Description

Technical Field

[0001] The invention relates to the technical field of wind turbine blade deicing equipment, and in particular to a high-pressure atomizing jet deicing device for wind turbine blades covered with ice. Background Art

[0002] As a clean, pollution-free and sustainable new energy form, wind power generation is of great significance to alleviating the current dependence on conventional energy and the environmental pollution problems it brings. However, in low temperature and high humidity environments, wind turbine blades often have various problems caused by ice. The existing deicing methods are mainly: 1) Mechanical deicing: that is, to break the ice by mechanical methods and then blow it away by airflow; 2) Heating deicing: using various thermal energies to heat objects, and heating the electrical components and metal components on the surface of the fuselage to quickly de-ice the surface; 3) Coating deicing: by coating anti-icing coating on the surface of the substrate, the adhesion of ice to the substrate surface and the amount of ice on the surface are reduced, and then the ice is easier to detach from the substrate surface under the action of wind and gravity; 4) Solvent deicing: Solution deicing usually involves spraying ice-melting liquid on the frozen surface to gradually melt the ice layer.

[0003] Through the analysis of the above existing situation, two problems can be found: First, the physical methods of mechanical deicing and heating deicing currently used cause great damage to the blades themselves; the chemical deicing methods of coating deicing and solvent deicing require the use of coating coating and solvent spraying. Second, most of the current deicing methods require manual operation on the blades.

[0060] The embodiment of the present invention provides a high-pressure atomizing jet deicing device for wind turbine blades covered with ice, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The high-pressure atomizing jet deicing device for wind turbine blades covered with ice includes a shell, which is supported by a frame 1 located inside the shell, and includes a power supply 4, an air compressor 2, an air path component, a liquid storage device 5 and a liquid path component. The power supply 4 is fixed to the frame 1 through a pressure plate. The air compressor 2 is arranged on the frame 1 and connected to the power supply 4. The air path component is located inside the shell, and one end is connected to the air compressor 2, and the other end is connected to the ejection component 3. The liquid storage device 5 is arranged on the frame 1. The liquid path component is located inside the shell, and one end is connected to the liquid storage device 5, and the other end is connected to the ejection component 3. Among them, the high-pressure gas compressed by the air compressor 2 passes through the air path component, and then mixes with the liquid in the liquid storage device 5 in the ejection component 3 after passing through the liquid path component, and is ejected outward from the ejection component 3.

[0061] In this embodiment, after turning on the power supply 4, the air compressor 2 and the liquid storage device 5 start to operate, the high-pressure gas compressed by the air compressor 2 enters the ejection assembly 3 after passing through the air path assembly, and the liquid ice-melting agent is stored in the liquid storage device 5. The liquid in the liquid storage device 5 passes through the liquid path assembly and is mixed with the high-pressure gas in the ejection assembly 3, and then is ejected from the ejection assembly 3 to the target ice layer on the surface of the blade, breaking the ice layer and flowing into the cracks on the ice surface, so that the ice layer is separated from the blade. Thus, it can avoid the damage to the blade itself by physical deicing in the prior art and the need to use paint coating and solvent spraying when deicing by chemical methods, and it can also avoid the need for manual climbing to the blade to operate during the deicing process.

[0062] In a specific embodiment, in combination Figure 1 , Figure 2 , Figure 3 and Figure 5 The air path assembly includes an air filter device 23, a first two-position two-way solenoid valve 25, an electric proportional valve 22, an air heater 21 and a first pressure gauge 24. The air filter device 23 is connected to the inlet of the air compression device 2. The first two-position two-way solenoid valve 25 is connected to the air compression device 2 through a pipeline. The electric proportional valve 22 is connected to the first two-position two-way solenoid valve 25 through a pipeline. One end of the air heater 21 is connected to the electric proportional valve 22 through a pipeline, and the other end is connected to the ejection assembly 3. The first pressure gauge 24 is arranged on the pipeline between the electric proportional valve 22 and the air heater 21.

[0063] In this embodiment, the air filter device 23 filters the outside air, and the filtered gas enters the air compressor 2. The high-pressure gas compressed by the air compressor 2 passes through the first two-position two-way solenoid valve 25, the electrical proportional valve 22, and the air heater 21 in the pipeline in sequence, and then enters the ejection assembly 3. Thus, a path for the high-pressure gas is formed. After the high-pressure gas is mixed with the liquid in the ejection assembly 3, it is ejected to the target ice layer on the surface of the blade, breaking the ice layer and flowing into the cracks on the ice surface, so that the ice layer is separated from the blade.

