AI Technical Summary

Problems solved by technology

The main reason is that the scenes in the buoyancy questions are relatively abstract, which is not convenient for students to construct
The measurement of buoyancy in general experiments is completed in at least 2 steps, which is not convenient for students to think about the equivalent relationship of buoyancy
The existing instruments in the laboratory cannot comprehensively and quantitatively measure the relationship between buoyancy, tension, and gravity. The patented technology mostly uses spring tension gauges, electronic scales or digital tension gauges on the market. There is no numerical display screen or the screen is small and the brightness is not enough. Ordinary LCD The screen cannot allow the whole class to see the experimental results
The existing technical solution does not have the function of simultaneously measuring tension and compression and displaying the calculation results

Embodiment Construction

[0015] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if an implement in a drawing is turned upside down, an implement described as "above" or "above" other implements or formations would then be oriented "below" or "over" the other implements or formations. under other devices or structures". Thus, the exemplary term "above" can encompass both an orientation of "above" and "beneath". The device may be oriented in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly...

Abstract

The invention relates to the technical field of experimental instruments and particularly relates to a buoyancy comprehensive experiment instrument. The instrument comprises a support cross beam, twosupport stand columns, two inverted-T-shaped support bases, a displacement ruler installation base, a displacement ruler locking jackscrew, a digital display displacement ruler, a tension sensor, a hook, a displacement display screen, a tension display screen, a pressure gauge base, a pressure sensor, a pressure gauge tray, a pressure display screen, a calculation result display screen, an electric control box, an overflow cup and a fixed pulley. The instrument has comprehensive functions, and can solve most problems of buoyancy and density content through experiments.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a buoyancy comprehensive experimental instrument. Background technique [0002] Buoyancy is a very versatile physical quantity, and we can solve many problems through buoyancy. For example, to solve the liquid density ρ 液 , object density ρ 物 , the object volume V 物 , displacement m 排 Wait. It can be said that buoyancy is the comprehensive application of the junior high school mechanics part, and it is the central link of many knowledge. The knowledge points and exercises related to buoyancy are relatively comprehensive, and students feel that it is more difficult. In recent years, according to the requirements of the curriculum standard, the difficulty of buoyancy has been gradually reduced, but most third-year junior high school students still talk about "floating". The main reason is that the scenes in the buoyancy questions are relatively abstract, whi...
