Description

Technical Field

[0001] The utility model relates to a power generation device, in particular to an offshore generator. Background Art

[0002] New energy power generation refers to the process of generating electricity using solar energy, biomass energy, geothermal energy, hydrogen energy or ocean energy. New energy power generation methods are cleaner and effectively reduce pollution during the power generation process, such as current wind power generation and hydropower generation. For coastal cities, wave generators are usually used for power generation. The power generation method of wave generators mainly uses the kinetic energy generated by seawater flowing through them to convert into electrical energy. It has high requirements for the water flow speed on the sea surface, resulting in more limited use and low power generation efficiency. Therefore, there is an urgent need for a generator with higher power generation efficiency at sea. Utility Model Content

[0003] The purpose of the present utility model is to provide an offshore generator to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A marine generator comprises: a counterweight box with a first power supply provided inside; a wave power generation unit comprising a float, a swing arm, a sliding rod and a rocker arm, one end of the swing arm being rotatably connected to one side of the counterweight box, the float being rotatably connected to the other end of the swing arm, the top side of the swing arm protruding upward to form a connecting chamber, one end of the sliding rod being slidably connected to the connecting chamber, an electromagnetic induction device being provided between the sliding rod and the connecting chamber, the electromagnetic induction device being electrically connected to the first power supply, one end of the rocker arm being rotatably connected to the other end of the sliding rod, and the other end of the rocker arm being rotatably provided on the outside of the counterweight box.

[0006] This technical solution has at least the following beneficial effects: when in use, the entire offshore generator is placed on the sea surface, and the counterweight box can play a major stabilizing role to prevent the overall capsizing caused by excessive waves. The float floats on the water surface. When waves on the sea surface drive the float to move, the float swings on the outside of the counterweight box through the swing arm, and the slide rod on the swing arm and the rocker arm form a connecting rod mechanism. When the swing arm swings, it can drive the slide rod to slide relative to the connecting chamber, so that the electromagnetic induction device between the slide rod and the connecting chamber generates an induced current to charge the first power supply. In this way, the reciprocating swing of waves on the sea surface can be used to drive the slide rod to slide more frequently through the float, which is particularly suitable for locations close to the coast and greatly improves the power generation efficiency.

[0007] As a further improvement to the above technical solution, the wave power generation unit further includes a restraining member connected to the bottom side of the sliding rod, which is slidably connected to the top side of the swing arm along the length of the swing arm. A sliding connection is formed between the sliding rod and the connecting chamber, while another sliding connection is formed between the restraining member and the swing arm. This allows the sliding rod to slide more smoothly and stably relative to the connecting chamber, greatly improving the stability of the inductive sensing device.

[0008] As a further improvement to the above technical solution, the wave power generation unit further includes a connecting rod disposed between the rocker arm and the counterweight box. One end of the connecting rod is pivotally connected to the end of the rocker arm distal from the slide rod, and the other end of the connecting rod is pivotally connected to the exterior of the counterweight box. The slide rod is connected to the exterior of the counterweight box via the rocker arm and the connecting rod, thereby increasing the range of motion of the rocker arm driven by the float, thereby extending the sliding travel of the slide rod relative to the connecting chamber and further improving power generation efficiency.

[0009] As a further improvement to the above technical solution, multiple wave power generation units are arranged around the counterweight box. Waves impacting the counterweight box from different directions can have different degrees of impact on wave power generation units in different locations. The sliding rods in the wave power generation units facing the wave impact have a larger range of movement and higher power generation efficiency. In this way, by arranging multiple wave power generation units in different directions, power generation efficiency can be further improved.

[0010] As a further improvement to the above technical solution, the present invention also includes a wind power generation mechanism comprising a connecting frame, blades, and a generator. The generator is connected to the top side of the counterweight box. A downwardly extending connecting shaft is connected to the bottom side of the connecting frame. The connecting shaft is rotatably connected to the generator, which is electrically connected to the first power source. The connecting frame is connected to a plurality of blades surrounding the connecting shaft. The entire machine also has a wind power generation function. Specifically, sea breeze can blow towards the blades, which drives the connecting frame to rotate, driving the generator to generate electricity, charging the first power source, thereby further improving power generation efficiency.

