Description

Technical Field

[0001] This invention belongs to the field of ring main units, specifically a high-reliability ring main unit. Background Technology

[0002] A ring main unit (RMU) is an electrical device that houses a group of power transmission and distribution equipment (high-voltage switches) within a metal or non-metal insulated cabinet or is configured as a modular ring network power supply unit. Its core components utilize load switches and fuses. It offers advantages such as simple structure, small size, low cost, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] During the use of ring main units, extreme humidity conditions may occur, such as rain or heavy fog. In these conditions, the air humidity is very high, which can easily lead to a large amount of moisture entering the ring main unit and corroding the equipment inside. The large amount of moisture causes the equipment to be soaked in liquid and solid particles (mainly H2O), which can easily lead to short circuits, corrosion and other problems for the electrical components (including load switches and fuses), making them unable to operate normally. Therefore, a high-reliability ring main unit is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: During the use of ring main units, extreme humid conditions may be encountered, such as rain or heavy fog. At this time, the air humidity is very high, which can easily cause a large amount of moisture to enter the ring main unit, thereby threatening the equipment inside the ring main unit. The large amount of moisture causes the equipment to be soaked in liquid (mainly H2O), which can easily lead to problems such as short circuits and corrosion, and prevent the equipment from operating normally.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a high-reliability ring network box, comprising: an outer box assembly, the outer box assembly including an outer box, a receiving cavity, a communication channel 1 and a flow channel, the receiving cavity being provided on the inner side of the outer box, a plurality of communication channels 1 being recessed on one side of the inner side of the receiving cavity, a plurality of flow channels 1 being recessed on the inner bottom wall of the communication channel 1, the flow channels intersecting with the horizontal plane;

[0007] An air outlet assembly includes an intermediate cavity, an air outlet channel one, and an air outlet channel two. The intermediate cavity is recessed on the other side of the outer casing. Several air outlet channels two are recessed on one side of the intermediate cavity, and several air outlet channels one are recessed on the other side of the intermediate cavity. Both air outlet channels one and air outlet channels two intersect with the horizontal plane.

[0008] A ventilation assembly, which is installed inside the communication channel one;

[0009] A rain cover assembly, which is located on top of the outer casing.

[0010] As a preferred technical solution for a high-reliability ring network box, the rainproof cover assembly includes an outer cover, a mounting cavity, and an absorbent cloth. The outer cover has sloping sides, and a mounting cavity is reserved on the sloping sides. An absorbent cloth is installed in the mounting cavity.

[0011] When it rains, the rain is drained through the slope of the outer cover, and some of the rain soaks into the absorbent cloth to keep the outer wall of the cover moist. This allows the temperature of the rain cover assembly and the outer casing assembly to be reduced by absorbing heat through the evaporation of the liquid.

[0012] As a preferred technical solution for a high-reliability ring network box, a liquid storage component is installed on the rainproof cover assembly. The liquid storage component includes a liquid storage chamber, a liquid collection groove, and a connecting groove. A liquid storage chamber is formed between the outer box and the liquid storage chamber. A liquid collection groove is recessed at the top of the liquid storage chamber. A connecting groove is reserved between the liquid collection groove and the liquid storage chamber. A second communication channel connects the liquid storage chamber and the mounting chamber.

[0013] Some raindrops enter the storage chamber through the liquid collection channel and the connecting channel and are stored there. The liquid in the storage chamber is supplied to the liquid-absorbing cloth through the second communication channel. The temperature of the rain cover assembly and the outer box assembly can be reduced by absorbing heat through the evaporation of the liquid.

[0014] The moisture mainly refers to small droplets.

[0015] As a preferred technical solution for a high-reliability ring main unit, the ventilation assembly includes a gasket, a first sieve plate, a square cylinder, a second absorbent cloth, a pressure table, the second sieve plate, a base frame, a moving seat, a guide groove, and a ventilation fan. The square cylinder is arranged on the upper side of the gasket, and the base frame and ventilation fan are located inside the square cylinder. The second absorbent cloth is located on the upper side of the base frame. The guide groove is recessed at the bottom of the inner side of the square cylinder. There are two moving seats, and each moving seat is connected to a folding frame. The folding frame is connected to the base frame.

[0016] An elastic element two is connected between the two motion seats, and the elastic element two can maintain the distance between the two motion seats;

[0017] When the two motion seats move away from each other, the second elastic element will be stretched. In order to maintain its original shape, the second elastic element will prevent the two from moving away. The second elastic element can bring the two motion seats back together to the original spacing size.

