Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a three-phase asynchronous motor for an energy storage system. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor. It is a type of motor that is powered by a 380V three-phase AC current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion.

[0003] Announcement No. CN217849105U discloses a three-phase asynchronous motor, including a motor assembly, wherein the motor assembly includes a motor body and a heat dissipation assembly, wherein the heat dissipation assembly includes a connecting pipe, wherein one end of the motor body is provided with a connecting pipe, wherein a plurality of heat dissipation copper sheets are provided inside the connecting pipe, and a heat dissipation fan is also provided inside the connecting pipe and at one end away from the motor body. Although the heat dissipation assembly is provided for this kind of three-phase asynchronous motor, the heat inside the motor body can be guided to prevent the heat from accumulating inside the motor body, so that the device inside the motor body can be operated normally and the device can be prevented from being damaged. However, the air outlet of this kind of three-phase asynchronous motor is prone to dust accumulation and may be entangled by fibers, which not only affects the heat dissipation effect of the motor, but also may cause the air outlet to be blocked. Cleaning these dust and fibers usually requires complicated operations, which increases the maintenance difficulty and workload of the staff, and also affects the normal operation and life of the equipment. Therefore, improvements are needed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a three-phase asynchronous motor for an energy storage system.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a three-phase asynchronous motor for an energy storage system, comprising a three-phase asynchronous motor body, an output shaft is installed at the output end of the three-phase asynchronous motor body, a side shell is fixedly installed on the side of the three-phase asynchronous motor body, a motor is fixedly installed on the inner side of the side shell, a fan is installed at the output end of the motor, an air outlet is opened on the surface of the side shell, a rotating shaft is rotatably connected to the surface of the side shell, a vertical plate is fixedly installed at one end of the rotating shaft, and a scraper is fixedly installed on the inner side of the vertical plate.

[0006] Preferably, the scrapers are symmetrically distributed on the inner side of the vertical plate, and the side shell is made of austenitic stainless steel, thereby increasing the service life of the side shell.

[0007] Preferably, a mounting plate is fixedly mounted on the bottom surface of the three-phase asynchronous motor body, and the mounting plates are symmetrically distributed on the bottom surface of the three-phase asynchronous motor body.

[0008] Preferably, the air outlets are arranged in a circular shape on the surface of the side shell.

[0010] Preferably, the material of the plug rod is ferritic stainless steel, and the plug rod is the same size as the plug hole.

[0011] Preferably, the slot and the insert block are matched in size.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model can accelerate the dissipation of heat generated during the operation of the motor by setting an air outlet and utilizing a fan driven by a motor, thereby ensuring that the motor can maintain a low operating temperature when operating under high load or for a long time, thereby extending the service life of the motor. During the operation of the motor, dust is easily accumulated at the air outlet, which may affect the heat dissipation effect and even cause blockage. By using a pushable vertical plate and a scraper mechanism, the staff can easily remove the dust on the air outlet and the side shell, keep the air outlet unobstructed, and thus ensure the heat dissipation effect. While cleaning the dust, the scraper can also cut off fibers that may be entangled in the air outlet, which not only keeps the air outlet clean, but also avoids blockage of the air outlet due to fiber entanglement, further ensuring the effectiveness of the heat dissipation system.

[0014] 2. The utility model can effectively protect the output shaft from external physical impact or dust pollution by providing a protective shell, thereby reducing the risk of possible damage during transportation, and through a simple plug-in design, the protective shell can be easily and quickly installed on the output shaft, and the disassembly is also easy, which greatly improves the convenience of operation. At the same time, by utilizing the magnetic force between the magnet and the plug rod, the protective shell can be stably fixed on the output shaft, ensuring that the protective shell will not accidentally fall off during transportation. Through the design of the plug block and the slot, not only the fixation of the protective shell is achieved, but also the change in the angle of the output shaft can be effectively limited, thereby preventing unnecessary rotation of the output shaft during transportation, further enhancing the protection effect.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0024] See also Figure 1-5 The utility model provides a technical solution: a three-phase asynchronous motor for an energy storage system, comprising a three-phase asynchronous motor body 1, and an output shaft 2 is installed at the output end of the three-phase asynchronous motor body 1. A mounting plate 3 is fixedly installed on the bottom surface of the three-phase asynchronous motor body 1, and the mounting plate 3 is symmetrically distributed on the bottom surface of the motor body, providing a stable installation foundation for the three-phase asynchronous motor body 1. The mounting plate 3 can be firmly connected to the workbench or equipment foundation by bolts, welding or other commonly used fixing methods such as riveting, bonding, etc. A side shell 4 is fixedly installed on the side of the three-phase asynchronous motor body 1. The material of this side shell 4 is austenitic stainless steel. This material is not only strong and durable, but also has excellent corrosion resistance, and is very suitable for use in application scenarios such as the three-phase asynchronous motor body 1 that require long-term operation and changeable environment. A motor 5 is fixedly installed on the inner side of the side shell 4, which is a key component for driving the fan 6 to rotate. The motor 5 is connected to the fan 6 through its output end. When the motor 5 is started, it drives the fan 6 to rotate at high speed. This design can significantly increase the air circulation speed, thereby helping the three-phase asynchronous motor body 1 to dissipate heat more effectively during operation. The side shell 4 is also provided with air outlets 7, which are arranged in a circumferential shape on the surface of the side shell 4 to ensure uniformity and efficiency of heat dissipation. When the fan 6 rotates, it will quickly discharge the heat generated inside the three-phase asynchronous motor body 1 through the air outlets 7, thereby maintaining the operating temperature of the three-phase asynchronous motor body 1 within a safe range.

