Description

Technical Field

[0001] The present application relates to the field of fluid filtration, and in particular to a fluid filtration structure and a pipeline having the structure. Background Art

[0002] Downspouts are mainly used to collect rainwater from the roof and connect it to the drainage ditch below.

[0003] A filter device is usually installed on the downpipe to filter impurities such as leaves. The current filter device usually includes a box body with a filter installed in the box body. During the long-term filtering operation, a large number of impurities such as leaves accumulate on the filter, which will clog the mesh of the filter, thereby reducing the flow efficiency of the fluid. Summary of the invention

[0004] In order to ensure the circulation efficiency of the fluid, the present application provides a fluid filtering structure and a pipeline having the structure.

[0005] The present application provides a fluid filtering structure and a pipeline having the structure using the following technical solutions:

[0006] A fluid filtering structure comprises a box body in a rectangular parallelepiped shape, wherein both upper and lower sides of the box body are provided with mounting plates for connecting with a pipeline, a side wall of the box body is provided with an avoidance port, an outer wall of the box body is provided with a storage bin connected with the avoidance port, a linkage shaft is rotatably provided at the avoidance port of the box body, and a driving motor for driving the linkage shaft to rotate is provided on the box body; four filter plates are arranged in a peripheral array of the linkage shaft, a filter net is provided in the middle part of the filter plate, and the filter net filters the fluid entering the box body; four plug-in slots are provided on the linkage shaft, corresponding to the filter plates one by one, the end of the filter plate is located in the plug-in slot, the filter plate slides in the plug-in slot, a compression spring is provided in the plug-in slot of the linkage shaft, one end of the compression spring is connected to the filter plate, and the other end of the compression spring is connected to the inner wall of the plug-in slot, and a pressure sensor is installed on the bottom wall of the plug-in slot of the linkage shaft, and when the pressure sensor is subjected to the pressure of the filter plate, the pressure sensor transmits a signal to the driving motor, and the driving motor drives the linkage shaft to rotate 90 degrees.

[0007] By adopting the above technical solution, four filter plates are arranged in the box body. In the initial state, one of the filter plates is located in the box body to play a filtering role, two filter plates block the avoidance port, and another filter plate is located in the containing bin. When rainwater enters the box body, the filter net filters impurities such as leaves. When the accumulation of leaves gradually increases, the leaves will block the filter holes, resulting in a decrease in the flow efficiency of rainwater. Rainwater will accumulate on the upper side of the filter plate. When the accumulation amount increases, the pressure on the filter plate will also increase accordingly. When the gravity reaches a certain level, the filter plate drops and contacts the pressure sensor. At this time, the pressure sensor transmits a signal to the drive motor, and the drive motor drives the linkage shaft to rotate 90 degrees, that is, the filter plate located in the box body rotates 90 degrees and is in a vertical state. At this time, leaves and other debris will fall into the containing bin, and then the next pass The filter plate rotates horizontally and enters the box, at which time it performs a filtering operation. At this time, there is no debris on the filter plate, thereby ensuring the circulation efficiency of rainwater; that is, the filter plate is rotated by gravity generated by the accumulation of rainwater, and the filter plate can be continuously replaced to ensure the circulation efficiency of rainwater; in addition, there is no accumulation of leaves on the filter plate in the box or the accumulation is small. When the amount of rainwater is large and turbulent, the rainwater cannot flow downward from the filter net in time, and the rainwater will also accumulate. When the weight generated by the accumulation is large, the filter plate will slide downward and contact with the pressure sensor, so that the linkage shaft drives the filter plate to rotate. In the process of the filter plate rotating from a horizontal state to a vertical state, there will gradually be an unobstructed flow gap between the filter plate and the box, and part of the rainwater will also be diverted from the storage bin, thereby ensuring rapid drainage in the case of turbulent rainwater.

