Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and more specifically, it relates to a wind-gathering shroud wind diversion device. Background Technology

[0002] A wind turbine is a clean energy device that converts wind energy into electrical energy. It mainly consists of a wind turbine (including blades), a generator, a tower, and a control system. The wind drives the wind turbine blades to rotate, and the rotational kinetic energy is transmitted to the generator through transmission components such as the main shaft and gearbox. The generator then converts the mechanical energy into electrical energy, which is processed by equipment such as converters before being connected to the power grid or stored for use. It is widely used in onshore and offshore wind farms, and can generate electricity using renewable wind energy, reducing dependence on fossil fuels and reducing carbon emissions. It is an important green energy device in the global energy transition.

[0003] In low-wind-speed environments, the airflow struggles to overcome the inherent resistance of the wind turbine blades, affecting the normal power generation of the wind turbine. In such cases, a wind-collecting shroud is typically installed on one side of the wind turbine to collect and guide the airflow, thereby enhancing the propulsion force on the wind turbine blades. This allows the wind turbine to generate electricity stably even in low-wind-speed environments. However, natural winds are not regular, and sudden changes in airflow velocity can impact the wind turbine. For example, when wind speeds increase, the increased impact load or sudden stress changes can exacerbate component wear and fatigue, and even lead to equipment damage risks such as blade breakage and gearbox jamming. Furthermore, frequent changes in wind speed can easily create turbulent flow and eddies inside or at the outlet of the wind-collecting shroud, disrupting the originally stable airflow pattern and causing uneven stress on the wind turbine. This not only reduces wind collection efficiency (and may even cause "backlash" to offset some of the wind force), but also causes significant fluctuations in power generation, affecting the stability of power output and increasing the difficulty of grid adaptation.

[0004] Therefore, in order to solve the above problems, we propose a wind hood wind diversion device. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides the following technical solution: A wind-gathering hood wind-diverting device includes a wind-gathering hood, and a wind-gathering hood wind-diverting device is provided on one side of the wind-gathering hood: The wind-gathering hood wind-power diversion device adopts a modular design and forms a synergistic wind power generation matrix system with the wind-gathering hood array. Each wind-gathering hood wind-power diversion device is precisely positioned at the junction of the air inlet side of two wind-gathering hoods, forming a continuous air duct guiding interface and constructing a complete matrix flow field.

[0006] Furthermore, the wind-gathering hood wind-diverting device includes a bottom frame and a top frame, which are connected by a four-sided frame. Fixed support rods are symmetrically fixedly installed on the inner side of the bottom frame, and long push rod support rods are fixedly installed between the fixed support rods. A diversion component for guiding airflow is provided on the outer wall of the bottom frame, and an adjustment component for adjusting the diversion effect is provided on the outer wall of the long push rod support rod. Wind-gathering components for improving airflow are provided on both outer walls of the top frame. A wind speed sensor is installed inside the wind-gathering hood wind-diverting device.

[0007] Furthermore, the wind-gathering assembly includes baffle rotation shafts disposed on the outer walls of both sides of the top frame. A baffle is fixedly installed on one side of each baffle rotation shaft. The shape of the baffle is the same as the rectangle formed by the bottom frame, the surrounding frames, and the top frame.

[0008] Furthermore, the shape of each baffle is L-shaped, and one end of each baffle abuts against a short push rod, which is fixedly installed on the outer wall of the top frame.

[0009] Furthermore, the diversion assembly includes a diversion plate rotating shaft bearing disposed on the outer wall of the bottom frame, a diversion plate rotating shaft is fixedly installed between the diversion plate rotating shaft bearings, and a diversion plate is fixedly installed on one side of the diversion plate rotating shaft.

[0010] Furthermore, the adjustment assembly includes a lower bearing for the long push rod disposed on the outer wall of the long push rod support rod.

[0015] 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 scope of protection of the present utility model.

