The utility model discloses an adopt dustless green board to replace traditional blackboard, after water -soluble chalk was write on dustless green board, direct cleaning with cylinder clearing cloth water spray could to reach dustless purpose, and then avoided human respiratory track of dust pollution and equipment, and the consumption of water -soluble chalk is little, and the practicality is strong, has practiced thrift the resource, all can write on wet dustless green board futilely, the clear water clean can, need not to use dedicated clean water.
Description
Technical field
The utility model relates to multimedia teaching field, particularly, relates to a kind of numeral teaching system.
Background technology
Progressively improve along with to the requirement of quality of instruction and teaching environment, the pattern of the dependence blackboard writing formula that tradition is simple is no longer applicable to modern teaching mode, and increasing multimedia digital classroom replaces.
Multimedia digital classroom generally all comprises the teaching equipments such as electronic whiteboard, the projector coordinated with electronic whiteboard and middle control machine, teaching resource is stocked for the ease of more diversified, multimedia digital classroom is also provided with the blackboard coordinated with electronic whiteboard, teacher's timely updates when being convenient to teach, so that student better understands the content that electronic whiteboard shows.
The blackboard adopted in existing digital library general or with chalk with the use of, what can cause produces a large amount of dust in the process of writing, and not only can affect the respiratory tract of inspirator, but also can enter into the serviceable life that teaching equipment affects teaching equipment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of numeral teaching system, to overcome the problem of the dust pollution that existing digital library causes because of the use of blackboard.
The technical scheme in the invention for solving the above technical problem is: numeral teaching system, the projector comprise the electronic whiteboard be arranged on body of wall, coordinating with electronic whiteboard, the both sides of electronic whiteboard are provided with dustless green plate, the both sides of dustless green plate are provided with draw-in groove, cylinder wiper is provided with between 2 draw-in grooves, the sidewall of dustless green plate is provided with the stationary magazine creel for placing Water-soluble chalk, and ground is provided with dais, and the middle part at dais is provided with computing machine.The blackboard adopted in existing digital library general or with chalk with the use of, what can cause produces a large amount of dust in the process of writing, not only can affect the respiratory tract of inspirator, but also the serviceable life that teaching equipment affects teaching equipment can be entered into, dustless green plate described in the utility model is a kind of prior art, specifically refer to the clipboard for Water-soluble chalk, effect and traditional blackboard and chalk similar, but it does not produce dust, described Water-soluble chalk specifically refers to the lettering pen be made by water-soluble material and titanium dioxide, it is different from traditional chalk gypsum used, direct cylinder wiper water spray carries out wiping, the utility model replaces traditional blackboard by adopting dustless green plate, after Water-soluble chalk is write on dustless green plate, direct use directly carries out wiping with cylinder wiper water spray, thus reach dustless object, and then avoid dust pollution human respiratory tract and equipment, and the consumption of Water-soluble chalk is little, practical, save resource, dry wet dustless green plate is write, and clear water wiping, without the need to using special cleaning water, so, the utility model overcomes the problem of the dust pollution that existing digital library causes because of the use of blackboard.
Further, cylinder wiper comprises stationary shaft, and is set in the sponge on stationary shaft.Clear water is sprayed at sponge soaks sponge can to the conscientious wiping of dustless green plate, simply easy to operate.
Further, projector is arranged on top, classroom by suspension bracket.Described suspension bracket specifically refers to a kind of installing mechanism being fixed on top, classroom, and its movable end is connected with projector.
Further, computing machine is connected with audio amplifier.The effect amplified is played in the setting of audio amplifier, refer in particular to that space, classroom compares large when more can play its effect.
Further, audio amplifier is located on body of wall, and audio amplifier is symmetrically arranged with 2 above electronic whiteboard.
Further, body of wall is provided with air switch.Air switch plays a protective role, but during current capacity in circuit, automatic cut-off power, avoids causing danger.
Further, body of wall is provided with network cable box.By when installing for netting twine rolling to network cable box, avoid for netting twine in a jumble, affect attractive in appearance.
Further, dustless green plate is push-pull structure.Push-pull structure specifically refers on the body of wall that dustless green plate is installed by upper lower bayonet slot, can realize moving left and right.
To sum up, the beneficial effects of the utility model are:
The utility model replaces traditional blackboard by adopting dustless green plate, after Water-soluble chalk is write on dustless green plate, direct use directly carries out wiping with cylinder wiper water spray, thus reaches dustless object, and then avoids dust pollution human respiratory tract and equipment; And the consumption of Water-soluble chalk is little, practical, saved resource, dry wet dustless green plate is write, and clear water wiping, without the need to using special cleaning water.
