Abstract
The invention discloses a sealing structure for an independent support and a pressure bearing shell in a wind tunnel. The structure comprises a test section platform (1) of the independent support; the test section platform (1) is supported by upright posts (4) which pass through a shell (3) of a wind tunnel plenum chamber (2); the bottom of each upright post (4) has contact with the ground; a section of vertical pipeline (5) is welded on the edge of a hole in a position where each upright post (4) passes through the shell (3) of the wind tunnel plenum chamber (2); the bottom of the pipeline (5) is connected with the upper end of a self-balancing expansion joint (6) through a flange; and the lower end of the self-balancing expansion joint (6) is connected with the sidewalls of the upright posts (4) through the flanges. The sealing structure disclosed by the invention aims to solve the problem of sealing between the independent support and the shell of the wind tunnel and can isolate force transmission between the independent support and the shell so as to prevent gravity load from being transmitted to the shell of the plenum chamber in a test section.
Description
Technical field
The present invention is a kind of sealing structure supporting for the independence in wind-tunnel and pressure-bearing shell between, belongs to Aeronautical Wind Tunnel
Testing equipment.
Background technology
During large continuous transonic wind tunnel, nozzle section, test section and two venturi sections are placed in chamber interior,
Wind-tunnel axially, is connected with the wall of load in room by bolt, and axial force transmission is given in room.In gravity direction, due to nozzle section, examination
Test section and two venturi section gravity are heavier (gross weight is in 1000t), directly gravitational load is applied in room housing, will become in room
Shape and destroy, so needing to support nozzle section, test section and two venturi section free-standing structure to pass in room, be directly installed on
On civil engineering pre-embedded steel slab.
Bear malleation and negative pressure in room housing, accordingly, it would be desirable to independent support and stay setting between room can bear malleation and
The sealing structure of negative pressure, this sealing structure not only to isolate in room and independent support between power, also to easily keep in repair simultaneously and
Change.
Some construction of wind tunnels are directly to be placed in chamber interior by sections such as test sections at present, now need housing is carried out
Strengthen, simultaneously as vibration during test section test, also by conduct vibrations to housing upper face.And adopt the wind-tunnel of sealing structure also
It is not publicly reported.
Content of the invention
The present invention is exactly directed to shortcoming present in above-mentioned existing construction of wind tunnel and designs and provide a kind of being used in wind-tunnel
Independence support and pressure-bearing shell between sealing structure, its objective is solve wind-tunnel independently support the sealing and housing between to ask
Topic, and isolated the independent transmission supporting power and housing between, prevent test section that gravitational load is delivered in room housing.
The present invention seeks to realized by following technical measures：
This kind be used for wind-tunnel in independence support and pressure-bearing shell between sealing structure it is characterised in that：This structure bag
Include an independent test section platform (1) supporting, this test section platform (1) is by the column through wind tunnel reservoir structure room (2) housing (3)
(4) support, the bottom of column (4) is contacted with ground, column (4) passes through and welds on the edge in wind tunnel reservoir structure room (2) housing (3) place hole
One section of vertical pipeline (5), the bottom of pipeline (5) connects the upper end of self-balancing expansion joint (6), self-balancing expansion joint by flange
(6) lower end is connected by flange with the side wall of column (4).Rubber slab is adopted to seal on the joint face of flange.
In technical solution of the present invention, housing (3) closed test section platform (1) of the pressure-bearing in continous way transonic wind tunnel and
Self gravitation is not delivered to housing (3) above, but is supported by the independence being isolated with housing (3) and be directly delivered to ground
On the basis of face.The independent sealing structure supporting and pressure-bearing shell (3) between both can guarantee that independent support and shell under operating condition of test
Seal between body, malleation and negative pressure can also be born simultaneously.Generally the independent column (2) supporting is column type, to ensure
Independent support can conveniently be dismantled and pressure-bearing shell (3) between and be safeguarded.
In technical solution of the present invention, the use of self-balancing expansion joint (6) had both prevented pressure-bearing shell (3) and independent support
Between power transmission, also assures that sealing between the two, self-balancing expansion joint (6) allows lateral displacement, to sealing structure simultaneously
Stablize and have positive benefit.When self-balancing expansion joint (6) or sealing ring need to change, need only arrange temporary support will be independent
Supporting construction jack-up, then removes conversion bearing (7) it is possible to easily change self-balancing expansion joint (6) or sealing ring.

Specific embodiment
Below with reference to drawings and Examples, technical solution of the present invention is further described：
Referring to shown in accompanying drawing 1～3, the independence that this kind is used in wind-tunnel supports the sealing structure and pressure-bearing shell between, its
It is characterised by：This structure includes an independent test section platform 1 supporting, and this test section platform 1 is by through wind tunnel reservoir structure room 2 housing
3 column 4 supports, and the bottom of column 4 is contacted with ground, and column 4 passes through and welds one on the edge in hole at the housing 3 of wind tunnel reservoir structure room 2
Section vertical pipeline 5, the bottom of pipeline connects upper end, the lower end of self-balancing expansion joint and the column of self-balancing expansion joint by flange
Side wall connected by flange.Rubber slab is adopted to seal on the joint face of flange.
In this structure, the housing 3 of wind tunnel reservoir structure room 2 pressure-bearing and column 4 are all welded using steel plate, its central post 4 with perpendicular
Gap between straight pipeline 5 is 100mm, and the pressure that bears of self-balancing expansion joint 6 is 6atm, meets wind tunnel reservoir structure room 2 and the external world
4atm pressure reduction, the axially adjustable amount of self-balancing expansion joint 6 is 30mm, and the amount of laterally adjusting is 20mm, both direction adjustment amount
Meet the deformation difference between housing 3 and independent support, the independent column 4 supporting is divided into upper and lower two parts, and top and the bottom adopt
The connected mode that pin 8 is coordinated with hole, bottom can be dismantled, it is possible to achieve self-balancing expansion joint is changed.
Compared with existing apparatus, the advantage of technical solution of the present invention is：
1. ensure that independent support post and stay sealing between room housing；
2. the self-balancing expansion joint passing through column with housing upper face pipeline is flexibly connected, and solves to stay room and independent support because of heat
Swollen shrinkage and the deflection that produces is inconsistent and produce additional stress.
3. pass through the self-balancing expansion joint flexible connection of column and housing upper face pipeline, solve in room housing and test section
Between vibration conducting problem；
4. because expansion joint is matured product, conveniently purchase and install, facilitate later stage maintenance and safeguard.
