Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a spraying equipment for offshore wind turbines. Background Technology

[0002] Wind power generation is an important technology in the field of clean energy, especially offshore wind turbines. Due to the special nature of the marine environment, offshore wind turbines face severe corrosion and erosion problems. Applying protective coatings to the surface of offshore wind turbines has become a routine maintenance task. The coating equipment sprays paint onto the surface of the offshore wind turbine to protect it. However, before spraying the paint, manual cleaning of the offshore wind turbine is required. In the marine environment, the cleaning process before spraying the coating takes a long time. Often, just after cleaning, corrosive dust floating in the air will adhere to the cleaned surface of the offshore wind turbine. Spraying paint on a surface with corrosive dust reduces the adhesion of the paint to the offshore wind turbine, and the corrosive dust inside the coating corrodes the offshore wind turbine. The paint sprayed on the outside of the offshore wind turbine does not provide comprehensive protection for the unit, causing corrosion damage and reducing the service life of the offshore wind turbine.

[0021] like Figures 1-6 As shown.

[0022] A spraying device for offshore wind turbines includes a main unit 1, a spraying rod 2, and a connecting pipe 3. The main unit includes a dust collection device 4, a protective layer spraying device 5, and an anti-oxidation spraying device 6. The dust collection device 4 is activated to clean the surface of the offshore wind turbine, removing any debris to prevent re-contamination. The protective layer spraying device 5 applies a protective coating to the cleaned surface, effectively protecting the turbine's surface from damage. To combat the corrosion of the marine environment, the anti-oxidation spraying device 6 applies an anti-oxidation coating to the protective coating layer on the offshore wind turbine, effectively improving the oxidation resistance of the protective coating. This provides the offshore wind turbine with dual protection against corrosion from the protective coating and against oxidation from the anti-oxidation coating, extending its service life in harsh environments. The spraying rod 2 consists of a handle 20 and a spray / suction head 21. The spray / suction head 21 is connected to one end of the handle 20. By manipulating the handle 20, the spray / suction head 21 is positioned to perform the spraying operation. The connecting pipes 3 consist of a dust suction pipe 30, a protective layer spraying pipe 31, and an anti-oxidation spraying pipe 32. The dust suction pipe 30, the protective layer spraying pipe 31, and the anti-oxidation spraying pipe 32 are respectively connected to the dust suction device 4, the protective layer spraying device 5, and the anti-oxidation spraying device 6. The main unit 1 is connected to the handle 20 via the connecting pipes 3. The handle 20 is movably connected to the spray / vacuum head 21. The dust suction device 4 in the main unit 1 is connected to the handle 20 via the dust suction pipe 30. The handle 20 is connected to the spray / vacuum head 21 to suck up clean debris. The protective layer spraying device 5 in the main unit 1 is connected to the handle 20 through the protective layer spraying pipe 31, and then connected to the spray / vacuum head 21 through the handle 20 to perform protective layer spraying on the clean surface of the offshore wind turbine. The anti-oxidation spraying device 6 in the main unit 1 is connected to the handle 20 through the anti-oxidation spraying pipe 32, and then connected to the spray / vacuum head 21 through the handle 20 to spray anti-oxidation coating on the protective layer coating surface sprayed on the offshore wind turbine.

[0023] Preferably, the handle 20 includes a handheld part 201 and a start handle 202. The handheld part 201 is provided with a pin part 203, which includes a pin hole 204. A pin 205 is connected to the pin hole 204. The start handle 202 is rotatably connected to the pin part 203 via the pin 205. The side of the start handle 202 facing the handheld part 201 includes a vacuum cleaner start button 206, a protective coating start button 207, and an anti-oxidation coating start button 208. Pressing the start handle 202 activates the vacuum cleaner start button 206 and the protective coating start button 208. Applying pressure to the device start button 207 and the anti-oxidation spraying device start button 208 respectively turns on the switches. The dust collection device start button 206 is an electronically controlled button; pressing the dust collection device start button 206 via the start handle 202 connects the internal circuit and powers on the dust collection device 4, activating its operation. The protective layer spraying device start button 207 and the anti-oxidation spraying device start button 208 are mechanical valve connection switches; pressing these buttons via the start handle 202 activates the protective layer spraying device 5 and the anti-oxidation spraying device. When the internal pressure of device 6 decreases, its internal pressure sensor switch opens, energizing the protective coating spraying device 5 and the anti-oxidation spraying device 6. Releasing the start handle 202 disconnects the channels of the protective coating spraying device 5 and the anti-oxidation spraying device 6, causing the internal pressure to rise. Once the pressure sensor switch detects that the set pressure value has been reached, it disconnects the power, stopping the protective coating spraying device 5 and the anti-oxidation spraying device 6 from operating. Completely releasing the start handle 202 resets the vacuum cleaner start button 206, the protective coating device start button 207, and the anti-oxidation device start button 208. When the power is disconnected, the dust collection device 4, the protective layer spraying device 5, and the anti-oxidation spraying device 6 stop working. The start buttons 206, 207, and 208 of the dust collection device, protective layer spraying device, and anti-oxidation spraying device are respectively arranged on the handheld part 201.

The motor 2105 and the pivot shaft 2107 are connected. 02 The motor gear 2106 is connected to the rotating shaft gear 2104 via a transmission. By pressing the start button 206 of the dust collection device through the start handle 202, the internal circuit is connected and the motor 2105 on the spray / vacuum head 21 is started. The motor 2105 drives the motor gear 2106, which drives the rotating shaft gear 2104 connected to it. The rotating shaft gear 2104 drives the rotating shaft 2102 to drive the cleaning brush 2103 to rotate. The rotating cleaning brush 2103 cleans the surface of the offshore wind turbine and sucks away the cleaned debris through the dust suction hole 2107 connected to the dust suction pipe 30, making the surface of the offshore wind turbine clean and dust-free, which is conducive to the smooth progress of the next spraying work.

The protective coating spraying device 5 inside the main unit 1 is connected to the protective coating device 5. By pressing the start button 207 of the protective coating device through the start handle 202, the pressure inside the protective coating spraying device 5 drops, and the pressure sensing switch is energized to start the protective coating spraying device 5. The protective coating spraying device 5 delivers the protective coating paint to the protective coating distributor 2110 through the protective coating spraying pipe 31. The protective coating distributor 2110 distributes the paint to the protective coating sprayers 2111. The paint is sprayed from the protective coating sprayers 2111 and applied to the clean surface of the offshore wind turbine, so that the offshore wind turbine is protected by the anti-corrosion coating and has a longer service life.

[0026] Preferably, the spray / vacuum head 21 further includes an antioxidant diverter 2120 and at least one antioxidant sprayer 2121. The antioxidant diverter 2120 has a hollow structure and is positioned parallel to one side of the protective layer diverter, and is fixedly connected to the outer shell 2100.

Connect the anti-oxidation spraying device 6 inside the main unit 1. Press the start button 208 of the anti-oxidation device through the start handle 202 to reduce the pressure inside the anti-oxidation spraying device 6. The pressure sensing switch is energized to start the anti-oxidation spraying device 6.
