Detailed Implementation Methods

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0017] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0018] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] Please see Figures 1 to 3The present invention relates to a water-filled fire extinguishing energy storage box, comprising an independent main frame 10, wherein the main frame 10 is a cuboid frame, and the four sides of the main frame 10 are respectively connected by screws to a first side plate 20, a second side plate 30, a third side plate 40, and a fourth side plate 50. The bottom of the main frame 10 is fixedly connected by screws to a bottom plate 60. Sealing strips are provided at the connection points between the first side plate 20, the second side plate 30, the third side plate 40, the fourth side plate 50, the bottom plate 60 and the main frame 10 to prevent water leakage.

[0020] The first side plate 20, the second side plate 30, the third side plate 40, the fourth side plate 50, and the bottom plate 60 together with the main frame 10 of the box form an independent leak-proof box.

[0021] The first side plate 20, the second side plate 30, the third side plate 40, the fourth side plate 50, and the bottom plate 60 are all made of painted cold-rolled steel.

[0022] The main frame 10 of the housing has an internal storage space for storing battery modules.

[0023] The main frame 10 of the box is provided with a partition 70, which divides the accommodating space into two small accommodating spaces. A fire water pipe 80 is installed above the partition 70 and the first side plate 20. Two fire sprinklers 81 are connected to the fire water pipe 80, and the two fire sprinklers 81 are located above the two small accommodating spaces respectively.

[0024] The first side plate 20 is provided with an overflow drain 22, which is located above the top of the battery module.

[0025] A temperature sensor is installed inside the accommodating space to monitor the internal temperature.

[0026] When a fire occurs due to battery overheating, short circuit, or other malfunctions, and the temperature reaches the self-explosion temperature (79℃) of the fire sprinkler head 81, the fire sprinkler head 81 will automatically spray water to control and extinguish the fire. Firefighting water continuously flows into the enclosure, and once full, it is discharged from the overflow drain 22, simultaneously cooling the enclosure. The batteries are completely submerged in water, preventing reignition and ensuring effective fire extinguishing. Each battery module is relatively independent; if one group of battery modules malfunctions, extinguishing the fire will not affect other modules, minimizing property damage.

[0027] The top of the partition 70 is provided with a first pipe groove 71, and the top of the first side plate 20 is provided with a second pipe groove 23. The fire water pipe 80 is mounted on the first pipe groove 71 and the second pipe groove 23.

[0028] The first side plate 20 and the second side plate 30 are arranged opposite to each other. The second side plate 30 is provided with an air inlet 31, and the first side plate 20 is provided with an air outlet 21. An air inlet fan 91 is provided inside the air inlet 31, and an air outlet fan 92 is provided inside the air outlet 21. The overflow drain outlet 22 is located below the air outlet 21. The bottom of the partition 70 is provided with a ventilation groove 72. The partition 70 is used to block the airflow, which passes through the ventilation groove 72 below, so as to better ventilate, dissipate heat and cool the battery.

[0029] Compared with existing technologies, the water-filled fire extinguishing energy storage box of this utility model has a simple structure, low cost, and adopts an immersion fire extinguishing method, which is safe and reliable and will not cause reignition. The water-filled fire extinguishing energy storage box of this utility model is designed as a leak-proof enclosure, with the battery installed at the bottom and the fire sprinkler system installed at the top. Air intake and exhaust fans are installed on the left and right sides of the upper part of the enclosure to cool the battery. The overflow outlet is lower than the fan outlet, and all the boxes are connected together by a water tank connector for unified drainage during use. In the event of an accident, the fire sprinkler head automatically detonates and sprays water to extinguish the fire, filling the box. Once the box is full, the water is discharged from the drain outlet. Immersing the battery in water not only cools the battery but also prevents it from reigniting.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any modifications, equivalent substitutions and improvements made within the concept of the present utility model should be included within the patent protection scope of the present utility model.
