Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to an online monitoring device for back slope safety. Background Technology

[0002] A back slope refers to a natural or artificial slope located behind or to the side of an engineering structure such as a building, road, bridge, or tunnel. The stability of such slopes directly affects the safety of the structure in front and the surrounding people and property. Especially in mountainous areas with complex geological structures and abundant rainfall, back slopes are highly susceptible to sudden geological disasters such as landslides and collapses due to factors such as geological conditions, rainwater infiltration, weathering and erosion, and human activities. These disasters are often characterized by their high degree of concealment, great destructive power, and rapid onset; once they become unstable, the consequences are extremely serious.

[0003] To effectively prevent geological disaster risks, establishing a professional monitoring and early warning system has become a key technical means for disaster prevention and mitigation. Traditional monitoring stations mostly adopt an integrated pole structure and an integrated GNSS displacement monitoring instrument to achieve disaster early warning by collecting parameters such as surface deformation and rainfall in real time. However, existing equipment generally has this problem: most detections are reactive, that is, data is acquired and a response is made only when or after an accident occurs, which often delays the opportunity for measures such as clearing people down the slope.

[0004] In addition, the height of the integral pole is usually 2-6 meters. In steep mountainous areas where there are no roads, conventional transport vehicles and construction machinery have difficulty entering. Relying on helicopter hoisting is costly, and manual transportation is not only labor-intensive but also unsafe.

[0005] Therefore, this utility model provides an online monitoring device for back slope safety, which is used to monitor the slope status in real time and issue alarm information when the slope becomes unstable. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing an online monitoring device for back slope safety.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The back slope safety online monitoring device includes: The uprights, serving as the foundation for equipment, can be assembled in sections for easy relocation.

[0008] The monitoring equipment, installed at the top of the pole, is used to monitor the displacement of the positioning coordinates; The cabinet, located on the side of the pole, is equipped with a tilt sensor to obtain the tilt angle of the pole in real time and determine the tilt status of the installation position; it also contains a wireless transmission module for transmitting data acquired by the monitoring equipment in real time; and an alarm module with displacement and tilt angle alarm settings, which transmit alarm signals wirelessly when the set values ​​are reached. Solar power generation modules are used for self-powered electricity generation.

[0009] Preferably, the upright includes multiple sections of circular tubes connected in sequence and a base connected to the bottom end of the lowest circular tube. Each section of circular tube has flanges at both ends, and each flange has multiple corresponding through holes. An anchor rod is inserted into the through holes at the same position of the multiple flanges, and the lower end of the anchor rod is threadedly connected to a threaded cylinder fixed on the base.

[0010] Preferably, the bottom flange of the lowermost circular tube is provided with an opening that corresponds one-to-one with the threaded cylinder.

[0011] Preferably, a locking nut is screwed onto the outer wall of the threaded cylinder and rests against the end face of the lowest flange.

[0012] Preferably, the upper end of the cylinder is provided with a frustum and the lower end is provided with an inner conical surface that mates with the frustum.

[0013] Preferably, each of the two circular tubes is provided with a bracket for installing the cabinet and the solar power generation module, respectively. The bracket includes two rings, which are fixedly connected to a frame plate. The two rings abut against the opposite side of the upper and lower flanges of the circular tube.

[0014] Preferably, the ring is made up of two semi-circular buckles.

[0015] Preferably, each of the threading holes on the round tube is fitted with an isolation tube.

[0016] Compared with the prior art, this utility model provides an online monitoring device for back slope safety, which has the following beneficial effects: 1. This utility model acquires real-time location data of the monitoring position through satellite positioning and can determine the state of the back slope, such as whether it has settled, based on changes in the data. In conjunction with the installation status change data of the column detected by the tilt sensor, it cross-verifies with GNSS displacement data, thereby improving the reliability of the monitoring results. The two can complement each other well, making the displacement monitoring system more reliable, the data analysis simpler, and the characterization results more intuitive.

[0017] 2. This utility model features a segmented pole design, which reduces the burden on an individual adult and allows for independent transport without the need for coordination among multiple people, thus improving flexibility and safety when turning on rugged roads.

[0018] 3. In this utility model, each section of the circular pipe is provided with flanges at both ends, and each flange has multiple corresponding through holes. An anchor rod is inserted into the through holes at the same position on multiple flanges, and the lower end of the anchor rod is threadedly connected to a threaded cylinder fixed on the base. By connecting multiple anchor rods in series, only the number of anchor rods corresponding to the number of through holes on a single flange needs to be screwed on, eliminating the need to tighten the flanges of each section of the circular pipe with bolts, thus improving assembly efficiency.

