[0002] New energy units refer to a combination of equipment that uses renewable energy to generate electricity. Wind turbines are a common type of new energy unit. They use wind power to drive the wind wheel to rotate, and then drive the generator to generate electricity. The energy efficiency status of existing new energy units is generally determined based on the monitoring data of the generator status, and the generator status monitoring requires the use of a monitoring device.

[0003] In the existing technology, the existing energy efficiency status monitoring device of the new energy unit can monitor the status of the generator in real time during actual use, but it only has the function of data monitoring, and does not have the function of external image monitoring, that is, the method of relying solely on various data monitoring means to judge the status of the generator is relatively limited. When damage or cracks appear on the surface of the generator shell, due to the lack of the generator external image monitoring function, the monitoring personnel will not be able to find the problem in advance through the monitoring device. At this time, the damage to the surface of the shell that continues to be used may gradually worsen, thereby affecting the use effect of the generator, and then affecting the power generation efficiency, which not only reduces the use effect of the monitoring device, but also reduces the use efficiency of the monitoring device.

[0029] In the present invention, when it is necessary to monitor the status of the generator 1, the communication module 209 is first connected to the monitoring equipment in the monitoring room through the prepared wire, and then the controller 413 is connected to the external power supply through the prepared power line, and the power module 211 is connected to the power supply equipment with wires, and then the monitoring equipment, wires, power module 211 and communication module 209 in the monitoring room are used to set the vibration threshold and temperature threshold on the data analysis and comparison module 210 to turn on the controller 413, and then the monitoring equipment, wires and communication module 209 in the monitoring room are used to turn on the controller 413, and the basic use program is set and some image data is stored in the controller 413 (the shell of the generator 1 When everything is ready, the new energy unit is directly used for power generation operation. At this time, the monitoring personnel can use the monitoring equipment and monitoring mechanism in the monitoring room to monitor the status of the generator 1 when it is in use. When the generator 1 starts to be used, each temperature sensor 206 and each vibration sensor 207 will perform temperature monitoring and vibration monitoring on the generator 1. Then each temperature sensor 206 and each vibration sensor 207 will transmit the monitored temperature data and vibration data to the data acquisition module 208. Then the data acquisition module 208 will perform signal conditioning on each received temperature data and each vibration data, and then transmit it to the data analysis and comparison module 210. When the data analysis and comparison When module 210 receives each temperature data and each vibration data, at this time, the data analysis and comparison module 210 will compare each temperature data and each vibration data with the temperature threshold value and vibration threshold value set in advance by the data analysis and comparison module 210 respectively. When all the temperature data received by the data analysis and comparison module 210 are lower than the temperature threshold value set in advance by the data analysis and comparison module 210, it means that the working state of the generator 1 is normal. At this time, the data analysis and comparison module 210 will directly transmit the monitoring results to the monitoring equipment in the monitoring room through the cooperation of the communication module 209 and the wire for the monitoring personnel to watch and understand. When the data analysis and comparison module 210 receives a temperature data in all the temperature data that is lower than the temperature threshold value set in advance by the data analysis and comparison module 210, it means that the working state of the generator 1 is normal. At this time, the data analysis and comparison module 210 will directly transmit the monitoring results to the monitoring equipment in the monitoring room through the cooperation of the communication module 209 and the wire for the monitoring personnel to watch and understand. When the temperature threshold value pre-set by block 210 is high, it means that there is a problem with generator 1. At this time, the data analysis and comparison module 210 will directly transmit the monitoring results to the monitoring equipment in the monitoring room through the cooperation of the communication module 209 and the wire for the monitoring personnel to watch and understand. When the monitoring personnel see the monitoring results of generator 1, the monitoring personnel will send someone to check. When all the vibration data received by the data analysis and comparison module 210 are lower than the vibration threshold value pre-set by the data analysis and comparison module 210, it means that the working state of generator 1 is normal. At this time, the data analysis and comparison module 210 will directly transmit the monitoring results to the monitoring equipment in the monitoring room through the cooperation of the communication module 209 and the wire for the monitoring personnel to watch and understand.When one vibration data among all the vibration data received by the data analysis and comparison module 210 is higher than the vibration threshold value set in advance by the data analysis and comparison module 210, it means that there is a problem with the generator 1.

