Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation. More specifically, the present invention relates to a wind power generation device. Background Art

[0002] The principle of wind power generation is to use the wind to drive the rotation of the windmill blades, and then increase the rotation speed through a speed increaser to prompt the generator to generate electricity. According to the current windmill technology, a breeze speed of about three meters per second (the degree of a gentle breeze) can start generating electricity. Wind power generation is forming a boom in the world because wind power generation does not require the use of fuel and does not produce radiation or air pollution.

[0003] The wind power generation device includes an equipment platform, a wind turbine disposed on the equipment platform and drivingly connected to the internal electrical components of the equipment platform, and a tower barrel for supporting the equipment platform. The equipment platform serves as an operating platform for maintenance workers to stand on. To ensure the efficiency of wind power generation, the height of the tower barrel is generally about 120 meters. The equipment platform is at a relatively high height and the ambient temperature is relatively low, resulting in easy icing on the equipment platform. The existing wind power generation devices do not have the function of cleaning the ice layer on the surface of the equipment platform. However, the icing equipment platform surface cannot provide a safe standing platform for maintenance workers, resulting in the lack of safety guarantee for maintenance workers during the maintenance process.

[0052] In the description of the present invention, the orientation or positional relationship indicated by terms such as "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0053] As Figures 1-7 shown, the present invention provides a wind power generation device, which includes a tower barrel 1 provided on a base 11, an equipment platform 3 provided on the top of the tower barrel 1, and a wind turbine blade 2 provided at one end of the equipment platform 3. The transmission shaft 21 of the wind turbine blade 2 is connected to a generator provided in the equipment platform 3; it further includes an anti-slip mechanism, which includes:

[0054] A fixed plate 41, which is horizontally provided inside the equipment platform 3;

[0055] A movable plate 42, which is horizontally provided inside the equipment platform 3 and is located directly above the fixed plate 41;

[0056] Multiple groups of movable columns 43, which are arranged at intervals along the length direction of the equipment platform 3 ( Figure 2 as shown, the direction parallel to the screen is the width direction of the equipment platform, and the direction perpendicular to the screen is the length direction of the equipment platform). Each group of movable columns 43 includes multiple movable columns 43 arranged at intervals along the width direction of the equipment platform 3. The upper end of each movable column 43 is located above the movable plate 42, and the lower end vertically passes through the movable plate 42 and the fixed plate 41 and extends below the fixed plate 41; a first spring 44 is sleeved on the movable column 43. Each first spring 44 is located between the movable plate 42 and the fixed plate 41. The upper end of the first spring 44 is fixedly connected to the outer wall of the movable column 43, and the lower end is fixedly connected to the fixed plate 41; the movable plate 42 and the fixed plate 41 do not limit the up and down movement of each movable column 43;

[0057] A plurality of first rotating shafts 45 are provided. One first rotating shaft 45 is correspondingly arranged directly below each group of movable columns 43. Each first rotating shaft 45 extends horizontally along the width direction of the equipment table 3. Both ends of the first rotating shaft 45 are rotatably connected to the inner wall of the equipment table 3. A plurality of eccentric wheels 46 are provided on one side of the first rotating shaft 45. One eccentric wheel 46 is correspondingly arranged for each movable column 43. The diameters of any two adjacent eccentric wheels 46 are not equal;

[0058] Wherein, each first spring 44 is arranged such that when the first spring 44 is in a natural elongation state and the first rotating shaft rotates until the eccentric wheel is at the bottom of the first rotating shaft, the movable column 43 is directly above the first rotating shaft 45 and the movable column 43 does not interfere with the first rotating shaft 45, and at this time, the distance between the center of each eccentric wheel 46 and the axis of the corresponding first rotating shaft 45 is greater than the distance between the movable column 43 and the axis of the corresponding first rotating shaft 45.

[0059] In the above technical solution, the present invention provides an anti-slip mechanism in the wind power generation equipment, which improves the friction force when maintenance workers stand on the equipment table for equipment maintenance, and can also break and clean the ice layer on the equipment table, ensuring the safety and reliability during the maintenance by maintenance workers.

