In the process of measurement of Grounding Resistance, several suitable stubborn problems occur at ordinary times, directly reduced work efficiency: the in use non-integral body of existing measurement instrument device, this makes often forgets Work tool easily in surveying work; Need during existing measurement instrument operation that frequent carrying out put by hand, take-up work, and electric wire takes place in manual retractable cable process easily twine, directly cause operation length consuming time, speed slow; Electric wire is connected with instrument and can't fixes, and takes out continually, inserts and cause the junction loose contact, influences accuracy of measurement.

The utility model content

The technical matters that the utility model will solve is that the process work efficiency of measurement of Grounding Resistance descends, thereby integral type ground connection megger is provided.

In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: integral type ground connection megger; Comprise that first measures with line, second and measure with line, the 3rd measurement with line, earthmeter instrument; Comprise that also fixing first measures the sectional shelf-unit of measuring with line, earthmeter instrument with line, the 3rd with line, second measurement, said sectional shelf-unit is provided with is convenient to the crank handle device that first measurement is measured with the line manual withdrawal with line, the 3rd with line, second measurement.

Preferably, said crank handle device is a coupling shaft, regains through coupling shaft, and is simple and safe, simple to operate, easy for installation.

Preferably, said coupling shaft is provided with first drum, the 3rd drum, and said the 3rd drum is fixedly connected with coupling shaft, through fixing the 3rd drum of coupling shaft, and convenient first drum, the take-up simultaneously of the 3rd drum, simple and practical.

Preferably, said the 3rd drum is fixedly connected with coupling shaft through pin, also can be through other connected modes of being convenient to be fixedly connected, and pin connects simple and practical, safe and reliable, changes easily.

Preferably, be respectively equipped with connector on said first drum, the 3rd drum, said connector comprises rotatable catch, fixing catch, through the connector axle that is rotationally connected, is convenient to first drum, the take-up simultaneously of the 3rd drum, and is convenient and simple.

Preferably, said rotatable catch, fixedly catch be L shaped, L shaped be convenient to processing, performance is better, and is easy for installation.

Preferably, also comprise second drum, said second drum is provided with auto take-up, and said auto take-up can be torsion spring, can realize automatic take-up.

Preferably, also comprise the casing of placing sectional shelf-unit, the setting of casing is easy to carry, and is safe and reliable.

In sum, the advantage of the utility model: the crank handle device through being arranged on the sectional shelf-unit measures each with the line withdrawal, and it is convenient that the electric wire that makes can become in the retractable cable process, is difficult for twining; Instrument is wanted globality, is convenient for carrying; Do not change original surveying instrument connection principle, reduce the plug of connecting line, improved work efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:
