Description

Technical Field

[0001] The invention belongs to the technical field of water collectors, in particular to a high-efficiency and energy-saving water collecting structure suitable for cooling towers. Background Art

[0002] The water collector in the closed cooling tower recovers excess moisture entrained in the hot and humid air discharged from the cooling tower. When the water collecting sheet contacts the warm and humid air flow and causes the water droplets in the air flow to move with the air flow, the water collecting sheet is intercepted and prevented from continuing to move with the air flow, thereby intercepting and capturing the water droplets, reducing water waste and the cooling tower's water replenishment needs, thereby achieving the purpose of saving water and preventing moisture from causing humidity to the environment around the closed cooling tower;

[0003] A Chinese patent with publication number CN119803162B discloses a closed cooling tower water collector with an adaptive angle-adjustable water collecting blade structure, comprising a lower mounting frame and an upper mounting frame. A guide bucket is fixedly connected to the inner side of the lower mounting frame, and an elastic bucket is mounted on the top of the guide bucket. The elastic bucket is a cylindrical component made of fluororubber material. An adjustment frame is provided on the outer side of the elastic bucket, and a water collecting frame is provided on the top of the elastic bucket. The top of the top water collecting frame is movably connected to the upper mounting frame. The present invention provides a closed cooling tower water collector with an adaptive angle-adjustable water collecting blade structure. The structure has the advantages of effectively utilizing the internal space of the cooling tower and guiding the rising warm and humid air flow, while adjusting according to the air flow rate and flow velocity. The angle of the water collecting blade can be flexibly adjusted as needed to optimize contact with the air flow and enhance flexibility during use.

[0004] In the current existing technology, when the cooling tower starts to exchange heat, the air flow carrying droplets will be driven by the fan at the top of the cooling tower, showing a migration route from the bottom of the tower to the top of the tower, and the water collector is used to intercept the air flow carrying droplets to reduce drifting water and reduce the waste of water resources. However, in actual application, when the fan is running at high power, the air flow speed increases. At this time, if the angle of the water collecting blade is too small, it will produce greater resistance to the air flow. Excessive resistance will lead to increased energy consumption of the fan. In severe cases, it may force the fan to reduce output, ultimately reducing the actual ventilation volume and affecting the efficiency of the cooling tower.

[0005] To this end, the present invention provides a high-efficiency and energy-saving water collection structure suitable for a cooling tower. Summary of the Invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, an embodiment of the present invention describes an efficient and energy-saving water collecting structure suitable for a cooling tower, comprising a frame 1, a synchronous bracket 23, a slider 3 and a water collecting blade 2 hinged in the frame 1; the middle part of the water collecting blade 2 is hinged to the frame 1 via a rotating shaft 21; the synchronous bracket 23 is arranged above the frame 1, and the ends of multiple water collecting blades 2 are all connected with a deflection shaft 2221, and multiple deflection shafts 2221 are equidistantly hinged to the synchronous bracket 23; the slider 3 is slidably connected to the corner of the frame 1, and the top of the slider 3 is provided with an inclined surface corresponding to the end of the synchronous bracket 23. When the slider 3 moves upward, the synchronous bracket 23 is squeezed to displace, and the synchronous bracket 23 drives multiple deflection shafts 2221 to rotate around the corresponding rotating shaft 21 to drive multiple water collecting blades 2 to adjust their angles.

[0036] When the cooling tower starts to exchange heat, the airflow carrying droplets will be driven by the fan at the top of the cooling tower, showing a migration route from the bottom of the tower to the top of the tower. The water collector is used to intercept the airflow carrying droplets to reduce drifting water and reduce the waste of water resources. However, in actual application, when the fan is running at high power, the airflow speed increases. At this time, if the angle of the water collecting blade is too small, it will produce greater resistance to the airflow. Excessive resistance will increase the energy consumption of the fan. In severe cases, it may force the fan to reduce its output, ultimately reducing the actual ventilation volume and affecting the efficiency of the cooling tower.

[0037] Based on the existing water collecting device structure, in one embodiment of the present invention, a plurality of water collecting blades 2 are arranged in an array at the same angle in a frame 1, and the middle portion of the water collecting blade 2 is hinged to the frame 1 via a rotating shaft 21 to meet the rotation requirements of the water collecting blade 2. At the end of the water collecting blade 2, that is, the position on the water collecting blade 2 away from the rotating shaft 21, a deflection shaft 2221 passes through. At the same time, the deflection shafts 2221 on the plurality of water collecting blades 2 are hinged to a synchronous bracket 23. That is, based on the above setting, when it is necessary to adjust the angle of the water collecting blade 2, the synchronous bracket 23 can be moved to cause the plurality of water collecting blades 2 to be synchronously deflected by a certain angle, thereby coping with high / low wind speeds and realizing adaptive adjustment of the water collecting device in the cooling tower.

