Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic exploration, in particular to an electromagnetic exploration device with an anti-slip structure. Background Art

[0002] Currently, some exploration sites require the use of electromagnetic survey instruments. Electromagnetic methods, based on differences in the electromagnetic properties of a medium, achieve certain exploration objectives by observing and studying the spatial distribution and temporal variations of artificial or natural alternating electromagnetic fields. Based on how the electromagnetic field varies with frequency and time, electromagnetic methods can be categorized into frequency-domain and time-domain methods.

[0003] For example, an anti-interference downhole transient electromagnetic exploration device disclosed in authorization announcement number CN216848185U facilitates improving the cable clamping force and improving the stability of the connection between the cable and the transient electromagnetic exploration instrument by setting a clamping component and a friction block. In addition, the friction block made of rubber material facilitates increasing the friction between the cable and the device, thereby solving the problem of signal transmission interruption caused by the cable being pulled and separated from the connection end, thereby improving work efficiency.

[0004] However, the above-mentioned anti-interference function mainly relies on the friction of rubber to prevent the cable from abnormally detaching. It is still easy to detach under the interference of external forces, making the overall anti-interference ability relatively general. For this reason, we propose an electromagnetic exploration device with an anti-detachment structure. Utility Model Content
