Abstract

The utility model discloses a fan which comprises blades and hubs connected with the blades, as well as a hydraulic transmission mechanism and a synchronous power generator, wherein the blades are arranged on the hubs, an input end of the hydraulic transmission mechanism is connected with output ends of the hubs, and an output end of the hydraulic transmission mechanism is connected with the synchronous power generator. In the fan, the hydraulic transmission mechanism replaces the original gearbox, the power of the synchronous power generator is 50HZ without inversion; and the fan can be directly networked, and has the advantages of light weight, few parts, high reliability and good power generation quality.

Description

A kind of blower fan
Technical field
The utility model relates to a kind of blower fan, relates 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 ', by 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, the ground device fabrication cost height of blower fan.
2. parts are many because existing this structure need adopt gear-box 3 ' and inverter 5 ', these two parts all are big parts, are the easiest two parts that go wrong 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 purpose of this utility model is to overcome the defective of prior art and provides a kind of blower fan, 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 is on wheel hub, wherein, also comprise a fluid drive mechanism and a synchronous generator, the input end of described fluid drive mechanism links to each other with the output terminal of described 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 described oil hydraulic motor links to each other with described synchronous generator.
The beneficial effects of the utility model are: the utility model adopts fluid drive mechanism to substitute original gear-box, oil hydraulic motor is serially connected with on the oil hydraulic pump of closed loop, oil hydraulic pump drives oil hydraulic motor, drive synchronous generator by oil hydraulic motor again, the synchronous generator generating is 50HZ, no longer inversion, directly online the utlity model has following three advantages:
1. in light weight, the application's quality and original comparing narrow down to original half, 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, the reliability height.
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, and the synchronous generator quality of generating electricity can improve like this, key is to have adopted oil hydraulic pump, after pump was exported oil, oil flow through oil hydraulic motor, can allow 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.

Fig. 2 blower fan structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
See also Fig. 2, there is shown a kind of blower fan of the present utility model, comprise blade 1 and the wheel hub 2 that is connected with blade 1, blade 1 is installed on the wheel hub 2, also comprise 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.
Fluid drive mechanism 3 comprises that the oil hydraulic pump 31 and of a closed loop is serially connected with the oil hydraulic motor 32 on this oil hydraulic pump 31, and oil hydraulic pump 31 links to each other with the output terminal of wheel hub 2, and the output terminal of oil hydraulic motor 32 links to each other with synchronous generator 4.
Working principle: oil hydraulic pump 31 drives oil hydraulic motor 32, drives synchronous generator 4 by 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 in the utility model, 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 is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technological schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
