Description

Technical Field

[0001] This invention relates to the field of bridge and structural engineering technology, and in particular to an adjustable flow deflector device. Background Technology

[0002] With the rapid development of modern civil engineering technology, bridge spans and building heights are constantly increasing, and structures are showing a trend towards lightweight and flexible designs. Wind-induced vibration is becoming increasingly prominent, posing a key dynamic challenge in bridge and structural design. Vortex-induced resonance and flutter instability are the two most concerning wind-induced vibration phenomena in wind-resistant design. Vortex-induced resonance often occurs in components such as railings, cables, hangers, bridge towers, and main beams. Its vibration frequency is close to the structure's natural frequency, easily leading to cumulative fatigue damage and affecting driving safety and comfort. Flutter, on the other hand, is a divergent self-excited vibration that occurs under high wind speeds, which can cause severe structural vibrations or even damage, seriously threatening the safety and operational stability of bridges and structures. To effectively suppress vortex-induced vibration amplitude and increase the flutter critical wind speed, engineering practice often employs structural, aerodynamic, and mechanical measures to optimize the aerodynamic shape of the structure. By improving the airflow distribution on the windward and leeward sides, delaying or avoiding flow separation, reducing the size of separated vortices, and disrupting the regular shedding of vortices, the wind resistance performance of the structure is significantly improved. Aerodynamic measures offer advantages such as cost-effectiveness and ease of implementation. Common forms include deflectors, baffles, flow dividers, central stabilizing plates, and central slots. However, traditional aerodynamic measures are mostly permanent installations, lacking flexibility and making it difficult to adapt to varying operating conditions and seasonal wind environments.

[0003] Meanwhile, the impact of wind conditions on bridge decks and buildings on driving safety and passenger comfort is also a crucial aspect of wind-resistant design for wind-sensitive structures. Reasonable control of wind speed on bridge decks is essential for ensuring vehicle stability and passenger safety. Traditionally, vertical wind barriers are installed at pedestrian height to reduce local wind speeds. However, traditional vertical wind barriers have several limitations: firstly, their considerable height and vertical arrangement significantly increase the lateral wind load on the main structure, dulling its aerodynamic profile and potentially worsening vortex-induced vibration and flutter performance; secondly, permanently installed wind barriers cannot be adjusted or dismantled according to actual wind conditions and operational needs, remaining even in low-wind-speed conditions where wind protection is not required, resulting in resource waste and potentially negatively impacting the overall aerodynamic performance of the structure. Furthermore, the presence of fixed wind barriers can cause inconvenience during bridge and structure inspections, maintenance, or special operations. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an attitude-adjustable flow deflector device.

[0005] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0025] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0026] Please see Figure 1 , Figure 2 This application discloses an adjustable flow deflector device, including a flow deflector 1, a first telescopic support assembly, and a second telescopic support assembly. The first telescopic support assembly is disposed on the lower part of one side of the flow deflector 1, and includes at least one first telescopic support rod 2. One end of the first telescopic support rod 2 is fixedly connected to the flow deflector 1, and the other end is connected to a first locking member. The second telescopic support assembly is disposed on the lower part of one side of the flow deflector 1 and is located below the first telescopic support assembly. The second telescopic support assembly includes at least one second telescopic support rod 3, one end of the second telescopic support rod 3 is rotatably connected to the flow deflector 1, and the other end is rotatably connected to a second locking member.

[0027] In this embodiment, the first telescopic support assembly includes two first telescopic support rods 2 arranged horizontally at intervals relative to each other, and the second telescopic support assembly includes two second telescopic support rods 3 arranged horizontally at intervals relative to each other, thereby improving the stability of the connection between the first telescopic support assembly and the second telescopic support assembly and the railing, and at the same time improving the stability of the support for the flow deflector 1.

[0028] Preferably, the distance between one end of the first telescopic support rod 2 and the center line of the flow deflector 1 is less than the distance between one end of the second telescopic support rod 3 and the center line of the flow deflector 1. This arrangement avoids interference from the first telescopic support rod 2 when adjusting the position of the second telescopic support rod 3, ensuring the ease of adjusting the position of the second telescopic support rod 3.

[0029] To facilitate the rotation of the second telescopic support rod 3 relative to the flow deflector 1, it is preferable that one end of the second telescopic support rod 3 is hinged to the flow deflector 1 via the first ball joint 4, which facilitates the rapid adjustment of the angle of the flow deflector 1.

[0030] Preferably, a second ball joint 5 is provided between the other end of the second telescopic support rod 3 and the second locking member, which facilitates the rotation of the second locking member relative to the second telescopic support rod 3, thereby making it easier to adjust the position of the second locking member and thus quickly install it in different positions of the railing, while being suitable for different railings.

