Description

Technical fields:

[0001] This invention relates to the field of power generation devices, and in particular to a platform-type wave power generation device. Background technology:

[0002] Ocean waves are the undulating phenomena of seawater. Due to the slope and complex topography of the seabed in nearshore waters, deep-sea swells are broken down into horizontal and vertical water movements. The crest of each wave forms a current moving towards the shore, while the trough forms a current moving backward. When adjacent advancing and retreating waves meet, they "synthesize" into exaggerated, never-repeating "waves," whose size, length, and position are all unique. Therefore, the common sayings "waves rise even without wind" and "three-foot waves even without wind" are not wrong; in fact, waves will appear at sea regardless of whether there is wind or not.

[0003] Wave power generation has become one of the main channels for developing and utilizing renewable energy, following wind and solar power. Wave power plants can fully utilize the advantages of coastlines and abundant sunshine to develop renewable energy. Unlike wind power, although both are renewable and clean natural energy sources, wave power generation differs significantly in their output. First, both are located in fixed positions. While wind and waves vary in strength, wind is generally weaker, while waves are almost constant. Although waves are also affected by wind, wave power generation produces a greater output for the same amount of energy. However, traditional wave power plants are complex in structure, cumbersome to install, and have high costs. Summary of the Invention:

[0004] In view of this, it is necessary to provide a platform-type wave power generation device.

[0005] A platform-type wave power generation device includes a support platform, support columns, a conversion component, a float assembly, an energy storage component, a gearbox, and a generator. The support platform is equipped with support columns at its four bottom corners. The conversion component is fixedly mounted on the bottom of the support platform. The float assembly is mounted on the conversion component. The conversion component is mounted in conjunction with the energy storage component. The energy storage component, gearbox, and generator are fixed on the support platform. The output end of the energy storage component is mounted in conjunction with the gearbox, and the output end of the gearbox is mounted in conjunction with the generator.

[0006] Preferably, the conversion assembly includes a rack-shaped conversion plate, a first piston cylinder, a hydraulic connector, fastening screws, a connecting plate, and a guide plate. The rack-shaped conversion plate is located at the bottom of the support platform, and there are at least two rack-shaped conversion plates. Several first piston cylinders are mounted on one side of the rack-shaped conversion plate. The rack-shaped conversion plate is equipped with a number of hydraulic connectors equal to the number of first piston cylinders. The hydraulic connectors are connected to the first piston cylinders one by one. The two sides of the rack-shaped conversion plate are equipped with connecting plates by fastening screws. A guide plate is fixedly mounted on one end of the connecting plate, and a guide rail is opened on the inner side of the guide plate.

[0007] Preferably, the connecting plates are arranged in pairs, and the number of pairs is not less than two.

[0008] Preferably, the float assembly includes a float, a lifting rod, a connecting arm, a support shaft, and a sprocket. The upper part of the float is fixedly connected to the lifting rod, and two connecting arms are fixedly mounted on the lifting rod. One end of each connecting arm is fitted with a support shaft, and a sprocket is mounted on the support shaft. The sprocket is located in the middle of the connecting arm and can contact the first piston cylinder.

[0009] Preferably, the energy storage assembly includes a base, a main bearing, a rotating shaft, a steel sleeve, second piston cylinders, a force transmission assembly, and a one-way ratchet. Two bases are fixedly mounted on the support platform, a main bearing is fixedly mounted on the base, a rotating shaft is mounted on the two main bearings, and a one-way ratchet is fixedly mounted on the rotating shaft. The steel sleeve is fixedly mounted between the two bases via a base, and is fitted over the one-way ratchet and fitted with the rotating shaft. A plurality of second piston cylinders are fixedly mounted on the steel sleeve, and the second piston cylinders are connected to the hydraulic joints one-to-one via pipes. The inner wall of the steel sleeve is fitted with a number of force transmission assemblies equal to the number of second piston cylinders. The force transmission assemblies can contact the one-way ratchet. One end of the rotating shaft is connected to the input end of the transmission.

[0010] Preferably, the force transmission assembly includes connecting screws, a base plate, a sleeve, a telescopic block, a push rod, and a return spring. The base plate is mounted on the inner wall of the steel sleeve by two connecting screws. The sleeve is mounted on the base, and the telescopic block is mounted inside the sleeve. One end of the telescopic block is connected to the push rod, and one end of the push rod can contact one end of the second piston cylinder. The return spring is located inside the sleeve, with one end mounted to the base plate and the other end connected to the telescopic block.

[0011] This invention provides a platform-type wave power generation device, in which a float moves up and down under the action of waves, driving a sprocket to rise and fall during the movement. When the sprocket rises and falls, it contacts a first piston cylinder, which is compressed by pressure and transmits the pressure to hydraulic oil. This hydraulic oil is then connected to a second piston cylinder via a hydraulic connector and pipeline. The second piston cylinder transmits the hydraulic pressure to a force transmission component, which can contact a one-way ratchet to convert the hydraulic pressure into power, causing the rotating shaft to rotate. The rotational power is then transmitted to a generator via a gearbox. The number of first and second piston cylinders corresponds one-to-one, thus generating intermittent power to store energy for power generation. The device has a simple structure, low cost, and high power generation efficiency. Attached image description:
