Description

Technical Field

[0001] This utility model relates to the technical field of earthquake motion amplification effect monitoring devices, and in particular to an earthquake motion amplification effect monitoring device for basin sedimentary layers. Background Technology

[0002] The seismic amplification effect refers to the significant differences in the intensity of ground motion at different sites under the same seismic wave input. Widely distributed basin sedimentary layers, due to their deep soil layers, complex geological structures, and low shear wave velocities, are prone to reflection, refraction, and resonance of incident seismic waves (especially long-period components) during earthquakes, leading to amplification of surface ground motion intensity, particularly for long-period components. This amplification effect not only subjects buildings (especially high-rise and super high-rise buildings) to greater seismic loads, increasing the risk of damage, but can also trigger serious secondary disasters such as site liquefaction and foundation failure, posing a severe seismic safety threat to densely populated and economically developed basin areas. Therefore, accurately understanding the seismic amplification effect of basin sedimentary layers is crucial for scientifically assessing regional seismic risk, optimizing seismic fortification standards, and guiding urban planning and the site selection and design of major projects; it is fundamental to ensuring regional seismic safety.

[0003] In existing technologies, most devices for monitoring the amplification effect of ground motion in basin sedimentary layers often rely on gravity or shallow anchoring. In soft sedimentary layers, these devices are unable to resist the displacement caused by earthquakes, leading to sensor position shifts or even failure. This results in distorted ground motion data and seriously affects the accuracy of site effect analysis.

[0004] Therefore, those skilled in the art have provided a device for monitoring the amplification effect of ground motion in basin sedimentary layers to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a monitoring device for the amplification effect of seismic motion in basin sedimentary layers. This device uses a fixed cone and a fixed plate that extend underground, and a threaded rod and a rotating rod that drive the fixed teeth and the transverse fixed block to compress the soil, forming a strong gripping force and achieving multi-directional stable anchoring. This significantly enhances its stability in soft or complex sedimentary layers, effectively resists seismic displacement and overturning, ensures the monitoring equipment is firmly positioned, and continuously and accurately collects data, thereby improving the reliability and accuracy of seismic motion monitoring data.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for monitoring the amplification effect of seismic motion in a basin sedimentary layer includes a housing. A fixed cone is fixedly connected to the lower middle part of the housing. A first servo motor is installed inside the upper part of the fixed cone. A threaded rod is fixedly connected to the output end of the first servo motor. A threaded cylinder is threaded to the lower outer end of the threaded rod. Connecting rods are rotatably connected to multiple end faces of the threaded cylinder. Fixed teeth are rotatably connected to the other ends of the multiple connecting rods. Multiple fixed plates are fixedly connected to the lower outer side of the housing. Rotating rods are rotatably connected to both sides of the multiple fixed plates. Multiple transverse fixing blocks are rotatably connected to the outside of the multiple rotating rods. Multiple anti-slip particles are fixedly connected to both end faces of the multiple transverse fixing blocks. A controller, a battery, a seismic sensor, and a wireless communication module are installed inside the lower part of the housing.

[0008] Through the above technical solution, the device extends into the ground through a fixed cone and a fixed plate. The threaded rod and rotating rod drive the fixed teeth and the transverse fixed block to squeeze the soil, forming a strong gripping force and achieving multi-directional stable anchoring. This significantly enhances its stability in soft or complex sedimentary layers, effectively resists seismic displacement and overturning, ensures that the monitoring equipment is firmly positioned, and continuously and accurately collects data, thereby improving the reliability and accuracy of seismic ground motion monitoring data.

[0009] Furthermore, a third servo motor is provided at the upper end of the interior of the housing, and a gear is sleeved on the output end of the third servo motor. A gear ring is meshed with one side of the gear, and a bracket is fixedly connected to the upper end of the gear ring. A solar panel is provided at the upper end of the bracket.

[0010] Through the above technical solution, the third servo motor drives the gear and the ring gear to rotate, thereby enabling automatic tracking of the sun, maximizing the solar energy collection efficiency, providing stable and clean energy for the device, and reducing dependence on external power supply.

