[0002] As the number of new energy vehicles increases, more and more charging stations are being built for them. Most new energy vehicles are equipped with lithium batteries, which are highly susceptible to fire and are a major cause of fires at new energy high-voltage charging stations. The charging room contains numerous charging devices, many of which are high-power and high-current, which can easily cause circuit overheating and fires.
[0003] Moreover, extinguishing a fire caused by a new energy battery is different from extinguishing a conventional fire. The fire frequency is very high and requires continuous watering to control the fire. Therefore, different requirements are put forward for conventional fire pumps and fire motors, requiring a higher waterproof grade. In addition, the frequency of replacement and maintenance of fire pumps will increase during use. Therefore, we need fire pumps that are easier to replace and repair to reduce the maintenance burden during use.
[0004] To this end, the utility model provides a fire pump which is highly waterproof and easy to disassemble and replace. Utility Model Content

One end of the split rubber head 62 is screwed into the rubber bushing 61. The gasket 52 is sleeved on the wiring cable 6 between the compression nut 51 and the split rubber head 62. The integrated rubber head of the traditional fire pump motor cable is designed as a split rubber head 62. , with the use of the rubber bushing 61, the split rubber head 62 can be directly sleeved on one end of the wiring cable 6, and then passed through the clamping nut 51 to fix it with the rubber bushing 61. After the fixation is completed, the sealing between the clamping nut 51 and the wiring cable 6 can be ensured. Secondly, when the clamping nut 51 is screwed into the wiring port 5, the split rubber head 62 is located in the wiring port 5, which can also improve the anti-leakage performance of the wiring port 5. In addition, the design of the split rubber head 62 allows you to directly replace the split rubber head 62 when the rubber head is damaged and water seepage occurs, without having to replace the entire wiring cable 6. This not only saves cost and time, but also is more conducive to later maintenance and replacement.
