Description

Technical Field

[0001] This utility model belongs to the field of transient electromagnetic instrument technology, specifically relating to a transient electromagnetic instrument coil holder. Background Technology

[0002] Transient electromagnetic instruments (TEM) are electromagnetic methods used in geophysical exploration. They infer the electrical structure, distribution, and characteristics of underground geological bodies by transmitting a pulsed magnetic field into the ground and measuring the changes in the secondary induced eddy current field generated in the underground conductive medium over time. The TEM coil frame is a key component of the instrument used to support and fix the transmitting and receiving coils.

[0003] Conventional transient electromagnetic instrument coil holders are primarily suitable for ground-based measurement operations. In typical measurement environments, the coil holder is placed stably on the ground for geophysical exploration. However, in specific locations, such as when acquiring electromagnetic data in a specific vertical direction, conducting three-dimensional electromagnetic detection of a specific area, or when the target has certain height characteristics, it is necessary to erect the coil on the ground to change the measurement angle and range, thereby obtaining more comprehensive underground electromagnetic information. However, currently used transient electromagnetic instrument coil holders have a relatively simple structural design, making it difficult to quickly and conveniently switch between ground-based and vertical measurement environments. This limits the application of transient electromagnetic instruments in more complex scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a transient electromagnetic instrument coil holder to solve the problem mentioned in the background art that the existing coil holders have a single detection function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transient electromagnetic instrument coil frame, comprising symmetrically arranged rods; one end of each rod has a through hole, and a sliding groove communicating with the through hole is provided on the side of the rod; a vertically lifting insertion rod is provided in the through hole, and an adjustment part is connected to the insertion rod; the adjustment part extends through the sliding groove to the outside of the rod, and the lifting of the insertion rod is achieved through the adjustment part, thereby achieving the concealed placement or extension of the insertion rod to be fixed to the ground;

[0006] The surface of the rod is also equipped with multiple limiting components, each containing a coil, which is used to store the coil.

[0007] Preferably, the adjusting part includes a connecting column that passes through the slide groove. One end of the connecting column is fixedly connected to the insert rod, and the other end is rotatably connected to a pedal. The bottom of the pedal is limited by the top of the connecting column in a horizontal state. Therefore, when the insert rod needs to be inserted into the ground, the pedal is stepped on. At this time, the pedal will rotate downward until it rotates to a horizontal position. At this time, the pedal can drive the connecting column and the insert rod to move downward and insert into the ground, thereby turning the entire rod into a vertical state.

[0008] Preferably, the top of the end of the connecting post that protrudes outside the rod body has a notch, and the two sides of one end of the pedal are located on the two sides of one end of the connecting post. The two sides of one end of the pedal extend outward and a groove is formed in the middle of one end. The groove here is fitted on both sides of the connecting post, and the pedal and the connecting post are connected by a through shaft.

[0009] Preferably, the top of the pedal is formed with an arc groove, the curvature of which is equal to the outer curvature of the rod, so that the pedal can fit against the outer wall of the rod.

[0010] Preferably, one end of the pedal has an inner groove, and a magnetic plate is inserted into the inner groove. The magnetic plate is bonded to the pedal. When the pedal is not in use, the pedal is rotated upward, and then the arc groove fits into the rod body and is magnetically connected to the surface of the rod body through the magnetic plate.

[0011] Preferably, the limiting component includes multiple connecting sleeves fixed to the rod body, with a hook connected to the bottom of each connecting sleeve. A Velcro fastener passes through the opening of the hook, and the end of the Velcro fastener is fastened by stitching or a sleeve. The sleeve is a frame-shaped metal strip. By squeezing the metal strip, the metal strip deforms and shrinks inward, thereby locking one end of the Velcro fastener. The Velcro fastener is a self-adhesive structure. In the connection with the coil, the coil is inserted into the hook, and then the coil is tightened by the Velcro fastener.

[0012] Preferably, the insertion rod is generally conical, and a cylinder is formed at the top of the insertion rod (not shown in the figure). The outer diameter of the cylinder is equal to the inner diameter of the through hole, thereby ensuring that the insertion rod can move vertically up and down in the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a retractable insert is added to one end of the rod. When routine measurements are required to be performed flat on the ground, the insert can be hidden inside the rod, without affecting the normal placement and use of the coil holder, ensuring stable measurement. However, when encountering specific locations where the coil needs to be erected on the ground to adapt to different testing requirements, the insert hidden inside the rod can be unfolded and extended, allowing the coil holder to be securely inserted into the ground. In this way, the retractable insert design enables the coil holder to flexibly switch between two different testing environments: flat ground measurement and vertical ground measurement. This effectively compensates for the shortcomings of existing transient electromagnetic instrument coil holders and improves their functionality. Attached Figure Description

The bottom of the foot pedal 102 is limited by the top of the connecting post 105 in a horizontal state. Therefore, when the insertion rod 103 needs to be inserted into the ground, the foot pedal 102 is stepped on. At this time, the foot pedal 102 will rotate downward until it rotates to a horizontal state. At this time, the foot pedal 102 can drive the connecting post 105 and the insertion rod 103 to move downward and insert into the ground, thereby changing the entire rod 100 into a vertical state.

[0029] In this embodiment, preferably, the top of the end of the connecting post 105 that protrudes from the outside of the rod body 100 has a notch, and the two sides of one end of the pedal 102 are located on both sides of one end of the connecting post 105.

[0032] In this embodiment, preferably, the limiting component includes multiple connecting sleeves 200 fixed on the rod 100. A hook 201 is connected to the bottom of the connecting sleeve 200. A Velcro 202 passes through the opening of the hook 201. The end of the Velcro 202 is fastened by stitching or a sleeve, wherein the sleeve is a frame-shaped metal strip. By squeezing the metal strip, the metal strip is deformed and retracted, thereby locking one end of the Velcro 202. The Velcro 202 is a self-adhesive Velcro structure. In the connection with the coil 300, the coil 300 is inserted into the hook 201, and then the coil 300 is tightened by the Velcro 202.

[0033] In this embodiment, preferably, the insertion rod 103 is generally conical, and a cylinder is formed at the top of the insertion rod 103 (not shown in the figure).