[0025] See also Figure 1-5 , there is a rotatable vertical plate 9 on the surface of the side shell 4, and this vertical plate 9 is connected to the side shell 4 through the rotating shaft 8. When there is dust remaining on the air outlet 7, the staff only needs to gently push the vertical plate 9, and the vertical plate 9 will rotate flexibly through the rotating shaft 8. At the same time, a scraper 10 is fixedly installed on the inner side of the vertical plate 9, and these scrapers 10 will scrape the surface of the side shell 4 when the vertical plate 9 rotates, so as to easily remove the attached dust. This design not only simplifies the cleaning process, but also ensures the smooth flow of the air outlet 7, and further improves the heat dissipation effect. In addition to removing dust, the scraper 10 also has the function of cutting off fibers. In the environment where the three-phase asynchronous motor body 1 is running, some fibers may be entangled at the air outlet 7, which will not only affect the heat dissipation effect, but also may threaten the normal operation of the three-phase asynchronous motor body 1. The cutting function of the scraper 10 can effectively solve this problem. It can easily cut off the fibers entangled at the air outlet 7 and keep the air outlet 7 clean and smooth. Example 2

[0026] See also Figure 4-5, a protective mechanism is provided on the side of the three-phase asynchronous motor body 1, and the protective mechanism includes a protective shell 11, which is provided on the surface of the output shaft 2. The protective shell 11 not only plays a role of physical protection, but also can prevent dust pollution and physical impact during transportation or handling. The surface of the protective shell 11 is equipped with a plug rod 12 in a fixed installation manner. The material of these plug rods 12 is ferritic stainless steel, which is not only strong and durable, but also has a good magnetic effect with the magnet. The surface of the three-phase asynchronous motor body 1 is correspondingly provided with a plug hole 13, and the size of these plug holes 13 is completely matched with the plug rod 12 to ensure that the plug rod 12 can be smoothly inserted. The surface of the output shaft 2 is also provided with a slot 14, which matches the plug block 15 fixedly installed on the inner wall of the protective shell 11. When the plug block 15 is inserted into the slot 14, it can not only further stabilize the protective shell 11, but also effectively limit the angle change of the output shaft 2 to prevent unnecessary rotation during transportation or storage. The inner wall of the socket 13 is also cleverly fixed with a magnet. When the insertion rod 12 is inserted into the insertion hole 13 , the magnet will attract the insertion rod 12 made of ferrite stainless steel, and the protective shell 11 will be firmly fixed on the surface of the output shaft 2 by the magnetic force.

[0027] Working principle: Ventilation can be carried out through the arranged air outlet 7. During the operation of the three-phase asynchronous motor body 1, the heat generated can be dissipated through the air outlet 7. At the same time, the motor 5 drives the fan 6 to rotate, which can further increase the air circulation speed, thereby improving the heat dissipation effect. When dust remains at the air outlet 7, the staff can push the vertical plate 9, and the vertical plate 9 rotates through the rotating shaft 8 at this time. At the same time, the vertical plate 9 can drive the scraper 10 to scrape the surface of the side shell 4, and the attached dust can be removed at this time. At the same time, the scraper 10 can also cut off the fiber, thereby preventing the fiber floc from being entangled at the air outlet 7. The utility model can speed up the electric motor by arranging the air outlet 7 and using the fan 6 driven by the motor 5. The heat generated during the operation of the motor can be dissipated, thereby ensuring that the motor can maintain a low operating temperature when it is under high load or works for a long time, thereby extending the service life of the motor. During the operation of the motor, dust is easily accumulated at the air outlet 7, which may affect the heat dissipation effect and even cause blockage. By pushing the vertical plate 9 and the scraper 10 mechanism, the staff can easily remove the dust on the air outlet 7 and the side shell 4, keep the air outlet 7 unobstructed, and thus ensure the heat dissipation effect. While cleaning the dust, the scraper 10 can also cut off the fibers that may be entangled at the air outlet 7, which can not only keep the air outlet 7 clean, but also avoid the blockage of the air outlet 7 caused by fiber entanglement. By setting the protective shell 1 1 can protect the output shaft 2, especially when the three-phase asynchronous motor body 1 needs to be transported or carried, the staff can align the protective shell 11 with the output shaft 2 and insert it, and then align the plug rod 12 with the plug hole 13 and insert it. At this time, the protective shell 11 can be limited. At the same time, the plug rod 12 can resist the magnet after being inserted into the plug hole 13. At this time, the magnet can absorb the ferrite stainless steel plug rod 12 due to the magnetic force. At this time, the protective shell 11 can be limited on the surface of the output shaft 2, and the plug block 15 can be inserted into the slot 14. In this way, the angle of the output shaft 2 can be limited, thereby preventing the output shaft 2 from rotating during transportation. The utility model can effectively protect the output shaft 2 by setting the protective shell 11. The output shaft 2 is protected from external physical impact or dust pollution, thereby reducing the risk of possible damage during transportation, and through a simple plug-in design, the protective shell 11 can be easily and quickly installed on the output shaft 2, and disassembly is also easy, which greatly improves the convenience of operation. At the same time, by utilizing the magnetic force between the magnet and the plug rod 12, the protective shell 11 can be stably fixed on the output shaft 2, ensuring that the protective shell 11 will not accidentally fall off during transportation. Through the design of the plug block 15 and the slot 14, not only the fixing of the protective shell 11 is achieved, but also the change in the angle of the output shaft 2 can be effectively limited, thereby preventing unnecessary rotation of the output shaft 2 during transportation, further enhancing the protection effect.
