[0002] The prefabricated cabin of lithium iron phosphate battery is a highly integrated energy storage device inside. It has only a small number of interfaces with the external interfaces, greatly reducing the workload of integrated design, and having the characteristics of small floor area, flexible installation, good mobility and expandability. A large amount of heat is generated during the operation of the battery cells in the prefabricated cabin of lithium iron phosphate battery, resulting in too high operating temperature of the battery cells, greatly increasing the instability of lithium ions. Therefore, the heat dissipation of the battery cells in the battery cabin is very crucial.

[0003] Currently, the heat dissipation means of the energy storage battery cabin usually adopts the air-cooled heat dissipation method. And the prefabricated cabin of lithium iron phosphate battery is generally placed outdoors. In the rainy season in summer, when the rain is heavy, some rainwater may enter the battery cabin along the exhaust port, affecting the normal operation of the internal devices in the battery cabin. Summary of the Invention

In the rainy season in summer, some rainwater may enter the battery cabin along the exhaust port, affecting the normal operation of the internal devices in the battery cabin.

[0005] An exhaust device for an energy storage battery container that prevents rainwater from entering includes an exhaust frame. The exhaust frame is in a hollow rectangular structure and is fixed at the exhaust port of the container by means of a rectangular fixing frame. A trigger assembly is provided on the front wall of the exhaust frame. The four sides of the exhaust frame are in a hollow structure and a rain shielding assembly is further provided outside the exhaust frame. The trigger assembly is triggered by rainwater and the trigger assembly inflates the inflatable airbag of the rain shielding assembly. After the inflatable airbag is inflated, it pushes the rain shielding side plate of the rain shielding assembly to rotate towards the edge of the exhaust frame so that the edge of the exhaust frame encloses a rectangular rain shielding cavity.

[0006] Preferably, the rain shielding assembly includes a protruding portion and a hinge shaft. An inflatable airbag is fixedly connected to the outer wall of the exhaust air frame along its circumference, and the inflatable airbag and the exhaust air frame are coaxially structured. An inflation pipe is provided at the top of the inflatable airbag and extends into the exhaust air frame. The protruding portions are fixedly connected to the outer walls on four sides of the exhaust air frame, and the middle of the protruding portion is rotatably connected to the rain shielding side plate by means of the hinge shaft. A reset assembly is provided on the rain shielding side plate. The inflatable airbag is located between the fixed frame and the protruding portion, and after the inflatable airbag is inflated, it pushes the rain shielding side plate to rotate towards the edge of the exhaust air frame.

[0007] Preferably, the triggering assembly includes a water tank, a trigger switch, an exhaust fan, a lever, and a rotating shaft. The exhaust fan is provided inside the inflation pipe, and a trigger switch for controlling the exhaust fan is provided outside the inflation pipe. A rotating groove is formed in the front wall of the exhaust air frame, and the rotating shaft is horizontally rotatably connected in the rotating groove. The rotating shaft is fixedly connected to the lever, and the two ends of the lever are respectively located inside and outside the exhaust air frame. One end of the lever is located below the trigger switch, and a water tank is provided at the other end of the lever. The distance between the water tank and the exhaust air frame is greater than the width of the rain shielding side plate. A spring is provided between the bottom of the lever and the bottom of the rotating groove.

[0008] Preferably, a water outlet is formed at the bottom of the water tank. The water tank is provided with an opening, and a filter screen is provided at the opening. The aperture of the water outlet is smaller than the aperture of the opening at the top of the water tank.

[0009] Preferably, an exhaust pipe is communicated with the bottom of the inflatable airbag, and the aperture of the exhaust pipe is smaller than the aperture of the inflation pipe.

[0010] Preferably, the width of the rain shielding side plate is greater than the end of the exhaust air frame, and the edge of the inflated inflatable airbag extends to the edge of the rain shielding side plate.

