Description

Technical Field

[0001] The present invention relates to the technical field of distribution network automation emergency repair devices, and specifically relates to an island distribution network automation emergency repair device. Background Art

[0002] When a circuit distribution network built on an island with inconvenient transportation has a line fault, it is often difficult for emergency repair personnel to arrive in time due to inconvenient transportation. Especially in bad weather such as strong winds and heavy fog, it is even more difficult for emergency repair personnel to arrive in time, resulting in the expansion of line faults and low operation and maintenance efficiency. To solve this problem, currently, the method of "whole-line installation" is adopted on the primary branch lines and secondary branch lines of the distribution network to install intelligent switch control boxes. Once a power outage fault occurs, emergency repair personnel cannot go to the island to handle the fault in the first place. The dispatcher initially judges the fault through the distribution automation master station system, determines the fault point, and then remotely controls the intelligent switch control box to isolate the fault and restore power supply, reducing the fault power outage time.

[0003] The existing intelligent switch control boxes are installed on the primary branch lines and secondary branch lines, resulting in them often being exposed to the outside and only relying on their own boxes for protection. In daily weather, they are easily nested by birds. In stormy weather, at extremely high wind speeds, they are easily mixed with sundries such as branches and stones, resulting in high-speed airflows mixed with impurities hitting the surface of the control box. And the control box relying only on its own box for protection is too weak.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an island distribution network automation emergency repair device is proposed. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an island distribution network automation emergency repair device, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An island distribution network automation emergency repair device includes a control box body and a wind vane protection component. A rotating shaft is provided at the top of the control box body, and the wind vane protection component is connected to the top of the rotating shaft. The wind vane protection component includes a transverse rod, a wind vane tail, a protection panel, an arc-shaped chute, a spring, an extension plate, and a wind-receiving piece. One end of the transverse rod is fixed with a wind vane tail, and the other end of the transverse rod is fixed with a protection panel. Arc-shaped chutes are provided on both sides of the surface of the protection panel, and a spring is provided inside the arc-shaped chute. One end of the spring is fixed with an extension plate, and wind-receiving pieces are distributed on the surface of the extension plate.

[0007] Further, the extension plate is slidably connected to the protection panel through the arc-shaped chute, and both the extension plate and the protection panel are in an arc-shaped structure.

[0008] Furthermore, a base component is provided at the bottom of the control box body. The base component includes a base, a rotating output shaft, and a transmission belt. The rotating output shafts are rotatably connected to the periphery of the surface of the base, and the transmission belt is meshed with the outer wall of the top of the rotating output shaft.

[0009] Furthermore, the base component further includes a moving seat and a cleaning roller. The moving seat is fixed to the outer surface of the transmission belt, and the cleaning roller is rotatably connected to the top of the moving seat.

[0010] Furthermore, a cleaning sponge sleeve is sleeved on the outer surface of the cleaning roller, and the cleaning sponge sleeve is attached to the outer surface of the control box body.

[0011] Furthermore, the base component further includes a transmission gear shaft. The transmission gear shafts are fixed to the bottom of the two cleaning rollers on the same side, and the transmission gear shafts are located inside the base.

[0012] Furthermore, the base component further includes a first upper gear shaft, a first one-way ratchet sleeve, and a first lower gear shaft. One side of the bottom of any one of the transmission gear shafts is meshed with the first lower gear shaft, the top of the first lower gear shaft is connected with the first one-way ratchet sleeve, and the top of the first one-way ratchet sleeve is connected with the first upper gear shaft.

[0013] Furthermore, the base component further includes a second upper gear shaft, a second one-way ratchet sleeve, a bevel gear box, and a second lower gear shaft. One side of the bottom of the other transmission gear shaft is meshed with the second lower gear shaft, the top of the second lower gear shaft is connected with the bevel gear box, the top of the bevel gear box is connected with the second one-way ratchet sleeve, and the top of the second one-way ratchet sleeve is connected with the second upper gear shaft.

