Abstract
Disclosed is a buoyancy demonstration device used for physics teaching in high school, which is composed of a big tank, a small tank, an inner communicating pipe, a control valve, an outer communicating pipe, a support, a float and a pipe end fixing device. The big tank is disposed on the support, the small tank is disposed at the central position in the big tank, and the float is disposed at the upper end of the small tank. The inner communicating pipe is disposed at one side of a bottom plate of the big tank by communicating means, and the other end of the inner communicating pipe is communicated into the small tank by inserting means from a bottom plate of the small tank. A control valve which controls on or off of the inner communicating pipe is disposed at the central position of the inner communicating pipe. The outer communicating pipe is disposed in the bottom plate of the small tank by inserting way, and the pipe end fixing device is disposed at the upper end of one side of the big tank for locating and fixing the outer end of the outer communicating pipe. The utility model has advantages of simple whole structure and convenient operation and use, both the big tank and the small tank adopt transparent material, so the demonstration intuition is good.
Description
Technical field:
The utility model relates to teaching and uses teaching aid, relates in particular to physics teaching in secondary school buoyancy demonstration device.
Background technology:
Object is immersed in the liquid, and six faces of object all can be subjected to the pressure of liquid, and all around four pressure that face bore equate, and pressure up and down is often unequal, and following pressure will form the buoyancy to object greater than top pressure.The phenomenon of this object come-up can illustrate the principle that buoyancy produces, but under the situation of the device of this buoyancy phenomenon not being demonstrated, the student is inadequately intuitively for the understanding of this buoyancy phenomenon.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of physics teaching in secondary school buoyancy demonstration device is provided, and can intuitively and easily the buoyancy phenomenon of object in liquid be demonstrated, and helps student's understanding.
Physics teaching in secondary school described in the utility model buoyancy demonstration device includes tank, little tank, interior communicating pipe, by-pass valve control, outer communicating pipe, support, float and pipe end stationary installation and forms.Said support is a support member of the present utility model, and integral body is framed structure, as ground connection support member of the present utility model.On said support, be provided with tank.Said tank, the water tank of the transparent form of saying so on the whole.Position placed in the middle in said tank is provided with little tank.Said little tank also is the water tank of a transparent form.Upper end at said little tank is provided with float.In base plate one side of said tank, be provided with interior communicating pipe with the form that feeds, the other end of said interior communicating pipe then from the base plate of little tank, is passed in the little tank with the form of inserting.The middle position of communicating pipe in said is provided with the by-pass valve control of controlling interior communicating pipe conducting or closing usefulness.At the base plate place of said little tank, also be to be provided with outer communicating pipe with the form of inserting, just the inner of said outer communicating pipe is arranged in the little tank, and the outer end of outer communicating pipe is arranged on the outside of tank then as free end.The outer end of outer communicating pipe is lowered to below the height of little tank, liquid in the little tank can be discharged, when doing to stop to discharge, then the outer end of outer communicating pipe can be fixed on the side upper end of tank.That is to say that the side upper end at tank is provided with the pipe end stationary installation, is used for positioning the outer end of outer communicating pipe fixing.
Physics teaching in secondary school described in the utility model buoyancy demonstration device, one-piece construction is simple, and is easy for operation, and tank and little tank all adopt transparent material to make, and the intuitive of demonstration is good.
Description of drawings:
Accompanying drawing 1 is the structural representation of physics teaching in secondary school described in the utility model with the buoyancy demonstration device.The outer communicating pipe 6-support 7-float 8-end of communicating pipe 4-by-pass valve control 5-stationary installation in the little tank 3-of 1-tank 2-
Embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: physics teaching in secondary school described in the utility model buoyancy demonstration device includes tank 1, little tank 2, interior communicating pipe 3, by-pass valve control 4, outer communicating pipe 5, support 6, float 7 and pipe end stationary installation 8 and forms.Said support 6 is support members of the present utility model, and integral body is framed structure, as ground connection support member of the present utility model.On said support 6, be provided with tank 1.Said tank 1, the water tank of the transparent form of saying so on the whole.Position placed in the middle in said tank is provided with little tank 2.Said little tank 2 also is the water tank of a transparent form.In the upper end of said little tank 2, be provided with float 7.In base plate one side of said tank 1, be provided with interior communicating pipe 3 with the form that feeds, the other end of said interior communicating pipe 3 then from the base plate of little tank 2, is passed in the little tank 2 with the form of inserting.The middle position of communicating pipe 3 in said is provided with the by-pass valve control 4 of controlling interior communicating pipes 3 conducting or closing usefulness.At the base plate place of said little tank 2, also be to be provided with outer communicating pipe 5 with the form of inserting, the inner of just said outer communicating pipe 5 is arranged in the little tank 2, and the outer end of outer communicating pipe 5 is arranged on the outside of tank 1 then as free end.The outer end of outer communicating pipe 5 is lowered to below the height of little tank 2, liquid in the little tank 2 can be discharged, when doing to stop to discharge, then the outer end of outer communicating pipe 5 can be fixed on the side upper end of tank 1.That is to say that the side upper end at tank 1 is provided with pipe end stationary installation 8, is used for positioning the outer end of outer communicating pipe 5 fixing.Physics teaching in secondary school described in the utility model buoyancy demonstration device, one-piece construction is simple, and is easy for operation, and tank 1 and little tank 2 all adopt transparent material to make, and the intuitive of demonstration is good.
