Description

Technical Field

[0001] This invention relates to the field of motor technology for industrial ceiling fans, specifically to an energy-saving motor for industrial ceiling fans with high-efficiency heat dissipation. Background Technology

[0002] Industrial ceiling fans, also known as HVLS large-diameter energy-saving ceiling fans, are mainly used in large, open spaces such as factories, warehouses, and stadiums. They rely on large fan blades rotating at low speed to drive a large volume of air to form a three-dimensional circulation, achieving ventilation, cooling, dehumidification, deodorization, and equalization of space temperature. Industrial ceiling fans are equipped with energy-saving motors, using high-efficiency drive technology and optimized electromagnetic design, resulting in low operating losses and high conversion efficiency, significantly reducing energy consumption compared to traditional motors. The motors operate smoothly with low noise, excellent temperature rise control, high durability, and longer maintenance cycles, continuously and stably driving large fan blades to form a wide-range, gentle airflow. They balance the ventilation and cooling needs of large-area factories with long-term electricity cost control, achieving energy saving and consumption reduction while ensuring ventilation effects. They are suitable for various large-space scenarios such as factory workshops, warehouses, logistics facilities, and large stadiums.

[0003] Chinese patent CN117937799A discloses an industrial ceiling fan motor, including a boom shaft, a stator assembly, a rotor assembly, and a motor housing. The stator assembly includes a hub fixed to the boom shaft and a stator core mounted on the hub. Ventilation holes are spaced apart on the outer wall of the hub and / or the inner wall of the stator core. The motor housing includes an upper cover and a lower cover, both of which have heat dissipation holes. The inner sidewall of the lower cover has a circumferential array of raised fan blades. This invention, by providing fan blades on the lower cover, ventilating holes spaced apart on the outer wall of the hub and / or the inner wall of the stator core, and heat dissipation holes on the upper and lower covers, allows the fan blades to generate airflow when the motor rotates. This airflow, forming a cooling channel between the ventilating holes and the heat dissipation holes, carries away the hot air inside the motor and the oily acid pickling gases generated during motor operation, effectively ensuring the motor's heat dissipation performance. The heat dissipation method of this technical solution relies solely on internal convection within the motor's built-in blades, resulting in limited heat dissipation intensity. Hot airflow easily accumulates on the top of the motor, and the heat dissipation holes are open structures. In dusty factory environments, dust continuously enters the motor through the heat dissipation holes when the machine is stopped, easily clogging the air duct. As dust accumulates, ventilation efficiency continuously decreases, requiring frequent manual maintenance. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an energy-saving motor for an industrial ceiling fan with high-efficiency heat dissipation, comprising: A bottom shell, the top of which is fixedly connected to an upper shell, and an iron core is provided between the upper shell and the bottom shell. A main shaft is fixedly connected to the top of the upper shell. It also includes heat dissipation slots evenly distributed on the top of the upper shell, and heat dissipation components fixedly connected to the top of the upper shell; Furthermore, the heat dissipation component includes a heat dissipation cylinder fixedly connected to the top of the upper shell, a heat dissipation plate fixedly connected to the top of the heat dissipation cylinder, a driving component fixedly connected to the inner side of the heat dissipation plate, and a fan blade rotatably connected to the bottom of the inner cavity of the heat dissipation cylinder. The top of the fan blade is rotatably connected to the bottom of the heat dissipation plate, and a gear disk is fixedly connected to the inner side of the fan blade. Furthermore, there is a gear set rotatably connected to the bottom of the heat sink cavity. The top of the gear set is fixedly connected to the output end of the drive component. The side of the gear set meshes with the inner side of the gear disk. Heat dissipation vents are evenly opened at the bottom of the heat sink, and the heat dissipation vents correspond to the heat dissipation grooves on the top of the upper shell. There are also sliding grooves evenly opened on the side of the heat sink. The side of the sliding groove is evenly provided with exhaust vents. Guide grooves are provided on both sides of the sliding groove. A sliding mechanism is slidably connected to the inner side of the sliding groove. The drive component, in conjunction with the gear meshing, drives the fan blades inside the heat sink to rotate, actively drawing in the hot air generated by the motor and discharging it through the side wall exhaust vents, forming forced convection heat dissipation, reducing the temperature rise of the motor, delaying insulation aging and magnet demagnetization. At the same time, when the motor is working, the upper shell and the bottom shell rotate synchronously, driving the sliding mechanism to slide and automatically open the exhaust vents, realizing the mechanical linkage between the exhaust channel and the motor operation status. The heat dissipation path is synchronously connected when the equipment is running, and the heat dissipation airflow is discharged smoothly. After the machine stops, the exhaust vents can be closed to block dust from entering the heat sink and reduce dust accumulation and blockage in the air duct. Furthermore, the sliding mechanism includes a connecting shaft evenly arranged inside the heat sink cylinder, the side of the connecting shaft being slidably connected to the inside of the heat sink cylinder, a sliding plate being fixedly connected to one end of the connecting shaft, a connecting spring being sleeved on the connecting shaft, one end of the connecting spring being fixedly connected to the inside of the sliding groove, and the other end of the connecting spring being fixedly connected to the sliding plate. Furthermore, a guide plate is fixedly connected to the middle of the sliding plate. The guide plate is inclinedly arranged on the sliding plate. The side of the sliding plate is slidably connected to the inner side of the sliding groove. A scraper frame is fixedly connected to the side of the sliding plate away from the connecting shaft. The side of the scraper frame contacts the inner side of the sliding groove. A contact plate is fixedly connected to the side of the scraper frame away from the guide plate via a round shaft. The round shaft on the contact plate is slidably connected to the inner side of the guide groove. The contact plate contacts the exhaust port. During the entire process of opening and resetting the sliding plate, the scraper and the contact plate drive the exhaust port to clean it bidirectionally, continuously removing surface dust and preventing the exhaust port from being blocked and affecting heat dissipation. In the stopped state, the connecting spring drives the sliding plate to reset and block the exhaust port, preventing external dust from entering the heat dissipation cylinder. The scraper frame is stored inside the sliding groove to avoid the scraper being exposed and accumulating dust during idle periods.

