[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] See Figure 1As shown, this application provides a fault prediction device for a power rotating device 10, including a power rotating device 10, a vibration sensor 20, a current transformer 30, and a temperature sensor 40. The power rotating device 10 includes a power source 11, a housing 12, and a support member 13. The power source 11 includes a main body 111 and a rotating output part 112 connected to the main body 111. The housing 12 covers one side of the main body 111, and a mounting cavity 14 is defined between the housing 12 and the main body 111. The rotating output part 112 passes through the housing 12. The support member 13 is located at the mounting cavity 111. The cavity 14 is fitted onto the rotating output section 112; a vibration sensor 20 is installed inside the housing 12 and in contact with the support member 13. The vibration sensor 20 is used to monitor the vibration frequency and intensity of the support member 13 and the rotating output section 112; a current transformer 30 is used to monitor the current of the power source 11; a temperature sensor 40 is installed inside the housing 12 and is used to monitor the temperature inside the mounting cavity 14; the monitoring mechanism 50 is electrically connected to the vibration sensor 20, the current transformer 30 and the temperature sensor 40.

[0052] Understandably, the power source 11 may include one of the following: a motor, a gearbox, a turbine, or a fan. The rotating output section 112 of the power source 11 may be a rotating shaft, and the support member 13 may include a bearing. The vibration sensor 20 contacts the support member 13, thereby monitoring the vibration frequency and intensity of the support member 13 and the rotating output section 112. Based on the vibration frequency and intensity, faults such as bearing wear and shaft misalignment can be located. When the power source 11 is connected to an external power supply, the current transformer 30 monitors the current connected to the power source 11, which can locate faults such as short circuits in the wiring harness and power imbalance. Temperature sensor 40 is used to monitor the temperature of mounting cavity 14, thereby monitoring the temperature at the connection between support 13 and rotary output part 112. Based on the monitored temperature, problems such as lubrication failure and abnormal heat dissipation can be located. The monitoring mechanism 50 can predict the faults of the power rotating equipment 10 based on the information monitored by vibration sensor 20, current transformer 30 and temperature sensor 40, thereby facilitating users to find and deal with fault points in a timely manner, increasing monitoring efforts, reducing the size of faults, and avoiding serious damage to the power rotating equipment 10 and the inconvenience caused by long-term downtime for maintenance.

[0053] In summary, the fault prediction device for the power rotation equipment 10 provided in this application embodiment has a housing 12 covering one side of the main body 111 of the power source 11, and a mounting cavity 14 is defined between the housing 12 and the main body 111. The rotation output part 112 of the power source 11 passes through the housing 12. The support member 13 is located in the mounting cavity 14 and is sleeved on the rotation output part 112. The vibration sensor 20 passes through the housing 12 and is in contact with the support member 13. The current transformer 30 is used to monitor the current of the power source 11. The temperature sensor 40 passes through the housing 12 and is used to monitor the temperature inside the mounting cavity 14. The monitoring mechanism 50 is electrically connected to the vibration sensor 20, the current transformer 30, and the temperature sensor 40. By using vibration sensor 20, current transformer 30 and temperature sensor 40, the vibration of the support member 13 and the rotating output part 112 of the power rotating equipment 10, the temperature at the connection between the support member 13 and the rotating output part 112, and the current of the power source 11 can be monitored. The monitoring mechanism 50 can predict the faults of the power rotating equipment 10 by monitoring the changes in vibration frequency and intensity, temperature and current, etc., so that users can find and deal with the fault points in time, increase the monitoring efforts, reduce the size of the fault, and avoid serious damage to the power rotating equipment 10 and the inconvenience caused by long-term downtime maintenance.

[0054] In one embodiment, see [reference] Figure 2 As shown, the fault prediction device for the power rotating equipment 10 also includes a mounting assembly 60, which includes an assembly ring 61, an elastic element 62, and a damping ring 63. The assembly ring 61 is sleeved on the vibration sensor 20; the elastic element 62 connects the assembly ring 61 and the machine cover 12; the elastic element 62 is used to provide a pulling force to the assembly ring 61 toward the support member 13, so that the assembly ring 61 has a tendency to move toward the support member 13; the damping ring 63 is sleeved on the assembly ring 61 and connected to the machine cover 12.

