Description

Technical Field

[0001] This utility model relates to the field of power generation device technology, specifically a wave power generation device based on a float. Background Technology

[0002] A power generation device is a complete set of equipment or systems that converts other forms of energy (such as thermal energy, mechanical energy, chemical energy, and light energy) into electrical energy. It is the core of the modern energy system and is widely used in power production, industry, transportation, and daily life.

[0003] Based on the above, the inventors have discovered the following problems: Current wave power generation devices are mainly oscillating water column power generation devices, but such power generation devices have a relatively complex structure, are difficult to maintain, have high maintenance costs, and are not convenient to use.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a wave power generation device based on a float, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a wave power generation device based on a float to solve the problems mentioned in the background art.

[0006] A wave power generation device based on a float includes an anchoring assembly. A power generation assembly is fixedly installed on the outside of the anchoring assembly. The power generation assembly includes a transducer cavity, an impeller rotatably connected inside the transducer cavity, and a generator on one side of the transducer cavity. The input end of the generator is fixedly connected to the impeller. Hydraulic pipes are connected to the top and bottom of the transducer cavity. A sliding piston is slidably connected inside the hydraulic pipe, and the hydraulic pipe is filled with hydraulic oil. A piston rod is fixedly installed on the side of the sliding piston away from the transducer cavity. Mounting strips are fixedly installed on the ends of the two piston rods away from the sliding pistons. A float is fixedly installed on one side of the mounting strip. Two one-way valves with opposite directions are fixedly installed at the connection between the hydraulic pipe and the transducer cavity. The one-way valves on the same side of the transducer cavity have the same direction.

[0007] By adopting the above technical solution, the generator input end is fixedly connected to the impeller, which facilitates the impeller to drive the generator input end to rotate, thereby converting mechanical energy into electrical energy. A sliding piston is slidably connected inside the hydraulic pipe, which allows the hydraulic pipe to limit the movement of the sliding piston, ensuring that the sliding piston can only slide up and down along the hydraulic pipe. The hydraulic pipe is filled with hydraulic oil, which allows the sliding piston to move up and down, driving the hydraulic oil to flow. A float is fixedly installed on one side of the mounting strip, which allows the wave crests and troughs to move the float up and down, thereby driving the two sliding pistons to slide up and down synchronously. The one-way valves on the same side of the transducer chamber are in the same direction, which allows the synchronous upward and downward sliding of the two sliding pistons to drive the hydraulic oil to flow. The flow of hydraulic oil drives the impeller to rotate, and the waves drive the float to move up and down, generating electrical energy. This improves power generation efficiency and has a simple structure with low maintenance costs.

[0008] Furthermore, a waterproof box is fixedly installed on one side of the transducer cavity, and a sealing ring is provided at the connection between the waterproof box and the transducer cavity. The generator is fixedly installed in the middle of the inner side of the waterproof box.

[0009] By adopting the above technical solution, a sealing ring is provided at the connection between the waterproof box and the transducer cavity, which facilitates the improvement of the sealing performance of the fixed connection between the waterproof box and the transducer cavity and avoids the waterproof box structure from being eroded by seawater.

[0010] Furthermore, mounting ears are fixedly installed at both ends of the waterproof box on the side away from the transducer cavity, and heat dissipation fins are fixedly installed in the middle of both sides of the waterproof box.

[0011] By adopting the above technical solution and setting up the heat dissipation fins, the heat dissipation effect of the waterproof box can be improved, thus preventing the generator from becoming unusable due to overheating.

[0012] Furthermore, a rectifier and an inverter are also fixedly installed inside the waterproof box, and the rectifier and inverter are electrically connected to the generator.

[0013] By adopting the above technical solution, and through the setting of rectifier and inverter, it is convenient for the rectifier to convert the electrical energy generated by the generator into stable DC power, and the inverter to convert the DC power into AC power compatible with the power grid.

[0014] Furthermore, the mooring assembly includes a float, the outer side of which is fixedly connected to a mounting lug.

[0015] By adopting the above technical solution, the device is fixedly connected to the mounting lug on the outside of the float, which facilitates the buoyancy provided by the float to float the device on the sea surface, making it convenient to install and fix the power generation components.

[0016] Furthermore, a counterweight is fixedly installed at the bottom of the float, and a protective shell is fixedly installed at the top of the float.

[0017] By adopting the above technical solution, a counterweight is fixedly installed at the bottom of the float and a protective shell is fixedly installed at the top of the float. This allows the counterweight to be held above the sea surface by gravity, and also gives the device a suitable draft, which facilitates the power generation of the power generation components.

