Abstract
The utility model discloses a buoyancy demonstration device applied to physics teaching. The buoyancy demonstration device comprises a water storage tank. A hollow buoyancy ball is arranged in the water storage tank. The buoyancy ball is provided with a water injection port and a water outlet. A water injection tank and a suction pump are arranged at the top of the water storage tank. The outlet end of the water injection tank is connected with the water injection port of the buoyancy ball. The water outlet of the buoyancy ball is connected with the inlet end of the suction pump. The outlet end of the suction pump is connected with the inlet end of the water injection tank. According to the utility model, the cause and the process of buoyancy generation can be directly demonstrated to students; the demonstration effect of teaching assisting is great; and the buoyancy demonstration device can be repeatedly used, and can help the students to deeply understand the physics phenomenon of buoyancy.
Description
Technical field
The utility model relates to a kind of junior middle school physics teaching servicing unit, relates in particular to a kind of buoyancy demonstration device for physical teaching purpose.
Background technology
In Physics Course teaching, buoyancy phenomenon is the key content of Physics Course, the reason that liquid buoyancy produces and affect liquid buoyancy factor be the difficult point of imparting knowledge to students all the time, teacher generally can carry out aided education by the experiment of physics floating force in explanation, conventionally be all to adopt floatable object is set in water tank, because the speed of buoyancy production process is uncontrollable, cause existing experimental apparatus buoyancy production process and reason intuitively cannot be shown to student, and it is not vivid directly to observe yet expression, student is more difficult to its understanding, causes the poor effect of giving lessons.
Utility model content
The purpose of this utility model provides a kind of simple in structure, the buoyancy demonstration device for physical teaching purpose that teaching efficiency is good with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises water storage box, in described water storage box, be provided with the buoyant spheres of hollow, in described buoyant spheres, be provided with water filling port and water delivering orifice, described water storage box top is provided with water injecting tank and suction pump, the endpiece of described water injecting tank is connected with the water filling port of described buoyant spheres, the water delivering orifice of described buoyant spheres is connected with the entrance point of described suction pump, and the endpiece of described suction pump is connected with the entrance point of described water injecting tank.
Particularly, described water storage box is transparent water storage box.
Further, described water storage box bottom offers draining valve.
As preferably, described water storage box top offers filler.
Particularly, the outlet of described water injecting tank is provided with stop valve.
The beneficial effects of the utility model are:
Reason and process that the utility model can produce buoyancy directly show student, and the good demonstration effect of aided education, can reuse, and is conducive to the profound understanding of student to the physical phenomenon of buoyancy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-filler, 2-water delivering orifice, 3-stop valve, 4-water injecting tank, 5-suction pump, 6-draining valve, 7-water filling port, 8-buoyant spheres, 9-water storage box.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises water storage box 9, in water storage box 9, be provided with the buoyant spheres 8 of hollow, in buoyant spheres 8, be provided with water filling port 7 and water delivering orifice 2, water storage box 9 tops are provided with water injecting tank 4 and suction pump 5, the endpiece of water injecting tank 4 is connected with the water filling port 7 of buoyant spheres 8, and the water delivering orifice 2 of buoyant spheres 8 is connected with the entrance point of suction pump 5, and the endpiece of suction pump 5 is connected with the entrance point of water injecting tank 4.
As shown in Figure 1, water storage box 9 is transparent water storage box, and water storage box 9 bottoms offer draining valve 6, and water storage box 9 tops offer filler 1, and the outlet of water injecting tank 4 is provided with stop valve 3.
Principle of work of the present utility model is as follows: after opening stop valve 3, water injecting tank 4 is owing to being subject to the impact of potential energy, liquid in water injecting tank 4 flows to the inside of buoyant spheres gradually, now in buoyant spheres 8, be full of gradually liquid, gravity increases and gradually to sinking, the stop valve of water injecting tank 43 is screwed and closed, start suction pump 5, liquid in buoyant spheres 8 is pumped to water injecting tank 4 gradually, buoyant spheres 8 is floated gradually, illustrate that water in water storage box 3 now produces buoyancy to buoyant spheres 8 and is greater than gravity, visual pattern reflect the process that buoyancy produces, be easy to teaching.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
