Description

Technical Field

[0001] This utility model belongs to the technical field of bridge experimental devices, specifically an experimental device for multi-physics field coupling of bridge structures. Background Technology

[0002] In real-world environments, bridges are simultaneously affected by a variety of natural factors such as wind, sunlight, rainfall, and water waves. To study the effects of these factors on bridge structures, laboratories typically set up different simulation devices to apply environmental loads such as wind, sunlight, rainfall, and waves to bridge specimens. Currently, most common experimental devices are arranged separately. For example, fans are used to generate wind, fluorescent lights are used to simulate solar radiation, sprinklers are used to create rainfall, and water tanks are used to generate waves. These devices are usually installed using their own independent brackets or frame structures and can only operate independently in the experimental area. They cannot simultaneously apply multiple environmental loads in the same space. When it is necessary to simulate multiple environments at the same time, such as applying wind, rain, and sunlight at the same time, existing experimental devices often require a large space. The installation height, arrangement direction, and movement space of the devices are also prone to conflict. Since there is no unified bracket structure to support various devices, it is difficult for these devices to achieve overall installation and collaborative work in a limited experimental space. Problems such as insufficient range of action, overlapping or interference between devices often occur. Most existing experimental platforms can only simulate a single environment, such as wind field test, solar radiation test, or rainfall test. If multiple environments are to be applied simultaneously, multiple devices need to be installed separately. The structures are scattered and occupy a large area, which is not suitable for achieving combined loading of multiple environments in a limited experimental space. Since these devices are installed separately without a unified installation framework, the arrangement of the devices in terms of height, width, and movement space often affects each other. It is difficult to ensure that the areas affected by wind, rain, solar radiation, and waves completely cover the bridge specimen. It also easily causes spatial conflicts and inconvenience in the arrangement of the devices. Therefore, how to enable devices such as wind, rain, sunlight, and waves to be installed within the same support system and to act simultaneously on bridge specimens in a limited experimental space, without the functional deficiencies caused by dispersed arrangement, is a technical problem that urgently needs to be solved by existing technologies. Utility Model Content

[0003] The purpose of this invention is to address the problem in the existing technology of how to install devices such as wind, rain, sunlight and waves within the same support system and simultaneously act on bridge specimens in a limited experimental space, so as to avoid the problem of incomplete functionality caused by dispersed arrangement, and to set up an experimental device for multi-physics coupling of bridge structures.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An experimental device for multi-physics coupling of bridge structures includes a spray device, a sunlight device, and a wave device. The spray device and the sunlight device are connected by columns to form an integral support system. The wave device is set in the space area enclosed by the columns. The spraying device includes a rectangular support and a spray beam mounted on the rectangular support, and the spray beam is provided with multiple nozzles; The solar lighting device includes an arc-shaped track mounted above the rectangular support, and multiple arc-shaped buckles connected to the arc-shaped track, the arc-shaped buckles being used to install solar lamps; The arc-shaped track has a height interval relative to the spray beam, and the lowest point of the daylight lamp is located above the top surface of the rectangular bracket; The coverage area of ​​the solar radiation device is larger than the spraying area of ​​the sprinkler device.

[0005] Preferably, the spray beam is perpendicular to the opposite side of the rectangular support, and the installation height of the spray beam is lower than the lowest point of the arc-shaped track.

[0006] Preferably, the spray beam is slidably connected to the rectangular support.

[0007] Preferably, the extension direction of the arc-shaped track is perpendicular to the extension direction of the spray beam.

[0008] Preferably, the end of the arc-shaped track is connected to the top of the column, and the arc-shaped track spans above the rectangular support.

[0009] Preferably, a telescopic rod is provided between the arc-shaped buckle and the daylight lamp, and the telescopic rod is used to adjust the installation height of the daylight lamp.

[0010] Preferably, the wave generator includes a fan and a wave-generating tank, the wave-generating tank being located on the ground within the space enclosed by the rectangular support, and the fan being arranged around the wave-generating tank.

[0011] Preferably, the column includes a base and a column rod, one end of the column rod is connected to the arc-shaped track, and the other end is connected to the base, with the base in contact with the ground.

[0012] Preferably, a water storage tank is provided on the side of the column, and the water storage tank is connected to the spray head through a water pipe. The water pipe is arranged along the column and through the rectangular bracket and the spray beam to fit the bracket structure.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The unified support system described in this utility model, through the staggered arrangement of the spray device, the sunlight device and the wind and wave device, enables multiple physical fields to be applied to the bridge specimen in the same space in a coordinated manner. This solves the problem of the dispersed arrangement of devices and the inability to achieve simultaneous loading of multiple fields in the prior art, and realizes the centralized simulation of environments such as wind, rain, sunlight and water waves, greatly improving the utilization rate of experimental space. 2. The height interval, vertical orientation, and sliding adjustment structure between the spray beam, the arc track, and the solar lamp described in this utility model ensure a stable spray path, unrestricted adjustment of the solar lamp angle, and flexible adjustment of the spray range according to different specimen sizes. This effectively avoids interference between the spray and solar systems, and improves the coordination and loading accuracy during multi-physics superposition experiments.

