Description

Technical Field

[0001] The invention belongs to the field of wind power generation, and in particular relates to a wind power generator capable of fully automatic yaw. Background Art

[0002] With the continuous development of the new energy industry, wind power generation has become the main force in the new energy industry, and the basic structure and control logic of wind turbines are basically the same. For example, the yaw primary transmission system and saddle bridge, when the wind turbine yaws to the wind, it will drive the stator and rotor side cables of the generator (that is, the output cable and the loop cable) to rotate together. When the torsion angle reaches 850 degrees, the soft protection and cam in the yaw system of the wind turbine will be activated, and the wind turbine will not be able to continue to yaw automatically. Personnel need to remotely control or locally control the wind turbine to yaw in the opposite direction. After the cable is released, the soft protection and cam will exit the protection state, and the yaw system can resume work. Therefore, the current wind turbines have the following problems: (1) The maximum rotation angle of the saddle bridge of a traditional wind turbine is limited, which causes the wind turbine to yaw at a large angle, affecting the wiring of its output cable and loop cable, making it easy for the two to entangle and stretch, affecting power transmission; (2) When a traditional wind turbine generator set rotates to the maximum yaw angle, it cannot continue to rotate and requires manual remote control or on-site control to release the yaw cable, which increases the operation and maintenance costs; (3) During the yaw process, traditional wind turbines cannot effectively manage the wiring of cables, which often leads to friction and wear between cables, shortening the service life of the cables and increasing the failure rate and safety hazards of the wind turbines.

[0003] Based on the above problems, the present invention adopts a ring layout to replace cables to conduct electricity, thereby solving the problem of the maximum yaw angle of the wind turbine from the source, realizing fully automatic yaw control of the wind turbine, and effectively avoiding the entanglement and wear problems of the cables, reducing operation and maintenance costs and safety hazards, and has broad application prospects.

Unless otherwise specified, the "detachable connection" of the present invention can be achieved by bolts, buckles, etc.

[0016] like Figure 1 , Figure 2 A wind turbine capable of fully automatic yaw comprises a wind turbine generator set 3, a saddle bridge and a pile body 1, wherein the wind turbine generator set 3 is arranged on the saddle bridge, and the saddle bridge is installed on the top of the pile body 1 through a connecting structure 2; the connecting structure 2 comprises a base plate 101, a bearing column 102, a support plate 5, a fixed cylinder 8, a central shaft 4 and a slide plate 7; The top of the pile body 1 is fixedly connected to the base plate 101, and the top of the base plate 101 is fixedly connected to the bearing column 102; the fixed cylinder 8 is a hollow structure, which is sleeved on the bearing column 102, and the bottom of the fixed cylinder 8 is installed on the base plate 101. Specifically, the bottom of the fixed cylinder 8 is connected to the base plate 101 by bolts, and the slide plate 7 is rotatably arranged on the top of the fixed cylinder 8, and the rotation direction of the slide plate 7 is around the circumference of the bearing column 102; the central axis 4 passes through the bearing column 102, and the top of the central axis 4 is fixedly connected to the support plate 5; the top of the bearing column 102 is rotatably connected to the support plate 5, and the slide plate 7 and the saddle bridge are fixedly connected to the support plate 5; The slide plate 7 is provided with a conductive wheel 705, and the outer side surface of the fixed cylinder 8 is sleeved with a conductive ring 11, and the conductive wheel 705 contacts the conductive ring 11 to be in contact and conductive; The output cable of the wind turbine generator set 3 is electrically connected to the conductive wheel 705, and the loop cable of the wind turbine generator set 3 is electrically connected to the central axis 4. The pile body 1, the wind turbine generator set 3 and the saddle bridge are existing technologies. The pile body 1 provides a stable support foundation for the wind turbine generator set 3 and the saddle bridge, and the wind turbine generator set 3 is responsible for converting wind energy into electrical energy and is a core component of the wind power generation system. The generator of the existing wind turbine generator set 3 is connected with an output cable and a loop cable. The output cable and the loop cable pass downward through the pile body 1 and are connected to the converter. The converter is connected to the power recovery system or the power grid to complete the power recovery; wherein the output cable is the actual output cable of the current, and the loop cable is electrically connected to the converter or grounded to form a complete loop. Specifically, in the present invention, the output cable is electrically connected to the conductive wheel 705, and the conductive ring 11 can be electrically connected to the converter, the power recovery system or the power grid to achieve the connection between the output cable and the converter.

