Description

Technical Field

[0001] The present invention relates to the field of heat dissipation equipment, and in particular to a heat dissipation structure for a high-speed motor and a use method thereof. Background Art

[0002] High-speed motors are motors that can run at high speeds, usually at thousands of revolutions per minute or even higher, with specific process requirements and performance characteristics. These motors are widely used in a variety of modern industrial and technological fields, including wind power generation, automotive industry, aerospace, electronic equipment and precision machinery.

[0003] When the motor is running, a lot of heat will be generated. If this heat cannot be effectively dissipated, it will cause the motor to overheat, which will affect its performance and even damage the motor itself. Therefore, in order to ensure that the motor can work stably and reliably when running at high speed, the heat dissipation device is used to control and manage the heat of the motor. When the high-speed motor is running, a lot of heat will be generated. If there is no air-cooling structure on the left and right sides of the protection box for heat dissipation, the heat cannot be effectively dissipated, resulting in heat accumulation in the protection box, and the operating temperature of the motor will rise, which may reach or exceed its rated temperature range, thereby affecting the performance and life of the motor. When the high-speed motor is running, the internal heat will rise rapidly. When the internal temperature of the motor is too high, the internal parts and insulation materials of the motor will be damaged, which may accelerate the aging of parts and the occurrence of electrical failures, leading to equipment failure and production stagnation, shortening the life of the motor, requiring more frequent maintenance and higher repair costs, and may pose a potential threat to the working environment and the safety of operators. If the motor is running, the lack of a fixing device will cause the motor to be unable to maintain a stable position and posture during operation. This may cause vibration, noise, and instability of the entire device or system. Summary of the invention

[0015] The present invention also provides a heat dissipation structure for a high-speed motor and a method of using the same. The specific method comprises the following steps:

[0016] Step 1: When the motor drives the second rotating rod to rotate, the first bevel gear on the outside of the second rotating rod will mesh with the two second bevel gears during rotation, thereby achieving a linkage effect. When the motor is running, the air-cooling heat dissipation mechanism will automatically dissipate the heat of the motor and drive the second bevel gear and the internal first rotating rod to rotate. When rotating, the belt will be driven to rotate through the first tensioning wheel on the other end of the first rotating rod.

[0017] Step 2: Connect the right end of the connecting rod to the connecting ring, and drive the fan blades to rotate inside the outer shell through the connecting ring. The heat emitted by the motor inside the protective box is absorbed through the right fan blades, and the cold air is transmitted to the inside of the protective box through the left fan blades to dissipate the heat on the surface of the motor.

[0018] Step three: When cooling the inside of the motor, refrigeration oil is injected into the oil pump through the oil inlet pipe, and then the refrigeration oil is transferred to the inside of each connecting pipe through the first delivery pipe on the output end. The refrigeration oil flows through the connecting pipe to the outside of the cage rotor, and flows into the stator winding and the rotor pole through the gap to dissipate the heat of the device inside the motor. At the same time, the internal parts can also be lubricated to improve the stability and heat dissipation of the motor.

[0019] Step 4: Fix the fixing frame on the outside of the front and rear ends of the casing, connect the bottom plate on the fixing frame to the slider, and connect the fixing frame through the bottom plate to support the fixing frame. After the motor is fixed, insert the slider from the rear of the guide rail into the inside of the guide rail. After the slider is inserted, it will be limited by the limit plate to fix the slider inside the guide rail, and fix the motor in the middle of the protective box to improve the stability and fixing effect of the motor during operation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The air-cooling heat dissipation mechanism provided in the present invention can solve the problem that heat accumulates in the protection box, the operating temperature of the motor rises, and may reach or exceed its rated temperature range, thereby affecting the performance and life of the motor. The fan blades are connected with the fan blades through a support rod, and the connecting rod is placed inside the support rod, and the connecting rod and the second tensioning wheel are supported. The right end of the connecting rod is connected with the connecting ring, and the connecting ring is used to drive the fan blades to rotate inside the shell. The heat emitted by the motor inside the protection box is sucked out by the fan blades on the right, and the cold air is directed to the outside through the fan blades on the left. The inside of the protection box is used to dissipate the heat on the surface of the motor. When the wind is transmitted, the protective cover will be connected through a fixed block and fixed on the surface of the protection box through the protective cover, and the left end of the second tensioning wheel will be supported by the fixed block, so that the rotating second tensioning wheel can be more stable. The railing on the protective cover can prevent external impurities from entering the interior of the protection box and prevent certain harm to the fan blades and the motor, thereby effectively ensuring that the motor can operate within a safe temperature range. This can effectively improve the reliability and service life of the motor, while reducing maintenance costs and safety risks.

