Technical Field

[0001] This utility model relates to the field of generator base technology, specifically a base structure for a three-phase AC synchronous generator. Background Technology

[0002] Three-phase AC synchronous generators require a base for support during use. This base provides sufficient strength and rigidity to support the generator's weight and dynamic loads during operation, offers good vibration damping to reduce vibration transmission, and is corrosion resistant to adapt to different environments.

[0003] The base structure of such three-phase AC synchronous generators on the market today is used by placing the base frame on the ground, installing the three-phase AC synchronous generator on the base frame through bidirectional telescopic crossbars and locking threaded grooves, and then connecting to the power supply through the power cord. When moving the three-phase AC synchronous generator, the base frame is moved to the transfer equipment. This requires a transfer device to follow the generator when it is in use, which increases the operation and maintenance costs of the three-phase AC synchronous generator equipment deployment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1-5As shown, a base structure for a three-phase AC synchronous generator includes a base frame 1, a support part 2, a connecting part 4, a sliding part 3, and a side plate 13. The base frame 1 is used for mounting to the bottom of the three-phase AC synchronous generator. During use, the bottom of the base frame 1 will be flush with the ground, reducing the gap between the base frame 1 and the ground. The support part 2 is rotatably disposed on both sides of the base frame 1 to support the movable base frame 1. Part of the connecting part 4 is inserted into the base frame 1, and the connecting part 4 is disposed on both sides of the support part 2 to connect the base frame 1 and the support part 2. The support part 2 provides support; the sliding part 3 is disposed inside the base frame 1 and is used to connect the connecting part 4 and the base frame 1. The sliding part 3 and the connecting part 4 are rotatably connected. Side plates 13 are connected to the surfaces of the base frame 1 on both sides of the sliding part 3 to limit the support part 2 and prevent the support part 2 from rotating when it is in contact with the base frame 1. At the same time, the gap between the side plates 13 is used to place the connecting part 4 to prevent the connecting part 4 from directly contacting the ground and further protect the side of the connecting part 4. The support part 2 rotates around the part where the connecting part 4 and the sliding part 3 are connected.

[0027] The overall effect of this embodiment is that, during use, the bottom of the base frame 1 is placed against the ground to reduce the gap between the base frame 1 and the ground. A three-phase AC synchronous generator is then detachably connected to the base frame 1 for external power supply. When it is necessary to move the base frame 1 and the three-phase AC synchronous generator, the support part 2 is rotated. The support part 2 will rotate under the action of the connecting part 4 and the sliding part 3, turning to... Figure 2 At the location, the base frame 1 and the three-phase AC synchronous generator are moved.

[0028] Example 2: Figure 1-5 As shown, a base structure for a three-phase AC synchronous generator includes a support part 2 with a connecting plate 21 connected to the end of a connecting part 4. The connecting plate 21 is a retractable straight plate design, with a minimum length greater than or equal to the length of the base frame 1 and a width less than or equal to the base frame 1. Two pulleys 22 are rotatably connected to the side of the connecting plate 21 away from the base frame 1 for moving the base frame 1. To facilitate the operator's rotation of the connecting plate 21, a groove 23 is provided on the side of the connecting plate 21 located on the base frame 1. The pulleys 22 are symmetrically distributed along the center line of the connecting plate 21, and the top of the groove 23 penetrates through the top of the connecting plate 21.

[0029] To facilitate the rotational support of the connecting plate 21, the connecting part 4 includes two connecting rods 41 connected to the connecting plate 21 on both sides of the base frame 1. These connecting rods 41 are symmetrically distributed along the centerline of the connecting plate 21. Figure 5 As shown, the cross-section of the connecting rod 41 is designed in an "L" shape, and the connecting rod 41 is used to support the connecting plate 21.

[0030] The connecting part 4 also includes an inner rod 43 inserted into the sliding part 3. The inner rod 43 is circular and its diameter is smaller than the four sides of the part connected to the connecting rod 41. The end of the inner rod 43 away from the sliding part 3 is connected to the side of the connecting rod 41, and part of the connecting rod 41 is inserted into the sliding part 3.