[0017] In the present invention, the wind turbine generator set 3 and the saddle bridge are supported on the support plate 5, and the load-bearing column 102 is subjected to force to transfer the gravity to the pile body 1. The fixed cylinder 8 and the slide plate 7 are not subjected to the gravity of the wind turbine generator set 3. The central axis 4, the load-bearing column 102, the fixed cylinder 8 and the pile body 1 are coaxially arranged. When the wind turbine generator set 3 yaws to face the wind, since the support plate 5 is connected to the saddle bridge, when the support plate 5 is driven, the saddle bridge and the wind turbine generator set 3 are driven to rotate around the axis of the pile body 1. At this time, the support plate 5 and the slide plate 7 rotate at the same time, while the base plate 101 and the fixed cylinder 8 remain stationary. The connection between the support plate 5 and the saddle bridge is a prior art, such as a bolt connection.

[0018] When the wind turbine generator set 3 is yawed, in some embodiments, the saddle bridge can be driven to rotate by a driving device such as a motor to align with the wind direction. In this process, since the skateboard 7, the support plate 5, the saddle bridge, and the wind turbine generator set 3 are connected as a whole, the output cable of the wind turbine generator set 3 is relatively stationary with the skateboard 7. During the yaw process, the output cable does not bend or entangle, thereby eliminating the process of yaw uncoupling of the output cable. The skateboard 7 makes a circular motion around the fixed cylinder 8, and the electricity is exported in real time through the conductive wheel 705 and the conductive ring 11.

[0019] During the rotation of the skateboard 7 of the present invention, the conductive wheel 705 and the conductive ring 11 maintain contact and conductivity in real time, so that the output cable is always in a conductive state, and can continuously output current to export electricity to the converter, power recovery system or power grid; during the yaw process, the output cable and the wind turbine 3 and the skateboard 7 remain relatively still, and the transmission cable and the fixed cylinder 8 and the converter remain relatively still. Therefore, the present invention can effectively avoid the power outage or damage problem caused by cable twisting of the wind turbine 3 during the yaw process, greatly improves the rotatable angle of the wind turbine 3, and can effectively solve the problem of yaw cable release of the wind turbine. In actual applications, there is no need for manual remote control or on-site control to perform yaw cable release, and fully automatic yaw control of the wind turbine can be achieved.

[0020] like Figure 2-Figure 4 A conductive plate 703 is fixedly connected inside the skateboard 7, a conductive column 704 is fixedly connected to the bottom of the conductive plate 703, the conductive column 704 passes through the bottom of the skateboard 7, the conductive column 704 is provided with the conductive wheel 705, and a conductive bolt 702 is fixedly connected to the top of the skateboard 7, the conductive bolt 702 is connected to the output cable of the wind turbine generator set 3, and the output cable and the conductive ring 11 are connected in sequence through the conductive bolt 702, the conductive plate 703, the conductive column 704, and the conductive wheel 705.

[0021] In the present invention, the conductive bolt 702 is fixedly connected or threadedly connected to the conductive plate 703, and both are made of metal materials to achieve current conduction; the slide plate 7 is preferably made of insulating material, which is non-conductive with other components. An inner chamber is provided inside the slide plate 7, and the conductive plate 703 is fixedly arranged in the inner chamber. The conductive column 704 is arranged downward, and the conductive bolt 702 is arranged upward. The conductive wheel 705 is made of metal and can achieve the conductive function. The outer side surface of the conductive ring 11 is conical, and the conductive wheel 705 is provided with an annular conical groove adapted to the conductive ring 11, thereby increasing the contact area between the conductive ring 11 and the conductive wheel 705 and maintaining the contact conductivity during yaw rotation through the conical limit. The present invention uses the structure of the conductive wheel 705 rotating around the conductive ring 11, so that the slide plate 7 can maintain a stable electrical connection state of the output cable during yaw rotation, ensuring the continuous output of power from the wind turbine generator set 3 without the need for yaw cable release.

[0022] Furthermore, the top of the fixed cylinder 8 is detachably connected to the annular guide rail 801 by bolts, an output shaft 9 is provided in the fixed cylinder 8, a conductive block 802 is provided in the annular guide rail 801, the top of the output shaft 9 is fixedly connected to the conductive block 802, a transverse bolt 803 is provided on the annular guide rail 801, and the transverse bolt 803 passes through the conductive block 802 and is threadedly connected to the inner side surface of the conductive ring 11.

