A repairing and reinforcing device and method applied to wind power engineering

Abstract

This invention discloses a repair and reinforcement device and method for wind power engineering, belonging to the technical field of wind turbine maintenance equipment. It includes a base and a solution tank placed on the base. A coating assembly is fixedly mounted on a movable base. The coating assembly is used to evenly coat the solution in the solution tank onto a fiberglass cloth. A movable brush roller rotates after contacting the blades. A pump delivers the evenly stirred polyester liquid in the solution tank to a first elastic pad. Then, a cut fiberglass cloth is placed on the polyester liquid. During the return stroke, the ratchet on the first telescopic rod rotates due to the meshing connection of the rack and pinion. The rotating ratchet causes the upper magnetic block to intermittently approach the lower magnetic block on the flyboard. Since the upper and lower magnetic blocks have the same magnetism at their proximal ends, the lower magnetic block is pushed away when they approach each other, causing the flyboard to continuously drive the second elastic pad to pat the fiberglass cloth, expelling internal air bubbles.

Description

Technical Field

[0001] This invention relates to the field of wind turbine repair equipment technology, and in particular to a repair and reinforcement equipment and method for wind power projects. Background Technology

[0002] As a clean energy source, wind power has significant economic, social, and environmental benefits, promotes sustainable economic development, and plays a positive role in driving rapid local economic development. It has become a "new force" in the development of the power industry.

[0003] However, after a period of use, wind turbines inevitably develop damage on their blades. In order to avoid negatively impacting power generation efficiency, the blades need to be repaired in a timely manner.

[0004] Repairing the blades requires grinding the damaged areas and then re-bonding new fiberglass cloth. However, air bubbles can easily form between the layers of fiberglass cloth during bonding. These air bubbles need to be repaired during the second grinding process, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that air bubbles are easily generated between the layers of fiberglass cloth during bonding in the prior art, and the air bubbles need to be repaired during secondary polishing, which is time-consuming and labor-intensive. The invention proposes a repair and reinforcement device and method for wind power projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A repair and reinforcement device for wind power projects includes a base, a support frame welded to the base, a slide rail welded to the support frame, a slider assembled inside the slide rail, a horizontal plate fixedly mounted on the slider, connecting seats fixedly mounted on both sides of the horizontal plate along its length, a drive rod assembly installed between the two connecting seats, and a movable seat mounted on the drive rod assembly; a first motor fixedly mounted on one of the connecting seats, the output end of the first motor being connected to the drive rod assembly via a coupling; and further includes: a solution tank placed on the base; and a coating assembly fixedly mounted on the movable seat, the coating assembly being used to evenly coat the solution in the solution tank onto a fiberglass cloth.

[0008] For bonding fiberglass cloth, preferably, the coating assembly includes: a hollow protective plate, on which a first telescopic rod is fixedly installed, the fixed end of the first telescopic rod being fixedly connected to a movable seat, and a brush roller being rotatably installed inside the opening of the hollow protective plate; a conveying pipe is fixedly connected between the hollow protective plate and the solution tank, and a pump body is fixedly installed on the conveying pipe; and a conveying port communicating with the hollow interior is opened on the inner wall of the hollow protective plate.

[0009] To increase the contact area between the brush roller and the blade, the brush roller is further wrapped with a first elastic pad, which is adhered to the brush roller with adhesive tape.

[0010] To further prevent excess polyester liquid from flowing out, brushes are fixedly installed on both sides of the hollow protective plate, and the brushes abut against the first elastic pad.

[0011] To further agitate the fiberglass cloth and remove air bubbles, the system includes: a fly plate with a second telescopic rod fixedly mounted on it, the fixed end of which is fixedly connected to a movable base; a second elastic pad on the side of the fly plate away from the movable base; a ratchet rotatably mounted on the fixed end of the first telescopic rod, with an upper magnetic block arranged in a ring fixedly mounted on the side of the ratchet near the fly plate; a lower magnetic block corresponding to the upper magnetic block fixedly mounted on the fly plate, the upper and lower magnetic blocks having the same magnetism at their near ends; and a rack on a horizontal plate, which engages with the ratchet when rotating in the opposite direction.

