These reactions create conditions for battery explosion. In order to improve the safety of battery use and reduce the possibility of battery explosion accidents, we propose a marine battery.

[0025] Preferably, Figure 2 As shown, a bearing is installed at the connection between the rotating shaft 5 and the battery shell 1, and the blades 6 are curved insulating thin plates arranged in a linear array with equal intervals. The areas of adjacent blades 6 increase or decrease in a step-like manner in the linear direction. By continuously generating gas, work can be done on the blades 6 to cause the blades 6 to rotate.

[0026] Preferably, Figure 2As shown, the uniform magnetic pole 8 includes two magnetic poles of opposite names. The uniform magnetic pole 8 generates a uniform magnetic field.

[0028] Working principle: When in use, when the chemical battery component 2 in the battery shell 1 undergoes a chemical reaction to generate current, if the chemical battery component 2 works abnormally, gas will be generated in the electrolyte. The thrust generated by the gas within the normal dosage range is not enough to drive the blades 6 and the shaft 5 to rotate. When the chemical battery component 2 stops reacting, the temperature drops and the safe state can be entered. When the reaction process of the chemical battery component 2 is abnormal, as the gas increases and the gas pressure in the battery shell 1 increases, the generated gas causes the blades 6 to rotate around the center line of the shaft 5. When the blades 6 drive the shaft 5 to rotate, the shaft 5 can further pull the coil 7 to rotate in the vertical direction. The coil 7 rotates between the uniform magnetic poles 8 to cut the magnetic field generated by the uniform magnetic poles 8, so that the magnetic flux passing through the coil 7 changes, thereby generating an induced electromotive force and an induced current in the coil 7 and connecting the alarm indication structure circuit, so that the maintenance personnel can detect the abnormal state of the battery in time, so as to carry out maintenance in time and avoid explosion accidents. By setting a combined pressure relief structure, the gas pressure in the battery shell 1 can be quickly released. During the pressure relief process, the change in the reading of the air pressure gauge 12 can provide a reference for whether to open the emergency manual exhaust cover 4, which is beneficial for the maintenance personnel to correctly judge the size of the gas pressure in the battery shell 1.
