[0019] The present invention provides an air filter element structure for a wind turbine generator set. It has the following beneficial effects:

[0020] (1) The present invention is equipped with a strip plate through a base frame, a tank body, an air intake pipe, a duct, a filter plate, a motor, a disc 1, a frame plate, an activated carbon plate, a disc 2, a long rod, a long tube, a fan plate and a short tube. The frame plate drives the activated carbon plate to rotate forward. The activated carbon plate contacts the air with a large area during the rotation. The activated carbon plate rotates to filter impurities such as dust in the air, and the purified air is discharged from the air outlet of the frame plate. The activated carbon plate separates the dust and gas in the air during the rotation, so that the air does not carry dust into the cabin, and prevents the air from carrying dust into the cabin, which causes the motor body in the cabin to be easily corroded and damaged by dust. The fan plate fans the gas in the tank body to flow upward quickly, so that the air in the tank body does not accumulate in the tank body, and prevents a large amount of air from accumulating in the tank body, which causes the equipment to have a poor air intake effect. At the same time, the strip plate fans the air below the tank body, so that the air does not accumulate below the tank body, and prevents the air from accumulating below the tank body, which causes the air below the tank body to be difficult to discharge.

Under the limitation of friction, the shaking of the disc 2 during rotation is reduced, so that the frame plate on the disc 2 does not shake violently during rotation, and the frame plate on the disc 2 is prevented from shaking violently during rotation, causing the equipment to run unsmoothly. In addition, the double arc plate drives the chamfer plate to rotate forward. During the forward rotation of the chamfer plate, the chamfer of the chamfer plate scrapes off impurities on the wall surface of the tank body, so that the wall surface of the tank body remains clean, and a large amount of impurities attached to the wall surface of the tank body are prevented, which may cause the rubber roller to be easily corroded and damaged by impurities.

[0022] (3) The present invention sets a dehumidification device so that the straight ring block, the inclined plate, the mesh cylinder, the calcium chloride column, the round rod, the ring block and the arc-shaped spring piece cooperate with the sliding plate, and the mesh cylinder drives the calcium chloride column to rotate forward. During the forward rotation of the calcium chloride column, the calcium chloride column contacts the purified air, and the calcium chloride column absorbs moisture in the air to prevent the motor body from being easily affected by moisture due to high moisture content in the air. Moreover, under the elastic force of the arc-shaped spring piece, the sliding plate rests on the top of the mesh cylinder, reducing the shaking of the mesh cylinder during rotation, and preventing the mesh cylinder from shaking violently during rotation and causing the calcium chloride column in the mesh cylinder to be damaged.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figures 1-8 One embodiment of the present invention is: an air filter element structure for a wind turbine generator set, comprising a nacelle 1, a motor body 2 fixedly mounted on the bottom end of the nacelle 1, a heat dissipation module 3 fixedly mounted on the top surface of the motor body 2, and a pipe of the heat dissipation module 3 fixedly connected to the top end of the nacelle 1;

[0034] A filter assembly 31 is provided at the top of the interior of the cabin 1. The filter assembly 31 includes a base frame 301, which is fixed to the bottom end of the interior of the cabin 1. The base frame 301 is located on the right side of the motor body 2. A tank body 302 is fixedly installed on the top surface of the base frame 301. Three air intake pipes 303 are passed through and fixed to the bottom right side of the tank body 302. One end of the three air intake pipes 303 away from the tank body 302 passes through and is fixedly connected to the left side of the inner wall of the cabin 1. A conduit 304 is passed through and fixed to the top left side of the tank body 302. The conduit 304 is away from the tank body. One end of 302 is fixedly connected to the right side of the heat dissipation module 3, a filter disc 305 is fixedly installed on the top of the inner wall of the tank body 302, a motor 306 is fixedly installed on the bottom end of the chassis 301, the shaft of the motor 306 passes through and is rotatably installed on the top end of the chassis 301, the shaft of the motor 306 passes through and is rotatably installed on the middle of the bottom surface of the tank body 302, a disc 307 is fixed on the top surface of the shaft of the motor 306, the bottom surface of the disc 307 is rotatably connected to the bottom end of the tank body 302, and the top surface of the disc 307 is fixed. Four frame plates 308, the outer walls of the four frame plates 308 are provided with a plurality of air outlet holes, the inner walls of the four frame plates 308 are respectively fixed with four activated carbon plates 309, the top surfaces of the four frame plates 308 are fixed with disc 2 310, the top surface of disc 2 310 is rotatably connected to the bottom surface of the filter disc 305, the top surface of the filter disc 305 is provided with four arc-shaped notches, the inner walls of the four arc-shaped notches of the filter disc 305 are respectively fixed with four filter screens, the rotating shaft of the motor 306 drives the disc 1 307 to rotate forward, and the disc 1 307 drives the frame plate 308 to rotate forward. The frame plate 308 drives the activated carbon plate 309 to rotate forward. The activated carbon plate 309 contacts the air over a large area during the rotation process. The activated carbon plate 309 rotates to filter out impurities such as dust in the air. The purified air is discharged from the air outlet of the frame plate 308. The activated carbon plate 309 separates the dust and gas in the air during the rotation process, so that the air does not carry dust into the cabin 1. This prevents the air filter element structure from carrying dust into the cabin 1 when it is in use, causing the motor body 2 in the cabin 1 to be easily corroded and damaged by the dust.

