Technical Field

[0001] This utility model belongs to the field of rainwater diversion technology, and specifically relates to a rainwater diversion device. Background Technology

[0002] Rainwater diversion devices are used to efficiently collect and divert rainwater, commonly found on building roofs, in courtyards, and along roads. They utilize structures such as a ring-shaped base and top plate combined with a diversion baffle, a siphon rainwater hopper, a retractable roller shutter, or a flexible tarpaulin to direct rainwater to a storage tank, green space, or drainage system. Some devices are equipped with solar power systems, insect-control grids, and rainwater sensors, enabling automated operation and multi-functional integration, combining environmental friendliness, energy efficiency, and practicality.

[0003] Chinese Patent No. CN216428489U discloses a rainwater diversion device, which relates to the field of rainwater treatment technology. It includes a ground connection frame, a flow frame, and a connecting pipe. The flow frame is arranged parallel to the ground connection frame below it, and the connecting pipe is located at the bottom of the flow frame. The ground connection frame includes a support frame body, a diversion plate, an annular connecting frame, and a collection frame. The diversion plate is uniformly fixedly connected to the bottom of the support frame body, and the collection frame is movably connected to the top of the support frame body through a second positioning bolt.

[0004] However, the above structure still has some shortcomings. Because the top of the device will be in contact with rainwater or impurities for a long time, it is inevitable that some wear and tear will occur after long-term use. Because the top frame structure of the device is not easy to disassemble, the user also needs to disassemble the entire device to maintain and clean the structure on the top frame, which is very inconvenient.

The first locking block is located on the inner side close to the first sealing ring. The top of the first sealing ring is in contact with the bottom of the top frame. The first sealing ring is made of rubber material.

[0010] As a preferred technical solution, a connecting plate is fixedly connected to the outer wall of both the connecting frame and the traction tube. A screw hole is opened at the top of the connecting plate, a bolt is threaded to the inner side of the screw hole, a nut is threaded to the top of the bolt, and the bottom end of the nut is in contact with the top of the connecting plate.

The thickness of the anti-corrosion layer on the outer wall of the connecting frame is five millimeters, and the anti-corrosion layer on the outer wall of the connecting frame covers the outer wall of the connecting frame.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, during use, the first and second diversion plates can effectively divert and guide rainwater. The first locking block can send the second locking block into the circular groove. Adjusting the second locking block to a non-corresponding angle with the second locking groove can effectively lock the top frame position to prevent displacement. When the top frame needs to be disassembled later, the second locking block is adjusted to a corresponding angle with the second locking groove, and then the first locking block can be pulled out directly. This not only facilitates the disassembly and assembly of the top frame, but also makes it easier for users to perform individual maintenance or cleaning later.

[0016] Secondly, the protective frame effectively encloses the top of the top frame to prevent large debris or mud from entering the flow hole, thus providing good safety protection. The baffles can effectively block smaller debris to prevent large amounts of debris from entering the flow hole and causing blockage. The filter plate can also block impurities, gravel, and other debris. Furthermore, the user can remove the filter plate through the chute for subsequent cleaning. Attached Figure Description

The top frame 4 is threadedly connected to a traction pipe 17, and a filter plate 19 is slidably connected to the inner wall of the traction pipe 17. In use, the top frame 4 can effectively protect the top of the connecting frame 1. The first diversion plate 2 and the second diversion plate 6 can effectively divert and pull rainwater. The first locking block 13 can send the second locking block 14 into the circular groove 10. The second locking block 14 is adjusted to an angle that is not corresponding to the second locking groove 9, so that the top frame 4 can be effectively locked to prevent displacement. When the top frame 4 needs to be disassembled later, the second locking block 14 is adjusted to an angle corresponding to the second locking groove 9, and then the first locking block 13 can be pulled out directly. This not only makes it convenient to disassemble and install the top frame 4, but also makes it easier for users to perform individual maintenance or cleaning later.

[0025] refer to Figures 1 to 4 A retaining spring 11 matching the second retaining block 14 is installed at the bottom inner side of the circular groove 10. The bottom end of the second retaining block 14 is engaged with the top end of the retaining spring 11.

A sealing block 15 is fixedly connected to the top end of the first retaining block 13. The sealing block 15 covers the top end of the first retaining groove 8. A protrusion 16 is fixedly connected to the top end of the sealing block 15. The protrusion 16 has an arc-shaped corner. Due to the presence of the retaining spring 11, the retaining spring 11 can engage the second retaining block 14 at a secondary position, thereby effectively improving the stability of the engagement of the second retaining block 14 at a position, and also effectively improving the stability of the engagement of the top frame at a position of 4.

[0026] refer to Figures 1 to 3The top of the connecting frame 1 is fixedly connected to a first sealing ring 12, which is one centimeter thick. The first locking block 13 is located on the inner side close to the first sealing ring 12. The top of the first sealing ring 12 is in contact with the bottom of the top frame 4. The first sealing ring 12 is made of rubber material. Due to the presence of the first sealing ring 12, the rubber material has good anti-slip ability and rubber elasticity. While sealing the top frame 4, when the second locking block 14 is engaged, the rubber rebound of the first sealing ring 12 can also make the second locking block 14 engage more tightly, which can further improve the stability of the engagement of the top frame 4.

[0027] refer to Figures 1 to 5 A connecting plate 20 is fixedly connected to the outer wall of both the connecting frame 1 and the traction tube 17. A screw hole 21 is opened at the top of the connecting plate 20. A bolt 22 is threaded on the inner side of the screw hole 21. A nut 23 is threaded on the top of the bolt 22. The bottom end of the nut 23 is in contact with the top of the connecting plate 20. Due to the presence of the bolt 22, the bolt 22 can be screwed in to effectively fix the position of the traction tube 17 to prevent the traction tube 17 from shifting. At the same time, the user can also disassemble the traction tube 17 later through the thread principle for later maintenance or cleaning.

Due to the presence of the first sealing ring 12, the rubber material has good anti-slip ability and rubber elasticity. While sealing the top frame 4, after the second retaining block 14 is engaged, the first seal... The rubber rebound of ring 12 can also make the second locking block 14 lock more tightly, which can further improve the stability of the locking at point 4 of the top frame. Due to the presence of bolt 22, the screwing in of bolt 22 can effectively fix the traction pipe 17 to prevent displacement of traction pipe 17. At the same time, the user can also remove traction pipe 17 through the thread principle for later maintenance or cleaning. Due to the presence of second sealing ring 24, second sealing ring 24 can effectively seal the connection point of traction pipe 17, which can achieve a good waterproof sealing effect, thereby effectively improving the stability of water flow. Due to the presence of protective frame 5, the top of top frame 4 can be effectively blocked to prevent large garbage or mud from entering the flow hole 3, thus achieving a good safety protection effect. Its baffle 7 can effectively block smaller garbage to prevent a large amount of garbage from entering the flow hole 3 and causing blockage.
