Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind turbine assembly, in particular to a mountain wind farm wind turbine impeller assembly platform and its use method. BACKGROUND

[0002] Wind power generation, as a clean and renewable energy form, has been widely valued and applied worldwide. Its basic principle is to convert the kinetic energy of wind into electrical energy through wind turbine generators. This process is not only environmentally friendly and pollution-free, but also has the advantage of long-term sustainable use. However, the installation environment of wind power generation equipment is often complex and variable, especially in remote wild areas such as mountains, where the terrain conditions are complex and the roads are narrow, posing great challenges to equipment installation. Wind power generation equipment is usually set up in these areas to fully utilize abundant wind resources to meet power generation needs, but the complex terrain of remote wild areas, such as uneven ground and narrow roads, greatly increases the installation difficulty.

[0003] Currently, the assembly of wind turbine impellers relies on the construction of temporary assembly platforms on the installation site. These platforms are designed according to the site terrain and installation requirements to provide a stable and safe working environment. However, the assembly platforms in the prior art have significant defects. On the one hand, the temporary construction platform requires a large amount of time and manpower, resulting in slow construction progress, especially in areas such as forests where the installation space is limited, and the installation efficiency is even lower. For example, CN213572906U discloses a mountain wind farm wind turbine impeller assembly and hoisting platform. Although this platform adopts a modular design, it is fixedly connected by stacking multiple support platforms, forming an assembly platform of a certain height, and is equipped with auxiliary equipment such as climbing ladders, monitors and alarm devices, but in the complex terrain and limited space of forest environment, the construction and adjustment of the support platform still require more time and manpower, affecting the overall installation efficiency.

[0004] On the other hand, although the integrated platform solves the problem of repeated construction and removal, it is extremely inconvenient to transport due to the narrow roads in remote areas. For example, CN222650097U discloses a mountain wind farm wind turbine impeller assembly and hoisting platform. Although it sets multiple rows of inserted pegs at the bottom of the load-bearing table to enhance stability, the overall structure is extremely difficult to transport in remote and narrow road mountain wind farms, increasing transportation costs and time.

[0005] More importantly, existing assembly platforms suffer from shortcomings in adaptability and stability. Mountainous terrain is highly variable, with significant differences in terrain conditions at different locations. Existing platforms often struggle to adapt to various complex terrains, resulting in poor stability and safety hazards during use. Particularly in sensitive areas such as forests where ecological protection is crucial, platform construction may also damage surrounding vegetation, further limiting its application. While the CN213572906U platform possesses some height adjustment capabilities, its adjustment mechanism is relatively complex and lacks flexibility, making it difficult to quickly adapt to installation needs under different terrain conditions. Although the CN222650097U platform improves stability in soft soil through its stake design, the anchoring effect of the stake may be significantly reduced on hard ground or rocky terrain, limiting the platform's versatility across various terrain conditions.

[0006] Furthermore, the installation environment for wind turbine rotors is often limited by forest areas. For ecological protection reasons, trees around the installation area cannot be felled indiscriminately, resulting in limited ground installation space and further exacerbating the installation difficulty. To address this issue, existing technologies employ the method of erecting temporary assembly platforms in forests for wind turbine rotor assembly. However, while these temporary platforms can alleviate the problem of insufficient installation space to some extent, their construction and dismantling are time-consuming and labor-intensive, significantly impacting the overall efficiency of wind turbine rotor assembly.

[0007] The main problems and shortcomings can be summarized as follows: 1. Low installation efficiency: The setup and dismantling of temporary assembly platforms is cumbersome and requires a significant investment of manpower and time, severely impacting the installation efficiency of wind turbine rotors. This problem is particularly pronounced in complex terrain and limited space, such as in woodland environments.

[0008] 2. Transportation difficulties: While the integrated platform simplifies the setup and dismantling process, its large size makes transportation extremely inconvenient in remote, mountainous wind farms with narrow roads. This not only increases transportation costs but may also prevent the platform from reaching the designated installation location due to road conditions.

[0009] 3. Insufficient adaptability: Existing platform designs often fail to fully consider the special terrain conditions of mountain wind farms, such as slopes and uneven ground. This results in insufficient stability of the platform during installation and use, posing safety hazards, and also limits the platform's versatility and flexibility under different terrain conditions.

[0010] 4. Complex operation: Although some platforms have certain height adjustment functions, their adjustment mechanisms are complex and inconvenient to operate. In practical applications, professional personnel are required for operation and maintenance, increasing the cost and technical threshold of use.

[0011] In summary, the prior art has problems such as low installation efficiency, transportation difficulty, insufficient adaptability, and complex operation in the process of assembling the impeller of a wind turbine in a mountainous wind farm. To solve these problems, the present application proposes a new type of impeller assembly platform for wind turbines in mountainous wind farms, aiming to effectively solve the shortcomings of the prior art and improve the assembly efficiency and safety of the impeller of a wind turbine through innovative structural design and technical means. The platform is designed with foldable support structure and adjustable support structure, which realizes the rapid unfolding and contraction of the assembly platform, as well as stable support and horizontal adjustment under different terrain conditions. This innovation not only improves the assembly efficiency and safety, but also reduces the impact on the ecological environment, providing strong support for the installation of wind power equipment in complex terrain conditions. SUMMARY

[0012] The present application provides an impeller assembly platform for wind turbines in mountainous wind farms and its use method, which solves the technical problems in the process of assembling the impeller of a wind turbine in a mountainous wind farm. Specifically, in view of the problems of time-consuming platform construction, transportation inconvenience, poor adaptability, and insufficient stability of the impeller assembly platform for wind turbines in remote wild and complex terrain conditions in the prior art, the present application provides a new solution to overcome the limitations of low assembly efficiency, transportation difficulty, poor terrain adaptability, and insufficient stability in the prior art.

