Abstract

The invention discloses an energy conversion demonstration device for teaching. The demonstration device comprises a transparent container, a blade assembly, a power generation assembly and a light gathering assembly, wherein the transparent container is used for holding liquid and comprises a first outlet; the blade assembly comprises rotatable blades, and the rotatable blades are arranged at a place corresponding to the first outlet; the power generation assembly is connected with the blade assembly; and the light gathering assembly is used for gathering outside solar rays into a first beam and enabling the first beam to be radiated to the liquid in the transparent container. When the liquid is heated to a boiling state and turns into hot steam under irradiation of the first beam, the hot steam escapes from the first outlet, so that the ambient air around the first outlet is heated and expanded and moves upwards to drive the rotatable blades to rotate, and the rotatable blades rotate to drive the power generation assembly to generate power. Through the mode above, the provided demonstration device can visually reflect energy conversion.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an energy conversion demonstration device for teaching. Background technique [0002] Energy conversion was proposed by Mayer in 1853, and the applied science is physics. Various energies (such as mechanical energy, internal energy, light energy, electrical energy, etc.) can be transformed into each other under certain conditions. [0003] The inventors of the present invention have found in the long-term research process that when current physics textbooks describe the relevant knowledge of energy conversion, they only list "energy conversion" experiments in the textbooks, such as hydropower stations, etc., which are too abstract and difficult for students to understand. . Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an energy conversion demonstration device for teaching, which can intuitively reflect the...
