Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to an intelligent primary and secondary integrated ring main unit. Background Technology

[0002] With the continuous development of smart grids, intelligent primary and secondary integrated ring network boxes, as key equipment in distribution network automation systems, are widely used in urban power grid transformation and distribution nodes.

[0003] One related technology involves a primary and secondary integrated ring main unit, comprising a cabinet with a receiving groove on the front. The receiving groove houses high-voltage electrical components and secondary control equipment. A cabinet door is rotatably connected within the receiving groove, and a rubber sealing strip is installed between the cabinet door and the inner wall of the receiving groove.

[0004] In recent years, some regions have frequently suffered from floods, causing ring main units to be submerged in deep water, posing a severe challenge to traditional passive rubber sealing strips. In deep water, the hydrostatic pressure outside the unit increases dramatically, compounded by the impact of the water flow. This high-intensity water pressure continuously squeezes the sealing strip inward. Due to the limited elasticity of the rubber sealing strip and the inevitable presence of tiny gaps at the joint surface, under the immense external water pressure, the water flow easily overcomes the physical resistance of the sealing strip, instantly breaching the seal between the door and the threshold. A large amount of water rushes into the ring main unit's containment chamber through these gaps, causing severe short circuits or even complete damage to the expensive high-voltage electrical components and secondary control equipment inside, leading to widespread power outages at distribution network nodes. Summary of the Invention

[0005] To address the problem that existing ring main units, when subjected to deep water flooding, suffer from the inability of traditional passive sealing structures to withstand high external water pressure, allowing water to easily seep into the interior through the gaps in the door, thus causing equipment damage, this application provides an intelligent primary and secondary integrated ring main unit.

[0006] This application provides an intelligent primary and secondary integrated ring network box, which adopts the following technical solution: An intelligent primary and secondary integrated ring network box includes a box body. A receiving groove is formed on the front of the box body, and a box door is rotatably connected within the receiving groove. A sealing module is disposed inside the box body. The sealing module includes a door barrier structure disposed within the receiving groove and an inflation structure disposed on the box body. A storage ring groove is formed on the side of the door barrier structure facing the box door. An airbag and an air inlet connector communicating with the airbag are disposed within the storage ring groove. The inflation structure is used to inflate the airbag. The inflation structure includes a storage box and a water filling component disposed within the box body. The storage box contains… The container has a reaction chamber, a first storage chamber for storing acid, and a second storage chamber for storing bicarbonate / carbonate. Both the first and second storage chambers are separated from the reaction chamber by a water-soluble diaphragm. The storage box is equipped with a one-way air inlet valve that communicates with the reaction chamber. The door structure has an air inlet hole that connects the air inlet connector to the one-way air inlet valve. A water filling assembly is used to add water into the reaction chamber so that the bicarbonate / carbonate reacts with the acid to produce carbon dioxide gas. The produced carbon dioxide gas fills the air bladder, causing the air bladder to expand and press against the door of the container.

[0007] By adopting the above technical solution, and by pre-installing an expandable airbag in the storage ring groove of the gate structure, and introducing an inflation structure based on chemical reaction, when the ring network box encounters the danger of flooding, water can be added to the reaction chamber through the water addition component, directly triggering a rapid reaction between the acid and bicarbonate or carbonate. The large amount of gas generated at the moment of reaction is quickly filled into the airbag through the one-way air inlet valve, causing the airbag to expand powerfully and tightly fill the gap between the inner wall of the storage groove and the box door. This resists the high-pressure flooding caused by external floods, reduces the probability of water entering the box, lowers the risk of failure of electrical equipment inside the box, and improves the absolute reliability of the overall seal.

[0008] Optionally, the gate structure includes a fixing strip fixedly connected to the inner wall of the receiving groove. The inner wall of the receiving groove in contact with the fixing strip is provided with a long groove-shaped fixing groove. The length direction of the fixing groove is consistent with the axial direction of the receiving groove. The storage box is slidably disposed in the fixing groove. A slide rail is provided on the side of the fixing strip away from the axis of the receiving groove for a one-way air intake valve to slide into. The outlet of the air intake port on the side away from the air intake connector extends to the bottom wall of the slide rail. When the air intake port is connected to the one-way air intake valve, the one-way air intake valve is in contact with the bottom wall of the slide rail.

