Description

Technical Field

[0001] The invention relates to the technical field of landslide monitoring and early warning, and in particular to a multi-point landslide monitoring and early warning mechanism. Background Art

[0002] Landslide is a natural geological disaster. In order to reduce the losses caused by landslide disasters, it is necessary to set up a monitoring and early warning mechanism. Landslide monitoring and early warning is a comprehensive disaster prevention system built through multi-dimensional sensing technology, data analysis models and emergency response systems. Its core is to capture geological deformation parameters in real time and predict risks in advance. For example, the announcement number CN115394049B is a landslide and debris flow monitoring and early warning device. It includes a lifting frame, and a lifting mechanism is provided on the end wall of the lifting frame. The lifting mechanism can realize the movement of the mechanism to monitor the surface of the mountain to prevent landslides and debris flows from causing damage, and can realize the monitoring of the interior of the mountain, and can monitor the movement of the mountain in advance and issue early warnings; the movement of the mechanism can realize the fixation of the device, and can realize the fixation of the slope, and can use electric push rods for leveling; the movement of the mechanism can realize the lifting of the device to the corresponding position, without the need for manual placement, ensuring a certain degree of safety; it is equipped with an alarm, which can realize the use of the alarm to issue an alarm and early warning, facilitating timely and safe escape protection;

[0003] For example, a small-scale precise monitoring and early warning device for deformation and landslide of mud slopes with announcement number CN218547651U includes a monitoring unit with multiple anchor rod assemblies, and the monitoring unit is electrically connected to a data acquisition and transmission device. When in use, the monitoring unit is anchored on the detection point of the mud slope and connected to the data acquisition and transmission device, and monitoring can be carried out. It is simple to implement, low-cost, and reusable. The specific installation form of the monitoring unit can be comprehensively considered according to the needs of the actual project, including accuracy, reliability, durability, and cost. The installation is stable, providing a technically reliable, methodologically feasible, and economically reasonable technical solution for monitoring and early warning of mud slopes. It can also accurately sense and automatically collect, transmit, solve, and alarm mud slope deformation data in real time, with high measurement accuracy, for use and reference in disaster prevention and mitigation of slopes. However, the above-mentioned monitoring and early warning device still has the following shortcomings during actual use:

[0004] 1. Traditional monitoring and early warning agencies can only conduct single-point monitoring and are unable to conduct multi-point monitoring and early warning of slopes. As a result, they are unable to issue warnings in time before landslides occur, increasing the losses caused by disasters.

[0005] 2. After a landslide occurs, a large amount of sediment is lost, and the monitoring and early warning agencies are unable to block the sediment from the landslide.

[0006] In response to the above problems, it is urgently necessary to carry out innovative designs based on the original monitoring and early warning agencies. Summary of the Invention

[0007] The purpose of the present invention is to provide a multi-point landslide monitoring and early warning mechanism to solve the problem raised in the above background technology that most traditional monitoring and early warning mechanisms can only perform single-point monitoring and cannot perform multi-point monitoring and early warning on the slope, and the monitoring and early warning mechanism does not have the function of blocking the mud and sand of the landslide.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multi-point landslide monitoring and early warning mechanism, comprising a base plate and a first fastener and a second fastener at the corner of the base plate, the second fastener being hollow, and a pull-type alarm being installed on the inner top surface of the second fastener; further comprising: columns symmetrically arranged at both ends of the base plate, a signal transmitter being installed on the top of one of the columns, and a push-type alarm being installed on the top of the other column, and an inclined barrier net being arranged between the two columns; an adjustment mechanism being arranged between the two columns, the adjustment mechanism being used to adjust the angle between the column and the base plate; an auxiliary component being arranged on the side of the column, the auxiliary component being used to assist in preventing mud and sand landslides.

[0009] Preferably, a movable block is provided on the side of the second fastener for rotation, and the two movable blocks have different heights, and a vortex spring is provided at the rotation point of the movable block. At the same time, the second fastener and the first fastener are both slidably connected to the base plate, and the base plate can be connected to the slope through two sets of fasteners.

[0010] Preferably, the inner side of the movable block is fixedly connected to one end of the traction rope, and the other end of the traction rope is fixed to the pull ring, and the pull ring is arranged at the bottom of the pull-type alarm. When the movable block is not pressed by the soil, the resilience of the vortex spring can drive the movable block to unfold.

[0011] Preferably, the baffle net and the column form a rotating structure, and a vortex spring is provided at the rotating part of the baffle net, and a gear is fixed to the end of the rotating shaft of the baffle net. At the same time, the gear, rack and guide rod are all in the fixed cavity, and the fixed cavity is opened in the column. After the baffle net is pushed, it can rotate toward the column and drive the gear to rotate synchronously.

