Abstract

The invention relates to teaching experiment tools, and discloses an electricity-generating experiment device for teaching. The device comprises a shell, a water inlet, a water outlet, an impeller, a fixed mount, a connecting rod, a permanent magnet, a copper wire and a bulb. The water inlet and the water outlet are systematically formed in the shell. The impeller is arranged between the water inlet and the water outlet in the shell. When liquid flows to the water outlet from the water inlet, the impeller can be driven to rotate. The fixed mount is a hollow cylinder. One end of the connecting rod is fixed to the rotation center of the impeller, and the other end of the connecting rod penetrates through the fixed mount. The permanent magnet is fixed to the portion, located in the fixed mount, of the connecting rod. The permanent magnet comprises an N pole and an S pole, and the N pole and the S pole are symmetrically arranged on the two sides of the connecting rod respectively. The copper wire is wound around the fixed mount to form a circuit. The bulb is connected to the circuit formed by the copper wire. By the adoption of the device, the theoretical knowledge on textbooks about converting mechanical energy into electric energy can be demonstrated through a dynamic test process.

Description

technical field [0001] The invention relates to a teaching experiment tool, in particular to a power generation experiment device for teaching. Background technique [0002] In physics teaching, knowledge about the conversion of mechanical energy into electrical energy is involved. Students usually acquire this knowledge in textbooks, but only stay in theory, and have not intuitively felt or tried the process of converting mechanical energy into electrical energy. Moreover, the laboratories of most schools also lack such experimental devices, resulting in the teaching in this area being too theoretical and lacking intuitive experimental demonstrations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power generation experimental device for teaching, which can be used for students' experiments in the school laboratory, so that students can actually observe the theoretical knowledge in textbooks about the convers...
