Description

Technical Field

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

[0002] In power distribution systems, integrated primary and secondary ring main units (RMUs) are key equipment widely used in outdoor environments, undertaking important tasks of power distribution and control. Their operational stability directly affects the reliability of regional power supply. However, outdoor RMUs are exposed to the natural environment for extended periods, facing challenges from various environmental factors, with rainwater having a particularly significant impact. Traditional RMUs lack effective resource utilization methods when dealing with rainwater, leading not only to water waste but also potential damage to the equipment due to rainwater accumulation. Therefore, developing outdoor RMUs with rainwater harvesting and utilization capabilities has become an important research direction for improving the environmental adaptability and resource utilization efficiency of equipment.

[0003] Currently, an outdoor ring network box with rainwater harvesting and reuse functions has emerged. This ring network box consists of a box body and a door installed on it. The bottom of the box body is fixed to a concrete base formed on the ground with screws. The top of the box body has an upward-curving water collection eave. A water collection chamber is pre-formed inside the base, and a water intake pipe connected to the water collection chamber is installed externally. Simultaneously, a water collection pipe is installed externally, connecting the bottom of the water collection eave to the water collection chamber. On rainy days, the water collection eave collects rainwater, which flows into the water collection chamber through the water collection pipe. When the water in the collection chamber needs to be reused, simply connect the external water pumping pipe to the water intake pipe, achieving a certain degree of rainwater recycling.

[0004] While the aforementioned ring network box structure effectively recycles rainwater, the rainwater flows directly into the collection chamber without any filtration or purification, potentially containing debris such as leaves, insects, or other solid particles. These impurities occupy the collection chamber's effective volume, reducing the usable water volume. When this rainwater is reused, it may clog contacting equipment, affecting its normal operation and even shortening its lifespan, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a primary and secondary integrated ring network box, which solves the problem that although rainwater can be recycled and reused through the water collection chamber in the above-mentioned related technologies, it may block the corresponding external pipes during later use, and there is room for improvement.

[0006] The technical solution for a primary and secondary integrated ring network box provided in this application is as follows:

[0007] A primary and secondary integrated ring network box includes a box body and a door installed on the front side of the box body. Several heat dissipation vents are provided on the vertical surfaces of the left and right sides of the box body. A base is fixed to the bottom of the box body, and a downward-sloping rain guide is installed on the top. An upward-opening rain collection trough is provided on the outer periphery of the rain guide. A water collection chamber for rainwater injection is provided inside the base, and a connector communicating with the water collection chamber is installed on the outside. Filter boxes located on the left and right sides of the box body are installed on the upper side of the base. A guide is provided outside the box body to inject rainwater from the rain collection trough into the water collection chamber. A connecting pipe connecting the filter boxes and the water collection chamber is provided outside the box body. A cleaning port is provided on the upper side of the filter box, and a cover plate for sealing the cleaning port can be detachably installed. A filter screen is fixed to the end face of the connecting pipe inserted into the filter box.

[0008] By adopting the above technical solution, the filter box uses a filter screen installed on the end face of the connecting pipe to perform preliminary filtration of rainwater, effectively intercepting solid particulate impurities such as broken leaves and insects. This prevents impurities from directly entering the water collection chamber inside the base, thus preventing the effective volume of the water collection chamber from being occupied, ensuring the available water volume, and reducing the risk of clogging external pipes and related equipment when using rainwater later, thereby extending the service life of the equipment. In addition, a cleaning port is opened on the upper side of the filter box, and a cover plate can be removed and installed to facilitate the regular cleaning of impurities trapped inside the filter box, ensuring the filtration effect and the long-term stable operation of the rainwater harvesting system, significantly improving the reliability and practicality of the ring network box in rainwater recycling.

[0009] Optionally, the flow guiding component includes a flow guiding hose and a flow guiding box located above the filter box. The flow guiding box has an inspection port and an inspection cover for sealing the inspection port. Two elastic rods are fixedly installed vertically on the base, with their upper ends fixedly connected to the bottom surface of the flow guiding box, and driving the flow guiding box to move upward. The two ends of the flow guiding hose are respectively connected to the bottom of the rainwater collection trough and the upper part of the flow guiding box. When the flow guiding box is full, it moves downward to the flow guiding state and upward to the accumulation state when it is not full. A flow guiding port is opened on the bottom surface of the flow guiding box, and an inspection cover is fixed on the inner wall. A protective cover is provided to protect the flow guide port. Several first through holes are opened on the outer periphery of the protective cover. The inside of the protective cover is provided with steel balls with a diameter larger than the flow guide port, which can block the flow guide port. A guide tube communicating with its own interior is fixed on the top surface of the filter box. A second through hole is opened on the outer periphery of the guide tube. When the flow guide box is in the flow guiding state, the guide tube passes through the flow guide port and is inserted into the protective cover, so that the steel balls are released from the blockage. The box body is provided with a locking device for locking and unlocking the flow guide box in the downward state.

