Description

Technical Field

[0001] The present invention relates to the technical field of ocean monitoring, and more particularly to a buoy system. Background Art

[0002] Marine environmental monitoring is an important means of developing marine economy, marine environmental protection, marine disaster prediction and early warning. In the marine dynamic and ecological three-dimensional monitoring system, buoys are indispensable as a hydrological and meteorological automatic monitoring equipment anchored on the sea surface and can be deployed near the coast or in the deep sea. It can work continuously for a long time under the extreme working environment conditions of the designed deployment sea area. Buoys are not only platforms for the installation of various meteorological and oceanographic monitoring instruments, but also working platforms for the acquisition and processing of monitoring data and data communication transmission. At present, the marine buoy platforms in my country's offshore and offshore waters are generally marine buoys with a diameter of 1m to 10m. The materials used to build the buoys are generally made of all-steel welding and composite materials. However, due to the integrated design of the buoys, when the buoys are damaged, they cannot be repaired. In addition, the installation of the buoys is bulky and requires large ships to install, which is labor-consuming, time-consuming and energy-consuming.

[0003] At present, there are also marine buoy devices that can splice multiple buoys into a floating body, such as the Chinese patent "A modular marine buoy device" (Announcement No.: CN 208007229 U, announcement date 2018.10.26), which discloses a modular marine buoy device, which includes: a solar bracket, a buoy bracket and a buoy float, the solar bracket is fixedly installed on the upper part of the buoy bracket, and the buoy bracket is used to support the buoy float; the buoy float includes a number of buoy modules arranged around the buoy bracket, and adjacent buoy modules are connected and fixed to the buoy bracket by fasteners. The solar bracket is also provided with a GPS signal light, an X-shaped keel, a bracket staircase and a mark warehouse; the patent adopts a design of splicing multiple buoy modules, which effectively reduces the difficulty of installing the marine buoy device and is conducive to the repair of the marine buoy device after damage. However, this patent simply splits the buoy into multiple buoy modules, and the volume of the buoy modules is still large, which is not conducive to transportation and loading and unloading. In order to fix the buoy modules, a buoy bracket and an X-shaped keel need to be set in the center of the buoy for support, which wastes a lot of space of the buoy and is not conducive to integrating multiple monitoring equipment on the buoy. Summary of the invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a buoy system that realizes structural modularization, simplifies the production process, facilitates transportation and loading and unloading, can be deployed and recovered by small and medium-sized fishing vessels and engineering vessels, reduces the cost of using ships, and optimizes its internal space structure. Various equipment can be installed in the buoy to meet monitoring requirements.

[0005] The technical solution adopted by the present invention is a buoy system, comprising: a buoy body; and an anchoring device, which is arranged below the buoy body and is used to stabilize the buoy body, and the buoy body comprises: a main cabin, at the bottom of which the anchoring device is arranged; a mast, which is arranged above the main cabin; a plurality of brackets, which surround the side of the main cabin; and a plurality of outer wall components, which are fixed on the brackets and fixed on the outer side of the main cabin, and form a closed floating chamber with the brackets and the side of the main cabin.

[0006] In the present technical solution, the bracket and outer wall assembly surrounding the side of the main cabin and the side of the main cabin form a closed floating chamber to provide buoyancy for the main cabin. The bracket plays a reinforcing role and has a certain anti-collision function. It optimizes the internal space structure. The main cabin can be set in the center of the buoy to install a variety of marine detection equipment and batteries to avoid space waste and meet monitoring requirements. Among them, the bracket and side wall assembly are both detachable and installable. The factory can produce these components in modularization during production, which reduces the production cost compared with integrated production. Moreover, it only needs to transport these components to coastal ports and other suitable installation locations for modular on-site assembly, saving transportation space and facilitating workers' transportation and loading and unloading. 100-300 ton fishing vessels and engineering ships can be used for deployment and recovery, reducing the cost of transportation ships; the bracket and outer wall assembly can be stacked during transportation, which can save more space compared with other buoys that simply divide the float into several floating blocks; by selecting brackets and outer wall assemblies of different specifications, the buoy body can be formed into different sizes, which is flexible to use.

[0007] Furthermore, the bracket is in the shape of a right-angled trapezoid with its waist slanting downward, and the bottom of the right-angled trapezoid is installed on the side of the main cabin, so that the upper part of the enclosed floating chamber is a cylinder and the lower part is an inverted frustum.

