Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pole-mounted circuit breakers, in particular to a dustproof shell for primary and secondary fusion pole-mounted circuit breakers. BACKGROUND

[0002] The primary and secondary fusion pole-mounted circuit breaker, as a crucial device in the power system, is specially designed and installed on the electric pole to facilitate on-site operation and maintenance of power workers. This circuit breaker integrates advanced automatic control technology, and its main function is to accurately and quickly automatically remove single-phase ground faults in the power grid, and also automatically isolate the fault area when inter-phase short-circuit faults occur, thereby effectively protecting the power supply safety and stability of non-fault users in the power grid and avoiding larger-scale power outages caused by local faults. It has a very wide and important application in various existing power grid structures.

[0003] However, under the existing technical conditions, there are some urgent improvements for the dustproof shell designed to protect the pole-mounted circuit breaker. Generally, the angle of the heat dissipation opening provided on such a dustproof shell is fixed, and the downward inclined design is commonly used. From the perspective of heat dissipation function, this heat dissipation opening design can indeed achieve heat dissipation of the pole-mounted circuit breaker inside the dustproof shell to a certain extent, maintaining the normal operating temperature of the equipment. However, the problem is that due to the inclined setting of the heat dissipation opening angle, when external air tries to enter the dustproof shell through the heat dissipation opening to assist in heat dissipation, the flow path of the air will change. The air will inevitably come into contact with the wall of the heat dissipation opening at the moment of flowing into the heat dissipation opening, and then enter the dustproof shell inside the channel in a tortuous way. This non-linear air flow mode greatly weakens the direct heat dissipation effect of the air on the pole-mounted circuit breaker, because the air cannot directly and quickly blow to the heating parts of the pole-mounted circuit breaker, resulting in that the heat cannot be timely and effectively taken out.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0042] As shown in the drawings, Figures 1-9 The present application provides a dustproof shell for a primary and secondary fused pole-mounted circuit breaker, which comprises a dustproof box 10, a circuit breaker body 11 installed inside the dustproof box 10, and further comprises a heat dissipation assembly 20 and an adjusting assembly 30 installed on the top of the dustproof box 10.

[0043] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the adjusting assembly 30 comprises a fixed plate 31 fixedly connected to the dustproof box 10, one side of the fixed plate 31 is provided with a servo motor 32, the output shaft of the servo motor 32 penetrates the fixed plate 31 and is connected with a rotating shaft 33, the fixed plate 31 is rotatably connected with a rotating shaft 34, the rotating shaft 33 and the rotating shaft 34 are both connected with a meshing connecting gear 35, the dustproof box 10 is connected with a plurality of connecting plates 37 on both sides, the connecting plates 37 are rotatably connected with heat dissipation plates 372 through positioning rods 371, one side of the heat dissipation plates 372 is connected with rubber folding pieces 373, the rubber folding pieces 373 are fixedly connected to one side of the dustproof box 10, the heat dissipation plates 372 are both fixedly connected with connecting ropes 36 between the rotating shaft 33 and the rotating shaft 34, the heat dissipation plates 372 are slidably connected with filter screens 38 in the inner wall through a cleaning assembly 40, the adjusting assembly 30 further comprises arc-shaped blocks 361 fixedly connected to the dustproof box 10 and in contact with the connecting ropes 36, and the heat dissipation plates 372 are connected with mounting ropes 39 between each other;

[0044] In order to guide the air to directly flow to the circuit breaker body 11 to improve the heat dissipation effect, the servo motor 32 can be started, the servo motor 32 is driven to rotate the rotating shaft 33, the rotating shaft 34 is rotated in the opposite direction of the rotating shaft 33 through the transmission action of the connecting gear 35, in the rotating process of the rotating shaft 33 and the rotating shaft 34, the connecting rope 36 is pulled, and then the heat dissipation plates 372 are driven to rotate around the positioning rod 371, so that the two heat dissipation plates 372 gradually tend to be horizontal;

[0045] In the moving process of the heat dissipation plates 372, the rubber folding pieces 373 are squeezed, and the heat dissipation plates 372 are synchronously moved through the mounting ropes 39, when the heat dissipation plates 372 on both sides are in the horizontal state, the air can directly flow to the circuit breaker body 11, and the hot air is more smoothly discharged, in addition, the filter screen 38 filters the entering air, so that the dust and impurities are attached to the surface;

[0046] Adjusting the heat dissipation plates 372 to be horizontal can also increase the air inlet and outlet, effectively improve the heat dissipation efficiency, and reduce the internal temperature of the dustproof box 10, so as to ensure the stable operation of the circuit breaker body 11.

