Abstract
The invention provides an uplift pressure measuring device of a hydraulic power plant basis gallery. The uplift pressure measuring device of the hydraulic power plant basis gallery comprises a vertical pipe arranged on a horizontal pipe and perpendicular to the horizontal pipe. An uplift pressure meter is arranged on the vertical pipe, and a monitoring pipe parallel to the vertical pipe is arranged on the horizontal pipe. The monitoring pipe is communicated with the horizontal pipe and the vertical pipe, and a bolt sealing cover is arranged on the monitoring pipe. According to the requirements of the Concrete Dam Safety Monitoring Technology Specification (DL/T5178-2003), manual comparison can be performed in uplift pressure measurement, namely an automatic measuring sensor is installed in uplift pressure measurement at the same time, one pipe and one meter are used, namely a pressure gauge and the monitoring pipe need to be arranged on uplift pressure measuring points to achieve comparison of manual observation and automatic observation, and therefore the correctness of an uplift pressure observation structure is ensured.
Description
Technical field
The present invention relates to a kind of hydroelectric power plant basic gallery uplift measurement mechanism, belong to hydroelectric power plant's uplift fields of measurement.
Background technology
Current most of hydroelectric power plant adopts sensor to realize automatic measurement to uplift pressure, but due to moist in gallery, work under bad environment, is easy to cause sensor measurement to cause and fluctuates widely, and the data precision is lower.
In each hydroelectric power plant basic gallery, the installation of uplift pressure table meter is carried out according to Fig. 1 pattern substantially at present.But due to uplift pressure water level often in change among, when uplift pressure head is greater than uplift pressure Installation Elevation, uplift pressure table can be measured uplift pressure head, survey crew is reading directly.But when uplift pressure head is during lower than uplift pressure table Installation Elevation,, when uplift pressure shown in figure is measured blind area H, uplift pressure table can not show reading, but now uplift pressure still exists.It is to be tensimeter to be unloaded down in extending into steel pipe with steel ruler to measure water level substantially that the current observation personnel of each factory run into this situation in observation, calculates uplift pressure water level, uplift pressure table is installed afterwards again.But because observation is carried out for a long time, dismounting repeatedly, is easy to cause uplift pressure table to damage.
Summary of the invention
Goal of the invention: the invention provides a kind of hydroelectric power plant basic gallery uplift measurement mechanism, its objective is complex operation that solution repeatedly dismantled uplift pressure table in the past and cause, measure the inaccurate and flimsy problem of uplift pressure table.
technical scheme: the present invention is achieved through the following technical solutions:
A kind of hydroelectric power plant basic gallery uplift measurement mechanism, comprise and be arranged on standpipe vertical with transverse tube on transverse tube, on standpipe, be provided with uplift table, it is characterized in that: on transverse tube, be provided with the monitoring pipe parallel with standpipe (4), monitoring pipe and transverse tube and standpipe UNICOM are provided with bolt seal lid in monitoring pipe.
advantage and effect:
The invention provides a kind of hydroelectric power plant basic gallery uplift measurement mechanism, comprise and be arranged on standpipe vertical with transverse tube on transverse tube, on standpipe, be provided with uplift table, on transverse tube, be provided with the monitoring pipe parallel with standpipe, monitoring pipe and transverse tube and standpipe UNICOM are provided with bolt seal lid in monitoring pipe.The present invention is according to < < concrete dam safety monitoring technology standard > > (DL/T5178-2003) requirement, uplift pressure is measured and should be able to be carried out manpower comparing pair, be that uplift pressure is measured the sensor while of automatically measuring installing, use pipe one table, be that uplift pressure measuring point answers setting pressure table and monitoring pipe to realize manually and automatic observation is compared, correct to guarantee uplift pressure observation structure.
accompanying drawing explanation:
Fig. 1 is background technology accompanying drawing of the present invention;
Fig. 2 is structural representation of the present invention.
embodiment:below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 2, the invention provides a kind of hydroelectric power plant basic gallery uplift measurement mechanism, comprise and be arranged on standpipe vertical with transverse tube 1 on transverse tube 12, on standpipe, be provided with uplift table 3, on transverse tube 1, be provided with the monitoring pipe parallel with standpipe 24, monitoring pipe 4 and transverse tube 1 and standpipe 2 UNICOMs are provided with bolt seal lid 5 in monitoring pipe 4.In figure, 6 is vent valve, and 7 is surface level, and 8 is Uplift Pressure Sensor, and 9 is sensor cable.
According to Fig. 2, the pipeline of measuring uplift pressure is transformed, a straight tube is installed on the transverse tube 1 of uplift pressure pipeline, i.e. monitoring pipe 4, tube head adopts bolt seal lid 5 to seal.When uplift pressure table head is when measuring blind area H, with spanner, turn on bolt seal lid 5, can realize uplift pressure blind area H is measured.After adopting this kind of method, can avoid repeatedly dismantling uplift pressure table, cause uplift pressure accuracy to decline so that the damage of uplift pressure table.
