Connect；Detection information is transferred to server by GPRS module by second controller.
In the present invention, geothermal well is followed successively by well cementation section, filter well section and precipitation well section from top to bottom, and geothermal well is built
The geologic structure of position is divided into 5 meters of farinose argillic horizon, the argillaceous siltstoue layer of 7 meters of boulder bed and 5 meters from top to bottom,
Loosely organized due to farinose argillic horizon, and water content is few, therefore in order to ensure the stability of casing programme, and prevent cold
Water enters in geothermal well, well cementation section depth is set to 6 meters, and is entered by the way of 6 meters of long wall casings and recharge cement mortar
Row is reinforced；Water content due to boulder bed is enriched, and therefore arranges, in boulder bed, the filter well section that depth is 6 meters, long using 6 meters
Water-permeable pipe reinforce, between water-permeable pipe and well bore setting filter can by subsoil water silt intercept water-permeable pipe with
Between well bore, prevent silt from entering in geothermal well, and fill cobble between water-permeable pipe and well bore, to be further ensured that filter
The stability of well section, simultaneously because implant is identical with the main component of geology residing for filter well section, does not interfere with subsoil water
Circulation；5 meters long of precipitation well section is set in filter well section bottom, when filter hydraulic performance decline, inevitably has
Silt enters in geothermal well, now, because the density of silt is more than the density of water, therefore under gravity, silt meeting
Fall in the bottom of precipitation well section, blood circulation will not be entered by diving pumped, improve the quality at water source in geothermal well, due to
Argillaceous siltstoue is more hard, and therefore this precipitation well section is designed as open hole, and its diameter is less than well cementation section and filter well section
Diameter, can save the construction cost of geothermal well while ensureing casing programme intensity.Water temperature letter is installed on the filter
Breath harvester, the information such as the water level of main collection geothermal well, water temperature and air pressure, so this water temperature information harvester includes
Power supply, baroceptor and cooling-water temperature sensor, simultaneously need to by the information transfer of collection to server, thus this water temperature information
Harvester also includes a RF radio-frequency module and the first controller, controls baroceptor and water temperature sensing by the first controller
Device detection atmospheric pressure information and water temperature information；Cooling-water temperature sensor, using longer thermistor wire, allows it be wrapped in filter
On outer surface, accurate measurement water temperature can be accomplished；The present invention detection information is transferred to by server using GPRS module it is contemplated that
The underground mining situation of GPRS jitter, is provided with water level information harvester in geothermal well well head, and water level information is adopted
Acquisition means are provided with the 2nd RF radio-frequency module, and a RF radio-frequency module and the 2nd RF radio-frequency module wirelessly connect, and reaching data has
The purpose of effect transmission；The water temperature information of water temperature information harvester collection and atmospheric pressure information pass through a RF radio-frequency module and the
The transmission of two RF radio-frequency modules, the water level information controlling ultrasonic water level sensor detection with second controller passes through after integrating
GPRS transmission is to server.
Alternatively, in the water-level and water-temperature automatic monitoring system based on geothermal well described above, filter includes one