[0008] In the present technical solution, a right-angled trapezoidal bracket is provided to form a closed floating chamber with a cylindrical upper portion and an inverted frustum at the lower portion, so that the buoy body forms a navigation mark structure. When the buoy system is towed and deployed by a fishing boat, the buoy system can be towed steadily close to the stern of the fishing boat and is not prone to tilting so that the buoy body is exposed to the waves. The distance between the buoy system and the fishing boat during towing is greatly reduced, thereby avoiding affecting the safety of passing ships' navigation due to the excessive length of the towing cable.

[0009] Preferably, the bracket and the outer wall component are both made of stainless steel.

[0010] Preferably, the outer surface of the outer wall assembly is coated with a yellow anti-corrosion paint film.

[0011] In the present technical solution, since the buoy system is used for ocean monitoring, a yellow paint film is coated on the outer surface of the outer wall component according to industry standards to serve as a warning to passing ships; the yellow paint film is an anti-corrosion paint film, which can effectively prevent corrosion of the outer wall and extend the life of the buoy system.

[0012] Furthermore, it also includes a plurality of auxiliary buoyancy blocks filled in the closed buoyancy chamber.

[0013] Preferably, the auxiliary buoyancy block is made of a soft buoyancy polymer material.

[0014] Preferably, the number of the bracket, the outer wall assembly and the auxiliary buoyancy blocks are 6 each.

[0015] In the present technical solution, auxiliary buoyancy blocks are selected to fill the enclosed floating chamber, so that the space inside the buoy body can be utilized as much as possible to avoid waste and provide good buoyancy. The auxiliary buoyancy blocks made of soft buoyancy polymer materials can improve the anti-collision function of the buoy body. During use, if the outer wall assembly is damaged, the auxiliary buoyancy blocks can prevent seawater from entering, so that the buoy body has an anti-sinking function. Through the combination of the bracket, the outer wall assembly and the auxiliary buoyancy blocks, compared with the integrated buoy, its total weight is reduced by nearly half, reducing manufacturing costs, facilitating the hoisting of the buoy ship at sea, and avoiding rust corrosion and biological corrosion as much as possible.

[0016] Preferably, the buoy system also includes a flow rate detection device installed at the bottom of the main cabin, including: a flow meter cabin, which is arranged in the center of the main cabin and extends downward, and the bottom of the flow meter cabin is a sound-permeable plate to block seawater and transmit sound waves; an acoustic flow meter, which is arranged in the flow meter cabin to detect the flow field of the water area where the buoy system is deployed; and a hatch cover, which is installed on the top of the flow meter cabin.

[0017] Preferably, the acoustic flow meter is an acoustic Doppler flow profiler.

[0018] In the present technical solution, a flow meter cabin is arranged in the center of the main cabin to accommodate the acoustic flow meter, and a sound-permeable plate is selected as the bottom of the flow meter cabin so that sound waves can penetrate the flow meter cabin and the acoustic flow meter can work normally. When in use, distilled water needs to be injected into the flow meter cabin to ensure that the pressure inside and outside the flow meter cabin is balanced and the instrument maintains a good posture. The flow meter cabin and the sound-permeable plate separate the acoustic flow meter from seawater to avoid corrosion caused by direct contact with seawater. At the same time, it can also prevent impurities or organisms in seawater from attaching to the acoustic flow meter and causing biological corrosion, thereby ensuring the normal operation of the acoustic flow meter and extending its service life.

[0019] Preferably, a plurality of reinforcement parts are arranged at equal intervals around the side of the extension of the flow meter cabin body to connect the flow meter cabin body with the bottom of the main cabin body.

[0020] More preferably, a mounting hole is provided on the reinforcement portion to connect the mooring system.

[0021] Preferably, the buoy system further comprises an instrument installation well, which is arranged on the main cabin and penetrates the main cabin so that its bottom is in contact with seawater; an installation well cover is arranged at the bottom of the instrument installation well.

[0022] In this technical solution, an instrument installation well with a bottom in contact with seawater is provided on the main cabin, so that various monitoring equipment can be installed on the main cabin to detect the seawater. The installation well cover can effectively protect the equipment in the instrument installation well.

[0023] Preferably, the mast is a tower, which can be a single-layer, double-layer or triple-layer tower according to different specifications of the bracket and the outer wall assembly.

