Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation tooling technology, and in particular to a blade transportation support with early warning function. Background Technology

[0002] A wind turbine generator set mainly consists of three parts: tower, nacelle, and rotor. The rotor is mainly responsible for converting wind energy into mechanical energy. The rotor mainly includes blades and hub. The blades are connected to the hub through their blade roots. The blades are one of the core components of the wind turbine generator set. If the materials of the blades gradually age or are damaged by extreme weather, the damaged wind turbine blades need to be replaced in time.

[0003] Due to the large size, weight, and length of the blades, their transportation is extremely troublesome. Currently, special transport vehicles and supports are used during transportation. The supports stably support the blades in the transport vehicle. However, due to the complex and changeable roads during transportation, the blades are prone to bumping or tilting, which can lead to damage. At present, the transportation process mainly relies on the experience and observation of the transport personnel to judge the stability of the wind turbine blades. However, the above methods are prone to misjudgment or untimely judgment, which seriously affects the safety of blade transportation. Utility Model Content

[0004] The main purpose of this invention is to propose a blade transport support with an early warning function, which aims to solve the technical problem of poor safety during blade transport.

[0005] To achieve the above objectives, this utility model proposes a blade transport support with an early warning function, the transport support comprising: A base that extends laterally; The support mechanism includes two brackets arranged laterally at a distance from the top of the base, the tops of the two brackets being used to support the blade roots; The fixing mechanism includes two fixing plates, both of which are disposed on the top of the base. The two fixing plates are respectively located on one side of the two brackets along the longitudinal direction. Each fixing plate has a through hole, and the end face of the leaf root supported on the top surface of the multiple brackets is fastened to the through hole by fastening bolts. The warning module includes a prompter, a processor, and two pressure sensors. The prompter and the processor are mounted on the base. Each of the brackets is positioned between itself and the base, and the prompter and the two pressure sensors are electrically connected to the processor.

[0006] In one embodiment, the support mechanism further includes a connecting plate, which is fastened to the base by fasteners, and both brackets are connected to the top of the connecting plate; both pressure sensors are disposed between the connecting plate and the base.

[0007] In one embodiment, each of the brackets includes a tray and a support frame. The bottom of the support frame is connected to the connecting plate, and the tray is connected to the top of the support frame. The support frame, the connecting plate, and the tray together form a cavity, and each tray is an arc-shaped tray that matches the outer contour of the leaf root.

[0008] In one embodiment, each of the trays is provided with a cushioning pad on its top, and the cushioning pad completely covers the top of the corresponding tray.

[0009] In one embodiment, the base is provided with two limiting plates, which are spaced apart laterally and extend longitudinally. Two brackets are disposed between the two limiting plates, and each bracket abuts against the limiting plate adjacent to it.

[0010] In one embodiment, each of the limiting plates is provided with a reinforcing rib on the side opposite to the bracket, and the bottom of the reinforcing rib is connected to the base.

[0011] In one embodiment, the base includes a bottom plate, a top plate, and a plurality of reinforcing plates. The bottom plate and the top plate extend laterally, and each of the reinforcing plates is arranged vertically. The top and bottom of each of the reinforcing plates are respectively connected to the top plate and the bottom plate, and the plurality of reinforcing plates are spaced apart laterally. The two brackets and the two fixing plates are both disposed on the top of the top plate. Along the horizontal direction, the two outermost reinforcing plates are the first reinforcing plates, and the indicator is disposed on either of the first reinforcing plates.

[0012] In one embodiment, the warning module further includes two distance sensors, both of which are located at the bottom of the top plate and are respectively disposed at both ends of the top plate along the horizontal direction. Both distance sensors are electrically connected to the processor, and avoidance holes are provided on the bottom plate at the positions corresponding to the sensing ends of each distance sensor.

[0013] In one embodiment, each of the through holes is a strip-shaped through hole, and the strip-shaped through hole extends vertically.

[0014] In one embodiment, the indicator is a buzzer or a warning light.