[0012] To further control the pump's operation, the horizontal plate has an installation groove, and the inner walls of the groove on both sides of the installation groove have sliding grooves. Sliding pins are slidably installed in the sliding grooves, and the rack is fixedly installed between the sliding pins on both sides. A first spring is fixedly connected between the sliding pins and the bottom surface of the sliding groove. Electrode plates that can contact each other are fixedly installed between the rack and the bottom surface of the installation groove, and the output end of the electrode plate is connected to the pump body.

[0013] To improve the drying speed of the polyester liquid, an airbag is fixedly connected between the fly plate and the second elastic pad, and a nozzle is fixedly installed on the airbag. The second elastic pad has a through hole that can accommodate the nozzle. A heating chamber communicating with the airbag is opened inside the fly plate, and a heating element is fixedly installed on the wall of the heating chamber.

[0014] To further improve the heat exchange effect, a partition is fixedly installed inside the heating chamber, which divides the heating chamber into a serpentine path.

[0015] To further prevent the polyester liquid on the fiberglass cloth from being sucked into the airbag, an air intake pipe connected to the heating chamber is fixedly installed on the fly plate. Both the air intake pipe and the nozzle are equipped with one-way valves, and the two one-way valves open in opposite directions.

[0016] A repair and reinforcement method for wind power projects, the operation steps are as follows:

[0017] Step 1: Grind the damaged surface of the blade until the undamaged surface is exposed;

[0018] Step 2: Cut a piece of fiberglass cloth slightly larger than the damaged area based on its size and depth;

[0019] Step 3: Prepare the polyester solution and pour it into a container;

[0020] Step 4: First, apply polyester liquid to the sanding surface and cover it with fiberglass cloth. Then, roll the fiberglass cloth until it is soaked through with polyester liquid.

[0021] Step 5: Pat the surface of the fiberglass cloth until there are no air bubbles inside.

[0022] Compared with the prior art, the present invention provides a repair and reinforcement device and method for wind power projects, which has the following beneficial effects:

[0023] 1. This equipment is used for repair and reinforcement in wind power projects. Initially, the moving brush roller rotates after contacting the blade. The pump body transports the evenly stirred polyester liquid in the solution tank to the hollow protective plate through the conveying pipe, and it falls from the conveying port on the hollow protective plate onto the first elastic pad. The first elastic pad is made of rubber and has good deformation ability, which can evenly coat the uneven parts of the blade with polyester liquid. Then, the cut glass fiber cloth is covered on the polyester liquid. During the return stroke, the ratchet on the first telescopic rod rotates due to the meshing connection of the rack and pinion. The rotating ratchet drives the upper magnetic block to intermittently approach the lower magnetic block on the fly plate. Since the magnetism of the upper and lower magnetic blocks is the same at the close ends, the lower magnetic block is pushed away when they approach each other. The thrust acts on the fly plate, causing the fly plate to continuously drive the second elastic pad to beat the glass fiber cloth and expel the internal air bubbles.

[0024] 2. This equipment is used for repair and reinforcement in wind power projects. During the application of polyester liquid by the brush roller, the outer arc surface of the ratchet teeth conforms to the tooth surface of the rack and will not mesh together. The ratchet pushes the rack into the mounting groove until the two electrode plates contact each other and generate current to make the pump work. During the pressing of the fiberglass cloth, the rack resets and embeds into the ratchet, causing the ratchet to rotate. The two motor plates no longer contact each other, and the pump stops working, preventing excess polyester liquid from flowing onto the fiberglass cloth and improving the repair time.

[0025] 3. This equipment is used for repair and reinforcement in wind power projects. During the process of the fly plate driving the second elastic pad to continuously beat the fiberglass cloth, the airbag is also continuously squeezed and released. When the airbag is squeezed, the air inside is ejected from the through hole through the nozzle. When the airbag is released, the negative pressure generated inside draws the outside air into the heating chamber through the air inlet pipe. Because the partition divides the heating chamber into a serpentine path, it increases the time that the air is stored in the fly plate, which improves the heat exchange effect. After the hot air is ejected from the nozzle, it accelerates the drying of the polyester liquid. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example 1:

