Definitions
- the invention relates to a wind turbine.
- the known wind turbines consist of a tower which carries a rotor with several rotor blades.
- a generator which generates the electrical energy, is coupled to the rotor via a transmission gear.
- Power plants with several wind turbines are also referred to as wind farms.
- the tower In order to be able to use the higher wind speed at higher altitudes, the tower should have a large construction height.
- the construction of a high tower is associated with considerable technical effort, especially since the heavy generator of the known wind turbines arranged on the tower head requires a very stable structure. Plants with an output of up to around 200 KW are built in a tubular steel structure. Larger systems use a reinforced concrete tower as the supporting structure.
- a further disadvantage of the known wind turbines is that a minimum wind speed is required to turn the rotor.
- the object of the invention is to create a wind power plant whose tower or its foundation can be constructed in a simple manner with relatively little effort.
- the power on the rotor shaft is transferred hydraulically to the generator.
- the rotor advantageously drives a hydraulic pump which is connected via pressure medium lines to a hydraulic motor driving the generator.
- the hydraulic power transmission makes it possible to place the very heavy generator on the ground in a machine house. As a result, the main load of the tower is reduced, so that an easier and less expensive design of the tower and the foundation is possible. In this way, towers with a large overall height can be erected with relatively little effort and the performance of the system increased.
- the hydraulic pumps assigned to the individual rotors can be switched to a common hydraulic motor.
- wind energy can be optimally used even at low wind speeds.
- the hydraulic pumps Pen of the individual rotors together drive a generator with the optimal speed or the optimal torque.
- the tower can be tilted from the horizontal position into the vertical position, preferably with a hydraulic drive.
- a crane for erecting the tower mounted on the floor is therefore not necessary.
- the tower is a tube construction made of tubes that run obliquely upwards with horizontal struts.
- the essentially vertical tubes of the tower consist of individual tube segments that can be assembled telescopically and are delimited by stops.
- the horizontal struts of the tubular construction form an angular frame, at the corner points of which tubular connecting pieces are provided which enclose the tubular segments and hold the vertical tubes together firmly.
- the tower can be assembled on site in the manner of a modular system from the tube segments and the angular frame.
- the individual parts can be assembled into towers of different heights. They can also be transported to the installation site with smaller vehicles. Heavy transporters for the transport of larger assembly units are therefore not necessary.
- the foundation of the tower can also be built in a simple manner. To erect the foundation, it is only necessary to drill holes in the ground into which a suitable filler material is injected.
- the wind forces acting on the tower are advantageously intercepted with lateral arms which are attached to the foundation heads.
- the cantilevers are connected at their free ends to bases, from which, in turn, foundation strands formed in the manner of a root extend into the ground.
- the number and length of the lateral support arms can be adapted to the local conditions.
- 1 is a hydraulic circuit diagram of a power plant consisting of several wind turbines
- Fig. 5 shows the detail A of Fig. 2 in an enlarged and partially sectioned representation
- Fig. 6 shows part of the foundation on which the tower is built.
- 1 shows the hydraulic circuit diagram of a power plant consisting of several wind power plants 1, 1 ', 1 ".
- the wind power plants 1, 1', 1" each have a tower 2, 2 ', 2 ", which has a rotor 3, 3', 3 "with two rotor blades 4, 4 ', 4" and a hydraulic pump 5, 5', 5 "driven by the rotor.
- each wind turbine is connected via pressure medium lines 6, 6 ', 6 "to a hydraulic motor 7, 7', 7" which drives a generator 8, 8 ', 8 ".
- the hydraulic motors assigned to the individual wind turbines are located together with the generators in a machine house next to the towers.
- the pressure medium line connecting the pressure connection of the hydraulic pump 5 to the pressure connection of the hydraulic motor 7 is designated by the reference number 9, while the line connecting the return connection of the hydraulic motor 7 to the suction-side pressure medium connection of the hydraulic pump 5 is also shown the reference 10 is designated.
- Shut-off valves 11, 11 ', 11 are provided in the pressure medium lines 6, 6', 6" between the hydraulic pumps and hydraulic motors. When the valve is open, the hydraulic pump and the hydraulic motor of each wind turbine form a closed pressure medium circuit. When the valve is closed, the pressure medium lines are shut off.
- connection valves 13, 13 being located in the connecting branches between the hydraulic pumps of two neighboring wind turbines ', 13 ", with which the hydraulic pumps of the interconnect individual wind turbines or have them separated from each other.
- the hydraulic pumps 5, 5 ', 5 can be switched from two or more wind turbines to a common generator 8, 8', 8". This is advantageous at low wind speeds or in the event of a generator failure.