[0008] Preferably, a driving bin is installed on the outer wall of the box body, the end of the linkage shaft extends into the driving bin, the driving motor is installed in the driving bin, a one-way wheel is coaxially fixed on the linkage shaft, a pawl is rotatably connected to the one-way wheel, a ratchet is fixedly provided on the inner wall of the accommodating bin, the ratchet is located on the circumferential side of the one-way wheel, the pawl and the ratchet teeth of the ratchet are meshed with each other, an abutment spring is provided on the one-way wheel, one end of the abutment spring is connected to the one-way wheel, and the other end of the abutment spring is connected to the pawl.

[0009] By adopting the above technical solution, when the gravity is large, the filter plate may drive the linkage shaft to rotate downward. Therefore, through the cooperation of the pawl and the ratchet, the linkage shaft can only move in one direction, which can prevent the linkage shaft from rotating downward, thereby ensuring that the filter plate can be replaced smoothly.

[0010] The filament filter cloth is connected with a first end of the filter cloth and a second end of the filter cloth is connected with a first end of the filter cloth to form a through hole, and a second end of the filter cloth is connected with a second end of the filter cloth to form a through hole.

[0011] By adopting the above technical solution, when the gravity on the filter plate is large, the filter plate in the box body rotates upward to a vertical state. At this time, the scraper does not move. When the vertical filter plate rotates to a horizontal state in the accommodating bin, the driving member drives the first connecting shaft to rotate, and the first pulley on the first connecting shaft drives the second pulley to rotate through the belt. The second pulley drives the winding wheel to rotate through the first connecting shaft, and the winding wheel winds the pull rope, thereby driving the scraper to slide, thereby realizing the removal of leaves from the surface of the filter net.

[0012] Preferably, the driving member is configured as a rack, and the rack is in the shape of a quarter arc. The end of the first connecting shaft extends out of the filter plate and the end of the linkage shaft from the plug-in slot. A gear is coaxially fixed to the end of the first connecting shaft. When the filter plate is rotated upward to a vertical state, the gear just meshes with the rack. When the filter plate is rotated into the accommodating bin to a horizontal state, the gear meshes with the end of the rack.

[0013] By adopting the above technical solution, when the filter plate rotates upward from a horizontal state in the box to a vertical state, the gear just meshes with the rack, and then the filter plate continues to rotate. Under the action of the rack, the gear rotates, which can drive the first connecting shaft to rotate, thereby realizing the movement of the scraper. When the filter plate is in a horizontal state in the accommodating bin, the ends of the gear and the rack mesh, and the filter plate continues to rotate to a vertical state and is located below the linkage shaft. During this process, the gear and the rack disengage, and under the action of the coil spring, the pull rope is reset, which drives the scraper to quickly reset.

[0014] Preferably, the linkage shaft is provided with a baffle between adjacent filter plates, and the baffle and the adjacent filter plates are arranged at an angle of 45 degrees; an extension groove is opened on the scraper plate, the scraper is slidably connected with an extension plate in the extension groove, the scraper is provided with a return spring in the extension groove, one end of the return spring is connected to the inner wall of the extension groove, the other end of the return spring is connected to the extension plate, and the end of the extension plate is wedge-shaped; in the initial state, the extension plate is in a compressed state and the end of the extension plate abuts against the baffle.

[0015] By adopting the above technical solution, when the filter plate rotates to the upper side of the linkage shaft and is in a vertical state, the leaves on the filter net will fall downward due to gravity. Because the leaves are relatively wet, they have a certain gravity and will not float. Therefore, most of the leaves will accumulate on the baffle and the scraper. When the filter plate rotates again, that is, rotates horizontally into the containing bin, the scraper will drive the leaves to move to the side away from the linkage shaft. In this process, the leaves will fall toward the inner wall of the containing bin in a parabolic state, thereby preventing them from falling onto the filter net on the lower side. In practice, when the filter plate is located on the upper side of the linkage shaft and is in a vertical state, some relatively dry leaves will fall onto the filter plate on the lower side. This filter plate is for the water in the containing bin. The filter plate is in a flat state, and the weight of the leaves is relatively low. When the filter plate rotates downward to a vertical state, the gear and the rack are disengaged, and the pull rope is reset under the action of the coil spring, which drives the scraper to reset quickly. The scraper can clean the surface of the filter again, and because the scraper is quickly reset, when the scraper is reset, the sliding block collides with the end of the sliding groove, generating a certain vibration force, causing the filter to vibrate, and then the leaves on the upper surface of the filter can be shaken off into the receiving bin, thereby ensuring the cleanliness of the filter surface; when the scraper slides away from the linkage shaft, the extension plate will gradually extend outward to expand the area, so as to further support the leaves and prevent the leaves from falling directly onto the filter below.

