Description

Technical Field

[0001] This utility model relates to the field of marine observation technology, and more specifically, to an automatic anti-capsulation system. Furthermore, this utility model also relates to a floating wind-measuring lidar including the aforementioned automatic anti-capsulation system. Background Technology

[0002] In the field of marine observation, acquiring data on wind fields, hydrology, and meteorology in various sea areas is particularly important. Buoys, as independently operating carriers at sea, can be flexibly deployed in different sea areas. A buoy platform refers to a device carrier platform deployed in the ocean, equipped with self-powered systems such as solar and wind power, capable of carrying various meteorological and hydrological sensors for autonomous operation, ranging in size from 1m to 10m, and mostly secured with anchor chains. Floating wind-measuring lidar based on buoys enables long-term observation of wind fields in different sea areas, offering advantages such as unmanned operation and all-weather observation. Simultaneously, the system can integrate multiple hydrological observation instruments to achieve three-dimensional monitoring of marine environmental parameters, playing a vital role in multiple fields such as marine wind resource exploration, marine meteorological monitoring, and air-sea boundary layer observation.

[0003] However, the weather at sea is unpredictable. Typhoons, cold waves, cyclones, and other weather phenomena can cause varying degrees of damage to floating lidar systems. Therefore, the environmental adaptability of the buoy platform is of paramount importance in all research and development processes. The most serious and catastrophic damage is buoy capsizing, which can result in system damage or even buoy sinking.

[0004] Existing anti-capsizing devices generally fall into two categories. One type uses an airbag stored in a cavity that extends through a connecting plate. This method requires storing the airbag and connecting plate in the cabin, occupying significant cabin space. Furthermore, it can only be released from the sides of the hull, failing to provide comprehensive protection. The extension mechanism is also complex and carries certain risks in its implementation. The other type uses a circular array sensor combined with a gravity ball for sensing. Once the array sensor detects the gravity ball's position, the system releases the anti-capsizing device at the corresponding location, stabilizing the offshore wind power platform. However, this gravity ball and array sensor method suffers from a slow dynamic response to the platform's attitude, and if it fails to respond promptly to the platform's dynamic attitude, it also carries the risk of capsizing.

[0005] In conclusion, how to prevent buoy platforms from capsizing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an automatic anti-overturning system, which sends signals to the control system through an attitude monitoring component, and the control system controls the anti-overturning component to extend or retract according to the received signals, so as to adjust the attitude of the buoyancy chamber and prevent overturning.

[0007] Another objective of this invention is to provide a floating wind-measuring lidar that includes an automatic anti-tipping system.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An automatic anti-rollover system includes:

[0010] Buoyancy chamber, used to float on the surface of water;

[0011] An anti-overturning assembly is retractably disposed in the buoyancy chamber, and the anti-overturning assembly is used to prevent the buoyancy chamber from overturning when it is extended;

[0012] A control system is signal-connected to the anti-rollover assembly and used to control the extension or retraction of the anti-rollover assembly;

[0013] An attitude monitoring component is installed in the buoyancy chamber and connected to the control system via a signal. The attitude monitoring component is used to detect the attitude of the buoyancy chamber and send a signal to the control system based on the attitude of the buoyancy chamber.

[0014] Preferably, the anti-overturning assembly includes an anti-overturning float and a hydraulic support rod. The anti-overturning float is rotatably connected to the side wall of the buoyancy chamber, and the two ends of the hydraulic support rod are respectively connected to the buoyancy chamber and the anti-overturning float.

[0015] Preferably, the number of anti-overturning floats is the same as the number of hydraulic support rods, and multiple anti-overturning floats are provided, with the multiple anti-overturning floats evenly distributed on the side wall of the buoyancy chamber.

[0016] Preferably, the anti-overturning assembly further includes a sensor disposed in the buoyancy chamber, the sensor being used to detect the angle between the anti-overturning float and the buoyancy chamber, and the sensor being signal-connected to the control system.