- the hydraulic pumps 5, 5 'of the wind turbines 1, 1' are switched to the hydraulic motor designated by the reference numeral 7 ', while the hydraulic motor 7 is switched off.
- the hydraulic pump 5 "of the wind power plant 1" forms a separate pressure medium circuit with the hydraulic motor 7 ", since the connection valve 13 'or 13" is blocked.
- the hydraulic pump of the third wind turbine 1" can also drive the generator 8'.
- Fig. 2 shows the tower 2 of a wind turbine in a side view.
- the tower 2 is a tubular steel construction comprising three tubes 16 which converge at an upward angle and which are connected with horizontal struts 15 to form an angled frame, the tubes 16 forming the corner points and the struts 15 forming the legs of an isosceles triangle.
- the tower 2 is fastened to a foot part 17 so as to be pivotable about a horizontal axis 18.
- the foot part 17 of the tower 2 consists of three supports 19 which are connected with horizontal struts 20 to form an angularly fixed frame which stands on a foundation which is under 6 will be described in more detail.
- FIG. 3 shows a partial view of the tower 2 when the piston of the piston-cylinder arrangement 23 is retracted.
- the tubes 16 of the tower consist of telescopic tube segments 25 which can be assembled on site.
- the horizontal struts 15 are screwed and / or welded at their ends to the inner half-shells 26 of pipe clamps 27, which firmly enclose the pipes 25.
- the horizontal struts 15 together with the pipe clamps 27 form an angular frame in the form of an isosceles triangle (FIG. 4).
- FIG. 5 shows the pipe segments 25 '25 "which are connected to one another together with a horizontal strut 15 in a partially sectioned representation. Since the inner diameter of the lower pipe segment 25' is slightly larger than the outer diameter of the upper pipe segment 25", the pipe segments 25 can be push into each other, the upper tube segment 25 "also a stop 28 on the upper edge 29 of the lower pipe segment 25 'is supported. The pipe segments 25 are thus secured against axial displacement. The pipe segments 25 are secured against twisting by fitting bolts 30. The fitting bolts 30 are firmly seated in mutually aligned bores 31 of the two pipe segment ends. A second stop 32 is provided at the upper end of the lower pipe segment 25 '.
- the upper pipe segment 25 ' is thus supported with its stop 28 on the upper edge 29 of the lower pipe segment 25' and on the upper one Edge of the pipe clamp 27, while the lower edge of the pipe clamp 27 rests on the stop 32 on the outer wall of the lower pipe segment 25 '.
- the lower pipe segment 25 ' is provided with one or more longitudinal slots 33.
- Fig. 6 shows a part of the foundation on which the tower 2 is built.
- the pipe sections 19 of the foot part 17 are each fastened to a plate-shaped foundation head.
- 5 shows one of the three foundation heads 34 of the foundation.
- Steel-reinforced foundation strands 36 which are designed in the manner of a root, extend from the foundation head 34 into the base 39 in all directions.
- the lateral head 37 made of steel arranged in a star-shaped or beam-like manner extends from the foundation head 34.
- the free ends of the cantilevers 37, of which only one cantilever is shown in FIG. 6, rest on a base 38, from which, in turn, steel-reinforced foundation strands 36 formed in the manner of a root originate.
- the foundation can be built in a simple manner using the following method. First, 39 holes 40 are drilled into the subsurface, which are graded in themselves. In these holes 40 is mixed and prepared z. B. polyester concrete is pressed in under high pressure, so that the flowable concrete mass penetrates into all the gaps and cavities of the subsurface adjacent to the bores and causes a branching. The foundation heads 34 and the bases 38 of the brackets 37, which connect the upper ends of the foundation strands 36 to one another, are then cast on the substrate.

Abstract
Une installation fonctionnant à l'énergie éolienne comprend un mât (2) qui porte un rotor (3) qui actionne un générateur (8). La puissance au niveau de l'arbre du rotor est transmise au générateur de manière hydraulique. Le rotor actionne avantageusement une pompe hydraulique (5) reliée par l'intermédiaire de conduites hydrauliques à un moteur hydraulique (7) qui actionne le générateur. Le système de transmission hydraulique permet de placer le générateur (8) qui est très lourd sur le sol d'un hall de machines. L'invention permet de diminuer la charge principale du mât, de manière à pouvoir parvenir à une conception plus légère et plus économique du mât et de ses fondations. Pour les centrales qui comprennent plusieurs installations fonctionnant à l'énergie éolienne (1, 1', 1''), les pompes hydrauliques (5, 5', 5'') associées aux rotors (3, 3', 3'') individuels peuvent être commutées sur un moteur hydraulique (7, 7', 7'') commun, ce qui permet d'utiliser deanière optimale l'énergie éolienne, y compris pour des vitesses de vent réduites.
