Abstract
The invention relates to a fan. The fan comprises a blade, a hub connected with the blade, a hydraulic transmission mechanism and a synchronous generator, wherein the blade is arranged on the hub; the input end of the hydraulic transmission mechanism is connected with the output end of the hub; and the output end of the hydraulic transmission mechanism is connected with the synchronous generator. The original gear box is replaced by the hydraulic transmission mechanism, so that the power generation frequency of the synchronous generator is 50Hz, inversion is avoided, direct Internet surfing is realized, and the fan has the advantages of light weight, a few parts and high reliability and power generation quality.
Description
Technical field
The present invention relates to a kind of blower fan, relate in particular to the hydraulicdriven blower fan of a kind of employing.
Background technique
See also Fig. 1; It among the figure blower fan structure of the prior art; Comprise successively the blade 1 that connects ', wheel hub 2 ', gear-box 3 ', induction generator 4 ', inverter 5 ', blade 1 ' be installed in wheel hub 2 ' on, wheel hub 2 ' driven gear case 3 ' rotation; Drive again after gear-box 3 ' raising speed induction generator 4 ', through inverter 5 ' send Ac.
Present this blower fan structure has following shortcoming:
1. weight is big, because gear-box 3 ' be more than 50 ton, inverter 5 ' have tens tons near more than 60 tons, causes the weight of blower fan big, and the ground device fabrication cost of blower fan is high.
2. parts are many because existing this structure need adopt gear-box 3 ' with inverter 5 ', these two parts all are big parts, are two parts that go wrong the most easily in the blower fan, because parts are many, cause reliability to reduce.
3. power generating quality is bad because wheel hub 2 ' and gear-box 3 ' between be to be rigidly connected, in case input has fluctuation, influence the generator input end, power generating quality can the height instability.
Summary of the invention
The objective of the invention is to overcome the defective of existing technology and a kind of blower fan is provided, advantage in light weight, that cost is low, parts are few, reliability is high, power generating quality is good that this blower fan has.
The technological scheme that realizes above-mentioned purpose is: a kind of blower fan; Comprise blade and the wheel hub that is connected with blade; Blade installation wherein, also comprises a fluid drive mechanism and a synchronous generator on wheel hub; The input end of described fluid drive mechanism links to each other with the output terminal of said wheel hub, and the output terminal of fluid drive mechanism links to each other with described synchronous generator.
Above-mentioned blower fan; Wherein, Described fluid drive mechanism comprises that the oil hydraulic pump and of a closed loop is serially connected with the oil hydraulic motor on this oil hydraulic pump, and described oil hydraulic pump links to each other with the output terminal of wheel hub, and the output terminal of said oil hydraulic motor links to each other with described synchronous generator.
The invention has the beneficial effects as follows: the present invention adopts fluid drive mechanism to substitute original gear-box; Oil hydraulic motor is serially connected with on the oil hydraulic pump of closed loop, and oil hydraulic pump drives oil hydraulic motor, drives synchronous generator through oil hydraulic motor again; The synchronous generator generating is 50HZ; No longer inversion, directly online, the present invention has following three advantages:
1. in light weight, the application's quality and original comparing narrow down to original half thely, and the quality of whole blower fan has alleviated greatly, so ground device fabrication cost has also reduced greatly.
2. parts are few, saved these two big parts of gear-box and inverter among the application, and fluid drive mechanism is adopted in the centre, do not have the part of connecting shaft, do not have the part of hard connecting shaft, so parts are few, and reliability is high.
3. power generating quality is good, because adopted fluid drive mechanism, hydraulic pressure has the process of an energy storage, therefore; Even the wheel hub output terminal has fluctuation, because hydraulic pressure has flexibility, so fluctuation can reduce; The quality of synchronous generator generating can improve like this, and key is to have adopted oil hydraulic pump, after pump is exported oil; Oil flows through oil hydraulic motor, can let oil hydraulic motor produce rotating speed and drive synchronous generator, among the application; The speed of the input end of fluid drive mechanism changes, but output speed is invariable, and is effective.
Description of drawings
Fig. 1 blower fan structure schematic representation of the prior art;
Fig. 2 blower fan structure schematic representation of the present invention.
Embodiment
To combine accompanying drawing that the present invention is further specified below.
See also Fig. 2; A kind of blower fan of the present invention has been shown among the figure; Comprise blade 1 and the wheel hub 2 that is connected with blade 1, blade 1 is installed on the wheel hub 2, also comprises a fluid drive mechanism 3 and a synchronous generator 4; The input end of fluid drive mechanism 3 links to each other with the output terminal of wheel hub 2, and the output terminal of fluid drive mechanism 3 links to each other with synchronous generator 4.
Working principle: oil hydraulic pump 31 drives oil hydraulic motor 32, drives synchronous generator 4 through oil hydraulic motor 32 again, and synchronous generator 4 generatings are 50HZ, no longer inversion, directly online.The speed of the input end of fluid drive mechanism 3 changes among the present invention, but owing to adopted oil hydraulic pump 31, makes that its output is stable, invariable, therefore makes the operation that synchronous generator 4 also can be stable.
Above embodiment only supplies to explain the present invention's usefulness; But not limitation of the present invention; The technician in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification; Therefore all technological schemes that are equal to also should belong to category of the present invention, should be limited each claim.
Claims (2)
