Description

Technical Field

[0001] This application relates to the technical field of primary and secondary integrated ring network boxes, and in particular to an intelligent and environmentally friendly primary and secondary integrated ring network box. Background Technology

[0002] The integrated primary and secondary ring main unit is a key piece of equipment used in power distribution networks. It deeply integrates traditionally separate primary equipment (such as circuit breakers, high-voltage switches, and instrument transformers) and secondary equipment (such as protection devices, measuring devices, and communication devices) into a sealed enclosure to build a more efficient and reliable power distribution network.

[0003] In related technologies, the primary and secondary integrated ring main unit includes a box body with a door rotatably connected to the box body. The box body has a placement slot for placing the ring main unit. The ring main unit contains electrical components with different functions. The box body has multiple ventilation holes for heat dissipation.

[0004] When the primary and secondary integrated ring main unit is installed next to the railway and in a high-dust environment, the high-speed trains will cause the air around the unit to flow rapidly, causing dust to enter the unit through the ventilation holes with the strong wind. The large amount of dust accumulated inside the unit will affect the electrical components. Summary of the Invention

[0005] To improve upon this, this application provides an intelligent and environmentally friendly integrated primary and secondary ring network box.

[0006] This application provides an intelligent and environmentally friendly integrated primary and secondary ring network box, which adopts the following technical solution: A smart and environmentally friendly primary and secondary integrated ring network box includes a box body with a ventilation box on the box body. The ventilation box has ventilation holes connecting the box body and the outside air. The ventilation box has an air duct communicating with the ventilation holes. A fixing plate is provided in the air duct. Adhesive tape for adhering to dust is rotatably connected to the fixing plate. When the adhesive tape is unfolded, it is located on the movement path of the gas entering the air duct. When a strong wind enters the ventilation hole, the strong wind first adsorbs dust through the adhesive tape and then enters the box body through the air duct.

[0007] By adopting the above technical solution, when strong winds enter the ventilation holes, the tape, after being unfurled, is positioned on the movement path of the gas entering the air duct. This allows the dust carried in the strong winds to be absorbed by the tape before entering the housing through the air duct, reducing the possibility of dust entering the housing. This avoids a large amount of dust accumulating inside the housing, reducing dust pollution and chemical corrosion to key equipment such as the internal ring main unit, extending the service life of the equipment, and ensuring long-term stable operation. This allows the ring main unit to block a large amount of dust brought by strong winds even in high-dust environments such as mines and industrial areas, further improving the environmental adaptability and operational reliability of the ring main unit.

[0008] Optionally, a slider is slidably connected to the fixed plate, a drive spring is provided on the slider, a fixed block is provided on the drive spring, and a fixed magnet is provided on the fixed block. A first magnet and a second magnet are provided inside the ventilation box. The first magnet attracts the fixed magnet, and the second magnet repels the fixed magnet. When strong wind enters the ventilation hole, the fixed block abuts against the tape. The fixed block is located between the first magnet and the second magnet, and the fixed block drives the tape to move along the direction of the second magnet towards the first magnet.

[0009] By adopting the above technical solution, when strong winds enter the ventilation hole, the strong winds push the fixing block towards the tape, allowing the fixing block to come into contact with the tape. Through the attraction of the first magnet to the fixing magnet and the repulsion of the second magnet to the fixing magnet, the fixing block can drive the tape to move along the direction of the second magnet towards the first magnet, so as to automatically replace the tape when strong winds intrude, without the need for external power or manual intervention. The fixing block pulls out the new tape, thereby ensuring the tape's ability to adsorb dust, reducing the possibility of dust entering the housing from the air duct, and further improving the long-term operational reliability and maintenance-free level of the equipment in high dust and strong wind environments.

[0010] Optionally, the first magnet is provided with a third magnet that repels the fixed magnet, and the second magnet is provided with a fourth magnet that attracts the fixed magnet; when the wind weakens, the fixed block moves away from the tape under the force of the drive spring, and the fixed block is located between the third magnet and the fourth magnet. The fixed block moves along the direction of the third magnet towards the fourth magnet to achieve reset.

