Description
Technical Field
The utility model relates to the technical field of teaching aids, in particular to a teaching aid for exploring liquid pressure.
Background
In physics, pressure and pressure are two different physical quantities. Pressure is the force perpendicular to a plane, in newtons; pressure is the pressure experienced per unit area in newtons per square meter, (also known as pascals). There is pressure, of course, within the liquid. The pressure inside the liquid is related to the density and depth of the liquid.
In the present teaching, the theory that liquid pressure changes along with the degree of depth change is derived through the pressure formula usually, does not have audio-visual teaching aid and teachers 'teaching and student's understanding, is unfavorable for the teacher to develop the teaching work, and the student also can audio-visually watch the show of this principle when studying in addition, is unfavorable for the student to the grasp of this principle.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a teaching aid for researching liquid pressure, and solves the problems in the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a study hydraulic pressure's teaching aid, includes the base, be equipped with the water tank on the base, four sides of water tank are equipped with pressure indicating device respectively, the water tank lower extreme is equipped with the drain pipe, the drain pipe tip is equipped with the end and presss from both sides.
As a further improvement of the utility model, the pressure indicating device comprises a supporting rod, the supporting rod is fixedly connected with the base, a limiting cylinder is arranged on the supporting rod, a pressure testing hole is arranged on the water tank, a rubber film is arranged at one end, positioned outside the water tank, of the pressure testing hole, an indicating rod is arranged in the middle of the rubber film, and the other end of the indicating rod is arranged inside the limiting cylinder.
As a further improvement of the utility model, four side surfaces of the side part of the water tank at the same height are respectively provided with a pressure test hole, and the side surfaces of one side of the water tank are provided with pressure test holes at different heights.
Compared with the prior art, the utility model has the following beneficial effects: the pressure indicating device is arranged around the water tank, so that the condition that the pressure changes along with the depth can be visually displayed, students can visually observe or manually test in person, and the students can be helped to better understand the principle; the utility model is provided with the drain pipe and the flow stopping clip, thereby being convenient to use; the utility model can assist teachers in teaching and assist teachers in developing teaching work.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model provides a study hydraulic pressure's teaching aid, includes base 1, be equipped with water tank 2 on the base 1, 2 four sides of water tank are equipped with pressure indicating device respectively, 2 lower extremes of water tank are equipped with drain pipe 3, 3 tip of drain pipe are equipped with and only flow clamp 4.
The pressure indicating device comprises a supporting rod 5, the supporting rod 5 is fixedly connected with the base 1, a limiting barrel 6 is arranged on the supporting rod 5, a pressure testing hole 7 is formed in the water tank 2, one end, located outside the water tank 2, of the pressure testing hole 7 is provided with a rubber film 8, an indicating rod 9 is arranged in the middle of the rubber film 8, a scale mark is arranged on the indicating rod 9, and the other end of the indicating rod 9 is arranged inside the limiting barrel 6.
Four side faces of the side face of the water tank 2 at the same height are respectively provided with a pressure test hole 7, and the side faces of one side of the water tank 2 are provided with the pressure test holes 7 at different heights.
The working principle of the present invention is explained as follows:
to the inside water injection of water tank 2, liquid pressure can be ejecting with rubber film 8, and then drives indicator bar 9 and remove to the outside, and indicator bar 9 removes in spacing section of thick bamboo 6, alright carry out the reading through the scale mark that is equipped with on the indicator bar 9, and then shows the pressure of the different degree of depth, makes the principle that "pressure changes along with the degree of depth change" more directly perceived.
After use, the water in the water tank 2 can be discharged through the water discharge pipe 3 by opening the flow stop clip 4.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