[0011] Preferably, the reset assembly includes a reset coil spring, a magnet one, and a magnet two. A limiting groove is formed in the middle of the protruding portion. One side of the rain shielding side plate is fixedly connected with the hinge shaft. The two ends of the hinge shaft are respectively rotatably connected to the two sides of the limiting groove, and a reset coil spring is wound around the hinge shaft. The magnet one is embedded on the back surface of the rain shielding side plate, and the magnet two is embedded on the fixed frame. The magnet one and the magnet two attract each other.

[0012] The present invention has the following advantages:

[0013] When the rainwater tank is filled, the tank drives the lever to rotate downward, and the end of the lever located at the trigger switch will tilt upward, thereby pressing the trigger switch to energize the exhaust fan to rotate. Then, the sucked and discharged gas enters the inflatable airbag. During the rain shielding process, the hot air discharged from the battery container is continuously sucked, and the exhaust air volume is not affected. The inflatable airbag is inflated, and it will inevitably expand after inflation and extend towards the protruding part. Then, the inflatable airbag is used to push the rain shielding side plate to rotate towards the edge of the exhaust air frame, so that the edge of the exhaust air frame encloses a rectangular rain shielding cavity. The existence of the rain shielding cavity extends the length of the exhaust air frame, and the inflatable airbag is wrapped on the surface of the rain shielding cavity, which can prevent rainwater from directly entering the inside from the edge of the hollow exhaust air frame. When the rain gradually decreases, the water inside the tank gradually drains out of the tank through the water outlet. After the tank loses weight, the spring releases energy, and then the lever returns to the horizontal position. Then, the end of the lever located at the trigger switch will move downward and away from the trigger switch. In this way, the exhaust fan is powered off, and the inflatable airbag can no longer be inflated and can only exhaust. The gas inside the inflatable airbag is directly discharged through the exhaust pipe, and then the inflatable airbag shrinks. The reset torsion spring releases energy, and the rain shielding side plate returns to the initial position and is fixed by magnet one and magnet two 42. In this way, the exhaust air volume of the exhaust air frame is not affected either. The present invention effectively prevents rainwater from entering the exhaust air frame and does not affect the exhaust air volume of the exhaust air frame during rain shielding.

[0024] The following will further describe the specific embodiments of the present invention in detail with reference to the accompanying drawings and through the description of the embodiments, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0025] As Figures 1-5 shown, the present invention provides an exhaust device for an energy storage battery container that avoids rainwater entry, including an exhaust frame 1. The exhaust frame 1 has a hollow rectangular structure and is fixed at the exhaust port of the container by means of a rectangular fixing frame 10. A trigger component 3 is provided on the front wall of the exhaust frame 1. The four sides of the exhaust frame 1 are in a hollow structure and a rain shield component 2 is further provided outside the exhaust frame 1. The trigger component 3 is triggered by rainwater and the trigger component 3 inflates the inflatable airbag 20 of the rain shield component 2. After the inflatable airbag 20 is inflated, it pushes the rain shield side plate 21 of the rain shield component 2 to rotate towards the edge of the exhaust frame 1 so that the edge of the exhaust frame 1 encloses a rectangular rain shield cavity.

