Description

Technical Field

[0001] This utility model belongs to the field of industrial sensing technology, and specifically relates to embedded sensors for equipment vibration monitoring. Background Technology

[0002] Vibration monitoring embedded sensors are vibration detection devices that can sense the vibration measurement information of equipment and transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control, and have been widely used.

[0003] Vibration monitoring embedded sensors are suitable for equipment subjected to strong vibrations, such as wind turbine towers, high-speed motors, and tunnel boring machines. In industrial monitoring scenarios, cable connection failures account for 43% of sensor failures. Especially in environments with vibration frequencies of 5-50Hz, cable breakage due to repeated bending occurs on average within just a few months, forcing equipment to be shut down for maintenance and repair. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an embedded sensor for equipment vibration monitoring.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an embedded sensor for equipment vibration monitoring, comprising:

[0006] A vibration sensing assembly, comprising a vibration sensor body and a threaded mounting component;

[0007] A fastening assembly is located at one end of the vibration sensor body. The fastening assembly includes a hexagonal screw block. A connecting ring is fixedly installed on one side of the hexagonal screw block, penetrating into the interior of the vibration sensor body. A contact ring located inside the vibration sensor body is fixedly sleeved on the surface of the connecting ring. A threaded post that is threadedly connected to the interior of the vibration sensor body is fixedly installed at one end of the connecting ring.

[0008] An open guide assembly, the open guide assembly including a second connecting ring, one end of which is fixedly mounted with an open guide component;

[0009] A guide slip ring is located inside the open guide member.

[0010] Preferably, the vibration sensor body and the threaded mounting component are fixedly connected to each other, and the threaded mounting component is located at the other end of the vibration sensor body.

[0011] Preferably, one end of the vibration sensor body (101) has an embedded cavity, which is used to accommodate and house the contact ring.

[0012] Preferably, the vibration sensor body has a threaded hole inside that communicates with the embedded cavity, and the threaded hole and the threaded post are threadedly connected to each other.

[0013] Preferably, the connecting ring two is fixedly connected to the other side of the hexagonal rotating block, and the open guide is an open design.

[0014] Preferably, an end ring is fixedly installed at one end of the open guide, and an inclined guide surface is formed on the inner side of the end ring.

[0015] Preferably, the guide slip ring and the open guide are fixedly connected to each other, and the guide slip ring is made of ceramic material.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. In use, the threaded mounting component rigidly connects the vibration sensor body to the equipment, ensuring the accuracy of vibration transmission during monitoring. When the equipment is running, the vibration sensor body collects vibration data in real time, while the cable is guided in space through an open guide. The C-shaped opening design of this open guide utilizes the principle of gravity self-alignment to provide flexible support for the drooping cable, reducing the natural bending of the cable from the traditional angle.

[0018] 2. In use, the inclined guide surface on the inner side of the end ring and the open guide form a gradient guiding structure. This transition reduces the bending radius of the cable during cable exit, effectively avoiding stress concentration caused by traditional right-angle exit. Under 50Hz vibration conditions, the fatigue life of the cable conductor is effectively improved. Combined with the polyurethane sheath of the cable's outer layer, the wear rate can be reduced.

[0019] 3. This utility model achieves the disassembly and installation of the connecting ring and the vibration sensor body through the rotational separation of the threaded post and the threaded hole. Furthermore, during subsequent tightening, when the threaded post is screwed into the threaded hole, it is considered to be in place when the contact ring is abutted against the inner side of the embedded cavity and cannot be further advanced. This structure provides installation guidance, is convenient to assemble and disassemble, and offers flexibility. Attached Figure Description

[0031] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0033] refer to Figures 1-6 Embedded sensors for equipment vibration monitoring include:

[0034] Vibration sensing component 1, which includes a vibration sensor body 101 and a threaded mounting component 102;

[0035] Fastening assembly 2 is located at one end of vibration sensor body 101. Fastening assembly 2 includes hexagonal screw block 201. A connecting ring 202 that penetrates into the vibration sensor body 101 is fixedly installed on one side of hexagonal screw block 201. A contact ring 203 located inside the vibration sensor body 101 is fixedly sleeved on the surface of the connecting ring 202. A threaded post 204 that is threadedly connected to the inside of the vibration sensor body 101 is fixedly installed at one end of the connecting ring 202.

