The utility model is not only simple in structure, small, convenient to use can be used for improving student's interest in learning and the enthusiasm that excites student oneself to probe into study in addition, play student yi xue and like and teacher easily to teach the effect of easily awarding.
Description
Technical field
This utility model relates to physics teaching apparatus field, is specially a kind of water heading experimental provision.
Background technology
Physics is one and contacts close subject with life, life has physics everywhere, water heading experiment utilizes bernoulli principle (the local pressure that rate of flow of fluid is big is little) to develop, but present teaching equipment is simple, interest is the strongest, student learning interest cannot be improved and excite student resource Inquiry Learning enthusiasm, and operating easy not.
Utility model content
The purpose of this utility model is to provide a kind of water heading experimental provision, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of water heading experimental provision, including support, bucket, water conduction hose, rubber stopper and soft air-guide pipe, it is placed with bucket on described support, and bucket is fixed on support by iron wire, the outside of described bucket is fixed with pin, the upper end of bucket is fixed with rubber stopper, valve inside and three ports valve doors it are fixed with on described rubber stopper, described three ports valve doors are connected with two hard tubes respectively by two water conduction hoses, hard tube is vertically fixed on support, and the top of support is placed with baton round, described valve inside is connected with inflator by soft air-guide pipe.
Preferably, described support is L-shaped.
Preferably, one end of described iron wire is fixed on support, and the other end of iron wire is flexibly connected with support by iron nail.
Preferably, the lower end of described three ports valve doors connects the sebific duct having an a length of 50cm, and the bottom of sebific duct is pointed.
Compared with prior art, the beneficial effects of the utility model are: this water heading experimental provision, by inflator, is pressurizeed in the inside of bucket, the water in bucket is made to pass through water conduction hose, finally discharge from the upper end of hard tube, by baton round jack-up, this apparatus structure is simple, low cost, it is simple to operation, it is prone to improve student learning interest, it is easy to teaching, by pin and iron wire, bucket is fixed, it is to avoid owing in bucket, the change of pressure makes bucket fly up simultaneously, thus life is threatened safely, it is ensured that the safety of this device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of rubber stopper of the present utility model.
In figure: 1, support, 2, pin, 3, bucket, 4, iron wire, 5, water conduction hose, 6, hard tube, 7, baton round, 8, rubber stopper, 9, soft air-guide pipe, 10, inflator, 11, valve inside, 12, three ports valve doors.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1 and Fig. 2，A kind of technical scheme of this utility model offer: a kind of water heading experimental provision，Including support 1、Bucket 3、Water conduction hose 5、Rubber stopper 8 and soft air-guide pipe 9，Bucket 3 it is placed with on support 1，Support 1 is L-shaped，And bucket 3 is fixed on support 1 by iron wire 4，One end of iron wire 4 is fixed on support 1，The other end of iron wire 4 is flexibly connected with support 1 by iron nail，The outside of bucket 3 is fixed with pin 2，The upper end of bucket 3 is fixed with rubber stopper 8，Valve inside 11 and three ports valve doors 12 it are fixed with on rubber stopper 8，The lower end of three ports valve doors 12 connects the sebific duct having an a length of 50cm，And the bottom of sebific duct is pointed，Three ports valve doors 12 are connected with two hard tubes 6 respectively by two water conduction hoses 5，Hard tube 6 is vertically fixed on support 1，And the top of support 1 is placed with baton round 7，Valve inside 11 is connected with inflator 10 by soft air-guide pipe 9.
Operation principle: inflated in bucket 3 by inflator 10, the pressure in bucket 3 is made to increase, then the water in bucket 3 is forced out by three ports valve doors 12, water is flowed out by water conduction hose 5 and hard tube 6, and form two vertical water columns, along with the pressure inside bucket 3 constantly increases, water column sprays higher and higher, again two baton rounds 7 are put into above two water columns respectively, baton round 7 stands on water column, during water column impact baton round 7, water beam spreading is opened, baton round 7 is held as Folium Nelumbinis, it is not allowed to fall down, here it is utilize the bernoulli principle in physics, in high-velocity flow, pressure is less than the pressure of current ambient atmosphere, baton round 7 is clustered round by surrounding atmosphere pressure, again by the towing force of water column, so will not slide, can only screw body without a break.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and improvement thereof, all should contain in protection domain of the present utility model.