[0023] A plurality of through holes are arranged on the wall of the fixed cylinder 8, and a plurality of output shafts 9 are respectively arranged in each through hole. The conductive block 802 is annular, and an annular groove is arranged at the bottom of the annular guide rail 801, and the conductive block 802 is located in the annular groove. The cross bolt 803 and the conductive block 802 play the function of transmitting current, and the current is transmitted to the conductive ring 11, the cross bolt 803, the conductive block 802, and the output shaft 9 in sequence through the conductive wheel 705. The output shaft 9 of the present invention is fixedly connected to the conductive block 802, and the conductive block 802 is connected to the annular guide rail 801 through the cross bolt 803. The cross bolt 803 is arranged horizontally and the output shaft 9 is arranged vertically. Therefore, the structure in which the plurality of output shafts 9 are arranged around the fixed cylinder 8 can achieve the fixing effect of the annular guide rail 801, and can also play the function of dispersing current. Dispersing current can reduce the heat accumulation during the current transmission process and improve the power transmission efficiency. The bottom of each output shaft 9 of the present invention is connected to the aforementioned transmission cable through a cable connector. Specifically, there are multiple transmission cables, and one end of each transmission cable is connected to the bottom of each output shaft 9 respectively. After each transmission cable is bundled, the other end thereof is finally connected to the inverter, power recovery system or power grid, thereby realizing the output function of power.

[0024] Furthermore, the top of the annular guide rail 801 is fixedly connected to an annular block 804, and the bottom of the slide plate 7 is provided with a slot 706 adapted to the annular block 804, and the slot 706 is nested on the annular block 804. The annular block 804 and the slot 706 cooperate to achieve a restraining effect on the slide plate 7.

[0025] Further, the slide plate 7 is provided with a plurality of slide plates 7, and the plurality of slide plates 7 are arranged around the bearing column 102. The conductive bolts 702 of the plurality of slide plates 7 are provided with an annular conductor 10, and the annular conductor 10 is provided around the bearing column 102, and the annular conductor 10 is connected to the output cable of the wind turbine generator set 3. There are multiple output cables, and the annular conductor 10 is provided with multiple bundles, one end of each annular conductor 10 is respectively wound around a plurality of conductive bolts 702, and the other end of each annular conductor 10 is respectively connected to each output cable after passing through the support plate 5, and the portion of the annular conductor 10 passing through the support plate 5 is provided with a cable sleeve.

[0026] In the present invention, the slide plate 7 and the parts connected thereto are preferably provided with at least two, the purpose of which is to relatively increase the contact area between the conductive wheel 705 and the conductive ring 11 through the arrangement of two or more slide plates 7, thereby improving the stability of contact conduction and the efficiency of power transmission.

[0027] Furthermore, an annular groove is provided at the bottom of the support plate 5, and the top of the slide plate 7 is connected to the top surface of the annular groove by a connecting bolt 701, so as to realize the fixed connection between the slide plate 7 and the support plate 5; and one end of the conductive bolt 702 connected to the annular wire 10 is provided in the annular groove. The annular groove wraps the connecting end of the conductive bolt 702 and the annular wire 10 to play a protective role and avoid exposure.

[0028] Furthermore, an insulating plate 6 is arranged under the support plate 5, the conductive bolts 702 and the connecting bolts 701 pass through the insulating plate 6, the supporting column 102 passes through the insulating plate 6, a mounting groove is arranged at the bottom of the insulating plate 6, the slide plate 7 is arranged in the mounting groove, and the outer side surface of the insulating plate 6 is fixedly connected to the insulating shell 707, and the insulating shell 707 wraps the conductive wheel 705 and the conductive ring 11.

[0029] The insulating plate 6 is provided with a hollow portion, and the bearing column 102 passes through the hollow portion. Since the connecting bolt 701 passes through the insulating plate 6, the insulating plate 6 rotates together with the slide plate 7, which can ensure the rotation synchronization of multiple slide plates 7. The insulating housing 707 is annular and wraps the conductive wheel 705 and the conductive ring 11 to avoid exposure.

