Description

Technical Field

[0001] The present invention relates to the technical field of ring net boxes, in particular to a leakage-proof primary and secondary fused complete ring net box. Background Art

[0002] The integrated primary and secondary ring main unit (RME) is a key component in achieving intelligent upgrades in distribution networks. Its core lies in the deep integration and collaborative design of the primary equipment responsible for power transmission and distribution in the power system, and the secondary equipment responsible for system regulation, safety protection, and information exchange. The primary equipment, including high-voltage circuit breakers, load switches, disconnectors, busbars, and other high-voltage main circuit electrical components, is the physical carrier of power flow. The secondary equipment, including intelligent controllers, protective relays, condition monitoring sensors, and communication modules, constitutes the nerve center of the system. Through its integrated design, the two types of equipment break through the limitations of traditional split-type layouts and achieve a high degree of integration of electrical connection, signal exchange, and functional coordination. This equipment performs multiple core functions, not only accurately distributing power within the region and ensuring power supply to various load nodes, but also leveraging the intelligent algorithms of the secondary equipment to quickly locate the fault point and automatically isolate the faulty section in the event of a grid fault, preventing the incident from escalating and significantly shortening the power outage. With its high reliability and intelligent features, this equipment is a key support for improving the reliability of distribution network power supply and adapting to the transformation of the energy structure.

[0003] The prior art publication number: CN119852860B discloses a leakage-proof primary and secondary fusion ring network box, which relates to the technical field of ring network boxes, including a ring network box body and an air duct, wherein both ends of the air duct are respectively connected to the air inlet and the air outlet opened at the upper end of the ring network box body, and multiple heat dissipation fans are fixed on the side of the exhaust port away from the air duct; the ring network box body is divided into multiple installation rooms by multiple inner partitions, and the air duct is provided with an air outlet on the side close to the installation room; the inside of the air duct is divided into multiple chambers by multiple outer partitions, and each chamber corresponds to the installation room; an air flow path switching component is provided on the air duct, and the air flow path switching component includes a sealing plate slidably arranged on the lower surface of the air duct, and the sealing plate is provided with multiple corresponding holes adapted to the air outlet; the problem of condensation and water accumulation inside the ring network box due to moisture permeability of the heat dissipation holes causes metal corrosion, circuit board moisture and sensor misjudgment, threatening equipment safety is solved.

[0004] If there is water accumulation at the installation location of the existing ring network box, such as rainwater accumulation or poor ground drainage, the water will wrap around the bottom of the box layer by layer, forming a state of continuous immersion. Over time, the sealing structure at the bottom of the box will gradually fail under the erosion of water, and moisture will slowly penetrate into the interior of the box through the gaps. The equipment in the box should operate in a dry environment. Once it is affected by moisture, the insulation performance will be greatly reduced, and there will be risks such as corrosion of metal parts and short circuits of circuits, which will greatly shorten the service life of the equipment, increase the maintenance frequency and cost, and bring a series of chain problems to the safe operation of the ring network box. This is a common safety hazard in the operation of the ring network box. Summary of the Invention

[0005] The purpose of the present invention is to provide a leakage-proof primary and secondary fusion ring network box to solve the problem that if the existing ring network box is continuously soaked due to water accumulation at the installation location, the water will slowly penetrate into the interior of the box through the gaps, greatly shortening the service life of the equipment.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A leakage-proof primary and secondary fused ring mesh box comprises a box body, the bottom end of the box body is fixedly connected to a base, the inner wall of the base is fixedly connected to a guide plate which is tilted with the left side higher and the right side lower, the right end of the guide plate is rotatably connected to a water retaining flap, the size of the water retaining flap is adapted to the distance between the lowest point of the guide plate and the right inner wall of the base, a flared opening is provided on the left side of the base, the left end of the guide plate is located above the flared opening, a drain outlet is provided on the right side of the base, the position of the drain outlet is higher than the water retaining flap, and a drain pipe connected to the drain outlet is installed on the right side of the base.

[0008] Preferably, a left water inlet is opened on the left side of the base, and the left water inlet is located above the left end of the guide plate. A right water inlet is opened on the right side of the base, and the right water inlet is at the same height as the left water inlet.

[0009] Preferably, the front and rear ends of the base are both rotatably connected to flow guides, the two flow guides are symmetrically arranged, and the lowest end of the flow guides faces the left side of the base.

[0010] Preferably, a top surface of the guide plate close to the right end is fixedly connected to a support rod, and a top end of the support rod is fixedly connected to the bottom of the box body.

[0011] Preferably, a support block is fixedly connected to the right inner wall of the base, and the support block is used to support the unfolded water retaining flap.