[0047] As shown in the accompanying drawings, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the cleaning assembly 40 includes two chutes 41 opened in the interior of the heat sink 372, the inner walls of each chute 41 are fixedly connected with a fixed rod 42, and the outer periphery of the fixed rod 42 is sleeved with an extension spring 421, the outer periphery of the two fixed rods 42 is slidably connected with an acceleration piece, the acceleration piece includes a sliding block 43 slidably connected with the outer periphery of the fixed rod 42 and a baffle 431 fixedly connected between the sliding block 43, the inner wall of the sliding block 43 is fixedly connected with a fixed column 432, and the fixed column 432 is rotatably connected with a counterweight 434 through a torsional spring 433 on the outer periphery, one side of the counterweight 434 is provided with an avoiding slot 435, and the interior of the heat sink 372 is fixedly connected with two contact blocks 44 in contact with the filter screen 38;

[0048] When the heat sink 372 is in a horizontal state, but the air flow rate outside is weak, causing the air flowing into the interior of the dustproof box 10 along the heat sink 372 to be too slow to effectively take out heat, the servo motor 32 can be started, the servo motor 32 is operated to drive the rotating shaft 33 to rotate, the rotating shaft 34 is driven to rotate in the direction opposite to the rotating shaft 33 through the transmission of the connecting gear 35, and the rotating shaft 34 is driven to rotate in the direction opposite to the rotating shaft 33 through the transmission of the connecting gear 35. With the rotation of the rotating shaft 33 and the rotating shaft 34, the connecting rope 36 is pulled, and the heat sink 372 is rotated with the positioning rod 371 as the center, so that the two heat sinks 372 are inclined upward;

[0049] Since the heat sink 372 is inclined upward, the hot air flowing out along the heat sink 372 can be utilized by the characteristic of hot air rising, so as to improve the exhaust efficiency of the hot air in the interior of the dustproof box 10, and the hot air flowing out continues to float upward and does not gather around the dustproof box 10, thereby avoiding the formation of a high-temperature area around the dustproof box 10;

[0050] In addition, when the heat sink 372 is inclined upward, the sliding block 43 and the baffle 431 slide downward on the outer periphery of the fixed rod 42, at this time the elastic force of the torsional spring 433 drives the counterweight 434 to rotate on the outer periphery of the fixed column 432, and the counterweight 434 is tightly attached to the sliding block 43 through the avoiding slot 435, at this time the vertical angle between the counterweight 434 and the baffle 431 is less than ninety degrees;

[0051] After a long time of use, dust is attached to the surface of the filter screen 38, affecting the air inlet efficiency, so the filter screen 38 needs to be cleaned. Similarly, the servo motor 32 is started to drive the rotating shaft 33 to rotate, the rotating shaft 34 is reversely rotated through the transmission of the connecting gear 35, and with the rotation of the rotating shaft 33 and the rotating shaft 34, the connecting rope 36 is elongated, the heat sink 372 pulls the connecting rope 36 under the action of its own weight, and rotates with the positioning rod 371 as the center, so that the two heat sinks 372 are inclined downward;

[0052] With the heat dissipation plate 372 inclined downward, the sliding block 43 and the baffle 431 slide along the fixed rod 42 under the action of their own weight. Since the direction of gravity changes, the elastic force of the torsional spring 433 is smaller than the weight of the counterweight 434. During the downward sliding process, the counterweight 434 rotates along the outer periphery of the fixed column 432 and presses the torsional spring 433. When the counterweight 434 rotates to contact the baffle 431, an impact is generated on the baffle 431, accelerating the sliding speed of the baffle 431 and the sliding block 43 along the outer periphery of the fixed rod 42. During the downward sliding process, the sliding block 43 and the baffle 431 contact the filter screen 38, driving the filter screen 38 to slide downward and press the extension spring 421. When the filter screen 38 contacts the contact block 44 during the downward sliding process, the dust adsorbed on the surface of the filter screen 38 is shaken off, reducing dust adhesion and improving the air intake efficiency.

[0053] As shown in Figure 1 、 Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 The contact block 44 is internally connected with a knocking assembly 50. The knocking assembly 50 includes an inner cavity 51 formed in the contact block 44 and a vibrating piece connected to the side of the dustproof box 10. The inner wall of the inner cavity 51 is slidably connected with a knocking column 511 in contact with the filter screen 38. One side of the knocking column 511 is connected with a sliding rod 512 extending out of the contact block 44. The outer periphery of the sliding rod 512 is sleeved with a pressure spring 513. The side of the heat dissipation plate 372 is formed with a moving groove 52. The outer periphery of the sliding rod 512 is fixedly connected with a moving rod 53 slidably connected with the moving groove 52. The moving rod 53 extends out of the moving groove 52. The vibrating piece includes a plurality of fan-shaped plates 54 fixedly connected to the side of the dustproof box 10. The center of the fan-shaped plate 54 is the same as the center of the heat dissipation plate 372. The side of the fan-shaped plate 54 is formed with a round corner 541. The side of the fan-shaped plate 54 is connected with a plurality of protrusions 542. The adjacent protrusions 542 are formed with a groove 543.

[0054] At the same time, as the heat dissipation plate 372 gradually inclines downward, the moving rod 53 will first contact the round corner 541 of the fan-shaped plate 54. The round corner 541 will push the moving rod 53 to slide in the moving groove 52, thereby pulling the sliding rod 512 to slide in the contact block 44. The movement of the sliding rod 512 will make the knocking column 511 retract into the contact block 44 and simultaneously press the pressure spring 513.

