Description
Technical field
The utility model relates to a kind of apparatus for demonstrating, particularly a kind of buoyancy demonstrating device.
Background technology
Physics Course teaching in, buoyancy phenomenon is one of key content of Physics Course, and how liquid buoyancy produces, its buoyancy Producing reason and affect liquid buoyancy factor be all the time impart knowledge to students difficult point.If can not better be displayed, only simple by explanation, student is difficult to better understand principle wherein, and therefore teacher is when explaining, and generally can carry out aided education by the experiment of physics floating force.Usually be all adopt in water tank, arrange floatable object, but because the speed of buoyancy production process is uncontrollable, cause existing experimental apparatus by buoyancy production process and reason intuitively to showing, student cannot can not be allowed better to observe and understand, cause teaching efficiency to get half the result with twice the effort.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, there is provided one buoyancy phenomenon can better be demonstrated out, for the buoyancy that student estimates and more different floatation test article are suffered in water, can monitor the buoyancy demonstrating device of the buoyancy value of buoyancy bead in different liquids.
To achieve these goals, the technical solution adopted in the utility model is such: buoyancy demonstrating device of the present utility model, comprise demonstration cylinder body, the U-shaped structure of demonstration cylinder body, demonstration cylinder body internal cavity is divided into two, it it is pressure chamber, it is lower is aqua storage tank, between pressure chamber and aqua storage tank, seal pad is installed, in pressure chamber, turning axle is installed, turning axle is provided with air pressure valve, pressure chamber and aqua storage tank junction are provided with buoyant spheres, buoyant spheres lower surface is provided with pulling rope, between pulling rope with buoyant spheres, one is connected, pulling rope bottom is fixedly connected with demonstration cylinder body, pulling rope bottom is provided with executes refitting and puts, execute refitting to put and be horizontally installed on pulling rope, execute refitting to put lower surface press rods is installed, press rods is positioned at pulling rope both sides, press rods and execute refitting put between adopt and removably connect, press rods bottom is connected with a counter weight device through demonstration cylinder body.
Further, as a kind of concrete version, demonstration cylinder body described in the utility model adopts quartz crystal materials to make.
Further, as a kind of concrete version, aqua storage tank height described in the utility model is greater than pressure chamber height.
Further, as a kind of concrete version, be also provided with circulating water pipe in aqua storage tank described in the utility model, circulating water pipe one end extends in aqua storage tank, and its other end is connected with buoyant spheres.
Further, as a kind of concrete version, the built-in bead of buoyant spheres described in the utility model.
Further, as a kind of concrete version, described in the utility modelly execute refitting and put employing one gravity plate.
Compared with prior art, the utility model has the advantage of: buoyancy phenomenon can better be demonstrated out by this buoyancy demonstrating device, can for the buoyancy that student estimates and more different floatation test article are suffered in water, the buoyancy value of buoyancy bead in different liquids can be monitored, aided education demonstrating effect is very good, can reuse.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. demonstrate cylinder body; 2. aqua storage tank; 3. pressure chamber; 4. turning axle; 5. buoyant spheres; 6. pulling rope; 7. execute refitting to put; 8. press rods; 9. counter weight device.
Embodiment
