A petrol drill for glacier drilling

Abstract

The invention relates to a gasoline drill for glacier drilling. The gasoline drill for glacier drilling is characterized in that a gasoline engine is connected with a variable speed gear, an annular handle is connected with a connecting board, the gasoline engine is fixedly connected with the variable speed gear through the connecting board, a variable speed controller is arranged on the annular handle and connected with the variable speed gear, a gasoline tank is located at the lower portion of the gasoline engine and is connected with the gasoline engine, the gasoline engine is provided with a cord switch, one end of a drill rod penetrates through the connecting board, a pin is plugged into a pin hole in the connection position of the drill rod and the variable speed gear for fastening at the joining position of the drill rod and the variable speed gear, the other end of the drill rod passes through a drill rod bayonet hole, a pin is plugged for fixing when a pin hole in the position, connected with a drill bit, of the drill rod and a pin hole in the position, connected with the drill rod, of the drill bit coincide, and a biconical blade is welded to the embedment port of the drill bit. The gasoline drill for glacier drilling is light and convenient to assemble and disassemble, gasoline serves as a power source of the drill, energy reduction of drills at the cold highland area is avoided, manpower and material resources are saved, and the gasoline drill for glacier drilling is suitable for ice and snow drilling of high cold and high altitude areas.

Description

technical field [0001] The invention belongs to a high-efficiency and convenient gasoline glacier flower rod drill, is an instrument used in the layout of glacier material balance field observation operation points, and belongs to the field of machinery. Background technique [0002] As an indicator of climate change, glaciers / ice sheets store 75% of the global freshwater resources. They are the focus of research on climate change and hydrology and water resources in arid areas, and have important scientific value and social significance. As the most basic physical quantity to describe the characteristics of glaciers and measure the changes of glaciers, the mass balance of glaciers is the key element linking the interaction of atmosphere-cryosphere-hydrosphere. The study of changes in material balance and its relationship with climate and hydrology has also become a hot topic in climate, ocean, cryosphere and other disciplines. One of the key scientific issues prioritized b...

Problems solved by technology

It often requires 3-4 staff members to operate, and there are many connecting links, and the probability of error is high

At the same time, in alpine mountainous areas, the air pressure is different from that in the plains. During the operation, some experience is required to control the air pressure, and there is still a certain degree of danger.

For example, the Chinese invention patent "Hot Water Drill for Glacier Drilling" (patent number: 94231252.X) discloses that the high-pressure steam boiler is a high-pressure vessel, and there have been incidents of steam boiler explosions and injuries in actual field operations

At the same time, due to the uncleanness of the field water, it is easy to cause the blockage of the steam drilling water circulation system, and the small particles produced by the incomplete combustion of the fuel are also easy to cause the blockage of the power system

In addition, there are various manual ice drills. These ice drills are hand drills suitable for drilling holes on river ice. In the special harsh working environment of glaciers, such as high cold, high altitude and hypoxia, manual drilling is very intensive. , the physical exertion of the staff is serious, the drilling efficiency is not high, and the temperature difference between the ice body and the atmosphere can easily cause the liquid water generated during the drilling process to freeze and cause the drill bit to fail to work normally.

And the drilling depth is difficult to exceed 1.5m
