Description

Technical Field

[0001] This application relates to the field of electric motors, and more particularly to an energy-saving electric motor. Background Technology

[0002] An electric motor is an energy conversion device that converts electrical energy into mechanical energy, and it is widely used in modern industry and daily life. It mainly works based on the principle of electromagnetic induction. When an electric current passes through a conductor, it generates a magnetic field. This magnetic field interacts with the magnetic field generated by the permanent magnet or other electromagnets inside the motor, producing torque that causes the rotor to rotate, thereby outputting mechanical energy through the shaft.

[0003] To ensure stable motor operation, heat dissipation design is crucial. Currently, by setting vents in the rear cover of the motor and incorporating a cooling fan connected to the shaft, the fan rotates synchronously with the shaft during motor operation, generating airflow to dissipate heat from the motor and achieve energy savings.

[0004] However, in practical applications, especially in high-dust environments such as cement production, dust easily accumulates on the surface of cooling fan blades. Dust buildup significantly reduces the fan's cooling efficiency and increases motor power consumption. Therefore, a motor design is needed that reduces dust accumulation on the fan and lowers its power consumption. Summary of the Invention

[0005] In order to reduce dust accumulation in the fan and lower the power consumption of the motor when operating in an environment with high dust concentration, this application provides an energy-saving motor.

[0006] This application provides an energy-saving motor, which adopts the following technical solution: An energy-saving motor includes a body, a shaft, a cooling fan, a cleaning assembly, and a locking assembly; the shaft is connected to the body, and the cooling fan is rotatably mounted on the shaft; The cleaning assembly includes a support base, a drive mechanism, and a cleaning component. The support base is mounted on the rotating shaft, and the cleaning component is mounted on the drive mechanism. The drive mechanism is used to move the cleaning component closer to or further away from the cooling fan. The locking component is used to lock the position of the cooling fan, so that the cooling fan is relatively fixed to the position of the housing. When the cooling fan is fixed relative to the housing, the drive mechanism causes the cleaning component to abut against the cooling fan; When the locking component unlocks from the cooling fan, the drive mechanism moves the cleaning component away from the cooling fan and causes the rotating shaft to rotate the cooling fan.

[0007] By adopting the above technical solution, at the initial stage of motor startup, the locking component fixes the cooling fan, preventing it from rotating with the shaft. At this time, the drive mechanism controls the cleaning component on the cleaning assembly to approach and abut against the stationary cooling fan. The rotation of the shaft drives the cleaning component to scrape and clean the fan blades, effectively removing the attached dust. When the motor is running normally, the locking component unlocks, and the drive mechanism drives the cleaning component away from the fan blades to reduce wear and interference. At the same time, it drives the cooling fan to rotate synchronously with the shaft for normal heat dissipation.

[0008] Optionally, the drive mechanism includes a drive block, a moving member, and a first elastic member; the drive block is slidably disposed with the rotating shaft, and the first elastic member is located between the rotating shaft and the drive block; the cleaning member is disposed on the moving member; the rotating shaft rotates, causing the moving member to move the cleaning member closer to or away from the cooling fan.

[0009] By adopting the above technical solution, when the motor speed is below the design speed, the cleaning component is in the working position, and at this time, the cleaning component abuts against the cooling fan to perform cleaning. When the motor speed reaches the design speed, the drive block moves under the action of centrifugal force and abuts against the cooling fan, thereby driving the fan to rotate for heat dissipation. At the same time, the moving component causes the cleaning component to move out of the rotation range of the cooling fan. This application realizes the automatic switching between cleaning mode and heat dissipation mode through the centrifugal force generated by the rotation of the shaft.

[0010] Optionally, the movable component includes a mounting base and a second elastic component; The mounting base is slidably connected to the support base, the second elastic element is located between the mounting base and the support base, and the cleaning element is connected to the mounting base; the driving block moves toward the cooling fan, causing the mounting base to drive the cleaning element to move away from the cooling fan.

[0011] By adopting the above technical solution, when the cleaning component comes into contact with the cooling fan for cleaning, the second elastic component can provide a buffer for the cleaning component. Simultaneously, when the motor speed decreases, the second elastic component can drive the mounting base to move closer to the cooling fan, facilitating cleaning of the cooling fan the next time the motor starts.

