Description

Technical Field

[0001] This utility model relates to the field of wiring technology for piezoelectric integrated vibration sensors, and in particular to a wiring structure for piezoelectric integrated vibration sensors that is easy to wire. Background Technology

[0002] A piezoelectric integrated vibration sensor is an electromechanical conversion device based on the piezoelectric effect. It achieves efficient conversion of vibration quantity into electrical signal through built-in signal conditioning circuit. In industrial production, in order to reduce the downtime and maintenance costs of motors on conveyors, piezoelectric integrated vibration sensors are usually installed on the motors. They can monitor the vibration of the equipment in real time, detect potential equipment failures in a timely manner, and thus achieve preventive maintenance of the equipment.

[0003] Most existing piezoelectric integrated vibration sensors use plug-in interfaces to connect to the cable socket on the motor. However, the vibration force generated by the motor during operation can be easily transmitted to the cable plug and cable socket, which can easily cause the cable plug and cable socket to loosen, thus affecting the monitoring effect. Utility Model Content

[0004] Therefore, it is necessary to provide a wiring structure for a piezoelectric integrated vibration sensor that facilitates wiring, addressing the problem that the vibration force generated by the motor during operation can be easily transmitted to the cable plug and cable socket, which can lead to the loosening of the cable plug and cable socket.

[0005] Includes: a plug and a socket; an anti-loosening mechanism, the anti-loosening mechanism including a threaded sleeve slidably connected to the surface of the plug, the surface of the threaded sleeve being threadedly connected to the inner wall of the socket, a mounting ring being fixedly connected to the surface of the socket, the surface of the threaded sleeve being slidably connected to the inner wall of the mounting ring, a mounting cylinder being fixedly connected to the surface of the mounting ring, a positioning rod being slidably connected to the inner wall of the mounting cylinder, and the surface of the positioning rod being slidably connected to the inner walls of the mounting ring and the threaded sleeve in sequence.

[0006] In one embodiment, a limiting rod is slidably connected to the upper end of the inner wall of the positioning rod, and the end of the limiting rod contacts the inner top wall of the mounting cylinder.

[0007] In one embodiment, a spring is fixedly connected to the opposite end of the positioning rod and the mounting cylinder.

[0008] In one embodiment, an anti-slip pad is slidably connected to the inner wall of the mounting cylinder, and the bottom end of the anti-slip pad contacts the top end of the positioning rod.

[0009] In one embodiment, both the threaded sleeve and the mounting ring have annularly distributed grooves on their surfaces.

[0010] In one embodiment, a limiting ring is fixedly connected to the surface of the plug, and the inner wall of the threaded sleeve is slidably connected to the surface of the limiting ring. The limiting ring limits the threaded sleeve, preventing it from detaching from the plug surface.

[0011] In one embodiment, a limiting rope is fixedly connected to the surface of the anti-slip mat, and the other end of the limiting rope is fixedly connected to the surface of the mounting cylinder.

[0012] In one embodiment, both the threaded sleeve and the mounting ring are nylon components.

[0013] Beneficial effects

[0014] 1. By using a threaded sleeve, the plug is stably inserted into the socket, thereby reducing the possibility of loosening between the plug and the socket. Through the cooperation of the threaded sleeve, mounting ring, mounting cylinder and positioning rod, the threaded sleeve is stably threaded in the socket, thereby improving the connection between the plug and the socket. Compared with the existing piezoelectric integrated vibration sensor where the plug and the socket on the motor are prone to loosening, this method avoids the loosening of the plug and the socket on the motor, thus ensuring the monitoring effect.

[0015] 2. By using the spring clip, limit rod and anti-slip pad in cooperation, the positioning rod is stably locked in the threaded sleeve, thus ensuring that the threaded sleeve is stably installed in the socket, thereby avoiding loosening at the connection between the plug and the socket.

[0028] The following is combined Figures 1-4 This invention describes the wiring structure of a piezoelectric integrated vibration sensor that facilitates wiring.

[0029] In one embodiment, a wiring structure for a piezoelectric integrated vibration sensor that facilitates wiring includes: a plug 100 and a socket 200; an anti-loosening mechanism 300, the anti-loosening mechanism 300 including a threaded sleeve 302 slidably connected to the surface of the plug 100, the surface of the threaded sleeve 302 being threadedly connected to the inner wall of the socket 200, a mounting ring 301 being fixedly connected to the surface of the socket 200, the surface of the threaded sleeve 302 being slidably connected to the inner wall of the mounting ring 301, a mounting cylinder 303 being fixedly connected to the surface of the mounting ring 301, a positioning rod 304 being slidably connected to the inner wall of the mounting cylinder 303, the surface of the positioning rod 304 being slidably connected to the inner walls of the mounting ring 301 and the threaded sleeve 302 in sequence, and both the threaded sleeve 302 and the mounting ring 301 being nylon components.