When the monitoring mechanism 2 starts to be used, the monitoring equipment, wires, communication module 209 and controller 413 in the monitoring room are used to start the fan 305. At this time, the started fan 305 will, with the cooperation of the T-shaped hole 301, first place the shell 2 placed in the shell 2 02 and the perforated shell cover 205 are drawn out, and then discharged into the environment. At the same time, with the cooperation of the second dustproof mesh 304 and the cylindrical hole 303, the air in the environment can be filtered before entering the above-mentioned space, that is, the flowing air is used to take away the heat dispersed in the above-mentioned space when the data acquisition module 208, the communication module 209, the data analysis and comparison module 210, the power module 211 and the fan 305 are working, so as to ensure that the data acquisition module 208, the communication module 209, the data analysis and comparison module 210, the power module 211 and the fan 305 will not be affected in use due to the failure to discharge the heat from the above-mentioned space in time. When the monitoring personnel need to regularly observe the shell condition of the generator 1, the monitoring personnel can first use With the cooperation of the monitoring equipment, wires, communication module 209, controller 413 and driver 414 in the monitoring room, the two second motors 415 are started at the same time, and the output ends of the two second motors 415 rotate in opposite directions. Then, each of the second motors 415 started will drive the rotating rod 409 connected thereto to rotate with the cooperation of the corresponding set of auxiliary holes 408 and bearings. Then, the two rotating rotating rods 409 will drive the corresponding protective shells 411 to rotate with the cooperation of the hollow blocks 410 connected thereto. At the same time, the two rotating protective shells 411 will also drive the sealing strips 412 connected thereto to move. When the two protective shells 411 have rotated 90 degrees, the controller 413 will pause the two at the same time through the cooperation of the driver 414. The second motor 415 then starts the two multi-stage telescopic rods 404 at the same time. At this time, each of the started multi-stage telescopic rods 404 will drive the corresponding camera 406 to move in cooperation with the mounting seat 402 and the corresponding L-shaped plate 405. When the two cameras 406 are moved to a point where they cannot move, the controller 413 will pause the two multi-stage telescopic rods 404 at the same time, and then control the two cameras 406 to start at the same time. Then, each of the started cameras 406 will shoot its monitored area, and then each camera 406 will transmit the image data of the generator 1 casing captured to the controller 413. At the same time, when each camera 406 completes the shooting operation in the area where it is located, the controller 413 will directly start the first motor 403.At this time, the started first motor 403 will drive the connected mounting base 402 to rotate, and the rotating mounting base 402 will drive the two cameras 406 to change position again with the cooperation of the two multi-stage telescopic rods 404 and the two L-shaped plates 405. When the mounting base 402 rotates 90 degrees, the controller 413 will pause the first motor 403, and the two cameras 406 will also stop moving, and start shooting the monitoring area at their location, and also transmit the image data of the generator 1 casing captured to the controller 413. When the controller 413 receives the image data transmitted by the two cameras 406, the controller 413 will compare each received image data with the image data stored in the controller 413 in advance. When the image data received by the controller 413 are the same as the image data previously stored in the controller 413, it means that the shell of the generator 1 is not damaged or cracked. Otherwise, damage or cracks are found. Then the controller 413 will directly transmit the obtained results to the monitoring equipment in the monitoring room through the communication module 209 and the wire for the monitoring personnel to observe and understand. That is, the monitoring personnel can find the problem in advance and solve it in time, so as to ensure the power generation efficiency of the new energy unit. When the auxiliary mechanism 4 completes the monitoring of the shell of the generator 1, the camera 406 is reset to its original position first, and then the two protective shells 411 are reset to their original positions, that is, the data monitoring and image monitoring are used together to judge the working state of the generator 1, so as to reflect the energy efficiency state of the new energy unit.
