Description

Technical Field

[0001] The utility model relates to the field of wind power generation, and specifically discloses a horizontal air collecting and guiding wind power generating set. Background Art

[0002] The fan blades of traditional small wind power generating sets are mostly of an external structure, and their impacts on the environment include multiple aspects, mainly involving ecological damage, climate impact, and noise pollution.

[0003] Ecological damage: The construction and operation of wind turbines may cause land damage, soil erosion and soil erosion, thereby destroying the balance of the ecosystem. In addition, the rotating blades will disrupt the habitats and food sources of birds, resulting in bird deaths.

[0004] Climate impact: The construction and operation of wind turbines may affect the climate, such as changing the wind direction and wind speed. As a kind of energy that utilizes the wind energy in the atmosphere, the power generation process of wind power will consume a part of the wind energy in the atmosphere, which may have an impact on the local microclimate.

[0004]

[0005] Noise pollution: The operation of wind turbines will generate noise, causing interference and pollution to the surrounding environment and the lives of residents.

[0006] On the other hand, the orientation adjustment method and the wind receiving method of small wind power generating sets have a crucial impact on the power generation efficiency. At present, some manufacturers have adopted an intelligent orientation system to optimize the orientation adjustment method. By a manually preset control system, the wind direction change is predicted and parameters such as the rotational speed, torque and vibration of the fan are comprehensively considered, and the steering angle of the wind power generating set and the angle of the wind turbine blades are automatically adjusted to maximize the power generation efficiency. However, there are also problems such as lag in wind direction adjustment and operation failures and safety hazards caused by frequent wind direction changes, thus reducing the service life of the equipment.

[0005]

[0007] In view of the above problems of small wind power generating sets in terms of environment and wind receiving and orientation adjustment, there are problems in the application process of small wind power generating sets such as unstable adjustment of the wind receiving direction and steering angle, low power generation efficiency, unstable power generation, and ineffective guarantee of safety and service life, which restricts the popularization and application of small wind power generating sets. At the same time, the impact factors of the fan blades of the wind power generating set on the environment also become a major obstacle to the popularization and application of small wind power generating sets.

[0008] As a R & D unit of products in this field, it is urgent to improve the overall structure of small wind power generation equipment to overcome various drawbacks in the prior art.

A fixed grooved wheel 551 is arranged inside the spigot fixing structure, and the fixed grooved wheel 551 is radially fixed to the upper groove structure 51 in the circumferential direction.

[0044] The support platform 6 is located at the bottom of the radial air collecting and rotating part 5.

[0045] Example 2: The rotation process of the air collecting and guiding frame As Figures 1 to 3 shown, the air collecting and guiding frame 1 is jointly composed of a top windward plate 11, a bottom windward plate 12, a left deflector 13, and a right deflector 14 to form a conical bell-shaped deflector hood. At the same time, in combination with the wind direction adjusting plate 2, the air collecting and guiding frame 1 is always kept on the windward side of the wind direction; the upper groove structure 51 in the radial air collecting and rotating part 5 is fixedly connected to the bottom windward plate 12 in the air collecting and guiding frame 1. During the rotation process, the support bracket 53 and the rotating sphere 54 in the radial air collecting and rotating part 5 rotate synchronously in the circumferential direction under the action of the circumferential grooves on the upper groove structure 51 and the lower groove structure 52.

[0046] Furthermore, the upper guiding structure 43 and the lower guiding structure 44 in the power generation module 4 are arranged in a cylindrical or shaft-like structure, and the two are respectively fixed to the top windward plate 11 and the bottom windward plate 12 by bolts or welding to form an integral structure.

[0049] Furthermore, the partition inside the horizontal wind turbine rotating body 31 is fixed to the rotor rotating shaft 45 on the generator set 41, and when the horizontal wind turbine rotating structure 3 rotates, it drives the generator set to perform synchronous rotational motion.

[0050] Example 4: The radial rotation and axial fixation process of the rabbet fixing structure As Figure 3 、 4 、7 shown, the rabbet fixing structure 55 includes a fixed grooved pulley 551, a rabbet fixing plate 552 and a rotating connecting shaft 553.
