Description

Technical Field

[0001] The present invention relates to the technical field of polar ocean scientific research, and particularly relates to a marine lithium battery safety charging and storage device, a using method thereof, and a scientific research ship, and relates to the safe storage and charging of lithium batteries carried on a polar scientific research ship at sea. Background Art

[0002] The polar regions are rich in natural resources. People's transportation and other activities in the polar regions are becoming increasingly frequent, and countries around the world, including China, are paying more and more attention to polar scientific research and development work, and are exploring and researching the polar regions more and more deeply.

[0003] In polar scientific research and development, an indispensable means of transportation is a polar scientific research ship, such as an icebreaker. At the same time, various unmanned equipment is needed during polar exploration, and various unmanned equipment needs to be driven by lithium batteries with a relatively high energy density. The polar scientific research ship sails to the polar regions, with a long journey, bad sea conditions, and large ice-breaking vibrations.

[0004] At present, the Maritime Safety Administration of the Ministry of Transport has organized the formulation of regulations such as the International Maritime Dangerous Goods Code and the Safety Technical Requirements for Ships Carrying Lithium Batteries. These are all general requirements for shipping large quantities of lithium battery bulk cargo by shipping vessels, and their requirements for the power, packaging, shipping, and labeling of lithium batteries. These regulations mainly address the safety of lithium batteries during ship transportation and prevent safety accidents caused by improper handling. They are all limited to passive safety requirements, mainly putting forward requirements for lithium batteries and their packaging, and lacking active countermeasures.

[0005] At present, there are more and more unmanned equipment on scientific research ships for polar scientific research, and at the same time, corresponding equipment is needed to store and charge lithium batteries. Lithium batteries are increasingly widely used due to their high density and low volume space requirements. However, due to the very active chemical properties of lithium metal, its storage, use, charging, etc. have very high environmental requirements. In addition, lithium batteries often cause explosions and fires, causing adverse effects on people's lives and property. Polar scientific research ships mainly sail in polar waters, far from land-based support. In the event of a lithium battery explosion and fire, the on-site emergency disposal means are limited. In severe cases, it will endanger the safety of the ship and the crew. Moreover, for scientific research application equipment, due to its strong exploratory and innovative nature, many equipment and the lithium batteries that drive them are customized products, and the requirements of the International Maritime Dangerous Goods Code and the Safety Technical Requirements for Ships Carrying Lithium Batteries are difficult to meet the actual use needs.

[0006] When a polar research vessel carries lithium batteries to the polar regions for use, which is different from conventional transportation and charging, it also presents the following characteristics: The polar research vessel sails through high temperatures near the equator and low temperatures in the polar regions. The temperature change has a great impact on the safe storage and use of lithium batteries. For example, for a polar icebreaker, under the icebreaking condition, there are huge vibrations, and the impact on the safe storage of lithium batteries is much greater than that of ordinary ships. The polar research vessel not only involves the transportation of lithium batteries, but mainly focuses on the application of lithium batteries, involving charging and discharging. Charging and discharging are high-risk links for the safety of lithium batteries. The polar research vessel is far from shore-based support, and it is impossible to obtain more external support for dealing with the disaster of lithium battery combustion and explosion. It can only rely on its own capabilities, and the safety requirements are higher.

[0007] Therefore, there is an urgent need to invent a lithium battery safety storage device suitable for polar research vessels to solve the problems of safe storage and safe charging of lithium batteries in polar expeditions. Summary of the Invention

[0011] Furthermore, the first top lithium battery dedicated fire extinguishing agent nozzle is composed of a top box fixed installation pipeline, a top 360-degree movable joint, a top capacity increasing buffer section, and a top atomizing nozzle connected in sequence; the top capacity increasing buffer section and the top atomizing nozzle are arranged vertically, and the top atomizing nozzle faces downward.

[0012] Furthermore, the first side lithium battery dedicated fire extinguishing agent nozzle is composed of a side box fixed installation pipeline, a side 360-degree movable joint, a side capacity increasing buffer section, and a side atomizing nozzle connected in sequence; the side capacity increasing buffer section and the side atomizing nozzle are arranged horizontally.