[0036] Opening guide assembly 3, the opening guide assembly 3 includes a second connecting ring 301, and an opening guide 302 is fixedly installed at one end of the second connecting ring 301;

[0037] Guide slip ring 4 is located inside the open guide 302.

[0038] In use, the threaded mounting component 102 rigidly connects the vibration sensor body 101 to the equipment, ensuring the accuracy of vibration transmission during monitoring. When the equipment is running, the vibration sensor body 101 collects vibration data in real time, while the cable is guided in space through the open guide 302. The C-shaped opening design of the open guide 302 utilizes the principle of gravity self-alignment to provide flexible support for the drooping cable, reducing the natural bending of the cable from the traditional angle.

[0039] The vibration sensor body 101 and the threaded mounting component 102 are fixedly connected to each other. The threaded mounting component 102 is located at the other end of the vibration sensor body 101. The threaded mounting component 102 cooperates with the vibration sensor body 101 to make a threaded connection and fasten it to the equipment.

[0040] One end of the vibration sensor has an embedded cavity 205, which is used to accommodate the contact ring 203. The embedded cavity 205, together with the vibration sensor body 101, accommodates the contact ring 203. Once the contact ring 203 is inside the embedded cavity 205, the connecting ring 202 can be considered to be installed in place.

[0041] The vibration sensor body 101 has a threaded hole 206 inside that communicates with the embedded cavity 205. The threaded hole 206 and the threaded post 204 are threadedly connected to each other, and the threaded hole 206 cooperates with the vibration sensor body 101 and the threaded post 204 to achieve a tight installation.

[0042] The connecting ring 201 and the other side of the hexagonal rotating block 201 are fixedly connected to each other. The open guide 302 is an open design. The hexagonal rotating block 201 makes it easy for the operator to vibrate the connecting ring 1 202 and the connecting ring 201. The open design of the open guide 302 can support and guide the cable that is drooping under gravity, and prevent it from bending too much.

[0043] An end ring 303 is fixedly installed at one end of the open guide 302. An inclined guide surface 304 is formed on the inner side of the end ring 303. The end ring 303 works with the open guide 302 to extend and guide the cable. The inclined guide surface 304 further works with the end ring 303 to extend and guide the cable. This small-angle transition extension is beneficial for guiding the cable bending and avoiding sudden large-angle bending.

[0044] The guide slip ring 4 and the open guide 302 are fixedly connected to each other. The guide slip ring 4 is made of ceramic material, which ensures smooth friction between the guide slip ring 4 and the cable and reduces the friction between them.

[0045] Brief Description of Usage: In use, the threaded mounting component 102 rigidly connects the vibration sensor body 101 to the equipment, ensuring the accuracy of vibration transmission during monitoring. When the equipment is running, the vibration sensor body 101 collects vibration data in real time, while the cable is guided in space through the open guide 302. The C-shaped opening design of the open guide 302 utilizes the principle of gravity self-alignment to provide flexible support for the drooping cable, reducing the natural bending of the cable from the traditional angle. Furthermore, the inclined guide surface 304 on the inner side of the end ring 303 forms a gradient guide structure with the open guide 302, which reduces the bending radius of the cable during output, effectively avoiding stress concentration caused by traditional right-angle output. Under 50Hz vibration conditions, the fatigue life of the cable conductor is effectively improved, and the wear rate can be reduced in conjunction with the polyurethane sheath of the cable. At the same time, this structure is easy to replace and disassemble. The connection ring 202 and the vibration sensor body 101 can be disassembled and installed by rotating the threaded post 204 and the threaded hole 206. Furthermore, during subsequent tightening, when the threaded post 204 is screwed into the threaded hole 206, and the contact ring 203 is abutted inside the embedded cavity 205 and cannot be further advanced, it is considered to be installed in place.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