[0019] 4. In this utility model, the upper end of the cylinder is provided with a frustum, and the lower end is provided with an inner conical surface that mates with the frustum. After docking, the frustum and the inner conical surface fit together, which can increase the bearing area of ​​the cylindrical tube docking and improve the installation stability. Through the restriction of the conical surface and the frustum, there will be no horizontal misalignment after locking with the anchor rod, reducing the impact of radial misalignment on the anchor rod compression.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0031] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0032] Example 1: To monitor the condition of the rear slope in real time, this example provides an online monitoring device for rear slope safety, comprising: Upright pole 1, serving as the foundation for the equipment's erection piles, is fastened to the pre-installed cement piles on the rear slope using bolts.

[0033] Monitoring device 2 is a GNSS antenna equipped with a radome. The radome provides rain and hail protection for the GNSS antenna, helping to maintain its stability. Monitoring device 2 is mounted on the top of pole 1. The GNSS antenna can communicate with satellites to obtain real-time location information such as latitude and longitude. It uploads the acquired satellite positioning data (i.e., configures the GPS positioning system) to the backend in real time via a 4G communication interface.

[0034] Cabinet 4 is located on the side of pole 1. Cabinet 4 contains a tilt sensor to acquire the real-time tilt angle of the pole and determine the lateral tilt status of the installation position. Cabinet 4 also contains a wireless transmission module to form a communication system with an external communication base station. The positioning data acquired by monitoring device 2 is transmitted via a transmitter, received by the backend, and processed through filtering to obtain real-time data. Changes in the acquired positioning data are used to determine the change in the installation position of pole 1, and subsequently, the displacement of the rear slope monitoring position coordinates. Cabinet 4 contains an alarm module with set values ​​for displacement and tilt angle alarms. Upon reaching the set values, an alarm signal is transmitted wirelessly to the backend. The backend is equipped with three levels of warning lights: green for normal operation, yellow for receiving an alarm signal, and red for an incident, allowing monitoring personnel to more intuitively perceive data changes. A buzzer sounds upon receiving an alarm signal, prompting the backend to react quickly.

[0035] The solar power generation module (3) is used for self-powered power generation and can maintain the operation of the equipment for a long time in the external environment.

[0036] According to the above technical solution, the location data of the monitoring position is obtained in real time through satellite positioning, and the state of the back slope, such as whether it has settled, can be determined based on the changes in the data information. In conjunction with the installation status change data of column 1 detected by the tilt sensor, the data is cross-validated with the GNSS displacement data, thereby improving the reliability of the monitoring results. The two can complement each other well, making the displacement monitoring system more reliable, the data analysis simpler, and the characterization results more intuitive.

[0037] The column 1 can be assembled in sections, and after being divided into several sections, its size becomes smaller, making it easier to move on the back slope.

[0038] Example 2 addresses the problem of conventional transport vehicles and construction machinery being unable to access steep back slopes where the integral pole 1 is difficult to access, and manual handling is inconvenient and unsafe. This example provides a segmented design for the pole 1. In this example, the pole 1 is designed as a segmented unit, divided into standardized circular tube segments 101. Each segment 101 is no more than 1.2 meters long. This length of tube 101 does not pose a significant burden for an adult to carry, and allows for independent handling without the need for multiple people to coordinate, thus improving flexibility and safety when turning on rugged roads.

[0039] In a segmented design, the conventional approach to connect each segment of the circular tube 101 involves installing a flange 102 at the joint end and securing them with bolts. This method of adjusting and tightening each segment individually is time-consuming and labor-intensive. Therefore, in this embodiment, to facilitate easy assembly of the segments and reduce assembly difficulty, flanges 102 are still integrally installed at both ends of the circular tube 101. However, the bottom end of the lowest segment of the circular tube 101 does not have a flange 102; instead, a base 105 is installed to connect to the foundation as a whole. The base 105 can be integrated with the circular tube 101 or designed separately; this design uses a separate design. Similarly, the top end of the highest segment of the circular tube 101 also does not have a flange 102; instead, an integral mounting platform is provided. Alternatively, a flange 102 could be used as the connection surface for the mounting platform. Each flange 102 has a perforation, i.e., flange 102 holes, with the same number of perforations on each flange 102 that correspond to each other. Anchor rods 103 are inserted into the same perforation on multiple flanges 102. A threaded cylinder 104, corresponding to each anchor rod 103, is fixed to the base 105. The lower end of each anchor rod 103 has an external thread, and the anchor rod 103 is screwed into the threaded cylinder 104 via this thread. In this way, by connecting multiple anchor rods 103 in series, only the number of anchor rods 103 corresponding to the number of perforations on a single flange 102 needs to be screwed in, eliminating the need to bolt each section of the circular pipe 101 to the flange 102, thus improving assembly efficiency.

[0040] According to the above technical solution, the segmented design of the pole 1 makes it easy to transport separately on the back slope, improving the safety of transportation; and the way the anchor rod 103 and the threaded cylinder 104 are assembled in series allows multiple sections of the round pipe 101 to be assembled simultaneously, thereby improving the assembly efficiency.

[0041] In this embodiment, during side-mounted assembly, the axial positioning between multiple cylinders can be achieved by passing through two anchor rods 103, and the through holes between the flanges 102 of the multiple cylindrical tubes 101 will be aligned, which greatly facilitates the subsequent insertion of the anchor rods 103. Then, the threaded cylinders 104 are connected and screwed together one by one.

