Technical field
The utility model relates to hydrographic water resource, agricultural, environmental area, particularly measures a kind of simple instrument of soil water potential.
Background technology
Electrical measurement soil depressimeter is applicable to the measurement of department's soil water potentials such as hydrographic water resource, agricultural, environment, both at home and abroad in prior art, for measuring the instrument of soil water potential, how by parts such as pot clay end, gas bottle, water-supply-pipe and indicators, to be formed, pot clay end has many small holes, when insertion unsaturated soil is full of water, in hole, moisture film is connected with the water of soil mesoporosity, make the water generates negative pressure in pot clay end, this negative pressure passes to indicator by transmission water pipe, and general indicator adopts mercury manometr or vacuum gauge pressure meter reading.The soil depressimeter gas bottle using is at present little, is generally 30ml, needs frequent moisturizing, adopts mercury manometr and vacuum gauge pressure meter to need artificial reading, manual record, and reading exists error, very time-consuming taking a lot of work.
Utility model content
For the defect of prior art, the utility model proposes a kind of new electrical measurement depressimeter.
Electrical measurement depressimeter of the present utility model is achieved in that
A kind of electrical measurement soil depressimeter that the utility model provides, it comprises pot clay end 5, gas bottle 2 and pressure acquisition device, on described pot clay end 5, has micropore, it is characterized in that:
The aperture of described micropore is 0.06-0.1 μ m;
Described pressure acquisition device comprises interconnected pressure transducer 3 and data acquisition unit 8, and described gas bottle 2 tops arrange bottle cap 1, and bottom is connected with described pressure transducer 3, described pressure transducer 3 Bonding pressure conducting tubes 4;
The described pressure transmission pipe 4 of the interior insertion of described pot clay end 5 and water inlet pipe 6, described pot clay end 5 has two holes conventionally, and hole Bonding pressure conducting tube 4, one holes connect water inlet pipe 6, and the entrance of described water inlet pipe 6 arranges plug 7.
The vial that described gas bottle 2 is 300mL.
Described bottle cap 1, gas bottle 2, pressure transmission pipe 4, pot clay end 5, water inlet pipe 6, plug 7 form measures assembly, described data acquisition unit 8 connects the data of two above pressure transducers 3 all pressure transducers 3 that record connects simultaneously simultaneously, and every pressure transducer 3 is connected with one group of measurement assembly.
Electrical measurement soil depressimeter of the present utility model, as a kind of simple and easy electrical measurement soil depressimeter, the method for measurement soil water potential is performed such:
(1) during depressimeter pot clay end 5 is placed into the soil, each pressure transducer 3 is received on same data acquisition unit 8, switched on power.
(2) the measurement assembly being formed by bottle cap 1, gas bottle 2, pressure transmission pipe 4, pot clay end 5, water inlet pipe 6, plug 7 for each group, open the bottle cap 1 of gas bottle 2, transfer to plug 7, with syringe, to 6 li of water inlet pipes, inject air free water, along with the injection of water, air free water is by pot clay end 5 and pressure transmission pipe 4, through pressure transducer 3, enter into gas bottle 2, until the water in gas bottle 2 is all filled with, pull up syringe and block plug 7, tighten bottle cap 1.
(3) water in gas bottle 2 not sometimes, carries out moisturizing, because the volumetric ratio of gas bottle 2 of the present utility model is larger, the in the situation that of extreme drought, needs to mend for 10 days a water.
(4) data acquisition unit 8 records a secondary data every half an hour, within one month, downloads data.
The utility model adopts pressure sensor and data acquisition unit record negative pressure data automatically, can use the gas bottle that volume is larger, such as 300mL.Because the volumetric ratio of gas bottle is larger, the in the situation that of extreme drought, need within 10 days, mend a water, reduce the number of times of moisturizing, and do not adopted the method for current normally used artificial observation and record data, become automatic record data, time saving and energy saving.
