Description

Technical Field

[0001] The utility model belongs to the technical field of ocean observation equipment, and in particular relates to a portable drifting buoy used for collecting environmental parameters in waters such as nearshore and shallow seas. Background Art

[0002] With the continuous advancement of marine development and utilization, marine environmental monitoring plays an increasingly important role in marine scientific research, fishery resource management, coastal engineering construction, ecological environmental protection, and emergency response to sudden pollution accidents. As a flexible and efficient marine monitoring platform, drifting buoys can drift with ocean currents and tides to obtain dynamic environmental data in a wide range of areas, and have gradually become an important part of the marine observation system. Especially in nearshore and shallow sea areas, these areas have shallow water depths, frequent changes in flow velocity, and complex terrain, which put forward more stringent requirements on the stability, adaptability, and ease of operation of drifting buoys.

[0003] At present, the widely used drifting buoys are mostly large-scale structural designs, usually made of fiberglass or plastic materials into spherical or cylindrical floats, with long anchor chains, water sails and multiple sections of external cables to maintain hydrodynamic balance and stable drift direction. This type of system has certain stability and reliability in the open ocean or deep sea environment, but it exposes many problems in nearshore or shallow sea areas. First, due to the large size and heavy weight of the equipment, its deployment and recovery usually require the help of professional ships and technicians, the operation process is complicated and the efficiency is low, which seriously restricts the maneuverability of the equipment. Second, the underwater structure of the drifting buoy usually includes multiple components such as anchor chains, water sails, sensor cables, etc. In shallow water areas, it is more susceptible to entanglement with water plants, floating objects, and fishing gear, resulting in sensor signal interruption, data loss, and even equipment damage, and the operating failure rate is significantly increased. In addition, the existing drifting buoy system generally has deficiencies in functional integration. Some designs rely on multiple independent subsystems to complete functions such as power supply, communication, and data acquisition, which not only increases the complexity and volume of the system, but also increases energy consumption and maintenance costs. Especially in nearshore areas where monitoring tasks are carried out at a high frequency and in multiple batches, traditional large-scale buoy equipment is particularly inconvenient in terms of rapid deployment and multi-point deployment, and cannot meet the actual application needs of flexibility, efficiency and low cost.

[0004] As marine environmental monitoring becomes increasingly sophisticated and diversified, there is an urgent need for a portable drifting buoy device that is compact, easy to operate, more functionally integrated, and suitable for the complex environment of nearshore and shallow waters to meet the requirements of multiple uses in daily monitoring, emergency response, scientific observation and other scenarios. Utility Model Content

[0006] A portable drifting buoy comprises an annular float and a main control cabin arranged below the annular float, and a spoiler suspended below the annular float and located at the periphery of the main control cabin; a communication module, a wave sensor, a power module and a data acquisition module are integrated in the main control cabin, and a temperature-salinity-depth instrument is installed on the side or bottom of the outside of the main control cabin; the data acquisition module is used for processing and storing data collected by the wave sensor and the temperature-salinity-depth instrument, and the communication module is used for transmitting the collected data to a shore-based server or a mobile terminal.

[0007] Furthermore, the annular floating body is welded into a ring using stainless steel pipes, and its internal hollow structure forms a sealed buoyancy chamber, and its bottom surface is provided with a plurality of hanging points for carrying the underwater part of the buoy.

[0008] Furthermore, the spoiler adopts a single-piece cross-shaped or multi-piece design and is suspended on the periphery of the main control cabin by a short iron chain with adjustable length.

[0009] Furthermore, a data / charging interface is provided on the top of the main control cabin for reading or writing data and for periodically charging the power module.

[0010] Furthermore, a waterproof antenna is provided on the top of the main control cabin for use with the communication module.

[0011] Preferably, an expansion interface for accessing an expansion module is also reserved on the top of the main control cabin.

[0012] Preferably, the surface of the annular buoy is provided with an anti-corrosion coating.

[0013] Preferably, the outer shell of the main control cabin is made of stainless steel or corrosion-resistant alloy.

[0014] The utility model adopts an annular steel structure (relative to the traditional spherical fiberglass and plastic floats, it is stronger and easier to operate and recover), and arranges the underwater part as a cross spoiler to replace the traditional water sail. The power supply, communication and data acquisition functions are integrated in the main control cabin to reduce external cables and redundant components. This solution can effectively improve the stability and reliability of the drifting buoy in nearshore and shallow sea environments, and reduce the cost of deployment, recovery and maintenance.

The main control cabin 3 integrates a communication module 8, a wave sensor 9, a power module 10, and a data acquisition module 12, etc., and a temperature-salinity-depth meter 11 is installed on the side or bottom of the main control cabin 3 to ensure that the sensor can monitor the seawater parameters in real time.

[0021] The annular buoy 1 is made of a stainless steel pipe bent into a ring and welded into a circle, and its internal hollow structure forms a sealed buoyancy chamber; the surface of the buoy is treated with an anti-corrosion coating to improve corrosion resistance; the bottom of the buoy is connected to a short iron chain 2 through a welding hanging point, which is used to carry the underwater part of the buoy. The spoiler 4 is arranged vertically on the periphery of the main control cabin 3 through the short iron chain 2, and can be a cross-shaped or multi-piece design. By adjusting the length of the short iron chain 2, the stability requirements in different environments can be met.

The data acquisition module 12 is responsible for the centralized management and preliminary processing of the data collected by various sensors. The communication module 8 can transmit the collected data to the shore-based server or mobile terminal in combination with the waterproof antenna 5 set on the top of the main control cabin 3, supporting remote configuration and monitoring. The communication module 8 is used in conjunction with the waterproof antenna 5 to support multiple communication modes (such as 4G / 5G, Beidou / GPS) to meet the real-time data upload and positioning requirements of offshore or shallow sea environments.

[0023] After the above-mentioned drifting buoy is placed in the target waters, the annular float 1 provides the main buoyancy, and the spoiler 4 generates resistance under the action of the water flow, reducing the rotation and drift of the buoy, reducing the disturbance of wind and waves and ocean currents to the buoy, and realizing a relatively stable monitoring platform; the internal sensors of the main control cabin 3 obtain marine environmental data in real time, and the communication module 8 is responsible for the wireless transmission of data; when maintenance or recovery is required, it can be quickly recovered by small boats or manual methods, and batteries can be replaced, equipment can be checked, and data can be downloaded.

[0024] The utility model relies on a stainless steel annular float to provide buoyancy, and is connected to the underwater part by a short iron chain; the underwater part is provided with a main control cabin and a heightened spoiler at the center, thus constructing a drifting buoy system that is compact, sturdy, and easy to deploy and recover. The system does not require external cables, and the main control cabin integrates a communication module, a data acquisition module, a power module, and a wave sensor. A temperature, salinity, and depth meter can be carried externally, and a waterproof antenna is used to ensure data transmission in the marine environment.
