Refer to Fig. 1 and Fig. 2, the Level monitor suitable for laser optical method in the present embodiment, including water level pipe
100 and reflector 200, water level pipe 100 be vertically embedded in water table measure point, be provided with the inner tubal wall of water level pipe 100 some
Guide groove 101, guide groove 101 are through to bottom from the top of water level pipe 100, and reflector 200 is floated on the water surface in water level pipe 100, instead
The size of tabula rasa 200 is adapted with water level pipe 100, i.e. the slightly smaller than size of water level pipe 100, and be provided with reflector 200 with
The adaptable some linking arms 210 of guide groove 101, the expansion termination of linking arm 210 is located in guide groove 101.
The Level monitor suitable for laser optical method in the present embodiment, has the following advantages that：Set in water level pipe 100
Reflector 200 is put, as the reflecting medium of laser surveying instrument, the water surface and water quality impact can be eliminated, improve the essence of measurement
Degree and speed；Meanwhile the linking arm 210 of reflector 200 is placed in the guide groove 101 on the inwall of water level pipe 100, reflector 200 can
Freely to be moved up and down with water level, and the mobile restricted system of horizontal direction, reflector 200 is in horizontality all the time, it is effectively anti-
Only reflector 200 in moving up and down tilt or in water-level fluctuation swing etc. situation, further improve measurement accuracy.
Water level pipe 100 sets some filter openings through the tube wall of water level pipe 100 from the side wall of the upward certain altitude in bottom
102, underground water is entered in water level pipe 100 by filter opening 102, the water level in water level pipe 100 is kept consistent with groundwater level.
Preferably, as shown in figure 3, the cross section of guide groove 101 is the circle with a breach, linking arm 210 has one
Expand termination, expand the cross section of termination also for circle, the diameter for expanding termination is slightly less than the diameter of guide groove 101 and is more than breach
The distance between, it is ensured that linking arm 210 moves up and down in guide groove 101, while is unlikely to skid off from guide groove 101 again.
More preferably, the angle α of the breach of the circular cross sections of guide groove 101 to circular circle center line connecting is less than or equal to 120 °, further, α
∈ [60 °, 90 °].
Preferably, as shown in figure 4, the cross section of guide groove 101 is the ellipse with a breach, the expansion of linking arm 210
The cross section of termination is also ellipse, and the major axis for expanding termination is slightly less than the major axis of guide groove 101 and is more than the distance between breach,
It can ensure that linking arm 210 moves up and down in guide groove 101, while be unlikely to skid off in dynamic guide groove 101 again.More preferably, lead
The angle β of the breach of the oval cross-section of groove 101 to elliptical center line is less than or equal to 135 °, further, β ∈ [60 °,
120°]。
The increase of the quantity of guide groove 101, the limitation to the displacement in the horizontal direction of reflector 200 can be increased, but can increased simultaneously anti-
The resistance that tabula rasa 200 moves in vertical direction, it is preferably that guide groove 101 is 3~5.
Rainwater flows into water level pipe 100, and the water surface in water level pipe 100 will be caused to raise, so that measurement result produces error.It is excellent
Elect as, as shown in figure 1, the upper end of water level pipe 100 is provided with rubber stopper 1, closes the mouth of pipe of water level pipe 100, prevent rainwater from flowing into
Water level pipe 100.Further, the top of water level pipe 100 is less than ground 300, and the top of water level pipe 100 is provided with cover sheet 104,
Cover sheet 104 is held in the groove on ground 300.Cover sheet 104 is set, can both protect the mouth of pipe of water level pipe 100,
Passed through again without prejudice to earth's surface.
However, in Fig. 1, after heavy showers or continuous rainfall, the hole 310 between cover sheet 104 and rubber stopper 1
In carry out level measuring, it is necessary to first remove ponding and could open rubber stopper 1 there may be ponding even on ground 300, this
Largely effect on the efficiency of water level monitoring.More preferably, as shown in figure 5, the top of water level pipe 100 is embedded with rubber tube 110, rubber tube
110 tops are higher by the top of water level pipe 100, and rubber stopper 2 111 is provided with rubber tube 110.When the ponding in hole 310 is less than rubber
During the top of sebific duct 110, rubber tube 110 is brought into close contact with water level pipe 100, can prevent ponding from entering in water level pipe 100, therefore,
It need not drain the water away, can directly open rubber stopper 2 111 and measure water level in water level pipe 100；When ponding, hole occurs in ground 300
When water level in 310 exceedes the top of rubber tube 110, rubber tube 110 can be extracted one section of height upwards, make rubber tube 110
Top is exposed the surface, and then opens rubber stopper 2 111, measures the water level in water level pipe 100, because rubber tube 110 is flexible,
During pulling up upwards, remain in that and be brought into close contact between water level pipe 100, prevent ponding from entering water level pipe therebetween
In 100.Rise for convenience and pull out rubber tube 110, handle 112 is provided with the top side wall of rubber tube 110.Rise upwards when pulling out,
