Description

Technical Field

[0001] This invention relates to the field of ring network box technology, specifically to a primary and secondary integrated ring network box. Background Technology

[0002] Integrated primary and secondary ring main units are key equipment in distribution network automation systems. Their core lies in the deep integration of traditionally independent primary equipment (such as load switches, circuit breakers, and instrument transformers) with secondary equipment (such as distribution terminal units (DTUs), communication modules, and power systems) during the design and manufacturing stages, forming a compact and fully functional intelligent complete unit. Current mainstream products adopt a highly integrated design concept, typically arranging multiple functional circuit units side-by-side in a modular form. This design mode significantly reduces equipment size and footprint, enables factory prefabrication and commissioning, and significantly improves the standardization level and operational reliability of distribution network equipment, making it an important physical carrier for building smart distribution networks.

[0003] However, this highly integrated structural design makes the entire enclosure a rigidly connected whole system. This makes it difficult to effectively dissipate any impact and vibration energy from the external environment (such as transportation bumps, ground disturbances or accidental impacts) or internal operations. It is easily transmitted to all the precision equipment inside the enclosure through the frame structure. The independent buffering capacity of each piece of equipment under the traditional distributed layout no longer exists, which puts forward higher requirements for the overall structural strength and rigidity of the enclosure and the vibration-resistant fixing method of the internal components. Summary of the Invention

[0004] The purpose of this invention is to provide a primary and secondary integrated ring network box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a primary and secondary integrated ring network box, comprising a base, an outdoor box mounted on the base, and a pad plate inside the base; the pad plate, from top to bottom, comprises a secondary equipment compartment, an operating mechanism compartment, and a primary equipment compartment mounted via an integrated frame; a fixing plate is fixedly installed on the top wall of the outdoor box, and a pressure-resistant plate corresponding to the fixing plate is fixedly installed on the top of the secondary equipment compartment; multiple sets of circumferentially distributed air pumping grooves are formed in the fixing plate, and a slidable cup is connected in each air pumping groove, with a fixing rod at the bottom of the slid cup; a limiting groove is formed on the fixing plate, and a limiting rod is inserted into the limiting groove; a first sealing rod and a second sealing rod are respectively provided in the limiting groove, and an exhaust groove one and an exhaust groove two are respectively formed on the limiting rod, the exhaust groove one and the exhaust groove two corresponding to the first sealing rod and the second sealing rod, respectively.

[0006] Furthermore, the outdoor box is equipped with multiple doors, and the integrated frame is installed inside the outdoor box, with multiple sets of the integrated frame arranged side by side.

[0007] Furthermore, the fixing rod is fixedly connected to the pressure-resistant plate, the limiting rod is fixedly connected to the pressure-resistant plate, the limiting rod is located at the center of the pressure-resistant plate, and multiple sets of the fixing rods are located at the edge of the pressure-resistant plate.

[0008] Furthermore, a buffer groove is provided on the base, a receiving groove is provided inside the buffer groove, an exhaust pipe is provided inside the receiving groove, and the exhaust pipe is located at the upper part of the receiving groove.

[0009] Furthermore, the bottom of the pad is provided with a retraction rod, which is inserted into the buffer groove. A buffer spring is provided between the pad and the base, and the buffer spring is fitted onto the retraction rod.

[0010] Furthermore, the bottom of the retraction rod is provided with an adjusting rod corresponding to the receiving groove, and a second buffer spring is provided between the retraction rod and the bottom wall of the buffer groove, the second buffer spring being sleeved on the adjusting rod.

[0011] Furthermore, multiple sets of the pump air slots are connected by a venting slot, which is annular and located at the upper end of the pump air slot.

[0012] Furthermore, a buffer spring three is provided between the fixed plate and the pressure-resistant plate, and the buffer spring three is sleeved on the fixed rod. The length of the second sealing rod is greater than that of the first sealing rod.

[0013] Furthermore, an air supply pipe is provided between each pair of adjacent fixed plates, and the air supply pipe is connected to the air pump slots in the two adjacent fixed plates respectively. An air collection pipe is connected in the middle of the air supply pipe. Airbag 1, airbag 2, and airbag 3 are arranged sequentially from top to bottom below the air collection pipe. Airbag 1, airbag 2, and airbag 3 are connected by a connecting pipe. An air outlet pipe is provided at the bottom of airbag 3, and a branch pipe is connected to the air outlet pipe.