[0015] This invention relates to a blade transport support with an early warning function. Wind turbine blades are stably supported on a transport vehicle using this support. Two brackets are installed at the top of the base, providing two-point support for the blade root, resulting in good stability. A fixing mechanism, including two fixing plates, further enhances the stability of the blade during transport by fastening bolts to the fixing plates. Pressure sensors are installed between each bracket and the base to detect the pressure from the blade root on the brackets and send the detected pressure signals to a processor. When the transport vehicle travels on bumpy roads, makes sharp turns, or tilts, a shift in the blade's center of gravity can cause changes in the pressure values ​​sensed by the pressure sensors on both sides. The processor can be configured to trigger an alert when the pressure value detected by at least one pressure sensor exceeds a preset safety threshold. This allows transport personnel to immediately recognize that the blade is unstable and take timely measures such as slowing down or stopping for inspection, effectively preventing blade imbalance and significantly improving the safety of blade transport.

[0023] This utility model proposes a blade transport support 100 with an early warning function.

[0024] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the transport bracket 100 includes a base 1, a support mechanism 2, a fixing mechanism 3, and an early warning module 4. The base 1 extends laterally. The support mechanism 2 includes two brackets 21 spaced laterally on the top of the base 1, the tops of which are used to support the blade roots. The fixing mechanism 3 includes two fixing plates 31, both of which are located on the top of the base 1. The two fixing plates 31 are respectively located on one side of the two brackets 21 along the longitudinal direction. Each fixing plate 31 has a through hole 311, and the end face of the blade root supported on the top surface of the multiple brackets 21 is fastened to the through hole 311 by fastening bolts. The early warning module 4 includes an indicator 41, a processor 44, and two pressure sensors 42. The indicator 41 and the processor 44 are disposed on the base 1. Pressure sensors 42 are disposed between each bracket 21 and the base 1, and the indicator 41 and the two pressure sensors 42 are electrically connected to the processor.

[0025] This utility model discloses a blade transport support 100 with an early warning function, in which the blades of a wind turbine generator can be stably supported on a transport vehicle. By setting two brackets 21 on the top of the base 1, the two brackets 21 provide two-point support for the blade root, resulting in good support stability. Furthermore, by setting a fixing mechanism 3, which includes two fixing plates 31, the blade root is also fastened to the fixing plates 31 by fastening bolts, further improving the stability of the blade during transportation. In addition, by setting a pressure sensor 42 between each bracket 21 and the base 1, the pressure from the blade root borne by the two brackets 21 can be sensed, and the sensed pressure signal is sent to the processor 44 for processing. When the transport vehicle travels on bumpy roads, makes sharp turns, or tilts, if the center of gravity of the blade shifts, the pressure values ​​sensed by the pressure sensors 42 on both sides will change. The processor 4 can be configured to trigger the prompter 41 to issue a warning when the pressure value sensed by at least one pressure sensor 42 exceeds a preset safety threshold range. This allows transport personnel to be aware that the blade is in an unstable state as soon as possible, and thus take timely measures such as slowing down and stopping for inspection, effectively avoiding blade imbalance and greatly improving the safety of the blade transport process.

[0026] It should be noted that in this embodiment, the pressure sensor, processor, and indicator, as well as the interaction process between them, all employ existing technologies. The indicator can be a warning light or a buzzer. In other embodiments, the indicator 41 can also be a light alarm or an audible and visual alarm, which can alert the user visually and / or audibly. Furthermore, the pressure sensor 42, processor 44, and indicator 41 can all be powered by the power supply of the transport vehicle itself, or by a power supply provided on the base 1.

[0027] like Figure 1 As shown, it should be noted that in this embodiment, the horizontal, vertical, and longitudinal directions are respectively left-right, front-back, and up-down directions. The front direction is also the direction the vehicle travels during transport. The indicator is mainly located on the left or right side of the base, as the left and right sides are more likely to alert transport personnel.