[0030] The threaded sleeve 302 and mounting ring 301 of the nylon component are made of nylon PA66, which has high strength, wear resistance and high temperature resistance, and also has good toughness. It can buffer external impact to a certain extent and protect the plug 100 and socket 200 from damage.

[0031] It should be noted that: one end of the wire of plug 100 is connected to one side of the piezoelectric integrated vibration sensor, and one end of the wire of socket 200 is connected to the surface of the motor on the conveyor. The piezoelectric integrated vibration sensor is installed at a suitable position on the conveyor frame or motor surface using bolts. The threaded sleeve 302 is then threaded into socket 200, allowing plug 100 to be inserted into socket 200, thus completing the wiring between the piezoelectric integrated vibration sensor and the motor. When the motor vibrates during operation, the vibration is transmitted to the piezoelectric integrated vibration sensor. The piezoelectric material inside the sensor generates an electric charge when subjected to mechanical stress, and the amount of charge is proportional to the acceleration of the vibration. The weak electric charge signal generated by the piezoelectric material is converted into a voltage signal through a built-in charge amplifier or voltage amplifier.

[0032] The collected vibration signals may contain various noise and interference signals. Unwanted frequency components are removed using methods such as low-pass filtering, high-pass filtering, or band-pass filtering, retaining the characteristic frequency signals related to motor faults.

[0033] Time-domain analysis is performed on the filtered signal to calculate parameters such as peak value, mean value, and root mean square value of the vibration signal. These parameters reflect the intensity and stability of the motor vibration. For example, a sudden increase in the root mean square value of the vibration signal may indicate abnormal vibration in the motor.

[0034] The time-domain signal is converted into a frequency-domain signal using methods such as Fourier transform, allowing for the analysis of the frequency components of the vibration signal. Motors generate vibration signals with different characteristic frequencies under normal operation and fault conditions. For example, a motor bearing fault will produce specific fault characteristic frequencies; frequency domain analysis can identify these frequency components and determine whether a bearing fault exists in the motor.

[0035] Feature parameters related to motor faults, such as the amplitude and phase of specific frequency components, are extracted from the processed vibration signal. These feature parameters can serve as the basis for fault diagnosis. The extracted feature parameters are compared with pre-set normal thresholds or fault models. If the feature parameters exceed the normal range, it is determined that the motor may have a fault.

[0036] In this embodiment, the threaded sleeve 302 is threadedly installed in the socket 200 and slides into the mounting ring 301. The positioning rod 304 moves down and slides into the threaded sleeve 302, thereby positioning the threaded sleeve 302 so that the plug 100 is stably inserted into the socket 200.

[0037] like Figure 4 As shown, a limiting rod 305 is slidably connected to the upper end of the inner wall of the positioning rod 304. The end of the limiting rod 305 contacts the inner top wall of the mounting cylinder 303. A spring piece 307 is fixedly connected to the opposite end of the positioning rod 304 and the mounting cylinder 303. An anti-slip pad 306 is slidably connected to the inner wall of the mounting cylinder 303. The bottom end of the anti-slip pad 306 contacts the top end of the positioning rod 304. A limiting rope 308 is fixedly connected to the surface of the anti-slip pad 306. The other end of the limiting rope 308 is fixedly connected to the surface of the mounting cylinder 303.

[0038] The mounting cylinder 303, positioning rod 304, limiting rod 305, anti-slip pad 306, and limiting rope 308 are all silicone rubber components, which have good elasticity, friction and high temperature resistance.

[0039] In this embodiment, the elastic force of the spring 307 pushes the positioning rod 304 and the limiting rod 305 to move down automatically, so that the positioning rod 304 automatically slides into the threaded sleeve 302. The limiting rod 305 is rotated so that the end of the limiting rod 305 abuts against the inner top wall of the mounting cylinder 303, and the anti-slip pad 306 slides into the mounting cylinder 303 and abuts against the top of the positioning rod 304.

[0040] like Figure 3As shown, both the threaded sleeve 302 and the mounting ring 301 have annularly distributed grooves 310 on their surfaces. The plug 100 is fixedly connected to a limiting ring 309, and the inner wall of the threaded sleeve 302 is slidably connected to the surface of the limiting ring 309.

[0041] Working principle: The threaded sleeve 302 is threaded into the socket 200 and slides into the mounting ring 301. The elastic force of the spring piece 307 pushes the positioning rod 304 and the limiting rod 305 to move down automatically, so that the positioning rod 304 automatically slides into the threaded sleeve 302. The limiting rod 305 is rotated so that the end of the limiting rod 305 abuts against the inner top wall of the mounting cylinder 303, and the anti-slip pad 306 slides into the mounting cylinder 303 and abuts against the top of the positioning rod 304, thereby positioning the threaded sleeve 302 and making the plug 100 stably inserted into the socket 200.

[0042] It should be noted that the plug 100, socket 200 and spring contact 307 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the plug 100 and socket 200 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