[0055] Thus, by fitting the assembly ring 61 onto the vibration sensor 20, a clearance fit is achieved between the vibration sensor 20 and the housing 12. By fitting the damping ring 63 onto the assembly ring 61, the damping ring 63 connects to the housing 12. In other words, the damping ring 63 provides vibration damping between the assembly ring 61 and the housing 12, reducing the impact of environmental factors on the monitoring accuracy of the vibration sensor 20. By connecting the assembly ring 61 and the housing 12 with the elastic element 62, the elastic element 62 provides tension to the assembly ring 61 towards the support member 13, causing the assembly ring 61 to tend to move towards the support member 13. This ensures reliable contact between the vibration sensor 20 and the support member 13, preventing the vibration sensor 20 from loosening due to environmental vibrations and other factors, thereby improving the monitoring accuracy of the vibration sensor 20.

[0056] Understandably, the damping ring 63 can be made of rubber. The elastic element 62 can be a tension spring.

[0057] In one embodiment, see [reference] Figure 1 As shown, the monitoring mechanism 50 includes a cabinet 51, a processing module (not shown), an alarm module (not shown), and a power supply module (not shown). The processing module is located inside the cabinet 51; the alarm module is located inside the cabinet 51; the alarm module is electrically connected to the processing module; the power supply module is connected to both the processing module and the alarm module; the cabinet 51 is provided with a terminal block 52 that is electrically connected to the processing module, and the terminal block 52 is connected to the vibration sensor 20, the current transformer 30, and the temperature sensor 40.

[0058] In this way, the processing module can predict the faults of the power rotating equipment 10 based on the monitored vibration frequency and intensity, temperature and current values. If at least one of the monitored vibration frequency, vibration intensity, temperature and current reaches the alarm requirements, the processing module controls the alarm module to sound an alarm, which makes it easier for users to find and deal with the fault points in a timely manner, increases the monitoring efforts, reduces the size of the fault, and avoids serious damage and the inconvenience of long-term downtime for maintenance.

[0059] Furthermore, the vibration sensor 20, the current transformer 30, and the temperature sensor 40 can all be connected to the terminals on the terminal block via wires.

[0060] In one embodiment, see [reference] Figure 1 , Figure 3 As shown, the cabinet 51 is also provided with a transmission slot 53 and a power slot 54; the transmission slot 53 is provided with a transmission interface (not shown), which is electrically connected to the processing module; the cabinet 51 is provided with a first sliding groove 55 communicating with the transmission slot 53, and a first sliding cover 56 is slidably connected in the first sliding groove 55, which is used to close or open the transmission slot 53; the power slot 54 is provided with a power interface (not shown); the power interface is electrically connected to the power module; the cabinet 51 is provided with a second sliding groove 57 communicating with the power slot 54; a second sliding cover 58 is slidably connected in the second sliding groove 57, which is used to close or open the power slot 54.

[0061] In this way, by embedding the transmission interface and power interface separately in the slot with independent sliding covers, when multiple monitoring agencies 50 need to be connected together, only the first sliding cover 56 needs to be slid to expose the transmission interface for data communication, and the second sliding cover 58 needs to be slid to turn on the power. This avoids dust intrusion or accidental damage caused by exposed interfaces, and ensures that various external devices can be quickly plugged in and out for adaptation. It is especially suitable for scenarios that require frequent switching of monitoring terminals, and greatly reduces the complexity and time cost of device docking.