[0013] To achieve the above-mentioned objectives, the present application adopts the following technical solutions, The impeller assembly platform for wind turbines in mountainous wind farms comprises a frame, a rotating support connected to the side wall of the frame through a hinge, and a platform plate installed on the frame and the rotating support, forming a stable working surface for the assembly work of the impeller of a wind turbine.

[0014] The foldable support structure comprises a drive motor, a drive rod, a drive bevel gear, a driven bevel gear, a rotating lead screw, a moving block, and a support inclined rod. Specifically, the drive motor is fixed on the side wall of the frame, and its output end is fixedly connected with the drive rod. The other end of the drive rod is fixedly connected with the drive bevel gear. The drive bevel gear is meshed with the driven bevel gear, which is fixed on the rotating lead screw. The rotating lead screw is rotatably connected in the inner cavity of the frame, and the moving block is threadedly connected on it. The moving block is hinged to one end of the support inclined rod, and the other end of the support inclined rod is hinged to the side wall of the rotating support. When the drive motor works, the moving block moves on the rotating lead screw through the transmission of the drive rod, the drive bevel gear, the driven bevel gear, and the rotating lead screw, and then pushes or pulls the rotating support to rotate around the hinge through the support inclined rod, realizing the rapid folding and unfolding of the platform. This design greatly facilitates the transportation and installation of the platform, especially in narrow or complex terrain conditions, which can significantly reduce the installation time and labor cost.

[0015] Support adjustable structure: the foldable support structure is connected with a support adjustable structure, which includes a fixed sliding sleeve, a fixed housing, a rotating rod, an adjusting screw rod and a moving sliding sleeve. Specifically, the fixed sliding sleeve is fixed on the support inclined rod, and the moving sliding sleeve is slidably connected inside the fixed sliding sleeve. The bottom end of the moving sliding sleeve is fixed with a support foot for contacting the ground and providing stable support. The fixed housing is fixed on the side wall of the fixed sliding sleeve, and the rotating rod is rotatably connected inside the fixed housing. One end of the rotating rod extends to the outside of the fixed housing for manual operation, and the other end is fixedly connected with the adjusting screw rod. The adjusting screw rod is threadedly connected inside the moving sliding sleeve. When the rotating rod rotates, it drives the adjusting screw rod to rotate, thereby adjusting the relative position between the moving sliding sleeve and the fixed sliding sleeve, and realizing the precise adjustment of the height of the support foot. This design enables the platform to be accurately adjusted according to different terrain conditions, ensuring the stability and safety of the platform during use.

[0016] Auxiliary components: the side walls of the frame are also connected with a controller and a traction ring. The controller is used to control the working state of the drive motor, realizing the automatic folding and unfolding of the platform; the traction ring is convenient for remote control and transportation of the platform by external equipment (such as a tractor). At the same time, the inner cavity of the frame is connected with a storage battery, which provides stable power support for the electric components (such as drive motor, controller, etc.) on the platform.

[0017] Method for using the wind turbine blade assembly platform in mountain wind farm: In use, first, the platform is transported to the installation site of the mountain wind farm through the traction ring. Then, the drive motor is started by the controller, and the drive motor drives the moving block to move on the rotating screw rod through the transmission of the drive rod, drive bevel gear, driven bevel gear and rotating screw rod, and then drives the rotating support to rotate around the hinge through the support inclined rod, so that the platform is unfolded to the working state. Then, according to the terrain conditions on site, the rotating rod is manually rotated, the relative position between the moving sliding sleeve and the fixed sliding sleeve is adjusted by the adjusting screw rod, the support foot is in close contact with the ground, and the stability of the platform is ensured. Finally, the workers can assemble the wind turbine blades on the platform board. After assembly, the platform can be folded in the reverse order, which is convenient for transportation and storage.

[0018] The wind turbine blade assembly platform in mountain wind farm and the method for using the same provided by the application have the following beneficial effects: 1、The application effectively solves the technical problems of time-consuming construction, inconvenient transportation, poor adaptability and insufficient stability in the process of assembling wind turbine blades in mountain wind farms, and overcomes the limitations of low assembly efficiency, difficult transportation, poor terrain adaptability and insufficient stability in the prior art.

[0021] 4、The foldable support structure of the present application uses a driving motor to cooperate with a transmission structure, so that the volume of the platform is greatly reduced after folding, which is suitable for transportation on narrow roads in mountainous areas, and successfully solves the problem of inconvenient transportation of integrated platforms.

[0022] 5、The present application is different from the traditional temporary platform which is time-consuming and laborious to build and inconvenient to disassemble, and the integrated platform which is difficult to transport, the foldable support structure greatly facilitates the transportation of the device, improves the transportation efficiency, and reduces the loss and cost in the transportation process.

