[0002] At present, more and more mines are abandoned due to the end of mining activities.

DETAILED DESCRIPTION

[0042] See also Figure 1 In an embodiment of the present invention, a slope anti-seepage detection device includes:

[0043] There are two positioning posts 2, one of which is vertically inserted at the top of the slope, and the other is horizontally inserted at the bottom of the slope.

[0044] A main connecting frame 1 is connected between the positioning columns and is erected parallel to the slope surface;

[0045] Seepage measurement components 4 are arranged in parallel, with one end of each seepage measurement component 4 vertically inserted into the middle rock layer of the slope edge, for real-time detection of seepage conditions in the sedimentary layer on the slope edge;

[0046] A displacement guide seat 3 is provided corresponding to each of the seepage measurement components 4. The displacement guide seat 3 is slidably provided on the main connecting frame 1. The other end of the seepage measurement component 4 is slidably connected to the displacement guide seat 3; and

[0047] The lateral measurement component 5 is arranged on the left and right sides of each of the seepage measurement components 4, and is used to perform real-time detection of the seepage conditions of the slope surface sediment layer around the seepage measurement component 4. On the one hand, the lateral measurement component can be used as independent detection data to truly reflect the overall seepage conditions of the slope surface when seepage occurs in the slope surface sediment layer; on the other hand, the lateral measurement component can be used as auxiliary data support for the seepage detection of the slope surface sediment layer in the seepage measurement component, and is used to more accurately reflect the different seepage degrees of each slope surface point on the slope.

[0048] In this embodiment, the seepage measurement component 4 includes:

[0049] The upper shaft rod 41 and the lower shaft rod 42 are constructed as support rod structures of the same specifications. The upper shaft rod 41 and the lower shaft rod 42 are rotatably connected to each other, and the lower shaft rod 42 is vertically inserted into the inner layer of the rock mass and partially extends into the slope sediment layer. The upper shaft rod 41 is vertically inserted into the slope sediment layer.

[0050] A plurality of expansion racks 46 are arranged in a circular array, and each expansion rack 46 is rotatably mounted on an end of the lower shaft 42 away from the upper shaft 41;

[0051] An inner air pressure tube 43 is coaxially fixed inside the lower shaft 42;

[0052] A piston push rod 44 is relatively slidably disposed in the inner air pressure tube 43, a limiting ring is provided in the inner air pressure tube 43, and a return spring 45 is connected between the piston push rod 44 and the limiting ring; and

[0053] The side link 47 is arranged corresponding to each of the expansion frames 46. One end of the side link 47 is hinged on the piston push rod 44, and the other end of the side link 47 is connected to the expansion frame 46. The expansion frame can vertically fix the lower shaft rod in the inner layer of the rock mass on the slope to prevent the lower shaft rod from being displaced synchronously when seepage occurs.

[0054] As a preferred embodiment, the connection point between the upper shaft rod 41 and the lower shaft rod 42 is located at three-quarters of the depth of the slope sediment layer, where the given depth is suitable for seepage detection of most slope sediment layers, especially for dealing with harsh environmental conditions such as rainfall infiltration and slope runoff.

[0055] In this embodiment, the lateral measurement assembly 5 is composed of an upper frame and a lower frame, wherein a positioning guide frame 51 is obliquely inserted into the slope sediment layer, and one end of the upper frame and the lower frame are connected to the positioning guide frame 51, and the upper frame and the lower frame have the same composition structure and jointly include:

[0056] A fixed shaft frame 52 is fixed parallel to one side of the seepage measurement assembly 4, and an outer sleeve is slidably sleeved on the fixed shaft frame 52;

[0057] A support spring 54 is sleeved outside the fixed shaft frame 52 and is in contact with the outer sleeve;

[0058] A pressure sensor 53 is provided on one end of the fixed shaft frame 52 away from the outer sleeve, and the other end of the support spring 54 is in contact with the pressure sensor 53;

[0059] An outer support rod 55, hinged to the outer sleeve; and

[0060] The measuring rod 56 is vertically inserted into the slope sediment layer and connected to the positioning guide frame 51 . One end of the measuring rod 56 is hinged to the outer support rod 55 .

