Description

Technical Field

[0002] Wind power equipment is an elevated facility. The wind turbine stands in the wind and is in an open-air environment for a long time. Most of the mass of the wind turbine is concentrated on the nacelle, and the tower is tens of meters high. The stability of the wind turbine itself is supported by a part buried underground. The wind turbine has a high center of gravity and is also affected by the unbalanced force of the blades during use. Therefore, the stability of the wind turbine is a prerequisite for its normal operation. Due to the particularity of its structure, it cannot achieve its own shock absorption by simply adding cables or setting reinforcement measures like other elevated facilities. Therefore, research on the safe operation of wind turbines is of great practical significance.

[0003] When the existing wind turbine tower is put into use, the tower will shake slightly due to wind load, blade rotation, mechanical vibration and other factors when the wind turbine is running, causing the internal cables to swing synchronously with the tower.

At this time, the fourth return spring can support and dampen the connecting rod through its own restoring force. Furthermore, by filling the shock-absorbing sleeve with hydraulic oil, when the connecting rod is pressed downward, the hydraulic oil flows through the reflux hole to the top of the contact surface between the connecting rod and the shock-absorbing sleeve, and shock-absorbing is performed through hydraulic pressure. By providing multiple sets of articulated states, multi-faceted shock absorption of the tower can be guaranteed, thereby improving the shock absorption effect, thereby achieving the purpose of facilitating the device to perform adaptive shock absorption on the wind power tower.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides an adaptive shock absorbing device for a wind power generation tower, comprising a tower base 1, a gear box 2 is installed at the top of the tower base 1, a suspension wire notch is arranged above the tower outlet at the bottom of the tower base 1, a stainless steel roller 10 is arranged below the tower outlet at the bottom of the tower base 1, a fan blade 3 is arranged on the outside of the gear box 2, a cable 4 is arranged at one end of the gear box 2, a steel sheath 8 is arranged at one end of the tower outlet of the cable 4, a cloth rope 9 is connected to the steel sheath 8, a shock absorbing mechanism 5 is installed inside the tower base 1, a disassembly and assembly mechanism 6 is arranged at one end of the shock absorbing mechanism 5, and a buffer mechanism 7 is arranged on the outside of the tower base 1.

[0034] The above scheme is adopted: wind energy is captured by fan blades 3, and converted into mechanical energy by gear box 2, and then converted into electrical energy for transmission through cable 4. Since spring shock absorption is used inside the wind tower, cable 4 still swings, and friction and wear occur with the tower mouth at the tower outlet. Cloth rope 9 is now used to lift steel sheath 8, so that cable 4 is suspended in the air, and does not directly contact the tower body when cable 4 swings. The cable 4 suspended in the tower acts as a pendulum damper when swinging, which can reduce the shaking of the tower body and improve the wind resistance of the tower body. When the cloth rope 9 breaks, cable 4 contacts with stainless steel roller 10. When cable 4 swings, steel sheath 8 rolls and rubs with stainless steel roller 10, which still does not damage cable 4. An alarm is connected. After breaking, the alarm sounds, and maintenance personnel can receive fault information and repair it in time.

[0035] like Figures 1 to 8 As shown, the shock absorbing mechanism 5 includes a first return spring 501, a first mounting ring 502 and a second return spring 503. The first return spring 501 is fixed to the inner wall of the tower seat 1. The first mounting ring 502 is fixed to one end of the first return spring 501. Several groups of first return springs 501 are arranged. The first return springs 501 are evenly spaced about the central axis of the tower seat 1. The first return spring 501 is used to squeeze the first mounting ring 502 and keep it moving inward. Several groups of observation grooves are opened on the outer wall of the first mounting ring 502. At least one group of observation grooves among the several groups of observation grooves is provided with a spirit level.

[0036] like Figures 1 to 8 As shown, a second return spring 503 is fixed to the inner wall of the tower seat 1, and a second mounting ring 504 is fixed to one end of the second return spring 503. Several groups of second return springs 503 are arranged, and the second return springs 503 are evenly spaced about the central axis of the tower seat 1. The second return spring 503 is used to squeeze the second mounting ring 504 and keep it moving inward. Several groups of observation grooves are opened on the outer wall of the second mounting ring 504, and at least one group of the observation grooves is provided with a spirit level. Rubber shock-absorbing pads 505 are arranged inside the first mounting ring 502 and the second mounting ring 504.