[0012] Preferably, the distribution range of the teeth on the gear is 1 / 2 of its circumference, and the side of the gear is meshed with a rack, and the top of the rack is fixedly connected to one end of the guide rod, while the other end of the guide rod is directly below the push-type alarm. When the gear rotates, it can drive the guide rod to rise through the meshing transmission with the rack.

[0013] Preferably, the adjustment mechanism includes a movable rod passing through the column, and the movable rod and the column are slidably connected, and a spring is provided on the outside of the movable rod to reset it. At the same time, an adjustment rod is fixed to the end of the movable rod away from the column. When the movable rod is pulled to slide in the column, the adjustment rod can be driven to move synchronously.

[0014] Preferably, the adjusting rod is an "L"-shaped structure, and the end of the adjusting rod away from the movable rod is engaged with the fixing hole, and the fixing holes are distributed at equal angles on the fixing plate. At the same time, the fixing plate is fixed to the base plate, and the center of rotation of the column and the center of distribution of the fixing holes are on the same horizontal axis. After the adjusting rod is separated from the fixing hole, the column can rotate, and after the adjusting rod is engaged with the fixing hole, the stability of the column after rotation can be ensured.

[0015] Preferably, the auxiliary component includes a support plate arranged in a fixed groove, and the support plate and the column are rotatably connected, and the fixed groove is opened on the side of the column. At the same time, a connecting net is pasted on the side of the support plate, and the edge of the connecting net is fixed in the fixed groove. The support plate and the connecting net are stored in the fixed groove when not in use.

[0016] Preferably, a movable plate is rotatably provided on the surface of the column, and a vortex spring is provided at the rotating shaft of the movable plate, and the end of the movable plate close to the baffle is inclined, and a connecting rod is fixed to the other end of the movable plate. When the baffle approaches the column, it can contact the movable plate and push the movable plate to rotate.

[0017] Preferably, a through groove is provided on the column on the outside of the connecting rod, and the end of the connecting rod away from the movable plate is snap-connected to the limiting hole, and the limiting hole is provided at the lower end of the support plate. At the same time, the distance between the two movable plates is smaller than the width of the baffle, and the movable plate can drive the connecting rod to separate from the limiting hole after rotation.

[0018] Compared with the existing technology, the beneficial effects of the present invention are as follows: the multi-point landslide monitoring and early warning mechanism is equipped with multiple monitoring and early warning mechanisms on the slope, which can promptly issue an alarm by detecting loose soil before a landslide occurs, and after a landslide occurs, a structure is provided to block the sediment from the landslide, thereby reducing the losses caused by the disaster. The specific contents are as follows:

[0019] 1. Press the two adjustment rods to drive the movable rod to slide on the column, so that the adjustment rods are separated from the fixing holes. In this way, the column is rotated according to the inclination angle of the base plate to make it vertical. After the adjustment is completed, release the pressure on the adjustment rods. The spring resilience can drive the adjustment rods to engage with the corresponding fixing holes, ensuring the stability of the column after the angle is adjusted;

[0020] 2. After the second fastener is inserted into the ground, the soil squeezes the movable block, causing it to rotate and adhere to the outer surface of the second fastener. When a landslide or other disaster is about to occur, the soil in which the fastener is inserted will loosen, releasing the pressure on the movable block. The vortex spring's resilience then drives the movable block to rotate outward, and the pull rope pulls the pull ring, causing the pull alarm to sound.

[0021] Furthermore, when a landslide disaster occurs, the mud and sand of the landslide can contact the retaining net and push it to rotate toward the column. When the retaining net rotates, the gear rotates, and then the meshing transmission of the gear and the rack can drive the guide rod to rise. After rising, it contacts the push-type alarm and sounds an alarm;