[0018] As a preferred technical solution for high-reliability ring main units, the ventilation assembly also includes:

[0019] The offset assembly includes a movable frame located inside the square tube, a steel platform fixedly connected to the movable frame, and a magnet mounted on the moving base;

[0020] The rotating assembly includes a rotating shaft, and the number of the pressing platforms is 2. All the pressing platforms are connected to the movable frame. Several abutment platforms are installed on the wall of the pressing platform facing the absorbent cloth 2. The abutment platforms are hemispherical.

[0021] As a preferred technical solution for a high-reliability ring network box, during the compression of the volume of the absorbent cloth II by the compression table, the contact table will directly press the outer circumference of the absorbent cloth II before the compression table, so that the absorbent cloth II is compressed and the liquid inside is discharged. As the compression table continues to press the absorbent cloth II, the area of ​​the absorbent cloth II under pressure gradually increases, thereby avoiding excessive impact when the compression table and the absorbent cloth II first come into contact, which would cause the liquid to spray violently.

[0022] As a preferred technical solution for a high-reliability ring network box, the two ends of the rotating shaft one are respectively screwed to the moving frame and the rotating frame, the rotating frame is pinned to the swing arm, all the pressing tables are connected to the rotating shaft two, the pressing table and the rotating shaft two are screwed together, and the rotating shaft two is connected to the pressing table by a torsion spring.

[0023] The pressing table is rotated around the pivot shaft. During the rotation of the pressing table, the torsion spring will accumulate mechanical energy and drive the pressing table back to its original position. The rotating assembly also includes a vertical frame, which is placed inside the square tube. One end of the swing arm is pinned to the vertical frame.

[0024] Because the two ends of the swing arm are pinned to the vertical frame and the rotating frame respectively, the swing arm swings and folds when the distance between the rotating frame and the vertical frame decreases. The inner bottom wall of the square tube has a reserved movable cavity, and the movable frame is variably connected to the movable cavity.

[0025] The movable frame is connected to the movable cavity using an elastic element. Since the two ends of the elastic element are fixedly connected to the movable cavity and the movable frame respectively, the movable frame is driven when the attraction of the magnet on the movable frame on the moving seat is greater than the resistance of the static friction force on the elastic element and the movable frame.

[0026] As a preferred technical solution for a high-reliability ring main unit, the drive assembly includes a shaft 1, which is screwed onto a screen plate 2. The screen plate 2 is movably connected to a square cylinder. A cleaning frame is installed at one end of the shaft 1. A side seat is arranged on the upper side of the gasket. The side seat is screwed onto the shaft 2. Three or more linkage frames are equally spaced on the wall of one end of the shaft 2. Three or more mating holes are recessed at the end of the shaft 1 facing the linkage frames. The mating holes and linkage frames are movably inserted into each other.

[0027] Because a stepper motor is installed on the side seat, the rotating column of the stepper motor is connected to the second coaxial shaft. The stepper motor uses the second shaft to drive the first shaft to rotate. A channel is reserved in the middle of the first screen plate. An elastic element four is also connected between the second screen plate and the square cylinder.

[0028] As a preferred technical solution for a high-reliability ring mesh box, during the process of the compression table and the second sieve plate working together to compress the volume of the second absorbent cloth, the elastic element four on the second sieve plate buffers the movement of the second sieve plate and the compression table, preventing the liquid from splashing at high speed due to the second absorbent cloth being compressed too quickly.

[0029] The liquid is mainly H2O, and the steel platform and the absorbent cloth are made of cotton.

[0030] The guide channel and the flow channel correspond and connect.

[0031] The beneficial effects of a high-reliability ring main unit of the present invention are as follows: By using the ventilation component and the air outlet component, outside air passes through the square cylinder. During this process, the air passes through the first screen plate, the second absorbent cloth, and the second screen plate in turn, and finally enters the receiving cavity. Dust in the air is blocked by the first screen plate, and moisture in the air is removed by the second absorbent cloth, thus preventing moisture in the air from affecting the normal operation of the equipment in the receiving cavity. The hot air in the receiving cavity is pushed out through the second air outlet channel, the first air outlet channel, and the intermediate cavity, thereby cooling the equipment in the receiving cavity.

