Description

Technical Field

[0001] This utility model relates to the field of vibration sensors, and in particular to an integrated vibration sensor device. Background Technology

[0002] A vibration sensor is a key device used to detect, measure, and monitor the vibration state of an object (such as acceleration, velocity, or displacement). It converts mechanical vibrations into measurable electrical signals through an internal sensing element. These sensors are widely used in predictive maintenance of industrial equipment, structural health monitoring, aerospace testing, automotive NVH analysis, and security and safety applications. Their core value lies in real-time vibration sensing, providing a crucial data foundation for equipment operation safety, fault prediction, and performance optimization.

[0003] Traditional magnetoelectric vibration sensors require external signal conditioning circuits to amplify, filter, and impedance match the output voltage before converting it into a digital signal via a high-precision ADC, resulting in high system complexity and high hardware cost. Utility Model Content

[0004] The present invention aims to provide an integrated vibration sensor device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibration sensor integrated device includes a vibration sensor body, the vibration sensor body being electrically connected to an ammeter and a power supply, the ammeter being electrically connected to a display, the display being electrically connected to the power supply, and the display having a built-in processor that converts electrical signals into vibration data.

[0007] The vibration sensor body includes a housing, with a first spring plate and a second spring plate connected to the inner wall of the housing. The first spring plate and the second spring plate are connected to a core rod, and the core rod is connected to a lead wire. A coil is provided in the inner cavity of the housing, and a permanent magnet is connected to the inner wall of the housing. The housing and the core rod are connected to a damper.

[0008] Preferably, the outer casing is connected to a screw.

[0009] Preferably, the screw is detachably connected to a magnetic block via a thread.

[0010] Preferably, the lead wire is connected to an aviation connector.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] (1) This scheme directly connects the vibration sensor body to a closed loop consisting of an ammeter and a power supply, using the induced current generated by the coil cutting the magnetic field of the permanent magnet as the original signal output. This design eliminates the signal amplification circuit and filtering module required in traditional vibration monitoring systems, significantly simplifying the signal link. The built-in processor in the display can directly convert the current signal into vibration velocity data, realizing the integrated integration of sensing, measurement, and display functions. The damper is rigidly connected to the outer shell and the core rod at both ends, ensuring that mechanical resonance can still be effectively suppressed and measurement stability maintained under the simplified architecture.

[0013] (2) The screw structure connecting the housing provides a rigid mechanical anchoring interface, which can be directly screwed into the standard threaded hole on the surface of the equipment. Compared with the traditional magnetic or adhesive installation method, this design enhances the mechanical coupling strength between the sensor and the measured object, effectively avoids the problem of low-frequency signal distortion caused by loose installation, and expands the applicability of the sensor in high temperature and high vibration environments.

[0014] (3) The screw and magnetic block are connected by a threaded detachable connection, forming a unique dual-mode installation mechanism. When removing the magnetic block, it can be directly fixed to the threaded hole through the screw to meet monitoring requirements; after installing the magnetic block, it can be quickly adsorbed onto the surface of the equipment, especially curved surfaces or narrow spaces. This design greatly improves the deployment efficiency of temporary inspection and solves the pain point of large equipment such as wind turbine gearboxes being difficult to install by drilling.

[0015] (4) The sealed structure of the aviation connector at the end of the lead enhances its tolerance to industrial oil and dust environments, while supporting quick plugging and unplugging of the sensor, significantly improving maintenance convenience. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0020] like Figure 1As shown, the vibration sensor body 1 is electrically connected to an ammeter 2 and a power supply 4. The ammeter 2 is electrically connected to a display 3. The display 3 is electrically connected to the power supply 4. The display 3 has a built-in processor that converts electrical signals into vibration data.

[0021] like Figure 2 As shown, the vibration sensor body 1 includes a housing 5. The inner wall of the housing 5 is connected to a first spring plate 7 and a second spring plate 12. The first spring plate 7 and the second spring plate 12 are connected to a core rod 11. The left side of the core rod 11 is connected to a lead wire 8. A coil 9 is provided on the left side of the inner cavity of the housing 5. The core rod 11 passes through the coil 9. The inner wall of the housing 5 is connected to a permanent magnet 10. The core rod 11 also passes through the center hole of the permanent magnet 10. The housing 5 and the core rod 11 are connected to a damper 13.

[0022] When the outer shell 5 of the vibration sensor body 1 vibrates with the object being measured, the permanent magnet 10 fixed to the inner wall of the outer shell 5 moves synchronously; while the core rod 11, which is elastically suspended by the first spring plate 7 and the second spring plate 12, lags behind due to inertia, causing the coil 9 sleeved on it to move relative to the magnetic field of the permanent magnet 10, cutting the magnetic field lines to generate an induced current. This current is output to the ammeter 2 through the lead wire 8, and its amplitude is proportional to the vibration speed.

[0023] The damper 13 is rigidly fixed at both ends to the outer shell 5 and the core rod 11, respectively. It suppresses resonance by dissipating the relative motion energy between the core rod 11 and the outer shell 5, thereby ensuring the stability of the induced current signal.

[0024] The right side of the outer casing 5 is connected to the screw 14, which is used to directly screw into the threaded hole of the equipment to achieve rigid installation.

[0025] The screw 14 is detachably connected to the magnetic block 15 via a thread. After the magnetic block 15 is installed, it can be attached to the metal surface to meet the needs of rapid deployment.

[0026] The left side of lead 8 is connected to the aviation connector 6. The two poles of the aviation connector 6 are electrically connected to the ammeter 2 and the power supply 4, respectively. Its foolproof design prevents accidental insertion and removal.

[0027] The specific implementation process is as follows:

[0028] The operator first selects the installation mode based on the surface characteristics of the object being measured: if the device has threaded holes, the screw 14 on the right side of the outer casing 5 is screwed in and fixed; if it is a flat or curved metal surface, the magnetic block 15 is screwed onto the end of the screw 14 and adsorbed onto the surface of the device. After installation, the connector 6 of the vibration sensor body 1 is inserted into the corresponding interface of the display 3. At this time, the two poles of the connector 6 are connected to the ammeter 2 and the power supply 4, respectively. When the device vibrates, the outer casing 5 drives the permanent magnet 10 to move synchronously, while the core rod 11, which is elastically suspended, lags behind due to inertia, causing the coil 9 sleeved on it to move axially in the magnetic field of the permanent magnet 10 and cut the magnetic field lines, generating an induced current with an amplitude proportional to the vibration velocity. This current is output to the connector 6 through the lead wire 8, driving the pointer of the ammeter 2 to deflect; at the same time, the current signal is input to the built-in processor of the display 3, and the vibration value is displayed in real time after linear conversion. The damper 13 connects the outer casing 5 and the core rod 11 rigidly, continuously dissipating the relative motion energy between the two, ensuring the stability of the coil 9 cutting the magnetic field. Inspection personnel can directly observe the swing amplitude of the ammeter 2 pointer to qualitatively determine the vibration intensity, or read and record the quantitative data from the display 3. During maintenance, the sensor can be replaced simply by unplugging the aviation connector 6; the entire process requires no external instruments.