[0042] In this embodiment, the monitoring device 2, which performs the monitoring function, is generally fixed on the mounting platform at the upper end of the uppermost circular pipe 101. The monitoring device 2 adopts wireless intelligent sensing technology to detect the surrounding rainfall and slope displacement, etc. (specifically, refer to GNSS monitoring stations and integrated video monitoring stations; in this solution, the monitoring device is a GNSS displacement monitoring device). A solar power generation component 3 is also typically installed for self-powered operation, reducing the need for external power input. A cabinet 4 is also provided, housing controllers, wireless / wired signal transmission components, and other related electronic equipment. The cabinet 4 and the solar power generation component 3 are generally staggered, in this case, installed on two different circular pipes 101 and arranged symmetrically.

[0043] In a further embodiment of this solution, as described in Example 3, the bottom flange 102 of the lowest circular tube 101 has an opening that corresponds one-to-one with the threaded cylinder 104. This facilitates the connection between the flange 102 of the lowest circular tube 101 and the base 105.

[0044] In a further embodiment of this solution, in Example 4, when the base 105 and the lowermost circular tube 101 are designed separately, in order to improve the tightness of the connection between the lowermost circular tube 101 and the base 105, an external thread can be provided on the outer wall of the threaded cylinder 104. After the flange 102 of the lowermost circular tube 101 is threaded through / opened onto the threaded cylinder 104, a locking nut 7 is screwed onto the outer wall of the threaded cylinder 104 to lock the circular tube 101 and the base 105 together.

[0045] In Example 5, a further embodiment of this solution, to improve the tightness of the connection between the circular pipe 101 and the flange 102, the upper end of the cylinder is provided with a frustum 5, and the lower end is provided with an inner conical surface 6 that mates with the frustum 5. After the flange 102 is connected, the frustum 5 and the inner conical surface 6 fit together, which can increase the bearing area of ​​the circular pipe 101 connection and improve the installation stability. Due to the constraint of the conical surface and the frustum 5, after locking by the anchor rod 103, there will be no horizontal misalignment, reducing the impact of radial misalignment on the anchor rod 103. Furthermore, laying a sealing gasket between the frustum 5 and the conical surface results in better sealing of the pipe connection and reduces the likelihood of water leakage compared to flat laying.

[0046] Preferably, the frustum 5 and the inner cone surface 6 can also be a truncated pyramid and an inner prism surface. Through the interlocking of non-circular regular surfaces, radial deflection will not occur between the round tubes 101, thereby reducing the torsional deformation of the anchor rod 103.

[0047] In Example 6, a further embodiment of this solution, the cabinet 4 and the solar modules are generally attached to the upright 1 by clamps or wire clips, and then locked with bolts. However, after long-term outdoor installation, the clamps may loosen and slide down due to corrosion or vibration, affecting the installation stability of the components. Therefore, in this embodiment, the mounting bracket 8 for the cabinet 4 and the solar power generation module 3 is modified: the bracket includes two rings 801 clamped to the round tube 101, and the two rings 801 are fixedly connected to the frame plate 802. The two rings 801 respectively abut against the opposite side of the upper and lower flanges 102 of the round tube 101. In this way, the abutment of the two flanges 102 prevents the equipment from sliding down.

[0048] In this embodiment, the presence of the flange 102 makes it inconvenient to install the ring 801 from top to bottom. Therefore, the ring 801 is divided into two semicircular rings, with both ends of the two semicircular rings being flat and locked with bolts. This facilitates the wrapping and installation of the ring 801 on the round pipe 101.

[0049] In Example 7, a further embodiment of this solution, both the solar power generation module 3 and the monitoring device 2 are externally mounted. Therefore, wiring is routed inside the pole 1, and holes are drilled on the pole 1 as required to serve as wiring holes. To reduce rainwater and dew seeping into the wiring holes, extension tubes are welded and fixed to the wiring holes on the circular pipe 101 as a base for securing the wiring. An isolation tube 9 is fitted between the wiring holes through which the wiring passes and the ends of the wiring extending to the outside. The opening of the isolation tube 9 is secured to the extension tube with cable ties 10, as shown in the attached diagram. Figure 8 As shown, this illustrates the installation status of the isolation pipe 9 where the wiring of monitoring device 2 extends into the pole 1. The extension pipe that connects the isolation pipe 9 to the pole 1 is located at the axis of the installation platform, and the outer wall of the extension pipe has multiple notches in a ring array, serving as a heat dissipation channel inside the pole 1. These notches are covered by the isolation pipe 9, so rainwater and dew will only flow downwards and will not surge upwards from the notches.

[0050] In this design, the mating threads between the anchor rod 103 and the threaded cylinder 104, and between the threaded cylinder 104 and the locking nut 7 (i.e., the bolt fasteners) are all self-locking.