[0014] 3. The wind and wave device, the column support structure, and the close arrangement of the water storage tank and the water pipeline described in this utility model enable the fan, the wave-generating water tank, and the spray device to form an orderly layout in a unified space. This not only ensures the continuity of wind and wave loading but also avoids cross-interference between the pipeline and the operating areas of the solar lamp and the fan, thereby further enhancing the stability and reliability of the entire multiphysics loading system.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In Example 1: The experimental device for multi-physics coupling of bridge structures described in this utility model includes a spray device 1, a sunlight device 2, and a wave device 3. The spray device 1 and the sunlight device 2 are connected by a column 4 to form an integral support system. The wave device 3 is set in the space area enclosed by the column 4. The spray device 1 includes a rectangular support 5 and a spray beam 6 mounted on the rectangular support 5. The spray beam 6 is provided with multiple nozzles 7. The sunlight device 2 includes an arc-shaped track 8 mounted above the rectangular support 5 and multiple arc-shaped buckles 9 connected to the arc-shaped track 8. The arc-shaped buckles 9 are used to install sunlight lamps 10. The arc-shaped track 8 has a height interval relative to the spray beam 6. The lowest point of the sunlight lamp 10 is located above the top surface of the rectangular support 5. The coverage area of ​​the sunlight device 2 is larger than the spray area of ​​the spray device 1.

[0024] In this embodiment, the spraying device 1 and the sunlight device 2 are combined into a unified support structure by the column 4, forming a spatial system with staggered upper and lower layers. The spraying beam 6 is located in the lower layer, the arc track 8 is located in the middle layer, and the sunlight lamp 10 is located in the upper layer. This spatial arrangement allows each device to be installed in layers within the same test area, avoiding mutual interference. This enables multiple physical fields such as wind, rain, sunlight, and waves to act on the same bridge specimen in a common space, solving the problem of dispersed device arrangement and inability to uniformly load functions in the prior art. At the same time, through the spatial coordination of height intervals and coverage range, the spraying beam 6 is prevented from being blocked by the sunlight lamp 10 during spraying, and the movement or angle adjustment of the sunlight lamp 10 will not interfere with the spraying trajectory, thereby maintaining the spraying stability and sunlight continuity under multi-field loading conditions, and thus maintaining the functional synergy between the multi-physical field loading system.

[0025] In Example 2: The experimental device for multi-physics coupling of bridge structures described in this utility model, based on the above method, further specifies that the spray beam 6 is perpendicular to the opposite sides of the rectangular support 5, and the installation height of the spray beam 6 is lower than the lowest point of the arc-shaped track 8. With this structural arrangement, the spray direction forms a fixed geometric relationship with the edge line of the rectangular support 5, thereby effectively maintaining the stability of the spray path. Simultaneously, the spray beam 6 being lower than the arc-shaped track 8 effectively reduces the impact on the spray device 1 when adjusting the daylight lamp 10.

[0026] As a preferred embodiment, based on the above method, the spray beam 6 is further slidably connected to the rectangular support 5. This structural arrangement allows the spray beam 6 to move along the direction of the rectangular support 5, thereby adapting to the width or position of different bridge models and further adjusting the spray range.

[0027] As a preferred embodiment, based on the above method, the extension direction of the arc-shaped track 8 is further arranged perpendicular to the extension direction of the spray beam 6. This structural arrangement effectively maintains the orthogonality between the light movement direction and the spray direction, ensuring that the daylight lamp 10 does not compress its spray arrangement space along the spray direction when adjusted. This allows the two systems to have their own independent movement paths within a limited space, avoiding a reduction in the effective arrangement space of the device due to overlapping directions.

[0028] As a preferred embodiment, based on the above method, the end of the arc-shaped track 8 is connected to the top of the column 4, and the arc-shaped track 8 spans above the rectangular support 5. This structural arrangement allows the solar lamp 2 to span above the sprinkler device 1, giving the solar lamp 10 a complete range of movement within the test area. Simultaneously, the column 4 provides reliable support for the arc-shaped track 8, helping to maintain the stability of the solar lamp 10 during operation.

[0029] In Example 3: The experimental device for multi-physics coupling of bridge structures described in this utility model, based on the above method, further includes a telescopic rod 11 between the arc-shaped buckle 9 and the daylight lamp 10. The telescopic rod 11 is used to adjust the installation height of the daylight lamp 10. With this structural arrangement, the illumination angle and height of the daylight lamp 10 can be adjusted according to the actual size of the bridge model and experimental requirements, thereby improving the uniformity of illumination and the accuracy of the experimental simulation.

[0030] As a preferred embodiment, based on the above method, the wind and wave device 3 further includes a fan 12 and a wave-generating water tank 13. The wave-generating water tank 13 is located on the ground within the space enclosed by the rectangular support 5, and the fan 12 is arranged around the wave-generating water tank 13. With this structural arrangement, the fan 12 is arranged around the wave-generating water tank 13, which can realize wind and wave coupled loading. The wave-generating water tank 13 is located within the area enclosed by the rectangular support 5. This arrangement allows the wind field and water waves to act on the bridge specimen in the same area, and at the same time, it forms a multi-physics superposition loading system with the spray device 1 and the sunlight device 2.

[0031] As a preferred embodiment, based on the above method, the column 4 further includes a base 14 and a column rod 15. One end of the column rod 15 is connected to the arc-shaped track 8, and the other end is connected to the base 14, which is in contact with the ground. This structural arrangement, through the connection of the base 14 and the column rod 15, provides stable support for the solar radiation device 2 and the spray device 1, which helps maintain the stability of the overall structure under multi-physics loading conditions and reduces the impact of vibration or tilt on the test accuracy.

[0032] As a preferred embodiment, based on the above method, a water storage tank 16 is further provided on the side of the column 4. The water storage tank 16 is connected to the nozzle 7 through a water pipe 17. The water pipe 17 is arranged along the column 4 and passes through the rectangular bracket 5 and the spray beam 6 to fit the bracket structure. With this structural arrangement, the water pipe 17 is arranged along the bracket structure, keeping it away from the irradiation path of the solar radiation device 2 and the main air duct area of ​​the fan 12. This helps to prevent the water pipe 17 from entering the multi-physics loading space, thereby maintaining the superposition stability of the multi-physics in the test area.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