[0024] Preferably, the buoy system also includes an identification device installed on the mast, including: an AIS ship identifier, arranged at the top of the mast, for transmitting signals during the day to remind passing ships to avoid; a main anchor light, arranged at the top of the mast; and a plurality of auxiliary anchor lights, arranged at equal intervals around the middle of the mast, cooperating with the main anchor light to provide lighting warnings at night.

[0025] In the present technical solution, a visual recognition device is installed on the mast to serve as a warning to passing ships. The AIS ship identifier transmits signals and records ship information during the day, and broadcasts its dynamic and static data through the positioning system to issue navigation warnings to passing ships to remind them to give way. The main anchor light is installed on the top of the mast to serve as the main lighting warning. Considering that small fishing boats are also in danger of colliding with buoys when operating near the shore, four auxiliary identification anchor lights in different directions are installed at equal intervals around the middle of the mast to cooperate with the main anchor light to enhance the buoy light warning effect at night.

[0026] Preferably, a mast platform is provided on the upper part of the mast, and a meteorological observation device and / or a solar panel are installed on the mast platform.

[0027] Preferably, a solar lithium-sulfur battery is arranged in the main cabin to provide electrical energy for the buoy system.

[0028] In this technical solution, solar lithium-sulfur batteries are selected to replace traditional original lead-acid batteries, which can reduce battery usage and occupied space, expand the available space in the main cabin, and greatly reduce the ballast of the buoy body.

[0029] Preferably, the mooring system includes: a connecting ring; two or more anchor chains of equal length, whose upper ends are connected to the bottom of the main cabin and whose lower ends are connected through the connecting ring; a main anchor chain, whose upper end is connected to the anchor chain through the connecting ring; a sinker, connected to the lower end of the main anchor chain, for providing weight to stabilize the buoy body; a drag chain, one end of which is connected to the sinker; and an anchor body, connected to the other end of the drag chain to grab the bottom of the water to stabilize the buoy body.

[0030] More preferably, the upper end of the anchor chain is connected to the bottom of the main cabin through the mounting hole of the reinforcement part.

[0031] More preferably, the number of the anchor chains is two, forming a "Y"-shaped saddle structure.

[0032] In the present technical solution, the anchor chain adopts a full anchor chain to form a "Y"-shaped saddle structure. When the buoy body is hit, the impact force can be balanced to make the buoy body quickly recover to stability. The anchor chain can be designed according to factors such as the water depth, bottom quality, tidal range, and extreme wave height of the water area where the buoy system will be deployed. The stability counterweight is omitted, and it can withstand various harsh marine environmental conditions and extend the life of the mooring system to reduce the annual ship retrieval and deployment costs and the workload of management personnel. The sinker can be used to protect the anchor body. When hit, the main anchor chain pulls the sinker instead of directly pulling the anchor body, which improves the anchoring effect and enables the buoy system to be used for a long time without displacement, making it difficult for fishing boats to drag.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows: the bracket and side wall components in the buoy system of the present invention are detachable and installable, realizing structural modularization and simplifying the production process; the bracket and outer wall components can be stacked during transportation, which is convenient for transportation and loading and unloading; small and medium-sized fishing vessels and engineering ships can be used for deployment and recovery, reducing the cost of ship use, and optimizing its internal space structure; a variety of equipment can be installed in the buoy to meet monitoring requirements; the total weight is greatly reduced by combining the bracket, outer wall components and auxiliary buoyancy blocks, which is convenient for the buoy ship to hoist at sea; the mooring system can be firmly anchored and can withstand harsh marine environmental conditions, so that the buoy system can avoid electrolytic corrosion, rust corrosion and biological corrosion in the high temperature, high humidity and high salt marine environment conditions, so as to ensure that the buoy system is safe and reliable and does not need to be replaced after long-term use.

DETAILED DESCRIPTION

[0039] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0040] Example 1

[0041] like Figures 1 to 3 As shown, this embodiment provides a buoy system, including a buoy body 100 and an anchoring device 200.

