[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a geophysical exploration detector. Figure 1 A geophysical exploration detector includes a detector body 1 and a plurality of mounting brackets 2. When in use, the detector body 1 can be suspended by a steel cable or other traction rope and dropped into a hole. The mounting bracket 2 includes a connecting ring 21 and a plurality of telescopic adjustment rods 22. The connecting ring 21 is installed on the detector body 1 and the two are coaxially arranged. The telescopic adjustment rod 22 is arranged around the detector body 1, one end of the telescopic adjustment rod 22 is connected to the connecting ring 21, and the telescopic adjustment rod 22 extends parallel to the radial direction of the connecting ring 21.

[0032] Reference Figure 1 The mounting bracket 2 is provided with a plurality of guide wheels 3 , and the plurality of guide wheels 3 are respectively arranged on a plurality of telescopic adjustment rods 22 , and the guide wheels 3 are installed on one end of the telescopic adjustment rod 22 away from the connecting ring 21 .

[0033] When the suspended geophone body 1 gradually falls in the hole, the guide wheel 3 on the mounting bracket 2 can contact the inner wall of the hole and roll, reducing the possibility of the geophone body 1 swinging and the possibility of the geophone body 1 directly hitting the inner wall of the hole or being scratched by the inner wall of the hole. The possibility of damage to the geophone body 1 is reduced and the service life is increased.

[0034] In addition, the length of the telescopic adjustment rod 22 itself can be adjusted according to actual needs, so as to adapt to exploration operations in holes of different diameters and increase the adaptability range.

[0035] Reference Figure 1 The connecting ring 21 includes a pair of arc-shaped clamping strips 211 and a plurality of connecting bolts 212. The two clamping strips 211 are clamped together on the detector body 1, so that the two clamping strips 211 are spliced ​​together into a ring structure. The connecting bolts 212 connect the facing ends of the two clamping strips 211 to each other to achieve the fixing of the clamping strips 211. During installation, it is only necessary to clamp the two clamping strips 211 on the detector body 1 and then tighten the connecting bolts 212, making the installation process more convenient.

[0036] Reference Figure 1 and Figure 2The telescopic adjustment rod 22 includes a first support rod 221, a second support rod 222 and an adjustment nut 223. The first support rod 221 and the second support rod 222 are both parallel to the radial extension of the connecting ring 21. One end of the first support rod 221 is connected to the clamping bar 211, and the second support rod 222 is coaxially sleeved and slidably connected to the other end of the first support rod 221. The adjustment nut 223 is coaxially rotatably connected to the second support rod 222, and the adjustment nut 223 is sleeved and threadedly connected to the first support rod 221. The guide wheel 3 is installed at one end of the second support rod 222 away from the first support rod 221.

[0037] Reference Figure 2 In addition, a limiting groove 2211 extending along the length direction of the first support rod 221 is formed on the outer wall of the first support rod 221 , and the second support rod 222 is clamped in the limiting groove 2211 .

[0038] When in use, the adjusting nut 223 is rotated to control the second support rod 222 to slide relative to the first support rod 221, thereby adjusting the overall length of the telescopic adjustment rod 22, so as to facilitate the adjustment of the position of the guide wheel 3 according to actual needs, and to facilitate the use of holes of different diameters. In addition, when the adjusting nut 223 is rotated to control the sliding of the second support rod 222, the limiting groove 2211 can limit the rotation of the second support rod 222, so that the sliding process of the second support rod 222 is more stable; and the possibility of the guide wheel 3 swinging due to the rotation of the second support rod 222 is reduced, so as to ensure the stability of the guide wheel 3 when in use.

[0039] In other embodiments, the adjusting nut 223 may be replaced by a bolt. In this case, the first support rod 221 or the second support rod 222 is provided with a plurality of adjusting holes distributed along its axial direction, and the bolt is simultaneously passed through the first support rod 221 and the second support rod 222, and the bolt is passed through the adjusting hole.

[0040] Reference Figure 2 The first support rod 221 is detachably connected to the clamping bar 211, and a plug plate 2212 is fixed to one end of the first support rod 221 facing the clamping bar 211. The clamping bar 211 is provided with a plurality of slots 213, and the plug plate 2212 is plugged into the slots 213. The plug plate 2212 is provided with a locking screw 2213, and the locking screw 2213 is simultaneously penetrated through the plug plate 2212 and the clamping bar 211. Then, the first support rod 221 is detachably fixed to the clamping bar 211 by the locking screw 2213, so as to facilitate the disassembly, storage or replacement of the telescopic adjustment rod 22. In addition, during the installation process, before tightening the locking screw 2213, the plug plate 2212 needs to be plugged into the slot 213 first, so as to pre-position the plug plate 2212 and facilitate the installation of the locking screw 2213.

[0041] Reference Figure 3, a movable column 224 is provided at one end of the second support rod 222 away from the first support rod 221, and a support plate 2241 is provided inside the end of the second support rod 222 away from the first support rod 221. The movable column 224 is axially arranged in the second support rod 222 and slidably connected to the support plate 2241. The movable column 224 is set as a cylindrical structure. At this time, a sliding groove extending in the length direction of the movable column 224 is provided on the outer wall of the movable column 224, and the support plate 2241 is clamped in the sliding groove; of course, the movable column 224 can also be set as a prismatic structure. The guide wheel 3 is rotatably connected to the end of the movable column 224 away from the second support rod 222.

[0042] Reference Figure 3 The movable column 224 is fixed with a limit plate 2242, which is located on the side of the support plate 2241 facing the first support rod 221. The movable column 224 is sleeved and threaded with an adjustment plate 2243, which is located on the side of the support plate 2241 away from the first support rod 221.

The push spring 225 is coaxially sleeved on the movable column 224, and the two ends of the push spring 225 are respectively abutted against the adjustment plate 2243 and the support plate 2241.

[0043] When in use, the push spring 225 can push the adjustment plate 2243, so that the movable column 224 has a tendency to slide toward the inner wall of the hole, thereby ensuring that the guide wheel 3 is firmly in contact with the inner wall of the hole. At the same time, it also has a buffering effect when the guide wheel 3 hits the inner wall of the hole, reducing the possibility of damage to the guide wheel 3 and the detector body 1.

[0044] In addition, the limit plate 2242 has a limiting effect on the sliding range of the movable column 224, reducing the possibility of the movable column 224 detaching from the second support rod 222. Moreover, the maximum distance between the adjustment plate 2243 and the support plate 2241 can be adjusted by rotating the adjustment plate 2243, so as to adjust the deformation of the initial position of the push spring 225 according to actual needs, thereby adjusting the effect of the push spring 225 and increasing adaptability.

[0045] The implementation principle of a geophysical exploration detector in the embodiment of the present application is as follows: when the suspended detector body 1 gradually falls in the hole, the guide wheel 3 on the mounting bracket 2 can contact the inner wall of the hole and roll, reducing the possibility of the detector body 1 directly hitting the inner wall of the hole or being scratched by the inner wall of the hole, reducing the possibility of damage to the detector body 1 and increasing its service life.
