Description
Technical Field
The utility model relates to a middle school physics teaching technical field specifically is a hydrodynamics presentation device for middle school physics teaching.
Background
In the physics teaching of middle school, the problems about Bernoulli principle such as why the airplane flies up, why two approaching ships get closer and the river course with low flow rate is easier to dike up are encountered, and teachers can only tell students about the principle that the flow rate is higher and the pressure is lower, so that the students cannot feel intuitively.
Hydrodynamics is when teaching fluid to the effect of physical power, because lack the teaching aid of pertinence, most mr can only adopt the mode of explaining according to this to teach, relatively abstract, and the student lacks the chance of hands-on experiment again, and teacher and student hardly produce the interdynamic, and the quality of teaching is difficult to the assurance, and the student learns the degree of difficulty and is big partially, is unfavorable for the expansion of teaching work.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a hydrodynamics presentation device is used in middle school physics teaching to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a hydrodynamics demonstration apparatus for middle school physics teaching, comprising: tap connector, inlet tube, water column pipe, outlet pipe, tap connector rigid coupling on water tap, inlet tube one end connect the export at tap connector, the water column both ends adopt the rubber buffer sealed, and be provided with the connector on the rubber buffer, the connector and the inlet tube other end connection of water column front end, the connector and the play water piping connection of water column rear end, the water column pipe be the clear glass pipe, and the water column pipe superscript has the scale, the vertical water column top intermediate position of connecting at the level setting of water column pipe.
Furthermore, the water service pipes are provided with a plurality of groups, the connectors among the water service pipes are connected in series through pipelines, and the inner diameters of the water service pipes of the groups are gradually increased from front to back.
Furthermore, the front side and the rear side of the inside of the water pipe are provided with rectifying pieces.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a middle school is hydrodynamics presentation device for physical teaching, simple structure, design are ingenious, the subassembly is convenient, can give the student with audio-visual experience.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 2, the present invention provides a hydrodynamics demonstration apparatus for middle school physics teaching, comprising: tap connector 1, inlet tube 2, water service pipe 3, water column pipe 4, outlet pipe 5, 1 rigid coupling of tap connector on the tap, 2 one end of inlet tube connect the export at tap connector 1, 3 both ends of water service pipe adopt the rubber buffer 6 sealed, and be provided with connector 7 on the rubber buffer 6, the connector 7 and the inlet tube 2 other end connection of 3 front ends of water service pipe, the connector 7 and the play water pipe 5 of 3 rear ends of water service pipe are connected, water column pipe 5 be the clear glass pipe, and the water column pipe 5 superscript has the scale, 5 vertical connections of water column pipe are at 3 top intermediate positions of water service pipe that the level set up.
Furthermore, the water service pipes 3 are provided with a plurality of groups, the connectors 7 among the water service pipes 3 are connected in series through pipelines, and the inner diameters of the water service pipes 3 of the plurality of groups are gradually increased from front to back.
Furthermore, the front side and the rear side of the interior of the water service pipe 3 are both provided with a rectifying piece 8.
The working principle is as follows: the utility model provides a middle school is hydrodynamics presentation device for physics teaching, experiment 1 that can carry out is for using single water service pipe 3, through the delivery rate of adjusting tap, but the delivery rate is big more, the velocity of flow that flows through water service pipe 3 is then faster, but the water column height in water column pipe 4 is lower on the contrary, has verified that the velocity of flow is big more, pressure is little; experiment 2 can also be carried out by using a plurality of water pipes 3 with different diameters, opening the faucet without changing the water outlet speed, observing that the water pipe 3 with larger diameter has higher water column height in the water column pipe 4 at the upper end because the water quantity flowing out of the faucet in unit time is constant, the larger the diameter of the water pipe 3 is, the larger the sectional area is, the smaller the flow speed of the water flowing in unit time is, and the higher the range of water column generated by the smaller range of flow speed is, the smaller the flow speed is, the larger the pressure is.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