[0037] The above scheme is adopted: by arranging the cable 4 between the first mounting ring 502 and the second mounting ring 504, and arranging rubber shock-absorbing pads 505 on the contact surfaces between the cable 4 and the first mounting ring 502 and the second mounting ring 504, the rubber shock-absorbing pads 505 can absorb high-frequency vibration energy, and through the extrusion of the first return spring 501 and the second return spring 503, the position of the cable 4 can be maintained in the central hollow of the tower seat 1, thereby preventing the device from shaking slightly when it is put into use, causing the internal cables to swing synchronously with the tower.

[0038] like Figures 1 to 8As shown, the disassembly and assembly mechanism 6 includes a mounting seat 601, a first limiting rod 602 and a limiting plate 603. The mounting seat 601 is fixed at the top of the first return spring 501, the top of the mounting seat 601 is fixed with the first limiting rod 602, the top of the first limiting rod 602 is fixed with the limiting plate 603, the outer wall of the first limiting rod 602 is sleeved with an extrusion plate 604, the mounting seat 601 is provided with a plurality of groups, the mounting seats 601 are arranged at equal intervals about the central axis of the first mounting ring 502, the outer wall of the first limiting rod 602 is close to the inner wall of the extrusion plate 604, the first limiting rod 602 and the extrusion plate 604 are slidably connected, and the diameter of the extrusion plate 604 is larger than the diameter of the limiting plate 603.

[0039] like Figures 1 to 8 As shown, a limiting groove 605 is provided at the bottom end of the second mounting ring 504, and a second limiting rod 606 is movably connected inside the second mounting ring 504. A plurality of limiting grooves 605 are provided, and the limiting grooves 605 are evenly spaced about the central axis of the second mounting ring 504. The outer wall of the second limiting rod 606 is close to the inner wall of the second mounting ring 504. The second limiting rod 606 is slidably connected to the second mounting ring 504. Two groups of second limiting rods 606 are provided, and the second limiting rods 606 are symmetrically distributed about the central axis of the limiting groove 605. A third reset spring 607 is sleeved on the outer wall of the second limiting rod 606, and a limiting block 608 is fixed outside the second limiting rod 606. The third reset spring 607 is used to squeeze the second limiting rod 606 and the limiting block 608 and keep them moving inwardly. An inclined surface is provided at one end of the limiting block 608.

[0040] The above scheme is adopted: by dragging the bottom of the first mounting ring 502 and pressing the second mounting ring 504, the position of the extrusion disk 604 is moved up and contacts the inclined surface of the limit block 608, and when in contact, the limit block 608 and the second limit rod 606 are squeezed inward, so that after the extrusion disk 604 passes the limit block 608, the third reset spring 607 resets the limit block 608 and lifts the extrusion disk 604, so that the extrusion disk 604 contacts the limit disk 603, and pulls in the opposite direction to separate the first mounting ring 502 and the second mounting ring 504. At this time, the internally worn rubber shock-absorbing pad 505 can be replaced.

[0041] like Figures 1 to 8As shown, the buffer mechanism 7 includes a pressure relief ring 701, a first connecting seat 702 and a shock absorbing sleeve 703. The pressure relief ring 701 is fixed to the outside of the tower seat 1. The bottom end of the tower seat 1 is provided with a first connecting seat 702, and the shock absorbing sleeve 703 is hinged inside the first connecting seat 702. The bottom end of the pressure relief ring 701 is fixed with a second connecting seat 704, and the second connecting seat 704 is hinged inside a connecting rod 705. The diameter of the pressure relief ring 701 is greater than the diameter of the tower seat 1. The first connecting seat 702 is provided with a plurality of groups. The first connecting seats 702 are arranged at equal intervals about the central axis of the tower seat 1. The inner wall of the shock absorbing sleeve 703 is close to the central axis of the tower seat 1. Near the outer wall of the connecting rod 705, the shock-absorbing sleeve 703 and the connecting rod 705 are in contact with each other, the interior of the shock-absorbing sleeve 703 is filled with hydraulic oil, and the second connecting seat 704 is provided with a plurality of groups, and the second connecting seats 704 are arranged at equal intervals about the central axis of the pressure relief ring 701. A fourth reset spring 706 is fixed to the bottom end of the connecting rod 705, and a reflux hole 707 is opened inside the shock-absorbing sleeve 703. The fourth reset spring 706 is used to squeeze the connecting rod 705 and keep it moving upward. The reflux holes 707 are provided with a plurality of groups, and the reflux holes 707 are arranged at equal intervals about the central axis of the shock-absorbing sleeve 703.