[0030] Furthermore, a mounting hole is provided on the top of the pile body 1, the bottom of the central axis 4 is located in the mounting hole, the top of the central axis 4 is fixedly connected to the support plate 5, the central axis 4 is connected to a driving device 402 for driving its rotation, the driving device 402 can be fixedly installed in the mounting hole, the central axis 4 is connected to the loop cable of the wind turbine 3 through a second conductor 403, a conductive sleeve 401 is provided on the bottom of the central axis 4, the central axis 4 and the conductive sleeve 401 can rotate relative to each other, and keep the second conductor 403 in contact with the conductive sleeve 401 during rotation, and the conductive sleeve 401 is connected to a grounding cable.

[0031] Specifically, the central axis 4 is a hollow structure, and a cable is arranged inside the central axis 4. The top of the cable is connected to the second conductor 403, and the bottom of the cable is fixedly connected to a conductive sheet, which is located on the outer side of the central axis 4, and is annular and wraps the central axis 4; the conductive sleeve 401 is in contact with each conductive sheet and is conductive; during the yaw process, the conductive sheet rotates relative to the conductive sleeve 401, and the conductive sleeve 401 is fixedly connected to the inner wall surface of the pile body 1. The present invention realizes the conductive function by contacting the conductive sheet and the conductive sleeve 401, and the conductive sheet and the conductive sleeve 401 are both made of metal. The conductive sleeve 401 can be grounded through a grounding cable, and can also be connected to the negative pole in the power recovery system through a cable, so that the present invention constitutes a complete loop. Since the loop cable is relatively stationary with the central axis 4 and the wind turbine 3, and the grounding cable is relatively stationary with the pile body 1, the loop cable and the grounding cable can be kept from being twisted or entangled during the yaw process.

[0032] The driving device 402 is a prior art, such as a motor and gear, a motor and a synchronous belt. When the wind turbine generator set 3 yaws to face the wind, the driving device 402 drives the central shaft 4 to rotate, and the central shaft 4 drives the support plate 5 and the wind turbine generator set 3 to rotate around the axis of the pile body 1.

[0033] The workflow of the present invention is as follows: When the wind turbine generator needs to yaw to face the wind, the driving device 402 is started to drive the central shaft 4 to start rotating. The rotation of the central shaft 4 drives the rotation of the support plate 5, and then the wind turbine generator set 3 and the saddle bridge are rotated around the axis of the pile body 1 to yaw and align with the wind direction. The alignment process and principle are prior art. In this process, the slide plate 7 rotates with the rotation of the support plate 5, but it remains relatively still with the output cable of the wind turbine generator set 3, avoiding the twisting and entanglement of the output cable.

[0034] The conductive plate 703 and the conductive column 704 inside the slide plate 7 ensure that the current can form a stable electrical connection with the conductive ring 11 outside the fixed cylinder 8 through the conductive wheel 705. This design ensures that the current of the wind turbine generator set 3 can be continuously and stably output during the yaw process without being affected by the yaw action.

[0035] At the same time, the setting of the annular guide rail 801 and the conductive block 802 further enhances the transmission stability of the current. The cross bolt 803 passes through the conductive block 802 and is threadedly connected to the inner side of the conductive ring 11. The conductive wheel 705 transmits the current through the conductive ring 11, the cross bolt 803, the conductive block 802 and the output shaft 9 in sequence; the output shaft 9 finally outputs the power to the converter, the power recovery system or the power grid through the transmission cable. On the other hand, the grounding line or the negative return circuit formed by the loop cable, the conductive sheet, the conductive sleeve 401 and the grounding cable enables the present invention to form a complete current transmission path, ensuring that the current can be efficiently conducted and avoiding the twisting and winding of the loop cable.

[0036] In addition, the arrangement of the insulating plate 6 and the insulating housing 707 effectively protects the circuit system and prevents the risk of current leakage and short circuit. The mounting groove at the bottom of the insulating plate 6 firmly fixes the slide plate 7, while the insulating housing 707 wraps the conductive wheel 705 and the conductive ring 11, providing additional safety protection.

[0037] During the entire yaw process, the wind turbine generator set 3 can generate electricity continuously and stably, and output the electric energy to the power grid through the connection structure 2. This innovative design greatly increases the rotatable angle of the wind turbine generator set 3, effectively solves the problem of yaw cable release of the wind turbine generator, and in actual application, there is no need for manual remote control or local control to perform yaw cable release, thus realizing fully automatic yaw control of the wind turbine generator.

[0038] The embodiments described above are only descriptions of the preferred modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
