Description

Technical Field

[0001] This invention relates to the field of renewable energy technology, specifically to a high-efficiency energy storage system and method for wind power generation. Background Technology

[0002] Wind power generation, belonging to the field of renewable energy, is a technology that uses wind energy to generate electricity. Wind power generation converts mechanical energy into electrical energy by rotating a turbine generator within a wind turbine. Wind power is a clean and sustainable form of energy, producing no greenhouse gas emissions or pollutants, making it environmentally friendly. The wind turbine unit uses an automatic control system to adjust its rotation according to wind speed and direction, and transmits the generated electricity to the power grid or user terminals via cables. Wind power can be used to supply power systems, industrial enterprises, rural areas, and urban buildings, among other applications.

[0003] High-efficiency energy storage systems for wind power generation can help solve the intermittency and instability issues of wind power generation. These systems include battery energy storage, compressed air energy storage, and water pump energy storage. The working principle of a wind power battery energy storage system is to convert the electrical energy generated by the wind turbine into direct current and store it in batteries for later use. However, different types of batteries have a fixed lifespan, typically between a few years and a dozen years. After exceeding this lifespan, battery performance deteriorates, capacity decreases, and cycle charge / discharge efficiency declines, leading to insufficient battery capacity to meet demand. Long-term use also results in capacity decay and increased internal resistance, further reducing energy storage capacity and affecting the stability and reliability of the system.

[0004] Patent application number 202222577275.4 discloses an energy storage device based on new energy photovoltaic and wind power generation, which stores the electrical energy generated by wind power generation by setting up multiple batteries inside the control room.

The first charging head and the second charging head are installed on the two electrodes of the cylindrical battery.

[0025] 5) The output DC power is then inverted by the power regulating device to become AC power that meets the power demand. The output AC power enters the power grid or is supplied to equipment that needs power for actual energy supply.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention, by setting up an installation mechanism, can install and fix multiple energy storage devices. The installation mechanism includes a circular tube with a support frame inside for reinforcement. The circular tube is fixed to the frame through multiple connecting plates to achieve a stable connection of the frame. The frame is provided with an installation compartment that can accommodate the energy storage devices. After the energy storage devices are installed inside the installation compartment, the installation compartment protects the energy storage devices from damage. The maintenance opening on the front of the installation compartment allows staff to easily remove the cylindrical batteries.

[0028] 2. By setting up an energy storage mechanism, the present invention can store the electrical energy generated by wind power generation. The power generated by wind power generation is rectified by the converter and converted into DC power and transmitted to the charging controller. The charging controller can adjust the frequency, voltage and other parameters of the power to meet the charging requirements of the cylindrical battery, and charge the cylindrical battery through the first charging head and the second charging head.

[0029] 3. This invention, by incorporating a fire extinguishing mechanism, can rapidly extinguish fires in the event of spontaneous combustion of a cylindrical battery. A smoke sensor detects the smoke concentration inside the mounting compartment, and the detection signal is transmitted to the controller. When the smoke concentration is too high, indicating that the cylindrical battery is burning, the solenoid valve is activated. The high-pressure liquid carbon dioxide inside the carbon dioxide tank comes into contact with the air and vaporizes. The vaporized carbon dioxide enters the inner cavity of the outer casing and enters the mounting compartment through the vent on the inner casing. It comes into contact with the burning cylindrical battery inside the mounting compartment. When the carbon dioxide comes into contact with the flame, it disperses and absorbs the heat around the flame, and at the same time reacts with the oxygen in the flame to form a gas convection layer, effectively isolating the flame from the oxygen. This reduces the oxygen required for the flame, causing the flame to gradually extinguish, thus achieving automatic fire extinguishing of the cylindrical battery and increasing the safety of the energy storage system.

[0030] 4. By setting up a support mechanism, the present invention can support and fix the installation mechanism, energy storage mechanism and fire extinguishing mechanism. The support component is installed at the bottom of the outer shell to support and fix the fire extinguishing mechanism. The support component is reinforced with reinforcing ribs inside. The mounting seat at the bottom of the support component can install the support component on a cement foundation. Attached Figure Description

[0047] Please see Figures 1-4 and Figures 7-9 A high-efficiency energy storage system for wind power generation includes an installation mechanism 1 and an energy storage mechanism 2. The energy storage mechanism 2 is fixedly connected inside the installation mechanism 1. There are several energy storage mechanisms 2 distributed around the surface of the installation mechanism 1. The energy storage mechanism 2 stores energy generated by wind power generation.

