Description

Technical Field

[0001] This invention relates to the technical field of heat dissipation, and more particularly to a dustproof heat dissipation device. Background Technology

[0002] Currently, SVG (Variable Energy Storage) housings typically dissipate heat by expelling hot air outdoors using external axial fans. However, the traditional aluminum alloy louvers used in SVG housings are ineffective at preventing dust from entering. In inclement weather, direct exchange of indoor and outdoor air allows dust to seep into the SVG housing along with the air. This leads to a buildup of dust on the surface of the SVG power units due to electrostatic attraction, affecting heat dissipation efficiency, ultimately causing frequent SVG equipment failures, increasing maintenance costs, and potentially impacting the wind farm's power generation efficiency.

[0031] Example 1

[0032] Reference Figures 1-7This is the first embodiment of the present invention, which provides a dustproof and heat dissipation device. The device includes a louver 100, including a frame 101. A rotating shaft is rotatably connected to the frame 101. Fixed blades 102 are fixed on the rotating shaft rotatably connected to the frame 101. The other end of the fixed blades 102 is also fixedly connected to a rotating shaft. The fixed blades 102 and movable blades 103 are connected by the rotating shaft. Each movable blade 103 is connected by a rope fixed to the side. A dustproof component 200 is located on one side of the louver 100. The dustproof component 200 includes a fixed bracket 201 fixed to the frame 101. A fixed box 201a is fixedly connected to the fixed bracket 201. The fixed bracket 201 provides fixed support for the reversing component 202, the adjusting component 203, and the wind vane 204. The reversing component 202 and the adjusting component 203 are installed inside the wind vane 204. The reversing component 202 is connected to the adjusting component 203 through the wind vane 204.

[0033] The louver 100 features a unique structure with a double-layer blade system. The fixed blades 102 are made of a heavier material, ensuring the overall structural strength and stability, while the movable blades 103 are made of lightweight and high-strength carbon fiber reinforced plastic. This material is not only lightweight but also maintains good flexibility and durability even in strong winds. The biomimetic airfoil design of the movable blades 103 optimizes aerodynamic performance, reduces wind resistance, and makes the blades rotate more smoothly. The blade edges can be designed with a micro-serrated structure to further enhance dust protection, effectively mitigating wind and sand impact and protecting the internal structure from corrosion.

[0034] The fixed blade 102 is fixedly installed via a pivot on the frame 101 and is designed to rotate non-automatically, requiring manual adjustment only when needed. The movable blade 103 rotates freely around the pivot on the fixed blade 102, automatically adjusting its angle according to wind changes without manual intervention. The movable blades 103 are interconnected by ropes, ensuring that the movement of a single blade synchronously drives the other blades, achieving coordinated opening and closing of the entire system.

[0035] The device incorporates a fixed box 201a, which provides a stable support for the adjustment component 203. When the wind force increases, the movable blade 103 can respond quickly, automatically closing or tilting to the minimum opening state, effectively blocking the intrusion of wind and sand.

[0036] Crucially, the wind vane 204 and its internal reversing assembly 202 are ingeniously designed. Regardless of the direction of rotation, the reversing assembly 202 ensures that the regulating assembly 203 is driven by only one direction. This allows for precise control of the blade opening and closing regardless of wind direction changes, achieving intelligent response to wind speed and direction. This series of purely mechanical designs not only improves dustproof and heat dissipation efficiency but also ensures long-term stable operation and ease of maintenance, making it ideal for use in wind farm SVG rooms or other similar environments in wind-prone areas.

[0037] Specifically, the adjustment component 203 includes several sets of adjustment slots 203a inside the wind vane 204. Each set of adjustment slots 203a has several slots. Each adjustment slot 203a is T-shaped. A first spring 203b is fixedly connected inside each adjustment slot 203a. The elastic force of the first spring 203b in different sets of adjustment slots 203a is different. A T-shaped brake block 203c is fixedly connected to one end of the first spring 203b.

[0038] The adjustment system incorporates a series of ingenious mechanical structures designed to automatically adapt to different wind speed conditions and achieve dynamic dust prevention. Specifically, the wind vane 204 cleverly integrates three sets of adjustment slots 203a, each set containing three slots 203a. This design allows for flexible adjustment of the number of slots 203a according to actual environmental needs, thus adapting to a wider range of wind speeds. Each adjustment slot 203a is equipped with a first spring 203b with a preset elasticity, which holds a T-shaped brake block 203c in place. These springs have different elasticity settings depending on their respective set of adjustment slots 203a, ensuring precise control of wind speed response.

[0039] During operation, as the wind vane 204 rotates with the wind direction, the resulting centrifugal force causes the T-shaped brake block 203c to slide along the adjustment groove 203a. Due to the differentiated spring force design within each adjustment groove 203a, only the T-shaped brake block 203c at the corresponding wind speed level can overcome the spring resistance and slide out of the adjustment groove 203a at the appropriate time under different wind speeds. This mechanism achieves intelligent wind speed sensing and adjustment by precisely adjusting the spring force coefficient of the first spring 203b, ensuring that when the wind speed increases to a preset value, the T-shaped brake blocks 203c slide out sequentially, driving the subsequent gear 203d, causing the louver 100 blades to close or tilt in a timely manner, effectively resisting wind and sand intrusion. The entire process requires no external power, relying entirely on natural wind force and mechanical linkage, demonstrating a highly efficient and adaptive dustproof and heat dissipation solution.