[0038] Reference Figures 1-8 A repair and reinforcement device for wind power projects includes a base 1, a support frame 2 welded to the base 1, a slide rail 3 welded to the support frame 2, the slide rail 3 extending perpendicularly to the base 1, a slider 301 assembled inside the slide rail 3, and a horizontal plate 4 fixedly mounted on the slider 301. Connecting seats 5 are fixedly mounted on both sides of the horizontal plate 4 along its length, and a drive rod assembly 6 is installed between the two connecting seats 5. A movable seat 7 is assembled on the drive rod assembly 6. A first motor 8 is fixedly mounted on one connecting seat 5, and the output end of the first motor 8 is connected to the drive rod assembly 6 through a coupling. The device also includes a solution tank 9, which is placed on the base 1. In this embodiment, a third motor 901 is installed on the solution tank 9, and the output end of the third motor 901 extends into the interior of the solution tank 9 and is fixedly connected to a stirring paddle, which can stir the solution in the solution tank 9. A coating assembly is fixedly mounted on the movable seat 7 and is used to evenly coat the solution in the solution tank 9 onto a fiberglass cloth.

[0039] See Figures 1-3 and Figure 6 A second lead screw 302 is rotatably installed inside the slide rail 3. The upper end of the second lead screw 302 passes through the slide rail 3 and is connected to a second motor 303. A linear groove 304 is provided on the inner wall of the slide rail 3 to constrain the slider 301, so that the slider 301 can move linearly on the second lead screw 302 under the drive of the second motor 303.

[0040] participate Figures 1-3 The drive rod assembly 6 includes a guide rod 601 fixedly installed between two connecting seats 5 and a first lead screw 602 rotatably installed between the two connecting seats 5. The movable seat 7 is simultaneously mounted on the guide rod 601 and the first lead screw 602. During the operation of the first motor 8, the guide rod 601 can constrain the rotation of the movable seat 7 so that the movable seat 7 can only move linearly on the first lead screw 602.

[0041] It should be noted that the solution in solution tank 9 is a mixture of polyester liquid and 4%-5% coagulant. If the working environment temperature is low, a larger proportion of coagulant should be used.

[0042] See Figures 1-4 The coating assembly includes: a hollow protective plate 10, on which a first telescopic rod 11 is fixedly installed, the fixed end of the first telescopic rod 11 is fixedly connected to the movable seat 7, a brush roller 12 is rotatably installed inside the opening of the hollow protective plate 10, a first elastic pad 23 is wrapped on the brush roller 12, and the first elastic pad 23 is bonded to the brush roller 12 with adhesive tape; a conveying pipe 13 is fixedly connected between the hollow protective plate 10 and the solution tank 9, a pump body 1301 is fixedly installed on the conveying pipe 13, and a conveying port 1001 communicating with the hollow interior is opened on the inner wall of the hollow protective plate 10.

[0043] It should be noted that the first telescopic rod 11 includes a fixed end and a movable end. A second spring 1101 is sleeved on the movable end, and the preload of the second spring 1101 makes the first elastic pad 23 stick tightly to the blade.

[0044] See Figure 4 Furthermore, in order to prevent excessive polyester liquid from flowing out of the hollow protective plate 10, brushes 1002 are fixedly installed on both sides of the hollow protective plate 10. The brushes 1002 abut against the first elastic pad 23, and the brushes 1002 block the flow of polyester liquid and spread the polyester liquid on the surface of the first elastic pad 23 evenly when the brush roller 12 rolls.

[0045] See Figures 1-3 and Figure 5 and Figure 8 It also includes: a fly plate 14, on which a second telescopic rod 15 is fixedly installed, the fixed end of the second telescopic rod 15 is fixedly connected to the movable seat 7, and a second elastic pad 16 is provided on the side of the fly plate 14 away from the movable seat 7; a ratchet 17 rotatably installed on the fixed end of the first telescopic rod 11, on the side of the ratchet 17 near the fly plate 14, an upper magnetic block 18 arranged in a ring is fixedly installed, and a lower magnetic block 19 corresponding to the upper magnetic block 18 is fixedly installed on the fly plate 14, the upper magnetic block 18 and the lower magnetic block 19 have the same magnetism at their near ends; and a rack 20 provided on the horizontal plate 4, which can mesh with the rack 20 when the ratchet 17 rotates in the opposite direction.