[0028] In one embodiment, the support mechanism 2 further includes a connecting plate 22, which is fastened to or released from the base 1 by fasteners 221, and two brackets 21 are connected to the top of the connecting plate 22; two pressure sensors 42 are disposed between the connecting plate 22 and the base 1.

[0029] Understandably, by connecting the two brackets 21 to the top of the connecting plate 22, and by fastening the connecting plate 22 to or loosening it from the base 1 using fasteners 221, the connecting plate 22 and the two brackets 21 can be disassembled from the base 1. This facilitates replacement if either the connecting plate 22 or at least one of the two brackets 21 is damaged, saving maintenance costs. Furthermore, the two pressure sensors 42 are disposed between the connecting plate 22 and the base 1. If the pressure sensor 42 malfunctions, it can be repaired or replaced by disassembling the connecting plate 22 and the two brackets 21.

[0030] It should be noted that fastener 221 can be a bolt from the prior art.

[0031] In one embodiment, each bracket 21 includes a support plate 211 and a support frame 212. The bottom of the support frame 212 is connected to the connecting plate 22, and the support plate 211 is connected to the top of the support frame 212. The support frame 212, the connecting plate 22, and the support plate 211 together form a cavity, and each support plate 211 is an arc-shaped support plate 211 that matches the outer contour of the leaf root.

[0032] The bracket 211, support frame 212, and connecting plate 22 together form a cavity, which not only reduces the amount of material used, but more importantly, reduces the overall weight of the transport bracket 100, making it easier to handle. Specifically, weight-reducing holes are also provided on the support frame 212 to further reduce the weight.

[0033] In addition, each pallet 211 is an arc-shaped pallet 211 that matches the outer contour of the blade root, which effectively increases the contact area between the pallet 211 and the blade root, and further improves the stability of the blade root during transportation.

[0034] In one embodiment, each support plate 211 is provided with a cushioning pad 213 on its top, and the cushioning pad 213 completely covers the top of the corresponding support plate 211. Understandably, by providing the cushioning pad 213, direct rigid contact between the support plate 211 and the blade root is avoided, thereby effectively preventing damage such as blade root scratches and effectively protecting the overall wind turbine blade. Specifically, the cushioning pad 213 can be made of rubber, polyurethane, or other polymer elastic materials.

[0035] In one embodiment, the base 1 is provided with two limiting plates 14, which are arranged laterally and extend longitudinally. Two brackets 21 are arranged between the two limiting plates 14, and each bracket 21 abuts against the limiting plate 14 adjacent to it.

[0036] Understandably, by setting two limiting plates 14 on the base 1 and placing two brackets 21 between the two limiting plates 14, when the blade root is supported on the bracket 21, since the top of the bracket 21 is arc-shaped, the bracket 21 is also subjected to forces in the left and right directions. That is, the left bracket 21 is subjected to a force from the blade root toward the left, and the left limiting plate 14 can support the left bracket 21 and offset part of the force in the left direction; the right bracket 21 is subjected to a force from the blade root toward the right, and the right limiting plate 14 can support the right bracket 21 and offset part of the force in the right direction, further enhancing the stability of the bracket 21 and effectively preventing the bracket 21 from deforming and being damaged.

[0037] Furthermore, in order to improve the stability between the bracket 21 and the base 1, each connecting plate 22 and the adjacent bracket 21 are also fastened with bolts.

[0038] In one embodiment, each limiting plate 14 is further provided with a reinforcing rib 15 on the side opposite to the bracket 21, and the bottom of the reinforcing rib 15 is connected to the base 1. Understandably, by providing the reinforcing rib 15 and fixing it to the limiting plate 14, the stability of the limiting plate 14 is further improved, preventing the limiting plate 14 from bending and being damaged relative to the base 1, thus improving reliability.

[0039] Specifically, the number of reinforcing ribs 15 connected to any of the limiting plates 14 can be set to two, three, etc., and the specific number is not limited.