[0011] Furthermore, a guide ring is fixedly connected to the outside of the toothed ring, and the guide ring is located inside the housing and the two are rotatably connected;

[0012] Through the above technical solution, a guide ring is set on the outside of the gear ring and rotates and connects with the inside of the housing, providing a stable and low-friction track for the rotation of the gear ring, ensuring the smoothness and accuracy of the rotation of the solar panel driven by the third servo motor.

[0013] Furthermore, the lower ends of the plurality of fixed teeth are all located inside the fixed cone and the two are rotatably connected by a rotating shaft;

[0014] Through the above technical solution, the fixed tooth is rotatably connected to the fixed cone through the rotating shaft, so that the fixed tooth can be flexibly and reliably tilted under the drive of the threaded rod, better adapting to different soil conditions, optimizing the squeezing effect, enhancing the adaptability and initial anchoring force of the anchoring, and improving the stability of the device in complex geological environments.

[0015] Furthermore, pulleys are fitted on the upper outer sides of the upper ends of the plurality of rotating rods, and toothed belts are fitted on the outer sides of each pair of the plurality of pulleys. A second servo motor is connected to the upper end of one of the two rotating rods inside the plurality of fixed plates.

[0016] Through the above technical solution, a second servo motor is used to synchronously drive multiple rotating rods through pulleys and toothed belts, thereby achieving precise and synchronous control of the rotation of multiple transverse fixed blocks. This ensures that each transverse fixed block can consistently and reliably compress the soil, enhancing the uniformity of the device's anchoring and overall stability.

[0017] Furthermore, the interior of the plurality of fixing plates is provided with a plurality of grooves, and the plurality of transverse fixing blocks are all located inside the grooves;

[0018] The above technical solution provides a clear placement space for the horizontal fixing block, ensuring positional stability. At the same time, it accommodates and releases lateral force when pulled out, reducing resistance and making recovery smoother and safer.

[0019] Furthermore, handles are fixedly connected to both end faces of the housing;

[0020] The above technical solution, with handles on both sides of the casing, greatly facilitates the handling, installation, and on-site operation of the device, reduces labor costs and operational difficulty, and enables staff to deploy and maintain the monitoring device more easily and safely, thereby improving work efficiency and the convenience of on-site operations.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a monitoring device for the amplification effect of seismic motion in basin sedimentary layers. The device first extends into the ground through a fixed cone and a fixed plate, and then the rotation of the threaded rod drives the connecting rod to tilt the fixed teeth. At the same time, the rotating rod drives the transverse fixed block to rotate, so that the fixed teeth and the transverse fixed block can squeeze the surrounding soil more deeply and widely, forming a strong gripping force and achieving multi-directional stable anchoring. This significantly enhances the stability of the device in soft or complex sedimentary layers, effectively resists displacement and overturning caused by seismic motion, and ensures that the monitoring equipment can still be firmly positioned during an earthquake, continuously and accurately collecting seismic motion data, effectively improving the reliability and accuracy of seismic motion monitoring data.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1-5This utility model provides a specific embodiment: a monitoring device for the amplification effect of seismic motion in a basin sedimentary layer, including a housing 1, a fixed cone 2 fixedly connected to the lower middle part of the housing 1, a first servo motor 3 provided inside the upper part of the fixed cone 2, a threaded rod 4 fixedly connected to the output end of the first servo motor 3, a threaded cylinder 5 threaded to the lower part of the threaded rod 4, connecting rods 6 rotatably connected to multiple end faces of the threaded cylinder 5, and fixed teeth 7 rotatably connected to the other end of multiple connecting rods 6, multiple fixed plates 8 fixedly connected to the lower outer side of the housing 1, rotating rods 9 rotatably connected to both sides of the interior of multiple fixed plates 8, multiple transverse fixed blocks 10 rotatably connected to the exterior of multiple rotating rods 9, and multiple anti-slip particles 11 fixedly connected to both end faces of multiple transverse fixed blocks 10, and a controller 21, a battery 22, a seismic sensor 23 and a wireless communication module 24 provided inside the lower part of the housing 1;

