Problems solved by technology

The prior art also has the following disadvantages: when the louver ventilation assembly needs a large amount of air exchange under extreme working conditions, the central area of ​​the polyester filter sponge towards the outside of the tower door does not receive sufficient support and at the same time receives the outward wind force. As a result, the adhesion between the polyester filter sponge and the screen press plate is reduced, which in turn affects the ventilation or filtration effect to a certain extent

Embodiment 1

[0031] like Figure 1 to Figure 7 As shown, a wind power tower door shutter ventilation device is arranged on the tower door 6, and two upper and lower sets of louver ventilation devices are arranged on the tower door 6. The louver ventilation device includes a louver frame body 1, and the front side of the louver frame body 1 is surrounded with a flange edge, through which the louver frame body 1 and the tower door 6 can be screwed. The rear side of the shutter frame body 1 is slidably provided with a protective net 2 , and the flange edge of the front outer edge of the shutter frame body 1 is fixed to the tower door 6 by bolt fasteners. The shutter frame body 1 includes a frame, a baffle plate and a shutter blade. The shutter frame body 1 is made of stainless steel and is suitable for outdoor use. The louver is fixed on the frame by welding. The protective net cover 2 includes an integrated protective net cover body 3 , a flexible filter layer 4 and a strength support laye...

Embodiment 2

[0038] A wind power tower door 6 shutter ventilation device, the difference between embodiment 2 and embodiment 1 is only: as Figure 8 As shown, the outer end of the protective net cover body 3 is provided with elastic ribs 8, and the elastic ribs 8 can be made of polymer materials such as rubber, which have high strength and toughness, and can be elastically deformed. The elastic rib 8 is provided with a connecting groove that matches the outer side of the protective net cover 3, the elastic rib 8 is provided with an outwardly convex expansion part 81 corresponding to the opening of the connecting groove, and the protective net cover 3 is provided with a corresponding connecting groove opening. Limit slot at the end. The elastic rib 8 covers the other three sides of the protective net cover body 3 except the side where the baffle 21 is located, including the opening side of the clamping groove of the protective net cover body 3, and has a protective effect. The elastic rib ...

Abstract

The invention discloses a wind power tower door shutter ventilation device which is arranged on a tower door, comprises a shutter frame body and is characterized in that a protective net cover is arranged on the rear side of the shutter frame body in a sliding mode, the protective net cover comprises a protective net cover body, a flexible filtering layer and a strength supporting layer which are integrally arranged, and a fixing mechanism is arranged between the protective net cover and the shutter frame body. The protective net cover has the advantages that the protective net cover integrates the flexible filter layer and the strength supporting layer, has certain strength, meanwhile, guarantees the filter capacity, and achieves structural enhancement of the protective net cover; the protective net cover is connected to the rear side of the shutter frame in a sliding mode and locked through the fixing mechanism after being in place in the shutter frame, the structure is reliable, mounting and dismounting are convenient, maintenance and replacement are convenient, and the replacement and maintenance efficiency of the ventilation device is improved.

Description

technical field [0001] The present application relates to the technical field of shutter ventilation devices, in particular to a wind power tower door shutter ventilation device. Background technique [0002] During the operation of the wind turbine, electrical equipment such as generators, converter cabinets and other electrical control cabinets will generate heat. In order to enable the wind turbine to operate normally, it is necessary to ventilate and dissipate these heat-generating components. At present, in addition to the axial flow fan installed on the tower (or tower), in order to ensure the ventilation volume, the louver installed on the tower door needs to be ventilated to assist heat dissipation, and the hot air in the tower is removed from the tower door. The louvers are exhausted to lower the ambient temperature inside the tower more quickly. [0003] The existing tower door shutter ventilation components are mainly composed of the shutter frame fixed on the to...
