The principle of sand dune power generation is the same as that of hydroelectric power generation, and the power generation is carried out by utilizing the potential energy of water or sand at a high position. The difference is that hydroelectric water is automatically fed into a hydraulic turbine to do work, and sand is fed into the generator set by a conveyor 8 (which may be an existing conveyor belt).

The ancient waterwheel uses a large wheel disc, a water bucket is arranged around the wheel disc, high water flows into the water bucket on the upper part of the wheel disc, the wheel disc is pushed to rotate due to the potential energy of the water, and the middle shaft of the wheel disc drives tools such as a stone mill to work.

The specific gravity of the sand is 2.5 times that of water, when the water and the sand are at the same height and the same volume, the potential energy power generated by the sand is 2.5 times that of the water, and the sand potential energy power generation has great superiority.

The power generation process flow of the sand dune gravitational potential energy power generation equipment is described as follows:

sand at the height of the dune → the loader 15 digs the sand → the conveyor 8 conveys the sand → the sand hopper 3 of the generator set receives the sand → the large wheel disc 2 is stressed to generate a rotating moment to rotate → the sand reaches the lower end of the large wheel disc 2 and is poured → the sand outlet mechanism 9 receives the sand → the sand is sent to other spaces at the lower end of the dune.

The power generation process of the sand dune gravitational potential energy power generation equipment is described as follows:

gravitational potential energy of sand → rotational energy of the large wheel disc 2 → rotational energy of the transmission 5 → rotational power generation of the generator 6
