Description

Technical Field

[0001] This utility model relates to the field of rectifiers, specifically a fastened rotary rectifier. Background Technology

[0002] A rotating rectifier is a device that converts alternating current (AC) to direct current (DC) and is widely used in generator excitation systems. It precisely adjusts the magnitude and polarity of the excitation current by controlling the switching state, thereby controlling the generator's magnetic field. Rotating rectifiers are characterized by high flexibility, fast response, and low energy consumption, with low maintenance costs, and can adapt to excitation requirements under different load conditions. Furthermore, the brushless design of the rotating rectifier eliminates the need for sliding contact devices such as slip rings and brushes, improving system reliability.

[0003] When in use, the rotary rectifier is usually installed on the exciter rotor, which means that there are no protective devices on it. This means that the rotary rectifier does not have waterproof or other functions. Once water gets in, it may be damaged and become inoperable.

[0004] Therefore, a clamping rotary rectifier is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problem that rotating rectifiers are generally installed on the exciter rotor during use, which means they lack protective devices and therefore do not have waterproofing capabilities, making them susceptible to damage and malfunction if water gets in. This invention proposes a fastening-type rotating rectifier.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a fastening type rotary rectifier, including a rotary rectifier, a second screw hole is provided inside the rotary rectifier, a protective component is provided on the outside of the rotary rectifier, the protective component includes a placement frame slidably connected to the outside of the rotary rectifier, a cover frame is slidably connected to the outside of the placement frame, a sleeve ring is fixedly connected to the outside of both the placement frame and the cover frame, a first screw hole is provided inside both the placement frame and the cover frame, an installation ring is fixedly connected to the outside of the placement frame, and two closing rings are fixedly connected to the outside of the installation ring.

[0007] Preferably, an insertion component is provided on the outside of the placement frame. The insertion component includes a stabilizing ring slidably connected to the outside of the placement frame, and an insertion rod is rotatably connected to the outside of the stabilizing ring. The insertion rod passes through the mounting ring and is slidably connected.

[0008] Preferably, the insertion rod is provided with a limiting component, which includes two limiting rods fixedly connected inside the insertion rod, a limiting plate fixedly connected to the end of the limiting rod, a connecting plate slidably connected to the outside of the limiting rod, and a spring fixedly connected between the connecting plate and the insertion rod.

[0009] Preferably, the limiting assembly further includes two connecting rods fixedly connected to the outside of the connecting plate, a limiting plate fixedly connected to the end of the connecting rod, the limiting plate being slidably connected to the inside of the insertion rod, and an insertion block fixedly connected to the outside of the limiting plate, the insertion block penetrating the insertion rod and being slidably connected.

[0010] Preferably, a rotating assembly is provided on the outer side of the insertion rod. The rotating assembly includes a gear fixedly connected to the outer side of the insertion rod, a gear ring meshing with the outer side of the gear, and the inner side of the gear ring slidingly connected to the outer side of the placement frame.

This reduces the possibility of problems with the rotary rectifier and ensures its normal use.

[0016] 2. This utility model rotates the handle, which drives the placement ring to rotate, which in turn drives the gear ring to rotate, which in turn drives the gear to rotate, which in turn drives the insertion rod to rotate, which in turn drives the insertion block to move, allowing the insertion block to enter the insertion rod.

[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

[0027] Please see Figure 1-6As shown, a fastening type rotary rectifier includes a rotary rectifier 1, with a second screw hole 11 inside the rotary rectifier 1. A protective component is provided on the outside of the rotary rectifier 1. The protective component includes a placement frame 2 slidably connected to the outside of the rotary rectifier 1, a cover frame 3 slidably connected to the outside of the placement frame 2, and a sleeve ring 4 fixedly connected to the outside of both the placement frame 2 and the cover frame 3. A first screw hole 5 is provided inside both the placement frame 2 and the cover frame 3. An installation ring 6 is fixedly connected to the outside of the placement frame 2, and two closing rings 7 are fixedly connected to the outside of the installation ring 6.

[0028] During operation, the rotary rectifier 1 is placed inside the placement frame 2, and then the cover frame 3 is placed outside the placement frame 2. The positions of the placement frame 2 and the cover frame 3 are then fixed by the cooperation of the insertion component and the limiting component, so that the closing ring 7 abuts and squeezes against the cover frame 3, thereby sealing off the space inside the placement frame 2 and the cover frame 3 to a certain extent. This protects the rotary rectifier 1 and reduces the possibility of water vapor affecting the rotary rectifier 1, thereby reducing the possibility of problems with the rotary rectifier 1 and ensuring its normal use.

[0029] The placement frame 2 is provided with an insertion component on its outer side. The insertion component includes a stabilizing ring 8 that is slidably connected to the outer side of the placement frame 2. An insertion rod 9 is rotatably connected to the outer side of the stabilizing ring 8. The insertion rod 9 passes through the mounting ring 6 and is slidably connected.

