However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the present application.

[0028] Please refer to Figure 1 and Figure 2 The vibration sensor isolation device in the first embodiment of the present application comprises: a first connecting seat 1, a second connecting seat 2 and an insulating isolation sleeve 3. One end of the first connecting seat 1 is detachably fixedly installed on the detected point, the other end of the first connecting seat 1 is detachably fixedly installed on the insulating isolation sleeve 3, one end of the second connecting seat 2 is detachably fixedly installed on the vibration sensor, the other end of the second connecting seat 2 is detachably fixedly installed on the insulating isolation sleeve 3, and the insulating isolation sleeve 3 is detachably fixedly installed between the first connecting seat 1 and the second connecting seat 2. The insulating isolation sleeve 3 is provided with a containing cavity 31 for storing the detection head of the vibration sensor, so that the insulating isolation sleeve 3 wraps the detection head of the vibration sensor.

[0029] The insulating isolation sleeve 3 is made of insulating and non-conductive material, which can insulate the electric signal to a certain extent. The insulating isolation sleeve 3 can be made of thermoplastic material, which is convenient for processing and can be suitable for various shapes. Its damping effect on mechanical vibration is limited, and the material with rigidity meeting the frequency range of 10HZ to 1000HZ is selected.

[0030] The insulating isolation sleeve 3 is detachably fixedly installed between the first connecting seat 1 and the second connecting seat 2, and the insulating isolation sleeve 3 is internally provided with a containing cavity 31 for storing the vibration sensor detection head, so that the insulating isolation sleeve 3 wraps the vibration sensor detection head. The electrical signal generated by the device is isolated by the insulating isolation sleeve 3, so as to avoid affecting the internal vibration sensor detection head. Since the insulating isolation sleeve 3 wraps the vibration sensor detection head, when the device vibrates, the vibration frequency is transmitted to the first connecting seat 1 which is detachably fixedly connected to the insulating isolation sleeve 3, so as to drive the first connecting seat 1 to generate the same vibration frequency, and then the vibrating first connecting seat 1 drives the other end of the detachably fixedly connected insulating isolation sleeve 3 to vibrate, so that the vibration frequency of the insulating isolation sleeve 3 is transmitted to the vibration sensor detection head in the internal containing cavity 31. The vibration sensor detection head only receives the vibration frequency generated at the detected point connected to the first connecting seat 1, thereby reducing the interference of the surrounding electrical signal, improving the stability of the monitoring value of the vibration sensor, making the monitoring data of the vibration sensor more accurate, improving the monitoring efficiency of the rotating equipment, timely adjusting the equipment, reducing the damage of the equipment, and prolonging the service life.

[0031] The second connecting seat 2 is connected to the vibration sensor, which can further improve the stability of the vibration sensor detection head in the containing cavity 31, prevent the vibration sensor detection head from being detached during monitoring, and maintain stable monitoring accuracy and real-time during long-term monitoring of the equipment, thereby further improving the stability of the monitoring value of the vibration sensor, making the monitoring data of the vibration sensor more accurate, improving the monitoring efficiency of the rotating equipment, timely adjusting the equipment, reducing the damage of the equipment, and prolonging the service life.

[0032] Please refer to Figure 1 and Figure 2 In some embodiments, the vibration sensor isolation device further comprises a plurality of locking members 4 for detachably fixing the first connecting seat 1 and the second connecting seat 2 at both ends of the insulating isolation sleeve 3, and a plurality of first through holes 5 corresponding to the locking members 4 are formed in the first connecting seat 1 and the second connecting seat 2.

[0033] This application utilizes the cooperation between the locking element 4 and the first through hole 5 to detachably connect the first connecting seat 1 and the second connecting seat 2 to both ends of the insulating isolation sleeve 3. After the insulating isolation sleeve 3 wears out, the locking element 4 can be opened to separate the first connecting seat 1 and the second connecting seat 2 from the insulating isolation sleeve 3, allowing for replacement of the worn insulating isolation sleeve 3. This facilitates maintenance and saves on maintenance costs. Furthermore, the connection between the locking element 4 and the first connecting seat 1 or the second connecting seat 2 via the first through hole 5 makes the vibration sensor isolation device more aesthetically pleasing, reduces accidental contact or disassembly by unauthorized personnel, and improves safety and monitoring stability.

[0034] The locking element 4 can be a snap-fit ​​structure, with matching positioning grooves on the first connecting seat 1 and the second connecting seat 2. The locking element 4 is an expansion pin with a limiting protrusion at its top. When the end of the locking element 4 with the limiting protrusion passes through the first through hole 5 and reaches the positioning groove on the first connecting seat 1 and the second connecting seat 2, the expansion pin expands to both sides, and the limiting protrusion enters the positioning groove, thus fixing the first connecting seat 1 and the second connecting seat 2 in the insulating sleeve 3. This facilitates installation and improves installation efficiency.

