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.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a vibration isolation device for battery packs in electrochemical energy storage power stations, including a base plate 1, a battery pack base 4 above the base plate 1, multiple support blocks 3 fixedly installed below the base plate 1, and anti-slip rubber pads 2 fixedly installed below the support blocks 3. The base plate 1 and the battery pack base 4 are connected by a vibration damping connection device 5, and auxiliary fixing devices 6 are fixedly installed on both sides of the base plate 1.

[0022] Specifically, the vibration damping connection device 5 includes a support box 51, a bidirectional lead screw 52, ​​a clamping sleeve 53, a movable frame 54, an elastic rubber frame 55, a damper 56, and a rotating assembly 57. An elastic rubber frame 55 is fixedly connected above the base plate 1 and below the battery pack base 4. Multiple dampers 56 are fixedly connected above the base plate 1 and inside the elastic rubber frame 55. A support box 51 is provided between the base plate 1 and the elastic rubber frame 55. A bidirectional lead screw 52 is installed near the center of the support box 51 via a bearing. Two movable frames 54 are threaded onto the outer side of the bidirectional lead screw 52. Clamping sleeves 53 are fixedly installed on both sides of the battery pack base 4 and on the outer top of the movable frames 54. The support box 51 is connected to the elastic rubber frame 55 and the multiple dampers 56 via the rotating assembly 57.

[0023] By adopting the above technical solution, the device can buffer and isolate external vibrations through the elastic rubber frame 55 and the damper 56, thereby ensuring the vibration isolation effect. When needed, the staff can connect the device to the battery pack through the cooperation of structures such as the movable frame 54 and the clamp 53.

[0024] Specifically, the height of the inner bottom surface of the support box 51 is equal to the height of the outer bottom surface of the movable frame 54.

[0025] By adopting the above technical solution, the device can ensure that the inner bottom surface of the support box 51 and the outer bottom surface of the movable frame 54 are in close contact with each other, thereby preventing the movable frame 54 from rotating or shifting during movement and ensuring normal operation.

[0026] Specifically, the rotating assembly 57 includes a rotating shaft 571, a support frame 572, a rotating plate 573, and a tightening screw 574. The support frame 572 is fixedly installed above the elastic rubber frame 55 and multiple dampers 56 and below the support box 51. The rotating shaft 571 is fixedly installed below the support box 51 and inside the support frame 572. The rotating plate 573 is fixedly installed outside the rotating shaft 571 and inside the support frame 572. Tightening screws 574 are threadedly installed on both sides of the support frame 572 near the edge.

[0027] By adopting the above technical solution, staff can adjust the direction of the battery pack by using the combination of structures such as the rotating shaft 571 and the rotating plate 573 when needed, thereby better meeting the work needs in different situations.

[0028] In this embodiment, when the battery pack of the electrochemical energy storage power station needs to be vibrated using the device, the battery pack base 4 is a structure fixed under the battery pack. The operator places the battery pack and its base 4 above the support box 51 in the vibration damping connection device 5, and then rotates the bidirectional lead screw 52. The bidirectional lead screw 52 is threadedly connected to the two movable frames 54, and the inner bottom surface of the support box 51 is in contact with the outer bottom surface of the two movable frames 54. Therefore, the bidirectional lead screw 52 drives the two movable frames 54 to move until the two movable frames 54 are inserted into the two retaining sleeves 53, thereby fixing the battery pack base 4 and the battery pack on it. Position the battery pack 57, then tighten the two locking screws 574 in the rotating assembly 57 to release the rotating plate 573. Then pull the support box 51 to make it rotate with the battery pack and rotating shaft 571. The rotating shaft 571 is connected to the support frame 572 by a bearing. When the battery pack rotates to the required direction, turn the two locking screws 574 in the opposite direction to tighten the rotating plate 573, thereby preventing the rotating plate 573 and other structures from rotating. Then, the elastic rubber frame 55 and damper 56 between the base plate 1 and the support frame 572 buffer external vibrations, thereby performing vibration isolation. The support block 3 plays a supporting role, and the anti-slip rubber pad 2 plays an anti-slip role.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the auxiliary fixing device 6 includes a connecting box 61, a rotating screw 62, a lifting block 63, and suction cups 64. The connecting box 61 is fixedly installed on both sides of the base plate 1. The rotating screw 62 is installed near the center of the connecting box 61 through a bearing. The lifting block 63 is installed on the outside of the rotating screw 62 and on the inside of the connecting box 61 through a thread. Multiple suction cups 64 are fixedly installed below the lifting block 63.

