Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and more specifically, to an intelligent adjustable wind-concentrating cover. Background Technology

[0002] As one of the core methods of utilizing renewable and clean energy, wind power generation occupies an important position in the transformation of energy structure. As a key supporting component of wind power generation equipment, the wind collector's core function is to gather natural wind and increase the wind speed at the outlet, thereby improving the wind energy capture efficiency of the wind turbine and directly affecting the overall operating efficiency and power generation of the power generation equipment.

[0003] Currently, most wind collectors on the market adopt a fixed, integrated structure design. The size of their wind-gathering inlet and their windward area are fixed, making it impossible to adapt to real-time wind speeds. This type of fixed-structure wind collector has several technical drawbacks in practical applications: In low-wind conditions such as light breezes, the fixed inlet area cannot maximize the collection of dispersed natural wind, resulting in low wind energy harvesting efficiency and even failing to drive the wind turbine blades, making it difficult for the power generation equipment to start and operate in low-wind-speed environments; In high-wind conditions, the fixed, large-sized inlet will subject the wind collector to significant wind loads, which can easily lead to fatigue deformation of the frame and connecting components over time, reducing the equipment's lifespan; In extreme wind conditions such as gales and storms, the excessively large windward area will subject the wind collector to wind loads far exceeding the design threshold, easily causing structural cracking, deformation, or even complete damage. This can also damage subsequent core components such as the generator blades and motor, increasing maintenance costs and downtime.

[0004] Furthermore, existing fixed-structure wind concentrators are mostly designed with a straight cylindrical airflow path, lacking an effective wind speed amplification structure. Even under moderate wind conditions, they cannot achieve efficient wind energy utilization. Moreover, most wind concentrators lack dedicated wind leakage protection structures, and there is no effective load-bearing method in the face of extreme winds, further increasing the risk of equipment damage. In summary, existing fixed-structure wind concentrators cannot meet the usage requirements of different wind conditions such as light winds, strong winds, and gales, and face the technical challenges of "insufficient wind energy utilization at low wind speeds and poor structural safety at high wind speeds." This limits the promotion and application of wind power generation equipment in different wind environments and regions. There is an urgent need to develop a wind concentrator that can adaptively adjust according to wind speed and balance wind energy utilization and structural protection. Summary of the Invention

[0010] In a preferred embodiment, the vent plate is a plate-shaped structure and is symmetrically distributed on both sides of the vent of the frame. One end of the vent plate is hinged to the frame, and the hinged end of the vent plate is connected to the output end of the cylinder.

[0011] In a preferred embodiment, the frame is an overall funnel-shaped cavity structure, the cross-sectional area of ​​the air inlet of the frame is larger than the cross-sectional area of ​​the air outlet, and the cross-sectional area of ​​the air outlet of the frame is larger than the cross-sectional area of ​​the circular air outlet.

[0016] The present invention provides an intelligent adjustable wind-concentrating hood, the beneficial effects of which include: 1. This intelligent adjustable wind-gathering hood fundamentally solves the technical problem that existing wind-gathering hoods cannot adapt to all working conditions from light wind to gale. Its adjustment and protection process achieves full-condition adaptive adaptation: when the outside wind is light or gentle, the roller shutter adjustment plate 6 adjusts the wind-gathering opening area to the maximum to maximize the gathering of natural wind; when the outside wind gradually increases, the roller shutter adjustment plate 6 moves synchronously with the increase in wind force, adjusting the wind-gathering opening area to the windward area that matches the current wind force, ensuring load balance; when the outside wind force reaches its maximum or gale, the roller shutter adjustment plate 6 reduces the wind-gathering opening area to the minimum, and at the same time, the vent plate 9 automatically opens under the control of the cylinder 10 to achieve venting protection, effectively preventing structural damage to the wind-gathering hood due to wind overload.