[0023] 6、The support adjustable structure of the present application can accurately adjust the platform according to different terrain conditions, ensure the stability and safety of the platform during use, and improve the reliability of the operation.

[0024] 7、The present application can independently adjust the height of each support leg with the help of the support adjustable structure, so that the platform can adapt to complex terrain in mountainous areas, ensure the stability and accurate leveling of the platform, and improve the operation safety and assembly precision.

[0025] 8、The support adjustable structure of the present application can manually and flexibly adjust the height of each support leg, so that the device is more stable when used in different mountainous terrain, and the platform level can also be conveniently adjusted, effectively solving the problem of inconvenient installation in complex mountainous terrain.

[0026] 9、The foldable support structure and the support adjustable structure of the present application work together, not only can quickly complete the platform contraction and expansion, shorten the construction and disassembly time, but also can flexibly adjust the support height according to the terrain, without the need for complex ground leveling operation, so that the platform is more convenient and efficient in use in mountain wind farms.

[0027] 10、The present application combines the foldable support structure and the support adjustable structure, improves the convenience of platform use, can quickly contract and expand the platform, and timely adjust the height of the support leg according to the terrain, and adapts to various complex environments.

DETAILED DESCRIPTION

[0036] The technical solutions in the present application will be further described below in combination with the drawings and examples: Example 1 This example provides a mountain wind farm wind turbine impeller assembly platform, which comprises a frame 1, a rotating support 2 is rotatably connected to the side wall of the frame 1 through a hinge, a platform plate 3 is installed on the frame 1 and the rotating support 2, a foldable support structure 4 is connected in the frame 1, a support adjustable structure 5 is connected to the foldable support structure 4, a controller 6 and a traction ring 7 are connected to the side wall of the frame 1, and a battery 8 is connected in the inner cavity of the frame 1.

[0037] In this example, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The foldable support structure 4 comprises a driving motor 401 connected to the support plate of the frame 1, a driving rod 402 connected to the driving end of the driving motor 401 through a shaft coupling, a driven bevel gear 404 connected to the other end of the driving rod 402 through a driving bevel gear 403, a rotating lead screw 405 connected to the center of the driven bevel gear 404, a moving sliding block 406 connected to the side wall of the rotating lead screw 405 in a symmetrical manner, a limiting sliding rod 407 connected to the moving sliding block 406, the two ends of the limiting sliding rod 407 being connected to the frame 1, a connecting link 408 connected to the side wall of the moving sliding block 406 in a symmetrical manner, a connecting plate 409 connected to the other end of the connecting link 408, a rotating support rod 410 connected to the other end of the connecting plate 409, a connecting plate 411 connected to the other end of the rotating support rod 410, a connecting link 412 connected to the other end of the connecting plate 411, the connecting link 412 being connected to the rotating support 2, a fixed link 413 connected to the bottom of the moving sliding block 406, a rotating pull rod 414 connected to the other end of the fixed link 413, a connecting seat 415 connected to the other end of the rotating pull rod 414, a connecting pull rod 416 connected to the connecting seat 415 in a symmetrical manner, a moving link 417 connected to the other end of the connecting pull rod 416, and a limiting sliding sleeve 418 connected to the side wall of the moving link 417 and the frame 1.

[0038] Based on the above structure and the connecting relationship thereof, the controller 6 sends a control signal to the driving motor 401 to control the driving motor 401 to operate. When the driving end of the driving motor 401 rotates, the driving rod 402, the driving bevel gear 403, the driven bevel gear 404 and the rotating lead screw 405 are synchronously rotated in sequence. Since the rotating lead screw 405 is composed of a left-handed screw rod and a right-handed screw rod, and is threadedly connected to the moving sliding block 406, when the rotating lead screw 405 rotates, the two groups of moving sliding blocks 406 move in opposite directions on the side wall of the rotating lead screw 405. At the same time, the limiting sliding rod 407 guides and limits the movement of the moving sliding block 406, ensuring that the moving sliding block 406 moves stably along a straight line.

[0039] During the movement of the moving sliding block 406, the connecting link 408 on the side wall thereof pushes the connecting plate 409 to move, the connecting plate 409 in turn drives the rotating support rod 410 to rotate, the rotating support rod 410 pulls the rotating support 2 to rotate around the hinge through the connecting plate 411 and the connecting link 412, so as to support open the platform plate 3 on the rotating support 2 and form a complete work platform surface.

[0040] At the same time, when the mobile slider 406 moves, the fixed connecting rod 413 at the bottom of the mobile slider 406 pulls the rotating pull rod 414 to move, the rotating pull rod 414 drives the connecting seat 415 to move, the connecting seat 415 drives the two groups of mobile connecting rods 417 to be spread apart along the connecting grooves of the limiting sliding sleeves 418 through the connecting rod 416, so that the support adjustable structure 5 is unfolded, and preparation is made for the support and leveling of the subsequent platform.

[0041] Further, the storage battery 8 is electrically connected with the controller 6 through wires to provide stable working power supply for the controller 6; and the driving motor 401 is electrically connected with the controller 6 through wires to ensure that the controller 6 can accurately control the start-stop and rotating speed of the driving motor 401.