[0061] In this embodiment, the outer support rod 55 in the upper frame and the measuring rod 56 form an obtuse-angled outward support frame, while the outer support rod 55 in the lower frame and the measuring rod 56 form an acute-angled inward support frame, and the length of the measuring rod 56 in the upper frame is smaller than the length of the measuring rod 56 in the lower frame. That is to say, in the slope seepage prevention detection, when seepage occurs at the slope, the measuring rod in the upper frame and the measuring rod in the lower frame both deflect clockwise. At this time, the outer set is driven by the outer support rod to perform relative displacement, and the support spring transmits the elastic force to the pressure sensor in a compressed state, and the pressure sensor performs real-time pressure detection, thereby reflecting the degree of seepage according to the pressure size.

[0062] In this embodiment, a steering seat 31 is fixed on the displacement guide seat 3, and a side frame sleeve 32 is provided in the steering seat 31 so as to be relatively deflectable. One end of the seepage measurement component 4 is slidably connected to the side frame sleeve 32 and is rotatably connected to the steering seat 31 by the side frame sleeve 32; a displacement time measuring device 6 is also provided in the displacement guide seat 3, and the displacement time measuring device 6 can accurately measure the relative displacement point and displacement dwell period of the displacement guide seat 3.

[0063] As a preferred embodiment, the displacement timing measuring device 6 includes:

[0064] Mounting frame 61;

[0065] A fixed body 62 is embedded and fixed on one side of the mounting frame 61;

[0066] The top shaft 63 is vertically arranged in the fixed body 62 so as to be relatively slidable, and the lower end of the top shaft 63 is in contact with the main connecting frame 1 through a rotatable guide wheel;

[0067] The inner spring 64 is vertically symmetrically arranged in the fixed body 62 and connected to the top shaft 63;

[0068] Contact members are symmetrically arranged on both sides of the top shaft 63; and

[0069] The induction gasket 65 is annularly embedded in the fixed body 62. The induction gasket 65 can transmit an electrical signal to an external data console (not shown in the figure) when in contact with a contact member.

[0070] In this embodiment, it also includes:

[0071] An inner link rod is rotatably arranged on one side of the fixed body 62. A supporting spring 66 is provided in the mounting frame 61. One end of the supporting spring 66 is connected to the inner link rod.

[0072] The contact head is fixed below one end of the inner connecting rod, and a plurality of inner grooves are arranged on the main connecting frame 1. A spring plate is embedded in each of the inner grooves through a connecting spring 67, and the contact head and the top shaft 63 are alternately in contact with the spring plate. That is to say, when the top shaft in the mounting frame moves to the inner groove and contacts with the spring plate, the sensing gasket can contact the contact piece accordingly and output the electrical signal to the outside, and the contact head generates a first pressure due to the elastic force of the supporting spring; and when the top shaft moves outside the inner groove, the sensing gasket and the contact piece are in a disengaged state, and the contact head generates a second pressure due to the elastic force of the supporting spring. During the lateral displacement of the mounting frame, the contact head can determine the displacement distance of the mounting frame based on the first pressure and the second pressure, and the top shaft can measure the retention time based on the displacement distance.

[0073] Specifically, the positioning columns are preferentially inserted vertically at the top and bottom of the slope, and the positioning guides can be tilted and inserted into the slope sediment layer. At this time, each seepage measurement component, the upper frame and the lower frame are evenly and vertically inserted into the slope sediment layer, and one end of the upper frame and the lower frame are connected to the positioning guides. In the slope anti-seepage detection, the upper shaft can be directionally deflected accordingly. At this time, the displacement time measurement device can perform real-time detection of the displacement distance and the retention period, and transmit data to the outside. At the same time, the pressure sensors in the upper frame and the lower frame will feedback the surrounding seepage degree, thereby improving the detection accuracy and achieving real-time detection effect.

[0074] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