[0012] Preferably, a water retaining eave is fixedly connected to the bottom end of the box body, and the water retaining eave is used to prevent surrounding accumulated water from overflowing the bottom of the box body.

[0013] Preferably, a second motor is fixedly mounted on the front end of the base, and the second motor is used to drive the water retaining flap to flip.

[0014] Preferably, the front and rear ends of the base are fixedly connected to first motors, and the two first motors respectively drive the guide channels on the corresponding sides to rotate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A multi-layered anti-leakage system is formed through the coordination of guide plates, water-retaining flaps, sealing gaskets and other structures. When the water level is low, the water-retaining flaps fold, and the accumulated water can be quickly discharged directly through the drain outlet to meet daily drainage needs. When the water level is medium or high, the water-retaining flaps unfold to block the spread path.

[0017] 2. The design of the front and rear guide channels solves the problem of uneven water distribution around the base. When water accumulates on the front and rear sides of the base, the first motor drives the guide channels to expand, guiding the water to the left side of the base, preventing the water from being unable to drain out and seeping into the bottom of the box.

[0018] 3. The support rod connects the guide plate and the bottom of the box, and the support block assists in supporting the unfolded water retaining flap, thereby enhancing the structural strength of key components and ensuring that they are not easily deformed during long-term use.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 5 , the present invention provides a technical solution.

[0028] A leakage-proof primary and secondary fusion ring network box includes a box body 1. The bottom end of the box body 1 is fixedly connected to a base 2. The base 2 serves as a bearing foundation and realizes leakage prevention through the cooperation of an internal guide structure and an external interface. The inner wall of the base 2 is fixedly connected to a guide plate 4 that is tilted and set higher on the left and lower on the right, which is used to converge water that has seeped into the base 2 to the right. The right end of the guide plate 4 is rotatably connected to a water-retaining flap 5. The size of the water-retaining flap 5 is adapted to the distance between the lowest point of the guide plate 4 and the right inner wall of the base 2. When closed, it can block external water.

[0029] A flare 16 is provided on the left side of the base 2, and the left end of the guide plate 4 is located above the flare 16. A drain outlet 7 is provided on the right side of the base 2, and the position of the drain outlet 7 is higher than the water retaining flap 5. A drain pipe 8 connected to the drain outlet 7 is installed on the right side of the base 2 for discharging the accumulated water after the flip.

[0030] A left water inlet 3 is provided on the left side of the base 2, and the left water inlet 3 is located above the left end of the guide plate 4. A right water inlet 9 is provided on the right side of the base 2, and the right water inlet 9 is at the same height as the left water inlet 3. The water introduced from the left water inlet 3 and the right water inlet 9 can directly fall on the guide plate 4 and flow in the inclined direction.

[0031] The front and rear ends of the base 2 are both rotatably connected to the guide channels 11. The two guide channels 11 are arranged symmetrically, and the lowest end of the guide channel 11 faces the left side of the base 2, which can guide the water accumulated on the front and rear sides of the base 2 to the left side of the base 2.

[0032] A second motor 14 is fixedly installed at the front end of the base 2. The second motor 14 is used to drive the water-retaining flap 5 to flip. When external water needs to be blocked, the water-retaining flap 5 rotates and expands to close the gap between the lowest point of the guide plate 4 and the right inner wall of the base 2. In order to enhance the sealing of the closed state, a sealing gasket can be installed at the connection between the guide plate 4 and the water-retaining flap 5 to prevent leakage in the gap.

[0033] The front and rear ends of the base 2 are fixedly connected to the first motor 13, and the two first motors 13 respectively drive the guide channel 11 on the corresponding side to rotate. Considering that the environment around the base 2 is humid, in order to ensure the stable operation of the motor, the first motor 13 and the second motor 14 can be adaptively equipped with a waterproof cover on the outside of the motor, or directly use a waterproof motor to avoid damage due to moisture.

[0034] The top surface of the guide plate 4 near the right end is fixedly connected to a support rod 12, and the top end of the support rod 12 is fixedly connected to the bottom of the box body 1 to ensure the stability of the connection of the guide plate 4.

[0035] A support block 6 is fixedly connected to the right inner wall of the base 2. The support block 6 is used to support the unfolded water retaining flap 5. When the water retaining flap 5 is unfolded, it can overlap on the support block 6 to increase the stability of the water retaining flap 5.

[0036] The bottom end of the box body 1 is fixedly connected to a water retaining eaves 10, which is used to prevent the surrounding accumulated water from overflowing the bottom of the box body 1. Like the closed water retaining flap 5, it is also used to block the water flow away from the box body 1. If it is to cooperate with the anti-seepage structure of the box body 1 surface in the prior art, it can be adaptively improved by setting the top surface of the water retaining eaves 10 to an inclined state so that rainwater or seepage water falling on its top surface can be quickly discharged to the outside along the inclined direction.

