Description

Technical Field

[0001] The present invention relates to the technical field of marine engineering experiments, and in particular to a mid-span XY trailer device serving a wind-wave combined deepwater laboratory. Background Art

[0002] With the continuous development of deep-sea resources, the performance evaluation of marine structures such as ships and offshore platforms in complex marine environments has become crucial. In the actual ocean, these structures must withstand the combined effects of wind and waves. Therefore, simulating extreme marine conditions and conducting tests and verifications in laboratory environments have become important means of marine engineering research. As a core experimental facility, the test pool provides researchers with a controlled environment to study the impact of wind and waves on marine structures. The XY trailer device, as a key equipment in the test pool, undertakes important functions such as towing ship models, measuring and collecting data. Its performance directly affects the accuracy and reliability of the experiment.

[0003] However, with the increasing requirements of marine engineering experiments, the structural design of traditional XY trailer devices has been unable to meet modern experimental needs, especially in wind-wave combined deep-water laboratories, mainly facing the following technical problems:

[0004] 1. Limited Space Height: The wind and wave laboratory's pool is typically equipped with a large wind tunnel, which limits the available height of the experimental area. Traditional trailer-mounted structures (such as box-girder structures or hybrid box-girder-truss structures) have high trusses that are difficult to fit into the confined experimental space, limiting the feasibility and flexibility of the experiments.

[0005] 2. Severe wind field interference: In wind-wave combined experiments, the wind resistance of the trailer is particularly prominent. Traditional trailer structures (such as closed box girders) have a large frontal area facing the wind, which easily generates vortices in the wind field. This leads to uneven wind speed distribution above and below the structure, seriously affecting wind field uniformity and measurement accuracy. Furthermore, the high wind resistance increases experimental energy consumption and operating costs. Summary of the Invention

[0006] The purpose of the present invention is to provide a mid-support XY trailer device serving the wind-wave combined deep-water laboratory, which has a low wind resistance spatial grid system, can effectively disperse wind pressure, reduce vortex generation, and effectively meet the load-bearing requirements of the large-span water tank of the deep-water laboratory.

[0007] To achieve the above objectives, the technical solution of the present application is: a mid-span XY trailer device serving the wind-wave combined deepwater laboratory, comprising:

[0008] The auxiliary vehicle mechanism runs along the width of the pool. Its main frame is made of circular cross-section rods connected by welding. It is an open frame with an internal walkway.

[0009] The main vehicle mechanism runs along the length of the pool. Its spatial truss is made of circular cross-section rods connected by welding, and a hollow channel is provided inside to avoid the auxiliary vehicle mechanism.

[0010] As a preferred solution of the present invention, the auxiliary vehicle mechanism includes a driving device and a guiding device. The main frame is nested in the space truss. The main frame is connected with driving devices on all sides, and a guiding device is provided between two adjacent driving devices in the length direction.

[0011] As a preferred solution of the present invention, the main vehicle mechanism has a driving device and a guiding device. The driving devices are connected to the four sides of the spatial truss, and a guiding device is provided between two adjacent driving devices in the length direction.

[0012] As a preferred solution of the present invention, the driving device includes a DC motor, which is connected to the wheel through a reducer and a coupling in sequence.

[0013] As a preferred solution of the present invention, the guide device includes symmetrically arranged guide wheels, the guide wheels are connected to one end of the wheel axle, and the other end of the wheel axle is connected to the guide wheel seat through a bearing.

[0014] As a preferred solution of the present invention, the wheels of the main vehicle mechanism move on the main vehicle track, the guide wheels of the main vehicle mechanism roll in the grooves on both sides of the main vehicle track, and the main vehicle track is installed on the wall of the pool.

[0015] As a preferred solution of the present invention, the wheels of the auxiliary vehicle mechanism move on the auxiliary vehicle track, the guide wheels of the auxiliary vehicle mechanism roll in the grooves on both sides of the auxiliary vehicle track, and the auxiliary vehicle track is fixed on both sides of the hollow channel of the space truss.

[0016] As a preferred solution of the present invention, the space truss and the main frame are both provided with a cleaning device, and the cleaning device includes a brush installed on a cleaning disc, the cleaning disc is connected to the bottom of the support rod, and the top of the support rod is connected to the support.

