Abstract
The utility model comprises a device for detecting the levelness of an underwater temporary support block of an immersed tube tunnel. The device comprises an inclination sensor and a liquid level sensor that are arranged on the surface of the underwater support block to be detected, and are used for detecting the angle of inclination and the depth; and the signal of the angle of inclination output by the inclination sensor and the depth signal output by the liquid level sensor are output into a computer by a receiving module and a signal conversion module, and the data is stored and displayed by display software. The device not only is capable of quickly and accurately detecting whether the detected object is installed in place or not, but also is capable of recording the measurement data for adjustment.
Description
Technical field
The utility model relates to the pick-up unit of a kind of levelness and the degree of depth, in particular, relates to a kind of to the levelness of the submerged structure that can not directly contact and the pick-up unit of elevation.
Background technology
At present, traditional interim under water back-up block levelness detection is to extrapolate levelness and elevation through calculating wirerope displacement.But because the deviation that wirerope is installed causes measuring error bigger with flexible easily.
The utility model content
The utility model is to the defective that exists in the above-mentioned prior art; Provide a kind of immersed tube tunnel interim back-up block levelness detecting device under water; Can not only measure measured object quickly and accurately and whether be in place, can also measurement data record be got off simultaneously, with foundation as adjustment.
For achieving the above object, the technical scheme that the utility model adopts is following:
The interim under water back-up block levelness detecting device of a kind of immersed tube tunnel; Said device comprises inclination sensor and the liquid level sensor that is placed on back-up block to be measured surface under water, is used to detect its inclination angle and the degree of depth; The depth signal of the dip angle signal of said inclination sensor output and the output of said liquid level sensor outputs on the computing machine through receiver module and signal conversion module, and the preservation data also show through software for display.
The analog voltage signal of said inclination sensor output is after signal condition module conditioning, and the A/D through single-chip microcomputer converts needed digital signal into again, through respective algorithms, and the output dip angle signal, this signal is transferred to receiver module again.
Said signal condition module comprises reference voltage chip and deflection voltage chip; The reference voltage chip is adjusted to high-precision 5V reference voltage with the 5V input voltage; The analog voltage signal and the 5V reference voltage of inclination sensor output are nursed one's health 0～5V with the analog voltage signal of-2.5～2.5V behind the deflection voltage chip, convert needed digital signal into through single-chip microcomputer again.
The transmission of said signal is transmitted through communication cable.
The beneficial effect that the utility model technical scheme is brought:
Adopt inclination sensor and liquid level sensor as measurement module; Communication cable, signal condition module, receiver module and signal conversion module are as communication media; Computing machine is as measurement display unit, and whether the installation that can detect interim lip block meets the requirements, simultaneously through the three-dimensional picture attitude that shows interim lip block directly perceived; Native system is quick, accurate, convenient measurement, simple in structure.
Description of drawings
Below through accompanying drawing the utility model technical scheme is done and to be described in further detail:
Fig. 1 is the system chart of the utility model;
Fig. 2 is a signal condition module composition frame chart among Fig. 1.
Embodiment
In Fig. 1; The analog voltage signal of inclination sensor 1 output, convert the analog voltage signal of 0～5V into through signal condition module 3; A/D through single-chip microcomputer 4 converts digital signal into the analog voltage signal after the conversion; Pass through corresponding algorithm simultaneously, the output pitch angle passes to computing machine 7 with the depth signal of liquid level sensor 2 outputs and the dip angle signal after single-chip microcomputer 4 processing through receiver module 5 and signal conversion module 6 at last.
Signal condition module shown in Figure 2 comprises reference voltage chip 8 and deflection voltage chip 9.At first with obtaining high-precision 5V reference voltage behind the 5V input voltage process reference voltage chip 8; Its initial precision is 2.0mV; The output analog voltage signal of inclination sensor 1 and reference voltage are nursed one's health 0～5V through deflection voltage chip 9 with the analog voltage signal of-2.5～2.5V then, convert needed digital signal into through single-chip microcomputer 4 again.