[0016] Preferably, the accommodating bin is formed with an arc plate at the lower side of the avoidance opening, the trajectory of the arc plate is the same as the rotation trajectory of the filter plate, and a drop opening is formed between the upper end of the arc plate and the inner wall of the accommodating bin.

[0017] By adopting the above technical scheme, and due to the setting of the arc plate, the accommodating space of the accommodating bin extends from the lower side of the avoidance opening to the upper end of the arc plate, thereby expanding the accommodating space; during the rotation of the filter plate and the movement of the scraper, the leaves will enter the bottom of the accommodating bin from the drop opening; when the rainwater is relatively turbulent, the filter plate will be in a state of continuous rotation, a large amount of rainwater will pass through and enter the accommodating bin, and a part of the rainwater will flow downward from the filter net, and finally fall on the arc plate and be discharged, and during the rotation of the filter plate, when the two filter plates on the upper side are in a V-shaped state, the rainwater will directly rush into the accommodating bin, and then as the filter plate rotates, the rainwater hits the inner wall of the accommodating bin, and then part of the rainwater falls on the arc plate after the collision and is discharged, and part of the rainwater enters the bottom of the accommodating bin from the drop opening; that is, through the setting of the arc plate, in the case of turbulent rainwater, it can help to guide the rainwater to be discharged as much as possible, to prevent the rainwater from entering the accommodating bin and accumulating quickly, and drive the leaves into the rotating area of ​​the filter plate.

[0018] Preferably, a bottom cover is detachably mounted on the bottom of the accommodating bin.

[0019] By adopting the above technical solution, the bottom cover can be removed regularly to clean the impurities accumulated in the storage bin.

[0020] A pipeline comprises a pipe body and the above-mentioned fluid filtering structure, wherein the fluid filtering structure is installed on the vertical part of the pipe body, a plurality of through holes are opened on the mounting plate, and the through holes of the mounting plate and the pipe body are fixedly connected by bolts.

[0021] By adopting the above technical solution, a fluid filtering structure is installed in the pipeline, which can prevent blockage by leaves and affect the flow efficiency of rainwater on the one hand, and can achieve rapid drainage of rainwater in the case of turbulent rainwater on the other hand.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Using the four filter plates rotating in the box, when blockage occurs and rainwater is not discharged in time, the gravity of rainwater on the filter plate will gradually increase, thereby driving the filter plate to slide downward in the plug-in slot. When the filter plate contacts the pressure sensor, the pressure sensor transmits a signal to the drive motor and drives the linkage shaft to rotate 90 degrees, so that the subsequent clean filter plate can be replaced, thereby ensuring the circulation efficiency of rainwater;

[0024] 2. When the rain is turbulent, due to the setting of the filter screen, the rain will not be discharged in time. The increased weight of the rain will drive the filter plate down, and then the linkage shaft will rotate to realize the rotation of the filter plate. When the filter plate rotates, an unobstructed flow gap will be formed between the filter plate and the box, and part of the rain will enter the storage chamber from the avoidance port, thereby improving the drainage efficiency of the rain and preventing the drainage efficiency of the rain from decreasing due to the turbulence of the rain.

