Description

Technical Field

[0001] The invention belongs to the technical field of mobile charging and storage equipment, and in particular relates to a mobile integrated charging and storage device. Background Art

[0002] With the rapid development of various emerging industries such as rural homestays, the promotion of new energy construction and the promotion of electric vehicles to the countryside, the volatility and randomness of the distribution network load are becoming increasingly significant. The problems brought by new power systems such as short-term heavy overload, user low-power charging tension, photovoltaic backflow, etc. are becoming more and more prominent. If a comprehensive large-scale power grid transformation is carried out, the investment will be huge. The mobile charging and storage integrated device can achieve flexible transfer, and the multi-functional all-in-one device can solve the problems of low voltage, overload, charging, photovoltaic absorption, emergency power supply and emergency lighting. It is suitable for electric vehicle gathering places (such as: highway service areas, scenic spots), outdoor operations, emergency rescue and other scenes.

[0003] The existing mobile integrated charging and storage device is mainly composed of a cabinet, a temperature control system (compressor cooling), an energy storage inverter, a fire extinguishing system and a mobile component. Among them, the energy storage inverter is used to store and release electric energy, the temperature control system is used to regulate the temperature inside the cabinet and the energy storage inverter, and the fire extinguishing system can prevent fires caused by factors such as poor heat dissipation efficiency, aging of components, and short circuits in the energy storage inverter. The existing mobile integrated charging and storage device still has the following problems during use:

[0004] 1. The existing device mainly relies on the temperature control system to drive the gas circulation flow to cool the energy storage converter. Its heat dissipation method is relatively simple. When multiple energy storage converters work at full load at the same time, the load of the temperature control system is relatively large;

[0005] 2. When any energy storage converter catches fire, the fire extinguishing system cannot extinguish the burning energy storage converter alone. The diffused fire extinguishing medium will cause dust or liquid to enter the unburned energy storage converter, thereby causing damage to the unburned energy storage converter.

[0006] Based on the above problems, this application document proposes a mobile integrated charging and storage device to improve the above problems. Summary of the invention

[0047] Multiple heat dissipation parts 200, multiple heat dissipation parts 200 and sealing blocks 102 are adapted, the heat dissipation parts 200 include a bearing plate 201, a first joint 202 and a second joint 203, the bearing plate 201 is fixed inside the cabinet 100, in the initial state, the inside of the bearing plate 201 is also injected with liquid fire extinguishing agent, and multiple fire extinguishing holes 204 are evenly opened at the bottom of the bearing plate 201, the first joint 202 is fixed to the upper end of the bearing plate 201, and the second joint 203 is fixed to the lower end of the bearing plate 201, when both cabinet doors 101 are in a closed state, the sealing block 102 and the bearing plate 201 are tightly fitted, and the interior of the cabinet 100 is divided into multiple isolation chambers 107 by the cooperation of the sealing block 102 and the bearing plate 201, and the multiple energy storage converters 103 and the multiple isolation chambers 107 are adapted one by one;

[0048] A plurality of partitions 300, wherein the plurality of partitions 300 are respectively mounted inside the plurality of carrier plates 201, and the plurality of partitions 300 and the plurality of fire extinguishing holes 204 are matched one by one;

[0049] Among them, the storage cavity 105, the water pump 106 and multiple supporting plates 201 form a circulating cooling passage. The water pump 106 can drive the liquid fire extinguishing agent to flow inside the circulating cooling passage. In the initial state, the isolation part 300 covers the fire extinguishing hole 204. When the heat inside the isolation cavity 107 rises sharply, the isolation part 300 adjacent to the isolation cavity 107 operates, and the liquid fire extinguishing agent inside the supporting plate 201 adjacent to the isolation cavity 107 and located at the upper end thereof is sprayed into the isolation cavity 107 through the fire extinguishing hole 204. In the initial state, the inside of the supporting plate 201 is in a sealed state.

[0050] It should be noted that, in the present embodiment, in two adjacent heat dissipation parts 200, the first joint 202 located inside the heat dissipation part 200 at the lower end is connected to the second joint 203 located inside the heat dissipation part 200 at the upper end, the first joint 202 located inside the heat dissipation part 200 at the uppermost end is connected to the output end of the water pump 106, and the second joint 203 located inside the heat dissipation part 200 at the lowermost end is connected to the return hole.

