Description

Technical Field

[0001] The invention belongs to the technical field of wind power generation, and in particular relates to an adaptive wind gathering and unloading dual-purpose module capacity-increasing wind power generation system. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind is a pollution-free energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries are paying more attention to wind power generation. Wind power generation is one of the most environmentally friendly power generation technologies and has been widely promoted. The relevant technology has gradually matured.

[0003] The device required for wind power generation is called a wind turbine. This type of wind turbine can be roughly divided into three parts: wind blades, generators, and towers. At present, wind power is mainly based on open three-blade wind power generation systems. However, there are the following problems:

[0004] (1) Unstable power generation efficiency: Since wind speed and wind direction are constantly changing during the actual power generation process, the power generation efficiency will be greatly reduced once they change. Sometimes there will be insufficient wind and power generation will not be possible, resulting in power generation failure in light wind conditions and voltage instability due to wind speed changes. Unfavorable factors such as high and low frequency, high noise, and wind abandonment will affect the cost-effectiveness of the wind turbine generator set.

[0005] (2) Blades are easily damaged: When the wind blades of a wind turbine are subjected to a strong wind with a cut-out wind speed of more than 25 m / s, the wind turbine will self-lock and shut down to avoid the risk of self-destruction due to overspeed. However, the wind blades are damaged because the bending moment, torque, shear strength and extrusion strength that the roots can withstand are limited. In severe cases, the entire wind blade may fly out.

[0006] (3) Noise hazard: When the long wind blades rotate, their noise is inevitable. The noise of wind blades can be roughly divided into three categories: (a) thickness noise, which is caused by the compression of air and wind blades; (b) load noise, which is caused by the large load on the wind blades; (c) impulse noise, which is generated when the Mach number is close to 1. Therefore, the impact of noise on the environment cannot be ignored;

[0007] (4) Air pollution: A vortex is easily formed in a certain range around the running wind turbine blades, causing smoke and dust to accumulate and PM2.5 to exceed the standard, seriously affecting the surrounding environment;

[0008] (5) Limited application: As high-quality wind resources are gradually being developed and exhausted, wind turbines have to be deployed in areas with increasingly poor wind resource conditions. In order to obtain economic benefits from investment, towers are constantly being raised and the capacity of wind turbines is constantly increasing, thus severely limiting the installation area. Summary of the invention

[0009] In view of the shortcomings of the prior art, the present invention provides a wind power generation system with an adaptive wind gathering and wind unloading dual-purpose module capacity expansion type. In an environment with good wind resources, the power generation capacity can be made into an ultra-large independent power supply unit to supply power to towns, factories, hospitals, communications and other systems nearby, thereby reducing the cost of power transmission and transformation and avoiding social disorder caused by large-scale power outages after failures in distant power supply hubs. This technology is suitable for installation on rooftops as small as enterprises and institutions, as well as open areas, to meet the power demand of the installed enterprises or institutions themselves or the entire park.

[0050] In a specific embodiment, the distal edge of the blade 332 is processed into a wave-like shape to reduce noise impact.

[0051] In a specific embodiment, in the gathering and unloading conversion mechanism 4, the above-mentioned wind collecting mechanism can be additionally provided at a spacing position formed between the two inner end partitions 422a and 422b, so that when the wind force is strong, the wind force unloaded from the unloading port can be reused for a second time, thereby increasing the power generation efficiency.

[0053] In a specific embodiment, the wind collecting hood 2, the wind collecting mechanism 3 and the three sets of collecting and unloading conversion mechanisms 4 constitute a wind turbine generator set, which is provided with multiple ones and are stacked in the vertical direction.

[0054] Working principle of the present invention:

[0055] (1) When the wind force is relatively low, in the gathering and unloading conversion mechanism, the wind scoop wind shield 44 is located near the outside of the wind gathering cover 2, and the inner end partition 422 and the outer edge partition 421 are relatively closed, so that a wind gathering channel is formed between the two groups of gathering and unloading conversion mechanisms 4, that is, a 120° windward opening is formed; to ensure that when the wind force is relatively low, the wind enters the central wind gathering mechanism 3, blows the blades to rotate, and the blade tube 33 rotates, and the wind force is transmitted to the generator 5;

[0056] (2) When the wind force becomes stronger, the wind shield plate 44 located on the outside is affected by the wind force and moves inward; driven by the synchronous belt 431, the inner end partition plate 422 is pulled to move outward, and a wind discharge channel is formed between the inner end partition plate 422 and the wind collecting mechanism, so that the excess wind force is discharged; the remaining wind force enters the wind collecting mechanism, thereby ensuring the smooth operation of the wind collecting mechanism; at the same time, the wall of the wind shield rotating drum 32 is subjected to the friction force generated by the extrusion of the outer edges of the three synchronous belts 431, and driven by the synchronous belt 431, the wind shield rotating drum 32 is driven to rotate synchronously;

[0057] (3) When the wind force reaches the maximum working wind force (overspeed to level 17), the wind bucket wind shield plate 44 stops moving when it moves to the maximum inner position, and the wind discharge channel is opened to the maximum; at this time, the synchronous belt 431 stops running, and the wind shield rotating cylinder 32 stops moving. Its arc wind shield plate 322 moves to the air inlet 313 on the support cylinder 31, and the force-bearing area of ​​the fan blade is minimized, thereby protecting the internal structure of the fan blade cylinder 33;

[0058] (4) When the wind force gradually weakens again, the wind force on the wind shield 44 decreases, and the wind shield 44 slowly returns to its original position under the tension of the spring. At low wind speeds, the force on the wind shield 44 decreases and the wind shield 44 does not move.

[0059] The above contents are detailed descriptions of the present invention in combination with the preferred technical solutions. It cannot be determined that the specific implementation of the invention is limited to these. Simple deductions and replacements made without departing from the concept of the present invention should be regarded as the protection scope of the present invention. For example, the partition assembly and linkage assembly protected by the present invention and other forms that can achieve the same function are not limited to a few parts to prevent deformation and imitation. And it also falls within the protection scope when applied to super-large size.

7. The adaptive wind gathering and unloading dual-purpose module capacity-increasing wind power generation system according to claim 1, characterized in that: In the gathering and unloading conversion mechanism, the wind collecting mechanism can be additionally arranged at the interval formed between the two inner end partitions, so that the wind force unloaded from the unloading port can be reused for the second time.

8. The adaptive wind gathering and unloading dual-purpose module capacity-increasing wind power generation system according to claim 1, characterized in that: The wind gathering hood, wind collecting mechanism and gathering and unloading conversion mechanism constitute a wind generating set with multiple ones, which are stacked in the vertical direction.