[0017] Preferably, the anti-overturning float has a hollow structure.

[0018] Preferably, it also includes a buoy platform, which is disposed on the upper surface of the buoyancy chamber. The buoy platform has a plate-like structure, and the attitude monitoring component is disposed on the surface of the buoy platform.

[0019] Preferably, the attitude monitoring component includes a lidar host module, which is mounted on a base. The base is fixed to the surface of the buoy platform by multiple support columns, and the base is arranged parallel to the buoy platform.

[0020] Preferably, the system also includes a solar panel, wherein multiple solar panels are provided and each solar panel is fixed to the support column. The solar panels are electrically connected to the anti-tipping component, the control system, and the attitude monitoring component and are used to supply power to them.

[0021] Preferably, the surfaces of the buoyancy chamber, the anti-overturning component, and the attitude monitoring component are all provided with an anti-corrosion coating.

[0022] A floating wind-measuring lidar includes an automatic anti-tipping system, wherein the automatic anti-tipping system is any of the above-mentioned automatic anti-tipping systems.

[0023] This utility model provides an automatic anti-capsizing system. The anti-capsizing component of this system is retractably mounted on the buoyancy chamber. An attitude monitoring component detects the attitude of the buoyancy chamber and sends a signal to the control system based on this attitude. Upon receiving the signal, the control system extends or retracts the anti-capsizing component. Specifically, when the buoyancy chamber's attitude is unstable and about to capsize, the attitude monitoring component detects the buoyancy chamber's attitude and sends a signal to the control system. The control system then extends the anti-capsizing component to increase the area of ​​the buoyancy chamber floating on the water surface, preventing capsizing. When the buoyancy chamber's attitude tends to stabilize, the attitude monitoring component detects its attitude and sends a signal to the control system, which then retracts the anti-capsizing component. This process improves the stability of the buoyancy chamber, thereby enhancing its wind resistance and solving the problem of reduced maritime survivability caused by the small size design of small buoys designed for easy deployment and reduced collisions.

[0030] 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.

[0031] The core of this invention is to provide an automatic anti-tipping system, which improves platform stability and reduces the probability of tipping over.

[0032] Another core aspect of this invention is to provide a floating wind-measuring lidar that includes the aforementioned automatic anti-tipping system.

[0033] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to 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 of this application.

[0034] This application provides an automatic anti-tipping system, comprising: a buoyancy chamber 1, an anti-tipping component 2, and a control system and attitude monitoring component 3;

[0035] Among them, buoyancy chamber 1 is used to float on the water surface;

[0036] The anti-overturning component 2 is retractably installed in the buoyancy chamber 1. When the anti-overturning component 2 is extended, it is used to prevent the buoyancy chamber 1 from overturning.

[0037] The control system is signal-connected to the anti-rollover assembly 2 and is used to control the extension or retraction of the anti-rollover assembly 2;

[0038] The attitude monitoring component 3 is located in the buoyancy chamber 1 and is connected to the control system signal. The attitude monitoring component 3 is used to detect the attitude of the buoyancy chamber 1 and send signals to the control system according to the attitude of the buoyancy chamber 1.

[0039] For details, please refer to the appendix. Figure 1The buoyancy chamber 1, serving as the base of the small buoy, generally floats on the water surface. An anti-capsulation component 2 is installed on the buoyancy chamber 1. This component is retractable. When the anti-capsulation component 2 extends from the buoyancy chamber 1, it increases the volume of the buoyancy chamber 1 while maintaining its total weight. According to the density formula ρ=m / V, where m is considered the mass of the small buoy and V is considered its volume, when the anti-capsulation component 2 extends, m remains constant while V increases, thus decreasing ρ and maintaining the small buoy's floating state on the water surface. Furthermore, when the anti-capsulation component 2 extends from the buoyancy chamber 1, the contact area between the combined buoyancy chamber 1 and the water surface increases, improving the stability of the buoy platform and thus enhancing its wind resistance. This solves the problem of reduced maritime survivability caused by the small size design of small buoys for easy deployment and reduced collisions.