[0035] The top surface of the disc 1 307 is provided with a fan assembly 32, and the fan assembly 32 includes four long rods 321, which are fixed to the top surface of the disc 1 307. The top surfaces of the four long rods 321 are fixedly connected to the bottom surface of the disc 2 310. Four long tubes 322 are respectively fixed in the middle of the outer walls of the four long rods 321, and fan plates 323 are respectively fixed to the outer walls of the four long tubes 322. When the fan plates 323 rotate forward, the fan plates 323 fan the gas in the tank body 302 to flow upward quickly, so that the air in the tank body 302 will not accumulate in the tank body 302, thereby avoiding the air filter element from being blocked. When the structure is in use, a large amount of air accumulates in the tank body 302, resulting in poor air intake effect of the equipment. The fan assembly 32 also includes four short tubes 324, and the four short tubes 324 are respectively fixed to the bottom of the outer wall of the four long rods 321. The outer walls of the four short tubes 324 are respectively fixed with four strip plates 325. When the strip plates 325 are in the process of forward rotation, the strip plates 325 fan the air under the tank body 302, so that the air will not accumulate under the tank body 302, thereby avoiding the accumulation of air under the tank body 302 when the air filter structure is in use, making it difficult to discharge the air under the tank body 302.

[0036] During use, the operator starts the motor body 2 in the cabin 1, and the motor body 2 supports the heat dissipation module 3. The motor body 2 generates a large amount of heat during use, and the heat dissipation module 3 dissipates the heat for the motor body 2. Since the air filter element structure is in the process of purifying the air, the dust in the air is easy to enter the cabin 1. At this time, the base frame 301 supports the tank body 302, and the operator starts the motor 306 on the base frame 301. The shaft of the motor 306 starts to rotate forward. The shaft of the motor 306 drives the disc 1 307 to rotate forward, and the disc 1 307 drives the frame plate 308 to rotate forward, and the frame plate 308 drives the activated carbon plate 309 to rotate forward, and the frame plate 308 drives the disc 2 310 to rotate forward, and the disc 2 310 rotates below the filter disc 305. At the same time, the air enters the air inlet pipe 303, and the air inlet pipe 303 delivers the air into the tank body 302. , the activated carbon plate 309 comes into contact with the air over a large area during the rotation process, and the activated carbon plate 309 rotates to filter impurities such as floating dust in the air, and the purified air is discharged from the air outlet of the frame plate 308. At the same time, the purified air passes through the filter screen of the filter disc 305, and the purified air enters the top of the tank body 302, and the purified air enters the duct 304. The duct 304 transports the purified air to the heat dissipation module 3, and the heat dissipation module 3 cools the motor body 2, so that the activated carbon plate 309 separates the floating dust and gas in the air during the rotation process, so that the air does not carry floating dust into the cabin 1, preventing the air from carrying floating dust into the cabin 1 when the equipment is in use, thereby avoiding the problem that the motor body 2 in the cabin 1 is easily corroded and damaged by floating dust when the air filter element structure is in use.

