Definitions
- the invention relates to a device for inspection and maintenance of rotor blades and / or the tower surface of large wind turbines, in particular off-shore systems.
- the rotor blades Due to wear, fatigue or possible damage, for example by colliding birds, the rotor blades, but also the surface of the turbine wind turbine tower, must be regularly checked and maintained. Also, a regular cleaning of the rotor blades is often desired. This is particularly important for off-shore wind turbines due to size and environmental conditions, e.g. Wind and waves, at sea is a problem.
- large plants have a tower height of about 100 m or more, with the lower 80 m cylindrical with a diameter of 4.30 m are formed in order to transport the tower parts for mounting on roads can.
- the upper 20 m are tapered and taper to a diameter of about 2.80 m.
- Off-shore systems regularly have even larger dimensions.
- the rotor blades of the turbines are bent forwards to compensate for bends due to the wind load, so that in the pitch position at the outermost point of the rotor blade distances of 8-9 m from the tower to the rotor blade tip are to be overcome.
- a type of suspension is carried out with at least three ropes in stable equilibrium at the hub of the rotor and the tower.
- the ropes must be lowered hanging from the rotor hub during installation in order to hang them on the ground in the climbing equipment of the stages.
- the disadvantage must be disassembled and implemented when changing the rotor blade stage including rope guide, otherwise the ropes collide with the rotor blade.
- the suspension of the ropes on the rotatable nacelle is carried out in indifferent equilibrium with manually or automatically adjustable load balancing.
- a maintenance platform which also includes the rotor blade through straight working webs and hoist cables which are attached to the nacelle is lifted.
- the tilting moment of the basket is not compensated by balancing or sliding masses, but by a one-sided, vertically movable on the tower carriage and a single, open-sided clamping pliers, which enclose the tower and compensate for the differences in diameter over the length of the rotor blade. Since this solution is not described in detail, the compensation of about 2 m diameter difference of the tower and the realization of the necessary closing force in the illustrated arrangement and the function of the rollers transverse to the direction of force, especially when climbing, technically unsolved.
- WO 03/048569 A2 an unmanned device for carrying out cleaning work is described, which i.a. is firmly guided on rails on rails. According to the description of this maintenance device is connected to a fixed connector with the tower, which serves the vertical propulsion, while the cleaning device covers the rotor blade and is also guided by this.
- a solution described in DE 199 09 698 A 1 includes a ground-based system, similar to a lifting platform, on the folding mast of a cabin is fixed, which surrounds the rotor blade and is guided by this. Disadvantages are the high wind sensitivity and the high chassis and body dimensions. For off-shore systems, the use of such a solution with a closed, large and heavy cabin on the limited platform area is not practical.
- a solution described in DE 10 2005 053 782 A 1 consists of tangentially arranged, tensionable and displaceable trusses which, together with a lifting mechanism, form a climbing-capable device for carrying out work on tall slender structures.
- Disadvantage of this system is the complete system failure in case of failure of a pressing element located in the corners. In this case, the entire stage must be dismantled with a crane.
- the unskilled extensible platform can make the rotor blades only selectively accessible.
- the object of the present invention is to propose a device for inspection and maintenance of rotor blades and / or the tower surface of large wind turbines, especially off-shore installations, which is simple and inexpensive, and a safe driving the wind turbine even in poor environmental conditions, such as strong wind or rain, allows, with a guide on the rotor blade is not desired because of the risk of damage.
- the proposed device should be flexible on different types of wind turbines, in particular different tower sizes and - be used cross-sectional areas, by means of the device each point on the rotor blade to be reached.
- the device for inspection and maintenance work on rotor blades and / or the tower surface of large wind turbines, in particular off-shore installations has a guide and lifting unit for fixing on and for vertical movement along the tower.
- the guide and lifting unit has at least two rings surrounding the tower. Distributed on the circumference of the rings, these each have at least four or more telescopic trusses with active units.
- the number of trusses depends on the operating load and the mission.
- the trusses are telescopic in the direction of the axis of the wind turbine tower, the drive units move the trusses and press for fixing to the surface of the tower.
