Description
Technical field
The utility model relates to a kind of Mechatronic device, in particular for making the coefficient of viscosity analyzer of Physical Experiment.
Background technology
In the Physical Experiment of middle school or university, the experiment of the coefficient of viscosity of measuring liquid is arranged.Usually adopt falling ball method in the experiment.Method is the fluid to be measured of packing in graduated cylinder, put into the steel ball of specified diameter to liquid surface, when treating that steel ball at the uniform velocity falls, measure certain segment distance institute's time spent that steel ball descends with stopwatch and ruler, then calculate the speed that steel ball descends, calculate the coefficient of viscosity of fluid to be measured by formula.This method need to be observed the position that steel ball descends by people's eyes, then manually presses manual time-keeping, and human factor is more, and measuring error is larger.
Summary of the invention
For addressing the above problem.The utility model provides a kind of coefficient of viscosity analyzer, and this coefficient of viscosity analyzer detects the position that steel ball descends automatically by sensor, automatically calculates the speed that steel ball descends by main control circuit, shows by display.Do not have human factor, measured result is more accurate,
The technical scheme that the utility model technical solution problem adopts is: invent a kind of coefficient of viscosity analyzer, be characterized in: the coefficient of viscosity analyzer has a graduated cylinder, at the graduated cylinder mouth guides is installed, at graduated cylinder a upper bracket and a lower carriage are installed, a light source and an optical sensor respectively are installed on each support, light source is connected wire and connects a main control board with optical sensor, main control board is installed in the housing, housing is provided with panel, display screen is installed on the panel, display screen connects main control board by wire, fitting operation button on the panel.
The beneficial effects of the utility model are that in the experiment of the coefficient of viscosity that adopts falling ball method measurement liquid, the utility model adopts electrooptical device to measure the position, whereabouts of steel ball, can eliminate human factor, measurement result degree of accuracy height.Calculate the steel ball decline rate by the single-chip microcomputer on the main control board, opened the direct display speed value of display screen, remove the process of calculating the steel ball decline rate from, convenient to operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural drawing of present embodiment.1 guides among the figure, 2 graduated cylinders, 3 upper brackets, pointer on 4, light source folder on 5, light source on 6, light source power line on 7,8 lower carriages, 9 times pointers, 10 times light source folders, 11 times light sources, 12 power leads, 13 housings, 14 main control boards, 15 power buttons, 16 reset keys, 17 arrange button, 18 display screens, 19 lower sensor wires, 20 lower sensors, 21 times lock-screws, 22 upper sensor wires, 23 upper sensors, lock-screw on 24.
Embodiment
As shown in drawings, mouth at graduated cylinder 2 is installed guides 1, install support 3 and lower carriage 8 at graduated cylinder 2, install pointer 4 and upper sensor 23 at upper bracket 3, upper light source 6 is installed on the upper bracket 3 by upper light source folder 5, pointer 9 and lower sensor 20 under lower carriage 8 is installed, lower light source 11 is installed on the lower carriage 8 by lower light source folder 10, the housing 13 interior installation governor circuit utmost points 14, lower light source 11 links to each other with main control board 14 by power lead 12, upper light source 6 links to each other with lower light source 11 by upper light source power line 7, upper sensor 23 links to each other with main control board 14 by upper sensor wire 22, and lower sensor 20 links to each other with main control board 14 by lower sensor wire 19, at the panel of housing display screen 18 is installed, display screen 18 links to each other with main control board 14 by wire, panel at housing is installed power button 15, reset key 16 and button 17 is set is installed lock-screw 24 at upper bracket 3, lock-screw 21 under lower carriage 8 is installed.
During experiment, at graduated cylinder 2 interior injection fluids to be measured, mobile upper bracket 3 and lower carriage 8, make pointer 4 and lower pointer 9 fingers on the scale that graduated cylinder 2 is set, respectively upper bracket 3 and lower carriage 8 are locked on the graduated cylinder 2 by upper lock-screw 24 and lower lock-screw 21, pressing power button 15 makes main control board 14 enter duty, operation setting button 17 input measurement distances, get the steel ball of a specified diameter and put into guides 1, steel ball falls into fluid to be measured by guides 1, block the light of upper light source 6 directive upper sensors 23 in the time of between steel ball is by upper light source 6 and upper sensor 23, upper sensor 23 changes into electric impulse signal with light signal and sends into main control board 14, main control board 14 beginning timing, block the light of lower light source 11 directive lower sensors 20 in the time of between steel ball is by lower light source 11 and lower sensor 20, lower sensor 20 changes into electric impulse signal with light signal and sends into main control board 14, main control board 14 timing finish, and the single-chip microcomputer on the main control board 14 calculates steel ball decline and speed shows at display screen 18.When needs are measured again, press reset key 16 and just can enter the state that remeasures of waiting for.When measuring end, again click power button 15 powered-downs.