[0037] A box top 15 is fixedly connected to the top of the box body 1 .

[0038] The drainage process is divided into three stages according to the water level, as follows:

[0039] Phase 1: Please refer to Figure 6 When the depth of water accumulation around the box body 1 does not exceed the height of the drain outlet 7, the water retaining flap 5 is controlled to flip and fold to the upper end of the guide plate 4. At this time, the accumulated water in the base 2 can be discharged directly from the drain outlet 7. The drain pipe 8 needs to be set with a slope according to the terrain of the installation site, from high to low, to ensure that the water flows smoothly into the water tank or sewer.

[0040] The second stage: when the water level rises to a level higher than the drain outlet 7, the water retaining flap 5 is controlled to flip and unfold and overlap the support block 6. At this time, the water retaining flap 5 can block the accumulated water from spreading to the guide plate 4 area, forcing the accumulated water to flow through other paths, avoiding the accumulated water from spreading to the bottom of the box 1 and causing the bottom of the box 1 to be flooded.

[0041] The third stage: when the water level continues to rise to the height of the left water inlet 3 and the right water inlet 9, the external accumulated water flows into the guide plate 4 area through the two water inlets and is discharged through the drain outlet 7. The water inlet diameter is adapted to the drain outlet 7 by design to ensure that the water inlet flow does not exceed the drainage capacity, thereby avoiding the formation of a water layer between the box body 1 and the guide plate 4, and preventing the bottom of the box body 1 from being soaked. At the same time, combined with the blocking of the water around the box body 1 by the water retaining eaves 10, the accumulated water is further forced to flow to other paths. At this stage, the water level is close to the warning value. If the water level continues to rise, artificial auxiliary drainage must be started in time. Among the above three stages, the first stage is the normal working condition. In daily use, drainage and anti-leakage work is mainly completed through this stage.

[0042] The guide channel 11 is in the terrain where the accumulated water is mainly concentrated in the front and rear sides of the base 2. Start the first motor 13 to drive the guide channel 11 to expand, so as to guide the accumulated water in the front and rear sides of the base 2 to flow to the left side of the base 2, so that the accumulated water is evenly distributed. Then, as described above, the left water inlet 3 on the left side of the base 2 can be used to introduce the accumulated water into the interior of the base 2, and processed through the internal drainage structure, such as the guide plate 4, the water retaining flap 5, and the drain outlet 7, to prevent the water in the front and rear sides of the base 2 from being unable to be handled.

[0043] This solution is specifically as follows: daily routine drainage, in the first stage, during daily use, when the water level around the ring network box does not exceed the height of the drain outlet 7, the equipment is in a normal drainage condition, the water retaining flap 5 is folded to the upper end of the guide plate 4, and the gap between the lowest point of the guide plate 4 and the right inner wall of the base 2 is unobstructed. A small amount of accumulated water in the base 2 is discharged from the drain outlet 7 through the drainage pipe 8 with a preset slope into the water tank or sewer, achieving daily leakage prevention. At this time, there is less water on the front and rear sides of the base 2, and the guide channel 11 remains in a retracted state, without the need for additional guidance.

[0044] In the second stage of drainage at the middle water level, the second motor 14 is used to control the water retaining flap 5 to flip and unfold, so that it is overlapped with the support block 6, blocking the spread of accumulated water to the guide plate 4 area, and preventing the accumulated water from soaking the bottom of the box body 1. The first motors 13 on the front and rear sides are started to drive the guide channel 11 to unfold, guiding the accumulated water on the front and rear sides of the base 2 to flow to the left side of the base 2.

[0045] In the third stage of high water level emergency drainage, the external accumulated water flows into the guide plate 4 area through the left water inlet 3 and the right water inlet 9 at the same time. The accumulated water gathers to the right along the guide plate 4 and is quickly discharged through the drain outlet 7 and the drain pipe 8. The water retaining eaves 10 at the bottom of the box 1 force the accumulated water to flow to other paths, blocking the surrounding accumulated water from spreading to the top of the box 1. At this stage, the water level is close to the warning value. If the water level continues to rise, it is necessary to start manual auxiliary drainage in time, such as an external water pump, to prevent the accumulated water from exceeding the equipment protection limit.

[0046] Regularly clean the debris on the guide plate 4 and the guide channel 11, check whether the sealing gasket is aging, and replace it in time if it is damaged, ensure the sealing of the water retaining flap 5 when it is closed, check whether the drain pipe 8 is blocked or damaged, ensure smooth drainage, maintain the equipment, and ensure that the anti-leakage function is continuously reliable. Through the above use process, the ring network box achieves efficient anti-leakage and protects the safe operation of the box body 1 and the internal equipment.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
