Description

Technical Field

[0001] This utility model relates to the field of earthquake detection technology, and in particular to a strong earthquake accelerometer device that is easy to mount on the side. Background Technology

[0002] Broadband seismometers must not be dropped, inverted, or placed on their side during transportation, including by airplane, train, ship, or car. Because of their precise mechanical and electronic structure, they are not easily subjected to large vibrations and impacts and should be handled with care at all times. This leads to inconvenience in transportation. Therefore, this utility model designs a locking pendulum device for broadband seismometers.

[0003] In further research, the company designed an integrated seismic observation instrument that combines multiple functions such as accelerometer, acquisition, storage, data transmission, and detection. Internally, it comprises a 24-bit acquisition unit, an accelerometer, a data storage unit, network communication, and a timing unit.

[0004] The triaxial force-balanced accelerometer consists of three independently directional sensors (one vertical and two horizontal) integrated into a single unit, incorporating electronic feedback circuitry, control circuitry, and power conversion circuitry. The data acquisition unit collects the voltage signals output by the sensors, including three fully balanced differential channels with high resolution, wide dynamic range, and fast real-time data stream output. It also boasts extremely high timekeeping accuracy and incorporates a large-capacity, industrial-grade, wide-temperature-range memory, capable of recording continuous data, event data, and calibration data for extended periods. Data from multiple sampling rates can be simultaneously transmitted in real-time to the network center via the network.

[0005] However, further research revealed that it still has the problem of being inconvenient for side mounting; for example, the seismic observation instrument can only be used after being leveled on the ground, but when used in tunnels, it cannot be guaranteed that the internal positioning will be accurate when installed on a vertical wall, which in turn affects the accuracy of stress changes and vibrations in the geological layers of the mountain where the tunnel is located. Utility Model Content

[0006] The side-mounted strong vibration accelerometer device provided in this embodiment solves the problem of inconvenience in side-mounting on the inner wall of a tunnel.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a side-mounted strong shock accelerometer device, including a mounting liner, a base plate, a base, a ring, and a top cover plate arranged sequentially from bottom to top; it also includes a three-axis force balance accelerometer, which is composed of three independently directional sensors, and the three-axis force balance accelerometer is mounted on the base.

[0009] The three-axis force balance accelerometer consists of three independent directional sensors (one vertical and two horizontal) integrated into one unit, with built-in electronic feedback circuit, control circuit, and power conversion circuit.

[0010] The mounting liner is made of metal steel plate; the base plate is used to adjust the distance between itself and the mounting liner, and the base plate is provided with multiple leveling bolts; the upper surface of the base is provided with a circular boss, which is sleeved with the ring and a positioning pin is provided between them.

[0011] The ring has a machined end face on its circumferential wall, and the base has two strip-shaped latches protruding from the bottom plane. The two latches extend perpendicularly and do not intersect. The end face is parallel to one of the strip-shaped latches on the bottom plane of the base. The right-angled area formed by the inner sides of the two strip-shaped latches is used to clamp and fix one independent directional sensor, and the outer sides of the two strip-shaped latches are used to clamp two other independent directional sensors respectively.

[0012] A basic instrument positioning plane is also provided on the peripheral wall of the circular boss on the upper surface of the base; the basic instrument positioning plane is perpendicular to the end plane on the ring sleeve.

[0013] Preferably, it also includes leveling screws; the leveling screws are detachably connected between the base plate and the base.

[0014] Preferably, the upper cover plate is provided with a handle; the handle is an arched handle.

[0015] Preferably, the upper cover plate is also provided with indicator lights, a display screen, a horizontal bubble window, an installation orientation marker, a GNSS socket, and a power network socket.

[0016] Preferably, the handle is an arched handle.

[0017] Preferably, the side-mounted strong vibration accelerometer device also includes an adjustable bottom corner screw and a bottom corner screw back nut; both are installed at the bottom of the mounting plate, and the two work together to achieve adjustment of the height of the mounting plate in the longitudinal direction.

[0018] Compared with the prior art, this utility model provides a strong shock accelerometer device that is easy to mount on the side, and has the following beneficial effects:

[0019] Analysis of the above technical solution reveals that this side-mounted strong-motion accelerometer device mainly consists of a mounting liner, a base plate, a base, a ring, and a top cover. The structural layout shows that the mounting liner, base plate, base, ring, and top cover are arranged sequentially from bottom to top. Internally, a three-dimensional force-balanced accelerometer is installed, consisting of three independently directional sensors, mounted on the base. The specific installation method is as follows: a machined end face is provided on the circumferential wall of the ring, and two protruding strip-shaped latches are provided on the bottom plane inside the base. The end face is parallel to one of the strip-shaped latches on the bottom plane inside the base. The right-angled area formed by the inner sides of the two strip-shaped latches is used to clamp and fix one independently directional sensor, while the outer sides of the two strip-shaped latches are used to clamp the other two independently directional sensors respectively. Because the bottom of the independent directional sensor is a very regular rectangular cross-section plane, the right-angle area formed by the inner sides of the two strip-shaped latches can be used to lock and fix one independent directional sensor. The outer sides of the other two strip-shaped latches respectively abut against the corresponding independent directional sensors, thus realizing the installation of three independent directional sensors. When the entire device needs to be installed on its side, the installation positions of the three independent directional sensors inside remain stable and will not deviate.

