Description

Technical Field

[0001] This invention relates to the field of wind power generation technology equipment and facilities, and specifically to a fixing device for transporting wind turbine blades. Background Technology

[0002] Wind power generation is a renewable energy technology that uses wind power to rotate wind turbine blades, and then uses speed increasers to increase the rotation speed, thereby driving a generator to produce electricity. It has advantages such as being clean and pollution-free, renewable, and having relatively low energy costs, making it one of the important means of global energy transition and addressing climate change. A wind power generation system mainly consists of a wind turbine, generator, tower, and control system. Based on the installation location, it can be divided into onshore wind power and offshore wind power, and it is currently widely used in many countries and regions around the world.

[0003] The transportation of wind turbine blades is a crucial part of the entire installation process of a wind power system. Due to their long structure, special vehicles are required for transportation. During transportation, the blades often experience brief resonance with the vehicle body. If this is not addressed promptly, it can lead to damage to the blades or the vehicle itself.

[0004] In summary, a fixing device for transporting wind turbine blades was designed. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings, the present invention provides a fixing device for transporting wind turbine blades.

[0006] The present invention achieves the above objectives through the following technical solutions: A fixing device for transporting wind turbine blades includes a vehicle platform and a wind turbine blade. The vehicle platform and the wind turbine blade are fixedly connected by the fixing device, which includes a front fixing component and a rear fixing component. The rear end of the wind turbine blade is fixed to the rear end of the vehicle platform by the rear fixing component. The front-end fixing assembly includes two mirror-symmetrical semi-U-shaped fixing plates. The front end of the wind turbine blade is located between the two fixing plates, which are located at the front end of the vehicle body. The rear fixing component includes several fixing rings. A buffer rubber ring is provided at the center of the fixing ring. A connecting strip is provided between the fixing ring and the vehicle plate. Several power generation units are evenly arranged on the connecting strip. A fluid composed of dielectric particles and insulating liquid is provided inside the connecting strip. A wire runs through the connecting strip from top to bottom. The wire is exposed and in contact with the fluid. The wire is electrically connected to a power unit. Both the power generation unit and the power unit are electrically connected to a control unit. Vibration sensors are installed at the rear end of the vehicle body and the rear end of the wind turbine blades, and the vibration sensors are electrically connected to the control unit.

[0007] Preferably, the inner wall of the fixing plate is provided with a buffer pad, the transverse cross section of which is W-shaped. The buffer pad can reduce the friction between the front end of the wind turbine blade and the inner wall of the fixing plate, thus protecting the front end of the wind turbine blade.

[0008] Preferably, the inner wall of the fixing plate is provided with several slots at equal intervals, all of which face upwards. A spring is provided at the bottom of the slot, and a buffer block is provided at the top of the spring. The buffer block is located at the bottom of the buffer pad. Since the wind turbine blade is placed from top to bottom between the two fixing plates, the vertically arranged springs can play a buffering role when the front end of the wind turbine blade is placed between the two fixing plates.

[0009] Preferably, the power generation unit includes a fixed ring, a wind turbine, and a generator. The fixed ring is fixed on a fixed belt, and the generator is connected to the wind turbine via a drive. The generator is fixed inside the fixed ring by a fixed rod. All generators are electrically connected to an energy storage unit, which is electrically connected to the control unit and the power supply unit respectively. When the wind turbine rotates, it drives the generator to generate electricity. The generated energy enters the energy storage unit for conversion and storage, so that the power supply unit can call upon the energy. This achieves the goal of eliminating the need for external power supply for the fixed device.

[0010] Preferably, the vehicle panel is also provided with a first damping plate and a second damping plate. The front-end fixing component is fixed to the front end of the vehicle panel through the first damping plate, and the rear-end fixing component is fixed to the rear end of the vehicle panel through the second damping plate. The bottom of the first damping plate and the second damping plate are provided with a number of shock absorbers.

