The length scale is arranged on the outer diameter of the positioning telescopic rod 3, and a zero scribed line of the length scale is positioned at the position of the front end cover plate 31, so that the length of the positioning telescopic rod 3 entering the hole can be conveniently measured, and the distance between a measuring position and the hole opening can be determined.
The diameter of the first end of the telescopic rod 3 capable of being positioned is smaller than that of the second end, so that the telescopic rod 3 capable of being positioned is conveniently inserted into the hole. The positioning telescopic rod 3 is a pipe shell sleeve type.
The temperature compensation line 2 is a three-core tetrafluoro temperature compensation line 2. The thermal resistance sensor 4 is a PT1000 thermal resistance sensor 4.
In this embodiment, the adjustable length that can fix a position telescopic link 3 of portable retractable temperature measurement appearance to survey under the different lithology, the original rock temperature of the different degree of depth of drilling or the temperature measurement appearance of hole bottom temperature. The temperature tester comprises: portable temperature acquisition instrument 1, can fix a position telescopic link 3, three-core tetrafluoro temperature compensation line 2, thermal resistance sensor 4, can fix a position the length of telescopic link 3 through the change, place the drilling different degree of depth with the thermal resistance sensor 4 of temperature measurement, be connected thermal resistance sensor 4 with portable temperature acquisition instrument 1 through three-core tetrafluoro temperature compensation line 2 to realize the survey of drilling bottom temperature.
The device is used for measuring the original temperature or the hole bottom temperature of different lithology and different drilling depths by changing the length of the positioning telescopic rod 3.
