Description

Technical Field

[0001] This invention relates to the field of geological disaster monitoring equipment technology, and in particular to a traditional village geological disaster monitoring and early warning device and its usage method. Background Technology

[0002] Geological disasters are natural disasters primarily caused by geological dynamic activities or abnormal changes in the geological environment. Under the influence of internal or external forces or anthropogenic geological forces, the Earth experiences abnormal energy release, material movement, deformation and displacement of rock and soil masses, and abnormal environmental changes. These phenomena or processes endanger human life and property, disrupt daily life and economic activities, or damage the resources and environment upon which humanity depends for survival and development, posing a significant threat to people's safety and property.

[0003] Traditional villages, also known as ancient villages, refer to villages that were formed relatively early, possess rich cultural and natural resources, and have certain historical, cultural, scientific, artistic, economic, and social value, thus deserving protection. Geographically, these traditional villages are often located in relatively isolated and underdeveloped areas with outdated information transmission methods. Without specific early warning channels, it is difficult to effectively communicate disaster information. From a lifestyle and cultural perspective, traditional villages are often built along mountains and rivers for convenience, making them vulnerable to geological disasters such as mudslides, floods, and landslides. From a social development perspective, with socio-economic development, various human engineering activities have significantly increased, becoming a direct cause and a major driving force for geological disasters in traditional villages. Therefore, monitoring equipment and devices for geological disasters play a crucial role in the monitoring, early warning, and protection of traditional villages, mitigating the threat and damage caused by geological disasters.

[0004] Currently, conventional geological disaster monitoring and early warning devices typically include multiple sensors, such as tilt sensors, displacement sensors, and humidity sensors, for monitoring. However, sensors that are related to the external environment, such as tilt sensors, displacement sensors, and humidity sensors, are easily affected by external factors, resulting in poor monitoring performance. Furthermore, they cannot provide real-time indications of the location and extent of landslides, debris flows, etc., which can easily mislead the public into making incorrect judgments.

[0005] Therefore, it is necessary to provide a traditional village geological disaster monitoring and early warning device to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a traditional village geological disaster monitoring and early warning device, comprising a monitoring body with pressure detection structures arranged around its periphery. The lower end of the monitoring body is fixedly connected to the interior of a mounting base. In use, the device is installed and fixed in a designated location according to the geological disaster monitoring and early warning usage method, and is arranged at multiple equidistant locations based on the terrain. Then, wiring is laid for use. During use, the monitoring body monitors geological dynamic activities or abnormal changes in the geological environment, debris flows, landslides, and other conditions in the area. If any abnormality occurs, an early warning will be issued in a timely manner.

[0007] The monitoring body includes a monitoring column, a control body, a light alarm component, and an internal detection rod. The control body is fixedly connected to the upper end of the monitoring column. The light alarm component is electrically connected to the center of the upper surface of the control body. The internal detection rod is movably connected inside the monitoring column. The internal detection rod is electrically connected to the control body through a circuit.

[0008] The pressure detection structure includes a baffle, a bracket is fixedly connected to the center of the concave surface of the baffle, and a pressure sensor is movably connected to the end of the bracket away from the baffle. The pressure sensor is fixedly connected to a fixing hole opened on the surface of the monitoring column. By setting up the baffle, the bracket and the pressure sensor, the continuous pressure can be judged according to the pressure conditions around the perimeter, and an early warning can be issued to the terminal based on this.

[0009] Preferably, the monitoring column has an offset hole inside, and a displacement monitoring chamber communicating with the offset hole is opened at the upper end of the monitoring column. A motion support ring is fixedly connected to the center position inside the displacement monitoring chamber.

[0010] Preferably, the light alarm component includes a high-intensity alarm light, which is electrically connected to and fixed to the upper end of the solar power module. The solar power module is electrically connected to and fixed to the center of the upper surface of the control body. By setting up the light alarm component, the power supply can be cut off in time according to the geological dynamic activity warning issued by the control body, and the solar power module can be activated to supply power to the high-intensity alarm light, causing the high-intensity alarm light to flash. With the cooperation of multiple geological disaster monitoring and early warning devices, the disaster area can be roughly understood according to the light signal, which not only facilitates understanding the situation and carrying out rescue, but also avoids accidentally entering dangerous areas.

