Description

Technical Field

[0001] The invention belongs to the technical field of geotechnical engineering monitoring, and in particular relates to a slope stability monitoring device. Background Art

[0002] Slope stability monitoring is an important measure to conduct real-time or regular observations of slope deformation, stress, groundwater and other parameters through scientific methods and technical means to assess its stability and warn of potential disasters.

[0003] The existing patent with announcement number CN210946763U discloses a slope deformation monitoring system, including a monitoring device installed at a position far away from the slope, several target lights and a set of reference light groups set on the slope. The monitoring device includes a control unit, a CCD detector, a lens and a filter. The center wavelength of the filter matches the emission spectrum of the target light and the reference light group; the target light is set at the monitored part of the slope, and the reference light group includes three reference lights and an L-shaped component composed of vertical support rods and horizontal support rods. The three reference lights are respectively set at the two ends and the center intersection of the L-shaped component.

[0004] The existing technology has the following defects:

[0005] Monitoring needs to be based on target lights, but the target lights can only be set up to monitor slope deformation based on points. In order to obtain more refined monitoring data, the setting density of target lights needs to be increased, and each target light needs to be installed manually, thereby increasing the installation workload. Summary of the Invention

[0006] The present invention provides a slope stability monitoring device, which can solve the problem in the prior art that in order to obtain more refined monitoring data, the setting density of target lights needs to be increased, thereby increasing the installation workload.

[0007] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0008] The present application provides a slope stability monitoring device, which includes a rod body, a projectile unit, a marking net, an identification unit and a control unit. The rod body is arranged on the side of the highway away from the slope; the projectile unit is adjustably connected to the rod body, and the projectile unit has a plurality of throwable anchor rods; the four corners of the marking net are connected to the anchor rods, and the marking net is unfolded as the anchor rods are thrown, and the marking net is laid on the surface of the slope after being unfolded; the identification unit is connected to the top of the rod body, and the identification unit is used to identify the signal fed back by the marking net; the control unit receives the signal identified by the identification unit, stores and compares it, and obtains the deformation amount of the marking net.

[0009] Through the above technical solution, the marking net is projected onto the slope to achieve rapid on-site installation by one person. There is no need for installers to climb up the slope to place the markers one by one, which greatly reduces the workload of marker installation.

[0010] In the present invention, the projectile unit comprises a launching tube, a solenoid valve and an air source, wherein the multiple launching tubes are rotatably connected to the rod body, and the anchor rod is inserted into the launching tube; the solenoid valve is connected to the rod body, and the solenoid valve is connected to an air pipe, and the air pipe is connected to the launching tube; the air source is inserted into the solenoid valve;

[0011] The electromagnetic valve allows the gas of the gas source to pass through the gas pipe and into the launching tube at the same time. When the gas enters the launching tube, it pushes the anchor rod to fly toward the slope.

[0012] Through the above technical solution, the anchor rod is launched by using a solenoid valve to start the air source, which improves the synchronization and environmental friendliness of the drive.

[0013] In the present invention, the rod body is connected to a mounting rod, and the mounting rod and the rod body are perpendicular to each other;

[0014] The ejection unit further comprises an indexing plate and an adjusting ring which are connected to each other. The adjusting ring is rotatably connected to the mounting rod, and one end of the indexing plate which is away from the adjusting ring is connected to the outer side of the launching tube.

[0015] Through the above technical solution, the two rotational degrees of freedom of the launch tube are adjusted by using a dividing plate and an adjustment ring, thereby meeting the adaptability of projecting onto the slope in different distance environments and different marking network sizes.

[0016] In the present invention, the marking net has a wire core, and a plurality of corner cube prisms are connected to the outer surface of the wire core;

[0017] The identification unit comprises a laser transmitter and a laser receiver. The laser transmitter emits laser light toward the corner cube prism, and the laser light reflected by the corner cube prism is received by the laser receiver.

