Description

Technical Field

[0001] The utility model relates to the technical field of thermal inspection of power plants, in particular to an expanded thermal inspection device for power plants. Background Art

[0002] The daily work of thermal power plant thermal operation and maintenance inspection engineers is to conduct regular inspections, check the daily use and maintenance of equipment, check the operation of on-site equipment, various safety measures and the status of protective devices, and report abnormal situations in a timely manner. In case of emergency, refer to the emergency plan for handling. Thermal operation and maintenance inspection is a very important and tedious job. There can be no mistakes. Newcomers are prone to misdetection and missed detection. They also lack the necessary ability to identify abnormal situations and the ability to handle emergency plans for emergency situations, which brings hidden dangers to the safe operation of thermal power plants.

[0003] Statistics of thermal accidents in power plants at home and abroad show that primary instrument disconnection, short circuit and other faults account for 26.3%, human operation errors account for 20%-25%, thermal power supply failures account for 10%, secondary instrument failures such as thermal regulation failure account for 21.4%, and actuator failures account for 8%. Therefore, by improving the quality of thermal personnel, scientifically inspecting and patrolling important thermal instruments, equipment and their important accessories, and estimating the life of important thermal primary and secondary circuits and early warning, thermal accidents can be effectively reduced. To this end, domestic and foreign scholars have done a lot of research on thermal inspections in thermal power plants, thermal data mining in thermal power plants, and equipment life estimation, and have achieved good results. The thermal inspection point inspection intelligent management system has gone through three processes: the research and development of inspection point auxiliary equipment, the digital management of inspection points, and the intelligent management of inspection points. It is currently in the development stage of intelligent management of inspection points. Thermal inspection and data reporting in power plants is not a random work behavior, but a work behavior with clear goals of thermal defect discovery, thermal equipment life estimation and early warning. However, errors and omissions in the location, position and data type of data entry will not only lead to anomalies in the thermal inspection data of the power plant and mislead the inspection data judgment, but also make it easy to ignore the abnormal phenomena of important inspection equipment in the power plant, resulting in insufficient efficiency of the inspection data.

[0030] Figure 1-Figure 6 The structure diagram of an embodiment of an expandable thermal inspection device for a power plant according to the utility model is shown in FIG. Figure 1-Figure 6 In this embodiment, an expandable thermal inspection device for a power plant is provided, and its main body includes a collection component 100, a wireless gateway 200 and a field server 300.

[0031] The acquisition component 100 includes a bus-type vibration probe 110 , a bus-type infrared temperature measurement probe 120 , a TCP audio acquisition probe 130 and a TCP camera 140 .

[0032] The wireless gateway 200 is connected to the bus-type vibration probe 110, the bus-type infrared temperature probe 120, the TCP audio acquisition probe 130 and the TCP camera 140 through the interface 230, and the wireless gateway 200 has a temperature and humidity probe 210;

[0033] The on-site server 300 is wirelessly connected to the wireless gateway 200 via wifi, and is used to analyze and store the data transmitted by the wireless gateway 200.

[0034] In this embodiment, the wireless gateway 200 has two TCP interfaces, which respectively collect the video files of the TCP camera 140 and the audio files of the TCP audio acquisition probe 130, and one RS485 port, which respectively collects the data of the bus-type vibration probe 110 and the bus-type infrared temperature measurement probe 120, as well as the switching quantities of the bus-type vibration probe 110, the bus-type infrared temperature measurement probe 120, the TCP audio acquisition probe 130 and the TCP camera 140.

[0035] The field server 300 and the wireless gateway 200 are both shoulder-carrying. The entire device transmits data wirelessly, which is convenient for the user to hold the field server 300 in one hand and the bus-type vibration probe 110, bus-type infrared temperature probe 120, TCP audio acquisition probe 130 and TCP camera 140 in the other hand to collect data, and there is no physical connection between the two. In addition, the wireless gateway 200 is equipped with a first probe 220 that can read RFID tags at a distance of 0-10m, which is used to read the location information of RFID tags at a distance of 0-10m. The bus-type vibration probe 110 is equipped with a short-range RFID tag reading probe 110a, which is used to accurately identify the RFID tags of the equipment collecting data in the area and the RFID tags that need to be accurately located to collect data.

Double-clicking the button can cancel data entry. Before audio collection, the short-range RFID tag reading probe 110a of the bus-type vibration probe 110 is used to read the serial number and exact position of the audio to be collected. Then, the front longitudinal audio is collected through the collection tube with a mute effect, and the membrane collection probe is used to amplify the audio.

Double-clicking the fourth button 140c can cancel data entry. Before entering video data, the device serial number or location serial number of the video to be collected needs to be read through the first probe 220 of the wireless gateway 200.
