Description
Technical field
This utility model is related to teaching aid technical field, especially relates to a kind of buoyancy teaching demonstration lifting buoy.
Background technology
Buoyancy phenomenon in the middle of life is not strange for student, but the curricula with regard to buoyancy always is
Emphasis in physics teaching and difficult point, generally under the guiding of teacher, drive student to recognize buoyancy presence in laboratory observation
Phenomenon and the principles of science.However, due to the limitation of Self-made Realia, universal demonstration teaching aid generally do not have good directly perceived,
Lively displaying function, buoyancy demonstration tests inadequate concrete image, is unfavorable for that student carries out Experimental Research by meticulous inspection, adjusts
Do not move the enthusiasm of student's participation, and the study desire of the thinking that beats one's brains, knowledge.
Utility model content
This utility model is directed to the deficiencies in the prior art, and technical problem to be solved is to provide a kind of buoyancy teaching demonstration
With lift buoy, the displaying buoyancy phenomenon that it can be directly perceived, lively as buoyancy teaching demonstration apparatus, can with mobilizing students in person
The enthusiasm start, playing an active part in, improves the enjoyment of experience buoyancy experiment, strengthens the study desire pursuing scientific knowledge.
This utility model is so that above-mentioned technical problem is addressed by the following technical programs.
A kind of buoyancy teaching demonstration lifting buoy, including plastic stent, counter weight base, balancing weight and nylon wire, plastics
The upper end of support is coated with umbrella nylon wire, and the mesh of nylon wire is 10 to 16, the lower end setting counter weight base of plastic stent, joins
It is provided with balancing weight in weight base.
Preferably, the upper end of plastic stent is provided with umbrella frame, nylon wire is coated on described umbrella frame.
Preferably, counter weight base is semiclosed shape cylinder.
Preferably, the lower end of plastic stent is provided with nut, the threaded nut of opening of counter weight base.
Preferably, balancing weight is circular metal plate, two to three balancing weights overlay in the inner chamber of counter weight base.
Preferably, counter weight base is plastic material structure.
The beneficial effects of the utility model：
1. lifting buoy is placed on such as tank etc. to be filled with water in utensil, is equipped with Bubbled stone simultaneously in tank and connects gas
Pump, air pump aerofluxuss produce bubble by Bubbled stone, and bubble is ceaselessly attached on the nylon wire of lifting buoy and passes through bubble buoyancy
Drive lifting buoy to float upwards, when emerging, constantly rupture loss of buoyance with bubble, rely on the gravity of balancing weight to make
With making lifting buoy submerged, thus move in circles and achieve the buoyancy phenomenon lecture experiment floating and settling, experiment effect
Fruit is intuitively visual, vivid, is easy to students meticulous inspection, probes into buoyancy phenomenon.
2. the experimentation of air pump aerofluxuss and Bubbled stone generation bubble, improves the enjoyment of experience buoyancy experiment, transfers
The enthusiasm that student takes action on one's own, plays an active part in, guiding students beat one's brains thinking, strengthen the study desire pursuing scientific knowledge.
3. overall structure is simplified compact, makes simple, easily, buoyancy phenomenon effect substantially, is conducive to popularization and application for demonstration.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure：1- plastic stent, 2- counter weight base, 3- balancing weight, 4- nylon wire, 5- nut.
Specific embodiment
Below by embodiment and combine accompanying drawing this utility model is described in detail.
A kind of this utility model as shown in Figure 1 buoyancy teaching demonstration lifting buoy, including plastic stent 1, counterweight bottom
Seat 2, balancing weight 3 and nylon wire 4, counter weight base 2 is chosen as plastic material structure, reduces deadweight.The upper end cladding of plastic stent 1
There is umbrella nylon wire 4, as a kind of embodiment, umbrella frame is set in the upper end of plastic stent 1, nylon wire 4 is coated on described
On umbrella frame.The mesh of nylon wire 4 is 10 to 16, so can effectively adhere to a large amount of bubbles.The lower end setting of plastic stent 1 is joined
Weight base 2, wherein, counter weight base 2 is semiclosed shape cylinder, and the lower end of plastic stent 1 is provided with nut 5, the opening of counter weight base 2
The threaded nut in mouth end 5.It is provided with balancing weight 3, as a kind of embodiment, balancing weight 3 is circular metal plate in counter weight base 2,
Two to three balancing weights 3 overlay in the inner chamber of counter weight base 2, to keep gravity balance.
This utility model is not limited to above-described preferred implementation, can be obtained based on those skilled in the art
The known technology known or using being caned the various modifications of equivalence replacement and the embodiment of change in prior art, every base
In spirit of the present utility model or technology design, should be included within protection domain of the present utility model.
