Description

Technical Field

[0001] This utility model relates to the field of underground monitoring technology, and in particular to a horizontal underground monitoring device. Background Technology

[0002] Geological disasters refer to catastrophic events caused by natural and human-induced geological processes that damage the ecological environment or alter geological structures. Common geological disasters include earthquakes, landslides, debris flows, ground subsidence, ground fissures, collapses, and coal and rock explosions. They occur suddenly, move rapidly, and have immense impact force, capable of instantly destroying bridge piers, houses, and roadbeds. They seriously threaten the lives and property of people in mountainous areas, water conservancy and hydropower projects, main highways (railways), oil and gas pipelines, and the general public, and damage the ecological environment of mountainous areas, causing enormous disasters worldwide.

[0003] Currently, to reduce losses caused by geological disasters, real-time displacement monitoring is conducted. Existing methods for monitoring deep displacement in geological disasters include the marker method, ground measurement method, and borehole tilting method. These methods infer the displacement of geological bodies by measuring their data. However, existing methods cannot monitor the displacement of geological disasters in real time; data can only be obtained through periodic measurements. This can lead to missing rapid displacements that occur within a short period. Furthermore, existing monitoring methods require significant manpower and resources for large-scale monitoring, resulting in low monitoring efficiency. Summary of the Invention

[0004] This utility model provides a horizontal underground monitoring device that can monitor in real time environments prone to geological disasters, such as coal mines, roadways, tunnels, dams, permafrost layers, landslides, debris flows, and earthquake fault zones. It provides specific data on underground geological changes and can provide the national earthquake monitoring network with first-hand data on stress changes in the longitude and latitude directions deep below the monitoring device's location. The specific technical solution is as follows:

[0005] A horizontal underground monitoring device is characterized by comprising four sensors connected by end caps to form a cylindrical structure. Each sensor has an internal cavity, and one end of each sensor has a liquid inlet communicating with the cavity. The liquid inlets are connected to a pressure control device via pressure transmission lines. The pressure control device is connected to a hydraulic pump of a hydraulic cylinder. Liquid is injected into the cavity of the sensor through the pressure transmission lines to maintain a base pressure. Each pressure transmission line is equipped with a pressure sensor to monitor the liquid pressure inside the sensor and send the pressure information to a data acquisition unit. The sensor also has a temperature sensor and a moisture sensor connected to the data acquisition unit via temperature and moisture signal lines, respectively. The temperature and moisture sensors monitor the temperature and moisture information of the formation. The formation temperature monitored by the temperature sensor can correct for pressure changes caused by temperature variations, making the output pressure signal more accurate.

[0006] Furthermore, there are two end caps, which are symmetrically installed at both ends of the four sensors, thereby connecting the four sensors together.

[0007] Furthermore, the sensors are approximately rugby ball-shaped, arranged symmetrically in pairs and connected by end caps.

[0008] Furthermore, the pressure sensor is connected to the data acquisition unit via a pressure signal line. When the outer wall of the sensor is squeezed by an external force, the liquid pressure inside the sensor cavity will change accordingly. Based on the pressure change of the liquid inside the sensor, the system analyzes whether a disaster will occur and the location of the disaster.

[0009] Furthermore, the injection port of the pressure control device is connected to the hydraulic pump of the hydraulic cylinder, and the outlet of the pressure control device is connected to the inlet of the sensor through a pressure transmission pipeline. The pressure control device is used to control the opening and closing of the pipeline and to regulate the supply pressure of the pipeline.

[0010] Furthermore, in the boreholes of the formations that require monitoring, the monitor is installed along the axis of the borehole to a deep distance in the formation. The gap between the monitor and the borehole is solidified by grouting material, which tightly couples the monitor with the formation. The monitor receives stress change data in the longitudinal and latitudinal directions from the borehole at a deep distance in the formation through the sensor.

[0011] Furthermore, the data acquisition device includes a housing, a circuit board disposed inside the housing, and a touch screen disposed on the surface of the housing. The circuit board is provided with a microprocessor, an A / D conversion module, a storage module, a display module, and a wireless network communication module. The A / D conversion module, storage module, display module, and wireless network communication module are respectively connected to the microprocessor via wires, and the display module is connected to the touch screen.

[0012] There are 12 A / D conversion modules, which operate independently. Each A / D conversion module independently acquires a sensor signal from one channel, converts it into a digital signal, and transmits it to the microprocessor for processing. The storage module stores the signals processed by the microprocessor, and the records in the storage module can be retrieved and displayed through the touch screen. The wireless network communication module can connect and send the signals processed by the microprocessor to external devices.

[0013] Furthermore, a power supply, which is a lithium battery, is also installed inside the casing. The power supply is connected to the microprocessor and provides power to the various units on the circuit board through the microprocessor.

