An isolated wave observation platform in the ocean

Abstract

The present application relates to the technical field of ocean observation, and discloses an ocean internal solitary wave observation platform, which comprises a bearing frame, an observation device and a buffer assembly. A plurality of vertically arranged and spaced floating bodies are installed on the bearing frame. Surface waves can pass between the plurality of dispersed floating bodies, effectively reducing the drop effect when the internal solitary wave passes through the bearing frame and the floating bodies, and ensuring the accuracy of the observation results. The spiral floating body reduces its contact area with the surface wave, improving the stability of the observation platform. The buffer assembly can absorb and filter the longitudinal and transverse wave oscillations of seawater, further eliminating the influence of residual fluctuations on the observation device. The buffer assembly is connected to the center of gravity of the bearing frame, i.e. the observation device is located below the center of gravity of the bearing frame, so that the buoyancy and gravity of the entire observation platform are on the same straight line, which can further improve the stability of the observation device, thereby improving the observation efficiency and the accuracy of the observation results, and providing effective protection for underwater activities and marine engineering.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean observation, and in particular to an ocean internal solitary wave observation platform. BACKGROUND

[0002] Internal wave is an important sea water movement, which transmits the energy of the upper layer of the sea to the deep layer, and brings the cold sea water in the deep layer to the shallow layer together with nutrients, so as to promote the breeding of organisms. The internal solitary wave is a special wave in the internal wave, which has the shape and nature of the solitary wave. It generally appears near the depth of the thermocline of the sea water (i.e. the depth near the thermocline of the sea area), and is a strong nonlinear internal wave with large amplitude (generally more than tens of meters), strong flow speed and specific direction of propagation, which is generated by strong tidal current when passing through the steep seamount.

[0003] At present, the internal solitary wave has become the most influential mesoscale ocean phenomenon for offshore oil development. Through accurate and systematic observation of the internal solitary wave, effective protection can be provided for offshore oil development engineering and underwater construction. In the prior art, the observation of the internal solitary wave mainly adopts two ways of a subsurface buoy and a surface buoy. The whole buoy body of the subsurface buoy is located below the sea surface, and the main observation buoy body is located near the main thermocline. Due to the large amplitude characteristics of the internal solitary wave, the observation buoy body will have a significant drop effect when the internal solitary wave passes through, which not only leads to the lack of observation range, but also easily causes the speed and attitude of the observation instrument itself to change complexly, resulting in the distortion of the measured data of the internal solitary wave, especially the vertical velocity observation of the internal solitary wave, which will miss the key characteristic information.

[0004] The surface buoy floats on the sea surface and is directly affected by the surface wave. The surface wave is usually not a single sine wave, but a complex and rapidly changing integral wave affected by various factors. The fluctuation of the surface wave interacts with the buoy, so that the observation instrument installed on the buoy also has a particularly complex motion, which is difficult to separate effectively in the later stage, resulting in inaccurate internal solitary wave velocity measured by the observation instrument.

[0005] Therefore, there is an urgent need for an ocean internal solitary wave observation platform to solve the above problems. SUMMARY

[0006] Based on the above problems, the purpose of the present application is to provide an ocean internal solitary wave observation platform, which can accurately measure the internal solitary wave of the ocean and provide effective protection for underwater activities and marine engineering.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0037] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixed connection, or it can be detachable connection; it can be mechanical connection, or it can be electrical connection; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] As shown in Figures 1 to 5 The present embodiment provides an internal solitary wave observation platform for ocean, which can be applied to internal solitary wave observation of underwater engineering such as oil development. The internal solitary wave observation platform for ocean comprises a bearing frame 1, a plurality of floating bodies 2, an observation device 3 and a buffer assembly 4.

[0039] The plurality of floating bodies 2 are distributed at intervals on the bearing frame 1, and each floating body 2 is vertically mounted on the bearing frame 1. Each floating body 2 is in a spiral shape. The observation device 3 is used for observing the internal solitary wave of the ocean. One end of the buffer assembly 4 is connected to the center of gravity of the bearing frame 1 and located on the side away from the plurality of floating bodies 2, and the other end of the buffer assembly 4 is connected to the observation device 3. The buffer assembly 4 is configured to be able to absorb and filter longitudinal and transverse wave oscillations of the sea.

