Abstract
The utility model provides a buoyancy demonstration device for the physical teaching purpose, which belongs to a demonstration instrument for a physical teaching experiment, and structurally comprises a base, wherein vertical upright stanchions are symmetrically arranged on both sides of the base; lantern rings are in sleeve joint with the two upright stanchions; bottle pedestals are fixed on the lantern rings through connecting rods; a water storage bottle with a downward opening is arranged in the bottle pedestals; a water storage tank is also fixed on the base; the water storage tank is in the shape of a sand filter, and an upper opening of the water storage tank corresponds to the opening of the water storage bottle; a buoyant ball is arranged at the upper part of a bottleneck of the water storage tank; and the diameter of the buoyant ball is greater than that of the bottleneck. Compared with the prior art, the buoyancy demonstration device for the physical teaching purpose is characterized by reasonable design, simple structure, convenient use and the like, reduces the difficulty for the teaching of a teacher, and is helpful for students to understand and learn the physical buoyancy.
Description
Technical field
The utility model relates to the physics teaching experiment demonstration instrument, a kind of specifically physics teaching buoyancy demonstration device.
Background technology
In the middle school physical curriculum teaching, buoyancy phenomenon is the key content of physics course, the reason that liquid buoyancy produces and influence the liquid buoyancy factor be the difficult point of imparting knowledge to students all the time, the teacher generally can come aided education by the experiment of demonstration physics buoyancy in explanation, usually all be to adopt floatable object is set in water tank, but the existing experimental apparatus of process that buoyancy produces and reason can't intuitively be shown to the student, and Direct observation also express not vivid, the student understands relatively difficulty to it, causes relatively poor demonstration effect.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provide a kind of simple in structure, show physics teaching buoyancy demonstration device intuitively.
The technical solution of the utility model realizes in the following manner, this physics teaching buoyancy demonstration device, its structure comprises base, the base symmetria bilateralis is provided with vertical posts, equal symmetry is socketed with the collar in two vertical rods, the described collar is fixed with the bottle holder by connecting rod, be placed with downward opening water storage bottle in the bottle holder, also be fixed with water storage box on the base, described water storage box is the hourglass shape and its upper end open is corresponding with the water storage bottle opening, the bottleneck top of water storage box is provided with buoyant spheres, and the diameter of described buoyant spheres is greater than the bottleneck diameter.
Described water storage box is a transparent water tank.
The water storage box bottom has outlet valve.
The beneficial effect that the utility model is compared with prior art produced is:
Physics teaching of the present utility model has characteristics such as simple in structure, easy to use, demonstrating visual with the buoyancy demonstration device, reason and the process that buoyancy produces directly can be showed the student, aided education, demonstrate respond well, and can reuse, also reduced simultaneously the difficulty that the teacher teaches, helped understanding and the study of student physics buoyancy.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, vertical rod, 2, the collar, 3, connecting rod, 4, water storage bottle, 5, the bottle holder, 6, bottle cap, 7, buoyant spheres, 8, water storage box, 9, outlet valve, 10, base.
Embodiment
Below in conjunction with accompanying drawing physics teaching of the present utility model is done following detailed description the in detail with the buoyancy demonstration device.
As shown in Figure 1, this physics teaching buoyancy demonstration device, its structure comprises base 10, base 10 symmetria bilateralis are provided with vertical posts 1, equal symmetry is socketed with the collar 2 in two vertical rods 1, the described collar 2 is fixed with bottle holder 5 by connecting rod 3, be placed with downward opening water storage bottle 4 in the bottle holder 5, also be fixed with water storage box 8 on the base 10, described water storage box 8 is the hourglass shape and its upper end open is corresponding with water storage bottle 4 openings, the bottleneck top of water storage box 8 is provided with buoyant spheres 7, and the diameter of described buoyant spheres 7 is greater than the bottleneck diameter.Described water storage box 8 is a transparent water tank, has outlet valve 9 in the water tank bottom.
When using the utility model demonstration buoyancy phenomenon, at first Open Side Down is placed in the bottle holder 5 with water storage bottle 4, open the bottle cap 6 of opening part and the outlet valve 9 of water storage box 8, this is that water flows down in water storage bottle 4, buoyant spheres 7 can not floated, illustrate that the water in the water storage box 8 this moment produce buoyancy to buoyant spheres 7, buoyant spheres is only born water in the water storage box 87 this moments to the downward pressure of buoyant spheres 7.
Close the outlet valve 9 of water storage box 8, buoyant spheres 7 floats up after water covers bottleneck, and then the explanation buoyancy of water is greater than the gravity of buoyant spheres 7, and is directly perceived and the production process of expressing buoyancy of image is easy to Physical Education Teacher's teaching.
Claims (3)
1. physics teaching buoyancy demonstration device, comprise base, the base symmetria bilateralis is provided with vertical posts, it is characterized in that equal symmetry is socketed with the collar in two vertical rods, the described collar is fixed with the bottle holder by connecting rod, is placed with downward opening water storage bottle in the bottle holder, also be fixed with water storage box on the base, described water storage box is the hourglass shape and its upper end open is corresponding with the water storage bottle opening, and the bottleneck top of water storage box is provided with buoyant spheres, and the diameter of described buoyant spheres is greater than the bottleneck diameter.