[0014] Furthermore, the first airbag is located between two adjacent secondary equipment compartments, the second airbag is located between two adjacent operating mechanism compartments, the third airbag is located between two adjacent primary equipment compartments, and the branch pipes are respectively connected to the bottom of two adjacent primary equipment compartments.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This ring main unit adopts a three-stage vibration reduction structure of "buffer springs (buffer spring one and buffer spring two) for primary energy absorption, gas damping (buffer groove and containment groove) for moderate vibration control, and airbags (airbag one, airbag two, and airbag three) for isolation and vibration reduction". It can provide adaptive vibration reduction solutions for vibrations of small, medium and large amplitudes, solve the problem of easy vibration transmission caused by the rigid connection of traditional integrated ring main units, and effectively protect the operational stability of precision electronic components in the secondary equipment compartment and high-voltage components in the primary equipment compartment.

[0016] 2. This ring network box converts vibration energy into airbag inflation power. The airbag inflation not only achieves vibration isolation, but also exhausts heat to the primary equipment compartment through the branch pipe during continuous large-amplitude vibration. This specifically solves the potential problem of "vibration indirectly damaging the effectiveness of the heat dissipation system", avoids equipment failure due to overheating, and eliminates the need for additional heat dissipation drive components, simplifying the structure and reducing energy consumption.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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] This invention provides a technical solution: such as Figures 1-8The illustrated primary and secondary integrated ring network box includes a base 1, an outdoor box 2 mounted on the base 1, and a pad 4 inside the base 1. The pad 4 has, from top to bottom, a secondary equipment compartment 6, an operating mechanism compartment 7, and a primary equipment compartment 8, all mounted via an integrated frame 5. A fixing plate 9 is fixedly installed on the top wall of the outdoor box 2, and a pressure-resistant plate 10 corresponding to the fixing plate 9 is fixedly installed on the top of the secondary equipment compartment 6. Multiple sets of circumferentially distributed air pumping grooves 23 are formed within the fixing plate 9, and a slidable cup 26 is connected within each air pumping groove 23. A fixing rod 25 is provided at the bottom of the cup 26. A limiting groove 20 is formed on the fixing plate 9, and a limiting rod 28 is inserted into the limiting groove 20. A first sealing rod 21 and a second sealing rod 22 are respectively provided within the limiting groove 20. An exhaust groove 1 29 and an exhaust groove 20 30 are respectively formed on the limiting rod 28, corresponding to the first sealing rod 21 and the second sealing rod 22. The outer box 2 is equipped with multiple boxes 3, and the integrated frame 5 is set inside the outdoor box 2. Multiple sets of integrated frames 5 are arranged side by side. The fixing rod 25 is fixedly connected to the pressure-resistant plate 10, and the limiting rod 28 is fixedly connected to the pressure-resistant plate 10. The limiting rod 28 is set at the center of the pressure-resistant plate 10, and multiple sets of fixing rods 25 are set at the edge of the pressure-resistant plate 10. The base 1 is provided with a buffer groove 13, and a receiving groove 14 is provided in the buffer groove 13. An exhaust pipe 15 is provided in the receiving groove 14 and is set at the upper part of the receiving groove 14. The bottom of the pad 4 is provided with a retraction rod 11, which is inserted into the buffer groove 13. A buffer spring 12 is provided between the pad 4 and the base 1 and is sleeved on the retraction rod 11. The bottom of the retraction rod 11 is provided with an adjusting rod 16 corresponding to the receiving groove 14. A buffer spring 17 is provided between the retraction rod 11 and the bottom wall of the buffer groove 13 and is sleeved on the adjusting rod 16.

[0021] In this embodiment, the base 1 serves as the basic support structure of the ring network box. The buffer groove 13 and the receiving groove 14 inside the base 1 form a nested cavity structure, which are coaxially distributed to provide a spatial carrier for the realization of the gas damping effect. The retraction rod 11 at the bottom of the pad 4 is in sliding fit with the buffer groove 13 to ensure that the pad 4 can move smoothly in the vertical direction during vibration and avoid component jamming caused by lateral displacement. The buffer spring 12 is sleeved on the outside of the retraction rod 11, with one end tightly abutting the bottom of the pad 4 and the other end fixed to the upper surface of the base 1. In the initial state, it is in a slightly compressed state and can directly support the weight of the pad 4 and the equipment compartment above it. When small-amplitude vibration occurs, it can quickly absorb some vibration energy through its own elastic deformation.

