Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a vibration detection device for a cabin of an equipment. Background Art

[0002] Wind power generation is achieved through wind turbines that can convert wind mechanical energy into electrical energy. Wind turbines mainly consist of three parts: blades, nacelles, and towers. The gearbox and generator of the wind turbine are all installed in the nacelle. The blades are connected to the generator in the nacelle through the main shaft so that when the blades rotate under the action of wind, they can drive the generator to generate electricity, thereby realizing the conversion of wind mechanical energy into electrical energy. In the process of the wind turbine converting wind mechanical energy into electrical energy, many parts of the wind turbine will vibrate. When this vibration reaches a certain level, it will cause vibration failure, thereby damaging the entire wind turbine. In order to avoid vibration failure, a vibration detection device is usually installed in the nacelle to detect its vibration condition, and corresponding protection measures are taken for the wind turbine based on the detection data.

[0003] In the related prior art, there is a vibration detection device for a wind turbine set with announcement number CN214887495U, which includes: a base, a rotating shaft is provided in the middle of the base, a worm gear is connected to the middle of the rotating shaft, a worm is provided on the left side of the worm gear, an electric motor is connected to the end of the worm gear, a protective shell is connected to the upper end of the rotating shaft, a magnet A is provided in the protective shell, a connecting rod A is connected to the middle of the magnet A, a connecting rod B is provided inside the connecting rod A, a spring is connected to the rear end of the connecting rod A, a pressure sensor is provided on the rear side of the spring, a wireless signal transceiver module is provided below the pressure sensor, and a magnet B is provided below the magnet A; when the wind turbine set vibrates, the magnet A drives the spring to squeeze the pressure sensor, and the value detected by the pressure sensor is sent to an external terminal in real time through the wireless signal transceiver module.

[0004] However, in the above scheme, the device is installed on the base inside the wind turbine by bolts. When the device is repaired or maintained, the device needs to be taken out from the inside of the wind turbine. When taking out the device, the bolts on the base connected to the wind turbine need to be removed one by one to disconnect the base from the wind turbine so that the device can be further taken out. In summary, the process of removing the bolts is relatively cumbersome and inconvenient to carry out maintenance work on the device. Utility Model Content