[0011] By adopting the above technical solution, when the strong wind weakens, the drive spring can drive the fixed block to move away from the conveyor belt, allowing the fixed magnet to enter between the third and fourth magnets. Through the repulsive force of the third magnet and the attractive force of the fourth magnet, the fixed block is driven to move along the direction where the third magnet is closer to the fourth magnet, thereby realizing the reset of the fixed block. This prepares for the automatic belt changing action when the next strong wind arrives, ensuring that the equipment can continuously and automatically maintain a high-efficiency dust filtration state in environments with intermittent strong winds or frequent wind changes, further enhancing the intelligent self-maintenance capability and long-term operational stability of the ring main unit.

[0012] Optionally, the fixing plate is provided with a guide block, and the guide block is provided with a guide slope. The distance from the guide slope to the fixing plate gradually increases along the direction of the second magnet approaching the first magnet. The guide slope is used to separate the fixing block and the tape.

[0013] By adopting the above technical solution, the distance from the guide slope to the fixing plate gradually increases along the direction of the second magnet closer to the first magnet, so that the fixing block can smoothly and gradually separate from the tape along the direction of the guide slope. This prevents the problem of the drive spring suddenly releasing and causing the fixing block to return to its position quickly when the wind weakens, which would cause the tape to be suddenly and at high speed to be pulled off the attachment surface. This reduces the risk of the tape accidentally falling off or being damaged, and enhances the reliability and stability of the device.

[0014] Optionally, the ventilation box is equipped with a rotating shaft for collecting waste tape, the rotating shaft is equipped with a gear, and a rack that meshes with the gear is slidably connected inside the ventilation box. The fixing block is equipped with a toothed block that meshes with the rack. When the fixing block abuts against the tape, the toothed block meshes with the rack, and the fixing block drives the rotating shaft to rotate through the rack to achieve the winding of the waste tape.

[0015] By adopting the above technical solution, when the fixing block comes into contact with the tape, the toothed block and the rack mesh, so that the fixing block can synchronously drive the rack to slide along the ventilation box during the movement. The rack can drive the meshing gear to rotate, thereby converting the linear motion of the fixing block into the rotational motion of the shaft. This enables the shaft to continuously and stably wind up the used tape, so that the waste tape can be collected in a timely and automatic manner, avoiding the accumulation or scattering of tape in the ventilation box, keeping the inside of the device clean, and reducing the frequency of manual cleaning, thereby further improving the automation level and maintenance convenience of the device.

[0016] Optionally, the rack is configured as a ring, and the rack rotates around its own circumference; when the fixing block is disengaged from the tape, the rack is disengaged from the toothed block.

[0017] By adopting the above technical solution, and by setting the rack to be ring-shaped and able to rotate around its own circumference, the rack forms a continuous transmission track. When the fixed block abuts the tape, the toothed block meshes with the ring-shaped rack, driving the rack to rotate cyclically. When the fixed block disengages from the tape, the toothed block and the rack automatically disengage. This not only achieves reliable transmission and timely separation between the fixed block and the winding mechanism, but also ensures that the rotating shaft only winds up when the tape is fixed, thereby avoiding malfunctions and energy waste. At the same time, the continuous structure of the ring-shaped rack reduces impact and wear during transmission, and improves the adaptability of the winding process and the stability of system operation.

[0018] Optionally, the ventilation box includes a base and a top cover, the top cover being detachably connected to the base, and a receiving cavity being formed on the surface of the base near the top cover.

[0019] By adopting the above technical solution, the top cover can be detachably connected to the base, allowing staff to remove the top cover to directly clean, maintain, or replace the tape in the housing and internal structure. The housing provides a centralized and stable installation and operating space for related functional components, effectively optimizing the internal layout of the enclosure, while improving the convenience and efficiency of equipment assembly and daily maintenance.

[0020] Optionally, the ventilation box has an installation slot for placing the tape. The slot wall has a groove, and a positioning spring is provided in the groove. The positioning spring has a fixed shaft for rotating the tape, and an operating block is provided on the fixed shaft. When the operating block slides away from the tape, the fixed shaft exits the installation slot, and the tape can be replaced.