[0011] Preferably, an offset ball is fitted onto the upper middle position of the internal detection rod and is movably connected to the inside of the offset hole via the offset ball. A displacement transmission ball is fixedly connected to the upper end of the internal detection rod. The circumferential side of the displacement transmission ball contacts multiple label rods arranged around the ball. The label rods are movably connected to a ball groove opened inside the moving support ring via a center-of-gravity ball at the middle position. A detection label is provided at the other end of the label rod, with the label facing the laser detector. The laser detector is electrically connected to the control unit via a circuit. The laser detector is fixedly connected to a slot opened in the inner wall of the displacement monitoring chamber at the upper end of the monitoring column. A humidity capsule is fixedly connected to the lower end of the internal detection rod. A humidity sensor is placed inside the humidity capsule and is electrically connected to the control unit via a circuit. By configuring a monitoring column, moving support ring, internal detection rod, offset ball, displacement transmission ball, tag ball rod, and laser detector, real-time and accurate detection and early warning of the direction of geological dynamic activity can be achieved through reverse monitoring. Compared with monitoring sensors connected to the external environment, setting the monitoring components internally, through internal triggering and internal monitoring, can greatly avoid interference from the external environment on the monitoring data, further improving the accuracy of the monitoring data and avoiding false alarms and missed alarms, resulting in better stability. By fixing a humidity capsule at the lower end of the internal detection rod and installing a humidity sensor inside the humidity capsule, the humidity underground can be monitored in real time, accurately grasping the changes in the surrounding humidity, thereby enabling the monitoring and early warning of soil erosion, desertification, and other conditions.

[0012] Preferably, the offset hole has a groove at the position of the corresponding offset ball.

[0013] Preferably, the motion support ring has multiple ball grooves inside for movably connecting with the label stick.

[0014] Preferably, the humidity capsule has through holes that are evenly distributed in the middle of its surface, sloping upwards from the outside in.

[0015] Preferably, the label stick has a center-of-gravity sphere fixed at the middle position according to the principle of center of gravity, and both ends are spherical structures.

[0016] A preferred method for using a traditional village geological disaster monitoring and early warning device includes the following specific steps:

[0017] S1. A mounting base with a through hole is pre-drilled at the designated location, and a smooth, deep hole with enough space for the internal detection rod is drilled using an electric drill. The mounting base is then fixed in the middle of the base.

[0018] S2. Remove the main monitoring unit, stably support the monitoring column, align the humidity capsule at the lower end of the internal detection rod with the drilled hole, and slowly lower it until the lower end of the monitoring column is stably inserted into the mounting base. Then, use bolts to fix the mounting base to the monitoring column.

[0019] S3. Connect the control unit to power, check and initialize the status of the light alarm component, pressure sensor and laser detector, and it is ready for use.

[0020] Compared with existing technologies, the present invention provides a traditional village geological disaster monitoring and early warning device, which has the following beneficial effects:

[0021] This invention, through the setup of a monitoring column, a moving support ring, an internal detection rod, an offset ball, a displacement transmission ball, a tag ball rod, and a laser detector, enables real-time and accurate detection and early warning of the direction of geological dynamic activity in a reverse monitoring manner. Compared with monitoring sensors that are connected to the external environment, placing the monitoring components internally, through internal triggering and internal monitoring, can greatly avoid interference from the external environment on the monitoring data, further improve the accuracy of the monitoring data, and also avoid false alarms and missed alarms, resulting in better stability in use.

[0022] This invention, by fixing a humidity capsule at the lower end of an internal detection rod and installing a humidity sensor inside the humidity capsule, can monitor the humidity underground in real time and accurately grasp the changes in the surrounding humidity. This enables the monitoring and early warning of soil erosion, desertification, and other issues.

[0023] By setting up baffles, brackets and pressure sensors, this invention can determine the continuous pressure based on the pressure conditions around the perimeter and issue a warning to the terminal accordingly.

[0024] This invention, through the installation of high-intensity alarm lights and solar power modules, and in conjunction with multiple geological disaster monitoring and early warning devices, can provide light warnings while also allowing for a general understanding of the affected area based on the light signals. This not only facilitates understanding the situation and enabling rescue efforts, but also helps prevent people from accidentally entering dangerous areas and causing unnecessary losses.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figures 1 to 8 This invention relates to a traditional village geological disaster monitoring and early warning device, comprising a monitoring body 1, with pressure detection structures 2 arranged around the periphery of the monitoring body 1, and the lower end of the monitoring body 1 fixedly connected to the interior of the mounting base 3. In use, the device is installed and fixed in a designated location according to the geological disaster monitoring and early warning usage method, and is arranged at multiple equidistant locations according to the terrain. Then, the wiring is laid and it can be used. During use, the monitoring body 1 will monitor the geological dynamic activities, abnormal changes in the geological environment, debris flows, landslides, etc. in the area, and will issue an early warning in a timely manner if any abnormality occurs.

