[0002] Wind power generation is the conversion of wind kinetic energy into electrical energy. As a clean and renewable energy source, wind energy is increasingly valued by countries around the world. Wind power generation equipment is mostly installed in remote areas. Wind power in remote areas can meet the power generation requirements, but the terrain in remote areas is complex, uneven, and even without roads, making the installation of wind power generation equipment difficult and the construction progress slow. At present, the installation locations of most wind turbine impellers are surrounded by forests. For the sake of protecting the ecology, trees cannot be cut down, so the ground installation space is small, resulting in inconvenient installation, low efficiency, and low safety.

The climbing ladder is convenient for operators to climb, and the guardrail greatly improves the safety of operators on the top of the platform; when the wind turbine impeller is installed, it can be hoisted onto the wind turbine impeller assembly and hoisting platform for mountain wind farms, which has good stability and high work efficiency; the utility model overcomes the problem of uneven ground, and the installation is safer, and the height of the hoisting platform is greater than the height of the trees at the installation site, so it can be installed above the tree space, ensuring a larger installation space without affecting the trees;

[0004] Although the above equipment can assemble the impeller of the wind turbine and then hoist it, in actual operation, the metal frame is easily affected by uneven ground support force under complex terrain and environmental conditions in the field, resulting in local deformation of the frame and affecting the overall stability.

[0022] See also Figure 1-8The utility model provides a wind turbine impeller assembly and hoisting platform for a mountain wind farm, comprising a second assembly platform 2, a first assembly platform 1 being installed on one side of the second assembly platform 2, the second assembly platform 2 comprising a bearing platform 22, and a base 24 being fixedly installed at the bottom of the bearing platform 22, and a supporting steel 25 being fixedly arranged inside the base 24, and a first row of chisels 26 being fixedly arranged on the left side of the bottom of the supporting steel 25, a third row of chisels 28 being fixedly arranged on the right side of the bottom of the supporting steel 25, and a second row of chisels 27 being fixedly arranged in the middle of the bottom of the supporting steel 25, and a protective sheet 30 covering the bottom of the base 24, three groups of equidistantly distributed protective frames 31 being evenly installed on the protective sheet 30, and the three groups of protective frames 31 being respectively wrapped around the outer sides of the first row of chisels 26, the second row of chisels 27 and the third row of chisels 28, and the first row of chisels 26, the second row of chisels 27 and the third row of chisels 28 are all composed of a plurality of groups of equidistantly arranged cylindrical insert chisels.

[0023] Working principle: After the first assembly platform 1 and the second assembly platform 2 are assembled through two sets of assembly strips 33 and assembly grooves 34, a support platform is formed. The wind turbine set can be placed on this platform by hoisting. After the wind turbine set has completed the installation of the blades on this platform, the installation work can be carried out by hoisting equipment.

[0024] The first assembly cap 1 and the second assembly cap 2 are both provided with a first row of chisels 26, a second row of chisels 27 and a third row of chisels 28 at the bottom. The sharp bottoms of the first row of chisels 26, the second row of chisels 27 and the third row of chisels 28 are inserted into the interior of the leveling and compacting soil platform to standardize the surface level of the first assembly cap 1 and the second assembly cap 2;

[0025] The sharp bottoms of the first row of dowels 26, the second row of dowels 27, and the third row of dowels 28 are inserted into the leveling and compacted soil platform. A total of six rows of dowels penetrate deep into the compacted soil, which can provide additional anchoring force and effectively prevent the platform surface from slipping or tilting during assembly and lifting. When encountering strong winds or other external forces, the platform can remain stable to ensure construction safety. The soil wrapping and supporting the dowels helps to disperse the impeller weight and lifting load borne by the platform, thereby improving the overall carrying capacity of the platform; it can withstand greater impact and vibration to ensure stability during impeller assembly and lifting operations.

[0026] As a preferred embodiment, two groups of assembly grooves 34 are respectively opened on the right side surface of the second assembly base 2, and two groups of assembly strips 33 are respectively fixedly connected to the left side surface of the first assembly base 1. At the same time, the second assembly base 2 and the first assembly base 1 are positioned and assembled through the assembly strips 33 and the assembly grooves 34.

[0027] The cross-sections of the assembling strip 33 and the assembling groove 34 are both isosceles trapezoidal structures, and the length of the assembling strip 33 is equal to the depth of the assembling groove 34 .

[0028] The second assembly platform 2 and the first assembly platform 1 are positioned and assembled by means of the assembly strips 33 and the assembly grooves 34. The setting of the assembly strips 33 and the assembly grooves 34 can quickly connect the second assembly platform 2 and the first assembly platform 1, while ensuring the stability of the connection between the second assembly platform 2 and the first assembly platform 1, and reducing the gap between the second assembly platform 2 and the first assembly platform 1.

[0029] As a preferred embodiment, three groups of arc-shaped positioning openings 23 are evenly opened on the surface of the load-bearing platform 22, and the surface of the load-bearing platform 22 is covered with a rubber buffer pad 20. At the same time, three groups of equidistantly arranged arc-shaped positioning pieces 21 are evenly fixed on the bottom of the rubber buffer pad 20, and the positioning pieces 21 are adapted to the size of the positioning openings 23, and the positioning pieces 21 are inserted into the inside of the positioning openings 23.

[0030] The surface areas of the rubber buffer pad 20 and the load-bearing platform 22 are consistent, and both the rubber buffer pad 20 and the load-bearing platform 22 are semicircular structures. The cross-section of the base 24 at the bottom of the load-bearing platform 22 is a "U"-shaped setting, and multiple groups of equidistantly arranged support steels 25 are evenly fixed inside the base 24. At the same time, the cross-section of the support steel 25 is an I-shaped setting.

[0031] Semicircular rubber cushions 20 are provided on the surfaces of the first assembly platform 1 and the second assembly platform 2. The two groups of rubber cushions 20 are combined together to form a circular cushion sheet. The bottom of the wind turbine is covered on the circular cushion sheet, which has the following advantages:

[0032] 1. The rubber pad has a large friction coefficient, which can effectively prevent the impeller from sliding during assembly and lifting, and improve the safety and stability of operation;

[0033] 2. During the hoisting process, the rubber pad can absorb some of the impact and vibration, reducing damage to the platform structure and impeller; when the wind turbine falls, the rubber pad can play a buffering role and protect the wind turbine from strong impact;

[0034] 3. Avoid direct contact between the wind turbine and the metal surface of the platform to reduce wear and scratches and extend the service life of the platform; prevent the sharp parts of the wind turbine from leaving scratches or dents on the platform;

[0035] 4. The rubber pad can absorb some of the noise generated during operation and improve the working environment; especially when the wind turbine is running and the components are moving, it can significantly reduce the noise level;

[0036] 5. Rubber has insulating properties, which can reduce the risk of static electricity generation and conductivity, ensuring the safety of construction workers and the normal operation of equipment.

[0037] Limiting grooves 29 are provided on both sides of the bottom of the base 24 , and limiting strips 32 are fixedly provided on both sides of the surface of the protective sheet 30 , and the limiting strips 32 are inserted into the limiting grooves 29 .
