Description

Technical Field

[0001] The utility model relates to a roof drainage mechanism, in particular to a closed energy dissipation rainwater dustpan. Background Art

[0002] When there are high and low spans on the roof, rainwater on the high roof is first drained to the low roof, and then drained to the ground through the drainage grooves on the low roof. A transition wall is arranged between the high and low span roofs. In order to protect the transition wall from being eroded by the falling drainage and to protect the drainage structure of the low roof, a rainwater dustpan is generally arranged on the low roof to catch the rainwater drainage from the falling high roof and eliminate the impact kinetic energy of the falling rainwater. Therefore, an energy dissipating rainwater dustpan comes into being; the utility model patent with application number 2020233085800 and name “an energy dissipating rainwater dustpan” discloses a structure of an energy dissipating rainwater dustpan. The mechanism has a right-angled trapezoidal shape. It eliminates the impact kinetic energy of falling rainwater by arranging an inclined flap and a water outlet on the inclined flap. At the same time, it blocks the drainage by an inclined baffle to prevent it from scouring the transition wall. The energy-dissipating rainwater dustpan has the following problems: (1) Its top is open, and the falling rainwater will rush out of the dustpan through the open top. At the same time, leaves and debris on the roof can easily enter the dustpan through the open top, causing the drainage dustpan to be blocked; (2) The inclined baffle on the top cannot completely prevent the drainage from splashing back onto the wall. The inclined baffle also complicates the structure of the energy-dissipating dustpan, which is not conducive to the maintenance and replacement of the dustpan. Summary of the invention

[0003] The utility model provides a closed energy dissipation rainwater dustpan, which solves the technical problems of poor energy dissipation effect and easy clogging of the existing energy dissipation rainwater dustpan.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A closed energy dissipation rainwater dustpan comprises a closed rectangular box and a vertical drainage pipe from a high roof to a low roof. The rectangular box is arranged on a low roof directly below the vertical drainage pipe from a high roof to a low roof. A trumpet-shaped water inlet which is small at the top and large at the bottom is arranged on the top plate of the rectangular box. The upper end of the trumpet-shaped water inlet is connected with the lower end of the vertical drainage pipe from the high roof to the low roof. A conical protrusion is arranged on the bottom surface of the rectangular box directly below the trumpet-shaped water inlet. A horizontal hinge seat for a hanging plate is arranged on the lower bottom surface of the top plate in the rectangular box in front of the trumpet-shaped water inlet. A hanging plate is movably suspended on the horizontal hinge seat for the hanging plate. Vertical long through holes are arranged at intervals on the hanging plate. A bottom drainage groove is arranged at the lower end of the hanging plate. The front vertical plate of the rectangular box is a shutter.

[0006] The outer facade of the conical protrusion block is a hyperbolic rotating body; impact buffer plastic pins are arranged on the hanging plate, and the hanging plate is hinged on the horizontal hinge seat of the hanging plate through the top pin shaft; the bottom end plate of the rectangular box is an inclined plate with a high rear and a low front.

[0007] On the shutter, blade pin shafts are arranged at intervals along the up and down vertical directions, and blades are hinged on the blade pin shafts.

[0008] The utility model improves the main body strength of the rainwater dustpan, has strong anti-scouring performance and remarkable energy dissipation effect. Rainwater discharged from the high roof passes through the three-level energy dissipation of the conical protruding block, the hanging plate and the shutter in sequence, which greatly reduces the impact force of the discharged rainwater. At the same time, the closed rectangular box overcomes the defect of water drainage splashing back to the wall, thereby protecting the wall from scouring. The form of the shutter water outlet also has the effect of beautifying the rainwater dustpan. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is described in detail below with reference to the accompanying drawings:

[0014] A closed energy dissipation rainwater dustpan comprises a closed rectangular box body 1 and a drainage riser 3 from a high roof to a low roof. The rectangular box body 1 is arranged on a low roof directly below the drainage riser 3 from the high roof to the low roof. A trumpet-shaped water inlet 2 which is small at the top and large at the bottom is arranged on the top plate of the rectangular box body 1. The upper end of the trumpet-shaped water inlet 2 is connected with the lower end of the drainage riser 3 from the high roof to the low roof. Rainwater on the high roof enters the closed rectangular box body 1 in sequence through the drainage riser 3 from the high roof to the low roof and the trumpet-shaped water inlet 2. A conical convex block 5 is arranged on the bottom surface of the rectangular box body 1 directly below the trumpet-shaped water inlet 2. The conical convex block 5 is a hyperbolic rotating body. After the falling drainage falls on the conical convex block 5, it is diverted in the closed rectangular box body 1. Since the left and right sides and the rear side of the rectangular box body 1 are in a closed state, the diverted rainwater can only impact in the forward direction. A hanging plate horizontal hinge seat 6 is arranged on the lower bottom surface of the top plate in the rectangular box body 1 on the front side of the trumpet-shaped water inlet 2, and a hanging plate 7 is movably suspended on the hanging plate horizontal hinge seat 6. Vertical long strip through holes 9 are arranged at intervals on the hanging plate 7, and a bottom drainage groove 11 is arranged at the lower end of the hanging plate 7. The rainwater impacting in the forward direction hits the hanging plate 7, so that the hanging plate 7 swings forward, and the water outlet at the lower end of the hanging plate 7 is enlarged. At the same time, a part of the rainwater passes through the hanging plate through the vertical long strip through holes 9 arranged at intervals on the hanging plate 7, thereby realizing the second energy dissipation of the drainage kinetic energy; the front side vertical plate of the rectangular box body 1 is a shutter 12, and the drainage through the hanging plate 7 finally rushes to the shutter 12, and is discharged from the shutter gaps to the outside of the rectangular box body 1, realizing the third energy dissipation of the drainage, and the impact force of the discharged rainwater is very small, which protects the safety of the roof structure and will not splash back to the wall.

[0015] The outer facade of the conical protrusion block 5 is a hyperbolic rotating body; an impact buffering plastic pin 10 is arranged on the hanging plate 7, which plays a role in buffering the impact force between the hanging plate 7 and the blinds 12. The hanging plate 7 is hinged on the hanging plate horizontal hinge seat 6 through the top pin shaft 8; the bottom end plate 4 of the rectangular box 1 is an inclined plate with a high rear and a low front, so as to facilitate the discharge of rainwater from the rainwater dustpan.

[0016] On the shutter 12, blade pins 13 are arranged at intervals along the upper and lower vertical directions, and blades 14 are hinged on the blade pins 13. The blades 14 can swing around the blade pins 13. When drainage impacts the blades 14, the blades 14 swing upward to increase the drainage gap. When drainage is small, the blades 14 swing downward to reduce the drainage gap.