[0037] When the rotating shaft of the motor 306 drives the disc 1 307 to rotate forward, the disc 1 307 drives the long rod 321 to rotate forward, the long rod 321 drives the long tube 322 to rotate forward, and the long tube 322 drives the fan plate 323 to rotate forward. During the forward rotation of the fan plate 323, the fan plate 323 fans the gas in the tank body 302 to flow upward rapidly, so that the air in the tank body 302 will not accumulate in the tank body 302, thereby preventing a large amount of air from accumulating in the tank body 302 when the equipment is in use, thereby avoiding the air filter structure from accumulating in the tank body 302 when the air filter is in use. To solve the problem of poor air intake effect of the equipment, while the disc 307 drives the long rod 321 to rotate forward, the long rod 321 drives the short tube 324 to rotate forward, and the short tube 324 drives the strip plate 325 to rotate forward. During the process of forward rotation, the strip plate 325 fans the air under the tank body 302, so that the air will not accumulate under the tank body 302, preventing the air from accumulating under the tank body 302 when the equipment is in use, thereby avoiding the problem that the air filter structure accumulates under the tank body 302 when it is in use, making it difficult to discharge the air under the tank body 302.

[0038] See also Figures 1-8 On the basis of the above embodiment, another embodiment of the present invention further includes an anti-shake device 4 and a dehumidification device 5, wherein the anti-shake device 4 is provided in the middle of the top surface of the second disc 310, and the anti-shake device 4 includes a shaft disc 41, a horizontal plate 42, two U-shaped frames 43 and two rubber rollers 44. The shaft disc 41 is fixed in the middle of the top surface of the second disc 310, and the bottom end of the shaft disc 41 penetrates and is rotatably connected to the top surface of the filter disc 305. The top surface of the shaft disc 41 is rotatably connected to the inner top of the tank body 302. The horizontal plate 42 is fixed to the bottom of the outer wall of the shaft disc 41, and the two U-shaped frames 43 are fixed to the horizontal plate 42. At both ends of the outer wall, two rubber rollers 44 are rotatably mounted on the inner walls of the two U-shaped frames 43 respectively. The horizontal plate 42 is located above the filter disc 305. The outer walls of the two rubber rollers 44 are in rolling contact with the inner wall of the tank body 302. The rubber rollers 44 roll on the wall surface of the tank body 302. Under the limitation of friction, the vibration of the second disc 310 during rotation is reduced, so that the frame plate 308 on the second disc 310 will not vibrate violently during rotation, thereby avoiding the frame plate 308 on the second disc 310 vibrating violently during rotation when the air filter element structure is in use, causing the equipment to run unsmoothly.

[0039] The anti-shake device 4 also includes two short rods 45, two double-arc plates 46 and two chamfered plates 47. The two short rods 45 are fixed on the outer wall of the horizontal plate 42, and the two double-arc plates 46 are respectively fixed on the ends of the two short rods 45 away from the horizontal plate 42. The two chamfered plates 47 are respectively fixed on the outer walls of the two double-arc plates 46. The chamfers of the two chamfered plates 47 are in sliding contact with the inner wall of the tank body 302. The double-arc plates 46 drive the chamfered plates 47 to rotate forward. During the forward rotation of the chamfered plates 47, the chamfers of the chamfered plates 47 scrape off impurities on the wall of the tank body 302, so that the wall of the tank body 302 remains clean, avoiding the situation where a large amount of impurities adhere to the wall of the tank body 302 when the air filter structure is in use, causing the rubber roller 44 to be easily corroded and damaged by impurities.

[0040] A dehumidification device 5 is provided on the outer wall of the anti-shake device 4. The dehumidification device 5 includes two straight ring blocks 51, an inclined plate 52, two mesh cylinders 53 and two calcium chloride columns 54. The two straight ring blocks 51 are respectively fixed on the outer walls of the two short rods 45, the inclined plate 52 is fixed on the top surfaces of the two straight ring blocks 51, the two mesh cylinders 53 are respectively fixedly installed on both sides of the top surfaces of the inclined plates 52, and the two calcium chloride columns 54 are respectively fixedly installed on the inner bottom ends of the two mesh cylinders 53. The inclined plate 52 is sleeved on the bottom of the outer wall of the shaft disc 41, and the mesh cylinder 53 drives the calcium chloride columns 54 to rotate forward. During the forward rotation process, the calcium chloride columns 54 come into contact with the purified air. The calcium chloride columns 54 absorb moisture in the air to avoid the air filter structure from containing high moisture when the air contains high moisture, causing the motor body 2 to be easily affected by moisture.

