[0002] In the field of geological exploration, electromagnetic detectors are widely used in field operations such as mineral resource exploration, groundwater surveys, geological structure analysis, and environmental engineering monitoring. Especially in complex terrains such as mountains, forests, farmland, or abandoned mining areas, detection operations often face practical difficulties such as uneven ground, vegetation cover, crisscrossing gullies, and numerous narrow passages.

[0003] Traditional handheld electromagnetic detectors rely on operators to carry or shoulder the equipment throughout the entire process. This is not only labor-intensive, but also makes it easy to detour when crossing ditches, rock piles, or narrow areas due to operational inconvenience, which seriously affects detection efficiency. At the same time, it is difficult to maintain a constant distance between the detector head and the ground. When passing through potholes, it is easy to touch the ground, impact, or experience severe vibration, which can damage the sensitive elements of the detector or cause data distortion, seriously affecting the stability and service life of the equipment.

[0004] This utility model provides a geological exploration electromagnetic detector, including a support rod, on which a receiver is fixedly installed. A sliding sleeve is slidably fitted at the bottom of the support rod. An adjustable moving mechanism is provided on one side of the sliding sleeve, and a detection mechanism is provided on the other side. The user can assist the detection mechanism in moving by pushing the adjustable moving mechanism.

[0005] Preferably, the adjustable moving mechanism includes an adjusting plate fixed to one side of the sliding sleeve. The adjusting plate has a pair of oppositely arranged sliding grooves, and a bracket is slidably fitted in each sliding groove. One end of the bracket extends downward and is rotatably connected to the moving wheel.

[0006] Preferably, the upper ends of the two brackets are connected to the two racks by bolts, the bottom of the two racks slides in fit with the limiting groove opened on the upper surface of the adjustment plate, and a gear is rotatably arranged in the middle of the adjustment plate, with the two racks meshing with the two sides of the gear respectively.

[0007] Preferably, a U-shaped plate is fixedly provided on the upper side of the adjustment plate, and a second gear is rotatably provided on the U-shaped plate, with the shaft of the second gear connected to the shaft of the first gear.

[0008] Preferably, the U-shaped plate has a groove, a positioning block is slidably disposed in the groove, a spring is connected between the inner wall of the groove and the positioning block, and the positioning block is inserted into the teeth of the gear to achieve positioning.

[0009] Preferably, the detection mechanism includes an adjusting sleeve fixed to the other side of the sliding sleeve, and a slider is slidably disposed inside the adjusting sleeve, the slider being connected to the detector.

[0010] Preferably, vertical grooves are provided on both sides of the adjusting sleeve, and the two sides of the slider slide in cooperation with the vertical grooves.

[0011] Preferably, the upper side of the slider is fixedly connected to the lower end of the rack two, and the upper end of the rack two passes through the adjusting sleeve and is slidably connected to the adjusting sleeve.

[0012] Preferably, a positioning rod is slidably disposed in the through groove opened at the upper end of the adjusting sleeve, and a spring is connected between the inner wall of the through groove and the positioning rod, and the positioning rod is engaged with the tooth groove of the rack.

[0013] Preferably, the bottom of the support rod is provided with two oppositely arranged ring plates, the sliding sleeve is sleeved on the support rod body between the two ring plates and can slide along the axial direction, a plurality of dampers are provided between the sliding sleeve and the upper ring plate, and a plurality of springs are provided between the sliding sleeve and the lower ring plate.

[0014] This utility model provides a geological exploration electromagnetic detector, which, compared with the prior art, has the following advantages:

[0015] 1. This utility model features movable wheels on the sliding sleeve at the bottom of the support rod, and width adjustment via a groove on the adjustment plate. This allows the equipment to flexibly adapt to the specific width requirements of the terrain. This design allows operators to easily pass through environments with different width restrictions without having to detour, improving the ease of operation of the equipment. Operators only need to push the equipment lightly to complete the detection task of a large area without having to frequently detour around obstacles, thereby reducing the difficulty of operation and physical exertion. It is suitable for long-term, large-scale field exploration operations.

[0016] 2. The detection mechanism of this utility model includes a slider installed inside the adjusting sleeve and a detector connected to the slider, enabling the detector to move flexibly up and down in the vertical direction to adapt to different terrain undulations. Through the insertion and cooperation of rack two and positioning rod under the action of spring three, the position of slider and detector can be locked in segments to ensure that the detector always maintains a suitable height above the ground during operation, avoiding direct collision or friction with the ground. At the same time, spring one and damper are provided between the sliding sleeve and the support rod to form a flexible buffer support structure. When the equipment travels on uneven roads or low-lying areas, it can effectively absorb the impact vibration from the ground, suppress violent jumping, and prevent the detector from being damaged due to excessive instantaneous force. Especially when the moving wheel crosses potholes or obstacles, spring one and damper work together to reduce the downward tendency of the detection mechanism, thereby fully protecting the detector and extending its service life.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-2This utility model provides a geological exploration electromagnetic detector, including a support rod 1, a receiver 2, a sliding sleeve 3, an adjustable moving mechanism, and a detection mechanism.

[0030] The support rod 1 is a hollow metal tube used to support the overall structure and for operators to hold and push. A receiver 2 is fixedly installed on the upper part of the support rod 1. The receiver 2 is used to collect and process electromagnetic signals from the detector 20. Its position is far away from ground interference sources, which helps to improve the stability of signal reception and the signal-to-noise ratio.

