Description
Technical Field
[0001] This invention relates to the field of power distribution equipment technology, specifically to a primary and secondary integrated ring network box with waterproof and drainage functions. Background Technology
[0002] Integrated primary and secondary ring main units are core infrastructure equipment for smart distribution network construction. They deeply integrate primary high-voltage switchgear with secondary intelligent monitoring and control terminals, achieving multi-functional integration of protection, control, measurement, communication, and fault self-healing for distribution lines. They are widely used in outdoor power distribution locations such as urban core areas, residential communities, and industrial parks. Compared to traditional split-type ring main units, they achieve factory prefabrication and integrated commissioning, completely solving the problems of complex on-site wiring, long commissioning cycles, and poor compatibility of primary and secondary equipment associated with traditional equipment. This significantly shortens the construction cycle and reduces on-site construction risks. With the advancement of dual-carbon goals and the large-scale grid connection of distributed photovoltaics, energy storage, and other new energy sources, the operating characteristics of distribution networks are undergoing profound changes, placing higher demands on the intelligence level and rapid fault handling capabilities of distribution equipment. Integrated primary and secondary ring main units, with their powerful edge computing capabilities and standardized communication interfaces, can perfectly adapt to various new application scenarios. As the automation transformation of my country's distribution network continues to accelerate, the market demand for integrated primary and secondary ring main units continues to rise. Their long-term stable operation capability in complex outdoor environments is directly related to the power supply reliability of the entire distribution network.
[0003] To improve the waterproof and moisture-proof performance of outdoor ring main units, the industry currently uses a composite process of epoxy zinc-rich paint and polyurethane sealant to fully cover the bottom plate of the unit, attempting to solve the water ingress problem by completely isolating external moisture. However, this design approach, which relies excessively on "blocking," has a fundamental flaw: the sources of moisture inside the ring main unit are diverse. Leaks due to aging door seals, condensation from ventilation, rising moisture from cable trenches, and moisture introduced during installation and maintenance cannot be discharged through the fully sealed bottom plate and can only accumulate at the bottom of the unit. Long-term water accumulation will continuously soak the bottom electrical components, accelerating metal corrosion and insulation material aging, ultimately leading to serious accidents such as short circuits, tripping, and equipment burnout. Existing technologies either completely eliminate drainage or introduce normally open drainage holes, leading to backflow of moisture, thus failing to resolve the core contradiction between sealing and drainage. Summary of the Invention
[0004] The purpose of this invention is to provide a primary and secondary integrated ring network box with waterproof and drainage functions, so as to solve the fundamental defects of the existing fully sprayed sealed box bottom plate design mentioned in the background art, which relies too much on "blocking". Water from various sources inside cannot be discharged and accumulates at the bottom. Long-term water accumulation will corrode metal, age insulation and cause accidents such as short circuit tripping. Moreover, the existing technology cannot solve the problems of sealing and drainage at the same time.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a primary and secondary fusion ring mesh box with waterproof and drainage functions, comprising a sealed spraying box body, a box door rotatably installed on one side, and a main cabinet installed inside the sealed spraying box body. The sealed spraying box body has inclined grooves circumferentially formed on its bottom walls near the main cabinet body. A connecting frame is provided at the top of the inclined grooves. A drive adjustment assembly is provided inside the side of the sealed spraying box body near the connecting frame. Several drainage holes are circumferentially formed on the bottom wall of the inclined grooves. A liquid level sensor is fixed to the bottom wall of the inclined grooves. A drainage assembly is provided inside the inclined grooves corresponding to the position of each drainage hole. The drainage assembly includes a positioning rod and a sealing block. The positioning rod is fixed to the bottom wall of the inclined grooves, and the sealing block is slidably disposed inside the drainage hole. A waterproof component is provided inside the sealing block.
[0006] Furthermore, the drive adjustment assembly includes a stepper motor and a lead screw. A mounting bracket is fixedly installed on one side of the stepper motor and is fixed to the inner wall of the sealed spraying box. The lead screw passes through one side of the connecting bracket and is installed by threaded engagement. The top end of the lead screw is coaxially and fixedly connected to the output end of the stepper motor.
