Description

Technical Field

[0001] The invention relates to the technical field of wind turbine generators, and in particular to a shipping packaging device for a wind turbine generator split-petal stator flap with an ultra-wide size. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate, and uses the principle of electromagnetic induction to ultimately output alternating current. Currently, direct-drive wind turbine stators adopt two structures: integral and split. For easy transportation, high-power models mostly adopt a split stator structure, which divides the entire circular stator into 12 equal parts of stator petals. The stator petals are transported to the customer's site via shipping tooling and then assembled. Therefore, the carrying capacity of the shipping tooling must be considered during the transportation of the stator petals to ensure that the stator petals and the shipping tooling are not deformed. At the same time, the shipping and manufacturing costs of the stator petals must also be considered.

[0003] At present, there are two shipping methods for the split-petal stator petals of wind turbines: horizontal placement and 45° tilted placement. The stator petals are shipped horizontally, and the stator petals are placed horizontally on a wooden base. The overall shipping width is too wide, and the stator petals cannot enter the container. They can only be transported in a frame box, and the transportation cost is relatively high. The stator petals are shipped at a 45° tilt, and the stator petals need to be tilted 45° along the axial direction, and the side core brackets of the stator petals are connected using supporting fixtures. In this way, the stator petals can enter the container, but the shipping fixture supporting the stator petals needs to resist the 4g acceleration during transportation, and the shipping fixture support height is relatively high, which is not conducive to transportation. At the same time, the design structure of the shipping fixture is complex and the manufacturing cost is relatively high.

[0004] Based on this, the applicant proposed a shipping packaging device for wind turbine split-petal stator petals with extra-wide dimensions to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a shipping packaging device for a wind turbine split-petal stator flap with an ultra-wide size.

[0006] The present invention is solved by the following technical solutions: A shipping packaging device for a wind turbine split-type stator petal with extra-wide dimensions, comprising a support base, to which at least two groups of inclined support rod groups are detachably connected, the inclined support rod groups comprising a high-end support seat and a low-end support seat, a plurality of bolts being provided at the upper ends of the high-end support seat and the low-end support seat, the two ends of the stator petal being detachably connected to the high-end support seat and the low-end support seat respectively by the bolts, thereby being tilted and fixed on the support base, and the inclination angle range of the stator petal is 15°~45°.

[0007] Preferably, the support base includes two transverse support tubes, two longitudinal support tubes are vertically arranged on the transverse support tubes, and the transverse support tubes are fixedly connected to the longitudinal support tubes to form the support base in a "well" shape.

[0008] Preferably, the tube cavity of the transverse support tube and / or the longitudinal support tube forms a fork transport hole.

[0009] Preferably, a plurality of reinforcing ribs A are provided between the transverse support tube and the longitudinal support tube.

[0010] Preferably, the low-end support seat and the high-end support seat are both fixedly connected to the upper side of the longitudinal support tube by bolts.

[0011] Preferably, a plurality of reinforcing ribs B are provided between the lower end support seat and the longitudinal support tube.

[0012] Preferably, a plurality of reinforcing ribs C are provided between the high-end support seat and the longitudinal support tube.

[0013] Preferably, a connecting rod is provided between the lower end support seats.

[0014] Preferably, anti-collision rods are arranged between the ends of the plurality of longitudinal support tubes close to the high-end support seat.

[0015] Preferably, a rainproof cloth support rod is symmetrically arranged on the support base, one end of the rainproof cloth support rod is bent to form a short portion, and the other end is bent to form a long portion, the short portion is parallel to the long portion, and an inclined portion is between the short portion and the long portion.

[0016] Preferably, a top support rod is provided between corresponding bends of the two rainproof cloth support rods.

[0017] The beneficial effects of the present invention are: 1. Improve transportation efficiency and reduce costs: The detachable tilting support rod group design adopted in the present invention enables the stator flap to be fixed on the support base at an inclined angle, which not only ensures that the stator flap can be smoothly transported into a standard container, reducing the high transportation costs caused by the use of a frame box, but also reduces the volume and weight of the overall packaging device by optimizing the structure, further saving transportation costs; 2. Enhanced bearing capacity and stability: By setting multiple groups of inclined support rods on the support base and fastening the two ends of the stator disc to the high and low end support seats with bolts, the stator disc is firmly fixed during transportation. At the same time, the setting of various reinforcing ribs and connecting rods significantly improves the bearing capacity and impact resistance of the support base and the entire shipping packaging device, ensuring that the stator disc is not deformed or damaged during long-distance transportation. The application of anti-collision rods prevents the stator disc from being bumped during forklift transportation and plays a guiding role when the stator disc is forklifted into the container; 3. Simplified design and reduced manufacturing cost: Compared with the traditional complex support tooling design, the structure of the present invention is simpler and clearer, and is easy to manufacture and install. The detachable design of the tilting support rod group is not only convenient for assembly before transportation and disassembly after transportation, but also convenient for adjustment according to stator petals of different sizes, which improves versatility and flexibility, thereby reducing the overall manufacturing cost; 4. Improved safety and reliability: Through reasonable structural design and stable fixing method, the present invention effectively reduces the risk of damage to the stator flaps due to external factors such as vibration and impact during transportation, and improves the safety and reliability of transportation. At the same time, the design of the rainproof cloth support rod and the top support rod also takes into account the needs of rain and dust prevention, further protecting the stator flaps from environmental factors. The rainproof cloth replaces the wooden frame for protection, reducing the manufacturing cost; 5. Adaptability and flexibility: The shipping packaging device of the present invention can flexibly adapt to the stator petals of different sizes and weights. Whether it is a small or high-power wind turbine stator petal, it can be firmly fixed and transported by adjusting the number and position of the inclined support rod group, thereby enhancing the adaptability and flexibility of the device.