[0020] Meanwhile, after internal positioning and installation, the ring itself has a machined end face on its circumferential wall; and the end face is parallel to one of the strip-shaped latches on the bottom plane inside the base; so the direction can be quickly adjusted from the outside of the ring.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figures 1-5 As shown, Embodiment 1 of this utility model discloses a side-mounted strong shock accelerometer device, including a mounting liner 10, a base plate 20, a base 30, a ring 40, and an upper cover plate 50 arranged sequentially from bottom to top; it also includes a three-axis force balance accelerometer, which is composed of three independently directional sensors (not shown in the figure), and the three-axis force balance accelerometer is mounted on the base;

[0032] The mounting liner 10 is a metal steel plate; the base plate 20 is used to adjust the distance between itself and the mounting liner 10 (i.e., to achieve one-time leveling), and the base plate 20 is provided with multiple leveling bolts; the upper surface of the base 30 is provided with a circular boss, which is sleeved with the ring sleeve 40 and a positioning pin is provided between the two.

[0033] The ring 40 has a machined end face 60 on its circumferential wall, and the base has two strip-shaped latches 70 protruding from the bottom plane. The two latches extend perpendicularly and do not intersect. The end face is parallel to one of the strip-shaped latches on the bottom plane of the base. The right-angled area formed by the inner sides of the two strip-shaped latches 70 is used to clamp and fix one independent directional sensor, and the outer sides of the two strip-shaped latches 70 are used to clamp two other independent directional sensors respectively.

[0034] A basic instrument positioning plane 32 is also provided on the peripheral wall of the circular boss on the upper surface of the base 30; the basic instrument positioning plane 32 on the base 30 is perpendicular to the end plane 60 on the ring. See also Figure 1 , Figure 1 The instrument's basic positioning plane 32 is parallel to the Y-axis; see [link / reference]. Figure 2 , Figure 2 The end plane 60 is parallel to the X-axis.

[0035] Analysis of the above technical solution shows that the aforementioned side-mounted strong vibration accelerometer device mainly consists of a mounting liner, a base plate, a base, a ring, and a top cover plate. Analysis of its structural layout shows that the mounting liner, base plate, base, ring, and top cover plate are arranged sequentially from bottom to top. Simultaneously, a three-dimensional force balance accelerometer is installed inside, which consists of three independently directional sensors, and the three-dimensional force balance accelerometer is mounted on the base.

[0036] The specific installation method is as follows: A machined end face is provided on the circumferential wall of the ring, and two strip-shaped latches protruding from the bottom plane inside the base are provided. The end face is parallel to one of the strip-shaped latches on the bottom plane inside the base. The right-angled area formed by the inner sides of the two strip-shaped latches is used to clamp and fix one independent directional sensor, while the outer sides of the two strip-shaped latches are used to clamp and fix the other two independent directional sensors respectively. Since the bottom of the independent directional sensor is a very regular rectangular cross-section plane, the right-angled area formed by the inner sides of the two strip-shaped latches can just clamp and fix one independent directional sensor. The outer sides of the other two strip-shaped latches respectively abut against and limit the corresponding independent directional sensors, thus realizing the installation of three independent directional sensors. When the entire device needs to be installed sideways, the installation positions of the three independent directional sensors inside remain stable and will not shift.

[0037] Meanwhile, after internal positioning and installation, the ring itself has a machined end face on its circumferential wall; and the end face is parallel to one of the strip-shaped latches on the bottom plane inside the base; so the direction can be quickly adjusted from the outside of the ring.

[0038] The installation of the aforementioned strong-motion accelerometer device requires adjustment based on the geographical orientation corresponding to the XYZ geographic coordinate system. However, the plane extension direction of the end plane (the end plane is parallel to one of the strip-shaped latches on the bottom plane inside the base) represents an independent sensor installation direction. Thus, by measuring the plane extension direction of the end plane, the instrument can be quickly positioned and installed.

[0039] The three-axis force-balanced accelerometer consists of three independently oriented sensors (one vertical and two horizontal) integrated into a single unit, with built-in electronic feedback circuitry, control circuitry, and power conversion circuitry. The mounting plate is made of metal steel; the base plate is used for leveling and is equipped with multiple leveling bolts; the base and the ring are fitted together, and a positioning pin is provided between them.

[0040] Preferably, the side-mounted strong shock accelerometer device provided in this embodiment of the present invention further includes a leveling screw; the leveling screw is detachably connected between the base plate and the base.

[0041] Preferably, the upper cover plate is provided with a handle; the handle is an arched handle.

[0042] Preferably, the upper cover plate is also provided with indicator lights, a display screen, a horizontal bubble window, an installation orientation marker, a GNSS socket, and a power network socket.

[0043] For information regarding the installation orientation markings mentioned above, please refer to the following... Figure 6 Z+ corresponds to vertical - up (UD+); Z- corresponds to vertical - down (UD-); X+ corresponds to geographic - east (EW+); X- corresponds to geographic - west (EW-); Y+ corresponds to geographic - north (NS+); Y- corresponds to geographic - south (NS-).

[0044] Preferably, the handle is an arched handle.

[0045] Preferably, the side-mounted strong vibration accelerometer device provided in this embodiment of the present invention further includes an adjustable bottom corner screw and a bottom corner screw back nut; both are installed at the bottom of the mounting plate, and the two together can achieve the adjustment of the height of the mounting plate in the longitudinal direction.

[0046] This utility model discloses a side-mounted strong-motion accelerometer device, which features a highly integrated design (smaller size), light weight, and low power consumption, while also possessing good linearity, wide bandwidth, large dynamic range, and stable performance. This utility model discloses a side-mounted strong-motion accelerometer device suitable for both fixed station observations and mobile field observations, and is particularly suitable for wall mounting to achieve a side-mounted, tilted installation.

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.