[0007] Furthermore, a rotating shaft is coaxially fixedly connected to the bottom end of the lead screw, and the bottom end of the rotating shaft is embedded and rotatably installed inside the bottom wall of the inclined groove. A positioning seat is sleeved and rotatably installed on the outside of the rotating shaft, and one end of the positioning seat is fixedly installed on the inner wall of the sealed spraying box.
[0008] Furthermore, auxiliary rods are vertically and slidably installed inside both sides of the connecting frame near the stepper motor. The bottom end of the auxiliary rod is embedded and fixed on the bottom wall of the inclined groove, and an auxiliary seat is fixedly installed on the top end of the auxiliary rod. One end of the auxiliary seat is fixedly installed on the inner wall of the sealed spraying box.
[0009] Furthermore, a slider is slidably mounted on the outer side of the positioning rod near its top end. A mounting block is fixed to one end of the slider. A limit rod is vertically fixed inside the mounting block. A stop block is fixed to the top of the positioning rod. A positioning bolt is threaded between the mounting block and the connecting frame.
[0010] Furthermore, a spray block of the same material as the bottom wall of the sealing spray box is fixed to the bottom end of the sealing block, a retaining ring is fixed to the top of the sealing block, a rubber ring is embedded in the bottom end of the retaining ring, and a first annular sealing groove is formed on the bottom wall of the inclined groove near the rubber ring.
[0011] Furthermore, a rotating rod is rotatably installed inside the bottom end of the sealed spraying box. An auxiliary handle is fixed to one end of the rotating rod near the box door, and a first bevel gear is fixed to the other end of the rotating rod. A second bevel gear is sleeved and fixed to the outside of the rotating shaft, and the first bevel gear and the second bevel gear are meshed and connected.
[0012] Furthermore, the waterproof component includes an air storage chamber and a piston block. The air storage chamber is located inside the sealing block. The piston block is slidably and sealingly installed inside the air storage chamber. The bottom end of the limiting rod penetrates the top wall of the sealing block and is slidably installed inside the air storage chamber. One end of the limiting rod located inside the air storage chamber is fixedly connected to the top end of the piston block.
[0013] Furthermore, a limiting spring is sleeved on the outside of the limiting rod, and the two ends of the limiting spring are respectively fixedly installed on the outside of the bottom end of the slider and the outside of the top end of the sealing block. An annular mounting groove is opened around the outside of the sealing block near the bottom of the gas storage cavity.
[0014] Furthermore, a sealing airbag is arranged around the inside of the annular mounting groove. Several air guide pipes are fixedly connected to the inside of the sealing airbag on the side near the air storage chamber. The end of each air guide pipe away from the sealing airbag passes through and is fixedly installed inside the bottom of the air storage chamber. A second annular sealing groove is formed around the inner wall of the drain hole near the bottom.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a sloping groove around the main cabinet on the bottom wall of the sealed spraying box, and cooperating with a sealing block that can be opened and closed synchronously, achieves automatic and reliable drainage of internal water while fully retaining the core advantage of the existing fully sprayed sealed bottom plate in isolating external moisture. Under normal conditions, the sealing block is inserted into the drain hole, and the outer surface of the sprayed block at its bottom end is treated with the same material sealing coating as the bottom wall of the sealed spraying box, ensuring the continuity of the bottom plate sealing layer. The rubber ring at the bottom end of the retaining ring is embedded in the first annular sealing groove to form an end face seal, solving the problem of moisture backflow in the existing normally open drain hole. When water accumulates, the liquid level sensor triggers the stepper motor to drive the lead screw to lift and lower the connecting frame, realizing the synchronous opening and closing of the drain hole. With the help of an independent auxiliary handle and a pure mechanical manual emergency structure with bevel gear transmission, reliable drainage can still be ensured under extreme conditions such as power failure and stepper motor failure, greatly improving the system's operational stability and power supply reliability.