[0038] As mentioned above, for the above-mentioned water collector structure, based on the adjustment of the synchronous bracket 23, the angles of multiple water collecting blades 2 can be adjusted synchronously to meet the needs of high / low wind speeds. In addition, in one embodiment, high and low wind speeds correspond to fixed thresholds. It can be understood that when the airflow speed exceeds the threshold or is lower than the threshold, the slider 3 used to drive the displacement of the synchronous bracket 23 will move up or reset. Specifically, in one embodiment, when the airflow speed exceeds the threshold, the slider 3 will move up, and in the process of the slider 3 moving up, the inclined surface of the slider 3 relative to the synchronous bracket 23 can slide relative to the end of the synchronous bracket 23, causing the synchronous bracket 23 to be passively displaced. The passive displacement of the synchronous bracket 23 will drive the deflection of multiple water collecting blades 2, thereby changing the angle of the water collecting blade 2. It can be understood that in the initial state, the angle of the water collecting blade 2 is larger, and the collision area when the airflow passes through the water collecting blade 2 is larger. Therefore, when the high-speed airflow passes through, it will be hindered to a certain extent, affecting the airflow rate, which in turn leads to an increase in fan energy consumption, which is not conducive to improving the efficiency of the cooling tower. Therefore, when the high-speed airflow passes through, the slider 3 moves up, driving the synchronous bracket 23 to move, so that the multiple water collecting blades 2 are deflected and the angle is reduced. At this time, the collision area between the airflow and the water collecting blades 2 is reduced, which is conducive to the rapid passage of high-speed airflow and avoids the increase in fan energy consumption; among them, when the high-speed airflow passes through, reducing the angle and collision area of ​​the water collecting blades 2 may essentially not be able to fully intercept the airflow carried in the airflow, but if a larger collision area is maintained, the gap between the airflow and the water collecting blades 2 is too narrow, and the airflow speed through the water collecting blades 2 will be further increased. At this time, on the one hand, it will affect the fan energy consumption, and on the other hand, the excessively high airflow speed will cause tiny water droplets that should have been intercepted to "rush" through the gap or be entrained again.

[0039] like Figures 1 to 2 、 Figure 8 、 Figure 9 As shown, a back plate 31 is fixedly connected to one side of the slider 3, and a connecting rod 35 is slidably connected to the back plate 31, one end of the connecting rod 35 passes through the back plate 31 and is locked by a nut 37; the other end of the connecting rod 35 is fixedly connected to a stopper 34; a movable groove 36 corresponding to the stopper 34 is provided in the slider 3, and the stopper 34 is slidably connected in the movable groove 36; when the inclined surface at the top of the slider 3 and the inclined surface at the end of the synchronous bracket 23 slide relative to each other, and the synchronous bracket 23 is passively displaced to the bottom of the inclined surface of the slider 3, the stopper 34 slides out of the movable groove 36, preventing the synchronous bracket 23 from resetting.

[0040] The slider 3 moves upward and squeezes the synchronous bracket 23 to move, so that the angle of the water collecting blade 2 is reduced, and the collision area with the airflow is reduced. At the same time, in order to prevent the synchronous bracket 23 from resetting immediately after moving, in one embodiment of the present invention, after the slider 3 and the synchronous bracket 23 slide relative to each other, the position change of the slider 3 and the synchronous bracket 23 is changed from the original synchronous bracket 23 being located above the slider 3 to the slider 3 being located above the synchronous bracket 23. At this time, the stopper 34 inside the slider 3 parallel to the synchronous bracket 23 will extend out of the movable groove 36 and prevent the synchronous bracket 23 from resetting. It can be understood that when the slider 3 and the end of the synchronous bracket 23 slide relative to each other, and the synchronous bracket 23 is displaced to the slider 3, the angle of the water collecting blade 2 is adjusted to be small. At this time, the high-speed airflow can pass through the water collecting blade 2 quickly, avoiding increasing the energy consumption of the fan and avoiding secondary entrainment of the tiny water droplets that should have been intercepted. At the same time, in order to adapt to the high-speed airflow and prevent the synchronous bracket 23 from resetting immediately, after the slider 3 moves to the top of the synchronous bracket 23, the block 34 located inside it can drive the connecting rod 35 to move until the block 34 slides out of the movable groove 36 and limits the synchronous bracket 23 to prevent the synchronous bracket 23 from resetting. At this time, the synchronous bracket 23 will always remain in the state of being located below the slider 3. Correspondingly, the multiple water collecting blades 2 also maintain the adjusted small angle to adapt to the high-speed airflow.

