The wind generating set tower bottom heat dissipating device can be widely applied to tower bottom heat dissipation of wind generating sets of various types, mounting is easy, and transformation is convenient.

Description

Sink at the bottom of a kind of wind power generating set tower
Technical field
The utility model relates to wind-driven generator pack heat dissipation device field, particularly relates to sink at the bottom of a kind of wind power generating set tower.
Background technique
In recent years, under the support energetically of national policy, green energy resource develops rapidly, especially wind-power electricity generation industry development, China has become the fastest wind-power electricity generation market of global evolution, the type of wind-driven generator also by original single type to development in pluralism, in succession there is the types such as naval counterpart, high-power type (3MW, 5MW), plateau type, ultralow temperature and export-oriented (60Hz), to adapt to different external environments and the market demand.
The external environment of various complexity is normally moved and has been formed stern challenge wind-powered electricity generation unit, and at the bottom of tower, frequency variator is as the interface of wind-powered electricity generation unit and electrical network, and the height of its working efficiency can affect Generation Rate and the utilization ratio of wind power generating set.The external condition that affects frequency variator working efficiency is mainly the air temperature at the bottom of tower, and the too high temperature of air at the bottom of tower, in the time of can not meeting the demand of frequency variator, will cause the reduction of wind power generating set Generation Rate, even shuts down.
The factor of air temperature at the bottom of tower that affects mainly contains following three kinds of situations: 1, the size of tower base space.Tower base space is larger, and at the bottom of tower, air temperature rising is slower, otherwise, very fast.2, the type of cooling of frequency variator at the bottom of tower, the main flow type of cooling of frequency variator is air-cooled at present, this just requires air at the bottom of tower to form circulation with ambient air, or effectively supplements at the bottom of having air outside tower to tower, to there is the air supply frequency variator of suitable temperature to carry out cooling.3, summer environment temperature in some areas is higher; and equipment is in a relatively airtight environment at the bottom of tower; cause temperature at the bottom of tower higher than or surpass the normal working temperature of frequency variator; thereby very easily cause wind power generating set Generation Rate to decline, What is more causes wind power generating set shutdown not move.
How to found sink at the bottom of a kind of good heat dissipation effect, new wind power generating set tower easy for installation, real one of the current important research and development problem that belongs to.
Model utility content
The technical problems to be solved in the utility model is to provide sink at the bottom of a kind of wind power generating set tower, makes it take away in time heat, easy for installation at the bottom of tower, thereby overcomes the too high deficiency that affects generating efficiency of existing blower fan column bottom temperature.
For solving the problems of the technologies described above, the utility model provides sink at the bottom of a kind of wind power generating set tower, comprise the axial-flow blower being arranged on tower barrel platform, be arranged on the tower barrel platform below air intake pipe corresponding with described axial-flow blower intake grill, be arranged on tower barrel platform top wind pipe and the axial-flow blower that be above fixed on tower cylinder door inner side corresponding with described axial-flow blower exhaust outlet.
As a kind of improvement, described air intake pipe intake grill and tower cylinder door lay respectively at the both sides of the equipment that needs heat radiation.
Two axial-flow blowers are installed in described tower cylinder door inner side.
Described tower cylinder outer side of door is being provided with venetian blind with axial-flow blower corresponding part.
Described venetian blind is built-in with filter screen.
Described wind pipe by guide duct support and tower cylinder in cat ladder fix.
Adopt after such design, the utility model at least has the following advantages:
1, the utility model becomes initiatively air intake by the passive air intake of tower cylinder bottom, and passive the rising to initiatively of hot air that changes tower cylinder bottom risen, and effectively reduces the temperature of tower cylinder bottom air.
2, the utility model can be widely used in dispelling the heat at the bottom of various types of wind power generating set towers, is easy to install, conveniently transform.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the structural representation of sink at the bottom of a kind of wind power generating set tower of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is wind pipe assembling schematic diagram of the present utility model.
Fig. 4 is tower cylinder door assembling schematic diagram of the present utility model.
Embodiment
Shown in Fig. 1-4, the utility model provides sink at the bottom of a kind of tower of wind power generating set, comprise the axial-flow blower 4 being arranged on tower barrel platform 7, be arranged on the tower barrel platform 7 belows air intake pipe 3 corresponding with described axial-flow blower 4 intake grills, be arranged on tower barrel platform 7 tops wind pipe 5 and the axial-flow blower 2 that be above fixed on tower cylinder door 6 inner sides corresponding with described axial-flow blower 4 exhaust outlets.
Preferably, the outside of tower cylinder door 6 is provided with venetian blind 1, and corresponding with the axial-flow blower 2 of tower cylinder door 6 inner sides, axial-flow blower 2 and venetian blind 1 are preferably two groups.The built-in filter screen of venetian blind 1, venetian blind 1 flange mounting hole is corresponding with axial-flow blower 2 flange mounting holes, by bolt, venetian blind 1 and axial-flow blower 2 and tower cylinder door 6 is fixed together.
Air intake pipe 3 is connected with the lower flange of axial-flow blower 4, and wind pipe 5 is connected with the upper flange of axial-flow blower 4.Air intake pipe 3 and axial-flow blower 4 are connected with tower barrel platform 7 by bolt, and wind pipe 5 supports 8 by suspension ring and guide duct and is connected, and guide duct supports 8 and is bolted in a side of cat ladder 9 in tower cylinder.