[0041] The dehumidification device 5 also includes two round rods 55, two ring blocks 56, two arc-shaped spring pieces 57 and two sliding holes 58. The two round rods 55 are respectively fixed on the top surface of the inclined plate 52, and the two round rods 55 are respectively located on the side where the two mesh cylinders 53 are close to each other. The two ring blocks 56 are respectively fixed on the outer walls of the two round rods 55, and the two arc-shaped spring pieces 57 are respectively fixed on the outer walls of the two ring blocks 56. The two sliding holes 58 are respectively slidably installed on the top of the outer walls of the two round rods 55. One end of the two arc-shaped spring pieces 57 away from the two ring blocks 56 is fixedly connected to the bottom surfaces of the two sliding holes 58. The two sliding holes 58 are respectively located on the top surfaces of the two mesh cylinders 53. Under the elastic force of the arc-shaped spring pieces 57, the sliding holes 58 are pressed against the top of the mesh cylinder 53, reducing the shaking of the mesh cylinder 53 during rotation, and avoiding the air filter structure from shaking and damaging the calcium chloride column 54 in the mesh cylinder 53 when the mesh cylinder 53 is rotated.

[0042] While the frame plate 308 drives the second disc 310 to rotate forward, the second disc 310 drives the shaft disc 41 to rotate forward, the shaft disc 41 drives the cross plate 42 to rotate forward, the cross plate 42 drives the U-shaped frame 43 to rotate forward, and the U-shaped frame 43 drives the rubber roller 44 to rotate forward. The rubber roller 44 rolls on the wall surface of the tank body 302. Under the limitation of friction, the vibration of the second disc 310 during rotation is reduced, so that the frame plate 308 on the second disc 310 does not vibrate violently during rotation, thereby preventing the frame plate 308 on the second disc 310 from vibrating violently during rotation when the equipment is in use, thereby avoiding the problem of the frame plate 308 on the second disc 310 vibrating violently during rotation when the air filter structure is in use, causing the equipment to run unsmoothly.

[0043] While the shaft disc 41 drives the cross plate 42 to rotate forward, the cross plate 42 drives the short rod 45 to rotate forward, the short rod 45 drives the double arc plate 46 to rotate forward, and the double arc plate 46 drives the chamfer plate 47 to rotate forward. During the forward rotation of the chamfer plate 47, the chamfer of the chamfer plate 47 scrapes off impurities on the wall of the tank body 302, keeping the wall of the tank body 302 clean, preventing a large amount of impurities from adhering to the wall of the tank body 302 when the equipment is in use, thereby avoiding the problem that a large amount of impurities are attached to the wall of the tank body 302 when the air filter element structure is in use, causing the rubber roller 44 to be easily corroded and damaged by impurities.

[0044] While the horizontal plate 42 drives the short rod 45 to rotate forward, the short rod 45 drives the straight ring block 51 to rotate forward, the straight ring block 51 drives the inclined plate 52 to rotate forward, the inclined plate 52 drives the mesh cylinder 53, and the mesh cylinder 53 drives the calcium chloride column 54 to rotate forward. During the forward rotation, the calcium chloride column 54 comes into contact with the purified air and absorbs moisture in the air to prevent the air from containing high moisture when the equipment is in use, thereby avoiding the problem that the motor body 2 is easily affected by moisture when the air filter element structure is in use and the air contains high moisture.

[0045] When the straight ring block 51 drives the inclined plate 52 to rotate forward, the inclined plate 52 drives the round rod 55 to rotate forward, the round rod 55 drives the ring block 56 to rotate forward, the ring block 56 drives the arc-shaped spring piece 57 to rotate forward, and the arc-shaped spring piece 57 drives the sliding plate 58 to rotate forward. Under the elastic force of the arc-shaped spring piece 57, the sliding plate 58 rests on the top of the mesh cylinder 53, reducing the shaking of the mesh cylinder 53 during rotation, preventing the mesh cylinder 53 from shaking violently when the equipment is in use, thereby avoiding the problem of the calcium chloride column 54 in the mesh cylinder 53 being shaken and damaged due to the violent shaking of the mesh cylinder 53 during rotation of the air filter structure when in use.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
