Description

Technical Field

[0001] This utility model belongs to the field of outdoor wind turbine tower technology, and in particular relates to an air intake impurity filtration device for outdoor wind turbine towers. Background Technology

[0002] Outdoor wind turbine towers are giant steel cylindrical structures that support the core components of wind turbine generators (such as blades, nacelles, and generators). They typically reach a height of 80–160 meters (equivalent to 30–50 stories) and a diameter of 3–8 meters. They are assembled in sections using flanges. The towers integrate cables, ladders, platforms, and other facilities to provide stable support for the equipment and isolate it from harsh external environments such as wind, sand, and salt spray. The outer walls are made of hot-dip galvanized or anti-corrosion coating technology (resistant to salt spray corrosion ≥2000 hours). The bottom is tightly connected to the foundation with prestressed anchor bolts to ensure wind resistance (able to withstand gusts of 50 m / s or higher). At the same time, the streamlined design is optimized to reduce wind resistance and noise. The structural strength must meet the fatigue life standard of 20 years (equivalent to 107 cycles of cyclic load). It is a key infrastructure in wind farms that combines mechanical performance and environmental adaptability.

[0003] For example, Chinese patent CN218293753U discloses a wind turbine tower, including a tower body and a tower body reinforcement assembly. The tower body reinforcement assembly includes a load-bearing skeleton that forms an integral load-bearing structure with the tower body, and concrete reinforcement components that increase the thickness of the tower. The load-bearing skeleton includes multiple fastening clamps that are tightly attached to the outside of the tower body, and multiple vertical connecting rods connecting the fastening clamps. The fastening clamps are arranged axially along the tower body, and the vertical connecting rods are arranged circumferentially along the tower body. The concrete reinforcement components are located at the load-bearing skeleton and are tightly connected to the tower body. This invention has advantages such as improving the service life and safety reliability of the tower, and being easy to construct.

[0004] The aforementioned patent has the following problems: In actual use, it does not have the function of filtering impurities at the air inlet of the wind turbine tower, which causes dust in the air to enter the interior of the wind turbine tower, affecting the use of the wind turbine tower and making it difficult for staff to use. We propose an air inlet impurity filtration device for outdoor wind turbine towers. Utility Model Content

[0005] The purpose of this invention is to provide an air intake impurity filtration device for outdoor wind turbine towers to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides an air intake impurity filtration device for outdoor wind turbine towers, comprising:

[0007] The box body has a connecting pipe fixedly connected to one side, the connecting pipe is connected to the box body, a flange is fixedly connected to one side of the connecting pipe, and a first filter screen is fixedly connected to one end of the box body.

[0008] Two chutes, both of which are located inside the housing, and a second filter screen is slidably installed inside each of the two chutes;

[0009] The housing is fixedly connected to the top of the box. A rotating shaft is rotatably mounted on one side of the housing. A connecting plate is fixedly connected to one end of the rotating shaft. A brush is fixedly connected to one side of the connecting plate. The brush is adapted to the first filter screen.

[0010] A rotating assembly is disposed outside the housing and is used to drive the rotating shaft to rotate.

[0011] In this technical solution, the housing can be installed on the air inlet end of the wind turbine tower through the flange and connecting pipe. The first filter screen can perform primary filtration of the air, and the two second filters screens can perform secondary filtration of the air. By opening the hinged housing, the second filters screens can be removed from the inside of the slide groove and then replaced. Through the above structure, the air inlet of the wind turbine tower can be filtered for impurities.

[0012] By starting the motor, the output of the motor drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw drives the threaded sleeve, slider and rack to move back and forth. Since the rack and gear are meshed, the gear, shaft, connecting plate and brush can be driven to rotate back and forth. With the above structure, the first filter screen can be cleaned, avoiding the phenomenon of the first filter screen being blocked and unable to enter the air, thus making it convenient for the staff to use.

[0013] In the above technical solution, further, a door is hinged to one side of the box body, and a handle is fixedly connected to one side of the door, the handle being made of rubber.

[0014] In this technical solution, the second filter screen can be replaced by opening the hinged housing and then removing it from inside the slide.

[0015] In the above technical solution, a support plate is fixedly connected to one side of the housing, a motor is fixedly installed on the top of the support plate, and a reciprocating lead screw is fixedly connected to the output end of the motor, the reciprocating lead screw extending into the interior of the housing.

[0016] In this technical solution, the support plate ensures that the motor will not idle during operation.

[0017] In the above technical solution, the reciprocating lead screw is further provided with a threaded sleeve on its external thread, and a slider is fixedly connected to the top of the threaded sleeve.

[0018] In this technical solution, by starting the motor, the output end of the motor drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw can drive the threaded sleeve, slider and rack to move back and forth.

[0019] In the above technical solution, a through groove is further provided on the top of the housing, and the slider is slidably installed inside the through groove.

[0020] In this technical solution, the threaded sleeve is prevented from rotating when it moves by sliding the slider inside the through groove.

[0021] In the above technical solution, the rotating component further includes a rack, which is fixedly connected to one side of the slider, and a gear is fixedly connected to one end of the rotating shaft, with the gear meshing with the rack.

[0022] In this technical solution, since the rack and gear are meshed together, the reciprocating movement of the rack can drive the gear, shaft, connecting plate and brush to rotate back and forth.

[0023] In the above technical solution, furthermore, the pore size of both second filter screens is smaller than that of the first filter screen.

[0024] In this technical solution, the filter pore size of the second filter screen is smaller than that of the first filter screen, which allows the second filter screen to perform secondary filtration of the air.

[0025] The beneficial effects of this utility model are:

[0026] 1. The housing can be installed on the air inlet of the wind turbine tower through the flange and connecting pipe. The first filter screen can perform primary filtration of the air, and the two second filters screens can perform secondary filtration of the air. By opening the hinged housing, the second filters screens can be removed from the inside of the slide groove and then replaced. With the above structure, the air inlet of the wind turbine tower can be filtered for impurities.

[0027] 2. By starting the motor, the output end of the motor drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw drives the threaded sleeve, slider and rack to move back and forth. Since the rack and gear are meshed, the gear, shaft, connecting plate and brush can be driven to rotate back and forth. Through the above structure, the first filter screen can be cleaned, avoiding the phenomenon of the first filter screen being blocked and unable to enter the air, thus making it convenient for the staff to use.