[0022] 2. The oil-cooling circulation mechanism can solve the problems that lead to equipment failure and production stagnation, shorten the life of the motor, require more frequent maintenance and higher repair costs, and may pose a potential threat to the working environment and the safety of operators. The refrigeration oil inside the oil tank is extracted through the two adapters on the left wall of the oil tank, and the two adapters are connected through a triple pipe. The two adapters are connected together, and the refrigeration oil inside the two adapters is transferred to the second delivery pipe. The used refrigeration oil is transferred to the oil pump through the coupling pipe on the rear end of the second delivery pipe, and is circulated and cooled again through the first delivery pipe on the output end of the oil pump, so as to effectively manage and control the working temperature of the motor and ensure its stable and efficient operation. It is crucial to improve long-term performance, reliability and safety.

[0023] 3. The guide rail, fixing frame, bottom plate, slider and limit plate can solve the problem that the motor cannot maintain a stable position and posture during operation, which may cause vibration, noise and instability of the entire equipment or system. The fixing frame is fixed to the front and rear ends of the casing and the casing is fixed. The bottom plate on the fixing frame is connected to the slider, and the fixing frame is connected and supported by the bottom plate. After the motor is fixed, the slider is inserted from the rear of the guide rail into the interior of the guide rail. After the slider is inserted, it will be limited by the limit plate to fix the slider in the interior of the guide rail. By setting the guide rail and the fixing frame, the motor is fixed in the middle of the protective box to improve the stability and fixation of the motor during operation, thereby effectively ensuring the safety and stable operation of the motor and the reliability of the system.

[0024] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] When the motor is running, the output end of the motor drives the second rotating rod 4 to rotate. During rotation, the first bevel gear 202 on the outer side of the second rotating rod 4 will mesh with the two second bevel gears 203, and drive the second bevel gear 203 and the internal first rotating rod 204 to rotate. During rotation, the first tensioning wheel 205 on the other end of the first rotating rod 204 will drive the belt 206 to rotate, and then the belt 206 will drive the second tensioning wheel 207 to slide inside the left and right sides of the protective box 1 at the rear end, and rotate inside the support rod 211 through the connecting rod 209 on the right end of the second tensioning wheel 207, connect with the fan blade 212 through the support rod 211, and place it inside the support rod 211 through the connecting rod 209, and support the connecting rod 209 and the second tensioning wheel 207, and connect with the connecting rod 209 through the right end of the connecting rod 209. The connecting ring 210 is connected, and the connecting ring 210 is used to drive the fan blades 212 to rotate inside the shell 208. The heat emitted by the motor inside the protection box 1 is absorbed by the fan blades 212 on the right, and the cold wind is transmitted to the inside of the protection box 1 through the fan blades 212 on the left to dissipate the heat on the surface of the motor. When the wind is transmitted, the protective cover 214 is connected through the fixing block 213 and fixed on the surface of the protection box 1 through the protective cover 214, and the left end of the second tensioning wheel 207 is supported by the fixing block 213, so that the rotating second tensioning wheel 207 can be more stable, and the railing 215 on the protective cover 214 is used to prevent external impurities from entering the interior of the protection box 1, and to prevent certain harm to the fan blades 212 and the motor, thereby effectively improving and ensuring that the motor can operate within a safe temperature range.

[0058] When cooling is performed by the air-cooled heat dissipation mechanism 2, the refrigeration oil is injected into the interior of the oil pump 502 through the oil inlet pipe 503, and then the refrigeration oil is transferred to the interior of each connecting pipe 505 through the first delivery pipe 504 on the output end. The refrigeration oil flows into the outside of the cage rotor 6 through the connecting pipe 505, and flows into the stator winding 7 and the rotor pole 8 through the gap to dissipate the heat of the device inside the motor. While dissipating the heat, the internal parts can also be lubricated to improve the stability and heat dissipation of the motor. When the refrigeration oil is scattered on each part, the refrigeration oil will pass through the parts. The refrigeration oil flows into the oil tank 506 at the bottom of the casing 3 through the holes and gaps, and the refrigeration oil in the oil tank 506 is collected, and the refrigeration oil is extracted through the two adapters 508 on the left side wall of the oil tank 506, and the two adapters 508 are connected through the triple pipe 509. The two adapters 508 are connected together, and the refrigeration oil in the two adapters 508 is transferred to the second delivery pipe 510 together, and the used refrigeration oil is transferred to the oil pump 502 through the coupling pipe 513 on the rear end of the second delivery pipe 510, and is circulated and cooled again through the first delivery pipe 504 on the output end of the oil pump 502.