[0012] Optionally, the mounting base is provided with a clearance surface, and the driving block abuts against and moves with the clearance surface, driving the mounting base to move away from the cooling fan.

[0013] By adopting the above technical solution, the clearance surface enables the drive block to move radially along the shaft, thereby driving the mounting base to move axially along the shaft, thus allowing the cleaning component to move closer to or further away from the cooling fan.

[0014] Optionally, the locking assembly includes a locking connector, a locking block, a third elastic element, and an unlocking mechanism; The locking connector is connected to the outer casing of the machine body, the locking block is slidably disposed on the locking connector, and the third elastic element is disposed between the locking block and the locking connector; the unlocking mechanism is disposed on the rotating shaft, and the unlocking mechanism is used to push the locking block to move away from the rotating shaft.

[0015] By adopting the above technical solution, the locking block can be automatically engaged in the second limiting groove by the elastic force of the third elastic element, thereby achieving automatic locking of the cooling fan. When the shaft speed reaches the design speed, the unlocking mechanism pushes the locking block to disengage from the cooling fan, thereby unlocking the cooling fan.

[0016] Optionally, the unlocking mechanism includes a connecting plate, an unlocking block, and a fourth elastic element; the connecting plate is connected to the rotating shaft, the unlocking block is slidably disposed on the connecting plate, and the fourth elastic element is located between the unlocking block and the connecting plate; the rotating shaft drives the connecting plate to rotate, causing the unlocking block to push the locking block to move.

[0017] By adopting the above technical solution, when the shaft speed is below the design speed, the unlocking block moves away from the locking block under the elastic force of the fourth elastic element. When the shaft speed reaches the design speed, the unlocking block pushes the locking block under the action of centrifugal force, causing the locking block to disengage from the cooling fan, thus unlocking the cooling fan.

[0018] Optionally, the drive mechanism further includes an abutment ball, which is rotatably connected to the drive block and abuts against the mounting base.

[0019] By adopting the above technical solution, the contact ball transforms the sliding friction between the drive block and the mounting base into rolling friction, thereby reducing frictional resistance during the movement process.

[0020] Optionally, it also includes a rear cover, which is disposed on the body, and the cooling fan is disposed inside the rear cover, and the cooling fan is provided with heat dissipation holes.

[0021] By adopting the above technical solution, the rear cover provides protection for the cooling fan and cleaning components, reducing the possibility of external foreign objects intruding. The ventilation holes facilitate airflow, ensuring effective heat dissipation.

[0022] Optionally, the drive mechanism drives the cleaning component to move away from the cooling fan, so that the cleaning component abuts against the rear cover.

[0023] By adopting the above technical solution, during the operation of the cooling fan, the cleaning component moves away from and abuts against the back cover, allowing the cleaning component to clean the dust attached to the back cover, thereby reducing the possibility of dust clogging the heat dissipation holes and affecting the heat dissipation efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the cleaning component and the locking component, at the initial stage of motor startup, the locking component fixes the cooling fan, preventing it from rotating with the shaft. At this time, the drive mechanism controls the cleaning component on the cleaning component to approach and abut against the stationary cooling fan. The rotation of the shaft drives the cleaning component to scrape and clean the fan blades, effectively removing the attached dust. When the motor is running normally, the locking component unlocks, and the drive mechanism drives the cleaning component away from the fan blades to reduce wear and interference. At the same time, it drives the cooling fan to rotate synchronously with the shaft for normal heat dissipation. 2. By setting a drive mechanism, when the motor speed is below the design speed, the cleaning component is in the working position, and at this time, the cleaning component abuts against the cooling fan to perform cleaning. When the motor speed reaches the design speed, the drive block moves under the action of centrifugal force and abuts against the cooling fan, thereby driving the fan to rotate for heat dissipation. At the same time, the moving component causes the cleaning component to move out of the rotation range of the cooling fan. This application realizes automatic switching between cleaning mode and heat dissipation mode through the centrifugal force generated by the rotation of the shaft; 3. During the operation of the cooling fan, the cleaning component moves away from and comes into contact with the back cover, allowing the cleaning component to remove dust adhering to the back cover, thereby reducing the possibility of dust clogging the heat dissipation holes and affecting the heat dissipation efficiency.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] This application discloses an energy-saving motor. For example... Figure 1 and Figure 2 As shown, the energy-saving motor includes a body 1, a rotating shaft 2, a cooling fan 3, a cleaning assembly 4, a locking assembly 5, and a rear cover 6. The rotating shaft 2 is fixedly connected to the rotor inside the body 1, allowing the rotating shaft 2 to rotate.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the cooling fan 3 includes a fan blade seat 31 and a fan blade 32. The fan blade 32 is fixedly connected to the periphery of the fan blade seat 31. The fan blade seat 31 is connected to the rotating shaft 2 through a bearing, so that the fan blade seat 31 can rotate relative to the rotating shaft 2.

