Description

Technical Field

[0001] This application relates to the field of generators, and more particularly to a coupled generator. Background Technology

[0002] The basic principle of coupled power generation is to generate electricity using the electromagnetic induction phenomenon produced by the interaction of electric and magnetic fields. Therefore, coupled power generation can be applied to wind power, hydropower, and gas-fired power generation. A coupled power generator typically consists of two components: a rotor and a stator. The rotor is a ring-shaped device, usually composed of conductors and an iron core, while the stator is an iron core with coils. By rotating the rotor, the magnetic flux is changed, generating an electromotive force (EMF); in a coupled power generator, the rotor and stator are coupled together. When the rotor rotates at a certain speed, it generates an alternating magnetic field, which penetrates the coils on the stator, thus producing an EMF.

[0003] Currently, Chinese utility model patent CN221862605U discloses a coupled generator, including a housing assembly, an end cover assembly, and a movable component. The housing assembly includes a casing and a first filter screen, with an opening in the casing. The first filter screen is located at the rear end of the casing. The end cover assembly is located at the opening in the casing and includes a cover plate, a second shaft hole, and a second filter screen. The second shaft hole is located in the center of the cover plate, and the second filter screen is located on the cover plate. The movable component is located inside the casing and includes a rotating shaft, a rotor, a chuck, and fan blades. When the rotating shaft rotates, the fan blades on the shaft rotate with the shaft, driving the airflow to circulate rapidly and blowing out the heat generated by the generator during power generation, thus dissipating heat from the generator and preventing it from being damaged by heat.

[0004] The rotation of the fan blades causes air to flow around the generator, which also allows dust carried in the air to enter the generator. The dust will adhere to the filter screen, and the accumulation of dust over a long period of time will prevent air circulation inside the generator, leading to heat buildup inside the generator and a reduction in the generator's lifespan. Utility Model Content

[0005] In order to reduce dust accumulation inside the generator, improve air circulation, reduce heat buildup, and extend the generator's service life, this application provides a coupled generator.

[0006] This application provides a coupled generator, which adopts the following technical solution: A coupled generator includes a housing, a stator, a rotor, fan blades, and a filter screen. One end of the housing is open, and the other end has a through hole. The stator is disposed within the housing, and the rotor is rotatably connected to the housing. The fan blades are disposed on the rotor. The filter screen is disposed at the opening of the housing and includes a cleaning assembly. The cleaning assembly includes a cleaning frame, a brush, and a driving component. The cleaning frame is rotatably connected to the housing, the brush is disposed on the cleaning frame and abuts against the filter screen, and the driving component drives the cleaning frame to rotate.

[0007] By adopting the above technical solution, when the generator is working, the rotor rotates relative to the stator, and the generator is in the power generation state. The rotor drives the fan blades to rotate, which accelerates the airflow inside the casing, thereby reducing the heat inside the casing. At the same time, dust in the air enters the casing through the through holes and adheres to the filter screen under the action of the fan blades. At this time, the operator can drive the cleaning frame to rotate through the drive component. The cleaning frame drives the brush to move relative to the filter screen. The brush sweeps the dust off the filter screen and discharges it from the generator under the action of the fan blades. The accumulation of dust inside the casing is reduced, the airflow is smoother, the accumulation of heat inside the generator is reduced, and the service life of the generator is extended.

[0008] Optionally, the driving component includes a plurality of driving gears and a driving gear ring. The cleaning frame is provided with a plurality of locking teeth, which are circumferentially distributed along the axis of the rotor. The plurality of driving gears are circumferentially distributed along the axis of the rotor. The driving gears are rotatably connected to the housing and mesh with the locking teeth. The driving gear ring is coaxially arranged with the rotor and rotatably connected to the housing. The driving gear ring meshes with the driving gears.

[0009] By adopting the above technical solution, when a large amount of dust adheres to the filter screen, the operator can rotate the drive gear ring, which drives the drive gear to rotate. The drive gear drives the cleaning frame to rotate through the locking teeth on the cleaning frame. The brush on the cleaning frame moves relative to the filter screen, thus sweeping off the dust from the filter screen. The dust is then discharged from the generator under the rotation of the fan blades. Several drive gears mesh with several locking teeth on the cleaning frame, and these drive gears limit the position of the cleaning frame, reducing the movement of the cleaning frame within the casing, resulting in a more reasonable structure.

[0010] Optionally, the cleaning assembly further includes a bearing, which is coaxially arranged with the rotor, with the outer ring of the bearing disposed on the cleaning frame and the inner ring of the bearing sleeved on the rotor.

[0011] By adopting the above technical solution, the inner ring of the bearing is fitted onto the rotor, and the outer ring of the bearing is set on the stator, thereby further realizing the positioning of the cleaning frame, and the bearing can reduce the relative friction between the cleaning frame and the rotor.

[0012] Optionally, a limiting ring is provided inside the housing to restrict the cleaning frame from moving toward the through hole.

[0013] By adopting the above technical solution, the drive gear ring and bearing are used to limit the movement of the cleaning frame on the plane where the cleaning frame is located. The limiting ring limits the movement of the cleaning frame relative to the axis of the housing, and the feeding part reduces the movement of the cleaning frame.

[0014] Optionally, the drive gear ring is provided with a handle for easy rotation.

[0015] By adopting the above technical solution, the handle makes it easy for the operator to hold the drive gear ring, which in turn drives the drive gear to rotate, thus facilitating operation.

[0016] Optionally, the housing is provided with a mounting component for fixing the filter screen. The mounting component includes a mounting block and a mounting spring. The mounting block is slidably connected to the housing along the radial direction of the housing. The filter screen is provided with a mounting groove for engaging with the mounting block. The mounting spring is used to keep the mounting block in the mounting groove.

[0017] By adopting the above technical solution, when impurities that cannot be discharged from the filter screen enter the generator, the staff needs to remove the filter screen to remove the impurities. The staff can move the mounting block away from the mounting slot against the elastic force of the mounting spring, and the filter screen can be removed from the housing. This makes it easier for the staff to clean the impurities left in the housing. After cleaning, the filter screen is installed back onto the housing through the mounting parts, which make the filter screen removable.

[0018] Optionally, the mounting block is provided with a guide slope for guiding the mounting block to move away from the mounting groove during filter installation.

[0019] By adopting the above technical solution, during installation, the filter screen abuts against the guide slope, and the guide slope guides the mounting block to move against the elastic force of the mounting spring until the mounting block is aligned with the mounting groove. Under the elastic force of the mounting spring, the mounting block enters the mounting groove, thus completing the installation of the filter screen.

[0020] Optionally, the mounting component further includes a positioning block, which is disposed on the filter screen, and the housing is provided with a positioning groove for engaging the positioning block.

[0021] By adopting the above technical solution, the positioning block on the filter screen and the positioning groove on the housing are used to limit the position of the filter screen, so as to facilitate the smooth entry of the installation block into the installation groove.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The cleaning component is used to clean impurities attached to the filter screen, reducing the accumulation of impurities inside the casing and reducing heat buildup inside the casing, thereby extending the service life of the generator; 2. The mounting bracket is used to install the filter screen onto the housing, making it easier for staff to handle impurities that cannot pass through the filter screen. Attached Figure Description
