Abstract
The utility model relates to a simple and easy teaching experiment device, including upper groove, support, balloon, fixed loop, the next groove, backwash pump, the vertical setting of support column that the outer wall was equipped with the ladder platform is on the base, and the chamber is acceptd to the squeeze receptacle and upper groove is all connected on the support column through the horizontal pole, the next groove lower extreme is equipped with the delivery port and the mouth that flows back, and the delivery port below is equipped with the balloon, and a backward flow mouthful logical pipe is connected with the collecting tank, the backwash pump is intake in the end arranges the collecting tank in, goes out the water end (W. E. ) setting on upper groove, constantly result in balloon volume gain and finally bursting to water injection in the next groove through upper groove, prove through the political point view of audio -visual mode to " quantitative change production qualitative change ".
Description
Technical field
The utility model relates to a kind of political class instructional device, is specifically related to a kind of simple teaching experimental provision that can intuitively explain political point view.
Background technology
In the time of Political Teaching, teacher to quantitative change to qualitative change process instruction, mostly be and use books, chalk and blackboard to impart knowledge to students to student, and the content that politics lesson relates to is not only extensive, and abstract, only rely on very abstract of books, chalk and blackboard, be not easy to student and understand, it is more difficult that student accepts, and teaching efficiency is poor.
Utility model content
In order to solve uninteresting, the abstract problem of political point view explanation, the utility model has designed a kind of simple teaching experimental provision.
Concrete technology contents of the present utility model is: a kind of simple teaching experimental provision, comprise upper groove, support, balloon, retainer ring, the next groove, reflux pump, the support column that outer wall is provided with ladder platform is vertically arranged on base, squeeze receptacle host cavity and upper groove are all connected on support column by cross bar, cross bar one end is fixedly connected with retainer ring, the other end is connected to by bearing on the ladder platform of support column outer wall, and described squeeze receptacle host cavity and upper groove coordinate respectively and be assemblied in corresponding retainer ring; Upper groove and the next groove distribute up and down, and upper groove below is provided with the water filling port that points to the next groove inner chamber, and described water filling port is provided with magnetic valve; The next groove lower end is provided with delivery port and refluxing opening, and delivery port below is provided with balloon, and refluxing opening is connected with collecting tank by water pipe; Reflux pump water inlet end is placed in collecting tank, and water side is arranged on upper groove.
Cross bar is connected to corresponding bearing outer wall by the mode of welding; The internal diameter of two retainer rings matches with the external diameter of the next groove or upper groove respectively.
On base, corresponding balloon is provided with translucent cover; The next groove refluxing opening flow velocity is less than upper groove water filling port flow velocity.
Useful technique effect of the present utility model is: upper and lower two tanks are set, the next groove back-flow velocity is less than waterflood injection rate, water can constantly be piled up in the next groove, by constantly the rise political point view of proof " object is relative " of the next groove water yield, constantly cause balloon volume to increase and final explosion to water filling in the next groove by upper groove, by mode intuitively, the political point view of " quantitative change generation qualitative change " is proved; Solve political point view explanation uninteresting, abstract, the problem that students ' interest of study is poor.
Brief description of the drawings
Accompanying drawing 1 is this apparatus structure sketch.
In figure, 1 is that bearing, 2 is that upper groove, 3 is that magnetic valve, 4 is that support column, 5 is that base, 6 is that cross bar, 7 is that retainer ring, 8 is that the next groove, 9 is that translucent cover, 10 is that refluxing opening, 11 is that water pipe, 12 is that reflux pump, 13 is that balloon, 14 is collecting tank.
Detailed description of the invention
A kind of simple teaching experimental provision, referring to Fig. 1: comprise upper groove 2, support, balloon 13, retainer ring 7, the next groove 8, reflux pump 12, the support column 4 that outer wall is provided with ladder platform is vertically arranged on base 5, squeeze receptacle host cavity and upper groove 2 are all connected on support column 4 by cross bar 6, cross bar 6 one end are fixedly connected with retainer ring 7, the other end is connected to by bearing 1 on the ladder platform of support column 4 outer walls, and described squeeze receptacle host cavity and upper groove 2 coordinate and are assemblied in corresponding retainer ring 7 respectively; Upper groove 2 distributes up and down with the next groove 8, and upper groove 2 belows are provided with the water filling port that points to the next groove 8 inner chambers, and described water filling port is provided with magnetic valve 3; The next groove 8 lower ends are provided with delivery port and refluxing opening 10, and delivery port below is provided with balloon 13, and refluxing opening 10 is connected with collecting tank 14 by water pipe 11; Reflux pump 12 water inlet ends are placed in collecting tank 14, and water side is arranged on upper groove 2.
Cross bar 6 is connected to corresponding bearing 1 outer wall by the mode of welding; The internal diameter of two retainer rings 7 matches with the external diameter of the next groove 8 or upper groove 2 respectively.
On base 5, corresponding balloon 13 is provided with translucent cover 9; The next groove 8 refluxing opening 10 flow velocitys are less than upper groove 2 water filling port flow velocitys.
Upper and lower two tanks are set, liquid holding groove and topping up groove are fixed by revolute pair, can rotate in the horizontal direction, the next groove 8 back-flow velocities are less than waterflood injection rate, water can constantly be piled up in the next groove 8, by constantly the rise political point view of proof " object is relative " of the next groove 8 water yields, constantly make balloon 13 internal liquids that connect become many to water filling in the next groove 8 by upper groove 2, and finally cause balloon 13 explosions, by mode intuitively, the political point view of " quantitative change generation qualitative change " is proved; Solve the problem that political point view explanation is uninteresting, abstract, students ' interest of study is poor.
