In addition, Level monitor 1 may also include a mounting ring 70 and at least one seal washer (not shown).Closure
40 upper surface periphery forms the annular installation portion 45 for matching the mounting ring 70, the seal washer pad located at closure 40 with it is interior
Between cylinder 20, installation is fastenedly connected by mounting ring 70 and coordinated seal the opening of closure 40 and inner barrel 20.At this
In embodiment, the tapped through hole 44 consistent with the screwed hole of inner barrel 20 24 is respectively equipped with annular installation portion 45 and mounting ring 70
With 74.So only need to it be can be achieved outer cylinder body 10, inner barrel 20, closure 40 and mounting ring 70 by four screws or bolt
It is fixedly installed togather.Wherein, the thickness of mounting ring 70 is identical with the depth of annular installation portion 45, so as to mounting ring 70 and sealing
Lid 40 forms a flat surface.
In addition, Level monitor 1 may also include a circuit fixes sleeve 50, circuit fixes sleeve 50 has and inner barrel
The structure of 20 Matching installations, its upper end have flange 51, and flange 51 sets the screwed hole consistent with the screwed hole 24 of inner barrel 20
54.Water level monitoring circuit 30 is arranged in circuit fixes sleeve 50, and circuit fixes sleeve 50 is arranged installed in inner barrel 20 again
It is interior and pass through.This structure is easily installed maintenance.
In addition, Level monitor 1 also includes battery 60 and spring (not shown), spring and battery are arranged at inner barrel 20
Inner bottom part and circuit fixes sleeve 50 outer bottom between, battery is fixed in inner barrel 20.Battery 60 is supervised with water level
Slowdown monitoring circuit 31 electrically connects, so as to be powered to water level monitoring unit 30.Preferably, battery 60 is that capacity is more than 13000mAh, 12V
Chargeable lithium cell.
In addition, Level monitor 1 also includes remote communication module 80, remote communication module 80 and water level sensing unit 30
Electrical connection, for being communicated with remote data center and data exchange.Remote communication module 80 is prior art, here just not
It is described further again.
In addition, Level monitor 1 also includes Intelligent water level monitoring modular, the Intelligent water level monitoring modular is embedded in water level
In the microprocessor of monitoring device 1.The Intelligent water level monitoring modular carries out data analysis to the water level continued to monitor, judges
SEA LEVEL VARIATION trend changes monitoring frequency so as to intelligence, and monitoring frequency is then reduced when water accumulation level is maintained at certain level for a long time
Rate, then increase monitoring frequency when water level rapidly goes up or declined.
Now briefly explain the installation of Level monitor and operation principle.One, which is bored, in selected mount point compares outer cylinder body
The slightly larger mounting hole of size, then toward being put into appropriate rapid-curing cutback liquid cement in mounting hole, then Level monitor is put into by hole,
Flatten to road surface, that is, complete Level monitor installation.The ground pile type Level monitor of the present invention is installed on position to be measured
Lower section, ground pile type Level monitor are at least partly installed on below ground, i.e. ground pile type Level monitor is installed on above-mentioned
After mounting hole, there is part protrusion road surface to set, referring to above-mentioned, can also all be pressed within ground until flattening to road surface.When
When needing to safeguard or when monitoring point after transformation no longer waterlogging and select move dress Level monitor when, only inner barrel need to be taken
Go out, outer cylinder body is stayed in original place.After installation is complete, Level monitor is in ultra-low power standby state, i.e., now remote
Cheng Tongxin, detection circuit, probe etc. are closed.When ponding will start contact conducting, Level monitor launches into monitoring
State.Meanwhile Intelligent water level monitoring modular carries out data analysis to the water level that continues to monitor, judge SEA LEVEL VARIATION trend so as to
Intelligence changes monitoring frequency, and when water accumulation level, being maintained at certain level then reduces monitoring frequency for a long time, when water level rapidly goes up
Or decline then increases monitoring frequency.The water level monitored can transmit to remote data center to enter to advance by remote communication module
The processing of one step.
In summary, ground pile type Level monitor provided by the invention has convenient for installation and maintenance and is not easy by temperature shadow
The advantages of ringing.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