[0016] Example: The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a wind-gathering hood wind diversion device, such as... Figure 1-5As shown, the device includes a wind-gathering hood 17, with a wind-gathering hood wind-diverting device 16 on one side. The wind-gathering hood wind-diverting device 16 includes a bottom frame 13 and a top frame 15, which are connected by a perimeter frame 14. Fixed support rods 8 are symmetrically fixedly installed on the inner side of the bottom frame 13 for stability. Long push rod support rods 9 are fixedly installed between the fixed support rods 8. A diversion component for guiding airflow is provided on the outer wall of the bottom frame 13, and an adjustment component for adjusting the diversion effect is provided on the outer wall of the long push rod support rod 9. Wind-gathering components for improving airflow are provided on both outer walls of the top frame 15. The flow diversion assembly includes a flow diversion plate rotating shaft bearing 3 disposed on the outer wall of the bottom frame 13. A flow diversion plate rotating shaft 2 is fixedly installed between each of the flow diversion plate rotating shaft bearings 3. A flow diversion plate 1 is fixedly installed on one side of each flow diversion plate rotating shaft 2. This design can streamline the turbulent airflow formed at the edge of the wind-gathering shroud 17, guiding the airflow along the inner wall of the flow diversion plate 1, reducing turbulence caused by airflow collisions and swirling. Since turbulence significantly increases the frictional resistance and pressure difference resistance between the airflow and the wind-gathering shroud 17, the flow diversion plate 1 in this embodiment can suppress turbulence, reducing the ineffective loss of airflow energy, thereby reducing the overall drag coefficient. Furthermore, the adjustment assembly includes a long push rod lower bearing 7 disposed on the outer wall of the long push rod support rod 9. Two long push rod lower bearings 7 are symmetrically installed. One side of each bearing 7 is rotatably mounted with a long push rod rotating fixing block 6. One end of each long push rod rotating fixing block 6 is fixedly mounted with a long push rod 5. The long push rod 5 is driven by a servo motor (not shown in the figure, and the servo motor is a mature existing technology, so its internal structure and working principle will not be described in detail). The other end of each long push rod 5 is rotatably mounted with a long push rod bearing 4. The long push rod bearing 4 is fixedly mounted on one side of the diverter plate 1. The wind speed sensor set inside the wind diversion device 16 can monitor the airflow intensity in the environment in real time, and send a signal to control the servo motor to drive the long push rod 5 when the airflow in the environment changes. This causes the long push rod 5 to extend and retract to control the rotation of the diverter plate 1, thereby realizing precise angle adjustment of the diverter plate 1, diverting the wind, and improving the wind energy utilization rate.

[0018] It should be further explained that the wind-diverting device 16 of the wind-concentrating hood adopts a modular design and forms a synergistic wind power generation matrix system with the array of wind-concentrating hoods 17. Each wind-diverting device 16 of the wind-concentrating hood is precisely positioned at the junction of the air inlet side of two wind-concentrating hoods 17, forming a continuous air duct guiding interface and constructing a complete matrix flow field. Through the cooperation of the diversion component and the adjustment component, the wind-diverting device 16 of the wind-concentrating hood is innovatively arranged in the transition area of ​​adjacent wind-concentrating hoods 17, forming a cascaded wind energy utilization structure of "wind concentration-diversion-reconcentration". By setting each wind-diverting device 16 of the wind-concentrating hood to be precisely positioned at the junction of the air inlet side of two wind-concentrating hoods 17, a continuous air duct guiding interface is formed, and a complete matrix flow field is constructed. This wind-diverting device 16 of the wind-concentrating hood, through flow field reconstruction technology, not only solves the problem of wake interference in traditional wind fields, but also realizes energy complementarity between wind-concentrating units. It is an innovative design to improve wind energy utilization. In this embodiment: through the cooperation of the diversion component and the adjustment component, when the airflow in the environment changes (such as a sudden increase or frequent fluctuation in flow velocity), the wind speed sensor can send a signal to adjust the angle of the diversion plate 1 in real time according to the actual wind conditions. When the airflow velocity increases, precise diversion avoids excessive airflow from causing impact loads on components such as the wind turbine and gearbox, reducing wear caused by sudden stress changes. At the same time, it optimizes the airflow pattern and suppresses the generation of turbulence and eddies in the wind shroud 17, which not only improves the wind energy utilization rate at low wind speeds, but also ensures the stability of the airflow driving the wind turbine at high wind speeds or variable wind speeds, thereby extending the service life of the wind turbine and improving the stability of power output to meet grid demand. Compared with the prior art, the existing wind shroud 17 devices are all fixed and non-adjustable, so they cannot well take into account the changes from light wind to strong wind and even gales. The issue of wind is problematic. If a gentle breeze is achieved, the wind turbine will be damaged in strong winds, presenting a trade-off. However, the wind-gathering shield wind-distribution device 16 in this embodiment fundamentally solves this problem. In light breezes, the distributor plate 1 is fully closed, increasing wind power utilization and diverting the wind force into the two wind-gathering shields 17. As the wind intensifies, the distributor plate 1 adjusts to the corresponding windward angle. When the wind reaches its maximum or becomes a strong wind, the wind-gathering shield wind-distribution device 16 unfolds the distributor plate 1 to align with the wind direction, dispersing the wind force and preventing damage. This maximizes the utilization of wind energy, increasing the natural wind force several times (especially in light winds), better fulfilling the function of the wind-gathering shield 17, and thus improving the power generation efficiency of the wind turbine.

