Description

Memory alloy spring demonstrator

technical field

The utility model belongs to the field of physical experiment instruments and relates to a memory alloy spring demonstration instrument.

Background technique

The characteristic of the memory alloy spring is that it can remember its own shape at a certain temperature. When the temperature changes, the shape changes, and when it returns to the original temperature, the memory alloy spring also returns to its original shape. The demonstration method of existing memory alloy spring demonstration experiment is: memory alloy spring is placed in plastic basin, water is heated in plastic basin, memory alloy spring shape changes, then the hot water in the basin is poured out, memory alloy spring It slowly returned to its original state. It is not only troublesome but also unsafe to heat water and pour hot water during the whole experiment.

Contents of the invention

In order to solve the existing problems, the purpose of this utility model is to provide a memory alloy spring demonstrator, which is safe and does not need to pour hot water.

The technical solution adopted by the utility model to solve the technical problems is: memory alloy spring demonstrator, including water heater, base, transparent glass pool, panel, the water heater is cylindrical, and the transparent glass pool is cuboid and made of high temperature resistant material. Both are fixed on the base, the top of the water heater is provided with a water heater cover that is movably connected with it, a panel is fixedly connected between the water heater and the transparent glass pool, and a first communicating pipe and a second communicating pipe are sealed and connected, and the panel There is a pumping switch and a heating switch on the top, an electric water pump is installed in the first connecting pipe, and a water valve is installed on the second connecting pipe. When the pumping switch is pressed, the electric water pump can automatically pump the water in the glass pool into the water heater and drain the glass. After the water in the pool is filled, the pumping switch will automatically pop up, the electric water pump will stop working and ensure that the water does not flow backwards, press the heating switch, the water heater will heat until the water boils and then keep warm. In the transparent glass pool, it is slightly higher than the top of the second connecting pipe A dividing plate is arranged, and a plurality of water permeable holes are arranged on the dividing plate.

When in use, put the memory alloy spring on the partition in the glass pool, close the water valve, open the water heater cover, pour an appropriate amount of water into the water heater and cover the water heater cover, press the heating switch, and wait for the water in the water heater to boil. Open the water valve, and the hot water in the water heater will flow into the transparent glass pool through the second connecting pipe. When the hot water submerges the memory alloy spring through multiple permeable holes, you can see the shape of the memory alloy spring changes sharply. Close the water valve , press the pumping switch, the electric water pump will automatically pump the water in the glass pool to the water heater, when the water in the glass pool is drained, as the temperature drops, the memory alloy spring slowly returns to its original state.

The beneficial effect of the utility model is that it is simple, convenient and practical, and the experimental effect is obvious and safe.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, the memory alloy spring demonstrator of the present utility model comprises a water heater 1, a base 2, a transparent glass pool 8, and a panel 13. Both of them are fixed on the base 2. The top of the water heater 1 is provided with a water heater cover 14 that is movably connected with it. A panel 13 is fixedly connected between the water heater 1 and the transparent glass pool 8, and a first communication connection is sealed. Pipe 5 and the second connecting pipe 6, the panel 13 is provided with a pumping switch 11 and a heating switch 12, the first connecting pipe 5 is equipped with an electric water pump 4, the second connecting pipe 6 is provided with a water valve 3, press the pumping switch 11. The electric water pump 4 can automatically pump the water in the glass pool 8 into the water heater 1. After the water in the glass pool 8 is drained, the pumping switch 11 will automatically pop up, and the electric water pump 4 will stop working and ensure that the water does not flow backwards. Heating switch 12, water heater 1 will be heated to the heat preservation after water boils always, in transparent glass pool 8, slightly higher than the second communicating pipe 6 top places are provided with dividing plate 9, and dividing plate 9 is provided with a plurality of permeable holes 7.

During use, put the memory alloy spring 10 on the partition plate 9 in the glass pool 8, close the water valve 3, open the water heater cover 14, inject an appropriate amount of water into the water heater 1 and cover the water heater cover 14, press the heating switch 12 After the water in the water heater 1 boils, open the water valve 3, and the hot water in the water heater 1 flows into the transparent glass pool 8 through the second connecting pipe 6. When the hot water passes through a plurality of permeable holes 7 and submerges the memory alloy spring 10 , it can be seen that the shape of the memory alloy spring 10 changes sharply, close the water valve 3, press the pumping switch 11, the electric water pump 4 will automatically pump the water in the glass pool 8 into the water heater 1, when the water in the glass pool 8 After water is drained, along with the reduction of temperature, memory alloy spring 10 returns to original state slowly again.
