This device improves the problem that most auxiliary early warning devices for centralized control operation of thermal power plants are fixed installations and cannot cover hidden areas such as the back of equipment and pipe gaps, making it difficult to detect hidden dangers such as leaks and overheating in a timely manner.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an auxiliary early warning device for centralized control operation of a thermal power plant, comprising:

[0008] A panoramic camera, which is fixedly connected to the lower end of the rotating rod;

[0009] A drive mechanism is provided on one side of the panoramic camera to enable the panoramic camera to rotate.

[0010] Preferably, the drive mechanism includes a motor, a first gear, a fixed frame, a rack, a second gear, a connecting rod, a rack, a third gear, a fourth gear, and a fifth gear. The motor is located below the mounting block. The first gear is fixedly connected to the output shaft of the motor. The fixed frame is fixedly connected to the lower end of the mounting block. The rack is sleeved on the circumferential surface of the first gear. The second gear is sleeved on the inner wall of the rack. The first and second gears mesh with the rack.

The connecting rod 10 is fixedly connected to one side of the second gear 9. The third gear 11 is fixedly connected to the circumferential surface of the second gear 9. The rack 4 is rotatably connected inside the mounting block 1. The rack 4 and the third gear 11 are in contact and mesh. The fourth gear 12 is fixedly connected to the circumferential surface of the rack 4. The fifth gear 13 is fixedly connected to the circumferential surface of the rotating rod 2. A 360° no-dead-angle rotating scan is achieved through the panoramic camera 3. This not only overcomes the problem of blind spots in traditional fixed cameras but also greatly improves the monitoring range and real-time performance.

[0033] In this embodiment: the mounting block 1 provides support for the rotating rod 2 and the rack 4, and has an internal limit groove that cooperates with the limit blocks on the rotating rod 2 and the rack 4, so that they can only rotate and cannot move up and down. The rotating rod 2 is used to install and drive the panoramic camera 3 to rotate. The panoramic camera 3 is used to monitor the operating environment of the central control area of ​​the thermal power plant in real time. The motor 5 serves as the power source for driving the first gear 6 to rotate. The first gear 6 is used to transmit the power of the motor 5 to the rack 8. The fixing frame 7 is used to support the rack 8. The rack 8 meshes with the first gear 6 and the second gear 9, and is used to transmit the rotational power of the first gear 6 to the second gear 9, thereby driving the second gear 9 to rotate. The second gear 9 is used to drive the connecting rod 10 to rotate. The connecting rod 10 is used to drive the third gear 11 to rotate. The third gear 11 drives the rack 4 to rotate. The rack 4 drives the fourth gear 12 to rotate. The fourth gear 12 is used to transmit the rotational motion of the rack 4 to the fifth gear 13. The fifth gear 13 is used to drive the rotating rod 2 to rotate.

[0034] Please refer to the details. Figure 1-4 A mounting plate 14 is fixedly connected to one side of the mounting block 1, and the surface of the mounting plate 14 has multiple threaded holes 15.

[0035] In this embodiment: the mounting plate 14 is used to open threaded holes 15. The threaded holes 15 can be fixed in different positions according to actual installation requirements.

[0036] Please refer to the details. Figure 1-4 A connecting block 16 is fixedly connected to the lower end of the motor 5, and the connecting block 16 is fixedly connected to the surface of the mounting plate 14.

[0037] In this embodiment: the connecting block 16 is fixedly connected to the lower end of the motor 5 and fixedly connected to the surface of the mounting plate 14 to enhance the stability of the motor 5.

[0038] Please refer to the details. Figure 1-4 The first alarm 17 is fixedly connected to the surface of the mounting plate 14, and the first alarm 17 is connected to the panoramic camera 3.

[0039] In this embodiment: when the panoramic camera 3 detects an abnormal situation in the central control area of ​​the thermal power plant, it transmits the signal to the first alarm 17. The first alarm 17 can detect the abnormal situation at the first time and quickly issue an alarm, which improves the speed and efficiency of responding to emergencies. The first alarm 17 combines sound and visual alarm methods, which can effectively convey emergency information in noisy environments or for hearing-impaired staff.

[0040] Please refer to the details. Figure 1-4 A smoke sensor 18 is fixedly connected to the surface of the mounting plate 14, and a second alarm 19 is fixedly connected to the surface of the mounting plate 14. The smoke sensor 18 and the second alarm 19 are connected by signals.

[0041] In this embodiment: the smoke sensor 18 is used to monitor the smoke concentration in the central control area of ​​the thermal power plant in real time. The second alarm 19 is connected to the smoke sensor 18 and can immediately activate the alarm when smoke is detected. The second alarm 19 can be an audible and visual alarm, including a buzzer and a flashing light, so as to attract the attention of the staff in the event of a fire. The color is different from the first alarm 17, so that the staff can quickly identify it. It should be noted that the panoramic camera 3, the first alarm 17, the smoke sensor 18 and the second alarm 19 are all existing technologies, and will not be described in detail in this article.

[0042] Please refer to the details. Figure 1-4 A handle 20 is fixedly connected to the upper end of the mounting block 1.

[0043] In this embodiment: the handle 20 provides a gripping point for personnel to install the device, making it convenient for personnel to install.

[0044] When the motor 5 of this device is powered on, it drives the first gear 6 to rotate. The first gear 6 meshes with the rack 8, pushing the rack 8 to move laterally, which in turn drives the second gear 9 to rotate. The second gear 9 drives the third gear 11 to rotate through the connecting rod 10. The third gear 11 meshes with the rack 4, causing the rack 4 to rotate. The rack 4 meshes with the fourth gear 12 and the fifth gear 13, ultimately driving the rotating rod 2 and the panoramic camera 3 to perform a 360° rotation scan. During the rotation, the panoramic camera 3 captures the environment of the power plant's central control area in real time. It detects equipment abnormalities through image recognition technology. If the panoramic camera 3 detects an abnormality, it immediately triggers the first alarm 17, activating an audible and visual alarm to alert the operator. At the same time, the smoke sensor 18 independently monitors the ambient smoke concentration. If the smoke concentration exceeds the standard, it directly triggers the second alarm 19, creating a differentiated warning from the first alarm 17. Through gear transmission, the camera achieves 360° rotation without blind spots, covering the blind spots of traditional fixed cameras and improving the monitoring range and real-time performance.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