[0026] The rain shield component 2 includes a protruding portion 22 and a hinge shaft 25. The outer wall of the exhaust frame 1 is fixedly connected with the inflatable airbag 20 along its circumference and the inflatable airbag 20 and the exhaust frame 1 are in a coaxial structure. An inflation pipe 23 is provided at the top of the inflatable airbag 20 and the inflation pipe 23 extends into the exhaust frame 1. The protruding portion 22 is fixedly connected to the outer walls of the four sides of the exhaust frame 1 and the rain shield side plate 21 is rotatably connected to the middle of the protruding portion 22 by means of the hinge shaft 25. A reset component 4 is provided on the rain shield side plate 21. The inflatable airbag 20 is located between the fixing frame 10 and the protruding portion 22 and after the inflatable airbag 20 is inflated, it pushes the rain shield side plate 21 to rotate towards the edge of the exhaust frame 1. The bottom of the inflatable airbag 20 is communicated with an exhaust pipe 24, and the aperture of the exhaust pipe 24 is smaller than the aperture of the inflation pipe 23. The width of the rain shield side plate 21 is greater than the end of the exhaust frame 1. The edge of the inflated inflatable airbag 20 extends to the edge of the rain shield side plate 21. The reset component 4 includes a reset coil spring 40, a magnet 1 41 and a magnet 2 42. A limiting groove is formed in the middle of the protruding portion 22. One side of the rain shield side plate 21 is fixedly connected with the hinge shaft 25. The two ends of the hinge shaft 25 are respectively rotatably connected to the two sides of the limiting groove and the reset coil spring 40 is wound around the hinge shaft 25. The magnet 1 41 is embedded on the back of the rain shield side plate 21, and the magnet 2 42 is embedded on the fixing frame 10. The magnet 1 41 and the magnet 2 42 attract each other.

[0027] When the rain shield assembly 2 is triggered, the inflatable airbag 20 is inflated. After inflation, it will inevitably expand. Since the inflatable airbag 20 is arranged between the protruding part 22 and the fixing frame 10, when the inflatable airbag 20 is inflated and expands, it will inevitably extend towards the protruding part 22. A limiting groove is arranged at the top of the protruding part 22, and a rain shield side plate 21 is rotatably connected in the limiting groove by means of a hinge shaft. In the case of no rain, the rain shield side plate 21 maintains balance by means of the suction force between the first magnet and the second magnet and can be in an inclined or vertical state, and the reset coil spring 40 on the hinge shaft 25 is not stretched. When it rains, the inflatable airbag 20 is inflated and expands, and will extend towards the protruding part 22. Then, the inflatable airbag 20 is used to push the rain shield side plate 21 to rotate towards the edge of the exhaust air frame 1, so that a rectangular rain shield cavity is formed by the edges of the exhaust air frame 1. The existence of the rain shield cavity extends the length of the exhaust air frame 1, and the inflatable airbag 20 is wrapped on the surface of the rain shield cavity, which can prevent rainwater from directly entering the inside of the exhaust air frame through the hollow edges. After the rain stops, the gas inside the inflatable airbag 20 is directly discharged through the exhaust pipe 24, and then the inflatable airbag 20 contracts, the reset coil spring 40 releases energy, and the rain shield side plate 21 returns to its initial position and is fixed by the first magnet 41 and the second magnet 42. In this way, the exhaust air volume of the exhaust air frame 1 is not affected either.

[0028] The trigger assembly 3 includes a water tank 34, a trigger switch 35, a suction fan 37, a lever 33 and a rotating shaft 31. The suction fan 37 is arranged inside the inflatable pipe 23, and the trigger switch 35 for controlling the suction fan 37 is arranged outside the inflatable pipe 23. A rotating groove 30 is formed in the front wall of the exhaust air frame 1, and the rotating shaft 31 is horizontally rotatably connected in the rotating groove 30. The rotating shaft 31 is fixedly connected inside the lever 33, and both ends of the lever 33 are located inside and outside the exhaust air frame 1 respectively. One end of the lever 33 is located below the trigger switch 35, and the other end of the lever 33 is provided with the water tank 34. The distance between the water tank 34 and the exhaust air frame 1 is greater than the width of the rain shield side plate 21. A spring 32 is arranged between the bottom of the lever 33 and the bottom of the rotating groove 30. A water outlet 36 is formed at the bottom of the water tank 34. The water tank 34 is provided with an opening, and a filter screen is arranged at the opening. The aperture of the water outlet 36 is smaller than the aperture of the top opening of the water tank 34.