[0031] The sliding part 3 includes a first groove 31, a second groove 32, and a limiting member 33. The second groove 32 is located at the end of the first groove 31 near the support part 2. The second groove 32 and the first groove 31 are connected to each other, allowing some of the connecting rods 41 to slide within the second groove 32 and the first groove 31. The longitudinal length of the second groove 32 is greater than the longitudinal length of the first groove 31, and the transverse length of the second groove 32 is the same as the transverse length of the first groove 31. The first groove 31 and the second groove 32 are slidably connected to the connecting rods 41. The length of the connecting rods 41 inserted into the first groove 31 and the second groove 32 is greater than the depth of the first groove 31 and the second groove 32. The distance between the two farthest connecting rods 41 is greater than the length of the base frame 1, and the distance between the connecting rods 41 connected to the inner rod 43 is less than the length of the base frame 1.

[0032] The limiting member 33 includes a connecting block 332 that is slidably inserted into the first segment groove 31 and the second segment groove 32. The first segment groove 31 and the second segment groove 32 have a limiting groove that is inserted into the connecting block 332. The limiting groove is used to limit the connecting block 332 and prevent the connecting block 332 from separating from the first segment groove 31 and the second segment groove 32. The lateral side length of the connecting block 332 is greater than the lateral width of the second segment groove 32.

[0033] The connecting block 332 is located inside the first section groove 31 and the second section groove 32 and is connected to the sliding block 331. The side length of the sliding block 331 is smaller than the lateral width of the second section groove 32. When the connecting rod 41 and the inner rod 43 reach the position of the second section groove 32, the midpoint of the limiting member 33 will coincide with the center of the second section groove 32. The side of the sliding block 331 away from the connecting block 332 abuts against the inner rod 43. The side length of the sliding block 331 is larger than the diameter of the inner rod 43.

[0034] A connecting spring 42 is sleeved on the surface of the inner rod 43. One end of the connecting spring 42 is connected to the side of the connecting rod 41, and the other end of the connecting spring 42 is connected to the side of the connecting block 332. The connection method between the connecting spring 42, the connecting rod 41, and the sliding block 331 is the existing connection method, such as plug-in or hook-in. When there is no external force, the connecting spring 42 will pull the two connecting rods 41 into the first groove 31 or the second groove 32. After being subjected to force, it can increase the distance between the two connection points, thereby limiting the connection rod 41.

[0035] The groove 23 and connecting rod 41 mentioned above should be made of high-hardness metal materials to avoid deformation of the connecting plate 21 due to load during use.

[0036] The effect achieved by the entire second embodiment is that when the connecting plate 21 and the side of the base frame 1 are in contact, the connecting rod 41... Figure 1 and Figure 5 As shown, the portion of connecting rod 41 that connects to inner rod 43 is slidably inserted into a first-section groove 31. Pulling the groove 23 causes the connecting plate 21 to slide the connecting rod 41 within the first-section groove 31. When the portion of connecting rod 41 that connects to inner rod 43 reaches the second-section groove 32, pulling the connecting plate 21 causes the connecting rod 41 to slide from the first-section groove 31 to the second-section groove 32 under the action of the connecting spring 42. Pulling the connecting plate 21 to both sides increases the distance between the two connecting rods 41, causing the connecting rod 41 to separate from the second-section groove 32. Then, rotating the connecting plate 21 around the center point of inner rod 43... Figure 2 At this position, the part of the connecting rod 41 that connects to the inner rod 43 will align with the second-stage groove 32. Loosening the connecting plate 21 will cause the connecting plate 21 to, under the action of the connecting spring 42, hold the connecting rod 41 in place. Figure 2 The vertical insertion is shown in the second-section slot 32. Since the horizontal length of the second-section slot 32 is the same as the horizontal length of the first-section slot 31, the first-section slot 31 and the second-section slot 32 are slidably connected to the connecting rod 41. At this time, the connecting rod 41 is confined within the second-section slot 32. The base frame 1 can then be pulled, causing it to shift. After the shift is complete, the base frame 1 will... Figure 2 The support part 2 is reset to Figure 1 The pull-out support 2 allows the bottom of the base frame 1 to be in contact with the ground when the three-phase AC synchronous generator at the top of the base frame 1 is in operation, reducing the distance between the base frame 1 and the ground and avoiding excessive shaking caused by an excessive distance between the base frame 1 and the ground.

