Technical Field

[0001] The present invention relates to the technical field of thermal power machinery maintenance equipment, and in particular to a thermal power machinery maintenance device. Background Art

[0002] Thermal power machinery is a key set of equipment for energy conversion and power generation in thermal power plants. Its core task is to efficiently convert the chemical energy of fossil fuels such as coal, oil, and natural gas into electrical energy. The system mainly consists of a boiler, a steam turbine, a generator, and multiple auxiliary systems, forming a complete energy conversion chain from fuel combustion to generate steam, to the steam driving the steam turbine to rotate, and finally the generator converting mechanical energy into electrical energy. In addition, systems such as fuel processing, water treatment, flue gas purification, and electrical control operate in coordination to ensure the safe and efficient operation of the power plant. The technical performance and operating efficiency of thermal power machinery are directly related to the stability and economy of power supply; in the maintenance process, vibration monitoring and spectrum analysis technologies are particularly important. They can capture abnormal vibration signals of components such as bearings and gears, such as amplitude changes and frequency offsets, providing a basis for fault warning. When a fault occurs, the maintenance device can quickly locate the fault point, such as bearing damage or unbalanced vibration, facilitating precise repair. However, current detection technologies face challenges, especially on the surface of non-magnetic machinery, where the problem of fixing the detection equipment significantly reduces the monitoring accuracy and operational convenience, and innovative solutions are urgently needed. In response to the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution.

The plurality of adjustment buttons are respectively installed on the detection and analysis main body, the liquid crystal display screen is installed on the detection and analysis main body, and a probe combination locking structure is installed on the detection and analysis main body. The probe combination locking structure includes: a data and power transmission line, a vibration frequency sensor, an extended fitting block, a vibration amplification cavity, and a fitting vibration membrane; The data and power transmission line is installed on the detection and analysis main body, the vibration frequency sensor is installed on the data and power transmission line, and the vibration frequency sensor is inserted into the extended fitting block. The extended fitting block is provided with the vibration amplification cavity, the vibration amplification cavity is connected to the vibration frequency sensor, the fitting vibration membrane is installed on the vibration amplification cavity, a pair of transient electromagnetic combination structures are installed on the extended fitting block, and a pair of combined clamping displacement structures are installed on the extended fitting block; It should be noted that in the above, when starting the detection and analysis main body, the parameters to be detected can be adjusted through multiple adjustment buttons and the liquid crystal display screen. The extended fitting block is attached to the surface of the thermal power machinery. When the thermal power machinery is running, the vibration is conducted to the vibration amplification cavity through the fitting diaphragm, and after being amplified, it is received by the vibration frequency sensor, and then transmitted to the detection and analysis main body through the data power transmission line, and the current operating state of the thermal power machinery is displayed through the liquid crystal display screen.

If fitting and fixing are required, the vibration frequency sensor is inserted into the expansion fitting block. The first dynamic electromagnet generates a magnetic force to push the first magnet in the first cavity to slide, so that the transmission push rod and the sliding limit block cooperate with the transverse push locking block on it to be inserted into the groove outside the vibration frequency sensor. Then, the second dynamic electromagnet loses the attraction to the second magnet, so that the special-shaped locking block cooperates with the guiding limit block in the guiding chute on the block, and under the action of gravity, it falls to the bottom of the second cavity.

Then drive the first dynamic electromagnet to reverse the current direction and generate a magnetic force to attract the first magnet, so as to drive the transmission push rod and make it slide in the first cavity, and make the sliding limit block, the transverse push locking block and the vibration frequency sensor separate. At this time, the vibration frequency sensor can be easily pulled out from it.

[0021] According to the attached Figures 1-9It is concluded that by activating the detection and analysis main body 1, the parameters to be detected can be adjusted through multiple adjustment buttons 3 and the liquid crystal display screen 2. The extended fitting block 6 is attached to the surface of the thermal power machinery. The vibration during the operation of the thermal power machinery is transmitted to the vibration amplification cavity 7 through the fitting diaphragm 8, amplified, and then received by the vibration frequency sensor 5. After that, it is transmitted to the detection and analysis main body 1 through the data power transmission line 4, and the current operating state of the thermal power machinery is displayed through the liquid crystal display screen 2. The battery pack set in the detection and analysis main body 1 can provide power for the whole process, and the type-c charging port set on the detection and analysis main body 1 can charge the battery pack. The protective buffer sponge set on the fitting diaphragm 8 can prevent scratching when the extended fitting block 6 is attached to the surface of the thermal power machinery, thereby protecting the extended fitting block 6.

Then, the second power electromagnet 12 loses the attraction to the second magnet 14, so that the special-shaped locking block 18 cooperates with the guiding limit block 20 in the guiding chute 19 on the block, and under the action of gravity, it drops to the bottom of the second cavity 10. At this time, the sliding limit block 16 will be blocked by the special-shaped locking block 18, so that the horizontal push locking block 15 is firmly inserted on the surface of the vibration frequency sensor 5.

At this time, the special-shaped locking block 18 will be limited and slide relying on the guiding limit block 20 in the guiding chute 19 on the block. Then, drive the first power electromagnet 11 to reverse the current direction and generate a magnetic force to attract the first magnet 13, thereby driving the transmission push rod 17 and making it slide in the first cavity 9, and separating the sliding limit block 16, the horizontal push locking block 15 from the vibration frequency sensor 5.

After that, drive the combined clamping and displacement structure, so that a pair of anti-slip sensing layers 32 on the corresponding pair of fitting push blocks 31 are in close fit with the surface of the thermal power machinery.