[0013] Furthermore, each battery storage box in the battery storage cabinet is separated individually; a shock-absorbing storage platform for preventing lithium batteries is provided inside each battery storage box.

[0015] Furthermore, heat-insulating and fire-proof cotton is provided inside each battery storage box for protection.

[0016] Furthermore, the size of the box is the standard container size, and the structural strength meets the requirements of container stacking and explosion impact.

[0017] A method for using a marine lithium battery safety charging and storage device. The early warning and control center monitors the charger equipment box and the lithium battery charging part in the charging box through the first temperature and smoke sensor, and monitors the battery storage box in the battery storage cabinet through the second temperature and smoke sensor. The second temperature and smoke sensor can detect the internal temperature and environmental changes of the battery storage box in real time and send signals to the early warning and control center, and the early warning and control center gives an early warning. If a fire occurs during the lithium battery charging process, when the first temperature and smoke sensor detects that the internal temperature of the charger equipment box and / or the lithium battery charging part exceeds the set temperature, or there is smoke, the early warning and control center issues an early warning signal and controls the automatic activation of the first top lithium battery special fire extinguishing agent nozzle and the first side lithium battery special fire extinguishing agent nozzle for cooling and fire extinguishing. If a fire occurs in the battery storage box, when the second temperature and smoke sensor detects that the internal temperature of the battery storage box exceeds the set temperature, or there is smoke, the early warning and control center issues an early warning signal and controls the automatic activation of the second top lithium battery special fire extinguishing agent nozzle and the second side lithium battery special fire extinguishing agent nozzle for cooling and fire extinguishing. When the staff receives the early warning alarm and arrives at the scene, if the early warning is caused by lithium battery charging, open the electromagnetic gate under the lithium battery charging part to make the burning lithium battery fall and immerse it under the liquid level of the fire extinguishing water tank to extinguish the lithium battery.

[0018] An oceanographic research ship is equipped with an emergency jettison system. The emergency jettison system is set on the deck of the oceanographic research ship. The emergency jettison system includes an emergency jettison platform and a hydraulic jack. One end of the emergency jettison platform is hinged to the deck. The hydraulic jack is arranged under the emergency jettison platform and is connected to the middle of the emergency jettison platform. The hydraulic jack can push the emergency jettison platform to rotate along the hinged end with the deck. A marine lithium battery safety charging and storage device is set on the emergency jettison platform. When the lithium battery in the marine lithium battery safety charging and storage device catches fire and explodes and cannot be controlled, the emergency jettison system is started automatically or manually, and the hydraulic jack is used to lift the emergency jettison platform, so that the emergency jettison platform rotates and tilts, thereby jettisoning the marine lithium battery safety charging and storage device set on the emergency jettison platform to ensure the overall safety of the oceanographic research ship.

[0019] Compared with the prior art, the present invention has the following advantages and technical effects: The marine lithium battery safety charging and storage device of the present invention is provided with a charging box, in which the charger equipment box, the lithium battery charging part and the fire extinguishing water tank are arranged in sequence from top to bottom. The lithium battery charging part is the high-risk battery charging end, and an electromagnetic gate is arranged at its bottom.

[0031] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the examples can be practiced without these specific details.

[0032] Meanwhile, in this specification, descriptions related to directions, such as up, down, left, right, front, back, inside, outside, longitudinal, transverse, vertical, horizontal, etc., indicate the direction or positional relationship based on the direction or positional relationship shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as a limitation on the present invention.

[0033] As Figure 1-2 shown, the marine lithium battery safety charging and storage device of the present invention includes a box body 1, a battery storage cabinet 2 and a charging box 3 provided inside the box body 1. A door 4 is provided in the middle of one end of the box body 1. A walkway 5 is in the middle inside the box body, and the battery storage cabinet 2 and the charging box 3 are arranged on both sides of the walkway. The battery storage cabinet 2 includes a plurality of mutually separated battery storage boxes 21 to minimize the risk of mutual combustion and explosion transmission between lithium batteries.

