Technical field

The invention belongs to a kind of instruments used for education, it is mainly used for describing the experimental provision of level throw motion.

Background technique

Level throw motion needs to describe the track of its movement by Freehandhand-drawing, when correctly depicting track can find out that object is flat to be thrown Initial velocity, to further probe into laws of motion.The equipment that usual laboratory provides needs high-speed camera shooting is flat to throw The motion profile of object, this is difficult to accomplish in the general school of condition.For this purpose, the experiment dress of one simple level throw motion of design It sets.

Summary of the invention

To solve the above problems, the present invention provides a kind of experimental provision of level throw motion.

The present invention is achieved through the following technical solutions:

A kind of experimental provision of level throw motion, including water column generation device and drawing apparatus two parts, the drawing apparatus is the bottom of by Seat and panel normal thereto composition, and the attached waterproof graph paper of the panel, preferably sulfuric acid graph paper；The water column generation device It is fixed on panel upper left side somewhere；The water column generation device includes wide-mouth bottle, glass tube, nozzle；During the glass tube includes Empty glass straight tube A, hollow right-angled glass pipe B；And the hollow glass straight tube A and hollow right-angled glass pipe B is inserted into across bottle stopper In wide-mouth bottle, to keep the hollow glass straight tube A air inlet smooth, its underpart meets a nozzle 1, preferably 0.5mm；The hollow right angle Glass tube B water outlet one nozzle 2 of termination, preferred nozzle internal diameter 1.55mm.

As a further optimization solution of the present invention, when demonstration, it is preferably equipped with the water of color in the wide-mouth bottle, passes through water It is done if stream is described on graph paper, its rule of horizontal projectile movement can be studied.

As a further optimization solution of the present invention, the hollow glass straight tube A and hollow right-angled glass pipe B are in wide-mouth bottle In there are differences in height for part.

As a further optimization solution of the present invention, the external structure that the hollow glass straight tube A is presented is vertical structure； The external structure that the hollow right-angled glass pipe B is presented is L-type structure.

Compared with prior art, the beneficial effects of the present invention are: the novel demonstrating level throw motion that can be vivid Rule, so that studying rule of horizontal projectile movement brings many conveniences.

Specific embodiment

Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:

As shown in Figs. 1-2, a kind of experimental provision of level throw motion, including water column generation device (2) and drawing apparatus (1) two Point, the drawing apparatus (1) is made of pedestal (1-1) and panel normal thereto (1-2), and the panel (1-2) attached waterproof Graph paper, preferably sulfuric acid graph paper；The water column generation device (2) is fixed on the upper left side somewhere panel (1-2)；The water column produces Generating apparatus (2) includes wide-mouth bottle (2-1), glass tube (2-2), nozzle (2-3)；The glass tube (2-2) includes that hollow glass is straight Pipe A(2-2-1), hollow right-angled glass pipe B(2-2-2)；And the hollow glass straight tube A(2-2-1) and hollow right-angled glass pipe B (2-2-2) is passed through in bottle stopper insertion wide-mouth bottle (2-1), to make the hollow glass straight tube A(2-2-1) air inlet is smooth, its underpart Meet a nozzle 1(2-3-1), preferably 0.5mm；The hollow right-angled glass pipe B(2-2-2) one nozzle 2(2-3-1 of water outlet termination), Preferred nozzle internal diameter 1.55mm；The water of color is preferably equipped in the wide-mouth bottle (2-1), if describing on graph paper by water flow It does, its rule of horizontal projectile movement can be studied；The hollow glass straight tube A(2-2-1) and hollow right-angled glass pipe B(2-2-2) There are differences in height for part in wide-mouth bottle (2-1)；The hollow glass straight tube A(2-2-1) present external structure be vertical Structure；The hollow right-angled glass pipe B(2-2-2) present external structure be L-type structure.

The utility model device in this embodiment, when demonstration, is preferably equipped with the water of color, by water column generation device (2) it is fixed on the upper left side somewhere panel (1-2), is done if being described on graph paper by water flow, its level throw motion can be studied Rule.It is inverted after wide-mouth bottle (2-1) canned suitable quantity of water.When not demonstrating, hollow glass straight tube A(2-2-1) lower section finger or its His soft object blocks its air inlet, when demonstration, takes soft object away or decontrols finger, since top port is communicated with atmospheric pressure, the pressure beginning It is equal to atmospheric pressure eventually, due to hollow glass straight tube A(2-2-1) and hollow right-angled glass pipe B(2-2-2) there are difference in height, liquid for pipe Face drops to hollow glass straight tube A(2-2-1) before mouth the top, difference in height is constant, it is known that the water column of nozzle (2-3) outflow is to hold Continue it is stable, convenient for followed by description.

The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle It is fixed.