[0040] Based on the above embodiments, the anti-overturning assembly 2 includes an anti-overturning float 201 and a hydraulic support rod 202. The anti-overturning float 201 is rotatably connected to the side wall of the buoyancy chamber 1, and the two ends of the hydraulic support rod 202 are respectively connected to the buoyancy chamber 1 and the anti-overturning float 201.

[0041] For details, please refer to the appendix. Figure 2 The anti-overturning float 201 is normally an assembly attached to the side wall of the buoyancy chamber 1. At this time, the anti-overturning float 201 is a plate-shaped structure arranged vertically, and its length should be greater than its thickness to ensure that the area of ​​the anti-overturning assembly 2 on the water surface should be greater than its area in the retracted state when the anti-overturning float 201 is extended. In other words, it can ensure that the anti-overturning float 201 can improve stability when extended. In addition, the upper end of the anti-overturning float 201 is rotatably connected to the buoyancy chamber 1, and the middle or lower end of the anti-overturning float 201 is connected by a hydraulic support rod 202. The hydraulic support rod 202 can be electrically assisted driven, that is, integrated electric pump or solenoid valve, and the hydraulic pressure is controlled by electricity. The electric pump or solenoid valve is connected to the control system, and the state of the anti-overturning float 201 is regulated by the control system to improve the automation level of the structure.

[0042] Alternatively, the lower end of the anti-overturning float 201 can be rotatably connected to the buoyancy chamber 1 as another embodiment.

[0043] Based on the above embodiments, the number of anti-overturning floats 201 and hydraulic support rods 202 is the same and there are multiple anti-overturning floats 201 evenly distributed on the side wall of the buoyancy chamber 1.

[0044] Specifically, the number of anti-overturning floats 201 and hydraulic support rods 202 are the same and they are installed in a one-to-one correspondence. Please refer to the appendix. Figure 2The number of anti-overturning floats 201 is preferably six, and they are evenly distributed on the side of the buoyancy chamber 1. The surface of the anti-overturning float 201 facing away from the buoyancy chamber 1 is an arc-shaped surface. When the anti-overturning float 201 is retracted, the six anti-overturning floats 201 and the buoyancy chamber 1 can form a cylindrical structure. The anti-overturning floats 201 are installed in a circumferential array, covering all directions of the side wall of the buoyancy chamber 1, which can achieve all-round protection for the buoy platform.

[0045] Optionally, the number of anti-overturning floats 201 can be seven or even more, but they still need to be installed in a circumferential array.

[0046] Based on the above embodiments, the anti-overturning assembly 2 also includes a sensor 203, which is located in the buoyancy chamber 1. The sensor 203 is used to detect the angle between the anti-overturning float 201 and the buoyancy chamber 1, and the sensor 203 is connected to the control system signal.

[0047] Specifically, sensor 203 can monitor the release or retraction status of anti-overturning float 201. After the lidar host module 5 analyzes the stable attitude of the buoy platform 4, it issues a float retraction command, and the hydraulic support rod 202 performs a retraction action to retract the anti-overturning float 201.

[0048] Based on the above embodiments, the anti-overturning float 201 has a hollow structure.

[0049] Specifically, the anti-overturning float 201 should be a plate-shaped component with low density, preferably a hollow shell. The material of the anti-overturning float 201 is preferably a lightweight material, such as plastic, which is low in cost and ensures that the volume and weight are appropriate.

[0050] In some embodiments, the system further includes a buoy platform 4, which is disposed on the upper surface of the buoyancy chamber 1. The buoy platform 4 has a plate-like structure, and the attitude monitoring component 3 is disposed on the surface of the buoy platform 4.

