Abstract
The utility model discloses a kind of histogram statistics instructional device, belong to statistics teaching device.This device comprises base and is located at the fluid reservoir above base; Described base horizontally there is multiple column transparent vessel, solenoid, vertical tube and lower solenoid valve is provided with above each column transparent vessel, a pushbutton switch is provided with in the below of each column transparent vessel, wherein, riser upper end is communicated with fluid reservoir by solenoid, vertical tube lower end is communicated with column transparent vessel by lower solenoid valve, and solenoid is connected with power supply by the normally closed contact of pushbutton switch, and lower solenoid valve is connected with power supply by the normally opened contact of pushbutton switch.The utility model can facilitate teacher to demonstrate the process that histogram is added up, and improves the effect of classroom instruction.
Description
Technical field
The utility model relates to a kind of histogram statistics instructional device, belongs to statistics teaching device.
Background technology
In statistics course, teacher needs how data to be added up by histogram to student's demonstration, owing to lacking special educational aid, scale line and open column shape body can only be drawn on blackboard by teacher, when often adding up data, teacher all will in corresponding open column shape body full-filling certain altitude, this method not only wastes time and energy, and demonstrating effect is also not ideal enough.
Utility model content
The utility model, for the problem in background technology, proposes a kind of histogram statistics instructional device.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of histogram statistics instructional device, comprises base and is located at the fluid reservoir above base; Described base horizontally there is multiple column transparent vessel, solenoid, vertical tube and lower solenoid valve is provided with above each column transparent vessel, a pushbutton switch is provided with in the below of each column transparent vessel, wherein, riser upper end is communicated with fluid reservoir by solenoid, vertical tube lower end is communicated with column transparent vessel by lower solenoid valve, and solenoid is connected with power supply by the normally closed contact of pushbutton switch, and lower solenoid valve is connected with power supply by the normally opened contact of pushbutton switch.
As scheme optimization, the utility model also comprises a scale vertically arranged, and the lower end of described scale is connected with base.
Further, the top of described fluid reservoir is provided with inlet.
Technique effect:
1, the utility model can facilitate teacher to demonstrate the process that histogram is added up, and improves the effect of classroom instruction.
2, to the falling amount precise control of colored liquid, be beneficial to student and watch.
3, the utility model is easy to operate, designs ingenious, has good promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the constitutional diagram of the colored liquid in column transparent vessel when increasing a unit height.
Fig. 3 is the constitutional diagram of all data statisticss when completing.
Label title in Fig. 1 ~ Fig. 3: 1, base; 2, column transparent vessel; 3, fluid reservoir; 4, solenoid; 5, lower solenoid valve; 6, vertical tube; 7, pushbutton switch; 8, scale; 9, inlet; 10, colored liquid.
Embodiment
Below in conjunction with accompanying drawing, introduction is in further detail done to the technical solution of the utility model:
Structure of the present utility model as shown in Figure 1, comprises base 1 and is located at the fluid reservoir 3 above base 1; Described base 1 horizontally there is multiple column transparent vessel 2, solenoid 4, vertical tube 6 and lower solenoid valve 5 is provided with above each column transparent vessel 2, a pushbutton switch 7 is provided with in the below of each column transparent vessel 2, wherein, vertical tube 6 upper end is communicated with fluid reservoir 3 by solenoid 4, vertical tube 6 lower end is communicated with column transparent vessel 2 by lower solenoid valve 5, solenoid 4 is connected with power supply by the normally closed contact of pushbutton switch 7, and lower solenoid valve 5 is connected with power supply by the normally opened contact of pushbutton switch 7.
The utility model also comprises a scale 8 vertically arranged, and the lower end of described scale 8 is connected with base 1, and the scale on scale 8 can facilitate student to observe the liquid height in column transparent vessel 2.
The top of described fluid reservoir 3 is provided with inlet 9, can load colored liquid 10 by inlet 9 in fluid reservoir 3.
Described solenoid 4 and lower solenoid valve 5 all adopt the 2W040-10BH solenoid valve of Shanghai Hao Shi valve company limited.During solenoid valves, the valve open of solenoid valve, colored liquid can pass through from solenoid valve; During solenoid valve power-off, the valve closing of solenoid valve, colored liquid cannot pass through from solenoid valve.
Described pushbutton switch 7 adopts self-replaced type pushbutton switch.When pushbutton switch is not pressed, the normally opened contact of pushbutton switch disconnects, and normally closed contact closes, and corresponding solenoid 4 connects valve open with power supply, lower solenoid valve 5 disconnects valve closing with power supply, and the liquid in fluid reservoir 3 can flow in vertical tube 6 by solenoid 4; When the pushbutton switch is pressed, the normally opened contact of pushbutton switch closes, normally closed contact disconnects, corresponding solenoid 4 disconnects valve closing with power supply, lower solenoid valve 5 connects valve open with power supply, liquid in vertical tube 6 is flowed in the column transparent vessel 2 below it by lower solenoid valve 5, and the liquid in fluid reservoir 3 cannot be flowed in vertical tube 6 by solenoid 4.
Described vertical tube 6 is the flexible pipe vertically arranged, and the length internal diameter of all vertical tubes 6 is all identical, when any one pushbutton switch be pressed one time time, corresponding vertical tube 6 all can flow into the colored liquid of same volume to the column transparent vessel 2 below it.
During statistics, teacher only need press the button below any one column transparent vessel 2, colored liquid 10 in this column transparent vessel 2 just can increase a unit height (as shown in Figure 2), be a teacher when having added up all data, a column statistical graph represented by colored liquid is just shown and is given student (as shown in Figure 3).