[0014] This invention uses sensors to monitor stress changes in the longitudinal and latitudinal directions deep beneath the location of the monitoring device. It provides real-time monitoring of environments prone to geological disasters, such as coal mines, roadways, tunnels, dams, permafrost, landslides, debris flows, and earthquake fault zones, offering detailed data on underground geological changes. It can also provide the national earthquake monitoring network with firsthand data on stress changes in the longitudinal and latitudinal directions deep beneath the monitoring device's location.

[0020] To better understand the purpose, function, and specific design of this utility model, the horizontal underground monitoring device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, the horizontal underground monitoring device of this utility model includes four sensors 11 connected by end caps 15 to form a cylindrical structure. Each sensor 11 has an internal cavity. One end of each sensor 11 has a liquid inlet 14 that communicates with the cavity. The liquid inlet 14 is connected to a pressure control device 3 via a pressure transmission pipeline 7. The pressure control device 3 is connected to a hydraulic pump of a hydraulic cylinder. Liquid is injected into the cavity of the sensor 11 through the pressure transmission pipeline 7 to maintain a base pressure. Each pressure transmission pipeline 7 is equipped with a pressure sensor 2 to monitor the liquid pressure inside the sensor 11 and send the pressure information to a data acquisition device 4. The sensor 11 is also equipped with a temperature sensor 12 and a moisture sensor 13. The temperature sensor 12 and moisture sensor 13 are connected to the data acquisition unit 4 via temperature signal line 5 and moisture signal line 6, respectively. The temperature sensor 12 and moisture sensor 13 are used to monitor the temperature and moisture information of the formation. The formation temperature monitored by the temperature sensor 12 can correct for pressure changes caused by temperature variations, making the output pressure signal more accurate. When used in coal mines, underground tunnels, and roadways, the moisture sensor 13 can provide early warning of water inrush accidents when the groundwater level rises.

[0022] Specifically, such as Figures 2-4 As shown, there are two end caps 15, which are symmetrically installed at both ends of the four sensors 11, thereby connecting the four sensors 11 together.

[0023] The sensors 11 are approximately rugby ball-shaped, arranged symmetrically in pairs and connected by end caps 15.

[0024] like Figures 1-4 As shown, the pressure sensor 2 is connected to the data acquisition unit 4 through the pressure signal line 8. When the outer wall of the sensor 11 is squeezed by an external force, the liquid pressure in the cavity of the sensor will change accordingly. Based on the pressure change of the liquid in the sensor 11, the system analyzes whether a disaster will occur and the location of the disaster.

[0025] The injection port of the pressure control device 3 is connected to the hydraulic pump of the hydraulic cylinder, and the outlet of the pressure control device 3 is connected to the inlet 14 of the sensor 11 through the pressure transmission pipeline 7. The pressure control device 3 is used to control the opening and closing of the pipeline 7 and to adjust the supply pressure of the pipeline 7.

[0026] like Figure 5 As shown, the data acquisition device 4 includes a housing, a circuit board disposed inside the housing, and a touch screen disposed on the surface of the housing. The circuit board is provided with a microprocessor, an A / D conversion module, a storage module, a display module, and a wireless network communication module. The A / D conversion module, the storage module, the display module, and the wireless network communication module are respectively connected to the microprocessor through wires, and the display module is connected to the touch screen.

[0027] The system comprises 12 A / D conversion modules. Four A / D conversion modules are connected to four pressure sensors, four to four temperature sensors, and four to four moisture sensors. These 12 modules operate independently, acquiring signals from their respective sensors, converting them into digital signals, and transmitting them to the microprocessor for processing. A storage module stores the processed signals, which can be retrieved and displayed via a touchscreen. A wireless network communication module connects and transmits the processed signals to external devices, such as mobile phones or computers.

[0028] The housing also houses a power supply, which is a lithium battery. The power supply is connected to the microprocessor and provides power to the various units on the circuit board through the microprocessor.

[0029] In use, a borehole is drilled in the stratum requiring monitoring. The monitor is installed along the borehole axis to a deep depth within the stratum. The gap between the monitor and the borehole is filled with grout to ensure tight coupling between the monitor and the stratum. Liquid is injected into the sensor body through a pressure transmission pipeline. After on-site debugging, the base pressure values ​​of the four sensors are made completely consistent. The sensors receive stress change data in the longitudinal and latitudinal directions from the borehole deep within the stratum. When the geological pressure changes, the outer wall of the sensor body 11 is compressed by external force, causing the liquid pressure inside the sensor body cavity to change accordingly. Based on the different pressure values ​​generated by the four sensors, the data acquisition unit can accurately determine the direction and angle of the disaster and take timely action.

[0030] This underground monitoring device uses four sensors to monitor stress changes in the longitude and latitude directions deep below the monitoring device's location. It can monitor in real time environments prone to geological disasters, such as coal mines, roadways, tunnels, dams, permafrost, landslides, debris flows, and earthquake fault zones, providing specific data on underground geological changes. It can also provide the national earthquake monitoring network with first-hand data on stress changes in the longitude and latitude directions deep below the monitoring device's location.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