[0018] Through the above technical solution, micro-corner cube prisms are evenly distributed on the outside of the wire core, so that the marking network has the effect of reflecting laser at multiple angles, thereby improving the recognition efficiency of the marking network.

[0019] In the present invention, the slope stability monitoring device further comprises a supporting rod connected to the side of the rod body facing the slope, and the supporting rod is used to support the marking net that has not been projected.

[0020] Through the above technical solution, the marking net is held up by a supporting rod, which reduces the friction between the marking net and the ground during projection and avoids the wear of the corner cube prisms on the surface of the marking net.

[0021] In the present invention, the slope stability monitoring device further includes a solar panel connected to the top of the rod, and the solar panel is electrically connected to the control unit.

[0022] Through the above technical solution, the use of solar panels for power supply can avoid the inability to obtain slope data due to large-scale power outages caused by blockage of fixed transmission lines.

[0023] In the present invention, the slope stability monitoring device further includes a universal ball joint connected between the solar panel and the rod body.

[0024] Through the above technical solution, a universal ball joint is used to increase the angle adjustment range of the solar panel and improve the solar energy conversion efficiency.

[0025] In the present invention, the slope stability monitoring device further includes a warning light connected to the top of the pole body, the warning light being electrically connected to the control unit, and the warning light emitting light of different colors based on the deformation of the marking net.

[0026] Through the above technical solution, warning lights can be used to warn nearby vehicles traveling on the road, so that drivers can make judgments in advance based on the color of the warning lights, thereby improving road driving safety.

[0027] In the present invention, the above-mentioned slope stability monitoring device also includes a drone nest and a drone. The drone nest is connected to the opening at the top of the pole body, and the drone nest is electrically connected to the control unit; the drone is parked in the drone nest, and when the deformation of the marking network exceeds a preset value, the drone takes off and shoots the information of the slope and feeds back.

[0028] Through the above technical solution, using a built-in drone, even if a landslide occurs and causes damage to the main body of the device, it is still possible to obtain images of the road and slope at the time of the landslide through the drone before the damage occurs, and then determine the landslide loss and organize rescue in time.

[0029] In the present invention, the slope stability monitoring device further includes a protective cover, which is rotatably connected to the opening of the drone nest, and the protective cover is electrically connected to the control unit.

[0030] Through the above technical solution, the rotating protective cover is adopted, which can facilitate the flying out of the drone when in use and the protection when not in use. BRIEF DESCRIPTION OF THE DRAWINGS

For example, they can refer to welding, bolting, or riveting; fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0048] Example:

[0049] Please refer to Figures 1 to 11 , Figures 1 to 11 An embodiment of the present application is shown.

[0050] This embodiment provides a slope stability monitoring device, such as Figure 1 and Figure 7 As shown, it includes a rod body 6, a projectile unit 1, a marking net 105, an identification unit 201 and a control unit 202. The rod body 6 is set on the side of the road 7 away from the slope 8; Figure 2 As shown, the projectile unit 1 is adjustable and connected to the rod body 6, and the projectile unit 1 has a plurality of throwable anchor rods 101; Figure 7 and Figure 8 As shown, the four corners of the marking net 105 are connected to the anchor rod 101, and the marking net 105 is unfolded as the anchor rod 101 is thrown out. After unfolding, the marking net 105 is laid on the surface of the slope 8; the identification unit 201 is connected to the top of the rod body 6, and the identification unit 201 is used to identify the signal fed back by the marking net 105; the control unit 202 receives the signal identified by the identification unit 201, stores and compares it to obtain the deformation of the marking net 105.

[0051] When installing, if Figure 7 As shown, the base and bolts at the lower part of the rod body 6 are connected by pre-embedded concrete bolts, and the ejection unit 1 connects the solenoid valve 103 and the launch tube 102 to the middle part of the rod body 6 respectively by means of a ring buckle, as shown in FIG. Figure 5 and Figure 8 As shown, remove the threaded fixing ring 1013 from the anchor rod 101, insert the circular rings on the four corners of the marking net 105 into the front end of the anchor rod 101, and re-lock the fixing ring 1013. Clamp the marking net 105 through the fixing ring 1013 and the positioning ring 1012, as shown in FIG. Figure 1 As shown, the identification unit 201 and the control unit 202 are also connected to the top of the rod body 6 through a buckle.