[0017] 2. Through adaptive adjustment under all working conditions, this intelligent adjustable wind gatherer can make full use of wind energy to the maximum extent. Especially under light or low wind conditions, it can amplify the wind force of natural wind several times, significantly improve the wind energy utilization rate, and truly realize the core function of the intelligent adjustable wind gatherer, ensuring stable use of the equipment and efficient wind energy utilization under all wind conditions.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-6 This invention provides a technical solution: an intelligent adjustable wind-gathering hood, comprising a frame 1, which is the main skeleton of the intelligent adjustable wind-gathering hood, serving as the basic structure of the entire device and fixing various components. A fixing frame 2 is fixedly connected to the outer surface of the frame 1, and the fixing frame 2 is fixed to the corresponding position area of ​​the roller shutter adjustment plate 6, stabilizing the frame 1. A first air guide plate 3 is fixedly connected to the inner side of the frame 1. Both the first air guide plate 3 and the second air guide plate 4 are trapezoidal plate structures. The second air guide plate 4 is fixedly connected to the inner wall of the frame 1. The first air guide plate 3 is symmetrically distributed on both sides of the wind-gathering inlet of the frame 1, and the second air guide plate 4 is symmetrically distributed on both sides of the wind-draining inlet of the frame 1. To achieve the air guiding function, a circular air outlet 5 is fixedly connected to one end of the frame 1, and a roller shutter adjustment plate 6 is movably connected to the inner side of the frame 1. The circular air outlet 5 is a circular tubular structure, and the axis of the circular air outlet 5 coincides with the center line of the air passage of the frame 1. The fixing frame 2 is a rod-shaped structure and at least two are provided. Multiple fixing frames 2 are evenly distributed in the outer area of ​​the frame 1 corresponding to the roller shutter adjustment plate 6. An adjustment plate retraction and storage plate 7 is fixedly connected to the outer surface of the frame 1. A baffle 8 is fixedly connected inside the adjustment plate retraction and storage plate 7. A vent plate 9 is movably connected to the inner side of the frame 1. A cylinder 10 is fixedly connected to the inner wall of the frame 1, and the output end of the cylinder 10 is fixedly connected to the vent plate 9.

[0023] In this embodiment, frame 1 is integrally welded from alloy steel and has a trumpet-shaped cavity structure. Its inner wall is polished to form a smooth curved surface. The cross-sectional area of ​​the air inlet is 2.5㎡, the cross-sectional area of ​​the air outlet is 1.5㎡, and the cross-sectional area of ​​the circular air outlet 5 is 0.8㎡, forming a gradient area airflow layout. The fixing frame 2 is made of four solid stainless steel rods, which are evenly distributed on the outer area of ​​frame 1 corresponding to the roller shutter adjustment plate 6. One end of the rod is welded to frame 1, and the other end can be fixed to the external mounting base through expansion bolts to improve the structural stability of frame 1. The air guide plate 1 3 and the air guide plate 2 4 are both made of stainless steel plates and have a trapezoidal structure with a polished surface. Air guide plate 1 3 is symmetrically welded on both sides of the air inlet of frame 1, and air guide plate 2 4 is symmetrically welded on both sides of the air outlet of frame 1. Both form a 30° air guiding angle with the inner wall of frame 1 to ensure efficient convergence and release of air force.

[0024] The roller shutter adjustment plate 6 has a roller shutter door structure. The retractable end of the roller shutter adjustment plate 6 extends into the interior of the adjustment plate retraction and storage plate 7. The adjustment plate retraction and storage plate 7 has a hollow cavity structure. The baffle 8 has an arc-shaped plate structure and is adapted to the inner wall of the adjustment plate retraction and storage plate 7. Its operation is adapted to the external wind conditions: when the external wind is light or gentle, the roller shutter adjustment plate 6 is adjusted to the maximum size of the wind gathering port to maximize the gathering of natural wind and improve wind energy utilization. When the external wind gradually strengthens, the roller shutter adjustment plate 6 moves synchronously with the increase of wind force, gradually reducing the windward area of ​​the wind gathering port to keep the wind load on the wind gathering hood within a reasonable range. When the external wind force reaches the maximum or the wind force reaches the preset threshold, the roller shutter adjustment plate 6 is adjusted to reduce the wind gathering port area to the minimum size to further reduce the wind load on the wind gathering hood and prevent the wind gathering hood from being damaged due to excessive load, thus achieving a dynamic balance between wind energy utilization and structural protection. The retractable storage plate 7 is a dedicated storage area for the roller shutter retractable plate 6. When the wind force is strong and the roller shutter retracts, the roller shutter retracts and is stored inside the retractable storage plate 7. The baffle 8 is fixed inside the retractable storage plate 7, forming a protective cover for the retracted area and also serving as a wind guide. The vent plate 9 is located on the left and right sides of the vent. When the outside wind force reaches its maximum or during gale conditions, the vent plate 9 is opened by the cylinder 10, releasing some of the wind force through the vent channel. This further reduces the wind load on the wind collector, preventing damage to the wind collector due to overload, extending its service life, and improving its reliability under extreme wind conditions.

