Background

At present, the corner guide vanes of domestic high-low temperature annular wind tunnels generally adopt a built-in support design, the principle of the built-in support design is that the corner guide vanes take a bottom plate and a top plate of a reinforced concrete air duct as stress support points, and the stress of the corner guide vanes is finally transmitted to the bottom plate and the top plate of the reinforced concrete air duct.

Chinese patent 202011573484.0 discloses an anti-icing and drainage device for the corner of an icing wind tunnel, wherein the corner deflector of the wind tunnel is directly fixed between the top plate and the bottom plate of the wind tunnel, and the built-in support design can finally transfer the stress of the corner deflector to the top plate and the bottom plate of the wind tunnel, so that the wind tunnel generates fatigue stress and deformation to affect the service life of the wind tunnel.

Disclosure of Invention

The invention aims to provide an external mounting structure of a wind tunnel corner flow deflector, which aims to solve the technical problem that the flow deflector has adverse effect on a reinforced concrete wind channel.

In order to achieve the purpose, the specific technical scheme of the invention is as follows:

an external mounting structure of wind tunnel corner guide vanes comprises a wind tunnel, wind tunnel side wall reinforcing columns arranged on two sides of the wind tunnel and a plurality of corner guide vanes arranged in the wind tunnel, wherein the upper end of the wind tunnel is a wind tunnel top plate, and the lower end of the wind tunnel is a wind tunnel bottom plate; the top end of the air duct side wall reinforcing column is provided with a truss, and the bottom end of the air duct side wall reinforcing column is provided with a raft foundation; the corner flow deflectors are arranged between the truss and the raft foundation through a supporting structure;

the supporting structure comprises a first base arranged at the upper end of the corner flow deflector and a second base arranged at the lower end of the corner flow deflector, the upper end of the first base is fixedly connected with a plurality of first connecting pieces, and the first connecting pieces penetrate through reserved holes of the air duct top plate and are fixedly connected with the truss; the lower end of the second base is fixedly connected with a plurality of second connecting pieces, and the second connecting pieces penetrate through reserved holes of the air duct bottom plate and are fixedly connected with the raft foundation;

the first base and the second base block the reserved hole.

Therefore, the corner guide vanes are arranged between the first base and the second base, and the stress of the corner guide vanes is transmitted to the truss and the raft foundation through the connecting pieces, so that the structure does not take the main structure of the air duct platform as a bearing member any more, and the adverse effect of the corner guide vanes on the reinforced concrete air duct is reduced; the reserved hole is blocked by the first base and the second base, and airflow is prevented from entering the outer layer of the air duct from the hole.

Furthermore, raft foundation upper end sets up a plurality of fixed orificess, the bottom of second connecting piece inserts in the fixed orifices links to each other with it is fixed.

And furthermore, an embedded part is reserved at the top of the air duct side wall reinforcing column, and the truss is connected with the air duct side wall reinforcing column through the embedded part.

Furthermore, the thickness of the raft foundation is 600-800 mm, and preferably the thickness of the raft foundation is 600 mm.

The invention has the following advantages: compared with the traditional built-in supporting design of the corner guide vanes, the built-in supporting design of the corner guide vanes is changed into the external supporting design, the main structure of the air duct platform is not used as a bearing member, the adverse effect of the corner guide vanes on the air duct platform is effectively reduced, the structural deformation of the air duct platform is prevented, the experimental effect is ensured, and the service life is prolonged.
