[0028] The present application provides a technical solution as follows: Figures 1-8The primary and secondary integrated ring network box shown includes a base 1, the base 1 is provided with an outdoor box 2, the base 1 is provided with a pad 4; the pad 4 is sequentially provided with a secondary equipment cabin 6, an operating mechanism cabin 7 and a primary equipment cabin 8 from top to bottom and installed through an integrated frame 5; the top wall of the outdoor box 2 is fixedly provided with a fixed plate 9, the top of the secondary equipment cabin 6 is fixedly provided with a compression-resistant plate 10 corresponding to the fixed plate 9; a plurality of circumferentially distributed air pumping grooves 23 are formed in the fixed plate 9, a leather cup 26 is slidably connected in the air pumping grooves 23, and the bottom of the leather cup 26 is provided with a fixing rod 25; a limiting groove 20 is formed in the fixed plate 9, a limiting rod 28 is inserted into the limiting groove 20, the limiting groove 20 is respectively provided with a first plugging rod 21 and a second plugging rod 22, and an air exhaust groove one 29 and an air exhaust groove two 30 are respectively formed in the limiting rod 28 and correspond to the first plugging rod 21 and the second plugging rod 22; the outdoor box 2 is provided with a plurality of box doors 3, the integrated frame 5 is arranged in the outdoor box 2, and the integrated frame 5 is provided with a plurality of groups arranged side by side; the fixing rod 25 is fixedly connected with the compression-resistant plate 10, the limiting rod 28 is fixedly connected with the compression-resistant plate 10, the limiting rod 28 is arranged at the center of the compression-resistant plate 10, and a plurality of fixing rods 25 are arranged at the edges of the compression-resistant plate 10; a buffer groove 13 is formed in the base 1, a containing groove 14 is formed in the buffer groove 13, an air exhaust pipe 15 is formed in the containing groove 14, and the air exhaust pipe 15 is arranged at the upper portion of the containing groove 14; a retreat rod 11 is arranged at the bottom of the pad 4, the retreat rod 11 is inserted into the buffer groove 13, a buffer spring one 12 is arranged between the pad 4 and the base 1, and the buffer spring one 12 is sleeved on the retreat rod 11; an adjusting rod 16 corresponding to the containing groove 14 is arranged at the bottom of the retreat rod 11, a buffer spring two 17 is arranged between the retreat rod 11 and the bottom wall of the buffer groove 13, and the buffer spring two 17 is sleeved on the adjusting rod 16.

[0029] In the embodiment, the base 1 serves as the basic support structure of the ring network box, the buffer groove 13 and the containing groove 14 formed in the base 1 form a nested cavity structure and are coaxially distributed, thereby providing a space carrier for the realization of the gas damping effect. The retreat rod 11 at the bottom of the pad 4 is in sliding fit with the buffer groove 13, so that the pad 4 can stably move in the vertical direction when vibrating and avoid being stuck due to lateral deviation; the buffer spring one 12 is sleeved on the outside of the retreat rod 11, one end of the buffer spring one 12 abuts against the bottom of the pad 4, and the other end of the buffer spring one 12 is fixed on the upper surface of the base 1, so that the buffer spring one 12 is in a slightly compressed state in the initial state and can directly bear the weight of the pad 4 and the equipment cabin above, and can quickly absorb part of the vibration energy when small-amplitude vibration occurs through elastic deformation.

[0030] The adjusting rod 16 at the bottom of the retreat rod 11 is also in sliding fit with the accommodating groove 14, and the outer diameter thereof is accurately matched with the inner diameter of the accommodating groove 14, so as to ensure the gas sealing property; the buffer spring two 17 is sleeved outside the adjusting rod 16, is connected with the bottom of the retreat rod 11 and the bottom wall of the buffer groove 13, and forms a double-layer elastic support structure with the buffer spring one 12, so that the vibration energy can be further dispersed, and the elastic fatigue caused by the single spring bearing too large load can be avoided. In addition, the exhaust pipe 15 at the upper part of the accommodating groove 14 penetrates through the side wall of the base 1, and the opening direction thereof avoids the inside of the outdoor box 2, so as to prevent the dust or water vapor carried by the exhaust gas from affecting the equipment in the box, and ensure that the air in the buffer groove 13 can be smoothly discharged in small vibration, without additional damping burden.

