介质板2的具体形状和尺寸可以根据罐体1的形状和尺寸进行确定，示例的，罐体1为内设空腔的圆柱型结构，介质板2则为实心的圆盘型结构，介质板2沿罐体1的轴向移动。
在介质板2移动过程中，第一缝隙15用于熔盐液或空气的流动，避免介质板2对空气或熔盐液造成挤压问题，第一缝隙15的具体尺寸可以根据实际需要进行设置，对此不作限制。
储热材料是用于储存热量的材料，储热材料的具体类型可以根据实际需要进行设置，示例的，储热材料可以是混凝土、耐火镁砖、氧化锂与氧化铝等高温烧结成型的混合材料等。
伴热是指对熔盐液进行加热，以使熔盐液的温度保持恒定。
如图1和图2所示，在一些实施例中，熔盐储罐还包括熔盐泵5，熔盐泵5设置在罐体1上，熔盐泵5的进液端浸入熔盐液并靠近罐体1的底部，介质板2套设在熔盐泵5的进液端上，且介质板2的内壁与熔盐泵5进液端的外壁之间设置有第二缝隙16；
其中，驱动装置4驱动介质板2浸入熔盐液并靠近罐体1的底部，以使介质板2加热并排挤熔盐泵5进液端的熔盐液。
可以理解的是，熔盐泵5用于多个熔盐储罐之间的熔盐液循环，在罐体1中的熔盐液未参与换热时，熔盐泵5关闭，此时通过介质板2的加热，能够避免熔盐泵5进液端出的熔盐液出现固态熔盐，从而保证熔盐泵5的安全稳定运行；
在罐体1中的熔盐液参与换热时，熔盐泵5开启，此时介质板2通过排挤罐体1底部处的熔盐液，使罐体1内的熔盐液能够被熔盐泵5最大限度的排空，从而大幅提高罐体1内熔盐液的利用率，进一步提高了熔盐储罐的热能利用效率。
需要说明的是，在罐体1内的熔盐液较多时，无论是熔盐泵5处于开启状态还是关闭状态，介质板2均位于罐体1的底部，在罐体1内的熔盐液较少且熔盐泵5关闭时，介质板2可以位于罐体1的底部，也可以位于熔盐液的上方进行储热。
在介质板2移动过程中，第二缝隙16用于熔盐液或空气的流动，避免介质板2对空气或熔盐液造成挤压以及介质板2与熔盐泵5出液端之间磨损的问题，第二缝隙16的具体尺寸可以根据实际需要进行设置，对此不作限制。
如图1、图2和图3所示，在一些实施例中，熔盐泵5包括泵体6、泵轴7和滤网8，泵体6设置在罐体1上，泵轴7的出液端与泵体6的进液端相连，泵轴7的进液端浸入熔盐 液并靠近罐体1的底部，介质板2套设在泵轴7上，介质板2的内壁与泵轴7的外壁之间设置有第二缝隙16，滤网8设置在泵轴7的进液端上。
可以理解的是，泵体6开启时，泵体6通过泵轴7将罐体1内的熔盐液增压向外输送，以实现熔盐液循环，且通过滤网8的设置，能够有效去除熔盐液中的固态熔盐、杂质等，保证泵体6的安全稳定运行。
其中，由于滤网8的设置，使得泵轴7的进液端无法贴合到罐体1的底部，导致泵轴7的进液端与罐体1的底部之间存在间距，该间距导致罐体1内的熔盐液无法被泵体6完全排空，因此通过介质板2的排挤作用，使罐体1底部处的熔盐液向上流动，进而保证罐体1内熔盐液能够最大限度的排空，从而大幅提高罐体1内熔盐液的利用率，进一步提高了熔盐储罐的热能利用效率。
需要说明的是，泵体6在罐体1上的具体设置方式可以根据实际需要进行设置，示例的，泵体6可以通过螺栓固定、焊接固定等方式固定设置在罐体1的顶部。
泵轴7在罐体1上的具体设置方式可以根据实际需要进行设置，示例的，泵轴7可以贯穿罐体1的顶部并延伸到罐体1的底部，且泵轴7贯穿罐体1处可以通过密封圈、焊接等方式密封，泵轴7的中心轴可以位于罐体1的竖直方向上，且泵轴7的中心轴与罐体1的中心轴不重合，以便于驱动装置4与介质板2之间的传动相连。
滤网8的具体类型可以根据实际需要进行设置，对此不作限制。
如图1和图2所示，在一些实施例中，介质板2的密度大于熔盐液的密度，驱动装置4包括卷扬机9，卷扬机9设置在罐体1上，卷扬机9的牵引绳10与介质板2相连；
其中，卷扬机9正转并驱动介质板2脱离熔盐液；
或卷扬机9反转并释放介质板2，以使介质板2浸入熔盐液。
可以理解的是，在介质板2需要脱离熔盐液时，卷扬机9正转，以卷绕牵引绳10，从而带动介质板2移动，以脱离熔盐液。
在介质板2需要浸入熔盐液时，卷扬机9反转，以释放牵引绳10，从而使介质板2基于自身重量移动，以浸入熔盐液。