- the static design is such that in case of failure of a drive unit, the frictional force of the remaining still sufficient for a Abkletter memori. Due to the telescoping, the conicity of the tower is also compensated, and also a wide variety of tower cross sections can be negotiated.
- the trusses in addition to a sensor and safety technology to control the Anpressvorgange
- the rings are interconnected by lifting devices. By alternating clamping and lifting the climbing process takes place, whereby always a ring ensures a firm grip on the tower.
- the radially arranged telescopic traverses simultaneously center on the tower. After pressing the telescopic traverses and reaching the required holding force of a ring, the telescopic crossbeams of the second ring are released by a safety control and the lifting devices depending on the direction of movement off or retracted.
- the device has a cantilevered, multi-unit articulated boom, which is attached via a hinge to the guide and lifting unit.
- This advantageously has only a small wind attack surface.
- the links of the articulated arm are moved and stabilized by drive elements.
- the articulated arm has a stabilized by a drive element articulation to the lifting and guiding unit.
- the articulated arm also has a low mass, which minimizes the leverage in the linkage.
- the kinematics of the articulated arm ensures horizontal movements of the work basket, which can drive off by means of drive elements, such as hydraulic cylinders or spindle drives, the profile line of the rotor blade, regardless of its position, without having to guide the rotor blade.
- the wind attack surface can be minimized in the short term, so that in contrast to cable-guided stage areas in gusts or turbulence dangerous situations are avoided.
- the connection between the towering to be braced on the tower, climbing rings and the horizontally movable platform allows the construction of the maintenance device without connection to parts of the machine house or the rotor and in the lowered and folded state in off-shore installations as a fixed installation during the Operation of the wind turbine at the tower base remain.
- the upper ring preferably has a working platform which has exit positions for passage into working baskets of the articulated arms. Maintenance personnel can advantageously examine the entire tower surface on the work platform.
- the multi-articulated articulated boom at its outer end to a work basket and / or a connection unit for technical equipment for inspection or cleaning.
- the drives of the telescoping traverses are preferably electric or hydraulic linear drives.
- the telescopic trusses on their tower ends adhesive pads to increase the friction between traverse and tower and thus to ensure a secure fit.
- These are preferably special elastomers, e.g. Polyurethanes or special rubber compounds.
- the rings of the lifting and guiding unit consist in their circumference of form-locking interconnected, detachable segments.
- This segmentation of the rings has several advantages. So the ring segments are very easy to transport.
- the rings and thus the device can be adapted to different tower dimensions and geometries by providing more or larger segments for a ring and thus the ring encloses a larger diameter.
- there is the possibility between the segments additional segments in the form of extensions or wedge-shaped flanges to introduce the angle change, which further increases the adaptability.
- the segments are interconnected by bolts and / or screw flanges.
- the upper ring preferably has a working platform for maintenance personnel, advantageously with a railing. The maintenance staff can thus reach all points of the tower surface and the rotor blade surface and thus carry out all inspection, maintenance and cleaning.
- each segment preferably has a telescoping traverse with a drive unit.
- identical modules one segment with a telescoping crosshead
- rings for a wide variety of towers.
- To adjust the curvature of a ring then e.g. wedge-shaped intermediate pieces are inserted between the segments.
- Ring lines electrical and / or hydraulic) for connecting the drive units and their control are advantageously provided in the segments, which are connected during assembly of the segments.
- the trusses can be firmly integrated into the segments or attached with detachable connections to the segments.
- a segment is a tie rod.
- An alternative embodiment of the device for inspection and maintenance work on rotor blades and / or the tower surface of large wind turbines, in particular off-shore systems also has a guide and lifting unit with at least one ring, which has at least four telescoping traverses.
- the telescopic trusses have at their tower ends vertically rolling guide rollers.
- this alternative embodiment has a cantilevered, multi-joint articulated boom which is attached via a hinge to the guide and lifting unit.
- the guide and lifting unit is vertically movable by cables which are connected to the machine house of the wind turbine.
- the device has a control unit for controlling the drive elements of the traverses and the articulated arm and the lifting elements.
- inspection technology and / or a cleaning unit are arranged at the outer end of the articulated arm and / or further maintenance technology, which can also be controlled by the control unit.
