Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to a wind generator set. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It mainly includes a wind rotor, a generator, a tower, a control system and a gearbox. A wind turbine does not produce greenhouse gases or other pollutants. It is an inexhaustible source of energy. Although the initial investment is large, the operating cost is low and the long-term benefits are significant.

[0003] Wind turbines require regular maintenance to ensure their efficient and safe operation. Maintenance personnel need to climb towers that are tens or even hundreds of meters high. High-altitude work may cause psychological pressure such as fear and anxiety to maintenance personnel, affecting work efficiency and safety, and posing a risk of falling. Therefore, those skilled in the art provide a wind turbine to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to provide a wind turbine generator set in view of the problems existing in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a wind turbine generator set, comprising a wind turbine generator set body, a protective structure, a storage structure and a driving structure,

[0006] The wind turbine body includes a tower;

[0008] The protective structure includes a fixed ring sleeved on the outer wall of the tower, a travel ring 1 sleeved on the outside of the tower and located below the fixed ring, a lower rotating seat fixed on the outer wall of the travel ring 1 and distributed in a circular array, an upper rotating seat fixed on the outer wall of the fixed ring and distributed in a circular array, a shear arm 1 rotatably installed inside the lower rotating seat, a shear arm 2 rotatably installed inside the upper rotating seat and with one end located inside the shear arm 1, an air cushion fixed between the shear arm 1 and the shear arm 2, a travel groove 1 arranged in a circular array inside the tower, two groups of regulating pumps fixed on the inner wall of the top cover and connected to the air cushion through a hose, and a central shaft rotatably installed at the center of the shear arm 1 and one end of the shear arm 2;

[0009] The driving structure comprises a ring seat fixedly arranged on the inner wall of the tower and symmetrically distributed, and a rotating ring rotatably installed inside the ring seat.

[0010] Preferably, the air cushion is hollow inside, and a plurality of mounting holes are arranged inside the air cushion in a circular array, and the inner walls of the mounting holes are connected by the air cushion. The air cushion is hollow inside, which is convenient for filling gas inside so that the air cushion can be expanded. The mounting holes allow the gas in the air to pass through the air cushion to avoid being directly intercepted by the air cushion, thereby ensuring the stability of the tower itself.

[0011] Preferably, the regulating pump includes an air suction pump and an air supply pump, the suction end of the air suction pump is connected to the air cushion through a hose, the output end of the air supply pump is connected to the air cushion through a hose, and the top end of the shear arm is provided with a connecting piece connected to the outer wall of the upper end of the air cushion. The air suction pump sucks the gas on the inner wall of the inflated air cushion through the hose, and the air supply pump delivers gas into the air cushion through the hose, thereby inflating the air cushion.

[0012] Preferably, a travel groove is provided inside the shear arm 1, the central axis is located inside the travel groove, and one end of the shear arm 2 is located inside the travel groove. The travel groove allows the shear arm 2 to move inside the shear arm 1, and the shear arm 1 and the shear arm 2 are rotatably mounted relative to each other via the central axis.

[0013] Preferably, an adjustment plate is arranged above the storage tube, which is distributed in a circular array and sleeved on the outer side of the second shear arm. A mounting groove is provided inside the lower end of the adjustment plate, and a mounting shaft is connected to the inner wall of the mounting groove. The adjustment plate is sleeved on the outer side of the first shear arm and the second shear arm during use, and the first shear arm and the second shear arm are stored when not in use, and the first shear arm and the second shear arm are sleeved inside the adjustment plate, thereby storing and protecting the air cushion inside the first shear arm and the second shear arm, and the mounting shaft is rotatably supported by the mounting groove, while providing installation space for the torsion spring and the connecting block, and providing rotation space for the connecting block.

[0014] Preferably, a connecting block connected to the upper end of the receiving tube is sleeved on the outer side of the center of the installation shaft, and a torsion spring is sleeved on the outer side of the installation shaft, which is symmetrically distributed and has two ends respectively connected to the connecting block and the inner wall of the installation groove. The installation shaft rotates inside the connecting block, and the connecting block is supported by the receiving tube, so that the adjustment block is torsionally elastically supported by the torsion spring, and the adjustment plate is rotationally supported above the receiving tube, and the elastic force of the torsion spring is applied to the adjustment plate.

[0015] Preferably, the upper outer wall of the tower is provided with symmetrically distributed travel grooves three, the inner wall of the top cover is provided with symmetrically distributed travel blocks slidably mounted inside the travel grooves three, the outer wall of the travel block is provided with travel plates three slidably mounted on the outer wall of the tower and corresponding to the travel grooves three, and the inner wall of the upper end of the tower is provided with a hydraulic rod whose telescopic end is connected to the upper end of the travel block. The travel block slides inside the travel grooves three and is slidably mounted inside the tower. By driving the travel plates three to move, the travel blocks are reset to drive the travel plates three to shield the travel grooves three, so as to prevent rainwater and foreign objects from entering the tower through the travel grooves three. The hydraulic rod drives the travel block to travel longitudinally, and the top cover is linked to adjust the longitudinal position.

