Description

Technical Field

[0001] This utility model relates to a tide level monitoring system and a wave observation buoy system integrating a tide level monitoring station. It is applicable to the field of seabed monitoring instrument installation technology. Background Technology

[0002] With the vigorous advancement of offshore wind farm projects, marine hydrological surveys, as a crucial link in the early planning and design phase, face severe challenges, especially in acquiring annual tide data. Due to the complexity of the marine environment, its spatiotemporal variability, and the unique conditions of specific sea areas, obtaining comprehensive, accurate, and representative annual tide data is indeed quite difficult. Tide observation equipment needs to operate stably in designated locations for extended periods, involving a series of complex tasks such as equipment selection, deployment, calibration, maintenance, and retrieval. The highly corrosive marine environment and strong currents place extremely high demands on the durability, stability, and biofouling resistance of the equipment. Furthermore, regular equipment maintenance and calibration often require specialized vessels and personnel for offshore operations, which are costly and subject to weather windows.

[0003] The utility model patent with authorization announcement number CN208125134U and application date of April 13, 2018, relates to an installation technology for seabed detection instruments. It discloses an anti-trawling and sinking tide level observation platform, which solves the problem that existing tide level instruments are easily dragged away by trawl nets, resulting in the loss of the tide level instruments. The anti-trawling and sinking tide level observation platform includes a counterweight platform. The counterweight platform is heavy enough to partially or completely sink into the seabed silt. The counterweight platform is equipped with mounting components for installing the tide level instrument and protective components set on the counterweight platform outside the tide level instrument to prevent the trawl net from scratching the tide level instrument. It has the advantages of reducing the probability of tide level instrument loss and saving resources.

[0004] The utility model patent with authorization announcement number CN212721625U and application date of September 4, 2020, relates to a device for placing a temporary tide gauge station. The purpose of this utility model is to provide a device with a simple structure, easy manufacturing, and low cost for placing a temporary tide gauge station, enabling the station to be placed in various coastal environments and preventing it from swaying due to water flow impact. The technical solution is as follows: A device for placing a temporary tide gauge station, characterized by: a protective cylinder with a bottom plate, the bottom plate having drainage holes, and several exchange holes I evenly distributed on the wall of the protective cylinder; an installation cylinder inside the protective cylinder, the wall of which has several exchange holes II, with a certain gap between the outer wall of the installation cylinder and the inner wall of the protective cylinder; a fixing mechanism at the lower end of the protective cylinder for fixing the device to the seabed, the tide gauge being vertically placed inside the installation cylinder and fixed to a connecting rod at the top with ropes. This utility model is applicable to the placement of temporary tide gauge stations near the coast of the ocean.

[0005] Currently, while the methods and devices used for deploying tide gauge stations can reduce the risk of these stations being towed away by trawlers in nearshore waters to some extent, they cannot meet the needs for effective observation in deep-sea areas with depths exceeding 50 meters. In these deep-sea areas, the seabed topography is more complex and varied. On the one hand, it is necessary to consider how to prevent the tide gauge stations from being damaged by trawlers, ensuring the safety of the measuring instruments; on the other hand, it is also necessary to avoid the stations shaking due to currents, which could affect the accuracy of the observation data. Furthermore, the ease of instrument retrieval in complex environments and the economic costs of deploying and maintaining the tide gauge stations must also be considered. Utility Model Content

[0006] The technical problem to be solved by this utility model is: to provide a tide level station system and a wave observation buoy system integrating a tide level station, in view of the above-mentioned problems.

[0007] The technical solution adopted in this utility model is: a tide level monitoring system, characterized in that it includes:

[0008] The main anchor can use its own weight to embed itself partially or completely into the seabed silt.

[0009] Anchor chain, attached to the main anchor;

[0010] A tide gauge is installed on the main anchor.

[0011] A sleeve is installed on the main anchor, and the tide gauge is fixed inside the sleeve.

[0012] A secondary anchor is connected to the anchor chain.

[0013] The secondary anchor is attached to the anchor chain at a distance of 3 to 5 meters from the main anchor.

[0014] A wave observation buoy system integrating a tide gauge station, characterized in that it includes:

[0015] Main body of the wave observation buoy;

[0016] The main anchor can use its own weight to embed itself partially or completely into the seabed silt.

[0017] An anchor chain connects the main anchor to the main body of the wave observation buoy;

[0018] A tide gauge is installed on the main anchor.

[0019] A sleeve is installed on the main anchor, and the tide gauge is fixed inside the sleeve.

[0020] A secondary anchor is connected to the anchor chain.

[0021] The secondary anchor is attached to the anchor chain at a distance of 3 to 5 meters from the main anchor.

