Description

Technical Field

[0001] This utility model relates to the field of equipment fault data acquisition technology, and in particular to an equipment fault data acquisition device. Background Technology

[0002] A voiceprint collector is an electronic component that collects the sound generated by a device during operation and is widely used for fault data acquisition. When a device is operating normally, the frequency of the sound it emits is constant. For example, the noise frequency produced by a motor during normal operation is constant. When a motor malfunctions, the frequency of the noise it produces frequently changes relative to the frequency of sound generated during normal operation. A voiceprint collector collects the noise frequency generated by the motor during operation, providing data for subsequent fault analysis.

[0003] In the existing technology, voiceprint collectors are directly mounted on the motor housing with screws to collect the noise frequency generated during motor operation. Although this mounting method can meet the fixing requirements of the voiceprint collector, it cannot isolate external noise, resulting in large errors in the sound data collected by the voiceprint collector.

[0004] Therefore, existing equipment fault data acquisition devices suffer from the technical problem of large data errors. Utility Model Content

[0005] This utility model provides a device for acquiring equipment fault data, which solves the technical problem of large data errors in existing equipment fault data acquisition devices.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A device for collecting equipment fault data includes a soundproof cylinder installed on the device to be monitored, and the soundproof cylinder is provided with a soundproof cover;

[0008] An installation cavity is formed between the sound insulation cylinder and the sound insulation cover;

[0009] The soundproof cover is provided with a soundproof shield, which is located inside the mounting cavity. Furthermore, a voiceprint collector is provided inside the soundproof shield, and the soundproof cover positions the voiceprint collector to the device to be monitored through the soundproof shield.

[0010] The soundproof cylinder includes an inner cylinder and an outer cylinder sleeved outside the inner cylinder. A first soundproof cavity is formed between the inner cylinder and the outer cylinder. The soundproof cover is fixed to the soundproof cylinder by screws. Both the inner cylinder and the outer cylinder are provided with screw holes that cooperate with the screws. The screws include an inner screw that cooperates with the screw hole of the inner cylinder and an outer screw that cooperates with the screw hole of the outer cylinder. The inner screw and the outer screw have opposite directions of rotation.

[0011] Preferably, the inner screws are evenly arranged along the circumference of the inner cylinder, and the outer screws are evenly arranged along the circumference of the outer cylinder.

[0012] Preferably, an elastic sound-insulating pad is provided between the sound-insulating cover and the inner cylinder and the outer cylinder, and the elastic sound-insulating pad is provided with a through hole communicating with the screw hole.

[0013] Preferably, the elastic sound insulation pad is a rubber pad, and the elastic sound insulation pad is adhered to the sound insulation cover.

[0014] Preferably, the soundproof cover is further provided with a first reinforcing ring, which extends into the first soundproof cavity, and the first reinforcing ring and the soundproof cover are an integral structure.

[0015] Preferably, the soundproof cover is also provided with a positioning ring for positioning the soundproof cover. The positioning ring and the soundproof cover are an integral structure, and the soundproof cover is snapped onto the soundproof cover by the positioning ring.

[0016] Preferably, a second sound insulation cavity is formed between the inner cylinder and the sound insulation cover, and the positioning ring extends into the second sound insulation cavity. The length of the positioning ring protruding from the sound insulation cover is less than the length of the first reinforcing ring protruding from the sound insulation cover.

[0017] Preferably, the soundproof cover is provided with an inner soundproof cavity, and an outer soundproof cavity is provided outside the inner soundproof cavity. The inner soundproof cavity and the outer soundproof cavity are not connected, and the voiceprint collector is located in the inner soundproof cavity.

[0018] Preferably, both the soundproof cover and the soundproof enclosure are provided with wiring holes, through which the cable of the soundprint collector extends out of the mounting cavity.

[0019] Preferably, the voiceprint collector includes a collection head that contacts the device to be monitored, and the soundproof cover is also provided with a positioning shoulder, with one end of the voiceprint collector away from the collection head contacting the positioning shoulder.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By setting up soundproof cylinders and soundproof covers, and then installing soundproof shields on the soundproof covers, the voiceprint collector is installed inside the soundproof shields. The soundproof cylinders, soundproof covers, and soundproof shields are all used to isolate external noise. The voiceprint collector only collects the noise generated during the operation of the device under monitoring, which greatly reduces the interference of external noise on the voiceprint collector and improves the accuracy and precision of the data collected by the voiceprint collector.

[0022] By configuring the soundproof cylinder as an inner and outer cylinder, with the outer cylinder fitted over the inner cylinder, the soundproof cylinder adopts a double-layer structure, further optimizing its sound insulation effect and effectively reducing the interference of external noise on the voiceprint collector. Similarly, by setting up a soundproof cover, the interference of external noise on the voiceprint collector is further reduced, improving the collection accuracy of the voiceprint collector.

[0023] By setting internal and external screws, and making the internal and external screws rotate in opposite directions, the stability of the soundproof cover can still be effectively guaranteed when one of the internal or external screws becomes loose, making the soundproof cover less likely to detach and improving the stability of the connection between the soundproof cover and the soundproof cylinder.

[0036] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0038] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Reference Figures 1 to 6 As shown, a device fault data acquisition device includes a soundproof cylinder 1 installed on the device to be monitored 100, and the soundproof cylinder 1 is provided with a soundproof cover 2;

[0040] An installation cavity is formed between the soundproofing cylinder 1 and the soundproofing cover 2;

[0041] The soundproof cover 2 is provided with a soundproof shield 3, which is located inside the installation cavity. Furthermore, a voiceprint collector 31 is provided inside the soundproof shield 3, and the soundproof cover 2 positions the voiceprint collector 31 to the device 100 to be monitored through the soundproof shield 3.