[0009] By adopting the above technical solution, the storage box can be conveniently installed in the box by sliding and plugging, which greatly simplifies the replacement and assembly of reaction consumables in the later operation and maintenance. During the process of the storage box sliding into place, the one-way air inlet valve can accurately guide the gas along the slide and fit against the bottom wall of the slide, and finally realize the rapid alignment of the gas outlet on the reaction chamber side and the air inlet channel on the door structure side. This not only eliminates the cumbersome manual connection steps and improves the assembly efficiency, but also ensures that the high-pressure carbon dioxide gas generated by the reaction can be accurately introduced into the air bag without leakage, effectively ensuring the airtightness of the airflow conduction and the reliability of the system response.

[0010] Optionally, a baffle for blocking the air inlet is slidably disposed in the slide rail, and a long groove is opened on both inner walls of the slide rail along the length of the fixed strip. A slider is slidably disposed in the groove at both ends of the baffle along the length of the fixed strip.

[0011] By adopting the above technical solution, a sliding baffle with a slider is added inside the slide, and in conjunction with the long strip-shaped grooves on both sides of the slide, precise sealing and protection of the air inlet is achieved. When not assembled or during routine replacement of the storage box, the baffle can reliably seal the air inlet, effectively preventing external moisture, dust, and impurities from entering the airbag and airway system, ensuring the long-term cleanliness and sealing safety of the internal airway. At the same time, the limiting and guiding cooperation between the slider and the groove not only restricts the movement trajectory of the baffle, preventing it from shifting or falling off under force, but also makes the sliding opening and closing process of the baffle more stable and smooth, avoiding mechanical jamming, and significantly improving the structural stability and operational smoothness of this local component.

[0012] Optionally, an iron sheet is provided on the inner wall of the baffle facing the bottom wall of the receiving groove, and a magnet that can magnetically engage with the iron sheet is provided on the end face of the one-way air inlet valve away from the bottom wall of the receiving groove.

[0013] By adopting the above technical solution and setting up iron plates and magnets, a non-contact magnetic positioning and locking mechanism is cleverly introduced. When the storage box slides into the predetermined working position along the fixed groove, the magnet on the one-way air intake valve and the iron plate in the slide automatically and accurately engage. This not only provides maintenance personnel with clear "plug-in" tactile feedback in operating environments where visibility is obstructed or space is confined, ensuring perfect alignment between the one-way air intake valve and the air intake hole, but more importantly, the magnetic attraction force can effectively resist the mechanical vibration generated by the ring network box during long-term outdoor operation or when it encounters flood impact, preventing the storage box from undergoing slight displacement or accidental loosening. This ensures the absolute sealing of the air circuit connection part in emergency inflation mode and eliminates the risk of leakage of high-pressure carbon dioxide gas.

[0014] Optionally, the housing has an installation cavity located on the side of the receiving groove, and the inner wall of the installation cavity away from the receiving groove has an installation hole. The water filling assembly includes a water storage box disposed in the installation cavity, and a water inlet pipe is disposed at the upper end of the water storage box. The water inlet pipe extends away from the receiving groove and is inserted into the installation hole. The housing has a fixing hole connecting the installation cavity and the fixing groove. The side of the water storage box is provided with a water outlet pipe that can communicate with the reaction chamber, and the water outlet pipe is disposed in the fixing hole.

[0015] By adopting the above technical solution, an installation cavity is set on the side of the receiving tank, and a water storage box is arranged in the installation cavity, so that the water supply component forms an independent water collection and supply unit. When the external flood is higher than the installation hole, water can enter through the installation hole and flow into the water storage box through the water inlet pipe, providing sufficient water reserves for subsequent chemical reaction. The water storage box plays the role of buffering, collecting and stabilizing water supply. Then, the water is directed into the reaction chamber through the water outlet pipe, and the reaction chamber can obtain a continuous and controllable water supply to trigger the reaction of acid with bicarbonate or carbonate to produce gas. At the same time, this layout design, which physically isolates the core electrical equipment in the receiving tank from the water storage box, not only effectively prevents the water from rain, washing or splashing water from accidentally entering the water storage system and causing the gasbag to expand accidentally, but also fundamentally eliminates the secondary damage to the high voltage insulation performance inside the box caused by possible leakage of the water storage component itself, greatly improving the standby safety and working reliability of the entire pure mechanical water supply system in complex outdoor environments.