[0042] The buoy body 100 includes: a main cabin 111, a mast 120, a plurality of brackets 112 and a plurality of outer wall components 113. The anchoring device 200 is arranged at the bottom of the main cabin 111, and the mast 120 is arranged above the main cabin 111. In the present embodiment, the brackets 112 and the outer wall components 113 are made of stainless steel. As shown in the figure, there are 6 brackets 112 and 6 outer wall components 113. The brackets 112 are arranged around the side of the main cabin 111. The outer wall components 113 are fixed to the brackets 112 through the fasteners 113 on the brackets 112, and are fixed to the outer side of the main cabin 111, and form a closed floating chamber with the brackets 112 and the side of the main cabin 111 to provide buoyancy for the main cabin 111. According to industry standards, a yellow paint film is coated on the outer surface of the outer wall components 113 to serve as a reminder and warning to passing ships.

[0043] The bracket 112 and the outer wall assembly 113 are detachable and can be produced in modules during production. These components can be transported to coastal ports and other suitable installation locations for modular on-site assembly, which saves transportation space, facilitates workers' transportation and loading and unloading, and reduces the cost of transportation ships. The bracket 112 and the outer wall assembly 113 can be stacked during transportation, which saves more space than other buoys that simply divide the floating body into several floating blocks. By selecting brackets 112 and outer wall assemblies 113 of different specifications, the buoy body 100 can be formed into a diameter of 3 meters, 6 meters or 10 meters. The mast 120 is a tower, and different model combinations can be selected according to the specifications of the assembled buoy body 100. For example, when the diameter of the assembled buoy body 100 is 3 meters, a single-layer tower can be selected; when the diameter of the buoy body 100 is 6 meters, a two-layer tower can be selected; when the diameter of the buoy body 100 is 10 meters, a three-layer tower can be selected.

[0044] like Figure 4 As shown, the bracket 112 is in the shape of a right-angled trapezoid with its waist slanting downward, and the bottom of the right-angled trapezoid is installed on the side of the main cabin 111, so that the upper part of the enclosed floating chamber is a cylinder and the lower part is an inverted cone, so that the buoy body 100 forms a navigation mark structure. When the buoy system is towed and deployed by a fishing boat, the buoy system can be stably towed close to the stern of the fishing boat, and it is not easy to tilt so that the buoy body 100 is on the surface of the waves, which greatly reduces the distance between the buoy system and the fishing boat during towing, and avoids affecting the safety of passing ships due to the excessive length of the tow cable.

[0045] In this embodiment, a number of auxiliary buoyancy blocks made of soft buoyancy polymer material are filled in the closed floating chamber to utilize the space in the buoy body 100 as much as possible to avoid waste and provide good buoyancy. The number of the auxiliary buoyancy blocks is six. The auxiliary buoyancy blocks made of soft buoyancy polymer material can improve the anti-collision function of the buoy body 100. During use, if the outer wall component 113 is damaged, the auxiliary buoyancy blocks can prevent seawater from entering, so that the buoy body 100 has an anti-sinking function. Compared with the integrated buoy, the amount of steel used is reduced, the total weight is reduced, the manufacturing cost is reduced, it is convenient for the offshore buoy ship to lift and place, and rust corrosion and biological corrosion can be avoided as much as possible.

[0046] A flow velocity detection device is arranged in the center of the main cabin 111, which includes a flow meter cabin 131, a sound-permeable plate 132, an acoustic flow meter and a hatch 133. The flow meter cabin 131 is arranged in the center of the main cabin 111 and extends downward. The bottom of the flow meter cabin 131 is a sound-permeable plate 132, so that sound waves can penetrate the flow meter cabin 131, so that the acoustic flow meter can work normally. The acoustic flow meter is an acoustic Doppler flow profiler, which is installed in the flow meter cabin 131 to detect the flow field of the water area where the buoy system is deployed. The hatch 133 is installed on the top of the flow meter cabin 131 to protect the acoustic flow meter. When in use, distilled water needs to be injected into the current meter cabin 131 to ensure that the pressure inside and outside the current meter cabin 131 is balanced, so that the instrument maintains a good posture. The current meter cabin 131 and the sound-permeable plate 132 separate the acoustic current meter from the seawater to prevent the acoustic current meter from directly contacting the seawater and corroding. At the same time, it can also prevent impurities or organisms in the seawater from attaching to the acoustic current meter and causing biological corrosion, thereby ensuring the normal operation of the acoustic current meter and extending its life. A number of reinforcement parts 134 are arranged at equal intervals on the side of the extension of the current meter cabin 131, connecting the current meter cabin 131 and the bottom of the main cabin 111 for reinforcement. At the same time, a mounting hole is set on the reinforcement part 134, and the mooring system is installed in the mounting hole to be connected to the buoy body 100.