[0051] Furthermore, a buried wire tube 108 is provided inside the cabinet body 100, and a plurality of wire threading holes are provided on the outside of the buried wire tube 108. The plurality of wire threading holes and the plurality of isolation chambers 107 are matched one by one. The buried wire tube 108 is used to store lines and pipes. When both cabinet doors 101 are in a closed state, the setting of the wire threading holes will cause the isolation chamber 107 to not be an absolutely sealed space. However, since the buried wire tube 108 and the wires and pipes stored inside the wire threading holes will affect the gas flow, their sealing performance on the isolation chamber 107 is ignored here.

[0052] Specifically, a mobile carrier (not shown) is used in conjunction with the device, and the cabinet 100 is fixed on the mobile carrier. The mobile carrier can drive the cabinet 100 to move, and a temperature control module 109 is also installed on one side of a cabinet door 101.

[0053] Here, in order to better describe the working principle of the present device, when describing the fire of any energy storage inverter 103, unless otherwise specified, the isolation cavity 107 corresponding to the burning energy storage inverter 103 is recorded as isolation cavity 107-A, and the isolation cavity 107 adjacent to the burning energy storage inverter 103 is recorded as isolation cavity 107-B. The supporting plate 201 and the isolation part 300 involved in the description are adjacent to the above-mentioned burning energy storage inverter 103 and are located at its upper end or / and lower end, wherein the supporting plate 201 adjacent to the above-mentioned burning energy storage inverter 103 and located at its upper end is recorded as supporting plate 201-A, and the supporting plate 201 adjacent to the above-mentioned burning energy storage inverter 103 and located at its lower end is recorded as supporting plate 201-B. Similarly, the isolation part 300 located at its upper end is recorded as isolation part 300-A, and the isolation part 300 located at its lower end is recorded as isolation part 300-B.

[0054] Furthermore, in the present embodiment, the liquid fire extinguishing agent is preferably perfluoroacetone fire extinguishing agent. Perfluoroacetone fire extinguishing agent is a mature application. Perfluoroacetone is a colorless, odorless, transparent liquid. At normal temperature and pressure, perfluorohexanone exists in liquid form and is easily vaporized. This fire extinguishing agent has excellent environmental protection performance, and achieves fire extinguishing effects through various methods such as physical cooling, oxygen isolation and chemical inhibition. It has good insulation properties and is suitable for fire places where other fire extinguishing agents are not suitable for fire fighting and where there can be no large secondary pollution after fire extinguishing, such as large data centers, computer rooms, distribution rooms, etc.

[0055] In this embodiment, liquid fire extinguishing agent is injected into the storage chamber 105 through the water injection hole, and the water pump 106 is started. The liquid fire extinguishing agent in the storage chamber 105 is transported to the inside of the carrier plate 201 through the water pump 106 until the inside of the circulating cooling passage is completely filled with liquid fire extinguishing agent. When the energy storage converter 103 is working, a large amount of heat is released. The heat in the isolation chamber 107 is absorbed by the carrier plate 201, and the temperature control module 109 is started to drive the gas flow in the cabinet 100. Through convection, The cabinet 100 is cooled by heat dissipation. At the same time, the water pump 106 is started to drive the liquid fire extinguishing agent to circulate in the circulating cooling passage. After the low-temperature liquid fire extinguishing agent enters the carrier plate 201, it exchanges heat with the gas in the isolation chamber 107 through the carrier plate 201, and cools the cabinet 100 by conduction heat dissipation. Through the cooperation of the temperature control module 109 and the water pump 106, the device can cool the cabinet 100 by convection heat dissipation and conduction heat dissipation, avoiding the phenomenon that the temperature control module 109 is overloaded when multiple energy storage converters 103 are working at full load at the same time, thereby improving the heat dissipation efficiency and heat dissipation effect. At the same time, when a fire occurs in the cabinet 100, the liquid fire extinguishing agent can also extinguish the fire and prevent the fire from spreading, thereby greatly improving the safety of the device. When any energy storage converter 103 catches fire, the temperature inside the isolation chamber 107-A will rise sharply, and the isolation part 300-A will operate, and the load of the carrier 107-A will no longer be affected. The fire extinguishing hole 204 in the plate 201-A forms a cover, and the supporting plate 201-A changes from a sealed state to an open state. The liquid fire extinguishing agent inside the supporting plate 201-A flows out through the fire extinguishing hole 204 at the bottom thereof to extinguish the burning energy storage inverter 103 (at this time, the other supporting plates 201 are in a sealed state, and the liquid fire extinguishing agent inside them will not flow out), thereby preventing the liquid fire extinguishing agent from flowing into the unburned energy storage inverter 103 and causing damage to the unburned energy storage inverter 103.

