The fan tower tube radiation device has reasonable structure arrangement, and is simple to operate; the problem of radiation of a fan tower bottom is greatly eliminated, and the operation efficiency of a fan is improved; and the device can meet the requirement of the fan and a control cabinet on long-time normal operation, and has no need to change a structure of a fan tower tube.
Description
Technical field
The utility model relates to a kind of sink, and is particularly a kind of for the blower fan tower barrel sink under the land hot environment.
Background technique
Because the wind-powered electricity generation industry developed rapidly in recent years, it is relatively concentrated that wind energy resources enriches the area, and the high wind speed area has become rare resource at present.In the situation that the Wind Power Generation in the abundant area of wind resource has hastened towards saturation at present, the low wind speed and wind electric field exploitation that resource is owed abundant area will welcome the huge market space.Low wind speed wind field has two distinguishing features, and the one, wind speed is between the 6-8 meter per second, and annual utilization hours is below 2000 hours; The another one characteristics are that low wind speed wind field is positioned at the high a lot of area of the more northern high wind speed wind field of the temperature such as Anhui, Hubei, Fujian and Yunnan mostly.Summer temp raises, and can't effectively discharge because of the heat that control apparatus work at the bottom of the blower fan tower produces, and causes blower fan high temperature alarm often to occur, and serious cause blower fan off-grid and control apparatus burn, and cause serious consequence.
Usually the tower cylinder of Megawatt fan generally is comprised of cylindrical shell, electric and maintenance platform, cat ladder, access door etc., and control cabinet generally is installed on the electric platform in the tower cylinder first paragraph tower cylinder at the bottom of the blower fan tower.In the long-time fan operation process of process, the equipment such as control cabinet will produce a large amount of heats, and owing to tower barrel platform relatively seals, these heats are hoarded for a long time at the bottom of the blower fan tower, certainly will cause at the bottom of the tower air temperature to rise and can't discharge, cause the equipment high temperature alarm, reduce the operational efficiency of blower fan, economic loss.It is to offer a gas fan that is used for air-supply at tower cylinder access door that tradition solves the method for dispelling the heat at the bottom of the tower, and the air that tower is outer is introduced in the tower, lowers the temperature; This mode is installed simply, can play certain cooling-down effect, but along with variation, the especially development of wind-powered electricity generation machine set technology in wind energy turbine set geographical position, the uptime of blower fan constantly increases, thereby the normal operation of control cabinet is proposed requirements at the higher level; Traditional radiating solution can not solve the too high problem of column bottom temperature.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for existing heat dissipation technology, provides that a kind of structural design advantages of simple, dismounting are convenient, the blower fan tower barrel sink of Effective Raise fan operation efficient.
Technical problem to be solved in the utility model is to realize by following technological scheme.The utility model is a kind of blower fan tower barrel sink, be characterized in: this device comprises air-supply unit and the air draft unit that is fixed on the tower cylinder access door, air-supply unit and air draft unit all are connected with electric control box, temperature detect switch (TDS), by the keying of temperature detect switch (TDS) control air-supply unit and air draft unit, the air intake cylinder of air-supply unit, the exhaust tube of air draft unit all extend out to outside the tower cylinder access door.
In the blower fan tower barrel sink technological scheme described in the utility model: described air draft unit preferably is fixed on the top of tower cylinder access door, and the air-supply unit is preferably mounted at the bottom of tower cylinder access door.
In the blower fan tower barrel sink technological scheme described in the utility model: the setting that is inclined upwardly of the exhaust outlet of described exhaust tube, exhaust outlet and horizontal plane preferably are 65 °-85 °.
In the blower fan tower barrel sink technological scheme described in the utility model: described air intake cylinder preferably is and is horizontally disposed with, and the intake grill of air intake cylinder preferably down.
In the utility model, introduce the outer Cryogenic air of tower by the air-supply unit that arranges, be used for getting rid of the high temperature air of tower cylinder inside by the air draft unit is set, electric control box is for control air-supply unit and the work of air draft unit; Air-supply unit and air draft unit adopt temperature detect switch (TDS) control, when temperature in the tower cylinder is higher than setting temperature (such as 40 ℃), air draft unit and air-supply unit are opened, air-supply unit and air draft unit are in holding state when ambient temperature is equal to or less than set temperature in the tower cylinder, start and stop by temperature detect switch (TDS) control blower fan and then can effectively organize the heat exchange of air in the tower cylinder effectively prolong the working life of blower fan simultaneously.
Air draft unit of the present utility model and air-supply unit preferably are installed on the tower cylinder access door according to upper-lower position, to realize the stable operation of air draft unit and air-supply unit; According to the hot air rising characteristic, the air draft unit is installed in tower cylinder access door top, to realize that hot air is discharged from a large number; Going out several mouthfuls and being inclined upwardly of the exhaust tube of air draft unit can prevent that the heat of rainwater inlet and outlet from entering the air-supply unit.The unit of will blowing is installed in tower cylinder access door bottom, to realize that cool air is introduced in the tower in a large number control cabinet is directly lowered the temperature; The intake grill of the turnover cylinder of air-supply unit arranges down, can prevent that rainwater introducing tower is interior and avoid introducing the hot air that the air draft unit is sent.
Electric control box can be installed on the suitable position of the electric platform of tower cylinder, the temp probe of temperature detect switch (TDS) is placed on the temperature province that needs control and fixes, and the power switch of the controller that closes is made as desired temperature the value that needs; By closure give, the automatic power supply switch of air bells exhauster, start simultaneously air draft unit, air-supply unit, to realize the heat radiation purpose.
Compared with prior art, the utility model blower fan tower barrel construction for heat radiating device arranges rationally, and is simple to operate, eliminated greatly heat dissipation problem at the bottom of the blower fan tower, improved the operational efficiency of blower fan.This device had both satisfied also blower fan and the long-time normal operation of control cabinet, did not need again blower fan tower barrel is carried out structural change.