[0034] Among them, the charging box 3 is arranged on the side close to the door 4, and the battery storage cabinet 2 is located on the inner side relatively far from the door 4. The door 4 is designed as a fireproof escape structure that opens outwards. Since the charging box 3 is arranged on the side close to the door 4, on the one hand, it is convenient for the operator to enter the box body to charge the lithium battery, and on the other hand, the lithium battery is most likely to catch fire during the charging process. The charging box 3 being close to the door 4 also facilitates safe operation in case of fire.

[0035] As Figure 1 and 3 shown, the charging box 3 is composed of a charger equipment box 31, a lithium battery charging part 32, and a fire extinguishing water tank 33. The charger equipment box 31, the lithium battery charging part 32, and the fire extinguishing water tank 33 are arranged in sequence from top to bottom. The inside of the charger equipment box 31 is mainly set with various electrical appliances for charging lithium batteries, and the lithium battery charging part 32 is a placement space for charging lithium batteries. Since the risk of fire in lithium batteries during the charging process is the greatest, belonging to the high-risk battery charging end, and the charger equipment box 31 has a relatively lower risk of catching fire compared to the lithium battery charging part 32, belonging to the low-risk battery charging end. Therefore, the fire extinguishing water tank 33 is arranged below the lithium battery charging part 32 to facilitate extinguishing the burning lithium battery, thereby minimizing the risk to the greatest extent.

[0036] An electromagnetic gate 38 is provided at the bottom of the lithium battery charging part 32. In the case of a fire in the lithium battery 39 inside the lithium battery charging part 32, the electromagnetic gate 38 can be opened, so that the lithium battery 39 inside the lithium battery charging part 32 falls into the fire extinguishing water tank 33 through the opened electromagnetic gate 38. The fire extinguishing water tank 33 is filled with water or a solution mixed with a fire extinguishing agent to extinguish the burning lithium battery 39.

[0037] Preferably, the box body 1 is arranged in a movable manner, is made of steel structure, and has the dimensions of a standard container. The structural strength meets the requirements of corresponding container stacking (not exceeding 3 layers) and explosion and impact. The box body 1 can also directly adopt a standard container. Using a standard container for the box body, on the one hand, enables the marine lithium battery safe charging and storage device of the present invention to be directly transformed using existing containers, facilitating manufacturing, and on the other hand, is also convenient for marine ships or land transportation. Due to the low temperature environment in polar regions, it is necessary to insulate the marine lithium battery safe charging and storage device to ensure the performance of the lithium batteries in the device in the low temperature environment. Therefore, a heat preservation layer is provided inside the box body 1, and the heat preservation layer uses heat-insulating and high-temperature-resistant fireproof cotton that can withstand a high temperature of 1260 degrees Celsius for heat preservation and heat insulation, meeting the usage requirements in high temperatures at the equator and low temperatures in polar regions.

[0038] At one end of the box body 1 opposite to the door 4, a fire extinguishing tank 6, an air conditioner - dehumidifier 7, and a warning and control center 8 are provided. By using the air conditioner - dehumidifier 7, the temperature and humidity inside the box body 1 can be controlled to make the inside of the box body 1 reach a constant temperature and humidity state, meeting the storage requirements in the marine environment and ensuring the stability of the battery storage environment. The fire extinguishing tank 6 is filled with perfluoromethylcyclohexane as a fire extinguishing agent. Through the warning and control center 8, all the batteries inside the box body 1 can be monitored in real time, and warnings can be issued after a danger occurs.

[0039] Inside both the charger device box 31 and the lithium battery charging section 32, there are a first temperature and smoke sensor 34, a first top lithium battery dedicated fire extinguishing agent nozzle 35, a first side lithium battery dedicated fire extinguishing agent nozzle 36, and a first explosion-proof pressure relief valve 37. The first temperature and smoke sensor 34, the first top lithium battery dedicated fire extinguishing agent nozzle 35, and the first side lithium battery dedicated fire extinguishing agent nozzle 36 are all connected to the early warning and control center 8; the first top lithium battery dedicated fire extinguishing agent nozzle 35 and the first side lithium battery dedicated fire extinguishing agent nozzle 36 are also connected to the fire extinguishing tank 6.