- the inspection unit may be, for example, a digital camera or ultrasound, radar or X-ray technology that stores images of the surface of the tower / rotor blade surface.
- the control unit may also store data on the surface geometry of the wind turbine which the control system uses to control the movement of the device.
- a sensor is connected to the controller, which transmits environmental parameters such as wind strength and direction. This ensures safe automatic operation. Due to the low cost of a device according to the invention this, especially in off-shore systems, permanently remain on the tower and perform a regular inspection / cleaning automatically, for example, if power generation due to low wind strength is limited.
- the device preferably has a transmitting / receiving unit for communication with a further transmitting / receiving unit.
- a transmitting / receiving unit for communication with a further transmitting / receiving unit.
- FIG. 1 shows the side view of a wind power plant with a device according to the invention
- FIG. 2 shows a schematic top view of the device in working position in the lower region of the rotor blade
- FIG. 3 shows a schematic top view of the device in working position in the upper region of the rotor blade
- Figure 4 shows the side view of a lifting and guiding unit on the tower
- Figure 5 is a plan view of a lifting and guiding unit on the tower.
- Figure 1 shows the side view of a wind turbine with a machine house 2, a tower 5 with a tower axis 51 and a rotor blade 1 in the pitch position.
- a device according to the invention is shown in three positions, namely once in the region of the rotor blade tips 81, once in the knee region of the rotor blade 82 and once in the hub region of the rotor blade 83.
- the required different lengths of the articulated arm 3 are clearly visible, so the distance between the device 82 and the rotor blade 1 in the knee area is very low, in contrast, in the region of the tip of the rotor blade 1 about 8 m to bridge through the device 81.
- FIG. 2 shows a lifting and guiding unit 4 of the device already shown in FIG. 1, on the upper ring of which a work platform 6 having a railing is arranged.
- the lifting and guiding unit 4 is located around the area of the rotor blade tip, where the rotor blade, not shown, has a cutting surface 14.
- the articulated arms 3 consist of an outer articulated arm 32 and an inner articulated arm 31, which are connected via a hinge 36.
- the inner articulated arm 31 is connected via a further joint 35 with the lifting and guiding unit 4.
- a work basket 33 is attached at the end of the outer articulated arm 32. This attachment can also be articulated.
- the work platform 6 has two exit positions 34 from which maintenance personnel can transfer to the work baskets 33.
- the inner articulated arms 31 and the outer articulated arms 32 are moved at their joints 35 and 36 via linear actuators 37.
- Figure 3 shows the top view of the device for inspection and maintenance of Figure 1 and 2 at the height of the hub portion of the rotor blade, where the Thomas Structurel3 is approximately circular in shape. There are two articulated arms 3 are attached via joints 35 on the guide and lifting unit, which make it possible to reach the entire Thomas Structurel3 of the rotor blade. On the not visible in the figure 3 upper ring, the working platform 6 is arranged.
- Figure 4 shows the side view of a lifting and guiding unit 4 on the tower 5. Below is the lower ring 41 and above, connected by lifting units 47, the upper ring 42. In addition, the height of the upper ring 42 is shown with extended lifting units 47, whereby the maximum lifting height 48 results.
- the plan view of the lifting and guiding unit 4 in Figure 5 shows this once in the lower part of the tower 5, where this has a diameter of 4.30 m and once in the upper part of the tower 5, where this is a much smaller diameter of 2, 80 m.
- the upper ring 42 as well as the not visible here lower ring, are divided into segments which are connected to each other via screw flanges 44.
- the ring In the region of the rotor blade (which can not be seen in FIG. 5), the ring consists of a pull rod 7. This is relevant in particular in the knee region (12 in FIG. 1) due to the small thickness of the pull rod. Since the diameter of the rings 41 and 42 can not be reduced during driving, there is the problem in the knee area (where the tower 5 is already tapered) that there is little space between the device and the rotor blade. This can be countered by the use of a pull rod 7 by their small thickness.
- the rings are modular. In FIG.
- modules 9 are very flexible because between the modules 9 extensions, or wedge-shaped flanges can be used for angle change.
- the modular construction thus advantageously results in a modular system with which lifting and guiding units for a wide variety of tower dimensions and cross-sectional areas can be easily manufactured.
