Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a tower inclination and settlement monitoring device for a wind turbine generator set. Background Art

[0002] The tower of a wind turbine refers to the structure that supports the wind turbine. It is located between the foundation of the wind turbine and the power generation part of the wind turbine and is used to lift the wind turbine to a height suitable for capturing wind energy. The tower is usually a hollow cylindrical or polygonal structure with sufficient height to allow the blades of the wind turbine to reach higher wind speed areas, thereby improving power generation efficiency. The tower of a wind turbine is usually made of steel, concrete or composite materials and has sufficient strength and stability to support the weight and operating load of the entire wind turbine. The height of the tower can vary depending on the design and installation location of the wind turbine, usually ranging from tens of meters to hundreds of meters.

[0003] Traditional wind turbine tower tilt and settlement monitoring devices usually consist of the following main components: sensor system, data acquisition unit, data processing unit, communication module and power system. The sensor system is responsible for real-time monitoring of the tower tilt angle and settlement, including tilt sensors and settlement sensors. The data acquisition unit is responsible for collecting data transmitted by the sensor and sending it to the data processing unit for processing and analysis. The data processing unit processes the data through algorithms, identifies abnormal conditions and generates corresponding alarm information. The communication module is responsible for transmitting the monitoring data to the monitoring center or operation and maintenance personnel to achieve remote monitoring and management. The power system provides a stable power supply for the monitoring device, usually powered by batteries or solar panels to ensure the continuous operation of the monitoring system.

[0004] The existing wind turbine tower inclination and settlement monitoring device has many defects in the manual monitoring method, such as high investment cost, slow detection speed, easy to have human errors, and cannot effectively detect the settlement of the tower. However, the settlement problem of the wind turbine tower will also bring safety hazards. In order to solve these problems, the monitoring system can be expanded, and automatic monitoring devices such as tilt sensors and settlement sensors can be introduced, and combined with advanced data acquisition, processing and communication technologies, real-time monitoring and remote management of tower inclination and settlement can be realized. For this purpose, a wind turbine tower inclination and settlement monitoring device is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 2 and Figure 4 The utility model provides an embodiment: a wind turbine tower inclination and settlement monitoring device, including a base 6, a second fixed plate 21 is fixedly connected to the side wall of the base 6, a hollow plate 11 is fixedly connected to the output end of the second fixed plate 21, a second hollow plate 22 is fixedly connected to the bottom of the base 6, a damping rod 23 is fixedly connected to the inside of the second hollow plate 22, a connecting plate 20 is fixedly connected to the inner wall of the second hollow plate 22, a sensor 10 is fixedly connected to the top of the connecting plate 20, a telescopic rod 9 is fixedly connected to the top of the connecting plate 20, a first fixed plate 7 is fixedly connected to the top of the base 6, a hydraulic cylinder 8 is fixedly connected to the top of the base 6, and the output rear end of the hydraulic cylinder 8 is fixedly connected to the bottom of the hollow plate 11.

[0033] Specifically, by setting the hydraulic cylinder 8, the effect of stably supporting the hollow disk 11 is achieved. Subsequently, when the base 6 is subjected to force, the damping rod 23 is subjected to pressure and moves downward. This movement causes the telescopic rod 9 to contract, and at the same time the sensor 10 is also subjected to pressure, and starts to record relevant information and transmit the signal. The effect of measuring the settlement is achieved. By detecting the movement of the base 6 and the expansion and contraction of the telescopic rod 9, the settlement of the wind turbine tower can be discovered and recorded in time to ensure the safety and stability of the system.

[0035] Specifically, when the pillar 4 tilts, its tilt will cause pressure on the roller 12. The stressed roller 12 will drive the connecting column 13 to move, and the movement of the connecting column 13 will cause the first fixed column 14 to move. The movement of the first fixed column 14 will also drive the movement of the second fixed column 16. The movement of the first fixed column 14 causes the spring 15 to contract, and at the same time, the movement of the second fixed column 16 causes the sensor ball 18 to move and abut against the opening inside the detector 19, thereby achieving the effect of measuring the tilt. Through the position change of the sensor ball 18 in the hole inside the detector 19, the tilt of the pillar 4 can be accurately monitored, so that necessary measures can be taken in time.

[0037] Specifically, when using the wind turbine tower inclination and settlement monitoring device, first fix the base 6 on the bottom plate. Then, drive the fixed block 3 to rotate through the output end of the first motor 2. The rotation of the fixed block 3 drives the fan blade 1 to rotate, thereby achieving the wind power generation effect and achieving the goal of wind power generation.

[0038] Working principle: When using the wind turbine tower inclination and settlement monitoring device, first fix the base 6 on the bottom plate, then drive the fixed block 3 to rotate through the output end of the first motor 2, and the rotation of the fixed block 3 drives the fan blade 1 to rotate, so as to achieve the effect of wind power generation, and then when the pillar 4 is tilted, the inclination of the pillar 4 causes the roller 12 to be subjected to pressure, and the roller 12 is subjected to force to drive the connecting column 13 to move, and the movement of the connecting column 13 drives the first fixed column 14 to move, and the movement of the first fixed column 14 drives the second fixed column 16 to move, and the movement of the first fixed column 14 causes the spring 15 to contract, and at the same time, the movement of the second fixed column 16 causes the sensor ball 18 to abut against the hole opened inside the detector 19, so as to achieve the effect of measuring the inclination, and then the hollow disk 11 is stably supported by the setting of the hydraulic cylinder 8, and then the force on the base 6 causes the damping rod 23 to be subjected to pressure and move downward, and the movement of the base 6 causes the telescopic rod 9 to contract together, and the sensor 10 receives information while the telescopic rod 9 is extended and retracted, and the signal is transmitted, so as to achieve the effect of measuring the settlement.
