Description
Technical field
The utility model relates to educational facilities, particularly scientific and technological demonstration teaching aid.
Background technology
In education sector, particularly primary school education, a great problem existing aspect in education of science and technology, is exactly how complicated Sci-tech Knowledge to be represented to the student to the low age in lively lovely mode.
Generating is to utilize the mode of cutting magnetic field line mechanical energy to be converted into the process of electric energy.Utilize hand mode, allow student's direct feeling to self-energy be converted into electric energy and by certain formal intuition show, this is the very direct forms of education of one.
In the hand power teaching aid of prior art, conventionally by several simple consumers, such as voltage table, bulb etc., show the electric energy that hand-operated mechanical the subject of knowledge and the object of knowledge changes into, the form of expression is uninteresting, interesting low, attractive force to student in education is little, and teaching efficiency is not good.
Utility model content
In order to solve the problems of the technologies described above, in the utility model, disclose a kind of hand power teaching aid, the technical solution of the utility model is to implement like this:
A kind of hand power teaching aid, comprising: casing; Panel, is provided with LED horse race lamp on described panel; For hand handle, described handle is arranged on described casing; Generating set, described generating set is positioned at described casing, is connected to described handle; Be connected to described generating set and described LED horse race lamp and according to the controller of LED horse race lamp described in described generating set output voltage control; And accessory power supply, described accessory power supply is positioned at described casing, is connected to described LED horse race lamp and described controller.
Further, be also provided with loudspeaker on described panel, wherein, described loudspeaker is connected to described controller and is subject to the control of described controller, and to be connected to described accessory power supply be that described loudspeaker is powered by described accessory power supply.
Further, be also provided with needle dc voltmeter on described panel, described needle dc voltmeter is measured the output voltage of described generating set.
Further, on described panel, be also provided with the bulb that is connected to described generating set.
Implement the technical matters that the technical solution of the utility model can solve form of expression dullness in prior art; Implement the technical solution of the utility model, by the multiple electric energy form of expression is set, can realizes and improve interesting, the technique effect of enhancing student to Knowledge Assimilation degree.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only a kind of embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of a kind of embodiment of the present utility model.
In above-mentioned accompanying drawing, each figure labelled notation represents respectively:
1-casing; 2-panel; 3-LED horse race lamp; 4-handle; 5-loudspeaker; 6-needle dc voltmeter; 7-bulb.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model-part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment of the present utility model is the intention of the senior class student Cui Xintong classmate of New Area, Wuxi City experimental primary school in school's characteristic science and technology course, after teacher Zou Jun instructs, forms.In a kind of embodiment of the present utility model, a kind of hand power teaching aid, as shown in Figure 1, comprising: casing 1; Panel 2, is provided with LED horse race lamp 3 on described panel 2; For hand handle 4, described handle 4 is arranged on described casing 1; Generating set (not shown), described generating set is positioned at described casing 1, is connected to described handle 4; Be connected to described generating set and described LED horse race lamp 3 and according to the controller (not shown) of LED horse race lamp 3 described in described generating set output voltage control; And accessory power supply (not shown), described accessory power supply is positioned at described casing 1, is connected to described LED horse race lamp 3 and described controller.
In this embodiment, in the time that student shakes described handle 4, described handle 4 drives the described generating set that is positioned at described casing, and the mechanical energy that student is exported described handle 4 by described generating set is converted into electric energy.Described controller is connected to described generating set, and according to brightness and the rolling speed of LED horse race lamp 3 described in the output voltage control of described generating set.When student's described handle 4 that stops the rotation, described generating set stops exporting electric energy, and described controller preferably shows specific light or sound effect according to hand power teaching aid described in the stop position control of described horse race lamp 3.Different from hand power teaching aid of the prior art, in this embodiment, in order to realize better lighting effects, the energy that only relies on hand power is not enough, and this embodiment also comprises accessory power supply.Described accessory power supply is powered to described controller, and is connected to described LED horse race lamp 3, stops exporting after electric energy especially in described generating set, and above-mentioned controller and described LED horse race lamp 3 are powered.
In this embodiment, preferably, on described panel 2, be also provided with loudspeaker 5, wherein, described loudspeaker 5 is connected to described controller and is subject to the control of described controller, and to be connected to described accessory power supply be that described loudspeaker is powered by described accessory power supply.Thus, described hand power teaching aid can, according to the rotation of described handle 4, by the multiple combination form of sound and light, show abundanter effect, for student, has better attractive force.
In this embodiment, preferably, on described panel 2, be also provided with needle dc voltmeter 6, described needle dc voltmeter 6 is measured the output voltage of described generating set.Described needle dc voltmeter 6 is a kind of additional electric energy forms of expression.
In this embodiment, preferably, on described panel 2, be also provided with the bulb 7 that is connected to described generating set.Described bulb 7 is forms of expression of a kind of additional electric energy.
It is to be noted; the foregoing is only preferred embodiment of the present utility model and oneself, not in order to limit the utility model, all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
