Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power generation, in particular to a wind power generation equipment based on zero-carbon environmental protection. BACKGROUND

[0002] Wind power generation does not burn fossil fuels, does not emit waste gas and waste water during operation, and belongs to the energy form of "zero emission and zero pollution". It can directly replace traditional power grid high-carbon power sources such as coal, oil and gas, and achieve substantial reduction of carbon emissions. In response to the development trend of combining zero-carbon environmental protection with lightweight materials, more and more wind power generation equipment begins to use recyclable composite materials such as low-carbon steel and recycled aluminum, and the blades also use bio-based resin or degradable composite materials for recycling and reuse. For example, a tree-shaped wind power generation equipment is provided. A plurality of tulip-shaped power generation modules are installed on the biomimetic tree, and the power generation blades use bio-based resin blade materials, which are environmentally friendly and aesthetically pleasing, can supply power to the city, and can also harmonize with the natural environment, providing an innovative path for the city's zero-carbon energy system that combines functionality and aesthetics. However, a large number of bio-based resin blades are used on the "one" tree-shaped wind power generation equipment. The wear resistance and structural impact strength of the blades made of this material are much lower than those made of metal materials. In strong wind weather, there is a risk that a large number of bio-based resin blades will be scratched or even damaged by hard foreign objects in the strong wind. Moreover, the bio-based resin blades are relatively light in weight, and the speed of the bio-based resin blades rotating under the action of external wind is faster. When the external wind causes the bio-based resin blades to rotate at too high a speed, the electric energy rotating ring module connected to the bio-based resin blades is prone to overload power generation and damage.

[0019] As Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the trunk bionic frame 11 is fixedly connected with a water storage tank 4; the water storage tank 4 is connected with a water inlet pipe 41, and the water inlet pipe 41 is connected with a water conveying pipeline; the outer surface of the buried energy storage module 3 is provided with a heat medium conveying pipeline 31; the water storage tank 4 is provided with a micro pump 32, and the buried energy storage module 3 supplies power to the micro pump 32; one end of the heat medium conveying pipeline 31 is connected to the output port of the micro pump 32, and the other end is connected to the water storage tank 4; the outer surface of the buried energy storage module 3 is provided with a plurality of vapor chamber plates 33; all the vapor chamber plates 33 are connected to the heat medium conveying pipeline 31; each protection sleeve 13 is fixedly connected with an annular nozzle 44, and the nozzle of the annular nozzle 44 is inclined upward and faces the corresponding wind blade 23; the pull rod 16 is provided in a hollow pipe structure; each annular nozzle 44 and the hollow pipe structure of the pull rod 16 are connected with a shunt pipe 45; the water storage tank 4 is provided with a pressurizing pump 42, and the buried energy storage module 3 supplies power to the pressurizing pump 42; the output port of the pressurizing pump 42 is connected to the hollow pipe structure of the pull rod 16 through a flexible hose; the water storage tank 4 is provided with an electric heater 43, and the buried energy storage module 3 supplies power to the electric heater 43.

[0020] In the conventional power generation of the wind power generation equipment based on zero-carbon environmental protection, the trunk bionic frame 11 is fixed on the ground, the buried energy storage module 3 is buried below the ground, and the wind blades 23 are all in a state of completely exposing the protection sleeves 13 upward. The external wind flow drives the wind blades 23 to rotate, the wind blades 23 drive the rotating shaft 22 on the electric energy rotating ring module 21 to generate electricity, the electric energy rotating ring module 21 transmits power to the buried energy storage module 3 through the power transmission module, and when the external circuit system needs power, the buried energy storage module 3 outputs the energy storage power to the external circuit system. The buffer lining 24 in the wind blade 23 can buffer and intercept hard foreign matters impacted by the airflow.

[0021] The external water conveying pipeline conveys water flow into the water storage tank 4 through the water inlet pipe 41. When the external environment temperature is higher than 40℃, the micro pump 32 regularly conveys the water flow in the water storage tank 4 to the heat medium conveying pipeline 31. The water flow flows along the heat medium conveying pipeline 31 around the outer surface of the buried energy storage module 3 for one round and then flows back to the water storage tank 4, so as to realize the water cooling and temperature reduction of the outer surface of the buried energy storage module 3 by the water flow in the heat medium conveying pipeline 31 cooperating with the vapor chamber plates 33. The pressurizing pump 42 can also regularly convey the water flow in the water storage tank 4 to the hollow pipe structure of the pull rod 16. The water flow is conveyed to the annular nozzle 44 along the hollow pipe structure of the pull rod 16 and the shunt pipe 45. The water flow is sprayed towards the wind blade 23 through the annular nozzle 44. The water flow can wash off the dust adhered to the surface of the wind blade 23, so as to ensure the stable operation of the buried energy storage module 3 and the wind blade 23. When the water flow flows downward along the wind blade 23 and passes through the electric energy rotating ring module 21, the water cooling and temperature reduction of the electric energy rotating ring module 21 can also be realized.

