[0031] Example
[0032] like Figures 1 to 4 As shown, the present invention proposes a transformer vibration damping and fixing device, including a fixed plate 1, the position of which is fixed and the fixing plate 1 is installed and fixed by bolts. The transformer body is disposed on the side of the fixing plate 1.
[0033] Specifically, the aforementioned fixing device includes two sets of first buffer components 2. The first buffer components 2 are installed on the side of the fixing plate 1, and a buffer plate 3 is installed on the side of the first buffer components 2 away from the fixing plate 1. The first buffer components 2 are used to buffer the lateral vibration of the buffer plate 3 during an earthquake. The first buffer components 2 include a first damping block 21 fixedly connected to the side of the fixing plate 1, and the position of the first damping block 21 is fixed. A first sliding rod 22 is slidably connected to the first damping block 21, and a first buffer frame 23 is fixedly connected to the first sliding rod 22. The first sliding rod 22 and the first buffer frame 23 move synchronously. The first buffer frame 23 is U-shaped and fixedly connected to the buffer plate 3. When the buffer plate 3 moves, it drives the first buffer frame 23 to move synchronously. Both sides of the first damping block 21 are provided with a first spring 24. The first spring 24 is sleeved on the outer ring of the first slide rod 22. When the first buffer frame 23 vibrates left and right with the buffer plate 3 during an earthquake, it slides on the first slide rod 22 through the first damping block 21 and squeezes the first spring 24 to buffer. At the same time, the large friction between the first damping block 21 and the first slide rod 22 prevents the first spring 24 from reciprocating.
[0034] Furthermore, the aforementioned fixing device also includes at least two sets of second buffer components 4 installed on the side of the buffer plate 3 away from the fixing plate 1. A mounting frame 5 is installed on the side of the second buffer component 4 away from the buffer plate 3. The second buffer component 4 is used to buffer the vertical vibration generated by the mounting frame 5 during an earthquake. The mounting frame 5 has a "U"-shaped structure. The second buffer component 4 includes a second damping block 41 fixedly connected to the side of the buffer plate 3 away from the fixing plate 1. A second sliding rod 42 is slidably connected to the second damping block 41. A second buffer frame 43 is fixedly connected to the second sliding rod 42. The second buffer frame 43 has a "U"-shaped arrangement and is fixedly connected to the mounting frame 5. When the mounting frame 5 moves, it drives the second buffer frame 43 to move synchronously. The second damping block 41 is provided with a second spring 44 on both sides. The second spring 44 is sleeved on the outer ring of the second slide rod 42. The second buffer frame 43 vibrates up and down with the mounting frame 5 during an earthquake. At the same time, the second buffer frame 43 drives the second spring 44 to squeeze the vibration and buffer the vibration. Meanwhile, the large friction between the second slide rod 42 and the second damping block 41 prevents the second spring 44 from reciprocating.
[0035] Furthermore, the aforementioned fixing device includes two sets of third buffer components 6 disposed inside the mounting frame 5. These third buffer components 6 are used to buffer the forward and backward vibrations of the transformer body during an earthquake. Each third buffer component 6 includes a third buffer frame 61 fixedly connected inside the mounting frame 5. The third buffer frame 61 is U-shaped, and a third slide rod 62 is fixedly connected within it. A third damping block 63 is slidably connected to the third slide rod 62. Third springs 64 are disposed on both sides of the third damping block 63, and are fitted onto the outer ring of the third slide rod 62. During an earthquake, the transformer body causes the third damping block 63 to vibrate forward and backward and slide on the third slide rod 62, simultaneously compressing the third springs 64 for buffering. The significant friction between the third slide rod 62 and the third damping block 63 prevents the third springs 64 from reciprocating.
[0036] Finally, a clamping mechanism 7 is installed on the side of the third buffer assembly 6 away from the mounting frame 5 in the aforementioned fixing device. The clamping mechanism 7 is used to clamp and fix the transformer body. The clamping mechanism 7 includes a mounting plate 71 fixedly connected to the side of the third damping block 63 away from the mounting frame 5. A fixing block 72 is fixedly connected to the side of the mounting plate 71 away from the third damping block 63. Two sets of limiting rods 73 are fixedly connected to the side of the fixing block 72 away from the fixing plate 1. A moving block 74 is slidably connected between the two sets of limiting rods 73, so that when the moving block 74 approaches the fixing block 72, it can move smoothly under the limiting action of the limiting rods 73. A bolt 75 is provided through the moving block 74, and the bolt 75 is threadedly connected to the fixing block 72, fixing the moving block 74 to the side of the fixing block 72 through the bolt 75. Both the fixing block 72 and the moving block 74 are L-shaped. A rubber pad 76 is provided on the side of the fixing block 72 and the moving block 74 that contacts the transformer body to increase friction and improve the stability after the fixing block 72 and the moving block 74 clamp the transformer body.
[0037] In this embodiment, when installing the transformer body, the transformer body is placed between the upper and lower fixed blocks 72. Then, the movable block 74 is locked between the two sets of limiting rods 73, and the bolt 75 is threaded through the movable block 74 and connected to the fixed block 72. After tightening the bolt 75, the movable block 74 and the fixed block 72 press against the transformer body, thus fixing the transformer body. During an earthquake, when the first buffer frame 23 vibrates left and right with the buffer plate 3, it is buffered by the first damping block 21 sliding on the first slide rod 22 and compressing the first spring 24. At the same time, the large friction between the first damping block 21 and the first slide rod 22 prevents the first spring 24 from reciprocating. The second buffer frame 43 vibrates up and down with the mounting frame 5, and at the same time, the second buffer frame 43 compresses the second spring 44 to buffer the vibration. At the same time, the large friction between the second slide rod 42 and the second damping block 41 prevents the second spring 44 from reciprocating. Simultaneously, the third damping block 63 vibrates back and forth and slides on the third slide rod 62, compressing the third spring 64 for buffering. The significant friction between the third slide rod 62 and the third damping block 63 prevents the third spring 64 from reciprocating. This buffering of earthquake vibrations in different directions effectively prevents damage to the first buffer assembly 2 and ensures the stability of the power supply.
[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
