Problems solved by technology

[0003] Traditional monitoring of bolt looseness is generally carried out by manual on-site inspections. The inspection cycle is generally half a year or even a year. The loosening of bolts cannot be found in time, and it is difficult to accurately locate the position of loose bolts. Manual inspections are more labor-intensive and material resources
In the prior art, some bolt loosening monitoring devices carry out online monitoring by installi

Abstract

The invention relates to a bolt loosening monitoring device which comprises a device body, a clamping mechanism, a sensing assembly and a wireless transmitter. The clamping mechanism comprises two clamping plates which are oppositely arranged, the clamping plates are movably arranged on the device body, a clamping opening for clamping a flange is formed between the two clamping plates, and hole grooves for a bolt to penetrate in are formed in the opposite inner side walls of the two clamping plates. The sensing assembly is arranged in at least one hole groove and used for detecting whether thebolt is displaced or not, and the wireless transmitter is arranged on the device body, electrically connected with the sensing assembly and used for transmitting the serial number of the bolt. Basedon the structure, the clamping mechanism can clamp the flange through the self clamping force, the bolt loosening monitoring device can be easily disassembled and assembled through the self clamping force without any tool, and the installation efficiency of the bolt loosening monitoring device is greatly improved; and in addition, the bolt loosening monitoring device also has the functions of remotely monitoring the bolt loosening condition on line, accurately positioning the position of the loosened bolt and the like.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a bolt loosening monitoring device. Background technique [0002] With the popularization and application of new energy power generation technology, wind power generation has become one of the most important directions in the field of power generation. The construction of wind power generating units is in full swing, and its power generation share is also increasing year by year. Due to the need to withstand various wind loads, the components of the wind turbine, especially the towers of each section, are connected by flanges and high-strength bolts. In the actual operation process, the components of the wind turbine, especially the tower, are prone to vibration under huge alternating loads, which are finally transmitted to the flanges and bolts, causing the bolts to loosen or even break, causing serious accidents. Therefore, the staff usually needs to m...
