Description

Technical Field

[0001] This invention relates to the field of wind power tower maintenance equipment technology, specifically to a wind power tower inspection and maintenance equipment suitable for wind farms. Background Technology

[0002] As a clean and renewable green energy source, wind energy occupies an important position in the global energy structure transformation. The large-scale construction and efficient and stable operation of wind farms are the core links in promoting the development of renewable energy. As the core support carrier of wind turbine units, wind power towers integrate key systems such as electrical control, power conversion, communication, and safety protection. These systems are located in many key positions such as the bottom of the tower, nacelle, and hub, and are the foundation for ensuring normal power generation, power regulation, safe shutdown, and data transmission of wind turbines. As the wind power industry develops towards large capacity, intelligence, and intensification, the operation and maintenance management system of wind farms is becoming increasingly sophisticated. Regular inspections, condition monitoring, fault diagnosis, and component replacement of wind turbine towers have become crucial for ensuring the long-term reliable operation of wind farms, improving power generation efficiency, and extending the service life of turbine units. To adapt to the complex equipment layout inside wind turbine towers and the harsh outdoor operating environment, related maintenance equipment is gradually evolving towards integration, standardization, and protection. Among them, cabinet-structured maintenance equipment, with its high space utilization, good protection performance, high integration, and ease of deployment and operation, is widely used in various onshore and offshore wind farms. Existing wind power tower maintenance equipment, such as the wind power tower maintenance equipment disclosed in announcement number CN222436522U, can prevent workers from suffering heatstroke due to sun exposure during the maintenance of wind power towers, and further improve the safety of workers during work. However, the aforementioned existing technologies cannot be used to build a working platform, which means that staff do not have a convenient platform to operate during maintenance and repair, thus hindering their operation. In addition, existing technology uses locks on storage boxes to prevent tools from being lost during use. While the locks prevent tools from falling out of the storage box during transportation, the staff needs to unlock the locks to open the storage box, making it too cumbersome and not conducive to improving work efficiency. Therefore, there is a need for wind turbine tower inspection and maintenance equipment suitable for wind farms to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a wind turbine tower maintenance and repair device suitable for wind farms, in order to solve the problems mentioned in the background art that existing wind turbine tower maintenance and repair devices cannot build a working platform and that the use of tools in the storage box is cumbersome.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A wind turbine tower maintenance and repair device suitable for wind farms includes a main cabinet and a secondary cabinet connected to it via hinges. Both the main and secondary cabinets are equipped with casters on their lower surfaces. Drawers are movably connected to both the main and secondary cabinets, with raised strips on both sides of each drawer. Each raised strip has a limit hole, and through holes extending to the outside of the raised strip are located on both the upper and lower sides of the limit hole. Limit rods are installed inside both the main and secondary cabinets at positions corresponding to the drawers, and these limit rods extend movably into the corresponding limit holes. The limit rods have a T-shaped structure, and their ends... The sliding passage has two corresponding through holes. A platform assembly is provided between the upper ends of the main cabinet and the secondary cabinet, and a splicing assembly is provided between the lower ends of the main cabinet and the secondary cabinet. The platform assembly includes stepped upper surfaces on the main cabinet and the secondary cabinet, and extension plates are axially connected to the stepped upper surfaces on both the main cabinet and the secondary cabinet. The splicing assembly includes an arc-shaped strip fixedly connected to the lower side of the secondary cabinet. The stepped upper surfaces on both the main cabinet and the secondary cabinet limit the drawer through pneumatic limiting assemblies, and the pneumatic limiting assemblies include piston grooves provided on the stepped upper surfaces of the main cabinet and the secondary cabinet.

[0005] Furthermore, the platform component also includes a receiving groove on the lower surface of each extension plate, and a support plate is connected to one end of the receiving groove on the upper shaft. Support grooves are provided on the sides of the main cabinet and the secondary cabinet, and the two support grooves are arranged in a one-to-one correspondence with the two support plates.

