Problems solved by technology
The existing wind power generation device fixes the blades or other components at a high place through the tower pole. During daily maintenance or overhaul, workers need to take the elevator box hoisted by the steel wire rope to reach the corresponding position for related operations. The long service time of the steel wire rope causes wear and tear. Strands greatly reduce the strength of the steel wire rope, which is prone to accidental construction accidents, so it is urgent to design a sensor for detecting broken strands of the steel wire rope

Embodiment
[0015] figure 1 It is a structural schematic diagram of a sensor for detecting broken strands of a steel wire rope according to the present invention, figure 2 It is a structural schematic diagram of the sound detection mechanism of the present invention. As shown in the figure, a sensor for detecting broken strands of a steel wire rope includes a fixed plate 1, a fixed tube 3, a brush tube 2, a sound detection mechanism 4 and a sound processing module 5. The sound processing module 5 of this embodiment is a filtering module, which is used to filter out disturbing noises. The filtering module belongs to the prior art, so the specific circuit structure will not be described here. The sound processing module 5 is connected with the sound detection mechanism 4, the sound detection mechanism 4 is fixed on the inner wall of the fixed pipe 3, the sound detection mechanism 4 includes a fixed shell 44, a diaphragm 41, a substrate 42, a power supply 46, a resistor 43 and an output sig...

The invention discloses a sensor for detecting strand breakage of a steel wire rope. The sensor comprises a fixing plate, a fixing pipe, a brush pipe, a sound detection mechanism and a sound processing module, the sound processing module is connected with the sound detection mechanism, the sound detection mechanism is fixed to the inner wall of the fixing pipe, the brush pipe is fixed in the fixing pipe, and the steel wire rope penetrates through the brush pipe. The sensor for detecting the stand breakage of the steel wire rope is used for detecting whether the broken strand of the steel wire rope exists or not, early warning is conducted in advance, and casualties caused by sudden breakage of the steel wire rope are avoided.
Description
technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor for detecting broken strands of steel wire ropes. Background technique [0002] Wind power generation is to convert the kinetic energy of wind into electric energy. As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW. Among them, land The upper wind energy reserves are about 253 million kW, and the offshore wind energy reserves that can be developed and utilized are about 750 million kW, totaling 1 billion kW. At the end of 2003, the national installed capacity of electric power was about 567 million kW. The existing wind power generation device fixes the blades or other components at a high place through the tower pole. During daily maintenance or overhaul, workers need to take the ele...
