∴ X＝H+h……(1)
If the water storage cup internal diameter is D, the sighting tube internal diameter is d, and during A, liquid-column height is h to sighting tube in the position
aKeep water storage cup position and highly constant, when placing position B to sighting tube, the liquid-column height in the sighting tube is h
bBecause position B is than the low X of position A, so h
bGreater than h
a, the value that fluid column rises is h=h
b-h
aWhy sighting tube in the position during B fluid column can rise? This is because position B is lower than position A; Water in the water storage cup has flow to sighting tube under the atmospheric pressure effect, the H that also thereupon descended of the liquid level in the water storage cup; Because water storage cup and sighting tube have been formed linker; The liquid volume that flows out in the water storage cup equals the interior liquid volume that flows into of sighting tube, promptly

Range like statoscope is 400mm, water storage cup inside diameter D=100mm, and sighting tube inner diameter d=10mm, the physical length of sighting tube high scale section must be 396.04mm.Promptly on the length of the 396.04mm of sighting tube, evenly scribe 400 lattice, every case marker is shown 1mm.
Above mathematical derivation is that the liquid level that is based upon in the container of linker two ends becomes on this principle of level; Though our statoscope also is a linker; But an end is a container, and an end is very thin pipe, and water receives the wall tension effect that wall attachment effect is arranged in tubule; Be that the water end distance that in pipe, will rise leaves more, make the interior water surface of the water surface and water storage cup in the sighting tube out-of-level.Owing to the surface tension effects of water itself, water rises in pipe or descends has viscous effect again, causes the water level in the sighting tube fluctuated, has influenced the accuracy of instrument.How just can make the water level in the sighting tube become level with the interior water level of water storage cup? We take to eliminate the way of wall tension, and making the water surface in the sighting tube no longer is recessed crescent, but one as the metal finger straight line, and accurately how this sampling instrument with regard to.
Water storage cup internal diameter 100mm of the present invention, sighting tube internal diameter 10mm evenly carves 400 lattice on the length of 396.04mm on the sighting tube, and every case marker is shown 1mm.What indicate on the sighting tube is digital up-small and down-big.Institute's location is put when hanging down, and fluid column rises its value from large to small; Institute's location is put when higher, and fluid column its value that descends is changed from small to big, and meets people's thinking habit like this.Select transparent ageing-resistant plastic hose communicating pipe for use, form by multistage, purpose be not the time spent can disassemble instrument separately, be convenient to draw in and deposit, also be in order to form the different working radius, to be convenient to measure and to use.The pipe plug is pegged graft easily, with after unplug, discharge water, i.e. regracting water storage cup, sighting tube is folded communicating pipe, puts the instrumentation package box into.To note the bubble in emptying communicating pipe during use.As being mixed with bubble, when measuring the elevation of same position, the water level in the sighting tube will come and go in communicating pipe, and explaining has bubble in the instrument.
The present invention is simple and practical, need not adjust level, and the danger is tested and proofreaied and correct easily, and error is little, has opened up an incompetent field of measuring technique of spirit-leveling instrument, for the process control and the engineering product quality inspection of construction quality provides safeguard.The present invention is easy to use, need not professional survey crew, need not full-time lineman, construction workman oneself will use, but and the limit measure, the limit construction, the limit monitoring, last own inspection construction quality increases confidence to the construction operation personnel.Before the building ground engineering construction, find out the peak on ground earlier, can save material, guarantee that levelness, gradient error comply with the national standard requirements.Utilize statoscope to make flashing, can guarantee the requirement of design grade fully, can not produce down flashing and excess surface water phenomenon again.Statoscope has been eliminated the snap the line method of continuity many decades in the construction work, and direct production technique ground on the ground is succinct, save trouble, accurately, and effect is high, and quality is good.Utilize statoscope to detect ground surface works, more reliable than visual inspection, than pouring water test science, accurately than the grade rod check.Utilize statoscope to detect camber, amount of deflection, the set-back of bridging crane main beam, than backguy method simply, conveniently, save time; Utilize statoscope to detect the level height difference of high aerial overhead crane orbit and wall mouth etc.,, stand on the ground and just can measure also without snap the line.Be used as teaching aid, can inspire student's mathematical derivation and creative thinking ability.