需要说明的是，卷扬机9的具体类型可以根据实际需要进行设置，示例的，卷扬机9可以包括底座、卷筒、电机、减速机和牵引绳10，底座通过螺栓固定、焊接固定等方式固定设置在罐体1的顶部，卷筒转动设置在底座上，电机和减速机通过螺栓固定、焊接固定等方式固定设置在底座上，电机的输出轴与减速机的输入轴相连，减速机的输出轴与卷筒的转轴相连，牵引绳10的一端绕设在卷筒上，牵引绳10的另一端与介质板2相连。由此，在电机正转时，卷筒卷绕牵引绳10，在电机反转时，卷筒释放牵引绳10。
其中，牵引绳10的具体类型可以根据实际需要进行设置，示例的，牵引绳10可以是钢丝绳。
底座、卷筒、电机和减速机的具体类型可以根据实际需要进行设置，对此不作限制。
为保证介质板2在罐体1内稳定的移动，示例的，罐体1内设置有多个滑杆，介质板2上设置有多个滑套，滑套滑动套设在滑杆上。
如图1和图2所示，在一些实施例中，熔盐储罐还包括挂环11，挂环11设置在介质板2上靠近介质板2的重心处，挂环11与卷扬机9的牵引绳10相连。
可以理解的是，通过在靠近介质板2的重心处设置挂环11，并将牵引绳10与挂环11相连，不仅便于实现牵引绳10与介质板2的相连，而且使介质板2移动时更为稳定。
需要说明的是，在泵轴7的中心轴与介质板2的中心轴不重合时，由于介质板2需要套设在泵轴7上，因此介质板2的重心并非在介质板2的中心轴上，而是处于介质板2远离泵轴7的一端与介质板2的中心轴之间。
挂环11与牵引绳10之间的相连结构可以根据实际需要进行设置，示例的，牵引绳10焊接在挂环11上；牵引绳10系在挂环11上；牵引绳10通过挂钩与挂环11相连。
在一些实施例中，驱动装置4还包括电源接入组件，电源接入组件的电能输出端与卷扬机9的电能输入端和加热组件3的电能输入端相连。
可以理解的是，通过电源接入组件的设置，便于实现火电机组对卷扬机9和加热组件3同时供电，以保证介质板2的稳定运行。
需要说明的是，在用电需求较小时，火电机组将多余的电能通过电源接入组件输送到卷扬机9和加热组件3中，以在提高火电机组深度调峰能力的同时保证卷扬机9和加热组件3的稳定运行。
电源接入组件的具体类型可以根据实际需要进行设置，示例的，电源接入组件可以是变压器。
如图1和图2所示，在一些实施例中，电源接入组件的电能输出端与加热组件3的电能输入端通过耐高温线缆相连，熔盐储罐还包括导套12，导套12设置在罐体1上，导套12贯穿罐体1的罐壁，牵引绳10和耐高温线缆贯穿导套12。
可以理解的是，通过耐高温线缆的设置，在实现电源接入组件与加热组件3电性相连的同时能够适应介质板2的移动以及罐体1内的高温环境，有效延长了熔盐储罐整体的使用寿命；通过导套12的设置，使牵引绳10和耐高温线缆相对罐体1的位置能够保持恒定，从而保证介质板2的稳定移动，同时能够减小牵引绳10和耐高温线缆的磨损，有效延长熔盐储罐整体的使用寿命。
需要说明的是，导向套是两端贯通的管状结构，导向套在罐体1上的具体设置方式可以根据实际需要进行设置，示例的，导向套焊接在罐体1的顶部。
耐高温线缆的具体类型可以根据实际需要进行设置，对此不作限制。
如图4所示，在一些实施例中，介质板2包括多个板体13，多个板体13之间可拆卸的相连，加热组件3包括多个电阻丝14，多个电阻丝14分别设置在多个板体13内。
可以理解的是，通过多个板体13的可拆卸相连结构，便于介质板2的拆装维护，使整体的使用更为便捷；通过多个电阻丝14的设置，使多个板体13均能够储存热能和释放热能，从而保证介质板2对熔盐液的均匀加热。
需要说明的是，多个板体13之间的可拆卸相连结构可以根据实际需要进行设置，示例的，多个板体13之间可以通过卡扣相连、螺栓相连等可拆卸结构相连。
各个板体13的结构可以根据实际需要进行设置，对此不作限制。
电阻丝14在板体13内的设置方式可以根据实际需要进行设置，示例的，电阻丝14在板体13内呈蛇型分布。
多个电阻丝14之间可以串联，且多个电阻丝14之间具有相同的发热量。
