Abstract
The invention discloses a heat radiation and ventilation device of a mechanical brake of a wind generating unit. The heat radiation and ventilation device comprises a fan and a heat stream guidance protection cover; the fan is mounted on the heat stream guidance protection cover; the heat stream guidance protection cover is mounted on the end face of a gearbox of the wind generating unit; and a braking valve and a braking disk of the wind generating unit are arranged in the heat stream guidance protection cover. The heat radiation and ventilation device provided by the invention can be forced to reduce the temperature of the surface of the braking disk of the wind generating unit through ventilation and heat radiation, and can prevent spark generated by the brake from splashing simultaneously, so that the fire accident caused by the mechanical brake can be avoided.
Description
Technical field
The invention belongs to technical field of wind power generator, particularly relate to a kind of wind power generating set mechanical brake radiation ventilator.
Background technique
Wind energy is a kind of safe and reliable green energy resource, also is that a kind of energy density is low, the energy of poor stability.Different wind-driven generators has certain area requirement to wind speed.In the wind-driven generator normal course of operation, when being higher or lower than scope of design, wind speed needs the emergency shutdown braking.When wind-driven generator breaks down the needs maintenance, also need to shut down.
The mechanical braking device of wind-driven generator is installed on the speedup box output shaft usually at present, the speedup box output shaft is connected with generator by elastic coupling flexible coupling, be integrated with the brake puck of mechanical braking device on the elastic coupling flexible coupling, the brake correspondence is installed in the speedup box end face.When wind power generating set was carried out mechanical brake, brake and brake puck friction can produce amount of heat and spark, and the brake puck surface temperature can surpass 700 ℃ rapidly, and near the lubricated wet goods flammable material very easily igniting causes higher fire risk.
Summary of the invention
Purpose of the present invention just provides a kind of wind power generating set mechanical brake radiation ventilator, can effectively prevent the fire accident of mechanical brake initiation, can solve the problem of above-mentioned prior art fully.
Purpose of the present invention realizes by following technical proposals:
A kind of wind power generating set mechanical brake radiation ventilator, comprise fan and thermally induced flow guard shield, fan is installed on the thermally induced flow guard shield, and this thermally induced flow guard shield is installed in the speedup box end face of wind power generating set, and the brake of wind power generating set and brake puck place the thermally induced flow guard shield.
Further, offer intake grill and thermovent on the described thermally induced flow guard shield, at intake grill place provided with fan.
Compared with prior art, beneficial effect of the present invention is: simple in structure, convenient for installation and maintenance, reasonable in design, can the forced ventilation heat radiation reduce the brake puck surface temperature, the spark that produces that prevents from simultaneously braking splashes, thereby avoids the fire accident because of the mechanical brake initiation.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the structural representation of the embodiment of the invention two.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Embodiment one
As shown in Figure 1, a kind of wind power generating set mechanical brake radiation ventilator comprises fan 2 and thermally induced flow guard shield 4, offers intake grill and thermovent on the thermally induced flow guard shield 4, at intake grill place provided with fan 2.
In use, thermally induced flow guard shield 4 is installed in speedup box 5 end faces of wind power generating set, make brake 3 and brake puck 1 place thermally induced flow guard shield 4, be installed in elastic coupling flexible coupling 6 on speedup box 5 output shafts and pass thermally induced flow guard shield 4 and be connected with generator 7, the fan 2 on the thermally induced flow guard shield 4 is corresponding with brake puck 1 position.
Start the fan work instruction when wind power generating set is sent the brake instruction, fan 2 rotates lowers the temperature to brake puck 1 surface, and extraneous colder air blows to brake puck 1 surface by fan 2, and the hot air in the thermally induced flow guard shield 4 is discharged by thermovent.Because brake 3 and brake puck 1 are covered by thermally induced flow guard shield 4, so brake 3 and brake puck 1 fricative spark, have been blocked in the thermally induced flow guard shield 4, can not splash away, thereby avoid the fire accident that causes because of mechanical brake.
Described fan 2 directly is connected with blower fan master control set 9 by 9 controls of blower fan master control set.
Embodiment two
As shown in Figure 2, present embodiment is that with the difference of implementing one described fan 2 also can be connected with the fire-fighting control gear 8 of wind power generating set, and fire-fighting control gear 8 is connected with blower fan master control set 9, and fan 2 is by 8 controls of fire-fighting control gear.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. wind power generating set mechanical brake radiation ventilator, it is characterized in that: comprise fan and thermally induced flow guard shield, fan is installed on the thermally induced flow guard shield, this thermally induced flow guard shield is installed in the speedup box end face of wind power generating set, and the brake of wind power generating set and brake puck place the thermally induced flow guard shield.
2. wind power generating set mechanical brake radiation ventilator according to claim 1 is characterized in that: offer intake grill and thermovent on the described thermally induced flow guard shield, at intake grill place provided with fan.
