Abstract
The utility model provides an uplift pressure measuring device for a base gallery of a hydraulic power plant. The uplift pressure measuring device for the base gallery of the hydraulic power plant comprises a vertical tube which is arranged on a transverse tube and is perpendicular to the transverse tube. An uplift pressure meter is arranged on the vertical tube. A monitoring tube parallel to the vertical tube is arranged on the transverse tube. The monitoring tube is communicated with the transverse tube and the vertical tube. The monitoring tube is provided with a bolt sealing cover. According to the requirements of "concrete dam safety monitoring technology specification" (DL/T5178-2003), manual comparison is available for the uplift pressure measurement, that is to say, one tube and one meter are used while a sensor for automatic measurement is installed for the uplift pressure measurement, and that is to say, a pressure meter and the monitoring tube should be installed on a uplift pressure measuring point to realize comparison between manual measurement and automatic measurement, so that the accuracy of the uplift pressure measuring device is ensured.
Description
Technical field
The utility model relates to a kind of hydroelectric power plant basic gallery uplift measurement mechanism, belongs 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, in the time that 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,, in the time that 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
Utility model object: the utility model 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, measures the inaccurate and flimsy problem of uplift pressure table.
technical scheme: the utility model 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 utility model 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 utility model is according to " concrete dam safety monitoring technology specification " (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 ensure uplift pressure observation structure.
brief description of the drawings:
Fig. 1 is the utility model background technology accompanying drawing;
Fig. 2 is structural representation of the present utility model.
embodiment:below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 2, the utility model 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 in the time measuring blind area H, turn on bolt seal lid 5 with spanner, 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.
