Description

TECHNICAL FIELD

[0001] The application relates to the technical field of train circuit breakers, in particular to a redundant control protection device for a main circuit breaker of a heavy-load train. BACKGROUND

[0002] In the field of rail transit, the main circuit breaker, as a core component of the high-voltage system, undertakes the key functions of switching on / off working current and overcurrent protection. In the traditional design, the single circuit breaker has the risk of refusal to act, and the control circuit relies on a single signal channel, which is prone to cause protection failure due to component failure. Therefore, the redundant control protection device significantly improves the system reliability through multi-level redundant design. The redundant control protection device in the redundant control protection device for the main circuit breaker of the heavy-load train serves as a backup circuit breaker of the heavy-load train and undertakes the key functions of replacing the main circuit breaker to switch on / off working current and overcurrent protection when the main circuit breaker fails. At present, the redundant control protection device for the main circuit breaker of the heavy-load train is generally installed on the top of the train. Since the heavy-load train mainly undertakes the transportation task of coal and other goods, and the demand factories of these goods are mostly located in coastal areas, the running line of the heavy-load train is often close to the coast. The salt fog phenomenon frequently occurring in the coastal area poses a threat to the insulating materials, such as insulators, of the redundant control protection device for the main circuit breaker of the heavy-load train. Therefore, these insulating materials must be manually cleaned when the train stops at the station. However, since there are a large number of umbrella skirts on the outer wall of the insulator, and the space between adjacent umbrella skirts is relatively small, the manual cleaning work is time-consuming and laborious. Therefore, the application provides a redundant control protection device for a main circuit breaker of a heavy-load train. SUMMARY

[0003] The application aims to provide a redundant control protection device for a main circuit breaker of a heavy-load train to solve the problems in the background.

[0004] The technical scheme of the application is as follows: a redundant control protection device for a main circuit breaker of a heavy-load train, comprising a backup circuit breaker, a plurality of electric push rods are fixedly installed on the top of the backup circuit breaker, a bottom plate is fixedly installed between the tops of the plurality of electric push rods, a gear ring is rotationally connected to the top of the bottom plate, a shunt plate is communicated on the inner circumferential wall of the gear ring, a plurality of housings are communicated at the bottom of the shunt plate, a second motor is fixedly installed on the side wall of one of the housings, a plurality of cores are fixedly installed on the output shaft of the second motor, a plurality of sponge wipers are fixedly sleeved on the outer circumferential wall of the plurality of cores, and the plurality of sponge wipers are located in the inner cavities of the corresponding housings, respectively. The second motor drives the cores to rotate, and since the sponge wipers are fixedly sleeved on the outer circumferential wall of the cores, the rotating cores drive the sponge wipers to rotate, which to some extent enhances the cleaning effect of the sponge wipers.

[0005] Preferably, the outer peripheral wall of the gear ring is rotatably connected with a ring plate, the outer peripheral wall of the ring plate is communicated with an air inlet pipe and a liquid outlet pipe, the top of the air inlet pipe is communicated with a liquid adding pipe, a plurality of groove holes are equidistantly and circumferentially arranged on the outer peripheral wall of the gear ring, and a plurality of collecting boxes are symmetrically communicated with the two end side walls of the outer shell.

[0006] Preferably, two symmetric knocking rods are slidably arranged on the two end side walls of the outer shell, a top plate is welded to the side of each knocking rod away from the corresponding outer shell, a spring is arranged around the outer peripheral wall of each knocking rod and connected between the corresponding outer shell and top plate, an extension rod is fixedly installed between every two top plates, and two convex tooth rings are fixedly installed on the top of the bottom plate.

[0007] Preferably, two symmetric baffles are welded in the inner cavities of the outer shells, and a cleaning cavity and a drying cavity are separated in the inner cavities of the outer shells.

[0008] Preferably, a filter screen is installed on the gas outlet end of each collecting box, and the filter screen prevents dust from escaping into the surrounding environment.

[0009] Preferably, two symmetric pressing rods are welded in the inner cavities of the outer shells, and the motor two continues to drive the sponge to rotate, and the two symmetric pressing rods can squeeze out the residual acidic solution in the sponge.

[0010] Preferably, a motor one is fixedly installed on the top of the bottom plate, a gear ring-engaging gear is fixedly installed on the output end of the motor one, the motor one drives the gear to rotate, the rotating gear drives the gear ring to rotate due to the engagement between the gear and the gear ring, the rotating gear ring drives the baffle, the outer shell and the sponge to rotate due to the baffle welded on the inner peripheral wall of the gear ring, and the sponge rotating with the gear ring can clean the dust and salt mist between the adjacent two umbrella skirts.