[0048] Furthermore, the installation mechanism 1 includes a circular tube 101, with a support frame 102 fixedly connected to the inner wall of the circular tube 101. The support frame 102 reinforces the circular tube 101. A connecting plate 103 is fixedly connected to the surface of the circular tube 101, and a frame 105 is fixedly connected to one side of the connecting plate 103. The circular tube 101 is fixed to the frame 105 through multiple connecting plates 103 to achieve a stable connection of the frame 105.

[0049] Furthermore, several installation compartments 104 for use with the energy storage mechanism 2 are fixedly connected to the surface of the frame 105. After the energy storage mechanism 2 is installed inside the installation compartment 104, the installation compartment 104 protects the energy storage mechanism 2 from damage. The front of the installation compartment 104 has an opening for maintenance, which makes it easy for staff to remove the cylindrical battery 204. The surface of the installation compartment 104 has an air inlet for carbon dioxide to enter. The carbon dioxide entering the installation compartment 104 can extinguish the fire in the cylindrical battery 204.

[0050] Furthermore, the energy storage mechanism 2 includes a housing 201, with a cover 209 rotatably connected to the inner wall of the housing 201. A base 207 is fixedly connected to the bottom of the housing 201, and the bottom of the base 207 is fixedly connected to the inner wall of the installation chamber 104 to fix the energy storage mechanism 2. A smoke sensor 208 is fixedly installed on the front of the base 207. The smoke sensor 208 detects the smoke concentration inside the installation chamber 104, and the detection signal is transmitted to the controller 5. When the smoke concentration is too high, it indicates that the cylindrical battery 204 is burning. A battery limiting bracket 211 is movably connected to the inner wall of the housing 201, and a cylindrical battery 204 is movably connected to the top of the battery limiting bracket 211. The battery limiting bracket 211 limits the cylindrical battery 204. Handles 220 are fixedly connected to both the left and right sides of the cylindrical battery 204.

[0051] Furthermore, a sliding seat 219 is fixedly connected to the bottom of the battery limiting bracket 211, and a slide rail 218 is movably connected to the surface of the sliding seat 219. The bottom of the slide rail 218 is fixedly connected to the bottom of the inner wall of the base 207. When the battery limiting bracket 211 moves, it drives the sliding seat 219 to slide on the inner wall of the slide rail 218. The sliding seat 219 and the slide rail 218 limit the battery limiting bracket 211 to prevent it from shaking during movement.

[0052] Furthermore, a first charging head 202 is fixedly connected to the rear side of the inner wall of the box 201, and a second charging head 221 is fixedly connected to the rear side of the box cover 209. A cable 203 is electrically connected to the first charging head 202 and the second charging head 221. The cable 203 electrically connects the first charging head 202 and the second charging head 221. A charging controller 222 is fixedly installed on the rear side of the first charging head 202. The charging controller 222 is electrically connected to the first charging head 202. The power generated by wind power generation is rectified by the converter and converted into DC power and transmitted to the charging controller 222. The charging controller 222 can adjust the frequency, voltage and other parameters of the power to meet the charging requirements of the cylindrical battery 204, and charge the cylindrical battery 204 through the first charging head 202 and the second charging head 221.

[0053] Furthermore, a first belt drive structure 206 and a second belt drive structure 210 are fixedly fitted on the left and right sides of the box cover 209, respectively. A micro reduction motor 205 is fixedly connected to the left side of the box body 201. The output shaft of the micro reduction motor 205 is fixedly connected to the transmission end of the first belt drive structure 206. A large gear 214 is rotatably connected to the right side of the box body 201. The large gear 214 is fixedly connected to the transmission end of the second belt drive structure 210 through a rotating shaft. A small gear 213 meshes with the bottom of the large gear 214. A connector 212 is rotatably connected to the right side of both the large gear 214 and the small gear 213. The connector 212 is fixedly connected to the right side of the box body 201. A rotating rod 216 is fixedly connected to the inner wall of the small gear 213. A drive gear 217 is fixedly fitted on the surface of the rotating rod 216. A rack 215 meshes with the top of the drive gear 217. The rack 215 is fixedly connected to the bottom of the battery limiting frame 211.

