Description

Technical Field

[0001] The present invention relates to the technical field of ships, and more specifically, to a fire extinguishing protection device for a power battery in a ship cabin. Background Art

[0002] With the improvement of environmental awareness and the demand for a higher experience in ships, smart ships are gradually becoming people's choice as an environmentally friendly, energy-saving and comfortable means of transportation. As the power source of smart ships, new energy batteries can greatly improve the endurance of ships. Although new energy batteries have excellent performance, they may also have thermal runaway due to factors such as charging, discharging, short circuit, aging or impact and extrusion. Once the above situation occurs in the battery compartment of a smart ship, the battery may be damaged and power may be lost at the least, or fire and explosion may occur at the worst, endangering the safety of life and property.

[0003] Based on this, we provide a fire extinguishing protection device for in-cabin power batteries for ships. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a fire extinguishing protection device for a power battery in a ship cabin, which can ensure that the abnormal condition of the battery can be eliminated as soon as possible after the battery becomes abnormal. At the same time, the structure is simple and does not have a high-precision structural design. It is an easy-to-process and implement solution with strong operability.

[0005] The present invention provides a fire extinguishing protection device for a power battery in a ship cabin, which adopts the following technical solution:

[0006] A fire extinguishing protection device for a power battery in a ship cabin, comprising a hull, a battery compartment being provided on the hull, a battery being arranged inside the battery compartment, and a water pump arranged inside the hull; a seabed valve being arranged in the battery compartment; a drainage end of the water pump being connected to the seabed valve through a fire extinguishing pipe; and a sensor being arranged in the battery compartment, for detecting the temperature and smoke in the battery compartment, and turning on the water pump and the seabed valve.

[0007] Preferably, the water inlet end of the water pump is arranged at the bottom of the hull through a fixed end cover.

[0008] Preferably, a pressure relief port is provided at the bottom of the battery, and the pressure relief port corresponds to the position of the drainage hole of the seabed valve.

[0009] Preferably, the inner wall of the battery compartment is adhered with a fireproof and heat-insulating layer, and the batteries are arranged in the fireproof and heat-insulating layer.

[0010] Preferably, a liquid compartment is further provided on the top of the battery compartment, and a liquid box is provided in the liquid compartment.

[0011] In summary, the present invention includes the following beneficial technical effects:

[0012] 1. When the battery has thermal runaway and catches fire due to abnormal working conditions, the sensor detects the battery abnormality, and the controller immediately opens the seabed valve and the water pump. The water pump draws external water into the battery compartment and fills the battery compartment to extinguish the fire and cool it down. The battery works normally, the seabed valve is in a closed state, and the water pump does not work. Through this structural design, it can be ensured that the battery abnormality can be resolved as soon as possible after the battery abnormality occurs. At the same time, the structure is simple and does not have a high-precision structural design. It is a solution that is easy to process and implement and has strong operability.

[0013] 2. When the sensor detects that the battery temperature is high, the controller can also open the water pump and the solenoid valve in the inlet pipe (the seabed valve is closed) to pump external water into the cooling jacket frame and discharge it to the outside through a pipe, thereby realizing water cooling circulation and cooling the battery by water, thereby ensuring the stability of the battery operation.

Figure 1 to Figure 2 A fire extinguishing protection device for a power battery in a ship cabin comprises a hull 1, a water pump 4, a seabed valve 5 and a sensor 7. A battery compartment 2 is provided on the hull 1, a battery 3 is arranged inside the battery compartment 2, and the water pump 4 is arranged in the hull 1; a seabed valve 5 (solenoid valve) is arranged in the battery compartment 2; a discharge end of the water pump 4 is connected to the seabed valve 5 through a fire extinguishing pipe 6; the sensor 7 is arranged in the battery compartment 2, for detecting the temperature and smoke in the battery compartment 2, and opening the water pump 4 and the seabed valve 5.

[0027] Specifically, the sensor 7 is a smoke sensor (MQ-2 gas sensor) and a temperature sensor (TDKB58703M1103A* temperature sensor; DC / DC temperature sensor (such as T02N113A type), which is used to detect the temperature and smoke conditions in the battery compartment 2, and is also equipped with a controller (PLC controller, computer, CPU chip, etc.).

