[0026] See also Figure 1-4 The present invention provides a technical solution: a circular wind turbine bidirectional seismic support, comprising a shock absorber 1 and a support bar 2, the shock absorber 1 comprising a mounting sleeve 101, a slider 102 being slidably connected between the side walls of the inner cavity of the mounting sleeve 101, a sliding rod 103 being fixedly connected to the bottom of the slider 102, and the sliding rod 103 passing through the bottom of the mounting sleeve 101, a first spring 104 being fixedly connected between the top of the slider 102 and the top of the inner cavity of the mounting sleeve 101, and a mounting rod 105 being fixedly connected to the top of the mounting sleeve 101;

[0027] A circular fan 3 is installed on the top of the support bar 2, and mounting columns 4 are symmetrically inserted at both ends of the support bar 2. The bottom of the mounting column 4 passes through the support bar 2 and is screwed with a first nut 5. The top of the mounting column 4 is fixedly connected to a limit block 6, and the top of the limit block 6 is fixedly connected to a first connecting column 7. The end of the first connecting column 7 away from the limit block 6 is detachably mounted with a shock absorber 1, and the end of the shock absorber 1 away from the first connecting column 7 is detachably mounted with a vertical support rod 8;

[0028] The two sets of limit blocks 6 are symmetrically fixed with a first hinge seat 9 on one side away from each other. The first hinge seat 9 is hinged with a second connecting column 10. The end of the second connecting column 10 away from the first hinge seat 9 is detachably connected to the shock absorber 1. The end of the shock absorber 1 away from the second connecting column 10 is detachably installed with an oblique support rod 11.

[0029] The outer walls of the first connecting column 7 and the second connecting column 10 are both screwed with a first connecting sleeve 12, and the outer wall of the sliding rod 103 is provided with a first external thread that cooperates with the first connecting sleeve 12;

[0030] The outer walls of the vertical support rod 8 and the oblique support rod 11 are both screwed with a second connecting sleeve 13, and the outer wall of the mounting rod 105 is provided with a second external thread that cooperates with the second connecting sleeve 13. By adopting the connection method of the first connecting sleeve and the second connecting sleeve, the shock absorber can be easily disassembled and installed, thereby facilitating the replacement of the shock absorber.

[0031] Specifically, the inner diameter of the first connecting sleeve 12 is equal to the inner diameter of the second connecting sleeve 13 , and the internal threads are the same, so that the first connecting sleeve and the second connecting sleeve can be used interchangeably.

[0032] Specifically, it also includes a mounting bar 14, the vertical support rod 8 and the mounting bar 14 are fixedly connected by bolts, and a slide groove 15 is provided at the bottom of both sides of the mounting bar 14, and the slide groove 15 is slidably connected to a slide seat 16, and a second hinge seat 17 is fixed to the bottom of the slide seat 16, and the oblique support rod 11 is hinged to the second hinge seat 17. By setting the mounting bar, the seismic bracket can be installed in an integrated manner during installation, thereby improving the installation efficiency of the seismic bracket, and the oblique support column and the mounting bar are slidably connected by the slide seat, so that the angle between the oblique support column and the vertical support column can be adjusted, thereby adjusting the shock absorption effect of the oblique support column.

[0033] Specifically, limiting grooves 18 are provided on both side walls of the mounting strip 14, and the limiting grooves 18 are connected to the slide grooves 15. Bolt columns 19 that cooperate with the limiting grooves 18 are symmetrically fixed to both side walls of the slide 16. The bolt columns 19 pass through the limiting grooves 18 and are screwed with second nuts 20, so that the sliding of the slide is more stable, and after adjusting the position of the slide, it can be locked and fixed by the cooperation of the second nut and the bolt column.

[0034] Specifically, a second spring 106 is sleeved on the outer wall of the slide rod 103 , and the second spring 106 is located between the slider 102 and the bottom of the inner cavity of the installation sleeve 101 , so as to further improve the shock absorption effect of the shock absorber.