[0022] The adjusting rod 16 at the bottom of the retraction rod 11 and the receiving groove 14 are also in sliding fit, with its outer diameter precisely matching the inner diameter of the receiving groove 14 to ensure gas sealing. The second buffer spring 17 is sleeved on the outside of the adjusting rod 16, connecting the bottom of the retraction rod 11 to the bottom wall of the buffer groove 13, forming a double-layer elastic support structure with the first buffer spring 12. The two work together to further disperse vibration energy and avoid elastic fatigue caused by excessive load on a single spring. In addition, the exhaust pipe 15 at the top of the receiving groove 14 penetrates the side wall of the base 1, and its opening direction avoids the interior of the outdoor box 2 to prevent dust or moisture carried by the exhaust gas from affecting the equipment inside the box. At the same time, it ensures that the air in the buffer groove 13 can be smoothly discharged during small vibrations without adding extra damping burden.

[0023] The integrated frame 5 is made of lightweight, high-strength materials. The multiple sets of frames arranged side-by-side have uniform gaps between them, facilitating independent installation and disassembly of each equipment compartment and providing space for the subsequent placement of airbag components. The outdoor enclosure 2 has multiple doors 3 corresponding to the front and side positions, each equipped with a sealing strip and safety lock. This ensures ease of maintenance while effectively isolating outdoor rainwater, dust, and other impurities, maintaining the stability of the operating environment for the equipment inside the enclosure.

[0024] refer to Figures 1-8 Multiple sets of air pumping slots 23 are connected by air venting slots 24, which are annular and located at the upper end of the air pumping slots 23. A buffer spring 27 is provided between the fixed plate 9 and the pressure-resistant plate 10, and the buffer spring 27 is sleeved on the fixed rod 25. The length of the second sealing rod 22 is greater than that of the first sealing rod 21. An air supply pipe 18 is provided between every two adjacent fixed plates 9, connecting the air pumping slots 23 within the two adjacent fixed plates 9. A gas collecting pipe 19 is connected to the middle of the air supply pipe 18. Below, from top to bottom, are arranged airbag 1 31, airbag 2 32, and airbag 33. Airbag 1 31, airbag 2 32, and airbag 33 are connected by connecting pipe 34. Airbag 33 has an air outlet pipe 35 at its bottom, and a branch pipe 36 is connected to the air outlet pipe 35. Airbag 1 31 is located between two adjacent secondary equipment compartments 6, airbag 2 32 is located between two adjacent operating mechanism compartments 7, and airbag 33 is located between two adjacent primary equipment compartments 8. The branch pipe 36 is connected to the bottom of the two adjacent primary equipment compartments 8 respectively.

[0025] In this embodiment, both the fixing plate 9 and the pressure-resistant plate 10 are made of rigid materials and are arranged in parallel to each other to ensure that the force can be evenly distributed during the vibration transmission process. The multiple sets of pumping grooves 23 in the fixing plate 9 are distributed in a circle. This layout can make the compressed gas generated by the cup 26 during sliding evenly collect, avoiding the problem of uneven inflation of the airbag caused by excessively high or low local gas pressure. The annular venting groove 24 is opened at the upper end of the pumping groove 23, connecting all the pumping grooves 23 into a whole air passage to ensure that the gas can be quickly and smoothly delivered to the air supply pipe 18.

[0026] The cup 26 is made of a highly elastic and wear-resistant sealing material. Its edge fits tightly against the inner wall of the pump groove 23, forming a reliable sealing structure to prevent gas leakage from affecting the pumping efficiency. The two ends of the fixing rod 25 are rigidly connected to the cup 26 and the pressure plate 10, respectively, to ensure that the vibration energy of the pressure plate 10 is completely transmitted to the cup 26, driving the cup 26 to slide stably within the pump groove 23. The buffer spring 27 is sleeved on the outside of the fixing rod 25. Its elastic coefficient is precisely matched, which can provide a certain support force for the pressure plate 10 in the early stage of vibration, reducing the impact of vibration on the fit gap between the cup 26 and the pump groove 23, and can quickly drive the pressure plate 10 and the cup 26 to reset after vibration, ensuring that the components can work normally in the next vibration.

