[0002] According to the instability characteristics of slope deformation evolution, landslides can be divided into sudden change type landslides and gradual creep type landslides. Among them, gradual creep type landslides account for a large proportion of slope instability. The instability of loose soil slopes, accumulation layer slopes, weathered rock slopes and various soft rock slopes all belong to gradual creep type slopes. Therefore, the monitoring and early warning of gradual creep type landslides are particularly important.

[0003] For example, patent number CN216927779U discloses a multi-sensor slope monitoring and early warning device, including a main support column and a number of auxiliary support rods: the auxiliary support rods are arranged in a uniform array along the circumference around the periphery of the main support column, and reinforcing ribs are arranged between each auxiliary support rod and the main support column. The main support column is provided with an energy collection and rainfall monitoring device, a communication module, a vibration sensor and a soil moisture sensor, and the auxiliary support rod is provided with a tilt sensor and a pressure sensor.

[0033] See also Figure 1-7 The utility model provides a technical solution: a slope displacement monitoring and early warning device, comprising a first vertical rod 2 arranged at the bottom end of the slope 1 and a second vertical rod 3 arranged at the middle end of the slope 1, one side of the first vertical rod 2 is movably connected with a connecting tube 4, the closed end of the connecting tube 4 is connected to the first vertical rod 2, and the open end extends in the direction of the second vertical rod 3, one side of the second vertical rod 3 is movably connected with a connecting rod 13, one end of the connecting rod 13 is connected to the second vertical rod 3, and the other end is inserted into the connecting tube 4 and is slidably connected to the connecting tube 4;

[0034] An alarm component is provided at one end of the connecting tube 4 close to the second vertical rod 3 , and the alarm component is used to feedback the length of the connecting rod 13 inserted into the connecting tube 4 .

[0035] In this solution, after the connecting tube 4 is slidably connected to the connecting rod 13 , it is vertically parallel to the surface of the slope, so that the connecting rod 13 can slide in the connecting tube 4 when the second vertical rod 3 moves with the slope 1 .

[0036] During use, the first vertical rod 2 and the second vertical rod 3 are respectively fixed at the bottom and middle ends of the slope 1, and the connecting rod 13 on the second vertical rod 3 is inserted into the open end of the connecting tube 4 on the first vertical rod 2. When the slope 1 is stable, the connecting rod 13 stops sliding in the connecting tube 4, and the warning component is in an untriggered state. When the slope 1 gradually loses stability and collapses, the second vertical rod 3 will displace and slide along with the soil layer on the slope 1, and the connecting rod 13 will slide in the connecting tube 4 along with the displacement of the second vertical rod 3. When the connecting rod 13 slides to a certain length in the connecting tube 4, the warning component is triggered, giving an early warning reminder to the staff during the construction process or passing vehicles and pedestrians after the project is completed.

[0037] Through the sliding length of the connecting rod 13 in the connecting tube 4 and in cooperation with the warning component arranged at one end of the connecting tube 4 close to the second vertical rod 3, when the slope 1 becomes unstable and collapses, the warning component is triggered after the connecting rod 13 slides to a certain length in the connecting tube 4, making it convenient for the staff to observe and understand the displacement of the slope.

[0038] In this embodiment: the warning component includes a movable rod 6, a plurality of connecting holes 5 are opened on the connecting tube 4, and the plurality of connecting holes 5 are arranged along the length direction of the connecting tube 4. The movable rod 6 is movably matched in the connecting hole 5, and the bottom end of the movable rod 6 is located in the connecting tube 4. The top end of the movable rod 6 is provided with a limit block 7 located above the connecting hole 5;

[0039] Two outwardly protruding fixed blocks 8 are fixedly connected to the outer wall of the connecting tube 4, a plurality of connecting holes 5 are located between the two fixed blocks 8, a connecting plate 9 is arranged above the plurality of connecting holes 5, both ends of the connecting plate 9 are respectively connected to the two fixed blocks 8, a plurality of warning lights 10 corresponding to the plurality of movable rods 6 are arranged on the top surface of the connecting plate 9, a control key 11 connected in series with the warning light 10 is arranged on the bottom surface of the connecting plate 9, and a plurality of the warning lights 10 are arranged in parallel.

