具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参阅图1至图4，本发明一实施例中的动力设备10，至少能够提高压缩效率，且避免动力设备10的体积设置的过大。
具体地，动力设备10包括动力源100、往复组件200及压缩组件300，往复组件200包括动力轴210及往复件220，动力轴210与往复件220传动配合；动力源100用于驱动动力轴210带动往复件220沿动力轴210的轴线方向往复移动。压缩组件300包括压缩缸体310及活塞320，压缩缸体310内形成有第一压缩腔330及第二压缩腔340，第二压缩腔340的体积小于第一压缩腔330，且压缩缸体310的外壁上形成有与第一压缩腔330连通的第一通道350及与第二压缩腔340连通的第二通道360；活塞320包括第一塞体321及与所述第一塞体321相连接的第二塞体322，第一塞体321设置于第一压缩腔330内，第二塞体322设置于第二压缩腔340内；压缩组件300的活塞320连接于往复件220，往复件220能够带动活塞320往复移动。
在本实施例中，动力设备10作为压缩机或充气泵使用时，压缩物质能够从所述第一通道350吸入第一压缩腔330内并压缩至第二压缩腔340内，由第二通道360排出。在另一实施例中，动力设备10作为真空泵等使用时，气体由第二通道360吸入并由第一通道350排出。
一实施例中，当动力设备10作为压缩机使用时，动力源100驱动动力源100带动往复件220沿动力轴210的轴线方向往复移动，进一步带动活塞320沿动力轴210的轴线往复移动。由于第一塞体321设置于第一压缩腔330内，第二塞体322设置于第二压缩腔340内，例如当活塞320朝朝向往复件220的方向移动时，第一塞体321将第一压缩腔330内的气体压缩至第二压缩腔340内，当活塞320朝远离往复件220的方向移动时，第二塞体322压缩第二压缩腔340内的气体介质通过第二通道360排出，此时气体通过第一通道350进入到第一压缩腔330内。依此往复循环，实现气体的二级压缩。进而当活塞320朝朝向往复件220的方向移动时，实现的是一级压缩，二级进气，当活塞320朝远离往复件220的方向移动时，实现二级压缩，一级进气，进而不仅实现气体的二级压缩，同时压缩效率更高。
在本实施例中，往复组件200的数量为两个，动力源100用于驱动两个动力轴210分别带动往复件220沿动力轴210的轴线方向往复移动；压缩组件300的数量为两个，两个压缩组件300的活塞320分别连接于两个往复件220，单个往复件220能够带动与之连接的活塞320往复移动。由于压缩组件300与往复组件200均为两个，两个往复组件200的动力轴210均通过动力源100驱动，进而实现两个压缩组件300的同步压缩，提高压缩效率，且通过一个动力源100实现双侧的二级压缩，压缩效率更高，动力设备10的体积更 小。

在其他实施例中，两个往复组件200还可以布置于动力源100的同一侧，或者根据设计要求呈其他方式布置，两个动力轴210通过传动组件连接于动力源100。
一实施例中，动力设备10还包括连接通道410，连接通道410的一端与一压缩组件300的第一通道350连通，另一端与另一压缩组件300的第二通道360连通。由于在本实施例中，一个压缩组件300实现二级压缩，通过连接通道410使得一侧的压缩组件300经过二级压缩后的气体由第二通道360排出至另一侧的压缩组件300的第一通道350，另一侧的压缩组件300对经过二级压缩后的气体再次进行二级压缩，进而实现气体的四级压缩，压缩效率更高。
在本年实施例中，动力设备10还包括连接管420，连接管420内形成有连接通道410，连接管420的一端连接于一压缩组件300的第一通道350处，另一端连接于另一压缩组件300的第二通道360处。通过连接管420以使一压缩组件300的第二通道360通过连接通道410与另一压缩组件300的第一通道350连通。
在其他实施例中，动力设备10还可以包括壳体，连接通道410通过在壳体的内壁形成凹槽的方式形成。或在另一实施例中，连接通道410还可以通过其他方式形成，只要能够便于实现一压缩组件300的第一通道350与另一压缩组件300的第二通道360的连通即可。

