Detailed Description

The present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 1-5.

Example (b): a rain funnel, comprising: the upper end of the cylindrical body 5 is provided with an opening, the middle part of the bottom plate of the cylindrical body 5 is connected with an inner cylinder 2 with two openings at two ends, and the height of the inner cylinder 2 is lower than that of the cylindrical body 5; the upper end of the side surface of the inner barrel 2 is provided with a plurality of inner filtering holes 21, the lower end space between the barrel-shaped body 5 and the inner barrel 2 forms a solid collecting space 9, two sides of the lower end of the inner barrel 2 are respectively provided with an outer shaft hole, a partition plate 15 matched with the inner barrel 2 is arranged in the inner barrel 2, the partition plate 15 is in clearance fit with the inner barrel 2, the partition plate 15 is provided with a plurality of through holes 16, two sides of the partition plate 15 are provided with inner shaft holes, a spring 20 and a rotating shaft 17 are arranged in each inner shaft hole, one end of the rotating shaft 17 is abutted against the spring 20, the other end of the rotating shaft 17 extends out of each inner shaft hole and is inserted into each outer; the upper end of the inner cylinder 2 is connected with a plurality of cross rods 14, floating blocks 11 are lapped above the cross rods 14, connecting holes 12 are formed in the middle of the floating blocks 11, a pull rope 13 is connected between each connecting hole 12 and one of the through holes 16, and when the floating blocks 11 float upwards, the floating blocks 11 pull the partition plates 15 to rotate.

When the technical scheme works, the lower end of the inner barrel 2 can be sleeved with a water flowing pipe, and water in the rainwater funnel flows to the water flowing pipe. When the rainwater amount is small, the rainwater on the roof flows to a rainwater funnel along the water tank and enters between the cylindrical body 5 and the inner cylinder 2, and when the rainwater overflows the lowest inner filtering hole 21 on the inner cylinder 2, the rainwater enters the inner cylinder 2 and flows to the water flowing pipe through the partition plate 15; when solid particles enter the cylindrical body 5, the particles with high density sink in the solid collecting space 9, and the particles with low density float above the solid collecting space 9; can prevent the blocking in the water inlet pipe. When the amount of rainwater is large, the liquid level of rainwater continuously rises between the cylindrical body 5 and the inner cylinder 2 until the rainwater passes through the inner cylinder 2 and directly flows downwards through the partition plate 15, and the aperture of the through hole 16 is larger than that of the inner filtering hole 21; the drainage rate is increased; the partition plate 15 is mainly used for blocking some solid objects with larger volume so as to avoid blocking a rainwater system; when the amount of rainwater is very large, so that rainwater begins to accumulate in the inner barrel 2, when the rainwater level in the inner barrel 2 exceeds the cross rod 14, the floating block 11 begins to float upwards under the buoyancy of water, and drives the partition plate 15 to rotate through the pull rope 13, so that the gap between the partition plate 15 and the inner barrel 2 is gradually increased, the flowing speed is gradually increased, and when the rainwater level in the inner barrel 2 drops below the cross rod 14, the partition plate 15 is reset under the acting force of the torsion spring 18. Preferably, the through-hole 16 of the partition 15 for connecting the pull cord 13 is located at the outer side and at equal or similar distance from the two rotation shafts 17. The floating block 11 may be a foam block, a wood block, or the like.

Furthermore, the inner side surface of the inner cylinder 2 is provided with a limiting block 10, and the limiting block 10 is abutted to the partition plate 15.

When the torsion spring 18 is installed, it is generally difficult to ensure that the torsion spring 18 does not have a little torsion force when the partition 15 is in a horizontal state; therefore, a limiting block 10 is arranged, the limiting block 10 is positioned at the same side of the through hole 16 connected with the pull rope 13, namely, in an initial state, the torsion spring 18 has a certain torsion force and drives the partition plate 15 to turn over towards the direction of the limiting block 10; meanwhile, the partition plate 15 can be prevented from being turned over easily when rainwater entering the inner barrel 2 is distributed uniformly.

Furthermore, a plurality of inserting holes 19 are formed in the upper end of the inner barrel 2, the inserting holes 19 are connected with the inserting rods 4, and the limiting plates 1 are connected to the upper ends of the inserting rods 4.

In order to prevent the floating block 11 from floating upwards and possibly floating out of the inner barrel 2 when the rainwater amount is larger; after the limiting plate 1 and the inserted rod 4 are arranged, the floating block 11 is limited inside.

Furthermore, an outer cylinder 3 is sleeved outside the inner cylinder 2, and an outer filtering hole 7 matched with the inner filtering hole 21 is formed in the upper end of the outer cylinder 3.

After the outer barrel 3 is arranged, rainwater needs to enter the inner barrel 2 through the outer filtering holes 7 and the inner filtering holes 21. The size of the actual filtering hole can be adjusted by rotating the outer cylinder 3; the actual filter holes are the size of the overlapping portions of the inner filter holes 21 and the outer filter holes 7.

Further, the lower end of the outer cylinder 3 is connected with an annular plate 8 matched with the interior of the cylindrical body 5, and the lower end of the annular plate 8 is abutted against the upper end face of the bottom plate of the cylindrical body 5.

After the annular plate 8 is arranged, solid garbage in the cylindrical body 5 can be conveniently cleaned; when the cleaning is needed, the outer cylinder 3 is directly taken out, and then the annular plate 8 of the outer cylinder 3 is cleaned.

Furthermore, the lower end face of the cylindrical body 5 is provided with an annular concave hole which is coaxial with the inner cylinder 2, and the annular concave hole is connected with a connecting pipe 6.

The connecting pipe 6 is provided to facilitate connection with the flow pipe.

A building rainwater system comprises the rainwater funnel.
