Description

Technical Field

[0001] This invention belongs to the field of generator technology, and specifically discloses a single-phase and three-phase equal-power AC synchronous generator. Background Technology

[0002] To ensure the stability of existing single-phase and three-phase AC synchronous generators with equal power, ventilation slots are typically created on the surface of the casing. Rotating blades, mounted coaxially with the shaft, accelerate internal airflow to achieve heat dissipation. To prevent external dust and impurities from entering the generator through the ventilation slots and affecting operational safety, these slots are usually covered with fixed filters.

[0003] However, this type of natural ventilation and heat dissipation structure has certain limitations in practical applications. Its ventilation area is fixed, relying entirely on the continuous rotation of the blades for air exchange. When the generator operates continuously for extended periods under harsh conditions such as high load and high temperature, the internal temperature rises rapidly. At this time, the fixed ventilation area cannot adaptively adjust to actual temperature changes. If heat cannot be dissipated in time, excessively high temperatures will directly affect the generator's output efficiency and lifespan, and may even lead to safety accidents such as insulation aging and burnout. Therefore, those skilled in the art have proposed a single-phase and three-phase equal-power AC synchronous generator to solve the problems mentioned above. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to propose a single-phase and three-phase equal-power AC synchronous generator to solve the problem that the ventilation area of ​​the prior art is fixed and cannot be adaptively adjusted according to the actual temperature change.

[0005] To achieve the above objectives, the present invention provides a single-phase and three-phase equal-power AC synchronous generator, comprising a generator body and a shaft. The shaft is disposed inside the generator body, with one end of the shaft extending through the generator body. An inner partition is embedded in one side of the generator body, and the other end of the shaft extends through the inner partition. Single-phase terminals and three-phase terminals are provided on the surface of the generator body. A heat dissipation component is provided at one end of the generator body. An auxiliary component is provided on the surface of the generator body. A uniformly distributed first ventilation slot is formed on the side of the generator body away from the heat dissipation component. A uniformly distributed ventilation hole is formed on the surface of the inner partition. The heat dissipation assembly includes a detachable end cap disposed at one end of the generator body and used to cover the inner partition. The surface of the end cap is provided with evenly distributed second ventilation slots, and the inner walls of the first ventilation slot and the second ventilation slot are fixedly connected with filter screens.

[0006] In the above technical solution, preferably, an installation plate is fixedly connected to the inner side of the end cap, a bearing is embedded in the center of the installation plate, one end of the rotating shaft is fixedly connected to the inner wall of the bearing, and the surface of the installation plate is provided with uniformly distributed through holes.

[0007] In the above technical solution, preferably, the surface of the rotating shaft is fixedly connected to a mounting ring located between the inner partition and the mounting plate, and the surface of the mounting ring is fixedly connected to uniformly distributed blades.

[0008] In the above technical solution, preferably, the auxiliary component includes an arc-shaped ring embedded in the surface of the generator body, the surface of the arc-shaped ring is provided with uniformly distributed air guide grooves, and the inner side of the arc-shaped ring is provided with a groove.

[0009] In the above technical solution, preferably, the inner wall of the groove is fixedly connected with uniformly distributed heat-conducting strips, and both the arc-shaped ring and the heat-conducting strips are aluminum metal components.

[0010] In the above technical solution, preferably, the arc-shaped ring has a uniformly distributed connecting cavity inside, the inner wall of the air guide groove is provided with a baffle, both ends of the baffle are fixedly connected to a connecting shaft, and the other end of the connecting shaft passes through the arc-shaped ring and extends into the interior of the connecting cavity.

[0011] In the above technical solution, preferably, two symmetrically distributed connecting plates are fixedly connected to the surface of the connecting shaft. The connecting plates are rotatably connected to the inner wall of the connecting cavity. A spring is provided between the two connecting plates. One end of the spring is fixedly connected to the inner wall of the connecting cavity, and the other end of the spring is fixedly connected to the surface of the connecting shaft.

[0012] In the above technical solution, preferably, the arc-shaped ring has uniformly distributed mounting cavities inside, a sliding plate is slidably connected to the inner wall of the mounting cavity, a driving component is fixedly connected to one end of the sliding plate, and the other end of the driving component is fixedly connected to the inner wall of the mounting cavity. The driving component is a shape memory alloy material component.