[0016] Optionally, the water outlet pipe includes a first water outlet pipe communicating with the water storage box. A telescopic folding pipe is provided on the side of the first water outlet pipe away from the water storage box. A second water outlet pipe is provided on the side of the telescopic folding pipe away from the first water outlet pipe. A spring is sleeved on the telescopic folding pipe and located between the first water outlet pipe and the second water outlet pipe. One end of the spring abuts against the first water outlet pipe, and the other end of the spring abuts against the second water outlet pipe. A solenoid valve is provided on the first water outlet pipe. A feed hole communicating with the reaction chamber and communicating with the second water outlet pipe is opened on the side of the storage box.

[0017] By adopting the above technical solution, an adaptive flexible docking water circuit with elastic compensation function is cleverly constructed by introducing a telescopic folding pipe between the first and second water outlet pipes and externally sleeved with a retaining spring. When the storage box is pushed into the assembly station, the spring is compressed to generate a continuous elastic pre-tightening force, forcing the end of the second water outlet pipe to fit tightly with the feed hole and maintain a dynamic pressing state. This completes the automatic sealing docking of the blind-insertion water circuit between the water supply component and the reaction chamber, which not only eliminates the cumbersome manual pipe connection operation, but also effectively absorbs the vibration displacement and machining tolerance during equipment operation, and eliminates the risk of water leakage during the water intake process. At the same time, a solenoid valve is installed on the first water outlet pipe, so that the water supply to the reaction chamber has controllable opening and closing capability. It can open the water supply when gas generation needs to be triggered and close the isolation in the non-triggered state, ensuring that the water volume is released instantaneously to trigger the chemical reaction only when the system determines that the flood warning condition has been reached, which greatly improves the accuracy and controllability of the disaster prevention triggering mechanism.

[0018] Optionally, the feed hole allows the second water outlet pipe to be inserted and sealed with the second water outlet pipe. The feed hole is provided with a protective membrane that can be punctured by the second water outlet pipe. The protective membrane is used to seal the feed hole when the second water outlet pipe is not inserted.

[0019] By adopting the above technical solution and setting a protective membrane, the feed hole is reliably sealed when not assembled and connected, thereby preventing external moisture, dust, or foreign objects from entering the reaction chamber through the feed hole, and avoiding the acid and bicarbonate or carbonate from becoming damp and clumping, and reacting prematurely. When the second water outlet pipe is inserted, the protective membrane is automatically punctured and forms a passage, eliminating the tedious step of manually tearing the membrane in advance. At the same time, the sealing cooperation reduces the risk of water leakage and seepage during the water addition process, ensuring that the water flow can be directed and effectively introduced into the reaction chamber to stably trigger the gas generation process. More importantly, after the second water outlet pipe is deeply inserted into the feed hole, its pipe body is embedded in the hole like a pin. Combined with the pre-tightening force of the external spring, it forms a direct and reliable mechanical lock and limit on the sliding assembly storage box, effectively resisting the risk of accidental displacement and slippage of the storage box that may be caused by the impact of external floods or vibrations during long-term operation of the equipment, and ensuring the structural stability and operational reliability of the emergency gas filling system under extreme flood conditions.

[0020] Optionally, the housing is provided with a detection structure, and the front of the housing is provided with a groove located below the door. The detection structure includes a pressure sensor disposed in the groove and a controller electrically connected to the pressure sensor. The controller is used to control the opening and closing of the solenoid valve.

[0021] By adopting the above technical solution, when floods occur, the low-level sensor can immediately and in real time obtain the changes in the constantly rising static water pressure. Based on the electrical signal interaction between the pressure sensor and the controller, the opening and closing of the solenoid valve is controlled, thereby realizing the automatic judgment and precise control of the water addition triggering process of the reaction chamber. This effectively eliminates the risk of false triggering caused by daily rainstorms or splashing water from vehicles, and achieves efficient, accurate and controllable disaster prevention actions.

[0022] Optionally, the housing is provided with an energy storage element for electrical connection to the solenoid valve and the controller respectively, and the top of the housing is provided with a solar panel for electrical connection to the energy storage element.