[0016] Preferably, the inner wall of the tower is provided with three groups of bearing seats distributed in a circular array, a screw with relatively distributed outer wall threads is rotatably installed inside the bearing seat, a threaded slider 1 is installed on the outer wall thread of the screw, which slides through the first stroke groove and is connected to the inner wall of the first stroke ring, and a threaded slider 2 is installed on the outer wall thread of the screw, which slides through the second stroke groove and is connected to the inner wall of the second stroke ring. The bearing seat supports the upper and lower ends and the center section of the screw, the threaded slider 1 slides inside the first stroke groove to obtain a sliding guide, and is pushed by the threads of the outer wall of the screw, the threaded slider 2 slides inside the second stroke groove to obtain a sliding guide, and is pushed by the threads of the outer wall of the screw, and because the threads of the outer wall of the screw are relatively distributed, the threaded slider 1 and the threaded slider 2 can move away from each other or move relative to each other.

[0017] Preferably, the inner wall of the tower is provided with a gear ring, the outer wall of the screw is sleeved with a driven gear meshing with the gear ring, the inner wall of the tower is fixed with a motor, and the output end of the motor is provided with a driving gear meshing with the gear ring. When the driving gear rotates, it pushes the gear ring, driving the gear ring to push the driven gear, thereby causing the screw to rotate synchronously in the same direction.

[0018] Preferably, the outer wall of the threaded slider 1 is provided with a stroke plate 1 which is slidably mounted on the outer wall of the tower and corresponds to the stroke groove 1, and the outer wall of the threaded slider 2 is provided with a stroke plate 2 which is slidably mounted on the outer wall of the tower and corresponds to the stroke groove 2. After the threaded slider 1 slides and resets inside the stroke groove 1, the stroke groove 1 is shielded by the stroke plate 1, and after the threaded slider 2 slides and resets inside the stroke groove 2, the stroke groove 2 is shielded by the stroke plate 2, so as to prevent rainwater and foreign objects from entering the tower through the stroke groove 1 and the stroke groove 2.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the wind turbine generator set of the present invention is maintained, the maintenance personnel climb up to the top of the tower. At this time, the top cover moves longitudinally and moves out of the outer side of the upper end of the adjustment plate. The screw rotates to apply extrusion force to the threaded slider 1 and the threaded slider 2. The extrusion force applied to the threaded slider 1 acts on the travel ring 1, and the extrusion force applied to the threaded slider 2 acts on the travel ring 2. Through the threads relatively distributed on the outer wall of the screw, the threaded slider 1 and the threaded slider 2 move away from each other. The shear arm 1 and the shear arm 2 installed by shearing rotate through the central axis. The shear arm 1 and the shear arm 2 are gradually unfolded, and the stored air cushion is unfolded to form a bowl-shaped sleeve on the outer side of the machine tower. When the maintenance personnel look down, what they directly see is the unfolded air cushion, forming a visual platform in the air, which relieves the psychological pressure of fear, anxiety, etc. of the maintenance personnel;

[0021] At the same time, gas is input into the air cushion to make it inflate. Maintenance personnel who accidentally fall during high-altitude operations will be caught by the bowl-shaped air cushion, providing additional safety protection for the maintenance personnel and avoiding casualties caused by direct falls. The safety of wind turbines during maintenance is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The protective structure 200 includes a fixed ring 204 sleeved on the outer wall of the machine tower 101, a travel ring 1 201 sleeved on the outer side of the machine tower 101 and located below the fixed ring 204, a lower rotating seat 211 fixed on the outer wall of the travel ring 1 201 and distributed in a circular array, an upper rotating seat 210 fixed on the outer wall of the fixed ring 204 and distributed in a circular array, a shear arm 1 202 rotatably installed inside the lower rotating seat 211, a shear arm 203 rotatably installed inside the upper rotating seat 210 and with one end located inside the shear arm 1 202, an air cushion 205 fixed between the shear arm 1 202 and the shear arm 203, a travel groove 1 213 opened inside the machine tower 101 and distributed in a circular array, a regulating pump 207 fixed on the inner wall of the top cover 313 and provided with two groups of air cushions 205 connected through hoses, and a central shaft 209 rotatably installed at the center of the shear arm 1 202 and at one end of the shear arm 203;

[0049] The air cushion 205 is hollow inside, and is provided with a plurality of mounting holes 206 distributed in a circular array inside, and the inner walls of the mounting holes 206 are connected by the air cushion 205;

[0052] The wind turbine comprises a wind turbine body 100, a protective structure 200, a storage structure 300 and a driving structure 400.