[0025] 3. When the filter plate rotates from a vertical state to a horizontal state in the receiving bin, the scraper slides on the surface of the filter plate to scrape off the leaves and impurities on the surface of the filter screen, thereby cleaning the filter plate. When the filter plate continues to rotate, the gear and then the rack are disengaged. Under the action of the coil spring, the scraper will quickly reset, and will hit the filter plate when resetting, causing the filter screen to vibrate. At this time, the filter plate is tilted, so the vibration can cause impurities such as leaves to fall from the filter screen, further improving the cleaning effect of impurities.

[0026] 4. With the cooperation of the baffle and the scraper, when the filter plate rotates to a vertical state, the leaves on its surface will not fall directly into the receiving bin, but will accumulate on the baffle and the scraper, thereby preventing the leaves from falling on the filter plate in a horizontal state in the receiving bin, which increases the difficulty of cleaning. When the scraper moves subsequently, the extension plate will extend to further expand the supporting area to prevent the leaves from falling. When the filter plate rotates, the scraper moves, which can make the leaves and other impurities fall out smoothly from the drop port along the parabolic direction, which helps to prevent the leaves and other impurities from falling on the filter plate at the lower side.

[0027] 5. The setting of the arc plate, on the one hand, extends upward from the lower end of the avoidance port, thereby increasing the storage space at the bottom of the storage bin. On the other hand, when the rainwater is relatively turbulent, the filter plate will be in a state of continuous rotation, and a large amount of rainwater will pass through and enter the storage bin, and part of the rainwater will flow downward from the filter net, and finally fall on the arc plate and be discharged. In the process of rotation of the filter plate, when the two filter plates on the upper side are in a V-shaped state, the rainwater will directly rush into the storage bin, and then as the filter plate rotates, the rainwater hits the inner wall of the storage bin, and then part of the rainwater falls on the arc plate after the collision and is discharged, and part of the rainwater enters the bottom of the storage bin from the drop port. That is, through the setting of the arc plate, in the case of turbulent rainwater, it can help to guide the rainwater to be discharged as much as possible, to prevent the rainwater from entering the storage bin and accumulating quickly, and driving the leaves into the rotating area of ​​the filter plate.

[0040] The following is combined with Figure 1 -Attached Fig.11 This application is described in further detail.

[0041] The embodiments of the present application disclose a fluid filtering structure and a pipeline having the structure.

[0042] Reference Figure 1 , Figure 2 and Figure 3The fluid filtering structure includes a box body 1 in a rectangular shape, and mounting plates 11 are integrally formed on the upper and lower sides of the box body 1. The mounting plates 11 are used to connect with the pipeline. A avoidance opening 12 is opened on the side wall of the box body 1, and a storage bin 2 is integrally formed on the side wall of the box body 1. The storage bin 2 is connected with the avoidance opening 12. The box body 1 is rotatably provided with a linkage shaft 3 at the avoidance opening 12, and a driving motor 4 for driving the linkage shaft 3 to rotate is provided on the box body 1; four filter plates 5 are arranged in a circumferential array along the circumference of the linkage shaft 3, and a filter plate 5 is installed in the middle of the filter plate 5. The filter screen 51 filters rainwater; the linkage shaft 3 is provided with four plug-in slots 31, which correspond to the filter plates 5 one by one. The ends of the filter plates 5 are plugged into the plug-in slots 31, and the filter plates 5 slide in the plug-in slots 31. The linkage shaft 3 is located in the plug-in slots 31 and is fixedly connected with a guide rod 311. The filter plates 5 are plugged and slidably matched with the guide rod 311. The linkage shaft 3 is located in the plug-in slots 31 and is installed with a compression spring 32. One end of the compression spring 32 is connected to the filter plate 5, and the other end is connected to the inner wall of the plug-in slot 31. The linkage shaft 3 is installed with a pressure sensor 33 on the bottom wall of the plug-in slot 31. When the pressure sensor 33 is subjected to the pressure of the filter plate 5, the pressure sensor 33 transmits a signal to the drive motor 4, and the drive motor 4 drives the linkage shaft 3 to rotate 90 degrees.