[0021] By adopting the above technical solution, the mounting groove provides a dedicated positioning space for the tape, and the positioning spring in the groove supports the fixed shaft with its elasticity, allowing the tape to be stably installed and rotate flexibly on the fixed shaft. When the tape needs to be replaced, the fixed shaft can be pushed out of the mounting groove by sliding the operating block to overcome the elasticity of the positioning spring, so that the tape can be quickly removed or installed. This makes the installation and removal of the tape convenient, avoids the cumbersome installation and removal problems of traditional fixing methods, and improves the efficiency of tape replacement. At the same time, the continuous pressing action of the positioning spring also ensures the stability and positional accuracy of the tape during operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When strong winds enter the ventilation openings, the tape, once unfurled, lies on the path of the gas entering the duct. This allows dust carried by the strong winds to be absorbed by the tape before entering the housing through the duct, reducing the likelihood of dust entering the housing. This prevents large amounts of dust from accumulating inside the housing, reducing dust pollution and chemical corrosion to critical equipment such as the internal ring main unit, extending the equipment's service life, and ensuring long-term stable operation. Even in high-dust environments such as mines and industrial areas, the ring main unit can block large amounts of dust brought by strong winds from intruding, further improving its environmental adaptability and operational reliability.

[0023] When strong winds enter the ventilation opening, they push the fixing block towards the tape, allowing it to contact the tape. Through the attraction of the first magnet to the fixing magnet and the repulsion of the second magnet to the fixing magnet, the fixing block moves the tape along the direction where the second magnet is closer to the first magnet. This enables automatic tape replacement when strong winds intrude, without external power or manual intervention. The fixing block pulls out the new tape, ensuring the tape's ability to adsorb dust and reducing the possibility of dust entering the housing from the air duct. This further improves the long-term operational reliability and maintenance-free level of the equipment in high-dust and strong-wind environments. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0027] This embodiment discloses an intelligent and environmentally friendly integrated primary and secondary ring network box. (Refer to...) Figure 1 and Figure 2 A smart and environmentally friendly primary and secondary integrated ring main unit includes a housing 1. The housing 1 is coated with an environmentally friendly coating, which has excellent corrosion resistance and weather resistance, extending the service life of the housing 1. This reduces the energy and raw materials consumed in production, transportation, and installation of new equipment due to premature corrosion and scrapping, as well as the waste generated from the disposal of old equipment. Simultaneously, the environmentally friendly coating does not emit harmful gases into the atmosphere, improving the air quality of the surrounding environment. A ventilation box 2 is fixedly connected to the side surface of the housing 1. Ventilation holes 21 connecting the housing 1 to external air are opened on the surface of the ventilation box 2 away from the housing 1. An air duct 22 communicating with the ventilation holes 21 is opened inside the ventilation box 2. A fixing plate 23 is fixedly connected inside the air duct 22. Adhesive tape 24 for adhering to dust is rotatably connected to the surface of the fixing plate 23 near the ventilation holes 21. When the tape 24 is unfolded, it is positioned on the path of the gas entering the air duct 22. When strong wind enters the ventilation holes 21, the strong wind first adsorbs dust through the tape 24 before entering the housing 1 through the air duct 22.

[0028] Reference Figure 2 and Figure 3A sliding groove 231 is formed on the surface of the fixing plate 23 near the ventilation hole 21, and a slider 232 is slidably connected in the sliding groove 231. A drive spring 233 is fixedly connected to the bottom wall of the slider 232 away from the sliding groove 231, and a fixing block 25 is fixedly connected to the other end face of the drive spring 233. A fixing magnet 251 is fixedly connected to the outer surface of the fixing block 25, and a first magnet 252 and a second magnet 253 are fixedly connected inside the ventilation box 2. The first magnet 252 and the second magnet 253 are located on opposite sides of the fixing block 25. The first magnet 252 attracts the fixing magnet 251, and the second magnet 253 repels the fixing magnet 251.

[0029] Reference Figure 2 and Figure 3 When a strong wind enters the ventilation hole 21, the gas drives the fixing block 25 to move towards the tape 24, so that the fixing block 25 sticks to the tape 24. At this time, the fixing block 25 is located between the first magnet 252 and the second magnet 253. The fixing block 25 can drive the tape 24 to move along the direction of the second magnet 253 towards the first magnet 252 until the fixing magnet 251 is attracted to the first magnet 252. At this time, the fixing block 25 realizes the replacement of the tape 24.

