the pole 101, the low-boiling-point and volatile liquid stored in the liquid storage tank 32 will continuously volatilize and turn into gas, and the gas generated by the liquid volatilization will enter the extrusion cylinder 34 through the diversion pipe 33. The air pressure in the extrusion cylinder 34 will immediately increase. At this time, the gas in the extrusion cylinder 34 will squeeze the piston rod and make it move away from the cylinder body. The opening and closing plate 3 will immediately move together with the piston rod of the extrusion cylinder 34 and no longer block the ventilation opening at the top of the isolation housing 13. At this time, components such as the pole 101 can dissipate heat through the ventilation opening, so as to prevent components such as the pole 101 from being damaged due to overheating. When the internal temperature of the isolation housing 13 gradually decreases due to ventilation and heat dissipation, the gas generated by the liquid volatilization will gradually liquefy, the air pressure in the extrusion cylinder 34 will immediately decrease, and the piston rod of the extrusion cylinder 34 will also move reversely and reset under the action of the external atmospheric pressure. The opening and closing plate 3 will also move reversely and reset together with the piston rod of the extrusion cylinder 34 and re-block the ventilation opening at the top of the isolation housing 13 to reduce the erosion of components such as the pole 101 by external dust, rainwater and pollutants.

[0045] As Figure 9 and Figure 10As shown, it further includes a clamping mechanism. The clamping mechanism is arranged on the box body 1 and includes a pressing plate 4, an elastic clamping frame 41 and an elastic sheet 42. The two pressing plates 4 are respectively slidably connected to the left and right sides of the lower part of the box body 1. There are two front and rear elastic sheets 42 fixedly connected between the pressing plate 4 and the box body 1. The pressing plate 4 is in extrusion fit with the screw 12. An elastic clamping frame 41 is fixedly connected between the left and right pressing plates 4, and the elastic clamping frame 41 is in extrusion fit with the mounting plate frame 11.

[0046] As Figure 9 and Figure 10 shown, the lower part of the elastic clamping frame 41 is provided with an inclined surface and is hook-shaped.

[0047] When the worker turns the screw 12 forward and makes the screw 12 rotate and move downward at the same time, the screw 12 will contact and press the pressing plate 4, so that the pressing plate 4 drives the elastic clamping frame 41 to move downward, and the elastic sheet 42 is immediately compressed. When the elastic clamping frame 41 with an inclined surface at the lower part moves downward, it will contact the mounting plate frame 11 and be pressed to deform inward. When the elastic clamping frame 41 continues to move downward until the inclined surface separates from the mounting plate frame 11, the hook-shaped elastic clamping frame 41 at the lower part will deform outward and return to its original shape under its own elasticity and hook the bottom of the mounting plate frame 11. In this way, the installation stability between the box body 1 and the mounting plate frame 11 can be enhanced, so as to prevent components such as the box body 1 from falling off the mounting plate frame 11 due to excessive wind impact.

[0048] As Figure 11 and Figure 12 shown, it further includes a reinforcement mechanism. The reinforcement mechanism is arranged on the pressing plate 4 and includes a pressing rope 5 and a second adjuster 51. The front and rear pressing ropes 5 are both fixedly connected between the left and right pressing plates 4. The pressing rope 5 is slidably connected to the isolation housing 13, and the second adjusters 51 are installed on both the left and right parts of the pressing rope 5.

[0049] Before installing components such as the box body 1 on the mounting plate frame 11, the worker can also turn the second adjuster 51 as needed to adjust the tension of the pressing rope 5. When the worker turns the screw 12 forward and makes the screw 12 rotate and move downward at the same time, the pressing plate 4 will also move downward under the extrusion of the screw 12, and the front and rear pressing ropes 5 will be further tightened immediately, and components such as the pole 101 and the isolation housing 13 will be reinforced in the left and right directions, so as to prevent components such as the pole 101 and the isolation housing 13 from vibrating violently and becoming loose due to wind impact.

[0050] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
