Background

With the continuous development of technology and the increasing demand for ocean development, more and more countries use mobile offshore platforms to carry out long-term ocean-going research and exploration. Because the offshore platform is in an island operation state for a long time, the supplement of energy is the most key core problem. A small-capacity offshore suspended tidal current energy generator is equipped for a mobile offshore platform to serve as a platform standby power storage source, so that a mainstream mobile offshore platform energy source supplementing mode is formed. The general tidal current energy generator realizes the internal cooling of the generator set by using a built-in electric fan, and the internal space cannot meet the requirement of the fan due to the small size of the small-capacity offshore suspended tidal current energy generator; meanwhile, as a standby power storage power supply of the mobile offshore platform, the generating capacity of the unit is small, if a fan is arranged to cool the inside of the generator, the fan needs to consume extra electric energy, so that the generating efficiency of the generator is greatly reduced, and the design purpose cannot be achieved. Therefore, a fan type cooling device of the marine suspended tidal current energy generator, which does not consume extra electric energy, occupies a small space and has a stable operation effect, is urgently needed to meet the use requirement of the small-capacity marine suspended tidal current energy generator.

The technical scheme of the utility model is that: the rotating fan is characterized in that the rotating fan body, the locking bolt and the stop washer form a whole, the rotating fan body is sleeved on the end head of the rotating shaft of the generator from left to right, then the locking bolt sequentially penetrates through holes in the stop washer and the rotating fan body and is screwed into a threaded hole in the top end of the end head of the rotating shaft of the generator, and the locking bolt is tightened to form a whole to complete installation.

The rotating fan main part be centrifugal air current control principle, by being to the deep bead, the upright rib, forward deep bead, the central body is constituteed wholly, place the central body level, use 8 upright ribs to use the central body to be the centripetally equipartition of the vertical circumference of centre of a circle, the play wind side of upright rib is the same with the recess direction of central body, evenly weld the upright rib on the outer circle of central body, then will be put into to the deep bead from the air inlet side of upright rib, it is concentric to deep bead and central body, by welding firmly the back perpendicularly to deep bead and upright rib, put into the fan-shaped space that forms between per two upright ribs from the play wind side of upright rib again with 8 forward deep beads, and weld firmly perpendicularly with the upright rib, form wholly.

The central body is in a hollow cylinder shape, a groove matched with the end head of the rotating shaft of the generator is arranged in the central body, and the groove is in small clearance fit with the end head of the rotating shaft of the generator.

The main body of the rotating fan is in close clearance fit with the wind shield after being installed.

Technical effects

For traditional fan structure, the utility model has the characteristics of it is following:

1. the utility model discloses simple structure, occupation space is little, and traditional fan heat dissipation design needs set up a plurality of parts such as fan, power, dc-to-ac converter simultaneously, needs very big space just can realize, the utility model discloses occupation space is little, provides under the condition of equal amount of wind, can practice thrift 70% space.

2. The utility model discloses need not to consume the electric energy, the rotating fan main part is synchronous rotatory along with the rotation of generator shaft, and the surplus rotatory kinetic energy of direct conversion generator shaft is for cooling the wind energy, and simultaneously, the rotating fan main part is centrifugal wind pressure principle, during the rotation, inhales the air from the air inlet side, then throws away the air from the air-out side, forms centrifugal wind pressure, decides, the straight blow of rotor core department to the generator, and the cooling effect is more obvious.

3. The utility model discloses an amount of wind can be adjusted along with the change of trend ability generator output, need not additionally to set up variable speed and wind volume detection mechanism, and when trend ability generator output was high, the generator temperature was higher, and the cooling amount of wind that needs is big, and the generator pivot rotational speed is fast this moment, the utility model provides a cooling amount of wind increases along with the pivot rotational speed accelerates; when trend can generator output is low, the generator temperature is lower, and the cooling amount of wind that needs is little, and the generator revolving shaft speed of this moment reduces, the utility model provides an amount of wind also reduces along with the revolving shaft speed of rotation and diminishes to reach the amount of wind and according to the purpose of generator power change and real-time adjustment.
