Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging, specifically a water-cooled new energy vehicle charging flame arrestor system. Background Technology

[0002] With the increasing popularity of new energy vehicles, the safety of charging facilities has become increasingly prominent. New energy vehicles are prone to thermal runaway during charging, which can lead to fires and accidents.

[0003] Currently, there are no effective means to directly prevent fire. Fire prevention systems for charging devices on the market primarily focus on the fire ignition of the battery itself, neglecting the charging vehicle. Research on controlling battery fires in new energy vehicles remains at the stage of early warning and the inability to extinguish fires after they start, without linkage with the charging device. There are currently no effective promotional cases for new energy vehicle fire prevention systems, mainly due to the following shortcomings: most large fire prevention devices are liquid-filled, one-time fire prevention devices requiring subsequent refilling; small devices have limited fire prevention effects; water-filled fire prevention and carbon dioxide fire prevention methods cause permanent damage to new energy vehicles; and research on fire prevention for new energy vehicles is not linked to the charging device.

[0004] Therefore, a water-cooled fire arrestor system for charging new energy vehicles is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a water-cooled new energy vehicle charging fire arrestor system to solve the problems mentioned in the background art.

[0008] The pipe assembly is connected to the water storage assembly. The upper end of the pipe assembly is connected to a water curtain nozzle for forming a covering water curtain, and the lower end extends to the outside of the charging device.

[0009] The control component is mounted on the pipe assembly, and a charging gun is provided on the outside of the charging device.

The water-filling pipe is connected to a water tank for adding water to the water tank.

[0012] Preferably, the control component includes solenoid valve one and solenoid valve three, both of which are installed on the water-cooled pipe and are used to control the flow of water inside the water-cooled pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A water-cooled fire arrestor system for charging new energy vehicles, such as Figures 1-4 As shown, it includes a charging device 1, which has a water storage component, a pipe component, and a control component installed inside. The pipe component is connected to the water storage component. The upper end of the pipe component is connected to a water curtain nozzle 11 for forming a covering water curtain, and the lower end extends to the outside of the charging device 1. The control component is installed on the pipe component, and a charging gun 10 is provided on the outside of the charging device 1.

[0026] By controlling the water flow inside the pipe assembly through the control component, the cooling mode or the flame arrestor mode can be switched. In the cooling system mode, water flows inside the pipe assembly and is discharged from the charging device 1. The cooling water absorbs the heat inside the charging device 1 and carries it out of the charging device 1. In the flame arrestor system mode, water is sprayed out through the water curtain nozzle 11 at one end of the pipe assembly to form a covering water curtain to arrest the fire on the vehicle. The flame arrestor effect is good. It is linked with the charging device 1, which solves the heat dissipation problem and integrates the flame arrestor function.

[0027] The lower end of the pipe assembly can also extend into the water tank 2, allowing water to return to the water tank 2 for recycling.

[0028] The control system can actively reduce the internal temperature of the device during daily charging to slow down equipment aging, and can also quickly activate the fire suppression mechanism in the event of a fire to achieve early fire suppression and improve safety redundancy by switching between cooling mode and fire suppression mode.

[0029] The water storage component, pipeline component and control component are integrated inside the charging device 1, which makes high space utilization. Only the charging gun 10 is installed on the outside, which is convenient for installation and maintenance. The water supply of the water storage component can be replenished in a timely manner and is easy to operate.

[0030] The water storage assembly includes a water tank 2 and a pressurized water pump 3. The water tank 2 is installed in the lower part of the charging device 1, and the pressurized water pump 3 is located inside the water tank 2. The outlet of the pressurized water pump 3 is connected to the pipe assembly.

[0031] The water pump is used to pressurize the water so that in the cooling mode, the cooling water flows through the pipe assembly, and in the flame arrestor mode, the water is sprayed out through the water curtain nozzle 11 to form a water curtain of a certain area to cover the vehicle.

[0032] The piping assembly includes a water-cooled pipe 4 and a water-filling pipe 5. One end of the water-cooled pipe 4 is connected to the outlet of the pressurized water pump 3. The middle part of the water-cooled pipe 4 is coiled inside the charging device 1, and the end of the water-cooled pipe 4 extends to the bottom of the charging device 1 for cooling water discharge. The water-filling pipe 5 is connected to the water tank 2 for adding water to the water tank 2.

[0033] By using the spiral arrangement of water-cooled pipes 4 in conjunction with the pressurized water pump 3, the circulating cooling of key components inside the charging device 1 is enhanced, avoiding local overheating and reducing the risk of thermal runaway.

[0034] Water supply pipe 5 promptly fills water tank 2 with water. Water in water cooling pipe 4 absorbs heat from charging device 1 and is then discharged from charging device 1 through one end of water cooling pipe 4.

[0035] The control components include solenoid valve 6 and solenoid valve 9, both of which are installed on the water cooling pipe 4 and are used to control the flow of water inside the water cooling pipe 4.

[0036] The control components also include solenoid valve 2 7, and two sets of flame arrestor pipes 8 are connected and fixed in the middle of the water cooling pipe 4. Solenoid valve 2 7 is installed on both sets of flame arrestor pipes 8, and the flame arrestor pipes 8 are located between solenoid valve 1 6 and solenoid valve 3 9.

[0037] The charging device 1 is water-cooled, and the lower internal space can be reserved for a spare water tank 2. The water cooling pipe 4 consists of one or more pipes, which are used to remove the heat from the charging device 1 during normal operation. The water curtain nozzle 11 has an adjustable structure, and the water curtain coverage area can be manually adjusted.

[0038] Cooling mode: Solenoid valve 6 and solenoid valve 9 are open, solenoid valve 7 is closed, and water flows through the cooling pipes to absorb heat.

[0039] Flame arrestor mode: Solenoid valve 16 is closed, solenoid valve 39 and two sets of solenoid valves 27 are open, water enters the flame arrestor pipe 8 through the cooling pipe, and forms a water shield through the water curtain nozzle 11 to arrest the flame of the vehicle.

[0040] The control components also include at least one of relays, contactors, and time relays for controlling the operation of devices within the charging device 1.

[0041] Figure 2 In the diagram, DCF is a solenoid valve, K, KT, and KA are relays, KM is a contactor, and SJ is a time relay. The relays, contactors, and time relays are all existing technologies, and their specific connections and uses will not be described in detail.

[0042] The fire-arresting system of the water-cooled new energy vehicle charging device 1 integrates cooling and fire-arresting modes by utilizing the water-cooled charging device 1 as the main structure. It contains a pressurized water pump 3, an adjustable water curtain nozzle 11, and a solenoid valve. Water resources can be reused, and the fire-arresting state is effective for a long time. False alarms will not cause permanent damage to the new energy vehicle. For the charging device 1 manufacturer, it not only solves the heat dissipation problem but also integrates the fire-arresting function, improving the degree of automation and adding power. For new energy vehicle users, it increases safety during the charging process, preventing the expansion of losses in the event of thermal runaway or false alarms.

[0043] The working principle of the water-cooled new energy vehicle charging flame arrestor system provided by this utility model is as follows:

[0044] In cooling mode, solenoid valve 6 and solenoid valve 9 are open, and solenoid valve 7 is closed, allowing water to flow through the cooling pipes and absorb heat. In flame arrestor mode, solenoid valve 6 is closed, and solenoid valve 9 and two sets of solenoid valves 7 are open, allowing water to enter the flame arrestor pipe 8 through the cooling pipes and form a water shield through the water curtain nozzles 11 to arrest the flame of the vehicle.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
