Abstract
The invention relates to a cabin top cover of a wind-driven generator, which comprises a top cover and a supporting frame. The top cover is arranged on the supporting frame which is fixed on a cabin and provided with more than two sleeves in radial positions; the interior of each sleeve is in a circular step shape; a guide rod is mounted in each sleeve and sleeved by a spring; the bottom end of the spring is fixed on the guide rod; the upper part of the spring is embedded on the circular step of the sleeve; the upper part of the guide rod is fixed on the top cover by a locking nut; the supporting frame is internally provided with a horizontal separator; a hydraulic cylinder is fixed in the center of the upper surface of the horizontal separator; a hydraulic cylinder cover is fixed on the upper surface of the hydraulic cylinder which is internally provided with a piston rod penetrating through the hydraulic cylinder cover; and the bottom of the hydraulic cylinder is provided with an oil inlet. The cabin top cover is automatically opened to ensure hot air in a blower to be expelled into atmosphere while the blower normally generates electricity, and is automatically closed when the blower stops generating electricity so as to prevent rainwater and corrosive gases, such as smoke, and the like from entering the blower.
Description
Technical field
The present invention relates to a kind of cabin top cover of wind-driven generator.
Background technique
The cooling of blower fan is most important to the normal operation of whole blower fan system, and the cooling problem is troubling each blower fan MANUFACTURER always.At present, a lot of blower fans all exist because cabin and wheel hub inside temperature are too high, cause the phenomenon of other parts cisco unity malfunction to happen occasionally, and for example, become the oar motor and often cause reporting to the police owing to temperature is too high, even the shutdown of breaking down.
In order to solve the cooling problem of blower fan, common way is at the inner blower of installing of blower fan, utilizes blower that generator set is cooled off, and puts in a skylight in nacelle top, realizes the exchange of the inside and outside heat of blower fan, reaches the purpose of cooling blower.
But also there is defective in the method that puts in a skylight in nacelle top, and when blower fan is not worked (for example during the typhoon), the skylight remains opens, if run into rainyly, rainwater will enter blower fan from the skylight, the electrical equipment of fragile blower fan inside.
Summary of the invention
The objective of the invention is in order to overcome the above-mentioned defective that prior art exists, provide a kind of can be according to the cabin top cover of wind-driven generator of opening and closing of the working state robot brain cabin top cover of blower fan.
Technological scheme of the present invention is: it comprises top cover, also be provided with supporting frame, described top cover is located on the supporting frame, supporting frame is fixed on the cabin, be provided with plural sleeve in the radial position of supporting frame upper edge, sleeve inner is an annular stepped shape, and guide rod is installed in the sleeve, is with spring on the guide rod, the spring bottom is fixed on the guide rod, the top of spring is embedded in the circular step place of sleeve, and guide rod top is fixed on the top cover by tightening nut, is provided with horizontal baffle in the supporting frame, horizontal baffle upper surface central position is fixed with oil hydraulic cylinder, the oil hydraulic cylinder upper surface is fixed with hydraulic cylinder, is provided with the piston rod that passes hydraulic cylinder in the oil hydraulic cylinder, and the oil hydraulic cylinder bottom has filler opening.
Described top cover central upper portion position is processed with the top cover boss.
The present invention is when the blower fan normal power generation, and cabin top cover is opened automatically, can guarantee that the hot air in the blower fan can be discharged in the atmosphere, and when the blower fan generation outage, top cover can be closed automatically, thereby can prevent that corrosive gass such as rainwater and salt fog from entering blower fan inside.
Description of drawings
Fig. 1 is the structural representation after one embodiment of the invention and the cabin assembling.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to accompanying drawing, present embodiment comprises top cover 1, also be provided with supporting frame 6, described top cover 1 is located on the supporting frame 6, supporting frame 6 is fixed on the cabin 15 by bolt 13, be provided with 2 sleeves 5 in supporting frame 6 upper edge radial positions, sleeve 5 inside are annular stepped shape, guide rod 2 is installed in the sleeve 5, be with spring 3 on the guide rod 2, spring 3 bottoms are fixed on the guide rod 2, and the top of spring 3 is embedded in the circular step place of sleeve 5, guide rod 2 tops are fixed on the top cover 1 by tightening nut 12, be provided with horizontal baffle 14 in the supporting frame 6, horizontal baffle 14 upper surface central positions are fixed with oil hydraulic cylinder 7 by standing screw 4, and oil hydraulic cylinder 7 upper surfaces have hydraulic cylinder 9 by bolt, be provided with the piston rod 8 that passes hydraulic cylinder 9 in the oil hydraulic cylinder 7, oil hydraulic cylinder 7 bottoms have filler opening 11.
Described top cover 1 central upper portion position is processed with top cover boss 10.
During the blower fan normal power generation, from the driftage hydraulic braking sytem, draw one road hydraulic oil and inject oil hydraulic cylinder 7 by filler opening 11, the driftage hydraulic braking sytem provides lasting hydraulic oil for oil hydraulic cylinder 7, produce bigger malleation in the blower fan, under pressure, piston rod 8 passes through top cover boss 10 with top cover 1 jack-up, the blower that is installed in the blower fan is discharged to the external world with hot air by the top cover of opening 1, top cover 1 is during by jack-up, top cover 1 drives guide rod 2 and moves upward, spring 3 is compressed, and spring 3 produces certain spring-back force; When the blower fan generation outage, the driftage hydraulic braking sytem stops to provide hydraulic oil to oil hydraulic cylinder 7, decompression in the oil hydraulic cylinder 7, and top cover 1 is closed under the tension of spring 3 automatically.
When the blower fan normal power generation, maintain bigger malleation in the blower fan, not only rainwater can not enter in the blower fan, and because the driftage hydraulic braking sytem provides lasting hydraulic oil for blower fan, thereby can guarantee that top cover 1 opens all the time when the blower fan normal power generation; When the blower fan generation outage, top cover 1 is closed under the effect of spring 3 pulling force automatically, can prevent effectively that corrosive gass such as rainwater and salt fog from entering blower fan inside.