[0035] Alternatively, the locking element 4 can be a bolt, which uses a threaded pair to fix the first connecting seat 1 and the second connecting seat 2 to the insulating isolation sleeve 3, making disassembly and installation easier and improving maintenance efficiency.

[0036] Please see Figure 1 and Figure 2 In some embodiments, the insulating sleeve 3 has multiple countersunk holes 6 in opposite directions, and the locking member 4 includes: a first locking member 41 and a second locking member 42. The first locking member 41 passes through the countersunk hole 6 in the forward direction and cooperates with the first through hole 5 to be fixedly connected to the first connecting seat 1; the second locking member 42 passes through the remaining countersunk holes 6 in the reverse direction and cooperates with the first through hole 5 to be fixedly connected to the second connecting seat 2.

[0037] The first locking piece 41 and the second locking piece 42 are matched with the respective counterbores 6, so that the first locking piece 41 is used to detachably and fixedly install the first connecting seat 1 and the insulating isolation sleeve 3 together in the forward direction, and then the second locking piece 42 is used to detachably and fixedly install the second connecting seat 2 and the insulating isolation sleeve 3 together in the reverse direction, so that the connecting directions of the first locking piece 41 and the second locking piece 42 are opposite. Since the whole vibration sensor isolation device is installed between the rotating equipment and the vibration sensor, the vibration generated by the rotating equipment is transmitted to the vibration sensor isolation device, so that the first connecting seat 1 and the second connecting seat 2 vibrate on the insulating isolation sleeve 3. The detachable and fixed connection mode of the first locking piece 41 and the second locking piece 42 in opposite directions can effectively prevent the first connecting seat 1 and the second connecting seat 2 from separating to both sides on the insulating isolation sleeve 3, so that the first connecting seat 1 and the second connecting seat 2 can be more stably connected on the insulating isolation sleeve 3. The influence of the vibration frequency of the first connecting seat 1, the insulating isolation sleeve 3 and the second connecting seat 2 on the detection head of the vibration sensor is reduced, so that the vibration sensor detection head in the containing cavity 31 can more stably monitor the vibration frequency transmitted by the rotating equipment, and the accuracy of the vibration sensor detection head in monitoring the vibration of the rotating equipment is improved.

[0038] Please refer to Figure 1 and Figure 2 In some embodiments, the first locking piece 41 comprises a first screw 411 and a first threaded hole 412 formed in the first through hole 5 of the first connecting seat 1. The front part of the first screw 411 is connected in the first threaded hole 412 through a threaded pair in the forward direction through the counterbores 6. The second connecting seat 2 is provided with a second through hole 21 corresponding to the position of the first threaded hole 412.

[0039] The first screw 411, the first threaded hole 412 and the corresponding counterbores 6 are matched with each other to detachably connect the first connecting seat 1 to the insulating isolation sleeve 3, which is convenient for disassembly and installation and can save the cost of production.

[0040] Please refer to Figure 1 and Figure 2 In some embodiments, the second locking piece 42 comprises a second screw 421 and a second threaded hole 422 formed in the first through hole 5 of the second connecting seat 2. The front part of the second screw 421 is connected in the second threaded hole 422 through a threaded pair in the reverse direction through the counterbores 6.

[0041] The second screw 421 is reversely threaded through the counterbore 6 and connected in the second threaded hole 422 through a threaded pair, and the second connecting seat 2 is detachably connected on the insulating isolation sleeve 3 through cooperation of the second screw 421, the second threaded hole 422 and the corresponding counterbore 6, which facilitates dismounting and installation and saves manufacturing cost.

[0042] Please refer to Figure 1 and Figure 2 In some embodiments, the second connecting seat 2 is provided with a second through hole 21 corresponding to the position of the first threaded hole 412.

[0043] When the first screw 411 and the second screw 421 are installed in opposite directions, the front part of the second screw 421 is first threaded through the counterbore 6 and connected in the second threaded hole 422 of the second connecting seat 2, so that the second connecting seat 2 is stably connected on one end of the insulating isolation sleeve 3, then the first screw 411 is threaded through the second through hole 21, the corresponding counterbore 6 and connected in the first threaded hole 412, so that the first connecting seat 1 is stably connected on the other end of the insulating isolation sleeve 3. When dismounting, the tool is first inserted into the second through hole 21 to dismount the first screw 411, so that the first connecting seat 1 is separated from the insulating isolation sleeve 3, and the second screw 421 is exposed on the other end of the insulating isolation sleeve 3, then the tool is used to dismount the second screw 421, so that the second connecting seat 2 is separated from the insulating isolation sleeve 3. The second screw 421 is blocked on the other end of the insulating isolation sleeve 3 by the first connecting seat 1, which can further improve the stability of the connection between the second connecting seat 2 and the insulating isolation sleeve 3, make the detection head of the vibration sensor in the accommodating cavity 31 more stable, and further improve the accuracy and stability of the vibration monitoring of the rotating equipment.