[0035] Specifically, the bottom of the installation sleeve 101 is a threaded detachable structure, so that the bottom of the installation sleeve can be opened, and then the sliding rod and the slider can be removed to replace the first spring.

[0036] Specifically, a third spring 21 is sleeved on the outer wall of the mounting column 4, and the third spring 21 is located between the limit block 6 and the support bar 2. The third spring can further reduce the vibration force between the support bar and the mounting column.

[0037] Example 1:

[0038] First, assemble the anti-seismic bracket. During assembly, first, sleeve the third spring 21 on the outer wall of the mounting column 4 and locate it at the bottom of the limit block 6. Then, insert the mounting column 4 into both ends of the support bar 2, and make the third spring 21 located between the limit block 6 and the support bar 2. Then, use the first nut 5 from the bottom of the support bar 2 to lock and secure the mounting column 4.

[0039] Then align one end of the sliding rod 103 of the shock absorber 1 with the first connecting column 7, and then rotate the first connecting sleeve 12, and rotate the first connecting sleeve 12 between the sliding rod 103 and the first connecting column 7, so as to fix the shock absorber 1 to the first connecting column 7, and then align the mounting rod 105 of the shock absorber 1 with the vertical support rod 8, and then rotate the second connecting sleeve 13, and rotate the second connecting sleeve 13 between the mounting rod 105 and the vertical support rod 8, so as to complete the installation of the shock absorber 1. The connection method of the connecting sleeve is not only convenient for installation and disassembly, but also can realize the smooth transmission of the vibration force without generating lateral force component, so as to make the shock absorption effect of the shock absorber 1 better. The connection method between the oblique support rod 11 and the second connecting column 10 and the shock absorber 1 is consistent with that of the first connecting column 7;

[0040] Then, one end of the vertical support rod 8 is fastened to the mounting bar 14 by bolts, and one end of the oblique support rod 11 is fastened to the second hinge seat 17 by bolts. Then, according to the requirements of the installation environment, the slide seat 16 and the second hinge seat 17 are slid to adjust the angle of the oblique support rod 11 so that the oblique support rod 11 can achieve different shock absorption effects.

[0041] Finally, a circular fan (e.g., an axial fan) is bolted to the top of support bar 2, and two sets of seismic brackets are used to lock and secure the front and rear sides of the circular fan. Furthermore, a strip-shaped mounting slot is provided through the top of support bar 2, which mates with the mounting hole of the circular fan. This allows the installation position of the circular fan to be adjusted during installation and accommodates circular fans of different sizes. During installation, bolts are inserted into the mounting hole of the circular fan and passed through the strip-shaped mounting slot. Nuts are then used to lock and secure the bottom of support bar 2, completing the installation of the circular fan. The entire unit is then mounted in its working position using mounting bar 14.

[0042] When vibration occurs, the vibration in the vertical direction is transmitted to the shock absorber 1 of the vertical support rod 8, and the up and down vibration drives the sliding rod 103 and the slider 102 to slide up and down along the inner wall of the mounting sleeve 101, thereby squeezing the first spring 104 and the second spring 106 to consume the vibration force, thereby preventing the vibration force from being transmitted to the mounting bar 14 and causing it to fall off. The vibration in the oblique direction is transmitted to the shock absorber 1 of the oblique support rod 11, pushing the slider 102 to slide, squeezing the first spring 104 and the second spring 106 to consume the vibration force.

[0043] When the shock absorber 1 fails after being used for a period of time, the first connecting sleeve 12 and the second connecting sleeve 13 are rotated respectively, and then the shock absorber 1 is removed and replaced with a new shock absorber 1, or after the shock absorber 1 is removed, the bottom of the mounting sleeve 101 is rotated, and then the sliding rod 103 and the slider 102 are taken out and the first spring 104 and the second spring 106 are taken out for replacement, and then reinstalled. The disassembly process is simple and convenient.