[0041] like Figures 8 and 9 As shown, a through hole is provided inside the slider 3, and a center shaft 38 is slidably connected in the through hole; a clearance groove 381 is provided on the top of the center shaft 38 for avoiding the connecting rod 35; a first waist circular groove 33 is provided on the outer wall of the slider 3, and a second waist circular groove 382 is correspondingly provided on the side wall of the center shaft 38; a pin shaft 32 is connected through the side wall of the slider 3, and the pin shaft 32 passes through the first waist circular groove 33 and the second waist circular groove 382 in sequence.

[0042] like Figures 1 to 3 、 Figure 7 As shown, it also includes an I-shaped bracket 4; the top of the I-shaped bracket 4 is slidably connected to a plurality of synchronization rods 42, and the synchronization rods 42 are used to drive the slider 3 to move upward; the middle part of the I-shaped bracket 4 is connected through a vertical shaft 44, and the bottom of the vertical shaft 44 is rotatably connected to the fan blade 5; a limiting member is also provided at the bottom of the frame 1, and the limiting member is used to limit the upward movement of the I-shaped bracket 4; the four corners of the frame 1 are also fixed with a second spring 14, and the second spring 14 is used to drive the I-shaped bracket 4 to move upward; when the wind speed exceeds the threshold, the fan blade 5 is lifted and drives the vertical shaft 44 to squeeze the limiting member, and the I-shaped bracket 4 moves upward under the action of the second spring 14.

[0043] like Figures 1 to 4 、 Figure 6As shown, the synchronization bracket 23 is provided with an inclined surface at one end relative to the slider 3, and the inclined surface corresponds to the inclined surface at the top of the slider 3. The stopper 34 is a vertical plane at one end relative to the synchronization bracket 23, and the other end is provided with an inclined surface. A through shaft is fixedly connected to the position corresponding to the slider 3 on the synchronization rod 42, and the through shaft squeezes the central shaft 38 as the synchronization rod 42 moves upward. The central shaft 38 moves upward to squeeze the inclined surface on the stopper 34, driving the stopper 34 to slide outward and preventing the synchronization bracket 23 from resetting.

[0044] In one embodiment, in the initial state of the slider 3, the pin shaft 32 passing through the middle is overlapped on the frame 1. When the slider 3 is passively moved upward, the pin shaft 32 will be driven to move together. It is worth noting that the through hole opened in the slider 3 is also slidably connected to the center shaft 38, and when the center shaft 38 moves upward with the slider 3, it can avoid the connecting rod 35 at one end of the block 34 based on the give way groove 381 at its top to avoid movement interference; wherein, when the I-shaped bracket 4 moves upward, it will drive multiple synchronization rods 42 to move upward. When multiple synchronization rods 42 move upward, they can be inserted into the through hole inside the slider 3 based on the interlaced shaft on the synchronization rod 42, and at the same time squeeze the center shaft 38 to move upward. That is to say, when the slider 3 and the synchronization bracket 23 slide relative to each other, and the slider 3 is just located at When the cam 35 is in the upward direction, the stopper 34 is pressed against the top of the cam 35 and the stopper 34 is pressed against the top of the cam 35. When the cam 35 is in the upward direction, the stopper 34 is pressed against the top of the cam 35 and the stopper 34 is pressed against the top of the cam 35. When the cam 35 is in the upward direction, the stopper 34 is pressed against the top of the cam 35 and the stopper 34 is pressed against the top of the cam 35.

