Description

Technical Field

[0001] This utility model relates to the field of water environment monitoring technology, specifically to a water flow observation device suitable for wave tests of marine floating structures. Background Technology

[0002] Marine floating bodies have wide applications in the field of marine engineering, covering offshore oil platforms, floating wind turbines, various buoys, and ships. Accurately understanding their performance under wave action is crucial. Wave physics model experiments, as a key research method, can intuitively demonstrate the impact of complex marine environments on floating bodies, providing indispensable basis for practical engineering design, safety assessment, and optimized operation.

[0003] However, in existing wave physics model experiments, there is limited analysis of the motion characteristics of the floating body at the water surface interface and below the water surface under the action of waves, which cannot reflect the propagation and motion pattern of water flow around the floating body. Utility Model Content

[0004] The purpose of this invention is to provide a water flow observation device suitable for wave testing of marine floating structures, in order to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A water flow observation device suitable for wave testing of marine floating structures includes a support rod with a movable cylinder slidably connected to it. Multiple legs are evenly distributed at the bottom of the support rod. A limiting component for limiting the height of the movable cylinder is provided on the outer wall of the support rod. A frame is provided at the top of the movable cylinder, and a waterproof cover is installed inside the frame. A camera device is installed inside the waterproof cover. Foam floating structures are provided on both sides of the frame. Each foam floating structure includes a foam board and a connecting rope. The foam board is fixedly connected to the connecting rope, and the connecting rope is fixedly connected to the side wall of the frame.

[0007] As the foam floating structure rises and falls with the water surface, the frame and the camera device inside it float accordingly.

[0008] As a preferred embodiment of this utility model, the number of foam floating structures is set to multiple, and the sides of two adjacent foam floating structures away from the frame are connected by connecting ropes.

[0009] As a preferred embodiment of this utility model, a water depth gauge is provided on the outer wall of the support rod, and the surface of the water depth gauge is coated with a waterproof coating.

[0010] As a preferred embodiment of this utility model, the limiting component includes a locking screw, a fixing screw hole is provided on the outer wall of the movable cylinder, the locking screw is threaded into the inside of the fixing screw hole, and a plurality of threaded grooves are evenly provided along the length direction on the side of the outer wall of the support rod near the locking screw, and the locking screw is adapted to the threaded grooves.

[0011] As a preferred embodiment of this utility model, the bottom of the support rod is detachably connected to an mounting plate, and all the legs are evenly fixed to the bottom of the mounting plate.

[0012] As a preferred embodiment of this utility model, all the outriggers include an inclined connecting rod and a fixing plate. The inclined connecting rod is detachably connected to the bottom of the support rod, and the fixing plate is fixedly connected to the end of the inclined connecting rod away from the support rod. The fixing plate has a through hole, and a bolt is inserted into the through hole.

[0013] As a preferred embodiment of this utility model, a positioning protrusion is fixedly connected to the outer wall of the support rod.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This invention connects a foam floating structure to a frame, allowing the foam board to rise and fall with the waves at different times. As the foam board floats on the water surface, it causes the frame and its internal camera device to float as well. This allows the camera device to continuously capture the water flow at the water's surface. This enables researchers to record the dynamic changes in the water surface when studying the hydrodynamic phenomena of floating bodies under wave action, aiding in the analysis of wave propagation and water flow patterns. For research on marine floating structures, it can record the movement of the floating body on the water surface, such as the swaying of buoys and the displacement of floating platforms, providing intuitive video data for related research.

[0016] 2. This utility model fixes the height of the movable cylinder by rotating the locking screw, passing it through the fixing screw hole and screwing it into the corresponding thread groove. By adjusting the height of the movable cylinder, observations can be made at different positions above the water surface, at the water surface junction, and underwater.