[0022] The beneficial effects of this utility model are:

[0023] 1. By integrating the tide gauge station with the main anchor, the problem of equipment loss due to the vulnerability of independently deployed tide gauge stations to trawling operations is fundamentally solved. This invention significantly reduces the risk of loss of tide gauge observation equipment in deep-sea environments, ensuring the continuity of observation work and the integrity of data acquisition.

[0024] 2. When the wind and waves are relatively small, the secondary anchor plays the main anchoring role. However, when the wind and waves increase, the main anchor and the secondary anchor work together to enhance the anchoring effect, improve the positioning stability of the entire tide level observation platform on the seabed, reduce the station displacement and vibration caused by ocean currents and other factors, and improve the data quality of the tide level station.

[0025] 3. The original method of independently setting up tide gauge stations and wave observation points requires a lot of manpower, material resources and financial resources. However, this invention creatively combines the two, reducing the materials and costs required to set up multiple stations separately, realizing resource sharing and greatly saving construction and operation and maintenance costs.

[0026] 4. Combining the tide level observation station with the wave observation buoy allows for simultaneous measurement of observation data on the same platform, simplifying the operational process and improving work efficiency. Simultaneously, the tide level station is mounted on a specially designed and modified buoy anchor, enhancing its resistance to ocean current impacts and ensuring stable operation in complex deep-sea environments, thereby improving the accuracy of tide level observation data.

[0028] 1. Wave observation buoy body; 2. Main anchor; 3. Sleeve; 4. Secondary anchor; 5. Anchor chain. Detailed Implementation

[0029] Example 1: This example is a tide gauge system, including: tide gauge, main anchor, secondary anchor and anchor chain, etc.

[0030] In this example, the main anchor can use its own weight to embed itself partially or completely into the seabed silt. A sleeve is embedded or installed on the main anchor, and a tide gauge is installed inside the sleeve to ensure that the tide gauge can accurately sense and record tidal changes while anchoring.

[0031] In this embodiment, the anchor chain is attached to the main anchor, and a secondary anchor is connected in parallel on the anchor chain at a distance of 3 to 5 meters from the main anchor.

[0032] Example 2: This example is a wave observation buoy system integrated with a tide gauge station, including: wave observation buoy body, tide gauge, main anchor, secondary anchor and anchor chain, etc.

[0033] In this example, the main anchor can use its own weight to embed itself partially or completely into the seabed silt. A sleeve is embedded or installed on the main anchor, and a tide gauge is installed inside the sleeve to ensure that the tide gauge can accurately sense and record tidal changes while anchoring.

[0034] In this embodiment, the anchor chain connects the main anchor and the main body of the wave observation buoy, and a secondary anchor is connected in parallel on the anchor chain at a distance of 3 to 5 meters from the main anchor.

[0035] The specific implementation steps of this embodiment are as follows:

[0036] 1. Buoy Anchor Upgrade: First, based on the annual wave observation buoy and the sea conditions at the deployment locations, the anchoring system of the buoy will be upgraded. A large, sufficiently heavy main anchor will be added, with a sleeve designed and installed on it to serve as the mounting carrier and observation platform for the tide gauge.

[0037] 2. Tide gauge installation: Design a sleeve structure that can be embedded or installed on the wave buoy anchor body to fix the tide gauge in a special sleeve on the buoy anchor, and ensure that the tide gauge can accurately sense and record tidal changes while anchored.

[0038] 3. Deployment and Implementation: According to the pre-planned observation location, first deploy wave observation buoys to the designated sea area, and then slowly lower the large main anchor equipped with a tide gauge to the seabed using a special cable. The weight of the main anchor itself will cause it to be partially or completely embedded in the seabed silt, ensuring the stability of the observation platform.

[0039] 4. Dual-Anchor Reinforcement System: A unique anchoring strategy is employed, with a secondary anchor connected in parallel at an appropriate location on the main anchor chain (e.g., 3 to 5 meters). In calm seas, the secondary anchor provides the primary anchoring, while in rougher conditions, the main and secondary anchors work together to enhance the overall stability of the tide level observation platform on the seabed, reducing station displacement and vibration caused by currents and other factors, and improving the data quality of the tide level station.

[0040] 5. Data Acquisition and Instrument Recovery: At the end of the regular maintenance or observation period of the tide gauge station, a vessel must be dispatched to the site to recover the large main anchor carrying the tide gauge. Because the tide gauge station employs an anchoring system linked to the buoy, the risk of loss is greatly reduced, and its safety is significantly ensured. Furthermore, the recovery operation of the tide gauge station becomes relatively simple, which helps to save resources.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