[0011] Preferably, the number of shock absorbers at the bottom of the first and second damping plates is different. Due to the different number of shock absorbers, the vibration coefficients at the front and rear ends of the wind turbine blades are different, thereby reducing the probability of resonance between the wind turbine blades and the vehicle plate.

[0012] Preferably, a slide rail is provided between the fixed plate and the first damping plate. The fixed plate moves on the first damping plate via the slide rail. A pin is provided on the slide rail to fix the fixed plate on the slide rail. The distance between the two fixed plates can be controlled by the slide rail and the pin to accommodate wind turbine blades of different diameters.

[0013] Preferably, the fixing ring is made of plastic, which can reduce the probability of the wind turbine blades being struck by lightning during thunderstorms, thus reducing the likelihood of the power generation unit being damaged.

[0014] Preferably, the connecting strip is equipped with several indicator lights, which are electrically connected to a power module. The control unit is electrically connected to the indicator lights through the power module. In the event of poor visibility, the control unit controls the indicator light switch through the power module, thereby providing a warning to vehicles and people behind. The entire warning function does not require an external power supply.

[0015] Preferably, the connecting strip is hollowed out inside, which can be used to fill fluid.

[0016] The beneficial effects of this invention are: in the wind turbine blade transport fixing device: The wind turbine blades can be fixed by the front-end fixing components and the rear-end fixing components, which meets the requirements of long-distance transportation. The connecting belt is equipped with a power generation unit, which, together with the power supply unit and control unit, enables the fixed device to generate its own power, improving the device's endurance and intelligence. The connecting strip contains a fluid composed of dielectric particles and insulating liquid. It is fluid under normal conditions, solidifies into a near-solid state when the wire is energized, and returns to a flexible state when the power is off. This can be used to change the state of the connecting strip and adjust the force between the wind turbine blade and the vehicle body, reducing the probability of resonance between the wind turbine blade and the vehicle body and improving the reliability of the fixing device.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] like Figures 1-5As shown, a fixing device for transporting wind turbine blades includes a platform 1 and a wind turbine blade 2. The platform 1 and the wind turbine blade 2 are fixedly connected by a fixing device, which includes a front fixing component 3 and a rear fixing component 5. The rear end of the wind turbine blade 2 is fixed to the rear end of the platform 1 by the rear fixing component 5. The front fixing component 3 includes two mirror-symmetrical semi-U-shaped fixing plates 7, with the front end of the wind turbine blade 2 located between the two fixing plates 7, which are located at the front end of the platform 1. The rear fixing component 5 includes several fixing rings 11. A buffer rubber ring 12 is provided at the center of the fixing ring 11. A connecting strip 13 is provided between the fixing ring 11 and the vehicle plate 1. A plurality of power generation units 15 are evenly arranged on the connecting strip 13. The inside of the connecting strip 13 contains a fluid composed of dielectric particles and insulating liquid. A wire runs through the inside of the connecting strip 13 from top to bottom. The wire is exposed and in contact with the fluid. The wire is electrically connected to a power supply unit. Both the power generation unit 15 and the power supply unit are electrically connected to a control unit. Vibration sensors are provided at the rear end of the vehicle plate 1 and the rear end of the wind turbine blade 2. The vibration sensors are electrically connected to the control unit.

[0020] The working principle of the wind turbine blade 2 transport fixing device is as follows: the fixing device is used to fix the wind turbine blade 2 to the vehicle platform 1. First, the distance between the two mirror-symmetrical semi-U-shaped fixing plates 7 of the front fixing component 3 is adjusted according to the diameter of the front end of the wind turbine blade 2 to fix the front end of the wind turbine blade 2. Then, the crane embeds the front end of the wind turbine blade 2 between the two fixing plates 7, and then the fixing rings 11 are put in. The fixing rings 11 can be fixed to the rear end of the wind turbine blade 2 through the buffer rubber rings 12, and at the same time, they can also play an insulating role. Each fixing ring 11 is then connected to the vehicle platform 1 through the connecting belt 13, which can play a certain swing buffering role for the rear end of the wind turbine blade 2.

