Abstract
A novel cartesian diver comprises a transparent tube, an air pressure bag on the top of the transparent tube, and a cartesian diver arranged in the transparent tube. wherein the cartesian diver comprises a test tube, a water tube, a plug, a counterweight nut and a fine tube, wherein the plug is plugged in the open end of the test tube, the fine tube penetrates through the plug and is connected to the water tube of the test tube, and the counterweight nut is installed at the outer end of the fine tube. The novel cartesian diver is reasonable in structural design, convenient and easy for operation, easy for material accessing, and simple for production. The novel cartesian diver makes the experiment of cartesian diver obvious and easy for observation.
Description
Technical field
The utility model relates to a kind of experiment teaching aid, especially a kind of Cartesian diver for experiment.
Background technology
Cartesian diver is a kind of experiment teaching aid of classics, is used for demonstrating the relation of buoyancy and pressure in the mechanics, in the physics teaching demonstration of each school, various Cartesian divers, shape and effect also each not just as.Common Cartesian diver be with two small one and large one bottles as the basic operation thing, the small bottle body of an open-ended is injected a part of water, have the stopper of through hole to tighten with middle then, again tubule is screwed in the through hole of stopper.Then small bottle body is put into the big bottle that injects water, seal the openning of big bottle one end, by pushing the body of big bottle, change the pressure in the big bottle, hydraulic pressure is gone in the small bottle body, thereby the weight of change small bottle body self realizes the sink-float of small bottle body.But the method is for the DeGrain of experiment, situation instability.Can shine into ripples fluctuation in the big bottle when pushing big bottle, thereby influence the stable of small bottle body and be unfavorable for observation, it is limited that next is extruded the water yield of small bottle body into, and across the water of big bottle, thereby be unfavorable for observing the relation of pressure and SEA LEVEL VARIATION.So we need a reliable and stable experimental provision that is beneficial to observation to demonstrate this phenomenon.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of energy to be used for the experiment teaching aid Cartesian diver of demonstration mechanics buoyancy and pressure relation, and its project organization is reasonable, is easy to the observation experiment phenomenon, and is convenient to operation.Satisfied in the experiment and will aspire for stability, be easy to the requirement of observing, operating.
The utility model solves the technical scheme that its technical matters adopts: this novel Cartesian diver, comprise transparent pipe, transparent pipe top is provided with the air pressure capsule, be provided with Cartesian diver in the transparent pipe, Cartesian diver comprises test tube, water pipe, stopper, counterweight nut and tubule, stopper is blocked in the openend of test tube, and tubule passes on the water pipe that stopper is connected test tube, and the counterweight nut is installed in the outer end of tubule.Wherein transparent pipe adopts elongated structure, in transparent pipe, add clear water, Cartesian diver is put into water, and Cartesian diver also adopts elongated water pipe, by the counterweight nut one end of test tube is sunk, make it in water, be vertical state, more be conducive to observe the water level in the Cartesian diver, press the air pressure capsule on top during use, simple to operation, display effect is obvious, is convenient to observe.
Transparent pipe bottom is provided with base.Transparent pipe is firmly being stood, be convenient to put.
Be provided with buoy in the water pipe.Help to observe the water level in the water pipe like this.
The effect that the utility model is useful is: the utility model reasonable in design, and simple to operation, draw materials easily, make simply, the leafhopper experiment is shown obviously, be easy to observe.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 presses down the air pressure capsule for the utility model.
Description of reference numerals: transparent pipe 1, air pressure capsule 2, test tube 3, water pipe 4, stopper 5, counterweight nut 6, tubule 7, buoy 8, base 9.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This novel Cartesian diver, comprise transparent pipe 1, transparent pipe 1 bottom is provided with base 9, transparent pipe 1 top is provided with air pressure capsule 2, is provided with Cartesian diver in the transparent pipe 1, and Cartesian diver comprises test tube 3, water pipe 4, stopper 5, counterweight nut 6 and tubule 7, stopper 5 is blocked in the openend of test tube 3, tubule 7 passes on the water pipe 4 that stopper 5 is connected test tube 3, is provided with buoy 8 in the water pipe 4, and counterweight nut 6 is installed in the outer end of tubule 7.
In teaching demonstration, press air pressure capsule 2, when the pressure in the transparent pipe 1 increased, the air in the Cartesian diver was compressed, and water enters water pipe 4 from tubule 7, buoy 8 come-ups in the water pipe 4, whole Cartesian diver weight increases, and Cartesian diver sinks.When decontroling air pressure capsule 2, the pressure in the pipe reduces, and water flows out by tubule 7 from water pipe 4, and buoy 8 descends, Cartesian diver weight saving come-up.
The utility model reasonable in design, simple to operation, draw materials easily, make simply, the leafhopper experiment is shown obviously, be easy to observe.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