[0019] like Figure 1-4As shown, the wind-gathering assembly includes baffle rotating shafts 11 disposed on the outer walls of both sides of the top frame 15. Baffles 10 are fixedly installed on one side of each baffle rotating shaft 11, so that the baffles 10 can assist in guiding the airflow and prevent the airflow from entering the interior of the wind-gathering hood wind-power diverting device 16 from both sides, thereby causing collision and interference with the radially guided airflow inside the wind-gathering hood wind-power diverting device 16, forming turbulence, affecting the airflow velocity and stability, and thus affecting the power generation efficiency of the wind turbine. The shape of the baffles 10 is the same as the rectangle formed by the bottom frame 13, the surrounding frames 14 and the top frame 15, wherein the area of ​​the rectangle formed by the top frame 15 is larger than the area of ​​the rectangle formed by the bottom frame 13. This design allows the baffles 10 and the wind-gathering hood wind-power diverting device 16 to form a funnel shape with a wide inlet and a narrow outlet, further improving the gathering effect of the wind-gathering hood wind-power diverting device 16 on the surrounding air, reducing airflow resistance and improving air intake efficiency. Furthermore, all baffles 10 are L-shaped, with one end of each baffle 10 abutting against a short push rod 12, creating a flexible connection between the short push rod 12 and the baffle 10. The short push rods 12 are fixedly installed on the outer wall of the top frame 15. This design ensures that when the wind speed is low, the short push rods 12 tightly abut against the L-shaped end of the baffle 10, leveraging the principle to firmly attach the baffle 10 to one side of the wind-gathering hood wind diversion device 16, thus forming a funnel-shaped wind-gathering channel. This further enhances the power generation efficiency of the wind turbine, enabling stable power generation even in low-wind-speed environments. Conversely, when the wind speed is high, the wind speed transmission... The sensor detects that a preset gale threshold has been reached and sends a signal to control the extension and retraction of the short push rod 12, causing the short push rod 12 to stop limiting the baffle 10. At this time, the baffle 10 can swing adaptively with the wind force, which can reduce wind resistance, reduce the wear of the baffle 10, and greatly extend the service life of the baffle 10 and its connecting parts. In addition, when the short push rod 12 stops limiting the baffle 10, the short push rod 12 will send a signal to control the diverter plate 1 and the baffle 10 to expand synchronously, quickly forming a venting channel. This venting channel can control the peak wind pressure on the wind-gathering hood 17 within a safe range and avoid plastic deformation of the structural components.

[0020] In this embodiment: by setting up a wind-gathering component, it is possible to prevent airflow from entering from both sides of the wind-gathering hood wind-diverting device 16 and affecting the airflow inside the wind-gathering hood wind-diverting device 16. At the same time, it can also form a funnel-shaped wind-gathering channel with the wind-gathering hood wind-diverting device 16, thereby enhancing the wind-gathering hood wind-diverting device 16's effect on gathering and guiding airflow, further enhancing the power generation efficiency of the wind turbine. Furthermore, by setting up a short push rod 12, on the one hand, the stability of the funnel-shaped wind-gathering channel in low wind speed environments can be enhanced. On the other hand, in strong wind environments, the funnel-shaped wind-gathering channel can be disengaged, avoiding additional wear and tear on the wind-gathering component and extending its service life.