[0027] The limiting groove 20 is located at the center of the fixed plate 9. The sliding engagement between the limiting rod 28 and the limiting groove 20 restricts the lateral displacement of the pressure plate 10, preventing the diaphragm cup 26 from detaching from the pumping groove 23 due to lateral swaying. The first sealing rod 21 and the second sealing rod 22 are fixed to the inner wall of the limiting groove 20. The design of the difference in their lengths is the key to achieving damping gradation: the shorter first sealing rod 21 corresponds to the damping adjustment for medium-amplitude vibrations, while the longer second sealing rod 22 corresponds to the damping adjustment for large-amplitude vibrations. Through cooperation with the exhaust groove on the limiting rod 28, the exhaust speed of the gas in the limiting groove 20 is precisely controlled, thereby achieving damping changes under different vibration scenarios.

[0028] The gas supply pipe 18 is made of flexible, pressure-resistant material, and its two ends are sealed to the ventilation slots 24 in the adjacent fixed plates 9 to ensure that the gas can be smoothly delivered from the pumping slot 23 to the gas collecting pipe 19. The gas collecting pipe 19 serves as a gas distribution hub, evenly distributing the gas to airbag 1 31, airbag 2 32, and airbag 33. The three airbags correspond to the gap positions of different equipment compartments. Airbag 1 31 is adapted to the precision characteristics of the secondary equipment compartment 6 and uses a softer material to reduce rigid impact. Airbag 33 is adapted to the high-pressure environment of the primary equipment compartment 8 and uses a high-temperature resistant and aging-resistant material to ensure safety. The connecting pipe 34 connects the three airbags to ensure that the inflation speed of the three is synchronized, avoiding uneven stress on the equipment compartment due to inflation differences. The port of the branch pipe 36 faces the heating components inside the primary equipment compartment 8 to ensure that the discharged gas can directly act on the heating area and improve the heat dissipation effect.

[0029] refer to Figures 1-8 Working principle: This integrated primary and secondary ring mesh enclosure utilizes a "graded vibration reduction and air-driven linkage" design to achieve precise response to vibrations of varying amplitudes, while simultaneously providing vibration isolation and auxiliary heat dissipation. The specific workflow is as follows: I. Small-amplitude vibration response stage: When the ring main is subjected to minor vibrations (such as slight transport bumps or outdoor ground breeze disturbances), the vibration energy is first transmitted to the base 1 and then acts on the pad 4. At this time, the buffer spring 12 and buffer spring 17 at the bottom of the pad 4 are rapidly compressed and deformed, absorbing part of the vibration energy through the conversion of elastic potential energy, thus slowing down the descent speed of the pad 4. Simultaneously, the pad 4 drives the retraction rod 11 to slide downward along the buffer groove 13. The air in the buffer groove 13 is compressed and then smoothly discharged through the exhaust pipe 15 at the top of the receiving groove 14, forming a mild gas damping effect, further weakening the remaining vibration energy and preventing the vibration from being directly transmitted to the upper equipment compartment.

[0030] During this process, the pressure plate 10 on top of the secondary equipment compartment 6 only experiences slight swaying, causing the limiting rod 28 to slide slightly within the limiting groove 20. Due to the small vibration amplitude, the sliding distance of the limiting rod 28 is limited, and neither the first sealing rod 21 nor the second sealing rod 22 is inserted into the corresponding exhaust groove 29 and exhaust groove 30. The gas in the limiting groove 20 can be quickly discharged through the two exhaust grooves. The overall damping is small, which achieves primary buffering while avoiding excessive damping that could cause unnecessary shaking in the equipment compartment, thus ensuring the stable operation of the precision components in the secondary equipment compartment 6.

