Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The embodiment provides a double wind wheel power generation device which can be used on water or land. Referring to fig. 1 to 5, the double wind wheel power generation device mainly includes: mount 10, generator module 20, front rotor 30, and rear rotor 40.
The installation table 10 may be a concrete tower or a metal tower, and is used for supporting the generator module 20, so as to ensure the stability of the operation of the generator module 20 and the front wind wheel 30 and the rear wind wheel 40 arranged on the generator module 20.
The generator cabin 20 is arranged on the mounting table 10; a power generation device for generating power is arranged in the mounting table 10 or the generator cabin 20; the front wind wheel 30 and the rear wind wheel 40 may both be in driving connection with the power plant, such that the front wind wheel 30 and the rear wind wheel 40 convert mechanical energy into electrical energy via a generator when rotating.
The front wind wheel 30 is arranged in the generator cabin 20 and comprises three front blades 31 distributed in a circumferential array, and the chord length of each front blade 31 is gradually increased from the blade root to the blade tip and then gradually decreased; the rear wind wheel 40 is arranged in the generator cabin 20 and comprises two rear blades 41 distributed in a circumferential array, and the chord length of each rear blade 41 is gradually increased from the blade root to the blade tip and then gradually decreased; thus, the front blades 31 and the rear blades 41 are identical in shape, mainly differing in size, specifically, the diameter of the front wind wheel 30 is D1, and the diameter of the rear wind wheel 40 is D2, wherein d2= (0.78-0.85) D1.
In the above-described configuration in which the front wind wheel 30 is provided with 3 front blades 31 to obtain more wind energy and the rear wind wheel 40 is provided with two rear blades 41 to capture the air flow flowing from the front wind wheel 30, the diameter ranges of the front wind wheel 30 and the rear wind wheel 40 are selected to satisfy d2= (0.78-0.85) D1, thereby maximizing the overall power generation efficiency of the twin wind wheel power generation device.
Therefore, the two main characteristics of the scheme that the power generation efficiency of the double wind wheel power generation device is improved are that: (1) the front wind wheel 30 is provided with 3 blades, the rear wind wheel 40 is provided with two blades, (2) the diameter ranges of the front wind wheel 30 and the rear wind wheel 40 meet d2= (0.78-0.85) D1.
The skilled person in this application obtains through experiments that, under the condition of setting three blades of the front wind wheel 30 and two blades of the rear wind wheel 40, if D2 is smaller than 0.78D1, or D2 is larger than 0.85D1, the overall power generation efficiency of the front wind wheel 30 and the rear wind wheel 40 will be reduced to a certain extent.
In addition, the rear wind wheel 40 has lower manufacturing cost compared with the rear wind wheel 40 provided with two blades and 3 blades, and the installation and transportation cost is also reduced, so that the construction efficiency of the double wind wheel power generation device can be improved, and the construction period can be shortened.
In some embodiments, the ratio of the diameters of front rotor 30 and rear rotor 40 may be: d2 = 0.79D1, d2= 0.8D1, d2= 0.82D1, and the like.
In some embodiments, the chord length of the front blade 31 increases from the root to the tip by 1/7-1/5 of the total length of the front blade 31; the chord length of the trailing blade 41 increases from the root to the tip by 1/7 to 1/5 of the total length of the trailing blade 41. The extent of the chord length of the front blade 31 from the root to the tip of the blade is also reflected in fig. 6. Within this range, both the front wind wheel 30 and the rear wind wheel 40 have high working efficiency.
Referring to fig. 3, the front blade 31 has a chord length L1, and thicknesses S1, L1 and S1 are located at the same position of the front blade 31, and the relative chord length of the front blade 31 is equal to S1/L1, with the relative chord length of the front blade 31 ranging from 15% to 40%. Of course, the relative chord lengths of the different positions of the front blade 31 are different. Referring to fig. 6, it can be seen that the relative chord length of the leading blade 31 increases gradually and then decreases gradually, with the increase being faster than the decrease.
In some embodiments, the trailing blade 41 has a chord length L2 and a thickness S2, L2 and S2 being located at the same location of the trailing blade 41, the relative chord length of the trailing blade 41 being equal to S2/L2, the relative chord length of the trailing blade 41 being in the range of 15% -40%. Since the rear blade 41 and the front blade 31 are of the same type, the view of the rear blade 41 is not shown any more, as will be understood by those skilled in the art with reference to the front blade 31.
In some embodiments, the thickness of the leading blade 31 tapers in a direction from the root to the tip; the thickness of the trailing blade 41 tapers in the direction from the root to the tip. Thereby ensuring the firmness of the installation of the front blade 31 and the rear blade 41 and being more stable during rotation.
In some embodiments, front rotor 30 includes 3 front blades 31 and rear rotor 40 includes 3 rear blades 41. That is, the double wind wheel power generation device in this embodiment adopts the form of 3 blades in front and rear.
In some embodiments, the spacing between front wind wheel 30 and rear wind wheel 40 is a, which ranges from 0.25 to 0.3 times the diameter of front wind wheel 30. In this range, on the basis of ensuring stable installation of the front wind wheel 30 and the rear wind wheel 40, the influence of the front wind wheel 30 on the rear wind wheel 40 can be further reduced, thereby improving the overall power generation efficiency of the double wind wheel power generation device.
In some embodiments, the power generation device is a dual rotor generator, the shaft of front wind wheel 30 is drivingly connected to a first rotor of the dual rotor generator, and the shaft of rear wind wheel 40 is drivingly connected to a second rotor of the dual rotor generator. That is, only one generator may be disposed in the generator module 20, and the front wind wheel 30 and the rear wind wheel 40 respectively drive different rotors of the generators to operate, thereby reducing the weight of the generator module 20 and reducing the difficulty of installing the double wind wheel power generation device.
In some embodiments, the axis of the rotation axis of the front wind wheel 30 coincides with the axis of the rotation axis of the rear wind wheel 40.
In some embodiments, the mounting table 10 is a hollow concrete tower.
In some embodiments, the material of the leading blade 31 and/or the trailing blade 41 is a fiberglass composite. The material can ensure the structural strength, has lighter weight, is favorable for installation and transportation, and also ensures the stability in the power generation process to the greatest extent.