[0029] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0030] like Figures 1 to 9 As shown, a shipping packaging device for a wind turbine split-petal stator flap with extra-wide dimensions of the present invention comprises a support base 1, to which two groups of inclined support rod groups are detachably connected, and the inclined support rod groups include a high-end support seat 5 and a low-end support seat 6. A plurality of bolts are provided on the upper ends of the high-end support seat 5 and the low-end support seat 6, and the two ends of the stator flap are detachably connected to the high-end support seat 5 and the low-end support seat 6 respectively by the bolts, so as to be tilted and fixed on the support base 1, and the inclination angle range of the stator flap is 15°~45°. When the inclination angle is greater than 15°, the outer dimensions of the stator flap can enter the container; when the inclination angle is less than 45°, the single-sided load-bearing at the stator flap connection meets the material strength requirements.

[0031] The detachable inclined support rod group design adopted in the present invention enables the stator flap to be fixed on the support base 1 at an inclined angle, which not only ensures that the stator flap can be smoothly transported into the standard container, reducing the high transportation costs caused by the use of frame boxes, but also reduces the volume and weight of the overall packaging device by optimizing the structure, further saving transportation costs; by arranging multiple groups of inclined support rod groups on the support base 1, and using bolts to fasten the two ends of the stator flap to the high and low end support seats, the stator flap is firmly fixed during transportation.

[0032] Compared with the traditional complex support tooling design, the structure of the present invention is simpler and clearer, easier to manufacture and install. The detachable design of the inclined support rod group is not only convenient for assembly before transportation and disassembly after transportation, but also convenient for adjustment according to stator petals of different sizes, thereby improving versatility and flexibility, thereby reducing the overall manufacturing cost.

[0033] The support base 1 includes two transverse support tubes 11, and two longitudinal support tubes 12 are vertically arranged on the transverse support tubes 11. The transverse support tubes 11 and the longitudinal support tubes 12 are fixedly connected to form the support base 1 in a "well" shape.

[0036] The low-end support seat 6 and the high-end support seat 5 are both fixedly connected to the upper side of the longitudinal support tube 12 by bolts, so as to facilitate disassembly and recycling after transportation.

[0037] An anti-collision rod 10 is arranged between the ends of the plurality of longitudinal support tubes 12 close to the high-end support seat 5. The anti-collision rod 10 is used to prevent the stator disc from being bumped during forklift transportation and to guide the stator disc when it is forklift transported into the container.

[0038] The support base 1 is also symmetrically provided with rainproof cloth support rods 2, one end of the rainproof cloth support rod 2 is bent to form a short portion 21, and the other end is bent to form a long portion 22, the short portion 21 is parallel to the long portion 22, and an inclined portion 23 is between the short portion 21 and the long portion 22, and a top support rod 3 is provided between the corresponding bending parts of the two rainproof cloth support rods 2, which is used to support the rainproof cloth during transportation, and the inclined rainproof cloth can facilitate the removal of rainwater on the top.

[0039] The design of the rainproof cloth support rod 2 and the top support rod 3 also takes into account the needs of rain and dust protection, further protecting the stator flap from environmental factors, and reducing manufacturing costs by replacing wooden frame protection with rainproof cloth.

[0040] In other embodiments, the low-end support seat 6 and the high-end support seat 5 may also be fixedly connected to the upper side of the longitudinal support tube 12 by welding.

[0041] In other embodiments, the anti-collision rod 10 may also be replaced with an anti-collision plate or an anti-collision column according to actual needs.

[0042] In other embodiments, if the carrying load is small, the stator vanes can also be fixed to the inclined support rod group by other means, such as snap-fitting rope fixing methods, etc. Technical personnel in this field can make adaptive adjustments to the inclined support rod group according to actual needs to meet different transportation needs.

[0043] In other embodiments, the tops of the parts with equal lengths bent at both ends of the rainproof cloth support rod 2 are flush after being fixed on the support base 1 .

[0044] In other embodiments, the low-end support seat 6 and the high-end support seat 5 may also be both fixedly connected to the upper side of the transverse support tube 11, or the low-end support seat 6 is fixedly connected to the upper side of the transverse support tube 11, and the high-end support seat 5 is fixedly connected to the upper side of the longitudinal support tube 12, or the high-end support seat 5 is fixedly connected to the upper side of the transverse support tube 11, and the low-end support seat 6 is fixedly connected to the upper side of the longitudinal support tube 12, that is, the connection between the low-end support seat 6 and the high-end support seat 5 and the stator lobe can be a same-side connection or a different-side connection.