[0060] As Figure 1 、 7 shown, a plurality of movable columns are arranged on the top surface of the equipment table. The movable columns are connected to the fixed plate by springs. When the foot steps on the equipment table, the movable column contacted by the sole of the foot moves downward under the action of the human gravity. The plane formed by the plurality of movable columns will form a groove according to the shape of the maintenance worker's foot. As Figure 7 shown, the friction force between the foot and the top surface of the equipment table is increased, avoiding the dangerous accident of the maintenance worker falling due to foot slipping and unstable standing. When walking on the equipment table, the foot is lifted, and the downwardly recessed movable column automatically moves upward and returns to its position under the action of the first spring. The foot takes a step forward, steps down, and a groove matching the foot shape can be formed again, ensuring the safety of the entire process of the maintenance worker walking on the equipment table;

[0061] Furthermore, in freezing weather, before maintenance workers step onto the equipment platform, they can rotate the first rotating shaft to drive the eccentric wheel thereon to rotate. During the rotation of the eccentric wheel, it can push the corresponding movable column upward. Under the elastic restoring force of the first spring, the movable column moves downward, that is, the rotation of the first rotating shaft can drive the movable column to make reciprocating up and down movements. During the up and down movement of the movable column, the ice layer can be broken; in order to improve the ice-breaking efficiency, in this technical solution, the diameters of any two adjacent eccentric wheels are set to be unequal, so that the heights of the adjacent two movable columns moving up and down are inconsistent, which can exert a pulling and breaking force on the ice layer and accelerate the ice-breaking speed; preferably, the arrangement of multiple eccentric wheels on any two adjacent first rotating shafts can also be staggered, which can further improve the ice-breaking efficiency.

[0062] In another technical solution, for the wind power generation equipment, when the first spring 44 is in the natural elongation state, the part above the movable plate 42 is the first part, the part between the movable plate 42 and the fixed plate 41 is the second part, and the part below the fixed plate 41 is the third part;

[0063] A fixing ring 431 is rotatably sleeved on the second part of each movable column 43 through a bearing, and the upper end of each first spring 44 is fixedly connected to the corresponding fixing ring 431; when the movable column rotates around its own axis, the fixing ring does not rotate, and when the movable column moves up and down along the axis, it can drive the fixing ring to move up and down;

[0064] A threaded sleeve 47 is sleeved on the second part of each movable column 43, which is located above the fixing ring. External threads that can be threadedly rotatably connected to the threaded sleeve are provided on the second part and the third part of the movable column 43. The threaded sleeve is connected to the fixed plate through a pair of connecting rods 432; preferably, when the first spring is in the natural elongation state (starting state), the threaded sleeve is located at the position in contact with the movable plate and the threaded sleeve is located immediately above the thread turn on the movable column, that is, the threaded sleeve is not threadedly connected to the movable column; the threaded sleeve is connected to the fixed plate through the connecting rod, so that the threaded sleeve remains stationary; the threaded sleeve and the pair of connecting rods do not interfere with the up and down movement of the fixing ring and the first spring, and the pair of connecting rods can be respectively arranged on both sides of the fixing ring;

[0065] A plurality of grooves 48 are circumferentially spaced on the third part of each movable column 43. Each groove 48 is a strip-shaped structure extending in the vertical direction. A stirring rod 49 is correspondingly arranged in each groove 48. The upper end of each stirring rod 49 is hinged to the corresponding groove 48, and the stirring rod 49 can be completely accommodated in the corresponding groove 48.

