Description

Technical Field

[0001] This application relates to the field of wind power generation equipment, and more specifically, to an emergency power protection device for wind power generation equipment. Background Technology

[0002] Wind energy is currently the most technologically mature and readily available renewable and clean energy source for large-scale development. Its development provides a foundation for harmonious development between humanity and nature. However, because wind turbines operate in natural environments, they are inevitably affected by natural disasters.

[0003] For example, Chinese Patent Publication No. CN112145351A discloses the following technical solution: A wind power generation equipment protection device based on the Internet of Things (IoT), comprising a generator compartment, a drive shaft inserted into the right wall of the generator compartment, a drive gear sleeved on the right outer wall of the drive shaft, a transmission gear meshing on the outer wall of the drive gear, a generator fixedly connected to the left side of the transmission gear, a reduction gear sleeved on the left outer wall of the drive shaft, a reduction rod movably connected to the inner wall of the reduction gear, and a rack meshing on the outer wall of the reduction gear. This IoT-based wind power generation equipment protection device uses an electromagnetic sleeve to eject the internal rack, which drives the reduction gear to rotate. The reduction gear, through a guide groove on its front, allows the reduction rod, carrying a reduction plate, to engage with the drive shaft to reduce its speed, preventing excessive rotational speed of the drive shaft from damaging the generator and extending the service life of the wind power generation equipment.

[0004] The existing technology has the following problems: The above-mentioned device uses a slider to move the plug to the right to engage with the socket. When the slider is no longer pulled by the counterweight ball, the return spring extends and moves the slider to the right, disengaging the plug from the socket. After the plug and socket are engaged, the return spring pulls the vertically inserted plug out by applying a lateral force, which is very difficult. Even if it is pulled out, it will cause considerable friction. In addition, if the wind speed changes too quickly, the plug and socket will frequently engage and disengage, which is not only difficult to achieve in time, but also easy to cause short circuits.

[0014] The advantages of this application are:

[0015] (1) This application utilizes the centrifugal ball and linkage system to automatically activate the deceleration device when the wind speed is too high, thereby reducing the rotational speed of the drive shaft A and preventing damage to the wind turbine generator due to excessive rotational speed in strong wind conditions. This effectively extends the service life of the wind power generation device and avoids malfunctions. The sliding mechanism of the baffle allows the air intake pipe of the housing to open automatically in strong winds, enhancing airflow and optimizing power generation efficiency. It only opens in strong wind weather to ensure the stability of the system under normal weather conditions.

[0016] (2) This application effectively collects and filters rainwater by setting up a water collection component, ensuring that impurities in the rainwater do not enter the key components of the wind power generation device. Through the filter cover and scraper cleaning function, the internal water flow of the system is kept smooth, reducing the accumulation of dirt.

[0017] (3) By setting an adjustment component, this application can tilt the lightning rod at a certain angle during strong winds. Without affecting its lightning protection effect, the tilted state of the lightning rod is more wind-resistant than the vertical state because the force of the wind on it is reduced.