[0040] Furthermore, gears 203d are fitted onto the positions corresponding to the wind vane 204 rod and each set of adjustment slots 203a. Gears 203d have gear rings on both the inside and outside. The outer ring of gear 203d meshes with racks 203e. The number of racks 203e is the same as the number of gears 203d. A T-slot is opened on one side of gear 203d. One end of the T-block of the gear 203d support rod slides in the T-slot of gear 203d. One end of the gear 203d support rod is fixedly connected to the fixed box 201a. A lever 203g is fixedly connected to each rack 203e. The lever 203g rotates around the hinge rod 203h fixed on one side of the fixed box 201a. The hinge rod 203h consists of a straight rod and a hinge ball hinged to the straight rod. The T-block hinged to one end of the lever 203g slides in the T-slot on one side of the movable blade 103.

[0041] The wind vane 204 rod and each corresponding adjustment slot 203a are equipped with gears 203d. These gears 203d not only have internal gear rings but also external rack and pinion 203e meshing structures, ensuring efficient and versatile transmission. The unique feature of the gears 203d is their T-slot design on one side, with a T-block embedded in the gear 203d support rod. This structure allows the gears 203d to slide smoothly along the T-slot under the guidance of the support rod, while the support rod is fixed to the fixed box 201a, ensuring the stability of the entire system.

[0042] Each gear 203d has a rack 203e on its outer periphery connected to an independent lever 203g. These levers 203g rotate around a hinge rod 203h on the side of the fixed box 201a. The hinge rod 203h is constructed with a straight rod and a hinge ball, increasing the flexibility of rotation. Notably, one end of the lever 203g is also equipped with a T-block, which slides in a T-slot next to the movable blade 103. This means that the movement of the lever 203g can directly act on the movable blade 103, achieving opening and closing adjustment.

[0043] The ingenuity of this design lies in the fact that when changes in wind speed cause the T-shaped brake block 203c to slide out of the adjustment groove 203a and drive the gear 203d to rotate, gears 203d at different speeds will each drive the rack 203e connected to them. The rack 203e transmits the motion to the movable blade 103 through the lever 203g system, achieving different degrees of closure. Since different combinations of gears 203d and rack 203e can produce different rotation amplitudes, the degree of closure of the movable blade 103 can be precisely controlled by adjusting the length of the rack 203e, ensuring that the movable blade 103 can automatically adjust its opening and closing as needed under different wind speeds to achieve the best dustproof effect. The sliding design of the lever 203g in the T-groove provides additional adjustment leeway without affecting its rotation function, making the opening and closing adjustment of the movable blade 103 more flexible and precise. It can adapt to various opening and closing needs without changing the length of the lever 203g itself, demonstrating high adaptability and practicality.

[0044] In this device, the gear 203d driven by the fastest wind speed is set to the position closest to the louver 100. With the change of torque of the lever 203g, the movable blade 103 can be quickly closed under high wind speed. This can be achieved by setting the elasticity of the first spring 203b to the minimum.

[0045] Furthermore, a triangular notch is provided on one side of the T-shaped brake block 203c, and a limiting block 203i is fixedly connected to one side of the adjusting groove 203a. The setting direction of the limiting block 203i is located on one side of the triangular notch on the T-shaped brake block 203c, and the limiting block 203i is connected to the limiting plate 203j by a spring.

[0046] This design, through ingenious mechanical construction, achieves precise control and graded response to wind speed changes. A triangular notch is specially designed on one side of each T-shaped brake block 203c to ensure that only one set of T-shaped brake blocks 203c can slide and participate in operation as needed when wind speed changes, corresponding to the current wind speed segment. Specifically, limit blocks 203i are fixedly installed around the periphery of the adjusting groove 203a. The orientation of these limit blocks 203i is deliberately arranged on the side corresponding to the triangular notch on the T-shaped brake block 203c, and they are connected to the limit plate 203j by springs, forming a flexible yet stable limiting mechanism.

[0047] In the design, the limiting strategies for different wind speed ranges (assuming they are divided into three levels: low, medium, and high) each have their own characteristics: In the high wind speed range, since the wind force is insufficient to directly drive the T-shaped brake block 203c, the limiting block 203i and the limiting plate 203j can be omitted outside the adjustment groove 203a in this range, allowing the T-shaped brake block 203c to slide freely. In the low wind speed range, the elasticity of the spring between the limiting plate 203j and the limiting block 203i outside the adjustment groove 203a matches the elasticity of the first spring 203b inside the adjustment groove 203a in the medium wind speed range. Similarly, the configuration of the medium-wind-speed section follows a similar logic, ensuring that when medium-wind speeds arrive, the wind force is sufficient to overcome the spring force of the first spring 203b in the previous wind-speed section (low-wind speed) and the spring force between the limiting plate 203j and the limiting block 203i. This allows the limiting plate 203j to slide along the slot direction, thereby pressing against the triangular notch on the T-shaped brake block 203c and preventing the T-shaped brake block 203c in the low-wind-speed section from meshing with the corresponding gear 203d. This ensures that only the brake blocks in the medium-wind-speed section can work effectively, achieving precise matching between wind speed and braking response. This design not only achieves automatic adjustment based on wind speed but also improves the system's stability and the accuracy of its response.