[0022] 3. When the retaining net rotates toward the column, it can contact the movable plate and push the movable plate to rotate, driving the connecting rod to rotate and separate from the limit hole. In this way, the support plate can rotate toward the outside of the column without restriction, and the connecting net is driven to expand during the rotation. In this way, through the setting of the connecting net and the retaining net, the landslide sediment can be blocked and reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Most existing monitoring and early warning agencies can only conduct single-point monitoring and are unable to conduct multi-point monitoring and early warning of slopes. As a result, the losses caused by disasters are increased because of the inability to issue warnings in time before landslides occur. Figure 1-Figure 4 and Figure 6-Figure 7As shown, the side of the second fastener 3 is provided with a movable block 4, and the heights of the two movable blocks 4 are different, and a vortex spring is provided at the rotation of the movable block 4, and the second fastener 3 and the first fastener 2 are both slidably connected to the bottom plate 1; the inner side of the movable block 4 is fixedly connected to one end of the traction rope 5, and the other end of the traction rope 5 is fixed on the pull ring 7, and the pull ring 7 is provided at the bottom of the pull-type alarm 6; the retaining net 10 and the column 8 form a rotating structure, and a vortex spring is provided at the rotation of the retaining net 10, and a gear 15 is fixed to the end of the rotating shaft of the retaining net 10, and the gear 15 and the rack 1 6 and the guide rod 17 are both in the fixed cavity 25, and the fixed cavity 25 is opened in the column 8; the distribution range of the gear blocks on the gear 15 is 1 / 2 of its circumference, and the side of the gear 15 is meshed with a rack 16, and the top of the rack 16 is fixedly connected to one end of the guide rod 17, while the other end of the guide rod 17 is directly below the push-type alarm 18; the fastener is above the base plate 1 when it is not in contact with the ground, and after the fastener is installed, it can pass through the base plate 1 and be inserted into the ground. When the second fastener 3 is inserted into the ground, the soil squeezes the movable block 4, which can drive the movable block 4 to rotate. The second fastener 3 is fitted with the outer surface of the second fastener 3, so that the middle section of the second fastener 3 is in a cylindrical state. When a landslide or other disaster is about to occur, the soil in which the fastener is inserted will become loose, thereby releasing the pressure on the movable block 4. In this way, the movable block 4 can be driven to rotate outward by the resilience of the vortex spring, and then the pull ring 7 is pulled by the traction rope 5 to make the pull-type alarm 6 sound an alarm, which plays an early warning role. Since the two movable blocks 4 are set at different heights and two second fasteners 3 are symmetrically arranged on the bottom plate 1, multi-point monitoring can be achieved. When a landslide disaster occurs, the mud and sand of the landslide It can contact the retaining net 10 and push the retaining net 10 to rotate toward the column 8.

In this way, the alarms issued by the pull-type alarm 6 and the press-type alarm 18 can be transmitted to the signal transmitter 9 and transmitted, which is convenient for construction personnel to deal with landslide disasters in a timely manner. When the retaining net 10 is in an inclined state, it will not affect the passage of water, and when a landslide occurs, it rotates to a vertical state, which can prevent the loss of sediment.

[0038] Example 2: When the existing monitoring and early warning mechanism is installed on the slope, it is not convenient to adjust the fit between the early warning mechanism and the slope according to the inclination angle of the slope. It requires the help of other auxiliary equipment, so the installation is not convenient enough. Therefore, this embodiment adopts the following technical solutions, such as Figure 5As shown, the adjustment mechanism includes a movable rod 11 that passes through the column 8, and the movable rod 11 and the column 8 are slidably connected, and a spring is provided on the outside of the movable rod 11 to reset it, and an adjusting rod 12 is fixed to the end of the movable rod 11 away from the column 8; the adjusting rod 12 is an "L"-shaped structure, and the end of the adjusting rod 12 away from the movable rod 11 is engaged with the fixing hole 14, and the fixing holes 14 are distributed at equal angles on the fixing plate 13, and the fixing plate 13 is fixed to the base plate 1, and the rotation center of the column 8 and the center of the distribution of the fixing holes 14 are on the same horizontal axis; when installing the monitoring and early warning mechanism, first First, the base plate 1 is brought into contact with the slope, and then the first fastener 2 and the second fastener 3 are pushed respectively to be inserted into the soil so that the base plate 1 is in close contact with the slope. Then, the two adjusting rods 12 are pressed to drive the movable rod 11 to slide on the column 8, and drive the adjusting rod 12 to separate from the fixing hole 14. In this way, the column 8 is rotated according to the inclination angle of the base plate 1 so that the column 8 is in a vertical state. After the adjustment is completed, the pressure on the adjusting rod 12 is released. In this way, the adjusting rod 12 can be driven to engage with the corresponding fixing hole 14 through the resilience of the spring, thereby ensuring the stability of the column 8 after the angle is adjusted, and also improving the convenience of installation.

[0039] Example 3: After a landslide occurs, a large amount of sediment is lost by the existing monitoring and early warning mechanism, and the monitoring and early warning mechanism does not have the function of blocking the sediment of the landslide. Therefore, this embodiment adopts the following technical solutions, such as Figures 8-10 As shown, the auxiliary component includes a support plate 19 arranged in a fixed groove 26, and the support plate 19 and the column 8 are rotatably connected, and the fixed groove 26 is opened on the side of the column 8, and the side of the support plate 19 is pasted with a connecting net 20, and the edge of the connecting net 20 is fixed in the fixed groove 26; a movable plate 21 is rotatably provided on the surface of the column 8, and a vortex spring is provided at the rotating shaft of the movable plate 21, and the end of the movable plate 21 close to the baffle 10 is inclined, and the other end of the movable plate 21 is fixed with a connecting rod 22; a through groove 23 is opened on the column 8 outside the connecting rod 22, and the end of the connecting rod 22 away from the movable plate 21 is snap-fitted to the limiting hole 24, and the limiting hole 24 is opened at the lower end of the support plate 19, and the distance between the two movable plates 21 is smaller than the width of the barrier net 10; when the barrier net 10 rotates to approach the column 8, it can contact the movable plate 21 and push the movable plate 21 to rotate.