[0052] When using, such as Figure 10 As shown, the angle of the launch tube 102 is adjusted to tilt toward the right outside, as shown in FIG. Figure 1 As shown, eight compressed gas cylinders are connected as gas sources 104 to the lower end of the electromagnetic valve 103, and the four launch tubes 102 are ventilated at the same time by starting the electromagnetic valve 103. Figure 5 As shown, the compressed gas enters the tail of the launch tube 102 through the air pipe 1031, and then pushes the tail slot 1011 integrated with the tail of the anchor rod 101, causing the anchor rod 101 to fly out. Figure 5 As shown, the positioning ring 1012 and the fixing ring 1013 are both threadedly connected to the anchor rod 101. The flight parabola of the anchor rod 101 can be adjusted by replacing the fixing ring 1013 with different weights. The center of gravity of the anchor rod 101 can be adjusted by adjusting the position of the positioning ring 1012 to make the anchor rod 101 fly smoothly. Figure 11As shown, because the anchor rods 101 at the lower ends of the four launch tubes 102 are heavier than the anchor rods 101 at the upper ends, the parabolas of the two lower anchor rods 101 are lower than the two upper anchor rods 101, which allows the marking net 105 to be deployed up and down. Figure 10 As shown, the left and right launching tubes 102 are adjusted to expand outwards, and the anchor rods 101 cause the marking net 105 to unfold to both ends.

[0053] It should be noted that the specific weight of the fixing ring 1013, the specific position of the positioning ring 1012, and the size and weight of the marking net 105 all require calculation of specific parameters after field exploration. These specific parameters do not fall within the scope of protection of this application and are therefore not further described or limited herein. The ejection of the anchor rod 101 is based on the principle of a blow needle. The balance wing can also be adaptively added according to the ejection distance (reference arrow flight). Compared with the prior art that uses 3 or 4 marking points, the entire marking net 105 can be used as a marking point with denser marking points. Because the marking net 105 is deployed during flight, this embodiment is only applicable to artificial slopes 8 (such as Figure 7 The monitoring of the side slope of the highway project shown in the figure) or the natural slope 8 without tall shrubs is not suitable for the natural slope 8 with tall shrubs in the natural environment. The deformation of the marking net 105 comes from the loosening of the anchor rod 101 due to the instability of the slope 8 or the displacement of the marking net 105 caused by the sliding and pulling of the surface soil.

[0054] Through the above technical solution, the marking net 105 is projected onto the slope 8 to achieve rapid installation by one person on site. There is no need for the installer to climb up the slope 8 to place the markers one by one, which greatly reduces the workload of marker installation.

[0055] As a better implementation method, Figure 1 As shown, the projectile unit 1 comprises a launch tube 102, a solenoid valve 103 and an air source 104. The air source 104 is a gas cylinder filled with compressed air. The multiple launch tubes 102 are rotatably connected to the rod body 6, and the anchor rod 101 is inserted into the launch tube 102; the solenoid valve 103 is connected to the rod body 6, and the solenoid valve 103 is connected to the air pipe 1031, which is in communication with the launch tube 102; the air source 104 is inserted into the solenoid valve 103;

[0056] The electromagnetic valve 103 simultaneously passes the gas from the gas source 104 into the launch tube 102 through the gas pipe 1031 . When the gas enters the launch tube 102 , it pushes the anchor rod 101 to fly toward the slope 8 .

[0057] It should be noted that, in addition to being adjusted according to the above-mentioned positioning ring 1012 and fixing ring 1013, the different flight trajectories of the anchor rod 101 can also be adjusted by installing a flow limiting valve at the adapter 1021 and changing the amount of gas entering the launch tube 102 to adjust the parabola of the projection and thus realize the deployment of the marking net 105.