[0028] When the battery 3 experiences thermal runaway and catches fire due to abnormal operating conditions, the sensor 7 detects that the battery 3 is abnormal, and the controller immediately opens the seabed valve 5 and the water pump 4. The water pump 4 pumps external water into the battery compartment 2 and fills the battery compartment 2 to extinguish the fire and cool it down. The battery 3 works normally, the seabed valve 5 is in a closed state, and the water pump 4 does not work.

[0029] Through this structural design, it can be ensured that the abnormal condition of the battery can be resolved immediately after the battery abnormality occurs. At the same time, the structure is simple and does not require high-precision structural design. It is an easy-to-process and implement solution with strong operability.

[0030] like Figure 1 and Figure 2 As shown, the water inlet end of the water pump 4 is arranged at the bottom of the hull 1 through a fixed end cover 8.

[0031] like Figure 1 and Figure 2 As shown, a pressure relief port 9 is provided at the bottom of the battery 3 , and the pressure relief port 9 corresponds to the position of the drain hole of the seabed valve 5 .

[0032] like Figure 1 and Figure 2 As shown, the inner wall of the battery compartment 2 is adhered with a fireproof and heat-insulating layer 10 , and the battery 3 is arranged in the fireproof and heat-insulating layer 10 .

[0033] Specifically, a fireproof and heat-insulating layer 10 is provided, and the pressure relief port 9 of the battery 3 is arranged at the bottom, thereby adjusting the flame to spread unidirectionally toward the bottom.

[0034] like Figure 1 and Figure 2 As shown, a liquid compartment 11 is further provided on the top of the battery compartment 2 , and a liquid box 12 is provided in the liquid compartment 11 . The liquid box 12 can be detachably arranged in the liquid compartment 11 , or can be integrally formed with the liquid compartment 11 .

[0035] Specifically, by providing the liquid tank 11, double protection can be used.

[0036] Embodiment 2

[0037] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 3 and Figure 5 As shown, in order to better realize the present invention, the following arrangement is particularly adopted: in this embodiment, a cooling jacket frame 13 is arranged on the top of the battery 3, one end of the cooling jacket frame 13 is connected to a discharge pipe 14, a one-way valve is arranged in the discharge pipe 14, the other end of the cooling jacket frame 13 is connected to an inlet pipe 15, a solenoid valve is arranged in the inlet pipe 15, a three-way joint is arranged at the drainage end of the water pump 4, and two drainage ends of the three-way joint are connected to the inlet pipe 15, and the other is connected to the fire extinguishing pipe 6.

[0038] Specifically, when the sensor 7 detects that the temperature of the battery 3 is high, the controller can also open the water pump 4 and the solenoid valve in the inlet pipe 15 (the seabed valve 5 is in a closed state), pump external water into the cooling jacket frame 13, and discharge it to the outside through the discharge pipe 14, thereby realizing a water cooling cycle and cooling the battery 3 by water, thereby ensuring the working stability of the battery 3.

[0039] Embodiment 3

[0040] This embodiment is further optimized on the basis of the above embodiment 1, and the same parts as the above technical solution will not be repeated here. Figure 6 and Figure 7 As shown, in order to better realize the present invention, the following arrangement is particularly adopted: in this embodiment, a filter panel 16 is arranged at the bottom of the hull 1 at a position relative to the water suction end of the water pump 4, and the side of the filter panel 16 is rotatably connected to a rotating shaft 17, and the side end of the rotating shaft 17 is arranged outside the filter panel 16. A driving blade 18 is arranged in the middle of the rotating shaft 17, and the side end of the rotating shaft 17 is rotatably connected to a cleaning roller 19. When the water pump 4 works, water flows in, thereby driving the driving blade 18 to rotate, thereby rotating the rotating shaft 17. The rotation of the rotating shaft 17 drives the cleaning roller 19 to rotate on the outer side of the filter panel 16, thereby cleaning the impurities on the filter panel 16. Through this structural design, the impurities entering the battery compartment 2 or the cooling jacket frame 13 can be reduced.