[0054] Specifically, when the cylindrical battery 204 needs to be removed for maintenance, the output shaft of the first belt drive structure 206 drives the first belt drive structure 206 to work. The first belt drive structure 206 drives the cover 209 to rotate slowly forward, causing the cover 209 to open automatically. During the opening of the cover 209, the second belt drive structure 210 is simultaneously driven to work. The second belt drive structure 210 drives the large gear 214 to rotate. The large gear 214 drives the small gear 213 that meshes with it to rotate. The rotating rod 216 drives the drive gear 217 to rotate, which in turn drives the rack 215 to move forward. The rack 215 drives the battery limiting bracket 211 to slide forward on the inner wall of the box 201, causing the battery limiting bracket 211 to drive the cylindrical battery 204 forward, pushing the front end of the cylindrical battery 204 out of the inner cavity of the box 201. This makes it easier for staff to quickly remove the cylindrical battery 204 from the top of the battery limiting bracket 211 using the handle 220, increasing the efficiency of the inspection and maintenance of the cylindrical battery 204. Example

[0055] As a second embodiment of the present invention, this embodiment is based on the previous embodiment; please refer to [link to previous embodiment]. Figures 5-6 A high-efficiency energy storage system for wind power generation also includes a fire extinguishing mechanism 3, a support mechanism 4, and a controller 5. The fire extinguishing mechanism 3 is fixedly sleeved on the surface of the installation mechanism 1 to extinguish fires in the energy storage mechanism 2. The support mechanism 4 is fixedly connected to the bottom of the fire extinguishing mechanism 3 to support it. The controller 5 is fixedly installed on the surface of the fire extinguishing mechanism 3.

[0056] Furthermore, the fire extinguishing mechanism 3 includes an outer shell 301 and an inner shell 305. The outer shell 301 is fixedly connected to the surface of the inner shell 305. The inner shell 305 has several air vents 306. The inner shell 305 is fixedly sleeved on the surface of the frame 105 and the installation chamber 104, thereby fixing the installation mechanism 1.

[0057] Furthermore, a solenoid valve 303 is connected to the top of the outer casing 301, and a carbon dioxide tank 302 is connected to the top of the solenoid valve 303. Tank legs 304 are fixedly fitted at both ends of the carbon dioxide tank 302. The bottom of the tank legs 304 is fixedly connected to the top of the outer casing 301. When the cylindrical battery 204 burns, the controller 5 opens the solenoid valve 303. The high-pressure liquid carbon dioxide inside the carbon dioxide tank 302 comes into contact with the air and vaporizes. The vaporized carbon dioxide enters the inner cavity of the outer casing 301 and enters the installation chamber 104 through the vent 306 on the inner casing 305. It comes into contact with the cylindrical battery 204 burning inside the installation chamber 104. When the carbon dioxide comes into contact with the flame, it disperses and absorbs the heat around the flame. At the same time, it reacts with the oxygen in the flame to form a gas convection layer, which effectively isolates the flame from the oxygen. This reduces the oxygen required by the flame and causes the flame to gradually extinguish, thereby achieving automatic fire extinguishing of the cylindrical battery 204 and increasing the safety of the energy storage system.

[0058] Furthermore, the support mechanism 4 includes a support member 401, which is installed on the bottom of the outer shell 301 to support and fix the fire extinguishing mechanism 3. The bottom of the support member 401 is fixedly connected to a mounting base 402. Reinforcing ribs 403 are fixedly connected to both sides of the inner wall of the support member 401. The reinforcing ribs 403 strengthen the support member 401. The bottom of the mounting base 402 is fixedly connected to an anti-slip pad made of rubber to increase the friction at the bottom of the mounting base 402. The top of the support member 401 is fixedly connected to the bottom of the outer shell 301. The support member 401 can be installed on a cement foundation through the mounting base 402. Specifically, expansion bolts are passed through the mounting base 402 and nailed into the cement foundation. Example

[0060] 1) Wind turbine generator sets use wind power to drive the generator rotor to rotate, converting mechanical energy into electrical energy. The generator then rectifies the generated alternating current through a converter, converting it into direct current.

[0061] 2) DC power is connected to the charging controller 222 via wires. The charging controller 222 adjusts the frequency, voltage and other parameters of the power to meet the charging requirements of the cylindrical battery 204, and charges the cylindrical battery 204 through the first charging head 202, cable 203 and the second charging head 221. The first charging head 202 and the second charging head 221 are installed on the two electrodes of the cylindrical battery 204.

[0062] 3) The adjusted DC power enters the battery, and due to the chemical reaction inside the battery, the electrical energy is converted into chemical energy and stored.

[0063] 4) When energy needs to be released, the cylindrical battery 204 is controlled by the charging controller 222 to output current and voltage, and the stored chemical energy is converted back into electrical energy.

[0064] 5) The output DC power is then inverted by the power regulating device to become AC power that meets the power demand. The output AC power enters the power grid or is supplied to equipment that needs power for actual energy supply.
