[0037] A limit assembly for limiting the rotation of the rotating shaft 2 is arranged inside the mounting bracket 1. The limit assembly that moves upward when subjected to force is used to release the rotation restriction of the rotating shaft 2, and the limit assembly that moves downward when the force is lost is used to limit the rotation of the rotating shaft 2.

[0038] The support mechanism 7 includes a first adjustment component and a second adjustment component; the first adjustment component is used to adjust the height of the support mechanism 7, and the second adjustment component is used to adjust the angle of the support mechanism 7.

[0039] In this embodiment, after the underground drilling is completed, the height of the groundwater level from the ground needs to be measured. First, the water level sensor 6 is connected to one end of the ruler 4, and then the support mechanism 7 is adjusted, and the ruler 4 is placed on the fixed pulley at the top of the support mechanism 7;

[0040] Before the ruler 4 is placed on the fixed pulley, the overall height of the support mechanism 7 is adjusted by the first adjustment component, and the inclination angle of the support mechanism 7 is adjusted by the second adjustment component, so as to better facilitate the water level sensor 6 to fall along the ground drill hole;

[0041] By pressing the limit assembly, the rotation restriction on the rotating shaft 2 is released, and then the handle 5 is turned, and the handle 5 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the turntable 3 to rotate. During the rotation of the turntable 3, the ruler 4 is unwound, and the ruler 4 can move toward the bottom of the drill hole on the ground to measure the water level.

[0042] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the limiting assembly includes: a movable slot 9, a pressing block 10, a compression spring 11, a connecting plate 12, a bar 13, a limiting tooth 14 and a gear 15;

[0043] The movable groove 9 is provided inside the mounting bracket 1, and the pressing block 10, the connecting plate 12 and the strip rod 13 are slidably connected to the inner wall of the movable groove 9 up and down;

[0044] The two connecting plates 12 are fixedly connected to the two sides of the pressing block 10 respectively, and the connecting plates 12 are in a "Z"-shaped structure. The strip rod 13 is fixedly connected to the bottom end of the horizontal plate portion below the strip rod 13;

[0048] In this embodiment, when the ruler 4 is unrolled, an upward squeezing force is applied to the pressing block 10 by hand, and the pressing block 10 moves upward along the movable groove 9 and squeezes the compression spring 11, and the compression spring 11 is compressed;

[0049] At the same time, the pressing block 10 moving upward drives the two connecting plates 12 to move upward, and the two connecting plates 12 moving upward respectively drive the bar 13 at the bottom thereof to move upward, and the bar 13 can drive the limiting tooth 14 to separate from the gear 15, and at this time the gear 15 loses its limiting position;

[0050] The handle 5 can be turned, and the handle 5 drives the turntable 3 to rotate through the rotating shaft 2, and the rotating turntable 3 can unwind the meter ruler 4. Conversely, the reverse handle 5 can realize the rewinding of the meter ruler 4;

[0051] When the water level sensor 6 contacts the groundwater surface, the water level sensor 6 transmits the signal to the terminal through the wire, and the operator can find it. At this time, the force applied to the pressing block 10 is immediately removed. At this time, the compression spring 11 pushes the pressing block 10 to reset. The pressing block 10 drives the limit tooth 14 to reset through the connecting plate 12 and the strip rod 13, and the gear 15 is clamped and limited. Then the scale on the ruler 4 can be read.

[0052] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the support mechanism 7 further includes a rotating ring 701, a fixing sleeve 702 and a lifting column 703, the first adjusting component is used to adjust the overlapping height of the fixing sleeve 702 and the lifting column 703, and the second adjusting component is used to adjust the rotation angle of the rotating ring 701 and the mounting bracket 1;

[0053] The rotating ring 701 is rotatably connected to the outer wall of the mounting bracket 1, the fixing sleeve 702 is fixedly connected to the upper part of the outer wall of the rotating ring 701, and the lifting column 703 is slidably connected to the inner cavity of the fixing sleeve 702;

[0054] The first adjustment assembly includes: a first receiving groove 704, a first return spring 705, a first clamping column 706 and a first clamping groove 707;

[0055] Two rows of fixing sleeves 702 are vertically symmetrically arranged on both sides of the inner cavity of the fixing sleeve 702. There are multiple fixing sleeves 702 in one row, and the multiple fixing sleeves 702 in one row are evenly spaced in the vertical direction.