[0021] During vehicle operation, vibration sensors at the rear ends of vehicle panel 1 and wind turbine blade 2 detect the vibration frequencies between them. When their vibration frequencies are close to or equal, the control unit energizes the wires via the power module. When the wires are energized, they act on the fluid inside the connecting strip 13, which consists of dielectric particles and insulating liquid. Upon energization, the fluid instantly solidifies into a near-solid state, increasing the strength of the connecting strip 13. This alters the force between vehicle panel 1 and wind turbine blade 2, creating a disturbance. Consequently, the vibration frequencies between vehicle panel 1 and wind turbine blade 2 differ. At this point, the control unit de-energizes the wires via the power module, allowing the fluid inside the connecting strip 13 to return to its normal, soft state.

[0022] Specifically, the inner wall of the fixing plate 7 is provided with a buffer pad 8. The transverse cross section of the buffer pad 8 is W-shaped. The buffer pad 8 can reduce the friction between the front end of the wind turbine blade 2 and the inner wall of the fixing plate 7, and play a protective role for the front end of the wind turbine blade 2.

[0023] Specifically, the inner wall of the fixing plate 7 is provided with several slots at equal intervals, all of which face upwards. A spring is provided at the bottom of the slot, and a buffer block is provided at the top of the spring. The buffer block is located at the bottom of the buffer pad 8. Since the wind turbine blade 2 is placed between the two fixing plates 7 from top to bottom, the vertically arranged springs can play a buffering role when the front end of the wind turbine blade 2 is placed between the two fixing plates 7.

[0024] Specifically, the power generation unit 15 includes a fixed ring 18, a wind turbine 17, and a generator. The fixed ring 18 is fixed on a fixed belt. The generator is connected to the wind turbine 17 via a drive. The generator is fixed inside the fixed ring 18 via a fixed rod 16. All generators are electrically connected to an energy storage unit. The energy storage unit is electrically connected to the control unit and the power supply unit, respectively. When the wind turbine 17 rotates, it drives the generator to generate electricity. The generated energy enters the energy storage unit for conversion and storage, so that the power supply unit can call upon the energy. This realizes that the fixed device does not require external power supply.

[0025] Specifically, the vehicle panel 1 is also provided with a first shock absorber 4 and a second shock absorber 6. The front end fixing component 3 is fixed to the front end of the vehicle panel 1 through the first shock absorber 4, and the rear end fixing component 5 is fixed to the rear end of the vehicle panel 1 through the second shock absorber 6. The bottom of the first shock absorber 4 and the second shock absorber 6 are provided with several shock absorbers.

[0026] Specifically, the number of shock absorbers at the bottom of the first damping plate 4 and the second damping plate 6 is different. Due to the different number of shock absorbers, the vibration coefficients of the front and rear ends of the wind turbine blade 2 are different, which can reduce the probability of resonance between the wind turbine blade 2 and the vehicle plate 1.

[0027] Specifically, a slide rail 9 is provided between the fixed plate 7 and the first damping plate 4. The fixed plate 7 moves on the first damping plate 4 via the slide rail 9. A pin 10 is provided on the slide rail 9 to fix the fixed plate 7 on the slide rail 9. The distance between the two fixed plates 7 can be controlled by the slide rail 9 and the pin 10 to accommodate wind turbine blades 2 of different diameters.

[0028] Specifically, the fixing ring 11 is made of plastic, which can reduce the probability of the wind turbine blade 2 being struck by lightning and causing the power generation unit 15 to break down.

[0029] Specifically, the connecting strip 13 is equipped with several indicator lights 14, which are electrically connected to a power module. The control unit is electrically connected to the indicator lights 14 through the power module. When visibility is poor, the control unit controls the indicator lights 14 to switch on and off through the power module, thereby providing a warning to vehicles and people behind. The entire warning function does not require an external power supply.

[0030] Specifically, the connecting strip 13 has a hollow interior, which can be used to fill fluid.

[0031] Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
