Abstract

The invention provides an electromagnetic detection device and a fishing device, and relates to the technical field of detection equipment. The electromagnetic detection device comprises a main body frame, a walking wheel set and a scanning device. The walking wheel set is installed on the main body frame and used for being attached to the well wall and moving along the well wall. The scanning device is slidably connected to the main body frame and comprises an electromagnetic element and a sensor, the electromagnetic element is used for collecting information of the to-be-fished part and sending the information to the sensor, and the sensor is used for receiving the information and sending the information to the control element. The fishing device comprises the electromagnetic detection device. Through the electromagnetic detection device, the technical problem that in the prior art, accurate detection guiding cannot be achieved in a well with low visibility due to the fact that a machine device carries a traditional imaging device for salvage is solved, and the effect of accurate detection under the condition of low visibility is achieved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to an electromagnetic detection device and a fishing device. Background technique [0002] At present, China's infrastructure is developing rapidly, and piling is required during construction. During piling work, impact drill bits often break and fall into the well. Because the well is full of mud and cannot be extracted (if it is extracted, landslides are very likely to occur). [0003] At present, the existing technology generally uses a mechanical device equipped with a traditional imaging device to detect metal (iron-cobalt-nickel) objects, and determine the approximate shape and position of the object to assist in the next step of construction. However, guidance cannot be accurately implemented in the case of low visibility. Therefore, in the case of low visibility, manual diving is mostly used to salvage. This manual salvage method is dangerous. Once a danger occu...