[0005] This invention provides an energy-saving motor for industrial ceiling fans with high-efficiency heat dissipation. It has the following beneficial effects: 1. This energy-saving motor for industrial ceiling fans with high-efficiency heat dissipation allows the hot air generated by the motor to flow upward naturally due to buoyancy. The hot air can enter the heat dissipation cylinder through the heat dissipation slots at the top of the upper shell and the heat dissipation vents at the bottom of the heat dissipation cylinder. The fan blades inside the heat dissipation cylinder rotate continuously, actively forming a suction airflow that continuously guides the hot air inside the motor into the heat dissipation cylinder and exhausts it outward from the exhaust vents on the side wall. Unlike simply relying on natural heat dissipation, this active suction enhances the convection heat transfer in the cavity, quickly dissipates the heat generated by the motor operation, and reduces the operating temperature of the stator windings and permanent magnets.

[0006] 2. The energy-saving motor of this high-efficiency heat dissipation industrial ceiling fan can actively and forcibly dissipate the heat accumulated by the motor during continuous operation, avoiding local heat accumulation. At the same time, the exhaust port is only opened during operation, which can prevent external dust from entering the heat sink through the exhaust port and avoid dust accumulation and blockage of the heat dissipation duct.

[0007] 3. The energy-saving motor of this high-efficiency heat dissipation industrial ceiling fan has an inclined air guide plate on the sliding plate. When the motor rotates, the airflow generated compresses the air guide plate, and the centrifugal force pushes the sliding plate along the sliding groove, compressing the connecting spring. This causes the connecting plate to move away, removing the obstruction to the exhaust vent, and the exhaust channel to open automatically, ensuring that the hot airflow inside the heat dissipation cylinder is smoothly discharged to the outside.

[0008] 4. The energy-saving motor of this high-efficiency heat dissipation industrial ceiling fan can drive the scraper frame and contact plate to continuously clean the exhaust port during the reciprocating opening and closing of the sliding plate, removing dust attached to the air port and preventing dust accumulation from clogging the exhaust port.