[0058] Through the above technical solution, the anchor rod 101 is launched by using the electromagnetic valve 103 to start the air source 104, thereby improving synchronization and environmental friendliness of the drive.

[0059] As a better implementation method, Figure 1 and Figure 2 As shown, the rod body 6 is connected to a mounting rod 601, and the mounting rod 601 and the rod body 6 are perpendicular to each other;

[0060] The projectile unit 1 further comprises a dividing plate 1022 and an adjusting ring 1023 which are connected to each other. The adjusting ring 1023 is rotatably connected to the mounting rod 601 , and one end of the dividing plate 1022 which is away from the adjusting ring 1023 is connected to the outside of the launching tube 102 .

[0061] Specifically, the indexing plate 1022 uses springs and marbles to achieve angle positioning because it needs precise positioning, while the adjustment ring 1023 is clamped by screw locking for rough positioning. Figure 2 As shown, both the dividing plate 1022 and the adjusting ring 1023 are engraved with angle scales.

[0062] Through the above technical solution, the dividing plate 1022 and the adjustment ring 1023 are used to realize the adjustment of the two rotational degrees of freedom of the launch tube 102, thereby meeting the adaptability of projecting toward the slope 8 under different distance environments and different marking net 105 sizes.

[0063] As a better implementation method, Figure 9 As shown, the marking network 105 has a core 1051, and a plurality of corner cube prisms 1053 are connected to the outer surface of the core 1051;

[0064] The identification unit 201 includes a laser transmitter and a laser receiver. The laser transmitter emits laser light toward the corner cube prism 1053 , and the laser light reflected by the corner cube prism 1053 is received by the laser receiver.

[0065] It should be noted that, exemplarily, the core 1051 is made of polymer fiber material, polar groups are introduced into the surface through plasma treatment, and then UV glue is used as the adhesion layer 1052 and nanoimprint technology is used to connect the micro-corner prism 1053 to the outside of the core 1051, and the connection is completed by photocuring. However, the specific material and specific connection method of the corner cube prism 1053 can be obtained by those skilled in the art through public technical solutions. The parameters and model of the light transmitter and the parameters and model of the laser receiver can be purchased or customized through public channels after calculation based on the actual construction situation. The parameters and model of the light transmitter and the parameters and model of the laser receiver as well as the specific materials and specific connection method of the corner cube prism 1053 do not fall within the scope of protection of this application and are therefore not further explained or specifically limited.

[0066] Through the above technical solution, the micro-corner cube prisms 1053 are evenly distributed outside the wire core 1051, so that the marking network 105 has the effect of reflecting laser light at multiple angles, thereby improving the recognition efficiency of the marking network 105.

[0067] As a better implementation method, Figure 4 and Figure 5 As shown, the slope stability monitoring device further includes a supporting rod 602 , which is connected to the side of the rod body 6 facing the slope 8 , and is used to support the unprojected marking net 105 .

[0068] When in use, in addition to the four corners of the marking net 105 being connected to the four anchor rods 101 respectively, because the unfolded marking net 105 is too long, it can be hung on the supporting rod 602 by folding (because the lines of the marking net 105 are complicated after folding, it is omitted in the drawing).

[0069] Through the above technical solution, the support rod 602 is used to hold up the marking net 105, thereby reducing the friction between the marking net 105 and the ground during projection, and preventing the corner cube prisms 1053 on the surface of the marking net 105 from being worn.

[0070] As a better implementation method, Figure 1 and Figure 10 As shown, the slope stability monitoring device further includes a solar panel 301 . The solar panel 301 is connected to the top of the rod 6 , and the solar panel 301 is electrically connected to the control unit 202 .

[0071] It should be noted that the solar panel 301 is only a device for converting solar energy and electrical energy. The converted electrical energy needs to be stored through the inverter and accumulator arranged in the control unit 202, and the stored electrical energy is used to power the device electrically connected to the control unit 202. The specific complete set of solar power supply circuits can be purchased by those skilled in the art through public channels, so no further explanation or specific limitation is given here. At the same time, according to the power distribution at the location of Highway 7, pure solar power supply or solar power + cable power supply can be selected.

