Assembly comprising a first and a second upright section and a fixation
The present invention relates to an assembly, comprising a first and a second upright section, and a fixation configured to fix the first and the second upright section.
The present invention is particularly suitable for offshore applications, e.g. for connecting a wind turbine to a monopile, a wind turbine to a transition piece, a transition piece to a monopile, as well as between sections of a monopile or wind turbine.
According to prior art applications in offshore, the upright sections of such assemblies are provided with flanges which are connected using bolts of significant size. Currently M72 bolts are used for connecting a wind turbine tower to a monopile or transition piece. In a first step, these bolts are electrically tightened with 8.000 Nm. In a second step, the preload is increased with hydraulic tools to 22.000 Nm. The bolts itself are heavy and the tools for tightening the bolts is also heavy and hard to handle.
It appears that the actual preload on the bolls after some settling time is hard to predict and control, and may vary significantly. Although it is not exactly clear which factors influence the torque-tension relationship of the bolts, it may be concluded that installing the bolts using a “constant torque” method does not achieve satisfying results. The preload on the bolts must be regularly checked and adjusted, periodically requiring significant maintenance work.
Furthermore, the bolts are arranged all around the circumference of the flanges, leaving only a very limited gap between adjacent bolts. A connection using flanges with bolts is insufficiently scalable to meet the ever increasing demands resulting from even larger wind turbines and greater depths as sea where they are installed.
A tower connector having a connector assembly for joining a tower to a base structure, wherein the axial alignment of the tower to the base structure is adjustable, is known. In order to permit tilt adjustment, the connection is embodied as a ball and socket joint. In order to act as a ball and socket joint, mating surfaces between connector portions of the connector assembly have to provide an interface permitting tilt adjustment. It is exactly this adjustment, which is obtained with flat mating surfaces, which renders the application unsuitable for fixing connector portions once aligned. If the flat mating surfaces are / remain not perfectly parallel to each other, the contact area between them is formed by a contact line instead of a contact surface. Such a contact line will not be able to withstand the forces experienced in practical offshore wind turbine situations. The tilt adjustment via a ball and socket type of connection also negatively influences scalability of the design.
An object of the present invention is to provide an assembly, that is improved relative to the prior art and wherein at least one of the above staled problems is obviated.
Said object is achieved with the assembly according to the present invention, comprising a first and a second upright section, each upright section comprising a longitudinal axis, a fixation configured to fix the first and the second upright section, wherein at least one of the first and the second upright section comprises a body that is configured to be engaged by the fixation, and wherein the fixation comprises an abutment and a radially displaceable actuator. The actuator is radially displaceable with respect to the longitudinal axis of the upright section that comprises the actuator.
The body that is engaged by the fixation is clamped between the abutment and the radially displaceable actuator, thereby reliably fixing the first and the second upright sections to each other. Additional fixation means, such as bolts according to the prior art, are redundant. Also, the body may be less bulky than a flange comprising through holes to accommodate a bolt. As a result, the assembly according to the invention, requires less material, is therefore more compact and lighter, and also more elegant. Whereas thick parts need to be forged, smaller parts may also be rolled, possibly allowing the upright sections to be formed with alternative and more attractive manufacturing methods. Also, the assembly according to the invention is scalable, providing the opportunity to arrange multiple fixations in axial direction of the upright sections.
A further advantage of the proposed assembly, is that it may be applied for connecting sections under the waterline. On the one hand, longitudinal sections of a limited length may be used, allowing smaller ships to transport them to a desired location for an offshore construction. On the other hand, the proposed assembly due to it’s option to be arranged under the waterline, also allows offshore constructions to be arranged at deeper locations than was possible with the conventional bolted flanges.
The successively tightening the bolts of a bolted flange - which are typically tightened in multiple steps, as mentioned above - is very time consuming and labor-intensive. The proposed assembly is less labor-intensive and time consuming than an connection having bolted flanges.
Further preferred embodiments are the subject of the dependent claims.
In the following description preferred embodiments of the present invention are further elucidated with reference to the drawing, in which:

Figure 12 is a perspective view of an assembly according to a fourth embodiment;
Figure 13 is a cross sectional view of the assembly of Figure 12; and
Figure 14 is a top view of a ring-shaped actuator of the assembly of Figure 13.