[0032] By using the compression table, the outer circumference of the absorbent cloth is compressed, causing the liquid inside to be expelled. As the compression table continues to compress the absorbent cloth, the area of ​​the absorbent cloth in direct contact with the compression table gradually increases, thus avoiding excessive impact when the compression table first contacts the absorbent cloth, which would cause the liquid to spray violently. This allows the liquid to be expelled more thoroughly while preventing it from splashing into the receiving cavity. The expelled liquid reaches the guide groove and then the flow channel, where it is discharged, restoring the absorbent cloth's moisture absorption capacity. Attached Figure Description

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0044] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0045] like Figure 1-6 As shown, the present invention proposes a high-reliability ring main unit, comprising: an outer casing assembly 100, the outer casing assembly 100 including an outer casing 101, a receiving cavity 102, a communication channel 103, and a flow channel 104. The receiving cavity 102 is provided on the inner side of the outer casing 101, and several communication channels 103 are recessed on one side of the inner side of the receiving cavity 102. Several flow channels 104 are recessed on the inner bottom wall of the communication channel 103, and the flow channels 104 intersect with the horizontal plane.

[0046] The air outlet assembly 200 includes an intermediate cavity 201, an air outlet channel 1 202, and an air outlet channel 203. The intermediate cavity 201 is recessed on the other side of the outer casing 101. Several air outlet channels 203 are recessed on one side of the intermediate cavity 201, and several air outlet channels 1 202 are recessed on the other side of the intermediate cavity 201. Both the air outlet channels 1 202 and the air outlet channels 203 intersect with the horizontal plane.

[0047] Ventilation assembly 500, wherein the ventilation assembly 500 is installed inside the communication channel 103;

[0048] Rain cover assembly 300, which is located on top of outer casing 101.

[0049] The rainproof cover assembly 300 includes an outer cover 301, a mounting cavity 302, and an absorbent cloth 303. The outer cover 301 has sloping sides, and the mounting cavity 302 is reserved on the sloping surface. The absorbent cloth 303 is installed in the mounting cavity 302.

[0050] When it rains, the rain is drained through the slope of the outer cover 301, and some of the rain soaks into the absorbent cloth 303 to keep the outer wall of the outer cover 301 moist. This allows the temperature of the rain cover assembly 300 and the outer casing assembly 100 to be reduced by absorbing heat through the evaporation of liquid.

[0051] The rainproof cover assembly 300 is equipped with a liquid storage assembly 400, which includes a liquid storage chamber 401, a liquid collection groove 402, and a connecting groove 403. The liquid storage chamber 401 is formed between the outer casing 101 and the liquid storage chamber 401. The liquid collection groove 402 is recessed at the top of the liquid storage chamber 401. A connecting groove 403 is reserved between the liquid collection groove 402 and the liquid storage chamber 401. A communication channel 404 connects the liquid storage chamber 401 and the mounting cavity 302.

[0052] Some raindrops enter the storage chamber 401 through the liquid collection channel 402 and the connecting channel 403 and are stored there. The liquid in the storage chamber 401 is supplied to the absorbent cloth 303 through the second communication channel 404. The temperature of the rain cover assembly 300 and the outer box assembly 100 can be reduced by absorbing heat through the evaporation of the liquid.

[0053] The moisture mainly refers to small droplets.

[0054] The ventilation assembly 500 includes a gasket 512, a first sieve 515, a square cylinder 516, a second absorbent cloth 520, a pressure table 522, a second sieve 524, a base frame 531, a motion seat 534, a guide groove 535, and a ventilation fan. The square cylinder 516 is arranged on the upper side of the gasket 512. The base frame 531 and the ventilation fan are both located inside the square cylinder 516. The second absorbent cloth 520 is located on the upper side of the base frame 531. The guide groove 535 is recessed into the bottom of the inner side of the square cylinder 516. There are two motion seats 534. Each motion seat 534 is connected to a folding frame 532. The folding frame 532 is connected to the base frame 531.

[0055] An elastic element 533 is connected between the two motion seats 534, and the elastic element 533 can maintain the distance between the two motion seats 534.

[0056] When the two motion seats 534 move away from each other, the elastic element 533 will be stretched. The elastic element 533 will prevent the two from moving away in order to maintain its original shape. The elastic element 533 can bring the two motion seats 534 back together to the original spacing size.

[0057] The ventilation assembly 500 also includes:

[0058] The offset assembly includes a movable frame 523 located inside the square tube 516, and a steel platform 530 fixedly connected to the movable frame 523. A magnet is mounted on the moving seat 534.

