Description

Technical Field

[0001] The invention relates to the technical field of wind turbine generators, and in particular to a deicing device for a wind turbine generator. Background Art

[0002] As a clean energy, wind power generation plays an increasingly important role in the global energy structure. However, in cold regions or in winter, wind turbine blades are prone to ice formation, which poses a serious challenge to the efficiency and safety of wind power generation.

[0003] Blade icing increases the weight and air resistance of the blades, reducing the output power of the wind turbine. At the same time, uneven icing may cause blade imbalance, cause vibration and noise, and may even damage the blades and other parts of the wind turbine. In addition, icing will also affect the aerodynamic performance of the blades, change the lift and drag coefficients of the blades, and further reduce the efficiency of the wind turbine.

[0004] At present, the commonly used de-icing methods for wind turbines mainly include heating de-icing, mechanical de-icing and chemical de-icing. Heating de-icing usually uses resistance heating or hot air heating, but this method has high energy consumption, and uneven heating may cause local overheating of the blades. Mechanical de-icing requires the use of special equipment to scrape or knock the blades, which can easily cause damage to the blades.

[0021] The beneficial effects of the present invention are as follows:

[0022] In the present invention,

[0023] Innovative de-icing method:

[0024] The present invention adopts the method of crushing deicing and vibrating deicing, combined with a heating component and an ice melting component, and can effectively remove the ice layer on the blades of the wind turbine. This innovative deicing method improves deicing efficiency, reduces deicing time, and reduces deicing costs.

[0025] The design of multiple de-icing components, including a carrier tube, patches, connecting rods, telescopic springs and cone heads, can perform all-round de-icing on the blades to ensure that the ice on the blade surface is completely removed.

[0026] Protect the blades:

[0027] The material selection of the de-icing components has been carefully considered. The copper alloy bearing tube and connecting rod have good thermal conductivity and strength, which can quickly transfer heat and withstand the pressure during de-icing. The thermal conductive rubber patch is soft and has good thermal conductivity, which can fit tightly with the blade surface. The ceramic cone head has high hardness and can effectively scrape the hard ice layer. At the same time, the smooth surface reduces the friction with the blade and reduces the risk of scratching the blade.

[0028] The arc-shaped groove design on the blades allows crushed ice and ice water to fall smoothly from the blades, avoiding additional pressure and damage to the blades caused by ice accumulation.

[0029] Improve de-icing effect:

[0030] The driving motor and rotating rod in the heating component can drive the electric heating wire to rotate, so that the heat is evenly distributed on the ice-melting component, improving the heating effect. At the same time, the setting of the vibration mechanism can make the machine body shake, further promoting the shedding of broken ice and floating snow, and improving the overall de-icing effect.

[0031] The design of the vibration spring allows different quantities to be selected according to the weight of the machine body, achieving stable vibration and fast and stable reset to ensure the smooth progress of the de-icing process.

[0032] Enhanced device stability:

[0033] The setting of the limit assembly can stably position the fixing plate after the vibration mechanism completes operation, preventing the machine body from shaking when not in operation. The cooperation of the insertion rod and the limit block forms multiple cross-shaped fixing parts, which improves the stability and safety of the device.

[0034] The carrying box, bottom plate and storage box in the carrying assembly can effectively carry and protect various components of the device, and the provision of the positioning holes facilitates the installation and fixation of the device.

[0035] Environmental protection and energy saving:

[0036] The deicing device of the present invention adopts a physical deicing method, does not use chemical reagents, and avoids environmental pollution. At the same time, reasonable design and material selection enable the device to efficiently use energy during the deicing process, reduce energy consumption, and meet the requirements of environmental protection and energy saving.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The present invention provides Figure 1-10 A deicing device for a wind turbine generator is shown, comprising a body 1, on which three blades 2 are mounted, each of which is provided with a deicing mechanism, and a vibration mechanism is provided at the bottom of the body 1;

[0050] The three deicing mechanisms all include a heating component and a plurality of ice-melting components, and the plurality of ice-melting components are all arranged on the heating component;

[0051] Multiple ice-melting components all include a carrying tube 3, a patch 9, a connecting rod 12, a telescopic spring 13 and three cone heads 11. The telescopic spring 13 is arranged in the carrying tube 3, and the connecting rod 12 is arranged above the telescopic spring 13. One end of the telescopic spring 13 is detachably connected to the carrying tube 3, and the other end of the telescopic spring 13 is detachably connected to one end of the connecting rod 12. The connecting rod 12 can slide in the carrying tube 3, the patch 9 is detachably connected to the top of the connecting rod 12, and the three cone heads 11 are evenly distributed on the patch 9, and the three cone heads 11 are all detachably connected to the patch 9.