[0066] In the above technical solution, the present invention hinges a plurality of stirring rods on the movable column, which can drive the stirring rods to make centrifugal rotation when the movable column moves up and down relative to the movable plate, thereby increasing the stirring amplitude of the ice layer and improving the ice-breaking efficiency;

[0067] Take Figures 2-5 as an example for detailed description: Figure 2 This is the state of the equipment before de-icing operation. In the cold winter, an ice layer appears on the equipment table. When it is necessary to de-ice the ice layer on the equipment table, rotate the first rotating shaft. During the process of driving the protruding part of the eccentric wheel to move to the upper part ( Figure 4 as shown), the eccentric wheel will push the movable column upward. When the eccentric wheel moves to the lower part along with the rotation of the first rotating shaft ( Figure 2 as shown), under the action of the first spring, the movable column drives the movable column to move downward. In this way, the rotation of the first rotating shaft drives the reciprocating up and down movement of the movable column;

[0068] During the process that the eccentric wheel pushes the movable column upward, the movable column moves upward relative to the movable plate and the threaded sleeve. When the movable column moves upward a little distance, the thread rings on the movable column are screwed with the thread rings on the inner wall of the threaded sleeve. When the movable column continues to move upward, the movable column can rotate relative to the threaded sleeve and around its own axis. The movable column moves upward in a spiral rotation. During the process that the movable column rotates upward, the stirring rod hinged on the movable column unfolds under the centrifugal force (as Figure 4 shown). The movable column is pushed to the highest position. As the first rotating shaft continues to rotate, the height of the eccentric wheel gradually becomes smaller. Under the action of the first spring, when the movable column drives the movable column to move downward, the movable column can rotate relative to the threaded sleeve and around its own axis (in the opposite direction to the upward rotation of the movable column). The movable column moves downward in a spiral rotation. The stirring rod hinged on the movable column will also unfold under the centrifugal force. The unfolded stirring rod can greatly stir the ice layer, improving the ice-breaking efficiency. After the ice-breaking operation is completed, all the first rotating shafts rotate back to the starting position, the movable column returns to its position under the action of the spring, the threaded sleeve is disengaged from the external thread on the movable column, and multiple stirring rods rotate back to the inside of the groove under their own gravity.

[0069] In another technical solution, for the wind power generation equipment, when the first spring 44 is in the natural elongation state, the top of each movable column 43 is flush with the top of one side of the equipment table 3;

[0070] The movable plate 42 is slidably connected with the inner wall of the equipment table 3 in the vertical direction; at least one first telescopic rod 5 is provided between the movable column 43 and the fixed plate 41;

[0071] The wind power generation equipment further includes a cleaning mechanism, which includes:

[0072] A water storage tank 61 is provided on one side of the equipment table 3. The top of the water storage tank 61 is open and flush with the top of one side of the equipment table 3. Overflow ports 611 are respectively provided at both ends of the water storage tank 61. The water storage tank 61 is communicated with the water supply tank of the cleaning mechanism of the wind turbine blades 2 through a water guide pipe.

[0073] A filter screen 62 is internally connected to the inside of the water storage tank 61. One side of the filter screen 62 is connected to the water storage tank

[0074] 61, and the other side extends obliquely downward away from the equipment table 3. The other side of the filter screen 62 is located above the overflow port 611. An electric heating block is arranged on the filter screen to heat the broken ice cubes and melt them into water.

[0075] A storage bin 63 is provided on the side of the water storage tank 61 away from the equipment table 3. The water storage tank 61

[0076] is communicated with the storage bin 63 through a material guide port 631. The material guide port 631 is located above the other side of the filter screen 62.

[0077] A cleaning box 64 is vertically arranged between the storage bin 63 and the base 11. The cleaning box 64 is communicated with the storage bin 63 through a material guide pipe 632. A door body 641 that can be opened and closed is provided at the lower part of the cleaning box 64.

[0078] A push plate 65 is vertically arranged on the other side of the equipment table 3. The bottom edge of the push plate 65 is flush with the top of one side of the equipment table 3. The push plate 65 is connected to the inner wall of the other side of the equipment table 3 through a second telescopic rod. The second telescopic rod extends horizontally along the width direction of the equipment table.

