Description
[technical field]
The utility model relates to a kind of limnograph.
[background technology]
The water level gauge that is adopted in the hydrographic survey at present mainly contains water gauge, contact level measurement device, float type level meter, ultrasonic type water level gauge and pressure type water level gauge.Though wherein water gauge is simple and easy to usefulness, owing to be the artificial observation waterlevel data, be easy to generate deviation and automatization level is low.The contact level measurement device comprises two types of needle water level gauge, hanging type water level gauges, their measuring accuracy is higher, but the range of stage that needle water level gauge is surveyed is little, and the hanging type water level gauge need have stilling well, the installation cost height, and all inapplicable in ice period.Though the float type level meter precision is very high, need be installed in the well house, some place shaft building difficulty, usable range is restricted.And the ultrasonic type water level gauge is subjected to the influence of weather and water surface wave easily, causes than mistake.The pressure type water level gauge of widespread use does not now need to build well house, easy for installation, be specially adapted to build well logging or the inconvenient place of shaft building, and it is cheap, but because traditional pressure type water level gauge hypothesis water body density constant, and therefore actual water body density can not reflect the influence that measurement brings to water level of water body variable density because of the influence of factors such as salineness, silt content, makes measured value not accurate enough.
[utility model content]
Goal of the invention
The purpose of this utility model is to overcome above-mentioned prior art shortcoming, provides a kind of and installs and uses simply, and is cheap, measures limnograph accurately.Adopt the utility model to measure water level and can revise the influence that the water body variable density brings for the water level measured value, and the big precision height of measurement range, not influenced by weather, water quality, silt, ice slush, floating thing etc., be applicable to the level measuring of water body Anywhere.The utility model is installed on the bottom, riverbed, does not influence the river course, can take precautions against artificial destruction and theft simultaneously.
Technical scheme
To achieve these goals, the utility model is realized in the following ways.This limnograph is made up of pressure transducer 6, water level display 9, cable 8, cable 5, electronics tautness meter 4, pulling force rope 3, keg float 1, protection steel pipe 7 and permeable protection bucket 2.Water level display 9 is connected with pressure transducer 6 by cable 8, is connected with electronics tautness meter 4 by cable 5 simultaneously, and the other end of electronics tautness meter 4 is connected with keg float 1 by pulling force rope 3.
The principle that the utility model is measured water level is as follows:
Actual water level: H=h+h ' (1)
Wherein: h=F
Press/ ρ g (2)
Hence one can see that, actual water level H=F
Press/ ρ g+h ' (3)
In the formula: the H----actual water level
The h---measuring point is to water surface distance
H '--the actual elevation of-measuring point
F
Press---measuring point pressure
The ρ---water body density of surveying
G----acceleration of gravity
From (3) formula as can be known, actual water level is by measuring point pressure and the decision of water body density, therefore as long as collect measuring point pressure and water body density can calculate actual water level. measuring point pressure can directly be measured by pressure transducer 6. and the measuring principle of density is as follows, according to Archimedes principle, object suffered buoyancy in liquid equals the weight of the liquid of the same volume that it arranges.Suppose to have in the water body ball float that links to each other with tautness meter, this ball float stressing conditions is as follows:
F+G=F
Floating(4)
F
Floating=ρ gv (5)
Hence one can see that, the water body density p=(F+G)/gv (6)
In the formula: the suffered pulling force of F---ball float
G---ball float gravity
F
Floating--the suffered buoyancy of-ball float
ρ----the water body density of surveying
V----ball float volume
G----acceleration of gravity
By (6) formula as can be known,, can calculate water body density, determine that according to (3) formula water body density and measuring point pressure can calculate actual water level as long as measure the suffered pulling force of ball float.
The utility model promptly is to utilize above-mentioned principle manufacturing, and this limnograph is made up of pressure transducer 6, water level display 9, cable 8, cable 5, keg float 1, pulling force rope 3, electronics tautness meter 4, protection tube 7 and permeable protection bucket 2.Electronics tautness meter 4 links to each other with water level display 9 by cable 5.The other end of electronics tautness meter 4 is connected with keg float 1 by a high tenacity pulling force rope 3.Keg float 1 can be an arbitrary shape, as long as it can accurately measure volume.Can be covered with a permeable protection tube 2 outside keg float 1 and electronics tautness meter 4, protection tube 2 can be to have a plurality of permeable holes on a cylinder; Also can adopt silk screen to surround cartridge type.Its role is to prevent owing to liquid flow drives the keg float 1 caused error that swings.
Simultaneously a pressure transducer 6 is linked to each other with water level display 9 by cable 8; pressure transducer 6 and stube cable all protect with protection tube 7; protection tube 7 upper edge axis directions are (2 centimetres at for example every interval) perforate uniformly-spaced, and whole protecting pipe 7 all wraps up with nonwoven fabrics.The size in hole and shape can be determined according to actual conditions, for example can be the plum blossom holes of 6 millimeters of diameters, if can guarantee pressure transducer 6 good saturating pressure and prevent the sensitivity that silt alluvial influence is measured.Protection tube 7 one ends are connected with permeable protection tube 2, and an end extends to outside the water body.
In use, can by any known way for example the mode of underwater pile driving whole limnograph is fixed in the water body.When electronics tautness meter 4 and keg float 1 all submerge in the water body, can measure the suffered tensile force f of keg float 1 by electronics tautness meter 4, electronics tautness meter 4 is linked to each other with water level display 9 by cable 5, just electronics tautness meter 4 data of surveying can be sent in the water level display 9, obtain the water body density p by software processes.Meanwhile pressure transducer 6 is surveyed data with institute and is sent to water level display 9 by cable 8, thereby obtains measuring point pressure F
PressWater level display 9 just can be measured the actual water level under the corresponding water body density, and show by software data processing.
Beneficial effect
The utility model measurement range is big and measuring accuracy is high.Can accurately measure the water body water level that contains silt and other complicated ingredients, prevent the level measuring deviation that causes because of factor differences such as salineness, silt contents.It is simple and reliable also to have measuring method simultaneously, low production cost, and the easy advantage of installation and maintenance, and measure and not influenced by weather, water quality, silt, ice slush, floating thing etc., be applicable to the level measuring of water body Anywhere.The utility model is installed on the bottom, riverbed, does not influence the river course, can take precautions against artificial destruction and theft simultaneously.
