Abstract
The utility model provides a low speed wind tunnel contraction section panel turnover mechanism, includes contraction section, cylinder, crank, pivot, connection elbow, turns over the board and remain silent the test section, the cylinder is installed in contraction section upper end, and cylinder front end ear seat passes through the crank to be connected with the pivot, the pivot through connection elbow with turn over board one end and be connected, turn over the board other end and be connected with the test section of remaining silent, the removal section and the fixed back that targets in place of locking of canned paragraph of contraction section, the cylinder pole of cylinder is flexible, and flexible cylinder pole drives through crank, pivot and connection elbow and turns over firm and hard at present opening and the closure state. The utility model discloses can open or the board is turned over to the closure fast, can realize the change of switching mouth test section when opening, and the clearance that can well realize when closing remaining silent between test section and the contraction section is sealed, uses convenient operation, simple, has the advantage that improves wind -tunnel test efficiency, energy saving and consume.
Description
Technical field
The utility model relates to low-speed wind tunnel field, is specifically related to a kind of low-speed wind tunnel contraction section panel turnover mechanism.
Background technology
Along with the development of science and technology, cradle---the wind-tunnel that aerospace flight vehicle is born, has had application space more and more widely.Not only aircraft will " be dried ", nowadays automobile, building, bridge, and even sportsman also will test in wind-tunnel, and wind-tunnel technique is extended to all trades and professions from aerospace field.
For adapting to development and the development of aerospace flight vehicle, countries in the world have built the wind-tunnel of many various sizes and type in succession.Construction of wind tunnel is designed to cases of otherwise standard design, and different wind-tunnel has different structural shapes.Along with the development of computer technology and software engineering, modern structure designing technique continues to bring out, and construction of wind tunnel design must introduce a new concept, new thought, makes its structural design more reasonable.
Summary of the invention
The purpose of this utility model is to provide a kind of low-speed wind tunnel contraction section panel turnover mechanism, for sealing the gap of remaining silent between test section and contraction section.
The technology that the utility model adopts is as follows:
A kind of low-speed wind tunnel contraction section panel turnover mechanism, comprises contraction section, cylinder, crank, rotating shaft, bridge piece, turnover panel and test section of remaining silent; Cylinder is installed on contraction section upper end, and cylinder front end ear seat is connected with rotating shaft by crank, and rotating shaft is connected with turnover panel one end by bridge piece, and the turnover panel other end is connected with test section of remaining silent; After the mobile section of contraction section and canned paragraph fixing and locking put in place, the cylinder rod of cylinder stretches, and flexible cylinder rod drives turnover panel to realize opening and closure state by crank, rotating shaft and bridge piece.
Feature of the present utility model and advantage:
The utility model provides a kind of low-speed wind tunnel contraction section panel turnover mechanism, can open fast or closed turnover panel, the replacing of opening and closing mouth test section can be realized when opening, the clearance seal of remaining silent between test section and contraction section can be realized well during closedown, use convenient and simple for operation, there is the advantage improving wind tunnel test efficiency, economize energy consumption.
Accompanying drawing explanation
Fig. 1 is front view under panel turnover mechanism closure state.
Fig. 2 is front view under reverse turning bed structure open mode.
Embodiment
Further illustrate according to Figure of description citing below:
As shown in Figure 1-2, a kind of low-speed wind tunnel contraction section panel turnover mechanism, comprises contraction section 1, cylinder 2, crank 3, rotating shaft 4, bridge piece 5, turnover panel 6 and test section 7 of remaining silent; Cylinder 2 is installed on contraction section 1 upper end, and cylinder 2 front end ear seat is connected with rotating shaft 4 by crank 3, and rotating shaft 4 is connected with turnover panel 6 one end by bridge piece 5, and turnover panel 6 other end is connected with test section 7 of remaining silent; After the mobile section of contraction section 1 and canned paragraph fixing and locking put in place, rapid-acting coupling is used to obtain pressurized air from experiment hall pressurized air pipe well, pressurized air enter cylinder 2 realize cylinder rod stretch, flexible cylinder rod drives turnover panel 6 to realize opening and closure state by crank 3, rotating shaft 4 and bridge piece 5, two cylinders 2 form one group, common driving one group of turnover panel 6, often organizes cylinder 2 and uses a solenoid directional control valve driving to be synchronized with the movement; Throttling valve is used for realizing turnover panel 6 and steadily opens with closed, when turnover panel 6 is opened, changing opening and closing mouth test section and carries out corresponding opening test or test of remaining silent, when turnover panel 6 closes, realizing the clearance seal to remaining silent between test section 7 and contraction section 1.
