Description

Technical Field

[0001] This utility model belongs to the technical field of geological exploration equipment, specifically relating to a device for laying out the coil of a transient electromagnetic instrument. Background Technology

[0002] Transient electromagnetic instruments (TEMs) are among the main instruments used in geophysical exploration, and the transmitting and receiving coils are some of the most crucial components in their operation. In existing technologies, during downward exploration, the TEM coils are manually arranged into a rectangular shape on the ground. This method suffers from several drawbacks: the coils need to be rearranged each time the exploration location is moved, leading to low efficiency; and the irregular coil shape reduces exploration accuracy. During horizontal exploration, at least two workers are required to manually hold and fix the coils in a rectangular shape against the vertical cavity wall. This method also suffers from the same drawbacks: the coils need to be rearranged each time the exploration location is moved, resulting in low efficiency; the need for multiple workers increases labor costs; and the irregular coil shape reduces exploration accuracy. Furthermore, due to the difficulty in effectively arranging the coils on the tunnel roof, upward exploration using TEMs is rarely performed in existing technologies. Utility Model Content

[0003] The purpose of this invention is to provide a device for arranging the coil of a transient electromagnetic instrument, addressing the aforementioned problems in the existing technology.

[0004] The above-mentioned objectives of this utility model are achieved through the following technical means:

[0005] A coil placement device for a transient electromagnetic instrument includes a coil placement frame. The coil placement frame includes a pair of identical base plate supports and multiple elongated sliding frames. The base plate supports are L-shaped, and both the base plate supports and the sliding frames have U-shaped cross-sections. Each base plate support has a sliding frame installed in one of its two support arms. The sliding frames are mounted in the base plate supports, and the sidewalls of the sliding frames are connected to the sidewalls of the support arms of the base plate supports. One end of the sliding frame extending out of the base plate support is a connecting end, and the other end is a sliding end. A support fixing section is provided on the sliding frame connected to one of the base plate supports, and the support fixing section is located at the connecting end of the sliding frame.

[0026] To facilitate understanding and implementation of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to embodiments. The embodiments described herein are only for illustration and explanation and are not intended to limit the present utility model.

[0027] Example 1:

[0028] A coil placement device for a transient electromagnetic instrument includes a coil placement frame. The coil placement frame includes a pair of identical L-shaped base plate supports 1 and two pairs of elongated sliding frames 2. Each base plate support 1 and each sliding frame 2 has a U-shaped cross-section. Each base plate support 1 has one sliding frame 2 in each of its two support arms, allowing the sliding frame 2 to slide within the corresponding support arm of the base plate support 1. Each sliding frame 2 is installed in the support arm of its corresponding base plate support 1, and its two sidewalls are respectively connected to the two sidewalls of the support arm of its corresponding base plate support 1. One end of the sliding frame 2 extending out of the base plate support 1 serves as a connecting end. One end is a sliding end. Two sliding frames 2 connected to one of the substrate supports 1 are each provided with a support fixing section 6. The support fixing section 6 is located at the connecting end of the sliding frame 2. Two sliding frames 2 connected to the other substrate support 1 are each provided with a support fixing hole 7. The support fixing hole 7 is located at the connecting end of the sliding frame 2. By connecting the two support fixing sections 6 to the two support fixing holes 7 respectively, the two substrate supports 1 are spliced ​​together to form a coil laying frame. The size of the coil laying frame can also be adjusted by adjusting the length of the support arm of the sliding frame 2 extending from the corresponding substrate support 1, thereby adapting to coils of different lengths.

[0029] A support rod fixing section 8 is provided at the corner of the substrate support 1, and two support rods 10 are also provided. The top of each of the two support rods 10 is provided with a support rod fixing hole 11 that is adapted to the support rod fixing section 8. The top of the two support rods 10 is connected to the support rod fixing sections 8 of the two substrate supports 1 respectively, thereby connecting the support rods 10 to the coil laying frame. By holding the support rods 10, the coil laying frame is lifted to the required height, thereby completing the upward exploration.

[0030] This invention can prevent personnel from directly contacting the coil and eliminate the possibility of electric shock injury caused by high voltage current.

[0031] Multiple pairs of coil fixing holes 3 are equally spaced along the length direction on the bottom plates of the two substrate supports 1, and multiple pairs of coil fixing holes 3 are equally spaced along the length direction on the top plate of the sliding frame 2. Each pair of coil fixing holes 3 includes two coil fixing holes 3 arranged side by side along the width direction. The spacing between two adjacent pairs of coil fixing holes 3 on the substrate support 1 is the same as the spacing between two adjacent pairs of coil fixing holes 3 on the sliding frame 2. The coil is placed on the sliding frame 2 by passing one end of the binding strap through one of the coil fixing holes 3 of a pair of coil fixing holes 3 on the sliding frame 2, passing it around the coil, and passing it through the other coil fixing hole 3 on the sliding frame 2. Finally, the binding strap is fastened at the bottom of the substrate support 1, thereby completing the fixation of the coil to the coil placement frame.

[0032] In one possible implementation, multiple sliding fixing windows 4 are equally spaced along the length direction on the side wall of the support arm of the substrate support 1, and multiple elastic telescopic blocks 5 are equally spaced along the length direction on the side wall of the sliding frame 2. The fixing part of the elastic telescopic block 5 is connected to the sliding frame 2, and the telescopic part of the elastic telescopic block 5 is adapted to the sliding fixing window 4. The interval between adjacent sliding fixing windows 4 is the same as the interval between adjacent elastic telescopic blocks 5. When the elastic telescopic block 5 of the sliding frame 2 is adapted and connected to the sliding fixing window 4 of the substrate support 1, the positions of each pair of coil fixing holes 3 of the sliding frame 2 correspond to the positions of each pair of coil fixing holes 3 of the substrate support 1. When the sliding frame 2 slides to the required position in the substrate support 1, the elastic telescopic block 5 on the side wall of the sliding frame 2 is inserted into the sliding fixing window 4 on the side wall of the substrate support 1, thereby restricting the movement of the sliding frame 2 and fixing the sliding frame 2 to the substrate support 1. When adjusting the extension length of the sliding frame 2, the elastic telescopic block 5 is pressed to retract into the substrate support 1, thereby allowing the sliding frame 2 to slide along the substrate support 1.

[0033] As one possible implementation, the elastic telescopic block 5 can be a spring top ball. When adjusting the length of the extended sliding frame 2, the sliding frame 2 can be pulled forcefully to slide along the base plate support 1. When it slides to the required position, the spring top ball automatically inserts into the sliding fixed window 4, thereby restricting the movement of the sliding frame 2.

[0034] This invention allows for quick adjustment of the coil layout frame size via the sliding bracket 2, thus accommodating coils of different lengths. The adjustment method is quick, convenient, and saves time and effort.

[0035] As one possible implementation, an arc-shaped coil guide plate 9 is also provided at the corner of the substrate support 1, and the coil smoothly transitions along the arc-shaped coil guide plate 9 at the corner.

[0036] As one possible implementation method, both the substrate support 1 and the sliding frame 2 are provided with length scale lines on their side walls, which can accurately adjust the coil layout size according to exploration needs.

[0037] It should be noted that the embodiments described in this utility model are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described embodiments or use similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