[0010] By adopting the above technical solution, the elastic rod allows the guide box to move up and down, switching between accumulation and diversion states. When not full, it accumulates rainwater; when full, it automatically moves downwards to divert the water, improving the efficiency and rationality of rainwater collection. The design of the protective cover and steel balls seals the diversion opening when the guide box is not diverting water, preventing foreign objects from entering; when diverting water, the seal automatically releases, ensuring rainwater flows smoothly into the filter box. The second through hole on the guide pipe allows for better rainwater reception after the protective cover is inserted. The locking mechanism allows for locking and unlocking of the guide box in its downward movement, enhancing the stability and controllability of the device.

[0011] Optionally, two fixing rods are fixed on the side of the flow guide box facing the box body, and a guide through hole is opened on the box body in the vertical direction for the fixing rods to pass through and slide up and down. The opening of the guide through hole is blocked during the up and down sliding of the flow guide box.

[0012] By adopting the above technical solution, the cooperation between the fixing rod and the guide hole provides precise guidance for the up-and-down sliding of the diversion box, ensuring its stable position during movement and preventing deviation, thus guaranteeing the smoothness of the diversion process. Simultaneously, the diversion box maintains a sealed guide hole opening throughout its up-and-down sliding process, effectively preventing external debris and rainwater from entering the box through the guide hole, avoiding damage to the electrical equipment inside the box, improving the protective performance of the ring network box, and further enhancing the stability and reliability of the entire rainwater harvesting system.

[0013] Optionally, an upward-facing flow guide shroud is fixed to the inner edge of the heat dissipation vent, and a sealing plate is slidably mounted above the flow guide shroud. The box body is provided with a linkage connecting the sealing plate and the inner end of the fixing rod. When the flow guide box is in the flow guiding state, the sealing plate is moved down by the linkage to seal the flow guide shroud.

[0014] By adopting the above technical solution, the sliding sealing plate, in conjunction with the linkage and connecting parts, can move the sealing plate downwards to seal the diversion hood when the diversion box is in the diversion state, providing double protection against rainwater intrusion. In the non-diversion state, the sealing plate can be moved away to ensure normal ventilation and heat dissipation of the heat dissipation vents. This design, which automatically switches between protection and heat dissipation modes according to the state of the diversion box, takes into account both the waterproofing and heat dissipation requirements of the ring main unit, improving the stability and reliability of the equipment operation.

[0015] Optionally, the linkage includes two vertical rods that slide vertically on the inner wall of the box, and the two opposite sides of the sealing plate are fixedly connected to the sides of the two vertical rods that are close to each other; the lower ends of the two vertical rods are respectively connected and fixed to the inner ends of the fixing rod.

[0016] By adopting the above technical solution, when the state of the flow guide box changes and causes the fixed rod to move, the vertical rod and the sealing plate can be driven to move synchronously. This design does not require additional complex drive devices, has a simple structure, and is reliable in operation. By utilizing the linkage of the mechanical structure, the flow guide state of the flow guide box and the sealing state of the heat dissipation vent are automatically correlated. While ensuring the normal operation of the rainwater recovery function of the ring network box, it effectively prevents rainwater from entering the box through the heat dissipation vent, providing reliable protection for the electrical equipment inside the box and improving the practicality and stability of the entire device.

[0017] Optionally, a support rod is fixed to the inner wall of the housing, and the locking component includes a locking plate fixed between two vertical rods, an electromagnetic lock fixed to the support rod, and a sensor on the electromagnetic lock; the latch on the electromagnetic lock is located on the side facing the locking plate, and a locking slot is provided on the locking plate; when the flow guide box is in the flow guiding state, the locking plate moves down with the vertical rod, and the latch on the electromagnetic lock can be inserted into the locking slot at this time.

[0018] By adopting the above technical solution, when the diversion box is in the diversion state and drives the locking plate downward, the electromagnetic lock's bolt can accurately insert into the locking slot with the help of sensor sensing, achieving reliable locking of the diversion box in its downward state, preventing it from moving upward due to unexpected factors, and ensuring the stable operation of the diversion process. This electromagnetic lock locking method is precise in operation and responds quickly, making it more intelligent than traditional mechanical locking. Moreover, through the linkage between the sensor and the electromagnetic lock, locking and unlocking can be automatically controlled according to the actual state of the diversion box, improving the automation level and operational reliability of the entire device, effectively ensuring the stable and orderly operation of the diversion link in the ring network box rainwater recycling system, and providing strong support for the long-term stable operation of the equipment.