[0014] Furthermore, the second upper gear shaft and the first upper gear shaft are both located outside the transmission belt, and the distance between the second upper gear shaft, the first upper gear shaft and the transmission belt is greater than the outer diameter of the cleaning roller.

[0015] Furthermore, the outer sides of the second upper gear shaft and the first upper gear shaft are meshed with an internal gear ring, and the internal gear ring is fixed to the inner side bottom of the protection panel.

[0016] The present invention provides an automatic repair device for island power distribution network, which has the following beneficial effects: 1. For this automatic repair device for island power distribution network, the wind generated in the natural environment is utilized to make the wind vane deflect with the wind direction, so that the protection panel is always facing the wind. Thus, in daily weather, birds can be driven away to prevent birds from building nests, and in strong wind weather, high-speed airflow containing sundries can be prevented from hitting the surface of the control box body. Moreover, as the wind speed increases, the expansion plates extend from both sides of the protection panel, thereby increasing the protection area of the protection panel, and thus improving the protection effect on the control box body in severe strong wind weather.

[0017] 2. The island distribution network automation emergency repair device uses the force generated when the internal gear ring rotates clockwise or counterclockwise or continuously swings with the deflection of the wind direction following the protective panel to drive the rotation of the second upper gear shaft and the first upper gear shaft. Through the second one-way ratchet sleeve, the first one-way ratchet sleeve and the bevel gear box, the first lower gear shaft and the second lower gear shaft drive the two rotating output shafts to always rotate in the same direction. As a result, the cleaning roller moves cyclically along with the conveyor belt and cleans the surface of the control box body to prevent dust adhesion from affecting the communication effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] Such as Figures 1 - 7As shown in the figure, the present invention provides a technical solution: an automatic repair device for island distribution network, including a control box body 1 and a wind vane protection component 3. A rotating shaft 2 is provided at the top of the control box body 1, and the wind vane protection component 3 is connected to the top of the rotating shaft 2. The wind vane protection component 3 includes a horizontal rod 301, a wind vane 302, a protection panel 303, an arc-shaped chute 304, a spring 305, an extension plate 306 and a wind-receiving piece 307. A wind vane 302 is fixed at one end of the horizontal rod 301, and a protection panel 303 is fixed at the other end of the horizontal rod 301. Arc-shaped chutes 304 are provided on both sides of the surface of the protection panel 303, and a spring 305 is arranged inside the arc-shaped chutes 304. One end of the spring 305 is fixed with an extension plate 306, and wind-receiving pieces 307 are distributed on the surface of the extension plate 306. The extension plate 306 is slidably connected to the protection panel 303 through the arc-shaped chute 304, and both the extension plate 306 and the protection panel 303 are in an arc-shaped structure; The specific operation is as follows. The control box body 1 is installed on the upper part of the electric pole and is connected to the primary branch line and the secondary branch line through wires. The wires are led out from the bottom of the control box body 1. In normal weather, the wind vane 302 deflects with the wind direction, so that the horizontal rod 301 drives the protection panel 303 to rotate around the control box body 1, making the outer arc surface of the protection panel 303 face the wind. The rotation of the protection panel 303 and the horizontal rod 301 can drive away birds to prevent birds from building nests on the surface of the control box body 1; In strong wind weather, the protection panel 303 is arranged facing the wind under the action of the wind vane 302 deflecting with the wind direction. At this time, the high-speed airflow and the impurities contained therein will be blocked by the extension plate 306, thereby preventing the high-speed airflow containing impurities from hitting the surface of the control box body 1. As the wind speed increases, when the force received by the wind-receiving piece 307 is greater than the elasticity of the spring 305, the spring 305 is compressed and the wind-receiving piece 307 pushes the extension plate 306 to slide along the inside of the arc-shaped chute 304, so that the extension plate 306 extends out from both sides of the protection panel 303, thereby increasing the protection area of the protection panel 303; Among them, whether to make a microporous design on the surface of the protection panel 303 is selected according to the local wind force level. The microporous protection panel 303 is convenient for the wind to pass through while blocking impurities under the action of high-level wind force, so as to reduce the bearing capacity of the protection panel 303 in a high-level wind force environment; Based on the above description, the present invention utilizes the wind generated in the natural environment to cause the wind vane 302 to deflect with the wind direction, so that the protection panel 303 is always facing the wind, thereby expelling birds and preventing birds from building nests in daily weather, and preventing high-speed airflow containing sundries from hitting the surface of the control box body 1 in strong wind weather. Moreover, as the wind speed increases, the extension plates 306 extend from both sides of the protection panel 303, thereby increasing the protection area of the protection panel 303, and thus improving the protection effect on the control box body 1 in severe strong wind weather.

