Description

Technical Field

[0001] The present application relates to the field of landslide displacement monitoring equipment, and in particular to a landslide deep displacement monitoring equipment. Background Art

[0002] During the landslide construction process, in order to ensure the safety of the landslide, it is necessary to monitor the deep displacement of the landslide. The deep displacement of the landslide needs to be monitored by inclinometer tubes and displacement monitoring equipment. There are several grooves (generally four) inside the monitoring tube, which extend to both ends along the length of the monitoring tube. The monitoring tube needs to be buried in the soil before the landslide construction, and at least one pair of grooves of the monitoring tube needs to be set perpendicular to the landslide treatment line. Two pairs of guide wheels are respectively rotated at both ends of the displacement monitoring device, and both pairs of guide wheels are rollingly matched with the grooves. When performing deep displacement detection of the landslide, align the guide wheel and slide it into the groove, and then lower the displacement monitoring device along the groove to the specified height in the monitoring tube to measure the specified height.

[0003] In the existing related technology, the displacement monitoring device includes a cable joint, a monitoring joint and an O-ring. The cable joint is rotatably matched with a cable, and the monitoring joint is provided with a pin corresponding to the cable. The cable joint and the monitoring joint are threadedly matched, and the O-ring is provided between the cable joint and the monitoring joint, so that the cable can be stably electrically connected to the monitoring pin by rotating the cable joint, and the cable joint and the monitoring joint are sealed by squeezing the O-ring, so that the connection between the pin and the cable is not easy to leak water.

[0004] Regarding the above-mentioned related technologies, after long-term use at the construction site, there is still a problem of water seepage in the cable joints and monitoring joints, which makes the connection between the cable and the pin unstable, affects the transmission of data signals, and reduces the accuracy of deep displacement monitoring of landslides. Summary of the invention

[0005] In order to make the layer displacement monitoring device less susceptible to water seepage, thereby ensuring the accuracy of landslide deep displacement monitoring, the present application provides a landslide deep displacement monitoring device.

[0006] The present application provides a landslide deep displacement monitoring device that adopts the following technical solution:

[0007] A landslide deep displacement monitoring device comprises a cable joint, a monitoring joint and an elastic seal, wherein the cable joint is detachably mounted on the monitoring joint, and the elastic seal is located between the cable joint and the monitoring joint;

[0008] The elastic sealing member comprises a horizontal portion and a vertical portion, wherein the vertical portion is connected to the horizontal portion, and the vertical portion and the horizontal portion are arranged in an "L" shape;

[0009] When the cable joint is installed on the monitoring joint, the cable joint and the monitoring joint are tightly matched on the horizontal part along the first direction, and the cable joint and the monitoring joint are tightly matched on the vertical part along the second direction;

[0010] The angle between the first direction and the second direction is an acute angle, a right angle or an obtuse angle.

[0011] By adopting the above technical solution, the vertical part and the horizontal part seal the gap between the cable joint and the monitoring joint. Compared with the O-ring, the water penetration path is extended, making the deep displacement monitoring equipment less prone to water seepage, thereby ensuring the accuracy of deep displacement monitoring of landslides.

[0012] Optionally, the vertical portion is provided with an extrusion slope, and when the cable connector is installed on the monitoring connector, the cable connector is tightly fitted on the extrusion slope, and the cable connector and the monitoring connector are tightly fitted on the vertical portion along the second direction.

[0013] By adopting the above technical solution, the cable joint generates a component force along the first direction by extruding the inclined surface, and the structure is simple and compact, and easy to maintain.

[0014] Optionally, the cable connector is threadably coupled to the monitoring connector.

[0015] By adopting the above technical solution, the connection relationship between the cable joint and the monitoring joint is simple, and the threaded structure itself has relatively good water sealing performance.

[0016] Optionally, the cable connector is provided with a rotation plane, and the rotation plane is located on the outer circumferential surface of the cable connector.

[0017] By adopting the above technical solution, it is convenient for monitoring personnel to use tools to act on the rotating plane, thereby driving the cable connector to rotate.

[0018] Optionally, the material of the vertical portion is rubber or silicone, and the material of the horizontal portion is rubber or silicone.

[0019] By adopting the above technical solution, the vertical part and the horizontal part have good elasticity.

[0020] Optionally, the vertical portion is integrally connected to the horizontal portion.

[0021] By adopting the above technical solution, the difficulty of molding the elastic sealing component is reduced.

[0022] Optionally, the monitoring joint is provided with a sealing protrusion, and the vertical portion is tightly fitted against the sealing protrusion.

[0023] By adopting the above technical solution, the sealing protrusion extends the water penetration path, making the layer displacement monitoring equipment less likely to be infiltrated by water, thereby ensuring the accuracy of deep displacement monitoring of the landslide.

[0024] Optionally, the vertical portion is provided with a sealing groove, and the inner wall of the sealing groove is tightly fitted with the sealing protrusion.

[0025] By adopting the above technical solution, the sealing groove and the sealing protrusion are adapted to each other, which is conducive to ensuring the connection stability between the vertical part and the monitoring joint, thereby reducing the occurrence of the vertical part falling off from the detection joint.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The vertical part and the horizontal part seal the gap between the cable joint and the monitoring joint. Compared with the O-ring, it prolongs the water penetration path, making the deep displacement monitoring equipment less likely to seep water, thereby ensuring the accuracy of the deep displacement monitoring of the landslide;

[0028] 2. The cable joint generates a component force along the first direction by extruding the inclined surface, and the structure is simple and compact, and easy to maintain;

[0029] 3. The sealing groove and the sealing protrusion are adapted to ensure the connection stability between the vertical part and the monitoring joint, thereby reducing the occurrence of the vertical part falling off from the monitoring joint. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] Embodiment 1:

[0037] Example 1 of the present application discloses a deep displacement monitoring device based on landslide. Figure 1 The landslide deep displacement monitoring device comprises a cable joint 1, a monitoring joint 2 and an elastic seal 3. The cable joint 1 and the monitoring joint 2 are both arranged in a nearly cylindrical shape.

