Specific embodiment
The embodiments of the present invention are described further with reference to the accompanying drawing:
As shown in Figure 1, Archimedes' principle described in the utility model verifies device, including pedestal 1, the top of pedestal 1
Storing has detection container 6 and filling container 13, fills pure water 5 in detection container 6 and filling container 13, detection container 6
Bottom is fixed with the first fixed pulley 4 and the second fixed pulley 3, and the first fixed pulley 4 is corresponding with the second fixed pulley 3 or so, detection container 6
Inside floating have a homogeneous regular floating body 10, the lateral wall of homogeneous rule floating body 10 is equipped with bisector 11, and homogeneous rule is floating
The bottom of body 10 is fixed with drawstring 7, and the top of pedestal 1 is fixed with support frame 8, be fixed on support frame 8 on the second fixed pulley 3
Under corresponding weight beam 9, the drawstring 7 sequentially passes through the first fixed pulley 4 and the second fixed pulley 3 is fixed on spring dynamometry
On the hook of meter 9.
In preferred embodiment: the top of pedestal 1 is equipped with detection container fixing groove and filling container fixing groove, detection container 6
It is seated in detection container fixing groove and filling container fixing groove respectively with filling container 13, in mobile the utility model Shi Keyou
Effect prevents detection container 6 and filling container 13 from sliding, convenient for the carrying of the utility model；Homogeneous rule floating body 10 is positive tetragonous
Column is respectively and fixedly provided with connecting rope 12 at the angle of bottom four of homogeneous rule floating body 10, and the other end of each connecting rope 12 connects with drawstring 7
Fixation is connect, makes the bottom stress of homogeneous regular floating body 10 more evenly；Detection container 6 and filling container 13 are transparent material, just
In student viewing verification process, increase students ' interest of study；The left and right sides of pedestal 1 is equipped with built-in handle 2, is convenient for this reality
With novel carrying.
In use, removing filling container 13, pure water 5 is filled into detection container 6, the half to homogeneous regular floating body 10
When immersing in the pure water 5 in detection container 6, stop filling, as shown in Fig. 2, regular floating body 10 homogeneous at this time by buoyancy, from
The pulling force of body gravity and connecting rope 12, and it is in equilbrium position, the pulling force size of connecting rope 12 and the registration of weight beam 9
Unanimously, therefore self gravity of the buoyancy F1 size equal to the registration of weight beam 9 plus homogeneous regular floating body 10 is calculated, again
Since the half of homogeneous regular floating body 10 immerses in pure water 5, pure water density p, displacement of volume V and acceleration of gravity can be passed through
G calculates the size of buoyancy F2 at this time, can verify that Archimedes' principle by comparing F1 and F2 size；Then, continue to
Pure water 5 is filled in detection container 6,4/5ths to homogeneous regular floating body 10 are immersed in the pure water 5 in detection container 6
When, stop filling, as shown in figure 3, at this point, in the above way calculating F1 again is compared verifying with F2；Then, continue to
Pure water 5 is filled in detection container 6, when homogeneous regular floating body 10 is totally immersed into the pure water 5 in detection container 6, is stopped
Filling, as shown in figure 4, at this point, in the above way calculating F1 again is compared verifying with F2.It can also make homogeneous regular floating body
10, which immerse other volumes, is verified, and is verified by multi-group data, to ensure the accuracy of Archimedes' principle.
Archimedes' principle described in the utility model verifies device, can verify to Archimedes principle, effectively swashs
Sent out the learning interest of student, can also allow student to do it yourself experimental verification, deepen memory, effectively facilitated student to Ah
The grasp of base Mead law knowledge point.