[0025] The air vent 9 is a plate-shaped structure symmetrically distributed on both sides of the air vent of the frame 1. One end of the air vent 9 is hinged to the frame 1, and the hinged end of the air vent 9 is connected to the output end of the cylinder 10. The air vent adjustment part achieves adaptive adjustment of the air gathering port area and integrated control of air vent protection under strong wind conditions through the coordinated action of the roller shutter adjustment plate 6 and the air vent 9. Specifically, the roller shutter adjustment plate 6 automatically adjusts the windward area of ​​the air gathering port according to the external wind force, and the air vent 9 responds synchronously to the wind force threshold signal. When the wind force reaches the preset extreme value, it is controlled by the cylinder 10 to open. The two work together to ensure the wind energy gathering effect under light wind conditions, the load balance under strong wind conditions, and safe air venting under strong wind conditions. It comprehensively takes into account the usage needs of different wind force conditions such as light wind, strong wind, and strong wind, and improves the adaptability and working condition range of the equipment.

[0026] The frame 1 has an overall trumpet-shaped cavity structure. The cross-sectional area of ​​the air inlet of the frame 1 is larger than that of the air outlet, and the cross-sectional area of ​​the air outlet of the frame 1 is larger than that of the circular air outlet 5. The areas of the air inlet, air outlet, and circular air outlet satisfy the following condition: air inlet area > air outlet area > circular air outlet area. Through this gradient area design, a wind path layout of "large air inlet area and small air outlet area" is achieved, effectively amplifying the wind speed passing through the equipment by utilizing fluid dynamics principles. Especially in light or low wind conditions, the roller shutter adjustment plate 6 can be adjusted to the maximum air inlet state to maximize the gathering of natural wind. Combined with the speed-increasing effect of the trumpet-shaped structure, the wind force of natural wind can be amplified several times, significantly improving the wind energy utilization rate. This effectively solves the technical defect of insufficient wind energy utilization in light wind conditions of existing fixed structure wind hoods, further enhancing the applicability of the equipment in low wind conditions.

[0027] A sliding connection structure is provided between the two sides of the roller shutter adjustment plate 6 and the inner wall of the frame 1. The opening end of the adjustment plate retraction storage plate 7 is connected to the inner wall of the frame 1. The arc-shaped surface of the baffle 8 faces the inside of the adjustment plate retraction storage plate 7.

[0028] At least two cylinders 10 are provided, symmetrically distributed on the inner wall of the frame 1. The cylinder body end of the cylinder 10 is fixedly connected to the inner wall of the frame 1. The opening angle of the vent plate 9 is 0-90°. The intelligent adjustable wind-gathering hood of the present invention can form a closed-loop control system with the wind power detection module, the electronic control module, and the pneumatic pump station. The wind power detection module adopts a wind speed sensor, which is installed on the outside of the wind-gathering port of the frame 1. It can detect the wind speed and wind force in real time and transmit the detection signal to the electronic control module. The electronic control module adopts a PLC controller with a built-in preset wind force threshold program. It can automatically control the operation of the retraction drive motor of the roller shutter adjustment plate 6 and the pneumatic pump station according to the signal of the wind speed sensor. The pneumatic pump station provides a high-pressure air source for the cylinder 10 to realize the extension and retraction action of the cylinder 10.