[0044] Please refer to Figures 1 to 4 In some embodiments, the end of the first connecting seat 1 away from the insulating isolation sleeve 3 is provided with a threaded column 7 connected with a detected point through a threaded pair; and the end of the first connecting seat 1 away from the insulating isolation sleeve 3 is provided with a third threaded hole 8 connected with a vibration sensor.

[0045] The end of the first connecting seat 1 away from the insulating isolation sleeve 3 is provided with a threaded column 7 connected with a detected point through a threaded pair. The first connecting seat 1 is connected on the detected point through the threaded column 7, which facilitates installation and improves the efficiency of installation and the stability of monitoring.

[0046] The application is provided with a third threaded hole 8 connected with the vibration sensor at the end of the first connecting seat 1 away from the insulating isolation sleeve 3. The cooperation between the third threaded hole 8 and the vibration sensor facilitates the installation of the vibration sensor isolation device on the vibration sensor, improves the installation efficiency and monitoring stability, and relieves the installation pressure of the vibration sensor detection head, reduces the abrasion of the vibration sensor detection head, and further prolongs the service life.

[0047] Please refer to Figure 1 and Figure 2 In some embodiments, the shape of the accommodation cavity 31 is consistent with the shape of the vibration sensor detection head.

[0048] The application is provided with the accommodation cavity 31, which is consistent with the shape of the vibration sensor detection head. After the vibration sensor detection head is inserted into the accommodation cavity 31, the insulating isolation sleeve 3 can be more closely wrapped on the vibration sensor detection head, reducing the gap between the vibration sensor detection head and the inner wall of the accommodation cavity 31, avoiding the abrasion of the vibration sensor detection head during monitoring, prolonging the service life, and making the vibration sensor detection head more sensitive to follow the vibration of the insulating isolation sleeve 3, improving the accuracy of the monitoring value, and further avoiding the intrusion of the surrounding electrical signals.

[0049] Please refer to Figures 1 to 3 In some embodiments, at least one of the first connecting seat 1, the second connecting seat 2 and the insulating isolation sleeve 3 is provided in a regular hexagonal shape.

[0050] The application is provided with the first connecting seat 1, the second connecting seat 2 and the insulating isolation sleeve 3, at least one of which is provided in a regular hexagonal shape. The first connecting seat 1, the second connecting seat 2 and the insulating isolation sleeve 3 in a regular hexagonal shape facilitate the personnel to use a wrench to clamp the periphery of the vibration sensor isolation device, and to rotate the vibration sensor isolation device to drive the threaded column 7 to be installed on the detected point more conveniently and labor-saving, improving the installation efficiency.

[0051] Please refer to Figures 1 to 4 In some embodiments, the vibration sensor isolation device further comprises a counterweight 9 detachably installed on the first connecting seat 1 and / or the second connecting seat 2.

[0052] The weight block 9 can increase the weight of the vibration sensor isolation device, and the vibration amplitude transmitted to the vibration sensor isolation device is increased when the rotating equipment generates vibration, since the detected point and the mounting point are both the end of the vibration sensor isolation device, wherein the weight block 9 mounted on the second connecting seat 2 and the first connecting seat 1 can adjust the gravity center of the vibration sensor isolation device, so that the gravity center of the vibration sensor isolation device is deviated to the detected point, and the vibration amplitude of the vibration sensor isolation device is reduced by mounting the weight block 9 on the first connecting seat 1, so that the value monitored by the vibration sensor detection head is closer to the vibration frequency of the rotating equipment, and the monitored value is more accurate.

[0053] Please refer to Figure 1 and Figure 2 In some embodiments, the first connecting seat 1 and / or the second connecting seat 2 is internally provided with a limiting groove 10 for accommodating the weight block 9.

[0054] The limiting groove 10 is internally provided with a limiting groove 10 for accommodating the weight block 9, and the weight block 9 is stably mounted in the first connecting seat 1 and / or the second connecting seat 2, which can reduce the volume of the vibration sensor isolation device, avoid the weight block 9 being touched by irrelevant personnel, further reduce the vibration amplitude of the vibration sensor isolation device, make the value monitored by the vibration sensor detection head closer to the vibration frequency of the rotating equipment, and make the monitored value more accurate. The wedge-shaped limiting groove 10 can improve the stability of the weight block 9 in the first connecting seat 1 and / or the second connecting seat 2, and further reduce the vibration amplitude of the vibration sensor isolation device.