[0042] The driving rod 402 is connected to the frame 1 through a bearing seat, and the driving rod 402 and the bearing seat are rotationally connected, which reduces the friction resistance when the driving rod 402 rotates, and ensures stable rotation of the driving rod 402; similarly, the rotating screw 405 is connected to the frame 1 through a bearing seat, and the rotating screw 405 and the bearing seat are rotationally connected, which ensures smooth and stable transmission of power of the rotating screw 405.

[0043] The connecting rod 408 and the connecting plate 409, the connecting plate 409 and the rotating support rod 410, the rotating support rod 410 and the connecting plate 411, and the connecting plate 411 and the connecting rod 412 are rotationally connected through rotating shafts, which ensures flexible transmission between the components, avoids damage of the components due to rigid connection, and ensures stability of the unfolding process of the rotating support 2.

[0044] The connecting rod 413 and the rotating pull rod 414, the rotating pull rod 414 and the connecting seat 415, the connecting seat 415 and the connecting rod 416, and the connecting rod 416 and the mobile connecting rod 417 are rotationally connected through rotating shafts, which enables the spreading process of the mobile connecting rod 417 to be coordinated with the unfolding process of the rotating support 2, realizes synchronous unfolding of the overall structure of the platform, and improves the platform building efficiency.

[0045] In the embodiment, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 7The support adjustable structure 5 comprises a fixed sliding sleeve 501 connected to one end of the moving connecting rod 417, a fixed shell 502 connected to the end face of the fixed sliding sleeve 501, a rotating rod 503 connected to the fixed shell 502, a knob 504 connected to one end of the rotating rod 503, an axle fixing device 505 connected to the sidewall of the fixed shell 502 and located on the cylindrical surface of the rotating rod 503, a connecting bevel gear 507 connected to the sidewall of the rotating rod 503 and located in the inner cavity of the fixed shell 502 through a connecting bevel gear 506, an adjusting screw rod 508 connected to the center of the connecting bevel gear 507, a moving sliding sleeve 509 connected to the sidewall of the adjusting screw rod 508 and located in the inner cavity of the fixed sliding sleeve 501, and a support plate 510 connected to the bottom of the moving sliding sleeve 509. Based on the above structure and the connection relationship thereof, when it is necessary to adjust the support height or the levelness of the platform, the staff can manually rotate the knob 504 to drive the rotating rod 503 to synchronously rotate. When the rotating rod 503 rotates, the connecting bevel gear 506 on the sidewall thereof will rotate synchronously. Since the connecting bevel gear 506 is in mesh with the connecting bevel gear 507, the connecting bevel gear 506 will drive the connecting bevel gear 507 to rotate, and the connecting bevel gear 507 will further drive the adjusting screw rod 508 at the center thereof to rotate.

[0046] Since the adjusting screw rod 508 is in threaded connection with the moving sliding sleeve 509, and the fixed sliding sleeve 501 plays a guiding role on the moving sliding sleeve 509 (the fixed sliding sleeve 501 is in sliding connection with the moving sliding sleeve 509), when the adjusting screw rod 508 rotates, the moving sliding sleeve 509 will move up and down along the inner cavity of the fixed sliding sleeve 501, so as to change the contact height of the support plate 510 with the ground. By respectively adjusting the support heights of the support adjustable structures 5, the whole platform can adapt to the complex terrain of the mountain, and the platform plate 3 can be kept in a horizontal state, so as to provide a stable and safe operation platform for the impeller assembly operation.

[0047] When the support height is adjusted in place, the rotating rod 503 can be fixed through the axle fixing device 505 to prevent the rotating rod 503 from accidentally rotating in the process of using the platform, so as to change the support height and further ensure the stability and safety of the platform.

[0048] Further, the rotating rod 503 is connected to the fixed shell 502 through a bearing seat and is in rotating connection with the bearing seat, which reduces the friction when the rotating rod 503 rotates, so that the staff can rotate the knob 504 more labor-savingly. The adjusting screw rod 508 is connected to the fixed shell 502 through a bearing seat and is in rotating connection with the bearing seat, which ensures that the adjusting screw rod 508 can stably rotate, so as to realize the smooth lifting of the moving sliding sleeve 509.

[0049] The workflow of the application: when using the mountain wind farm wind turbine impeller assembly platform, first check the battery 8 power, ensure that the device power supply is sufficient, then connect the device to the power supply, so that the device is in standby state. Through the traction device and the traction ring 7 on the side wall of the frame 1, the device is pulled to the designated impeller assembly position of the mountain wind farm.

[0050] After arriving at the designated position, the worker operates the controller 6 to send a start signal to the drive motor 401 to control the drive motor 401 to run. The drive end of the drive motor 401 rotates to drive the drive rod 402 to rotate, the drive rod 402 drives the drive bevel gear 403 to rotate, the drive bevel gear 403 drives the driven bevel gear 404 to rotate, and the driven bevel gear 404 drives the rotating lead screw 405 to rotate.

