Abstract
The utility model relates to a tower for a wind generating set. A tower door is provided with more than one open hole, shutters are installed on the open hole portions of the tower door, an open hole is formed in the tower wall on the bottom of the tower, an axial flow fan is installed in the open hole of the tower wall, and a self-dropping type shutter is installed outside the open hole of the tower wall. According to the tower, hot air of the bottom of the tower can be effectively carried out from the tower, so that heat dissipation of the bottom of the tower is achieved. In addition, the tower is simple in structure and convenient to install.
Description
Technical field
The utility model relates to wind power generating set assembling field, particularly relates to a kind of tower cylinder of wind power generating set.
Background technique
In recent years, under the vigorously supporting of national policy, 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, the types such as naval counterpart, high-power type (3MW, 5MW), plateau type, ultralow temperature and export-oriented (60Hz) have in succession been there is, to adapt to different external environments and the market demand.
Yet the heat that in fan operation process, electric elements inside distributes normally moves and has formed stern challenge blower fan., while especially arriving high temperature season, ambient temperature is higher, and the heat that blower fan electric elements inside distributes can not be discharged tower cylinder in time, makes to cause blower fan normally not move, and even causes fan parking, has had a strong impact on utilization ratio and the generating efficiency of blower fan.
Frequency conversion tank high temperature alarm machine halt trouble becomes high temperature season and affects one of major failure of equipment at the bottom of the tower of the normal operation of blower fan.The main cause that fault forms has 3 points: 1, tower cylinder is relatively airtight, and in tower cylinder, air can not Efficient Cycle.2, the connecting passage of tower cylinder inner air and ambient air outside only has the venetian blind on tower cylinder door.3, the heat that in tower cylinder, electrical equipment produces during fan operation can not be discharged outside tower cylinder in time, and tower cylinder outer air can not enter tower cylinder in time, and air in tower cylinder is effectively supplemented.
As can be seen here, the tower cylinder of above-mentioned existing a kind of wind power generating set, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.How to found and a kind ofly can in time heat at the bottom of tower be taken, be installed out of the tower cylinder of simple, easy to operate new wind power generating set, 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 a kind of tower cylinder of wind power generating set, can in time heat at the bottom of tower be taken out of, be installed simple, easy to operate, thereby overcome the too high deficiency that causes equipment failure of existing blower fan column bottom temperature.
For solving the problems of the technologies described above, the utility model provides a kind of tower cylinder of wind power generating set, tower cylinder door is provided with an above perforate, and at the tapping of tower cylinder door, venetian blind is installed, on tower barrel at the bottom of tower, be also provided with perforate, and at the inside of tower tube wall opening installation shaft flow fan, in the outside of tower tube wall opening, self hang down type venetian blind is installed.
As a kind of improvement of the present utility model, the utility model also can be realized by following proposal:
A tower cylinder for wind power generating set, wherein, the perforate of described tower barrel is welded with reinforcing flange, and described axial-flow blower and self hang down type venetian blind are all arranged on tower barrel by this reinforcing flange.
A tower cylinder for wind power generating set, wherein, described reinforcing flange is oval or circular.
A tower cylinder for wind power generating set, wherein, the perforate on described tower cylinder door is two.
A tower cylinder for wind power generating set, wherein, the cross section that the perforate on described tower cylinder door is crossed central point along tower cylinder door is symmetrical.
A tower cylinder for wind power generating set, wherein, described venetian blind is provided with filter screen.
A tower cylinder for wind power generating set, wherein, on described tower cylinder door, perforate is square.
Adopt after such design, the utility model at least has the following advantages:
1, implement simply, easy for installation.
2, can effectively make tower cylinder inner air and outer air circulate.
3, can effectively reduce or eliminate the electrical equipment malfunction causing due to too high temperature of air at the bottom of tower.
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 tower cylinder tower bottom structure schematic diagram of a kind of wind power generating set of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Shown in Fig. 1, Fig. 2, the utility model provides a kind of tower cylinder of wind power generating set, tower cylinder door 1 is provided with an above perforate, and at the tapping of tower cylinder door 1, venetian blind 2 is installed, on tower barrel at the bottom of tower, be also provided with perforate, and at the inside of tower tube wall opening installation shaft flow fan 4, in the outside of tower tube wall opening, self hang down type venetian blind 5 is installed.
The tapping of tower barrel is welded with reinforcing flange 3, and axial-flow blower 4 is bolted on reinforcing flange 3, and is arranged on the inner side of tower cylinder, and self hang down type venetian blind 5 is connected with reinforcing flange 3 by bolt, and is arranged on the outside of tower cylinder.
Perforate on tower cylinder door 1 is preferably two, and the cross section that the perforate on tower cylinder door 1 is crossed central point along tower cylinder door 1 is symmetrical.On venetian blind 2, be provided with filter screen, can be arranged on by bolt the tapping of tower cylinder door 1.Preferably, on tower cylinder door 1, perforate is square; Reinforcing flange 3 is oval or circular.
When axial-flow blower 4 rotates, the hot air of tower cylinder inside can be blown to tower cylinder outside, now, self hang down type venetian blind 5 is opened, and the hot air in tower cylinder is discharged to outside tower cylinder; Because self hang down type venetian blind 5 is one direction ventilation, make the certain negative pressure of formation in tower cylinder, outside tower cylinder the suction function of air in tower cylinder under by two venetian blinds 2 on tower cylinder door 1, enter in tower cylinder, thereby guarantee that tower cylinder inner air and outside air can form Efficient Cycle.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