[0040] The observation of internal solitary wave of ocean has three main points. The first is dynamic observation, mainly aiming at the divergence and convergence driven by internal solitary wave propagation; the second is kinematic observation, mainly aiming at the kinematic observation of the structure of internal solitary wave structure monomer in a period; the third is hydrological observation, mainly aiming at the distribution change of water temperature, salinity and density caused by internal solitary wave.

[0041] The ocean internal solitary wave observation platform provided by the embodiment is mainly used to solve the problem that the observation platform is unstable and affects the observation of the dynamics and kinematics of the ocean internal solitary wave. Since the plurality of vertically arranged floating bodies 2 are dispersedly fixed on the bearing frame 1 (i.e., the floating bodies 2 are vertically fixed on the bearing frame 1), and each floating body 2 is helical, the surface wave can pass through the plurality of dispersed floating bodies 2, effectively reducing the drop effect of the internal solitary wave when passing through the bearing frame 1 and the floating bodies 2, avoiding the complex motion of the observation equipment 3 itself, and thus ensuring the accuracy of the observation results. The vertically arranged helical floating bodies 2 reduce the direct contact area between the floating bodies 2 and the surface wave of the sea, thereby greatly improving the stability of the observation platform and further reducing the influence of the surface wave fluctuation on the observation results of the observation equipment 3. In addition, since the observation equipment 3 and the bearing frame 1 are connected through the buffer assembly 4, the buffer assembly 4 can absorb and filter the longitudinal and transverse wave oscillation of the seawater, thereby further eliminating the influence of the residual wave fluctuation of the sea wave on the observation equipment 3. The buffer assembly 4 is connected to the center of gravity of the bearing frame 1, i.e., the observation equipment 3 is located below the center of gravity of the bearing frame 1, so that the buoyancy and gravity of the entire observation platform are on the same straight line, which can more effectively improve the stability of the observation equipment 3, and thus improve the observation efficiency and the accuracy of the observation results. That is, the ocean internal solitary wave observation platform can not only overcome the influence of the drop effect of the internal solitary wave on the floating bodies 2 on the observation results, but also effectively reduce the oscillation influence of the surface wave on the floating bodies 2, so that the observation equipment 3 can accurately obtain the kinematic structure within the period of the ocean internal solitary wave, thereby providing effective protection for underwater activities and marine engineering.

[0042] Optionally, referring to Figure 1 and Figure 2 , the bearing frame 1 includes a frame ring 11, a plurality of first rods 12 and a plurality of second rods 13, the plurality of first rods 12 and the plurality of second rods 13 are cross arranged in the frame ring 11 and connected with the frame ring 11. The plurality of first rods 12 and the plurality of second rods 13 increase the structural strength of the entire bearing frame 1, and at the same time, the first rod 12 (the second rod 13) can provide a mounting base for the connection of the buffer assembly 4 and the bearing frame 1. In the embodiment, the plurality of floating bodies 2 are fixed on the frame ring 11 in the circumferential direction to dispersely arrange the plurality of floating bodies 2, and the surface wave can pass through the plurality of floating bodies 2, thereby effectively reducing the drop effect of the internal solitary wave when passing through the bearing frame 1 and the floating bodies 2.

[0043] Optionally, referring to Figure 2 , the frame ring 11 includes a first ring part 111 and a second ring part 112 which are symmetrically arranged, and the outer contours of the first ring part 111 and the second ring part 112 are in the shape of a Fibonacci spiral. The curved frame ring 11 can effectively suppress the drop effect of the internal solitary wave and improve the stability of the entire observation platform in water.

[0044] Specifically, referring to Figure 3 , the first circle part 111 and the second circle part 112 have the same structure, and the first circle part 111 is taken as an example, the first circle part 111 includes a first circular arc part 1111, a second circular arc part 1112, a third circular arc part 1113 and a fourth circular arc part 1114 which are sequentially connected and have radii that increase sequentially, the radius of the first circular arc part 1111 is a, the radius of the second circular arc part 1112 is b, the radius of the third circular arc part 1113 is a+b, and the radius of the fourth circular arc part 1114 is a+2b, wherein a / b=b / (a+b)=(a+b) / (a+2b)=φ, φ is the equal ratio of the first circle part 111. That is, the first circle part 111 is formed by adopting the equal ratio rule, and referring to the direction in Figure 3 , the first circular arc part 1111, the second circular arc part 1112, the third circular arc part 1113 and the fourth circular arc part 1114 are all 1 / 4 circles and sequentially rotate counterclockwise. The ratio of the radii of the first circular arc part 1111 and the second circular arc part 1112 is a / b=φ, the ratio of the radii of the second circular arc part 1112 and the third circular arc part 1113 is b / (a+b)=φ, and the ratio of the radii of the third circular arc part 1113 and the fourth circular arc part 1114 is (a+b) / (a+2b)=φ. The first circle part 111 and the second circle part 112 are spliced to form the entire bearing frame 1 with the inner tangent of the spiral line as the axis of symmetry.

