Abstract
Description
Technical Field
[0001] This utility model relates to the field of seismograph technology, specifically to a traceable buried seismograph and its components. Background Technology
[0002] In the field of earthquake monitoring, buried seismographs are widely used for long-term, concealed seismic motion data acquisition. Traditional seismographs are usually buried directly underground. While they have advantages in terms of anti-interference and environmental adaptability, they also present challenges in retrieval. Due to the deep burial location and changing surface environment, subsequent positioning relies mainly on manual marking or memory, making it highly susceptible to location information loss due to natural or human factors. This results in equipment that is difficult to find or has extremely high recovery costs. Furthermore, conventional buried seismographs are prone to settlement or displacement in soft soil or loose geological conditions, affecting data quality and equipment stability.
[0003] Therefore, there is an urgent need for a buried seismograph that can achieve efficient and accurate positioning and reliable geological anchoring, effectively improving the recall, data quality and long-term stability of the seismograph after it is buried without significantly increasing the system complexity and cost. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems by providing a traceable buried seismograph and its components. Through a separately configured identifiable beacon unit, the tracer beacon is connected to the protective cabin via a beacon connection. Furthermore, the buried position is closer to the ground surface than the seismograph body, which significantly reduces the signal attenuation caused by the strata and greatly improves the detectability and identification efficiency of the tracer beacon. This effectively solves the technical problem of difficult retrieval and positioning of buried seismographs.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A traceable buried seismograph includes a protective cabin, a seismograph body, and an identifiable beacon unit. The beacon unit includes a tracer beacon, a beacon mounting base, and a beacon connection part. One end of the beacon connection part is connected to the protective cabin, and the other end is connected to the beacon mounting base. The tracer beacon is mounted on the beacon mounting base. When the protective cabin is buried underground, the buried position of the tracer beacon is closer to the ground surface than the seismograph body.
[0007] Thanks to the above technical solution, the tracer beacon is connected to the protective cabin through the beacon connector and is buried closer to the ground surface, reducing the shielding and attenuation of the signal by the strata. This makes the tracer beacon easier to be identified by remote detection devices, thus solving the problem of difficult positioning when the seismograph is retrieved and improving the equipment recallability and operational efficiency.
[0008] Furthermore, the protective cabin is provided with an installation groove on its upper ring, and an expansion bladder is provided in the installation groove. When the expansion bladder is inflated, it protrudes outward from the surface of the protective cabin.
[0009] Thanks to the above technical solution, the expansion bladder protrudes outward from the surface of the protective chamber when it expands, allowing it to bond tightly with the surrounding geology, increasing friction and anchoring force, preventing the seismograph from settling or shifting in soft soil or loose geology, and improving equipment stability and data acquisition quality.
[0010] Furthermore, the inflatable bladder is an air bladder or a liquid bladder.
[0011] Thanks to the above technical solution, expansion can be achieved through air or liquid filling, which is easy to operate and adaptable to different geological conditions, providing a reliable anchoring effect while reducing deployment complexity.
[0012] Furthermore, multiple mounting slots are arranged radially at intervals along the protective chamber, and each mounting slot is equipped with an expansion bladder.
[0013] Thanks to the aforementioned technical solution, multiple expansion bladders are arranged radially and spaced along the protective chamber, providing uniform anchoring force, avoiding stress concentration at single points, and enhancing the overall stability and adaptability of the equipment after burial, especially in uneven geological conditions. It also prevents the protective chamber from becoming unstable due to the failure of a single expansion bladder caused by geological movement or insect corrosion in the burial environment.
[0014] Furthermore, the beacon connection part is a flexible connecting chain or a flexible connecting rope.
[0015] Thanks to the above technical solution, the beacon connection uses a flexible connecting chain or flexible connecting rope, which allows the tracer beacon to be positioned naturally during the burial process, reducing mechanical damage to the beacon. At the same time, the flexible connection facilitates deployment and retrieval operations.