[0031] The integrated frame 5 is made of light-weight high-strength material, and uniform gaps are reserved between the multiple groups of frames arranged in parallel, so as to facilitate the independent installation and disassembly of each equipment cabin and provide space for the arrangement of subsequent air bag assemblies. The multiple box doors 3 on the outdoor box 2 correspond to the front and side positions respectively, and each box door 3 is provided with a sealing rubber strip and a safety lock, so as to ensure the convenience of operation and maintenance, effectively isolate outdoor rainwater, dust and other impurities, and maintain the stability of the operating environment of the equipment in the box.

[0032] Reference Figures 1-8 The multiple groups of pump gas grooves 23 are connected through the air passage 24, the air passage 24 is annular, and the air passage 24 is arranged at the upper end of the pump gas groove 23; the buffer spring three 27 is arranged between the fixed plate 9 and the pressure-resistant plate 10, the buffer spring three 27 is sleeved on the fixed rod 25, and the length of the second sealing rod 22 is greater than that of the first sealing rod 21; one gas conveying pipe 18 is arranged between each adjacent two fixed plates 9, the gas conveying pipe 18 connects the pump gas grooves 23 in the adjacent two fixed plates 9, the gas conveying pipe 18 is connected with the gas collecting pipe 19 in the middle part, the gas collecting pipe 19 is sequentially provided with the air bag one 31, the air bag two 32 and the air bag three 33 from top to bottom, the air bag one 31, the air bag two 32 and the air bag three 33 are connected through the connecting pipe 34, the bottom of the air bag three 33 is provided with the gas outlet pipe 35, and the gas outlet pipe 35 is connected with the tapping pipe 36; the air bag one 31 is located between two adjacent secondary equipment cabins 6, the air bag two 32 is located between two adjacent operation mechanism cabins 7, the air bag three 33 is located between two adjacent primary equipment cabins 8, and the tapping pipe 36 is connected to the bottom of the two adjacent primary equipment cabins 8.

[0033] In this embodiment, the fixed plate 9 and the compression plate 10 are made of rigid materials, and are arranged in parallel to ensure uniform dispersion of force during vibration transmission. The multiple groups of pumping grooves 23 in the fixed plate 9 are distributed in a circular manner, which can uniformly collect the compressed gas generated when the rubber cup 26 slides, avoiding the problem of uneven inflation of the air bag caused by excessive or insufficient local gas pressure; the annular vent groove 24 is provided at the upper end of the pumping groove 23, which connects all the pumping grooves 23 into a whole gas path, ensuring that the gas can be quickly and smoothly delivered to the gas delivery pipe 18.

[0034] The rubber cup 26 is made of a high-elasticity and wear-resistant sealing material, and its edge is tightly fitted with the inner wall of the pumping groove 23 to form a reliable sealing structure, preventing gas leakage from affecting the inflation efficiency; the fixed rod 25 is rigidly connected to the rubber cup 26 and the compression plate 10 at both ends, ensuring that the vibration of the compression plate 10 can be completely transmitted to the rubber cup 26, driving the rubber cup 26 to slide stably in the pumping groove 23. The buffer spring 27 is sleeved outside the fixed rod 25, and its elastic coefficient is precisely matched to provide a certain supporting force for the compression plate 10 at the initial stage of vibration, reducing the impact of vibration on the cooperation gap between the rubber cup 26 and the pumping groove 23, and quickly driving the compression plate 10 and the rubber cup 26 to reset after the vibration ends, ensuring that the components can work normally during the next vibration.

