Drill-type instrument for automatically measuring depth of ice layer and measuring method thereof

Abstract

The invention discloses a drill-type instrument for automatically measuring the depth of an ice layer and a measuring method of the drill-type instrument for automatically measuring the depth of the ice layer. The drill-type instrument for automatically measuring the depth of the ice layer comprises an electric drill or an ice breaking machine. A back end processing unit is arranged on the electric drill or the ice breaking machine. The back end processing unit comprises a pressure sensor, a rotary encoder, a single chip microcomputer, an A / D converting module, a wireless communicating module, a display module and a power source module. The pressure sensor is installed on a drill bit of the electric drill or the ice breaking machine, the pressure sensor is connected with the single chip microcomputer through the A / D converting module, the rotary encoder is connected with the electric drill or the ice breaking machine through a wire, and the rotary encoder, the wireless communicating module and the display module are respectively connected to the single chip microcomputer. The drill-type instrument for automatically measuring the depth of the ice layer is improved on the basis of a traditional electric drill or a traditional ice breaking machine, only a back end measuring unit is additionally arranged on the traditional electric drill, the depth value of ice can be automatically calculated at the moment that the ice is drilled through, influence, caused by the factors that water in the Yellow River is large in number of impurities, large in sand content and the like, on measurement is eliminated, and the trouble of manual recording is avoided.

Description

technical field [0001] The invention belongs to the field of ice layer thickness measurement, and in particular relates to a drilling-type ice layer automatic measuring instrument and a measuring method thereof. Background technique [0002] In northern my country, due to the relatively cold winter, the freezing period is long. When the ice layer reaches a certain thickness, vehicles and personnel can pass through the ice directly. This brings great convenience to transportation. However, it can be seen from the returned information that due to the complexity of hydrological and geographical conditions, there are often some areas where the local ice layer becomes thinner (commonly known as Qinggou). The Yellow River is located in the northern region. Due to the large latitude span, ice hazards often occur, which poses a great threat to the lives and property safety of people along the coast. To solve the ice problem, we must first understand the basic conditions of ice, a...

Problems solved by technology

The method of using the electrical conductivity of water to determine the thickness of the ice layer is based on the electrical conductivity of water and ice, which is affected by factors such as the purity of the water and the temperature of the ice layer, especially the contact between the bottom of the ice layer and the thickness of the ice layer. The conductivity change characteristics of the interface are relatively complex, and there is no strict boundary point between conductivity and insulation, which brings difficulties to detection