[0017] As a preferred solution of the present invention, an electric control box is provided on one side of the main vehicle mechanism, and a controller connected to the DC motor is provided in the electric control box.

[0018] As a preferred solution of the present invention, the power supply system of the electric control box includes a safety busbar, a pantograph and a cable. Power is taken from the safety busbar through the pantograph and the cable, and supplied from the laboratory to the designated column head of the safety busbar.

[0019] Due to the adoption of the above technical solutions, the present invention can achieve the following technical effects: the main vehicle mechanism of the present application adopts a spatial truss as the core load-bearing frame, and all truss members adopt a streamlined circular cross-section design to form a low-wind-resistance spatial grid system. Compared with traditional box girders or hybrid structures, circular cross-section members can effectively disperse wind pressure and suppress vortex generation due to their excellent aerodynamic properties. According to actual measurements, wind resistance can be reduced by more than 25%. At the same time, the truss adopts a mid-support structural layout, and the auxiliary vehicle mechanism is embedded in the truss web area, which reduces the vertical height of the main vehicle by 30%, successfully solving the technical problem of limited height in the wind tunnel test area. In addition, this structural design can meet the load-bearing requirements of large-span water tanks in deep-water laboratories, ensuring that the trailer maintains stable operation and precise positioning under high wind speed and long-stroke conditions.

[0032] See also Figure 1-2 This embodiment provides a mid-span XY trailer device serving a wind-wave joint deepwater laboratory, comprising:

[0033] The main vehicle mechanism runs along the length of the pool and is a mid-span space truss made of welded circular cross-section rods. The truss has a hollow channel inside for the auxiliary vehicle mechanism to pass through, and drive devices are symmetrically arranged around it, such as Figure 3 As shown in Figure 1, each drive unit includes a DC motor, a reducer, a coupling and a wheel, forming a four-wheel four-drive power system. A guide device is set between adjacent drive units, such as Figure 4 As shown, the guide device includes a symmetrical guide wheel, a wheel axle, a guide wheel seat and a bearing. The guide wheel seat is installed on the space truss through a mounting base. The guide wheel is embedded in the grooves on both sides of the main vehicle track to ensure that there is no offset in the linear motion. The main vehicle track is installed on the wall of the pool and can include a rail seat, a steel rail, a customized adjustment bolt and a hydraulic buffer. The surface of the track is nitrided to improve wear resistance.

[0034] The auxiliary vehicle mechanism runs along the width of the pool. It is a main frame welded with circular cross-section rods, which is nested in the hollow channel of the space truss. The main frame adopts an open design, with a walkway inside for test personnel to install instruments and models. The drive device of the auxiliary vehicle is similar to the structure of the main vehicle. The auxiliary vehicle track is fixed on both sides of the hollow channel of the main vehicle truss, and the structure is consistent with the main vehicle track to ensure operation accuracy. Preferably, a lifting platform is set at the bottom of the auxiliary vehicle mechanism, which is controlled by a servo motor, and the servo motor is connected to the controller in the electric control box.

[0035] Cleaning devices are installed at the bottom of the main vehicle mechanism and the auxiliary vehicle mechanism, such as Figure 5 As shown, it includes a cleaning disc, a brush, a support rod and a support. The brush is in close contact with the track surface, automatically removing impurities on the track, reducing running resistance and extending the service life of the track. The support is fixed on the corresponding space truss and main frame.

[0036] The power supply system utilizes a combination of a safety busbar and a pantograph. The pantograph draws power from the busbar, and cables transmit the power to the trailer's various components. This design ensures stable power supply during long-distance travel, eliminating the risk of power outages.

[0037] As a preferred implementation scheme provided in this embodiment, the diameter of the circular cross-section rod is preferably 50-100 mm, and annular reinforcing ribs are welded at the connections between the rods to increase the overall bending stiffness and reduce wind resistance to meet the load-bearing requirements of large-span water tanks.

[0038] The benefits of this implementation are that the auxiliary carriage mechanism is nested within the main carriage mechanism, reducing the overall height by 30%, perfectly fitting within the space constraints of the wind tunnel test area. Combined with four-wheel drive and guide wheel constraints, linear motion deviation is minimal; a cleaning device reduces track wear and extends equipment life.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
