Based on the rotational speed data of the detection signal, the control unit controls the rotational speed of the hydraulic motor to be adjusted to a rated rotational speed range. BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following description and detailed description, which, as those skilled in the art, can be modified and modified by the teachings of the present invention. The spirit and scope of the invention are not departed. Referring to Fig. 1, Fig. 1 is a schematic view showing the structure of a wind power generator according to an embodiment of the present invention. The present invention discloses a wind power generation apparatus 100. The wind power generation apparatus 100 includes a wind turbine compartment 200, a tower base 3, a tower 400, a generator set 5A, and a hydraulic transmission unit 600. The invention adopts the way that the hydraulic transmission group 600 drives the generator to operate, instead of the way the coaxially driven generator operates, and thus the genset 500 can be moved from the high-altitude to the ground by the wind turbine cabin 2' The volume and weight of the nacelle 200 can also reduce the difficulty of constructing the wind power generation device 100 and reduce the maintenance cost of the wind power generation device 100 after operation. In a specific embodiment of the present invention, the wind power generation device 100 can be a large offshore wind turbine, wherein the tower 300 is fixed on one of the ground platforms 301, and has a first accommodating space 302. . The tower 400 is located between the tower 300 and the fan compartment 200 and is supported by the wind turbine compartment 200 in the sky, and likewise has a second accommodating space 401 therein. The fan compartment 200 has a third accommodating space 201, a fan body 202 and a transmission shaft 203. The fan body 202 is located outside the fan compartment 200 and is coaxially pivotally connected to a transmission shaft 203 in the third accommodating space 20 1 . The genset 500 is located at least in the first accommodating space 302. The genset 500 is located at least on the ground, in the first accommodating space 302 or outside the tower 300. The embodiment is not limited to the present invention. Only the first accommodating space 302 is set. The hydraulic transmission unit 600 is disposed across the fan compartment 200 and the tower 300, and is coupled to the transmission shaft 203 and the generator set 500, and includes a hydraulic pump 601 and a hydraulic motor 602. The hydraulic pump 601 is located in the driven fan compartment 200 and coaxially coupled to the drive shaft 203. The hydraulic motor 602 is located in the tower 300 and is coaxially coupled to the generator set 500. In addition, the hydraulic pump 601 and the hydraulic motor 602 have at least two tubes 603 and 604. The tubes 603 and 604 are located in the second accommodating space 401 and are respectively connected to the hydraulic pump 601 and the hydraulic motor 602. One of the tubes 603 It is equipped with liquid (including hydraulic oil and hydraulic fluid, etc.) that can be hydraulically driven by hydraulic pump 601. The other pipe body 604 is provided with a liquid (the liquid of the above-mentioned pipe body 603) which can be returned to the hydraulic pump 601. Thus, when the fan body 202 is driven by the wind to drive the transmission shaft 203, the transmission shaft 203 drives the hydraulic pump 601 to operate, and the hydraulic pump 601 drives the liquid to pass through the column 400 to the hydraulic motor 602 to drive the hydraulic motor 602 to rotate. In this way, the hydraulic motor 602 can drive the generator set 500 to operate to generate electricity. Since the voltage generated by the genset 500 must be stable, a stable voltage source can be generated. Therefore, in order to prevent the genset 500 from producing an unstable voltage source, the external power system 700 is electrically connected to the genset 500. If the load is too large (for example, transformer or current collector), the speed of the hydraulic motor 602 to drive the genset 500 to rotate must be quite constant, especially in accordance with a rated speed range (usually the standard rated speed ± 5%). To this end, reference is made to Fig. 2, which is a block diagram of the wind power generator of the present invention in this embodiment. The wind power generator 100 has a speed detector 303 and a control unit 800. The control unit 800 is, for example, a computer for monitoring software or an embedded system, and is not limited to its location. The hydraulic motor 602, the genset 500 and the rotational speed detector 303 are connected, and the voltage data generated by the operation of the genset 500 is obtained. The speed detector 303 is located between the hydraulic motor 602 and the genset 500, and can immediately return a detection signal having a hydraulic motor 602 to drive the rotation of the genset 500 to the control unit 800. The control unit 800 controls the rotational speed of the hydraulic motor 602 according to the rotational speed data of the detection signal to be adjusted to the rated rotational speed range. In addition, the control unit 800 is further electrically connected to a braking mechanism 801. The braking mechanism 801 is disposed on the transmission shaft 203 to resist the rotation speed of the transmission shaft 203, thereby reducing the rotation speed of the hydraulic motor 602. Thus, when the rotational speed of the hydraulic motor 602 is greater than a working rotational speed range (the range of which includes the rated rotational speed range, such as 500-3000 rpm), the control unit 800 controls the braking mechanism 801 to lower the rotational speed of the hydraulic motor 602 to make it low. In the working speed range. Conversely, when the rotational speed of the hydraulic motor 602 is less than a range of operating speeds, the connection of the genset 500 of the control unit 800 to the power system 700 is shut off. The definition of the coaxial connection of one element to another element is such that the element and the other element are on a shaft that can rotate in synchronism, or the element utilizes intermeshing gears to simultaneously rotate the other element. The technical features disclosed in the above embodiments of the present invention are not intended to limit the present invention, and those skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
