Background technique

Marine buoy is an automatic observation station for marine hydrology, water quality and meteorology composed of observation buoys anchored at sea. Marine buoys can be used for long-term and continuous marine scientific research, offshore oil and gas development, port construction or national defense according to regulations. Construction and collection of required marine hydrology, water quality and meteorological data. Existing marine buoys are generally composed of buoy bodies, system main control cabins, solar panels, thermometers, mooring frames, sensors, anchor chains, counterweight blocks and other structures. The marine buoy is sent to the designated position, and the marine buoy will be put into the sea through the launching device, the counterweight will sink to the bottom of the sea, and the buoy will float on the sea surface.

It supplies power to the instruments in the main control cabin of the system. Since there are always waves or water waves on the sea surface, the movable floating rod will always float. Therefore, the conductor rod can always do the motion of cutting the magnetic field line, and then provide current continuously, so that the The instrument can be powered for a long time without power outage, which effectively avoids the existing single use of solar power to generate electricity, and then the existing solar energy cannot generate electricity due to the influence of weather conditions, resulting in the failure of the instruments in the main control cabin of the system to operate normally, seriously reducing the The problem of information collection efficiency.

2. The present invention makes use of the small holes opened on the inner side wall of the protective layer by setting the protective layer, so that when the seawater flows to the periphery of the buoy body, it first flows into the inner wall of the opening on the outer surface of the protective layer, and through the small holes, the aquatic algae and Microorganisms cannot pass through the pores and filter the seawater, thereby reducing the content of aquatic algae and microorganisms in the seawater around the buoy body, thereby effectively reducing the degree of contamination on the surface of the buoy body, keeping the surface of the buoy body always clean, avoiding algae corrosion, and strengthening the buoy body.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to Fig. 1-Fig. 4, a marine buoy communication device, including a buoy body 1, an anchor chain 2 is fixedly installed in the middle of the bottom end of the buoy body 1, a system main control cabin 3 is fixedly installed in the middle of the top end of the buoy body 1, and the buoy A fixed block 4 is fixedly installed on the outer surface of the body 1, a movable floating rod 5 is movably installed on the outer surface of the fixed blocking block 4, a fixed balance bottom block 6 is fixedly installed at the bottom end of the movable floating rod 5, and the top of the movable floating rod 5 is fixed A transmission rod 7 is installed, a conductor rod 8 is fixedly installed at the bottom end of the transmission rod 7, a magnet block 9 is fixedly installed at the top of the system main control cabin 3, and a sealing shell 10 is fixedly installed on the outside of the magnet block 9. An algae cleaning plate 11 is fixedly installed on the outer surface of the bottom, and a protective layer 12 located outside the algae cleaning plate 11 is fixedly installed on the outside of the buoy body 1 . The inner cavity in the middle of the surface is provided with a bellows 14 .

Please refer to FIG. 2-FIG. 4, wherein, there are eight movable floating rods 5 in total, and the height values of the two movable floating rods 5 located on the left and right sides and facing each other are greater than the height values of the other movable floating rods 5. The movable floating rods 5 The inner surface of the inner surface is provided with a channel matching the size of the fixed block 4, and the inner cavity of the movable floating rod 5 is hollow and filled with gas. By setting the movable floating rod 5, when waves are generated on the sea surface, the Float up and down, and then make the movable floating rod 5 float up and down with the waves. When the movable floating rod 5 fluctuates up and down, the movable floating rod 5 drives the transmission rod 7 to move up and down, and the transmission rod 7 drives the conductor rod 8 to move up and down again. The magnetic field lines generated by the magnet block 9 are perpendicular to the direction of movement of the conductor rod 8, and when the conductor rod 8 moves up and down, the magnet block 9 is continuously cut to the magnetic field line movement, thereby generating current, which is then conducted through the conductor rod 8. , and then the current can be sent to the main control cabin 3 of the system, so as to supply power to the instruments inside the main control cabin 3 of the system, and because the ocean surface will always generate waves or water waves, therefore, the movable floating rod 5 always has a floating action, and then It is also possible to make the conductor rod 8 move up and down all the time, so that the current can be supplied intermittently, so that the instrument can be powered for a long time, effectively avoiding the existing solar power generation. The instruments in the main control cabin 3 of the system cannot operate normally, which seriously reduces the efficiency of information collection.

Please refer to FIG. 2 to FIG. 3 , wherein the magnet block 9 has magnetism, and the N pole and the S pole of the magnet block 9 are respectively located outside the two sides of the conductor rod 8 .