[0038] Reference Figure 1 The cable connector 1 is provided with a rotation hole 101, which is used to rotate the cable connector 1 to match the cable of the deep displacement monitoring device (not shown in the figure). The monitoring connector 2 is fixedly connected with a pin 21, which is used to electrically connect the cable to the probe of the deep displacement monitoring device (not shown in the figure). When performing deep displacement monitoring, the cable needs to be plugged into the pin 21 to facilitate the transmission of data and signals.

[0039] Reference Figure 1 and Figure 2 The inner circumference of the cable joint 1 and the outer circumference of the monitoring joint 2 are threadedly matched, so that the monitoring personnel can rotate the cable joint 1 to firmly connect the cable joint 1 to the monitoring joint 2. The cable joint 1 is provided with six rotation planes 201, which are all located on the outer circumference of the cable joint 1, and the six rotation planes 201 are distributed in a hexagonal shape, so that the monitoring personnel can use tools, such as a wrench, to act on the rotation planes 201, thereby driving the cable joint 1 to rotate a sufficient number of times.

[0040] Reference Figure 1 The elastic seal 3 is elastic and is located between the cable joint 1 and the monitoring joint 2. The elastic seal 3 is sleeved on the pin 21 so that the elastic seal 3 can be squeezed by the cable joint 1 and the monitoring joint 2, and the gap between the cable joint 1 and the monitoring joint 2 is blocked by the deformation of the elastic seal 3, so that water is not easy to penetrate into the connection between the cable and the pin 21.

[0041] Specifically, the elastic seal 3 includes a horizontal portion 31 and a vertical portion 32. The vertical portion 32 is integrally connected to the horizontal portion 31, and the vertical portion 32 and the horizontal portion 31 are arranged in an "L" shape. The material of the vertical portion 32 is selected to be rubber or silicone, and the material of the horizontal portion 31 can also be selected to be rubber or silicone. In Example 1 of the present application, the materials of the vertical portion 32 and the horizontal portion 31 are both selected to be silicone. The vertical portion 32 is provided with an extrusion bevel 321, and the extrusion bevel 321 is located on the outer peripheral surface of the vertical portion 32, that is, the surface of the vertical portion 32 away from the plug pin 21, and the extrusion bevel 321 is closed from beginning to end and arranged in a ring shape. The cross-section of the vertical portion 32 is arranged in a trapezoidal shape under the action of the extrusion bevel 321, and the end of the vertical portion 32 with a smaller outer diameter is arranged toward the cable.

[0042] When the cable joint 1 is installed on the monitoring joint 2, the inner circumference of the cable joint 1 and the outer circumference of the monitoring joint 2 are tightly fitted to the horizontal part 31 along the first direction, and the inner circumference of the cable joint 1 is tightly fitted to the extrusion inclined surface 321, and the inner circumference of the cable joint 1 and the outer circumference of the monitoring joint 2 are tightly fitted to the vertical part 32 along the second direction. The angle between the first direction and the second direction is an acute angle, a right angle or an obtuse angle, that is, the first direction and the second direction are not arranged in the same direction, so as to press the elastic seal 3 in two directions respectively and extend the water penetration path to achieve the effect of improving the water sealing. In Example 1 of the present application, the first direction refers to: the length direction of the cable joint 1; and the second direction refers to: the radial direction of the cable joint 1; and the angle between the first direction and the second direction is a right angle.

[0043] The implementation principle of the landslide deep displacement monitoring device according to the first embodiment of the present application is as follows: after the cable is plugged into and electrically connected to the pin 21 , the cable connector 1 is rotated by the rotating plane 201 so that the cable connector 1 is threadedly matched with the monitoring connector 2 .

[0044] During the rotation of the cable joint 1, the inner circumference of the cable joint 1 gradually approaches the extrusion slope 321 and finally fits tightly against the extrusion slope 321. After the inner circumference of the cable joint 1 fits tightly against the extrusion slope 321, the cable joint 1 generates a force component in two directions, namely, along the first direction and along the second direction, through the extrusion slope 321, and fits tightly against the horizontal part 31 through the force component in the first direction, and fits tightly against the vertical part 32 through the force component in the second direction, thereby, on the one hand, extending the water penetration path through the horizontal part 31 and the vertical part 32 distributed in an "L" shape, and on the other hand, reducing the generation of the penetration path by fitting tightly against the elastic seal 3 from two directions, making it difficult for the deep displacement monitoring equipment to leak water, thereby ensuring the accuracy of the deep displacement monitoring of the landslide.

[0045] Embodiment 2:

[0046] Embodiment 2 of the present application discloses a landslide deep displacement monitoring device, which includes all the technical features of Embodiment 1 and also includes the following technical features:

[0047] Reference Figure 3 and Figure 4 The monitoring joint 2 is provided with three sealing protrusions 22, which are all arranged in a ring shape with the ends closed, and the three sealing protrusions 22 are distributed along the first direction, and the cross-sections of the three sealing protrusions 22 are all arranged in a trapezoidal shape. The vertical portion 32 is provided with three sealing grooves 322, and the inner walls of the three sealing grooves 322 are respectively tightly fitted with the three sealing protrusions 22, so as to ensure the connection stability between the elastic seal 3 and the monitoring joint 2, and by further extending the water penetration path, the deep displacement monitoring device is not easy to leak water.

[0048] The implementation principle of Example 2 of the present application, a device for monitoring deep displacement of landslides, is similar to that of Example 1 and will not be elaborated on herein.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