在其他实施例中，压缩缸体310上开设有与第二压缩腔340连通的第一导向孔316，导杆221的一端穿过第一导向孔316并穿设于第二压缩腔340内与第二塞体322相连接。
在本实施例中，往复套222的外壁上设置有限位套223，导杆221穿设并限位于限位套223内。通过设置限位套223便于实现导杆221与往复套222的连接。在其他实施例中，导杆221还可以一体成型于往复套222上。
一实施例中，导杆221的数量为至少两个，各个导杆221绕动力轴210的轴线均匀布置于往复套222的外壁上，第一导向孔316的数量与导杆221的数量相一致，每一导杆221对应穿过一第一导向孔316并与活塞320连接。通过设置至少两个导杆221与活塞320连接，能够提高驱动活塞320往复移动的可靠性。在本实施例中，导杆221的数量为两个，两个导杆221均匀间隔设置于往复套222的外壁上，在其他实施例中，导杆221的数量还可以为一个或三个等其他数目个。
一实施例中，动力轴210上设置有往复导轨，往复导轨的轨迹为环绕动力轴210轴线的闭合曲线，且所述往复导轨的波峰与波谷沿动力轴210的轴线间隔设置；往复件220还包括限位体224，限位体224定位于往复套222的内壁上并与往复导轨导向配合，限位体224能够在往复导轨上沿着往复导轨的轨迹移动。在本实施例中，往复导轨为往复槽230，往复槽230的轨迹为环绕动力轴210轴线的闭合曲线，限位体224穿设于往复槽230内， 限位体224能够在往复槽230沿着往复槽230的轨迹移动。
动力轴210转动时，限位体224能够在往复槽230内移动，使得限位体224能够在呈曲线形槽的波峰与波谷之间的运动，以实现限位体224带动往复套222沿着动力轴210的轴线方向往复移动的目的，进而通过导杆221带动活塞320沿着动力轴210的轴线方向往复移动。动力轴210的旋转运动转化为往复套222及导杆221的沿动力轴210轴线的直线运动，不会出现曲柄结构或偏心驱动结构的偏摆交问题，做功稳定性更好。
一实施例中，动力轴210包括传动套211及传动轴212，传动套211套设于传动轴212上，且往复槽230开设于传动套211的外壁上；压缩缸体310朝向对应连接的往复套222的一侧开设有转动孔317，传动轴212的一端穿设于转动孔317内，另一端连接于动力源100。通过将往复槽230开设于传动套211上，能够保证传动轴212的结构完整，进而保证传动轴212传递转动的稳定。且由于传动轴212进一步穿设于压缩缸体310的转动孔317，通过转动孔317不仅能够支撑传动轴212，保证传动轴212的转动稳定性。
另一实施例中，往复导轨还可以为导向凸起，导向凸起的轨迹为环绕动力轴210轴线的闭合条状曲线，限位体224设置于导向凸起上并能够在导向凸起上沿长度方向移动。
一实施例中，往复导轨为至少两个，各个往复导轨沿着动力轴210的轴线间隔设置，每一往复导轨上均设置有至少一限位体224。通过设置至少两个往复导轨，能够提高通过往复套222及导杆221带动活塞320移动的稳定性。

具体地，平衡体设置于限位体224朝向动力源100的一侧。进一步地，平衡导轨与往复导轨的结构一致，平衡导轨相对于往复导轨沿动力轴210的周线对称设置。在本实施例中，平衡体与限位体224结构一致。

一实施例中，限位体224为球体，限位体224能够在往复槽230内滚动。通过将限位体224设置为球体，能够降低限位体224在移动时的摩擦力。
一实施例中，往复槽230的内壁上开设有导油槽232。导油槽232内可以设置润滑油，进而限位体224在往复槽230内移动时，利用润滑油进一步降低摩擦阻力，保证传动的顺畅。
具体地，导油槽232为环绕动力轴210轴线的闭合曲线形槽。由于导油槽232设置于往复槽230的内壁上，进而使得导油槽232的轨迹与往复槽230的轨迹一致，保证了限位体224移动至往复槽230内任一处均有润滑油。
参阅图2至图4，一实施例中，往复组件200还包括保护壳240，动力轴210及往复件220均位于保护壳240内，且保护壳240的内壁上开设有与第一导向孔316相对设置的第二导向孔241，导杆221背向于第一塞体321的一端穿设于第二导向孔241内，且导杆221能够在第二导向孔241内移动。通过在保护壳240内设置第二导向孔241，能够进一步保证导杆221移动的稳定性，进一步保证活塞320往复移动的稳定性。且通过保护壳240还能够进一步保证动力轴210与往复件220，保证动力轴210与往复件220之间的传动稳定性。
具体地，压缩缸体310朝向往复件220的一侧形成有拼接腔318，保护壳240朝向压缩缸体310的一侧开口，保护壳240内形成有润滑油腔242，保护壳240的开口侧与压缩缸体310对接连接，以使拼接腔318与润滑油腔242对应连通，动力轴210及往复件220位于拼接腔318与润滑油腔242连通后的空间内。在安装时，以使动力轴210与往复件220设置于保护壳240与压缩缸体310之间，提高的安装便利性，且保证保护壳240与进气件315之间的稳定连接。
在本实施例中，进气件315背向于第一缸本体311的一侧形成拼接腔318，保护壳240与进气件315相连接。在另一实施例中，可以为排气件314背向于第二缸本体312的一侧形成拼接腔318，保护壳240与排气件314相连接。

一实施例中，储能系统还包括回热器，所述回热器连接于所述透平机及所述动力设备10。动力设备10压缩空气过程中会释放热量，热量可通过回热器收集起来，待到释放压缩空气发电时使用，透平机发电过程中需要吸收热量，从而整体达到更高的能源转换效率。
