Embodiment
[0088] Such as figure 1 , figure 2 As shown, a demonstration device for visually verifying Archimedes' principle includes a frame 1 and two water tanks 2 of the same size and arranged side by side. The front ends of the water tanks 2 are provided with overflow ports 21, and also include:
[0089] Water irrigation mechanism 3, said water irrigation mechanism 3 is installed on said frame 1, and it carries out irrigation work to two described water tanks 2 respectively;
[0090] Two liquid injection weight-increasing mechanisms 4, the liquid injection weight-increasing mechanisms 4 are installed on the frame 1 in one-to-one correspondence with the water storage tank 2, and are all located above the water storage tank 2, which are used for The buoyancy member 5 for the buoyancy test performs the work of injecting liquid and increasing the weight, and the buoyancy member 5 is used for carrying out the buoyancy test in the water holding tank 2;
[0091] A driving mechanism 6, the...
Embodiment 2
[0155] Such as Figure 13 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment two and embodiment one is:
[0156] further, such as Figure 13 As shown, the two electronic scales 72 are connected by a round rod 720 , and the other end of one electronic scale 72 is fixedly connected with a rocker 722 .
[0157]It should be noted that, after the reading of the electronic scale 72 and the measuring cup 72 is completed, the rocker 722 is shaken, and the electronic scale 72 and the measuring cup 73 at the two places rotate downward at the same time, and the homogeneous solution inside the two measuring cups 73 is poured into the recovery box 74 , to facilitate the next experiment, while collecting the solution to avoid waste...

Abstract
The invention relates to physics teaching auxiliary equipment, in particular to a demonstration device for visually verifying the Archimedes principle, which comprises a rack and two water containing tanks which are consistent in size and are arranged side by side, and overflow ports are formed in the front ends of the water containing tanks. The demonstration device further comprises a water filling mechanism, wherein the water filling mechanism is mounted on the rack and used for filling water into the two water containing tanks respectively; two liquid injection weight increasing mechanisms, wherein the liquid injection weight increasing mechanisms and the water containing tanks are installed on the rack in a one-to-one correspondence mode, the liquid injection weight increasing mechanisms and the water containing tanks are both located above the water containing tanks, the liquid injection weight increasing mechanisms are used for conducting liquid injection weight increasing work on a buoyancy part used for conducting a buoyancy test, and the buoyancy part is used for conducting a buoyancy experiment in the water containing tanks; a driving mechanism mounted on one side of the rack and used for driving the water filling mechanism and the two liquid injection weight increasing mechanisms to work at the same time; and two measuring mechanisms mounted on the front sides of the water containing tanks in one-to-one correspondence with the water containing tanks.
Description
technical field [0001] The invention relates to auxiliary equipment for physics teaching, in particular to a demonstration device for visually verifying Archimedes' principle. Background technique [0002] Physics is a discipline that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles. Based on the research basis of scientific disciplines, physics teaching needs to use buoyancy demonstration devices, but most of the buoyancy demonstration devices used in physics teaching in the past are not effective, which reduces the user's experience of buoyancy demonstration devices for physics teaching, and cannot meet the needs of today's market. need. [0003] In the patent literature with the application number CN201420163779.4, a demonstration instrument for demonstrating the buoyancy...
