Description

Technical Field

[0001] The invention relates to the technical field of marine buoys, in particular to a marine detection buoy which generates electricity using tidal energy. Background Art

[0002] A marine buoy usually refers to a navigation mark with an indicator light floating on the sea surface, but now the role of buoys is becoming more and more diverse. The convenience of buoy setting can help surveyors to detect the ocean more conveniently, including measuring wind in some sea areas where it is not convenient to set up fixed wind towers, measuring sea water, etc.

[0003] Tidal energy, as a relatively easy-to-develop form of energy, has made great progress in recent years. It mainly uses energy conversion devices to convert the kinetic energy generated by the flow of seawater caused by tides into mechanical energy of the moving parts of the device, driving the generator to generate electricity. With the development of tidal energy, marine detection buoys that can use tidal energy to generate electricity have been developed. Using tidal energy to generate electricity can provide continuous power for detection equipment, data transmission systems, etc. on the buoy, reducing dependence on external power supplies and reducing operating costs. At the same time, it solves the problem of insufficient power supply for traditional buoys when there is insufficient sunlight.

[0004] Most of the existing offshore buoys that use tidal energy to generate electricity convert the kinetic energy generated by the flow of seawater through impeller blades. However, the seawater contains a large amount of large debris and floating objects, which will drift to the impeller blades as the seawater flows through the impeller blades. This can easily interfere with the operation of the impeller blades, reduce the energy efficiency of the mechanical energy of the impeller blades, and thus reduce the conversion efficiency of tidal energy. Long-term operation is more likely to cause blockage or restriction of the impeller blades, thereby affecting the normal operation of the impeller blades. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0031] See also Figures 1 to 4, which is the first embodiment of the present invention, provides a technical solution: an offshore detection buoy for generating electricity using tidal energy, comprising a floating board 1, a waterproof cover 2 is fixedly connected to the top of the floating board 1, a conversion box 3 is fixedly connected to the top of the waterproof cover 2, a battery and a generator are installed inside the conversion box 3, a monitoring component 4 is fixedly connected to the top of the conversion box 3, and a meteorological sensor is equipped inside the monitoring component 4, which can monitor meteorological elements such as wind speed, wind direction, temperature, and air pressure in real time, and transmit the data to a monitoring center on the shore, and at the same time, it is equipped with hydrological monitoring equipment to monitor the temperature of seawater. , salinity, tide, current and other hydrological parameters are measured and recorded, and a signal receiver and a controller are also provided inside to receive instructions from the onshore monitoring center to open and close the driving member 7. The bottom of the floating board 1 is fixedly connected to an impeller conversion member 6, and the conducting end of the impeller conversion member 6 is fixedly connected to the conversion box 3. The impeller conversion member 6 is driven by the tidal energy generated by the flow of seawater, which drives the impeller conversion member 6 to generate kinetic energy inside, thereby converting tidal energy into mechanical kinetic energy, and then using a generator to convert the mechanical kinetic energy into electrical energy, so as to generate electricity, and the converted electricity Energy can be stored by a battery so that the buoy can be self-powered. A detachable filter box 5 is installed at the bottom of the floating board 1. Here, the filter box 5 can be fixed to the bottom of the floating board 1 by strong bolts to prevent debris in the seawater from entering the impeller converter 6 to avoid affecting the operation of the impeller converter 6. When the filter box 5 needs to be replaced or maintained, the strong bolts can be removed to disassemble and maintain the filter box 5. The filter box 5 is covered on the outside of the impeller converter 6. Here, the filter box 5 is made of stainless steel. It has excellent resistance to pitting corrosion and crevice corrosion. At the same time, its surface is coated with polyurethane coating, which can form a protective film on the surface of the filter box 5, which can reduce the erosion of the filter box 5 by seawater. A connecting column is fixedly connected to one side of the bottom of the floating board 1, and a plurality of cleaning brushes 8 are rotatably connected to the connecting column. A transmission member 9 is fixedly connected to the bottom side of the floating board 1 away from the connecting column, and the cleaning brushes 8 are connected to the transmission member 9 in transmission connection. A driving member 7 is fixedly connected to the top of the floating board 1, and mutually symmetrical striking members 10 are installed on the floating board 1, and the driving member 7 is connected to the transmission member 9 and the striking member 10 in transmission connection.

[0032] The filter box 5 is used to block the debris in the seawater to prevent it from entering the impeller conversion element 6, and the water flow is used to drive the cleaning brush element 8 to rotate, move the seawater, speed up the circulation of seawater, and at the same time, simply clean the filter box 5. Afterwards, when cleaning the filter box 5, the driving element 7 drives the striking element 10 to intermittently strike the filter box 5, and moves the seawater inside the filter box 5 to speed up the water flow rate. At the same time, the driving element 7 synchronously drives the transmission element 9, so that the transmission element 9 drives the cleaning brush element 8 to speed up the rotation speed of the cleaning brush element 8.