[0040] Please combine Figure 2 and Figure 3In one embodiment, the base 1 includes a bottom plate 12, a top plate 11, and a plurality of reinforcing plates 13. The bottom plate 12 and the top plate 11 extend laterally, and each reinforcing plate 13 is arranged vertically. The top and bottom of each reinforcing plate 13 are respectively connected to the top plate 11 and the bottom plate 12, and the plurality of reinforcing plates 13 are spaced apart laterally. Two brackets 21 and two fixing plates 31 are both arranged on the top of the top plate 11. Laterally, the two outermost reinforcing plates 13 are first reinforcing plates 131, and the indicator 41 is arranged on any of the first reinforcing plates 131.

[0041] Understandably, the base 1 consists of a base plate 12, a top plate 11, and reinforcing plates, facilitating individual fabrication and assembly. The base plate 12 is parallel to the bottom surface, and its bottom surface is flat, ensuring greater stability. Supported by multiple reinforcing plates, the structure is robust, saving materials and reducing the overall weight of the base 1, making it easy to transport. Furthermore, placing the indicator 41 on any of the outermost first reinforcing plates 131 makes the alerts emitted by the indicator 41 more easily received by transport personnel, improving reliability.

[0042] Please see Figure 3 and Figure 4 In one embodiment, the warning module 4 further includes two distance sensors 43. Both distance sensors 43 are disposed at the bottom of the top plate 11 and are respectively disposed at both ends of the top plate along the horizontal direction. Both distance sensors 43 are electrically connected to the indicator 41. A clearance hole 121 is provided on the bottom plate 12 at the position corresponding to the sensing end of each distance sensor 43.

[0043] Understandably, since the transport bracket 100 is fixed to the transport vehicle during transport, it is necessary to ensure that the transport bracket 100 does not shake relative to the transport vehicle during the transport process. In actual use, the base plate 12 of the base 1 is supported on the transport vehicle and the base 1 is fastened to the transport vehicle by bolts or ropes. By setting a distance sensor 43 on the top plate 11, the sensing end of the distance sensor 43 can sense the distance between it and the transport vehicle. If the transport bracket 100 shakes due to the base 1 being unstable or loose during transport, the distance sensor 43 will sense a change in the distance between it and the transport vehicle. If the distance change exceeds a certain value range, the processor 44 will trigger the prompt 41 to remind the user that the transport bracket 100 is not securely fixed or is loose, thereby avoiding situations such as blade tipping due to the instability of the transport bracket 100 and further improving the safety of blade transport.

[0044] It should be noted that the distance sensor 43 can be a laser distance sensor 43 or other existing technologies.

[0045] Furthermore, the base 1 also includes a support plate 16, which extends laterally and is connected to the top plate 11 and the bottom plate 12 at its top and bottom, respectively. In addition, the other reinforcing plates 13 besides the first reinforcing plate 131 are second reinforcing plates 132, and each second reinforcing plate 132 has a perforation.

[0046] Specifically, the processor 44 is disposed on the front side of the support plate 16. The first wiring harness 421 of each pressure sensor 42 is disposed on the bottom of the top plate 11 and passes through the hole on the support plate 16 and is electrically connected to the processor 44. The second wiring harness 431 of each distance sensor 43 is disposed on the front side of the support plate 16 and passes through the through hole in the second reinforcing plate 132 and is electrically connected to the processor 44. This arrangement can avoid the first wiring harness 421 and the second wiring harness 431 from being exposed. By placing the first wiring harness 421 and the second wiring harness 431 between the top plate 11 and the bottom plate 12, the first wiring harness 421 and the second wiring harness 431 can be effectively protected.

[0047] In one embodiment, each through hole 311 is a strip-shaped through hole 311, and the strip-shaped through hole 311 extends vertically. Understandably, depending on the size of the blade root, the blade root can be fixed with fastening bolts through different positions of each strip-shaped through hole 311, resulting in better versatility. Furthermore, to better fix the blade root, each fixing plate 31 may have multiple strip-shaped through holes 311, and these multiple strip-shaped through holes 311 are distributed at lateral intervals.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
