a＝h
∴X＝H+h……(1)
If the water storage cup internal diameter is D, the sighting tube internal diameter is d, and sighting tube is when the A of position, and liquid-column height is h
aKeep water storage cup position and highly constant, when sighting tube was placed position B, the liquid-column height in the sighting tube was 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 can sighting tube fluid column when the B of position rise? this is because position B is lower than position A, water in the water storage cup is under the water column pressure effect, flow to sighting tube, liquid level in the water storage cup H that also thereupon descended, 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

Therefore, the physical length of sighting tube scale section is littler than the value that indicates, and the value that is sign is divided by (1+d
2/ D
2).Range as 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, one end is very thin pipe, water is subjected to the wall tension effect that wall attachment effect is arranged in pipe, be the water segment distance that in pipe, will rise 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 viscous effect again, impels the water level in the sighting tube fluctuated, has influenced the accuracy of instrument.How just can make the interior water level of interior water level of sighting tube and water storage cup become level? we have taked to eliminate the way of tube wall surface tension force, it no longer is middle recessed making the water surface in the sighting tube, Long Qi crescent all around, but one as the metal finger straight line, and this sampling instrument is just accurate, accurate.
Water storage cup internal diameter 100mm of the present invention, sighting tube internal diameter 10mm.There is a bit of tubule the sighting tube lower end, on the length of pipe shaft 396.04mm, evenly scribes 400 lattice, and every case marker is shown 1mm.What indicate on the sighting tube is digital up-small and down-big.Fluid column rises its value from large to small, and institute's location is put lower; Fluid column its value that descends is changed from small to big, and institute's location is put higher, 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 operating radius, easy to use.The pipe plug is pegged graft easily, and the time spent does not pull out, and puts clean water, i.e. regracting water storage cup, and sighting tube is folded communicating pipe, puts the instrumentation package box into, is easy to carry.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 illustrating has bubble in the instrument.
The present invention is simple and practical, need not adjust level, and check is proofreaied and correct easily, and error is little, has opened up a new field of measuring technique, for the process control and the engineering product quality of construction quality provides safeguard.The present invention is easy to use, need not professional survey crew, construction workman oneself will use, and can preset earlier, the limit construction, the limit monitoring, oneself check construction quality, increases the new heart 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 meet the requirement of design grade, can guarantee never to produce down flashing, 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, the effect height, 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.