[0079] In the above technical solution, the present invention discloses a cleaning mechanism, which can clean the ice layer broken on the tabletop of the equipment table and other garbage. The movable plate is arranged as a structure that can move up and down. The movable plate can be driven by the extension of the first telescopic rod to move to a position flush with the top of the movable column and the top of one side of the equipment table. The movable plate and the top of the movable column form a plane flush with the top of one side of the equipment table. Subsequently, driven by the second telescopic rod, the push plate is driven to move along the width direction of the equipment table (as Figure 6 shown), and the push plate moves from the other side of the equipment table to one side of the equipment table ( Figure 6When moving from right to left, the push plate can push the crushed ice cubes and other garbage on the plane formed by the movable plate and the top of the movable column into the water storage tank. Under the heating effect of the electric heating block on the filter net, the ice cubes are melted into water, which falls into the water storage tank through the mesh holes on the filter net. The solid garbage on the filter net moves along the inclined filter net to the storage box and then moves into the cleaning box through the guide pipe. The cleaner can open the door at the lower part of the cleaning box to regularly clean the garbage in the cleaning box, realizing the cleaning of the ice cubes and other garbage on the equipment table;

[0080] After the ice cubes and other garbage are cleaned up, under the contraction effect of the second telescopic rod, the push plate is moved to the starting position (the position closely attached to the inner wall on the other side of the equipment table). Under the contraction effect of the first telescopic rod, the movable plate is moved downward to the starting position, and the top surface of the equipment table returns to the rough surface protruding from multiple movable columns.

[0081] When the first rotating shaft rotates in a state where it does not interfere with any movable column (non-ice removal operation state), as the starting state for the cleaning mechanism to start operating, the movable plate is moved upward. At this time, the movable column does not interfere with the up and down movement of the movable plate, that is, from Figure 2 to Figure 6 This state is the operation process of the cleaning mechanism. After the cleaning operation is completed, the push plate and the movable plate are moved to the starting position, and it returns to Figure 2 the state shown.

[0082] The ice cube melted water or rainwater collected in the water storage tank can be used for cleaning the wind turbine blades. Specifically, the existing technology can be used to connect the water storage tank to the water supply tank of the cleaning mechanism of the wind turbine blades through a water guide pipe. The cleaning mechanism here is the existing technology and will not be elaborated here. The present invention collects the ice cube melted water in the water storage tank and utilizes it for cleaning the wind turbine blades, improving the resource utilization rate; an overflow port is provided on the water storage tank. When there is more water collected in the water storage tank, the water inside the water storage tank is discharged in time. Preferably, the overflow port can be connected to the underground drainage system through a drainage pipe.

[0083] In another technical solution, the wind power generation equipment further includes a transmission mechanism, which includes:

[0084] Multiple first gear disks 71, one first gear disk 71 is fixedly sleeved at one end of each first rotating shaft 45, and any two adjacent first gear disks 71 are meshed with each other; multiple first gear disks can realize mutual transmission;

[0085] A first bevel gear 72, which is fixedly sleeved on the transmission shaft 21;

[0086] A second rotating shaft 73, which is horizontally arranged inside the equipment table 3, and the second rotating shaft 73 is parallel to the first rotating shaft 45;

[0087] The second bevel gear 74 is fixedly sleeved on one end of the second rotating shaft 73 and meshes with the first bevel gear 72;

[0088] The second gear disk 75 is fixedly sleeved on the other end of the second rotating shaft 73;

[0089] The third rotating shaft 76 is arranged parallel to the second rotating shaft 73 and is located between the second rotating shaft 73 and the plurality of first rotating shafts 45. The third rotating shaft 76 is connected to the outer wall of one side of the equipment table 3. The third rotating shaft 76 can horizontally move along its own axis direction and can rotate relative to the equipment table around its own axis;

[0090] The third gear disk 77 is fixedly sleeved on the third rotating shaft 76. The third gear disk 77 can be synchronously meshed with the second gear disk 75 and one of the first gear disks 71. All the first gear disks, second gear disks, third rotating shafts and third gear disks are arranged on the other side of the equipment table, (as Figure 2 、 4 、6, 7 show that all the first gear disks, second gear disks, third rotating shafts and third gear disks are arranged on the right side, and the water storage tank, the material storage tank and the cleaning tank are all arranged on the left side);