[0056] Next, please refer to Figure 7 As shown, a plurality of guide plates 205 are fixed inside the carrier plate 201 , and the plurality of guide plates 205 are alternately fixed at two ends inside the carrier plate 201 . The interior of the carrier plate 201 forms an S-shaped flow channel through the cooperation of the plurality of guide plates 205 .

[0057] In this embodiment, the setting of the S-shaped flow channel can increase the flow time and flow path of the liquid fire extinguishing agent inside the carrier plate 201, increase the heat exchange time between the liquid fire extinguishing agent and the carrier plate 201, and thus improve the heat dissipation effect.

[0058] Secondly, please also refer to Figures 8 to 11The isolation part 300 includes a first shell 301, a second shell 302, an outer sleeve 303, a limit plate 304, a baffle 305 and a first elastic element 306. The first shell 301 is fixed to the upper end of the inner part of the carrier plate 201. The upper end of the first shell 301 is provided with a conical hole. The second shell 302 is fixed to the lower end of the inner part of the carrier plate 201. The outer sleeve 303 is slidably connected to the outer sides of the first shell 301 and the second shell 302. The first shell 301, the second shell 302 and the outer sleeve 303 form an air flow channel. The limit plate 304 is fixed to the outer sleeve 3 03, the baffle plate 305 is fixed to the middle end of the outer sleeve 303, the first elastic element 306 is assembled between the second shell 302 and the baffle plate 305, the material of the first elastic element 306 is a memory alloy, in the initial state, the air flow channel is in an open state, the first elastic element 306 is in a low-temperature phase, and the limiting plate 304 and the fire extinguishing hole 204 are tightly fitted, and the limiting plate 304 covers the fire extinguishing hole 204, wherein, when the first elastic element 306 changes from the low-temperature phase to the high-temperature phase, the height of the second elastic element 310 increases.

[0059] Furthermore, sealing elements are provided between the first shell 301 and the outer sleeve 303 and between the second shell 302 and the outer sleeve 303 to prevent the liquid fire extinguishing agent from flowing into the air flow channel.

[0060] In this embodiment, in the initial state, the first elastic element 306 is in a low-temperature phase state, the limiting plate 304 and the fire extinguishing hole 204 are tightly attached to and block the fire extinguishing hole 204, and the liquid fire extinguishing agent can flow inside the circulating cooling passage. When an energy storage converter 103 catches fire, the temperature inside the isolation cavity 107-A will rise. When the temperature inside the isolation cavity 107-A reaches the transformation temperature of the first elastic element 306, the first elastic element 306 in the isolation portion 300-A changes from the low-temperature phase state to the high-temperature phase state, and the first elastic element 306 is pushed The outer sleeve 303, the limit plate 304 and the baffle plate 305 move in the direction away from the second shell 302, so that the limit plate 304 in the isolation part 300-A no longer covers the fire extinguishing hole 204, and the supporting plate 201-A changes from a sealed state to an open state, so that the liquid fire extinguishing agent inside the supporting plate 201-A flows out through the fire extinguishing hole 204, and then extinguishes the burning energy storage inverter 103 (at this time, the other supporting plates 201 are still in a sealed state), thereby preventing other non-burning energy storage inverters 103 from being damaged due to the liquid fire extinguishing agent entering the inside.

[0061] Here, in this embodiment, only the operation process of the device when one energy storage converter 103 is on fire is described. When multiple energy storage converters 103 are on fire, the working process of the device can refer to the above embodiment, and no further details are given here.

[0062] Next, please refer to Figures 9 and 10 A sealing gasket 307 is fixed to the lower end of the limiting plate 304 . In the initial state, the sealing gasket 307 and the supporting plate 201 are tightly fitted.