[0040] The first temperature and smoke sensor 34 can detect the temperature and environmental changes inside the charger device box 31 and the lithium battery charging section 32 in real time during the charging process of the lithium battery, and send signals to the early warning and control center 8 to achieve early warning. If a fire occurs during the charging process of the lithium battery, it will cause the temperature inside the charger device box 31 and / or the lithium battery charging section 32 to rise or smoke to appear. When the first temperature and smoke sensor 34 detects that the temperature inside the charger device box 31 and / or the lithium battery charging section 32 exceeds the set temperature, or smoke appears, the early warning and control center 8 issues an early warning signal and controls the automatic activation of the first top lithium battery dedicated fire extinguishing agent nozzle 35 and the first side lithium battery dedicated fire extinguishing agent nozzle 36 to cool down and extinguish the fire. If the pressure inside the charger device box 31 and / or the lithium battery charging section 32 is too high, the first explosion-proof pressure relief valve 37 will automatically open for pressure relief to prevent accidents.

[0041] In addition, since a fire extinguishing water tank 33 is provided below the lithium battery charging section 32, when the staff receives the early warning alarm and arrives at the scene, the staff can manually open the electromagnetic gate 38 below the lithium battery charging section 32 to make the burning lithium battery fall and submerge it under the liquid level of the fire extinguishing water tank 33 for extinguishing the lithium battery. The fire extinguishing water tank 33 is provided with exhaust holes communicating with the external environment to prevent the pressure from accumulating and being unable to be released after the lithium battery catches fire and explodes, thus affecting the safety of other surrounding materials or ships. After the lithium battery catches fire, when the early warning and control center 8 issues an early warning signal, the charging box 3 will automatically cut off the power to prevent accidental discharge of the charging box 3.

[0042] As Figure 4-5 shown, the first top lithium battery dedicated fire extinguishing agent nozzle 35 is composed of a top box fixed installation pipeline 351, a top 360-degree movable joint 352, a top capacity increasing and buffering part 353, and a top atomizing nozzle 354 connected in sequence. The first side lithium battery dedicated fire extinguishing agent nozzle 36 is composed of a side box fixed installation pipeline 361, a side 360-degree movable joint 362, a side capacity increasing and buffering part 363, and a side atomizing nozzle 364 connected in sequence. Among them, the top capacity increasing and buffering part 353 and the top atomizing nozzle 354 are arranged vertically, and the top atomizing nozzle 354 faces downward; the side capacity increasing and buffering part 363 and the side atomizing nozzle 364 are arranged horizontally.

[0043] In order to reduce the risk of mutual combustion between batteries, each battery storage box 21 in the battery storage cabinet 2 is separated individually. As Figure 6 shown, inside each battery storage box 21, a shock-absorbing storage platform 26 for lithium batteries is provided. Inside each battery storage box 21, a second temperature and smoke sensor 23, a second top lithium battery dedicated fire extinguishing agent spray head 24, a second side lithium battery dedicated fire extinguishing agent spray head 25, and a second explosion-proof pressure relief valve 22 are provided. At the same time, heat-insulating and fire-proof cotton is provided inside each battery storage box 21 for protection.

[0044] The second temperature and smoke sensor 23, the second top lithium battery dedicated fire extinguishing agent spray head 24, and the second side lithium battery dedicated fire extinguishing agent spray head 25 are all connected to the early warning and control center 8; the second top lithium battery dedicated fire extinguishing agent spray head 24 and the second side lithium battery dedicated fire extinguishing agent spray head 25 are also connected to the fire extinguishing tank 6.

