Description
Technical field
This utility model is related to bernoulli ball float.
Background technology
Bernoulli Jacob passes through numerous experiments, it was found that " boundary layer skin effect "：When fluid velocity is accelerated, object and fluid
Pressure on the interface of contact can reduce, otherwise pressure can increase.The in honor of contribution of this scientist, this discovery are referred to as
" Bernoulli effect ".Bernoulli effect is applied to including all fluids including gas, is basic when fluid makees steady flow
One of phenomenon, reflects the relation of the pressure of fluid and the relation of flow velocity, flow velocity and pressure：The flow velocity of fluid is bigger, and pressure is got over
It is little；The flow velocity of fluid is less, and pressure is bigger., now in society, Bernoulli effect is widely used, such as this：Aircraft wing, spray
Day with fog, petrolic carburator, screw in ball game etc..In order to further study to Bernoulli effect, with
By which extensively, apply to depth, need to meet the high characteristic of simple, inexpensive and accuracy with the device being tested, and show
Complicated or accuracy is relatively low mostly for some structures.
The content of the invention
The purpose of this utility model is to provide a kind of simple, bernoulli floating ball device that low cost and accuracy are high.
The technical scheme for realizing above-mentioned purpose is：
A kind of bernoulli ball float, carries ball float, including：Circular cylindrical cavity, four pieces of fixed plates, four escape pipes and four wind

Four pieces of fixed plates are equally spaced fixed on the medial wall of the circular cylindrical cavity by horizontal circumferencial direction；
Four blower fans are separately fixed in four pieces of fixed plates, and respective air outlet is upward；
Four escape pipes vertically connect the air outlet of four blower fans respectively, and lean out the cylindrical cavity
The top of body；
Carry the ball float in the top of the escape pipe.
In above-mentioned bernoulli ball float, four escape pipes include two fixed escape pipes and two it is adjustable go out
Trachea；
Connected by fixed cover between the fixed escape pipe and the adjustable escape pipe and the corresponding blower fan
It is fixed；
One is fixed between the fixed escape pipe and the adjustable escape pipe and the air outlet of the corresponding blower fan
Layer backstop；
The bottom of the fixed escape pipe is cased with air guiding sleeve, and the air guiding sleeve is contained in the fixed cover；
The bottom of the adjustable escape pipe is cased with spheric seat；
The first half of the spheric seat is cased with damping ring；
The lower half of the spheric seat is cased with gland.
In above-mentioned bernoulli ball float, the circular cylindrical cavity includes：
Base plate；

The beneficial effects of the utility model are：Simple combination of this utility model by parts such as blower fan, escape pipes, accurately
Realize the test of Bernoulli effect.Meanwhile, by the design of adjustable escape pipe, the angle of escape pipe can be adjusted to see
The change of bead is examined, Bernoulli effect, and the characteristic with low cost is fully understood from.
Description of the drawings
Fig. 1 is the cut-away view of bernoulli ball float of the present utility model；
Fig. 2 is the top view of bernoulli ball float of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, bernoulli ball float of the present utility model, including：1, four pieces of fixed plates 2, four of circular cylindrical cavity
Individual escape pipe 3 and four blower fans 4.3 points of four escape pipes are two fixed escape pipes 31 and two adjustable escape pipes 32.
Circular cylindrical cavity 1 includes：Base plate 11, side plate 12, panel 13, maintenance door, multiple probes 14 and electric appliance control box 15.
Side plate 12 is vertically fixed on base plate 11, and is formed a circle.Panel 13 is fixed at the top of side plate 12, and holds escape pipe
3 lean out.Maintenance door is arranged on 12 side of side plate.Each probe 14 is arranged on the side of side plate 12, and electric appliance control box 15 is fixed on bottom
On plate 11, and electrically connect probe 14 and blower fan 4.
Four pieces of fixed plates 2 are equally spaced fixed on the medial wall of circular cylindrical cavity 1 by horizontal circumferencial direction, i.e., and adjacent two
It is in 90 degree between block fixed plate 2.
Four blower fans 4 are separately fixed in fixed plate 2, and each air outlet is vertical upward.
Four escape pipes 3 vertically connect the air outlet of four blower fans 4 respectively, and top is from the top of circular cylindrical cavity 1
Portion leans out and.4 air blast of blower fan, finally sprays from the mouth of pipe of escape pipe 3, for floating ball float.At ordinary times, the top of escape pipe 3
Carry ball float.
Connected by fixed cover 5 between fixed escape pipe 31 and adjustable escape pipe 32 and each self-corresponding blower fan 4
It is fixed.
One layer is fixed between the air outlet of fixed escape pipe 31 and adjustable escape pipe 32 and each self-corresponding blower fan 4
Backstop 6.
The bottom of fixed escape pipe 31 is cased with air guiding sleeve 7, and the air guiding sleeve 7 is contained in fixed cover 5.
The bottom of adjustable escape pipe 32 is cased with spheric seat 8, and the first half of spheric seat 8 is cased with damping ring 81, spheric seat 8
Lower half is cased with gland 82, so that adjustable escape pipe 32 can be rotated within the specific limits.
Ball float is placed on 3 overhead of escape pipe of jet upwards, and bead is acted on by three power：" erupt " in escape pipe 3
Air directed force F 1 upwards that ball is produced, buoyancy F2 of the air to bead, the gravity Mg of bead itself.According to bernoulli
Principle：The flow velocity of fluid is bigger, and pressure is less；The flow velocity of fluid is less, and pressure is bigger.Vertically arranged escape pipe 3 sprays upwards
In the airflow function region for going out, air pressure is less than around which, so bead is placed on above airduct, it can be basically stable at
In flow area, will not run to the high surrounding of pressure.Adjustable escape pipe 32 can be rotated, ball float situation is observed.
Above example is only for illustration of the utility model, rather than to restriction of the present utility model, relevant technical field
Technical staff, in the case of without departing from spirit and scope of the present utility model, various conversion or modification can also be made, because
The technical scheme of this all equivalent should also belong to category of the present utility model, should be limited by each claim.
