A smart relay station integrating electricity storage, charging and electricity conversion

Abstract

This invention provides a smart rest station integrating energy storage, charging, and electrical energy conversion, relating to the field of urban rest station technology. This smart rest station, integrating energy storage, charging, and electrical energy conversion, includes a rest area. By setting up a rainwater collection pool, it collects and stores rainwater during the rainy season, effectively saving water resources. Once smoke is detected due to battery malfunction, a hydraulic cylinder extends and retracts its shaft, immersing the battery pack under the vehicle in the water pool for cooling. Rainwater is continuously replenished from the collection pool through a water supply pipe to maintain cooling, minimizing the risk of battery malfunction and fire. The retraction of two sets of cylinders causes the insertion rod to separate from the counterweight ring. The counterweight ring falls under its own weight, causing the fireproof sleeve to unfold and fit onto the movable plate, collecting all the smoke inside the fireproof sleeve. Water mist is then sprayed through a water spray pipe to cool the smoke, which is then extracted through a smoke extraction pipe by a fan. During extraction, the smoke is thoroughly disinfected and filtered through a first and second disinfection filter box.

Description

Technical Field

[0001] This invention relates to the field of urban rest station technology, specifically a smart rest station that integrates energy storage, charging, and energy conversion. Background Technology

[0002] "Photovoltaic power generation + energy storage system + power conversion" are the three common functions of an integrated photovoltaic-storage-charging project. In the market, some public projects have added "photovoltaic-storage-charging" functions to traditional charging station facilities, as well as multiple functions such as battery testing and living services, to become a comprehensive and multifunctional "smart station". This means that the traditional charging station has achieved industrial upgrading. It includes elements such as photovoltaic, energy storage, charging and discharging, and grid power introduction, namely power generation, energy storage, charging and discharging. It can also produce green and clean energy, guide the reduction of carbon emissions, and introduce municipal grid electricity to charge at night and discharge during the day to meet the comprehensive electricity needs of citizens, with multiple values ​​including social, economic and ecological benefits.

[0003] However, all existing and under-construction smart stations that provide living services and integrate energy storage, charging, and energy conversion have a significant safety hazard: new energy vehicles charging at these stations may experience battery runaway and fires during the charging process. The charging process and the stationary state after full charge are the main components of these fires. A battery safety research report from a domestic university's battery safety laboratory shows that, in the collected cases, fires caused by new energy vehicles being stationary or charging accounted for 58% of all incidents, significantly higher than the 26% rate of fires while in motion. Furthermore, based on the collected cases of fires caused by new energy vehicles being stationary or charging, these incidents all resulted in varying degrees of damage to surrounding vehicles and facilities. Currently, new energy vehicle power battery fires cannot be effectively extinguished; the only recourse is to continuously cool them down with water until the battery is completely burned. In conclusion, when developing smart stations that integrate energy storage, charging, and energy conversion, measures should be in place to address accidents caused by power battery fires resulting from the idling and charging of new energy vehicles.

[0015] (III) Beneficial Effects This invention provides a smart station that integrates energy storage, charging, and electrical energy conversion. It has the following beneficial effects: 1. Compared with existing technologies, this smart station, which integrates energy storage, charging and energy conversion, collects and stores rainwater during the rainy season by setting up a rainwater collection pool. This water is used for daily water use in the multi-functional room and also to deal with the large amount of water used in case of fire when vehicles are parked or charging in the parking unit, thus effectively saving water resources.

[0016] 2. Compared with existing technologies, this smart station, which integrates energy storage, charging, and energy conversion, has parking spaces located above a movable platform. A smoke detector monitors the safety of vehicles during parking and charging. If smoke is detected due to battery malfunction, a hydraulic cylinder extends and retracts, causing the movable platform and vehicle to sink into a water tank. The battery pack under the vehicle is then immersed in the water for cooling. Rainwater is continuously replenished from a rainwater collection tank via a water supply pipe to maintain cooling, minimizing the risk of battery fire. The water after heat exchange is collected in a sewage treatment pond through a drainage pipe, preventing rainwater from coming into contact with harmful substances produced during battery combustion and flowing into the ground, thus avoiding pollution of local water sources.

[0017] 3. Compared with existing technologies, this smart rest station, which integrates energy storage, charging, and energy conversion, takes measures to prevent harmful fumes from the combustion of power batteries from threatening the health of people in the rest area. Simultaneously, the battery pack at the bottom of the vehicle is immersed in a water pool for cooling, while the two sets of cylinder extension shafts retract, causing the insertion rod to separate from the counterweight ring. The counterweight ring falls under its own weight, causing the fireproof sleeve to unfold and fit onto the movable plate, collecting all the smoke inside the fireproof sleeve. Water mist is then sprayed through a water spray pipe to cool the smoke, which is then extracted through a smoke extraction pipe by a fan. During extraction, the smoke is thoroughly disinfected and filtered through the first and second disinfection filter boxes, improving the air safety of the rest area. Attached Figure Description

[0020] 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.