[0022] As Figures 1 - 7 shown, a base assembly 4 is provided at the bottom of the control box body 1. The base assembly 4 includes a base 401, a rotating output shaft 402 and a transmission belt 403. The rotating output shaft 402 is rotatably connected to the periphery of the surface of the base 401, and the outer wall of the top of the rotating output shaft 402 is meshed with the transmission belt 403. The base assembly 4 further includes a moving seat 404 and a cleaning roller 405. The moving seat 404 is fixed on the outer surface of the transmission belt 403, and the cleaning roller 405 is rotatably connected to the top of the moving seat 404. A cleaning sponge sleeve is sleeved on the outer surface of the cleaning roller 405, and the cleaning sponge sleeve is attached to the outer surface of the control box body 1. The base assembly 4 further includes a transmission gear shaft 406. The bottom of both cleaning rollers 405 on the same side is fixed with a transmission gear shaft 406, and the transmission gear shaft 406 is located inside the base 401. The base assembly 4 further includes a first upper gear shaft 407, a first one-way ratchet sleeve 408 and a first lower gear shaft 409. One side of the bottom of any transmission gear shaft 406 is meshed with the first lower gear shaft 409, and the top of the first lower gear shaft 409 is connected with the first one-way ratchet sleeve 408. The top of the first one-way ratchet sleeve 408 is connected with the first upper gear shaft 407. The base assembly 4 further includes a second upper gear shaft 410, a second one-way ratchet sleeve 411, a bevel gear box 412 and a second lower gear shaft 413. One side of the bottom of the other transmission gear shaft 406 is meshed with the second lower gear shaft 413, and the top of the second lower gear shaft 413 is connected with the bevel gear box 412. The top of the bevel gear box 412 is connected with the second one-way ratchet sleeve 411, and the top of the second one-way ratchet sleeve 411 is connected with the second upper gear shaft 410. The second upper gear shaft 410 and the first upper gear shaft 407 are both located outside the transmission belt 403, and the distance between the second upper gear shaft 410, the first upper gear shaft 407 and the transmission belt 403 is greater than the outer diameter of the cleaning roller 405. The outer sides of the second upper gear shaft 410 and the first upper gear shaft 407 are meshed with an internal gear ring 5, and the internal gear ring 5 is fixed to the inner side bottom of the protection panel 303; The specific operation is as follows. When the protection panel 303 rotates clockwise or counterclockwise with the deflection of the wind direction, the internal gear ring 5 rotates synchronously. When the internal gear ring 5 continuously changes its swing or rotation clockwise or counterclockwise, it will drive the second upper gear shaft 410 and the first upper gear shaft 407 to rotate. When the second upper gear shaft 410 and the first upper gear shaft 407 rotate clockwise, the second one-way ratchet sleeve 411 causes the second lower gear shaft 413 not to rotate with the second upper gear shaft 410, while the first upper gear shaft 407 causes the first lower gear shaft 409 to rotate through the first one-way ratchet sleeve 408. When the second upper gear shaft 410 and the first upper gear shaft 407 rotate counterclockwise, the first one-way ratchet sleeve 408 causes the first lower gear shaft 409 not to rotate with the first upper gear shaft 407, while the second upper gear shaft 410 causes the three bevel gears meshing perpendicularly inside the bevel gear box 412 to rotate through the second one-way ratchet sleeve 411, and the bevel gears drive the second lower gear shaft 413 to rotate. Among them, the second lower gear shaft 413 and the first lower gear shaft 409 rotate in the same direction. Thus, during the process of the internal gear ring 5 continuously changing its swing clockwise or counterclockwise, the rotating output shaft 402 can rotate in the same direction, thereby enabling the belt 403 to perform a one-way cyclic drive, so that the cleaning roller 405 can clean the surface of the control box body 1 during the cyclic movement to prevent dust adhesion from affecting the communication effect; Based on the above description, when the internal gear ring 5 rotates or continuously changes its swing clockwise or counterclockwise following the deflection of the wind direction of the protection panel 303, the acting force is used to push the second upper gear shaft 410 and the first upper gear shaft 407 to rotate. Also, through the second one-way ratchet sleeve 411, the first one-way ratchet sleeve 408 and the bevel gear box 412, the first lower gear shaft 409 and the second lower gear shaft 413 drive the two rotating output shafts 402 to always be able to rotate in the same direction. Thus, the cleaning roller 405 moves cyclically with the belt 403 and cleans the surface of the control box body 1 to prevent dust adhesion from affecting the communication effect.

