Geothermal detecting device for geological exploration

Abstract

The invention discloses a geothermal detecting device for geological exploration, and relates to the technical field of geophones. A detecting rotary head is arranged in a drill bit; during downward drilling, a strong drilling force is taken on by the drill bit, a weak impact from grout can merely be taken on by the detecting rotary head, and the detecting rotary head is matched with a drill bit thread to transport and flow the grout better; when the drill bit thread can allow the detecting rotary head to rotate relative to the drill bit, the grout in a detecting hole moves upwards and flows out through a grout outlet hole, and grout temperature at different positions can be detected; and during drilling, according to the change of detected temperature, the detection to geothermy is realized, at the same time, a plurality of geothermal detecting assemblies used to detect temperature are arranged on the detecting rotary head, the accuracy of detecting temperature is ensured, and the performance of detecting the geothermy is improved.

Description

technical field [0001] The invention relates to the technical field of geological detectors, in particular to a geothermal detection device for geological exploration. Background technique [0002] At present, geothermal detection devices are needed when searching for geothermal resources. At present, most geothermal detection devices for geological exploration generally use sensors to measure the infrared of the ground surface for detection, but some geothermal resources emit heat. The surface soil is blocked, and infrared rays cannot be transmitted to the ground, making it impossible for ordinary detectors to detect and thus losing the opportunity to exploit geothermal resources. Therefore, it is necessary to use drilling to detect the geothermal energy corresponding to the deep underground position. After the drilling, if the drill pipe is pulled out and the detection equipment is extended into the ground, it is easy for the soft position to be drilled. If the hole is lo...

Problems solved by technology

[0002] At present, geothermal detection devices are needed when searching for geothermal resources. At present, most geothermal detection devices for geological exploration generally use sensors to measure the infrared of the ground surface for detection, but some geothermal resources emit heat. The barrier of the surface soil, and the infrared rays cannot be transmitted to the ground, making it impossible for ordinary detectors to detect and lose the opportunity to exploit geothermal resources

Therefore, it is necessary to use drilling to detect the geothermal energy corresponding to the deep underground position. After the drilling, if the drill pipe is pulled out and the detection equipment is extended into the ground, it is easy for the soft position to be drilled. The hole is lost, which affects the detection effect. If the geothermal detection head is directly drilled into the ground, the detection head is easily damaged by hard materials such as underground rocks during drilling, which will affect the life of the detection head.