[0043] In the initial state, the four filter plates 5 are in four states, wherein the filter plate 5 is located in the box body 1 and is horizontal, which is the first state; the filter plate 5 is vertical and located on the upper side of the linkage shaft 3, which is the second state; the filter plate 5 is horizontal and located in the accommodating chamber 2, which is the third state; the filter plate 5 is vertical and located on the lower side of the linkage shaft 3, which is the fourth state; when the filter plate 5 is in the first state, the rainwater in the box body 1 is filtered. When impurities such as leaves gradually accumulate on the surface of the filter mesh 51, the circulation efficiency of rainwater will be greatly reduced, causing rainwater to accumulate on the filter plate 5. When the weight of rainwater reaches a certain level, under the action of gravity, the filter plate 5 is driven to descend and contact with the pressure sensor 33. At this time, the pressure sensor 33 transmits a signal to the drive motor 4, and the drive motor 4 drives the filter plate 5 to rotate from the first state to the second state, and the filter plate 5 originally in the fourth state rotates to the first state, that is, the filter plate 5 in the fourth state will be replaced to realize the filtering operation of subsequent rainwater, that is, the gravity generated by the accumulation of rainwater causes the filter plate 5 to rotate, and then the filter plate 5 can be continuously replaced to ensure the circulation efficiency of rainwater. In addition, there are no leaves piled up on the filter plate 5 in the box body 1 or the amount of leaves piled up is very small. When the amount of rainwater is large and turbulent, the rainwater cannot flow downward from the filter net 51 in time, and the rainwater will also accumulate. When the weight generated by the accumulation is large, the filter plate 5 will slide downward and contact the pressure sensor 33, so that the linkage shaft 3 drives the filter plate 5 to rotate. In the process of the filter plate 5 rotating from the horizontal state to the vertical state, an unobstructed flow gap will gradually exist between the filter plate 5 and the box body 1, and part of the rainwater will also be diverted from the storage bin 2, thereby ensuring rapid drainage in the case of turbulent rainwater.

[0044] Reference Figure 1 , Figure 2 and Figure 4 Two driving chambers 13 are installed on the outer wall of the box body 1, corresponding to the two ends of the linkage shaft 3 respectively. The ends of the linkage shaft 3 extend into the driving chambers 13. The driving motor 4 is fixedly installed in one of the driving chambers 13, and the driving motor 4 drives the linkage shaft 3 to rotate by means of gear rotation; in the other driving chamber 13, a one-way wheel 6 is coaxially fixed on the linkage shaft 3, and a pawl 61 is rotatably connected to the one-way wheel 6. A ratchet 7 is fixedly installed on the inner wall of the driving chamber 13, and the ratchet 7 is located on the peripheral side of the one-way wheel 6, and the pawl 61 is meshed with the ratchet teeth of the ratchet 7. A contact tension spring 62 is fixedly connected to the one-way wheel 6, and the other end of the abutment tension spring 62 is connected to the pawl 61.

[0045] When the gravity is relatively large, the filter plate 5 may drive the linkage shaft 3 to rotate downward. Through the cooperation of the ratchet 7 pawl 61, the linkage shaft 3 can only move in one direction, thereby preventing the linkage shaft 3 from rotating downward, thereby ensuring the smooth replacement of the filter plate 5.

[0046] Reference Figure 1 , Figure 5 and Figure 6 A scraper 8 is slidably connected to the filter plate 5, and the scraper 8 is used to scrape off leaf impurities on the surface of the filter screen 51. A sliding groove 52 is provided on one side of the filter screen 51 of the filter plate 5, and a sliding block 81 that slidably cooperates with the sliding groove 52 is integrally formed on the side of the scraper 8. A first connecting shaft 9 and a second connecting shaft 10 are rotatably connected inside the filter plate 5. The first connecting shaft 9 is located on a side close to the linkage shaft 3, and the second connecting shaft 10 is located on a side away from the linkage shaft 3. A first pulley 91 is coaxially fixed on the first connecting shaft 9, and a second pulley 101 is coaxially fixed on the second connecting shaft 10. A belt 20 is wound around the first pulley 91 and the second pulley 101. A coil spring 53 is installed on one side of the filter plate 5 located on the first connecting shaft 9, and a pull rope 30 is fixedly connected to the free end of the coil spring 53. A winding wheel 102 is also coaxially fixed on the second connecting shaft 10, and the end of the pull rope 30 away from the coil spring 53 is fixed to the winding wheel 102, and the sliding block 81 is fixedly connected to the pull rope 30. A driving member for driving the first connecting shaft 9 to rotate is provided on the box body 1.