[0029] When it rains, the water tank 34 is first filled with rainwater. Since the aperture of the water outlet 36 is smaller than the aperture of the top opening of the water tank 34, the amount of water inside the water tank 34 is also sufficient. When the water tank 34 is filled, the water tank 34 drives the lever 33 to rotate downward, and the lever 33 will become unbalanced, causing the spring 32 to be compressed. Based on the lever principle, the end of the lever 33 located at the trigger switch 35 will tilt upward, thereby pressing the trigger switch 35 to energize the exhaust fan 37 to rotate, so that the sucked exhaust gas enters the inflatable airbag 20. During the rain shielding process, the hot air discharged from the battery container is continuously sucked, and the exhaust air volume is not affected. When the rain gradually subsides, the water inside the water tank 34 gradually drains out of the water tank 34 through the water outlet 36. After the water tank 34 loses weight, the spring 32 releases energy, causing the lever to return to the horizontal position. Then, the end of the lever 33 located at the trigger switch 35 will move downward, away from the trigger switch, so that the exhaust fan 37 is powered off, and the inflatable airbag 20 can no longer be inflated and can only exhaust air, causing the rain shielding side plate 21 to return to the initial position.

[0030] Working principle: When it rains, the water tank 34 is first filled with rainwater. Since the aperture of the water outlet 36 is smaller than the aperture of the top opening of the water tank 34, the amount of water inside the water tank 34 is also sufficient. When the water tank 34 is filled, the water tank 34 drives the lever 33 to rotate downward, and the lever 33 will be unbalanced, thereby compressing the spring 32. Based on the lever principle, the end of the lever 33 located at the trigger switch 35 will tilt upward, thereby pressing the trigger switch 35 to energize and rotate the exhaust fan 37. Then, the sucked and discharged gas enters the inflatable airbag 20. During the rain shielding process, the hot air discharged from the battery container is continuously sucked, and the exhaust air volume is not affected. The inflatable airbag 20 is inflated and will inevitably expand after inflation. Since the inflatable airbag 20 is arranged between the protruding part 22 and the fixing frame 10, when the inflatable airbag 20 is inflated and expands, it will inevitably extend towards the protruding part 22. A limit groove is provided at the top of the protruding part 22, and the rain shielding side plate 21 is rotatably connected in the limit groove by means of a hinge shaft. In the case of no rain, the rain shielding side plate 21 maintains balance by the suction force between the first magnet and the second magnet and can be in an inclined or vertical state, and the return coil spring 40 on the hinge shaft 25 is not stretched. When it rains, the inflatable airbag 20 is inflated and expands, and will extend towards the protruding part 22. Then, the inflatable airbag 20 is used to push the rain shielding side plate 21 to rotate towards the edge of the exhaust air frame 1, so that a rectangular rain shielding cavity is formed by the edge of the exhaust air frame 1. The existence of the rain shielding cavity extends the length of the exhaust air frame 1, and the inflatable airbag 20 is wrapped on the surface of the rain shielding cavity, which can prevent rainwater from directly entering the inside from the edge of the hollow exhaust air frame. When the rain gradually becomes smaller, the water inside the water tank 34 gradually drains out of the water tank 34 through the water outlet 36. After the water tank 34 loses weight, the spring 32 releases energy, and then the lever returns to the horizontal position. Then, the end of the lever 33 located at the trigger switch 35 will move downward and away from the trigger switch, so that the exhaust fan 37 is powered off, and then the inflatable airbag 20 cannot continue to be inflated and can only exhaust. The gas inside the inflatable airbag 20 is directly discharged through the exhaust pipe 24, and then the inflatable airbag 20 contracts, and the return coil spring 40 releases energy, and the rain shielding side plate 21 returns to the initial position and is fixed by the first magnet 41 and the second magnet 42. In this way, the exhaust air volume of the exhaust air frame 1 is not affected either.

[0031] The above has described the present invention in an exemplary manner with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the inventive concept and technical solutions of the present invention, or the inventive concept and technical solutions of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
