Abstract
The utility model provides a demonstration device for analogy of water pressure and electric voltage, which belongs to teaching aids and can demonstrate common points of water pressure and electric voltage. The demonstration device comprises a water pump and a universal meter, and is structurally characterized in that the water pump is connected with U-shaped pipes through a pipeline respectively,a water wheel is arranged inside a cup body on the bottom portion of a branch pipe of the pipeline, and the universal meter is connected with a slide rheostat, a switch and a bulb respectively.
Description
Technical field:
The utility model is the teaching aid that belongs to teaching.
Background technology:
Hydraulic pressure is the pressure that adds on the water, and same voltage can be understood as the pressure that is added in the electricity on certain section conductor, and both have the place that much communicates; But be difficult to explain their common ground during teaching, and do not have the demonstration teaching aid of the perceptual knowledge of this respect contrast.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of hydraulic pressure that can demonstrate common ground between hydraulic pressure, the voltage, the apparatus for demonstrating of voltage analogy are provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises water pump, multimeter, and its structural feature water pump links to each other with U type pipe respectively by pipeline, is provided with water wheels in the cup of the arm bottom of pipeline; Multimeter links to each other by the same respectively slide rheostat of lead, switch, bulb.
The beneficial effects of the utility model:
The utility model can solve in the classroom instruction, the comparison problem directly perceived of the common ground of hydraulic pressure and voltage; In addition, assembly of the present utility model is few, and simple, is easy to make, is easy to promote.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises water pump 10, multimeter 5, and water pump 10 links to each other with U type pipe 11,6 respectively by pipeline 12, is provided with water wheels 7 in the cup 9 of arm 8 bottoms of pipeline 12; Multimeter 5 links to each other with slide rheostat 3, switch 2, bulb 1 respectively by lead 4.
Utilize the pressure that water forms on the water pump 10, in U type pipe 11,6, put into half water and be used to show hydraulic pressure.
Utilize the variation of the variation observation voltage of slide rheostat 3.