[0031] like Figure 3 and Figure 5 As shown, two opposing ring plates 4 are provided at the bottom of the support rod 1, forming a limiting interval between the two ring plates 4. The sliding sleeve 3 is sleeved on the support rod 1 within this interval and can slide up and down along the axial direction. In order to realize the buffering and reset functions, several dampers 5 are provided between the sliding sleeve 3 and the ring plate 4 located above. The dampers 5 adopt hydraulic or rubber buffer structure to reduce the impact when the sliding sleeve 3 moves upward.

[0032] Several springs 6 are provided between the sliding sleeve 3 and the ring plate 4 located below. The springs 6 provide an upward elastic restoring force, so that the sliding sleeve 3 can automatically rebound after being compressed, forming a flexible suspension system that effectively absorbs the vibration caused by uneven ground and protects the detection components.

[0033] like Figure 4 As shown, an adjusting plate 7 is fixedly connected to one side of the sliding sleeve 3. The adjusting plate 7 serves as the mounting base for the adjustable moving mechanism. A pair of oppositely arranged sliding grooves 8 are provided on the adjusting plate 7. A bracket 15 is slidably fitted in each sliding groove 8. The upper end of the bracket 15 is fitted with the sliding groove 8, and the lower end extends downward and is rotatably connected to a moving wheel 16. The moving wheel 16 can be a rubber wheel or a polyurethane wheel, which has good wear resistance and shock absorption performance. By adjusting the lateral position of the two brackets 15 in the sliding groove 8, the wheel distance between the two moving wheels 16 can be changed, thereby adapting to passageways of different widths, such as narrow ditches or areas with dense obstacles.

[0034] like Figure 6 As shown, in order to achieve synchronous adjustment, the upper ends of the two brackets 15 are respectively connected to racks 9 by bolts. The two racks 9 are arranged in parallel, and their bottoms are embedded in the limiting grooves opened on the upper surface of the adjustment plate 7 to ensure smooth sliding.

[0035] The middle part of the adjusting plate 7 is equipped with a gear 11 that rotates through a shaft. Two racks 9 mesh with the left and right sides of the gear 11 respectively to form a synchronous transmission structure. When the gear 11 is rotated, the two racks 9 will move in opposite directions synchronously, thereby driving the two side supports 15 to move closer or further away synchronously, so as to realize the rapid and symmetrical adjustment of the wheel track.

[0036] Furthermore, a U-shaped plate 10 is fixedly installed on the upper side of the adjusting plate 7, and a gear 12 is rotatably installed between the two side walls of the U-shaped plate 10. The rotating shaft of the gear 12 is coaxially connected with the rotating shaft of the gear 11, which facilitates external force adjustment.

[0037] like Figure 7 As shown, a groove is provided on one side wall of the U-shaped plate 10, and a positioning block 13 is slidably disposed in the groove. A spring 14 is connected between the inner wall of the groove and the positioning block 13. The spring 14 provides elastic force to make the positioning block 13 extend outward. The end of the positioning block 13 can be inserted between the teeth of the gear 12 to lock the gear 12 and prevent the wheel track from changing unexpectedly due to vibration during operation. During operation, simply press the positioning block 13 to disengage it from the teeth, and the gear 12 can be rotated for adjustment. After releasing, it automatically resets and locks. The operation is simple and reliable.

[0038] like Figure 8 As shown, an adjusting sleeve 17 is fixedly connected to the other side of the sliding sleeve 3. The adjusting sleeve 17 is a vertically arranged structure, and a slider 18 is slidably arranged inside it. Vertical grooves are opened on both sides of the adjusting sleeve 17, and lugs are provided on both sides of the slider 18. The lugs are embedded in the vertical grooves and can slide up and down along them to ensure that the slider 18 moves smoothly without deflection. A detector 20 is connected to the lower end of the slider 18. The detector 20 is an electromagnetic induction probe used to transmit signals to the ground and receive reflected signals.

[0039] The upper end of the slider 18 is fixedly connected to the lower end of the rack 19. The rack 19 is arranged vertically, and its upper end passes through the top of the adjusting sleeve 17 and slides in cooperation with the adjusting sleeve 17. A positioning rod 21 is slidably arranged in the through groove opened at the upper end of the adjusting sleeve 17. A spring 22 is connected between the inner wall of the through groove and the positioning rod 21. The spring 22 pushes the positioning rod 21 to be inserted horizontally into the tooth groove of the rack 19 to achieve segmented height locking.

[0040] When it is necessary to adjust the height of the detector 20 off the ground, push the positioning rod 21 outward to disengage it from the tooth groove of the rack 2 19, pull the rack 2 19 upward, and after sliding it to the target position, the positioning rod 21 will automatically insert into the new tooth groove to complete the height fixation and ensure that the detector 20 is always at the optimal working distance.

[0041] In summary, the operator can adjust the wheel track of the adjustable moving mechanism to adapt to the terrain width and push the equipment forward. The detection mechanism automatically adjusts its height according to the undulations of the ground under the buffering effect of spring 6 and damper 5. At the same time, the height is locked in segments through the cooperation of rack 19 and positioning rod 21. Throughout the process, the moving wheel 16 undertakes the main support and movement functions, reducing the labor intensity of the operator. The flexible suspension structure effectively protects the detector 20 from impact damage, realizing efficient, safe and stable field electromagnetic detection operations.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