[0018] Furthermore, a grid-connected device is fixedly installed inside the protective shell, and the grid-connected device is electrically connected to the power generation component.

[0019] By adopting the above technical solutions and setting up grid-connected equipment, it is easy to ensure that the frequency and phase of the electrical energy generated by the power generation components match the power grid.

[0020] Furthermore, a transmission cable is fixedly installed on the top of the protective shell, and the transmission cable is electrically connected to the grid-connected equipment.

[0021] By adopting the above technical solution and by setting up transmission cables, it is convenient to connect the electrical energy generated by the device into the power grid.

[0022] Furthermore, an anchor chain is fixedly installed at the bottom of the counterweight, and a fixed anchor is fixedly installed at the bottom of the anchor chain.

[0023] By adopting the above technical solution, a fixed anchor is installed at the bottom of the anchor chain, which facilitates the fixation of the device to the seabed, allows for a limited range of movement, and prevents drifting.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The generator input end is fixedly connected to the impeller, facilitating the impeller to drive the generator input end to rotate, thereby converting mechanical energy into electrical energy. A sliding piston is slidably connected inside the hydraulic pipe, allowing the hydraulic pipe to limit the movement of the sliding piston, ensuring it can only slide up and down along the hydraulic pipe. The hydraulic pipe is filled with hydraulic oil, facilitating the flow of hydraulic oil as the sliding piston moves up and down. A float is fixedly installed on one side of the mounting strip, allowing the wave crests and troughs to move the float up and down, thus driving the two sliding pistons to slide up and down synchronously. The one-way valves on the same side of the transducer chamber are aligned, ensuring that the synchronous upward and downward sliding of the two sliding pistons both drive the flow of hydraulic oil. This hydraulic oil flow drives the impeller to rotate, and the wave-driven float movement generates electrical energy. This improves power generation efficiency, and the structure is simple with low maintenance costs. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: a wave power generation device based on a float, including an anchor assembly 101, a power generation assembly 102 fixedly installed on the outside of the anchor assembly 101, the power generation assembly 102 including a transducer cavity 10202, an impeller 10209 rotatably connected inside the transducer cavity 10202, a generator 10208 provided on one side of the transducer cavity 10202, the input end of the generator 10208 being fixedly connected to the impeller 10209, and the fixed connection between the input end of the generator 10208 and the impeller 10209 facilitating the impeller 10209 to drive the generator 10209. The input end rotates, thus converting mechanical energy into electrical energy. Hydraulic pipes 10203 are connected to both the top and bottom of the transducer cavity 10202. A sliding piston 10204 is slidably connected inside the hydraulic pipe 10203. This slidable connection allows the hydraulic pipe 10203 to limit the movement of the sliding piston 10204, ensuring that the piston can only slide up and down along the hydraulic pipe 10203. The hydraulic pipe 10203 is filled with hydraulic oil, which facilitates sliding... The up-and-down sliding of piston 10204 drives the flow of hydraulic oil. A piston rod 10205 is fixedly installed on the side of the sliding piston 10204 away from the transducer chamber 10202. An installation strip 10206 is fixedly installed on the end of each piston rod 10205 away from the sliding piston 10204. A float 10207 is fixedly installed on one side of the installation strip 10206. The float 10207, fixedly installed on one side of the installation strip 10206, allows the wave crests and troughs to move the float 10207 up and down, thereby causing the two sliding pistons 10204 to slide up and down synchronously. Hydraulic pipe 1... Two one-way valves 10212 with opposite directions are fixedly installed at the connection between 0203 and the transducer cavity 10202. The one-way valves 10212 on the same side of the transducer cavity 10202 have the same direction. The fact that the one-way valves 10212 on the same side of the transducer cavity 10202 have the same direction makes it easy for the two sliding pistons 10204 to slide synchronously upward and downward, which can drive the hydraulic oil to flow. The flow of hydraulic oil drives the impeller 10209 to rotate, which in turn causes the wave to drive the float 10207 to move up and down, generating electrical energy. This is beneficial to improving power generation efficiency, and the structure is simple and the maintenance cost is low.

[0033] A waterproof box 10201 is fixedly installed on one side of the transducer cavity 10202. A sealing ring is provided at the connection between the waterproof box 10201 and the transducer cavity 10202. The generator 10208 is fixedly installed in the middle of the inner side of the waterproof box 10201. The sealing ring at the connection between the waterproof box 10201 and the transducer cavity 10202 is provided to improve the sealing performance of the fixed connection between the waterproof box 10201 and the transducer cavity 10202 and prevent the structure of the waterproof box 10201 from being corroded by seawater.