[0046] With the above structure, the blade to be repaired is placed below the brush roller 12. The slider 301 can move linearly on the second screw 302 under the drive of the second motor 303 and gradually approach one side of the blade until the brush roller 12 contacts the blade. The first motor 8 is turned on. During the operation of the first motor 8, the guide rod 601 can constrain the rotation of the moving seat 7 so that the moving seat 7 can only move linearly on the first screw 602. After the moving brush roller 12 contacts the blade, it rotates. The pump body 1301 transports the polyester liquid that is stirred evenly in the solution tank 9 to the hollow guard plate 10 through the conveying pipe 13, and drops it from the conveying port 1001 on the hollow guard plate 10 onto the first elastic pad 23. The first elastic pad 23 is made of rubber and has good deformation ability, which can evenly coat the uneven parts of the blade with polyester liquid. Then, the cut glass fiber cloth is covered on the polyester liquid.

[0047] The first motor 8 rotates in the reverse direction to drive the moving seat 7 back. During the return journey, the ratchet 17 on the first telescopic rod 11 rotates due to the meshing connection of the rack 20. The rotating ratchet 17 drives the upper magnetic block 18 to intermittently approach the lower magnetic block 19 on the fly plate 14. Since the magnetism of the upper magnetic block 18 and the lower magnetic block 19 is the same at their close ends, the lower magnetic block 19 is pushed away when they approach each other. The thrust acts on the fly plate 14, causing the fly plate 14 to continuously drive the second elastic pad 16 to beat the fiberglass cloth and expel the internal air bubbles.

[0048] Example 2:

[0049] See Figures 1-8 The solution is basically the same as in Example 1, but the entire technical solution has been further optimized based on Example 1.

[0050] See Figure 1 and Figure 6 The specific implementation scheme for controlling the operation of the pump body 1301 has been added. An installation groove 401 is provided on the horizontal plate 4. A sliding groove 402 is provided on the inner side wall of the groove on both sides of the installation groove 401. A sliding pin 403 is slidably installed in the sliding groove 402. A rack 20 is fixedly installed between the sliding pins 403 on both sides. A first spring 404 is fixedly connected between the sliding pin 403 and the bottom surface of the groove 402. Electrode plates 21 that can contact each other are fixedly installed between the rack 20 and the bottom surface of the groove 401. The output end of the electrode plate 21 is connected to the pump body 1301.

[0051] With the above structure, during the application of polyester liquid by the brush roller 12, the outer arc surface of the ratchet 17 teeth will not mesh with the tooth surface of the rack 20, and the ratchet 17 will push the rack 20 into the mounting groove 401 until the two electrode plates 21 come into contact with each other and generate current to make the pump body 1301 work.

[0052] During the pressing of the fiberglass cloth, the rack 20 resets and engages with the ratchet 17, causing the ratchet 17 to rotate. The two electrode plates 21 no longer contact each other, and the pump body 1301 stops working, preventing excess polyester liquid from flowing onto the proportioning fiber cloth.

[0053] Example 3:

[0054] See Figures 1-8 The solution is basically the same as in Example 2, but the entire technical solution has been further optimized based on Example 2.

[0055] See Figure 5 The embodiment adds a specific implementation scheme to accelerate the drying of polyester liquid. An air bag 22 is fixedly connected between the fly plate 14 and the second elastic pad 16. A nozzle 2201 is fixedly installed on the air bag 22. The second elastic pad 16 has a through hole 1601 that can accommodate the nozzle 2201. A heating chamber 1401 communicating with the air bag 22 is opened inside the fly plate 14. A heating element is fixedly installed on the cavity wall of the heating chamber 1401. In this embodiment, the heating element is either an electromagnetic heating tube or an infrared heating element.

[0056] See Figure 5 A partition 1402 is fixedly installed inside the heating chamber 1401, which divides the heating chamber 1401 into a serpentine path.

[0057] See Figure 5 An air inlet pipe 1403 connected to the heating chamber 1401 is fixedly installed on the fly plate 14. Both the air inlet pipe 1403 and the nozzle 2201 are equipped with one-way valves, and the two one-way valves open in opposite directions.

