[0048] The working principle of the present utility model is as follows: When a new energy vehicle is parked in parking space A1, the top spray fire-fighting component 32 and the ground spray fire-fighting component 31 of the parking fire-fighting device 3 corresponding to this parking space A1 are respectively located on the upper and lower sides of the new energy vehicle. When a new energy vehicle parked in a certain parking space A1 has a fire problem (such as smoking or even an open flame), at this time, the master controller 1 detects through the fire detection device 33 of the parking fire-fighting device 3 corresponding to this parking space A1 that the new energy vehicle parked in this parking space A1 has a fire problem. Then, the master controller 1 controls the top spray solenoid valve 323 of the top spray fire-fighting component 32 and the ground spray solenoid valve 313 of the ground spray fire-fighting component 31 of the parking fire-fighting device 3 corresponding to this parking space A1 to open.

Among them, on the one hand, the top spray nozzles 321 of the top spray fire-fighting component 32 of the parking fire-fighting device 3 spray water on the upper side of the new energy vehicle with a fire problem, which can make the smoke and dust generated by the fire settle and cool down, reduce the harm caused by the smoke and dust, and the water flow sprayed by the top spray nozzles 321 can also adhere to the new energy vehicle to reduce the spread of the fire, further ensuring fire safety; on the other hand, the ground spray nozzles 311 of the ground spray fire-fighting component 31 of the parking fire-fighting device 3 spray water on the bottom of the new energy vehicle with a fire problem, which can effectively reduce the temperature of the power battery of the new energy vehicle to ensure effective fire extinguishing of the power battery; combining these two aspects, the present utility model can effectively extinguish the fire of the new energy vehicle and ensure fire safety.

[0049] In the first embodiment of the present utility model, the fire detection device 33 of the parking fire protection device 3 includes a temperature and smoke fire detector 331, a flame detector 332, and an infrared temperature detector 333. The temperature and smoke fire detector 331, the flame detector 332, and the infrared temperature detector 333 can all detect whether a new energy vehicle catches fire. The flame detector 332 and the infrared temperature detector 333 can be arranged adjacent to the parking space A1, and the temperature and smoke fire detector 331 is arranged above the parking space A1. The parking area A can be provided with a shed A3 to shade and protect the new energy vehicle from rain. The temperature and smoke fire detector 331 and the parking fire protection device 3 can be arranged on the ceiling A31 of the shed A3. The parking area A can be provided with a charging pile A4 to charge the new energy vehicle. The charging pile A4 is electrically connected to the main controller 1. When the main controller 1 detects that a new energy vehicle catches fire through the fire detection device 33, the main controller 1 controls the charging pile A4 to cut off the power supply to ensure safety.

[0050] In the first embodiment of the present utility model, a parking fire protection system for a new energy vehicle of the present utility model further includes a water recovery device 4 that cooperates with the water supply tank 21. The water recovery device 4 is used to recover the water sprayed by the ground spray fire protection component 31 and the ceiling spray fire protection component 32 to the water supply tank 21, effectively saving water resources. At the same time, it can also effectively extend the spraying time of the ground spray fire protection component 31 and the ceiling spray fire protection component 32 to ensure the fire extinguishing effect.

[0051] In the first embodiment of the present utility model, a water collection trench A2 is provided in the parking area A for collecting the water flows ejected by the ground spray fire-fighting component 31 and the ceiling spray fire-fighting component 32; and the water recovery device 4 includes a recovery water tank 41 and a recovery water pump 42. The recovery water tank 41 is communicated with the water collection trench A2 so that the water flow collected by the water collection trench A2 can flow into the recovery water tank 41. The water inlet of the recovery water pump 42 is communicated with the recovery water tank 41, and the water outlet of the recovery water pump 42 is communicated with the water supply water tank 21. The recovery water pump 42 is electrically connected to the main controller 1. After the ground spray fire-fighting component 31 and the ceiling spray fire-fighting component 32 spray water for a period of time and the recovery water tank 41 can collect a certain amount of water flow, the main controller 1 controls the recovery water pump 42 to operate, so that the recovery water pump 42 pumps the water flow in the recovery water tank 41 into the water supply water tank 21 to replenish water to the water supply water tank 21. Among them, each parking space A1 in the parking area A is provided with a drainage trench A11 communicated with the water collection trench A2, so that the water flows ejected by the ground spray fire-fighting component 31 and the ceiling spray fire-fighting component 32 can be effectively collected into the water collection trench A2; a filter plate A5 is arranged at the connection between the water collection trench A2 and the recovery water tank 41 to prevent impurities from entering the recovery water tank 41. Specifically, the upper part of the filter plate A5 is a hollow structure, and the lower part of the filter plate A5 is a closed structure; and a drainage solenoid valve A21 is arranged in the water collection trench A2, and the drainage solenoid valve A21 is electrically connected to the main controller 1. In the normal state, the drainage solenoid valve A21 is opened, so that the water flow (generally rainwater) in the water collection trench A2 is discharged from the drainage solenoid valve A21; and when the ground spray fire-fighting component 31 and the ceiling spray fire-fighting component 32 eject water due to a fire problem, the main controller 1 controls the drainage solenoid valve A21 to close, so that the water collection trench A2 can collect the water flows ejected by the ground spray fire-fighting component 31 and the ceiling spray fire-fighting component 32. When the water flow in the water collection trench A2 exceeds the closed part of the lower part of the filter plate A5, the water flow in the water collection trench A2 is filtered through the hollow part of the upper part of the filter plate A5 and then flows into the recovery water tank 41.

[0052] In the first embodiment of the present utility model, the ground spray nozzles 311 and the ground spray pipelines 312 of the ground spray fire-fighting component 31 of each parking fire-fighting device 3 are arranged in the drainage trench A11 of the parking space A1 corresponding to the parking fire-fighting device 3, so as to prevent new energy vehicles from pressing on the ground spray nozzles 311 and the ground spray pipelines 312 of the ground spray fire-fighting component 31 and effectively protect the ground spray nozzles 311 and the ground spray pipelines 312 of the ground spray fire-fighting component 31.

When the present utility model is in a normal state, the water flow in the ground spray fire-fighting component 31 and the top spray fire-fighting component 32 of each parking fire-fighting device 3 is drained and the water supply solenoid valve 23 is closed, thereby preventing the problem of the water flow inside the ground spray fire-fighting component 31 and the top spray fire-fighting component 32 of the parking fire-fighting device 3 from freezing in winter. And the thermal insulation equipment box 5 can provide thermal insulation for the water supply tank 21 in winter to prevent the water flow in the water supply tank 21 from freezing in winter. In this way, the present utility model can ensure the normal use of the present utility model in winter. When the main controller 1 controls the water supply pump 22 to work, the main controller 1 also controls the water supply solenoid valve 23 to open to ensure that the water flow can be normally delivered to the ground spray fire-fighting component 31 and the top spray fire-fighting component 32.

[0054] In the first embodiment of the present utility model, a temperature control heater 6 is provided in the thermal insulation equipment box 5. The temperature control heater 6 is electrically connected to the main controller 1. In winter, the main controller 1 can control the temperature control heater 6 to work to effectively increase the internal temperature of the thermal insulation equipment box 5 and ensure that the water flow in the water supply tank 21 will not freeze in winter.
