Abstract
The utility model discloses a balance hammer type slope measurer, which is provided with a sealed barrel. The inner top of the sealed barrel is respectively articulatedly suspended with a displacement sensor and a counterweight. The displacement sensor and the counterweight keep parallel vertical sagging all the time under the action of gravity, the lower ends of the displacement sensor and counterweight are fixedly connected into a whole by a connecting plate, and the power and the signal wire of the displacement sensor are led out from the sealed barrel by a sealed member. The utility model can automatically continuously monitor the gradient of the soil bodies or buildings and has the advantages of simple structure, convenient operation and stable operation.
Description
The utility model relates to the surveying instrument of measuring dike, dam, geotechnical slope, excavation of foundation pit wall, retaining wall isolith geotechnique journey building inclination degree in the engineering survey, is meant a kind of counterweight system tiltmeter especially.
At present, the instrument tiltmeter that is used to measure ground building inclination degree both at home and abroad generally is made up of gauge head, plate reading and deviational survey pipe, the CX-01A type tiltmeter of making as 33 research institutes of National Space Industry Corporation.The gauge head of this type of tiltmeter is a core, is the place, source of measuring-signal.A servo accelerometer is housed in the gauge head, and accelerometer has a sensitive axes.When gauge head tilted, sensitive axes also tilted, and sensitive axes and datum line are that the acceleration of gravity line just has an angle, and accelerometer just has an output.Deviational survey is run affairs and vertically is embedded in the soil earlier, if soil body occurred level displacement such as dike, dam then the deviational survey pipe will be crooked.During measurement, the tiltmeter gauge head moves in the deviational survey pipe of bending, just can measure the inclination angle at different elevations place, just can obtain the horizontal shift at different elevations place through accumulation calculating.The problem of this tiltmeter is: (a) must bury the deviational survey pipe in advance; (b) necessary manually-operated allows gauge head move in the deviational survey pipe.When the deviational survey pipe is not had (as flood) by water logging, just can not remake measurement; (c) can only measure discontinuously, therefore the process of energy measurement soil body continuous dislocation can not do real-time monitoring; (d) technology content of accelerometer is higher, and general manufacturer production difficult quality guarantee causes the precision of tiltmeter lower, and easy break-down, and serviceable life is short, will scrap in general 3 years, and use cost is higher.
The purpose of this utility model be exactly to provide a kind of can the automatic continuous monitoring soil body or the degree of tilt and simple in structure, easy to operate, the stable and reliable operation counterweight system tiltmeter of buildings.
For realizing this purpose, the counterweight system tiltmeter that the utility model is designed, has a sealing bore, a hinged respectively displacement transducer and the balance bob of being hung with of sealing tube inner tip, displacement transducer and balance bob remain parallel vertical under action of gravity sagging, the lower end of displacement transducer and balance bob is fixedly connected by a plate, and the power supply and the signal wire of displacement transducer are drawn from sealing bore by seal member.Its principle of work is such: the counterweight system tiltmeter vertically is embedded in the soil or is fixed on the buildings, when the soil body or buildings run-off the straight, and the sealing bore inclination equal angular of tiltmeter.Because displacement transducer and balance bob all are articulated on the sealing bore inner tip, and both combine as a whole the lower end, and in the action of gravity of balance bob, displacement transducer and balance bob remain vertical, and the length of balance bob can not change, and just makes displacement transducer elongate or shorten.The deflection of displacement transducer is corresponding with the angle of inclination of sealing bore, can obtain between the two linear relation by rating test.Thereby, just can know the pitch angle of the soil body or buildings by the output of displacement transducer.
Advantage of the present utility model is: displacement transducer and balance bob are installed in the sealing bore, can not be subjected to the influence of external environment conditions such as ponding, the power supply and the signal wire of displacement transducer are connected on the automatic data acquisition device, can realize uninterrupted continuously automatically monitoring, can monitor too under the floodage in flood season.Sealing bore can directly be embedded in the soil and without the deviational survey pipe, also can be installed on the deviational survey pipe, can also be bundled on the wall of any buildings such as excavation of foundation pit its simple structure, easy to install quick.Displacement transducer then is a device the most ripe in the engineering surveying instrument, and its precision and long-time stability are all guaranteed, and counterweight system tiltmeter processing based on this is simple, precision is high, long-time stability good, and cost is extremely low.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a kind of structural representation of counterweight system tiltmeter;
Fig. 2 is the measuring principle synoptic diagram of this tiltmeter.
Counterweight system tiltmeter shown in the figure comprises the sealing bore that is made of cylindrical shell 10, upper end cover 1, bottom end cover 12, is provided with O RunddichtringO 5 between upper end cover 1 and the cylindrical shell 10, is provided with O RunddichtringO 13 between bottom end cover 12 and the cylindrical shell 10, and is fastening with being threaded.In upper end cover 1 installed inside one bearing support 11 is arranged, bearing support 11 is by a hinged respectively displacement transducer 6 and the balance bob 7 of being hung with of wire rope 2, displacement transducer 6 and balance bob 7 remain parallel vertical under action of gravity downward, and both lower ends connect plectane 8 by one and are fixedly connected.Have a wire hole on upper end cover 1, this wire hole is by O RunddichtringO 3 that sets within it and holding screw 9 sealings, and the power supply of displacement transducer 6 and signal wire 4 are drawn from sealing bore by this wire hole.For the remote long term monitoring in field, comparatively stable with the frequency signal transmission, displacement transducer 6 should select to be output as the type of frequency signal.Select small-sized displacement transducer, can make the physical dimension of tiltmeter very little.
With this counterweight system tiltmeter vertically be embedded in soil in or be fixed on the buildings, when the soil body or buildings run-off the straight, the sealing bore cant angle theta angle of tiltmeter will make displacement transducer elongate or shorten Δ h distance.Power supply and signal wire by displacement transducer are transferred to data acquisition unit with signal, can calculate the pitch angle of the soil body or buildings.