[0011] Preferably, several telescopic airbags are evenly spaced and circumferentially distributed inside the sponge. The telescopic airbags expand under the action of the hot air, and the expanded telescopic airbags push the sponge outward, making the sponge and the pressure rod more tightly abut against each other. This further accelerates the extrusion speed of the acidic solution.

[0012] This invention provides an improved redundant control and protection device for the main circuit breaker of heavy-haul trains, which has the following improvements and advantages compared with the prior art:

[0013] 1. The sponge that rotates with the toothed ring can clean the dust and salt spray between two adjacent skirts. As the moisture in the salt spray gradually evaporates due to heat, the residual salt gradually salts and adheres to the outer surface of the sponge, making the surface of the sponge gradually harden. At this time, the rotating sponge can clean the more stubborn stains between two adjacent skirts. This further enhances the cleaning effect of the sponge on the horizontal insulator.

[0014] 2. Because the sponge has a telescopic airbag inside, the telescopic airbag expands when heated during the hot air drying process. The expanded telescopic airbag pushes the sponge outward, making the outer side of the sponge come into closer contact with the adjacent umbrella skirt. This further enhances the cleaning effect of the sponge on the horizontal insulator.

[0015] 3. As the outer surface of the sponge gradually hardens due to salting, this makes it easier for dust to fall off when the tapping rod strikes the sponge. The dust that falls off is then blown into the collection box by the hot air, thus avoiding pollution of the surrounding environment.

[0016] 4. Hot air is delivered into the inner cavity of the housing through the air inlet pipe. The hot air can agitate the acidic solution, making the acidic solution contact the outer surface of the sponge more evenly. At the same time, the hot air can also heat up the acidic solution, thereby improving the efficiency of the acidic solution in removing salting.

[0017] 5. The telescopic airbag expands under the action of the hot air. The expanded telescopic airbag pushes the sponge outward, making the sponge and the pressure rod more tightly abut against each other. This further accelerates the extrusion of the acidic solution. Attached Figure Description

[0035] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides an improved redundant control and protection device for the main circuit breaker of a heavy-haul train. The technical solution of this invention is as follows:

[0037] like Figures 1-14 As shown, a redundant control and protection device for a main circuit breaker of a heavy-haul train includes a standby circuit breaker 1. Several electric push rods 2 are fixedly mounted on the top of the standby circuit breaker 1. A base plate 3 is fixedly mounted between the tops of the electric push rods 2. A gear ring 4 is rotatably connected to the top of the base plate 3. A motor 26 is fixedly mounted on the top of the base plate 3. A gear 27 meshing with the gear ring 4 is fixedly mounted on the output end of the motor 26. A diverter plate 5 is connected to the inner peripheral wall of the gear ring 4. Several outer shells 6 are connected to the bottom of the diverter plate 5. A second motor 7 is fixedly mounted on the side wall of one of the outer shells 6. Several cores 8 are fixedly mounted on the output shaft of the second motor 7. Sponge wipers 9 are fixedly sleeved on the outer peripheral walls of each of the cores 8, and the sponge wipers 9 are respectively located in the inner cavity of the corresponding outer shell 6. The electric push rod 2 moves the base plate 3 downward, causing the corresponding sponge wiper 9 to move between the two adjacent skirts of the horizontal insulator 28. Then, the motor 1 26 drives the gear 27 to rotate. Since the gear 27 meshes with the gear ring 4, the rotating gear 27 drives the gear ring 4 to rotate. Since the diverter plate 5 is welded to the inner circumferential wall of the gear ring 4, the rotating gear ring 4 drives the diverter plate 5, the outer shell 6, and the sponge wiper 9 to rotate. The sponge wiper 9, which rotates with the gear ring 4, can clean the dust and salt spray between the two adjacent skirts. At the same time, the motor 2 7 drives the core 8 to rotate. Since the sponge wiper 9 is fixedly sleeved on the outer circumferential wall of the core 8, the rotating core 8 drives the sponge wiper 9 to rotate. This enhances the cleaning effect of the sponge wiper 9 to a certain extent.