[0034] Example 1, please refer to Figures 1-5 This embodiment provides an emergency power protection device for a wind power generation device, including: a base 1; a support column 2, which is fixedly connected to the upper end of the base 1; a generator compartment 3, which is the core part of the entire wind power generation device. It contains a generator and converts wind energy into electrical energy through connection with drive shafts A51 and B53. The generator compartment 3 is fixedly connected to the upper end of the support column 2. The front end of the generator compartment 3 is provided with drive shaft A51, drive shaft B53, housing 52, and fan blades 54. A fixing ring 61 is fixedly sleeved on the outer wall of the drive shaft B53. A connecting rod A62 is hinged to the outer wall of the fixing ring 61. A centrifugal ball 63 is hinged to the other end of the connecting rod A62. A connecting rod B6 is hinged to the other side of the centrifugal ball 63. 4. A rotating ring 65 is hinged to the other end of the connecting rod B64. Air inlet pipes 66 are provided on both sides of the housing 52. A connecting ring 67 is fixedly connected to the outer wall of the rotating ring 65. A connecting rod A68 is fixedly connected to both sides of the connecting ring 67. A baffle 69 is fixedly connected to the outer wall of the connecting rod A68. The sliding function of the baffle 69 is to adjust the air inlet pipe 66 of the housing 52 so that it will only open in strong winds. A rotating disk 610 is rotatably connected inside the housing 52. A sliding groove 611 is provided on the side of the rotating disk 610. A roller 612 is slidably connected inside the sliding groove 611. A deceleration clamp 620 is provided outside the drive shaft A51. A hydraulic component for pushing the deceleration clamp 620 is provided on the side of the housing 52. The hydraulic components include a cylindrical hydraulic chamber 613, which is fixedly connected to the outer wall of the receiving box 52. A connecting pipe 616 is fixedly connected to the upper end of the cylindrical hydraulic chamber 613. A hydraulic rod A614 is slidably connected inside the cylindrical hydraulic chamber 613. An arc-shaped plate 615 is fixedly connected to the bottom of the hydraulic rod A614. An annular plate 618 is fixedly connected to the other end of the connecting pipe 616. An annular hydraulic chamber 617 is fixedly connected to the outer wall of the power generation chamber 3. The annular plate 618 is rotatably connected to the outer wall of the annular hydraulic chamber 617 and the connecting pipe 616 communicates with the annular hydraulic chamber 617. A hydraulic rod B619 is slidably connected inside the annular hydraulic chamber 617. The other end of the hydraulic rod B619 is fixedly connected to the deceleration clamp 620. Drive shaft A51 is fixedly connected to the outer wall of power generation chamber 3 and to the generator inside power generation chamber 3. Receiving box 52 is fixedly connected between drive shaft A51 and drive shaft B53. Fan blade 54 is fixedly connected to the other end of drive shaft B53. Connecting ring 67 is slidably connected to the outer wall of drive shaft B53. Spring 621 is fixedly connected between fixed ring 61 and rotating ring 65. Water collection assembly 7 is fitted to the outer wall of support column 2, and adjustment assembly 8 is fitted to the outer wall of power generation chamber 3.

[0035] In use, during strong winds, the fan blades 54 cause the drive shaft A51, housing 52, and drive shaft B53 to rotate at increased speeds. Consequently, the fixed ring 61, which is fitted onto the outside of drive shaft B53, also rotates faster. The connecting rod A62, hinged to it, then drives the centrifugal ball 63 to rotate. Due to the increased rotation speed, the centrifugal ball 63, under centrifugal force, causes the connecting rod A62 to open outwards. This, in turn, causes the rotating ring 65 to compress the spring 621 and move closer to the fixed ring 61 via the connecting rod B64. The rotating ring 65 then moves the connecting ring 67, causing the connecting rods A68 on both sides of the connecting ring 67 to move closer to the fixed ring 61. This allows the baffle 69 to slide from the inside of the air intake pipe 66 to the outside. Since the air intake pipe 66 rotates with the housing 52, when the baffle 69 releases its obstruction on one side of the air intake pipe 66, air enters the housing 52, driving the rotation... As the disk 610 rotates, the roller 612, which is slidably connected to the groove 611 on the side of the rotating disk 610, slides outward under the action of centrifugal force. During the rotation of the rotating disk 610, the roller 612 pushes the arc plate 615 closer to the inner wall of the receiving box 52. As a result, the hydraulic rod A614 at the upper end of the arc plate 615 slides into the cylindrical hydraulic chamber 613. The connecting pipe 616 drives the annular plate 618 to rotate, while transporting the hydraulic oil inside the cylindrical hydraulic chamber 613 to the inside of the annular hydraulic chamber 617. As a result, the hydraulic rod B619 slidably connected inside the annular hydraulic chamber 617 slides outward, thereby driving the deceleration clamp 620 to move towards the drive shaft A51 until it contacts the drive shaft A51. This decelerates the drive shaft A51, and consequently, the drive shaft B53, the receiving box 52, and the fan blades 54 also decelerate, preventing the drive shaft from rotating too fast and damaging the generator, and extending the service life of the wind power generation equipment.