[0045] The second temperature and smoke sensor 23 can detect the temperature and environmental changes inside the battery storage box 21 in real time, and send signals to the early warning and control center 8 to achieve early warning. If a fire occurs in the battery storage box 21, it will cause the temperature inside the battery storage box 21 to rise or smoke to appear. When the second temperature and smoke sensor 23 detects that the temperature inside the battery storage box 21 exceeds the set temperature or smoke appears, the early warning and control center 8 issues an early warning signal and controls the automatic activation of the second top lithium battery dedicated fire extinguishing agent spray head 24 and the second side lithium battery dedicated fire extinguishing agent spray head 25 to cool down and extinguish the fire. If the pressure inside the battery storage box 21 is too high, the second explosion-proof pressure relief valve 22 will automatically open for pressure relief to prevent accidents.

[0046] The second top lithium battery dedicated fire extinguishing agent spray head 24 and the second side lithium battery dedicated fire extinguishing agent spray head 25 are basically the same in structure as the first top lithium battery dedicated fire extinguishing agent spray head 35 and the first side lithium battery dedicated fire extinguishing agent spray head 36.

[0047] As Figure 7-8As shown in the figure, the scientific research ship is equipped with an emergency jettison system. The emergency jettison system is arranged on the deck 10 of the scientific research ship and includes an emergency jettison platform 11 and a hydraulic jack 12. One end of the emergency jettison platform 11 is hinged to the deck. The hydraulic jack 12 is arranged below the emergency jettison platform 11 and is connected to the middle of the emergency jettison platform 11. The hydraulic jack 12 can push the emergency jettison platform 11 to rotate along the hinged end with the deck. The marine lithium battery safe charging and storage device is placed on the emergency jettison platform 11. When the lithium battery in the marine lithium battery safe charging and storage device catches fire and explodes and cannot be controlled, in order to avoid endangering the safety of the scientific research ship, the emergency jettison system can be started automatically or manually. The hydraulic jack 12 is used to lift the emergency jettison platform 11, so that the emergency jettison platform 11 rotates and tilts, thereby jettisoning the marine lithium battery safe charging and storage device arranged on the emergency jettison platform 11 to ensure the overall safety of the scientific research ship.

[0048] Preferably, rolling shafts are evenly distributed on the emergency jettison platform 11 to reduce the friction between the emergency jettison platform 11 and the marine lithium battery safe charging and storage device during the process of jettisoning the marine lithium battery safe charging and storage device, and it is easy for the marine lithium battery safe charging and storage device to slide off the emergency jettison platform 11.

[0049] The present invention also relates to a use method of a marine lithium battery safe charging and storage device, specifically as follows: The early warning and control center 8 monitors the charger equipment box 31 and the lithium battery charging part 32 in the charging box 3 through the first temperature and smoke sensor 34, and monitors the battery storage box 21 in the battery storage cabinet 2 through the second temperature and smoke sensor 23. The second temperature and smoke sensor 23 can detect the temperature and environmental changes inside the battery storage box 21 in real time and send signals to the early warning and control center 8 to achieve early warning.

[0050] If a fire occurs during the lithium battery charging process, when the first temperature and smoke sensor 34 detects that the temperature inside the charger equipment box 31 and / or the lithium battery charging part 32 exceeds the set temperature, or there is smoke, the early warning and control center 8 issues an early warning signal and controls the automatic start of the first top lithium battery special fire extinguishing agent nozzle 35 and the first side lithium battery special fire extinguishing agent nozzle 36 for cooling and fire extinguishing.

[0051] If a fire occurs in the battery storage box 21, when the second temperature and smoke sensor 23 detects that the temperature inside the battery storage box 21 exceeds the set temperature, or there is smoke, the early warning and control center 8 issues an early warning signal and controls the automatic start of the second top lithium battery special fire extinguishing agent nozzle 24 and the second side lithium battery special fire extinguishing agent nozzle 25 for cooling and fire extinguishing.

[0052] When the staff receives the early warning alarm and arrives at the scene, if the early warning is caused by lithium battery charging, open the electromagnetic gate 38 below the lithium battery charging part 32 to make the burning lithium battery drop and submerge it under the liquid level of the fire extinguishing water tank 33 to extinguish the lithium battery.
