Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind power generation equipment, in particular to a wind power generation equipment mounting device. BACKGROUND

[0002] Small wind power generation equipment is widely used in remote areas, outdoor lighting, communication base stations and other scenes due to its flexibility and applicability. However, its installation stability has always been a technical difficulty. The existing installation devices mostly adopt fixed structures or simple spring buffers, which are difficult to balance the shock absorption requirement in normal state and the stability requirement in extreme wind conditions.

[0003] When encountering strong wind weather, the rapid wind load will cause the fan blade speed to increase rapidly, and the whole device will produce strong shaking. The existing buffer mechanism not only cannot effectively absorb energy under this condition, but also may amplify the amplitude due to excessive movement, eventually leading to device structure fatigue, loose connecting parts and even overall overturning.

[0004] Therefore, there is an urgent need for a mounting device that can automatically adjust its state according to the wind conditions to realize "normal buffer, strong wind rigidity" adaptive switching, so as to fundamentally improve the reliability and life of the device in harsh environments. SUMMARY

The outer surface of the inner tube 601 has multiple insertion holes 603, and the outer surface of the outer tube 6 has through holes 604. A spring damper 602 is fixedly installed in the inner cavity of the inner tube 601. The outer tube 6 is connected to the inner tube 601 through the spring damper 602.

The top surface of the base 1 is provided with multiple polygonal holes 101. The shape of the cross-section of the inner cavity of the polygonal hole 101 matches the shape of the cross-section of the outer surface of the polygonal outer frame 503.

A telescopic extension block 803 is fixedly installed at the bottom of the adjusting block 802. A gravity block 804 is fixedly installed at the bottom of the telescopic extension block 803. The connecting rope 405 is connected to the position adjustment unit; the position adjustment unit responds to the tension change of the connecting rope 405 and drives the snap-fit ​​unit to switch the corresponding shock-absorbing unit between the buffer state and the rigid connection state.

[0023] Working principle: First, assemble the entire device. The operator pulls the handle 504 upwards, causing the polygonal outer frame 503 to disengage from the polygonal hole 101 at the top of the base 1. Then, rotate the handle 504. The rotation of the handle 504 is transmitted to the adjusting rod 501 through the elastic telescopic rod 502 and the polygonal outer frame 503. Since the adjusting rod 501 is connected to the adjusting tube 5 by a thread, the rotational motion is converted into linear motion, thereby adjusting the total height of the adjusting tube 5 and the adjusting rod 501 after combination. This changes the contact position between the bottom inner tube 601 and the ground. By adjusting them one by one, the bottom contact surfaces of all inner tubes 601 are made to be on the same horizontal plane, ensuring that the base 1 is in a horizontal state after installation. After the adjustment is completed, release the handle 504. Under the elastic force of the elastic telescopic rod 502, the polygonal outer frame 503 is reinserted into the corresponding polygonal hole 101. By using the polygonal fit, the adjusting rod 501 and the structure connected to it cannot rotate without external force, thus locking the adjustment height. Subsequently, the locking rod 301 at the bottom of the fan blade assembly 3 is connected to the through holes on the sliders 402 on both sides to complete the installation. At this time, the connecting rope 405 passes through the circular disc 4, the arc rod 404 and the base 1 and is connected to the two sliders 801 on the same side. Under the elastic force of the first spring 403 and the third spring 805, the connecting rope 405 is in a taut state, while the base 1 remains horizontal. Through the multiple insertion holes 603 set on the inner tube 601 and the telescopic tube 704, it is ensured that the insertion rod 701 can always find the corresponding insertion hole 603 to lock in different height adjustment states. Similarly, the gravity block 804 drives the telescopic extension block 803 to stretch downward under its own weight until the gravity block 804 contacts the ground. The telescopic extension block 803 ensures that the adjustment block 802 can always effectively push the side plate 703 to complete the locking action in different installation heights. When encountering windy weather, the strong wind drives the fan blade assembly 3 to rotate. Taking the fan blade assembly 3 rotating to the left as an example: The fan blade assembly 3 drives the left slider 402 to rotate in the left semi-circular groove 401 via the lever 301 and compresses the left first spring 403. This action causes the left connecting rope 405 to become loose. As the connecting rope 405 on the left side becomes slack, the two sliding rods 801 symmetrically arranged on the left side slide along the T-shaped rod 8 towards the outside of the base 1 under the elastic force of their respective third springs 805, and the sliding rods 801 drive the adjusting blocks 802 on them to move synchronously. When the adjusting block 802 moves, its inclined surface 8021 first contacts and slides over the side plate 703 on the same side. Since the inclined surface length of the inclined surface 8021 is fixed, only when the slider 402 rotates to a specific angle, which corresponds to the high wind threshold, and the adjusting block 802 moves a sufficient distance, will the inclined surface 8021 completely pass over the side plate 703. Then the plane 8022 of the adjusting block 802 contacts the side plate 703. When the plane 8022 continues to move, it will push the side plate 703 to move towards the outer tube 6. At this time, the movement of the side plate 703 overcomes the elastic force of the second spring 702, pushing the insertion rod 701 through the through hole 604 on the outer tube 6 and finally inserting it into the insertion hole 603 on the inner tube 601 that is aligned with it. At this time, the insertion rod 701 rigidly connects the outer tube 6 and the inner tube 601 together, making the shock absorption buffer unit that originally achieved the buffering function through the spring damper 602 a rigid connection, which greatly improves the impact resistance and anti-shaking ability of this side, thereby enhancing the stability of the entire device in strong winds. When the wind weakens, the fan blade assembly 3 returns to its original position under the rebound force of the first spring 403 on the right. The fan blade assembly 3 drives the left slider 402 to reset, and the first spring 403 on the left extends, tightening the left connecting rope 405 again. The tension of the connecting rope 405 pulls the left slide bar 801 to overcome the elastic force of the third spring 805 and slide towards the center of the base 1, returning to the initial position. The adjusting block 802 then resets, and its plane 8022 disengages from contact with the side plate 703. Under the elastic force of the second spring 702, the insertion rod 701 is pulled back, causing it to exit from the insertion hole 603 of the inner tube 601 and retract back into the through hole 604 of the outer tube 6. Utilizing the buffering function provided by the spring damper 602 between the outer tube 6 and the inner tube 601, the equipment is allowed to absorb energy through shaking under normal wind conditions, thus protecting the structure. If the fan blade assembly 3 rotates to the right, it will cause the same structure on the right to perform the same rigid switching and reset process described above.
