[0002] In the prior art, borehole inclination is a phenomenon often encountered in drilling construction. When a borehole inclination occurs, it is very easy to cause the accidents of drill sticking and drill burying. As the exploration work of mineral resources gradually develops towards the deep direction, the increase in borehole depth increases the probability of borehole inclination, resulting in greater difficulty in the anti-inclination and straightness preservation work of boreholes. Therefore, in drilling construction, an inclinometer is usually used to survey boreholes. Specifically, an inclinometer is an instrument used to measure the apex angle and azimuth angle of engineering structures such as boreholes, foundation pits, foundation bases, walls, and dam slopes, and generally includes a reading instrument, a cable, and a probe. Among them, both the upper and lower parts of the probe are provided with rollers that can swing up and down to facilitate the movement of the probe in the borehole.

[0033] Refer to Figure 1 , the probe for borehole survey according to an embodiment of the present invention includes a probe body 100 and a cleaning mechanism.

[0034] Two first rollers 200 are provided on the upper part of the probe body 100, and two second rollers 300 are provided on the lower part of the probe body 100 and are correspondingly arranged directly below the two first rollers 200. One of the first rollers 200 and one of the second rollers 300 are located on one side of the probe body 100, and the other first roller 200 and the other second roller 300 are located on the other side of the probe body 100. Both the first rollers 200 and the second rollers 300 can swing up and down relative to the probe body 100. The cleaning mechanism is provided on the lower part of the probe body 100 and below the second rollers 300, and the cleaning mechanism can clean the sediment on the inner wall of the borehole.

[0035] By providing a cleaning mechanism on the probe body 100 below the first rollers 200 and the second rollers 300, the sediment on the inner wall of the borehole can be cleaned during the borehole survey process, which is beneficial to preventing the first rollers 200 and the second rollers 300 from getting stuck, so that the above-mentioned probe for borehole survey can smoothly move in the borehole, and further beneficial to improving the survey efficiency.

[0036] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, in some of these embodiments, the cleaning mechanism includes two sets of cleaning components 400 disposed directly below the two second rollers 300 in a one-to-one correspondence. The cleaning component 400 includes a bracket and a brush head 410. One end of the bracket is connected to the probe body 100, and the brush head 410 is connected to the other end of the bracket. The cleaning component 400 is located directly below the second roller 300, and the second roller 300 is located directly below the first roller 200. During use, the brush head 410 of the cleaning component 400 can clean the sediment on the moving paths of the first roller 200 and the second roller 300 in the borehole in advance, which helps prevent the first roller 200 and the second roller 300 from getting stuck.

[0037] It should be noted that, in some of these embodiments, the cleaning component 400 further includes an adjustment structure to enable the cleaning component 400 to adapt to boreholes of different diameters, in cooperation with the first roller 200 and the second roller 300 that can swing up and down relative to the probe body 100, so that the above-mentioned probe for borehole exploration can adapt to boreholes of different diameters, which helps improve the versatility of the above-mentioned probe for borehole exploration.

[0038] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, in some of these embodiments, the adjusting structure includes a tension spring 420 and two limiting sliders 430. The bracket includes two connecting rods 440. One end of one connecting rod 440 is rotatably connected to the brush head 410 and one of the limiting sliders 430 respectively, and the two ends of the other connecting rod 440 are rotatably connected to the brush head 410 and the other limiting slider 430 respectively. The probe body 100 is provided with limiting chutes 110 corresponding to the two limiting sliders 430. The two limiting sliders 430 are slidably connected in the limiting chutes 110 and can slide up and down relative to the probe body 100. One of the limiting sliders 430 is located above the other limiting slider 430. One end of the tension spring 420 is fixedly connected to one of the limiting sliders 430, and the other end of the tension spring 420 is fixedly connected to the other limiting slider 430. Specifically, the outer contour shapes of the cross-sections of the limiting chutes 110 and the limiting sliders 430 are both T-shaped, so as to prevent the limiting sliders 430 from disengaging from the limiting chutes 110. Of course, the limiting chutes 110 and the limiting sliders 430 can also be slidably connected in other existing ways, which are not limited herein. During use, the tension spring 420 drives the upper limiting slider 430 to slide downward and the lower limiting slider 430 to slide upward, so that the two connecting rods 440 move closer, and further keep a larger distance between the brush head 410 and the probe body 100 to adapt to a drill hole with a larger diameter. When the diameter of the drill hole is smaller, the brush head 410 is squeezed to make the upper limiting slider 430 slide upward and the lower limiting slider 430 slide downward, so that the two connecting rods 440 open, and further reduce the distance between the brush head 410 and the probe body 100 to adapt to a drill hole with a smaller diameter.

