The invention discloses a movable arm potential energy recovery system of a movable arm independent drive type hydraulic excavator. The movable arm potential energy recovery system comprises a main oil way module, a transmission module, an energy supply module, a three-cavity hydraulic cylinder energy recovery module, a flow regeneration energy recovery module and a temperature control module. The descending potential energy of the movable arm is recovered through the three-cavity hydraulic cylinder energy recovery module and the flow regeneration energy recovery module, the flow regeneration energy recovery module comprises a mechanical transmission structure, the auxiliary hydraulic pump is driven by rodless cavity oil pressure to store energy, reverse utilization can be achieved, and the energy recovery rate is high. And the temperature control module can monitor the temperature of hydraulic oil in each energy recovery loop in real time and adjust the temperature, so that the system is prevented from being influenced by too high oil temperature. The problems that a hydraulic excavator is low in energy utilization rate and large in power consumption are solved, and the temperature control problem which is not considered in other energy recovery systems is considered.

本发明公开了一种动臂独立驱动式液压挖掘机动臂势能回收系统，包括主油路模块、传动模块、供能模块、三腔液压缸能量回收模块、流量再生能量回收模块与温控模块；本发明通过三腔液压缸能量回收模块与流量再生能量回收模块回收动臂下降势能，其中流量再生能量回收模块包括一种机械传动结构，用无杆腔油压带动副液压泵进行储能，并可以反向利用，能量回收率较高。温控模块能够实时监测各能量回收回路中液压油的温度，并进行调节，防止油温过高对系统造成影响。本发明既解决了液压挖掘机能量利用率较低，功耗大的问题又考虑了其他能量回收系统中没有考虑的温控问题。