[0011] As a further improvement to the above technical solution, the present invention further includes a solar power generation mechanism comprising a top frame and a solar panel. The top frame is mounted on the connecting frame, and the solar panel is mounted on the top frame, and the solar panel is electrically connected to the first power source. During use, the solar panel on the top frame converts solar energy into electrical energy to charge the first power source, thereby providing the entire system with solar power generation capabilities and further improving overall power generation efficiency.

[0012] As a further improvement to the above technical solution, the top frame is rotatably connected to the top side of the connecting frame. When the sea breeze blows towards the blades and drives the connecting frame to rotate, the rotatable connection between the top frame and the connecting frame can effectively reduce the phenomenon of the connecting frame driving the top frame to rotate, thereby improving the stability of solar charging.

[0013] As a further improvement to the above technical solution, a buoy light is connected to the top frame, and the first power supply is electrically connected to the buoy light. The first power supply supplies power to the buoy light, which provides an illumination function to facilitate identification of its position in a dark environment.

[0014] As a further improvement to the above technical solution, a second power source is connected to the top frame, and the solar panel and the buoy light are electrically connected to the second power source. The solar panel can directly charge the second power source, which in turn directly powers the buoy light. This allows the buoy light to be powered independently of the first power source, facilitating uninterrupted operation of the buoy light.

[0015] As a further improvement of the above technical solution, a plurality of solar panels are hingedly connected to the top frame, and the positions of the plurality of solar panels can be adjusted so that the solar panels are better oriented toward the direction of direct sunlight, thereby improving the efficiency of solar power generation.

[0025] Reference Figure 1A marine generator includes a ballast box 100 and a wave power generation unit, wherein the ballast box 100 can be a shell with a larger weight, or a shell with a normal weight, and a ballast block can be installed inside the shell, or a ballast block can be connected to the bottom side of the shell. The ballast box 100 can stabilize the posture of the whole machine on the sea surface to prevent it from turning over. In addition, a first power supply is provided inside the ballast box 100; the wave power generation unit includes a float 210, a swing arm 220, a slide rod 230 and a rocker arm 240, one end of the swing arm 220 is rotatably connected to one side of the ballast box 100, and the swing arm 220 is connected to the rotation axis of the ballast box 100 along the horizontal direction. Extending in the direction, the float 210 is rotatably connected to the other end of the swing arm 220, and the rotation axis of the float 210 connected to the swing arm 220 is parallel to the rotation axis of the swing arm 220 connected to the counterweight box 100. The top side of the swing arm 220 protrudes upward to form a connecting chamber 221, and one end of the slide rod 230 is slidably connected to the connecting chamber 221. An electromagnetic induction device is provided between the slide rod 230 and the connecting chamber 221, and the electromagnetic induction device is electrically connected to the first power supply. One end of the rocker arm 240 is rotatably connected to the other end of the slide rod 230, and the other end of the rocker arm 240 is rotatably provided on the outside of the counterweight box 100.

[0026] As can be seen from the above, when in use, the entire offshore generator is placed on the sea surface, and the counterweight box 100 can play a major stabilizing role to prevent the overall capsizing caused by excessive waves. The float 210 floats on the water surface. When waves on the sea surface drive the float 210 to move, the float 210 swings outside the counterweight box 100 through the swing arm 220, and the slide bar 230 on the swing arm 220 and the rocker arm 240 form a connecting rod 250 mechanism. When the swing arm 220 swings, it can drive the slide bar 230 to slide relative to the connecting chamber 221, so that the electromagnetic induction device between the slide bar 230 and the connecting chamber 221 generates an induced current to charge the first power supply. In this way, the reciprocating swing of waves on the sea surface can be used to drive the slide bar 230 to slide more frequently through the float 210, which is particularly suitable for locations close to the coast and greatly improves the power generation efficiency.