[0037] The monitoring body 1 includes a monitoring column 101, a control body 102, and an internal detection rod 104. The control body 102 is fixedly connected to the upper end of the monitoring column 101. The internal detection rod 104, which is used to monitor geological dynamic activities or abnormal changes in the geological environment, is movably connected inside the monitoring column 101. The internal detection rod 104 is electrically connected to the control body 102 through a line.

[0038] The monitoring column 101 has an offset hole 1011 inside. The offset hole 1011 has a ball groove at the position corresponding to the offset ball 1041. The upper end of the monitoring column 101 has a displacement monitoring chamber 1012 that communicates with the offset hole 1011. A motion support ring 1013 is fixedly connected to the center position inside the displacement monitoring chamber 1012. The motion support ring 1013 has multiple ball grooves inside for movable connection with the label ball rod 1045.

[0039] An offset ball 1041 is fitted onto the upper middle position of the internal detection rod 104, and is movably connected to the interior of the offset hole 1011 via the offset ball 1041. A displacement transmission ball 1042 is fixedly connected to the upper end of the internal detection rod 104. The peripheral side of the displacement transmission ball 1042 contacts multiple label ball rods 1045 arranged around the sphere. A center-of-gravity sphere is fixed at the middle position of the label ball rod 1045 according to the principle of center of gravity, and is movably connected to a ball groove opened inside the motion support ring 1013 via the center-of-gravity sphere at the middle position. Both ends are spherical structures, with one end being... A detection label is placed on the laser detector 1046, which is electrically connected to the control body 102 via a circuit. The laser detector 1046 is fixedly connected to the slot in the inner wall of the displacement monitoring chamber 1012 at the upper end of the monitoring column 101. A humidity capsule 1043 is fixedly connected to the lower end of the detection rod 104. A through hole with an upward inclination from the outside to the inside is evenly opened in the middle of the surface of the humidity capsule 1043. A humidity sensor 1044 is placed inside the capsule. The humidity sensor 1044 is electrically connected to the control body 102 via a circuit.

[0040] During use, if geological dynamic activity or abnormal changes in the geological environment occur, it will be directly transmitted through the ground and act on the rod body of the internal detection rod 104 located underground. This causes the internal detection rod 104 to move and deflect in the direction of geological activity within the offset hole 1011, using the offset ball 1041 as a fulcrum. Simultaneously, the lower end of the internal detection rod 104 deflects in the opposite direction, accompanied by the upper displacement transmission ball 1042, maintaining this deflection. The displacement transmission ball 1042, maintaining its deflection, will continuously push the tag ball rod 1045 in the opposite direction of geological activity. The tag ball rod 1045... The ball will be pushed and deflected along the center of gravity sphere. At this time, the ball end with the detection tag will deviate from the detection range of the laser detector 1046, and the laser detector 1046 will feed back an error signal to the control body 102. The control body 102 will then provide feedback to the terminal. If the geological environment changes abnormally, the humidity diffused from the ground to the inside of the humidity capsule 1043 will increase or decrease abnormally. At this time, the humidity sensor 1044 located inside the humidity capsule 1043 will feed back the detected data to the control body 102, and the control body 102 will feed back the data to the control terminal to provide an early warning to the control terminal.

[0041] In this embodiment, by setting up the monitoring column 101, the motion support ring 1013, the internal detection rod 104, the offset ball 1041, the displacement transmission ball 1042, the tag ball rod 1045, and the laser detector 1046, the direction of geological dynamic activity can be accurately detected and warned in real time through reverse monitoring. Compared with monitoring sensors that are in contact with the external environment, setting the monitoring components internally, and using internal triggering and internal monitoring, can greatly avoid the interference of the external environment on the monitoring data, further improve the accuracy of the monitoring data, and also avoid false alarms and missed alarms, resulting in better stability. By fixing the humidity capsule 1043 at the lower end of the internal detection rod 104 and installing the humidity sensor 1044 inside the humidity capsule 1043, the humidity of the ground can be monitored in real time, accurately grasping the changes in the surrounding humidity, thereby realizing the monitoring and early warning of soil erosion, desertification, and other conditions.

[0042] Example 2

[0043] Please see Figure 1 , 3 This embodiment further describes Example 1. The pressure detection structure 2 includes a baffle 201. A bracket 2011 is fixedly connected to the center of the concave surface of the baffle 201. The bracket 2011 is movably connected to the pressure sensor 202 at the end away from the baffle 201. The pressure sensor 202 is fixedly connected to a fixing hole opened on the surface of the monitoring column 101.

