Description

Technical Field

[0001] This utility model relates to the technical field of wind power generation, and in particular to a wind turbine rotor hoisting cable system. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current (AC). A wind turbine typically consists of components such as a rotor, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. The working principle of a wind turbine is relatively simple: the rotor rotates under the influence of wind, converting the kinetic energy of the wind into the mechanical energy of the rotor shaft. The generator, driven by the rotor shaft, rotates to generate electricity. Broadly speaking, wind energy is also solar energy, so a wind turbine can be described as a thermal energy generator that uses the sun as a heat source and the atmosphere as a working medium. Installing a wind turbine rotor requires the use of lifting equipment. However, wind turbine blades are typically nearly 100 meters long, and the operating environment involves high wind speeds, making lifting and installation quite challenging.

[0003] Conventional hoisting methods typically involve attaching a traction protection device to the tip or root of the blade and then tying a rope for ground personnel to pull and adjust it. This method is difficult to manage safety risks and manual adjustment is not precise enough, often failing to adjust the position of the wind turbine impeller in a timely and accurate manner, thus affecting hoisting efficiency. Utility Model Content

[0004] To address the issues of high safety risk management difficulty and insufficient precision in manual adjustments in existing hoisting methods, which often fail to adjust the position of the wind turbine impeller in a timely and accurate manner, thus affecting hoisting efficiency, this utility model provides a wind turbine impeller hoisting cable system.

[0005] This utility model provides a wind turbine rotor hoisting cable system, which adopts the following technical solution:

[0006] A wind turbine rotor hoisting cable system includes a crane, on one side of which a wind turbine blade is hoisted. A monitoring sensor is installed at the end of the wind turbine blade away from the crane. A guy rope is connected to the side of the wind turbine blade near the monitoring sensor. A guy rope controller is provided at the end of the guy rope away from the wind turbine blade. A control terminal is provided on the side of the guy rope controller away from the wind turbine blade.

[0007] By adopting the above technical solution, monitoring sensors are first installed on the tips of the wind turbine blades. One end of the guy rope is connected to the wind turbine blade, and the other end is connected to the guy rope controller. The wind turbine blade is then lifted using a crane. During the lifting process, the monitoring sensors monitor the position and status of the wind turbine blade in real time and wirelessly transmit the signal to the control terminal. Based on the displayed data, the operator can input commands to the outside of the wind turbine blade through the buttons on the wind turbine blade to generate control commands, which are then sent to the guy rope controller. The guy rope controller controls the guy rope to adjust the status of the wind turbine blade in real time to ensure the smooth lifting process.

[0008] Optionally, the monitoring sensors include a height sensor, an acceleration sensor, and an angular velocity sensor, used to monitor the height, speed, and acceleration status of the wind turbine blades in real time.

[0009] By adopting the above technical solution, it is possible to obtain the height, acceleration, and angle signals of the wind turbine blades in a timely manner.

[0010] Optionally, the guy rope controller is equipped with a tension sensor to monitor the tension transmitted from the guy rope in real time.

[0011] By adopting the above technical solution, it is possible to monitor the tension signal transmitted from the guy rope connected to the guy rope controller in real time.

[0012] Optionally, the control terminal receives monitoring data transmitted from the height sensor, acceleration sensor, angular velocity sensor, and tension sensor in real time. The output terminal of the control terminal is electrically connected to the input terminal of the guy rope controller, and the output terminal of the guy rope controller is electrically connected to the input terminals of the height sensor, acceleration sensor, angular velocity sensor, and tension sensor, respectively.

[0013] By adopting the above technical solution, the monitoring data can be summarized and analyzed, and the real-time status of the wind turbine blades can be calculated, thereby facilitating the real-time adjustment of the wind turbine blade status and ensuring the smooth installation of the wind turbine blades.

[0014] Optionally, the guy rope is made of polyethylene elastomer material, the thickness of the guy rope is 20-30mm, and the tensile strength of the guy rope is not less than 1000kg / cm2.