[0032] Through the above technical solution, the device extends into the ground through the fixed cone 2 and the fixed plate 8. The threaded rod 4 and the rotating rod 9 drive the fixed teeth 7 and the transverse fixed block 10 to squeeze the soil, forming a strong gripping force and achieving multi-directional stable anchoring. This significantly enhances its stability in soft or complex sedimentary layers, effectively resists seismic displacement and overturning, ensures that the monitoring equipment is firmly positioned, and continuously and accurately collects data, thereby improving the reliability and accuracy of seismic ground motion monitoring data.

[0033] A third servo motor 15 is installed at the upper part of the interior of the housing 1. A gear 16 is fitted onto the output end of the third servo motor 15. A gear ring 17 is meshed with one side of the gear 16. A bracket 18 is fixedly connected to the upper end of the gear ring 17. A solar panel 19 is installed at the upper end of the bracket 18. The third servo motor 15 drives the gear 16 to mesh with the gear ring 17, causing the bracket 18 and the solar panel 19 to rotate. This enables automatic tracking of the sun, maximizes the solar energy collection efficiency, provides a stable and clean energy source for the device, and reduces dependence on external power supply. A guide ring 20 is fixedly connected to the outside of the gear ring 17. The guide ring 20 is located inside the housing 1 and the two are rotatably connected. The guide ring 20 is set on the outside of the toothed ring 17 and is rotatably connected to the inside of the housing 1, providing a stable and low-friction track for the rotation of the toothed ring 17, ensuring the smoothness and accuracy of the rotation of the solar panel 19 driven by the third servo motor 15. The lower ends of multiple fixed teeth 7 are all located inside the fixed cone 2 and the two are rotatably connected by a rotating shaft. The fixed teeth 7 are rotatably connected to the fixed cone 2 by the rotating shaft, so that the fixed teeth 7 can be flexibly and reliably tilted under the drive of the threaded rod 4, better adapting to different soil conditions, optimizing the squeezing effect, and enhancing the anchoring suitability. The adaptability and initial anchoring force improve the stability of the device in complex geological environments. Each of the upper ends of multiple rotating rods 9 is fitted with a pulley 12, and toothed belts 13 are fitted between each pair of pulleys 12.

The second servo motor 14 synchronously drives the multiple rotating rods 9 through the pulleys 12 and toothed belts 13, achieving precise and synchronous control of the rotation of multiple transverse fixing blocks 10. This ensures that each transverse fixing block 10 can consistently and reliably compress the soil, enhancing the uniformity and overall stability of the device's anchoring. Qualitatively, multiple grooves are provided inside the multiple fixing plates 8, and multiple transverse fixing blocks 10 are located inside the grooves, providing clear placement space for the transverse fixing blocks 10, ensuring positional stability, and accommodating the release of transverse force when pulled out, reducing resistance, and making recovery smoother and safer. Handles 25 are fixedly connected to both ends of the housing 1. The addition of handles 25 on both sides of the housing 1 greatly facilitates the handling, installation and on-site operation of the device, reduces labor costs and operational difficulty, and enables staff to deploy and maintain the monitoring device more easily and safely, improving work efficiency and on-site operation convenience.

[0034] Working Principle: When the device is in operation, the worker first inserts the fixing cone 2 and the fixing plate 8 into the ground. Then, the first servo motor 3 drives the threaded rod 4 to rotate, causing the connecting rod 6 to tilt the fixing teeth 7; simultaneously, the second servo motor 14 drives the rotating rod 9, which in turn drives the transverse fixing block 10 to rotate. This allows the two to compress the surrounding soil more deeply and widely, forming strong friction and interlocking forces within the soil, achieving multi-directional stable anchoring. This significantly enhances the stability of the device in soft or complex sedimentary layers, effectively resisting displacement and overturning caused by seismic vibrations, ensuring the monitoring equipment remains firmly positioned during vibrations, and continuously and accurately collecting seismic data, thereby effectively improving the reliability and accuracy of the monitoring data.