[0040] In this solution, a plurality of warning lights 10 correspond to different levels of instability and collapse of the slope 1, and the plurality of warning lights 10 correspond to a plurality of connecting holes 5 arranged along the length direction of the connecting tube 4, and the connecting rod 13 is used to sequentially trigger the warning lights 10 of different levels from low to high in the sliding length of the connecting tube 4 for early warning; the power source required by the warning lights 10 can be an external power source connected by a wire, or a battery built into the fixing block 8 (both power supply connections can be realized by existing technologies);

[0041] The working circuit of the warning light 10 is as follows Figure 7 As shown, when the control key 11 contacts L1, it is in the open state, and the warning light 10 opposite thereto is turned off; when the control key 11 contacts L2, it is in the closed state, and the warning light 10 is in the open state.

[0042] During use, when the slope 1 gradually becomes unstable and collapses, the second vertical rod 3 will displace and slide together with the soil layer on the slope 1, and the connecting rod 13 will slide in the connecting tube 4 along with the displacement of the second vertical rod 3. When the connecting rod 13 slides to a certain length in the connecting tube 4, it will contact the movable rod 6 located in the connecting tube 4 and push the movable rod 6 out of the connecting hole 5, so that the limit block 7 at the top of the movable rod 6 moves upward and contacts the control key 11, so that the control key 11 contacts L2 in a closed state, and the warning light 10 emits light to warn the relevant staff, and the staff will take corresponding measures after receiving the warning.

[0043] Among them, the model of the warning light is AD56-22DS.

[0044] In this embodiment: a baffle plate 17 is arranged on the bottom surface of the connecting plate 9 , one end of the baffle plate 17 is connected to the connecting plate 9 , and the other end extends downward, and four baffle plates 17 are arranged around the connecting plate 9 .

[0045] When in use, the baffle plate 17 can shield the control key 11, and can prevent the problem of rainwater contacting the control key 11 and causing a short circuit when it rains.

[0046] In this embodiment, the bottom end of the movable rod 6 and the tail end of the connecting rod 13 are both semicircular.

[0047] When the connecting rod 13 slides in the connecting tube 4 and contacts the bottom end of the movable rod 6, since the bottom end of the movable rod 6 and the tail end of the connecting rod 13 are both semicircular, the connecting rod 13 lifts the movable rod 6 during continuous movement, so that the limit block 7 at the top of the movable rod 6 contacts the control key 11, turning on the warning light 10.

[0051] In this solution, the shape of the protective net 16 can be a semicircular arc, a cylindrical shape, or a block shape.

[0052] By arranging a protection net 16 at the bottom end of the second vertical rod 3, the contact area between the second vertical rod 3 and the slope 1 can be increased, so that the protection net 16 is filled with soil, which can reduce the probability of the second vertical rod 3 loosening and collapsing when the slope 1 gradually loses stability and collapses.

[0053] In this embodiment: the first vertical rod 2 and the second vertical rod 3 are both provided with connecting pieces 15 at their upper ends, and are detachably connected to the connecting tube 4 and the connecting rod 13 via the two connecting pieces 15 .

[0054] When a problem occurs between the first vertical rod 2 and the connecting tube 4 or between the second vertical rod 3 and the connecting rod 13, they can be disassembled and replaced in time through the connecting piece 15, thereby reducing the cost.

[0055] In this embodiment: the connecting member 15 includes an articulated seat 151, a sleeve 152 and an insertion rod 153, one side of the articulated seat 151 is fixedly connected to one side of the first vertical rod 2 and the second vertical rod 3, the sleeve 152 is located on the inner side of the articulated seat 151, and the inner wall of the sleeve 152 is provided with an internal thread, the connecting tube 4 and one end of the connecting rod 13 are both provided with a through hole 154, the tail end of the insertion rod 153 is provided with an external thread, the tail end of the insertion rod 153 passes through one side of the connecting seat and passes through the through hole 154 to be connected with the internal thread.

[0056] When the first vertical rod 2 and the second vertical rod 3 are respectively fixed at corresponding positions on the slope 1, one end of the connecting tube 4 with the through hole 154 is placed on the inner side of the hinge seat 151 of the first vertical rod 2, and the plug rod 153 passes through the through hole 154 on the connecting tube 4 and is threadedly connected to the sleeve 152. The connecting tube 4 can rotate on the hinge seat 151 with the plug rod 153 as the axis. At the same time, one end of the connecting rod 13 is placed in the connecting tube 4, and the other end with the hole is placed on the inner side of the hinge seat 151 of the second vertical rod 3, and the plug rod 153 passes through the through hole 154 on the connecting rod 13 and is threadedly connected to the sleeve 152, thereby achieving the purpose of easy disassembly, replacement or storage.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