[0015] By adopting the above technical solutions, the guy ropes have high tensile strength and elastic modulus, and can withstand large tensile forces without easily breaking, thus ensuring the safety and reliability of the guy ropes during use.

[0016] Optionally, the guy rope is detachably connected to the wind turbine blades via a protective sleeve.

[0017] By adopting the above technical solution, the guy rope and the blade are connected by a protective sleeve. When in use, the protective sleeve is directly put on the wind turbine blade, which is convenient for disassembly. Furthermore, the connection between the protective sleeve and the wind turbine blade can increase the contact area and disperse the contact pressure, thus providing better protection for the blade.

[0018] In summary, this utility model has at least one of the following beneficial effects:

[0019] The position and status of the wind turbine blades are monitored in real time by sensors during the hoisting process. The monitoring data is wirelessly transmitted to the control terminal and displayed, which is convenient for operators to check during the cable operation. At the same time, the cable controller controls the cable ropes to adjust the status of the wind turbine blades in real time to ensure the smooth hoisting. Attached Figure Description

The monitoring sensor 1 includes a height sensor, an acceleration sensor, and an angular velocity sensor, used to monitor the height, velocity, and acceleration status of the wind turbine blade 5 in real time. This allows for timely acquisition of the height, acceleration, and angle signals of the wind turbine blade 5.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1A guy rope 2 is connected to the side of the wind turbine blade 5 closest to the monitoring sensor 1. The guy rope 2 is made of polyethylene elastomer material, with a thickness of 20-30mm and a tensile strength of not less than 1000kg / cm2. This gives the guy rope 2 high tensile strength and elastic modulus, enabling it to withstand large tensile forces without easily breaking, thus ensuring the safety and reliability of the guy rope 2 during use.

[0027] Please refer to the attached diagram in the instruction manual. Figure 1 The guy rope 2 is detachably connected to the wind turbine blade 5 via a protective sleeve. The protective sleeve connects the guy rope to the blade, and during use, the protective sleeve is simply placed on the wind turbine blade 5 for easy removal. Furthermore, the connection between the protective sleeve and the wind turbine blade 5 increases the contact area, disperses contact pressure, and provides better protection for the blade.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 A guy rope controller 3 is installed at the end of the guy rope 2 away from the wind turbine blades 5. A tension sensor is installed on the guy rope controller 3 to monitor the tension transmitted from the guy rope 2 in real time. This allows for real-time monitoring of the tension signal transmitted from the guy rope 2 connected to the guy rope controller 3.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 A control terminal 4 is installed on the side of the guy rope controller 3 furthest from the wind turbine blades 5. The control terminal 4 receives real-time monitoring data from the height sensor, acceleration sensor, angular velocity sensor, and tension sensor. The output of the control terminal 4 is electrically connected to the input of the guy rope controller 3, and the output of the guy rope controller 3 is electrically connected to the inputs of the height sensor, acceleration sensor, angular velocity sensor, and tension sensor, respectively. This allows for the summarization and analysis of the monitoring data, and the calculation of the real-time status of the wind turbine blades 5, thereby facilitating real-time adjustments to the status of the wind turbine blades 5 and ensuring the smooth hoisting of the wind turbine blades 5.

[0030] Working principle: In use, the monitoring sensor 1 is first installed on the tip of the wind turbine blade 5. One end of the guy rope 2 is connected to the wind turbine blade 5, and the other end of the guy rope 2 is connected to the guy rope controller 3. The wind turbine blade 5 is lifted by the crane 6. During the lifting process, the height, acceleration and angle signals of the wind turbine blade 5 can be obtained in real time through the height sensor, acceleration sensor and angular velocity sensor on the monitoring sensor 1. At the same time, the tension signal transmitted from the guy rope 2 is obtained in real time through the tension sensor on the guy rope controller 3, and the collected signals are wirelessly transmitted to the control terminal 4. The operator can input commands to the outside of the wind turbine blade 5 through the button on the wind turbine blade 5 according to the displayed data to generate control commands, and send the control commands to the guy rope controller 3.