[0006] Moreover, the extension plate has an arc-shaped structure, and the step height of the stepped upper surface on the main cabinet and the secondary cabinet matches the thickness of the extension plate.

[0007] Moreover, the lower end of the support plate and the support groove are both right-angled triangular prism structures, and the size of the lower end of the support plate and the support groove are consistent.

[0008] Furthermore, the splicing assembly also includes an arc-shaped groove on the main cabinet, and a piston chamber is provided at the inner top of the arc-shaped groove. A limit piston rod is seamlessly slidably connected to the inner side of the opening end of the piston chamber, and a spring is provided between the limit piston rod and the inner end of the piston chamber.

[0009] Furthermore, the end of the limiting piston rod that extends into the arc-shaped groove is a smooth spherical structure, and a slider is provided at the opening end of the arc-shaped groove. A sliding groove is provided on the inner arc surface of the arc-shaped groove, and the sliding groove and the slider are engaged and slidably connected.

[0010] Furthermore, the pneumatic limiting assembly also includes piston holes provided on the inner sides of both the main cabinet and the auxiliary cabinet, and a piston block is seamlessly slidably connected to the inner side of the opening end of the piston hole, and a stop block is fixedly connected to the end of the piston block that extends out of the piston hole.

[0011] Furthermore, the pneumatic limiting assembly also includes a piston plate seamlessly slidably connected to the inner side of the upper opening of each piston groove, and springs are equally spaced between the lower end of the piston plate and the inner bottom end of the piston groove. The upper end of the piston plate seamlessly extends through the opening end of the piston groove, and an air guide channel is provided between the lower end of the piston plate and the opening end of the piston groove, penetrating the piston hole. All piston holes on the main cabinet are interconnected, and all piston holes on the auxiliary cabinet are also interconnected. A through hole between adjacent piston holes is provided between the piston block and the inner end of the piston hole, and the air guide channel is also provided between the piston block and the inner end of the piston hole.

[0012] Furthermore, the piston groove on the main cabinet is also connected to the piston chamber through an air guide channel, and the air guide channel is also located between the lower end of the piston plate and the opening end of the piston groove.

[0013] The beneficial effects of this invention are as follows: 1. The wind power tower maintenance and repair equipment of the present invention, applicable to wind farms, provides a temporary working platform for staff, which helps them work. In addition, the pneumatic limit components prevent the drawers from sliding out during transportation, thus preventing the loss of tools inside. When in use, the drawers can be pulled out directly for easy access to the tools inside, thereby improving the work efficiency of the staff.

[0014] 2. The TMS target localization method for depression based on symptom improvement network guided by the present invention involves rotating two extension plates and rotating a support plate so that the lower end of the support plate is engaged in the corresponding support groove, thereby placing the two extension plates on the same plane as the upper surfaces of the main cabinet and the auxiliary cabinet. This forms a temporary working plane through the two extension plates and the upper surfaces of the main cabinet and the auxiliary cabinet, facilitating the work of the staff.

[0015] 3. The TMS target localization method for depression based on symptom improvement network guidance of the present invention, before the extension plate rotates, the action of spring two will cause the stop block to restrict the movement of the rear end of the drawer. In addition, the limiting piston rod will be locked into the slide groove under the action of spring one, thereby ensuring stable splicing of the main cabinet and the auxiliary cabinet. This prevents the drawer from sliding out during transportation, thus preventing the loss of tools inside. It also ensures that the main cabinet and the auxiliary cabinet will not rotate relative to each other during transportation. After the maintenance equipment is transported to the use position, the piston plate on the main cabinet is pressed. This allows the gas in the piston chamber to be extracted, thereby compressing the spring and moving the limiting piston rod into the piston chamber. This, in turn, allows the arc-shaped strip to move outward from the arc-shaped groove, enabling the main cabinet and the auxiliary cabinet to rotate relative to each other. This facilitates the subsequent construction of a temporary work platform. Furthermore, after the extension plate rotates, both piston plates are compressed, which extracts the gas in the piston hole. This allows the piston block to move into the piston hole, thus removing the block's restriction on the rear end of the drawer. At this point, workers can easily pull out the drawer and access the tools inside. Attached Figure Description

[0018] The present invention will now be described in more detail through specific embodiments. These embodiments are intended to help better understand and explain the present invention and are illustrative in nature, and do not constitute any limitation on the scope of protection of the present invention.