[0031] To facilitate adjustment of the length of the first telescopic support rod 2, it is preferable that the first telescopic support rod 2 includes at least two first telescopic support rod bodies 21, and a first locking buckle 22 is provided on two adjacent first telescopic support rod bodies 21. The first locking buckle 22 can be a bolt, allowing one of the first telescopic support rod bodies 21 to move within the other first telescopic support rod body 21. By passing the bolt through the other first telescopic support rod body 21, the bolt secures one of the first telescopic support rod bodies 21 that extends into the other first telescopic support rod body 21, thereby determining the length of the first telescopic support rod 2.

[0032] To facilitate adjustment of the length of the second telescopic support rod 3, it is preferable that the second telescopic support rod 3 includes at least two second telescopic support rod bodies 31, and a second latch 32 is provided on two adjacent second telescopic support rod bodies 31. The second latch 32 can be a bolt, allowing one of the second telescopic support rod bodies 31 to move within the other. By passing the bolt through the other second telescopic support rod body 31, the bolt secures the one second telescopic support rod body 31 that extends into the other, thereby determining the length of the second telescopic support rod 3.

[0033] Preferably, the first locking element includes a first electric gripper 6, and the second locking element includes a second electric gripper 7, enabling quick gripping or release of the railing at appropriate positions. The first electric gripper 6 can release or grip the first gripper body 61 through a first motor rack and pinion mechanism 60, and the second electric gripper 7 can release or grip the second gripper body 72 through a second motor rack and pinion mechanism 70.

[0034] In this embodiment, the first electric gripper 6 is preferably locked to the crossbeam 81 of the railing 8, and the second electric gripper 7 is locked to the post 82 of the railing 8. Of course, it can be understood that since the second electric gripper 7 can rotate relative to the second telescopic support rod 4, the second electric gripper 7 can quickly adjust its position, so that the second electric gripper 7 can also be locked to other positions of the railing 7.

[0035] The dimensions of the deflector 1 can be calculated and set based on wind tunnel test results, and the pitch angle of the deflector 1 can be determined according to actual needs. The pitch angle refers to the angle A between the deflector 1 and the bridge deck. In use, the distance between the deflector 1 and the railing 8 is adjusted by placing the first telescopic support rod 2 at a suitable length. Simultaneously, the first electric gripper 6 is positioned appropriately to ensure it can grip the crossbeam 81 of the railing 8 for installation of the deflector 1. Then, the second telescopic support rod 3 is allowed to rotate freely via the first ball joint 4, extending or shortening its length to a suitable position. The second electric gripper 7 is then rotated and repositioned via the second ball joint 5. Next, the second electric gripper 7 is activated, causing its body 71 to grip the post 82 of the railing 8. Finally, the first electric gripper 6 is activated, causing its body 61 to grip the crossbeam 81 of the railing 8. At this point, the entire deflector device is installed and fixed. The pitch angle of the deflector 1 can be adjusted according to the specific wind conditions on the bridge deck. Extending the second telescopic support rod 3 decreases the pitch angle of the deflector 1; shortening the second telescopic support rod 3 increases the pitch angle of the deflector 1. By precisely calibrating the first deflector device, subsequent deflector devices can be aligned with the first deflector device to achieve the installation of multiple deflector devices.

[0036] The deflector device can be temporarily installed on the bridge railing 8 and remain stationary at any tilt angle to achieve normal working posture. When the bridge is prone to vortex-induced vibration under low wind speeds, the distance between the first telescopic support rod 2 and the railing 8 can be controlled by adjusting the length of the first telescopic support rod 2. The pitch angle of the deflector 1 can be controlled by adjusting the length of the second telescopic support rod 3. After determining the pitch angle of the deflector 1, the first electric clamp 6 is locked to the crossbeam 81 of the railing 8, and the second electric clamp 7 is locked to the column 82 of the railing 8. The deflector 1 can change the wind environment of the bridge and structure and prevent vortex-induced vibration. When the safety of vehicles and personnel is reduced under high wind speeds, the length of the second telescopic support rod 3 can be adjusted to raise the deflector 1. At this time, it is similar to a wind barrier on both sides of the road, which helps to improve the comfort of vehicles and personnel.

[0037] When the wind speed at the construction site is high, the deflector 1 should be adjusted to a horizontal position to reduce static wind resistance.

[0038] When the bridge structure experiences vortex-induced vibration under moderate wind speeds, in order to ensure the safety of vehicles and personnel, the length of the second telescopic support rod 3 is adjusted to raise the deflector plate 1, enabling it to function as a deflector plate, changing the frequency of airflow vortex shedding as it passes over the bridge cross section, improving aerodynamic characteristics, and suppressing vortex-induced vibration.

[0039] When the wind speed is outside the vortex-induced vibration range of the bridge or building structure, the deflector device can be disassembled. Additionally, the deflector device can also be disassembled when cleaning, repairing, or replacing worn parts of the deflector 1 surface is required. The deflector device can be disassembled by releasing the first gripper body 61 of the first electric gripper 6 from the crossbeam 81 of the railing 8, and simultaneously releasing the second gripper body 71 of the second electric gripper 7 from the post 82 of the railing 8.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider 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.