[0062] In one embodiment, see [reference] Figure 1 , Figure 3 and Figure 4As shown, it also includes a connection structure 70 for connecting two monitoring mechanisms 50. The connection structure 70 includes a connection plate 71, a transmission connector 72, two sets of power plugs 73, and a switching lever 74. The connection plate 71 is disposed between the two monitoring mechanisms 50. A switching groove 71a is provided on the connection plate 71. The switching groove 71a passes through one side of the connection plate 71 along a direction perpendicular to its thickness. The transmission connector 72 passes through the connection plate 71 along its thickness. The transmission connector 72 is used to connect the transmission interfaces on the two monitoring mechanisms 50. The two sets of power plugs 73 are disposed on the connection plate 71 along its thickness. Two sets of power plugs 73 are located on both sides of the two monitoring mechanisms 50; a switching block 74 is disposed in the switching slot 71a, and a first power connection rod assembly 75 and a second power connection rod assembly 76 are disposed on the switching block 74; the first power connection rod assembly 75 and the second power connection rod assembly 76 are spaced apart; the switching block 74 can move along the switching slot 71a to a first position and a second position; when the switching block 74 is in the first position, the first power connection rod assembly 75 is used for normal connection of the two sets of power plugs 73; when the switching block 74 is in the second position, the second power connection rod assembly 76 is used for staggered connection of the two sets of power plugs 73.

[0063] Specifically, in the appendix Figure 3 From the perspective shown, two monitoring mechanisms 50 are stacked, and a connecting plate 71 is horizontally positioned between them. The two ends of the transmission connector 72 on the connecting plate 71 are respectively inserted into the two transmission interfaces on the two monitoring mechanisms 50, and two sets of power plugs 73 are respectively inserted into the two power interfaces on the two monitoring mechanisms 50. This causes the switching block 74 to move within the switching slot 71a, placing it in the first position. The first conductive rod assembly on the switching block 74 connects to the two sets of power connectors, enabling normal connection of the two sets of power plugs 73. Of course, when the power modules of the two monitoring mechanisms 50 are inconsistent, the switching block 74 can be switched to the second position, connecting the second conductive rod assembly to the two sets of power connectors, achieving staggered connection of the two sets of power plugs 73. This allows the power modules in the two monitoring mechanisms 50 to be connected in series, preventing the limitation of power module usage due to parallel connection of power modules with inconsistent power module conditions.

[0064] It should be noted that, for reference Figure 4 As shown, each set of power plugs 73 includes a positive plug 73a and a negative plug 73b.

[0065] In one example, see Figure 4As shown, the first power connection rod assembly 75 includes a first positive power connection rod 751 and a first negative power connection rod 752 spaced apart. The first positive power connection rod 751 and the first negative power connection rod 752 are inserted through the switching block 74 along the thickness direction of the connecting plate 71. When the switching block 74 is in the first position, the first positive power connection rod 751 is connected to the two positive plugs 73a of the two sets of power plugs 73, and the first negative power connection rod 752 is connected to the two negative plugs 73b of the two sets of power plugs 73, thereby realizing the normal connection of the two power plugs 73.

[0066] In one example, the second terminal assembly 76 includes two second positive terminal terminals 761 and two second negative terminal terminals 762; the two second positive terminal terminals 761 and two second negative terminal terminals 762 are arranged in a rectangular pattern on the switching block 74; one second positive terminal terminal 761 and one second negative terminal terminal 762 are located on one side of the switching block 74 along the thickness direction of the connecting plate 71; the other second positive terminal terminal 761 and the other second negative terminal terminal 762 are located on the other side of the switching block 74 along the thickness direction of the connecting plate 71; the two second positive terminal terminals 761 are diagonally distributed, and the two second positive terminal terminals are connected to the other side of the switching block 74. The rods 761 are interconnected; the two second negative terminal rods 762 are diagonally distributed and interconnected; when the switching block 74 is in the second position, one second positive terminal rod 761 is connected to the positive plug 73a of a set of power plugs 73, and the other second positive terminal rod 761 is connected to the negative plug 73b of another set of power plugs 73; one second negative terminal rod 762 is connected to the negative plug 73b of a set of power plugs 73, and the other second negative terminal rod 762 is connected to the positive plug 73a of another set of power plugs 73, thereby realizing the staggered connection of the two sets of power plugs 73.

