DETAILED DESCRIPTION

[0021] The present application will be further described in detail below with reference to the accompanying drawings and examples.

[0022] As Figure 1As shown: a drainage structure for draining roof rainwater, comprising a siphon rainwater inlet 1, the bottom of which is connected to extend a rainwater suspension pipe 2, and the rainwater is extended to a rainwater standpipe 4, a maximum negative pressure point 3 is formed at the top of the rainwater standpipe 4, the bottom end of the rainwater standpipe 4 is connected to a buried pipe 5 and flows out through a rainwater outlet pipe 6, an inspection well 12 is provided on the ground to communicate with the atmosphere, and the rainwater outlet pipe 6 leads the rainwater out to the inspection well 12.

[0023] The above structure has no slope, flexible distribution points, small influence on building space, flexible pipeline layout, and can meet the needs of building material selection and construction process.

[0024] Considering that when the rainwater is extended to the rainwater standpipe 4, a maximum negative pressure point 3 is formed at this position, so that a large amount of fallen leaves or long-term accumulated concrete blocks and other sundries are easily quickly accumulated and blocked, therefore, the present scheme further flexibly assembles a filter assembly 7 at the inlet of the rainwater standpipe 4 to overcome this problem.

[0025] Referring to the accompanying drawings Figures 2-4 The filter assembly 7 comprises a filter cover 8, the filter cover 8 is laterally provided with a water inlet slot 9, and is in communication with a through hole 18 opened at the bottom, and a filter seat 10 is arranged in the filter cover 8, the filter seat 10 is independent of the internal space of the filter cover 8, and the filter seat 10 is in communication with the bottom of the filter cover 8 to drain water.

[0026] A plurality of through grooves 16 penetrating the side wall are laterally provided on the filter seat 10, and a hemispherical body 17 is formed at the bottom, and the bottom of the filter cover 8 also forms a larger hemispherical body 17, so that the filter seat 10 can move arbitrarily in the filter cover 8 under the action of negative pressure, thereby avoiding being blocked on one side, that is, after being blocked, the pressure change drives the entire filter seat 10 to move until it is unblocked (such as a large amount of fallen leaves or long-term accumulated concrete blocks blocking the roof), and the force is balanced, secondly, the filter cover 8 can block part of sundries, and finally realize unblocked drainage.

[0027] The filter cover 8 is laterally provided with a long groove 19 at the circumferential extension of the through hole 18, which is convenient for rapid water passing.

[0028] The bottom of the filter cover 8 is connected with an annular base 11, the annular base 11 is laterally provided with a support 15, the support 15 is hingedly connected with a rotating rod 14, and the outer end of the rotating rod 14 is connected with an arc-shaped block 13, wherein the hinge connection of the support 15 is fastened by a screw rod and a bolt, and can be fixed after adjusting the position of the arc-shaped block 13. In use, the position of the arc-shaped block 13 is adjusted according to the pipe diameter of the rainwater standpipe 4, so that the two arc-shaped blocks 13 can be clamped on the rainwater standpipe 4, and can be suitable for rainwater standpipes 4 of different pipe diameters, and have wider applicability.

[0029] At the same time, the arc-shaped block 13 needs to be clamped at the top diameter of the rainwater vertical pipe 4, which is convenient for fastening the bolt after adjustment, and can realize sufficient filtering at the maximum negative pressure of the top of the rainwater vertical pipe 4.
