The model utility content
Leak out everywhere in order to solve unit, the sand and dust in the atmosphere enter engine room inside, influence the problem of the normal operation of unit, the purpose of this utility model is to provide a kind of wind generating set engine room seal arrangement; The sealing device is separately positioned between blade and the air guide sleeve, between air guide sleeve and the engine room cover and between engine room cover and the tower tube.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises adhesive tape and pressing plate, and wherein adhesive tape is arranged on the joint of two links, installs and fixes by pressing plate, and described adhesive tape and two links are tightly connected respectively.
Wherein: described adhesive tape is a ring, is located on first link, and described pressing plate is stacked in the top of this adhesive tape, by bolt adhesive tape is fixed on first link; The interior ring surface of described adhesive tape is set on second link and with second link and seals butt; Have the hole that penetrates for second link on first link, the aperture in this hole is between the inner and outer rings diameter of described adhesive tape; Pressing plate is a plurality of, is distributed on the adhesive tape; Pressing plate is whole ring, and its outer ring diameter is identical with the outer ring diameter of adhesive tape, and the interior ring diameter of pressing plate is greater than the interior ring diameter of adhesive tape; Described seal arrangement is arranged between blade and the air guide sleeve respectively, between engine room cover and the air guide sleeve and between tower tube and the engine room cover.
Advantage of the present utility model and good effect are:
1. the utility model has adopted adhesive tape sealing, can stop sand and dust to enter the cabin effectively, has guaranteed the normal operation of unit; Simultaneously, seal arrangement of the present utility model can also guarantee that the hot air in the cabin in winter can not leak in a large number, keeps the temperature in the cabin.
2. the utility model both can guarantee sealing effect between blade and the air guide sleeve, between air guide sleeve and the engine room cover and all adopt adhesive tape sealing between engine room cover and the tower tube, did not influence again to relatively rotate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 is blade, and 2 is air guide sleeve, and 3 is engine room cover, and 4 is the tower tube, and 5 is adhesive tape, and 6 is pressing plate.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model comprises adhesive tape 5 and pressing plate 6, and wherein adhesive tape 5 is arranged on the joint of two links, installs and fixes by pressing plate 6, and described adhesive tape 5 is a ring, is tightly connected respectively with two links.
As shown in Figure 1, the cabin of wind power generating set protection is made up of interconnective air guide sleeve 2 and engine room cover 3, and blade 1 passes air guide sleeve 2, is installed on the main frame in the cabin, and tower tube 4 passes engine room cover 3 and is connected with main frame in the cabin.Seal arrangement of the present utility model is arranged between blade 1 and the air guide sleeve 2 respectively, between engine room cover 3 and the air guide sleeve 2 and between tower tube 4 and the engine room cover 3.
The joint of blade 1 and air guide sleeve 2, air guide sleeve 2 raises up, and is used to install the adhesive tape 5 of sealing; Have the hole on the described projection, blade 1 penetrates air guide sleeve 2 by this hole.The adhesive tape 5 of ring is placed on the air guide sleeve 2, and the external diameter of the high spot on the outer ring diameter of adhesive tape 5 and the air guide sleeve 2 is identical.The interior ring surface of adhesive tape 5 and blade 1 sealing butt, pressing plate 6 is stacked in the top of adhesive tape 5, by bolt adhesive tape 5 is fixed on the air guide sleeve 2.The diameter that air guide sleeve 2 projectioies go up the hole makes that adhesive tape 5 can be with the clearance seal between blade 1 and the air guide sleeve 2 between the inner and outer rings diameter of adhesive tape 5.
The joint of air guide sleeve 2 and engine room cover 3, the bottom surface of air guide sleeve 2 has the hole, and engine room cover 3 is the seam shape with the connecting end of air guide sleeve 2, and this stop portion is plugged on the air guide sleeve 2 by the hole.The adhesive tape 5 of ring is placed on the air guide sleeve 2, and the outer ring diameter of adhesive tape 5 can be slightly less than the bottom surface external diameter of air guide sleeve 2 or identical with the bottom surface external diameter of air guide sleeve 2.The interior ring surface of adhesive tape 5 and the seam end of engine room cover 3 sealing butt, pressing plate 6 is stacked in the outside of adhesive tape 5, by bolt adhesive tape 5 is fixed on the air guide sleeve 2.The aperture in the hole that air guide sleeve 2 bottom surfaces are offered makes that adhesive tape 5 can be with the clearance seal between engine room cover 3 and the air guide sleeve 2 between the inner and outer rings diameter of adhesive tape 5.
