Description

一种矿用自卸车混合动力系统
技术领域
本发明涉及工程机械动力系统，具体是一种矿用自卸车混合动力系统。
背景技术
矿用自卸车广泛应用于矿山、大型建筑等领域，但自卸车大型柴油机油耗惊人。根据具体载重吨位的不同，油箱容积大约为千余升到数千升，每年耗油量折算达数百万元。据统计，运输成本约占矿石成本的45%~55%，车辆能源消耗约占矿石总能耗的40%~60%，也造成极大的大气污染物排放。混合动力自卸车将是未来一段时间重点应用的技术，即可响应节能减排发展趋势，又能保证动力的需求。
现有自卸车大多为液力传动，存在的不足是：
1、设备空间大、维护时间长且当发电机损坏后车辆无法运行，容易半路搁浅，不便维修；
2、在北方领域气温较低，矿车交接班期间若出现24V蓄电池馈电，导致车辆无法启动，严重影响车辆运行。
发明内容
为解决上述技术问题，本发明提供一种矿用自卸车混合动力系统。
本发明通过以下技术方案实现：一种矿用自卸车混合动力系统，包括发电机和24V蓄电池，所述发电机控制连接牵引电机；所述发电机连接整流模块；所述整流模块连接逆变模块，整流模块至逆变模块的电路中连接有储能蓄电池；所述逆变模块连接所述牵引电机；岸电充电接口连接有滤波器，滤波器连接所述整流模块。
其进一步是：所述发电机至整流模块的电路中连接有开关K1。
所述滤波器至整流模块的电路中连接有开关K2。
还包括光伏电池板，光伏电池板输出端连接有24V备用蓄电池；所述24V备用蓄电池连接至所述24V蓄电池。
所述24V备用蓄电池至24V蓄电池的电路中连接有开关K3。
与现有技术相比，本发明的有益效果是：
1、可以回收牵引电机制动时的能量并利用，充分利用牵引电机制动能量给储能蓄电池充电，牵引时可以充分利用储能蓄电池能量提供动力，减少碳排放；
2、当发电机出现异常时，能通过储能蓄电池的能量使车辆能尽快运行到检修库，无需其他车牵引；
3、利用司机交接班时间，K1断开、K2闭合接入充电三相电源，为储能系统充电，滤波器用于网侧谐波抑制，保证电能质量满足要求；
4、当气温较低，矿车交接班期间出现24V蓄电池馈电情况，导致车辆无法启动时，可以通过光伏电池板避免此类问题产生。

结合图1所示，一种矿用自卸车混合动力系统，包括发电机4、24V蓄电池2，发电机4提供整车动力，24V蓄电池2为整车提供24V电源。发电机4电连接整流模块5，整流模块5将三相交流电转换成直流电。发电机4至整流模块5的电路中安装开关K1。整流模块5电连接逆变模块6，逆变模块6电连接牵引电机8。逆变模块6将整流出的直流电变成频率、幅值可调的交流电，驱动牵引电机8，进而驱动整车运行。整流模块5至逆变模块6的电路中电连接储能蓄电池7，储能蓄电池7连接在直流侧，用于吸收牵引电机8制动能量。
岸电充电接口连接滤波器1，滤波器1电连接整流模块5，滤波器1用于网侧谐波抑制。当司机交接班时，可以利用岸电充电接口给储能蓄电池7充电。
光伏电池板3输出端电连接24V备用蓄电池，24V备用蓄电池电连接至24V蓄电池2。24V备用蓄电池至24V蓄电池2的电路中安装开关K3。
工作方式：
正常运行况时：发电机4输出的交流电，经整流模块5后变成直流电，经过逆变模块6后，逆变成三相交流电，输出给牵引电机，用来驱动牵引电机8；储能蓄电池7和发电机4按照系统功率分配提供相应的动力。当牵引电机8制动时，能量给储能蓄电池7充电；
在司机交接班期间，断开K1、闭合K2，通过岸电充电接口、经滤波器1抑制谐波、整流模块5给储能蓄电池7充电，滤波器用于网侧谐波抑制，保证电能质量满足要求；
