Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a regulator monitoring device for generators. Background Technology

[0002] Generators, as core equipment in power systems, are widely used in industry, energy, transportation, and other fields. Their regulators are key components that control the stability of the generator's output voltage, maintaining it within a set range by adjusting the excitation current. A regulator malfunction can lead to excessively high or low output voltage, causing equipment damage, power system fluctuations, or even power outages.

[0003] Traditional solutions focus on only one or a few parameters, ignoring the interrelationship of multiple parameters such as voltage, current, and temperature. This makes it impossible to accurately determine the overall state of the regulator. At the same time, the regulator generates a lot of heat during long-term high-load operation. Traditional structures have simple heat dissipation hole designs without active heat dissipation, which can easily lead to performance degradation and shortened lifespan due to component overheating. Utility Model Content

[0004] This utility model mainly provides a generator regulator monitoring device that can determine the overall status of the regulator and dissipate heat from the regulator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a generator regulator monitoring device, comprising: a regulator body, a top cover embedded in the top of the regulator body, a fixing plate fixedly connected to the bottom of the top cover near the center, a voltage sensor, a current sensor, and a temperature sensor being embedded and fixedly connected at equal intervals at the bottom of the fixing plate, heat dissipation holes being opened at equal intervals at one end of the regulator body, a square hole being opened at the other end of the regulator body, a mesh plate being fixedly connected to the inside of the square hole near both sides, a fixing member being symmetrically fixedly connected to the inside of the square hole, a drive motor being embedded and fixedly connected to the center of the fixing member, and a fan blade being fixedly connected to the output end of the drive motor.

[0007] Preferably, soft pads are fixedly connected to the bottom of both the regulator body and the mounting plate. This arrangement can effectively reduce the vibration of the regulator body.

[0008] Preferably, mounting slots are symmetrically formed on the top of the regulator body and at both ends of the top cover. Mounting blocks are embedded inside the mounting slots, and the mounting blocks are fixedly connected to the top cover. With the above arrangement, the top cover can be installed and fixed.

[0009] Preferably, an alarm light is installed on the front of the regulator body near the center. This setting can serve to issue an alarm when an abnormality is detected.

[0010] Preferably, the bottom of the top cover is fixedly connected to fins at equal intervals on both sides of the fixed plate. This arrangement can increase the heat exchange area.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model integrates voltage, current, and temperature sensors to collect key operating parameters of the regulator in real time, covering electrical performance and thermal status. Through multi-parameter correlation analysis, it accurately identifies abnormalities. At the same time, when an abnormality occurs, it can be alarmed by an alarm light to provide early warning of potential faults, support preventive maintenance, and reduce downtime losses.

[0013] 2.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a generator regulator monitoring device, comprising: a regulator body 1, a top cover 4 embedded in the top of the regulator body 1, a fixing plate 5 fixedly connected to the bottom of the top cover 4 near the center, a voltage sensor 6, a current sensor 7, and a temperature sensor 8 equally spaced and fixedly connected to the bottom of the fixing plate 5, heat dissipation holes 12 equally spaced at one end of the regulator body 1, a square hole 13 at the other end of the regulator body 1, a mesh plate 14 fixedly connected inside the square hole 13 near both sides, a fixing member 15 symmetrically fixedly connected inside the square hole 13, and a drive motor 1 embedded and fixedly connected to the center of the fixing member 15. 6. The output end of the drive motor 16 is fixedly connected to the fan blade 17. Through the above settings, the voltage sensor 6, current sensor 7, and temperature sensor 8 can monitor the voltage, current signals, and component temperature of the regulator circuit, respectively, and convert the physical quantities into electrical signals to be transmitted to the built-in controller (which needs to be external or integrated, depending on the system design). The drive motor 16 drives the fan blade 17 to rotate, drawing in external cold air through the mesh plate 14 into the regulator body 1, flowing through the sensors, circuit boards, and other heat-generating components, and then being discharged through the heat dissipation holes 12. The fin plate 18 is attached to the bottom of the top cover 4, quickly conducting the heat absorbed by the top cover 4 to the outside, achieving the effect of active or passive synergistic heat dissipation.

[0022] like Figure 1 As shown, mounting plates 2 are fixedly connected to both ends of the regulator body 1 and near the bottom. Mounting holes are opened on the surface of the mounting plates 2. With the above settings, the regulator body 1 can be installed and fixed.

[0023] like Figure 2 As shown, soft pads 3 are fixedly connected to the bottom of both the regulator body 1 and the mounting plate 2. Through the above-mentioned arrangement, the regulator body 1 can be shock-absorbing.

[0024] like Figure 3 and Figure 4 As shown, mounting slots 9 are symmetrically opened on the top of the regulator body 1 and at both ends of the top cover 4. Mounting blocks 10 are embedded inside the mounting slots 9, and the mounting blocks 10 are fixedly connected to the top cover 4. Through the above settings, the top cover 4 can be installed and fixed.

[0025] like Figure 4As shown, an alarm light 11 is installed on the front of the regulator body 1 near the center. With the above setting, an alarm can be triggered when an abnormality is detected.

[0026] like Figure 3 As shown, the bottom of the top cover 4 and the two sides of the fixing plate 5 are fixedly connected to the fins 18 at equal intervals. Through the above arrangement, the heat exchange area can be increased.

[0027] The device's operation and working principle are as follows: Voltage sensor 6, current sensor 7, and temperature sensor 8 monitor the voltage, current signals, and component temperatures of the regulator circuit, respectively. They convert physical quantities into electrical signals and transmit them to the built-in controller (which may require external connection or integration, depending on the system design). The drive motor 16 rotates the fan blades 17, drawing in external cold air through the mesh plate 14 into the regulator body 1. The air flows through the sensors, circuit boards, and other heat-generating components, and is then discharged through the heat dissipation holes 12. The fins 18 are attached to the bottom of the top cover 4, quickly transferring the heat absorbed by the top cover 4 to the outside, achieving active or passive coordinated heat dissipation to maintain a stable internal temperature. The controller receives sensor data and compares it with the preset normal threshold. If the parameters are out of range (such as voltage too high / too low, temperature exceeding the standard), the alarm light 11 is triggered to provide an audible and visual warning. At the same time, the data trend is analyzed, and a warning signal is generated for slow anomalies (such as gradual temperature changes) and pushed to the maintenance terminal (communication module needs to be expanded). The device is fixed to the generator or bracket through the mounting plate 2, mounting holes and bolts. The soft pad 3 buffers vibration and protects the internal components. The top cover 4 is embedded into the mounting slot 9 through the mounting block 10 to achieve quick disassembly and assembly, which is convenient for sensor calibration and equipment maintenance.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