[0016] Furthermore, the tracking beacon is an RFID tag.
[0017] Thanks to the above technical solution, the tracer beacon uses RFID tags, which can achieve non-contact detection through radio frequency identification. It is easy to operate, has a long detection distance and high accuracy, is suitable for various environmental conditions, and improves the reliability of positioning.
[0018] Furthermore, the tracer beacon is a permanent magnet with high magnetic permeability.
[0019] Thanks to the above technical solution, the tracer beacon uses a permanent magnet with high magnetic permeability, which can generate a strong magnetic field signal that can be identified by the detection device. It has strong anti-interference ability and ensures the stability of the detection.
[0020] Furthermore, the protective cabin is equipped with a handle on its top.
[0021] Thanks to the adoption of the above technical solutions, the top of the protective cabin is equipped with a handle, which facilitates manual or mechanical grabbing, simplifies the deployment and recovery process of the equipment, and improves operational efficiency and ergonomics.
[0022] Furthermore, the protective cabin is equipped with an inclinometer, which can be connected to the control device via signal communication.
[0023] Thanks to the above technical solution, the inclinometer can monitor the tilt angle of the protective cabin and transmit the signal to the control device, enabling operators to understand the equipment's installation status in real time and ensuring the smooth installation of the traceable buried seismograph.
[0024] Thanks to the above technical solutions, the detection device can remotely identify tracer beacons and quickly locate the seismograph. The entire component provides a complete positioning and detection solution, greatly improving the seismograph's recovery efficiency, accuracy, and ease of operation.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0026] By setting up identifiable beacon units and placing the tracer beacons closer to the ground surface relative to the seismograph body, the detectability and retrieval efficiency of the equipment are significantly improved. An expansion bladder is installed in the mounting groove encircling the protective cabin; when inflated, it protrudes outward from the cabin surface, enhancing the bond with the surrounding geology and effectively preventing equipment settlement or displacement. Multiple expansion bladders are arranged radially and spaced along the protective cabin, further improving anchoring stability and reliability. The beacon connection uses a flexible connecting chain or rope, facilitating deployment and protecting the tracer beacon. The tracer beacon uses RFID tags or high-permeability permanent magnets, providing multiple reliable detection methods. An inclinometer installed inside the protective cabin monitors the equipment's attitude, ensuring that the orientation during installation meets requirements, thereby improving data acquisition quality. The overall solution significantly improves the positioning accuracy, long-term stability, and operational convenience of the buried seismograph. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings.
[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] Example 1
[0033] A traceable buried seismograph, such as Figure 1 As shown, the system includes a protective cabin 10, a seismograph body, and an identifiable beacon unit 20. The beacon unit 20 includes a tracer beacon 22, a beacon mounting base, and a beacon connection part 21. One end of the beacon connection part 21 is connected to the protective cabin 10, and the other end is connected to the beacon mounting base. The tracer beacon 22 is mounted on the beacon mounting base. When the protective cabin 10 is buried underground, the burial position of the tracer beacon 22 is closer to the ground surface than the seismograph body. Specifically, the tracer beacon 22 is connected to the protective cabin 10 through the beacon connection part 21, and its burial position is closer to the ground surface, reducing the shielding and attenuation of signals by the strata. This makes the tracer beacon 22 easier to be identified by the remote detection device 40, thereby solving the problem of difficult positioning during seismograph retrieval and improving equipment recall and operational efficiency.
[0034] The protective chamber 10 is provided with a mounting groove 11, and an expansion bladder 111 is provided inside the mounting groove 11. When the expansion bladder 111 expands, it protrudes outward from the surface of the protective chamber 10. Specifically, when the expansion bladder 111 expands outward from the surface of the protective chamber 10, it can tightly bond with the surrounding geology, increase friction and anchoring force, prevent the seismograph from settling or shifting in soft soil or loose geology, and improve the stability of the equipment and the quality of data acquisition.