[0033] The impeller conversion element 6 includes an impeller group 61 fixedly connected to the bottom of the floating plate 1. A plurality of blades for converting tidal energy are arranged inside the impeller group 61. The blades are made of titanium alloy, which is light in weight and can withstand the impact of high-speed water flow and temperature changes. At the same time, a layer of silicon-based coating is coated on the surface of the impeller to reduce the attachment of small organisms such as barnacles and algae in seawater to the impeller surface. A connecting box 62 is fixedly connected to the top of the impeller group 61, and a collecting cover 63 is fixedly connected to one side of the impeller group 61.

[0034] When the buoy is used, it can be placed on the sea first, and the buoy can be restricted by an external chain to place and install the buoy. When placed, the impeller group 61 is facing away from the shore. When in use, the marine conditions can be monitored by the monitoring component 4, and the monitoring data can be transmitted to the monitoring center on the shore in real time, so that people can monitor the marine conditions. When the buoy is in use, the flow of seawater can drive the blades inside the impeller group 61 to rotate, so that the impeller group 61 converts the tidal energy generated by the flow of seawater into mechanical kinetic energy, and converts the mechanical kinetic energy into electrical energy through the generator in the conversion box 3, and then transmits the converted electrical energy to the battery, so as to realize the conversion of tidal energy into electrical energy. The battery can be used to power the buoy itself, thereby improving the functionality of the buoy. The seawater can be guided by the collector 63 to increase the flow rate of seawater through the force-bearing block 51 and improve the tidal energy conversion efficiency of the force-bearing block 51. When the buoy is in use, the filter box 5 can be used to filter and block large debris and floating objects in the seawater, blocking them outside the filter box 5 to prevent them from entering the impeller group 61 and causing blockage therein and affecting its normal operation, thereby reducing the frequency of manual maintenance and increasing the working time of the buoy. When the buoy needs to be maintained, the strong bolts can be manually removed to remove the filter box 5, thereby making it convenient for people to replace or maintain the filter box 5.

[0035] When the filter screen box 5 is cleaning the debris and floating objects, the force generated by the flow of seawater drives the cleaning brush 8 to rotate. The rotating cleaning brush 8 can perform preliminary cleaning on the filter screen box 5, and can brush off the debris and floating objects adhering to the filter screen box 5, thereby reducing the possibility of clogging caused by the debris and floating objects adhering to the filter screen box 5, and realizing the self-cleaning function of the cleaning brush 8 on the filter screen box 5, ensuring the flow rate of water from the filter screen box 5. At the same time, when the water flow drives the cleaning brush 8 to rotate, the rotating cleaning brush 8 can clean the seawater. The water fluctuates, thereby increasing the speed of seawater circulation, thereby ensuring the circulation efficiency of seawater entering the filter box 5. Here, when the buoy is just put into use or when the seawater flows relatively slowly, the flow of seawater can drive the cleaning member 8 to realize the self-cleaning function of the filter box 5. If it encounters high tide or the seawater flows more turbulently, an instruction can be sent through the onshore monitoring center to open the driving member 7, thereby driving the transmission member 9 and the striking member 10 to operate, thereby driving the cleaning member 8 and the striking member 10 to further drive the filter box 5. Example 2

[0036] See also Figures 5 to 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the driving member 7 includes a waterproof motor 71 fixedly connected to one side of the top of the floating board 1. Here, the battery inside the conversion box 3 can provide power supply for the waterproof motor 71 to ensure the normal operation of the waterproof motor 71. The output end of the waterproof motor 71 is fixedly connected to a rotating shaft 72, and a flat gear 73 is fixedly connected to the rotating shaft 72. The end of the rotating shaft 72 close to the waterproof motor 71 is fixedly connected to an active disk 74.

[0037] The striking member 10 includes a connecting shaft 102 rotatably connected to the floating board 1, and a face gear 101 is fixedly connected to the top end of the connecting shaft 102, and the face gear 101 is meshed and connected with the flat gear 73. Here, both face gears 101 are meshed and connected with the flat gear 73. The two face gears 101 are driven by the rotation of the flat gear 73, so that the two face gears 101 rotate in relative directions, and drive the two water-displacing members to rotate in relative directions. The water-displacing members are installed on the connecting shaft 102.

[0038] The water-diverting member includes a second diverter plate 103 fixedly connected to the connecting shaft 102, and a detachable filter box 106 is installed on the second diverter plate 103. Here, the filter box 106 can be connected and fixed to the second diverter plate 103 by bolts. When it needs to be replaced, the bolts can be removed to replace it. The filter box 106 is filled with diatomaceous earth particles for adsorbing plankton and microplastics in seawater, reducing the possibility of plankton and microplastics adhering to the blades of the impeller group 61. An elastic impact plate is installed at one end of the second diverter plate 103 away from the connecting shaft 102.

[0039] The elastic striking plate includes a striking plate 104 rotatably connected to one end of the second dial plate 103, and a plurality of reset tension springs 105 are fixedly connected between the second dial plate 103 and the striking plate 104. A plurality of force blocks 51 are fixedly connected to the inner side of the filter box 5. Here, the plurality of force blocks 51 are classified and arranged as a group on the coaxial line, and a group is respectively arranged on two adjacent surfaces inside the filter box 5. On the rotation trajectory of the striking plate 104, the striking plate 104 can be rotated to strike the force block 51.

