Metallofullerene derivatives, a preparing method thereof and an energy storage and conversion method of the derivatives are disclosed. The derivatives are obtained by modifying the surface of metallofullerene with derivatives of a nitroxide free radical micromolecule that is 2,2,6,6-tetramethylpiperidinooxy through an addition reaction. The metallofullerene derivatives are radiated by adopting ultraviolet light, and then participate catalytic oxidation reactions, the energy storage rate and energy conversion rate are high, storage of ultraviolet light energy and conversion from the light energy to chemical energy are achieved, and the energy storage and conversion method and process are simple. An electron transfer process of the metallofullerene derivatives radiated by the ultraviolet light can be analyzed by a conventional test instrument, the electron transfer situation can be reflected by changes of electron paramagnetic signals, and sensitivity is high. The time scale in the electron transfer process can be detected as an expansion.

The invention discloses a garbage cleaning device, which comprises a trolley, a roller brush, and a collection bag. The roller brush is rotatably arranged on the front side of the carriage, the collection bag is arranged on the rear side of the collection shovel, and the roller brush is rotatably arranged on the collection shovel. At the front end, the collecting shovel is rotationally connected to the compartment through the first rotating shaft. The collecting shovel is fixedly provided with a first connecting rod and a second connecting rod. Both the first connecting rod and the second connecting rod are fixedly connected to the first rotating shaft. The first connecting rod One end is fixedly connected with the collecting shovel, and the other end extends into the carriage. The end of the first connecting rod is provided with an arc-shaped guide rod, and a second rotating shaft is provided for rotating in the carriage. A swing rod is arranged on the second rotating shaft. The free end of the roller is provided with a roller, and the roller is slidably arranged in the guide rail of the arc-shaped guide rod. The wheel is fixedly connected with a third rotating shaft, and the third rotating shaft drives the second rotating shaft and the roller brush to rotate. The invention has the advantages of low cost and light weight, and has the advantages of energy saving and emission reduction.
