[0002] A diversion wall is a wake protection device applied in the field of engine test runs. When in use, it is placed behind the tail nozzle of a starting engine. When the engine wake blows through the spaces between the diversion wall blades, it can change the air flow direction and effectively reduce the wind speed in the area below the vertical height of the diversion wall, achieving the function of protecting the personnel, vehicles, and buildings behind the diversion wall.

[0003] Among them, the core component of the diversion wall is the diversion blade. The traditional connection method between the diversion blade and the structural frame is welding. However, since the wind pressure and vibration borne by the diversion blade when being impacted by the aircraft wake are relatively large, the traditional connection method is not conducive to the release of the stress of the diversion wall, thereby reducing the structural strength and service life of the product.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0029] As Figure 1-4 shown, the present utility model provides a flow guiding wall blade connection structure with a stress resistance function, including two steel structure support members 1 that are parallel to each other and inclined, a horizontally arranged flow guiding vane 2 is provided between the steel structure support members 1, and the flow guiding vanes 2 are arranged at intervals along the length direction of the steel structure support members 1; wherein, a connecting member 3 is provided at the connection between the flow guiding vane 2 and the steel structure support member 1, and the connecting member 3 is detachably and fixedly connected to the flow guiding vane 2 and / or the steel structure support member 1 through a locking member 4;

[0030] In the existing flow guiding wall structure, the steel structure support member 1 and the flow guiding vane 2 are usually connected by welding. After long-term use, it is found that cracks are likely to appear on the flow guiding vane 2 near the connection between the two. This is because the flow guiding vane 2 vibrates and even deforms under the impact of the wake flow, resulting in cracks or even fractures on the flow guiding vane 2. In order to effectively solve this problem, the present utility model arranges the connecting member 3 between the flow guiding vane 2 and the steel structure support member 1 for connection, so that the flow guiding vane 2 and the steel structure support member 1 are allowed to vibrate within a certain range to release the stress caused by the wake flow, thereby overcoming the problem that the flow guiding vane 2 is prone to cracks, and further improving the service life and overall structural strength of the flow guiding wall;

[0031] It should be noted that stress refers to the internal force generated between various parts of an object when the object deforms due to external factors (such as force, humidity, temperature field change, etc.), so it is easy to cause the steel structure support member 1 and the flow guiding vane 2 connected by welding or the flow guiding vane 2 itself to break;

[0032] Preferably, to ensure the connection stability and installation convenience between the steel structure support member 1 and the guide vane 2, the locking member 4 is a bolt and nut. Compared with the welding structure in the prior art, through the arrangement of the connecting member 3 and the locking member 4, the steel structure support member 1 and the guide vane 2 can be disassembled more flexibly while effectively releasing stress.

[0033] Specifically, as Figure 3-4 shown, for better guiding and fixing effects, the steel structure support member 1 and the guide vane 2 usually adopt a connection structure that is perpendicular or nearly perpendicular to each other. Therefore, the connecting member 3 needs a bending portion to enable it to respectively adapt to the installation surfaces of the steel structure support member 1 and the guide vane 2. That is to say, the connecting member 3 includes a first connecting portion 31 and a second connecting portion 32, and the first connecting portion 31 and the second connecting portion 32 are integrally formed and intersect with each other by bending; through the integrally formed setting of the first connecting portion 31 and the second connecting portion 32, its connection stability and its own structural strength are effectively improved; at the same time, for improving the production convenience, the first connecting portion 31 and the second connecting portion 32 can also be welded to form the connecting member 3 integrally;

[0034] Furthermore, the guiding of the guide vane 2 is to guide the horizontal wake to the upper oblique direction, so as to play a role in protecting the people or objects behind the guiding wall. To achieve this guiding effect, the guide vane 2 can be an arc-shaped plate or a flat plate arranged obliquely. At the same time, in order to better adapt the guide vane 2 to the connecting member 3, the first connecting portion 31 is an arc-shaped plate or a flat plate corresponding to the guide vane 2; when the connecting member 3 is connected to the guide vane 2, the guide vane 2 can be attached to the upper end surface or the lower end surface of the first connecting portion 31, and then locked and fixed by the locking member 4, so as to improve the connection stability between the guide vane 2 and the connecting member 3.