[0035] The limiting groove 20 is provided at the center of the fixed plate 9, and the sliding cooperation between the limiting rod 28 and the limiting groove 20 can limit the transverse displacement of the compression plate 10, avoiding the rubber cup 26 from being separated from the pumping groove 23 due to transverse shaking. The first blocking rod 21 and the second blocking rod 22 are fixed to the inner wall of the limiting groove 20, and the design of the length difference between the two is the key to realizing damping grading: the shorter first blocking rod 21 corresponds to the damping adjustment of medium amplitude vibration, and the longer second blocking rod 22 corresponds to the damping adjustment of large amplitude vibration, which precisely controls the exhaust speed of the gas in the limiting groove 20 through the cooperation with the exhaust groove on the limiting rod 28, and then realizes the damping change under different vibration scenes.

[0036] The gas delivery pipe 18 is made of a flexible and pressure-resistant material, and its two ends are respectively sealed and connected with the vent grooves 24 in the adjacent fixed plates 9, ensuring that the gas can be smoothly delivered from the pumping groove 23 to the gas collecting pipe 19; the gas collecting pipe 19 serves as the gas distribution hub, and uniformly distributes the gas to the air bag one 31, the air bag two 32, and the air bag three 33. The three air bags correspond to the gap positions of different equipment cabins respectively, the air bag one 31 is adapted to the precision characteristics of the secondary equipment cabin 6, and uses a softer material to reduce rigid impact; the air bag three 33 is adapted to the high-pressure environment of the primary equipment cabin 8, and uses a material resistant to high temperature and aging to ensure safety in use. The connecting pipe 34 connects the three air bags, ensuring that the inflation speeds of the three are synchronized, avoiding uneven stress on the equipment cabin due to different inflation speeds; the port of the tapping pipe 36 is directed towards the heating components inside the primary equipment cabin 8, ensuring that the discharged gas can directly act on the heating area, improving the heat dissipation effect.

[0037] Reference Figures 1-8 , working principle:

[0038] The primary and secondary fusion ring net box realizes accurate response to different amplitude vibrations through the design of "hierarchical damping and air driving linkage", and synchronously completes the functions of vibration isolation and auxiliary heat dissipation. The specific working process is as follows:

[0039] I. Small amplitude vibration response stage:

[0040] When the ring net box is subjected to small amplitude vibration (such as slight transportation bumping, outdoor ground wind disturbance), the vibration energy is first transmitted to the base 1, and then acts on the pad 4. At this time, the buffer spring one 12 and the buffer spring two 17 at the bottom of the pad 4 rapidly compress and deform, absorbing part of the vibration energy through the conversion of elastic potential energy, slowing down the descending speed of the pad 4. At the same time, the pad 4 drives the displacement rod 11 to slide downward along the buffer groove 13, and the air in the buffer groove 13 is extruded and then smoothly discharged through the exhaust pipe 15 at the upper part of the containing groove 14, forming a light gas damping effect, further weakening the remaining vibration energy, and avoiding the direct transmission of vibration to the upper equipment cabin.

[0041] In this process, the compression plate 10 at the top of the secondary equipment cabin 6 only produces small amplitude shaking, driving the limiting rod 28 to slide slightly in the limiting groove 20. Due to the small amplitude of vibration, the sliding distance of the limiting rod 28 is limited, and the first sealing rod 21 and the second sealing rod 22 are not inserted into the corresponding exhaust groove one 29 and the exhaust groove two 30. The gas in the limiting groove 20 can be quickly discharged through the two exhaust grooves, and the overall damping is small, which not only realizes primary buffering, but also avoids unnecessary shaking of the equipment cabin caused by excessive damping, ensuring the stable operation of the precision components in the secondary equipment cabin 6.

[0042] II. Medium amplitude vibration response stage:

[0043] When the vibration amplitude increases (such as moderate impact, ground construction disturbance), the impact force on the pad 4 increases, and the descending amplitude increases. At this time, the compression amount of the buffer spring one 12 and the buffer spring two 17 reaches a large value, and the energy absorption efficiency of elastic deformation gradually decreases. The displacement rod 11 drives the adjusting rod 16 to further insert into the containing groove 14. With the deepening of the adjusting rod 16, its top end eventually blocks the exhaust pipe 15 at the upper part of the containing groove 14, forming a relatively closed cavity between the buffer groove 13 and the containing groove 14.