[0031] By adopting the above technical solution, staff can use the suction cup 64 and lifting block 63 to fix the device position when needed, thereby reducing the possibility of the device moving accidentally due to collisions or other reasons.

[0032] Specifically, the shape and size of the inner cross-section of the connecting box 61 are the same as the shape and size of the outer cross-section of the lifting block 63.

[0033] By adopting the above technical solution, the device can ensure that the inner side of the connecting box 61 and the outer side of the lifting block 63 fit together, thereby preventing the lifting block 63 from rotating or shifting during movement and ensuring normal operation.

[0034] In this embodiment, when it is necessary to assist in fixing the position of the device, the operator rotates the rotating screws 62 in the two auxiliary fixing devices 6 respectively. The rotating screws 62 are threadedly connected to the lifting blocks 63, and the outer side of the lifting blocks 63 is in contact with the inner side of the connecting box 61. Therefore, the two rotating screws 62 drive the two lifting blocks 63 and the suction cups 64 below them to descend until the suction cups 64 are attached to the floor, thereby assisting in fixing the position of the device, reducing the possibility of the device moving accidentally due to collisions or other reasons, and ensuring the normal operation of the work.

[0035] The structure and principle of the damper 56, which consists of a cylinder, piston rod, piston, first pressure plate, second pressure plate, damping shaft, viscous fluid, first hollow screw, second hollow screw, pressure block, spring, first outer hole, first inner hole, second outer hole, second inner hole, pressure-bearing middle part, first pressure-bearing end, second pressure-bearing end, first guide part, second guide part, shaft body, direct flow channel, first head and second head, have been disclosed in the speed-adjustable damper disclosed in Chinese patent application number 202121081254.2. Its working principle is that a uniform speed shaft is set on the piston to achieve a stable damping effect, and a variable speed shaft is set on the piston, and the cross-sectional area of ​​the variable speed channel is set to be inversely proportional to the pressure value, so that when the pressure increases, the cross-sectional area of ​​the variable speed channel is smaller, the viscous fluid is more difficult to flow, and ultimately the damping effect is better.

[0036] The working principle and usage process of this utility model are as follows: When the battery pack of an electrochemical energy storage power station needs to be vibrated using the device, the battery pack base 4 is a structure fixed under the battery pack. The operator places the battery pack and its base 4 above the support box 51 in the vibration damping connection device 5. Then, the double-acting screw 52 is rotated. The double-acting screw 52 is threadedly connected to two movable frames 54, and the inner bottom surface of the support box 51 is in contact with the outer bottom surface of the two movable frames 54. Therefore, the double-acting screw 52 drives the two movable frames 54 to move until the two movable frames 54 are inserted into the two retaining sleeves 53, thereby fixing the position of the battery pack base 4 and the battery pack on it. Then, the two tightening screws 574 in the rotating assembly 57 are turned to release the rotating plate 573. Then, the support box 51 is pulled to rotate with the battery pack and the rotating shaft 571, etc. The rotating shaft 571 is connected to the support frame 572 by a bearing. When the battery… When the assembly rotates to the desired direction, the two tightening screws 574 are rotated in the opposite direction to tighten the rotating plate 573, thereby preventing the rotating plate 573 and other structures from rotating. Then, the elastic rubber frame 55 and damper 56 between the base plate 1 and the support frame 572 buffer external vibrations, thus performing vibration isolation. The support block 3 provides support, and the anti-slip rubber pad 2 provides anti-slip. When it is necessary to assist in fixing the position of the device, the operator rotates the rotating screw 62 in the two auxiliary fixing devices 6 respectively. The rotating screw 62 is threadedly connected to the lifting block 63, and the outer side of the lifting block 63 is in contact with the inner side of the connecting box 61. Therefore, the two rotating screws 62 drive the two lifting blocks 63 and the suction cups 64 below them to descend until the suction cups 64 are attached to the floor, thereby assisting in fixing the position of the device, reducing the possibility of the device moving accidentally due to collisions or other reasons, and ensuring the normal operation of the work.
