The invention discloses a horizontally-distributed hydraulic energy storage device arranged inside an excavator working mechanism. The horizontally-distributed hydraulic energy storage device comprises a movable arm, a movable arm oil cylinder, a bucket rod oil cylinder, a bucket rod, a bucket oil cylinder, a bucket and three piston type energy accumulators. According to the horizontally-distributed hydraulic energy storage device, energy recovered by a hydraulic loop can be stored in the energy accumulators which are connected through threads and fixed in the movable arm and the bucket rod in a horizontally distributed mode, energy storage and release of each energy accumulator are controlled through a wireless data receiver so as to solve the problem that the space of an upper vehicle part of an excavator is small, and the energy storage path is too long, and achieve the space-saving effect.

本发明公开一种挖掘机工作机构内置水平分布式液压储能装置，包括动臂、动臂油缸、斗杆油缸、斗杆、铲斗油缸、铲斗以及三个活塞式蓄能器。本发明能够将液压回路回收的能量储存到通过螺纹联接并水平分布式固定在动臂、斗杆内部的蓄能器中，并且通过无线数据接收器控制每个蓄能器能量的储存与释放，以解决挖机上车部分空间少、储能路径太长等问题，达到节省空间的作用。