[0009] 5. The energy-saving motor of this high-efficiency heat dissipation industrial ceiling fan, after the equipment stops, the connecting spring pushes the sliding plate to reset, sealing the exhaust port, thus preventing external dust and debris from entering the heat dissipation cylinder when idle, avoiding internal dust accumulation. The sliding plate continues to reset until the scraper frame abuts against the inner wall of the sliding groove, storing the entire scraper frame inside the sliding groove, preventing the scraper from being exposed. During idle periods, this prevents dust and debris from continuously adhering to the scraper surface and prevents the scraper from being covered by dust. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Please see Figures 1-3 This invention provides an energy-saving motor for industrial ceiling fans with high-efficiency heat dissipation. After the device is powered on, the control system receives a start signal, the motor driver connects to electrical energy, and converts the AC power into variable frequency DC power adapted to the operation of the motor. The motor relies on an optimized electromagnetic structure to reduce core loss and winding copper loss, thereby converting electrical energy into mechanical energy and outputting a stable torque to drive the large fan blades to operate at low speed. The fan blades 45° stir the air to form a large-scale circulating airflow. Meanwhile, the heat generated by the motor enters the heat dissipation component 4 through the heat dissipation slot 5 opened at the top of the upper shell 1. The heat dissipation component 4 completes the heat dissipation and exhaust, realizing continuous heat dissipation of the motor during operation. Example 1, please refer to Figures 4-7 The present invention provides an energy-saving motor for industrial ceiling fans with high efficiency heat dissipation. When the motor is working, the hot air generated inside moves upward. The hot air flows upward through the heat dissipation grooves 5 evenly opened on the top of the motor upper shell 1, and enters the inner cavity of the heat dissipation cylinder 41 through the heat dissipation ports 48 at the bottom of the heat dissipation cylinder 41 that correspond one-to-one with the heat dissipation grooves 5. A drive unit 43 is installed on the heat dissipation plate 42 at the top of the heat dissipation cylinder 41. The output end of the drive unit 43 drives the gear set 46 to rotate at the bottom of the inner cavity of the heat dissipation cylinder 41. At the same time, the gear set 46 meshes with the gear disk 44 to drive the gear disk 44 to rotate, which in turn drives the fan blades 45 inside the heat dissipation cylinder 41 to rotate continuously. The fan blades 45 continuously guide the hot airflow generated by the motor into the heat dissipation cylinder 41 and discharge it to the outside through the exhaust ports 49 evenly opened on the side wall of the heat dissipation cylinder 41, thus completing the heat dissipation and cooling of the motor during operation. When the motor drives the main fan blades to run, it synchronously drives the upper shell 1 and the bottom shell 2 to rotate. The sliding mechanism 47 moves along the sliding groove 411, so that the exhaust port 49 is automatically opened during the operation of the fan blades 45, ensuring that hot air can be discharged to the outside through the exhaust port 49 during the operation of the motor. Example 2, please refer to Figures 8-9 This invention provides an energy-saving motor for industrial ceiling fans with high-efficiency heat dissipation. The stator inside the motor is fixedly connected to the hanging rod installed above and always remains stationary. The outer upper shell 1 and bottom shell 2 are connected to the output flange and the main fan blade 45. When powered on, the upper shell 1 and bottom shell 2 rotate and directly drive the fan blade 45 to rotate synchronously, so that the outer shell and the fan blade 45 rotate at the same speed. A guide plate 474 is inclined at the middle of the sliding plate 473. When the upper shell 1 and the bottom shell 2 rotate, the airflow acts on the guide plate 474 and is superimposed with centrifugal force, which drives the guide plate 474 to move the sliding plate 473 along the sliding groove 411. The sliding plate 473 moves through the connecting shaft 471 and presses the connecting spring 472 sleeved on the connecting shaft 471, causing the sliding plate 473 to disengage from the evenly spaced exhaust vents 49 on the side wall of the heat sink 41 and release the blockage. Furthermore, the hot air inside the heat sink 41 can be discharged outward through the exhaust port 49 under the airflow driven by the internal fan blades 45, thereby achieving heat dissipation; The sliding plate 473 slides while simultaneously driving the scraper frame 475 on the side and the contact plate 476 on the inner side to clean the exhaust vent 49, preventing dust accumulation from clogging the vent and thus reducing ventilation performance. After the motor stops running, the upper shell 1 and the bottom shell 2 stop rotating. The sliding plate 473 slides back to its original position along the sliding groove 411 under the reset force of the connecting spring 472, which causes the sliding plate 473 to close the exhaust port 49 and prevent external dust and impurities from entering the heat sink 41 when the machine stops. During the reset process of the sliding plate 473, the scraper frame 475 and the contact plate 476 move along both sides of the exhaust port 49 to clean. The contact plate 476 is guided and limited in the guide grooves 410 on both sides of the sliding groove 411 by a round shaft. It completes the cleaning while blocking the exhaust port 49. The sliding plate 473 continues to reset until the scraper frame 475 abuts against the inner wall of the sliding groove 411, and the scraper frame 475 is stored in the sliding groove 411 to avoid dust accumulation on the scraper frame 475 when it is idle, which would affect the cleaning work.

[0014] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
