The invention relates to the technical field of gravity energy storage, in particular to a gravity energy storage device for a coal mine, which comprises a mine, a fixing frame mounted at the top of the mine, a fixed pulley mounted in the fixing frame, a lifting rope connected to the surface of the fixed pulley, a weight connected to one end, close to the mine, of the lifting rope, and a winding and unwinding wheel connected to the other end of the lifting rope. A generator motor is arranged at one end of the winding and unwinding wheel; the top end of the connecting block is inserted into the mounting sleeve in a sliding mode, when the limiting clamping block moves to the clamping groove, the limiting clamping block can be inserted into the clamping groove in a sliding mode under the action of the limiting spring, and then the connecting block is limited; and through the air cylinder connected to the top end of the mounting sleeve, the pulley frame is conveniently driven by the air cylinder to ascend and descend in the fixing frame, then the function of adjusting the mounting height of the fixed pulley according to the use requirement is achieved, and the practicability of the device is improved.
本发明涉及重力储能技术领域,具体为一种用于煤矿矿井的重力储能装置,包括:矿井,矿井的顶部安装有固定架,固定架的内部安装有定滑轮,定滑轮的表面连接有吊绳,吊绳靠近矿井的一端连接有重物,吊绳的另一端连接有收放卷轮,收放卷轮的一端设置有发电电动机;通过将连接块的顶端滑动插入安装套,当限位卡块移动至卡槽处时,限位卡块可以在限位弹簧的作用下滑动插入卡槽中,进而对连接块进行限位,通过安装套和连接块表面的安装孔和连接孔,便于通过安装螺栓将安装套和连接块固定连接起来,通过安装套顶端连接的气缸,便于通过气缸带动滑轮架在固定架内升降,进而实现根据使用需求调整定滑轮安装高度的功能,提高了装置的实用性。
