Background technology
Electrical engineering and it's automation major is a new branch of science in electric information field, at present, is being carried out electrically certainly
Dynamicization impart knowledge to students when, unspecial instructional device, if only instructing book knowledge, student can not it is well understood that and
The ability of practice is poor, generally requires teacher and leads student to go plant site to observe, very inconvenient, is brought to teacher's teaching tired
It is difficult.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is：There is provided one kind contributes to
Students ' Learning electric automatization, is the electric automatization teaching demonstration device that teachers ' teaching is brought convenience.
Electric automatization teaching demonstration device described in the utility model, including base, the inside of base are provided with battery,
The top of base is provided with plc controllers and tank, is electrically connected between plc controllers and battery, and the top of tank, which is provided with, draws water
Pump and test trough, the water inlet of suction pump go deep into the bottom of tank by suction hose, and the delivery port of suction pump is connected by drainpipe
Connect the water inlet of test trough, the inside of test trough is provided with liquid level sensor, the delivery port of test trough by return pipe connection water channel,
Return pipe is provided with motor-operated control valve, and motor-operated control valve, liquid level sensor and suction pump are all connected with plc controllers.
The side wall of described base be provided with charge port, charge port connection battery, battery can be charged there is provided
Continue electric energy.
A protective cover is hinged on the outside of described charge port, is shielded.
Operation principle and process：
In use, turning on the power, the liquid level to be kept in test trough is incorporated into by plc controllers, clicks on and starts,
Draw water pump work, and water sucks suction pump by suction hose, and is discharged into by drainpipe in test trough, when liquid level sensor is detected
When liquid level reaches the upper limit water level of test trough, suction pump is stopped, now, and plc controllers control motor-operated control valve is opened, water
Experimental tank of testing oneself flows back to tank by return pipe, electronic when liquid level sensor, which detects liquid level, reaches the lower limit water level of test trough
Control valve is closed, and now suction pump restarting is drawn water, so that, the water level in test trough can be made to remain under water level
Between limit and the water level upper limit, and realize Automated condtrol.
The utility model is had an advantageous effect in that compared with prior art：
Electric automatization teaching demonstration device described in the utility model, it is simple in construction, it is easy to operate, it is easy to student to know
Knowledge is combined with practice, effectively increases the Grasping level of student, is that giving lessons for electric automatization teacher brings conveniently.