[0019] For an equipment for the inspection and maintenance of wind turbine towers in wind farms, please refer to [link / reference]. Figures 1-7 The system includes a main cabinet 1 and a secondary cabinet 2 connected to it by hinges. Both the main cabinet 1 and the secondary cabinet 2 are equipped with casters 6 on their lower surfaces. Both the main cabinet 1 and the secondary cabinet 2 have drawers 4 that can be moved through them. Both sides of the drawers 4 are provided with raised strips. The raised strips are provided with limit holes 24. Both the upper and lower sides of the limit holes 24 are provided with through holes 25 that extend to the outside of the raised strips. The interior of the main cabinet 1 and the secondary cabinet 2 are provided with limit rods 10 at positions corresponding to the drawers 4. The limit rods 10 can be moved into the corresponding limit holes 24. The limit rods 10 have a T-shaped structure and their ends slide through the two corresponding through holes 25. A platform assembly is provided between the upper ends of the main cabinet 1 and the secondary cabinet 2. The platform assembly includes stepped upper surfaces on the main cabinet 1 and the secondary cabinet 2. Both stepped upper surfaces on the main cabinet 1 and the secondary cabinet 2 are axially connected to extension plates 3.

[0020] The platform components also include receiving grooves 7 on the lower surface of each extension plate 3, with a support plate 8 connected to one end of the receiving groove 7. Support grooves 9 are provided on the sides of the main cabinet 1 and the secondary cabinet 2, and the two support grooves 9 correspond one-to-one with the two support plates 8. The extension plate 3 has an arc-shaped structure, and the step height of the stepped upper surface on the main cabinet 1 and the secondary cabinet 2 matches the thickness of the extension plate 3. The lower end of the support plate 8 and the support groove 9 are both right-angled triangular prism structures, and the structural size of the lower end of the support plate 8 and the support groove 9 matches.

[0021] according to Figures 1-2 as well as Figures 4-7 When in use, press the piston plate 18 on the main cabinet 1 to make the piston plate 18 in the piston groove 17 on the main cabinet 1 move down, and then draw the gas in the piston chamber 13 through the air guide channel 16. After the gas in the piston chamber 13 is extracted, the limiting piston rod 14 connected to it will gradually move to its inner end, thereby compressing the spring 15. After the limiting piston rod 14 moves to the inner end of the piston chamber 13, causing the limiting piston rod 14 to disconnect from the slide groove 11, the arc strip 5 can slide in the arc groove 12, thereby enabling the main cabinet 1 to rotate relative to the auxiliary cabinet 2. After the main cabinet 1 and the auxiliary cabinet 2 are rotated until the slider slides to the limit in the slide groove 11, rotate the two extension plates 3 and rotate the support plate 8 in the receiving groove 7 on the lower surface of the extension plate 3. After the support plate 8 is rotated out of the receiving groove 7, its lower end is inserted into the corresponding support groove 9. At this time, the upper surfaces of the two extension plates 3 will be at the same level as the upper surfaces of the main cabinet 1 and the secondary cabinet 2. Thus, a temporary working platform can be formed by the upper surfaces of the main cabinet 1 and the secondary cabinet 2 and the upper surfaces of the two extension plates 3, which helps the staff to operate tools on it.