[0019] Optionally, the housing is provided with a limiting block, the limiting block having a limiting notch for a vertical rod to pass through and slide up and down, and the inner wall of the housing having a first slot for the limiting block to be inserted.

[0020] By adopting the above technical solution, a limiting notch is opened on the limiting block, which allows the vertical rod to slide up and down in it, providing precise guidance and limiting for the movement of the vertical rod, ensuring that the vertical rod can only move stably in the vertical direction without deviation or shaking, thereby ensuring the accuracy of the movement of components such as the sealing plate connected to the vertical rod.

[0021] Optionally, the two sides of the sealing plate are rotatably connected to the two vertical rods, the lower end of the vertical rods is rotatably connected to the inner end of the fixing rod, and a second slot is provided on the inner wall of the box; the vertical rod can rotate downward to a horizontal state when the limiting block is dislodged from the first slot, the limiting block can then be inserted into the second slot and support the bottom surface of the vertical rod in a horizontal state, and the sealing plate can then rotate to a state parallel to the top surface of the vertical rod.

[0022] By adopting the above technical solution, when the limiting block disengages from the first slot, the vertical rod can rotate downwards to a horizontal position. The limiting block, when inserted into the second slot, provides stable support, keeping the vertical rod horizontal. Simultaneously, the sealing plate can rotate to be parallel to the top surface of the vertical rod. This design allows for flexible adjustment of components during special circumstances such as maintenance, reducing space occupation, facilitating personnel operation, and not affecting normal functionality. It enhances the flexibility and practicality of the ring main unit structure, and facilitates maintenance and handling of the internal components.

[0023] Optionally, limiting slide bars are fixed on the opposite two side edges of the cover plate, and limiting slide grooves are provided on the opposite two inner edges of the cleaning port for the limiting slide bars to be inserted and slide back and forth.

[0024] By adopting the above technical solution, this structure can effectively limit the cover plate, prevent the cover plate from shaking or falling off after installation, ensure that it can tightly seal the cleaning port, effectively block external debris from entering the filter box, ensure the cleanliness of the filtration environment inside the filter box, and thus improve the stability and reliability of the entire ring network box rainwater recycling system.

[0025] Optionally, a traction handle is fixed on the upper side of the cover plate.

[0026] By adopting the above technical solution, when it is necessary to open or close the cover to clean or maintain the filter box, the operator can easily apply pulling or pushing force by holding the traction handle, so that the cover can slide smoothly along the limiting slide groove to complete the opening and closing action, which greatly improves the convenience and efficiency of operation.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] The filter box uses a filter screen installed on the end face of the connecting pipe to perform preliminary filtration of rainwater, effectively intercepting solid particulate impurities such as broken leaves and insects, preventing impurities from directly entering the water collection chamber in the base, thus preventing the effective volume of the water collection chamber from being occupied, ensuring the amount of usable water, and reducing the risk of clogging external pipes and related equipment when using rainwater later, thereby extending the service life of the equipment.

[0039] The present application will be further described in detail below with reference to all the accompanying drawings.

[0040] Example:

[0041] Reference Figure 1 and Figure 2 A primary and secondary integrated ring grate box includes a box body 1, a box door 2 installed on the front side of the box body 1, a base platform 3 fixed at the bottom of the box body 1, and a downwardly inclined rain guide eaves 12 installed at the top. The rain guide eaves 12 have an upwardly opening rain collection trough 13 on the outer periphery. The base platform 3 has a water collection cavity 31 for rainwater injection, and a connector 32 connected to the water collection cavity 31 is installed on the outside.

[0042] The upper side of the base 3 is equipped with filter boxes 4 located on the left and right sides of the box body 1. The box body 1 is provided with a guide 5 to inject rainwater in the rain collection trough 13 into the water collection cavity 31. The box body 1 is provided with a connecting pipe 41 connecting the filter box 4 and the water collection cavity 31. A filter screen 42 is fixed on the end face of the connecting pipe 41 inserted into the filter box 4.

[0043] When it rains outdoors, the rainwater is initially collected by the rainwater collection trough 13, and then the rainwater is directed into the filter box 4 by the guide 5. After filtration, the rainwater in the filter box 4 is finally directed into the water collection chamber 31 through the connecting pipe 41, thereby reducing the content of impurities in the collected rainwater.