[0030] During operation, the stabilizing ring 8 is pushed to insert the insertion rod 9 into the cover frame 3, and then the positions of the stabilizing ring 8 and the insertion rod 9 are fixed by the limiting component.

[0031] The insertion rod 9 is equipped with a limiting component, which includes two limiting rods 10 fixedly connected inside the insertion rod 9. A limiting plate 13 is fixedly connected to the end of the limiting rod 10. A connecting plate 12 is slidably connected to the outside of the limiting rod 10. A spring 14 is fixedly connected between the connecting plate 12 and the insertion rod 9.

[0032] The limiting assembly also includes two connecting rods 15 fixedly connected to the outside of the connecting plate 12. The end of the connecting rod 15 is fixedly connected to a limiting plate 16. The limiting plate 16 is slidably connected to the inside of the insertion rod 9. An insertion block 17 is fixedly connected to the outside of the limiting plate 16. The insertion block 17 passes through the insertion rod 9 and is slidably connected.

[0033] During operation, by rotating the insertion rod 9, the insertion block 17 is moved, thereby allowing the insertion block 17 to enter the insertion rod 9. At the same time, the connecting rod 15 is moved, thereby causing the connecting plate 12 to slide outside the limiting rod 10, thereby compressing the spring 14, so that the insertion block 17 can smoothly enter the insertion rod 9, and thus the position of the insertion rod 9 can be changed.

[0034] When it is necessary to further restrict the position of the insertion rod 9, the connecting plate 12 can be pushed by the spring 14, thereby moving the connecting plate 12 and the connecting rod 15, thereby moving the insertion block 17 to the outside of the insertion rod 9, and cooperating with the slot inside the cover frame 3 to restrict the position of the insertion block 17, thus restricting the position of the insertion rod 9.

[0035] The cover frame 3 has the same size as the mounting ring 6, and the inside of the cover frame 3 is penetrated and slidably connected by the insert block 17.

[0036] During operation, the position of the insertion rod 9 can be restricted by the cooperation between the insertion block 17 and the cover frame 3.

[0037] Example 2

[0038] Please see Figure 4 As shown in the first embodiment, as another implementation of this utility model, a rotating assembly is provided on the outside of the insertion rod 9. The rotating assembly includes a gear 18 fixedly connected to the outside of the insertion rod 9. A gear ring 19 meshes with the outside of the gear 18. The inside of the gear ring 19 is slidably connected to the outside of the placement frame 2.

[0039] The rotating assembly also includes a placement ring 20 fixedly connected to the outside of the gear ring 19. Two handles 21 are fixedly connected to the outside of the placement ring 20. A baffle 22 is abutted against the outside of the placement ring 20. The baffle 22 is fixedly connected to the outside of the placement frame 2.

[0040] During operation, rotating the handle 21 causes the placement ring 20 to rotate, which in turn causes the gear ring 19 to rotate, which in turn causes the gear 18 to rotate, which in turn causes the insertion rod 9 to rotate, thereby causing the insertion block 17 to move and enter the insertion rod 9. Then, pulling the handle 21 causes the placement ring 20 to move, which in turn causes the gear ring 19 to move, and at the same time causes the stabilizing ring 8 and the insertion rod 9 to move, thereby separating the insertion rod 9 from the cover frame 3, thus allowing the device to be disassembled, thereby improving the efficiency of disassembly.

[0041] The placement ring 20 is slidably connected to the outside of the stabilizing ring 8, and the placement ring 20 is slidably connected to the outside of the placement frame 2.

[0042] During operation, the movement of the placement ring 20 can drive the movement of the stabilizing ring 8. The stabilizing ring 8 is rotated inside the placement ring 20, thus ensuring that the stabilizing ring 8 does not affect the rotation of the placement ring 20.

[0043] The working principle is as follows: the rotary rectifier 1 is placed inside the placement frame 2, and then the cover frame 3 is placed outside the placement frame 2. The stabilizing ring 8 is then pushed to insert the insertion rod 9 into the cover frame 3. A spring 14 then pushes the connecting plate 12, causing the connecting plate 12 and the connecting rod 15 to move. This moves the insertion block 17 to the outside of the insertion rod 9, which, in conjunction with the slot inside the cover frame 3, restricts the position of the insertion block 17. This restricts the position of the insertion rod 9, thus fixing the positions of the placement frame 2 and the cover frame 3. The closing ring 7 then abuts and presses against the cover frame 3, effectively sealing the space inside the placement frame 2 and the cover frame 3. This protects the rotary rectifier 1, reducing the possibility of water affecting it and minimizing the likelihood of problems, thus ensuring its normal operation.