[0053] The wind turbine body 100 includes a tower 101;

[0054] The protective structure 200 includes a fixed ring 204 sleeved on the outer wall of the machine tower 101, a travel ring 1 201 sleeved on the outer side of the machine tower 101 and located below the fixed ring 204, a lower rotating seat 211 fixed on the outer wall of the travel ring 1 201 and distributed in a circular array, an upper rotating seat 210 fixed on the outer wall of the fixed ring 204 and distributed in a circular array, a shear arm 1 202 rotatably installed inside the lower rotating seat 211, a shear arm 203 rotatably installed inside the upper rotating seat 210 and with one end located inside the shear arm 1 202, an air cushion 205 fixed between the shear arm 1 202 and the shear arm 203, a travel groove 1 213 opened inside the machine tower 101 and distributed in a circular array, a regulating pump 207 fixed on the inner wall of the top cover 313 and provided with two groups of air cushions 205 connected through hoses, and a central shaft 209 rotatably installed at the center of the shear arm 1 202 and at one end of the shear arm 203;

[0055] The air cushion 205 is hollow inside, and is provided with a plurality of mounting holes 206 distributed in a circular array inside, and the inner walls of the mounting holes 206 are connected by the air cushion 205;

[0056] During maintenance at height, the hydraulic rod 310 controls the lifting of the top cover 313. During maintenance, the top cover 313 moves up to expose the adjustment plate 303, and the protective structure 200 is started, driving the shear arm 1 202 rotatably mounted on the travel ring 1 201 and the shear arm 203 rotatably mounted under the fixed ring 204 to unfold around the central axis 209, thereby mobilizing the air cushion 205 to unfold. The hollow design allows it to expand quickly through inflation, and the surface mounting hole 206 balances the internal and external air pressure to prevent the air cushion 205 from deforming or tearing in a strong wind environment. The air supply pump provides power for the inflation of the air cushion 205, and the air pump is used for rapid exhaust to ensure that the air cushion 205 can flexibly adjust the inflation volume to meet the needs of different maintenance scenarios. The unfolded air cushion 205 surrounds the machine tower 101 in a bowl shape, providing visual shielding for maintenance personnel and reducing the fear of looking down from a high altitude. At the same time, the physical existence of the air cushion 205 can accommodate people who accidentally fall and provide a safety buffer.

[0057] The regulating pump 207 includes an air suction pump and an air supply pump. The suction end of the air suction pump is connected to the air cushion 205 through a hose, and the output end of the air supply pump is connected to the air cushion 205 through a hose. A connecting piece 208 connected to the outer wall of the upper end of the air cushion 205 is provided at the top of the shear arm 202;

[0058] A travel groove is provided inside the shear arm 1 202, the central axis 209 is located inside the travel groove, and one end of the shear arm 203 is located inside the travel groove;

[0059] During maintenance at height, the hydraulic rod 310 controls the lifting of the top cover 313. During maintenance, the top cover 313 moves up to expose the adjustment plate 303, and the protective structure 200 is started, driving the shear arm 1 202 rotatably mounted on the travel ring 1 201 and the shear arm 203 rotatably mounted under the fixed ring 204 to unfold around the central axis 209, thereby mobilizing the air cushion 205 to unfold. The hollow design allows it to expand quickly through inflation, and the surface mounting hole 206 balances the internal and external air pressure to prevent the air cushion 205 from deforming or tearing in a strong wind environment. The air supply pump provides power for the inflation of the air cushion 205, and the air pump is used for rapid exhaust to ensure that the air cushion 205 can flexibly adjust the inflation volume to meet the needs of different maintenance scenarios. The unfolded air cushion 205 surrounds the machine tower 101 in a bowl shape, providing visual shielding for maintenance personnel and reducing the fear of looking down from a high altitude. At the same time, the physical existence of the air cushion 205 can accommodate people who accidentally fall and provide a safety buffer.

[0060] The hollow design allows it to expand quickly through inflation, and the surface mounting hole 206 balances the internal and external air pressure to prevent the air cushion 205 from being deformed or torn in a strong wind environment. The air supply pump provides power for the inflation of the air cushion 205, and the air extraction pump is used for rapid exhaust to ensure that the air cushion 205 can flexibly adjust the inflation volume. Through the sliding cooperation between the walking groove and the central axis 209, multi-stage expansion and folding can be achieved. When expanded, a stable triangular support structure is formed to improve the load-bearing capacity of the air cushion 205 platform. The bidirectional thread design of the screw 404 enables the threaded slider 1 408 and the threaded slider 2 409 to move synchronously in opposite directions, ensuring the symmetry and stability of the shear arm expansion process:

[0061] Maintenance personnel need to work at a height of tens of meters and lack effective anti-falling measures. The unfolded air cushion 205 forms an annular buffer platform. If a person falls, the buffering effect of the air cushion 205 can buy time for rescue and reduce the degree of injury. Accidentally falling people can be received by the air cushion 205. After inflation, the air cushion 205 forms a flexible receiving platform, which absorbs the impact force of the fall to the greatest extent and significantly reduces the risk of casualties. Looking down from a high altitude can easily cause fear and anxiety, leading to operational errors or decreased efficiency. After the air cushion 205 is unfolded, it forms a visual blocking platform, which reduces the sense of height when looking down and relieves psychological pressure.