[0013] In the above technical solution, preferably, the other end of the slide plate is fixedly connected to a connecting rod, the other end of the connecting rod passes through the mounting cavity and extends into the interior of the connecting cavity, and a mounting shaft is eccentrically fixedly connected to the surface of one of the connecting plates, and a mounting block is rotatably connected to the surface of the mounting shaft, with one end of the mounting block hinged to the end of the connecting rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By incorporating auxiliary components, when the generator's internal temperature rises abnormally, the aluminum arc-shaped ring and heat-conducting strips efficiently absorb heat and conduct it to the shape memory alloy drive component. The drive component expands upon heating, driving a baffle to rotate via a linkage mechanism, automatically opening the air duct and significantly increasing the ventilation area. This design achieves automatic adjustment of heat dissipation efficiency according to temperature changes, enabling timely intervention under high-temperature conditions to enhance heat dissipation and effectively prevent performance degradation or damage to the equipment due to excessive temperature rise. Once the internal temperature of the generator returns to normal, the shape memory alloy drive component cools and contracts, and with the help of the spring, it drives the baffle to automatically reset and close the air duct again, preventing impurities and dust from easily entering the generator due to an excessively large ventilation area. By incorporating a first ventilation slot, a second ventilation slot, and blades linked to the rotating shaft, the generator is ensured to have forced convection cooling capabilities under normal operating conditions. Simultaneously, the filter effectively prevents external dust and debris from entering the generator, ensuring the cleanliness of the core internal components and operational safety.

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1-7 The single-phase and three-phase equal power AC synchronous generator shown includes a generator body 1 and a rotating shaft 104. The rotating shaft 104 is disposed inside the generator body 1, and one end of the rotating shaft 104 extends through the generator body 1. An inner partition 105 is embedded in one side of the generator body 1, and the other end of the rotating shaft 104 extends through the inner partition 105. A single-phase terminal 103 and a three-phase terminal 102 are provided on the surface of the generator body 1. A heat dissipation component 2 is provided at one end of the generator body 1. An auxiliary component 3 is provided on the surface of the generator body 1. A uniformly distributed first ventilation slot 101 is opened on the side of the generator body 1 away from the heat dissipation component 2. A uniformly distributed ventilation hole 106 is opened on the surface of the inner partition 105. The heat dissipation assembly 2 includes a detachable end cap 201 disposed at one end of the generator body 1 and used to cover the inner partition 105. The surface of the end cap 201 is provided with evenly distributed second ventilation slots 202. The inner walls of the first ventilation slot 101 and the second ventilation slot 202 are both fixedly connected with filters.

[0020] Specifically, the rotating shaft 104 is a structure that is integrated into the generator body 1. The generator body 1 includes a rotor core, a rotor excitation winding, a rotating shaft 104, slip rings, an insulating wire frame, a sub-core, a stator winding, a rectifier bridge assembly, carbon brushes, and other structures, which can ensure that the generator body 1 can drive the rotating shaft 104 to rotate when it is in operation. Furthermore, during the operation of the generator body 1, normal air circulation and heat dissipation can be maintained through the first ventilation slot 101 and the second ventilation slot 202. At the same time, the filter screen can prevent external dust and impurities from entering the device and affecting its normal use.

[0021] like Figures 1-7 As shown, an installation plate 203 is fixedly connected to the inner side of the end cap 201. A bearing 204 is embedded in the center of the installation plate 203. One end of the rotating shaft 104 is fixedly connected to the inner wall of the bearing 204. The surface of the installation plate 203 is provided with uniformly distributed through holes 205.

[0022] A mounting ring 206 located between the inner partition 105 and the mounting plate 203 is fixedly connected to the surface of the rotating shaft 104, and uniformly distributed blades 207 are fixedly connected to the surface of the mounting ring 206. Specifically, during the operation of the rotating shaft 104, the mounting ring 206 can drive the blades 207 to rotate, thereby enhancing the air exchange effect and improving the overall heat dissipation effect of the device, providing a good working environment for the generator body 1 during operation.

[0023] like Figures 1-7 As shown, the auxiliary component 3 includes an arc-shaped ring 301 embedded in the surface of the generator body 1. The surface of the arc-shaped ring 301 is provided with uniformly distributed air guide grooves 302, and the inner side of the arc-shaped ring 301 is provided with a groove 304.

[0024] The inner wall of the groove 304 is fixedly connected with uniformly distributed heat-conducting strips 303. Both the arc-shaped ring 301 and the heat-conducting strips 303 are aluminum metal components.

[0025] The arc-shaped ring 301 has evenly distributed connecting cavities 315 inside. The inner wall of the air guide groove 302 is provided with a baffle 305. Both ends of the baffle 305 are fixedly connected to a connecting shaft 306. The other end of the connecting shaft 306 passes through the arc-shaped ring 301 and extends into the interior of the connecting cavity 315.

