Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind turbines, in particular to a shipping and packaging device for a wind turbine stator 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 ultimately outputs alternating current using the principle of electromagnetic induction. Currently, the stators of direct-drive wind turbines 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, the stator petals of wind turbines are shipped in two ways: horizontal placement and 45° tilt. The stator petals are shipped horizontally, that is, 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, which has high transportation costs. The stator petals are shipped at a 45° tilt. The stator petals need to be tilted 45° along the axis and connected to the side core bracket of the stator petals using a supporting fixture. In this way, the stator petals can enter the container, but the shipping fixture supporting the stator petals needs to withstand the 4g acceleration during transportation, and the support height of the shipping fixture 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 high.
[0004] Based on this, the applicant proposed a shipping packaging device for extra-wide split-petal stator petals of wind turbines to solve the above technical problems. Utility Model Content
[0005] The utility model aims at the deficiencies in the prior art and provides a shipping and packaging device for a wind turbine stator with extra-wide petal-type stators.
[0006] The utility model solves the problem through the following technical solutions:
[0007] A shipping packaging device for an extra-wide wind turbine split-type stator lobe, comprising a support base, to which at least two groups of inclined support rods are detachably connected, the inclined support rod groups comprising a high-end support seat and a low-end support seat, the upper ends of each of the high-end support seat and the low-end support seat being provided with a plurality of bolts, the two ends of the stator lobe 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 lobe is 15°~45°.
[0008] 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.
[0009] Preferably, the tube cavity of the transverse support tube and / or the longitudinal support tube forms a fork hole.
[0010] Preferably, a plurality of reinforcing ribs A are provided between the transverse support tube and the longitudinal support tube.
[0011] 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.
[0012] Preferably, a plurality of reinforcing ribs B are provided between the lower end support seat and the longitudinal support tube.
[0013] Preferably, a plurality of reinforcing ribs C are provided between the high-end support seat and the longitudinal support tube.
[0014] Preferably, a connecting rod is provided between the lower end support seats.
[0015] Preferably, anti-collision rods are provided between the ends of several of the longitudinal support tubes close to the high-end support seat.
[0016] 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 part, and the other end is bent to form a long part, the short part is parallel to the long part, and there is an inclined part between the short part and the long part.
[0017] Preferably, a top support rod is provided between corresponding bends of the two rainproof cloth support rods.
[0018] The beneficial effects of the present invention are:
[0019] 1. Improved transportation efficiency and reduced costs: This utility model utilizes a detachable tilting support rod assembly design, allowing the stator blades to be fixed to the support base at an inclined angle. This not only ensures that the stator blades can be smoothly transported in standard containers, reducing the high transportation costs associated with using flat rack containers, but also reduces the volume and weight of the overall packaging device through optimized structure, further saving transportation costs.
[0020] 2. Enhanced load-bearing capacity and stability: By installing multiple sets of inclined support rods on the support base and fastening the ends of the stator disc to the high and low end support bases with bolts, the stator disc is firmly fixed during transportation. At the same time, the installation of various reinforcing ribs and connecting rods significantly improves the load-bearing capacity and impact resistance of the support base and the entire shipping packaging device, ensuring that the stator disc will not deform or be damaged during long-distance transportation. The use of anti-collision bars prevents the stator disc from being bumped during forklift transportation and serves as a guide when the stator disc is forklifted into the container.
[0021] 3. Simplified design and reduced manufacturing costs: Compared to traditional, complex support fixture designs, the present invention features a simpler, clearer structure, making it easier to manufacture and install. The detachable design of the tilting support rod assembly not only facilitates assembly before and disassembly after transportation, but also facilitates adjustment to accommodate stator lobes of varying sizes, improving versatility and flexibility, thereby reducing overall manufacturing costs.
[0022] 4. Improved safety and reliability: Through a rational structural design and a stable fixing method, this utility model effectively reduces the risk of damage to the stator lobes during transportation due to external factors such as vibration and impact, thereby improving transportation safety and reliability. Furthermore, the design of the tarpaulin support rods and top support rods also takes into account the need for rain and dust protection, further protecting the stator lobes from environmental factors. Replacing the wooden frame with tarpaulin for protection reduces manufacturing costs.
[0023] 5. Adaptability and flexibility: The shipping packaging device of this utility model can flexibly adapt to split-type 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 groups, thereby enhancing the adaptability and flexibility of the device.

[0035] 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 embodiments described are only some of the embodiments of the present invention, not all of them. 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. Example 1:
[0036] like Figures 1 to 9As shown, the utility model is a shipping packaging device for a wind turbine stator petal with an extra-wide size, comprising 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. The upper ends of the high-end support seat 5 and the low-end support seat 6 are each provided with a plurality of bolts, and the two ends of the stator petal are detachably connected to the high-end support seat 5 and the low-end support seat 6 by the bolts, so as to be tilted and fixed on the support base 1. The inclination angle range of the stator petal is 15°~45°. When the inclination angle is greater than 15°, the external dimensions of the stator petal can enter the container; when the inclination angle is less than 45°, the single-sided load-bearing at the stator petal connection meets the material strength requirements.
[0037] 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 smoothly enter the standard container for transportation, reducing the high transportation costs brought about 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.
[0038] Compared with the traditional complex support tooling design, the structure of the utility model is simpler and clearer, and is easy 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 overall manufacturing costs.
[0039] 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. The tube cavities of the transverse support tubes 11 and / or the longitudinal support tubes 12 form fork transportation holes 13 to facilitate forklift transportation.
[0040] Several reinforcing ribs A7 are arranged between the transverse support tube 11 and the longitudinal support tube 12, several reinforcing ribs B8 are arranged between the low-end support seat 6 and the longitudinal support tube 12, several reinforcing ribs C9 are arranged between the high-end support seat 5 and the longitudinal support tube 12, and a connecting rod 4 is arranged between the low-end support seats 6 to strengthen the overall support strength and resist the load during transportation.
[0041] The provision of the reinforcing ribs and the connecting rods 4 significantly improves the load-bearing capacity and impact resistance of the support base 1 and the entire shipping packaging device, ensuring that the stator flaps are not deformed or damaged during long-distance transportation.
[0042] 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.
[0043] Anti-collision bars 10 are provided between the ends of several longitudinal support tubes 12 close to the high-end support seat 5. The anti-collision bars 10 are used to prevent the stator lobe from being bumped during forklift transportation and to guide the stator lobe when it is forklift transported into the container.
[0044] 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 part 21, and the other end is bent to form a long part 22, the short part 21 is parallel to the long part 22, and there is an inclined part 23 between the short part 21 and the long part 22. 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. The inclined rainproof cloth facilitates the drainage of rainwater from the top.
[0045] 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 blades from environmental factors, and reducing manufacturing costs by replacing wooden frames with rainproof cloth.
[0046] In other embodiments, the low-end support seat 6 and the high-end support seat 5 can also be fixedly connected to the upper side of the longitudinal support tube 12 by welding.
[0047] In other embodiments, the anti-collision rod 10 can also be replaced with an anti-collision plate or an anti-collision column according to actual needs.
[0048] In other embodiments, if the carrying load is small, the stator flap can also be fixed to the inclined support rod group by other means, such as snap-fitting rope fixing, etc. Those skilled in the art can make adaptive adjustments to the inclined support rod group according to actual needs to meet different transportation needs.
[0049] In other embodiments, the tops of the two ends of the rainproof cloth support rod 2, which are bent with equal lengths, are flush after being fixed on the support base 1 .
[0050] In other embodiments, the low-end support seat 6 and the high-end support seat 5 can also be 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.