Please refer to FIG. 2 to FIG. 4 , wherein the shape of the algae cleaning plate 11 is a circular arc, and the curvature value of the algae cleaning plate 11 is adapted to the curvature value of the inner side wall of the protective layer 12 . The surface is provided with bristles, and the outer upper surface of 11 is provided with rigid wear-resistant rods. By setting the algae cleaning plate 11, the fluctuations generated by the sea surface are used to make the movable floating rod 5 fluctuate up and down. When the movable floating rod 5 fluctuates up and down The movable floating rod 5 drives the algae cleaning plate 11 to move up and down together. When the algae cleaning plate 11 moves up and down, the bristles on the surface of the algae cleaning plate 11 continuously sweep up and down the openings on the inner side wall of the protective layer 12, so that the inner wall of the small hole is The attached aquatic algae and microorganisms are brushed off, so as to avoid blockage of the openings on the surface of the protective layer 12, thereby affecting the filtering effect of the protective layer 12 on the aquatic algae and microorganisms, so that the seawater rushing to the surface of the buoy body 1 can always be filtered, not It will contain a large amount of aquatic algae and microorganisms, so that the surface of the buoy body 1 can maintain a certain degree of cleanliness, effectively protect the surface of the buoy body 1 from corrosion by algae and microorganisms, and prolong the service life of the buoy body 1 .

Please refer to FIG. 1 to FIG. 3 , wherein the overall shape of the protective layer 12 is a circular ring, the outer surface of the protective layer 12 is a hollow structure, and the hollowed holes are hexagonal and evenly arranged and distributed. The protective layer 12 Small holes are opened on the surface of the inner side wall of the protective layer 12, and the positions of the small holes are matched with the positions of the hollow holes set on the outer surface of the protective layer 12. The surface of the protective layer 12 has elasticity. By setting the protective layer 12, when the buoy body 1 When floating in the ocean, the seawater continuously flows through the surface of the buoy body 1, and at the same time, it also flows through the surface of the protective layer 12. When the seawater containing aquatic algae and microorganisms flows through the surface of the protective layer 12, the protective layer 12 The outer surface is hollow, and the seawater flows into the inner wall of the opening, and then passes through the small holes inside the opening. Because the aquatic algae and microorganisms cannot pass through the pores, the seawater flowing into the protective layer 12 is directly filtered by the small holes, and the aquatic algae cannot pass through the pores. and microorganisms are blocked outside the small holes, that is, left in the hollow hole wall on the outer surface of the protective layer 12, and the filtered seawater flows out of the inner side wall of the protective layer 12 and contacts the surface of the buoy body 1, so the buoy body 1 The surrounding seawater contains low levels of algae and microorganisms, which effectively reduces the degree of contamination on the surface of the buoy body 1, so that the surface of the buoy body 1 is always kept clean, thereby avoiding algal corrosion, effectively enhancing the durability of the buoy body 1, and protecting the ocean. Collection work has a facilitation effect.

In addition, by setting the protective layer 12 to be a hexagonal arrangement structure, according to the principle and characteristics of the honeycomb structure, the hexagonal structure has higher stress resistance, and the constructed structure is light in weight, so the protective layer 12 has a pressure resistance Due to the light weight of the protective layer 12, the external burden of the buoy body 1 will not be increased, and the buoy body 1 can still maintain good buoyancy, while the protective layer 12 is hollowed out as a hexagonal core In addition, when the buoy body 1 is impacted by the outside, the outer surface of the protective layer 12 can effectively buffer the external impact object, and make itself stress, so as to prevent the impact force from being transmitted to the buoy body 1, so as to achieve vibration isolation. It can effectively protect the buoy body 1 and the internal instrument structure of the system main control cabin 3 from being damaged, and avoid damage to the existing buoy body 1 due to external impact. The structure of layer 12 is lighter. Compared with the flat wall surface of the rubber ring, there are more force supporting points on the wall surface of the structure, so that the force is stabilized and buffered. The weight is heavier, which increases the burden on the top of the buoy body 1 and causes the buoy body 1 to float too much, which is not conducive to the floating of the main control cabin 3 of the system for effective information collection.