[0036] Example 2, please refer to Figures 1-7Based on Embodiment 1, the water collection assembly 7 includes a movable ring 71, which is slidably connected to the outer wall of the drive shaft B53. A connecting rod B72 is fixedly connected to the bottom of the movable ring 71. A toothed plate 73 is fixedly connected to the outer wall of the connecting rod B72. A fixing plate 74 is fixedly connected to the outer wall of the support column 2. A collection hopper 75 is fixedly connected to the middle of the fixing plate 74. A filter cover 77 is fixedly connected to the upper end of the collection hopper 75 via a connecting shaft. The filter cover 77 is used to filter rainwater and prevent impurities from entering the system. A gear 78 is rotatably connected to the upper end of the fixing plate 74. A connecting rod C79 is fixedly connected to the upper end, and a scraper 710 is fixedly connected to the outer wall of the connecting rod C79. The scraper 710 is used to clean the surface of the filter cover 77 to prevent dust or debris from accumulating and affecting water flow. A limiting rod A716 is fixedly connected to the upper end of the collection hopper 75, and an L-shaped plate 711 is slidably connected to the outer wall of the limiting rod A716. A connecting cover 712 is fixedly connected to the upper end of the L-shaped plate 711, and a clearing rod 713 is fixedly connected to the outer wall of the connecting cover 712. The diameter of the clearing rod 713 matches the diameter of the filter holes of the filter cover 77, thereby allowing for better clearing of the filter holes. The toothed plate 73 meshes with the gear 78. A limiting rod B715 is fixedly connected to the outer wall of the support column 2, and a connecting rod B72 is slidably connected to the outer wall of the limiting rod B715. The setting of the limiting rod B715 can limit the movement range of the connecting rod B72, allowing it to move only horizontally.

[0037] In use, when it rains, the filter cover 77 filters the rainwater, and the filtered rainwater enters the collection hopper 75 for collection. Finally, the rainwater is sent to the cooling water tank inside the support column 2 through the conveying pipe at the bottom of the collection hopper 75. When the connecting ring 67 moves towards the fixed ring 61, it drives the moving ring 71 to move synchronously, which in turn drives the toothed plate 73 to move through the connecting rod B72. When the toothed plate 73 moves, the gear 78 meshing with it will rotate accordingly. Then the connecting rod C at the upper end of the gear 78 will rotate. 79 will also rotate, and the connecting rod C79 will drive the scraper 710 to clean the surface of the filter cover 77. When the connecting rod C79 moves to the lower end of the L-shaped plate 711, it will lift the L-shaped plate 711 to the upper end, so that the L-shaped plate 711 slides on the outer wall of the limiting rod A716. Then the connecting cover 712 fixedly connected to the upper end of the L-shaped plate 711 will move to the upper end, and the unblocking rod 713 at the upper end of the connecting cover 712 will move to the upper end, thereby filtering the filter holes of the filter cover 77.

[0038] Example 3, please refer to Figures 1-7Based on Embodiment 1, the adjusting component 8 includes a mounting block 81, which is fixedly connected to the outer wall of the power generation chamber 3. A mounting groove 82 is formed on the inner side of the mounting block 81. A mounting shaft 83 is rotatably connected to the inner wall of the mounting groove 82. A lightning rod 84 and a connecting block 85 are sleeved on the outer wall of the mounting shaft 83. A sliding shaft 86 is fixedly connected to the outer wall of the connecting block 85. A connecting rod D87 is fixedly connected to the upper end of the toothed plate 73. A moving plate 88 is fixedly connected to the outer wall of the connecting rod D87. A guide groove 89 is formed on the outer wall of the moving plate 88. The guide groove 89 extends downward at an incline, allowing the sliding shaft 86, which is slidably connected inside, to move downward during movement, thereby driving the mounting shaft 83 to rotate via the connecting block 85. The sliding shaft 86 is slidably connected inside the guide groove 89.

[0039] When in use, the movement of the toothed plate 73 indicates strong winds. The movement of the toothed plate 73 will cause the connecting rod D87 to move, which in turn will cause the moving plate 88 to move. The sliding shaft 86 will then slide along the guide groove 89, which will cause the mounting shaft 83 to rotate through the connecting block 85, thereby causing the lightning rod 84 to tilt at a certain angle.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