[0022] When the ambient temperature is lower than 4℃, the electric heater 43 heats the water flow in the water storage tank 4, the micro pump 32 sends the heated water flow in the water storage tank 4 to the heat medium conveying pipeline 31 at regular time, the water flow flowing in the heat medium conveying pipeline 31 cooperates with the heat plate 33 to heat and insulate the outer surface of the buried energy storage module 3, and the pressurizing pump 42 also sends the heated water flow to the annular spray pipe 44 at regular time, the heated water flow is sprayed to the surface of the wind blade 23 through the annular spray pipe 44 to heat and deice, so that the buried energy storage module 3 and the wind blade 23 can operate stably.

[0023] In the strong wind power generation of the wind power generation equipment based on zero-carbon environmental protection, the speed of the rotating shaft 22 driven by the wind blade 23 blown by the strong wind flow is accelerated, when the electric energy rotating ring module 21 identifies that the speed of the rotating shaft 22 exceeds the maximum allowable rotating speed, the electric push rod 17 pulls the pull rod 16 to move downward, the pull rod 16 pulls the pull rope 18 to drive the lifting block 14 to move downward along the protection sleeve 13, the lifting block 14 drives the lower side area of the wind blade 23 of the small tulip-shaped power generation module to be retracted into the protection sleeve 13, when the electric energy rotating ring module 21 detects that the rotating speed of the rotating shaft 22 exceeds the maximum allowable value, the control system starts the electric push rod 17, the higher the detected rotating speed is, the greater the downward stroke of the electric push rod 17 is, so that the lifting block 14 drives more parts of the wind blade 23 to be retracted into the protection sleeve 13, which can reduce the area of the wind blade 23 exposed to the strong wind flow and contacted with the strong wind flow, so as to reduce the speed of the rotating shaft 22 driven by the wind blade 23, keep the rotating speed of the rotating shaft 22 less than the maximum allowable rotating speed, avoid the overloading power generation damage of the electric energy rotating ring module 21 caused by the high rotating speed, and most parts of the wind blade 23 are protected in the protection sleeve 13, so that the scratching and damage of the wind blade 23 caused by the hard foreign matters mixed in the strong wind flow can be reduced.

[0024] Example 2, as Figures 1-6As shown, based on the above embodiment 1, each protective sleeve 13 in this embodiment is fixed with a protective net 19, and the protective net 19 is located in the lower area of ​​the corresponding wind turbine blade 23. During normal power generation, when the wind turbine blade 23 drives the rotating shaft 22 on the power transmission module 21 to generate electricity, the protective net 19 is located in the lower area of ​​the wind turbine blade 23 and will not interfere with the external wind flow blowing the wind turbine blade 23. During strong wind power generation, most of the area of ​​the wind turbine blade 23 is contained in the protective sleeve 13, and only a small part of the upper part of the wind turbine blade 23 is exposed from the protective sleeve 13. This exposed part of the wind turbine blade 23 is protected in the protective net 19. The protective net 19 can not only weaken the impact of strong wind blowing towards the wind turbine blade 23, but also intercept hard foreign objects mixed in the strong wind, thus enhancing the protection effect of the wind turbine blade 23.

[0025] Example 3, as Figures 1-6 As shown, based on the above embodiment 2, each protective sleeve 13 in this embodiment is equipped with an LED light 5. The LED light 5 is electrically connected to the power transmission module of the corresponding power transfer module 21. When the wind turbine blade 23 drives the rotating shaft 22 on the power transfer module 21 to generate electricity, a small portion of the electrical energy output from the power transmission module of the power transfer module 21 is sent to the corresponding LED light 5, and the LED light 5 is lit up. The greater the power generation generated by the wind turbine blade 23 driving the rotating shaft 22, the brighter the LED light 5. The lighting status of the LED light 5 can be used to determine whether the power transfer module 21 is in normal working condition.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