[0040] When the waterproof motor 71 is running, the rotating shaft 72 can be driven to rotate, and the rotating rotating shaft 72 can drive the flat gear 73 to rotate. The rotating flat gear 73 can synchronously drive the two face gears 101, so that the two face gears 101 rotate in relative directions, thereby driving the connecting shaft 102 to rotate. The rotating connecting shaft 102 can drive the second dial plate 103 to rotate. At this time, the two second dial plates 103 rotate in relative directions. The rotating dial plate 103 can be used to dial the seawater to increase the flow rate of the seawater. When the seawater is dialed, the second dial plate 103 can drive the filter box 106 to rotate, and the filter box 106 can adsorb plankton and microplastics in the seawater to reduce plankton. The possibility of organisms and microplastics adhering to the blades is reduced, so as to avoid affecting the rotation speed of the blades and ensure the tidal energy conversion efficiency of the blades. When the second paddle plate 103 rotates, it can drive the striking plate 104 to intermittently strike the force block 51, causing the filter box 5 to vibrate slightly, thereby shaking off the debris and floating objects attached to the filter box 5, and then cooperating with multiple cleaning brushes 8 to clean the filter box 5, thereby improving the cleaning efficiency of the filter box 5 and reducing the possibility of small debris clogging the filter holes of the filter box 5, thereby ensuring the circulation efficiency of the filter box 5. After the striking plate 104 strikes the force block 51, the second paddle plate 103 is pulled under the elastic action of the reset spring 105 to quickly reset it.

[0041] The remaining structures are the same as those of Example 1. Example 3

[0042] See also Figures 9 and 10 , which is the third embodiment of the present invention, is different from the first and second embodiments in that: the transmission member 9 includes a mounting box fixedly connected to the bottom of the floating board 1, and a plurality of transmission gears 91 are rotatably connected in the mounting box. A linkage member is fixedly connected to the top of the floating board 1, and the linkage member and the transmission gear 91 are connected through a synchronous belt 92.

[0044] The brush cleaning member 8 includes a rotating rod 81 rotatably connected to the connecting column, and a detachable cleaning member is installed on the brush cleaning member 8. An overrunning clutch 84 is installed at the end of the rotating rod 81 away from the connecting column. The overrunning clutch 84 is installed inside the installation box. The driving shaft of the overrunning clutch 84 is fixedly connected to the transmission gear 91. Here, the overrunning clutch 84 is divided into a driving shaft and a driven shaft, and the driving shaft is connected to the transmission gear 91, and the driven shaft is connected to the rotating rod 81. When the rotating rod 81 rotates, it can drive the driven shaft to rotate. At this time, the driving shaft is stationary. When the transmission gear 91 drives the driving shaft to rotate, it can drive the driven shaft to rotate, and then drive the rotating rod 81 to rotate.

[0045] The cleaning part includes a paddle plate 82 installed on the rotating rod 81, and a cleaning brush 83 is fixedly connected to one end of the paddle plate 82 away from the rotating rod 81, and a plurality of guide grooves are provided on the paddle plate 82. Here, the paddle plate 82 is made of titanium alloy, which is highly resistant to seawater corrosion, lightweight and high in strength, and a polytetrafluoroethylene coating is coated on its exterior, which can reduce the friction resistance of water flow on the surface of the paddle plate 82 and improve the rotation efficiency of the paddle plate 82. The guide groove can enhance the water flow guiding effect and improve the rotation efficiency of the paddle plate 82 driven by the water flow.

[0046] When the seawater flows, the paddle plate 82 can be pushed, so that the paddle plate 82 drives the rotating rod 81 to rotate, and then drives the cleaning brush 83 to rotate, thereby prying the seawater, increasing the flow rate of the seawater, ensuring the circulation efficiency of the seawater at the filter box 5, and at the same time driving the cleaning brush 83 to clean the filter box 5, thereby realizing the self-cleaning function of the filter box 5. When the rotating shaft 72 rotates, the active disk 74 can be driven to rotate. The rotating active disk 74 can drive the transmission disk 95 to rotate through the transmission belt 94, thereby driving the active gear 93 to rotate. The rotating active gear 93 can be driven by the synchronous belt 92 to rotate. The plurality of transmission gears 91 are driven to rotate synchronously, thereby driving the overrunning clutch 84 to rotate, thereby driving the rotating rod 81 to rotate, and then accelerating the plurality of paddle plates 82 to rotate in the direction of the filter box 5. Accelerating the paddle plate 82 can paddle the seawater, greatly increasing the flow rate of the seawater, thereby increasing the efficiency of the seawater flowing through the filter box 5, thereby increasing the tidal energy conversion efficiency of the impeller group 61. At the same time, when the paddle plate 82 rotates, it drives the cleaning brush 83 to clean the filter box 5, thereby clearing away the debris and floating objects adhering to the filter box 5, and improving the seawater circulation efficiency.