[0045] In addition, in one embodiment, the fan blades 5 can generate an upward lift when a high-speed airflow passes through, and when the fan blades 5 move upward, they can drive the vertical shaft 44 to squeeze the limit piece, so that the limit piece is separated from the I-shaped bracket 4. At this time, the second spring 14 compressed in the initial state releases the elastic force, driving the I-shaped bracket 4 to move upward, thereby driving the synchronization rod 42 to move upward, realizing the function of squeezing the displacement of the synchronization bracket 23 and using the stopper 34 to limit and block the reset of the synchronization bracket 23; it is worth noting that in the initial state, when the airflow speed is low, the total weight of the fan blades 5 and the I-shaped bracket 4 is greater than the elastic force of the second spring 14. Therefore, when the airflow speed is low, the total gravity of the fan blades 5 and the I-shaped bracket 4 will drive the I-shaped bracket 4 to reset downward, and the slider 3 will also reset at this time. When the airflow speed is high, that is, when dealing with high-speed airflow, the fan blades 5 are affected by the airflow. At this time, the lift is greater than the gravity, and the gravity of the I-shaped bracket 4 alone is not enough to squeeze the second spring 14 to compress it. Then, under the action of the elastic force of the second spring 14, the I-shaped bracket 4 will be driven to move upward, thereby driving the synchronization rod 42 to move upward.

[0046] like Figures 1 to 3 、 Figure 7 As shown, the bottom of the frame 1 is fixedly connected to an L-shaped fixed plate 15, and the limit member is slidably connected to the fixed plate 15; the limit member includes a clamping block 16 and a third spring 162; the tail of the clamping block 16 is slidably connected to the fixed plate 15; the middle of the clamping block 16 is fixedly connected to a baffle 161, the third spring 162 is sleeved on the clamping block 16, and the two ends are respectively fixed to the fixed plate 15 and the baffle 161.

[0047] In one embodiment, a limit member is provided on the fixed plate 15, and the block 16 is in an extended state in the initial state due to the elastic force of the third spring 162, and the two symmetrically arranged limit members work together to limit and block the I-shaped bracket 4 from moving upward. Even if the gravity of the I-shaped bracket 4 is not enough to offset the elastic force of the second spring 14 at this time, the I-shaped bracket 4 cannot break through the restriction and move upward due to the restriction of the limit member. When the fan blade 5 drives the vertical axis 44 to squeeze the two symmetrically arranged blocks 16, so that the block 16 is separated from the I-shaped bracket 4, the I-shaped bracket 4 will move upward under the elastic force of the second spring 14, thereby driving the synchronization rod 42 to move upward, and finally realizing the slider 3 squeezing the synchronization bracket 23 to move, and multiple water collecting blades 2 are deflected, so that the collision area between the high-speed airflow and the water collecting blades 2 is reduced, thereby avoiding increased energy consumption of the fan.

[0048] like Figures 1 to 3 、 Figure 7As shown, a slope block 43 is provided in the middle of the I-type bracket 4, and the slope block 43 corresponds to the block 16, the vertical axis 44 passes through the middle of the slope block 43, and the top of the vertical axis 44 is fixedly connected to the limit plate 441, and the bottom of the vertical axis 44 is fixedly connected to the first circular plate 442 and the second circular plate 443, and the first circular plate 442 and the second circular plate 443 are arranged at intervals; the fan blade 5 is rotatably connected between the first circular plate 442 and the second circular plate 443; when the wind speed exceeds the threshold, the fan blade 5 squeezes the second circular plate 443 to move upward, drives the vertical axis 44 to move upward and squeezes the symmetrically arranged blocks 16, and the limit of the I-type bracket 4 is cancelled.

[0049] In one embodiment, the block 16 extends to the top of the slope block 43 under the elastic force of the third spring 162, thereby limiting the I-shaped bracket 4. When the fan blade 5 generates lift under the drive of the high-speed airflow, and the lift is greater than the self-weight of the fan blade 5, the fan blade 5 will squeeze the second circular plate 443 and drive the second circular plate 443 to move upward, and drive the vertical shaft 44 to move upward. The upward movement of the vertical shaft 44 will squeeze the block 16, thereby causing the block 16 to shrink. At this time, the I-shaped bracket 4 only relies on its own weight and cannot limit the second spring 14. Under the elastic force of the second spring 14, the I-shaped bracket 4 can be driven to move upward, and the synchronization rod 42 can be squeezed synchronously, so that the synchronization rod 42 can drive the slider 3 to move upward, thereby realizing the function of squeezing the synchronization bracket 23 to move.

[0050] like Figures 1 to 2 As shown, the four corners of the frame 1 are fixed with partitions 12, and the partitions 12 are fixed with vertical rods 13, the second spring 14 is sleeved on the vertical rods 13, and the four corners of the I-shaped bracket 4 are respectively slidably connected to the corresponding vertical rods 13; the two ends of the second spring 14 are respectively fixed between the I-shaped bracket 4 and the partition 12.

