Abstract
The utility model relates to a fast demonstration instrument of a memory alloy spring. The instrument comprises a transparent glass tank, an electric furnace, axial flow fans, and a memory alloy spring. Base feet are arranged at positions approaching the edges of the front side, the rear side, the left side, and the right side of the lower side surface of the bottom of the transparent glass tank. The electric furnace is fixedly arranged at the center of the upper side surface of the tank bottom; circular holes are respectively arranged at positions, at the left side and the right side of the electric furnace, at the tank bottom; and the axial flow fans are respectively installed in the circular holes, wherein the wind blown by fans is from bottom to up. The memory alloy spring is lifted horizontally by two soft and fine metal wires that are fixed at the transparent glass tank; the distance between the lowest end of the memory alloy spring and the upper surface of the electric furnace is about 4 centimeters; and the memory alloy spring employs the material enabling the spring to be shortened with the temperature rising; and the transparent glass tank is made of high temperature-resistant transparent glass fiber reinforced plastics. After the power supply of the electric furnace is connected, the memory alloy spring shrinks and rises under the high temperature of the electric furnace; and after the power supply of the electric furnace is disconnected, the axial flow fans are started and the hot air of the transparent glass tank can be dissipated rapidly so as to make preparation for the next demonstration. The beneficial effects of the instrument are as follows: the instrument is simple, convenient, and practical; and the experiment effect is obvious and secure.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, relates to a kind of quick memory alloy spring demonstrator.
Background technology
The characteristic of memory alloy spring is to remember under certain temperature the shape of oneself, during temperature variation, and alteration of form, when getting back to original temperature, memory alloy spring also restores to the original state.The demenstration method of existing memory alloy spring lecture experiment is: memory alloy spring is placed in the plastics basin, in the plastics basin, inject hot water, the memory alloy spring shape changes, and then the hot water in the basin is poured out or is extracted out with water pump, and memory alloy spring slowly restores to the original state again.Will add hot-water flooding or take out hot water in whole experiment, not only trouble is also dangerous.
Summary of the invention
In order to solve the problem of existence, the purpose of this utility model provides a kind of quick memory alloy spring demonstrator, and water is not only safe but also not quick.
The technical scheme that its technical matters that solves the utility model adopts is: quick memory alloy spring demonstrator, comprise the clear glass bucket, electric furnace, axial flow blower and memory alloy spring, it is characterized in that: described clear glass bucket bucket sidewall is near the bung place, about respectively be provided with a fixed orifice, the side is provided with footing by edge all around under its bucket, bucket upper side center, the end is set with electric furnace, respectively have a circular hole at the bottom of the bucket of the described electric furnace left and right sides, wind direction axial flow blower from bottom to top all is installed in each circular hole, two soft tinsel levels that described memory alloy spring is fixed on the clear glass bucket are sling, the least significant end of memory alloy spring is apart from about 4 centimetres of the upper surfaces of electric furnace, memory alloy spring is selected for use with temperature rising contraction in length type, and described clear glass bucket is made by thermostable transparent fiberglass.
During use, connect the power supply of electric furnace, memory alloy spring shrinks under electric furnace high temperature and rises.When thinking fast cooling, can disconnect the power supply of electric furnace, start axial flow blower, the hot gas of clear glass bucket can be dispelled rapidly, for demonstration is next time prepared.
The beneficial effects of the utility model are, simple and convenient practicality, experiment effect obviously, safety.
