Abstract
The utility model discloses a buoyancy demonstration instrument which comprises a transparent container (1), wherein water (2) is contained in the container (1). The utility model is characterized in that a buoy (3) is arranged in the container (1) and comprises a ball float (4) with a cavity; a balancer (6) is integrally arranged at the lower part of the ball float (4); a water inlet and outlet pipe (5) penetrates through the balancer (6) to be communicated with the ball float (4); a cylinder is arranged at the upper part of the ball float (4) and is communicated with an air inlet and outlet pipe (7), and the other end of the air inlet and outlet pipe (7) is communicated with the ball float (4); an air inlet and outlet (11) is arranged at the upper part of the cylinder (9); and a first electromagnetic valve (8) and a second electromagnetic valve (10) are respectively arranged at the lower end of the air inlet and outlet (11) and the air inlet and outlet pipe (7). By adopting the structure, the cylinder (9), the first electromagnetic valve (8) and the second electromagnetic valve (10) can be used for exhausting or sucking air according to the requirements, so that the purpose of visualized learning and good receiving effect of the students can be achieved.
Description
Technical field
The utility model relates to a kind of teaching equipment, relates in particular to a kind of buoyancy demonstration instrument.
Background technology
The teacher is immersed in the object in the liquid when professor's buoyancy one joint, can be subjected to gravity and buoyancy function, and when buoyancy during greater than gravity, object recovers on liquid side; When buoyancy equaled gravity, object floated on a liquid; When buoyancy during less than gravity, object sinks in liquid.Adopt this teaching methods more directly perceived, should not allow the student accept, the effect of influence study.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and directly perceived, the student learns the good buoyancy demonstration instrument of reception.
The technical solution of the utility model is a kind of buoyancy demonstration instrument, it comprises transparent container 1, fill water 2 in the described container 1, it is characterized in that: be provided with sink-float mark 3 in the described container 1, described sink-float mark 3 comprises the ball float 4 of a band cavity, the bottom one of described ball float 4 be provided with weight device 6, one water inlet pipe and water outlet pipe 5 passes described weight device 6 and communicates with described ball float 4, the top of described ball float 4 is provided with cylinder 9, described cylinder 9 communicates with a turnover tracheae 7, the other end of described turnover tracheae 7 communicates with described ball float 4, the top of described cylinder 9 is provided with air inlet/outlet 11, is respectively equipped with first solenoid valve 8 and second solenoid valve 10 on the lower end of described air inlet/outlet 11 and the described turnover tracheae 7.
The technical solution of the utility model can also be that described cylinder 9, first solenoid valve 8 and second solenoid valve 11 are controlled by telepilot.
The beneficial effects of the utility model are by be provided with sink-float mark 3 in described container 1, described sink-float mark 3 comprises the ball float 4 of a band cavity, the bottom one of described ball float 4 be provided with weight device 6, make its center of gravity on the lower side, one water inlet pipe and water outlet pipe 5 passes described weight device 6 and communicates with described ball float 4, the top of described ball float 4 is provided with cylinder 9, described cylinder 9 communicates with a turnover tracheae 7, the other end of described turnover tracheae 7 communicates with described ball float 4, the top of described cylinder 9 is provided with air inlet/outlet 11, be respectively equipped with first solenoid valve 8 and second solenoid valve 10 on the lower end of described air inlet/outlet 11 and the described turnover tracheae 7, like this, cylinder 9, first solenoid valve 8 and second solenoid valve 10 can carry out exhaust or air inlet as requested, and when being vented to when a certain amount of, sink-float mark 3 sinks; When air inflow when a certain amount of, when the buoyancy of sink-float mark 3 equated with gravity, whose somewhere sink-float mark 3 will rest on, when air inflow further increased, when the buoyancy of sink-float mark 3 equated greater than gravity, sink-float mark 3 will float; Having reached the student like this learns both directly perceived by the good purpose of reception.