[0091] In the above technical solution, the present invention discloses a transmission mechanism, which realizes the rotation of the drive shaft to drive the rotation of all the first rotating shafts through gear transmission. Specifically, the rotation of the drive shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, further drives the second rotating shaft to rotate, the rotation of the second rotating shaft drives the second gear disk to rotate, and a third gear disk is arranged between the second gear disk and one of the first gear disks. When ice removal operation is required (the first rotating shaft needs to rotate to push the movable column to move up and down reciprocally), the third gear disk can be synchronously meshed with the second gear disk and one of the first gear disks, thereby driving the rotation of all the first gear disks, further driving the rotation of all the first rotating shafts, and the rotation of the first rotating shaft drives the movable column to move up and down reciprocally, so as to break the ice layer on the tabletop of the equipment table; when ice removal operation is not required (the first rotating shaft does not need to rotate), the third gear disk moves to a position where it is not in contact with the second gear disk and one of the first gear disks; the horizontal movement of the third gear disk is realized by the horizontal movement of the third rotating shaft along its own axis direction.

[0092] In another technical solution, for the wind power generation equipment, the third rotating shaft 76 is connected to the equipment table 3 through a sleeve 81. One end of the sleeve 81 is rotatably connected to the outer wall of the equipment table 3, and the other end is coaxially sleeved outside the third rotating shaft 76. The sleeve can rotate relative to the equipment table around its own axis. On both sides of the inner wall of one end of the sleeve 81, an electromagnet 82 is respectively arranged;

[0093] One end of the third rotating shaft 76 is connected to the inner wall of one end of the sleeve 81 through a second spring 83; iron sliders 84 are respectively arranged on both sides of the third rotating shaft 76, and each slider 84 is slidably connected to the inner wall of the sleeve 81 along the axial direction of the third rotating shaft 76, and each slider 84 is arranged corresponding to an electromagnet 82 along the axial direction of the third rotating shaft 76.

[0094] In the above technical solution, the present invention discloses the connection relationship between the third rotating shaft and the equipment table. The third rotating shaft is connected to the equipment table through the sleeve to realize rotation around its own axis. The third rotating shaft and the sleeve are slidably connected horizontally along the axial direction, and are controlled by an electromagnet, an iron block and a second spring. When the electromagnet is not energized, the second spring is in a natural elongation state, and the distance between the slider on the third rotating shaft and the electromagnet is the largest. At this time, the third gear disk does not interfere with the second gear disk and one of the first gear disks. When ice removal operation needs to be performed on the equipment table, the electromagnet is energized, and the electromagnet generates a magnetic suction force on the iron slider, driving the third rotating shaft to move towards the direction close to the equipment table, and then driving the third gear disk to move horizontally towards the direction close to the equipment table. When the slider is in magnetic contact with the electromagnet, both sides of the third gear disk are synchronously engaged with the second gear disk and one of the first gear disks. The rotation of the second gear disk drives the rotation of the third gear disk, and then drives the rotation of the first gear disk, finally realizing the rotation of all the first rotating shafts around their own axes; after the ice removal operation is completed, the electromagnet is powered off, the magnetic attraction between the electromagnet and the slider is released, and the slider moves horizontally away from the equipment table under the action of the second spring, and then drives the third rotating shaft to move away from the equipment table, thereby driving the third gear disk to move to the starting position (the third gear disk does not interfere with the second gear disk and one of the first gear disks).

[0095] In another technical solution, for the wind power generation equipment, the first telescopic rod 5 and the second telescopic rod are both electric telescopic rods, and the first telescopic rod 5, the second telescopic rod and the electromagnet 82 are all driven by the generator. The first telescopic rod and the second telescopic rod are set as electric telescopic rods, which improves the automation degree of the equipment. The wind energy of the wind turbine blades is converted into electric energy and stored through the generator, and then the electric energy stored by the generator is used to drive the telescopic movement of the first telescopic rod and the second telescopic rod, and the energization of the electromagnet, ensuring the normal operation of the first telescopic rod, the second telescopic rod and the electromagnet.