[0030] Reference Figure 3 A third magnet 254, which repels the fixed magnet 251, is fixedly connected to the surface of the first magnet 252 away from the tape 24. A fourth magnet 255, which attracts the fixed magnet 251, is fixedly connected to the surface of the second magnet 253 away from the tape 24. When the wind weakens, the fixing block 25 moves away from the tape 24 under the force of the drive spring 233. The fixing block 25 is located between the third magnet 254 and the fourth magnet 255. The fixing block 25 moves along the direction of the third magnet 254 towards the fourth magnet 255 to achieve a reset.

[0031] Reference Figure 3 A guide block 26 is fixedly connected to the fixed plate 23. A guide slope 261 is provided on the surface of the guide block 26 away from the fixed plate 23. The distance from the guide slope 261 to the fixed plate 23 gradually increases along the direction of the second magnet 253 approaching the first magnet 252. The fixed block 25 can be separated from the tape 24 along the inclined direction of the guide slope 261.

[0032] Reference Figure 2 and Figure 3A rotating shaft 27 for collecting waste tape 24 is fixedly connected inside the ventilation box 2. A gear 271 is fixedly connected to the outer surface of the rotating shaft 27. A rack 272, which meshes with the gear 271, is slidably connected inside the ventilation box 2. The rack 272 is ring-shaped and rotates around its circumference. A toothed block 256 that meshes with the rack 272 is fixedly connected to the surface of the fixing block 25 near the tape 24. When the fixing block 25 abuts against the tape 24, the toothed block 256 meshes with the rack 272. The sliding process of the fixing block 25 drives the rack 272 to rotate synchronously. The rack 272 can drive the rotating shaft 27 to rotate through the gear 271, thereby achieving the winding of the waste tape 24. When the fixing block 25 disengages from the tape 24, the toothed block 256 separates from the rack 272.

[0033] Reference Figure 2 The ventilation box 2 includes a base 28 and a top cover 29. The top cover 29 is detachably connected to the base 28. A receiving cavity 281 is formed on the surface of the base 28 near the top cover 29, and components such as the tape 24 are located in the receiving cavity 281. The operator can remove the top cover 29 to replace the tape 24 in the receiving cavity 281. The separation of the top cover 29 and the base 28 facilitates the process of replacing the tape 24.

[0034] Reference Figure 2 The ventilation box 2 has an installation slot 241 for placing the tape 24, and a groove 242 is formed on the wall of the installation slot. A positioning spring 243 is fixedly connected to the bottom wall of the groove 242, and a fixed shaft 244 for rotating the tape 24 is fixedly connected to the end face of the positioning spring 243 away from the bottom wall of the groove 242. An operating block 245 is fixedly connected to the fixed shaft 244 extending out of the outer surface of the tape 24. The operating block 245 is used to facilitate the operator to move the fixed shaft 244 in the direction of compressing the positioning spring 243, so that the fixed shaft 244 can be removed from the installation slot 241, and the operator can replace the roll of tape 24.

[0035] The implementation principle of the intelligent and environmentally friendly primary and secondary integrated ring main unit in this application embodiment is as follows: When a high-speed train passes around the ring main unit in a high-dust environment, a strong wind is generated. The dust in the strong wind adheres to the tape 24. The filtered airflow then enters the housing 1 through the duct 22. The strong wind pushes the fixing block 25 onto the tape 24. Through the attraction of the first magnet 252 and the repulsion of the second magnet 253, the fixing block 25 moves the tape 24 closer to the first magnet 252, thereby replacing the tape 24 and fixing it. The toothed block 256 on block 25 drives the gear 271 to rotate via the rack 272, so that the rotating shaft 27 can wind up the waste tape 24. At the same time, the fixed block 25 passes through the guide slope 261 on the guide block 26 to separate the fixed block 25 and the tape 24. When the strong wind weakens, the fixed block 25 moves away from the tape 24 under the force of the drive spring 233, so that the fixed block 25 is located between the third magnet 254 and the fourth magnet 255. Under the repulsion of the third magnet 254 and the attraction of the fourth magnet 255, the fixed block 25 is reset.