[0045] Preferably, in the embodiment, the equal ratio φ=(√5-1) / 2. Through a series of offshore experiments on bearing frames 1 with different φ values, it is found that when φ=(√5-1) / 2, the coordination of each ratio is optimal, and the effect of suppressing the inner solitary wave drop effect and filtering the influence of surface waves is optimal. Therefore, taking φ=(√5-1) / 2 as the equal ratio value can make the entire observation platform provide a stable foundation for the observation equipment 3 and ensure the accuracy of the observation results.

[0046] In the embodiment, the observation equipment 3 is designed to be at the center of gravity of the bearing frame 1 of the symmetric Fibonacci spiral, so that the observation equipment 3 matches the center of gravity and the center of buoyancy of the sea surface float 2 underwater, thereby making the entire observation platform more stable and the observation results more accurate.

[0047] Optionally, referring to Figure 1 and Figure 4The buffer assembly 4 comprises a first connecting piece 41, a second connecting piece 42 and a connecting ring 43. The first connecting piece 41 is provided with a first through hole 411, the second connecting piece 42 is provided with a second through hole 421, and the connecting ring 43 is movably arranged in the first through hole 411 and the second through hole 421 to movably connect the first connecting piece 41 and the second connecting piece 42. The design that the first connecting piece 41 and the second connecting piece 42 are movably connected through the connecting ring 43 leaves a redundant space between each two adjacent ones of the first connecting piece 41, the second connecting piece 42 and the connecting ring 43, which can effectively filter the longitudinal oscillation and the transverse oscillation of the surface wave, thereby improving the stability and observation accuracy of the observation device 3.

[0048] Preferably, the first connecting piece 41, the second connecting piece 42 and the connecting ring 43 are all made of a corrosion-resistant material, which is preferably titanium. The titanium material has strong seawater corrosion resistance, high strength, low density and no magnetism, and thus does not affect the observation device 3 and the bearing frame 1, thereby ensuring that the observation device 3 can run smoothly.

[0049] Further, referring to Figure 5 , the connecting ring 43 is provided with a cavity, and a plurality of balls 431 are arranged in the cavity. The plurality of balls 431 in the connecting ring 43 can reduce the resistance between the connecting ring 43 and the water, thereby effectively filtering the transverse oscillation and longitudinal oscillation of the seawater.

[0050] Optionally, referring to Figure 4 and Figure 5 , the buffer assembly 4 further comprises a universal connecting piece 44, one end of the universal connecting piece 44 is connected to the second connecting piece 42, and the other end of the universal connecting piece 44 is connected to the observation device 3. The universal connecting piece 44 can rotate in any direction to further filter the fluctuation in any direction, thereby further improving the stability and observation accuracy of the observation device 3.

[0051] Optionally, referring to Figure 1 and Figure 4 , the ocean internal solitary wave observation platform further comprises a battery unit 5, which is arranged at the center of gravity of the bearing frame 1 and is electrically connected to the observation device 3, for supplying power to the observation device 3 to ensure that the observation device 3 can operate normally. Further, the observation device 3 comprises an information storage unit for storing the internal solitary wave information obtained by observation and collection. An antenna 6 is arranged above the battery unit 5, and the antenna 6 is used for receiving or transmitting signals to facilitate grasping the real-time position and observation situation of the observation platform.

[0052] Optionally, an acceleration sensor is arranged on the observation device 3, and the acceleration sensor is used to measure the longitudinal displacement of the observation device 3. Since the surface wave and the internal solitary wave with large fluctuation amplitude can still have a great influence on the observation device 3, the longitudinal shaking of the observation device 3 can be accurately recorded by arranging the acceleration sensor, so as to facilitate the noise removal and error removal when the data is processed later, and to prevent the observation result from being inaccurate. The acceleration sensor is preferably a high-precision sensor with small noise and high observation accuracy.

[0053] It should be noted that the above only describes the preferred embodiments of the present application and the technical principles applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the protection scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