[0023] By adopting the above technical solutions, in severe situations such as large-scale power outages or proactive load shedding during floods, the emergency gas-filled defense system can completely eliminate its dependence on external mains power through energy storage components. The energy storage components can still provide the necessary operating power to the controller and solenoid valves, ensuring the continuous execution of pressure signal-based judgments and solenoid valve opening and closing controls. This enhances the practical reliability and emergency survivability of the ring network box in the entire intelligent flood control system. Solar panels can replenish the energy storage components during normal operation, achieving energy-saving and power-saving effects.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By pre-installing an inflatable airbag in the storage ring groove of the gate structure and introducing a chemical reaction-based inflation component, when the ring network box encounters the danger of flooding, water can be added to the reaction chamber through the water addition component, directly triggering a rapid reaction between the acid and bicarbonate or carbonate. The large amount of gas generated at the moment of reaction is quickly filled into the airbag through the one-way air inlet valve, causing the airbag to expand powerfully and tightly fill the gap between the inner wall of the storage groove and the box door, resisting the high-pressure flooding formed by external floods, reducing the probability of water entering the box, reducing the risk of failure of electrical equipment inside the box, and improving the absolute reliability of the overall seal. By adopting a sliding plug-in storage box combined with flexible water channels and magnetic air channels to achieve blind plug-in docking and mechanical self-locking, it not only greatly simplifies the daily operation and maintenance of flood control consumables and ensures the long-term moisture protection of the agents, but also, combined with low-position pressure sensors and off-grid energy storage systems, enables accurate identification and automatic triggering of flood risks under extreme conditions such as power outages, comprehensively improving the response capability and long-term standby reliability of the sealing module.

An operating box 223 is disposed in the operating slot and is used to filter and collect rainwater. In other embodiments, the operating box 223 is connected to the mounting box via a pipe, so that water in the operating box 223 can be transported into the mounting box.

[0053] Reference Figure 1 and Figure 6The inner wall of the operating trough is provided with a first operating hole and a second operating hole. The first operating hole connects the fixing groove 107 located on the inner wall of the receiving trough 101 to the operating trough. A first pipe is provided in the first operating hole. The structure of the first pipe is the same as that of the water outlet pipe 222, except that the first pipe is used to transport water in the operating box 223 to the storage box 212 above the receiving trough 101.

[0054] Similarly, the second operating hole connects the fixing groove 107 located on the inner wall of the receiving groove 101 with the operating groove. A second pipe is provided in the second operating hole. The structure of the second pipe is the same as that of the water outlet pipe 222, except that the second pipe is used to transport water in the operating box 223 to the storage box 212 above the receiving groove 101.

[0055] Reference Figure 8 The enclosure 100 is equipped with a detection structure 300 for disaster prevention detection. A recess 111 is provided on the front of the enclosure 100, located directly below the door 102. The detection structure 300 includes a pressure sensor 301 and a controller 302.

[0056] Reference Figure 7 and Figure 8 Both pressure sensor 301 and controller 302 are housed within recess 111. Pressure sensor 301 and solenoid valve 229 are electrically connected to controller 302. Controller 302 controls the opening and closing of all solenoid valves 229. Controller 302 can preset a flood warning threshold. When pressure sensor 301 detects that external water pressure reaches or exceeds the flood warning threshold, controller 302 outputs a drive signal to open solenoid valve 229, allowing water from storage box 220 to enter reaction chamber 216 via outlet pipe 222. When external water pressure falls below the flood warning threshold or the danger is averted, controller 302 controls solenoid valve 229 to close, stopping water supply and reducing ineffective reaction consumption.

[0057] Optionally, the controller 302 can be set with a delay strategy and a hysteresis range to prevent water pressure fluctuations from causing the solenoid valve 229 to open and close frequently.

[0058] Reference Figure 3 and Figure 8 An energy storage element 112 is fixedly connected to the upper inner wall of the receiving tank 101. The solenoid valve 229, pressure sensor 301, and controller 302 are all electrically connected to the energy storage element 112. The energy storage element 112 can be a lithium battery, a lithium iron phosphate battery, or a supercapacitor. A solar panel 113 is fixedly connected to the top of the housing 100, and the solar panel 113 is electrically connected to the energy storage element 112.

[0059] The implementation principle of an intelligent primary and secondary integrated ring network box according to this application embodiment is as follows: When a flood inundation occurs, external water enters the inlet pipe 221 through the installation hole 109 and flows into the water storage box 220. After the pressure sensor 301 detects that the external water pressure has reached the flood warning threshold, the controller 302 controls the solenoid valve 229 to open, so that the water in the water storage box 220 and the water in the operation box 223 are respectively input into the corresponding storage box 212, so that the acid in the storage box 212 reacts rapidly with bicarbonate or carbonate in the reaction chamber 216 to generate carbon dioxide. The generated high-pressure carbon dioxide gas opens the one-way air inlet valve 213 and is output into the air bag 202 through the air inlet hole 208 and air inlet connector 203. The air bag 202 expands instantly and fills the gap of the box door 102, successfully blocking the external flood inundation.