[0051] like Figures 1 to 2 、 Figure 7 As shown, a fixing frame 11 is fixed to the top of the frame 1, and the fixing frame 11 is arranged adjacent to the slider 3. A sliding rod 112 is slidably connected to the fixing frame 11, and a reset plate 111 is fixed to the end of the sliding rod 112. A first spring 113 is sleeved on the sliding rod 112, and the two ends of the first spring 113 are respectively fixed between the inner side of the fixing frame 11 and the reset plate 111; the reset plate 111 and the first spring 113 are used to buffer the synchronous bracket 23 and drive the synchronous bracket 23 to reset.

[0052] In one embodiment, when the wind speed decreases, that is, when dealing with low-speed airflow, the lift of the fan blade 5 is less than its own weight. Under the total gravity of the fan blade 5 and the I-shaped bracket 4, the second spring 14 is squeezed and compressed, and the I-shaped bracket 4 and the fan blade 5 are reset to the initial state. At this time, the slider 3 is no longer subjected to force and will produce a downward reset action. Since the block 34 is extended out of the movable groove 36 based on the squeezing of the central axis 38, during the process of the slider 3 resetting downward, the block 34 can be driven to retract the movable groove 36 based on the reset spring. At this time, based on the reset plate 111 and the first spring 113, the synchronous bracket 23 can be driven to reset, and the multiple water-collecting blades 2 can be driven to reset to the initial state.

[0053] like Figures 1 to 2 、 Figure 7 As shown, a limit rod 41 is fixed to the I-shaped bracket 4 , and one end of the synchronization rod 42 is slidably connected to the limit rod 41 , and the other end of the synchronization rod 42 corresponds to the slider 3 .

[0054] Working principle: Based on the existing water collecting device structure, multiple water collecting blades 2 are arranged in an array at the same angle in the frame 1, and the middle part of the water collecting blade 2 is hinged to the frame 1 via the rotating shaft 21 to meet the rotation requirements of the water collecting blade 2. At the end of the water collecting blade 2, that is, the position on the water collecting blade 2 away from the rotating shaft 21, a deflection shaft 2221 passes through. At the same time, the deflection shafts 2221 on the multiple water collecting blades 2 are hinged to the synchronous bracket 23. That is to say, based on the above setting, when the angle of the water collecting blade 2 needs to be adjusted, the synchronous bracket 23 can be moved to cause the multiple water collecting blades 2 to be synchronously deflected by a certain angle, thereby coping with high / low wind speeds and realizing adaptive adjustment of the water collecting device in the cooling tower.

[0055] As mentioned above, for the above-mentioned water collector structure, based on the adjustment of the synchronous bracket 23, the angles of multiple water collecting blades 2 can be adjusted synchronously to meet the needs of high / low wind speeds. In addition, high and low wind speeds correspond to fixed thresholds. It can be understood that when the airflow speed exceeds the threshold or is lower than the threshold, the slider 3 used to drive the displacement of the synchronous bracket 23 will move up or reset. Specifically, when the airflow speed exceeds the threshold, the slider 3 will move up, and in the process of the slider 3 moving up, the inclined surface of the slider 3 relative to the synchronous bracket 23 can slide relative to the end of the synchronous bracket 23, causing the synchronous bracket 23 to be passively displaced. The passive displacement of the synchronous bracket 23 will drive the deflection of multiple water collecting blades 2, thereby changing the angle of the water collecting blade 2. It can be understood that in the initial state, the angle of the water collecting blade 2 is large, and the collision area when the airflow passes through the water collecting blade 2 is large. Therefore, at high speeds When the airflow passes through, it will be hindered to a certain extent, affecting the airflow rate, which in turn leads to increased fan energy consumption and is not conducive to improving the efficiency of the cooling tower. Therefore, when the high-speed airflow passes through, the slider 3 moves upward, driving the synchronous bracket 23 to move, so that the multiple water collecting blades 2 are deflected and the angle is reduced. At this time, the collision area between the airflow and the water collecting blades 2 is reduced, which is conducive to the rapid passage of high-speed airflow and avoids the increase of fan energy consumption; Among them, when the high-speed airflow passes through, reducing the angle and collision area of ​​the water collecting blades 2 may not essentially achieve sufficient interception of the airflow carried in the airflow, but if a larger collision area is maintained, the gap between the airflow and the water collecting blades 2 is too narrow, and the airflow speed through the water collecting blades 2 will be further increased. At this time, on the one hand, it will affect the fan energy consumption, and on the other hand, the excessively high airflow speed will cause tiny water droplets that should have been intercepted to "rush" through the gap or be entrained again;