An example of an offshore construction comprising multiple connections C where an assembly according to the invention may be applied is shown in Figure 1. An offshore wind turbine tower 1 is supported by a supporting base structure 2 which is in Figure 1 embodied as a monopile 3 with a transition piece 4. The skilled person will understand that similar connections are present for alternative supporting base structures 2, such as (not shown) jackets.
The connections C may be applied between separate sections 8 of the monopile 3, between the monopile 3 and the transition piece 4, between the transition piece 4 and the turbine tower 1, and between sections 9 of the turbine tower 1.
During use, a wind turbine 5 will be oriented such that the rotor blades 6 are optimally driven by the available wind power. The rotor blades 6 drive a (not shown) generator in the nacelle 7, wherein the generator generates electricity. The wind turbine 5 causes alternating loads on any connection C in the construction, and dependent on the wind direction, specific parts of the connection C have to absorb most of the loads.
According to the prior art (Figure 2), an assembly 10 configured to connect a first upright section 11 and a second upright section 12 normally comprises flanges 13, 14. These flanges 13, 14 are provided with through holes 15, 16, which are aligned. A bolt 17 and nut 40 assembly is then arranged through the aligned through holes 15, 16, and used to clamp the flanges 13, 14 to each other. As already described, currently M72 bolts 17 are used for connecting a wind turbine tower 1 to a monopile 3 or transition piece 4. The bolts 17 itself are heavy and the tools for tightening the bolts 17 are also heavy and hard to handle. Moreover, the preload on the bolts 17 must be regularly checked and adjusted, periodically requiring significant maintenance work.
In order to accommodate the through holes 15, 16 and withstand the clamping force by the bolts 17, the flanges 13, 14 need to be relatively thick in both axial and radial direction.
The assembly according to the present invention also comprises a first upright section 18 and a second upright section 19. Each longitudinal upright section 18, 19 comprises a longitudinal axis 21, 22. The assembly further comprises a fixation 20 configured to fix the first 18 and the second upright section 19. However, instead of bolted flanges, the fixation 20 is embodied as an abutment 23 and a radially, i.e. transverse to a longitudinal axis 21, 22, displaceable actuator 24. At least one of the first 18 and the second upright section 19 comprises a body 25 that is configured to be engaged by the fixation 20.
By using a fixation 20 that renders conventional bolts 17 abundant, there is no need for through holes 15, 16 anymore. Consequently, the body 25 according to the invention can be less bulky than a conventional flange. This results in a more elegant design, requiring less material and possibly also allowing alternative manufacturing methods. Whereas thick parts need to be forged, smaller parts may also be rolled.
In the shown embodiments, the longitudinal axes 21, 22 of the first 18 and the second upright section 19 are at least parallel. In Figure 3, the axes 21, 22 coincide, which is the preferred situation.
The abutment 23 is preferably part of the other of the first 18 and the second upright section 19. In the shown embodiments, the body 25 is part of the first upright section 18, and the abutment 23 is part of the second upright section 19.
The abutment 23 abuts against a support surface 26 of the body 25. This support surface 26 is oriented in radial direction with respect to the longitudinal axis 21 of the first longitudinal upright section 18.
The body 25 comprises a radially extending protrusion. Preferably, body 25 comprises a flange. A flange, being a protrusion that extends along the circumference of the respective upright section 18, can, in contrast to discrete protrusions, be engaged anywhere along the circumference. Therefore, the relative orientation between the first and second upright section
18, 19 is less or not critical if the body 25 is a flange.
The actuator 24 is preferably part of the other of the first 18 and the second upright section 19. In the shown embodiments, the body 25 is part of the first upright section 18, and the actuator 24 is part of the second upright section 19.
Preferably, both the abutment 23 and the actuator are part of the other of the first 18 and the second upright section 19. In the shown embodiments, the body 25 is part of the first upright section 18, and the abutment 23 and the actuator 24 are both part of the second upright section 19. In this way, the second upright section 19 partly encloses the body 25 of the first upright section 18. Using actuator 24, the body 25 is clamped between the abutment 23 and the actuator 24, thereby providing a reliable fixation between the first 18 and second upright section
19. Furthermore, additional fixation means, such as bolts 17 according to the prior art, are redundant. Also, the body 25 may be less bulky than a flange 13, 14 comprising through holes 15, 16 to accommodate a bolt 17.
