[0002] High-voltage motors are motors that are suitable for operation under high power supply voltage conditions and are usually used in large industrial equipment. In order to effectively handle the heat generated inside the motor, ventilation and heat dissipation devices are designed to dissipate the heat generated during operation. This type of motor will generate a certain amount of energy loss during operation. Through ventilation systems such as heat sinks, fans or coolant circulation systems, external air can flow through the motor housing and take away the internal heat to keep the motor running within a suitable operating temperature range. The use of ventilation and heat dissipation devices helps maintain the efficient and stable operation of the motor and extend the life of the equipment, which is especially important for equipment such as high-voltage motors that operate in high-voltage environments.

[0003] In the prior art, most of the high-voltage motor ventilation and heat dissipation devices use a three-three fan to blow cold air into the inside of the casing for heat dissipation during use.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2 , the utility model provides an embodiment: a high-voltage motor ventilation and heat dissipation device, including a shell 1, characterized in that: a mounting plate 2 is fixedly connected to one side of the upper surface of the shell 1, a through hole 3 is penetrated inside the mounting plate 2, an air duct pipe 4 is fixedly connected to the upper surface of the mounting plate 2, an air outlet 5 is penetrated inside the air duct pipe 4, a motor 6 is fixedly connected to one side of the outer wall of the air duct pipe 4, a heat dissipation component is arranged at the output end of the motor 6, a mounting ring 8 is arranged at one side of the outer wall of the air duct pipe 4, a barrier net 9 is fixedly connected to the inner wall of the mounting ring 8, and a control box 10 is fixedly connected to one side of the outer wall of the shell 1; the heat dissipation component includes a wind wheel 7, one side of the outer wall of the wind wheel 7 is fixedly connected to the output end of the motor 6, and the wind wheel 7 is rotatably connected to the inner wall of the air duct pipe 4;

[0024] Specifically, first of all, the core of the heat dissipation system lies in the start-up of the motor 6. When the motor 6 starts, it drives the wind wheel 7 to rotate inside the air duct 4. This design cleverly utilizes the airflow generated by the rotation of the wind wheel 7 to extract the heat inside the shell 1 through the through hole 3. When the hot air flows through the air outlet 5, it will be effectively discharged, thereby reducing the temperature inside the shell 1 and ensuring the normal operation of the equipment. In addition, in order to prevent dust and impurities from entering the shell 1, the heat dissipation system is also cleverly provided with a mounting ring 8 and a barrier net 9. The design of the mounting ring 8 makes the entire heat dissipation system more stable and not easy to loosen, thereby ensuring the stability of the heat dissipation effect. The barrier net 9 plays a role in preventing impurities from entering the shell 1, effectively protecting the electronic components inside the device from external pollution.

[0025] Reference Figure 3 , Figure 4, a plurality of mounting blocks 11 are fixedly connected to one side of the outer wall of the shell 1, and the mounting block 11 is penetrated with an opening 12; a telescopic rod 13 is fixedly connected to one side of the inner wall of the mounting block 11, and a spring 14 is sleeved on the outer wall of the telescopic rod 13; a sliding plate 15 is fixedly connected to one end of the spring 14, and a limit block 16 is fixedly connected to one side of the outer wall of the sliding plate 15, and the outer wall of the limit block 16 is slidably connected to the inside of the mounting block 11; a card block 17 is fixedly connected to one side of the outer wall of the sliding plate 15, and the card block 17 is arranged inside the mounting block 11; a mounting column 18 is slidably connected inside the mounting block 11, and the mounting column 18 is slidably connected to the inner wall of the opening 12, and a mounting frame 19 is fixedly connected to the upper surface of the mounting column 18, and a filter screen 20 is fixedly connected inside the mounting frame 19; a spring 21 is slidably connected inside the mounting column 18, and both ends of the spring 21 are fixedly connected to a card block 22, and the card block 17 is slidably connected to the inside of the mounting column 18;

[0026] Specifically, when the heat dissipation device starts to operate, the external cold air enters the interior of the housing 1 through the carefully designed filter 20. The existence of the filter 20 not only filters the dust and impurities in the air to ensure that the interior of the device is not polluted, but also increases the air intake, so that the cold air can quickly flow through the interior of the housing 1, thereby effectively reducing the internal temperature. This design not only improves the heat dissipation efficiency, but also greatly extends the service life of the device. However, as time goes by, a large amount of dust will inevitably accumulate on the surface of the filter 20. The accumulation of dust will not only affect the air intake and reduce the heat dissipation effect, but may also cause damage to other components inside the device. In order to solve this problem, the heat dissipation device is designed with a convenient cleaning and replacement mechanism. The user only needs to press the card block 22, and then pull the mounting frame 19, and the mounting column 18 will be separated from the inside of the mounting block 11. In this process, the card block 17 will be separated from the inside of the mounting column 18 and squeeze the spring 14. This design cleverly allows the sliding plate 15 to retract into the inside of the mounting block 11, thereby providing convenience for replacing and cleaning the filter 20. Through this design, users can easily replace and clean the filter 20 without disassembling the entire heat dissipation device. This not only improves the maintenance convenience of the equipment, but also greatly reduces the user's cost of use. It is worth mentioning that the design of the heat dissipation device also fully considers environmental protection and sustainability. The material of the filter 20 is recyclable, and the replacement process is simple and quick, which helps to reduce the generation of electronic waste and conforms to the green development concept of modern society.

[0027] Working principle: when the high-voltage motor needs to be cooled, the motor 6 is started, and the motor 6 drives the wind wheel 7 to rotate inside the air duct 4. The setting of the wind wheel 7 facilitates the extraction of the heat inside the housing 1 through the through hole 3. At this time, the heat is discharged through the air outlet 5, thereby preventing dust from entering the housing 1. The setting of the mounting ring 8 and the barrier net 9 facilitates the effect of blocking impurities from entering the housing 1.

[0028] Secondly, when the heat dissipation device is in operation, external cold air is filtered through the filter 20 and enters the shell 1, thereby achieving the effect of increasing the air intake to quickly cool down the inside of the shell 1. After a long time, there will be a lot of dust on the surface of the filter 20. At this time, by pressing the block 22 and pulling the mounting frame 19, the mounting column 18 is separated from the mounting block 11. When the mounting column 18 moves, the block 17 will separate from the mounting column 18 and squeeze the spring 14, thereby achieving the effect of driving the sliding plate 15 to retract into the mounting block 11, thereby achieving the effect of facilitating the replacement of the filter 20 for cleaning.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
