Abstract
The utility model belongs to the technical field of underground well associated equipment, and discloses a water level observation device for an underground well. A geothermal well pumping system which belongs to the field of ground source heat pump is described by a drawing; an observation pipe is arranged in a water pumping well; the observation pipe is arranged at one side of the water pumping well; water penetration holes are arranged at the middle part and the lower part of the observation pipe; and a floating laser reflection device is placed on the water surface of an observation well. As water in the observation well is communicated with the water in the water pumping well through the water penetration holes, the water in the observation pipe is slightly influenced by a water pump, therefore the internal water surface of the observation pipe is in a relatively static state; a distance between the laser reflection device floating on the water surface inside the observation well and the well mouth is measured by a laser rangefinder, so that the water level height inside the observation pipe can be calculated, that is to say, the water level height of a well can be known; the test data are high in precision, accurate, reliable, and good in repeatability; moreover, an observation pipe detection device has the characteristics of simple and stable structure, long service life and capability of largely reducing cost for digging a well.
Description
Technical field
The utility model belongs to well water corollary equipment technical field, relates in particular to a kind of missile silo water-level observation device.
Background technology
[0002] the well water water level being observed, can directly be reflected a phreatic dynamic change in area, is the prerequisite of rational exploitation and utilization groundwater resources.Because the temperature of underground well water is higher, and suction pump work, make missile silo hydrodynamic(al) attitude flow, in pumped well, produce water vapour near the water surface simultaneously, cause than large deviation so when carrying out level measuring, receive the influence of steam and ripples.And adopt other pressure types to measure water level, and also receive the suction pump electromagnetic interference and error is bigger, cause accurately measuring.Patent CN200720101893.4 " geothermal well water-level observation device " provides a kind of other indirect measurement system of surveying water level in the pipe of measuring; Because drilling well generally all is to bore the circle well, in order to arrange the side pipe, will bore bigger well; And the aperture of drilling well is big more; Pore-forming is more difficult, and the moment of equipment needed thereby and consumed power are all big more, must increase considerably drilling cost.
Summary of the invention
The problem that the utility model will solve just provides a kind of missile silo water-level observation device that can observe at any time.For addressing the above problem, the technical scheme that the utility model adopts is: in the well water pipe, arrange a sighting tube fixed level, use the laser testing appearance to measure the distance of the water surface of well water to well head then; Reach the purpose of measuring groundwater level,, greatly reduce the cost of drilling well owing to need not bore very big well; Use laser range finder to measure the height of missile silo water level; Be not only simple and conveniently, and precision is very high, and is very valuable.
The missile silo water-level observation device that the utility model provides need not bore very big pumped well, directly puts a sighting tube in the inside of pumped well, and sighting tube is positioned at a side of pumped well, avoids suction pump as far as possible.There is the infiltration hole middle and lower part of sighting tube, also can on pipeline, not arrange the hole of seeping water, and directly does the infiltration hole by the bottom mouth of pipe of sighting tube and uses, and interior water of pipe and well water are communicated with.The sighting tube at infiltration position, hole can cover filtration beds, also can not cover filtration beds.Be placed with a floating laser reflection unit on the water surface in observation well.Owing to the interior water of observation well is to be communicated with through the water in infiltration hole and the pumped well, according to law of connected vessels, water level is identical with the interior height of water level of well casing in the sighting tube, records the interior height of water level of sighting tube and promptly knows height of water level in the well casing.Underground water does not receive the influence of suction pump in the sighting tube; Its internal water is in a kind of relative static conditions; Therefore can not produce water vapour near its water surface; Also do not have other interference, laser range finder easy to use is directly measured laser beam emitting device floating on the interior water surface of observation well and the distance between the well head.After observation finishes, sighting tube is covered, can prevent that foreign matter from getting in the sighting tube and pollute the laser reflection unit even stop up sighting tube, be convenient to carry out observe next time that perhaps putting into measuring apparatus carries out long-term remote observation.The sighting tube lid is arranged and do not have the sighting tube lid and all be included in the scope.When water table ratio is higher, have or not the laser reflection unit not influence the accuracy of measurement on the water surface, therefore, there are laser reflection unit and no laser reflection unit all to be included in the scope in the observation tube on the water surface.
Select suitable laser range finder and laser reflection unit for use, can make data testing accuracy high, accurately and reliably, good reproducibility, whole groundwater table testing arrangement is simple in structure, stable, long service life.
Description of drawings
Accompanying drawing is the principle schematic of the utility model missile silo water-level observation device, size not drawn on scale among the figure.
In the sketch map, the 1st, drinking-water pipe, the 2nd, well lid, the 3rd, observation tube lid, the 4th, all ground of well, the 5th, water surface laser reflection unit in the observation tube, the 6th, pumped well, the 7th, observation tube, the 8th, suction pump, the 9th, infiltration hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the structure and the use principle of the utility model missile silo water-level observation device are done further explain.
As shown in the figure, comprise three parts such as pumped well, water plug and the utility model missile silo water-level observation device: 2 well lids wherein, 4 wells week ground, 6 pumped wells constitute pumped well; 1 drinking-water pipe, 8 suction pumps constitute water plug, and water surface laser reflection unit, 9 infiltration holes constitute missile silo water-level observation device in 7 observation tubes, 3 observation tubes lid, 5 observation tubes.
When observing, the observation personnel are placed on 3 sighting tubes lid position with laser range finder, point to the laser reflection unit on 5 waters surface in 7 sighting tubes; Record the interior height of water level of 7 sighting tubes and promptly know height of water level in 6 pumped wells; Can realize fast accurate water-level observation, after observation finishes, sighting tube covered; Can prevent foreign matter from getting in the sighting tube and pollute the laser reflection unit even stop up sighting tube that perhaps putting into measuring apparatus carries out long-term remote observation to be convenient to carry out observation next time.