[0051] Since the rotating lead screw 405 is a combination structure of left and right rotation, and is threadedly connected with the moving slider 406, when the rotating lead screw 405 rotates, the two groups of moving sliders 406 move in opposite directions along the limiting sleeve 418. During the movement of the moving slider 406, on the one hand, the rotating support 2 is driven to rotate around the hinge by the connection link 408, the connection link plate 409, the rotating support rod 410, the connection link plate 411 and the connection link 412, the platform plate 3 on the rotating support 2 is opened, and a complete work platform is formed; on the other hand, the moving link 417 is driven to expand to both sides along the limiting sleeve 418 by the fixed link 413, the rotating pull rod 414, the connection seat 415, and the connection pull rod 416, so that the support adjustable structure 5 is synchronized to the position.

[0052] After the platform is expanded, the worker manually rotates the knob 504 of each support adjustable structure 5 according to the site terrain, adjusts the height of the moving sleeve 509 through the transmission of the rotating rod 503, the engagement bevel gear 506, the connecting bevel gear 507 and the adjusting lead screw 508, makes the support plate 510 closely contact with the ground, and assists observation through tools such as level, and ensures that the platform plate 3 is in a horizontal state. After adjustment, the rotating rod 503 is fixed by the shaft fixator 505 to prevent accidental change of the support height.

[0053] At this time, the platform is built, and the worker can perform the assembly work of the wind turbine impeller on the platform plate 3. After the impeller is assembled, the drive motor 401 is controlled to reverse by the controller 6, and the drive motor 401 drives the reverse movement of each transmission structure, so that the rotating support 2 is folded, and the moving link 417 is retracted, and finally the platform is restored to the folded state, so as to be transported to the next work site or stored.

[0054] The controller 6, the storage battery 8 and the driving motor 401 used in the present application are all known electrical devices and can be directly purchased on the market, and their structure, circuit and control principle are all known technologies, so the structure, circuit and control principle of the controller 6, the storage battery 8 and the driving motor 401 will not be described here.

[0055] Embodiment 2 In another preferred embodiment, based on the above-mentioned embodiment 1, the present embodiment provides a wind turbine impeller assembly platform for mountain wind farms, which mainly comprises a frame 1, a rotating support 2, a platform plate, a foldable support structure and a support adjustable structure.

[0056] The frame 1 is the main frame of the whole platform, which is made of high-strength steel by welding. During the manufacturing process, the specifications of the steel and the welding process are strictly controlled to ensure that the frame 1 has sufficient carrying capacity to withstand various loads generated during the assembly process of the wind turbine impeller, and at the same time ensure its structural stability to avoid deformation or damage during use. The rotating support 2 is rotatably connected to the side wall of the frame 1 through a hinge, and the rotating support 2 is also made of high-strength steel to ensure the connection strength and rotation flexibility between the rotating support 2 and the frame 1. When installing the hinge, the position and gap of the hinge are accurately adjusted to ensure that the rotating support 2 can rotate smoothly around the hinge without jamming. The platform plate 3 is firmly fixed and installed on the frame 1 and the rotating support 2, and is made of anti-slip and wear-resistant materials to provide a stable and safe working surface for the workers, preventing them from slipping or falling during operation.

[0057] The foldable support structure 4 is installed inside the frame 1, and its specific components include a driving motor 401, a driving rod 402, a driving bevel gear 403, a driven bevel gear 404, a rotating lead screw 405, a moving sliding block 406 and a support inclined rod. The driving motor 401 is fixedly installed on the side wall of the frame 1, and its output end is fixedly connected with the driving rod 402 through a shaft coupling to ensure that the driving motor 401 can stably transmit power to the driving rod 402. The other end of the driving rod 402 is fixedly connected with the driving bevel gear 403 through a key to enable the driving rod 402 to drive the driving bevel gear 403 to rotate synchronously. The driving bevel gear 403 is meshingly connected with the driven bevel gear 404, which is fixedly installed on the rotating lead screw 405. The rotating lead screw 405 is rotatably connected in the inner cavity of the frame 1 through a bearing to ensure that the rotating lead screw 405 can rotate flexibly. The moving sliding block 406 is threadedly connected to the rotating lead screw 405, and its other end is hingedly connected with one end of the support inclined rod. The other end of the support inclined rod is hingedly connected to the side wall of the rotating support 2.

[0058] When the driving motor 401 works, the driving rod 402 drives the driving bevel gear 403 to rotate. Since the driving bevel gear 403 is engaged with the driven bevel gear 404, the driven bevel gear 404 and the rotating lead screw 405 are driven to rotate. The rotation of the rotating lead screw 405 enables the moving slider 406 to move linearly thereon, and the moving slider 406 drives or pulls the rotating support 2 to rotate around the hinge through the supporting inclined rod, so as to realize the rapid folding and unfolding of the platform. During the folding and unfolding, the movements of the components are coordinated and consistent, so as to ensure that the platform can complete the actions smoothly and accurately.

