Abstract
The utility model discloses a buoyancy demonstrating device, including demonstration container, water container, base and raceway, demonstration container and water container set up on the base, just demonstrate the container and are linked together through the raceway with water container, are provided with the switch on the raceway. The upper end of demonstration container is provided with the upper cover, and the lower extreme of upper cover is provided with the hanging stick, is provided with the fixed pulley on the hanging stick, sets up the suspension wire on the fixed pulley, and the both ends of suspension wire are connected with combination heavy object and single heavy object. The utility model discloses a buoyancy demonstrating device does the contrast through set up two sets of heavy objects in the enclosure space, can demonstrate two sets of contrasts according to from balanced unbalance gradually to the water intrusion slowly in, reaches the complete process of new balance afterwards, and the demonstration process is clear, comprehensive, and the demonstration effect is vivid, helps improving give lessons efficiency and quality, the deep understanding of the help student content of giving lessons.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of buoyancy demonstrating device.
Background technology
In curricula, often can use various teaching aid, as the compasses on mathematics class, the oxygen preparation facilities etc. on Chemistry Courses, the application of teaching aid contributes to student and understands course content more deeply, vivo.In physics subject, mechanical knowledge is the most basic is also one of most important content, buoyancy is again more abstract in mechanics and indigestible part, student can be helped effectively to understand mechanics content by suitable teaching demonstration instrument, teaching aid about mechanics especially buoyancy in current junior-senior high school course is also less, this brings certain inconvenience to teachers' instruction, also have impact on efficiency of teaching and quality to a certain extent.
Summary of the invention
The purpose of this utility model is just to provide a kind of buoyancy demonstrating device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises Presentation Container, tank, base and water-supply-pipe, and described Presentation Container and tank are arranged on base, and Presentation Container is connected by water-supply-pipe with tank, and described water-supply-pipe is provided with switch.
The upper end of described Presentation Container is provided with upper cover, on cover and be provided with air vent, the lower end of described upper cover is provided with hanging stick, hanging stick is provided with fixed pulley, fixed pulley arranges suspension wire, the two ends of suspension wire are connected with combination weight and single weight, and described combination weight is four sizes solid little iron ball all identical with quality of series connection, and described single weight is a single solid skull cracker.
Preferably, the volume sum of four of described combination weight solid little iron balls is equal with the volume of the solid skull cracker of single weight.
Preferably, the quality sum of four of described combination weight solid little iron balls is equal with the quality of the solid skull cracker of single weight.
Preferably, described Presentation Container and tank are all cylindrical transparent glass infusers.
Preferably, the volume of described tank is the twice of the volume of Presentation Container.
The beneficial effects of the utility model are:
The utility model is a kind of buoyancy demonstrating device, compared with prior art, buoyancy demonstrating device of the present utility model compares by arranging two groups of weights within the enclosed space, can demonstrate two groups contrast with reference to from equilibrate to slowly be immersed in the water unbalance gradually, finally reach the complete procedure of new balance again, presentation process cleaning, comprehensively, demonstrating effect is vivid, contribute to raising to give lessons effect and quality, help student's profound understanding lecture contents, structure is simple, easy to use, has the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of buoyancy demonstrating device described in the utility model.
In figure: 1-Presentation Container, 2-tank, 3-base, 4-water-supply-pipe, 11-upper cover, 12-air vent, 13-hanging stick, 14-fixed pulley, 15-suspension wire, 16-combine weight, the single weight of 17-, 41-switch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises Presentation Container 1, tank 2, base 3 and water-supply-pipe 4, Presentation Container 1 and tank 2 arrange on the base 3, Presentation Container 1 and tank 2 are all cylindrical transparent glass infusers, and the volume of tank 2 is the twice of the volume of Presentation Container 1, Presentation Container 1 is connected by water-supply-pipe 4 with tank 2, and water-supply-pipe 4 is provided with switch 41.The upper end of Presentation Container 1 is provided with upper cover 11, upper cover 11 is provided with air vent 12, air vent 12 can balance the pressure in Presentation Container 1, the lower end of upper cover 11 is provided with hanging stick 13, hanging stick 13 is provided with fixed pulley 14, fixed pulley 14 arranges suspension wire 15, the two ends of suspension wire 15 are connected with combination weight 16 and single weight 17, combination weight 16 is four sizes solid little iron ball all identical with quality of series connection, single weight 17 is a single solid skull cracker, volume and the quality sum of four solid little iron balls of combination weight 16 are equal with quality with the volume of the solid skull cracker of single weight 17 respectively.。
Combination weight 16 in Presentation Container 1 and single weight 17 due to quality equal, so initial time combination weight 16 and single weight 17 balance, the two is adjusted to bottom end in the same horizontal line, open switch 41, the water in tank 2 is made to flow in Presentation Container 1, water in Presentation Container 1 is dipped combination weight 16 and single weight 17 gradually, combination weight 16 and the single weight 17 unbalance process finally reaching new balance again gradually then can be demonstrated in process, show the action effect of buoyancy in process then vividly, contribute to the study enjoyment increasing student, improve learning quality.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