[0048] Example 2

[0049] Reference Figures 1-8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the reversing assembly 202 includes a first ratchet 202a rotatably connected to a fixed inner post within the wind vane 204; a first conical ratchet 202b engages with the outer wall of the first ratchet 202a; one end of the first conical ratchet 202b has a groove, and a ratchet support rod 202c, fixed to a rotating rod on the outer wall of the wind vane 204, slides within the groove; the inner wall of the grooved end of the first conical ratchet 202b engages with the first conical ratchet 202b; and the other end of the first conical ratchet 202b is fixed. It has teeth and meshes with the reversing gear 202d. The reversing gear 202d meshes with the second conical ratchet 202e. The second conical ratchet 202e meshes with the second ratchet 202f. The first ratchet 202a and the second ratchet 202f, and the second conical ratchet 202e and the first conical ratchet 202b are symmetrical. The second ratchet 202f is fixed to the lower half of the wind vane 204. The second conical ratchet 202e is connected to the rotating drum 202g through the ratchet support rod 202c. The rotating drum 202g is rotatably connected to the lower half of the wind vane 204.

[0050] In use, the rotation of the wind vane 204 drives the rotation of the outer wall rotating rod. Therefore, when the wind vane 204 rotates outward from the center of the louver 100, the rotation of the first conical ratchet 202b drives the first ratchet 202a to rotate on the fixed inner column inside the wind vane 204. At this time, the central fixed column section of the wind vane 204, which is fixed to the first ratchet 202a, rotates. This drives the second ratchet 202f to rotate, thereby driving the fixed inner column inside the wind vane 204 to operate. After being driven by the reversing gear 202d, the second conical ratchet 202e rotates in the opposite direction to the second conical ratchet 202e and the second ratchet 202f. The teeth of the second conical ratchet 202e and the second ratchet 202f continuously spring back when they encounter the teeth of the second ratchet 202f. When the wind vane 204 rotates outward from the center of the louver 100... When the first conical ratchet 202b rotates, it cannot drive the first ratchet 202a to rotate. However, the teeth of the first conical ratchet 202b meshing with the first ratchet 202a continuously bounce back when they encounter the teeth of the first ratchet 202a. When the direction of rotation of the wind vane 204 is outward from the center of the louver 100, the second conical ratchet 202e and the second ratchet 202f are in the same state. After passing through the reversing gear 202d, the rotation of the second conical ratchet 202e can drive the rotation of the second ratchet 202f. The rotation direction of the second ratchet 202f is always consistent, which in turn drives the fixed inner column inside the wind vane 204 to operate. This design ensures that no matter how the wind vane 204 rotates, the rotation direction of the fixed inner column inside the wind vane 204 is always consistent, thereby stably controlling the opening and closing of the blades of the dustproof ventilation device and maximizing the dustproof and ventilation effects.

[0051] Example 3

[0052] Reference Figures 1-8 This is the third embodiment of the present invention.

[0053] The main process includes: 1. Wind direction sensing and conversion: The wind vane 204 rotates with the wind direction, driving the outer wall rotating rod. Through the precision mechanical structure of the reversing assembly 202 (including the first ratchet 202a, the first conical ratchet 202b, the second conical ratchet 202e, the second ratchet 202f, etc.), it is ensured that no matter how the wind direction changes, the rotation direction of the fixed inner column in the wind vane 204 can be kept consistent through the conversion of the reversing gear 202d, thereby stably controlling the opening and closing of the blades.

[0054] 2. Wind Speed ​​Response and Adjustment: When the wind speed increases, the T-shaped brake block 203c corresponding to the wind speed level slides out of the adjustment groove 203a inside the wind vane 204 under the action of centrifugal force, overcoming the resistance of the first spring 203b. This action, through mechanical linkage of gears 203d, racks 203e, levers 203g, etc., drives the movable blade 103 to close or tilt in a timely manner, reducing the opening and effectively preventing dust. When the wind speed decreases, the brake block resets under the action of the first spring 203b, and the blades gradually return to normal ventilation.

[0055] 3. Dustproof and heat dissipation mechanism: In the dual-blade system, the fixed blade 102 is heavy and stable, while the movable blade 103 is lightweight and high-strength, made of carbon fiber reinforced plastic. The micro-serrated structure of the edges and the biomimetic airfoil design optimize dustproof and wind resistance performance. The movable blade 103 is connected by ropes to ensure coordinated overall movement and achieve a dynamic balance between dustproof and heat dissipation.