[0059] The supporting adjustable structure 5 is connected to the supporting inclined rod of the foldable supporting structure 4, and mainly comprises a fixed sliding sleeve 501, a fixed shell 502, a rotating rod 503, an adjusting lead screw 508 and a moving sliding sleeve 509. The fixed sliding sleeve 501 is fixedly installed on the supporting inclined rod, and the moving sliding sleeve 509 is slidably connected in the fixed sliding sleeve 501. The bottom end of the moving sliding sleeve 509 is fixedly installed with a supporting foot, which is designed to be wide and anti-skid, so as to increase the contact area with the ground and improve the stability of the platform. The fixed shell 502 is fixedly installed on the side wall of the fixed sliding sleeve 501, and the rotating rod 503 is rotatably connected in the fixed shell 502 through a bearing. One end of the rotating rod 503 extends to the outside of the fixed shell 502 and is provided with a handle at the end, so as to facilitate manual operation of the staff; the other end is fixedly connected with the adjusting lead screw 508. The adjusting lead screw 508 is threadedly connected in the moving sliding sleeve 509. When the rotating rod 503 rotates, the adjusting lead screw 508 is driven to rotate, so as to adjust the relative position between the moving sliding sleeve 509 and the fixed sliding sleeve 501, and realize the accurate adjustment of the height of the supporting foot. During the adjustment, the adjustment of each supporting foot can be made according to the ups and downs of the local terrain, so that the platform always maintains a horizontal state.

[0060] In addition, the side wall of the frame 1 is also connected with a controller 6 and a traction ring 7. The controller 6 adopts advanced microprocessor technology and has intelligent control function, which can accurately control the working state of the driving motor 401, so as to realize the automatic folding and unfolding of the platform. The staff only needs to operate the buttons on the controller 6, so as to easily complete the operation of the platform and improve the work efficiency. The traction ring 7 is convenient for remote control and transportation of the platform by external equipment (such as a tractor). During the transportation, the traction ring 7 can bear a large pulling force, so as to ensure that the platform can be safely and stably towed. The inner cavity of the frame 1 is also connected with a storage battery 8, which provides stable power support for the electric components (such as the driving motor 401, the controller 6, etc.) on the platform. The storage battery 8 selects a high-performance and long-life product, and is equipped with a charging protection device to prevent damage to the storage battery 8 caused by overcharging or overdischarging.

[0061] Example 3 In another preferred embodiment, on the basis of the above-mentioned embodiments 1 and 2, this embodiment further provides a wind turbine impeller assembly platform for mountainous areas, which also comprises basic components such as frame 1, rotating support 2, platform plate, etc., but differs from the above-mentioned embodiments in the design of the foldable support structure and the support adjustable structure.

[0062] Frame 1 is made of aluminum alloy material, which has the advantages of light weight and corrosion resistance compared with the high-strength steel material in embodiment 2, facilitating the transportation and installation of the platform. The connection mode of rotating support 2 and frame 1 is the same as that of embodiment 2, i.e., rotating connection through hinges. Platform plate 3 is made of high-strength composite material, which not only ensures the strength and stability of platform plate 3, but also reduces the overall weight of the platform.

[0063] The foldable support structure 4 adopts a hydraulic drive mode. Inside frame 1, there are installed a hydraulic pump, a hydraulic cylinder, and a hydraulic pipeline. The hydraulic pump serves as a power source to provide pressure oil for the hydraulic system. One end of the hydraulic cylinder is hinged to frame 1, and the other end is hinged to rotating support 2. When the hydraulic pump is working, it delivers pressure oil to the hydraulic cylinder through the hydraulic pipeline, pushing the piston rod of the hydraulic cylinder to extend or retract, thereby realizing the rotation of rotating support 2 and completing the folding and unfolding of the platform. The hydraulic drive mode has the advantages of large power and smooth movement, and can better adapt to complex terrain and working environment.

[0064] The support adjustable structure 5 uses an electric push rod to realize the adjustment of the height of the support feet. An electric push rod is installed on each support inclined rod, with one end fixedly connected to the support inclined rod and the other end fixedly connected to the support foot. Through the controller 6, the extension and retraction of the electric push rod can be controlled, thereby realizing the precise adjustment of the height of the support feet. The electric push rod has the advantages of high control precision and fast response speed, and can meet the adjustment requirements of the platform under different terrain conditions.

[0065] In addition, the side wall of frame 1 is also connected with controller 6 and traction ring 7. Controller 6 adopts advanced microprocessor technology and has intelligent control function, which can accurately control the working state of the hydraulic pump and the electric push rod, realizing the automatic folding, unfolding and height adjustment of the platform. The staff only needs to operate the buttons on controller 6 to easily complete the operation of the platform, improving the work efficiency. Traction ring 7 facilitates the remote control and transportation of the platform by external equipment (such as a tractor). During transportation, traction ring 7 can withstand a large pulling force to ensure that the platform can be safely and stably towed. In the inner cavity of frame 1, there is also connected a storage battery 8, which provides stable power support for the electric components on the platform, such as controller 6, hydraulic pump (if it is an electric hydraulic pump), electric push rod, etc. Storage battery 8 is selected to be a high-performance and long-life product, and is equipped with a charging protection device to prevent damage to storage battery 8 caused by overcharging or overdischarging.

[0066] Example 4 In another preferred embodiment, based on the above-mentioned examples 1, 2, and 3, this embodiment provides a method for using the impeller assembly platform of the wind turbine generator of the mountain wind farm based on examples 1 and 2, with the specific steps as follows: 1. Transportation stage Firstly, the assembled platform is transported to the installation site of the mountain wind farm through the traction ring 7. Before transportation, check whether the folding state of the platform is correct, whether each component is fixed firmly, and ensure that the platform will not be loose or scattered during transportation. At the same time, check whether the connection of the traction ring 7 is reliable and whether the performance of the traction equipment is good. During transportation, since the platform is in a folded state, the frame 1 and its attached structures are compact and small in size, which facilitates driving on complex terrain and narrow roads. The driver should reasonably control the speed according to the road conditions to avoid sudden braking or sharp turns, and ensure that the platform can be safely and stably transported to the installation site.

