Description

Technical Field

[0001] This utility model relates to the field of earthquake surveying technology, and in particular to an adsorption and fixing device for seismic wave detectors. Background Technology

[0002] Seismic wave methods are a commonly used forecasting method for advanced geological prediction of tunnels. Seismic detectors are used to receive and record vibration signals to predict the geological conditions ahead of tunnel excavation. Due to differences in strata properties, the vibration energy, i.e., the vibration, propagates within the surrounding rock after the excitation source is activated. When it encounters a wave impedance interface (usually faults and fracture zones have wave impedance interfaces), the vibration is reflected or diffracted. These reflected and diffracted vibration signals are recorded by the seismic detector, and the recorded seismic wave signals are used to invert the presence of fault fracture zones, etc., in the surrounding rock.

[0003] Currently, within the TBM tunnel section, the limited space and the fact that most of the space is occupied by mechanical equipment make it difficult and inefficient to install in-hole geophones after drilling, which to some extent affects the normal construction of the TBM. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adsorption and fixing device for seismic wave detectors, in view of the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: an adsorption and fixing device for a seismic wave detector, comprising:

[0006] Mounting base, placed on the seismic wave detector;

[0007] Magnetic components, embedded in the inner bottom of the mounting base, are used to attract the steel arch frame inside the tunnel;

[0008] The locking element, located on the mounting base, is used to lock and fix the mounting base to the steel arch frame inside the tunnel.

[0009] Through the aforementioned technical means, the use of magnetic components allows the mounting base to be adapted to metal structural surfaces of different shapes, especially steel arch structures inside tunnels. This allows the seismic detector to be flexibly adjusted in position. The magnetic adsorption method also facilitates the installation and disassembly of the seismic detector. The locking components further reinforce the connection between the mounting base and the steel arch on the basis of magnetic adsorption, ensuring stability even in a vibration environment. This enables the seismic detector to accurately record vibration signals.

[0010] In some embodiments, the locking element includes a threaded hole and a bolt. The mounting base and the steel arch frame are provided with corresponding threaded holes. The bolt is threadedly engaged with the threaded hole to fix the mounting base to the steel arch frame.

[0011] In some embodiments, the diameter of the threaded hole and the diameter of the bolt are both M8.

[0012] In some embodiments, the magnetic component is a powerful permanent magnet.

[0013] In some embodiments, the powerful permanent magnet is made of neodymium iron boron with a nickel-plated surface and a magnetic attraction force ≥200N.

[0014] In some embodiments, the mounting base is made of high-strength aluminum alloy.

[0015] In some embodiments, the high-strength aluminum alloy is 6061-T6 aluminum alloy.

[0016] The beneficial effects of this utility model are:

[0017] 1. Utilizing the magnetic attraction of the magnetic components, the mounting base can be firmly adsorbed onto the magnetic materials (steel arch or metal support structure) inside the tunnel. This magnetic adsorption connection method not only allows for quick installation but also facilitates adjustment of the installation position and angle. Simultaneously, threaded holes and bolts further tighten the mounting base and magnetic material, creating a dual locking mechanism for the seismic detector. This ensures high stability even in environments with strong vibrations, reducing movement that could affect the accuracy of data acquisition. Thus, while ensuring normal TBM construction, it enables efficient installation of seismic detectors and efficient acquisition of vibration signals within the TBM tunnel section. Signal collection provides feedback on geological conditions, enabling advanced geological prediction. Compared to methods such as buried drilling and advanced horizontal core drilling for advanced geological conditions, the magnetic adsorption method is more convenient, faster, requires less investment, facilitates construction, reduces overlap time in advanced geological drilling and core drilling, and improves work efficiency.

The use of the phrase "in one embodiment" or "in an embodiment" does not necessarily refer to the same embodiment. Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

[0022] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps. Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0024] Combination Figure 1 As shown, this embodiment is an adsorption and fixing device for a seismic wave detector, including a mounting base 1, a magnetic component, and a locking component 2. The top of the mounting base 1 can be connected to the seismic wave detector. A magnetic component is embedded in the inner bottom of the mounting base 1. The magnetic component is used to adsorb the mounting base 1 onto magnetic materials such as steel arch frames and metal support structures in the tunnel. The mounting base 1 is provided with a locking component 2, which is used to lock and fix the mounting base 1 to the magnetic material.

[0025] In some implementations, the mounting base 1 has a cylindrical structure, and the middle part of the mounting base 1 has a hollowed-out part with a regular hexagonal structure.

[0026] Furthermore, the mounting base 1 is made of high-strength aluminum alloy. Specifically, in this embodiment, the high-strength aluminum alloy is 6061-T6 aluminum alloy.

[0027] The installation base 1 is made of high-strength aluminum alloy, which enhances the durability of the device and supports multiple reuses. The aluminum alloy material used is 6061-T6 high-strength aluminum alloy, which ensures structural strength while reducing the overall weight. At the same time, it can continuously detect the current location and the geological conditions of the tunnel ahead, and form an interconnection with the buried points ahead, so as to make predictions on the geological conditions ahead from multiple directions and angles.

[0028] In some embodiments, the locking element 2 includes a threaded hole and a bolt. The side wall of the mounting base 1 and the steel arch frame are provided with corresponding threaded holes. The bolt is threadedly engaged with the threaded hole to fix the mounting base 1 to the magnetic material.

[0029] Furthermore, the diameter of the threaded hole and the diameter of the bolt are both M8. Specifically, in this embodiment, the tightening torque of the bolt and the threaded hole is 5-8 N·m.

[0030] Furthermore, the magnetic component uses a powerful permanent magnet. Specifically, in this embodiment, the powerful permanent magnet is made of neodymium iron boron and its surface is plated with nickel. The magnetic attraction force of the powerful permanent magnet is ≥200N.

[0031] By using powerful permanent magnets with large magnetic attraction, the mounting base 1 can be quickly attracted to the steel arch frame inside the tunnel. The neodymium iron boron permanent magnets ensure strong attraction, and the nickel plating treatment on the surface can improve corrosion resistance and service life.

[0032] The implementation principle of an adsorption fixing device for a seismic wave detector is as follows:

[0033] A powerful permanent magnet can quickly and firmly attach the mounting base 1 to the steel arch frame inside the tunnel, reducing installation time to within 10 seconds. Threaded holes and bolts further tighten the mounting base 1 and the steel arch frame, ensuring high stability even in environments with strong vibrations. After tightening, the overall vibration resistance is ≥8, capable of withstanding the vibration and impact generated during TBM excavation, reducing potential movement that could affect data acquisition accuracy, and improving the signal-to-noise ratio by 30%. Furthermore, replacing the mounting base 1 takes less than 15 seconds, and the overall thickness is ≤50mm, improving adaptability to the confined installation space within the tunnel. This not only solves the problem of difficult installation of seismic detectors in TBM sections but also significantly improves installation efficiency, data acquisition accuracy and stability, while ensuring structural safety and equipment reusability. It accelerates advanced geological prediction detection and improves the accuracy and timeliness of advanced geological exploration.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