[0059] The rotating assembly includes a rotating shaft 526, and two pressing platforms 522. All pressing platforms 522 are connected to the moving frame 523. Several abutment platforms 521 are installed on the wall of the pressing platform 522 facing the absorbent cloth 520. The abutment platforms 521 are hemispherical.

[0060] During the compression of the absorbent cloth 520 by the compression table 522, the contact table 521 will directly press the outer circumference of the absorbent cloth 520 before the compression table 522, so that the absorbent cloth 520 is compressed and the liquid inside is discharged. As the compression table 522 continues to compress the absorbent cloth 520, the area of ​​the absorbent cloth 520 under compression gradually increases, thereby avoiding excessive impact when the compression table 522 and the absorbent cloth 520 first come into contact, which would cause the liquid to spray violently.

[0061] The two ends of the rotating shaft 526 are respectively screwed to the movable frame 523 and the rotating frame 529. The rotating frame 529 is pinned to the swing arm 527. All the pressing tables 522 are connected to the rotating shaft 536. The pressing table 522 and the rotating shaft 536 are screwed together. The rotating shaft 536 is connected to the pressing table 522 by a torsion spring 537.

[0062] The pressing table 522 is rotated around the rotating shaft 536. During the rotation of the pressing table 522, the torsion spring 537 will accumulate mechanical energy and drive the pressing table 522 back to its original position. The rotating assembly also includes a vertical frame 528, which is placed inside the square tube 516. One end of the swing arm 527 is pinned to the vertical frame 528.

[0063] Because the two ends of the swing arm 527 are pin-connected to the vertical frame 528 and the rotating frame 529 respectively, the swing arm 527 swings and folds when the distance between the rotating frame 529 and the vertical frame 528 decreases. The inner bottom wall of the square tube 516 has a reserved movable cavity, and the movable frame 523 is variably connected to the movable cavity.

[0064] The movable frame 523 is connected to the movable cavity via an elastic element 525. Since the two ends of the elastic element 525 are fixedly connected to the movable cavity and the movable frame 523 respectively, the movable frame 523 is driven when the attraction of the magnet on the movable frame 523 on the moving seat 534 is greater than the resistance of the static friction force on the elastic element 525 and the movable frame 523.

[0065] The drive assembly includes a shaft 514, which is screwed onto a screen plate 524. The screen plate 524 is movably connected to a square cylinder 516. A cleaning frame 517 is installed at one end of the shaft 514. A side seat 513 is arranged on the upper side of the gasket 512. The side seat 513 is screwed onto a shaft 518. Three or more linkage frames 519 are evenly spaced on the wall surface of one end of the shaft 518. Three or more mating holes are recessed at the end of the shaft 514 facing the linkage frame 519. The mating holes and the linkage frame 519 are movably inserted into each other.

[0066] Because the side seat 513 is equipped with a stepper motor 539, the rotating column of the stepper motor 539 is connected to the second coaxial 518. The stepper motor 539 uses the second coaxial 518 to drive the first coaxial 514 to rotate. The middle part of the first sieve plate 515 has a reserved channel. The second sieve plate 524 and the square cylinder 516 are also connected by an elastic element 4.

[0067] During the process of the compression table 522 and the second sieve plate 524 working together to compress the volume of the second absorbent cloth 520, the elastic element 4 on the second sieve plate 524 buffers the movement of the second sieve plate 524 and the compression table 522, preventing the liquid from splashing at high speed due to the rapid compression of the second absorbent cloth 520.

[0068] The liquid is mainly H2O, and the steel platform 530 and the absorbent cloth 303 are made of cotton.

[0069] The guide channel 535 and the flow channel 104 correspond and are connected.

[0070] The elastic element one, elastic element two, elastic element three and elastic element four are all made of elastic metal wire spirally wound; the guide groove 535 penetrates the gasket 512.

[0071] The specific implementation method is as follows: Because an exhaust fan is installed inside the square cylinder 516, when the exhaust fan is working, the outside air passes through the square cylinder 516, passes through the first screen plate 515, the second absorbent cloth 520 and the second screen plate 524, and finally enters the receiving cavity 102. The dust in the air is blocked by the first screen plate 515, and the moisture in the air is removed by the second absorbent cloth 520, so as to prevent the moisture in the air from affecting the normal operation of the equipment in the receiving cavity 102. After the outside air enters the receiving cavity 102 through the ventilation component 500, the hot air in the receiving cavity 102 is pushed out through the second air outlet channel 203, the first air outlet channel 202 and the intermediate cavity 201, so that the equipment in the receiving cavity 102 is cooled down.