[0038] Furthermore, a ring plate 10 is rotatably connected to the outer peripheral wall of the gear ring 4. An air inlet pipe 11 and a liquid outlet pipe 12 are connected to the outer peripheral wall of the ring plate 10. A liquid inlet pipe 13 is connected to the top of the air inlet pipe 11. Several slots 14 are circumferentially opened at equal intervals on the outer peripheral wall of the gear ring 4. Two symmetrical partitions 21 are welded to the inner cavities of several outer shells 6. The inner cavities of several outer shells 6 are divided into a cleaning chamber 22 and a drying chamber 23. Two symmetrical partitions 21 are connected to the side walls at both ends of several outer shells 6. When in use, the external hot air assembly of the collection box 15 delivers hot air into the air inlet pipe 11. Since the air inlet pipe 11 is connected to the ring plate 10, and several equally spaced circumferential slots 14 are provided on the outer peripheral wall of the gear ring 4, the slots 14 on the outer peripheral wall of the gear ring 4 intermittently align with the air inlet pipe 11 as the gear ring 4 rotates. During this process, hot air enters the inner cavity of the gear ring 4 through the slots 14. Because the diverter plate 5 is connected to the inner cavity of the gear ring 4, the hot air passes through... The diverter plate 5 enters the drying chamber 23 inside the outer casing 6, where hot air dries the sponge 9 during the cleaning process. As the moisture in the salt spray gradually evaporates due to the heat, the residual salt gradually salts and adheres to the outer surface of the sponge 9, causing the surface of the sponge 9 to gradually harden. At this time, the rotating sponge 9 can clean the more stubborn stains between two adjacent skirts, which further enhances the cleaning effect of the sponge 9 on the horizontal insulator 28. Among them, several sponge 9s have several telescopic airbags 29 evenly spaced circumferentially distributed inside. Due to the telescopic airbags 29 inside the sponge 9, during the hot air drying process, the telescopic airbags 29 expand due to the heat. The expanded telescopic airbags 29 push the sponge 9 outward, making the outer side of the sponge 9 more tightly contact the adjacent skirts. This further enhances the cleaning effect of the sponge 9 on the horizontal insulator 28.

[0039] Furthermore, two symmetrical striking rods 16 are slidably mounted on the sidewalls at both ends of several outer shells 6. A top plate 17 is welded to the side of each striking rod 16 away from its corresponding outer shell 6. A spring 18 is wound around the outer periphery of each striking rod 16, connecting the corresponding outer shell 6 to the corresponding top plate 17. An extension rod 19 is fixedly installed between each set of top plates 17. Two toothed rings 20 are fixedly installed on the top of the bottom plate 3. The striking rods 16 and extension rods 19 rotate with the outer shell 6. Since the two ends of the extension rod 19 rest on the outer wall of the corresponding toothed ring 20, and since one side of the toothed ring 20's outer surface is inclined and the other side is vertical, the extension rod 19... Sliding along the inclined surface of the toothed ring 20 to the top of the tooth, when it moves to the side of the vertical plane, the extension rod 19 is quickly dropped by the elastic force of the spring 18. As the extension rod 19 rotates with the outer shell 6, it drives the striking rod 16 to intermittently strike the outside of the sponge 9, thereby cleaning the dust from the outside of the dried sponge 9. At the same time, as the outer surface of the sponge 9 gradually hardens due to salting, this makes it easier for the dust on the outer surface to fall off when the striking rod 16 strikes the sponge 9. The air outlets at both ends of several collection boxes 15 are equipped with filters 24. The dust that falls off enters the collection box 15 under the blowing of hot air, thus avoiding pollution to the surrounding environment.

[0040] Furthermore, each of the inner cavities of the outer shell 6 is welded with two symmetrical pressure rods 25. The motor 7 continues to drive the sponge 9 to rotate. The two symmetrically arranged pressure rods 25 can squeeze out the acidic solution remaining in the sponge 9. At the same time, the telescopic airbag 29 expands under the action of the hot air. The expanded telescopic airbag 29 pushes the sponge 9 outward, making the sponge 9 and the pressure rods 25 more tightly abut against each other. This further accelerates the squeezing out of the acidic solution.

