And in order to prevent rain and snow from entering the above-mentioned intake pipe 11, an umbrella cap can be set on the above-mentioned filter screen 7.
为了减小上述气囊14的制造难度和更换难度，具体的，上述第一凹槽13为多个，上述气囊14为多个，上述进气管道11为多个，上述出气管道12；上述第一凹槽13和上述气囊14一一相对。在单位面积内使用的上述凹槽和上述气囊14数量越多，上述凹槽和上述气囊14的体积越小，使得上述气囊14的制造难度和维护更换时的难度减小。In order to reduce the difficulty of manufacture and replacement of the airbag 14, specifically, there are multiple first grooves 13, multiple airbags 14, multiple air intake ducts 11, air outlet ducts 12; The groove 13 is opposite to the above-mentioned air bag 14 one by one. The more the grooves and the airbags 14 used per unit area, the smaller the volume of the grooves and the airbags 14 , which reduces the difficulty of manufacturing and maintenance and replacement of the airbags 14 .
如图3所示，由于车速影响了上述出气管道12流速，为了防止对上述风扇43造成过大的冲击，具体的，上述出气管道12和上述发电机之间设有储气罐8。上述储气罐8能够有效的进行缓冲，延长上述风扇43的使用寿命。由于道路车辆通行时间不定，为防止无车辆通行时上述上述蓄电池6、氢气存量用完，使得上述用电设备、上述发动机被迫停止工作，上述储气罐8能够提供空气，延长上述用电设备、上述发动机的工作时间。上述储气罐8可以设置多个，并将车辆的行驶速度分为多级，每一级对应一个速度范围，即对应气体流速，每一级对应一个上述储气罐8，并将不同的上述储气罐8的出气管口直径设为不同，使得不论车辆经过速度是快是慢，均能够向上述风扇43稳定的供气。As shown in FIG. 3 , since the vehicle speed affects the flow rate of the air outlet pipe 12 , in order to prevent excessive impact on the fan 43 , specifically, an air storage tank 8 is provided between the air outlet pipe 12 and the generator. The air storage tank 8 can effectively buffer and prolong the service life of the fan 43 .
