DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 , 2As shown, a measuring device for rock and soil geological exploration depth includes: a chassis 1, a positioning hole 11 is provided in the middle of the chassis 1; a slide rail mechanism 2, the slide rail mechanism 2 is arranged on the top of the chassis 1; a driving motor 3, the driving motor 3 is slidably connected to the slide rail mechanism 2, and a counting plate 31 is fixedly connected to the side wall of the driving motor 3, and the counting plate 31 passes through the slide rail mechanism 2; a counting mechanism 4, the counting mechanism 4 includes a counter 41 and a display board 42, and the counting board 31 can press the counter 41; a straightening frame 5, the straightening frame 5 is arranged just above the positioning hole 11; a winding shaft 6, the winding shaft 6 is arranged above the straightening frame 5, a measuring line 61 is wound on the winding shaft 6, and a passive gear 62 is provided on the side wall of the winding shaft 6; a depth probe 7, the depth probe 7 is arranged at the bottom of the measuring line 61, and the depth probe 7 includes a rotating wing 71; a driving gear 8, the driving gear 8 is detachably connected to the driving motor 3, and the driving gear 8 can mesh with the passive gear 62.

[0028] When conducting geotechnical survey, the length of the drill rods 9 used is the same. The depth of the borehole can be roughly estimated by counting the number of drill rods 9 , and the depth of the geotechnical survey borehole can be accurately obtained by placing the measuring line 61 .

[0029] like Figure 4 As shown, the slide rail mechanism 2 includes two first slides 21, a second slide 22, a threaded rod 23 and a second motor 24. The first slide 21 and the second slide 22 are both rectangular rods with a slot in the middle. The first slide 21 is arranged on both sides of the chassis 1, and the second slide 22 is arranged between the two first slides 21. The heights of the first slide 21 and the second slide 22 are both greater than the length of a single drill rod 9. The second motor 24 is fixedly connected to the bottom of the second slide 22, and the output end of the second motor 24 faces upward. The threaded rod 23 is fixedly connected to the output end of the second motor 24. The second motor 24 drives the threaded rod 23 to rotate, and the top of the threaded rod 23 is rotatably connected to the second slide 22.

[0030] Two support rods 32 are also fixedly connected to the side wall of the driving motor 3. The two support rods 32 extend laterally into the first slideway 21. The two support rods 32 are located on both sides of the driving motor 3. The support rods 32 prevent the driving motor 3 from shaking, so that the driving motor 3 can move up and down stably.

[0031] The counting plate 31 passes through the second slideway 22, and the threaded rod 23 is screwed to the counting plate 31. When the second motor 24 drives the threaded rod 23 to rotate, the threaded rod 23 drives the counting plate 31 to move up and down. Since the front end of the counting plate 31 is fixedly connected to the driving motor 3, when the counting plate 31 moves up and down, the driving motor 3 moves up and down together, and the output end of the driving motor 3 is detachably connected to the drill rod 9.

[0032] The counter 41 is provided with a groove, the width of which is greater than the width of the rear end of the counting board 31, and the counting board 31 can enter the groove. A button 411 is provided in the groove, and the counting board 31 can press the button 411 after entering the groove. When the counting board 31 is lifted, the button 411 automatically resets. The counter 41 is connected to the display board 42 by signal, and the display board 42 displays the number of times the button 411 is pressed. When the driving motor 3 drives the drill rod 9 to reach the counter 41, the counting board 31 presses the button 411, and then the drill rod 9 is separated from the driving motor 3, and the driving motor 3 is moved up to connect another drill rod 9. The data displayed on the display board 42 is the number of drill rods 9 driven into the exploration borehole. The length of the drill rod 9 is multiplied by the number on the counting board 31 to obtain the approximate drilling depth.

[0033] There is a circular hole in the middle of the straightening frame 5, and the diameter of the circular hole is larger than the outer diameter of the drill rod 9. The drill rod 9 enters the formation through the circular hole and the positioning hole 11. The straightening frame 5 prevents the drill rod 9 from being displaced. The top surface of the straightening frame 5 and the bottom surface of the groove are at the same height. When the output end of the drive motor 3 contacts the straightening frame 5, the straightening frame 5 limits the drive motor 3 from continuing to move downward, and at the same time, the counting board 31 just presses the button 411 to avoid the situation where the counting board 31 crushes the counter 41.

[0034] There are pillars 12 on both sides of the straightening frame 5, and the two sides of the winding shaft 6 are rotatably connected to the pillars 12. When the drill rod 9 is surveyed, the winding shaft 6 is rotated to the side so that the winding shaft 6 does not affect the lowering and extraction of the drill rod 9. When the survey drilling is completed and all the drill rods 9 are taken out, the winding shaft 6 is rotated to the top of the straightening frame 5, and the depth probe 7 is passed through the positioning hole 11 into the survey hole.

[0035] Insert the top of the driving gear 8 into the output end of the driving motor 3 through a pin, connect the driving gear 8 to the driving motor 3, and then lower the driving motor 3 to make the driving gear 8 and the passive gear 62 mesh. The driving motor 3 drives the driving gear 8 to rotate, and the driving gear 8 drives the passive gear 62 and the winding shaft 6 to rotate, so as to accelerate the placement of the measuring line 61 in the exploration hole, eliminate the need for manual reeling and unreeling, and improve the depth measurement speed.

[0036] like Figure 3 As shown, the measuring line 61 has a built-in transmission conductor, the outer wall of the measuring line 61 has a scale ruler, the bottom of the depth probe 7 is provided with a third motor 72, and the rotating wing 71 is fixedly connected to the output end of the third motor 72. When the depth probe 7 is lowered, the rotating wing 71 rotates to clear the soil blocks or other protrusions in the hole that block the depth probe 7, so that the depth probe 7 can be lowered normally. When the surveyor finds that the measuring line 61 is no longer tight, it indicates that the depth probe 7 has reached the bottom of the hole. At this time, the accurate hole depth data can be obtained by reading the measuring line 61.

[0037] Rough survey depth data can be obtained through the counter 41 and the display panel 42, and accurate survey depth data can be obtained through the depth sounding probe 7. Surveyors can freely choose the required data type according to their own survey purposes.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