[0016] 2. This invention integrates waterproof components inside the sealing block, forming a dual sealing system combining end-face sealing and radial soft sealing. This significantly improves sealing performance and service life. During sealing, the limiting rod drives the piston block to compress the gas in the gas storage chamber. The gas is then introduced through the air guide pipe, causing the sealing airbag to expand and embed into the second annular sealing groove, achieving adaptive sealing. The sealing effect is far superior to that of a single sealing structure. When opening, the piston block first moves upward to completely retract the sealing airbag into the annular mounting groove, and then drives the sealing block to lift as a whole. This avoids friction and wear between the sealing component and the inner wall of the drainage hole, solving the industry problem of existing sealing components aging and failing easily after long-term opening and closing. This ensures that the sealing life is relatively matched with the design life of the ring network box body, guaranteeing the overall waterproof effect. Attached Figure Description

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.
[0020] Example 1: Please refer to Figures 1-9 A primary and secondary integrated ring mesh box with waterproof and drainage functions includes a sealed spraying box body 1, a box door 2 rotatably installed on one side, and a main cabinet body 3 installed inside the sealed spraying box body 1. A sloping groove 4 is formed around the bottom wall of the sealed spraying box body 1 near the main cabinet body 3. A connecting frame 5 is provided at the top of the sloping groove 4. A drive adjustment component is provided inside the side of the sealed spraying box body 1 near the connecting frame 5. Several drainage holes 11 are formed around the bottom wall of the sloping groove 4. A liquid level sensor 36 is fixed to the bottom wall of the sloping groove 4, and the liquid level sensor 36 is fixedly installed at the lowest position of the sloping groove 4 to ensure timely detection of water accumulation. A drainage component is provided inside the sloping groove 4 corresponding to the position of each drainage hole 11. The drainage component includes a positioning rod 12 and a sealing block 15. The positioning rod 12 is fixed to the bottom wall of the sloping groove 4, and the sealing block 15 is slidably disposed inside the drainage hole 11.
[0021] The drive adjustment assembly includes a stepper motor 6 and a lead screw 7. A mounting bracket 33 is fixedly installed on one side of the stepper motor 6. The mounting bracket 33 is fixed on the inner wall of the sealed spraying box 1. The lead screw 7 passes through one side of the connecting bracket 5 and is installed by thread engagement. The top end of the lead screw 7 is coaxially and fixedly connected to the output end of the stepper motor 6. The bottom end of the lead screw 7 is coaxially fixedly connected to a rotating shaft 32. The bottom end of the rotating shaft 32 is embedded and rotatably installed inside the bottom wall of the inclined groove 4. A positioning seat 8 is sleeved on the outside of the rotating shaft 32 and rotatably installed. One end of the positioning seat 8 is fixedly installed on the inner wall of the sealed spraying box 1. Auxiliary rods 9 are vertically and slidably installed inside both sides of the connecting frame 5 near the stepper motor 6. The bottom end of the auxiliary rod 9 is embedded and fixed on the bottom wall of the inclined groove 4. An auxiliary seat 10 is fixedly installed on the top end of the auxiliary rod 9. One end of the auxiliary seat 10 is fixedly installed on the inner wall of the sealed spraying box 1. A slider 35 is slidably mounted on the outer side of the positioning rod 12 near the top. An installation block 13 is fixed to one end of the slider 35. A limit rod 14 is vertically fixed inside the installation block 13. A stop block 31 is fixed to the top of the positioning rod 12. A positioning bolt 34 is threaded between the installation block 13 and the connecting frame 5. The bottom end of the sealing block 15 is fixed with a spray block 19 of the same material as the bottom wall of the sealing spray box 1. The top of the sealing block 15 is fitted with a retaining ring 16. The bottom end of the retaining ring 16 is embedded with a rubber ring 18. The bottom wall of the inclined groove 4 near the rubber ring 18 is provided with a first annular sealing groove 17. A rotating rod 20 is rotatably installed inside the bottom end of the sealed spraying box 1. An auxiliary handle 21 is fixed to one end of the rotating rod 20 near the box door 2. A first bevel gear 22 is fixed to the other end of the rotating rod 20. A second bevel gear 23 is sleeved and fixed to the outside of the rotating shaft 32. The first bevel gear 22 and the second bevel gear 23 are meshed and connected. In this embodiment, under normal conditions, the bottom plate of the sealed spray-painted box 1 is fully covered and sealed by a composite process of epoxy zinc-rich paint and polyurethane sealant. The sealing block 15 is completely inserted into the drain hole 11, and the spray-painted block 19 at its bottom end is spray-painted with the same material as the bottom wall of the box, ensuring the continuity and integrity of the overall sealing layer of the bottom plate and fully retaining the core advantage of the existing fully spray-painted sealing structure in preventing external moisture intrusion. At the same time, the rubber ring 18 at the bottom end of the retaining ring 16 is tightly embedded in the first annular sealing groove 17, forming the first reliable end face seal, effectively preventing external moisture and water from seeping back into the box through the gap between the drain hole 11 and the sealing block 15, fundamentally solving the technical problem of moisture backflow in the existing normally open drain hole 11.