[0017] 3. This utility model fixes the mounting plate to the bottom of the support rod, and then places the support leg on the bottom of the water and fixes it to the bottom of the water with bolts. The fixing method is simple and the operation is convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, this utility model provides a water flow observation device suitable for wave tests of marine floating structures, including a support rod 1, a movable cylinder 2 slidably connected to the support rod 1, multiple legs 3 evenly arranged at the bottom of the support rod 1, a limiting member 4 for limiting the height of the movable cylinder 2 on the outer wall of the support rod 1, a frame 5 at the top of the movable cylinder 2, a waterproof cover 6 inside the frame 5, a camera device 7 installed inside the waterproof cover 6, and foam floating structures 8 on both sides of the frame 5. The foam floating structure 8 includes a foam board 9 and a connecting rope 10, the foam board 9 is fixedly connected to the connecting rope 10, and the connecting rope 10 is fixedly connected to the side wall of the frame 5.

[0025] As the foam floating structure 8 rises and falls with the water surface, the frame 5 and the camera device 7 inside it float accordingly.

[0026] In use, the support leg 3 is fixed to the bottom of the water, and the foam board 9 is connected together by multiple connecting ropes 10 to form multiple foam floating structures 8. The number of foam floating structures 8 is set to multiple, and the side of two adjacent foam floating structures 8 away from the frame 5 is connected by connecting ropes 10. Foam float structures 8 are installed on both sides of frame 5, and their number is selected according to specific circumstances. The foam float structures 8 on both sides of frame 5 are fixedly connected to frame 5 by connecting ropes 10. Subsequently, when observing the water flow on the water surface, the limiting piece 4 is released from the support rod 1. By connecting the foam float structures 8 to frame 5, the foam board 9 can rise and fall with the waves at different times. When the foam board 9 floats with the water surface, it can drive frame 5 and the camera device 7 inside to float as well. This allows the camera device 7 to rise and fall with the water surface, constantly capturing the water flow at the water surface interface. This allows researchers to record the dynamic changes of the water surface when studying the hydrodynamic phenomena of floats under the action of waves, assisting researchers in analyzing wave propagation, water flow morphology, etc. For the study of marine float structures, it can record the movement of floats on the water surface, such as the swing of buoys and the displacement of floating platforms, providing intuitive image data for related research. To facilitate the filming of the camera device 7, the waterproof cover 6 is made of transparent PVC material.

[0027] Furthermore, a water depth gauge 11 is provided on the outer wall of the support rod 1, and the surface of the water depth gauge 11 is coated with a waterproof coating.

[0028] The limiting component 4 includes a locking screw 12. A fixing screw hole is provided on the outer wall of the movable cylinder 2. The locking screw 12 is threaded into the inside of the fixing screw hole. Multiple threaded grooves 13 are evenly provided along the length direction on the side of the outer wall of the support rod 1 near the locking screw 12. The locking screw 12 is adapted to the threaded grooves 13.

[0029] If it is necessary to observe the water flow above or below the water surface, the movable cylinder 2 can be slid up and down to adjust its height. Then, by rotating the locking screw 12, it can be passed through the fixing screw hole and screwed into the corresponding threaded groove 13, thereby fixing the height of the movable cylinder 2. By adjusting the height of the movable cylinder 2, observations can be made at different positions above the water surface, at the water surface junction, and underwater.

[0030] It is worth noting that a positioning protrusion 19 is fixedly connected to the outer wall of the support rod 1. By setting the positioning protrusion 19 on the outer wall of the bottom end of the support rod 1, the lowest point of the sliding position of the movable cylinder 2 is located, so as to prevent the movable cylinder 2 from sliding and hitting the support leg 3 as the water level drops.

[0031] The bottom of the support rod 1 is detachably connected to the mounting plate 14, and all the support legs 3 are evenly fixed to the bottom of the mounting plate 14.

[0032] All outriggers 3 include an inclined connecting rod 15 and a fixing plate 16. The inclined connecting rod 15 is detachably connected to the bottom of the support rod 1, and the fixing plate 16 is fixedly connected to the end of the inclined connecting rod 15 away from the support rod 1. The fixing plate 16 has a through hole 17, and a bolt 18 is inserted into the through hole 17. To facilitate the installation of multiple outriggers 3, the positions of all outriggers 3 are fixed by a mounting plate 14. During installation, the mounting plate 14 is fixedly connected to the bottom of the support rod 1, and then the outriggers 3 are placed on the bottom of the water and fixed to the bottom surface by bolts 18. The fixing method is simple and convenient to operate.

[0033] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