[0051] For details, please refer to the appendix. Figure 3 A buoy platform 4 is mounted on the upper surface of the buoy chamber 1. The upper surface of the buoy platform 4 should be a flat plate. The attitude monitoring component 3 is mounted on the surface of the buoy platform. In this embodiment, the middle of the buoy platform 4 is taken as the origin of the coordinate system, and a buoy platform coordinate system, namely the X0Y0Z0 coordinate system, is established. Based on this, a lidar coordinate system, namely the X1Y1Z1 coordinate system, is established, as detailed in the attached figure. Figure 3 As shown, the establishment of the buoy platform coordinate system and the lidar coordinate system can work with the attitude monitoring component 3 to detect the attitude of the buoy platform 4.

[0052] Based on the above embodiments, the attitude monitoring component 3 includes a lidar host module 5, which is located on the base. The base is fixed to the surface of the buoy platform 4 by multiple support columns, and the base is arranged parallel to the buoy platform 4.

[0053] Specifically, the lidar main module 5 is isolated from the buoy platform 4 by a support column and base, and the base is parallel to the buoy platform 4. The lidar main module 5 is installed on the central axis of the buoy platform 4. The height difference H between the radar X1 axis and the buoy platform 4 X0 axis is significant. The attitude information of the lidar main module 5, such as heading angle H1, pitch angle P1, and roll angle R1, needs to be calculated based on the correlation between the radar coordinate system and the buoy platform coordinate system. Based on the calculation results, the radar will analyze the current attitude of the buoy platform and determine whether the tilt angle of a certain azimuth of the buoy platform 4 in the current state exceeds the threshold. If it exceeds the threshold, the anti-overturning component 2 will be activated.

[0054] Based on the above embodiments, a solar panel 6 is also included. Multiple solar panels 6 are provided, and all multiple solar panels 6 are fixed to the support column. The solar panels 6 are electrically connected to the anti-tipping component 2, the control system, and the attitude monitoring component 3 and are used to supply power to them.

[0055] Specifically, solar panels 6 are installed on the outer perimeter of the support column. The solar panels 6 generate photovoltaic power and supply power to the anti-tipping component 2, the control system, and the attitude monitoring component to achieve independent and autonomous operation at sea.

[0056] Optionally, a backup battery can be installed in the buoyancy chamber 1. This backup battery can power the anti-tipping component 2, the control system, and the attitude monitoring component on cloudy or rainy days. The backup battery can also be connected to the solar panel 6. When there is sufficient sunlight, the photovoltaic power generation can not only provide power for autonomous operation, but also charge the backup battery.

[0057] Based on the above embodiments, the surfaces of the buoyancy chamber 1, the anti-overturning component 2, and the attitude monitoring component 3 are all provided with anti-corrosion coatings.

[0058] Specifically, floating buoy platforms are exposed to harsh environments of high salinity, high humidity, strong ultraviolet radiation, and marine organism attachment for extended periods. Therefore, surface corrosion protection requires a comprehensive approach combining materials science, coating technology, and engineering design. Examples include: epoxy resin-based coatings, which offer excellent adhesion, chemical resistance, and impermeability, and are often used as a base layer for corrosion protection; polyurethane / fluorocarbon topcoats, which provide UV resistance, salt spray resistance, and impact protection; and fluorocarbon coatings (such as PVDF), which offer exceptionally long weather resistance (over 20 years); and antifouling coatings, containing cuprous oxide or environmentally friendly antifouling agents (such as silicone-based materials), to prevent the attachment of marine organisms such as barnacles and algae.

[0059] In addition to the aforementioned automatic anti-tipping system, this utility model also provides a floating wind-measuring lidar that includes the automatic anti-tipping system disclosed in the above embodiments. The structure of the other parts of this floating wind-measuring lidar can be found in the prior art, and will not be described in detail here.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0061] The above provides a detailed description of the automatic anti-tipping system and floating wind-measuring lidar provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