[0047] In this embodiment, an instrument installation well 141 whose bottom contacts the seawater is provided on the main cabin 111 so that a variety of monitoring equipment can be provided on the main cabin 111 to detect the seawater. The installation well cover 142 can effectively protect the equipment in the instrument installation well 141.

[0048] The buoy system also includes an identification device installed on the mast 120, which includes an AIS ship identifier 151, a main anchor light 152 and a plurality of auxiliary anchor lights 153. The AIS ship identifier 151 is arranged at the top of the mast 120, and is used to send signals during the day to remind passing ships to avoid. Specifically, it sends signals during the day and records ship information, and broadcasts its dynamic data and static data through the positioning system to issue navigation warnings to passing ships to remind passing ships to avoid. The main anchor light 152 is arranged at the top of the mast 120, and plays a major lighting warning role at night. In addition, a plurality of auxiliary anchor lights 153 are arranged at equal intervals around the middle of the mast 120. Through the cooperation of the main anchor light 152 and the auxiliary anchor light 153, the lighting distance is farther and the brightness is greater than that used by the 6-meter and 10-meter buoys, thereby improving the lighting warning function of the buoy at night and further avoiding collision of small fishing boats near the coast when operating.

[0049] Solar lithium-sulfur batteries are installed in the main cabin 111 to replace traditional lead-acid batteries to provide power for various devices in the buoy system. Solar lithium-sulfur batteries can reduce battery usage and occupied space, expand the available space in the main cabin, and greatly reduce the ballast of the buoy body 100.

[0050] In this embodiment, the mooring system is arranged below the buoy body 100, and is used to stabilize the buoy body 100, and includes a connecting ring 210, two or more anchor chains 220 of equal length, a main anchor chain 230, a sinker, a drag chain and an anchor body. As shown in the figure, in this embodiment, the anchor chain 220 is a full anchor chain structure, and there are two of them, and the upper end thereof is connected to the bottom of the main cabin 111 through the mounting hole of the reinforcement part 134, and the lower end is connected through the connecting ring 210 to form a "Y"-shaped saddle structure, the upper end of the main anchor chain 230 is connected to the anchor chain 220 through the connecting ring 210, and the lower end is connected to the sinker (not shown), one end of the drag chain (not shown) is connected to the sinker, and the other end is connected to the anchor body, and the anchor body grabs the bottom of the water to stabilize the buoy body 100. When the buoy body 100 is hit, the anchor chain structure with a "Y"-shaped saddle structure can balance the impact force and make the buoy body 100 quickly restore stability. The anchor chain 220 can be designed according to factors such as the water depth, bottom quality, tidal range, and extreme wave height of the water area where the buoy system will be deployed. It omits the stabilizing weight, can withstand various harsh marine environmental conditions, and extend the life of the mooring system to reduce the annual ship recovery and deployment costs and the workload of management personnel; the sinker can be used to protect the anchor body. When hit, the main anchor chain 230 pulls the sinker instead of directly pulling the anchor body, which improves the anchoring effect, makes the buoy system not displaced during long-term use, and is difficult for fishing boats to drag. In the high temperature, high humidity, and high salt marine environment, electrolytic corrosion, rust corrosion, and biological corrosion are avoided to ensure the safety and reliability of the buoy system, and it does not need to be replaced after long-term use.

[0051] Example 2

[0052] The difference between this embodiment and the first embodiment is that the mooring device 200 selects a hybrid structure of anchor ropes instead of a full anchor chain structure, and one or more sections of cables are connected in the middle of the anchor chain 220. The cables are connected to the anchor chain 220 through a connecting member, and the connecting member includes a cable sheath, an anti-pressure washer and at least one cable fixer. The cable sheath has a curved tube cross section, on which a wear-resistant sleeve and a reinforcing connecting plate are provided, and an anti-extrusion washer is provided at the lower end of the cable sheath. After the cable passes through the two through holes of the cable sheath and the anti-extrusion washer, a cable knot is provided, and a cable fixer and a cable knot are provided at intervals below the cable knot. A terminal cable knot is provided between the end of the cable and the cable body below the last rope fixer. The mooring device 200 of this embodiment is used to fix the buoy body 100, so that the buoy system can be applied to deep sea waters.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