[0044] Reference Figure 3 and Figure 4 The flow guide 5 includes a flow guide hose 51 and a flow guide box 52 located above the filter box 4. The two ends of the flow guide hose 51 are connected to the bottom of the rain collection trough 13 and the upper part of the flow guide box 52, respectively. Two elastic rods 53 are fixedly provided on the upper side of the base 3 along the vertical direction. The upper end face is fixedly connected to the bottom surface of the flow guide box 52, which drives the flow guide box 52 to move upward. The elastic rods 53 are a combination structure of conventional telescopic rod and spring, which will not be described in detail here.

[0045] When the flow guide box 52 is full of rainwater, the flow guide box 52 overcomes the upward elastic support force of the elastic rod 53 by its own weight, and moves itself to the flow guiding state. At this time, the rainwater in the flow guide box 52 can flow into the filter box 4. When the flow guide box 52 is not full, the elastic support force of the elastic rod 53 drives the flow guide box 52 to move upward to the accumulation state. At this time, the rainwater in the flow guide box 52 cannot flow into the filter box 4.

[0046] Reference Figure 5 The bottom surface of the flow guide box 52 is provided with a flow guide port 521, and a protective cover 54 is fixed on the inner wall to protect the flow guide port 521. Several first through holes are provided on the outer periphery of the protective cover 54, and steel balls 55 with a diameter larger than the flow guide port 521 are provided inside the protective cover 54 to block the flow guide port 521.

[0047] A guide pipe 43 connected to its interior is fixed on the top surface of the filter box 4, and a second through hole is opened on the outer periphery of the guide pipe 43. When the guide box 52 is in the flow guiding state, the guide box 52 moves down, so that the guide pipe 43 passes through the flow guiding port 521 and is inserted into the protective cover 54, so that the steel ball 55 releases the blockage of the flow guiding port 521.

[0048] Reference Figure 5 The flow box 52 has an inspection port 522 and a detachable inspection cover 523. One side of the inspection cover 523 is rotatably connected to the edge of the inspection port 522, and the other side of the inspection cover 523 can be detachably fixed to the flow box 52 to seal the inspection port 522 by conventional bolts.

[0049] The filter box 4 has a cleaning port 45 on its upper side and a cover plate 44 that can be detachably installed to block the cleaning port 45. The cover plate 44 has a limiting slide strip 441 fixed on the opposite two side edges, and the cleaning port 45 has a limiting slide groove 451 on the opposite two inner edges for the limiting slide strip 441 to be inserted and slide back and forth. The cover plate 44 has a traction handle 442 fixed on its upper side. When cleaning the inside of the filter box 4, the operator can pull the traction handle 442 to quickly open the cover plate 44, thereby improving the cleaning efficiency.

[0050] Reference Figure 6 Two fixing rods 56 are fixed on the side of the flow guide box 52 facing the box body 1. A guide hole 14 is opened on the box body 1 along the vertical direction for the fixing rods 56 to pass through and slide up and down. The opening of the guide hole 14 is blocked during the up and down sliding of the flow guide box 52. The stability of the flow guide box 52 when sliding up and down is improved by the sliding cooperation between the fixing rods 56 and the guide hole 14.

[0051] Reference Figure 6 and Figure 7 The box body 1 has several heat dissipation vents 11 on its left and right vertical surfaces. A diversion hood 15 with the opening facing upward is fixed on the inner edge of the opening of the heat dissipation vent 11. The box body 1 is provided with a sealing assembly 6 for sealing the upper opening of the diversion hood 15. The sealing assembly 6 includes a sealing plate 61 that slides above the diversion hood 15. The box body 1 is provided with a linkage 62 that connects the sealing plate 61 and the inner end of the fixing rod 56. The linkage 62 includes two vertical rods 621 that slide vertically on the inner wall of the box body 1. The two opposite sides of the sealing plate 61 are fixedly connected to the sides of the two vertical rods 621 that are close to each other.

[0052] The lower ends of the two vertical rods 621 are respectively connected and fixed to the inner ends of the fixed rod 56. When in the flow guiding state, the flow guiding box 52 drives the vertical rods 621 and the sealing plate 61 to move downward synchronously through the fixed rod 56, thereby causing the sealing plate 61 to move down and block the upper opening of the flow guide hood 15, reducing the possibility of external rainwater entering the box 1 from the heat dissipation port 11 at this time.

