Steam engine for glacier drilling

Abstract

The invention discloses a steam engine for glacier drilling. The steam engine is structurally characterized in that a finned inner container is fixed by a bracket, and is placed in a combustion chamber, wherein a windshield is arranged at the bottom of the combustion chamber; the combustion chamber is wrapped by a heat-preservation jacket, and is connected with a strap; a water filling pipe with a safety valve and a pressure gauge are connected to the upper part of the finned inner container; one end of a steam outlet pipe is connected with the water filling pipe with the safety valve, and the other end of the steam outlet pipe is sequentially connected with a high-pressure heat-preservation rubber pipe, a drill pipe and a steam nozzle through a steam valve; a heating furnace head is arranged on the lower part of the finned inner container, and is connected with a mountain air pipe and regulation valve and an air bottle. According to the steam engine, the accessory equipment of the steam engine is safely, reliably and conveniently connected through quick joints; the steam engine is convenient to carry, easy to operate, safe and reliable, and can be used for drilling a lining pole hole and a temperature hole under a field condition, and necessary technical guarantee is provided for monitoring glacier changes.

Description

technical field [0001] The invention belongs to a steam engine used for glacier drilling, which is suitable for drilling flower stem holes and temperature holes within 20 meters in glacier areas with no surface moraine or thin surface moraine in high altitude areas. [0002] Background technique [0003] Mass balance is the algebraic sum of glacier surface accumulation and ablation, which reflects the average rise and fall of ice surface per unit area of ​​glacier surface relative to the last glacier mass balance year, and is one of the important parameters to quantify the response of glaciers to climate change; The flower pole method is one of the important means to observe the material balance at present. Years of practice have proved that the steam drilling rig is an effective tool for fixing flower stems on ice with no surface moraine or thin surface moraine, and plays an important role in experimental research in high-altitude areas. [0004] The steam drilling rig cu...

Problems solved by technology

[0004] The steam drilling rig currently used is a fire tube steam drilling rig. Water is stored between the fire tubes and heated by the fire tubes. Since the fire tubes are made of aluminum, the pressure is small, and the maximum working pressure is 4 atmospheres. The drilling depth is shallow and cannot meet the temperature. Second, there are bulky devices, large volume, long heating time, low thermal efficiency, greater pollution to the glacier environment, and certain safety hazards, which limit the occasions and scope of its use, and at the same time greatly limit Related research work in high-altitude areas
