Patent Application
20140011174
The present invention relates to a teaching aid, and in particular, to a portable solar teaching aid, which allows the students to get a direct vision and hands-on operation of photovoltaic effect so as to help them to better understand such photovoltaic effect.
At present, on the initiative of our government, low carbon and environmental protection have been gradually accepted and understood by people in China. The whole society, especially schools, has started to learn and publicize the knowledge of low carbon and environmental protection, guiding people in developing and utilizing new energy, especially solar energy which is inexhaustible and will be never used up. However, due to the lack of a suitable teaching aid, most of schools are currently limited to theoretical teaching and the students are not able to have a direct vision and hands-on operation of the application of solar energy, therefore it becomes an urgent matter to develop a portable solar teaching aid.
It is therefore an object of the present invention to provide a portable solar teaching aid, which overcomes the above-described shortcomings of prior art, help the students to get a direct vision of photovoltaic effect and application of solar energy and allow them to have hands-on operation of this solar teaching aid. Depending on the demonstrations or experiments of solar teaching aid, the students are able to better understand the photovoltaic effect and application of solar energy.
To achieve the above-mentioned purpose, the invention adopts the following technical scheme:
A portable solar teaching aid is composed of:
A portable case, which the case body and cover are flexibly connected;
A sunlight analog device, of which the analog light source is fixed in the case body;
A solar energy conversion device for converting analog sunlight into electric energy;
Teaching appliances that work with the solar energy conversion device.
The case body and cover of the said portable case are flexibly connected and the sunlight analog device is fixed in the case body; the sunlight analog device includes:
A reflector, which extends from the bottom to the side wall of the portable case;
A light source, which is fixed inside the reflector; with electric supply, the light source generates analog sunlight. With the reflector, the analog sunlight is turned toward the opening of the case.
The said analog light source is a xenon lamp.
The said solar energy conversion device is a solar-cell panel, of which the front faces to the opening of the portable case so that the light coming out of the sunlight analog device can be converted into electric energy and then transmitted by wire.
The said solar-cell panel, there is a piece of super white tempering glass.
On the said cover of the portable case, there is a voltmeter and an ammeter respectively connected to the output circuit of solar-cell panel.
The said teaching appliances include a multicolored light-emitting diode lamp and a direct current fan.
There is an interface on the said case body for connecting to the sunlight analog device and an output port on the cover for connecting to the solar-cell panel. The said teaching appliances have electrical connection via output port.
On the side wall of the said case body, there is a cooling fan having electrical connection with electric supply.
The said portable case has an aluminum shell, and holders are equipped inside the case cover for fixing teaching appliances.
Due to the adoption of the above structure, the present invention provides a portable case to install a sunlight analog device, a solar energy conversion device and some teaching appliances in, thereby it is easy to carry and suitable for teaching purpose. The sunlight analog device is powered by electric supply to generate light which is similar to sunlight. The light can be converted into electric energy by solar energy conversion device and then transmitted to teaching appliances. This invention helps the students to get a direct vision of photovoltaic effect and have a hands-on operation of the application of solar energy so as to strengthen their awareness of low carbon and their understanding of the application of new energy.
Now we will introduce this invention and its application through illustrations and detailed description.
The case cover 12 has a voltmeter 6 and ammeter 5, which have electrical connection with solar-cell panel. The reading of voltmeter 6 or ammeter 5 shows the output of electricity from solar-cell panel, and the electricity is transmitted via output 7 inside the case cover 12.
The teaching appliances include a multicolored light-emitting diode lamp 8 and a direct current fan 9, which can respectively be put on holder 81 and holder 91 inside the case cover 12. Take them off during demonstration and connect the wire to electric energy output 7 so that the teaching appliances can start operation. Of course, other or more teaching appliances can be added at will during demonstration, which can operate in the same manner.
There is a cooling fan 24 on the side wall of the case body, which can be connected to the electric supply to reduce the working temperature of analog light source.
Although the application has been described in great detail in the foregoing specification, it is to be understood that such descriptions of the embodiments are provided not for the purpose of limiting the scope of the invention as defined by the appended claims.
