[0003] The high maintenance quality of high-strength bolts of wind turbines is the guarantee for the long-term safe and stable operation of the units. In terms of conventional unit bolt torque maintenance work, it is mainly the main engine manufacturer or the owner's operation and maintenance personnel who use the common wind turbine maintenance hydraulic torque wrench on the market to tighten the bolts with the designed torque. This tool is a purely mechanical structure, consisting of a hydraulic pump station and a torque wrench. When working, it is necessary to manually adjust the pressure to set the torque value. However, due to the uneven skill levels of on-site maintenance personnel, there are blind spots in the narrow space on site, and it is impossible to ensure that the torque is in place, which is prone to over-torque and under-torque. In view of this, we propose an intelligent torsion bar. Utility Model Content

Due to the uneven skill levels of on-site maintenance personnel, there are blind spots in the narrow space on site, and it is impossible to ensure that the torque is in place, which easily leads to technical problems of over-torque and under-torque.

It solves the problem that the existing hydraulic torque wrench needs to manually adjust the pressure to set the torque value when working. Due to the uneven skill levels of on-site maintenance personnel, there are blind spots in monitoring in the narrow space on site, and it is impossible to ensure whether the torque is in place, which is prone to problems of over-torque and under-torque.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the utility model relates to an intelligent torsion bar, including a rod body component 2 with an active end 1 detachably fixedly provided on the top, the active end 1 includes a quick-release shell 101 with a Bluetooth module 104 connected to an external terminal fixedly provided inside, and a data acquisition module 102 is also fixedly provided inside the quick-release shell 101, the rod body component 2 includes a rod body 201 with a driven end 205 fixedly provided at the bottom end, a stress detection sensor for detecting torque during operation and an angle detection element for detecting torsion angle during operation are fixedly provided inside the driven end 205, the stress detection sensor and the angle detection element are both electrically connected to the data acquisition module 102, and a power line laying channel 206 is centrally provided inside the rod body 201.

[0025] The hydraulic oil and pressure are supplied to the torsion bar by the hydraulic pump station. The hydraulic pump station outlet pressure monitoring universal plug-in and automatic pressure regulating plug-in device support Bluetooth Internet of Things function, which can realize rapid installation and removal on the hydraulic station without affecting the original equipment. It is convenient to store and does not require additional purchase of hydraulic station equipment, reducing the upgrade cost. An external terminal can also be set. The external terminal is a mobile phone with a built-in APP. The APP has built-in torque and design values ​​of various specifications of the fan bolts. The APP can realize the mutual proofreading and judgment of the torque value detected by the torsion bar and the hydraulic pump station outlet pressure monitoring plug-in, and adjust the preset pressure of the corresponding model bolt according to the built-in data through the automatic pressure regulating plug-in, which can maximize the accuracy of the torque value.

[0026] The mobile phone APP has built-in design torque values ​​for bolts of various types of corresponding units, and establishes independent numbers for flange bolts on each layer. After selecting the corresponding bolt on the mobile phone, the hydraulic pump station outlet pressure monitoring can be activated, and the pressure adjustment algorithm between pressure value and torque value can be used to dynamically adjust the pressure value through the automatic pressure adjustment plug-in to achieve the torque output value corresponding to the torque bar. However, in order to ensure the absolute accuracy of the torque output value of the torque bar, the torque value data of the driven end of the torque bar is fed back to the APP in real time for data processing, and compared with the theoretical output torque of the pressure monitoring value. If there is an inconsistency, the APP will issue an alarm and it is necessary to immediately check whether it is a torque wrench failure, a stress sensor failure, or a pump station pressure failure, so as to avoid insufficient torque or excessive torque; during the torque process, the angle sensor built into the torque bar quick-release shell will immediately send back the bolt rotation angle after each torque is applied, and record it in the corresponding bolt ledger. The APP works via Bluetooth connection and can be used offline. The data is stored locally on the terminal and supports export functions for maintenance and analysis.

[0027] like Figure 2 As shown, in the embodiment of the present utility model, a battery 103 and a battery 2 105 are fixedly disposed inside the quick-release housing 101 for electrically connecting the data acquisition module 102, the stress detection sensor and the angle detection element and providing them with electrical energy.

[0029] Working principle: This embodiment provides an intelligent torsion bar. When in use, the Bluetooth module 104 is connected to the external terminal. When the hydraulic torque wrench is used, the hydraulic oil pushes the torsion bar to move, thereby causing the driven end 205 to move. The torque of the driven end 205 is detected during operation by the stress detection sensor. By setting an angle detection element, the torsion angle of the driven end 205 is detected during operation by the stress detection sensor, and the detection data is transmitted to the data acquisition module 102. The detection data is sent to the external terminal through the Bluetooth module 104. Intelligent control is performed through the external terminal, thereby realizing automatic pressure adjustment of the pressure oil, ensuring the uniformity of bolt torque tightening, and improving the bolt tightening effect.
