Problems solved by technology
[0003] For the demonstration of thermoelectric power generation, most of the existing portable thermoelectric power generation demonstration instruments for teaching are relatively simple in structure and insufficient in protection ability, so that the device is often damaged due to bumps when it is carried and used, which affects the normal demonstration teaching of the device, and at the same time increases The maintenance cost of the device, for this reason, we propose a thermoelectric power generation demonstration instrument for teaching

The invention discloses a temperature difference power generation demonstration instrument for teaching. The temperature difference power generation demonstration instrument for teaching comprises a base, a plurality of supporting columns, a temperature difference power generation mechanism, an alcohol lamp, two fixing pieces and a clamping piece, wherein the supporting columns are symmetrically and fixedly mounted at the top of the base; the temperature difference power generation mechanism is positioned at the tops of the supporting columns; the temperature difference power generation mechanism is fixedly connected with the top ends, and the alcohol lamp is positioned at the bottom of the temperature difference power generation mechanism; and the two fixing pieces are symmetrically and movably installed at the bottom of the temperature difference power generation mechanism through hinges. The temperature difference power generation demonstration instrument for teaching can hide and fold a demonstration mechanism when the device is carried without demonstration through the temperature difference power generation mechanism, so that the demonstration mechanism is prevented from being damaged due to collision in the carrying process; and meanwhile, the alcohol lamp for providing temperature difference can be fixed through the fixing pieces and the clamping piece, so that an alcohol lamp does not need to be additionally carried, and the omission of the alcohol lamp is prevented from affecting normal demonstration teaching.
Description
technical field [0001] The invention relates to the technical field of teaching, in particular to a thermoelectric power generation demonstration instrument for teaching. Background technique [0002] Physics teaching is a very important subject in the teaching process of the school, and the teaching of electricity is the most important thing in the teaching of physics. During the teaching process of the physics class, the actual demonstration can enable students to directly observe the actual effect , with good teaching effect. [0003] For the demonstration of thermoelectric power generation, most of the existing portable thermoelectric power generation demonstration instruments for teaching are relatively simple in structure and insufficient in protection ability, so that the device is often damaged due to bumps when it is carried and used, which affects the normal demonstration teaching of the device, and at the same time increases The maintenance cost of the device, fo...