[0067] 2. Expansion stage After arriving at the installation site, separate the traction vehicle from the platform and place the platform in a suitable position. Then, start the drive motor 401 through the controller 6. After the drive motor 401 starts working, the power is transmitted to the drive bevel gear 403 through the drive rod 402, the drive bevel gear 403 meshes with the driven bevel gear 404 to drive the rotating lead screw 405 to rotate. When the rotating lead screw 405 rotates, the moving block 406 moves along the rotating lead screw 405, and the moving block 406 can slide on the limiting slide rod 407, which plays a limiting and guiding role. The moving block 406 drives the connecting link 412 to move the connecting plate 409, and the connecting plate 409 drives the rotating support 2 to rotate around the hinge through the rotating support rod 410. During the rotation of the rotating support 2, the connecting plate 411 and the connecting link 413 play a supporting and driving role, the rotating pull rod 414 is connected with the connecting seat 415, and the connecting rod 416 and the moving link 417 cooperate to make the platform gradually expand to the working state. During the expansion process, the limiting sleeve 418 can slide on the rotating lead screw 405 or the limiting slide rod 407, further ensuring the coordinated movement of each component. The staff should closely observe the movement of the platform to ensure that the movement of each component is coordinated and consistent, without jamming or abnormal noise. If the platform expansion is not smooth, the drive motor 401 should be stopped immediately to check and eliminate the fault.

[0068] 3. Adjustment stage According to the field terrain conditions, manually rotate the rotating rod 503, the rotating rod 503 is provided with a knob 504 at one end, facilitating operation. The rotating rod 503 is fixed on the fixed shell 502 through the shaft fixer 505, the rotating rod 503 rotates to drive the engaging bevel gear 506 to rotate, the engaging bevel gear 506 is engaged with the connecting bevel gear 507, further driving the adjusting screw rod 508 to rotate. When the adjusting screw rod 508 rotates, the moving sleeve 509 moves along the adjusting screw rod 508, the fixed sleeve 501 is fixed on the fixed part of the supporting adjustable structure 5, and the relative position between the moving sleeve 509 and the fixed sleeve 501 changes. The moving sleeve 509 adjusts the height of each supporting leg through the supporting plate 510, so that the platform is in close contact with the ground, and the stability of the platform is ensured. During the adjustment process, the levelness of the platform can be detected by using a level, and the height of the supporting leg is fine-tuned according to the indication of the level, so that the platform reaches a horizontal state. At the same time, the contact condition of the supporting leg with the ground is checked to ensure that the supporting leg can firmly support the platform, avoiding shaking or tilting of the platform during use.

[0069] 4. Working stage After the platform is stabilized, the workers can assemble the wind turbine impeller on the platform plate 3. During the assembly process, the platform is kept in a stable state by the stable structure of the frame 1, the reasonable support of the rotating support 2, and the cooperation of the foldable supporting structure 4 and the supporting adjustable structure 5, providing a safe and stable working environment for the workers. The workers should strictly follow the assembly process requirements of the wind turbine impeller to ensure the assembly quality. At the same time, attention should be paid to operation safety to avoid dangerous actions on the platform. If fine adjustment of the platform is needed during the assembly process, the controller 6 can be used to control the reverse rotation of the drive motor 401, and the platform part structure is adjusted according to the reverse operation principle of the unfolding stage, or the height of the supporting leg is manually adjusted to achieve the fine adjustment.

[0070] 5. Folding stage After the assembly is completed, the operation is performed in the opposite order. First, the controller 6 is used to control the reverse rotation of the drive motor 401, so that the platform is gradually folded up. During the folding process, the movement of the platform should be closely observed to ensure the coordinated movement of the parts. When the platform is folded to a certain extent, the drive motor 401 is stopped, and the folding state of the platform is checked to ensure that the parts are in place. Then, the folded platform is transported to the next installation site or storage location through the traction ring 7. During the transportation or storage process, the protection of the platform should be done well to avoid collision or damage to the platform. In addition, the battery 8 provides power for the controller 6, the drive motor 401 and other parts that need power drive, ensuring the normal operation of the functions of the platform.

[0071] Example 5 In another preferred embodiment, based on the above-mentioned embodiments 1, 2 and 3, the present embodiment provides a method for using the hub assembly platform of the mountain wind farm wind turbine of embodiments 1 and 3, and the specific steps are as follows: 1. Transportation stage Similar to embodiment 4, the assembled platform is transported to the installation site by the traction ring 7. Before transportation, check whether each component of the platform is firmly connected, among which the frame 1 serves as the main support structure of the platform and its connection points need to be checked. At the same time, check whether the hydraulic system and the electric push rod are working normally. Since the platform uses hydraulic drive and electric push rod adjustment, special attention should be paid to checking the condition of the hydraulic oil and the power supply to ensure that the hydraulic oil is sufficient and the power supply (powered by the battery 8) has sufficient power.

