Abstract
It the utility model is related to Popular Science Education technical field, a kind of more particularly to safe voltage apparatus for demonstrating, including exhibition booth and the hand generator being located on the exhibition booth, what is be sequentially connected in series by wire and the hand generator is resistance, the one or three line card, voltmeter, the two or three line card and ammeter, and it is metal setting stick to be connected in parallel on the one or three line card and the two or three line card.A kind of safe voltage apparatus for demonstrating of the utility model kind, hand generator is shaken manually by spectators, the increase and decrease of hand speed can intuitively see the change of voltage very much in voltmeter and ammeter, and remove touching metal setting stick by using hand and experience the impression of electric shock, the fearful of people electric-tiger is warned by the utility model device, to the knowledge of people's science popularization safety utilization of electric power.
Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of safe voltage apparatus for demonstrating.
Background technology
Safe voltage, refer to that voltage that is directly lethal or disabling will not be made one, allow continuous contact under the conditions of general environment
" SELV " be 24V.Often occurs the accident of getting an electric shock and dying in people's daily life, this is all due to people to safety
The understanding of voltage is inadequate, caused by electricity consumption is improper.Therefore the knowledge to spectators' science popularization safe voltage is very necessary, and is passed through
The mode for allowing viewer experience to shock by electricity is then most direct effective manner.In the prior art, temporarily also corresponding device is not had to be used for
Demonstrate safe voltage.
The content of the invention
It is an object of the invention to provide it is a kind of allow spectators participate in it is interactive in can experience the impression of electric shock, it is and unlikely
In the safe voltage apparatus for demonstrating for causing personal safety.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of safe voltage apparatus for demonstrating, including exhibition booth and the hand generator that is located on the exhibition booth, by wire with
What the hand generator was sequentially connected in series is resistance, the one or three line card, voltmeter, the two or three line card and ammeter, is connected in parallel
In on the one or three line card and the two or three line card being metal setting stick.
Preferably, described hand generator is fixed on the exhibition booth by support, it include engine block,
Alternator shaft, handwheel disk and rocking handle.
Preferably, described metal setting stick is divided into left hand metal setting stick and right hand metal setting stick.
Preferably, described left hand metal setting stick is made up of left hand disk and left hand pallet, described right hand metal hand
Disk is made up of right hand disk and right hand pallet.
Compared with prior art, beneficial effects of the present invention are：
A kind of safe voltage apparatus for demonstrating of the present invention, start to shake hand generator, the increase and decrease of hand speed by spectators
The change of voltage can be intuitively seen very much in voltmeter and ammeter, and removes touching metal setting stick by using hand and experiences
The impression of electric shock, the fearful of people electric-tiger is warned by apparatus of the present invention, to the knowledge of people's science popularization safety utilization of electric power.
Brief description of the drawings
Fig. 1 is main structure diagram of the present invention；
Fig. 2 is side structure schematic view of the present invention；
Fig. 3 is overlooking the structure diagram of the present invention.
Embodiment
Referring to shown in accompanying drawing 1-3, a kind of safe voltage apparatus for demonstrating, including exhibition booth 1 and be located at hand on the exhibition booth 1
Generator 2, what is be sequentially connected in series by wire 3 and the hand generator 2 is resistance, the one or three line card 4, voltmeter the 5, the 2nd 3
Line card 6 and ammeter 7, it is metal setting stick 8 to be connected in parallel on the one or three line card 4 and the two or three line card 6.
Preferably, described hand generator 2 is fixed on the exhibition booth 1 by support 9, and it includes generator sheet
Body 2-1, alternator shaft 2-2, handwheel disk 2-3 and rocking handle 2-4.
Preferably, described metal setting stick 8 divides for left hand metal setting stick 10 and right hand metal setting stick 11.
Preferably, described left hand metal setting stick 10 is made up of left hand disk 10-1 and left hand pallet 10-2, described
Right hand metal setting stick 11 is made up of right hand disk 11-1 and right hand pallet 11-2.
Mode of operation and principle are：When spectators participate in, hand generator 2 is operated, rocking handle 2-4 is specially shaken with hands, shakes
Handle 2-4 rotation drives the handwheel disk 2-3 being attached thereto to rotate, and described handwheel disk 2-3 is connected to institute by machine shaft 2-2
The engine block 2-1 stated, now engine block 2-1 electric discharges pass through resistance, the one or three line card 4, the voltmeter being sequentially connected in series
5th, the two or three line card 6 and ammeter 7, to ensure safety, the resistance of resistance needs voltage and electricity sufficiently large and that can ensure that circuit
In safe range, spectators intuitively can be put stream when operating hand generator 2 by the pointer of voltmeter 5 and ammeter 7
Dynamic amplitude observes the change of electric current, and spectators experience electric shock if desired, it is only necessary to which will be manually placed into metal setting stick 8 to experience
To electric shock, being shocked by electricity if spectators want to experience by finger, apparatus of the present invention are also respectively equipped with finger plate 12 on metal setting stick 8,
Some finger can be touched finger plate 12 and experience electric shock by spectators, and the size for the intensity that shocks by electricity is by operating hand generator 2
Speed control, apparatus of the present invention mainly by electric-shock feeling by the fearful of people electric-tiger is warned, to people section Pu'an
The knowledge of full electricity consumption.
It is described above, it is only the preferred embodiments of the present invention, not limits the present invention,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But it is every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