[0063] Here, the material of the sealing gasket 307 is preferably flexible rubber.

[0064] In this embodiment, in the initial state, the provision of the sealing gasket 307 can improve the sealing inside the carrier plate 201 and prevent the liquid fire extinguishing agent from flowing out.

[0065] Please refer again Figures 9 to 11 The isolation part 300 also includes an inner sleeve 308, an airtight block 309 and a second elastic element 310. The inner sleeve 308 is slidably connected to the interior of the first shell 301 and is located at the upper end of the spoiler 305. The airtight block 309 is fixed to the interior of the inner sleeve 308. A frustum surface is provided at the upper end of the outer side of the airtight block 309, and the frustum surface and the conical hole are adapted. The second elastic element 310 is assembled between the first shell 301 and the inner sleeve 308. The material of the second elastic element 310 is also a memory alloy. In the initial state, the second elastic element 310 is in a low-temperature phase. When the second elastic element 310 changes from the low-temperature phase to the high-temperature phase, the height of the second elastic element 310 decreases. In the initial state, the frustum surface and the conical hole are far away from each other.

[0066] Here, a cross bar is provided on the outer side of the airtight block 309, the cross bar is fixedly connected to the inner sleeve 308, and the inner sleeve 308 is fixedly connected to the airtight block 309 via the cross bar.

[0067] In this embodiment, in the initial state, since the frustum surface and the conical hole are far away from each other, the air flow channel formed by the first shell 301, the second shell 302 and the outer sleeve 303 is in an open state, and the two adjacent isolation chambers 107 are connected to each other through the air flow channel. After the temperature control module 109 is operated, the gas inside the cabinet 100 flows between the two adjacent isolation chambers 107 through the air flow channel. When the air flow passes through the inside of the air flow channel, it can be cooled by the liquid fire extinguishing agent, thereby improving the heat dissipation efficiency and heat dissipation effect during convection heat dissipation. At the same time, when an energy storage inverter 103 catches fire, the temperature inside the isolation chamber 107-A rises. When the temperature inside the isolation chamber 107-A reaches the phase change temperature of the second elastic element 310, the isolation portion 300-A is The second elastic element 310 in the isolation part 300-B is transformed from a low-temperature phase to a high-temperature phase. The inner sleeve 308 is driven by the second elastic element 310 to move toward the first shell 301. When the conical surface at the upper end of the airtight block 309 and the conical hole at the upper end of the first shell 301 are fitted, the air flow channels at the upper and lower ends of the isolation chamber 107-A are transformed from an open state to a closed state, and the high-temperature gas cannot flow through the air flow channel, thereby preventing the fire from spreading. At the same time, after the liquid fire extinguishing agent in the carrier plate 201-A flows out, the air flow channel at the lower end of the energy storage inverter 103 is also transformed from an open state to a closed state, which can prevent the liquid fire extinguishing agent sprayed into the isolation chamber 107-A from flowing into the isolation chamber 107-B through the air flow channel at the lower end.

[0068] Please refer again Figures 9 to 11 The airtight block 309 has guide holes symmetrically provided inside, and the extension direction of the guide holes is parallel to the horizontal plane. The guide holes are slidably connected to the limit rod 311. A third elastic element 312 is arranged between the airtight block 309 and the limit rod 311. A limit hole 313 is provided on the inner wall of the first shell 301. An avoidance groove 314 is provided on the side wall of the inner sleeve 308. The limit rod 311 and the limit hole 313 as well as the limit rod 311 and the avoidance groove 314 are adapted to each other. In the initial state, the third elastic element 312 is in a low-temperature phase. When the third elastic element 312 changes from the low-temperature phase to the high-temperature phase, the length of the third elastic element 312 increases.