[0096] In another technical solution, for the wind power generation device, the number of teeth of the second gear disc 75 is several times that of the third gear disc 77, and the number of teeth of the third gear disc 77 is several times that of the first gear disc 71. The second gear disc is preferably driven to rotate by a transmission shaft. When it is necessary to de-ice the equipment platform, the third gear disc is adjusted to be synchronously engaged with one of the first gear discs and the second gear disc. The second gear disc drives the third gear disc and the first gear disc to rotate, so that all the first rotating shafts rotate. The number of teeth of the three gear discs is preferably such that the number of teeth of the second gear disc is the largest and the number of teeth of the first gear disc is the smallest, which can increase the rotation frequency of the first rotating shaft and thus improve the de-icing efficiency.

[0097] In another technical solution, for the wind power generation device, the tower barrel 1 has a frustum structure with a smaller upper part and a larger lower part; a manhole 12 is provided at the lower part of the tower barrel 1. Providing a manhole at the lower part of the tower barrel facilitates maintenance workers to enter for inspection and maintenance.

[0098] As Figures 1-2 shown in the starting state of the present invention (before the maintenance worker climbs onto the equipment platform and no ice-breaking operation has been carried out), each first spring is in a natural elongation state. The upper end of the movable column is above the movable plate, and the lower end is below the fixed plate. Each stirring rod is vertically and completely accommodated in the corresponding groove, and the push plate is located at a position near the inner wall on the other side of the equipment platform; the second spring is in a natural elongation state, the slider is not in contact with the electromagnet, and the third gear disc does not interfere with the second gear disc and one of the first gear discs; the eccentric wheel on the first rotating shaft is located on its lower side and does not interfere with the movable column;

[0099] When an ice-breaking operation is carried out, the electromagnet is energized, and the electromagnet magnetically attracts the slider. The third rotating shaft horizontally moves to a position where the third gear disc is engaged with the second gear disc and one of the first gear discs. The first rotating shaft rotates around its own axis under the transmission of the transmission mechanism, and then drives a plurality of eccentric wheels to rotate, thereby driving the movable column to move up and down reciprocally. During the movement, the stirring rod on the movable column unfolds;

[0100] After the ice-breaking is completed, the electromagnet is powered off. Under the action of the second spring, the third rotating shaft and the third gear disc return to their original positions, the first rotating shaft stops rotating, and the first rotating shaft returns to its starting position. Under the action of the first spring, the movable column returns to its starting position;

[0101] When performing the cleaning operation, start the first telescopic rod and push the movable plate upward (the stirring rod on the movable plate can freely pass through the perforations on the movable plate) to a height flush with the top of one side of the equipment table. The top of the movable plate and multiple movable columns form a flat surface without holes. Then start the second telescopic rod and push the push plate along the width direction of the equipment. The push plate can push the garbage on the flat surface formed by the top of the movable plate and multiple movable columns into the water storage tank. In case of snowy or icy weather, start the electric heating block to heat the broken ice cubes, and the melted ice water is collected into the water storage tank. The remaining garbage is moved into the storage bin and then moves into the cleaning box through the guide pipe. The cleaner regularly opens the door to clean the garbage. After the cleaning operation is completed, start the second telescopic rod to contract and pull the push plate back to the starting position. Then start the first telescopic rod to contract and lower the movable plate back to the starting position.

[0102] As Figure 7 shown, when the maintenance worker steps onto the equipment table, the feet step on the equipment table, and multiple movable columns automatically form grooves consistent with the shape of the feet. When the movable columns move downward from the starting position, the thread sleeve does not contact the external thread on the movable column, that is, the movable column only moves vertically downward without rotating around its own axis, which can ensure the comfort of the maintenance worker when stepping on.

[0103] The equipment quantity and processing scale described here are used to simplify the description of the present invention. The application, modification, and variation of the present invention are obvious to those skilled in the art.

[0104] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated and described examples here.