[0042] The soundproof cylinder 1 includes an inner cylinder 11 and an outer cylinder 12 sleeved outside the inner cylinder 11. A first soundproof cavity 13 is formed between the inner cylinder 11 and the outer cylinder 12. The soundproof cover 2 is fixed to the soundproof cylinder 1 by screws. Both the inner cylinder 11 and the outer cylinder 12 are provided with screw holes that cooperate with the screws. The screws include an inner screw 21 that cooperates with the screw hole of the inner cylinder 11 and an outer screw 22 that cooperates with the screw hole of the outer cylinder 12. The inner screw 21 and the outer screw 22 have opposite directions of rotation.

[0043] In some embodiments, the voiceprint collector 31 is a common electronic device in the prior art, and its working principle and specific structure are not limited, referring to the prior art. The voiceprint collector 31 collects the noise generated when the device is working, such as a motor. The voiceprint collector 31 collects the noise generated during the operation of the motor, and when the motor fails, the cause of the motor failure can be analyzed based on the noise data.

[0044] In some embodiments, although screw connections have high stability, screw connections often have the technical problem of being prone to loosening. For example, when the equipment is working in a vibrating environment, the screw may loosen. Usually, the vibration of the vibrating environment is frequent or has a consistent direction, so such vibration may cause the screw to loosen.

[0045] By making the inner screw 21 and the outer screw 22 rotate in opposite directions, the inner screw 21 and the outer screw 22 can withstand vibrations in different directions, thus making it less likely for the inner screw 21 and the outer screw 22 to loosen at the same time, thereby improving the stability of the connection between the soundproof cover 2 and the soundproof cylinder 1.

[0046] Reference Figures 1 to 6 As shown, in some embodiments, a connection structure can also be provided between the inner screw 21 and the outer screw 22. For example, the inner screw 21 and the outer screw 22 can be connected by a metal wire, that is, the inner screw 21 and the outer screw 22 are bound together by a metal wire to form a whole, so that the inner screw 21 and the outer screw 22 will not loosen, further improving the stability of the connection piece between the soundproof cover 2 and the soundproof cylinder 1.

[0047] In some embodiments, the inner screws 21 are uniformly arranged along the circumferential direction of the inner cylinder 11, and the outer screws 22 are uniformly arranged along the circumferential direction of the outer cylinder 12.

[0048] The more inner screws 21 and outer screws 22 are installed, the stronger the connection between the soundproof cover 2 and the soundproof cylinder 1 will be.

[0049] In some embodiments, the soundproof cylinder 1 may be welded to the housing of the device 100 to be monitored. Alternatively, the soundproof cylinder 1 may be an integral part of the housing of the device 100 to be monitored.

[0050] In some embodiments, an elastic sound insulation pad 23 is provided between the sound insulation cover 2 and the inner cylinder 11 and the outer cylinder 12, and the elastic sound insulation pad 23 is provided with a through hole communicating with the screw hole.

[0051] The elastic sound insulation pad 23 is a rubber pad, and the elastic sound insulation pad 23 is bonded to the sound insulation cover 2.

[0052] In some embodiments, the soundproof cover 2 is further provided with a first reinforcing ring 24, which extends into the first soundproof cavity 13, and the first reinforcing ring 24 and the soundproof cover 2 are an integral structure.

[0053] The soundproof cover 2 is also provided with a positioning ring 25 for positioning the soundproof cover 3. The positioning ring 25 and the soundproof cover 2 are an integral structure, and the soundproof cover 3 is snapped onto the soundproof cover 2 by the positioning ring 25.

[0054] The first reinforcing ring 24 and the positioning ring 25 make it easy to assemble the soundproof cover 2 and the soundproof cylinder 1. At the same time, the positioning ring 25 makes it easy to install the soundproof cover 3 onto the soundproof cover 2.

[0055] In some embodiments, the soundproof cover 3 may be made of rubber material and is snapped onto the positioning ring 25 by means of elastic deformation.

[0056] In some embodiments, a second sound insulation cavity 26 is formed between the inner cylinder 11 and the sound insulation cover 3, and the positioning ring 25 extends into the second sound insulation cavity 26. The length of the positioning ring 25 protruding from the sound insulation cover 2 is less than the length of the first reinforcing ring protruding from the sound insulation cover 2.

[0057] The second soundproof cavity 26 is used to optimize the soundproof performance of the soundproof cover 3, so that external noise is less likely to interfere with the voiceprint collector 31.

[0058] Reference Figures 1 to 6 As shown, in some embodiments, the soundproof cover 3 is provided with an inner soundproof cavity 32, and an outer soundproof cavity 33 is provided outside the inner soundproof cavity 32. The inner soundproof cavity 32 and the outer soundproof cavity 33 are not connected. The voiceprint collector 31 is disposed in the inner soundproof cavity 32. The outer soundproof cavity 33 further optimizes the soundproof performance of the soundproof cover 3.

[0059] In some embodiments, both the soundproof cover 3 and the soundproof cover 2 are provided with wiring holes, through which the cable of the voiceprint collector 31 extends out of the mounting cavity.

[0060] In some embodiments, the voiceprint collector 31 includes a collection head 311, which contacts the device to be monitored 100. The soundproof cover 3 is also provided with a positioning shoulder, and one end of the voiceprint collector 31 away from the collection head 311 contacts the positioning shoulder.

[0061] The voiceprint collector 31 is connected to the device under monitoring 100 in a contact manner. The fasteners between the voiceprint collector and the device under monitoring 100 prevent noise interference caused by loose fasteners, thereby further improving the data acquisition accuracy of the voiceprint collector 31.

[0062] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0063] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0064] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings.