[0022] To address the issue that traditional wind turbine tower maintenance equipment requires clips on storage boxes to prevent tool loss and thus hinder easy and quick tool retrieval, the following technical solution is provided: A splicing assembly is installed between the lower ends of the main cabinet 1 and the auxiliary cabinet 2. This assembly includes an arc-shaped strip 5 fixedly connected to the lower side of the auxiliary cabinet 2. The stepped upper surfaces of both the main cabinet 1 and the auxiliary cabinet 2 are pneumatically positioned to limit the drawer 4. The pneumatically positioned components include piston grooves 17 located on the stepped upper surfaces of both the main cabinet 1 and the auxiliary cabinet 2.

[0023] The splicing assembly also includes an arc-shaped groove 12 provided on the main cabinet 1, and a piston chamber 13 is provided at the inner top of the arc-shaped groove 12. A limiting piston rod 14 is seamlessly slidably connected to the inner side of the opening end of the piston chamber 13, and a spring 15 is provided between the limiting piston rod 14 and the inner end of the piston chamber 13. The end of the limiting piston rod 14 that extends into the arc-shaped groove 12 is a smooth spherical structure, and a slider is provided at the opening end of the arc-shaped groove 12. A sliding groove 11 is provided on the inner arc surface of the arc-shaped groove 12, and the sliding groove 11 is engaged and slidably connected with the slider.

[0024] The pneumatic limiting assembly also includes piston holes 21 provided on the inner sides of both the main cabinet 1 and the auxiliary cabinet 2, with a piston block 22 seamlessly slidably connected to the inner side of the opening end of the piston hole 21. A stop block 23 is fixedly connected to the end of the piston block 22 extending out of the piston hole 21. The pneumatic limiting assembly also includes a piston plate 18 seamlessly slidably connected to the inner side of the opening at the upper end of each piston groove 17, with springs 19 evenly spaced between the lower end of the piston plate 18 and the inner bottom end of the piston groove 17. The upper end of the piston plate 18 seamlessly extends through the opening end of the piston groove 17, and the lower end of the piston plate 18 is seamlessly slidably connected to the inner side of the piston groove 17. A second air guide channel 20 is provided between the open ends of 7, which penetrates the piston hole 21. All piston holes 21 on the main cabinet 1 are interconnected, and all piston holes 21 on the auxiliary cabinet 2 are also interconnected. A through hole between adjacent piston holes 21 is provided between the piston block 22 and the inner end of the piston hole 21. The second air guide channel 20 is also provided between the piston block 22 and the inner end of the piston hole 21. The piston groove 17 on the main cabinet 1 is also connected to the piston chamber 13 through the first air guide channel 16. The first air guide channel 16 is also provided between the lower end of the piston plate 18 and the open end of the piston groove 17.

[0025] according to Figure 3 as well as Figures 6-9 When in use, the piston plate 18 extends above the piston groove 17 under the action of the second spring 19, so that the stop block 23 can keep the drawer 4 in a limited position, thereby preventing the drawer 4 from sliding out when transporting the wind power tower maintenance equipment, which can also prevent the tools in the drawer 4 from being lost. In addition, during this process, the limiting piston rod 14 is stably connected in the slide groove 11 due to the action of the first spring 15, thereby preventing the main cabinet 1 and the auxiliary cabinet 2 from rotating relative to each other, thus facilitating the overall transportation of the main cabinet 1 and the auxiliary cabinet 2. When the extension plate 3 rotates, it will press against the piston plate 18, thereby causing the piston plate 18 to move into the piston groove 17 and compressing the spring 19. During the process, the gas in the piston hole 21 will be drawn into the piston groove 17 through the second air guide channel 20, thereby causing the stop block 23 to move towards the piston hole 21, so that the stop block 23 will gradually no longer obstruct the sliding of the drawer 4. In other words, after the temporary work platform is set up, the staff can easily pull out drawer 4 to access the tools inside.

[0026] Although the embodiments and accompanying drawings of this invention are disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, changes, and modifications can be made without departing from the basic spirit and scope of this invention and its appended claims. Therefore, the scope of protection of this invention is not limited to the content shown in the embodiments and drawings.