[0044] When in use, if a mudslide or landslide occurs, it will directly act on the surface of the baffle 201 and push the baffle 201 in the direction of flow. The baffle 201 will apply pressure to the pressure sensor 202 through the bracket 2011. When the pressure sensor 202 detects continuous pressure, it will feed back to the control body 102, and the control body 102 will issue an early warning to the terminal.

[0045] In this embodiment, by setting up the baffle 201, the bracket 2011 and the pressure sensor 202, the continuous pressure can be judged according to the pressure situation on the periphery, and an early warning can be issued to the terminal based on this.

[0046] Example 3

[0047] Please see Figure 1 , 2 4. In this embodiment, the monitoring body 1 further includes a light alarm component 103, and the light alarm component 103 is electrically connected to the center position of the upper surface of the control body 102.

[0048] The light alarm assembly 103 includes a high-intensity alarm light 1031, which is electrically connected to and fixed to the upper end of the solar power module 1032. The solar power module 1032 is electrically connected to and fixed to the center of the upper surface of the control body 102.

[0049] When in use, it will cut off the power supply in a timely manner based on the geological dynamic activity warning issued by the control body 102, and activate the solar power module 1032 to supply power to the high-intensity alarm light 1031, so that the high-intensity alarm light 1031 will emit a flashing alarm.

[0050] In this embodiment, by setting up a high-intensity alarm light 1031 and a solar power module 1032, and cooperating with multiple geological disaster monitoring and early warning devices, while providing light warnings, the affected area can also be roughly understood based on the light signals. This not only facilitates understanding the situation and carrying out rescue operations, but also avoids accidentally entering dangerous areas and causing unnecessary losses.

[0051] Working principle and usage process of this invention:

[0052] During use, if geological dynamic activity or abnormal changes in the geological environment occur, it will be directly transmitted through the ground and act on the rod body of the internal detection rod 104 located underground. This causes the internal detection rod 104 to move and deflect in the direction of geological activity within the offset hole 1011, using the offset ball 1041 as a fulcrum. Simultaneously, the lower end of the internal detection rod 104 deflects in the opposite direction, accompanied by the upper displacement transmission ball 1042, maintaining this deflection. The displacement transmission ball 1042, maintaining its deflection, will continuously push the tag ball rod 1045 in the opposite direction of geological activity. The tag ball rod 1045... The ball will be pushed and deflected along the center of gravity sphere. At this time, the ball end with the detection tag will deviate from the detection range of the laser detector 1046, and the laser detector 1046 will feed back an error signal to the control body 102. The control body 102 will then provide feedback to the terminal. If the geological environment changes abnormally, the humidity diffused from the ground to the inside of the humidity capsule 1043 will increase or decrease abnormally. At this time, the humidity sensor 1044 located inside the humidity capsule 1043 will feed back the detected data to the control body 102, and the control body 102 will feed back the data to the control terminal to provide an early warning to the control terminal.

[0053] When in use, if a mudslide or landslide occurs, it will directly act on the surface of the baffle 201 and push the baffle 201 in the direction of flow. The baffle 201 will apply pressure to the pressure sensor 202 through the bracket 2011. When the pressure sensor 202 detects continuous pressure, it will feed back to the control body 102, and the control body 102 will issue an early warning to the terminal.

[0054] When in use, it will promptly cut off the power supply based on the geological dynamic activity warning issued by the control body 102, and activate the solar power module 1032 to supply power to the high-intensity alarm light 1031, causing the high-intensity alarm light 1031 to flash alarm. With the cooperation of multiple geological disaster monitoring and early warning devices, the disaster area can be roughly understood based on the light signal, which not only facilitates understanding the situation and carrying out rescue, but also avoids accidentally entering dangerous areas.

[0055] This application also discloses a method for using a traditional village geological disaster monitoring and early warning device, the specific steps of which are as follows:

[0056] S1. A mounting base with a through hole is pre-reserved at the designated location, and a smooth, deep hole with enough internal detection rod 104 is drilled using an electric drill at the through hole location. Then, the mounting base 3 is fixed in the middle position of the base.

[0057] S2. Take out the monitoring body 1, stably support the monitoring column 101, align the humidity capsule 1043 at the lower end of the internal detection rod 104 with the drilled hole, and slowly lower it until the lower end of the monitoring column 101 is stably inserted into the mounting base 3, and use bolts to fix the mounting base 3 to the monitoring column 101.

[0058] S3. Power on the control unit 102, check and initialize the status of the light alarm component 103, pressure sensor 202 and laser detector 1046 and it is ready to use.