[0041] Working principle: During use, the electric push rod 2 moves the base plate 3 downward, causing the corresponding sponge wiper 9 to move between the two adjacent skirts of the horizontal insulator 28. Then, the motor 26 drives the gear 27 to rotate. Since the gear 27 meshes with the gear ring 4, the rotating gear 27 drives the gear ring 4 to rotate. Because the diverter plate 5 is welded to the inner circumferential wall of the gear ring 4, the rotating gear ring 4 drives the diverter plate 5, the outer shell 6, and the sponge wiper 9 to rotate. The sponge wiper 9, which rotates with the gear ring 4, can remove dust and salt spray between the two adjacent skirts. The cleaning process is as follows: Simultaneously, the motor 7 drives the core 8 to rotate. Since the sponge 9 is fixedly mounted on the outer wall of the core 8, the rotating core 8 causes the sponge 9 to rotate, which enhances the cleaning effect of the sponge 9 to some extent. Furthermore, the air inlet pipe 11 is connected to an external hot air assembly. During use, the external hot air assembly supplies hot air into the air inlet pipe 11. Because the air inlet pipe 11 is connected to the ring plate 10, and the outer wall of the toothed ring 4 has several equally spaced circumferentially spaced slots 14, the toothed ring... 4. During rotation, the slots 14 on its outer peripheral wall intermittently align with the air inlet pipe 11. During this process, hot air enters the inner cavity of the gear ring 4 through the slots 14. Since the diverter plate 5 is connected to the inner cavity of the gear ring 4, the hot air enters the drying chamber 23 inside the outer shell 6 through the diverter plate 5. The hot air can be used to dry the sponge 9 during the cleaning process. As the moisture in the salt spray gradually evaporates due to heat, the residual salt gradually salts and adheres to the outer surface of the sponge 9, causing the surface of the sponge 9 to gradually harden. At this time, the rotation and air inlet... The self-rotating sponge 9 can clean stubborn stains between two adjacent skirts, which further enhances the cleaning effect of the sponge 9 on the horizontal insulator 28. At the same time, since the sponge 9 is equipped with a telescopic air bladder 29, the telescopic air bladder 29 expands when heated during the hot air drying process. The expanded telescopic air bladder 29 pushes the sponge 9 outward, making the outer side of the sponge 9 more tightly in contact with the adjacent skirt. This further enhances the cleaning effect of the sponge 9 on the horizontal insulator 28.

[0042] Subsequently, the striking rod 16 and the extension rod 19 rotate with the outer casing 6. Since the two ends of the extension rod 19 rest on the outer wall of the corresponding toothed ring 20, and since one side of the toothed ring 20 is inclined and the other side is vertical, the extension rod 19 slides along the inclined side of the toothed ring 20 to the top of the toothed ring. When it moves to the vertical side, the extension rod 19 falls quickly under the elastic force of the spring 18. As the extension rod 19 rotates with the outer casing 6, it causes the striking rod 16 to intermittently strike the outside of the sponge 9, thereby cleaning the dust from the outside of the dried sponge 9. At the same time, as the outer surface of the sponge 9 gradually hardens due to salting, this makes it easier for the dust on the outer surface to fall off when the striking rod 16 strikes the sponge 9. The dust that falls off enters the collection box 15 under the blowing of hot air, thus avoiding pollution of the surrounding environment.

[0043] After cleaning, the first motor 26 drives the housing and sponge 9 to flip to the bottom of the inner circumferential wall of the gear ring 4. Then, the electric push rod 2 moves the base plate 3 downward to prevent the sponge 9 from touching the horizontal insulator 28. An acidic solution is supplied to the inner cavity of the housing 6 through the liquid supply pipe 13. It should be noted that the acidic solution should not be too much; it should only be in contact with the bottom of the flipped sponge 9. Subsequently, the second motor 7 drives the sponge 9 to rotate, so that the outer surface of the sponge 9 is in uniform contact with the acidic solution, thereby removing the salting on the outer surface of the sponge 9. During this process, hot air is supplied to the inner cavity of the housing through the air inlet pipe 11. The hot air can agitate the acidic solution, making the contact between the acidic solution and the outer surface of the sponge 9 more uniform. At the same time, the hot air can also remove the acid. The acidic solution is heated to accelerate the removal of salt stains. After the salt stains are removed, the drain pipe 12 is opened, and the acidic solution in the inner cavity of the outer shell 6 is discharged through the drain pipe 12. Meanwhile, the motor 7 continues to drive the sponge 9 to rotate, and the two symmetrically arranged pressure rods 25 squeeze out the remaining acidic solution from the sponge 9. At the same time, the telescopic airbag 29 expands under the action of the hot air, and the expanded telescopic airbag 29 pushes the sponge 9 outward, making the sponge 9 and the pressure rods 25 more tightly abut against each other, which further accelerates the extrusion speed of the acidic solution. Finally, clean water is added to the inner cavity of the shell through the liquid filling pipe 13, and the above operation is repeated to complete a relatively thorough cleaning of the sponge 9.