[0072] After the absorbent cloth 520 absorbs moisture, its mass increases, causing the base frame 531 to descend, the folding frame 532 to swing, and then the folding frame 532 will push the distance between the two moving seats 534 to increase.

[0073] During this period, the magnet on the motion seat 534 will approach the steel platform 530, and the force exerted on the steel platform 530 by the magnetic field will increase until the steel platform 530 can pull the moving frame 523 to move. At this time, the force exerted on the steel platform 530 by the magnetic field just exceeds the sum of the maximum static friction force on the moving frame 523 and the force exerted by the elastic element 525. Because the dynamic friction force on the moving frame 523 is less than the maximum static friction force on the moving frame 523, the moving frame 523 can bring the pressing platform 522 close to the screen plate 524. Then the pressing platform 522 and the screen plate 524 cooperate to compress the volume of the absorbent cloth 520, and the liquid in the absorbent cloth 520 is then discharged.

[0074] In the first stage, when the rotating frame 529 is perpendicular to the horizontal plane, it is positioned between the two pressure platforms 522. During the offset of the moving frame 523, as the distance between the rotating frame 529 and the vertical frame 528 decreases, the swing arm 527 swings and folds, causing the rotating frame 529 to rotate as well. The rotating frame 529 rotates around the axis of the first rotating shaft 526, and each end of the rotating frame 529 abuts against a pressure platform 522, causing the two pressure platforms 522 to swing open. During the opening of the pressure platforms 522, the contact point between them and the second absorbent cloth 520 changes, allowing the pressure platforms 522 to press at different points on the second absorbent cloth 520, thereby subjecting the second absorbent cloth 520 to more thorough compression and increasing the proportion of liquid removed from the second absorbent cloth 520. During the compression of the volume of the absorbent cloth 520 by the compression table 522, the contact table 521 will directly press the outer peripheral surface of the absorbent cloth 520 before the compression table 522, so that the absorbent cloth 520 is compressed and the liquid is discharged. As the compression table 522 continues to compress the absorbent cloth 520, the area of ​​the absorbent cloth 520 directly contacting the compression table 522 and the area of ​​the absorbent cloth 520 being compressed will increase. This avoids excessive impact when the compression table 522 and the absorbent cloth 520 first come into contact, which would cause the liquid to spray violently. This allows the liquid to be discharged more thoroughly while preventing the liquid from splashing into the receiving cavity 102. The discharged liquid reaches the guide groove 535 and then reaches the flow channel 104, where it is discharged.

[0075] Because the second sieve plate 524 is dynamically connected inside the square cylinder 516, the elastic element 4 on the second sieve plate 524 buffers the movement of the second sieve plate 524 and the pressure table 522, preventing the liquid from splashing at high speed due to the rapid compression of the absorbent cloth 520. During this process, the second sieve plate 524 is buffered and shifts together with the first shaft 514, causing the first shaft 514 to come into contact with the second shaft 518. The connecting frame 519 and the mating groove in the first shaft 514 are connected and moved. Then, under the control of the stepper motor 539, the second shaft 518 rotates the cleaning frame 517 on the first shaft 514 through the first shaft 514. The cleaning filaments on the cleaning frame 517 are soft and tough. The cleaning frame 517 is always in frictional contact with the first sieve plate 515. During the rotation of the cleaning frame 517, the dust on the outside of the first sieve plate 515 can be swept away, restoring its normal filtration capacity and preventing the sieve holes from closing.

[0076] After the liquid inside the absorbent cloth 520 is expelled, the weight of the absorbent cloth 520 decreases, and the elastic element 533 releases mechanical energy to bring the moving seat 534 closer, which in turn causes the folding frame 532 to swing and push the base frame 531 and the absorbent cloth 520 upward. The magnet on the moving seat 534 also moves away from the steel platform 530. The force exerted by the magnet on the moving frame 523 by the steel platform 530 is less than the force exerted by the elastic element 525. The elastic element 525 can then move the moving frame 523 back to its previous location until the next time the absorbent cloth 520 absorbs moisture and becomes heavier, triggering a chain reaction.

[0077] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