[0064] Exemplarily, the first pressure gauge 24 monitors the gas pressure in the pipeline between the electric proportional valve 22 and the air heater 21 .

[0065] Exemplarily, the connection between the pipeline and the air compression device 2, the air filtering device 23, the first two-position two-way solenoid valve 25, the electric proportional valve 22, the air heater 21 and the first pressure gauge 24 is connected by connecting parts in the prior art. The connecting parts include but are not limited to joints, bolts, elbows, etc.

[0066] In a specific embodiment, in combination Figure 1 , Figure 2 and Figure 3 The air path assembly further includes a three-way connector 26. The two ends of the three-way connector 26 are simultaneously connected to the pipeline between the electric proportional valve 22 and the air heater 21, and the other end is connected to the first pressure gauge 24.

[0067] In this embodiment, one joint of the three-way joint 26 is connected to the pipe at one end of the electric proportional valve 22 , the other joint is connected to the pipe at one end of the air heater 21 , and the other joint of the three-way joint 26 is connected to the first pressure gauge 24 .

[0068] Exemplarily, the three-way connector 26 is a ferrule-type internally threaded three-way connector 26 .

[0069] In a specific embodiment, in combination Figure 1 , Figure 2 , Figure 3 and Figure 5 The air filter device 23 is also provided with a pressure reducing valve 27 and an oil mist collector 28. The pressure reducing valve 27 is provided on a pipe inside the air filter device 23 and is used to reduce the pressure of the filtered gas. The oil mist collector 28 is provided inside the air filter device 23 and adds lubricant to the pressure reducing valve 27 and the components of the air filter device 23.

[0070] In this embodiment, the pressure reducing valve 27 and the lubricator 28 are both arranged in the air filtering device 23 .

[0071] The pressure reducing valve 27 reduces the pressure of the filtered gas, and the oil mist collector 28 adds lubricant to the components of the pressure reducing valve 27 and the air filter device 23. Thus, the air filter device 23 improves the filtration purity of the air, and further strengthens the high-pressure gas after mixing with the liquid in the ejection assembly 3 and being ejected to the target ice layer on the blade surface.

[0072] In a specific embodiment, in combination Figure 1 , Figure 2 , Figure 3 and Figure 5 , the liquid path component includes a boost valve 51, a second two-position two-way solenoid valve 52, a speed regulating valve 53, a third two-position two-way solenoid valve 54, a pilot relief valve 55 and a second pressure gauge 56. The boost valve 51 is arranged on a pipeline connected to the liquid outlet of the liquid storage device 5, and boosts the liquid flowing out of the liquid storage device 5. The second two-position two-way solenoid valve 52 is connected to the boost valve 51 through a pipeline. The speed regulating valve 53 is connected to the second two-position two-way solenoid valve 52 through a pipeline. The third two-position two-way solenoid valve 54 is simultaneously connected to the pipelines on both sides of the speed regulating valve 53 through a pipeline, and is connected to the ejection component 3. The pilot relief valve 55 is connected to the liquid return port of the liquid storage device 5 through a pipeline. The second pressure gauge 56 is connected to the pilot relief valve 55 through a pipeline.

[0073] In this embodiment, the liquid ice-melting agent in the liquid storage device 5 passes through the boost valve 51, the second two-position two-way solenoid valve 52, the speed control valve 53, and the third two-position two-way solenoid valve 54 in sequence, and then enters the ejection component 3. After being mixed with the high-pressure gas in the ejection component 3, it is ejected outward from the ejection component 3 to the target ice layer on the surface of the blade, breaking the ice layer and flowing into the cracks in the ice surface, thereby separating the ice layer from the blade.

[0074] Exemplarily, the pilot-operated relief valve 55 adjusts the relief pressure in the liquid storage device 5 .

[0075] Exemplarily, the connection between the pipeline and the liquid storage device 5, the boost valve 51, the second two-position two-way solenoid valve 52, the speed regulating valve 53, the third two-position two-way solenoid valve 54, the pilot relief valve 55 and the second pressure gauge 56 is connected by connecting parts in the prior art. The connecting parts include but are not limited to joints, bolts, elbows, etc.