[0031] II. Medium-amplitude vibration response stage: When the vibration amplitude increases (such as moderate impact or ground construction disturbance), the impact force on the pad 4 increases, and the descent amplitude increases accordingly. At this time, the compression of buffer spring 12 and buffer spring 17 reaches a large value, and the efficiency of elastic deformation in absorbing energy gradually decreases. The retraction rod 11 drives the adjusting rod 16 to be further inserted into the receiving groove 14. As the adjusting rod 16 goes deeper, its top end finally seals the exhaust pipe 15 at the top of the receiving groove 14, so that the buffer groove 13 and the receiving groove 14 form a relatively closed cavity.

[0032] The air inside the sealed cavity cannot be discharged through the exhaust pipe 15. As the pad 4 continues to descend, the gas pressure inside the cavity continuously increases, generating a reverse supporting force on the retraction rod 11 and the adjusting rod 16, hindering the pad 4 from descending further. The gas damping effect is significantly enhanced, rapidly weakening the energy of the medium-amplitude vibration. At the same time, the swaying amplitude of the pressure plate 10 increases, causing the limiting rod 28 to slide a greater distance within the limiting groove 20. The first sealing rod 21 is inserted into the first exhaust groove 29, blocking the exhaust channel. The gas in the limiting groove 20 can only be discharged through the second exhaust groove 30, slowing down the exhaust speed and further increasing the damping. This effectively limits the swaying amplitude of the secondary equipment compartment 6 and protects the mechanical components inside the operating mechanism compartment 7 from severe vibration.

[0033] III. Large-amplitude vibration response stage: When the vibration amplitude increases further and exceeds the handling capacity of the base 1 buffer assembly (such as severe impact or strong earthquake), the vibration energy is directly transmitted to the integrated frame 5, causing significant vibration in the secondary equipment compartment 6, operating mechanism compartment 7, and primary equipment compartment 8. At this time, the pressure plate 10 on the top of the secondary equipment compartment 6 moves up and down synchronously with the equipment compartment, causing the fixed rod 25 to move axially along the air pumping groove 23. The cup 26 at the top of the fixed rod 25 slides in the air pumping groove 23, compressing the air in the air pumping groove 23 like an air pump.

[0034] Compressed air is collected through an annular ventilation channel 24, transported to a collecting pipe 19 via an air supply pipe 18, and then distributed by the collecting pipe 19 to airbag 31, airbag 32, and airbag 33. Since the three airbags are connected by a connecting pipe 34, gas is simultaneously injected into the airbags, causing them to expand rapidly and fill the gaps between adjacent equipment compartments, forming a flexible isolation layer. The expanded airbags not only block the transmission of vibration between different equipment compartments, preventing the vibrations of the secondary equipment compartment 6 and the primary equipment compartment 8 from affecting each other, but also further absorb vibration energy through their own elastic deformation, significantly reducing the impact of vibration on the equipment.

[0035] During this process, the limiting rod 28 slides to its maximum extent within the limiting groove 20, and the second sealing rod 22 is inserted into the second exhaust groove 30. Both exhaust grooves are blocked, and the gas in the limiting groove 20 can only be slowly discharged through the tiny gap between the limiting rod 28 and the limiting groove 20. The damping reaches its maximum value, which limits the movement of the pressure-resistant plate 10 to the maximum extent, ensuring that the cup 26 always slides stably within the pumping groove 23 and continuously supplies air to the airbag.

[0036] IV. Response stage of sustained large-amplitude vibration: If large-scale vibrations continue, the rubber cup 26 will continue to slide within the air pumping groove 23, continuously supplying compressed air into the airbags until airbag 1 31, airbag 2 32, and airbag 33 are all filled with gas and can no longer expand. At this point, the compressed air continuously generated within the air pumping groove 23, having nowhere to be contained, will enter the branch pipe 36 through the air outlet pipe 35 at the bottom of airbag 33, and then be discharged into the adjacent primary equipment compartment 8 through the port of the branch pipe 36.

[0037] The gas entering the primary equipment compartment 8 forms a flowing airflow, which can carry away the heat generated by the high-voltage equipment inside the compartment during operation. Since continuous large-amplitude vibration may reduce the effectiveness of the original heat dissipation structure of the ring main unit (such as heat dissipation holes and cooling fans), this airflow can promptly replenish the heat dissipation demand, preventing the primary equipment from experiencing problems such as reduced insulation performance and component damage due to overheating. While ensuring the vibration isolation effect, it further maintains the stable operation of the equipment.