[0052] With the assistance of the telescopic spring piece 13, the connecting rod 12 can be telescopic in the carrying tube 3, thereby realizing the telescopic movement of the patch 9. The resetting force is applied to the connecting rod 12 by the telescopic spring piece 13, and the patch 9 will apply force to the blade 2 for contact. At the same time, according to the different positions of the blade 2, the patch 9 will be telescopic and deformed to contact the blade 2. The patch 9 and the cone head 11 are the parts that are in direct contact with the blade 2. After the cone head 11 is heat-conducted, it can process large hard blocks of ice and realize the decomposition of the ice. The patch 9 can be in contact with the blade 2 over a large area, and the blade 2 can be heated and ice-melted. Through the design of multiple cone heads 11, a large range of ice breaking of the blade 11 can be realized. The joint operation of multiple cone heads 11 is sufficient to decompose the large ice blocks integrally formed on the blade. The design of multiple patches 9 can heat and melt the blade 2 over a large range, and the entire blade 2 can be heated.

[0053] The bearing tube 3 and the connecting rod 12 are both made of copper alloy, the patch 9 is made of heat-conducting rubber, and the three cone heads 11 are all made of ceramic.

[0054] The copper alloy support tube 3 and connecting rod 12 have excellent thermal conductivity, can quickly transfer the heat generated by the heating wire to other components, and have the characteristics of high strength and good wear resistance. The patch 9 has both the flexibility of rubber and good thermal conductivity, can fully contact the surface of the blade 2 to ensure uniform heat transfer, has wear resistance and corrosion resistance, and has a long service life. The cone head 11 has high hardness and can effectively scrape off hard and large pieces of ice on the blade. It is corrosion-resistant, wear-resistant, and has a long service life. The surface is smooth, and when in contact with the blade, the friction is small, which avoids damage to the blade surface due to friction. In summary, the above ice-melting components are made of specific materials according to usage, which brings convenience to users.

[0055] The heating assembly includes a driving motor 8, a heating wire 10 and a rotating rod 15. One end of the rotating rod 15 is detachably connected to the output end of the driving motor 8. The heating wire 10 is wound around the rotating rod 15. The heating wire 10 and the rotating rod 15 are detachably connected.

[0056] The rotating rod 15 carries the heating wire 10, is wound around the rotating rod 15, and is stably connected to the rotating rod 15 over a large area. The driving motor 8 can drive the rotating rod 15 to rotate. The heating wire 10 can heat the ice-melting component thereon, and cooperate with the rotation of the rotating rod 15 to achieve the ice-melting effect.

[0057] The plurality of carrying tubes 3 are evenly distributed on the heating wire 10 , and the plurality of carrying tubes 3 are detachably connected to the heating wire 10 .

[0058] The three blades 2 are all provided with slots 14 , and the three slots 14 are all arc-shaped.

[0059] When the de-icing mechanism completes melting the ice, the crushed ice and ice water will fall efficiently from the groove 14 due to the design of the arc-shaped groove 14, and there will be no accumulation of crushed ice, thereby improving the efficiency of de-icing and bringing convenience to the user.

[0060] The three deicing mechanisms are respectively arranged in the three blades 2 , the three driving motors 8 are respectively detachably connected to the three blades 2 , and the multiple patches 9 are respectively in contact with the three blades 2 .

The multiple slots 20 are evenly distributed on the fixed plate 19, and the rubber ring 6 is set on the fixed plate 19.

[0063] During the operation of the de-icing mechanism or after the de-icing is completed, the user can use the vibration characteristics of the vibration motor 21 to drive the fixed plate 19 to shake. Through the expansion and contraction characteristics of the vibration spring 25, the fixed plate 19 will shake. As the fixed plate 19 shakes, the body 1 will shake as a whole, and the crushed ice and floating snow on it will fall off the body 1, which can effectively deal with the crushed ice and floating snow on the body 1. The above vibration is not a large-scale tilt, but is only shaken by the vibration spring 25 in conjunction with the vibration motor 21. The user can choose different numbers of vibration springs 25 according to the weight of the body to achieve stable vibration and rapid and stable reset after the vibration is completed. Through the setting of the rubber sheet 6, when the body 1 shakes, it will undergo corresponding deformation due to its flexibility, which will not affect the shaking. At the same time, the carrier box 4 is sealed to avoid the entry of debris, which brings convenience to the user.

[0064] Both limit assemblies include a connecting plate 16, an electric push rod 24, a plurality of plug rods 17 and a plurality of limit blocks 18. The connecting plate 16 is detachably connected to the movable end of the electric push rod 24. The plurality of limit blocks 18 are evenly distributed on the plug rod 17.

The plurality of plug rods 17 are all detachably connected to the connecting plate 16.

[0065] When the shaking assembly completes the operation, the electric push rod 24 can push the insertion rod 17 forward until the insertion rod 17 and the limit block 18 enter the corresponding slot 20. The insertion rod 17 and the limit block 18 can form a plurality of cross-shaped fixing parts, thereby achieving stable positioning of the fixing plate 19, which brings convenience to the user.

The device gives priority to using the electric energy generated by the wind turbine itself. When the wind turbine is operating normally, part of the electric energy it outputs is used to meet the needs of the power grid, and the other part is transmitted to the controller and various electrical components of the de-icing device through a dedicated cable. This power supply method can not only make full use of the remaining electric energy of the wind turbine and reduce energy consumption, but also ensure that the de-icing device can be started at any time when the wind turbine is running to remove the ice on the blades in time.