[0047] During the rotation of the filter plate 5 from the first state to the second state, the scraper 8 does not move. When the filter plate 5 rotates from the second state to the third state, the driving member drives the first connecting shaft 9 to rotate, and the first pulley 91 on the first connecting shaft 9 drives the second pulley 101 to rotate through the belt 20. The second pulley 101 drives the winding wheel 102 to rotate through the first connecting shaft 9. The winding wheel 102 winds the pull rope 30, thereby driving the scraper 8 to slide, thereby realizing the action of clearing the leaves on the surface of the filter net 51.

[0048] Reference Figure 2 , Figure 3 and Figure 6 The driving member is configured as a rack 40, and the rack 40 is in a quarter arc shape. The end of the first connecting shaft 9 extends out of the filter plate 5 and extends out of the end of the linkage shaft 3 from the plug-in slot 31. A gear 92 is coaxially fixed to the end of the first connecting shaft 9. When the filter plate 5 is in the second state, the gear 92 just meshes with the rack 40. When the filter plate 5 is in the third state, the gear 92 meshes with the end of the rack 40.

[0049] When the filter plate 5 rotates from the second state to the third state, the gear 92 moves on the rack 40, and the gear 92 rotates, driving the first connecting shaft 9 to rotate, thereby realizing the movement of the scraper 8. When the filter plate 5 rotates from the third state to the fourth state, the gear 92 and the rack 40 are separated, and at this time, under the action of the coil spring 53, the pull rope 30 is reset, that is, the scraper 8 is quickly reset.

[0050] Reference Figure 3 and Figure 7The linkage shaft 3 is located between adjacent filter plates 5 and is fixedly connected with a baffle 50, and the baffle 50 and the adjacent filter plates 5 are arranged at an angle of 45 degrees. An extension groove 82 is provided on the scraper 8, and the scraper 8 is slidably connected with an extension plate 83 in the extension groove 82. A return spring 84 is installed in the extension groove 82 of the scraper 8, and one end of the return spring 84 is connected to the inner wall of the extension groove 82, and the other end is connected to the extension plate 83. The end of the extension plate 83 is wedge-shaped and fits the surface of the baffle 50. In the initial state, the extension plate 83 is in a compressed state and the end of the extension plate 83 abuts against the baffle 50.

[0051] When the filter plate 5 rotates from the first state to the second state, the leaves on the filter screen 51 will fall downward due to gravity. Since the leaves are relatively moist and have a certain weight, the leaves will not float. Instead, the leaves will fall directly and accumulate on the baffle 50 and the scraper 8. When the filter plate 5 rotates from the second state to the third state, the scraper 8 will drive the leaves to move to the side away from the linkage shaft 3. At this time, the leaves will fall toward the inner wall of the storage bin 2 along a parabola-like state, thereby preventing them from falling onto the filter plate 5 rotating from the third state to the fourth state. In practice, when the filter plate 5 is in the second state, some relatively dry leaves will fall on the filter plate 5 in the third state. The weight of these leaves is relatively low. When the filter plate 5 in the third state rotates to the fourth state, the gear 92 and the rack 40 are separated. Under the action of the coil spring 53, the pull rope 30 is reset, that is, the scraper 8 is driven to reset quickly. The scraper 8 can clean the surface of the filter screen 51 again. Because the scraper 8 is reset quickly, after the scraper 8 is reset, the sliding block 81 collides with the end of the sliding groove 52, generating a certain vibration force, causing the filter screen 51 to vibrate, and then the leaves on the upper surface of the filter screen 51 can be shaken off into the receiving chamber 2, thereby ensuring the cleanliness of the surface of the filter screen 51. When the scraper 8 slides away from the linkage shaft 3, the extension plate 83 will gradually extend outward to expand the area, so as to further support the leaves and prevent the leaves from falling directly onto the filter screen 51 on the lower side.

