Description
技术领域
本发明属于充换电领域,特别涉及一种水浸式灭火换电充电柜***及其灭火方法。
背景技术
现有的锂电池换电柜/充电柜普遍使用气溶胶灭火器或者七氟丙烷灭火器,该类灭火剂的主要工作原理是通过隔绝空气中的氧气,从而使得燃烧反应无法进行,但是在锂离子电池内部正极材料,特别是在充电状态下的正极材料本身就是一种强氧化剂,而负极活性物质、电解液等都是还原剂,已经具备了基本的燃烧条件,因此普通的隔绝空气型灭火剂就对锂离子电池火灾起到效果。
还有的换电柜采用水喷淋灭火的方式,但单这种方式由于水喷淋的速度和喷淋的范围有限,不能完全有效的进行灭火,或者水喷淋过程没法有效的降温,使得电池复燃的几率很大。

所述主水管道12的上下端两端分别设置有上截止阀19和下截止阀18,能够便于对管路进行检修。
所述充电柜本体1中的若干格口呈左右两列设置,且两列格口之间包含容纳腔15,所述主水管道12设置在所述容纳腔内,整体结构更加紧凑。
所述电池仓4的外侧壁上设置有锁具16,锁具为电控锁,如电磁锁等,所述仓门3对应于锁具16设置有锁舌17,用于封闭放置口,使得电池仓形成周向分别的盒体结构。
所述电池仓4的仓底壁为波浪形截面的板体结构,当电池本体放入在电池仓4内部时,仓体内底部能够形成多个存水通道,能够保证对电池本体10的底部进行降温和灭火。
如附图8至附图11所示,所述电池仓(4)背离于格口的一侧壁上开设有排水孔30,所述电池仓4的外部对应于排水孔30设置有延时排水机构,所述电池仓内存集的水溶液通过延时排水机构逐渐排出;在灭火初期时,电池仓内正常存水灭火,在灭火后,通过延时排水机构进行一断时间的延时,延后将电池仓内的水溶液排出,从而便于后序取出电池仓。

电池仓内的水溶液通过渗水通道42缓慢的渗入到集水筒37中,集水筒内流入的液体通过堵头的封堵而使得排水管31的管路截止;
电池仓内的水溶液持续向集水筒内渗入,集水筒内液面升高使得浮子34上浮,当浮子向上浮动并拉动堵头36从集水筒37的出水口脱离时,则排水管31的管路被导通,电池仓内的水溶液从排水管向充电柜本体外部排出。
所述集水筒37底部的出水端设置有磁吸环38,所述磁吸环38与集水筒37同轴设置,所述堵头36为磁性材质,所述堵头36在浮子的升降切换中脱离或吸附在磁吸环上;在所述堵头吸附在磁吸环的状态下,所述排水管的管路被截止。通过磁吸结构能够保证堵头在集水筒底部的出水端时,能够稳定的对水路进行截止,保证水溶液在电池仓内的存留时间。同时,环形的磁吸结构也能保证堵头密封贴合在出水端上。

所述充电柜本体1上设置有固定板51,所述排水管31对应于电池仓的一端为L型弯管结构,所述排水管31的横臂管体活动穿设在固定板51上,且所述排水管31的横臂管体上套设有复位弹簧43,所述排水管的横臂管体通过复位弹簧连接于固定板上,所述排水管的横臂管体相对于电池仓4有一定程度的弹性位移,当电池仓放置在格口内时,电池仓的壁体能够弹性的抵压在排水管的进水端上,通过弹性位移能够保证排水管与电池仓接触后密封,防止电池仓向排水管外部渗水。
一种水浸式灭火换电充电柜***的灭火方法,包括:当电池仓内电池起火后,集水箱向对应的电池仓通入水溶液,并使得水溶液浸没电池而进行灭火;
在灭火过程中和灭火后,电池仓内的水溶液通过渗水通道42缓慢的渗入到集水筒37中,集水筒内流入的液体通过堵头的封堵而使得排水管31的管路截止;
电池仓内的水溶液持续向集水筒内渗入,集水筒内液面升高使得浮子34上浮,当浮子向上浮动并拉动堵头36从集水筒37的出水口脱离时,则排水管31的管路被导通,电池仓内的水溶液从排水管向充电柜本体外部排出;
在堵头被上提后且浮子34继续上浮的过程中,浮子顶升伸缩杆41并使得伸缩杆朝向排水孔的一侧位移,使得渗水球头移出至排水管的进水端,渗水通道的截面积增大,从电池仓进入到排水管中的水流量增大,则排水管进行快速排水。
以上所述仅是本发明的优选实施方式,应当指出:对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