[0023] In summary, for this island power distribution automation emergency repair device, during use, first, the control box body 1 is installed on the upper part of the electric pole and is connected to the primary branch line and the secondary branch line through wires. The wires are led out from the bottom of the control box body 1. In normal weather, the wind vane 302 deflects with the wind direction, causing the cross bar 301 to carry the protection panel 303 to rotate around the control box body 1, making the outer arc surface of the protection panel 303 face the wind. The rotation of the protection panel 303 and the cross bar 301 can drive away birds to prevent birds from building nests on the surface of the control box body 1; In windy weather, the protection panel 303 is arranged facing the wind under the action of the wind-direction fin 302 deflecting with the wind direction. At this time, the high-speed airflow and the impurities contained therein will be blocked by the expansion plate 306, thereby preventing the high-speed airflow with impurities from hitting the surface of the control box body 1. As the wind speed increases, when the wind-receiving piece 307 is stressed and the force it receives is greater than the elasticity of the spring 305, the spring 305 is compressed and the wind-receiving piece 307 pushes the expansion plate 306 to slide along the inner part of the arc-shaped chute 304, so that the expansion plate 306 extends from both sides of the protection panel 303, thereby increasing the protection area of the protection panel 303; When the protection panel 303 rotates clockwise or counterclockwise with the wind direction deflection, the internal gear ring 5 rotates synchronously. When the internal gear ring 5 continuously changes its swing or rotation clockwise or counterclockwise, it will drive the second upper gear shaft 410 and the first upper gear shaft 407 to rotate. When the second upper gear shaft 410 and the first upper gear shaft 407 rotate clockwise, the second one-way ratchet sleeve 411 makes the second lower gear shaft 413 not rotate with the second upper gear shaft 410, while the first upper gear shaft 407 makes the first lower gear shaft 409 rotate through the first one-way ratchet sleeve 408. When the second upper gear shaft 410 and the first upper gear shaft 407 rotate counterclockwise, the first one-way ratchet sleeve 408 makes the first lower gear shaft 409 not rotate with the first upper gear shaft 407, while the second upper gear shaft 410 makes the three bevel gears meshing perpendicularly inside the bevel gear box 412 rotate through the second one-way ratchet sleeve 411, and the bevel gears drive the second lower gear shaft 413 to rotate. The second lower gear shaft 413 and the first lower gear shaft 409 rotate in the same direction. Thus, during the process of the internal gear ring 5 continuously changing its swing clockwise or counterclockwise, the rotation output shaft 402 can rotate in the same direction, so that the transmission belt 403 performs a one-way cyclic transmission, so that the cleaning roller 405 can clean the surface of the control box body 1 during the cyclic movement.