[0021] Example: Figures 1 to 6 As shown, this embodiment of the invention provides a smart station integrating energy storage, charging, and power conversion. It includes a station area 1, which comprises a multi-functional room 2, a hydraulic system, an energy storage device, a municipal power grid, a sewage treatment pond, two sets of rainwater collection ponds, two sets of parking areas, and two sets of water pumps. The multi-functional room 2 is located in the center of the station area 1, with the two parking areas located on the left and right sides of the multi-functional room 2, and the two rainwater collection ponds located on the side of the two parking areas furthest from the multi-functional room 2. A basement is located below the multi-functional room 2, and the energy storage device is located inside the basement. The multi-functional room 2 houses the station, adding "photovoltaic-energy storage-charging" functionality. It can also add other living services and other functions, becoming a comprehensive and multi-functional "smart station." This achieves an industrial upgrade of traditional stations, encompassing elements such as photovoltaic-energy storage-charging-discharging and municipal power introduction, i.e., power generation, energy storage, charging, and discharging. It can also produce green and clean energy, guiding the reduction of carbon emissions, while introducing municipal power for charging at night with low-cost electricity and discharging during the day to meet the comprehensive electricity needs of citizens, possessing multiple values ​​including social, economic, and ecological benefits. like Figure 1 As shown, the rainwater collection tank is equipped with multiple rainwater collection modules 4 for filtering and collecting rainwater. The rainwater collection module 4 is a common rainwater collection device on the market, which can be either PP module or carbon fiber module. By collecting and filtering rainwater during the rainy season and storing it for later use, it can provide domestic water for the multi-functional room 2, and can also provide a large amount of fire-fighting and cooling water for new energy vehicles in the event of a fire, thus playing a role in saving water resources. like Figure 1 , Figure 2 As shown, in order to realize the functions of energy storage, charging and power conversion, the parking area consists of multiple rectangular parking units. Each parking unit consists of a water tank 5, a car charging device and a canopy 10. The multi-functional room 2 and the top of the canopy 10 are respectively equipped with a first photovoltaic panel 3 and a second photovoltaic panel 11. The energy storage device is electrically connected to the first photovoltaic panel 3, the second photovoltaic panel 11, the multi-functional room 2, the municipal power grid and the car charging device through a charging and discharging protection circuit. The car charging device includes a fixed base 6 and a charging pile 8. The fixed base 6 is fixedly connected to the ground of the parking area and located behind the water tank 5. The charging pile 8 is fixedly connected to the upper wall of the fixed base 6 through a column 7. The charging pile 8 can charge vehicles. The first photovoltaic panel 3 and the second photovoltaic panel 11 can charge the energy storage device. When the municipal power grid is connected to the energy storage device, it can be charged at night with low-priced electricity. During the day, when the electricity price is high, it can provide nighttime charging electricity to the surrounding residents. like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the water tank 5 is located below the ground level of the parking area, with its upper surface flush with the ground. The interior of the water tank 5 is connected to the rainwater collection tank via a water supply pipe 20 and a water pump. The bottom of the water tank 5 is connected to the sewage treatment tank via a drainage pipe 21 and a water pump. A movable plate 12 is slidably connected inside the water tank 5. A lifting drive structure for raising and lowering the movable plate 12 is provided on the lower inner wall of the water tank 5. A parking space 13 is located on the upper wall of the movable plate 12 at its center. A wheel limit rod 14 is fixedly connected to the upper wall of the parking space 13 near the rear end of the movable plate 12. Multiple sets of vertically penetrating water holes 22 are provided on the inner wall of the movable plate 12, located around the parking space 13. The lifting drive structure includes six sets of hydraulic cylinders 19. All six sets of hydraulic cylinders 19 are fixedly connected to the lower inner wall of the water tank 5, arranged in pairs of three near the front and rear inner walls of the water tank 5. The extension shaft ends of all six sets of hydraulic cylinders 19 are fixedly connected to the lower wall of the movable plate 12. The outer walls are all insulated with waterproof and heat-insulating cotton. The inner upper wall of the canopy 10 and the inner and outer sides of the seat ring 29 are provided with heat insulation layer 32. A smoke alarm 33 for detecting smoke is installed in the center of the inner upper wall of the canopy 10. The smoke alarm 33 is used to detect smoke generated by battery fire. When smoke is detected, the hydraulic cylinder 19 is activated. The extension shaft of the hydraulic cylinder 19 retracts, which drives the movable plate 12 to sink. The vehicle parked on the movable plate 12 follows to sink until the battery module at the bottom of the vehicle is immersed in the water in the water tank 5. The water in the water tank 5 quickly cools the power battery. At the same time, a large amount of rainwater is drawn from