[0076] In a specific embodiment, in combination Figure 1 , Figure 2 , Figure 3 and Figure 5 The liquid path assembly also includes a connecting pipe, one end of which is connected to the pipe between the pilot relief valve 55 and the second pressure gauge 56 , and the other end of which is connected to the pipe between the boost valve 51 and the second two-position two-way solenoid valve 52 .

[0077] In this embodiment, one end of the connecting pipe is connected to the pipe between the boost valve 51 and the second two-position two-way solenoid valve 52, and the other end is connected to the pipe between the pilot overflow valve 55 and the second pressure gauge 56, forming a liquid return pipeline. The second pressure gauge 56 detects the liquid pressure in the connecting pipe.

[0078] Exemplarily, the second two-position two-way solenoid valve 52 is a normally closed two-position two-way solenoid directional control valve, and the third two-position two-way solenoid valve 54 is a normally open two-position two-way solenoid directional control valve.

[0079] In a specific embodiment, Figure 5 As shown, the liquid path component further includes a straight ball valve 59. The straight ball valve 59 is arranged on a pipeline connected to the liquid discharge port 58 of the liquid storage device 5.

[0080] In this embodiment, the ice-melting agent remaining in the liquid storage device 5 is discharged from the liquid discharge port 58 of the liquid storage device 5 under the control of the through ball valve 59 .

[0081] In a specific embodiment, Figure 5 As shown, the liquid storage device 5 further includes a liquid adding port 57. The liquid adding port 57 is disposed at the top of the liquid storage device 5 and is used to add liquid into the liquid storage device 5.

[0082] In this embodiment, when the interior of the liquid storage device 5 is empty, liquid ice-melting agent is added into the liquid storage device 5 from the liquid adding port 57 by a feeding gun of a feeding vehicle.

[0083] In a specific embodiment, Figure 4 As shown, the ejector assembly 3 includes an ejector body, a first nozzle 31, a suction chamber 32, a mixing chamber 33, a diffusion chamber 34 and a second nozzle 35. The ejector body is connected to the shell. The first nozzle 31 is arranged in the ejector body and is connected to the air heater 21 and the third two-position two-way solenoid valve 54 through a pipeline. The suction chamber 32 is arranged in the ejector body and is connected to the end of the first nozzle 31 away from the air heater 21 side. The mixing chamber 33 is arranged in the ejector body and is connected to the end of the suction chamber 32 away from the first nozzle 31 side. The diffusion chamber 34 is arranged in the ejector body and is connected to the end of the mixing chamber 33 away from the suction chamber 32 side. The second nozzle 35 is arranged outside the ejector body and is connected to the end of the diffusion chamber 34 away from the mixing chamber 33 side.

[0084] In this embodiment, high-pressure gas and liquid pass through the suction chamber 32, the mixing chamber 33, the diffusion chamber 34 and the second nozzle 35 in sequence in the first nozzle 31 located inside the ejector, and are then sprayed outward to the target ice layer on the blade surface, breaking the ice layer and flowing into the cracks in the ice surface, thereby separating the ice layer from the blade.

[0085] In the present invention, the deicing device is placed at the target deicing position by an unmanned aerial vehicle, an air compressor is used to provide an air source, and a high-speed gas is used to inject an ice-melting agent. A high-temperature and high-pressure ice-melting agent atomized flow is formed through the action of the first nozzle 31, the suction chamber 32, the mixing chamber 33, the diffusion chamber 34 and the second nozzle 35, and is discharged at a pressure higher than the atmospheric pressure to act on the ice-covered surface of the blade. The high temperature of the atomized flow and the ice-melting agent are used together to make the ice on the blade surface unstable and produce cracks.

[0086] The sprayed high-pressure ice-melting liquid atomized flow enters the cracks in the ice surface and delivers the ice-melting agent to the joint surface of the ice cover and the blade. The ice layer at the joint surface melts under the action of the ice-melting liquid, loosening the attachment between the ice layer and the blade surface and forming a cavity at the joint surface.

[0087] The high-temperature and high-pressure ice-melting agent atomized flow continues to be input into the cavity to increase the pressure in the cavity to form a high-pressure cavity. At the same time, under the action of the ice-melting agent, the adhesion between the ice layer and the blade at the joint surface is reduced, and the ice layer is separated by high pressure, thereby achieving rapid and large-scale separation of the ice layer.

[0088] Exemplarily, the de-icing device is integrated into one piece, which is convenient for carrying and installation, and its pipeline is also shorter, further reducing the pressure loss.

[0089] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