[0029] Frame 1, fixing frame 2, air guide plate 1, and air guide plate 2 are all made of metal. The roller shutter adjustment plate 6 is a metal roller shutter structure, and the air vent plate 9 is a metal plate structure. The inner wall of the trumpet-shaped cavity structure of frame 1 is a smooth curved surface. The center lines of the air gathering port, air vent, and circular air outlet 5 of frame 1 coincide. The adjustment plate retraction storage plate 7 is a stainless steel hollow cavity structure, welded to the outside of frame 1, with its opening end connected to the inner wall of frame 1. The internal space can completely accommodate the retracted roller shutter adjustment plate 6. The baffle 8 is an arc-shaped stainless steel plate, welded to the adjustment plate retraction storage plate 7. Inside, its arc-shaped surface faces the inside of the adjustment plate retraction storage plate 7, forming a smooth air guide surface with the inner wall of the adjustment plate retraction storage plate 7; the vent plate 9 is an aluminum alloy plate structure, symmetrically arranged on both sides of the vent of the frame 1, one end of which is hinged to the frame 1 through a wear-resistant rotating shaft, and the rotating shaft is coated with high-temperature grease to ensure rotation flexibility; the cylinder 10 adopts two small pneumatic cylinders, which are symmetrically fixed on the inner wall of the frame 1, the cylinder body end is welded to the frame 1, and the output end is fixedly connected to the hinge end of the vent plate 9, which can drive the vent plate 9 to achieve an opening angle adjustment of 0-90°.

[0030] In this embodiment, the preset wind speed thresholds are: light wind (wind speed ≤ 3m / s), strong wind (3m / s < wind speed < 8m / s), and gale (wind speed ≥ 8m / s). The electronic control module controls the equipment to achieve different working states according to different wind speed ranges. The specific working process is as follows: Light wind conditions When the wind speed sensor detects an outside wind speed ≤3m / s, it transmits the signal to the PLC controller. The PLC controller controls the retraction drive motor of the roller shutter adjustment plate 6 to run in the forward direction, causing the roller shutter adjustment plate 6 to fully unfold along the sliding groove on the inner wall of the frame 1, so that the windward area of ​​the air gathering port reaches a maximum of 2.5㎡. At this time, there is no roller shutter adjustment plate 6 inside the retraction storage plate 7, and the baffle 8 forms a protective and air guiding structure. At the same time, the PLC controller controls the pneumatic pump station to be in a depressurized state, and the output end of the cylinder 10 fully retracts, causing the air vent plate 9 to fully close and fit tightly against the inner wall of the frame 1, ensuring the airtightness of the air duct of the air gathering hood.

[0031] Guided by the wind deflector 3, the natural wind converges towards the central wind path of the frame 1. Since the frame 1 is a funnel-shaped cavity structure, and the wind inlet, wind outlet, and circular air outlet 5 are designed with gradient areas, the natural wind is accelerated inside the wind path of the frame 1 by utilizing the Venturi effect. The wind speed can be amplified to 2-3 times the original wind speed. The accelerated natural wind is then delivered to the blade end of the wind turbine through the circular air outlet 5, effectively driving the blade to rotate. This achieves efficient utilization of wind energy in low wind speed environments and solves the technical defect that the existing fixed structure wind deflector cannot start the generator under light wind conditions.

[0032] High wind conditions When the wind speed sensor detects that the outside wind speed is between 3m / s and 8m / s, it transmits the signal to the PLC controller. The PLC controller controls the retraction drive motor of the roller shutter adjustment plate 6 to run in the opposite direction at the corresponding angle according to the real-time wind speed. This causes the roller shutter adjustment plate 6 to retract along the slide rail into the retraction storage plate 7, gradually reducing the windward area of ​​the air gathering port. The retraction area is proportional to the wind speed. The higher the wind speed, the greater the retraction of the roller shutter adjustment plate 6 and the smaller the windward area of ​​the air gathering port, so that the wind load borne by the frame 1 is always kept within the reasonable design range of ≤500N / ㎡.

[0033] For example, when the wind speed is 5 m / s, the PLC controller controls the roller shutter adjustment plate 6 to retract by 1 / 3, reducing the windward area of ​​the air-gathering inlet to 1.7 m²; when the wind speed is 7 m / s, it controls the roller shutter adjustment plate 6 to retract by 2 / 3, reducing the windward area of ​​the air-gathering inlet to 0.8 m². During this process, the cylinder 10 remains in the retracted state, the vent plate 9 remains closed, the guide plate 3 continues to guide the wind force to converge, and the trumpet-shaped structure of the frame 1 still achieves wind force acceleration. While ensuring wind energy collection efficiency, it avoids fatigue deformation of components such as the frame 1 and the fixed frame 2 due to excessive wind load, achieving a dynamic balance between wind energy utilization and structural load, and extending the service life of the equipment.