[0030] like Figure 4 and Figure 5 As shown, the cleaning component 4 includes a support base 41, a drive mechanism 42, and a cleaning element 43. The drive mechanism 42 includes a drive block 421, a moving element 422, and a first elastic element 423. The moving element 422 includes a mounting base 4221 and a second elastic element 4222. The cleaning element 43 is fixedly mounted on the mounting base 4221. In this embodiment, the cleaning element 43 is a sponge block.

[0031] Specifically, such as Figure 5 and Figure 6As shown, the support base 41 is fixedly connected to the rotating shaft 2, the drive block 421 is slidably connected to the rotating shaft 2, and the mounting base 4221 is slidably connected to the support base 41. One end of the first elastic element 423 is fixedly connected to the drive block 421, and the other end is fixedly connected to the rotating shaft 2. One end of the second elastic element 4222 is fixedly connected to the support base 41, and the other end is fixedly connected to the mounting base 4221. In this embodiment, the first elastic element 423 is a spring, and the second elastic element 4222 is also a spring. The mounting base 4221 is provided with a clearance surface 4223. One end of the drive block 421 enters the support base 41, and under the action of the elastic force of the second elastic element 4222, the drive block 421 abuts against the clearance surface 4223, wherein the clearance surface 4223 is a slope. In addition, an abutment ball 7 is rotatably connected to the drive block 421, which can reduce the friction between the drive block 421 and the clearance surface 4223.

[0032] like Figure 4 and Figure 7 As shown, the locking assembly 5 includes a locking connector 51, a locking block 52, a third elastic element 53, and an unlocking mechanism 54. The unlocking mechanism 54 includes a connecting plate 541, an unlocking block 542, and a fourth elastic element 543. The locking connector 51 is fixedly connected to the outer shell of the body 1. The locking block 52 is slidably connected to the locking connector 51. One end of the third elastic element 53 is fixedly connected to the locking connector 51, and the other end is fixedly connected to the locking block 52. The connecting plate 541 is fixedly connected to the rotating shaft 2. The unlocking block 542 is slidably connected to the connecting plate 541. One end of the fourth elastic element 543 is fixedly connected to the connecting plate 541, and the other end is fixedly connected to the unlocking block 542.

[0033] It should be noted that, as Figure 3 and Figure 5 As shown, the fan blade seat 31 is provided with a first limiting groove 311 and a second limiting groove 312, and the locking block 52 includes an unlocking part 521 and a locking part 522.

[0034] When the motor is not started, the drive block 421 is positioned away from the first limiting groove 311 under the elastic force of the first elastic member 423. Simultaneously, the mounting base 4221, under the elastic force of the second elastic member 4222, keeps the clearance surface 4223 abutting against the drive block 421. Furthermore, the locking block 52, under the elastic force of the third elastic member 53, positions the locking part 522 within the second limiting groove 312, simultaneously pressing against the inner wall of the second limiting groove 312, thus keeping the fan blade seat 31 and the locking connecting seat 51 relatively fixed. The unlocking block 542, under the elastic force of the fourth elastic member 543, is located within the connecting plate 541. Meanwhile, a limiting block 313 is fixedly connected within the second limiting groove 312. When the locking block 52 abuts against the limiting block 313, it restricts the movement of the fan blade seat 31, further improving the reliability of the fan blade seat 31 and the locking connecting seat 51 remaining relatively fixed.