the rainwater collection tank through the water pump, i.e. the water supply pipe 20, to continuously cool the power battery. The heated water is pumped to the sewage treatment tank through another set of water pumps along the drain pipe 21 to prevent sewage from flowing out and causing local water pollution. The power battery is completely immersed in water to cool down, which can effectively control the fire and prevent damage to other vehicles and surrounding facilities. like Figure 5 As shown, in order to smoothly lower the fireproof sleeve 30 in the event of a fire, the canopy 10 is fixedly connected to the upper side of the water tank 5 by four sets of support columns 9. The inner wall of the canopy 10 is fitted with a counterweight ring 25, which is rectangular in plan view, through a telescopic structure. The telescopic structure includes two sets of cylinders 26, push plates 27, and multiple sets of insert rods 28. The two sets of cylinders 26 are fixedly connected to the inner front wall and inner rear wall of the canopy 10, respectively. The two sets of push plates 27 are fixedly connected to the extension shaft ends of the two sets of cylinders 26, respectively. The insertion rods 28 are fixedly connected to the opposite sides of the two sets of push plates 27 respectively. The ends of the multiple sets of insertion rods 28 away from the push plates 27 pass through the front and rear walls of the counterweight ring 25 respectively and are slidably connected to the counterweight ring 25. The push plates 27 are slidably connected to the side wall of the ceiling 10 through two sets of guide rods 23. After the smoke alarm 33 is triggered, the cylinder 26 extends and retracts, driving the push plates 27 and insertion rods 28 to retract. The insertion rods 28 are separated from the counterweight ring 25, and the counterweight ring 25 falls onto the upper wall of the movable plate 12 by its own weight. like Figure 5 , Figure 6 As shown, in order to prevent the power battery from affecting surrounding vehicles and facilities in the event of a fire, a seat ring 29 is provided on the upper inner wall of the canopy 10, which is vertically opposite to the counterweight ring 25. A protective cover structure for covering the upper part of the movable plate 12 is provided between the counterweight ring 25 and the seat ring 29. The protective cover structure is a fireproof sleeve 30, which is fixedly connected between the counterweight ring 25 and the seat ring 29. The fireproof sleeve 30 is a ring-shaped cloth sleeve with openings at both the top and bottom, and the cloth sleeve is made of fireproof cloth. The unfolded length of the fireproof sleeve 30 is greater than the distance between the canopy 10 and the lower inner wall of the water tank 5. After the counterweight ring 25 falls, it drives the fireproof sleeve 30 to completely cover the vehicle, so that the generated smoke and flames will not be exposed, thus improving safety. like Figure 5 As shown, in order to reduce the internal temperature of the fireproof sleeve 30 and improve the service life of the fireproof sleeve 30 and the smoke filter structure, a water spray cooling structure is provided on the inner upper wall of the canopy 10 and inside the seat ring 29. The water spray cooling structure is a water spray pipe 24, which is located on the inner upper wall of the canopy 10 and inside the seat ring 29. The water spray pipe 24 is made of fire-resistant material. Multiple sets of water spray nozzles 31 are provided on the lower wall of the water spray pipe 24. The water spray pipe 24 is connected to the water supply pipe 20 through a pipe. When the water pump draws water from the rainwater collection pool to replenish the water pool 5, it also sends water to the water spray pipe 24. Water is sprayed into the fireproof sleeve 30 through the water spray nozzles 31 to cool it down, improve the cooling effect, and at the same time cool down the smoke generated when the power battery is burning and settle large particulate matter. like Figure 2 , Figure 5As shown, in order to treat the smoke generated during the combustion of the power battery, a smoke filtration structure is provided on the rear wall of the ceiling 10. The smoke filtration structure includes a smoke extraction pipe 15, a first disinfection filter box 16, a second disinfection filter box 17, and a fan 18. The first disinfection filter box 16 is fixedly connected to the lower wall of the ceiling 10 and is located near the rear wall. The smoke extraction pipe 15 is fixedly connected between the seat ring 29 and the first disinfection filter box 16, and the seat ring 29 and the first disinfection filter box 16 are connected through the smoke extraction pipe 15. The second disinfection filter box 17 is fixedly connected to the lower wall of the first disinfection filter box 16, and the inlet of the second disinfection filter box 17 is... The outlet end of the first disinfection filter box 16 is open, and the fan 18 is fixedly connected to the rear wall of the second disinfection filter box 17. The fan 18 is open to the outlet end of the second disinfection filter box 17. The first disinfection filter box 16 and the second disinfection filter box 17 are respectively provided with an alkaline filter layer and an activated carbon filter layer. The smoke generated by the combustion of the power battery is collected inside the fireproof sleeve 30. The smoke is drawn from the fireproof sleeve 30 through the smoke extraction pipe 15 by the fan 18. During the extraction process, the smoke is fully disinfected and filtered by the first disinfection filter box 16 and the second disinfection filter box 17 before being discharged into the air to avoid harmful smoke from affecting the personnel in the rest area 1.