[0039] It should be noted that in some other embodiments, the brush head of the cleaning component can be replaced with a scraper, or the cleaning component can be replaced with a nozzle for connecting an external air source, which is not limited herein.

[0040] It should be noted that in some of these embodiments, a fishing mechanism for fishing the probe body 100 is further included. When the probe body 100 is severely stuck in the drill hole, the probe body 100 in the drill hole can be fished by the fishing mechanism, so as to facilitate the removal of the probe body 100 from the drill hole.

[0041] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 6In some embodiments, a first support arm 500 is provided between the two first rollers 200, and a first strip-shaped through hole 120 is provided on the upper portion of the probe body 100 corresponding to the first support arm 500 and passing through the probe body 100 horizontally. The length direction of the first strip-shaped through hole 120 is consistent with the length direction of the probe body 100, the first support arm 500 is passed through the first strip-shaped through hole 120, the middle portion of the first support arm 500 is rotatably connected to the probe body 100, and the two first rollers 200 are respectively provided on the first support arm 500. 00 at both ends so that the two first rollers 200 can swing up and down relative to the probe body 100, a second support arm 600 is provided between the two second rollers 300, and the lower part of the probe body 100 is provided with a second strip through hole 130 that passes through the probe body 100 horizontally corresponding to the second support arm 600. The length direction of the second strip through hole 130 is consistent with the length direction of the probe body 100. The second support arm 600 is inserted into the second strip through hole 130, and the middle part of the second support arm 600 is rotatably connected to the probe body 100. , the two second rollers 300 are respectively arranged at both ends of the second support arm 600, so that the two second rollers 300 can swing up and down relative to the probe body 100.

The lower end of the pull rope 700 is fixedly connected to one end of the second support arm 600 on the same side, that is, One end of the pull rope 700 connected to the second support arm 600 and the end of the pull rope 700 passing through the first support arm 500 are located on the same side of the probe body 100, and the limiting portion 710 is fixedly provided on the pull rope 700 and is located below the first support arm 500. Specifically, when the part of the pull rope 700 located between the first support arm 500 and the second support arm 600 is straightened, the limiting portion 710 abuts against the first support arm 500, so that when the pull rope 700 is pulled upward, it can drive the first support arm 500 and the second support arm 600 to swing synchronously. Among them, since the first support arm 500 and the second support arm 600 both have a higher end and a lower end, and the higher end of the first support arm 500 and the higher end of the second support arm 600 are located on the same side of the probe body 100 (a well-known technology in this field), it is necessary to pass a pull rope 700 through the higher end of the first support arm 500 and connect the pull rope 700 to the higher end of the second support arm 600. When in use, the pull rope 700 is pulled upward to make the first support arm 500 and the second support arm 600 swing synchronously, thereby driving the first roller 200 and the second roller 300 to move closer to the probe body 100 at the same time, so as to facilitate the removal of the probe body 100 from the drill hole. Its structure is simple and easy to operate.

[0042] It should be noted that in some other embodiments, the drawstring and the limiting part can be replaced with a fishing structure independent of the probe body in the prior art, which is not limited herein.
