Description

Roof siphon drainage system

Technical Field

The utility model relates to a roofing siphon drainage system belongs to siphon drainage field.

Background

The drainage mode of rainwater on the roofing at present mainly divide into two kinds: one is the traditional gravity type rainwater drainage system, the principle is that the slope of the roof structure is utilized, rainwater naturally flows into a rainwater hopper on the roof, and then the rainwater and air are mixed together and fall along a vertical pipe under the action of gravity; the drainage efficiency is low, the number of pipelines is large, the pipe diameter of the pipelines is large, the gradient of 1% -3% is required, the installation is complicated, the problem that drainage is not timely occurs sometimes when the rainfall is large, and the like, although the efficiency of the traditional siphon drainage system is much higher than that of the gravity drainage system, the existing siphon drainage system has some defects; some buildings are too high in height, the vertical pipe is too long in length, the downward gravitational potential energy of water in the vertical pipe is larger and larger, the ground surface buildings can be seriously impacted, on the other hand, the negative pressure of a drainage system exceeds the standard, no buffer measure is provided for downward water flow in the vertical pipe, and the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims at providing a roofing siphon drainage system, rivers get into the connecting pipe and get into in suspension pipe through the funnel that entries, flow into the riser again in, rivers will be through first buffer plate, second buffer plate and third buffer plate this moment, and decurrent rivers play the cushioning effect.

The utility model discloses a solve the technical scheme who takes of above-mentioned problem and do: the utility model provides a roofing siphon drainage system, includes into the funnel of intaking, the connecting pipe, suspension tube and riser, the bottom and the connecting pipe sealing connection of the funnel of intaking, the bottom and the suspension tube connection of connecting pipe, suspension tube level is placed, flange and riser sealing connection are passed through to the one end of suspension tube, the riser bottom is equipped with the delivery port, the top of delivery port is from last to being equipped with first buffer chip, second buffer chip and third buffer chip down in proper order in the riser.

Preferably, first buffer piece, second buffer piece and third buffer piece are fixed respectively on the inside of riser, and the length of first buffer piece, second buffer piece and third buffer piece increases in proper order.

Preferably, a filter screen is arranged at the top of the water inlet funnel.

Preferably, the water inlet funnel and the water outlet are both trumpet-shaped.

Preferably, the ratio of the inner diameters of the connecting pipe and the hanging pipe is 1:2, and the inner diameters of the hanging pipe and the stand pipe are consistent.

Preferably, the bottom of the connecting pipe is provided with a clamping block on the hanging pipe.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of a roof siphon drainage system of the present invention;

FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;

wherein, 1, a water inlet funnel; 2. a connecting pipe; 3. a hanger tube; 4. a flange; 5. a riser; 6. a first buffer sheet; 7. a second buffer sheet; 8. a third buffer sheet; 9. a water outlet; 10. a clamping block; 11. and (5) filtering by using a filter screen.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The attached drawings are simplified schematic diagrams, and merely illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

In a first specific embodiment, please refer to fig. 1-2, a siphon drainage system for roof includes a water inlet funnel 1, a connecting pipe 2, a hanging pipe 3 and a vertical pipe 5, wherein the bottom of the water inlet funnel 1 is hermetically connected to the connecting pipe 2, the bottom of the connecting pipe 2 is connected to the hanging pipe 3, the hanging pipe 3 is horizontally disposed, one end of the hanging pipe 3 is hermetically connected to the vertical pipe 5 through a flange 4, a water outlet 9 is disposed at the bottom of the vertical pipe 5, a first buffer sheet 6, a second buffer sheet 7 and a third buffer sheet 8 are sequentially disposed in the vertical pipe 5 from top to bottom above the water outlet 9, the first buffer sheet 6, the second buffer sheet 7 and the third buffer sheet 8 are respectively fixed to the inside of the vertical pipe 5, and the lengths of the first buffer sheet 6, the second buffer sheet 7 and the third buffer sheet 8 are sequentially increased, at this time, the inner diameters of water flows in the first buffer sheet 6, the second buffer sheet 7 and the third buffer sheet 8 are sequentially decreased, the rainwater that makes the quick flow down carries out gradual speed reduction and step-down to can keep the negative pressure in negative pressure zone to keep stable, guarantee good drainage effect, the top of funnel 1 of intaking is equipped with filter screen 11, and when the roofing has more impurity, and when inconvenient clearance, filter screen 11 can separate impurity and water, prevents that impurity from getting into and blocking the water route in hanging pipe 3 or riser 5, funnel 1 of intaking all is loudspeaker form with delivery port 9, the internal diameter ratio of connecting pipe 2 and hanging pipe 3 is 1:2, makes rivers more smooth and easy, the internal diameter of hanging pipe 3 and riser 5 is unanimous, the bottom of connecting pipe 2 is equipped with grip block 10 on hanging pipe 3, prevents to connect 2 and rocks.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