[0027] In actual application, a cavity can be provided inside the connecting chamber 221 on the swing arm 220 to facilitate the installation of the electromagnetic induction device, and a connecting hole connected to the cavity is provided at the outer position of the connecting chamber 221. The sliding rod 230 is extended into the cavity through the connecting hole to realize the sliding connection between the sliding rod 230 and the connecting chamber 221. The electromagnetic induction device is mainly used to generate an induced current through the electromagnetic induction phenomenon, including a coil and a conductor. One of the coil and the conductor is installed on the sliding rod 230, and the other is installed in the connecting chamber 221. The coil and the first power supply form an electrical circuit, so that electric energy can be generated by the sliding of the sliding rod 230.

[0028] In order to buffer the sliding of the slide rod 230 relative to the connecting chamber 221, in practical applications, the slide rod 230 can be a buffer cylinder.

[0029] To improve the sliding stability of the slide bar 230, in this embodiment, the wave power generation unit further includes a restraining member connected to the bottom side of the slide bar 230. The restraining member is slidably connected to the top side of the swing arm 220 along the length of the swing arm 220. For example, a slide rail is provided on the top side of the swing arm 220, extending along the length of the swing arm 220, and the restraining member is slidably connected to the slide rail, thereby achieving sliding on the slide rail. A sliding connection is formed between the slide bar 230 and the connecting chamber 221, while another sliding connection is formed between the restraining member and the swing arm 220. This allows the slide bar 230 to slide more smoothly and stably relative to the connecting chamber 221, greatly improving the operational stability of the inductive sensing device.

[0030] To increase the range of motion of the slide bar 230, in this embodiment, the wave power generation unit further includes a connecting rod 250 disposed between the rocker arm 240 and the counterweight box 100. One end of the connecting rod 250 is rotatably connected to the end of the rocker arm 240 away from the slide bar 230, and the other end of the connecting rod 250 is rotatably connected to the outside of the counterweight box 100. The rotation axes at both ends of the connecting rod 250 are parallel to the rotation axis of the rocker arm 220 connected to the counterweight box 100. The slide bar 230 is connected to the outside of the counterweight box 100 via the rocker arm 240 and the connecting rod 250. This increases the range of motion of the rocker arm 220 driven by the float 210, thereby increasing the sliding travel of the slide bar 230 relative to the connecting chamber 221 and further improving power generation efficiency.

[0031] Furthermore, multiple wave power generation units can be arranged around the counterweight box 100. For example, the number of wave power generation units can range from four to six. The larger the counterweight box 100, the greater the number of wave power generation units. Waves impacting the counterweight box 100 from different directions can have varying degrees of impact on wave power generation units in different locations. The sliding rods 230 in the wave power generation units facing the wave impact have a greater range of motion and higher power generation efficiency. By arranging multiple wave power generation units in different directions, power generation efficiency can be further improved.

[0032] The utility model also includes a wind power generation mechanism, such as Figure 2As shown, the wind power generation mechanism includes a connecting frame 310, blades 320 and a power generation device 330. The power generation device 330 is connected to the top side of the counterweight box 100. The bottom side of the connecting frame 310 is connected to a connecting shaft 311 extending downward. The connecting shaft 311 is rotatably connected to the power generation device 330. The rotation axis of the connecting shaft 311 extends in the up and down directions. The power generation device 330 is electrically connected to the first power source. A plurality of blades 320 are connected to the connecting frame 310 around the connecting shaft 311. In actual application, the power generation device 330 is mainly used to convert the kinetic energy of the connecting shaft 311 into electrical energy. It includes a stator and a rotor. The connecting shaft 311 on the bottom side of the connecting frame 310 is connected to the rotor. By driving the rotor to rotate in the stator, mechanical energy is converted into electrical energy. The whole machine also has a wind power generation function. Specifically, the sea breeze can blow towards the blades 320, which drive the connecting frame 310 to rotate, and can drive the power generation device 330 to generate electricity and charge the first power supply, thereby further improving the power generation efficiency.

