Description

Technical Field

[0001] This utility model relates to the field of transient electromagnetic detection equipment, specifically a transient electromagnetic continuous detection device. Background Technology

[0002] Transient electromagnetic methods are physical exploration methods that use coils or grounded electrodes to observe secondary eddy current fields. Currently, the method for dynamic measurement of transient electromagnetic methods is to use a towed or hand-pushed non-magnetic measuring vehicle to fix the transmitting and receiving coils on the measuring vehicle for data acquisition. However, the measurement angle of the fixed transmitting and receiving coils cannot be adjusted during the measurement, resulting in incomplete data collection.

[0003] According to a patent document with publication number CN207752164U, a transient electromagnetic detection device includes a coil device. The coil device includes a coil mounting frame that can rotate the coil device 180°. Two transmitting coils are fixed on the coil mounting frame. The two transmitting coils include a first transmitting coil and a second transmitting coil, which can generate opposite magnetic fields at their respective coil centers at any time during power supply and are parallel but not coplanar. That is, the first transmitting coil and the second transmitting coil are located in a first plane and a second plane, respectively. This technical solution employs a telescopic adjustable structure and a rotationally adjustable structure, allowing adjustment of parameters such as the spacing between the two transmitting coils, the spacing between the receiving coil and the transmitting coil, and the spacing between the transmitting coil and the receiving coil and the ground. This flexibility allows it to meet different environments, detection tasks, and targets. However, while this solution achieves spacing adjustment, it cannot quickly adjust the measurement direction and angle during use, which is inconvenient. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a transient electromagnetic continuous detection device, including a base 1, an opening 10 at the top of the base 1, a rotating seat 2 rotatably mounted on the side of the opening 10, an arc-shaped plate 3 fixed on the rotating seat 2, a fixed seat 4 movably mounted between the arc-shaped plates 3, a positioning component 8 and a threaded tube 6 respectively mounted on the bottom of the fixed seat 4, a threaded rod 7 rotatably mounted inside the threaded tube 6, and a movable seat 9 fixed to one end of the threaded rod 7 and the positioning component 8. The movable seat 9 is installed inside the opening 10. A slot 21 is opened on the inner wall of the arc plate 3. A support mechanism 22 is fixed inside the slot 21. A fixing block 23 is fixed at one end of the support mechanism 22. A fixing hole 24 is opened on the side of the fixing block 23. A moving wheel 12 is fixed at the bottom of the base 1. The support mechanism 22 is a support spring. The support spring pushes the fixing block 23 to move upward. When the threaded column 5 loses its limit on the fixing block 23, the fixed seat 4 moves upward to return to its original position and completes the fine adjustment of the position height of the movable seat 9.

[0026] In this embodiment, a rotating column 17 is welded to the side of the fixed base 4. The rotating column 17 is movably installed inside the fixed hole 24. A limit hole 18 is opened on the rotating column 17. A threaded seat is fixed to the top of the arc plate 3. A threaded column 5 is rotatably installed inside the threaded seat. One end of the threaded column 5 is movably installed on the top of the fixed block 23. A fixed groove 19 is opened at the bottom of the movable base 9. A coil 20 is fixedly installed inside the fixed groove 19. A support frame 13 is welded to the base 1. A handrail 14 is fixed to the side of the support frame 13. A fixed plate 15 is fixed between the support frames 13. A movable box 16 is movably installed on the side of the fixed plate 15. The fixed plate 15 moves under the push of the lifting mechanism 27. The lifting mechanism 27 is a linear reciprocating electric push rod. The display mechanism 25 is exposed and opened under the push of the lifting mechanism 27. The display mechanism 25 is a touch screen display screen. The measured data is displayed through the display mechanism 25.

[0027] In this embodiment, the inner wall of the support frame 13 has an installation groove, and a lifting mechanism 27 is fixed inside the installation groove. A protrusion 26 is fixed to one end of the lifting mechanism 27, and the protrusion 26 is fixed to the side of the movable box 16. A display mechanism 25 is fixedly installed on the movable box 16. A connecting seat 28 is fixed to the bottom of the rotating seat 2. The connecting seat 28 is movably installed on the base 1. A fixing bolt 11 is rotatably installed at one end of the base 1. One end of the fixing bolt 11 is movably in contact with the connecting seat 28. A connecting hole 29 is opened at the top of the fixing block 23. A groove 30 is opened at the bottom of the fixing hole 24. The groove 30 is movably in contact with one end of the threaded column 5. After the fixing bolt 11 rotates, it contacts the connecting seat 28. The compressive force generated by the fixing bolt 11 limits and fixes the connecting seat 28. After the connecting seat 28 is limited, the rotating seat 2 is simultaneously limited and fixed.

[0028] Working principle: During use, the installation direction of the movable seat 9 is rotated according to the detection position. When it is necessary to measure the side of the base 1, the movable seat 9 is moved to the top of the rotating seat 2, and the threaded column 5 is rotated upward. The threaded column 5 rotates out of the limiting hole 18 and the groove 30, and the rotating column 17 loses its limiting force. The fixed seat 4 drives the movable seat 9 to rotate 90 degrees through the rotating column 17. After the movable seat 9 rotates 90 degrees, the side measurement is completed. After the position of the movable seat 9 is adjusted, the threaded column 5 moves downward. The threaded column 5 moves downward and enters the limiting hole 18 and the groove 30 through the connecting hole 29 to limit the rotating column 17. After the threaded column 5 limits the rotating column 17, the threaded column 5 rotates again to push the fixed block 23 to move up and down inside the slot 21. The fixed block 23 moves downward. When the support mechanism 22 is compressed, the rebound force of the support mechanism 22 provides limiting support for the fixed seat 4 and the fixed block 23. After the position of the movable seat 9 is adjusted, the lifting mechanism 27 is activated to push the protrusion 26 and the movable box 16 upward. After the movable box 16 moves upward, the display mechanism 25 is opened to view the measured data. When measuring the ground, the fixed seat 4 is rotated 90 degrees so that the movable seat 9 is at the top of the opening 10. The threaded tube 6 is rotated to push the threaded rod 7 downward. After the threaded rod 7 moves downward, it enters the interior of the opening 10. The inner wall of the opening 10 contacts the movable seat 9. The distance of contact with the ground is controlled by the up and down movement of the movable seat 9. The opening 10 limits and fixes the movable seat 9. When not in use, the movable seat 9 can be moved into the interior of the opening 10 for shielding and protection.