[0037] Example 3: Figure 1-5 As shown, a base structure for a three-phase AC synchronous generator is provided. The top of the base frame 1 is connected to two bidirectional telescopic crossbars 12. In order to reduce the vibration between the bidirectional telescopic crossbars 12 and the base frame 1, the bidirectional telescopic crossbars 12 and the base frame 1 are connected by welding. The bidirectional telescopic crossbars 12 are provided with locking thread grooves 11 inside. The locking thread grooves 11 are used to connect the three-phase AC synchronous generator, the bidirectional telescopic crossbars 12, and the base frame 1 with bolts.

[0038] The effect achieved by the entire embodiment three is that, in use, the three-phase AC synchronous generator is placed on the bidirectional telescopic crossbar 12, and the threaded groove and locking threaded groove 11 at the bottom of the three-phase AC synchronous generator are aligned. Then, the three-phase AC synchronous generator, the bidirectional telescopic crossbar 12, and the base frame 1 are connected by bolts to complete the installation of the three-phase AC synchronous generator and the base frame 1.

[0039] Working Principle: When using the base structure for this three-phase AC synchronous generator, first, check that all components are in good working order. Place the bottom of the base frame 1 against the ground to reduce the gap between the base frame 1 and the ground. Then, place the three-phase AC synchronous generator on the bidirectional telescopic crossbar 12, aligning the threaded grooves on the bottom of the three-phase AC synchronous generator with the locking threaded grooves 11. Finally, connect the three-phase AC synchronous generator, bidirectional telescopic crossbar 12, and base frame 1 using bolts to complete the installation of the three-phase AC synchronous generator and base frame 1. It is then used with an external power supply. When it is necessary to move the base frame 1 and the three-phase AC synchronous generator, rotate the support part 2. The support part 2 will rotate under the action of the connecting part 4 and the sliding part 3, turning to... Figure 2 At the location, the base frame 1 and the three-phase AC synchronous generator are moved;

[0040] Secondly, when the connecting plate 21 and the side of the base frame 1 are attached, the connecting rod 41, as Figure 1 and Figure 5 As shown, the portion of connecting rod 41 that connects to inner rod 43 is slidably inserted into a first-section groove 31. Pulling the groove 23 causes the connecting plate 21 to slide the connecting rod 41 within the first-section groove 31. When the portion of connecting rod 41 that connects to inner rod 43 reaches the second-section groove 32, pulling the connecting plate 21 causes the connecting rod 41 to slide from the first-section groove 31 to the second-section groove 32 under the action of the connecting spring 42. Pulling the connecting plate 21 to both sides increases the distance between the two connecting rods 41, causing the connecting rod 41 to separate from the second-section groove 32. Then, rotating the connecting plate 21 around the center point of inner rod 43... Figure 2 At this position, the part of the connecting rod 41 that connects to the inner rod 43 will align with the second-stage groove 32. Loosening the connecting plate 21 will cause the connecting plate 21 to, under the action of the connecting spring 42, hold the connecting rod 41 in place. Figure 2 The vertical insertion is shown in the second-section slot 32. Since the horizontal length of the second-section slot 32 is the same as the horizontal length of the first-section slot 31, the first-section slot 31 and the second-section slot 32 are slidably connected to the connecting rod 41. At this time, the connecting rod 41 is confined within the second-section slot 32. The base frame 1 can then be pulled, causing it to shift. After the shift is complete, the base frame 1 will... Figure 2 The support part 2 is reset to Figure 1 The pull-out support 2 allows the bottom of the base frame 1 to be in contact with the ground when the three-phase AC synchronous generator at the top of the base frame 1 is in operation, reducing the distance between the base frame 1 and the ground. This prevents excessive shaking caused by an excessive distance between the base frame 1 and the ground, thus completing the work of the base structure for the three-phase AC synchronous generator.
