[0002] The thermal power plant operation safety monitoring and early warning device is a device specifically used to monitor and warn of potential dangers or abnormal conditions in the operation of thermal power plants. The device is mainly used in the industrial production process of thermal power plants, through real-time monitoring of equipment status such as turbine operation status, generator electrical equipment status, etc., as well as personnel behavior such as entering prohibited areas and abnormal operation behavior. The device uses sensors and cameras and other equipment to obtain data, and analyzes and judges through advanced algorithms. When an abnormal situation is detected, the system can promptly issue an alarm or take preset safety measures, such as notifying the operator, to ensure the safe operation of the thermal power plant and the safety of personnel.

This patent mainly uses a control box, a connecting plate is fixedly installed on the top of the control box, a mounting seat is fixedly installed on the top of the connecting plate, a fan box is fixedly installed on the top of the control box, the fan box is located on the front side of the connecting plate, the front inner wall and the rear inner wall of the fan box are rotatably installed with the same second rotating shaft, a protective box is fixedly installed on the top of the right side of the control box, a motor is fixedly installed on the left inner wall of the control box, and a reciprocating mechanism is arranged on the motor output shaft; a support rod is fixedly installed on the right side of the control box, the support rod is located below the protective box, and the first rotating shaft is rotatably installed on the support rod.

[0004] However, in thermal power plants, environmental conditions are usually harsh, with a large amount of dust, smoke and other pollutants. In such an environment, monitoring equipment, especially cameras, are easily affected because they need to be kept clean to provide clear monitoring images; therefore, ensuring the cleanliness of cameras is crucial to the normal operation of the monitoring system; however, since thermal power plants are usually large and complex facilities, monitoring equipment is widely distributed and difficult to access, and manual cleaning of cameras is difficult and risky, so the lack of automatic cleaning function in cameras will increase the difficulty and cost of maintenance. In order to improve the stability and reliability of safety monitoring and early warning devices, consideration should be given to adding an automatic cleaning function to the camera to reduce manual intervention and ensure the long-term and effective operation of the monitoring system.

[0005] Therefore, we propose a thermal power plant operation safety monitoring and early warning device. Utility Model Content

A second connecting member 7 is fixedly connected to the bottom end of the camera 4, and a second mounting seat 8 is fixedly connected to one end of the second connecting member 7 away from the camera 4. An alarm 9 is provided at one end of the second mounting seat 8 away from the second connecting member 7, and a sensor 10 is provided at one end of the alarm 9 away from the second mounting seat 8. The first mounting seat 1 is made of high-strength metal material, such as aluminum alloy or stainless steel, to ensure the stable fixation and reliable operation of the motor 2. In a thermal power plant, this high-strength material can withstand harsh working environment and temperature changes, and ensure the durability and stability of the equipment.

[0025] A plurality of second screw holes are provided on the first mounting seat 1, and the second screw holes are evenly distributed on the first mounting seat 1. A plurality of third screw holes are provided on the upper surface of the slide rail 11, and the positions and sizes of the third screw holes are consistent with those of the second screw holes. This screw hole design enables the equipment to be flexibly installed and adjusted in a thermal power plant, thereby improving the efficiency of maintenance and overhaul.

[0026] A rubber scraper is provided on the side of the scraper 16 close to the camera 4. The length of the rubber scraper is consistent with the length of the scraper 16. The rubber material can provide good sealing performance to ensure the cleaning effect of the scraper 16 on the camera 4. The alarm 9 includes a shell, which is cylindrical and made of plastic. In the environment of a thermal power plant with a lot of dust and pollutants, this design can maintain the clarity of the camera 4, thereby ensuring the monitoring effect. The alarm 9 is used to issue an alarm in time when an abnormal situation occurs in the thermal power plant, reminding the staff to take corresponding measures, thereby improving the operating safety of the thermal power plant.

[0027] The first screw holes are symmetrically distributed on the electric push rod base 12. The end of the piston rod 15 away from the electric push rod 13 is fixedly connected to the center position of the scraper 16, which can ensure the uniform force transmission of the scraper 16 during the pushing process. The motor 2, camera 4, speaker 5, alarm 9, sensor 10, and electric push rod 13 are all electrically connected to the controller 6. In the thermal power plant, the controller 6 ensures the coordinated operation and timely response of the equipment by real-time monitoring and control of various components, thereby improving the reliability and safety of the entire system.

[0028] Working principle: First, after the controller 6 receives the instruction to rotate the camera 4, it will send a signal to the motor 2. After receiving the signal, the motor 2 starts to work and transmits power through the first connecting member 3 fixedly connected to its output end. The first connecting member 3 transmits the power to the camera 4, so that the camera 4 rotates around the vertical axis under the drive of the motor 2, changing the monitoring direction and range, thereby covering more monitoring areas, including key equipment and pipelines. If the monitoring screen is blocked or contaminated, such as affected by dust or smoke, the controller 6 will receive a signal. When the controller 6 receives the signal of the abnormal situation detected by the camera 4, it will determine whether it is necessary to start the cleaning program; if cleaning is required, the controller 6 will send a signal to the electric push rod 13. After the electric push rod 13 receives the signal, the activity inside it will be activated. The piston rod 15 then extends forward, and the scraper 16 fixed on the piston rod 15 moves to the front of the camera 4. The rubber scraper of the scraper 16 is close to the monitoring screen to remove obstructions or dirt, such as dust or oil. After the cleaning is completed, the scraper 16 returns to its original position and the monitoring screen becomes clear again, thereby ensuring the effectiveness of the monitoring system; if the sensor 10 detects other abnormal conditions, such as abnormal temperature or pressure, the controller 6 will trigger the alarm 9 to send an alarm signal, which is crucial for the safe operation of the thermal power plant, because abnormal temperature and pressure may indicate equipment failure or potential safety hazards; at the same time, the controller 6 can also send a signal to the speaker 5 to play the corresponding sound information to remind the operator to pay attention to the abnormal situation, so as to take corresponding measures in time to ensure the safe and stable operation of the thermal power plant.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