[0035] The expansion bladder 111 is an air bladder. Specifically, it can be inflated by filling with liquid, which is easy to operate and adaptable to different geological conditions, providing a reliable anchoring effect while reducing deployment complexity.
[0036] Two mounting slots 11 are radially spaced along the protective chamber 10, and each mounting slot 11 contains an expansion bladder 111. Specifically, the radially spaced arrangement of the two expansion bladders 111 provides uniform anchoring force, avoids stress concentration at single points, and enhances the overall stability and adaptability of the equipment after burial, especially in uneven geological conditions. It also prevents the protective chamber 10 from becoming unstable due to the failure of a single expansion bladder 111 caused by geological movement or insect corrosion in the burial environment. In other embodiments, the number and spacing of the mounting slots 11 can be optimized according to the size of the protective chamber 10 and the expected load, for example, by adding more mounting slots 11 to enhance stability under extreme geological conditions.
[0037] The beacon connection 21 is a flexible connecting chain or a flexible connecting rope. Specifically, the beacon connection 21 uses a flexible connecting chain or a flexible connecting rope, which allows the tracer beacon 22 to be naturally positioned during the burial process, reducing mechanical damage to the beacon. At the same time, the flexible connection facilitates deployment and retrieval operations and adapts to different burial depths and terrains.
[0038] The tracer beacon 22 is an RFID tag. Specifically, the tracer beacon 22 uses an RFID tag, which can achieve non-contact detection through radio frequency identification. It is easy to operate, has a long detection range and high accuracy, is suitable for various environmental conditions, and improves positioning reliability. RFID has advantages in terms of power consumption and cost, making it suitable for long-term buried applications.
[0039] The protective compartment 10 is equipped with a handle 30 on its top. Specifically, the handle 30 on the top of the protective compartment 10 facilitates manual or mechanical gripping, simplifies the deployment and retrieval process of the equipment, and improves operational efficiency and ergonomics. In other embodiments, the handle 30 may be designed to be foldable or detachable to save space and facilitate transportation while maintaining gripping functionality.
[0040] The protective chamber 10 is equipped with an inclinometer, which can be signal-communicated with a control device. Specifically, the inclinometer monitors the tilt angle of the protective chamber 10 and transmits the signal to the control device, enabling operators to monitor the equipment's installation status in real time and ensuring the stable installation of the traceable buried seismograph. In other embodiments, the inclinometer can be integrated with other sensors, such as gyroscopes, to provide more comprehensive attitude data and facilitate information exchange via wireless transmission.
[0041] Example 2
[0042] Example 2 replaces the inflatable bladder 111 in Example 1 and is a replacement for Example 1; further explanation is needed, identical components will not be described again here, such as... Figure 1 As shown, the expansion bladder 111 is a liquid bladder. The core advantage of a liquid bladder lies in its ability to provide extremely stable and rigid support by utilizing the almost incompressible property of liquids. This is crucial for scenarios that require resisting continuous, strong, and directional lateral pressure from soil layers or preventing micro-displacement of equipment in vibrating environments.
[0043] Example 3
[0044] Example 3 replaces the tracer beacon 22 in Example 1, and is a replacement for Example 1; further explanation is needed, identical components will not be described again here, the tracer beacon 22 is a permanent magnet with high magnetic permeability. Specifically, the tracer beacon 22 uses a permanent magnet with high magnetic permeability, which can generate a strong magnetic field signal that can be identified by the detection device 40, has strong anti-interference ability, and ensures the stability of detection.
[0045] Example 4
[0046] A traceable embedded seismograph assembly, such as Figure 2 As shown, the system includes a traceable buried seismograph as provided in Embodiment 1, and a detection device 40 for remotely detecting the tracer beacon 22. Specifically, the detection device 40 can remotely identify the tracer beacon 22 and quickly locate the seismograph.