[0052] In practice, there will be leaves attached to the side of the filter plate 5 close to the receiving bin 2 in the fourth state, but there are fewer leaf impurities in this case. When it rotates to the first state, the leaves are located on the lower side of the filter net 51 and can be discharged by the flushing of rainwater. Since the number is small, there will be no blockage.

[0053] Reference Figure 1 , Figure 8 , Fig. 9 and Fig.10An arc plate 60 is installed at the lower side wall of the accommodating bin 2 located at the avoidance opening 12. The arc plate 60 extends into the accommodating bin 2. The trajectory of the arc plate 60 is the same as the rotation trajectory of the filter plate 5. A drop opening 70 is formed between the upper end of the arc plate 60 and the inner wall of the accommodating bin 2. A accommodating space 21 for accommodating leaves and debris is formed between the bottom wall of the accommodating bin 2 and the arc plate 60.

[0054] By extending the arc plate 60 upward into the storage compartment 2, the space for mobile phone leaves at the bottom of the storage compartment 2 is increased. The original storage space was the space between the lower side wall of the avoidance opening 12 and the bottom wall of the storage compartment 2, and now it is the space between the upper end of the arc plate 60 and the bottom wall of the storage compartment 2. In addition, when the filter plate 5 rotates from the second state to the third state, the scraper 8 moves, and most of the leaf impurities will enter the storage bin 2 from the drop port 70; when the rainwater is relatively turbulent, the pressure sensor 33 will be continuously triggered, that is, the filter plate 5 will be in a state of continuous rotation, a large amount of rainwater will enter the storage bin 2, and a part of it will flow downward from the filter screen and be discharged downward along the arc plate 60, and during the rotation of the filter plate 5, the two upper filter plates 5 will be in a V-shaped state. At this time, the rainwater will directly rush into the storage bin 2 and will accumulate on the surface of the filter plate 5. Subsequently, when the filter plate 5 rotates, it can drive the rainwater to impact the inner wall of the storage bin 2, and finally reflect and fall on the arc plate 60 for discharge. That is, through the setting of the arc plate 60, in the case of turbulent rainwater, the rainwater can be guided and discharged as much as possible to prevent the rainwater from accumulating in the box body 1 and the storage bin 2.

[0055] The bottom wall of the storage bin 2 is detachably connected with a bottom cover 22, and the bottom cover 22 can be connected to the bottom of the storage bin 2 by threaded connection or the like. The bottom cover 22 is periodically removed to clean the storage bin 2.

[0056] The implementation principle of a fluid filtering structure in an embodiment of the present application is as follows: when rainwater enters the box body 1, under the action of the filter net 51, leaf impurities in the rainwater can be filtered, thereby preventing leaves and other impurities from clogging the pipe. However, in long-term filtering operations, leaves and other impurities will clog the filter net 51, which will also cause blockage, thereby causing rainwater to accumulate on the filter plate 5. When the accumulated gravity reaches a certain level, it will drive the filter plate 5 to descend and contact the pressure sensor 33. The pressure sensor 33 transmits a signal to the drive motor 4. The drive motor 4 drives the linkage shaft 3 to rotate 90 degrees, thereby causing the filter plate 5 in the first state to rotate to the second state, and the filter plate 5 in the fourth state to rotate to the first state, and subsequent rainwater filtering operations are performed to prevent the clogging of the filter net 51 by leaves and other impurities, resulting in a decrease in rainwater circulation efficiency.