[0056] The slider 3 moves upward and squeezes the synchronous bracket 23 to move, so that the angle of the water collecting blade 2 is reduced, and the collision area with the airflow is reduced. At the same time, in order to prevent the synchronous bracket 23 from resetting immediately after moving, in one embodiment of the present invention, after the slider 3 and the synchronous bracket 23 slide relative to each other, the position change of the slider 3 and the synchronous bracket 23 is changed from the original synchronous bracket 23 being located above the slider 3 to the slider 3 being located above the synchronous bracket 23. At this time, the stopper 34 inside the slider 3 parallel to the synchronous bracket 23 will extend out of the movable groove 36 and prevent the synchronous bracket 23 from resetting. It can be understood that when the slider 3 and the end of the synchronous bracket 23 slide relative to each other, and the synchronous bracket 23 is displaced to the slider 3, the angle of the water collecting blade 2 is adjusted to be small. At this time, the high-speed airflow can pass through the water collecting blade 2 quickly, avoiding increasing the energy consumption of the fan and avoiding secondary entrainment of the tiny water droplets that should have been intercepted. At the same time, in order to adapt to the high-speed airflow and prevent the synchronous bracket 23 from resetting immediately, after the slider 3 moves to the top of the synchronous bracket 23, the block 34 located inside it can drive the connecting rod 35 to move until the block 34 slides out of the movable groove 36 and limits the synchronous bracket 23 to prevent the synchronous bracket 23 from resetting. At this time, the synchronous bracket 23 will always remain in the state of being located below the slider 3. Correspondingly, the multiple water collecting blades 2 also maintain the adjusted small angle to adapt to the high-speed airflow.

[0057] When the slider 3 is in the initial state, the pin shaft 32 passing through the middle is overlapped on the frame 1. When the slider 3 is passively moved upward, the pin shaft 32 will be driven to move together. It is worth noting that the through hole opened in the slider 3 is also slidably connected to the center shaft 38, and when the center shaft 38 moves up with the slider 3, it can avoid the connecting rod 35 at one end of the block 34 based on the give way groove 381 at its top to avoid movement interference; wherein, when the I-shaped bracket 4 moves upward, it will drive multiple synchronization rods 42 to move upward. When multiple synchronization rods 42 move upward, they can be inserted into the through hole inside the slider 3 based on the interlaced shaft on the synchronization rod 42, and at the same time squeeze the center shaft 38 to move upward, that is, when the slider 3 and the synchronization bracket 23 slide relative to each other, and the slider 3 is just located at the synchronization bracket The stopper 34 is pressed against the top of the lever 35 and the lever 36 is engaged, and the stopper 34 is pressed against the top of the lever 35. When the lever 35 is engaged, the stopper 34 is engaged, and the lever 36 is engaged.

[0058] In addition, when the high-speed airflow passes through, the fan blades 5 can generate an upward lift, and when the fan blades 5 move upward, they can drive the vertical shaft 44 to squeeze the limit piece, so that the limit piece is separated from the I-shaped bracket 4. At this time, the second spring 14 compressed in the initial state releases the elastic force, driving the I-shaped bracket 4 to move upward, thereby driving the synchronization rod 42 to move upward, realizing the function of squeezing the displacement of the synchronization bracket 23 and using the stop block 34 to limit and block the reset of the synchronization bracket 23; it is worth noting that in the initial state, when the airflow speed is low, the total weight of the fan blades 5 and the I-shaped bracket 4 is greater than the elastic force of the second spring 14. Therefore, when the airflow speed is low, the total gravity of the fan blades 5 and the I-shaped bracket 4 will drive the I-shaped bracket 4 to reset downward, and the slider 3 will also reset at this time. When the airflow speed is high, that is, when dealing with high-speed airflow, the fan blades 5 are affected by the airflow. At this time, the lift is greater than the gravity, and the gravity of the I-shaped bracket 4 alone is not enough to squeeze the second spring 14 to compress it. Under the action of the elastic force of the second spring 14, the I-shaped bracket 4 will be driven to move upward, thereby driving the synchronization rod 42 to move upward.