[0072] Through the above technical solution, the solar panel 301 is used for power supply, which can avoid the inability to obtain the slope 8 data due to large-scale power outages caused by the blocking of fixed power transmission lines.

[0073] As a better implementation method, Figure 3 and Figure 6 As shown, the slope stability monitoring device further includes a universal ball joint 302 , which is connected between the solar panel 301 and the rod 6 .

[0074] During use, after loosening the locking ring 3023 , the angle of the solar panel 301 can be changed by relative sliding of the ball head 3021 and the ball sleeve 3022 , and then the locking ring 3023 can be tightened to position the solar panel 301 .

[0075] Through the above technical solution, the universal ball joint 302 is used to increase the angle adjustment range of the solar panel 301 and improve the solar energy conversion efficiency.

[0076] As a better implementation method, Figure 1 As shown, the slope stability monitoring device further includes a warning light 4 , which is connected to the top of the rod 6 . The warning light 4 is electrically connected to the control unit 202 , and emits light of different colors based on the deformation of the marking net 105 .

[0077] The data model of the slope 8 is obtained based on the preliminary exploration, and then the safe deformation amount and the dangerous deformation amount that will trigger the landslide are calculated. When the marking network 105 has not deformed, the warning light 4 emits green light. When a safe deformation occurs, the warning light 4 emits yellow light and makes a judgment based on the accumulated value of several deformation amounts. When the accumulated deformation is still within the safe deformation amount, the yellow light remains to remind the driver to pass quickly and not to stop. When the deformation does not continue to occur, the green light is restored. When the accumulated deformation reaches the dangerous deformation amount, the red light is emitted to warn the driver to stop and pass.

[0078] It should be noted that the warning light 4 uses LED lamp beads, and the specific control circuit and circuit elements for data analysis are all public technical solutions, which can be obtained by technical personnel in this field as needed. No further explanation or specific limitation is given here. The circuit setting and the selection of circuit elements do not fall within the scope of protection of this application.

[0079] Through the above technical solution, the warning light 4 can be used to warn nearby vehicles traveling on the highway 7, so that the driver can make judgments in advance based on the color of the warning light 4, thereby improving road driving safety.

[0080] As a better implementation method, Figure 10 As shown, the above-mentioned slope stability monitoring device also includes a drone nest 502 and a drone 503. The drone nest 502 is connected to the opening at the top of the rod body 6, and the drone nest 502 is electrically connected to the control unit 202; the drone 503 is parked in the drone nest 502. When the deformation of the marking network 105 exceeds the preset value, the drone 503 takes off and shoots the information of the slope 8 and feeds back.

[0081] It should be noted that the exemplary UAV 503 can be a micro-ducted UAV, which is used to adapt to the complex environment caused by the turbulent airflow caused by the landslide. The UAV 503 is charged by the charger 504 through the control unit 202. The UAV 503 has the function of shooting and wireless data transmission. The charger 504 can use wireless charging. Based on these requirements, those skilled in the art can purchase UAVs 503 that meet these functions through the open market. Therefore, no further explanation or further limitation will be given here. Any UAV 503 that meets the above functions can be used.

[0082] Through the above technical solution, using the built-in drone 503, even if a landslide occurs and causes damage to the device body, the drone 503 can still be used to obtain images of the road and slope 8 at the time of the landslide before the damage occurs, thereby determining the landslide loss and organizing rescue in a timely manner.

[0083] As a better implementation method, Figure 1 and Figure 10 As shown, the above-mentioned slope stability monitoring device also includes a protective cover 501, which is rotatably connected to the opening of the drone nest 502, and the protective cover 501 is electrically connected to the control unit 202.

[0084] Through the above technical solution, the rotating protective cover 501 is used to facilitate the flying out of the drone 503 when in use and to protect it when not in use.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
