[0027] Install the device at the drainage position of the sunken green space, bury the overflow pipe body 1 into the soil, and make the upper port of the overflow pipe body 1 flush with the soil. Build a space on both sides of the side pin 4 with bricks and stones to facilitate the operation of the side pin 4. In the normal state, the rotating plate 22 is attached to the inner wall of the overflow pipe body 1. Multiple groups of rotating plates 22 are connected by a flexible cloth, similar to an umbrella, which can block large particles and prevent the inside of the overflow pipe body 1 from being blocked. When the rainfall is small, the rainwater is discharged into the inside of the overflow pipe body 1 through the first drain hole 3 and then discharged through the second drain hole 21. If the rain is heavy, at this time, pull out the two side pins 4 from the pin holes 13 to separate the support arm 10 from the overflow pipe body 1. Then move the cover plate 2 upward. The cover plate 2 drives the support arm 10 to move upward. When the support arm 10 moves to the topmost pin hole 13 position, insert the side pin 4 again to reconnect the overflow pipe body 1 and the support arm 10. At this time, under the support of the support arm 10, the cover plate 2 is above the overflow pipe body 1, opening the space between the cover plate 2 and the overflow pipe body 1 to drain the heavy rainfall.

Under the movable connection between the central threaded rod 12 and the moving block 19, the central threaded rod 12 drives the moving block 19 to move upward inside the chute 9. The moving block 19 drives the sliding sleeve 11 to move upward on the surface of the central sleeve 7. The sliding sleeve 11 drives the connecting arm 23 to rotate through the right linkage shaft 24. Under the support of the bearing plate 16, the connecting arm 23 drives the rotating plate 22 and the rotating block 25 to rotate around the movable shaft 20, so that multiple groups of rotating plates 22 rotate towards the central position, so that the rotating plates 22 are away from the inner wall of the overflow pipe body 1, opening the space inside the overflow pipe body 1 to facilitate the drainage of heavy rainfall, realizing the convenient linkage centering rotation to open the internal space of the overflow pipe body, facilitating the lifting and moving to adjust the position of the cover plate to open the overflow port to adapt to heavy rainfall, and improving the convenience of drainage at the overflow port;

[0028] A chute 9 is installed on the side wall of the central sleeve 7, and a central threaded sleeve 14 is installed inside the central sleeve 7;

[0029] A central threaded rod 12 is installed inside the central threaded sleeve 14, and the central threaded rod 12 is threadedly connected to the central threaded sleeve 14.

Side threaded rods 17 are installed at the bottom ends of the side handles 6, and the side threaded rods 17 are movably connected to the overflow pipe body 1;

[0031] The surfaces of the side threaded rods 17 are all sleeved with side threaded sleeves 18, and the side threaded sleeves 18 are threadedly connected to the side threaded rods 17. The side threaded sleeves 18 are slidably connected to the overflow pipe body 1, and the side threaded sleeves 18 are connected to the cross frame 8;

[0032] Two groups of support arms 10 are installed at the bottom end of the cover plate 2. A plurality of pin holes 13 are installed on the outer wall of the overflow pipe body 1 on one side of the support arm 10. A side pin 4 is slidably installed inside a group of pin holes 13, and the side pin 4 extends into the support arm 10;

[0033] When maintenance of the rotating plate 22 is required, first remove the cover plate 2, rotate the side handle 6, drive the side threaded rod 17 to rotate by the side handle 6. Under the threaded connection between the side threaded rod 17 and the side threaded sleeve 18, and under the sliding fit between the side threaded sleeve 18 and the overflow pipe body 1, drive the side threaded sleeve 18 to move upward by the side threaded rod 17. Drive the cross frame 8 and the whole device to move upward by a plurality of side threaded sleeves 18, so as to move the whole device to the outside of the overflow pipe body 1, thereby completing its maintenance, realizing convenient lifting and moving maintenance, and improving the convenience of maintaining the device.

[0034] Working principle: Install the device at the drainage position of the sunken green space, bury the overflow pipe body 1 into the soil, and make the upper port of the overflow pipe body 1 flush with the soil. Build spaces on both sides of the side pin 4 with bricks and stones to facilitate the operation of the side pin 4. In the normal state, the rotating plate 22 is attached to the inner wall of the overflow pipe body 1. Flexible fabrics are used to connect multiple groups of rotating plates 22, similar to an umbrella, which can block large particles and prevent the inside of the overflow pipe body 1 from being blocked. When the rainfall is small, rainwater is discharged into the inside of the overflow pipe body 1 through the first drain hole 3 and then discharged through the second drain hole 21. If the rainfall is large, at this time, pull out the two side pins 4 from the pin holes 13 to separate the support arm 10 from the overflow pipe body 1. Then move the cover plate 2 upward. The cover plate 2 drives the support arm 10 to move upward. When the support arm 10 moves to the pin hole 13 at the topmost position, insert the side pin 4 again to reconnect the overflow pipe body 1 and the support arm 10. At this time, supported by the support arm 10, the cover plate 2 is above the overflow pipe body 1, opening the space between the cover plate 2 and the overflow pipe body 1 to drain a large amount of rainwater. Drive the central threaded rod 12 to rotate by the central handle 5. The central threaded rod 12 moves upward inside the central threaded sleeve 14. The central threaded rod 12 drives the moving block 19 to move upward inside the chute 9. The moving block 19 drives the sliding sleeve 11 to move upward on the surface of the central sleeve 7. The sliding sleeve 11 drives the connecting arm 23 to rotate through the right linkage shaft 24. Supported by the bearing plate 16, the connecting arm 23 drives the rotating plate 22 and the rotating block 25 to rotate around the movable shaft 20, so that multiple groups of rotating plates 22 rotate towards the central position, so that the rotating plates 22 move away from the inner wall of the overflow pipe body 1, opening the space inside the overflow pipe body 1 to facilitate draining a large amount of rainwater. When maintenance of the rotating plate 22 is required, first remove the cover plate 2 and rotate the side handle 6. The side handle 6 drives the side threaded rod 17 to rotate. Under the threaded connection between the side threaded rod 17 and the side threaded sleeve 18 and the sliding fit between the side threaded sleeve 18 and the overflow pipe body 1, the side threaded rod 17 drives the side threaded sleeve 18 to move upward. Multiple groups of side threaded sleeves 18 drive the cross-frame 8 and the whole device to move upward to move the whole device to the outside of the overflow pipe body 1, so as to complete its maintenance and complete the use of the overflow port device for overflow drainage of rainwater in the sunken green space.