[0067] In one embodiment, see [reference] Figure 1 , Figure 3 and Figure 4 As shown, a plurality of heat dissipation holes 71b are provided at intervals on the connecting plate 71, and the heat dissipation holes 71b penetrate the connecting plate 71 along the direction perpendicular to the thickness of the connecting plate 71; a heat conduction structure 80 is provided on the connecting plate 71, and the heat conduction structure 80 is used to conduct the heat of the monitoring mechanism 50 to the heat dissipation holes 71b.

[0068] Thus, during operation, the heat-conducting structure 80 can quickly conduct the heat of the monitoring mechanism 50 laterally to the heat dissipation holes 71b group. The multiple heat dissipation holes 71b serve as heat dissipation channels, which can dissipate the heat to the outside in a timely manner, achieving effective heat dissipation of the monitoring mechanism 50. This can significantly improve the thermal management efficiency of the monitoring mechanism 50 and avoid false alarms or component aging caused by overheating.

[0069] In one embodiment, see [reference] Figure 4As shown, the heat-conducting structure 80 includes a heat-conducting patch 81, a heat-dissipating ring 82, and a heat-dissipating rod 83. The heat-conducting patch 81 is disposed on both sides of the connecting plate 71 along its own thickness direction, and the heat-conducting patch 81 is used to fit against the monitoring mechanism 50 on the corresponding side. The heat-dissipating ring 82 is disposed inside the heat dissipation hole 71b. The heat-dissipating rod 83 is disposed on the connecting plate 71, and the heat-dissipating rod 83 connects the heat-conducting patch 81 and the heat-dissipating ring 82.

[0070] In this way, the heat from the two monitoring units 50 can be conducted to the heat dissipation rod 83 through the corresponding thermal conductive pads 81. The heat dissipation rod 83 acts as a longitudinal thermal bridge to quickly transfer the heat to the heat dissipation ring 82 embedded in the heat dissipation hole 71b. The heat dissipation ring 82 increases the heat dissipation area in the heat dissipation hole 71b. The heat is quickly dissipated through the convection of multiple heat dissipation holes 71b with the outside air, thereby achieving rapid heat dissipation of the monitoring unit 50 and ensuring that the monitoring unit 50 can work continuously and stably under high temperature conditions.

[0071] In one embodiment, see [reference] Figure 5 As shown, it also includes a tap bar 90 and an air guide drive 100. The tap bar 90 is provided with a flow channel (not shown), and the tap bar 90 is provided with multiple interfaces 91 that communicate with the flow channel. The interfaces 91 are used to communicate with the heat dissipation holes 71b. The air guide drive 100 is connected to the flow channel and is used to exhaust the heat in the heat dissipation holes 71b.

[0072] In this way, the heat in the multiple heat dissipation holes 71b can be discharged in time through the tap 90 and the air guide drive 100, thereby realizing the rapid heat dissipation of the monitoring mechanism 50 and ensuring that the monitoring mechanism 50 can work continuously and stably under high temperature conditions.

[0073] It should be noted that the air guide drive component 100 can be a component that serves a ventilation function, such as an air pump or a fan. The interface 91 on the tap bar 90 can be connected to the heat dissipation hole 71b via a pipe.

[0074] In one embodiment, see [reference] Figure 6 As shown, it also includes a connecting pipe 110 and a sealing ring 120. The connecting pipe 110 is used to connect to the heat dissipation hole 71b on the connecting plate 71; the sealing ring 120 is sleeved on the connecting pipe 110, and the sealing pipe is used for the sealing connection between the connecting pipe 110 and the heat dissipation hole 71b.

[0075] In this way, the heat dissipation holes 71b on multiple connecting plates 71 can be connected by connecting pipe 110, and the heat dissipation hole 71b on one connecting plate 71 can be connected to the tap bar 90 and the air guide drive component 100 by connecting pipe 110. In this way, the heat from multiple heat dissipation holes 71b on multiple connecting plates 71 can be discharged in time, realizing rapid heat dissipation of multiple monitoring mechanisms 50 and ensuring that multiple monitoring mechanisms 50 can work continuously and stably under high temperature conditions.

[0076] Understandably, the sealing ring 120 is made of materials including rubber.