[0026] Two symmetrically distributed connecting plates 307 are fixedly connected to the surface of the connecting shaft 306. The connecting plates 307 are rotatably connected to the inner wall of the connecting cavity 315. A spring 308 is provided between the two connecting plates 307. One end of the spring 308 is fixedly connected to the inner wall of the connecting cavity 315, and the other end of the spring 308 is fixedly connected to the surface of the connecting shaft 306.

[0027] The arc-shaped ring 301 has uniformly distributed mounting cavities 309 inside. A sliding plate 313 is slidably connected to the inner wall of the mounting cavity 309. A driving component 310 is fixedly connected to one end of the sliding plate 313. The other end of the driving component 310 is fixedly connected to the inner wall of the mounting cavity 309. The driving component 310 is a shape memory alloy material component.

[0028] The other end of the slide plate 313 is fixedly connected to a connecting rod 311. The other end of the connecting rod 311 passes through the mounting cavity 309 and extends into the interior of the connecting cavity 315. An mounting shaft 314 is eccentrically fixedly connected to the surface of one of the connecting plates 307. A mounting block 312 is rotatably connected to the surface of the mounting shaft 314. One end of the mounting block 312 is hinged to the end of the connecting rod 311.

[0029] Specifically, when the generator body 1 experiences excessively high temperatures during operation, preventing timely cooling through normal heat dissipation, the hot airflow generated during normal heat dissipation can heat the arc-shaped ring 301 via the heat-conducting strip 303. Both the heat-conducting strip 303 and the arc-shaped ring 301 are made of aluminum, providing excellent heat conduction. Furthermore, the design of the heat-conducting strip 303 and the groove 304 enhances heat absorption and increases the heat absorption area. As the temperature rises, it heats the drive component 310 formed from the shape memory alloy material. The heated drive component 310 extends, pushing the sliding plate 313 along the inner wall of the mounting cavity 309. During this process, it moves the connecting rod 311, which in turn moves the mounting shaft 314 through the hinged connection between the mounting block 312 and the connecting rod 311. Due to the eccentric setting of the mounting shaft 314 and the connecting plate 307, and the rotatable connection between the mounting block 312 and the mounting shaft 314… The configuration allows the connecting rod 311 to move, causing the connecting plate 307 to rotate. The rotation of the connecting plate 307 synchronously drives the connecting shaft 306 to rotate. Since one end of the spring 308 is connected to the connecting shaft 306 and the other end is fixedly connected to the inner wall of the connecting cavity 315, the connecting shaft 306 rotates and winds up from the center of the spring 308 (the connecting plate 307 restricts the position of the spring 308, and the two connecting plates 307 rotate synchronously during the rotation of the connecting shaft 306; the spring 308 is mainly wound up by the connecting shaft 306). Simultaneously, the baffle 305 is tilted, preventing it from obstructing the air guide slot 302, increasing the ventilation area during the heat dissipation process of the blades 207, and thus enhancing the heat dissipation effect. This continues until the internal temperature of the generator body 1 drops, and the drive component 310 cools down and resets in conjunction with the reset effect of the spring 308. Furthermore, the drive component 310 is a NiTi shape memory alloy.

[0030] Working Principle: During the operation of the generator body 1, air circulation and normal heat dissipation are maintained through the first ventilation slot 101 and the second ventilation slot 202. Simultaneously, the filter screen prevents external dust and impurities from entering the device and affecting its normal operation. When the generator body 1 experiences excessively high temperatures during operation, preventing timely cooling, the hot airflow generated during normal heat dissipation can heat the arc-shaped ring 301 through the heat-conducting strip 303. Both the heat-conducting strip 303 and the arc-shaped ring 301 are made of aluminum, providing excellent heat conduction. Furthermore, the design of the heat-conducting strip 303 and the groove 304 better absorbs heat and increases the heat absorption area. As the temperature rises, the drive component 310, formed from the shape memory alloy material, is heated. The heated drive component 310 can then extend and push... The sliding plate 313 slides along the inner wall of the mounting cavity 309, which in turn drives the connecting rod 311 to move. In turn, the mounting shaft 314 can be moved under the hinged operation of the mounting block 312 and the connecting rod 311. Due to the eccentric setting of the mounting shaft 314 and the connecting plate 307 and the rotational connection of the mounting block 312 and the mounting shaft 314, the connecting plate 307 can be rotated during the movement of the connecting rod 311, which in turn drives the connecting shaft 306 to rotate and tightens the spring 308 in the process. At the same time, the baffle 305 is tilted so that the baffle 305 no longer blocks the air guide slot 302, increasing the ventilation area during the heat dissipation process of the blade 207, thereby enhancing the heat dissipation effect. Until the internal temperature of the generator body 1 drops, the drive component 310 cools down and resets in conjunction with the reset effect of the spring 308.