[0022] When water accumulates inside the enclosure, regardless of whether the water originates from aging and leakage of the cabinet door seal, condensation from ventilation, rising moisture from the cable trench, or introduction during installation and maintenance, it will automatically flow into the inclined groove 4 surrounding the main cabinet 3 under gravity, preventing water accumulation dead zones in other areas of the base plate. When the water level in the inclined groove 4 reaches a set threshold, the liquid level sensor 36 sends a signal to the control unit, which drives the stepper motor 6 to rotate, causing the lead screw 7 to rotate synchronously. Under the vertical guidance of the auxiliary rod 9, the connecting frame 5 rises smoothly along the lead screw 7, and through the positioning bolt 34, drives all the mounting blocks 13 and sliders 35 to slide upwards synchronously along the positioning rod 12, thereby causing all the sealing blocks 15 to rise synchronously away from the drain holes 11, making all the drain holes 11 fully open at the same time. The water in the inclined groove 4 is quickly discharged outside the enclosure through the drain holes 11, solving the fundamental defect of existing fully sprayed sealed base plates where water cannot be discharged, leading to metal corrosion and insulation aging due to long-term accumulation, and minimizing the damage of water accumulation to the equipment.
[0023] Once the accumulated water is drained, the liquid level sensor 36 sends a reset signal to the control unit. The control unit then drives the output shaft of the stepper motor 6 to rotate in the reverse direction, causing the lead screw 7 to rotate synchronously in the reverse direction. The connecting frame 5 descends smoothly along the auxiliary rod 9, causing all the sealing blocks 15 to be inserted into the drain hole 11 simultaneously. When the rubber ring 18 at the bottom of the retaining ring 16 is fully embedded in the first annular sealing groove 17 and pressed tightly, the stepper motor 6 stops rotating, and the system returns to its normal sealing state. The entire drainage and sealing process is completed automatically without manual intervention, significantly reducing the frequency of maintenance personnel opening the cover to check for accumulated water, reducing the workload of manually cleaning the drain hole 11, and thus reducing the maintenance cost and workload of the outdoor ring network box. At the same time, the system adopts the design logic of "low water level triggering and rapid drainage" to ensure that the accumulated water is drained in time before it causes harm, effectively avoiding serious power supply accidents such as short circuit tripping and equipment burnout caused by water accumulation.
[0024] When the electric drive system malfunctions due to power outages, stepper motor 6 failures, or other special circumstances, maintenance personnel can open the cabinet door 2 and rotate the auxiliary handle 21 located at the bottom of the cabinet. This rotates the rotating rod 20 synchronously, and through the meshing transmission of the first bevel gear 22 and the second bevel gear 23, drives the rotating shaft 32 and the lead screw 7 to rotate. This allows for manual control of the lifting and lowering of the connecting frame 5, enabling manual opening and closing of the drain hole 11. This purely mechanical emergency drive structure is completely independent of the electric system and requires no power supply or electronic components. It can operate reliably even when the sealed spraying cabinet 1 is completely powered off, ensuring timely drainage of water accumulated inside the sealed spraying cabinet 1 under any extreme conditions. This prevents equipment failure due to water accumulation, significantly improving the overall reliability of the system.
