Detailed implementation manners

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figures 1 - 10, a drainage filtration mechanism for building construction and municipal engineering, comprising a frame body 6, a filtration and cleaning mechanism, a collection mechanism, and a material shaking mechanism. Both sides of the frame body 6 are fixedly bolted with a first fixing plate 2 and a second fixing plate 5, and the first fixing plate 2 and the second fixing plate 5 are fixed to each other. The filtration and cleaning mechanism includes a first filter plate 23. The first filter plate 23 is located inside the frame body 6 and is slidably connected to the frame body 6. Two second springs 36 are welded to the top of the first fixing plate 2, and the second springs 36 are fixed to the first filter plate 23. Limiting grooves 24 are provided on the inner walls of both sides of the frame body 6. A sliding rod 25 is slidably connected in the limiting groove 24. A sliding plate 30 is fixedly bolted to the bottom of the sliding rod 25, and the sliding plate 30 is in contact with the first filter plate 23. Second sliding grooves 38 are provided on both sides of the sliding plate 30. A slider 33 is slidably connected in the second sliding groove 38. A first spring 35 is welded to the bottom of the slider 33, and the first spring 35 is fixed to the second sliding groove 38. A scraping plate 27 is welded to one side of the slider 33, and the scraping plate 27 is slidably connected to the first filter plate 23. A plurality of second protrusions 32 are welded to the upper surface of the first filter plate 23. First protrusions 31 are welded to both ends of the sliding plate 30, and the first protrusions 31 are in contact with the second protrusions 32. A connecting plate 11 is welded to the outer wall of one side of the frame body 6. A motor is fixedly bolted to the upper surface of the connecting plate 11. One end of the output shaft of the motor is fixedly bolted with a rotating shaft 12. A first connecting rod 14 is welded to one end of the rotating shaft 12. A fixed column 22 is welded to one side of the first connecting rod 14. A second connecting rod 15 is rotatably connected to the outside of the fixed column 22. A fixed seat 29 is welded to the top of the slider 33, and the second connecting rod 15 is rotatably connected to the fixed seat 29. The motor drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the first connecting rod 14 to rotate, the first connecting rod 14 drives the fixed column 22 to rotate. During the rotation of the fixed column 22, the second connecting rod 15 will swing through the fixed seat 29. While the second connecting rod 15 is swinging, it will drive the fixed seat 29 to move. The fixed seat 29 drives the sliding plate 30 to move, and the sliding plate 30 drives the first protrusion 31 to move. At this time, through the contact between the inclined surface of the first protrusion 31 and the inclined surface of the second protrusion 32, the first protrusion 31 will push the first filter plate 23 to move downward and compress the second spring 36 during the movement. When the first protrusion 31 moves between the other two second protrusions 32, the first filter plate 23 will reset under the action of the second spring 36. This cycle is repeated to make the first filter plate 23 vibrate, preventing the first filter plate 23 from being blocked by garbage. During the downward movement of the first filter plate 23, the slider 33 will move downward along the second sliding groove 38 under the action of the first spring 35. The slider 33 drives the scraping plate 27 to move downward, so that the scraping plate 27 is always in contact with the first filter plate 23. At the same time, the sliding plate 30 will drive the scraping plate 27 to move, so that the scraping plate 27 scrapes and cleans the garbage on the first filter plate 23, preventing the garbage on the first filter plate 23 from accumulating too much and affecting the first filter plate 23, and improving the filtration effect of the drainage filtration mechanism.