The actuator 24 has a contact surface 29 that is configured to engage a mating engagement surface 28 of the body 25. The support surface 26 and the engagement surface 28 correspond to each other in order to form a mating interface.
The support surface 26 and the engagement surface 28 are arranged on opposite sides of the body 25. The body 25 is a tolerance critical part of the first upright section 18. The body 25, and the support surface 26 and engagement surface 28 thereof, need to correspond to the dimensions of the fixation 20.
The contact surface 29 of the actuator 24 and the engagement surface 28 of the body 25 comprise a corresponding chamfer. When the chamfer of the contact surface 29 and the chamfer of the engagement surface 28 are substantially equal, are reliable mating interface is obtained. Due to the chamfer, a radial displacement of the actuator 24 is converted to a clamping action, wherein the body 25 is clamped between the abutment 23 and the contact surface 29 of the actuator 24.
The chamfer of the contact surface and/or the chamfer of the engagement surface 28 has an angle of less than 25°, preferably less than 20°, more preferably less than 15°, and most preferably equal to or less than 10°. By providing a chamfer with a relatively flat angle, it is possible to apply a relatively high axial clamping force Fc with a relatively small radial actuation force Fa. The angle of the chamfer functions as a lever.
A high axial clamping force provides the advantage that the assembly is less susceptible for load variations. This is best understood when compared to how a bolted joint carries a direct load. An adequately pretensioned bolt can survive in an application that an untightened, or loose bolt, would fail in a matter of seconds. In short, the effect of an applied load first decreases a clamp force of the bolt, before the bolt starts to actually ‘feel’ any of the applied force.
A further advantage of a chamfer with a relatively flat angle follows from a force decomposition (Figure 4B). When the fixation 20 clamps the body 25 between the abutment 23 and the actuator 24 of the fixation 20, the clamping force Fc will try to pivot the actuator 24 around the pivot points 30 and 31. This results in friction in the interface between the contact surface 29 of the actuator 24 and the engagement surface 28 of the body 25, wherein:
ffriction — k- * ^pressure and μ is the friction coefficient. If the chamfer has a relatively flat angle, the force Fd will remain smaller than the friction forces in points 30 and 31. As a result, the clamping action will not be able to displace the actuator 24 away from the body 25. In this way, a secure fixation is guaranteed.
The radially displaceable actuator 24 is arranged in a radial bore 32 of the other of the first 18 and the second upright section 19. The actuator 24 is preferably arranged in said bore with a sliding fit or press-fit. In the embodiment shown in Figure 4, two seals 33, e.g. o-rings, seal the actuator 24 in the bore 32.
As shown in Figures 3, 5 and 6, multiple radially displaceable actuators 24 are arranged along the circumference of the other of the first 18 and the second upright section 19. Using multiple radially displaceable actuators 24, the clamping force for fixing the first 18 and the second upright section 19 is distributed. This on the one hand increases the reliability of the assembly by distributing the force over multiple surfaces. On the other hand, it also distributes the positon of the clamping surfaces over the circumference. This is especially advantageous for wind turbines, which causes forces which have an orientation that is dependent on the wind direction.
Although the skilled person could envisage alternative ways of radially displacing the actuator 24, the one or more than one actuator 24 is preferably hydraulically displaced. This allows for a further preferred embodiment, wherein a hydraulic fluid used for displacing the actuator 24 remains in a pressure chamber 34.
The pressure chamber 34 may comprises a one-way inlet valve configured to introduce the hydraulic fluid into the pressure chamber 34.
In a further preferred embodiment, the hydraulic fluid is configured to cure and thereby transform into a substantially solid state. In this way, the solidified hydraulic fluid forms a substantially rigid securing, preventing that the actuator 24 may move back towards the pressure chamber 34.
Figures 5 and 6 show a further embodiment, wherein at least one of the first 18 and the second upright section 19 comprises at least one additional body 25’ that is configured to be engaged by an additional fixation 20’. The additional fixation 20’ comprises at least one additional radially displaceable actuator 24’. The abutment 23 of the second upright section 19 is also the functional abutment of the additional fixation 20’. The clamping force applied by the actuator 24’ on additional body 25’ is transferred via the wall of the first upright section 18 towards body 25 that has a support surface 26 that engages abutment 23.
The body 25 and the additional body 25’ are arranged at an axial distance 35. This provides a scalable design.