[0025] Example 2: Please refer to Figures 9-11This embodiment further illustrates Example 1, wherein a waterproof component is provided inside the sealing block 15.
[0026] The waterproof assembly includes an air storage chamber 24 and a piston block 25. The air storage chamber 24 is opened inside the sealing block 15. The piston block 25 is slidably and sealingly installed inside the air storage chamber 24. The bottom end of the limiting rod 14 penetrates the top wall of the sealing block 15 and is slidably installed inside the air storage chamber 24. One end of the limiting rod 14 located inside the air storage chamber 24 is fixedly connected to the top end of the piston block 25. A limiting spring 26 is sleeved on the outside of the limiting rod 14. The two ends of the limiting spring 26 are respectively fixedly installed on the outside of the bottom end of the slider 35 and the outside of the top end of the sealing block 15. An annular mounting groove 28 is opened around the outside of the sealing block 15 near the bottom of the gas storage chamber 24. The annular mounting groove 28 is surrounded by a sealing airbag 29. Several air guide pipes 27 are fixedly connected to the side of the sealing airbag 29 near the air storage chamber 24. The end of each air guide pipe 27 away from the sealing airbag 29 passes through and is fixedly installed inside the bottom of the air storage chamber 24. A second annular sealing groove 30 is formed on the inner wall of the drain hole 11 near the bottom.
[0027] In this embodiment, the waterproof component adopts a self-driven graded sealing and frictionless opening integrated design. Based on the end face sealing in Embodiment 1, a dynamic adaptive airbag soft seal is added to form a dual sealing protection system, which solves the industry problem that the sealing reliability and service life of existing sealing structures cannot be achieved simultaneously.
[0028] When the stepper motor 6 drives the connecting frame 5 to descend and insert the sealing block 15 into the drain hole 11, the rubber ring 18 at the bottom of the retaining ring 16 first embeds into the first annular sealing groove 17 and is pressed tightly to form the first end face seal. At this time, the sealing block 15 stops moving downward, and the connecting frame 5 continues to drive the slider 35 and the limiting rod 14 to move downward, compressing the limiting spring 26. At the same time, the limiting rod 14 drives the piston block 25 to slide downward in the air storage chamber 24, so that the air in the air storage chamber 24 is evenly pressed into the sealing airbag 29 through multiple air guide pipes 27. At this time, the annular mounting groove 28 and the second annular sealing groove 30 are precisely aligned. After the sealing airbag 29 is compressed and expanded, it is completely embedded in the second annular sealing groove 30, forming the second radial soft seal. The two seals work together, and the sealing effect is significantly better than the existing single sealing structure, which can effectively resist the backflow of water and moisture penetration under extreme rainstorms.
[0029] When drainage is needed, the stepper motor 6 drives the connecting frame 5 to rise, first moving the slider 35 and the limiting rod 14 upwards. The limiting spring 26 gradually rebounds, and at the same time, the limiting rod 14 drives the piston block 25 to slide upwards within the air storage chamber 24, creating a negative pressure within the air storage chamber 24. This draws all the air from the sealing airbag 29 back into the air storage chamber 24 through the air guide pipe 27. The sealing airbag 29 fully retracts into the annular mounting groove 28, disengaging from the second annular sealing groove 30. Only when the connecting frame 5 continues to rise will it cause the sealing block 15 to be lifted away from the drain hole 11.
[0030] This frictionless opening design, which involves first contracting the airbag and then raising the block, avoids direct friction between the seal and the inner wall of the drain hole 11. It solves the technical defects of existing rubber seals, such as wear, aging, and seal failure after repeated opening and closing, significantly extending the seal life to match the design life of the ring main body. Simultaneously, the expansion pressure of the sealing airbag 29 is automatically controlled by the displacement of the piston block 25, adapting to minor deformations and wear on the sealing surface to maintain optimal sealing. The sealing and opening actions of the waterproof components are entirely driven by the mechanical structure itself, requiring no additional air or hydraulic power source or independent electronic control unit, resulting in a simple and reliable structure. After the accumulated water is drained, the stepper motor 6 drives the connecting frame 5 to descend, repeating the sealing process, and the system returns to its normal double-sealed state.