[0038] Particularly in the present invention, the collection mechanism includes two L-shaped plates 37, which are respectively fixed to both sides of the frame body 6 by bolts, and the L-shaped plates 37 are fixed to the first fixing plate 2. Two first chutes 8 are provided on one side of each of the two L-shaped plates 37. The same material collection box 9 is slidably connected in two adjacent first chutes 8. An outlet is provided on one side of the second fixing plate 5. Rotation holes are provided on both sides of the outlet. A rotating shaft is rotatably connected in the rotation holes. A rotating door 16 is welded to one end of the rotating shaft. The other end of the rotating shaft passes through the second fixing plate 5 and the frame body 6 and is welded with a torsion spring 18, and the torsion spring 18 is fixed to the frame body 6. Two push rods 28 are welded to the top of the sliding plate 30, and the push rods 28 can contact the rotating door 16. When the sliding plate 30 moves, it will drive the push rods 28 to move. During the movement of the push rods 28, they will first contact the rotating door 16 and push the rotating door 16 to rotate, causing the torsion spring 18 to deform and generate torsion force, so that the rotating door 16 no longer blocks the outlet. Then the scraper 27 will clean the garbage through the outlet into the material collection box 9. When the push rods 28 move to be disengaged from the rotating door 16, the rotating door 16 will be reset by the acting force of the torsion spring 18 and re-close the outlet. A sealing ring 17 is adhesively bonded to the outside of the rotating door 16, and the sealing ring 17 contacts the mounting opening. The sealing ring 17 can seal the gap between the rotating door 16 and the outlet, avoiding water leakage through the gap between the rotating door 16 and the outlet when the drainage and filtration mechanism filters water, and improving the sealing effect of the drainage and filtration mechanism. Two handles 7 are welded to the upper surface of the material collection box 9, and the handles 7 are evenly distributed. The material shaking mechanism includes a second filter plate 26. An inclined groove 20 is provided on one side of the second fixing plate 5. The second filter plate 26 is slidably connected to the inclined groove 20. A tension spring 19 is welded in the inclined groove 20, and the tension spring 19 is fixed to the second filter plate 26. When the second connecting rod 15 swings, the second filter plate 26 loses the supporting force. At this time, the second filter plate 26 will move downward along the inclined groove 20 under the action of the tension spring 19. When the second connecting rod 15 swings again to support the second filter plate 26, it will push the second filter plate 26 to move upward and stretch the tension spring 19. This cycle repeats, causing the second filter plate 26 to vibrate, and vibrating the garbage on the second filter plate 26 onto the first filter plate 23, so that the scraper 27 can also clean the garbage on the second filter plate 26. A rubber pad 21 is adhesively bonded to the top of the second connecting rod 15, and the rubber pad 21 contacts the second filter plate 26. A guide rod 34 is welded in the second chute 38, and the guide rod 34 passes through the slider 33. A shock pad 10 is adhesively bonded to the upper surface of the connecting plate 11, and the shock pad 10 is located between the motor and the connecting plate 11. The shock pad 10 can reduce the vibration effect brought by the motor to the drainage and filtration mechanism, so that the drainage and filtration mechanism is more stable and improves the stability of the drainage and filtration mechanism during use. A water inlet pipe 13 is welded to the top of the frame body 6, and the water inlet pipe 13 is communicated with the frame body 6. A water outlet pipe 3 is welded to the bottom of the frame body 6, and the water outlet pipe 3 is communicated with the frame body 6.A valve 4 is fixedly mounted on the outer side of the water outlet pipe 3 by bolts. A plurality of feet 1 are fixedly mounted on the bottom outer wall of the frame body 6 by bolts, and the feet 1 are evenly distributed. An anti-slip pad is bonded to the bottom of the feet 1, and the anti-slip pad is as long as the feet 1. When the drainage and filtration mechanism is placed on the ground through the feet 1, the anti-slip pad on the feet 1 will contact the ground. At this time, the anti-slip pad can increase the friction between the feet 1 and the ground, so that the drainage and filtration plate mechanism is placed more stably, and further improves the stability of the drainage and filtration mechanism during use.

[0039] Working principle of this embodiment: During use, the accumulated rainwater enters the frame body 6 through the water inlet pipe 13. At this time, the second filter plate 26 will first filter the rainwater, and then the first filter plate 23 will filter the rainwater again. Filtering the rainwater twice improves the filtering effect of the drainage filtering mechanism. Then, start the motor. The motor drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the first connecting rod 14 to rotate. The first connecting rod 14 drives the fixed column 22 to rotate. During the rotation of the fixed column 22, the second connecting rod 15 will swing through the fixed seat 29. While the second connecting rod 15 is swinging, it will drive the fixed seat 29 to move. The fixed seat 29 drives the sliding plate 30 to move. The sliding plate 30 drives the first convex block 31 to move. At this time, the inclined surface of the first convex block 31 contacts the inclined surface of the second convex block 32. Therefore, during the movement of the first convex block 31, it will push the first filter plate 23 downward and compress the second spring 36. When the first convex block 31 moves between the other two second convex blocks 32, the first filter plate 23 will be reset by the acting force of the second spring 36. This cycle repeats, causing the first filter plate 23 to vibrate and preventing garbage from blocking the first filter plate 23. During the downward movement of the first filter plate 23, the slider 33 will move downward along the second chute 38 under the acting force of the first spring 35. The slider 33 drives the scraper 27 to move downward, so that the scraper 27 is always in contact with the first filter plate 23. At the same time, the sliding plate 30 will drive the scraper 27 to move, so that the scraper 27 scrapes and cleans the garbage on the first filter plate 23, preventing too much garbage from accumulating on the first filter plate 23 and affecting the first filter plate 23, and improving the filtering effect of the drainage filtering mechanism. While the second connecting rod 15 is swinging, the second filter plate 26 loses the supporting force. At this time, the second filter plate 26 will move downward along the inclined groove 20 under the action of the tension spring 19. When the second connecting rod 15 swings again to support the second filter plate 26, it will push the second filter plate 26 upward and stretch the tension spring 19. This cycle repeats, causing the second filter plate 26 to vibrate and vibrating the garbage on the second filter plate 26 onto the first filter plate 23, so that the scraper 27 can also clean the garbage on the second filter plate 26. While the sliding plate 30 is moving, it will drive the push rod 28 to move. During the movement of the push rod 28, it will first contact the rotating door 16 and push the rotating door 16 to rotate and cause the torsion spring 18 to deform and generate torsion, so that the rotating door 16 no longer blocks the discharge port. Then, the scraper 27 will clean the garbage through the discharge port into the collection box 9. When the push rod 28 moves out of contact with the rotating door 16, the rotating door 16 will be reset by the acting force of the torsion spring 18 and re-close the discharge port.