[0035] During the initial startup of the motor, as the rotational speed of the shaft 2 gradually approaches the design speed, the connecting plate 541 rotates along with the shaft 2, causing the unlocking block 542 to gradually move towards the locking block 52 under the action of centrifugal force. Simultaneously, the driving block 421 moves radially along the shaft 2 under the action of centrifugal force, causing it to gradually move towards the first limiting groove 311. Furthermore, since the driving block 421 remains in contact with the clearance surface 4223, as it moves towards the first limiting groove 311, it also drives the mounting base 4221 to move away from the cooling fan 3.

[0036] When the rotating shaft 2 has not reached the designed speed, the cleaning component 43 abuts against the fan blade 32. Since the fan blade seat 31 and the locking connection seat 51 are relatively fixed at this time, the rotating shaft 2 and the fan blade seat 31 can rotate relative to each other. Thus, the cleaning component 43 contacts the surface of each fan blade 32 during the rotation of the rotating shaft 2, thereby cleaning the surface of the fan blade 32.

[0037] When the rotating shaft 2 reaches the designed speed, the unlocking block 542 moves under the action of centrifugal force to abut against the unlocking part 521 of the locking block 52, and pushes the locking block 52 to move away from the rotating shaft 2, so that the locking part 522 disengages from the fan blade seat 31, thereby unlocking the fan blade seat 31. At the same time, under the action of centrifugal force, the driving block 421 moves to abut against the inner wall of the first limiting groove 311, so that the fan blade seat 31 can rotate together with the driving block 421, thereby causing the fan blade 32 to rotate and achieve heat dissipation of the motor.

[0038] Furthermore, as the drive block 421 moves towards the first limiting groove 311, the cleaning component 43, driven by the mounting base 4221, moves out of the rotation range of the fan blade 32, reducing the possibility of interference between the cleaning component 43 and the cooling fan 3 during operation. Specifically, when the rotation speed of the shaft 2 is close to the design speed but has not yet reached it, the cleaning component 43 has already moved out of the rotation range of the fan blade 32.

[0039] like Figure 1 As shown, the rear cover 6 is bolted to the body 1. The rear cover 6 has ventilation holes 61, which protect the cooling fan 3 and the cleaning component 4, reducing the possibility of external foreign objects intruding. The ventilation holes 61 facilitate airflow and ensure effective heat dissipation. Specifically, when the mounting base 4221 moves to its extreme position away from the cooling fan 3 under the drive of the drive block 421, the cleaning component 43 abuts against the rear cover 6. This allows the cleaning component 43 to rotate and clean dust adhering to the rear cover 6 when the cooling fan 3 is dissipating heat, reducing the possibility of dust clogging the ventilation holes 61.

[0040] The implementation principle of an energy-saving motor in this application embodiment is as follows: When the motor is not working, the mounting base 4221, under the action of the second elastic element 4222, positions the cleaning element 43 between the two fan blades 32. At the same time, under the action of the elastic force of the third elastic element 53, the locking block 52 abuts against the inner wall of the second limiting groove 312, so that the fan blade seat 31 and the locking connection seat 51 remain relatively fixed.

[0041] During motor operation, as the rotational speed of shaft 2 gradually approaches the design speed, drive block 421 moves towards the first limiting groove 311 under centrifugal force, simultaneously driving mounting base 4221 to move away from fan blade 32, causing cleaning component 43 to gradually move away from the rotation range of fan blade 32. When cleaning component 43 is within the range of fan blade 32, it contacts fan blade 32, achieving cleaning of fan blade 32. Additionally, unlocking block 542 moves towards locking block 52 under centrifugal force.

[0042] When the rotational speed of the shaft 2 is close to the design speed but not reached, the drive block 421 drives the mounting base 4221 to move to the limit position. At this time, the cleaning component 43 is removed from the rotation range of the fan blade 32. At the same time, the cleaning component 43 abuts against the rear cover 6 to clean the rear cover 6.

[0043] When the rotational speed of the shaft 2 reaches the design speed, the unlocking block 542 pushes the unlocking part 521, causing the locking block 52 to disengage from the second limiting groove 312. At the same time, the drive block 421 presses against the first limiting groove 311, allowing the fan blade seat 31 to rotate together with the shaft 2, thereby dissipating heat from the motor.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