[0056] Two first receiving grooves 704 are symmetrically arranged at the lower outer side of the lifting column 703, a first return spring 705 is installed on the inner wall of the first receiving groove 704, a first clamping column 706 is connected to one end of the first return spring 705, and a hemispherical end of the first clamping column 706 penetrates the outside of the first receiving groove 704 and docks with the first clamping groove 707, and the first clamping column 706 is axially slidably connected to the inner cavity of the first receiving groove 704;

[0057] The first clamping groove 707 is in a hollow hemispherical structure, and the first clamping groove 707 and the outer wall of the hemispherical end of the first clamping column 706 are connected.

[0058] In this embodiment, when adjusting the overall height of the support mechanism 7, by applying an upward pulling force or a downward pushing force to the lifting column 703, the lifting column 703 can slide up and down along the inner wall of the fixing sleeve 702 under the force;

[0059] When the lifting column 703 slides up and down, the lifting column 703 drives the first clamping column 706 to move up and down. The first clamping column 706 applies a squeezing force to the inner wall of the first clamping groove 707 during the movement. Since the first clamping groove 707 cannot move, the reaction force acts on the hemispherical end of the first clamping column 706. The first clamping column 706 is forced to move toward the inside of the first accommodating groove 704 and applies a squeezing force to the first return spring 705 until the first clamping column 706 is completely separated from the first clamping groove 707.

[0060] When the first clamping column 706 is aligned with another first clamping groove 707, the first return spring 705 is reset, and the first return spring 705 pushes the first clamping column 706 to clamp into the first clamping groove 707 aligned therewith until the height adjustment purpose of the support mechanism 7 is completed.

[0061] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the second adjustment assembly includes: a second clamping groove 708, a second accommodating groove 709, a second return spring 710 and a second clamping column 711;

[0062] Two groups of second clamping grooves 708 are symmetrically distributed on the end surface of the raised portion of the mounting bracket 1. The number of one group of second clamping grooves 708 is multiple, and the multiple second clamping grooves 708 are distributed in the circumferential direction.

[0063] Two second receiving grooves 709 are symmetrically arranged on the end surface of the inner convex part of the rotating ring 701, the second return spring 710 is connected to the inner cavity of the second receiving groove 709, the second clamping column 711 is connected to one end of the second return spring 710, and the hemispherical end of the second clamping column 711 passes through the outside of the second receiving groove 709 and docks with the second clamping groove 708;

[0064] The second clamping groove 708 is in a hollow hemispherical structure, and the second clamping groove 708 is consistent with the outer wall of the hemispherical end of the second clamping column 711 .

[0065] In this embodiment, when adjusting the angle of the support mechanism 7, by applying a thrust in the left and right directions to the fixing sleeve 702, the fixed sleeve 702 under force drives the rotating ring 701 to rotate along the outside of the mounting bracket 1, and the rotating ring 701 drives the second clamping column 711 to rotate;

[0066] The second clamping column 711 exerts a squeezing force on the inner wall of the second clamping groove 708 during the movement. Since the second clamping groove 708 cannot move, the reaction force acts on the hemispherical end of the second clamping column 711. The second clamping column 711 is forced to move toward the inside of the second accommodating groove 709 and exerts a squeezing force on the second return spring 710 until the second clamping column 711 is completely separated from the second clamping groove 708.

[0067] When the second clamping column 711 is aligned with another second clamping groove 708, the second return spring 710 is reset, and the second return spring 710 pushes the second clamping column 711 to clamp into the second clamping groove 708 aligned therewith until the rotation adjustment purpose of the support mechanism 7 is completed.

[0069] In this embodiment, the annular groove body provides a rotation space for the gear 15 to rotate. When the rotating shaft 2 rotates, the gear 15 is driven to rotate in the annular groove, and the bearing can effectively reduce the friction force when the rotating shaft 2 rotates.