[0022] Working principle: This smart rest station, integrating energy storage, charging, and power conversion, adds "photovoltaic-energy storage-charging" functions to the traditional public toilet service functions. It can also add other life services and other functions, becoming a comprehensive and multifunctional "smart rest station." It realizes the industrial upgrade of traditional rest stations and includes elements such as photovoltaic-energy storage-charging-discharging and grid power introduction, namely power generation, energy storage, charging, and discharging. It can also produce green and clean energy, guide the reduction of carbon emissions, and introduce municipal grid power to charge at night with low-cost electricity and discharge during the day to meet the comprehensive electricity needs of citizens, thus possessing multiple values ​​in terms of society, economy, and ecology. Meanwhile, to address the risk of battery fires in new energy vehicles, the rainwater collection tank is equipped with multiple rainwater collection modules 4 for filtering and collecting rainwater. These modules are common rainwater collection devices available on the market, and can be either PP or carbon fiber modules. By collecting and filtering rainwater during the rainy season and storing it for later use, it can provide domestic water for the multi-functional room 2, and also provide a large amount of water for firefighting and cooling in the event of a fire in a new energy vehicle, thus conserving water resources. A basement is located below the multi-functional room 2, and the energy storage device is housed inside. The multi-functional room 2 includes living service areas such as rest areas, dining areas, and rest stops. Combined with the "photovoltaic-storage-charging" function, it becomes a facility integrating energy storage, charging, and... This smart station integrates electricity conversion. Charging pile 8 can charge vehicles, while the first photovoltaic panel 3 and the second photovoltaic panel 11 can charge energy storage devices. When connected to the municipal power grid, the energy storage devices can be charged at night using low-priced electricity, and during the day when electricity prices are high, electricity can be provided to nearby residents for nighttime charging. A smoke detector 33 detects smoke from a battery fire. Upon detection, hydraulic cylinder 19 is activated, extending and retracting its shaft to lower the movable plate 12. Vehicles parked on the movable plate 12 follow, sinking until the battery module at the bottom of the vehicle is submerged in water in the pool 5. The water in the pool 5 rapidly cools the power battery, and simultaneously, a water pump... The water supply pipe 20 draws a large amount of rainwater from the rainwater collection tank to continuously cool the power battery. The heated water is then pumped through another water pump along the drain pipe 21 to the sewage treatment tank, preventing sewage from flowing out and polluting the local water source. Completely immersing the power battery in water for cooling effectively controls the fire and prevents damage to other vehicles and surrounding facilities. After the smoke alarm 33 is triggered, the cylinder 26 extends and retracts, causing the push plate 27 and the insert rod 28 to retract. The insert rod 28 separates from the counterweight ring 25, which falls onto the upper wall of the movable plate 12 under its own weight. After the counterweight ring 25 falls, it causes the fireproof sleeve 30 to completely cover the vehicle, preventing smoke and flames from escaping and improving safety. The water pump draws a large amount of rainwater from the rainwater collection tank. When water is pumped from the pool to replenish the pool 5, water is also sent to the spray pipe 24 and sprayed into the fireproof sleeve 30 through the spray nozzle 31 to cool it down and improve the cooling effect. At the same time, it cools down the smoke generated when the power battery is burning and settles large particulate matter. The first disinfection filter box 16 and the second disinfection filter box 17 are respectively equipped with an alkaline filter layer and an activated carbon filter layer. The smoke generated by the power battery combustion gathers inside the fireproof sleeve 30 and is drawn out from the fireproof sleeve 30 by the fan 18 through the smoke extraction pipe 15. During the extraction process, the smoke is fully disinfected and filtered by the first disinfection filter box 16 and the second disinfection filter box 17 before being discharged into the air to avoid harmful smoke from affecting the personnel in the rest area 1.
