Head, the poles A probe and the poles B probe are exposed outside and distance is closer, and the poles A probe is electric with resistance measurement device by survey line with the poles B probe
Connection.When for water level monitoring, two probes completely attach to liquid in drilling well, and resistance value significant change is popped one's head in by controlling, chased after
Track fluctuation in stage process, achievees the purpose that water level monitoring.
During carrying out deep-well pumping experiment, due to borehole wall water burst, water-level probe ponding etc., it is easy to cause naked
The probe to expose outside measures an artifical water height, and dynamic water level actual value measurement difficulty is larger, and sensitivity is relatively low；And conventional water level monitor
Survey line be susceptible to damaged, deformation, service life is short；Scale observed stage is tied up outside survey line, records, is troublesome in poeration, taking simultaneously
Band places water-level instrumentation more inconvenience.
Utility model content
In view of the above technical problems, the utility model is intended to improve the anti-interference ability of water-level instrumentation, improves test essence
Degree and sensitivity；Effectively control survey line is damaged, deforms, and extends survey line service life；Improve observation, record, carrying and operation
Convenience.
For this purpose, technical solution used by the utility model is：A kind of deep-well pumping experiment water-level instrumentation, including control
Case and water-level probe, are provided with resistance measurement device and wire spool in the control cabinet, the water-level probe include probe body with
And the rubber protective layer for coating probe body completely, the poles A exploration hole is provided in the rear sidewall of water-level probe, water-level probe
Front center is provided with the poles B exploration hole, the survey line in water-level probe pass through water-level probe tail end, further around cross wire spool, finally with
Resistance measurement device is electrically connected；The poles A exploration hole is at least 25cm at a distance from the exploration hole of the poles B, and scale is carried outside the survey line
Groove carries steel wire protection line in the survey line secretly.
It is vertically arranged with partition board in the control cabinet as a preferred embodiment of the above solution, to make resistance measurement device and coiling
Disk is located in different cavitys, and water-level probe can be received into the cavity where wire spool.Advanced optimize space cloth
Office, facilitates classified finishing and storage.
Further, a diameter of 20mm of the water-level probe, length 30cm.
The utility model has the beneficial effects that：
(1) water-level probe is protected using full rubber, and the poles A exploration hole and the poles B exploration hole is respectively set, and the poles A exploration hole is just
To the poles the A probe in probe body, the poles B in the exploration hole face probe body of the poles B are popped one's head in, while the poles A exploration hole and the poles B being visited
The distance controlling of gaging hole is in 25cm or more, dual measure artifical water height caused by effectively to avoid borehole wall water burst, water-level probe ponding
It measures, improves measuring accuracy and sensitivity, strong antijamming capability；
(2) it carries steel wire protection line in survey line secretly, improves the intensity of survey line, can effectively control survey line deformation, further increase
Measurement accuracy extends the service life of survey line；
(3) survey line carries staff gauge reticle, when use need not bondage scale again, facilitate observation, record and operation；
(4) resistance measurement device and wire spool are installed in control cabinet, easy to carry, it may also be used for storage water-level probe.