[0042] The above solution is adopted: the pressure relief ring 701 is tilted downward to make the second connection seat 704 and the connection rod 705 move downward, and at this time the fourth return spring 706 can support and dampen the connection rod 705 through its own restoring force.

[0043] In another embodiment, the tower seat is also provided with a waterproof system, and a drainage trough is provided at the bottom of the tower seat for drainage. On the other hand, a one-way water outlet is also provided on the top of the tower seat. The one-way water outlet is covered by a thin iron sheet, and the upper end of the thin iron sheet is connected to the outer wall of the tower seat by a hinge. When the water level inside the tower seat reaches the set height of the one-way water outlet, the accumulated water will squeeze the thin iron sheet due to gravity to open it, and the one-way water outlet is arranged below the shock absorbing mechanism 5 to prevent the accumulated water from overflowing the shock absorbing mechanism 5, causing the performance of parts such as springs to be affected by the accumulated water and deteriorating. At the same time, with the drainage trough, double drainage is performed to cope with the situation of large amount of water accumulated in a short time. Finally, a cable sealing sleeve is installed at the cable entrance, i.e., the tower outlet, to ensure that there is no gap between the cable and the hole wall. The cable sealing sleeve is made of rubber or water-repellent cloth, so that the cable is not rigidly fixed, and the cable has a relatively certain displacement space to reduce the friction effect on the cable.

[0044] The working principle and use process of the present invention are as follows: wind energy is captured by the fan blades 3, and converted into mechanical energy by the gear box 2, and then converted into electrical energy, and the electrical energy is transmitted through the cable 4. Since the cable 4 is in a suspended state, strong external wind may cause the cable outside the tower to swing, and long-term vibration may cause wear of the cable insulation layer, loose joints or metal fatigue. The cable 4 is arranged between the first mounting ring 502 and the second mounting ring 504, and a rubber shock-absorbing pad 505 is arranged on the contact surface between the cable 4 and the first mounting ring 502 and the second mounting ring 504. The rubber shock-absorbing pad 505 can absorb high-frequency vibration energy, and through the extrusion of the first return spring 501 and the second return spring 503, the position of the cable 4 can be maintained in the central hollow of the tower seat 1, thereby preventing the device from shaking slightly when it is put into use, causing the internal cable to swing synchronously with the tower. Furthermore, since the outside of the first mounting ring 502 and the second mounting ring 504 is provided with an observation groove, the user can install a miniature camera at the groove according to needs to observe the volume of the rubber shock-absorbing pad 505, thereby judging the overall life of the shock-absorbing device, and When the rubber shock-absorbing pad 505 is worn out after long-term use, the user enters the tower base 1, drags the bottom of the first mounting ring 502 and presses the second mounting ring 504, so that the position of the extrusion plate 604 moves up and contacts the inclined surface of the limit block 608, and when in contact, the limit block 608 and the second limit rod 606 are pressed inward, so that after the extrusion plate 604 passes the limit block 608, the third reset spring 607 resets the limit block 608 and lifts the extrusion plate 604, so that the extrusion plate 604 contacts the limit plate 603, and then pulls the first mounting ring 502 in the opposite direction. 02 and the second mounting ring 504 are detached, at which time the rubber shock-absorbing pad 505 that has been worn inside can be replaced. Furthermore, during installation, the limit plate 603 and the limit groove 605 are aligned and pressed. When the limit plate 603 contacts the inclined surface of the limit block 608, the limit block 608 and the second limit rod 606 are squeezed inward, so that after the limit plate 603 passes the limit block 608, the third reset spring 607 resets the limit block 608 to the bottom of the limit plate 603, thereby resetting the limit plate 603 and completing the disassembly and assembly of the rubber shock-absorbing pad 505.
