Abstract
The utility model relates to a ground temperature measuring device. The ground temperature measuring device comprises a temperature measuring tube, a temperature measuring rope and temperature measuring sensors. The temperature measuring tube is a sealed tube with an upper opening; the temperature measuring sensors are staggerly arranged on the temperature measuring rope; the temperature measuring rope is coaxially and vertically placed in the temperature measuring tube; hair balls are coaxially installed at the temperature measuring rope between adjacent temperature measuring sensors; the hair balls are in clearance fit with the inner wall of the temperature measuring tube; and the bottom end of the temperature measuring rope is equipped with a lead sinker. According to the ground temperature measuring device of the utility model, the interior of the temperature measuring tube is divided into a plurality of segments, and the air for transferring temperature in each segment does not circulate, so underground actual temperature can be accurately measured; and the hair balls are adopted to obstruct the circulation of a plurality of segments of air in the temperature measuring tube, and the smoothness of the surfaces of the hair balls are high, so the temperature measuring rope can be put inside the temperature measuring tube with easiness, and further, the hair balls are tightly connected with the temperature measuring tube wall, thereby enabling favorable heat insulation effect, and therefore, the ground temperature measuring device can accurately measure ground temperatures which changes with depths.
Description
Technical field
The utility model belongs to the engineer geological prospecting field, relates to temperature survey, especially a kind of geothermometry device.
Background technology
Carry out engineer geological prospecting in tunnel and Permafrost Area, often need to measure the situation that ground temperature changes with the variation of the degree of depth.Traditional geothermometry device comprises temperature tube and thermometric rope, temperature tube is the pipe of side and sealed bottom around, and the thermometric rope is comprised of temperature probe, and temperature probe commonly used is thermistor, a plurality of thermistors are unified into one group by measuring spacing, cross to mould and make the thermometric rope.
The geothermometry device in use, generally first temperature tube is placed in the hole, ground that drills in advance, again the thermometric rope is put into temperature tube and carry out temperature survey, left standstill 24 hours, when treating that temperature tube internal temperature field is identical with temperature tube external temperature field temperature, carry out geothermometry.Because transmitting the medium of temperature in the temperature tube is air, the mobile temperature probe that causes of thermometric inner air tube can not reflect accurately that true ground temperature is with the variation of the degree of depth.When Air Flow was abundant in the temperature tube, the measured temperature variation of different depth was little, therefore can not accurately measure real ground temperature.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can accurately measure the geothermometry device that ground temperature changes with change in depth.
The purpose of this utility model is achieved in that
A kind of geothermometry device, comprise temperature tube, thermometric rope, temperature probe, temperature tube is the sealed tube of upper shed, temperature probe is installed at the interval on the thermometric rope, this thermometric rope is coaxial vertically to be placed in the temperature tube, it is characterized in that: the thermometric rope between adjacent temperature probe is coaxially installed with ball top, and ball top and temperature tube inwall clearance fit are installed a plummet in thermometric rope bottom.
And described ball top is made by animal hair or feather.
Advantage of the present utility model and good effect are:
1, this device will be set to independently space of multistage in the temperature tube, transmits the atmosphere draught-free of temperature between every section, can accurately measure underground actual temperature.
2, the ball top that adopts of this device can cut off the circulation between the multistage air in the temperature tube, because the smoothness on ball top surface is easy to the thermometric rope is placed on temperature tube inside, and ball top is connected closely with the thermometric tube wall, and thermal insulation is effective.
3, the thermometric rope bottom of this device arranges a plummet, this plummet is for putting the rope gravity source, not only can easily the thermometric rope be placed in the temperature tube, and the thermometric rope is fully vertically trailed, the distance of two temperature probes can be accurately measured, thereby accurate subsurface temperature can be conversed.
4, the utility model design science is simple in structure, and is with low cost, convenient operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with the embodiments the utility model is described further below by accompanying drawing, need to prove, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of geothermometry device as shown in Figure 1, comprises temperature tube 1, thermometric rope 2, temperature probe 4, temperature tube is the sealed tube of upper shed, temperature probe is installed at the interval on the thermometric rope, and this thermometric rope is coaxial vertically to be placed in the temperature tube, and the upper end of thermometric rope connects a multimeter 7.
Innovative point of the present utility model is:
Thermometric rope between adjacent temperature probe is coaxially installed with ball top 3, and this ball top can be one, also can be a plurality of, set according to the actual needs, and be one shown in the present embodiment accompanying drawing; Ball top and temperature tube inwall clearance fit are installed a plummet 5 in thermometric rope bottom.
In the present embodiment, temperature tube is the pipe of side and sealed bottom around, and temperature tube is 50 millimeters of overall diameters, 4 millimeters of wall thickness, and the low temperature material that interior diameter is 42 millimeters is made.Vertically place during temperature tube work, penetrate the thermometric rope from the upper end open of temperature tube, between the two adjacent temperature probes ball top is being installed radially on this thermometric rope, this ball top is made by good heat-insulation effect, bulk, resilient animal hair or feather, it is radial that hair is, 46 millimeters of the fluffy diameters of ball top, and ball top tightens up 41 millimeters of diameters, lining rope length is 15 meters, and the plummet quality is 2 kilograms.
Temperature probe is thermistor, and a plurality of thermistors are installed on the thermometric rope by measuring intervals.
The thermometric rope cooperates the ganoid characteristics of ball top under the effect of putting rope gravity source plummet, can very easily the thermometric rope be placed in the temperature tube, and the hair of ball top can be adjacent to the effect of playing air-isolation at the thermometric tube wall.
The course of work of the present utility model is:
1, first temperature tube is placed in the hole, ground 6 that drills in advance, again the thermometric rope is put into temperature tube, plummet and the temperature tube sealed bottom of thermometric rope lower end leave the gap, leave standstill 24 hours, when treating that temperature tube internal temperature field is identical with temperature tube external temperature field temperature, carry out geothermometry.
2, draw the resistance value that wire is measured thermistor with multimeter by thermometric rope upper end, according to the resistance value of demarcating and the relation of temperature, calculate the high temperature value of each thermistor relative position, twice of horizontal survey is with the checking measurements result.
3, measure and to install taking-up after complete.
Acting as of the utility model ball top:
Ball top becomes independently space of multistage with the temperature tube internal interval, the adjacent atmosphere draught-free that independently transmits temperature between the space, because the smoothness on ball top surface is easy to the thermometric rope is placed on temperature tube inside, and fluffy ball top and temperature tube inwall paste closely, thermal insulation is effective, can accurately measure the ground temperature that changes with change in depth.