[0069] In this embodiment, when the energy storage converter 103 catches fire, the temperature inside the isolation chamber 107-A rises, and the second elastic element 310 is transformed from a low-temperature phase to a high-temperature phase. The airtight block 309 is driven to move by the second elastic element 310 until the airtight block 309 and the first shell 301 are tightly fitted, so that the air flow channel is transformed from an open state to a closed state. At the same time, the third elastic element 312 is transformed from a low-temperature phase to a high-temperature phase, and the limiting rod 311 is driven to move toward the direction close to the limiting hole 313 by the third elastic element 312 until the limiting rod 311 is closed. 11 is inserted into the limiting hole 313, and the airtight block 309 is limited by the cooperation of the limiting rod 311 and the limiting hole 313. When the liquid fire extinguishing agent in the supporting plate 201-A is sprayed into the isolation chamber 107-A, the airtight block 309 in the isolation part 300-B can be prevented from moving under the gravity of the liquid fire extinguishing agent, causing the air flow channel at the lower end of the energy storage inverter 103 to change from a closed state to an open state, thereby preventing the liquid fire extinguishing agent in the isolation chamber 107-A from flowing into the isolation chamber 107-B through the air flow channel at the lower end of the energy storage inverter 103.

[0070] Please refer again Fig.10 and Fig.11 A stop block 315 is provided on the outer side of the inner sleeve 308, and a guide groove 316 is provided on the inner wall of the first shell 301, and the stop block 315 and the guide groove 316 are matched with each other.

[0071] In this embodiment, when the inner sleeve 308 drives the airtight block 309 to move, the inner sleeve 308 can be guided by the cooperation of the stop block 315 and the guide groove 316 to prevent the inner sleeve 308 from rotating during the movement, thereby causing the limit rod 311 and the limit hole 313 to be misaligned.

[0072] In a preferred embodiment, the transformation temperature of the first elastic element 306 is recorded as T1, the transformation temperature of the second elastic element 310 is recorded as T2, and the transformation temperature of the third elastic element 312 is recorded as T3, and T2<T3<T1.

[0073] In this embodiment, through the above-mentioned scheme, after the energy storage inverter 103 catches fire, during the process of the temperature inside the isolation cavity 107-A rising, the second elastic element 310 is preferentially transformed from the low-temperature phase state to the high-temperature phase state, so that the airflow channel is preferentially transformed from an open state to a closed state, so that a sealed space is formed inside the isolation cavity 107-A. Secondly, the third elastic element 312 is transformed from the low-temperature phase state to the high-temperature phase state, and the airtight block 309 is limited by the cooperation of the limiting rod 311 and the limiting hole 313 to prevent the airflow channel from changing to an open state again. Finally, the first elastic element 306 is transformed from the low-temperature phase state to the high-temperature phase state, so that the liquid fire extinguishing agent in the supporting plate 201-A is sprayed into the isolation cavity 107-A to extinguish the burning energy storage inverter 103.

[0074] The working principle of the present invention is:

[0075] Liquid fire extinguishing agent is injected into the storage cavity 105 through the water injection hole. When the energy storage converter 103 is working, the temperature control module 109 is started to drive the gas flow inside the cabinet 100, and the inside of the cabinet 100 is cooled by convection heat dissipation. At the same time, the water pump 106 is started to drive the liquid fire extinguishing agent to circulate in the circulating cooling passage through the water pump 106, and the inside of the cabinet 100 is cooled by conduction heat dissipation. Through the cooperation of the temperature control module 109 and the water pump 106, the device can cool the inside of the cabinet 100 by convection heat dissipation and conduction heat dissipation, thereby improving the heat dissipation efficiency and heat dissipation effect of the device. At the same time, when a fire occurs inside the cabinet 100, the liquid fire extinguishing agent can also extinguish the fire and prevent the fire from spreading, thereby greatly improving the safety of the device. When any one When an energy storage inverter 103 catches fire, the temperature inside the isolation cavity 107-A rises, the isolation part 300-A operates, and the second elastic element 310, the limiting rod 311 and the first elastic element 306 are transformed from the low-temperature phase state to the high-temperature phase state in turn. After the second elastic element 310 changes its state, the air flow channel is transformed from an open state to a closed state. After the limiting rod 311 changes its state, it can limit the airtight block 309. After the first elastic element 306 changes its state, the liquid fire extinguishing agent inside the supporting plate 201 at the upper end of the energy storage inverter 103 flows out through the fire extinguishing hole 204 to extinguish the fire, so that the device can extinguish the burning energy storage inverter 103. At the same time, the liquid fire extinguishing agent will not enter the interior of other energy storage inverters 103, thereby avoiding damage to the unburned energy storage inverter 103.

[0076] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