[0035] In order to more clearly express the technical solution of the present invention, the following provides three embodiments;

[0036] In the first embodiment, as Figure 5 shown, the first connecting portion 31 of the connecting member 3 is integrally formed with the guide vane 2, and the second connecting portion 32 is attached to the steel structure support member 1 and is detachably fixedly connected through the locking member 4; since the second connecting portion 32 and the steel structure support member 1 are detachably connected, the stress of the guide vane 2 can also be effectively released, thereby improving the use stability and service life of the guide vane 2; at the same time, through the integrally formed design of the first connecting portion 31 and the guide vane 2, not only the self-structural strength of the guiding wall is effectively improved, but also the installation convenience and production efficiency of the guide vane 2 and the connecting member 3 are improved.

[0037] In the second embodiment, as Figure 6 shown, the flow guiding vane 2 is attached to the top or bottom surface of the first connecting portion 31 and is detachably and fixedly connected by the locking member 4. The second connecting portion 32 is attached to the steel structure support member 1 and is detachably and fixedly connected by the locking member 4. By detachably connecting the connecting member 3 to the flow guiding vane 2 and the steel structure support member 1 respectively, the stress release efficiency is improved, and thus the service life of the flow guiding vane 2 is effectively increased.

[0038] In the third embodiment, as Figure 7 shown, the second connecting portion 32 of the connecting member 3 is integrally formed with the steel structure support member 1. The flow guiding vane 2 is attached to the top or bottom surface of the first connecting portion 31 and is detachably and fixedly connected by the locking member 4. Through the integrally formed design of the second connecting portion 32 and the steel structure support member 1, the connection stability between the steel structure support member 1 and the connecting member 3 can be improved. At the same time, the detachable connection between the flow guiding vane 2 and the connecting member 3 can also effectively release stress and is more convenient to install.

[0039] Specifically, as Figure 6-7 shown, in order to further fully absorb the torsional force and vibration borne by the flow guiding vane 2 during the flow guiding process to release the stress on the flow guiding vane 2, in the second and third embodiments, an elastic gasket 5 is further provided between the first connecting portion 31 and the flow guiding vane 2. The elastic gasket 5 has a buffering effect, which can not only effectively relieve vibration to release stress and increase the service life, but also has the effect of eliminating noise;

[0040] Preferably, the elastic gasket 5 is made of rubber damping material.

[0041] Specifically, as Figure 8 shown, in order to improve the overall fixing effect and service stability of the diversion wall, longitudinal support rods 11 and transverse support rods 12 are further provided on the steel structure support member 1. The longitudinal support rods 11 are vertically arranged on the ground, one end of which is fixedly connected to the steel structure support member 1 and the other end is fixedly connected to the ground, so as to provide a better fixing effect for the obliquely arranged steel structure support member 1 to resist the impact of the wake flow; one end of the transverse support rod 12 is fixedly connected to the steel structure support member 1 and the other end is fixedly connected to the longitudinal support rod 11. Through the arrangement of the transverse support rod 12, the land stability of the steel structure support member 1 is further improved;

[0042] Furthermore, in order to improve the overall connection stability of the longitudinal support rods 11 and the transverse support rods 12, the longitudinal support rods 11 and the transverse support rods 12 are arranged perpendicular to each other.

[0043] The working principle of the present utility model will be described in detail below;

[0044] In use, first fix the pairwise-opposed steel structure supports 1 to the ground through the transverse support rods 12 and longitudinal support rods 11. Then, install the flow guiding vanes 2 between the two steel structure supports 1 through the connecting members 3. Finally, arrange multiple groups of the steel structure supports 1 and the flow guiding vanes 2 side by side to form a flow guiding wall, so as to increase the flow guiding area. At this time, the wake flow horizontally facing the flow guiding wall is discharged obliquely upward under the action of the flow guiding vanes 2, thereby achieving the function and purpose of flow guiding.

[0045] The innovation of the present utility model lies in that a connecting member is screwed at the connection between the flow guiding vane and the steel structure support, which is convenient for disassembling the component structures of the flow guiding wall for transportation and can achieve rapid installation, improving the installation and construction efficiency of the flow guiding wall. At the same time, by designing the connecting member into two parts and respectively fitting them to the flow guiding vane and the steel structure support, and arranging an elastic gasket at the connection, the torsional force borne by the flow guiding vane during the flow guiding process can be fully absorbed to release the stress on the flow guiding vane, thereby enhancing the overall structural strength of the flow guiding wall and effectively extending the service life of the flow guiding wall.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0047] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