[0044] The air in the closed cavity cannot be discharged through the exhaust pipe 15, and as the base plate 4 continues to drop, the gas pressure in the cavity continues to rise, generating a reverse support force on the retreat rod 11 and the adjusting rod 16, hindering the continued descent of the base plate 4, and the gas damping effect is significantly upgraded, rapidly weakening the energy of the medium amplitude vibration. At the same time, the shaking amplitude of the pressure-resistant plate 10 increases, driving the limiting rod 28 to slide in the limiting groove 20 to increase the distance, the first blocking rod 21 is inserted into the exhaust groove one 29, blocking the exhaust passage, the gas in the limiting groove 20 can only be discharged through the exhaust groove two 30, the exhaust speed is slowed down, the damping is further increased, effectively limiting the shaking amplitude of the secondary equipment cabin 6, protecting the mechanical parts in the operating mechanism cabin 7 from the influence of severe vibration.

[0045] Three, large amplitude vibration response stage:

[0046] When the vibration amplitude further increases, exceeding the processing capacity of the base plate 1 buffer assembly (such as severe impact, strong earthquake), the vibration energy is directly transmitted to the integrated frame 5, driving the secondary equipment cabin 6, the operating mechanism cabin 7, the primary equipment cabin 8 to produce obvious vibration. At this time, the pressure-resistant plate 10 at the top of the secondary equipment cabin 6 moves up and down synchronously with the equipment cabin, driving the fixed rod 25 to move axially along the air pumping groove 23, and the rubber cup 26 at the top of the fixed rod 25 slides in the air pumping groove 23, like a "pump" principle, compressing the air in the air pumping groove 23.

[0047] The compressed air is collected through the annular air passage 24, transported to the gas collecting pipe 19 through the gas conveying pipe 18, and then distributed to the air bag one 31, the air bag two 32, and the air bag three 33 through the gas collecting pipe 19. Since the three air bags are connected through the connecting pipe 34, the gas is simultaneously filled into the air bags, causing the air bags to rapidly expand and fill the gap between adjacent equipment cabins, forming a flexible isolation layer. The expanded air bags not only block the transmission of vibration between different equipment cabins, preventing the vibration between the secondary equipment cabin 6 and the primary equipment cabin 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.

[0048] In this process, the limiting rod 28 slides to the maximum amplitude in the limiting groove 20, the second blocking rod 22 is inserted into the exhaust groove two 30, both exhaust grooves are blocked, the gas in the limiting groove 20 can only be slowly discharged through the small gap between the limiting rod 28 and the limiting groove 20, the damping reaches the maximum value, the movement of the pressure-resistant plate 10 is maximally limited, and the rubber cup 26 is always stably sliding in the air pumping groove 23, continuously supplying air to the air bag.

[0049] Four, sustained large amplitude vibration response stage:

[0050] If the large amplitude vibration continues to occur, the leather cup 26 will continue to slide in the pumping groove 23, continuously delivering compressed air to the air bag, until the air bag one 31, the air bag two 32, and the air bag three 33 are all filled with gas and cannot continue to expand. At this time, the continuously generated compressed air in the pumping groove 23 has no place to accommodate, and will enter the tapping pipe 36 through the air outlet pipe 35 at the bottom of the air bag three 33, and then be discharged into the adjacent primary equipment cabin 8 through the port of the tapping pipe 36.

[0051] The gas entering the primary equipment cabin 8 forms a flowing gas stream, which can carry away the heat generated by the high-voltage equipment during operation. Since the sustained large amplitude vibration can cause the effectiveness of the original heat dissipation structure (such as heat dissipation holes and heat dissipation fans) of the ring network box to decrease, the gas stream can timely supplement the heat dissipation demand, avoid problems such as insulation performance degradation and component damage of the primary equipment due to overheating, and further maintain the stable operation state of the equipment while ensuring the vibration isolation effect.
