Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a gravity block which is convenient for automatic loading, unloading and stacking. Background Art

[0002] Gravity energy storage belongs to mechanical energy storage, and its energy storage medium is mainly solid matter and water. The basic principle of gravity energy storage is to lift and lower the energy storage medium based on the height difference, so as to complete the charging and discharging process of the energy storage system. The essence of the gravity energy storage system is to use the gravity of the earth to store and release kinetic energy. The use of solid medium for energy storage is more advantageous than that of liquid medium, and it does not rely on topography, climate and water sources; however, when solid medium is used as an energy storage medium, it is necessary to consider the floor space, stacking effect and safety of use. At present, most of the concrete is used as the gravity block medium, but it has certain defects: 1. When the concrete moves up and down for stacking, it will collide with each other and cause damage and the structural strength is not high and it is easy to break; 2. The metal shell on the outside is easy to corrode after long-term use, and the concrete inside the shell is easy to separate from the shell and shake and move inertia during the movement, which affects the safety of use; 3. It is not conducive to the automatic loading and unloading of the gravity block. When the gravity block is loaded and unloaded with the entire gravity energy storage system, the system has a great impact on the gravity block, and the concrete gravity block is very easy to be damaged.

As the conveyor belt moves, the open crocodile jaw clamp 1 meets the hanging shaft 3 of the gravity energy storage system. At this time, the upper track 5 loses its pressure on the guide wheel 1-1-2, the upper jaw plate 1-1 rotates counterclockwise, and the crocodile jaw clamp 1 is in an open state. The clamp 1 is in a clamped state against the hanging shaft 3, and the gravity block is successfully loaded onto the circular chain 4 of the gravity energy storage system at a high place, and is transported to a low place as the sprocket rotates.