[0053] Reference Figure 7 The housing 1 is equipped with a locking element 57 for locking and unlocking the flow guide box 52 in the downward state. When the flow guide box 52 is in the downward state, the locking element 57 fixes the flow guide box 52 for a certain period of time (such as 30 seconds, 45 seconds, etc.) so that the rainwater in the flow guide box 52 can completely flow into the filter box 4. After a certain period of time, the locking element 57 releases the lock on the state of the flow guide box 52, and the flow guide box 52 moves upward and resets under the action of the elastic rod 53.

[0054] Reference Figure 6 and Figure 7A support rod 16 is fixed on the inner wall of the housing 1. The locking component 57 includes a locking plate 573 fixed between two vertical rods 621, an electromagnetic lock 571 fixed on the support rod 16, and a sensor 572 on the electromagnetic lock 571. The latch on the electromagnetic lock 571 is located on the side facing the locking plate 573. A locking slot 5731 is provided on the locking plate 573.

[0055] Specifically, the sensor 572 can be a "proximity switch". When an object approaches the sensing surface of the switch to the action distance, the switch can be activated without mechanical contact or the application of any pressure, thereby driving the electromagnetic lock 571 to provide control commands. This is a conventional structure and will not be described in detail here.

[0056] The staff pre-programs the electromagnetic lock 571. When the sensor 572 senses the locking plate 573 moving down (that is, when the flow guide box 52 is in the flow guide state), the electromagnetic lock 571 is activated to insert, so that the locking tongue on the electromagnetic lock 571 is inserted into the locking slot 5731 for a certain period of time (such as 30 seconds, 45 seconds, etc.). Then the electromagnetic lock 571 releases the lock on the flow guide box 52.

[0057] Reference Figure 8 The housing 1 is provided with a limiting block 622, wherein the limiting block 622 has a limiting notch for the vertical rod 621 to pass through and slide up and down, and the inner wall of the housing 1 has a first slot 17 for the limiting block 622 to be inserted; so as to facilitate the installation and fixing of the limiting block 622.

[0058] Reference Figure 8 and Figure 9 The two sides of the sealing plate 61 are rotatably connected to the two vertical rods 621 by wing bolts. The rotation state of the sealing plate 61 is controlled by tightening or loosening the wing bolts. This is a conventional structure and will not be described in detail here. The lower end of the vertical rod 621 is rotatably connected to the inner end of the fixing rod 56. A second slot 18 is provided on the inner wall of the box 1.

[0059] When repairing electrical equipment inside the ring main unit, first pull out the limiting block 622 from the first slot 17 and insert it into the second slot 18. Then, rotate the vertical rod 621 downwards to a horizontal position. At this time, the limiting block 622 supports the bottom surface of the vertical rod 621 in a horizontal position. Then, rotate the sealing plate 61 to a position parallel to the top surface of the vertical rod 621. The vertical rod 621 and the sealing plate 61 form a platform for placing repair tools. At this time, the upper side of the electromagnetic lock 571 abuts against the bottom surface of the locking plate 573, thereby using the electromagnetic lock 571 to further support the platform.

[0060] The implementation principle of this application embodiment is as follows:

[0061] On rainy days outdoors, when the flow box 52 is full of rainwater, it moves down to the flow guiding state by overcoming the upward elastic support force of the elastic rod 53 under its own weight. At this time, the flow box 52 moves down so that the guide pipe 43 passes through the flow port 521 and is inserted into the protective cover 54, which releases the blockage of the flow port 521 by the steel ball 55. The rainwater is injected into the filter box 4, filtered by the filter screen 42, and then flows into the water collection chamber 31 through the connecting pipe 41.

[0062] When the flow guide box 52 is in the flow guiding state, the vertical rod 621 and the sealing plate 61 move down synchronously through the fixing rod 56. The sealing plate 61 seals the upper opening of the flow guide cover 15, reducing the amount of rainwater entering the box 1 from the heat dissipation port 11. At the same time, the sensor 572 senses the downward movement of the locking plate 573, the electromagnetic lock 571 is activated, and the locking tongue is inserted into the locking slot 5731 to lock the flow guide box 52 for a certain period of time. After the rainwater has completely flowed into the filter box 4, it is unlocked, and the flow guide box 52 moves up and resets under the action of the elastic rod 53.

[0063] When repairing electrical equipment inside the ring main unit, the limiting block 622 is pulled out from the first slot 17 and inserted into the second slot 18, causing the vertical rod 621 to rotate downwards to a horizontal state. The limiting block 622 supports the vertical rod 621. Then, the sealing plate 61 is rotated to be parallel to the top surface of the vertical rod 621. The vertical rod 621 and the sealing plate 61 form a platform for placing repair tools, and the upper side of the electromagnetic lock 571 abuts against the bottom surface of the locking plate 573 to further support the platform.

[0064] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