[0058] With the above structure, as the fly plate 14 drives the second elastic pad 16 to continuously beat the fiberglass cloth, the airbag 22 is also continuously squeezed and released. When the airbag 22 is squeezed, the air inside is ejected from the through hole 1601 through the nozzle 2201. When the airbag 22 is released, the negative pressure generated inside draws outside air into the heating chamber 1401 through the air inlet pipe 1403. Since the partition 1402 divides the heating chamber 1401 into a serpentine path, it increases the time that the air is stored in the fly plate 14, thereby improving the heat exchange effect. After the hot air is ejected from the nozzle 2201, it accelerates the drying of the polyester liquid.

[0059] It should be noted that the output end of nozzle 2201 is located inside the second elastic pad 16 to avoid direct contact with the fiberglass cloth and to prevent clogging.

[0060] A repair and reinforcement method for wind power projects, the operation steps are as follows:

[0061] Step 1: Pre-treatment. Grind the damaged surface of the blade, and also grind the cracks caused by the damage, until the undamaged surface is exposed. Then grind the ground area smooth.

[0062] Step 2: Cut a piece of fiberglass cloth slightly larger than the damaged area based on its size and depth;

[0063] Step 3: Pour an appropriate amount of polyester liquid into solution tank 9, and add 4%-5% coagulant to solution tank 9. Driven by the third motor 901, the stirring paddle can stir the solution in solution tank 9.

[0064] Step 4: Place the blade to be repaired under the brush roller 12. The slider 301 can move linearly on the second screw 302 under the drive of the second motor 303 and gradually approach one side of the blade until the brush roller 12 contacts the blade. Turn on the first motor 8. During the operation of the first motor 8, the guide rod 601 can constrain the rotation of the moving seat 7 so that the moving seat 7 can only move linearly on the first screw 602. After the moving brush roller 12 contacts the blade, it rotates. The pump body 1301 transports the polyester liquid that is stirred evenly in the solution tank 9 through the conveying pipe 13 to the hollow guard plate 10, and drops from the conveying port 1001 on the hollow guard plate 10 onto the first elastic pad 23. The first elastic pad 23 is made of rubber and has good deformation ability, which can evenly coat the uneven parts of the blade with polyester liquid. Then, the cut glass fiber cloth is placed on the polyester liquid.

[0065] Step 5: The first motor 8 rotates in the reverse direction to drive the moving seat 7 back. During the return journey, the ratchet 17 on the first telescopic rod 11 rotates due to the meshing connection of the rack 20. The rotating ratchet 17 drives the upper magnetic block 18 to intermittently approach the lower magnetic block 19 on the fly plate 14. Since the magnetism of the upper magnetic block 18 and the lower magnetic block 19 is the same at their close ends, the lower magnetic block 19 is pushed away when they approach each other. The thrust acts on the fly plate 14, causing the fly plate 14 to continuously drive the second elastic pad 16 to beat the fiberglass cloth and expel the internal air bubbles.

[0066] Step 6: During the application of polyester liquid by the brush roller 12, the outer arc surface of the ratchet 17 teeth does not mesh with the tooth surface of the rack 20, and the ratchet 17 pushes the rack 20 into the mounting groove 401 until the two electrode plates 21 contact each other and generate current to make the pump body 1301 work; during the pressing of the fiberglass cloth, the rack 20 resets and embeds into the ratchet 17 to rotate the ratchet 17, the two electrode plates 21 no longer contact each other, the pump body 1301 stops working, and excess polyester liquid is prevented from flowing onto the fiberglass cloth;

[0067] Step 7: While the fly plate 14 drives the second elastic pad 16 to continuously beat the fiberglass cloth, the airbag 22 is also continuously squeezed and released under force. When the airbag 22 is squeezed, the air inside is ejected from the through hole 1601 through the nozzle 2201. When the airbag 22 is released, the negative pressure generated inside draws outside air into the heating chamber 1401 through the air inlet pipe 1403. Since the partition 1402 divides the heating chamber 1401 into a serpentine path, it increases the time that the air is stored in the fly plate 14, thereby improving the heat exchange effect. After the hot air is ejected from the nozzle 2201, it accelerates the drying of the polyester liquid.

[0068] 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.
