Description

A kind of Self-cleaning blackboard

Technical field

The present invention relates to teaching aid, particularly relate to a kind of Self-cleaning blackboard.

Background technology

Blackboard not refers in particular to the plate face of black, traditional sense is said it be one can the plane of repeated writing, plate face is hard, is used for teaching.Make with plank or ground glass etc., can to write above with specific writing materials such as chalks.Mostly be black, blackish green, white.The multiplex a kind of article being referred to as sand table of ancient Chinese teaching, with hardwood repeated writing on sandy soil, but because sandy soil are softness, it can not be interpreted as is a kind of blackboard.

Middle Ages; it is found that lime and water are mixed and made into block; write at the article surface that dark color is hard by the method being similar to charcoal pencil; to 19th century; people are coated in board surface with pitch-dark; to protect plank not to be etched, the Main Function of blackboard is not teaching at that time certainly, until mid-term in 19th century, just all over the world, school came into vogue.

Over more than 200 year, blackboard from the earliest spread upon plank with blacking, the hard objects such as cement surface, to the water mill glass of the nineties, color coated steel sheet, composite panel .... the witness development step by step of world's educational undertaking, for the mankind convey knowledge, universal education, has made distinctions won on the battlefield.The kind of existing blackboard also starts to become complicated various, has blackboard, green plate from color point, blank .... there is surface plate, cambered plate from surface configuration point, have support portable plate from structure composition point, draw back plate, lifter plate, magnet board, blackboard for education is had, office blank, billboard from purposes point, Graphic Panel .. and blackboard for education has electronic blackboard, Multifunctional combined board, combination push-and-pull blackboard, interactive electric whiteboard, band curtain projection plate etc.

Traditional blackboard and chalk are with the use of the object realizing imparting knowledge to students, but when blackboard eraser removes, the physical and mental health of a large amount of dust to user causes great harm, especially numerous people teacher, is very easy to cause the generation of PUD D owing to contacting this type of dust for a long time.

Summary of the invention

For solving the problem, the invention provides a kind of can realization and autonomous wiping being carried out to blackboard, the technical scheme without the need to external force is supported:

A kind of Self-cleaning blackboard, main body is blackboard, also comprise slide rail A, slide rail B, walking track, stepper motor, from wiping equipment and power switch, slide rail A is fixedly installed on blackboard top edge, slide rail B is fixedly installed on blackboard lower limb, walking race orthogonal is arranged between slide rail A and slide rail B, walking track two ends are provided with stepper motor, stepper motor and slide rail A, slide rail B is connected, be provided with from wiping equipment inside walking track, slide up and down along walking track from wiping equipment, described stepper motor, be interconnected by wire from wiping equipment and power switch, power switch is arranged on optional position, blackboard side.

Further, from wiping device structure be: comprise shell, electric rotating machine, circular wiping board, servomotor, PLC control box and position sensor, enclosure is provided with electric rotating machine and PLC control box, electric rotating machine is arranged on outer casing bottom, the revolving spindle of electric rotating machine goes out case surface and circular wiping board is fixedly linked, cover top portion arranges servomotor, be connected by servomotor and walking track and move up and down along orbital direction of walking, servomotor upper and lower side is fixedly installed position sensor, described electric rotating machine, servomotor and position sensor are all connected with PLC control box by wire, PLC control box and described power switch conducts.

Further, also comprise wireless start button, wireless start button is connected in transmission of wireless signals mode with wireless signal generator, and it is inner that wireless signal generator is arranged on described power switch, by wire and power switch conducts.

Beneficial effect of the present invention is:

(1) the present invention is by slide rail A, slide rail B, walking track, stepper motor, autonomous carry out wiping to blackboard from wiping equipment and power switch with the use of achieving, without the need to external force support, its automaticity is high, significantly reduces the able-bodied infringement of user.

(2) in wiping equipment, electric rotating machine and servomotor is provided with in the present invention, ensure the wiping that this equipment drives circular wiping board to carry out blackboard by electric rotating machine, moved up and down on walking track by servomotor and realize wiping object, its structure is simple, convenient realization.

(3) also comprise wireless start button in invention, user can manipulate this equipment outside certain distance, greatly increases the serviceability of this equipment.