Please refer to FIGS. 1-3 , wherein the shape of the adjustment buffer bag 13 is adapted to the shape of the gap between the hexagonal structures distributed on the surface of the protective layer 12 , and the inside of the adjustment buffer bag 13 is hollow and filled with heat For gas that is easily inflated, such as carbon dioxide gas, the shape of the expansion bag 14 is also adapted to the shape of the gap between the hexagonal structures distributed on the surface of the protective layer 12. The interior of the expansion bag 14 is hollow and filled with gas, located in the The outer surface of the upper adjustment buffer bag 13 is provided with a fixed shaft, and one end of the fixed shaft is fixedly connected to the outer surface of the telescopic bag 14, and the top of the lower adjustment buffer bag 13 is provided with a through hole, and the through hole is connected to the telescopic bag 14. The bottom end of the bag 14 is connected, and the inner side wall surface of the adjustment buffer bag 13 located at the upper part is provided with a heat-conducting sheet, and the surface of the heat-conducting sheet is rough. Due to the flapping effect, the fluctuation range of the sea surface is different, so the impact force generated by the upper and lower parts is different. Combined with common knowledge, it can be known that when the waves are flapping, the upper part of the buoy body 1 is subjected to a large impact force, which easily causes the structure of the buoy body 1 to suffer. Therefore, the strong fluctuations generated by the ocean waves are used to make the movable floating rod 5 fluctuate, so that the movable floating rod 5 drives the algae cleaning plate 11 to move up and down. The rigid wear-resistant rod and the heat-conducting sheet on the inner side wall of the adjustment buffer bag 13 at the upper part generate strong friction, thereby generating a large amount of heat energy. The gas in the inner cavity of the buffer bag 13 causes the gas to expand by heating, so as to expand outward. When the adjustment buffer bag 13 located at the upper part expands, it passes through the fixed shaft, thereby driving the expansion bag 14 to expand outward, then the inside of the expansion bag 14 The volume becomes larger, so that the gas inside the adjustment buffer bag 13 located at the lower part is sucked back, and the adjustment buffer bag 13 located at the lower part contracts inwardly, so that the volume of the liquid discharged from the lower part of the buoy body 1 becomes smaller, so that the buoyancy becomes smaller, then the buoy The buoy body 1 floats downward, thereby reducing the distance of the upper impacted section, causing the buoy body 1 to temporarily sink into the sea, and increasing the bottom stability of the buoy body 1. At the same time, the adjustment buffer bag 13 located on the upper part, that is, above the sea surface, expands when heated. , then its internal air pressure increases, and through the action of air pressure, when the waves hit the surface of the protective layer 12, the adjustment buffer bag 13 can provide sufficient buffering, so that the impact on the surface of the protective layer 12 is reduced, and the protective layer 12 is strengthened in time against the waves. It can effectively protect 1 from damage and avoid the damage caused by sea waves. To sum up, by adjusting the change of the buffer bag 13, the protective layer 12 can be adjusted in time when the sea surface changes and strong waves are generated. The anti-pressure of the surface makes the protective layer 12 fully play a buffering effect, and makes the buoy body 1 temporarily sink or float, that is, it floats up and down with the fluctuation of the waves, so as to enhance the stability of the buoy body 1 in the sea and avoid the If the waves are too large, the protective layer 12 cannot fully buffer, and the floating distance of the buoy body 1 is long, resulting in the impact of the waves hitting the buoy body 1 . The hazard is extremely high, which in turn causes the buoy body 1 to be severely damaged due to excessive impact.

The working principle of the using method of the present invention is as follows:

When it is necessary to collect marine hydrology, water quality and meteorological information, the device of the invention is put into the sea by a ship, and the existing counterweight connected to the bottom end of the anchor chain 2 is put in, so that the counterweight sinks, thereby driving the entire inventive device Float down, when the counterweight completely sinks into the seabed and is fixed, at this time, due to air flotation, the buoy body 1, the movable float rod 5, and the protective layer 12 float together on the sea surface, while the system main control cabin 3 located at the top of the buoy body 1 , the transmission rod 7, the conductor rod 8, the magnet block 9, and the sealing shell 10 are all located on the sea surface. The body 1 is always fixed in place and will not move. According to the connection relationship between the device structures of the invention, the protective layer 12 is also kept fixed together with the buoy body 1 .

Therefore, when waves are generated on the sea surface, the fluctuations of the waves or currents will cause the movable floating rod 5 to float up and down. The top end drives the transmission rod 7 to move up and down, and the transmission rod 7 drives the conductor rod 8 to move up and down. When the conductor rod 8 moves up and down, the conductor rod 8 cuts the magnetic field line of the magnet block 9, thereby generating current. When the current is conducted through the conductor of the conductor rod 8 itself, and the existing wire assembly is used for transmission, the current is then transmitted to the main control cabin 3 of the system, through the existing power supply equipment, used for the internal detection instrument of the main control cabin 3 of the system powered by.

At the same time, when the fluctuation of the sea surface causes the movable floating rod 5 to move up and down, the movable floating rod 5 will also drive the algae cleaning plate 11 to move up and down together. Continuously sweep the small holes for filtering on the inner wall of the protective layer 12, so that the aquatic algae and microorganisms attached to the inner wall of the small holes are brushed off by the algae cleaning plate 11, so as to avoid the blocking of the openings on the surface of the protective layer 12, thereby affecting the protection layer 12. The filtering effect of aquatic algae and microorganisms.

When the collection of marine hydrology, water quality and meteorological information is no longer required, the buoy body 1 can be salvaged and recovered by using an existing ship.