[0072] 2. Deployment stage After arriving at the installation site, place the platform in the appropriate position and start the hydraulic pump through the controller 6. After the hydraulic pump starts working, the pressure oil is delivered to the hydraulic cylinder, the piston rod of the hydraulic cylinder is elongated, and the rotating support 2 is driven to rotate around the hinge through the connecting plate 409, so that the platform is gradually deployed. During the deployment process, observe the working condition of the hydraulic cylinder and check whether there is any leakage in the hydraulic pipeline. The hydraulic pipeline is connected to the hydraulic pump and the hydraulic cylinder. If hydraulic oil leakage is found, the hydraulic pump should be stopped immediately, the leakage position (such as the hydraulic pipeline interface, the sealing position of the hydraulic cylinder 202, etc.) should be checked and repaired.

[0073] 3. Adjustment stage According to the terrain of the site, control the extension and retraction of the electric push rod through the controller 6. One end of the electric push rod is connected to the fixed part (such as the fixed housing 502) of the adjustable support structure 5, and the other end is connected to the movable support component (such as the movable sliding sleeve 509), and the height of the support leg is adjusted by the extension and retraction of the electric push rod. During the adjustment process, a laser level can be used to detect the levelness of the platform, and each support leg is adjusted according to the detection results. In the adjustable support structure 5, the rotating rod 503 is manually rotated (if manual fine adjustment is required), the rotating rod 503 is fixed to the fixed housing 502 through the shaft fixator 505, the rotating rod 503 rotates to drive the connecting bevel gear 506 to rotate, the connecting bevel gear 506 meshes with the connecting bevel gear 507, thereby driving the adjusting lead screw 508 to rotate, the adjusting lead screw 508 rotates to make the movable sliding sleeve 509 move along the adjusting lead screw 508, the fixed sliding sleeve 501 is fixed to the fixed housing 502, and the relative position of the movable sliding sleeve 509 and the fixed sliding sleeve 501 changes, the height of the support leg is adjusted through the support plate 510 to make the platform reach the horizontal state. The laser level has the advantages of high measurement accuracy and easy operation, and can quickly and accurately detect the levelness of the platform.

[0074] 4. Working stage After the platform is stabilized, the workers perform the assembly work of the wind turbine impeller on the platform plate 3. During the assembly process, the stability of the platform is closely monitored, and the platform is kept stable by the coordinated action of the stable structure of the frame 1, the reasonable support of the rotating support 2, the foldable support structure 4, and the support adjustable structure 5. If signs of shaking or tilting of the platform are found, the height of the support feet should be adjusted in time to ensure the stability of the platform. At the same time, attention should be paid to the working state of the hydraulic system (hydraulic pump, hydraulic cylinder, etc.) and the electric push rod to avoid affecting the normal use of the platform due to overload or failure.

[0075] 5. Folding stage After the assembly is completed, the controller 6 is controlled to reverse the hydraulic pump, the piston rod of the hydraulic cylinder is retracted, the rotating support 2 is driven to rotate around the hinge through the connecting plate 409, and the platform is folded up. During the folding process, check whether the movement of each component is coordinated, including the connection and movement relationship between the frame 1, the rotating support 2, the foldable support structure 4 and other components, to ensure that the platform can be folded smoothly. After folding is completed, the platform is transported to the designated location by the traction ring 7. In addition, the battery 8 provides power for the components that need power drive, such as the controller 6, the hydraulic pump, the electric push rod, etc., to ensure the normal operation of each function of the platform.

During transportation, attention should be paid to avoid terrain obstacles to ensure smooth movement of the equipment.

[0078] Step 2: Platform unfolding operation After arriving at the designated assembly position, the worker operates the controller 6 on the frame 1, sends a start signal to the drive motor 401 in the foldable support structure 4, and controls the drive motor 401 to operate.

When the rotating screw 405 rotates, the two groups of moving sliders 406 move in opposite directions along the side wall of the rotating screw 405 under the guidance of the limiting slide rod 407.

[0085] The level of the platform plate 3 is observed by means of a level and the like, and the support adjustable structure 5 at different positions is adjusted respectively, so that the platform plate 3 meets the horizontal requirement, and the subsequent impeller assembly operation is ensured to be stably carried out.

[0086] After the platform is leveled, the shaft fixer 505 on the fixed shell 502 is operated to fix the rotating rod 503, so as to prevent the rotating rod 503 from accidentally rotating in the operation process to change the support height, and further ensure the stability of the platform.

[0087] Step 4: Impeller assembly and platform storage After the platform is fixed and stabilized, the staff carries out the assembly work of the wind turbine impeller on the platform plate 3, and the assembly process needs to follow the relevant safety specifications and technical requirements.

[0088] After the impeller assembly is completed, the operating shaft fixer 505 releases the fixation of the rotating shaft 503, reversely rotates the knob 504, and makes the moving sliding sleeve 509 drive the support plate 510 to move upward to be out of the ground support state.

[0089] By controlling the reverse rotation of the driving motor 401 through the controller 6, the driving motor 401 drives the driving rod 402, the driving bevel gear 403, the driven bevel gear 404, and the rotating lead screw 405 to reversely rotate, so that the two groups of moving sliding blocks 406 move to the middle along the rotating lead screw 405, and then drive the rotating support 2 to fold and the moving connecting rod 417 to shrink, so as to restore the platform to the folded state.