[0055] As the heat dissipation plate 372 continues to incline downward, when the filter screen 38 contacts the contact block 44, the moving rod 53 will gradually contact the protrusion 542, further pressing the pressure spring 513. When the moving rod 53 gradually moves away from the contact with the protrusion 542, the pressure spring 513 will rebound, pushing the knocking column 511 to slide in the inner cavity 51 and knocking the frame of the filter screen 38.

[0056] Moreover, the greater the downward inclination angle of the heat dissipation plates 372, the more times the knocking column 511 knocks the filter screen 38, so that the dust adhered to the surface of the filter screen 38 can be cleaned more effectively.

[0057] As shown in Figure 1 , Figure 2 , the heat dissipation assembly 20 comprises a mounting frame 21 fixedly connected to the top of the dustproof box 10, a suction fan 22 is mounted on the top of the mounting frame 21, one side of the suction fan 22 is connected with a suction pipe 23, and the suction pipe 23 extends into the dustproof box 10, one side of the suction fan 22 is connected with an air outlet 24.

[0058] When the temperature inside the dustproof box 10 is too high, the suction fan 22 can also be started to make the suction pipe 23 absorb the hot air inside the dustproof box 10, so that the hot air is discharged along the air outlet 24.

[0059] Working principle: in order to realize that the air directly flows to the circuit breaker body 11 to improve the heat dissipation effect, the servo motor 32 can be started, the servo motor 32 drives the rotating shaft 33 to rotate, and the rotating shaft 34 rotates in the opposite direction of the rotating shaft 33 through the transmission of the connecting gear 35, the connecting rope 36 is pulled when the rotating shaft 33 and the rotating shaft 34 rotate, and then the heat dissipation plates 372 are rotated with the positioning rod 371 as the center to make the two heat dissipation plates 372 tend to be horizontal, in this process, the rubber folding piece 373 is squeezed by the heat dissipation plates 372, and the multiple heat dissipation plates 372 are synchronously moved through the installation rope 39, when the two heat dissipation plates 372 are in the horizontal state, the air can directly flow to the circuit breaker body 11, and the hot air is discharged more smoothly, at the same time, the filter screen 38 filters the dust in the air, so that the dust adheres to the surface, the heat dissipation plates 372 are adjusted to the horizontal state, the air inlet and outlet are increased, the heat dissipation efficiency is improved, the internal temperature of the dustproof box 10 is reduced, and the stable operation of the circuit breaker body 11 is ensured.

[0060] If the heat dissipation plates 372 are in the horizontal state but the air flow outside is weak, the air flow into the dustproof box 10 is slow, and the heat dissipation effect is poor, the servo motor 32 can be started again to make the heat dissipation plates 372 incline upward through the same transmission mode above, the hot air will flow out along the upward inclined heat dissipation plates 372 by using the upward rising characteristics of the hot air, the hot air discharge efficiency inside the dustproof box 10 is improved, and after the hot air flows out, it continues to float upward to avoid forming a high-temperature area around the dustproof box 10.

[0061] After long time use, dust will be attached to the surface of the filter screen 38, and the servo motor 32 is started to drive the connecting rope 36 to be extended through the opposite way of transmission, and the heat sink 372 pulls the connecting rope 36 and rotates around the positioning rod 371 under its own weight, and the two heat sinks 372 are inclined downward, at this time, the sliding block 43 and the baffle 431 slide along the fixed rod 42 under its own weight, because the direction of gravity changes, the torsional spring 433 has a smaller elastic force than the weight of the counterweight block 434, the counterweight block 434 rotates along the outer periphery of the fixed column 432 and presses the torsional spring 433 during the sliding process, when the counterweight block 434 rotates to contact the baffle 431, it will impact the baffle 431, and accelerate the sliding of the sliding block 43 and the baffle 431 along the outer periphery of the fixed rod 42, and during the descending process, the two contact the filter screen 38 to drive it to slide downward together and press the extension spring 421, and the filter screen 38 slides downward and impacts the contact block 44 to shake off the dust attached to its surface, reduce dust attachment, and improve the air intake efficiency;

[0062] In addition, when the heat sink 372 is inclined downward, the moving rod 53 first contacts the round corner 541 of the fan-shaped plate 54, and the round corner 541 pushes the moving rod 53 to slide in the moving groove 52, and at the same time, the moving rod 53 pulls the sliding rod 512 to slide in the contact block 44, so that the knocking column 511 is retracted into the contact block 44 and presses the pressure spring 513, and as the heat sink 372 gradually inclines downward, the filter screen 38 contacts the contact block 44, the moving rod 53 gradually contacts the protruding block 542 and further presses the pressure spring 513, and when the moving rod 53 gradually separates from the contact with the protruding block 542, the pressure spring 513 rebounds to push the knocking column 511 to slide in the inner cavity 51 and knock the frame of the filter screen 38, and the greater the inclination angle of the heat sink 372, the more times the knocking column 511 knocks the filter screen 38, which can further clean the dust on the surface of the filter screen 38.

[0063] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