In the embodiment of Figures 5, 6, the fixation 20 and the additional fixation 20’ each comprise multiple radially displaceable actuators 24, 24’, wherein the actuators 24 of the fixation 20 are arranged in a staggered arrangement with respect to the actuators 24’ of the additional fixation 20’.
In all shown embodiments, at least the upright section 18 that comprises the body 25, further comprises a hammering surface 27. As mentioned before, the body 25 is a tolerance critical part of the first upright section 18. After all, the body 25, and the support surface 26 and engagement surface 28 thereof, need to correspond to the dimensions of the fixation 20. By providing a separate hammering surface 27, that is configured to drive the respective upright section 18 into the ground with a ram, it is prevented that the body 25 with support surface 26 and the engagement surface 28 is hammered on. Therefore, the tolerances of the body 25 can be maintained, thereby safeguarding a reliable fixation between the first 18 and the second upright section 19.
In the embodiment of Figures 7-11, the hammering surface 27 is arranged on a wall 36 extending from the upright 18 past the support surface 26. The hammering surface 27 being arranged at another level than then support surface 26, eliminates the risk of the tolerance sensitive support surface 26 being hammered on by a ram.
In Figures 7-11, successive steps of assembling an assembly according to a third embodiment of the present invention are shown.
In Figure 7, the first 18 and second upright section 19 are shown in a preassembled state, at a distance from each other. In the embodiment shown, both of the first 18 and the second upright section 19 comprise one or more than one chamfered guide surface 37, 38. The axially chamfered guide surfaces 37 of the first upright section 18, and the axially chamfered guide surface 38 ofthe second upright section 19, facilitate guidance of the upright sections 18, 19.
In Figure 8, the abutment 23 of the second upright section 19 abuts against, and is supported by, the support surface 26 of the first upright section 18.
In Figure 9 the actuator 24 is radially displaced, wherein the contact surface 29 of the actuator 24 engages the engagement surface 28 of the body 25 of the first upright section 18. Due to the chamfer of the contact surface 29 and the engagement surface 28, a clamping action is performed.
In Figure 10, the body 25 is clamped between the abutment 23 and the actuator 24, thereby providing a reliable fixation between the first 18 and second upright section 19.
Finally, in Figure 11, a seal 39 is arranged between the wall 36 extending from the first upright section 18 past the support surface 26 and the second upright section 19. If an hydraulic fluid is used for displacing actuator 24, it preferably remains in pressure chamber 34. In a preferred embodiment, the hydraulic fluid solidifies once cured. The solidified state is shown in Figure 11. Alternatively, or in combination, a (not shown) one-way inlet valve may be applied.
In a not shown further preferred embodiment, the actuator 24 may be elastically pretensioned. This can be achieved by using a compressible hydraulic fluid in pressure chamber 34, or by appropriate design or material choice of the actuator 24 itself.
In the shown embodiments, the first 18 and the second upright section 19 are tubular sections. They are preferably sections of an offshore construction, such as shown in Figure
1.
A further embodiment, wherein three fixations 120, 120’ and 120” are applied, is shown in figures 12-14. Each fixation 120, 120’ and 120” comprises a ring-shaped radially displaceable actuator 124, 124’, 124”. Each ring-shaped actuator 124, 124’, 124” comprises a plurality of ring segments 140. A seal 133 is arranged in a recess 141. The operating principle of this embodiment is similar to the previously described embodiments. Therefore, a detailed description of all features is omitted here.
Although they show preferred embodiments of the invention, the above described embodiments are intended only to illustrate the invention and not to limit in any way the scope of the invention. Figure 1 shows an offshore wind turbine tower construction, but the assembly according to the invention is not limited to offshore use, nor to wind turbine applications alone.
It is remarked that in the following description of the shown embodiments, the lower upright section is denoted as the first upright section 18, and that the upper upright section is denoted as the second upright section 19. The skilled person will understand that the lower section could be interpreted as a second section 19 and the upper section could be interpreted as a first section 18 within the scope of the invention.
It should be understood that where features mentioned in the appended claims are followed by reference signs, such signs are included solely for the purpose of enhancing the intelligibility of the claims and are in no way limiting on the scope of the claims. Furthermore, it is particularly noted that the skilled person can combine technical measures of the different embodiments. For example, chamfered guide surface 37, 38 as shown for the third embodiment may also be applied for the other embodiments.
The scope of the invention is defined solely by the following claims.