[0034] The retracted roller shutter adjustment plate 6 is stored inside the adjustment plate retraction storage plate 7. The baffle 8 protects it from dust, sand and other debris entering the slide and affecting the adjustment action. At the same time, the arc-shaped structure of the baffle 8 forms a smooth air guide surface, avoiding the generation of vortices inside the adjustment plate retraction storage plate 7 and reducing wind resistance loss.

[0035] High wind conditions When the wind speed sensor detects an external wind speed ≥8m / s, it transmits the signal to the PLC controller. The PLC controller immediately controls the retraction drive motor of the roller shutter adjustment plate 6 to run in reverse at full load, causing the roller shutter adjustment plate 6 to retract completely into the interior of the adjustment plate retraction storage plate 7, reducing the windward area of ​​the air inlet to a minimum of 0.5㎡, actively reducing the windward load on the frame 1, and reducing the wind load to less than 1 / 5 of the design threshold. At the same time, the PLC controller controls the pneumatic pump station to start, outputting high-pressure air to the cylinder 10, pushing the output end of the cylinder 10 to fully extend, causing the vent plate 9 to rotate around the hinge axis to a 90° open state, so that the vent of the frame 1 is fully opened.

[0036] After the natural wind is gathered by the wind guide plate 3, part of the wind force is transported to the generator through the circular air outlet 5 along the central wind path of the frame 1, while the other part of the wind force is quickly released from the air vent under the guidance of the wind guide plate 4, thus unloading the wind force. Through the dual protection of "actively shrinking the wind gathering port + passively opening the air vent", the actual wind load borne by the frame 1 is reduced to ≤100N / ㎡, which is far below the design threshold. This effectively avoids structural cracking and deformation of the frame 1, and also prevents excessive wind force from impacting the core components such as the generator blades and motor, ensuring the operational stability of the entire wind power generation equipment under extreme wind conditions.

[0037] When the outside wind speed drops below 8 m / s, the wind speed sensor transmits a signal to the PLC controller. The PLC controller first controls the pneumatic pump station to depressurize, the output end of the cylinder 10 contracts, driving the air vent plate 9 to close. Then, according to the actual wind speed, it controls the roller shutter adjustment plate 6 to gradually unfold, restoring the working state to the corresponding wind speed. The whole process does not require manual intervention, realizing automated working condition switching.

[0038] Specifically, the working process or principle of this intelligent adjustable wind concentrator is as follows: During use and installation, the frame 1 is fixedly connected to the external installation foundation through the fixing bracket 2, and the flange of the circular air outlet 5 is fixedly connected to the air inlet of the wind turbine. The wind speed sensor is installed on the outside of the wind concentrator of the frame 1. The circuit and air circuit connections of the wind speed sensor, PLC controller, retraction drive motor, pneumatic pump station, and cylinder 10 are completed. After the wind force threshold is preset, the equipment enters the automatic operation state. Under light wind conditions, the roller shutter adjustment plate 6 is fully extended and the air vent plate 9 is closed, and the natural wind is gathered by the air guide plate 3. After the horn-shaped structure of frame 1 increases speed, the air is delivered to the generator through the circular air outlet 5, realizing the utilization of wind energy at low wind speeds. Under high wind conditions, the roller shutter adjustment plate 6 retracts in real time according to the wind speed, reducing the windward area of ​​the air gathering port and keeping the wind load reasonable. The vent plate 9 remains closed, balancing wind energy utilization and structural protection. Under gale conditions, the roller shutter adjustment plate 6 retracts completely and the vent plate 9 opens completely, achieving dual unloading through active retraction and passive venting to avoid damage to the equipment structure. When the wind speed recovers, the equipment automatically switches to the corresponding working state. The entire process is automated and intelligently controlled, requiring no manual intervention.