[0034] The waterproof box 10201 has mounting ears 10210 fixedly installed at both ends on the side away from the transducer cavity 10202, and heat dissipation fins 10211 fixedly installed in the middle of both sides of the waterproof box 10201. The setting of the heat dissipation fins 10211 facilitates the setting of the heat dissipation fins 10211, which helps to improve the heat dissipation effect of the waterproof box 10201 and prevents the generator 10208 from becoming unusable due to excessive temperature.

[0035] The waterproof box 10201 also has a rectifier and an inverter fixedly installed inside, and the rectifier and inverter are electrically connected to the generator 10208. The rectifier and inverter facilitate the rectifier to convert the electrical energy generated by the generator 10208 into stable DC power, and the inverter to convert the DC power into AC power compatible with the power grid.

[0036] The mooring assembly 101 includes a float 10101, the outer side of which is fixedly connected to a mounting lug 10210. The fixed connection between the outer side of the float 10101 and the mounting lug 10210 facilitates the float 10101 to provide buoyancy to float the device on the sea surface, thus facilitating the installation and fixation of the power generation assembly 102.

[0037] The float 10101 has a counterweight 10104 fixedly installed at its bottom and a protective shell 10102 fixedly installed at its top. The counterweight 10104 fixedly installed at the bottom and the protective shell 10102 fixedly installed at the top of the float 10101 ensures that the protective shell 10102 is always kept above the sea surface by the counterweight 10104 under the action of gravity, and that the device has a suitable draft, which facilitates the power generation component 102 to generate electricity.

[0038] The protective shell 10102 has a grid-connected device fixedly installed inside. The grid-connected device is electrically connected to the power generation component 102. The grid-connected device helps to ensure that the frequency and phase of the electrical energy generated by the power generation component 102 are matched with the power grid.

[0039] The protective shell 10102 has a transmission cable 10103 fixedly installed on its top. The transmission cable 10103 is electrically connected to the grid-connected equipment. The installation of the transmission cable 10103 facilitates the connection of the electrical energy generated by the device into the power grid.

[0040] The counterweight 10104 has an anchor chain 10105 fixedly installed at its bottom, and a fixed anchor 10106 is fixedly installed at its bottom. The fixed anchor 10106 at the bottom of the anchor chain 10105 facilitates the fixation of the device to the seabed, allows for a limited range of movement, and prevents drifting.

[0041] Specifically, the working principle of this float-based wave power generation device is as follows: During use, a fixed anchor 10106 is fixedly installed at the bottom of the anchor chain 10105, facilitating the fixation of the device to the seabed, allowing a limited range of movement and preventing drift. The float 10101 is fixedly connected to the mounting lug 10210 on its outer side, allowing the float 10101 to provide buoyancy and float the device on the sea surface, facilitating the installation and fixation of the power generation component 102. A counterweight 10104 is fixedly installed at the bottom of the float 10101, and a protective device is fixedly installed at the top of the float 10101. The shell 10102 ensures that the counterweight 10104, under the influence of gravity, keeps the protective shell 10102 above the sea surface and provides the device with a suitable draft, facilitating the generation of the power generation component 102. The input end of the generator 10208 is fixedly connected to the impeller 10209, allowing the impeller 10209 to drive the input end of the generator 10208 to rotate, thereby converting mechanical energy into electrical energy. A sliding piston 10204 is slidably connected inside the hydraulic pipe 10203, allowing the hydraulic pipe 10203 to limit the movement of the sliding piston 10204. The position allows the sliding piston 10204 to slide only up and down along the hydraulic pipe 10203. The hydraulic pipe 10203 is filled with hydraulic oil, which facilitates the flow of hydraulic oil as the sliding piston 10204 moves up and down. A float 10207 is fixedly installed on one side of the mounting strip 10206, allowing the wave crests and troughs to move the float 10207 up and down, thus causing the two sliding pistons 10204 to slide synchronously up and down. The one-way valves 10212 on the same side of the transducer chamber 10202 are in the same direction, facilitating the movement of the two sliding pistons 10204. Both synchronous upward and downward sliding of component 4 can drive the flow of hydraulic oil, which in turn drives the impeller 10209 to rotate. This allows the wave-driven float to move up and down, generating electrical energy. This improves power generation efficiency and features a simple structure with low maintenance costs. The rectifier and inverter facilitate the conversion of the electrical energy generated by generator 10208 into stable DC power, while the inverter converts the DC power into grid-compatible AC power. The grid connection equipment ensures that the frequency and phase of the electrical energy generated by generator component 102 match the grid.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