[0033] like Figure 3 As shown, the present invention further includes a solar power generation mechanism, comprising a top frame 410 and a solar panel 420. The top frame 410 is mounted on the connecting frame 310, and the solar panel 420 is mounted on the top frame 410. The solar panel 420 is electrically connected to the first power source. During use, the solar panel 420 on the top frame 410 converts solar energy into electrical energy to charge the first power source, thereby providing the entire system with solar power generation functionality and further improving overall power generation efficiency.

[0034] In the above embodiment, the top frame 410 can be directly fixed to the connecting frame 310. In this case, the solar panel 420 rotates along with the rotation of the connecting frame 310. To improve the stability of the solar panel 420 during operation, the rotation of the top frame 410 can be reduced. Specifically, the top frame 410 is rotatably connected to the top side of the connecting frame 310. For example, a bearing can be provided between the top frame 410 and the connecting frame 310. When the sea breeze blows towards the blades 320 and drives the connecting frame 310 to rotate, the rotatable connection between the top frame 410 and the connecting frame 310 can effectively reduce the phenomenon of the connecting frame 310 driving the top frame 410 to rotate, thereby improving the stability of solar charging.

[0035] In some embodiments, a buoy light 430 is connected to the top frame 410, and the first power supply is electrically connected to the buoy light 430. The buoy light 430 is powered by the first power supply, and the buoy light 430 can provide an illumination function to facilitate identification of its position in a dark environment.

[0036] The buoy light 430 can be powered directly by the first power source. When the first power source needs to be removed from the counterweight box 100 for replacement, the buoy light 430 needs to be powered off. To ensure continuous power to the buoy light 430, in this embodiment, a second power source 440 is connected to the top frame 410, and the solar panel 420 and the buoy light 430 are electrically connected to the second power source 440. The solar panel 420 can directly charge the second power source 440, which in turn directly powers the buoy light 430. This allows the power supply to the buoy light 430 to be separated from the first power source, facilitating uninterrupted operation of the buoy light 430.

[0037] Naturally, the counterweight box 100 is a detachable structure, and its structural forms are various. For example, the counterweight box 100 includes a bottom shell and a top cover. At this time, the swing arm 220 of the wave power generation unit is rotatably connected to the outside of the bottom shell, and the top cover is detachably connected to the top side of the bottom shell. For example, the top cover is connected to the top side of the bottom shell by a snap, or the top cover is fastened to the bottom shell by driving screws or bolts and other connectors. A cavity is formed between the top cover and the bottom shell, and the first power source is installed in the cavity. Structures such as counterweight blocks can also be added to the cavity to increase the weight of the counterweight box 100. In addition, in order to improve the sealing of the cavity, a sealing ring can be provided between the top cover and the bottom shell, and the top cover and the bottom shell are connected to each other through a stopper, thereby effectively reducing the infiltration of water vapor into the cavity.

[0038] The number of solar panels 420 can be one or more. To improve the working efficiency of the solar panels 420, the orientation of the solar panels 420 can be adjusted. In this embodiment, the top frame 410 is hinged with multiple solar panels 420. The positions of the multiple solar panels 420 can be adjusted so that the solar panels 420 are better oriented towards the direction of direct sunlight, thereby improving the efficiency of solar power generation. For example, if the rotation angle of the solar panels 420 cannot be automatically adjusted, the solar panels 420 can be hinged to the top frame 410 via hinges with angle positioning. Before use, the multiple solar panels 420 can be adjusted to different positions and fixed relative to each other. In this way, when the sun is at different altitudes, there is a solar panel 420 that can receive direct sunlight, thereby improving power generation efficiency. Alternatively, a motor that can drive the solar panels 420 to rotate can be provided on the top frame 410, and the motor rotates and adjusts the orientation of the solar panels 420 according to the direction of the sun, thereby further improving the working efficiency of the solar panels 420.

[0039] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
