The utility model obtains the vadose flow speed through determining the number of the rotating ring of the impeller in unit time, compared with the traditional flow speed determining instrument, the determining instrument has small volume, simple structure and convenient operation and management, and a button cell supplies energy source for the collection and storage of the data.
Description
Technical field
The utility model relates to a kind of and the supporting flow measuring instrument of mountain region small watershed runoff collection system, is mainly used in the experimental monitoring of small watershed weathered rock fracture seepage, belongs to the small hydraulic project equipment technical field of agricultural water conservation retaining.
Background technology
Crevice water plays a part and can not replace the mountain area The development in society and economy as the mountain area precious water resource; Simultaneously, crevice water occupies critical positions as the important component part of small watershed water cycle in the isorrheic evaluation of small watershed; Traditional flow velocity instrument is mainly used in pressure and bigger pipeline and open channel (river) system of flow velocity, measures the flow velocity in a certain moment or the mean flow rate in a period of time, but difference change flow velocity constantly can not be automatically recorded; Generally acknowledge at present rotary propeller type and the turbine type current meter that precision is higher, range of application is wider, its measurement result is when the flow velocity of fluid to be measured is big, and precision is all right, but is difficult to minimum velocity and small flow velocity less than 1.0m/min are accurately measured.This has brought great difficulty for the mensuration of rock cranny seepage flow; The volume of various current meters that is applied to the open channel system in addition at present is all generally bigger than normal, also causes in the mensuration that is difficult in rock cranny seepage flow and uses.
Summary of the invention
It is wide that the purpose of this utility model provides a kind of measurement range, and the rock cranny seepage flow analyzer that particularly the lower limit flow velocity is very little is strengthened the dynamics of small watershed hydrogeology monitoring, and improved its quality.
The technical solution of the utility model is achieved in that this rock cranny seepage flow analyzer, its basic structure comprises a support, the hydrodynamic(al) impeller and the inductive switch that are provided with in the support, outside pulse producer and the registering instrument that connects, the hydrodynamic(al) impeller that it is characterized in that described analyzer is arranged on the central shaft of support, a uniform 3-5 curved surface bucket, one of them blade outer is provided with magnet, and inductive switch is arranged on the support with blade magnet rotational trajectory correspondence position.
Described rock cranny seepage flow analyzer blade be shaped as arc, the outer is provided with the counterweight suitable with magnet weight.
The inductive switch of described rock cranny seepage flow analyzer is made of the tubular type normally open contact.
The tubular type normally open contact of the inductive switch of described rock cranny seepage flow analyzer is made of two metal contact and a glass tube.
Under the support of described rock cranny seepage flow analyzer weight is set, suspension ring and lifting rope are set on the support.
The inductive switch of described rock cranny seepage flow analyzer connects pulse producer and registering instrument.
The registering instrument of described rock cranny seepage flow analyzer can be realized by computer software.
Rock cranny seepage flow analyzer of the present utility model, the relation that is directly proportional with flow rate of water flow according to the velocity of rotation of impeller, try to achieve the flow velocity of seepage flow by the analytical unit number of turns that impeller turned in the time, compare with traditional flow velocity analyzer, this analyzer volume is little, simple in structure, operational management convenient, the collection of data provides the energy with storage by a button cell, is more suitable for the collection of field test data.

Embodiment
Fig. 1, shown in Figure 2, seepage flow analyzer of the present utility model is by 6 rotations of flowing water drive impeller, inductive switch 7 sends electric signal, by counter and computer data are finished dealing with to the mensuration of rock mass seepage flow again, within the instrument connection that with lifting rope weight 8 is placed rock cranny during practical application or manually get, the crack water seepage will drive the rotation of curve of the blade when flowing, inductive switch 7 is made of two metal normally open contacts 10 and a glass tube 11, when the blade that magnet 9 is installed passes through by contact, contact will be closed under the effect of magnet, and will along with the blade that has magnet away from and disconnect immediately, to produce a pulse electrical signal in this course, this pulse electrical signal is transferred in the counter by lead, because flowing of water, and the form that the electric signal counter that pulse producer is produced adds up with numeral was together noted together with the time that signal produces.Behind the work certain hour, with the data processing in the counter, just can calculate the flow velocity of rock cranny seepage flow by computer software.
For the rotating speed that makes impeller is accurate, blade of the present utility model is designed to arc, and the end of one of them blade is provided with magnet, and the end of rest blade is provided with corresponding counterweight with magnet.
